    For ten years, the Negawatt association has taken a fresh look at our ways of consuming and producing energy. After the realisation of its 2011 scenario, the association has wished to complete this work with a reflexion full of ideas and operational measures and addressed to all citizens and to decision-makers. This manifesto describes with pedagogy and lucidity a possible and desirable path to get out of our energy and climate crises. Contents: 1 - Energy in crisis; 2 - Energy in its all forms; 3 - From the approach to the scenario: preparing the energy transition; 4 - Buildings and energy transition; 5 - Key-sectors of the transition: transports, industry and agriculture; 6 - Advent of renewable energies; 7 - From the nuclear twilight to the renewable dawn; 8 - Costs and benefits of the energy transition; 9 - The 'true value' of energy; 10 - From the status time to the action one. A series of 26 graphs summarizes the Negawatt approach. (J.S.)

    This note focuses of the major challenges for the French energy sector within a context of continuous cost increase, and outlines the central role of Europe to face the energy challenges. The authors state proposals under three main themes: a better management of energy consumption, a support to the emergence of new competitive industrial sectors without weakening the existing ones, and make the Europe of energy progress. The authors address the challenge of energy cost increase (a traditionally efficient French energy mix but with costs to increase in the future, a weak energy performance, a financial and regulatory framework not favourable to investments and innovation), discuss the European energy policy which, according to them, lacks ambition (a policy unbalanced by the prevalence of the climate issue, a national independence in contradiction with increasing interdependencies) and then make their proposals

    This note examines the major challenges faced by the energy sector in France in a context of continuous cost increase, of lack of domestic production, of high public expenses for the development of renewable energies, of low energy performance, of financial and regulatory framework which does not favour investments. It also highlights the central role of Europe to face these challenges although the European energy policy still lacks ambition, and is still dominated by the climate issue. It formulates a set of propositions about three main axes: a better management of energy consumption, a promotion of new emerging competitive industrial sectors without weakening the sectors of excellence France possesses in the field of energy, and to make the Europe of energy progress

  5. Struggle over energy transition in Berlin: How do grassroots initiatives affect local energy policy-making?

    International Nuclear Information System (INIS)

    Blanchet, Thomas

    2015-01-01

    This paper examines the growing role of grassroots initiatives in the governance of urban energy systems. In recent years, research has increasingly underlined the potential for sustainable innovation of community-led bottom-up actions but has at the same time underestimated their potential impact on the governance of energy systems. Based on a strategic action field framework (SAF), this paper analyses the conflicts over the remunicipalisation of Berlin's electricity grid and investigates the creation and strategic development of two grassroots initiatives as well as their interaction with the local government and the established grid operator. We argue that grassroots initiatives have an important impact on the local energy system, not just through their influence on the implementation of local energy policy but above all by their framing of a specific vision of a local energy transition. The paper discusses the scope and limits of such initiatives in an urban context. - Highlights: • Grassroots initiatives as actors with countervailing power in local energy policy. • They increase citizens' awareness and impact the action of the local government. • Grids as objects of struggle between competing visions of energy transition. • Urban context is both a resource and a constraint for grassroots initiatives action

    If there is one project today which carries a positive vision for Europe, it is definitely the energy transition. Energy is the foundation of our nations' power and is a key element in our daily lives. If Europe's architects are preparing a democratic, innovative, economically viable and socially fair Energy Union, it will contribute to a Europe that serves its citizens and paves the way for the rest of the world. If we fail in this project, the architects will have to give way to the fire-fighters, who will exhaust themselves putting out the fires caused by our past mistakes: climate refugees, dependence on Russia and Saudi Arabia, worsened energy poverty, the bankruptcy of energy suppliers who failed to adapt their strategy. The Energy Union, which we have been championing since 2010 and which is currently fully supported by President Juncker, is an ambitious project which can already be bolstered by the successes achieved by the European Union. The USA's withdrawal from the Paris Agreement further strengthens European leadership and enables us to attract innovators and investors who understand the opportunity created by the energy transition. This Report clearly sets out four objectives which could contribute to the success of the Energy Union, and in turn restore trust between Europe and Europeans. - Firstly, democracy must be at the heart of the Energy Union's governance. This involves mechanisms for more direct participation of citizens, local elected representatives and civil society in the major choices which shape national and European energy strategies. - Secondly, Europe must implement a genuine innovation-driven industrial policy to make our companies the world leaders in clean energy. - Thirdly, public and private investment arbitrations must fully integrate the energy transition's objectives. - Fourthly, the Energy Union must serve a just and fair energy transition via a 'Social Pact for the Energy Transition' which strives to create jobs for our

    This document presents the different steps of the decision support process for elected representatives and technicians to implement policies and actions for energy transition. It first addresses issues related to town planning where several contextual aspects must be taken into account (energy offer, energy demand, social values and individual abilities, governance level). It highlights different development options related to the development of local renewable energies, the development of energy-saving practices for households and firms, and to a contribution to energy transition competitiveness. It indicates how town and local planning tools and documents can be used to develop and implement an energy transition strategy. Three steps are thus identified: to inform local actors about their leeway, to develop a territory project which fits into energy transition, and to translate the transition strategy into a town planning document

    The yearly environmental conference will hold on September 2013 to evaluate the negotiations led at the national and local levels for december 2012. The government will have then to decide of an energy programming bill which will be submitted to the Parliament at the beginning of the year 2014. 30 main propositions have emerged of the decentralised debates. One of them is the ecological taxation which raise the question of the gas oil and petrol taxation. The current environmental taxes are for almost three quarters of them taxes on energy consumptions and mainly on fossil energies. The Economic, Social and Environmental Council, gives his opinion on the way to find resources to ensure the ecological and energy transition while reducing the public deficit of the State. (O.M.)

  9. The Hydrogen Economy Making the Transition to the Third Industrial Revolution and a New Energy Era

    International Nuclear Information System (INIS)

    Jeremy Rifkin

    2006-01-01

    Jeremy Rifkin is the author of the international best seller, The Hydrogen Economy, which has been translated into fourteen languages. It is the most widely read book in the world on the future of renewable energy and the hydrogen economy. In his presentation on 'The Hydrogen Economy', Mr. Rifkin takes us on an eye-opening journey into the next great commercial era in history. He envisions the dawn of a new economy powered by hydrogen that will fundamentally change the nature of our market, political and social institutions, just as coal and steam power did at the beginning of the industrial age. Rifkin observes that we are fast approaching a critical watershed for the fossil-fuel era, with potentially dire consequences for industrial civilization. Experts had been saying that we had another forty or so years of cheap available crude oil left. Now, however, some of the world's leading petroleum geologists are suggesting that global oil production could peak and begin a steep decline much sooner, as early as the second decade of the 21. century. Non-OPEC oil producing countries are already nearing their peak production, leaving most of the remaining reserves in the politically unstable Middle East. Increasing tensions between Islam and the West are likely to further threaten our access to affordable oil. In desperation, the U.S. and other nations could turn to dirtier fossil-fuels, coal, tar sand, and heavy oil, which will only worsen global warming and imperil the earth's already beleaguered ecosystems. Looming oil shortages make industrial life vulnerable to massive disruptions and possibly even collapse. While the fossil-fuel era is entering its sunset century, a new energy regime is being born that has the potential to remake civilization along radical new lines, according to Rifkin. Hydrogen is the most basic and ubiquitous element in the universe. It is the stuff of the stars and of our sun and, when properly harnessed, it is the 'forever fuel'. It never runs

    Defeuilley, Christophe

    2014-01-01

    In a first part, the author proposes an analysis of energy transition and of its consequences on the competitive environment. He recalls the main characteristics of energy transition and more particularly focuses on two aspects: the development of renewable energies and the management of demand. Thus, the author discusses the following issues: the relationship between the struggle against climate change and the low carbon economy, the development of renewable energies, the evolution and main actors of photovoltaic array and of wind turbine production, the distribution of photovoltaic and wind energy installed production among countries, and some key figures about the main renewable energy operators in Europe. He discusses how to manage consumptions, and operations performed. In a second part, the author addresses the impact of the German energy transition (Energiewende) on the business models of the main German energy operators (RWE and E.On). He recalls and comments the objective of this energy policy, presents the German electric and gas sector, comments the evolution of the electric utilities since 1998, more presently presents and discusses the activities of RWE and E.On, the evolution of their main financial indicators, and the levels of installed power with respect of energy sources

    2014-01-01

    After having recalled the main issues and stakes addressed by the French national debate on energy transition (strategic stakes, priority to a reduction of French energy consumption, options for the evolution of the French energy mix), the author comments the possible evolution of energy prices and of the energy taxing policy (evolution of oil prices, carbon price). In a second part, the author addresses the issue of financing of building and housing renovation. He shows that this operation cannot be only based on financial markets which are not efficient. This means that a public intervention is required, and different solutions are then possible. Some of them seem difficult to implement (creation of money by the central Bank, creation of a public bank which could lend money to private actors), and some others need to be further examined (creation of a financing company for energy transition, use of national savings, simplified circuits for a financing of local projects by local savings, and so on)

    In the long term, the sector coupling will convert other areas of consumption such as heat and transport to purely renewable energy sources. A model-based analysis of system costs across all stages of the value chain shows that the existing gas infrastructure in particular can make an important contribution to achieving a comprehensive energy turnaround at low cost. Preserving the gas networks in connection with the use of green gas as a further end energy carrier in addition to electricity leads to significantly lower overall costs than a comprehensive electrification of all end applications. This can also help overcome acceptance problems. [German] Mit der Sektorkopplung werden langfristig weitere Verbrauchsbereiche wie Waerme und Verkehr auf rein erneuerbare Energiequellen umgestellt. Eine modellgestuetzte Analyse der Systemkosten ueber alle Wertschoepfungsstufen hinweg zeigt, dass insbesondere die vorhandene Gasinfrastruktur einen wichtigen Beitrag leisten kann, eine umfassende Energiewende kostenguenstig zu erreichen. Ein Erhalt der Gasnetze in Verbindung mit der Nutzung von Gruenem Gas als weiterem Endenergietraeger neben Strom fuehrt zu deutlich niedrigeren Gesamtkosten als eine umfassende Elektrifizierung aller Endanwendungen. Zudem kann dies helfen, Akzeptanzprobleme zu ueberwinden.

    1991-01-01

    The author stresses the need for greater public participation, in particular, by organized labour in the role of organizer-coordinator, in the creation and implementation of local and regional clean energy-environmental protection programs. These would conform to innovative national strategies which would adapt the traditional short-sighted economic growth-energy use models still used by many industrialized countries, to current global requirements - that of harmonized global development and environmental protection to satisfy present needs without compromising the capacity of future generations, of developing, as well as, developed countries, to satisfy their own needs. With reference energy policies of Italy, heavily dependent on oil and gas imports, the author points out the strategic importance and technical-economic feasibility of energy conservation. He then makes suggestions on how to overcome past failures, due primarily to excessive bureaucracy and scarce investment, in the realization of effective energy conservation programs

  18. Energy systems in transition

    International Nuclear Information System (INIS)

    Haefele, W.

    1989-01-01

    The principal point of the author was to discuss energy systems (ES) in transition, transition addresses the next 10-25 years, and strategy of the transition. He considers different scenarios of future development of ES. Further he presents considerations elaborated during the last years on the concept of novel horizontally integrated ES which gives promise to be at least an approximation to the desired object of no emissions. The main ideas of the concept are: to decompose and thereby clean all the primary inputs before they are brought to combustion; to develop a network combining all the primary inputs to an integrated supply structure of high absorption, buffer, and storage capacity that resembles in some way the supply and utility functions of the well established electric grid but completes it at best on the basis of mass flows; to achieve a high flexibility in supplying the final energy. The author considers the long run perspective of hydrogen, solar, and nuclear energy with respect to alternative energy sources. 6 refs, 24 figs

    International Nuclear Information System (INIS)

    2014-07-01

    By presenting examples and experiments implemented in France, this publication illustrates the various ways to translate the objectives of energy transition into practical actions. A first part addresses the building sector and shows how to better renovate buildings: exemplary rehabilitations, techniques of construction to decrease energy consumption and equipment to control it, insulation by vegetal fibres, control of consumption decrease. The second part addresses the development of renewable energies: a heat network for household heating, innovative use of biogas, production of hot water by using solar energy, a waste incineration plant, heating by using waste waters. The third part addresses the promotion of circular economy: a recycling project, an optics-based glass sorting system, the commitment of Parisian restaurateurs for waste valorisation, a plant for waste sorting and valorisation

    After a synthesis which addresses and discusses the climate context and challenge, the importance and complexity of the energy issue within this context, the European commitment on these issues (energy efficiency, energy saving, greenhouse gas emissions), and the content and objectives of the French bill project on energy transition, this report outlines the need of an as quick as possible implementation of energy transition to cope with the climate emergency, and that new international constraints are also advocating for a transition towards a new energy model. It shows that the French bill project fully forms part of the European approach, and proposes additional measures

    2014-01-01

    While recalling the five main objectives of the French bill project for energy transition, the author proposes some critical reflections. He notices that economic, political and financial means to reach the expected decrease of energy consumption are not sufficient. He notably comments the content of the various retained scenarios, discusses and explains the fact that there will always be a gap between the expected optimal energy efficiency and the obtained results: economic actors are not ready to make the required investments, France lacks of a culture of territorial energy governance, and a way of paying the produced carbon emissions is missing. He discusses the introduction of a carbon tax. He states that the Efficiency scenario seems difficult to be reached and briefly discusses the associated consequences. He finally outlines that the nuclear issue is not clearly addressed, either in the Ademe's scenario or by the bill project

    2015-01-01

    The way to an energy transition will be reached with an integration of renewable energies in our energy mix. This development includes a legal transition because the current legal context that applies to green energies is not efficient and does not contribute to this emergency. Changing the legal frame becomes a necessity and particularly the way these energies are governed, planned and supported. It's also important that administrative procedures that regulate the implantation of energies production system are set. At last, this legal transition will have to conciliate imperatives linked to the development of renewable energies with those governing the protection of surroundings, all aiming to a sustainable development.

    International Nuclear Information System (INIS)

    Combe, Matthieu; Thouverez, Pierre

    2016-06-01

    As French energy policy is now defined for energy transition, the contributions of this publication discuss implemented measures, what new laws will change, and what will be the consequences for industry. A first set of articles thus comments evolutions related to the implementation of energy transition in the building sector, how energy transition wants to get rid of wastage, how energy transition will impact the transport sector (public transports, car-pool and car sharing, bicycle, retail sector, airfields), and outline that President Hollande has fulfilled (nearly) all his commitments. The next article comments changes and critics made by the French constitutional Council on the law for energy transition. The next set of articles comments the results of an ADEME's study on bicycle kilometre allowance, discusses the issue of energy safety, and comments statements made by candidates to the French President election of 2012 on nuclear energy after the Fukushima accident

    The economic ascent of China and India demonstrates how the model of economic development based on fossil fuels has reached its limits. Between them these two Asian countries have a population of more than 2.6 inhabitants, whose per capita energy consumption is still far below that in industrial countries. Given the low standard of living still prevailing among most of their population it is understandable that these emerging countries object to being told how they should develop. At the same time, however, they are increasingly developing an own interest in limiting their emissions and participating in global responsibility. And they expect the countries of the industrial world to provide them with the latest in technology to enable them to achieve their goals.

  6. Smart Energy Systems and Energy Transition

    International Nuclear Information System (INIS)

    Duic, N.

    2016-01-01

    Transition to decarbonized energy systems is becoming more attractive with fall of investment costs of renewables and volatile prices and political insecurity of fossil fuels. Improving energy efficiency, especially of buildings and transport, is important, but due to long life of buildings, it will be a slow way of decarbonization. The renewable energy resources are bountiful, especially wind and solar, while integrating them into current energy systems is proving to be a challenge. Solar has reached grid parity making it cheapest electricity source for retail customers in most of the World, creating new prosumer markets. It has started to reach cost parity in sunny countries, and soon solar energy will be cheapest everywhere. The limit of cheap and easy integration for wind is around 20% of yearly electricity generation, while a combined wind and solar may reach 30%. Going any further asks for implementation of completely free energy markets (involving day ahead, intraday and various reserve and ancillary services markets), demand response, coupling of wholesale and retail energy prices, and it involves integration between electricity, heat, water and transport systems. The cheapest and simplest way of increasing further the penetration of renewables is integrating power and heating/cooling systems through the use of district heating and cooling (which may be centrally controlled and may have significant heat storage capacity), since power to heat technologies are excellent for demand response. District cooling is of particular importance to historic cities that want to remove split systems from their facades. In countries with low heat demand water supply system may be used to increase the penetration of renewables, by using water at higher potential energy as storage media, or in dry climates desalination and stored water may be used for those purposes, and reversible hydro may be used as balancing technology. Electrification of personal car transport allows

    In October 2014, the International Energy Agency presented its first in depth report 'Morocco 2014 Energy Policy Review' of Morocco's energy policy, an evaluation and recommendations, with as reference the shared goals of the Agency. The accent was placed on renewable energies energy efficiency and climate change. The 'Moroccan way' of energy transition merits the attention of energy economists and of the negotiators involved in COP21. (authors)

    2008-05-01

    The transition to a global low-carbon energy sector is on the agenda of policymakers in the Netherlands, Europe and world-wide. However, the way in which the international political discussion takes place makes it far from clear that such a transition will indeed take place. Conflicts of interest between climate concerns, energy security, access to energy and profits made from fossil fuels should be analysed more properly and taken into account in international energy and climate negotiations in order to prevent that an energy crisis will be the only way forward towards a low-carbon energy sector.

    In today's business environment, control of energy cost is a major challenge for businesses, institutions, and governmental agencies. New technologies are available to reduce energy costs through cogeneration, cheaper fuels, or other means. Often it is not possible for a Plant Owner to undertake such a project, regardless of how desirable it may be. The authors of this paper show that by applying the principles of Project Structuring and developing a comprehensive project team, the desired reduction in energy costs can be achieved. Various examples are cited, and guidelines are given for an Owner to use

  11. Rate-making in economies in transition

    1996-01-01

    Eastern European economies in transition have unique needs which may be best served by considering how other economies around the world are making the transition to market-based economies. In particular, the recent Mexican experience may provide some lessons learned. Mexico has recently established for the first time a regulatory body with the power to regulate natural gas in certain ways. This paper outlines how the Mexican experience may be an appropriate jumping-off point for Eastern European economies in transition as they develop their own regulatory structure and rate-making. The paper concludes with an update on the recent experience in the U.S. to push the development of a market economy for natural gas further than it ever has before

    This publication by a think tank specialised in social and solidarity economy first outlines that energy transition means a transition from the present energy model to a new model based on three pillars: a drastic reduction of energy consumption through sobriety (energy saving, struggle against wastage), an improvement of energy efficiency, and an energy mix based on renewable and sustainable resources. A first part proposes a discussion of what 'citizen' energy transition can be: general framework of energy transition, pioneering examples in Europe, citizen empowerment, importance of a decentralised model which is anchored in territories, general interest as a priority. Each of these issues and aspects is illustrated by examples. Then, as this evolution towards a citizen-based model requires a change of scale, the authors discuss how to involve public authorities and to adapt regulation, how to develop financing tools, how to support the emergence and development of projects, and how to be part of international dynamics. The author then discuss what their think tank can do to accelerate energy transition. Proposals made in the different chapters are then summarized

    As a new policy for energy transition has just been adopted, several questions emerge about the best way to reduce CO 2 emissions, about policies which enable this reduction, and about their costs and opportunities. This note discusses the contribution macro-economic models may have in this respect, notably in the definition of policies which trigger behaviour changes, and those which support energy transition. The authors first discuss the stakes of the assessment of energy transition, and then describe macro-economic models which can be used for such an assessment, give and comment some results of simulations performed for France by using four of these models (Mesange, Numesis, ThreeME, and Imaclim-R France). The authors finally draw lessons about the way to use these models and to interpret their results within the frame of energy transition

  14. Hydrogen in energy transition

    International Nuclear Information System (INIS)

    2016-02-01

    This publication proposes a rather brief overview of challenges related to the use of hydrogen as an energy vector in the fields of transports and of energy storage to valorise renewable energies. Processes (steam reforming of natural gas or bio-gas, alkaline or membrane electrolysis, biological production), installation types (centralised or decentralised), raw materials and/or energy (natural gas, water, bio-gas, electricity, light), and their respective industrial maturity are indicated. The role of hydrogen to de-carbonate different types of transports is described (complementary energy for internal combustion as well as electrical vehicles) as well as its role in the valorisation and integration of renewable energies. The main challenges faced by the hydrogen sector are identified and discussed, and actions undertaken by the ADEME are indicated

    A plentiful, benign supply of energy is essential for a high standard of living. The current temporary oil surplus will soon be exhausted. Because of air pollution and the possible climatic changes which may be caused by increasing carbon dioxide in the atmosphere, fossil fuel combustion should be reduced. Oil and coal extraction also damage the environment. Fission nuclear energy has problems, fusion research lacks research funds. Renewable energy systems have not shown much promise for large-scale use. New energy systems must be developed and implemented. A system with fusion as the primary source and hydrogen (from the electrolysis of water) as the storage and distribution medium, is suggested as a potential system. (U.K.)

    Turmoil in macro-energy is occurring along with institutional changes that the French do not always unanimously follow. Habituated to the French public service model, which has maintained a fair level of prices and a constant supply of energy insofar as possible, the French are discovering a complex system that hinges ever more on services rather than prices: the culture of competition, complementarity and service. We must learn to sell and not just produce, to accept newcomers and become flexible. (author)

    Written by a representative of Air Liquide with the help of a free lance journalist, this book proposes an overview of the technological developments for the use of hydrogen as a clean energy with its ability to store primary energy (notably that produced by renewable sources), and its capacity of energy restitution in combination with a fuel cell with many different applications (notably mobility-related applications). The authors outline that these developments are very important in a context of energy transition. They also outline what is left to be done, notably economically and financially, for hydrogen to play its role in the energy revolution which is now under way

    Mills, Bradford; Schleich, Joachim

    2014-01-01

    New energy efficient lighting technologies can significantly reduce household electricity consumption, but adoption has been slow. A unique dataset of German households is used in this paper to examine the factors associated with the replacement of old incandescent lamps (ILs) with new energy efficient compact fluorescent lamps (CFLs) and light emitting diodes (LEDs). The ‘rebound’ effect of increased lamp luminosity in the transition to energy efficient bulbs is analyzed jointly with the replacement decision to account for household self-selection in bulb-type choice. Results indicate that the EU ban on ILs accelerated the pace of transition to CFLs and LEDs, while storage of bulbs significantly dampened the speed of the transition. Higher lighting needs and bulb attributes like energy efficiency, environmental friendliness, and durability spur IL replacement with CFLs or LEDs. Electricity gains from new energy efficient lighting are mitigated by 23% and 47% increases in luminosity for CFL and LED replacements, respectively. Model results suggest that taking the replacement bulb from storage and higher levels of education dampen the magnitude of these luminosity rebounds in IL to CFL transitions. - Highlights: • EU ban on ILs has fostered transitions to energy efficient lighting • Energy efficient, environmentally friendly, and durable lighting preferences make CFL and LED transitions more likely • Indicators of greater lighting needs are associated with higher propensities to replace ILs with CFLs and LEDs • For residential lighting, the rebound effect manifests itself through increases in luminosity • In IL to CLF transitions luminosity increases are lower with higher levels of education

    The author criticizes some aspects of the content of the French policy for energy transition. He states that the objective of reduction of greenhouse emissions is unreachable and moreover useless when China keeps on opening new coal-fired power stations. He states that temperatures do not increase any longer and that it is not sure that CO 2 emissions are responsible for past increases. He outlines that the power of wind turbines is only a quarter of their theoretical one, that replacing nuclear energy by wind energy would require the installation of 33.000 wind turbines. He states that objectives of energy saving are not credible, and that the energy mix predictions are fuzzy. He outlines contradictions about the nuclear power station life duration, states that the installation of 210 wind turbines per district would devastate the French landscape

  9. Three laws of energy transitions

    International Nuclear Information System (INIS)

    Bashmakov, Igor

    2007-01-01

    The paper formulates and explores a hypothesis on three general energy transition laws: the law of stable long-term energy costs to income ratio; the law of improving energy quality; and the law of growing energy productivity. These laws are essential for shaping long-term projections and checking for their consistency. All three are rooted in amazingly stable in time and universal across countries energy costs to income ratios. Limited energy purchasing power sets up thresholds, which, if exceeded, bring asymmetry to energy demand to price elasticity. The author believes, that the theoretical postulate on the substantial substitution among production factors, which is used in the production functions theory, may be incorrect. In reality, innovations mainly lead to the substitution of a low-quality production factor with the same yet of a better-quality. Improving energy quality with stable costs to income ratio is accompanied by growing energy productivity. Energy costs to income thresholds are indicators allowing for better projections of oil prices

    Chevalier, Jean-Marie; Cruciani, Michel; Geoffron, Patrice

    2013-01-01

    In this book, the authors propose an overview of assets and weaknesses of the French energy model, i.e. expertise and a unique energy patrimony on the one side, and a too strong dependence on hydrocarbons, an insufficient share of renewable energies, and prices which do not reflect the market reality on the other side. While addressing currently debated issues, the authors aim at proposing some clues and answers to different questions related to the interdiction of shale gas, to the role of nuclear energies in front of climate change, to the cost of development of renewable energies. They also discuss how to make the French energy system more efficient and to struggle against growing energy poverty

  11. Toward an energy transition period?

    International Nuclear Information System (INIS)

    Raineau, L.

    2011-01-01

    Energy is often only perceived in a very strict technical sense. This is may be the reason why renewable energies are frequently apprehend as mere substitutes for fossil energy, especially when they are centrally exploited, as in central solar or wind power stations. They are therefore supposed to replace this polluting energy within an unchanged technical and social context. Their very slight ability to meet this objective is related to this unrealistic challenge. Indeed, renewable energies demand new technical, political, economic and social systems, radically different from those operating with fossil and nuclear energies. To be effective and meaningful, they need new institutional framework, which would give a true decision-making power to citizen, allow a real decentralization and a local economy in the field of energy. Therefore, the main innovation these energies requires (and allows) is not technological, but political, economic and institutional. Here is the main challenge for these new, and in the mean time traditional, energies in our modern society. Mostly because it changes our relationship with Nature, renewable energies open new collective representations of environmental and energy problems facing nowadays society. We will at last illustrate our argument with the example of those ecological neighborhoods (or 'eco-villages') that are now developing in a growing number of cities all over the world. (author)

  12. Energy-urban transition: The Mexican case

    Paez, Armando

    2010-01-01

    In this paper I present a study regarding the institutional conditions of Mexican cities based on a post-petroleum urban model that considers transport, architecture, urban planning and land use, renewable energy sources, energy saving and efficiency, and urban metabolism issues. The model was constructed with recommendations of authors and organizations that have analysed the energy dimension of cities under an energy-availability, environmental or petroleum-independent view. To make the study I sent a questionnaire to some local governments of all the country. The information indicates that Mexican cities do not have institutional conditions to manage the urban-energy transition that signify the end of cheap oil and the peak of world oil production.

    Duchemin, Bruno; Genest, Sebastien

    2013-01-01

    Within the European framework, France has committed to a 20% reduction of its GHG emission by 2020 compared with 1990, and reaching the 'factor 4' by 2050. The 2005 POPE Act (the French Energy Policy Guidance Act) makes climate change a priority of the energy policy, setting out a 3% yearly reduction of our country's GHG emissions. This means combining energy efficiency and restraint, as is highlighted by the first chapter of the 'energy transition road-map'. Energy is a major component of transport. Designing its transition requires us to question the very organisation of our society: materials and their usage, the means of transport to favour and the infrastructures to implement, costs for competitiveness, the organisation of work and commuting... At a global scale, needs for mobility are increasing, as is the urgent need to deal with environmental problems. There are huge emerging markets for public transport, increasingly efficient and smart cars, information and transmission networks, infrastructures, the organisation of transport... However, France has all the assets to become a world leader in carbon-free transport. Succeeding in this change means organising the service to meet the needs of all, people, businesses, transport operators and industry, starting this transition right away. Policies must clearly define objectives and the means of achieving them through coordinated actions within a long term approach. The ESEC formulates a set of proposals in this direction

  14. Accelerating the transition to sustainable energy systems

    International Nuclear Information System (INIS)

    Jefferson, Michael

    2008-01-01

    The slow pace of transition to sustainable energy systems is the result of several factors running in parallel. The starting points are very low. Even 30% per annum increases in rated capacity (for wind energy or solar PV, for example) take many years to make a big impact at the global level. Policy initiatives are for the most part ineffectual in relation to the urgency and scale of what is required, and often fail to address the fundamental causes of this slow progress. This reflects a 'top-down' approach-often accompanied by unrealistic targets and simultaneously undermined by a lack of consistency across policies, which reflect a 'utopian social engineering mentality', made worse because: 'The Planner's response to failure of previous interventions (is) to do more intensive and comprehensive interventions' as William Easterly has put it. In short, there is little or no accountability. This approach has failed to harness the sympathy, imagination, self-interest, or sound options of energy users-although it may attract developers, including those not hitherto noted for renewable energy projects or environmental concern. Targets are usually too short term and clearly unrealistic, especially where fossil fuel use is rising very rapidly, and renewable energy use expands modestly. Government subsidies for traditional energy forms continue. Insufficient attention is paid to what individuals might achieve in energy efficiency and renewable energy terms if permitted to have, or retain (in industrialized countries, where the burden of taxation is often inhibiting), the wherewithal to make the necessary investments. Subsidy systems often promote renewable energy schemes that are misdirected and buoyed up by grossly exaggerated claims. One or two mature renewable energy technologies are pushed nationally with insufficient regard for their costs, contribution to electricity generation, transportation fuels' needs, or carbon emission avoidance. Investors are rewarded

    Written by several EDF R and D engineers, this book aims at presenting an overview of knowledge and know-how of EDF R and D in the field of energy storage, and at presenting the different technologies and their application to electric power systems. After a description of the context related to a necessary energy transition, the authors present the numerous storage technologies. They distinguish direct storage of power (pumped storage water stations, compressed air energy storage, flywheels, the various electrochemical batteries, metal-air batteries, redox flow batteries, superconductors), thermal storage (power to heat, heat to power) and hydrogen storage (storage under different forms), and propose an overview of the situation of standardisation of storage technologies. In the next part, they give an overview of the main services provided by storage to the electric power system: production optimisation, frequency adjustment, grid constraint resolution, local smoothing of PV and wind production, supply continuity. The last part discusses perspectives regarding the role of tomorrow's storage in the field of electrical mobility, for emerging markets, and with respect to different scenarios

  17. Nuclear energy in transition countries

    International Nuclear Information System (INIS)

    Knapp, V.

    2000-01-01

    Transition countries, respectively the countries that have in the year's 89/90 broken with the communist political and economy system are passing through difficult years. From their traditional markets within the closely interconnected socialist economy system, which has disintegrated, they have to reorient themselves to new, often saturated and sophisticated markets. To integrate into Europe as equal partners, rather then remain poor relatives, they must reduce this development gap in a reasonable time, not longer than 15 years. Slower pace would not give acceptable perspective to their young people and they would look for it elsewhere, thereby reducing creative forces for progress. Examples of economic development show that sustained growth of GDP is impossible without similar industrial growth, which, in turn, requires corresponding increase of energy use. In the same time these countries are the parts of densely populated European region and are subject to emission restriction of effluents with local or global effects. It is difficult to see how these countries could attain their development goals, whilst respecting their Kyoto obligations, without supplying increased energy demand from nuclear sources. (author)

  18. The energy transition in Sweden

    relative to GDP it is exactly equal to the average for Western Europe (EU 15). Regarding emissions of greenhouse gases, the country had the lowest carbon footprint in 2013 within the EU15, both in terms of GDP and per capita use. Moreover, while environmental taxes raise the price of gas for industry substantially, they do not affect fuel prices overly. Nor do taxes prevent electricity prices from being among the cheapest in Europe, both for industry and for households. The current situation seems to be excellent. As a result, Sweden's political leaders have chosen to keep its underlying foundations and to carry out only moderate changes. Thus, while stating their preference for renewable energy, the major political parties have found common ground to reduce tax pressures on nuclear power, since 2014. In June 2016, the Parliamentary majority and opposition parties signed an agreement to modernize Sweden's fleet of reactors, thus further demonstrating their sense of compromise. This solution is designed to limit the rise in electricity costs and to lengthen the period available for alternative energy sources to reach maturity. In addition, the agreement extends the provisions promoting renewable power, but it also emphasizes the importance of managing the demand for capacity as well as the efficient use of electricity, giving consumers of power an active role, be they industrial or domestic users. In short, Sweden seems to have taken measure of the difficulties faced by some European countries which are already engaged in the energy transition and is trying to avoid them. Its political actors have been careful not to adopt excessively restrictive short-term goals and are content with general guidelines: they are betting on innovation to move forward. In this regard, Sweden has a major advantage, alongside the efforts made for several years, favouring research and development in a very structured way. The recent agreement consolidates these efforts. (author)

    Illustrated by many graphs, figures, maps and tables, this Power Point document presents the main issues related to energy and concerning citizens and consumers, proposes a definition of energy transition, identifies the main levers for energy transition and the main questions raised by the objectives of energy transition: energy efficiency and sobriety, trajectory to reach the energy mix, choices related to renewable energies and to energy technologies, costs and financing, governance. Other challenges are outlined and discussed: governance, energy mix, industrial policy, competitiveness and jobs, energy management, household energy consumption and poverty, climate and energy, supply safety and trade balance, health and environmental impacts, price, cost, taxing, financing and macro-economic consistency. For each of these challenges, facts are highlighted and problems to be solved are identified

  20. An Institutional Approach to Understanding Energy Transitions

    Science.gov (United States)

    Koster, Auriane Magdalena

    Energy is a central concern of sustainability because how we produce and consume energy affects society, economy, and the environment. Sustainability scientists are interested in energy transitions away from fossil fuels because they are nonrenewable, increasingly expensive, have adverse health effects, and may be the main driver of climate change. They see an opportunity for developing countries to avoid the negative consequences fossil-fuel-based energy systems, and also to increase resilience, by leap-frogging-over the centralized energy grid systems that dominate the developed world. Energy transitions pose both challenges and opportunities. Obstacles to transitions include 1) an existing, centralized, complex energy-grid system, whose function is invisible to most users, 2) coordination and collective-action problems that are path dependent, and 3) difficulty in scaling up RE technologies. Because energy transitions rely on technological and social innovations, I am interested in how institutional factors can be leveraged to surmount these obstacles. The overarching question that underlies my research is: What constellation of institutional, biophysical, and social factors are essential for an energy transition? My objective is to derive a set of "design principles," that I term institutional drivers, for energy transitions analogous to Ostrom's institutional design principles. My dissertation research will analyze energy transitions using two approaches: applying the Institutional Analysis and Development Framework and a comparative case study analysis comprised of both primary and secondary sources. This dissertation includes: 1) an analysis of the world's energy portfolio; 2) a case study analysis of five countries; 3) a description of the institutional factors likely to promote a transition to renewable-energy use; and 4) an in-depth case study of Thailand's progress in replacing nonrenewable energy sources with renewable energy sources.

    Three ''unconventional'' energy technologies - geothermal, solar and fusion - looked upon in the United States as possessing significant potential for the large scale production of energy. Both fusion and solar energy promise virtually inexhaustible supplies in the long term while geothermal resources offer a relatively near term prospect for more modest, but still significant, energy contributions. Realizing energy production from any of these technologies will require: (1) a great deal of scientific information and/or engineering development; (2) a significant effort to achieve and insure attractive economics; and (3) the development of adequate industrial capacity and technological infrastructure. Here the status of the United States Energy Research and Development Administration's technology development programs in geothermal, solar and fusion energy systems is reviewed. Recent advances in overcoming significant technological barriers are discussed and future directions are described. Special needs and unique opportunities for contributions to each technology are also set forth.

The next part comments OPECST activities related to energy transition, evokes some reports published on different topics: the future of the nuclear sector, the perspectives of non conventional hydrocarbons, the possibilities of the use of hydrogen for energy storage. Several aspects are notably addressed: the technical conditions to be met for a successful energy transition, the role of nuclear energy in energy transition, the extension of nuclear reactor service lifetime, the opinion of the OPECST on some prospective scenarios (ADEME and Negawatt). The improvement of buildings thermal insulation is commented as a major element in energy transition, but the complexity of regulations and problems for investors are outlined, as well as the cost of renovation for households

  5. Carbon pricing. A lever for energy transition

    International Nuclear Information System (INIS)

    2016-01-01

    The international community has set itself the target of limiting the global temperature rise to 2 deg. C. In today's world, the challenge is to invent new ways of manufacturing goods, producing food, travelling and keeping ourselves warm, without emitting more greenhouse gases (GHG) into the atmosphere than what we are technically able to remove from it. Climate action can be considered as an insurance for our societies against unacceptable costs generated by the risk of increasingly frequent climate-triggered natural disasters, irreversible damage to ecosystems and mass population migrations. In addition to avoid climate damage there are many benefits of climate action, including greater energy autonomy, reduced atmospheric pollution, which is harmful for human health, and the economic benefits of new green growth sectors. However, the efforts needed to make the transition to economies that emit fewer greenhouse gases must not be underestimated. This transition requires the mass redirection of investments into clean transport, renewable energy sources, building insulation and the development of agro-ecology, in a highly restricted financial and budgetary context. The economic and financial tools used for explicit or implicit carbon pricing give clear messages about the benefits of emitting less carbon, or alternatively the cost of greenhouse gas emissions for society. Consequently, they make it possible to accelerate the energy transition. 74 countries and over 1,000 businesses formed a coalition for carbon pricing during the United Nations Climate Summit in September 2014, held at the invitation of the UN Secretary-General. The goal of the coalition is to promote productive dialogue between public and private decision-makers concerning opportunities to extend carbon pricing policies. It has been officially launched on November 30, 2015, on the opening day of COP21. It has been officially launched on November 30, 2015, on the opening day of COP21. Members of the

    In the wake of the 2011 Fukushima nuclear disaster, the German authorities launched the country's energy transition, or Energiewende. With near unanimous support of Germany's citizens, it was seen as a society-wide project. The enthusiasm the Energiewende generated soon spread beyond the Rhine. Indeed, for many French people it became the model to follow. Replacing nuclear energy and fossil fuels with renewable energy sources that were local when possible, developing electric mobility and making progress towards a zero carbon economy were all virtuous goals. What's more, it seemed they could be attained over a relatively short period of time and at reasonable cost. Today, the Energiewende's future looks less bright. While Germany produces a third of its electricity from renewable energy, this comes at a high price. The cost of electricity for small consumers more than doubled between 2000 and 2013. At the same time, the country continues to rely on coal to produce a large share of its electricity and still has one of the highest levels of CO_2 per person in Europe. But Germany's population is divided about closing its coal-fired and lignite power plants, not to mention doing so would jeopardize its energy supply. Add to this the fact the massive development of intermittent renewable energy sources has made the German power grid unstable and has necessitated the construction of thousands of kilometers of high voltage lines amidst strong local opposition. Lastly, electrifying the transport sector could serve to compound the series of scandals that have hit the automotive industry. Against this backdrop, the coalition government formed following the September 2017 federal elections could very well lower the bar for the Energiewende. (author)

  12. Energy transitions research: Insights and cautionary tales

    International Nuclear Information System (INIS)

    Grubler, Arnulf

    2012-01-01

    This short essay first reviews the pioneers of energy transition research both in terms of data as well as theories. Three major insights that have emerged from this nascent research fields are summarized highlighting the importance of energy end-use and services, the lengthy process of transitions, as well as the patterns that characterize successful scale up of technologies and industries that drive historical energy transitions. The essay concludes with cautionary notes also derived from historical experience. In order to trigger a next energy transition policies and innovation efforts need to be persistent and continuous, aligned, as well as balanced. It is argued that current policy frameworks in place invariably do not meet these criteria and need to change in order to successfully trigger a next energy transition towards sustainability. - Highlights: ► Includes the first literature review of early energy transition research. ► Summarizes three major research findings from the literature. ► Reviews policy implications of recent case studies of energy technology innovation. ► Argues that current policy frameworks are deficient in view of above lessons.

  13. Germany: energy transition or revolution

    2013-01-01

    Germany has decided to phase out nuclear power by 2022 but it wants also to get rid of fossil energies by 2050. Those ambitious goals imply to be able to cut by half the demand for primary energy by 2050 which will be only possible if the need for building heating is cut by 80%, the constraint on transport is less important: one million of electrical vehicles will have to be on the road by 2020 and 3 millions 10 years later. In 2012 the production of electricity was made mainly from coal (44.7%), renewable energies (21.9%), nuclear energy (16%), natural gas (11.3%) and other energies (fuel...) (6.1%). Today the renewable energy sector is a major industrial sector in Germany, it represents about 382000 jobs directly or indirectly, it means more than the sector of conventional energies. (A.C.)

  14. Is the German energy transition sustainable?

    International Nuclear Information System (INIS)

    Beeker, Etienne; Godot, Clelia

    2012-09-01

    In 2011, Germany began a radical energy policy, or 'Energiewende', with the aim of completely abandoning nuclear power by 2022 and then achieving an 80-95% reduction in the country's greenhouse gas emissions by 2050. By this date, the country will therefore have to be producing its electricity almost completely without the use of gas, oil and coal, having replaced 80% of these sources with renewable energies. Germany is a rich country with one of the most competitive industries in the world. Its environmental commitments have been clearly stated and Energiewende, which is widely discussed throughout the country, has so far seen strong support from the population, despite the expected increases in the price of electricity which, however, is already almost twice as expensive as in France. Germany therefore seems to hold the winning cards required to successfully implement its energy transition. However, many difficulties need to be overcome if this energy policy is to succeed, such as the development of the national power grid, the cost and financing of the necessary investments, improved electricity storage techniques, the acceptability of the planned increases in the price of electricity or the financial difficulties experienced by solar panel manufacturers as a result of the sharp reduction in subsidies and competition from Asia. In addition, recent political dissent within the government regarding the measures implemented to achieve its stated goal has slowed down the federal decision-making process on this matter. Finally, Germany's decision is not without consequences for its European neighbours. It is upsetting and weakening the supply and demand balance of the European energy system and putting some operators in a difficult position. The eyes of all energy world observers are therefore riveted on the changes taking place in Germany, because they will have significant consequences for the entire European Union, and even beyond.

  15. The Greenpeace 2013 scenario for energy transition

    International Nuclear Information System (INIS)

    Cormier, Cyrille; Teske, Sven

    2013-01-01

    After a synthesis of the Greenpeace scenario for energy transition, this report presents the French current energy landscape: structure of the energy system, greenhouse gas emissions and nuclear risks, main social and economic challenges, and search for a political ambition (from the Grenelle de l'Environnement to the current debate on energy). Then, after having outlined that energy transition must be decided now, the report presents the scenario hypotheses: studies used to develop the scenario, macro-economic and technical-economic hypotheses. The scenario is then presented in terms of possible trajectory, of energy demand (global evolution per sector), of energy production (electricity, heat, mobility), and of CO 2 assessment and nuclear wastes. Scenarios are compared in social and economic terms, more particularly in terms of investments in electricity and heat production systems, of electricity production costs and electricity bill, of energy independence, and of jobs in the electricity and heat sectors

    Wood, straw, agricultural residues, organic wastes, biomass is everywhere you look. But the efficient use of this source of green electricity - the world's second largest renewable energy source - requires optimization of biomass collection and combustion processes. Biomass is back on the political agenda. In mid-June of this year, the French government gave this renewable energy a boost by selecting twenty-two projects to generate power and heat with biomass. The plants, to be commissioned by 2010, will be located in eleven different regions and will consume energy from organic plant matter. The power generated will be bought at a firm price of 128 euros per megawatt-hour. Most of the fuel will come from forest and paper industry waste, but straw and even grape pomace will be used in some cases. The plants will have a combined generating capacity of 300 MWh, raising France's installed biomass capacity to a total of 700 MWe. A drop of water in the ocean in the overall scheme of France's electricity. It is true that France has long neglected biomass. In 2004, electricity generated from biological resources represented a mere 1.74 TWhe in France, just 0.3% of its power consumption. This will rise to 0.6% once the new plants have come on line. The trend is the same in all of the EU's 27 member states, according to Eurostat, the statistical office of the European Communities: the amount of electricity generated from biomass (including biogas, municipal waste and wood) has practically doubled in six years, rising from 40 to 80 TWhe between 2000 and 2005. This is an improvement, but it still only represents 2.5% of the electricity supplied to Europeans. On a global scale, biomass contributes just 1% of total electric power generation. Yet biomass is an energy resource found all over the world, whether as agricultural waste, wood chips, or dried treatment plant sludge, to name but a few. Biomass power plants have managed to gain a foothold mainly in countries that produce

    The author describes gas as the less polluting fossil energy. He outlines that new gas fields have been discovered, notably non conventional gas fields. He notices that whatever conventional or not conventional, a gas field produces methane, and that there is therefore no difference for the end user. However, he notices that reserve assessments by the IAE are a matter of discussion, and that hydraulic fracturing has resulted in important environmental and human damages. Anyway, gas will be needed to face energy demand

  20. Energy networks - The data serving the energy transition

    International Nuclear Information System (INIS)

    2017-03-01

    The complementary aspects of the electricity and gas transport networks open new perspectives for the construction of a global energy system that is smarter and oriented to the integration of renewable energies. Moving beyond existing cooperative projects on the security of supply, GRTgaz and RTE intend to draw benefit from the digital revolution to build a response to the regional issues of energy, transport and climate. The Open Data platform provides energy production and consumption data on national and local levels. Use of these multi-energy and multi-operator data will facilitate the development of local authority energy policies and contribute strongly to innovation. It will also contribute to the efficiency of stakeholders in the energy system to engage in more pertinent activities with regions. This first data set is part of the ongoing transparency approach adopted by GRTgaz and RTE to provide better information to citizens, regional authorities and economic actors, for use in developing and assessing energy policies. GRTgaz and RTE already operate web sites (Open Data RTE, Open Data GRTgaz) and applications (GRTgaz+ and eCO2mix), which provide open access to key data concerning energy transport networks. The new energy network data platform will be enriched over time with data from other electricity and gas infrastructure operators. RTE joins the Jupiter 1000 project driven by GRTgaz. The Jupiter 1000 project located in Fos-sur-Mer (Bouches-du-Rhone) is designed to test the technical and economic viability of the Power to Gas concept. This consists in transforming surplus electrical energy from renewable sources into methane by combining hydrogen with CO 2 , for injection and storage in gas networks. RTE has joined the Jupiter 1000 project driven by GRTgaz and featuring seven other industrial partners, with several objectives: manage its needs for flexibility, develop the integration of renewable energy sources and make a valuable contribution to the

  1. User Innovators in the Smart Energy Transition

    DEFF Research Database (Denmark)

    Nyborg, Sophie; Borch, Kristian; Bentzen, Martin Mose

    Notions of "smart energy systems" are pervasive in discussions of a low carbon transition and much work is devoted to developing "smart energy technologies" and analyzing their economic potential. However, users, i.e. civil society receive only little attention and are mainly described as "energy...... consumers". The aim of this research project is to explore how civil society can get a more active role in the transition towards a low carbon energy system. Through qualitative case-study methods and scenario work, we explore the role of "energy users" for the innovative design and development of large...... technological systems. We ask whether the envisioned smart energy systems have potential to support more active innovation roles for the individuals using energy systems than what have been described by previous studies. Moreover, we discuss whether and how such roles allow for a democratic as well as socially...

    The history of cities is a history of energy transitions. In the medieval city heating and cooking occurred with wood and peat. The growth of the industrial city in the 19th century was built on coal and electricity. The sprawling metropolis of the 20th century was made possible by oil and gas. How will the city of the 21st century look after the next energy transition from fossil to renewable energy? This paper reports on the extension of an urban land-use transport interaction model to a model of the energy transition in the Ruhr Area, a five-million agglomeration in Germany. The paper presents the planned model extensions and how they are to be integrated into the model and shows first preliminary results.

    The authors consider the transition radiation arising when a charged particle crosses an interface between two nonabsorbing media. It is shown that energy balance is observed under these circumstances. The fulfillment of energy balance in transition radiation for nonabsorbing media is rigorously demonstrated. This allows one to find the energy of the transition radiation from the change in the energy of the intrinsic field of the charge and the work of forces for volume waves, which in a number of cases of complicated configurations may prove to be considerably simpler than a direct calculation of the radiation power. For surface waves, a calculation of the work of forces enables one to determine the radiation power directly

    This article presents the main issues addressed by the French law on energy transition for a green growth. Thus, it evokes its main objectives and how they can be reached (notably through a control of energy demand, a wider carbon share in taxes), gives an overview of measures related to building renovation, to the development of clean transports (priority to less polluting transport modes, energy efficiency and renewable energy in transports, reduction of greenhouse gas and pollutant emissions, plan for air quality), to the struggle against wastage and to the promotion of circular economy, to the promotion of renewable energies, to the reinforcement of nuclear safety and citizen information, to the simplification and clarification of procedures, to making citizens, enterprises and State able to act together (through governance tools, the steering of electricity production, energy transition in territories, specific measures for non-interconnected areas)

  6. Widening energy access in Africa: Towards energy transition

    International Nuclear Information System (INIS)

    Sokona, Youba; Mulugetta, Yacob; Gujba, Haruna

    2012-01-01

    The discussion to widen access to modern energy services has been influential in shaping some of the discussions on energy at the international level. The practice of widening modern energy services access to the poor in Africa is complex, and exacerbated by the dual nature of the energy system across Sub-Saharan Africa where traditional and modern energy systems and practices co-exist. This presents major challenges for policy makers who have to contend with a fragmented energy system, which requires the mobilisation of an array of actors at cross-sectoral levels in order to develop effective institutions and implement innovative policy frameworks. This paper further argues that, the ‘energy access’ discussion needs to take place in the context of energy transitions, giving due consideration to the productive sector as an important vehicle for change. As the link between energy and development is context specific, each African country needs to chart its own energy transition pathway into the future, and there are ample lessons that they can draw from previous energy transitions. - Highlights: ► Lack of access to modern energy services in Africa is an impediment to socio-economic development. ► Widening modern energy services access to the poor in Africa is complex. ► A broader approach to address the ‘energy access’ discourse is required. ► Each African country needs to chart its own energy transition pathway. ► Both fossil and renewable energy systems would be needed for a transition to modern energy sources.

    The stakes of embarking upon a Mediterranean Energy Transition is essential for countries from both shores of the Mediterranean, especially taking into account the increasing demographics (+105 million by 2040) and the fast growing energy demand in an increasingly constrained context both in terms of energy availability and environmental impacts of conventional energy sources uses. There is a huge, but yet untapped, potential for energy efficiency and renewable energy sources, especially in the South Mediterranean region. By improving energy efficiency and deploying renewables on a large scale, the Mediterranean region would reduce tensions on energy security for importing countries, improve opportunities for exporting ones and reduce energy costs and environmental damages for the whole region. Embarking on an energy transition path will also help improve social welfare in the region and contribute to job creation, among other positive externalities. OME regularly conducts prospective works to 2040, assessing the impact of prolonging current energy trends. Under this Business-As-Usual or so-called 'Conservative' Scenario the situation would evolve critically on all counts over the next 25 years: doubling of energy demand and tripling of electricity consumption, soaring infrastructure and import bills (+443 GW to be installed and doubling of the fossil-fuel imports) and a critical rise in carbon emissions (+45%). Such a scenario, based essentially on fossil fuels, would put further strain on the environment and exacerbate geopolitical tensions in the region. A change of energy trajectory is therefore necessary for all Mediterranean countries to help change current trends and to increase efforts promoting energy efficiency and renewable energies. In this context, MEDENER and OME, based on the 2030-2050 visions of ADEME and the prospective tools of OME, have decided to jointly investigate a Mediterranean Energy Transition Scenario, an ambitious scenario that

    In Europe, energy transition is already in full swing. In the power supply, wind and solar energy play an increasingly important role. The fluctuating feed-in of these often also decentral energy sources can lead to capacity problems at different network levels. Intelligent electrical networks, so called "smart grids", optimally optimize system capacities through ongoing coordination between producers. From a global point of view, the aim is to set a set of measures that meet the most important target parameters for the smart networks: maximum integration of renewable energy sources, maximum security of supply and an optimal functioning of the energy markets in an economically efficient manner.

    2012-01-01

    Energy efficiency represents a cost-effective and immediate strategy of a sustainable development. Due to substantial environmental and economic implications, a strong emphasis is put on the electrical energy requirements of machine tools for metalworking processes. The improvement of energy efficiency is however confronted with diverse barriers, which sustain an energy efficiency gap of unexploited potential. The deficiencies lie in the lack of information about the actual energy requirements of machine tools, a minimum energy reference to quantify improvement potential and the possible actions to improve the energy demand. Therefore, a comprehensive concept for energy performance management of machine tools is developed which guides the transition towards energy efficient machine tools. It is structured in four innovative concept modules, which are embedded into step-by-step workflow models. The capability of the performance management concept is demonstrated in an automotive manufacturing environment. The ...

    Bain-Thouverez, Justine; Romi, Raphael; Chautard, Thomas

    2016-07-01

    As the French law on energy transition reconfigures many parameters of implementation of public action, the authors propose a cross-referenced reading of this law, of the law for new organisation of territories (NOTRe) in its environmental dimension, and of the regulation which results from these legal standards, in order to have a better view on public action in terms of abilities, and of action and financial levers. In a first part, the author discuss the relationships of energy transition with State, regions, districts, EPCI (communal collaboration public body), communes, and public bodies. In the second part, they address the new levers for action, and finally address the financing of energy transition (financing funds, third-party financing companies)

    2015-01-01

    Influencing the demand for energy and modifying the means of production while introducing new uses are part of a quite complicated equation. Smart electricity grids are very important for solving this equation and indispensable for the energy transition. Since they deeply alter jobs in this sector, they are forcing industrialists to draw up a genuine strategy. ABB is convinced that a successful energy transition involves using three levers: the evolution of consumer behavior patterns; the regulatory and legal framework; and the deployment of technical solutions. As for the last, ABB can, owing to its strong experiences and skills, advise decision-makers about the changes necessary in existing networks so as to open the way for this transition toward a sustainable world

    International Nuclear Information System (INIS)

    Lee, S.Y.; Wang, J.M.

    1985-01-01

    It is well known that during the acceleration of hadrons in a storage ring, the beam always goes above the microwave instability threshold near the transition energy γ /SUB t/ . The reason is that the longitudinal revolution frequency spread of the beam which otherwise provides Landau damping vanishes at the transition energy. The amount of the beam dilution near the transition energy is determined by /tau/ /SUB th/ , the length of time when the beam stays unstable, and the growth rate of the instability. It is pointed out in this paper that /tau/ /SUB th/ is proportional to the fourth power of γ /SUB t/ , and thus the choice of a large γ /SUB t/ is not desirable from this point of view. An analysis is also given of the microwave instability induced beam dilution for the proposed Relativistic Heavy Ion Collider at BNL

    The energy transition is a response to the environmental and climate issues now facing our planet. It is also a source of growth and jobs, both very important during the current economic slowdown. Far from being a preoccupation of France alone, this transition toward green growth brings together a vast international movement bearing a new awareness by scientists, citizens and their representatives. Accordingly, changes in the 'energy model' are to be made through joint efforts and the reinforced role to be played by citizens and local authorities for the sake of the environment and well-being and with the ambition of addressing the new century's main environmental issues

    After having recalled the meaning of the concept of energy transition, and stated that this concept is a fuzzy one, this paper addresses the issue of the future of energy through the concept of Energy returned on Energy invested (EROI). It discusses this approach by outlining that energy is the initial driver of economy, and by showing that only hydroelectricity, coal, nuclear and wind energy have a sufficient return rate, and that shale gas is an energy source for the short and medium term. Then, based on data related to world energy resources and consumption, to electric power production from various sources, to pollution health impacts, to electricity prices for industries and for households, it discusses the sustainability of the energy mix regarding energy reserves, health issues, and economic issues. Some examples (Spain, Germany) illustrate economic problems faced by some renewable energies. Finally, the authors outline that, thanks to its nuclear policy, France is the western country which is the most committed in energy transition. Some proposals are made to support nuclear energy, to reduce the use of fossil energies, to launch an ambitious research policy (on energy storage, on photovoltaic energy, on CO 2 hydrogenation, on hydrogen as a fuel), in favour of energy mixes decided at national levels in Europe

    We studied the energy exchange dynamics across the low-to-high-confinement (L-H) transition in NSTX discharges using the gas-puff imaging (GPI) diagnostic. The investigation focused on the energy exchange between flows and turbulence to help clarify the mechanism of the L-H transition. We applied this study to three types of heating schemes, including a total of 17 shots from the NSTX 2010 campaign run. Results show that the edge fluctuation characteristics (fluctuation levels, radial and poloidal correlation lengths) measured using GPI do not vary just prior to the H-mode transition, but change after the transition. Using a velocimetry approach (orthogonal-dynamics programming), velocity fields of a 24× 30 cm GPI view during the L-H transition were obtained with good spatial (˜1 cm) and temporal (˜2.5 μs) resolutions. Analysis using these velocity fields shows that the production term is systematically negative just prior to the L-H transition, indicating a transfer from mean flows to turbulence, which is inconsistent with the predator-prey paradigm. Moreover, the inferred absolute value of the production term is two orders of magnitude too small to explain the observed rapid L-H transition. These discrepancies are further reinforced by consideration of the ratio between the kinetic energy in the mean flow to the thermal free energy, which is estimated to be much less than 1, suggesting again that the turbulence depletion mechanism may not play an important role in the transition to the H-mode. Although the Reynolds work therefore appears to be too small to directly deplete the turbulent free energy reservoir, order-of-magnitude analysis shows that the Reynolds stress may still make a non-negligible contribution to the observed poloidal flows.

    Since the beginning of the new millennium, the concept of “energy landscape” is being discussed by academia from the environmental design domain while more and more practitioners have been contributing to sustainable energy transition. Yet, there remains some ambiguity as to what exactly is meant

  20. Transition towards energy efficient machine tools

    Energy Technology Data Exchange (ETDEWEB)

    Zein, Andre [Technische Univ. Braunschweig (Germany). Inst. fuer Werkzeugmaschinen und Fertigungstechnik

    2012-07-01

    Provides unique data about industrial trends affecting the energy demand of machine tools. Presents a comprehensive methodology to assess the energy efficiency of machining processes. Contains an integrated management concept to implement energy performance measures into existing industrial systems. Includes an industrial case study with two exemplary applications. Energy efficiency represents a cost-effective and immediate strategy of a sustainable development. Due to substantial environmental and economic implications, a strong emphasis is put on the electrical energy requirements of machine tools for metalworking processes. The improvement of energy efficiency is however confronted with diverse barriers, which sustain an energy efficiency gap of unexploited potential. The deficiencies lie in the lack of information about the actual energy requirements of machine tools, a minimum energy reference to quantify improvement potential and the possible actions to improve the energy demand. Therefore, a comprehensive concept for energy performance management of machine tools is developed which guides the transition towards energy efficient machine tools. It is structured in four innovative concept modules, which are embedded into step-by-step workflow models. The capability of the performance management concept is demonstrated in an automotive manufacturing environment. The target audience primarily comprises researchers and practitioners challenged to enhance energy efficiency in manufacturing. The book may also be beneficial for graduate students who want to specialize in this field.

  1. The role of hydrocarbons in energy transition

    International Nuclear Information System (INIS)

    2015-11-01

    This publication presents some reflections and statements as well as data regarding the role of hydrocarbons in energy production and consumption, in order to better highlight the role hydrocarbons may have in energy transition. It outlines the still very important share of oil in primary and final energy, and more particularly in transports, and that, despite the development of other energies, an energy transition is always very slow. It discusses the perspectives for hydrocarbon reserves and production of oil and natural gas. It outlines that oil remains the most important energy for mobility, the benefits of conventional fuels, and that distribution infrastructures must be preserved and developed. It discusses the evolution of the economic situation of the refining activity (more particularly its margin). It outlines the high contribution of oil industry to economic activity and employment in France, discusses the French energy taxing policy and environmental taxing policy, discusses the issue of security of energy supply (with its different components: exploration-production, refining, logistics and depots, distribution and station network). It discusses the possible role shale hydrocarbons may have in the future. For each issue, the position and opinion of the UFIP (the French Union of oil industries) is stated. The second part of the document proposes a Power Point presentation with several figures and data on these issues

    2013-01-01

    Within the debate on energy transition, the Negawatt scenario predicts a strong decrease of final consumption and the end of the nuclear, whereas the Negatep scenario predicts a moderate decrease of consumption, more nuclear energy to face the challenges of low-carbon energy. Independently of the technical feasibility and social acceptance of these both opposite scenarios, this study proposes a comparative economic assessment for each expense and saving of these scenarios in different sectors (housing insulation, infrastructure works for transports, renewable heat, non-intermittent and intermittent energy, nuclear energy, biomass-based fuels, and fossil fuels). This comparison is based on two reference evolutions: a status quo (the energy situation remains the same) and 'business as usual' (growth continuity). Negawatt appears to be less expensive, but would imply a socially dangerous deterioration

  3. Energy transition and urban ecological inequalities

    2017-01-01

    This paper deals with social inequalities in the relationship to the environment, by looking at the capacity of actors to mobilize around renewable energy initiatives in the context of the energy transition. It is based on field surveys (qualitative and quantitative) on an urban scale, conducted between 2012 and 2015 in the metropolitan area of Strasbourg. We show that the emphasis on resident involvement masks the reality of rather prescriptive 'eco-innovations'; and that the differentiated relations of the inhabitants to the technical tools meant to materialize renewable energy reveal ecological inequalities that reinforce socio-economic division in the city

  4. Astrophysical relevance of γ transition energies

    The relevant γ energy range is explicitly identified where additional γ strength must be located to have an impact on astrophysically relevant reactions. It is shown that folding the energy dependences of the transmission coefficients and the level density leads to maximal contributions for γ energies of 2≤E γ ≤4 unless quantum selection rules allow isolated states to contribute. Under this condition, electric dipole transitions dominate. These findings allow us to more accurately judge the relevance of modifications of the γ strength for astrophysics

  5. Potential of forestry biomass for energy in economies in transition

    1995-01-01

    A rapid increase in the world's population, the gradual exhaustion of fossil fuels and serious ecological problems are making developed countries more attentive to the utilization of renewable energy sources, mainly biomass, which should form part of the global energy mix during the twenty-first century. The economies in transition have been experiencing a transformation of their political, economic and social systems and a modernization of their industry, including the energy industry. Energy supply in the transition economies is based on coal, oil, gas and nuclear power. Of the renewable sources, only hydroelectric power is utilized to any significant extent. The forest biomass resources of these economies are quantified in this paper. The economies in transition have a big potential for biomass from forestry and timber industry wastes and agricultural wastes that are not being utilized and could become a source of energy. So far, biomass is used as a source of energy in only small amounts in the wood and pulp industries and as fuelwood in forestry. The governments of some countries (the Czech Republic, Hungary and Slovakia) have energy plans through the year 2010 that aim to develop renewable energy sources. Economic, institutional, technical and other barriers to the development of renewable sources and their utilization are analysed in this paper and some remedies are proposed. In cooperation with countries such as Austria, Denmark, Sweden, Finland, the United States of America and others, which have achieved remarkable results in the utilization of biomass for energy, it would be possible for the transition economies to quickly develop the technological know-how needed to satisfy the demand for energy of approximately 350 million inhabitants.

    2010-09-15

    Tokyo is a Megalopolis with 40 million+ population. It has an energy efficient profile due to its uniqueness as extensive mass rail transit networks, high density and compact urban formation, compact space oriented life style. The other feature is extensive use of electric heat pumps (EHP), which entails low carbon city profile. Further possibility is prepared with water thermal energy utilization, which is widely available also through EHP particularly in Tokyo central districts, which could make Tokyo one of the lowest carbon cities in the world. Emerging mega-cities are expected to learn from Tokyo's success and not from western conventional models.

  8. Energy Transition and Barriers on the Path to its Introduction

    Directory of Open Access Journals (Sweden)

    Tomislav Tkalec

    2015-12-01

    Full Text Available Energy transition is a concept originating from the necessity of solving environmental problems and conflicts in the energy sector. It originates from environmental tradition and advocates transition from environmentally and socially controversial sources of energy to renewables. That also means a shift from large centralized production units (mainly based on fossil and nuclear energy to smaller, dispersed ones. This decentralization process inherently leads to a democratization of the electricity sector, as large energy companies are losing their power and position in the energy policy arena, as more and more smaller actors emerge. However, when trying to change the electricity system, many obstacles arise – from the economics, old energy paradigm, path dependence, inertia of electricity system, power relations between actors, institutional lock-in, to perceptions and values of the dominant players. All barriers are reflected in the energy policy arena, dominated mainly by large energy companies, reluctant to accept changes. Demands for a change come from non-dominant actors, mainly from civil society actors and others, who are pushed to the margins of the political arena. Therefore, decision-makers should recognize their role, change institutional structure of the energy policy arena, and open it to various actors that can add new qualities to decision-making processes and outputs.

  9. Energy transition. Between reform and revolution

    International Nuclear Information System (INIS)

    Laville, Bettina

    2014-07-01

    The author comments the content of the French bill project on energy transition. She first discusses the meaning of this concept of energy transition which can be perceived as an evolution, a transformation, a progressive change, rather than a revolution. She recalls the original debate between those who wanted to preserve nuclear energy because it does not produce CO 2 emissions, and those who wanted a more radical change of the energy system. In this respect, she outlines and comments the main statements made by the French President on these issues, and indicates the main measures defined in the bill project regarding the reduction of greenhouse gas emission, the increase of the share of renewable energies, a decrease of the share of nuclear in power production, and a reduction of energy consumption. Then, she discusses how this transition is to be financed, proposes an assessment and a discussion of the skills and shortcomings of the bill project. She notably states that the main shortcoming is the lack of strong objectives regarding the reduction of emissions by transports, and the development of inter-modality. She also regrets the disappearance of the regional public service of energy efficiency, the fact that electricity consumption is not capped. Because of that, it's not that sure that the reduction of greenhouse gas emission by a factor 4 in 2050 with respect to 1990 will be reached. In the next parts, the author discusses the issue of the ecologic tax policy, outlines the importance of being exemplary within the perspective of the 2015 Conference on Climate (COP21)

    Energy transition is currently the subject of a wide-ranging national debate. Whatever the options that are retained, one thing is certain: the electricity system in France and in Europe will be confronted with profound changes. As of now, the main vectors for the development of electricity distribution, in France and in Europe, are the indispensable solidarity among territories and the rising flows of electricity from renewable sources.

    The paper analyses possible implications for Croatia of a global transition towards new energy technology systems, as depicted by the recent report on scenarios and strategies to 2050 of the International Energy Agency [ETP2008]. The analysis is based upon the present Croatian energy balance. It takes into account some draft results of the USAID-supported Regional Energy Demand Planning (REDP) study under the South East Europe Regional Energy Market Support (SEE REMS) Project. The paper then presents ongoing EC-funded energy research projects, such as RES2020 (Monitoring and Evaluation of the Renewable Energy Sources directives implementation in EU27 and policy recommendations for 2020), REACCESS (Risk of Energy Availability: Common Corridors for Europe Supply Security) and REALISEGRID (REseArch, methodoLogIes and technologieS for the effective development of pan-European key GRID infrastructures to support the achievement of a reliable, competitive and sustainable electricity supply). The participation of Croatian research organizations to EC-funded research projects could make the transition towards new energy system an opportunity for economic development.(author)

    The first part of this report proposes an overview of the present situation for climate-energy policies in France. It outlines the lack of transversality of local climate-energy policies which tend to be rather sector-oriented, the lack of coherence of these policies, their lack of efficiency due to a weak power of decision of local communities and to their lack of financial means, and the fact that the territorial organisation is not well adapted to climate-energy stakes. The second part presents and comments a set of proposals: to strengthen the region and the inter-communal levels, to give to local communities political and legal means of action, to reinforce human and financial means dedicated to energy transition, and to strengthen survey, follow-up and assessment missions

    Even though it is a fossil energy, gas has a role to play in energy transition as it emits less CO 2 than oil or coal. In this context, it can be used to fill the gaps due to intermittency of some renewable energies, and moreover can also be obtained from organic matter, and then becomes also a renewable source. A set of articles addresses and illustrates these different issues: the development of technologies to exploit methane, the role of substitute for gas, the assets of methane, of natural gas and of biogas, the transformation of electricity into gas in order to easily store energy (notably in the network gas according to the power-to-gas principle), the development of biomass-based methane, the replacement of oil by LNG (liquefied natural gas) in industry and transports (road and sea transport notably)

    International Nuclear Information System (INIS)

    2016-07-01

    A great ambition underlies France's Energy Transition for Green Growth Act: to make France - following on from the Paris Climate Summit - an exemplary nation in terms of reducing its greenhouse gas emissions, diversifying its energy model and increasing the deployment of renewable energy sources. This Act provides a unique opportunity both for climate negotiations and for France. It sets goals and implements operational solutions which can be shared with different regions, companies, researchers, the public and anyone with a long-standing commitment to fighting climate change. The Energy Transition for Green Growth Act and its attendant action plans are designed to give France the means to make a more effective contribution to tackling climate change and reinforce its energy independence, while striking a better balance in its energy mix and creating jobs and business growth. The texts required for its implementation are operational and support plans are in place. These tools are available to private individuals, businesses and the regions, enabling them to take concrete action. This document summarizes the actions under way: Defining common objectives, Acting together, Renovating buildings, developing clean transport, Tackling waste and promoting the circular economy, Promoting renewable energy, optimising nuclear safety and public information, Simplifying and clarifying procedures

  17. Making the most of distributed energy

    International Nuclear Information System (INIS)

    Malkamaeki, M.

    2004-01-01

    Distributed energy production is on the threshold of a new area, and offers a growing number of options for meeting energy needs that cannot be met effectively by larger, base load-type infrastructure. Distributed energy generation can offer a more cost- effective approach, depending on things such as location, load requirements, and fuel availability. It can also make it possible to generate energy at times when grid power is not available or is likely to be overloaded, and in locations not covered by an existing grid net-work. Perhaps most interesting from a technological point of view is the fact that distributed power opens up the opportunity to use fuels that have not been utilised up until now, for a variety of reasons

    The growing complexity of international relations, involving nations with vastly diverse political and socio-economic frameworks, levels of technology, geography, and environmental policies, are necessitating new Italian government policies which favour multilateral as opposed to conventional bilateral cooperation, especially in that which regards energy agreements. This paper makes this point in examining Italy's vulnerable energy supply and demand situation, the current directions being taken in this nation's foreign policies, and in assessing the key political and socio-economic factors now influencing this nation's world competitiveness in light of pending European unification and the opening up, on a wide scale, of Russian markets to Western nations and Japan

  20. The geopolitical challenges of energy transition

    International Nuclear Information System (INIS)

    Lafargue, Francois

    2013-01-01

    As China became in 2010 the first energy consumer in the world, the author gives an overview of the development of energy demand and of nuclear plants in China and in India, and evokes their situation with respect to international nuclear treaties and to their relationship with international bodies. The author then evokes the evolution in the USA where the exploitation of shale gases could result in a drastic reduction of their energetic dependence, but with a negative impact on the environment. Europe is more restrictive on this issue whereas China could also develop this sector. The action of China in the oil sector is also evoked. The author comments the general but slow evolution towards an energy transition with an increase of production of renewable energies, and then the new geographical context of energy production due to these evolutions of energy sources and productions. In a last part, the author gives a rather pessimistic vision as he thinks that an energy crisis is probably to occur

    Butler, C.; Demski, C.; Parkhill, K.; Pidgeon, N.; Spence, A.

    2015-01-01

    In the UK there are strong policy imperatives to transition toward low carbon energy systems but how and in what ways such transitional processes might be realised remains highly uncertain. One key area of uncertainty pertains to public attitudes and acceptability. Though there is wide-ranging research relevant to public acceptability, very little work has unpacked the multiple questions concerning how policy-makers can grapple with and mitigate related uncertainties in efforts to enact energy systems change. In this paper, public acceptability is identified as an indeterminate form of uncertainty that presents particular challenges for policy making. We build on our existing research into public values for energy system change to explore how the outcomes of the project can be applied in thinking through the uncertainties associated with public acceptability. Notably, we illustrate how the public values identified through our research bring into view alternative and quite different problem and solution framings to those currently evident within UK policy. We argue that engagement with a wide range of different framings can offer a basis for better understanding and anticipating public responses to energy system change, ultimately aiding in managing the complex set of uncertainties associated with public acceptability. - Highlights: • We argue that public acceptability represents an indeterminate form of uncertainty. • This means alternative approaches to decision-making are required. • We introduce a public value set for energy system change. • We use this as a basis for interrogating current UK policy approaches to transitions. • Incorporating public values in policy can help tackle uncertainty about acceptability.

  3. Mid-point review of the German energy transition

    Lauer, H.; Safa, H.; Guidez, J.

    2017-01-01

    The result of the 2015 review of the German energy transition is lukewarm. First: generating 20 % of the electricity production through wind power and solar energy appears to be very costly in Germany. Secondly there is practically no effect on the reduction of CO_2 releases as coal has been re-introduced to play the role of nuclear energy which was carbon-free to counter-balance the intermittency of renewable energies. Thirdly a necessity to keep all thermal plants ready to operate in order to cope with the intermittency of renewable energies as no adequate means of energy storage is available, appears to be a luxury that only Germany can afford. And fourthly, the cost of electric power for households and small enterprises is all the higher as the government economic policy is to spare German electro-intensive industry. One of the side effects of the German energy transition policy is to disturb the European market of electricity when favourable climate conditions make green electricity very abundant. In this situation electricity prices drop sharply and can even become negative while green electricity is always paid to the producer at a steady price guaranteed by the state. (A.C.)

    1992-01-01

    Energy, an important subject, cannot be validly discussed alone. For some time already, most experts agree that is necessary to include the environmental effects if one seeks a valid discussion. It appears now this was especially pointed out by the dramatic changes in Russia and other Eastern and Central European countries that the only efficient way to discuss energy is even more global. That discussion should, of course, include economics and the politico-economic system, but also society-people's motivations, mentality, education and finally a touch of philosophy, notably value systems. The debates of the third MIEC conference were characterized by their interdisciplinary character. The organizers tried to address these different issues by having them discussed together while emphasizing in different sessions specific aspects like economics and political system society, education, and value system and finally scientific and technical aspects of new energy technology. This meeting presents 28 papers of which 15 are in the INIS and Energy database scope. In the first and the second issue, the subject studied is energy policy in transition economy. The third issue describes the relationships between energy, environment and society. In the two last issues, the problems of safety in nuclear industry are studied

  5. Building concepts for a transition towards energy neutrality in 2050

    In this paper building concepts for the near future are described which enable the transition towards a net energy neutral building sector in the Netherlands by the year 2050. With 'net energy neutrality' is meant that, on a yearly basis, the total energy consumption in the built environment is compensated by local renewable energy production e.g. by using solar thermal (T), photovoltaic (PV), PVT and/or wind. A study concerning the feasibility of a 'net energy neutral built environment by 2050' set the energetic ambitions for the building concepts to be developed. This resulted in different concepts for residential buildings and for office-buildings. The building concepts are based on passive house technology to minimise the heating and cooling demand, and make optimal use of active and passive solar energy. Concepts for new to build domestic buildings are in fact energy producing to compensate for the remaining energy demand of existing, renovated dwellings. In all concepts the 'trias energetica' or 'energy pyramid' served as a general guideline, striving for minimisation of energy demand, maximal usage of renewable energy and usage of fossil fuels as efficiently as possible. Different full roof integrated options for using solar energy (PV, T or PVT) with variable storage options have been compared by making simulations with a dynamic simulation programme, to gain insight on their impact on energy, building engineering and economic impact. Also different possibilities for installations to fulfil the heating demand for the space heating and DHW demand are compared. For each concept, the resulting primary energy profiles for space heating and cooling, domestic hot water, electricity consumption for lighting, ventilation and household appliances are given.

  6. 30 Energy Cities' proposals for the energy transition of cities and towns

    International Nuclear Information System (INIS)

    2014-01-01

    In 2012, Energy Cities initiated a collective process aimed at making proposals to accelerate the energy transition of European territories. The 30 Proposals presented in this document are the result of part of this collective work. Other proposals are available on the Internet. These Proposals are based on the observation and analysis of hundreds of practical examples, all stemming from existing practices. Our intention is to make these practices 'talk', to convey their meaning and to show the path they are pointing at, sometimes without us being aware of it. The criterion for selecting these Proposals is straightforward and concerns their transforming capacity, that is, their ability to change the way we think and act. Specific attention has therefore been given to all aspects of innovation, including territorial governance. These Proposals aim to 'recreate society' through a subject which concerns us all, energy, and beyond this, to open avenues to the transition towards a more humane economy, more attuned to the challenges of the century. Proposals: 1 - Empowering local players: Take local control of energy supply; Unite all stakeholders in a local energy alliance; Ensure public budgets integrate positive and negative energy externalities; Co-create a long-term vision to shape all policies; Eradicate local fuel poverty; Lead by example by transforming municipal energy management; Prepare an Energy Transition Action Plan; Be part of regional, national and European networks to gain exposure to others' experience; 2 - Knowing our territories' resources and flows: Know the territory's metabolism so as to optimise local potential and reduce the impact of human activities on the ecosystem; Identify local energy potential in order to live within our means; Prepare a local heat plan to match need and available resource; Create and implement a territorial bio-waste action plan; Make the best use of energy and material flows by encouraging synergies between players; Make

    The differential energy distribution for electrons and taus produced from lepton pair production from muons in transit through materials is numerically evaluated. We use the differential cross section to calculate underground lepton fluxes from an incident atmospheric muon flux, considering contributions from both conventional and prompt fluxes. An approximate form for the charged current differential neutrino cross section is provided and used to calculate single lepton production from atmospheric neutrinos. We compare the fluxes of underground leptons produced from incident muons with those produced from incident neutrinos and photons from muon bremsstrahlung. We discuss their relevance for underground detectors.

    If, to lay the foundations of the European Community of Steel and Coal (ECSC), the founding fathers of Europe had waited for the steelworks belonging to the Krupp family and the Creusot foundries to decide of their own accord to work closer together, the European Union would simply not have been created. Even today an ambitious European energy strategy cannot materialise unless it is supported by France and Germany. A political agreement is indeed necessary given the complexity of the market and the interplay of both public and private factors. Energy strategies in France and Germany have remained far too national, sometimes going as far as to diverge, which makes no sense in the context of European integration. The resulting incoherence has prevented the pooling of industrial investments at the very moment European energy markets are increasingly integrated and European industrialists are at risk of being outrun, both technologically and commercially, by their foreign competitors. On the occasion of the 50. anniversary of the Elysee Treaty France and Germany have tried to renew energy cooperation admitting that they face similar challenges in terms of energy transition and that they would have everything to gain by working together to rise to those challenges. Ideas were put forward which should be clarified, completed and made into a reality. Indeed there is a rare opportunity for a vast bilateral cooperation project consistent with the two countries' responsibility towards Europe. The objection over the disparity of energy choices between France and Germany, in terms of electricity production could be solved if we acknowledge that the markets and issues associated with energy transition extend beyond our national borders. Basically this means having quite an ambitious political vision of the constructive, coherent governance of energy transition. (authors)

    2014-04-01

    As the Pays-de-la-Loire region has been committed for three years in the preparation for energy transition, this publication first recalls the main objectives to be reached by 2050 regarding energy consumption, electric power consumption, oil consumption by the transport sector, and greenhouse gas emissions. It outlines the need for a national strategy on the long term for energy transition, and presents the adopted approach for the elaboration of such a regional strategy, based on several experiments. The main axes of this strategy are then presented: to better and less consume energy (through thermal renovation, sustainable mobility, energy efficiency, energy saving behaviours), to make energy transition the engine of territory development (through a support to sectors, the development of regional energy production, and optimisation of consumptions and productions), and to elaborate tools for cooperative action

  10. Transition without Conflict? Renewable Energy Initiatives in the Dutch Energy Transition

    Directory of Open Access Journals (Sweden)

    2018-05-01

    Full Text Available In the context of the slowly progressing energy transition, a number of renewable energy initiatives have been emerging in the Netherlands. These initiatives represent alternatives to the dominant functioning of the energy system, and as such, may come into conflict with it. Transitions involve system destabilisation and conflict between the incumbent regime and the initiatives originating in niches. In order to assess the transformative potential of such initiatives, this paper addresses the question: what kind of conflicts and tensions arise from renewable energy initiatives, and what strategies do they develop to overcome or avoid them? Combined with a business model perspective, transition thinking enabled a better understanding of how the initiatives organise themselves, and where the points of friction with their institutional context emerge. We suggest that the instances of conflict may function as an indication for the state of the energy transition and the transformative potential impact of such initiatives. The instances discussed in this contribution relate to existing support schemes, technology choices, and the overall organisational networks of the emerging sector.

    Energy blockchain experiments and pilots are multiplying, driven by tech-savvy entrepreneurs. It looks like the new technology is disrupting the energy system from Spain to the US. What is in it for cities? Energy Cities makes sense of the blockchain buzz with this publication. The blockchain is not just for techies: after stirring up financial markets through the virtual currency bitcoin, the blockchain technology is quickly conquering other industries and markets - notably energy. The energy sector has been undergoing radical transformations, from decentralization, new storage technologies to the advent of artificial intelligence in managing supply and demand. Can the disruptive blockchain technology support cities in tackling these drastic and quickly unfolding changes? In this study, Energy Cities deciphers the potential role of blockchain in the local energy transition. How does it work and what does it impact concretely? How can it be applied in local energy systems? What are the opportunities and threats associated with this new technology that local governments should know about? Can it strengthen cities' role in the energy market or will it entrench the reign of the dinosaur utilities? These questions are explored in this study, and a comprehensive overview of ongoing relevant blockchain energy projects for cities is given

  13. The role of nuclear energy in times of energy transition

    International Nuclear Information System (INIS)

    2012-01-01

    Since the reactor catastrophe in Fukushima, the risk of nuclear power has once again become more evident to the public and has also led to a rethinking of politics in Europe. Slogans like ''Nuclear Power, No Thanks!'', ''Get Out of Euratom'' are making more and more the rounds. The phase-out of nuclear energy is the topic that is increasingly provoking people to think. But how should one handle this? What role will nuclear energy play in a distant future? Central factors such as the economic viability of renewable energy sources and the environmental and social compatibility of production and distribution must be taken into account, while at the same time the reduction of pollutants and greenhouse gases must continue. If this is done without nuclear energy, is the rapid abandonment of nuclear energy even necessary or does nuclear energy generation have to be used as a temporary solution? (roessner)

    Power and heating generation sector and transport sector contribute a highest GHG emissions and even air pollutions. This paper seeks to investigate life cycle costs and emissions in both the power sector and transport sector, and evaluate the cost-emission efficient (costs for one unit GHG emissions) of the substitution between new energy vehicles and conventional gasoline based vehicles under two electricity mix scenarios. In power sector, wind power and PV power will be cost comparative in 2030 forecasted with learning curve method. With high subsidies, new energy cars could be comparative now, but it still has high costs to lower GHG emissions. When the government subsidy policy is reversible, the emission reduction cost for new energy vehicle consumer will be 900/ton. According to the sensitive analysis, the paper suggests that the government implement policies that allocate the cost to the whole life cycle of energy production and consumption related to transport sector energy transition and policies that are in favor of new energy vehicle consumers but not the new energy car producers.

  17. The challenges of energy markets in transition

    International Nuclear Information System (INIS)

    Dumas, D.

    1999-01-01

    The transition period includes the processes as follows: liberalization, deregulation, privatization and restructuring. Liberalization consists of multiple changes: 1. Ownership - from public to private; 2. Industry structure - from vertically integrated to unbundled; 3. Market competition - from monopoly to competitive; 4. Product-mix - from single to multi-products; 5. Market approach - from service to product (wholesale); 6. System management - from self-managed to decentralized; 7. Planning horizon - from long to short term and 8. Participants - from national to trans-national. The energy sector is to ensure a reliable, long-term supply of energy in sufficient quantities at affordable prices from processes that are compatible with prudent environmental standards. The evolutionary model of an energy utility foresees a transition from traditional utility (integrated monopoly utility) through local wholesale trading and partial competition (competition for large customers) to competition for all customers and to redefined utilities (bundling multi-product services). Substantial liberalization of electricity have taken place as follows: in 6 countries in Western Europe and 12 plan to do it; in 4 countries in Eastern Europe and 8 - plan to do it; in 2 countries in Asia and Australasia and 12 plan to do it; in 4 countries in South America and 3 plan to do it. There is no liberalization of electricity in Central and North America till now but 6 in Central and 3 in North America plan to do it in future. Substantial liberalization of downstream gas have taken place: only in one country in Western Europe but 6 plan to do it in future; also in one country in Asia and Australasia and 3 plan to do it; in one country in South America and 2 plan to do it and in two countries in North America and only one plan to do it in future. The goals of liberalization include: reducing the cost of energy; improving economic efficiency; attracting capitals and paying off government debt

    2014-01-01

    As the French President called for the creation of a French-German company dedicated to energy transition, inspired by the Airbus project which emerged to share the design and development costs of a specific product (a large capacity aircraft), this article comments the possibility of applying such a strategy between the main French and German actors like Siemens, RWE, Alstom, EDF. Such an idea has already its reality as some French and German are cooperating in different projects: offshore wind energy consortium, research and development in photovoltaic, smart grids, energy storage, and so on. Some of these projects are evoked and commented, for example one which has emerged just after the President's speech: the project of a giant factory of solar arrays proposed by the CEA and the Fraunhofer Institute. One major need is also evoked, the harmonization at the regulation stage

    International Nuclear Information System (INIS)

    Hancock, S.

    1991-01-01

    The standard derivations of the energy and phase of the synchronous particle in a proton accelerator assume, as if by definition, that said synchronous particle lies on the central orbit of the machine. This is manifestly unjustified in the particular case of the acceleration near transition of a mixture of ions, when a small difference in charge-to-mass ratio can produce a large radial separation of the different ion species. The development of a simple derivation of the parameters of the synchronous particle that involves no such a priori constraint has yielded some surprises; not, least, a belated explanation for an apparent anomaly encountered in 1987, when a mixture of oxygen and sulphur ions was accelerated in the CERN Proton Synchrotron for the first time. These ideas are supported by measurements performed in 1990 during a second ion run

    There is little systematic information about the impact of energy sector reform on all sources and methods of energy utilised or potentially utilised by the poor. It is not sufficiently known what fuels the poor use, if a larger range of fuels becomes available and affordable and if barriers to access and consumption are reduced. A detailed assessment is presented for four countries, three in Africa (Botswana, Ghana and Senegal) and for comparison one in Latin America (Honduras), of steps taken to reform the energy sector and their effect on various groups of poor households. The paper analyses the pattern of energy supply to, and use by, poor households and explores the link-or its absence-to energy policy. We investigate what works for the poor and which type of reforms and implementation are effective and lead to a transition to more efficient and clean fuels from which the poor benefit. Energy sector reforms when adjusted to the specific conditions of the poor have a positive impact on access and use of clean, safe and efficient fuels. The poor are using gradually less wood as cooking fuel. Gas and kerosene are made more widely available through market liberalisation and subsidy in the particular case of Senegal. Electricity access and use is generally promoted or subsidised through changes in payment conditions and lifeline tariffs

  2. Harvesting energy: Place and local entrepreneurship in community-based renewable energy transition

    International Nuclear Information System (INIS)

    Süsser, Diana; Döring, Martin; Ratter, Beate M.W.

    2017-01-01

    Transition towards a renewable energy supply initiates a physical (re)shaping of places and a social transformation of communities into renewable energy communities. Although socio-cultural challenges of energy transition have been recognised (), understandings about socio-geographic places of energy transition and their underlying social processes and structures are insufficiently studied and often remain underestimated. To close this gap, we theoretically and empirically analysed the multifaceted interplay between place, local entrepreneurship and ‘community renewable energy’. Our study is based on an analysis of regional documents and policy reports, and on qualitative interviews undertaken with inhabitants in the case-study municipality of Reußenköge (Germany). Our findings reveal two important aspects: Firstly, people's individual and shared place meanings which materialised in social, physical, historical and climate-related place-attachments and meanings of contested and innovative place are important ingredients bearing an impact on processes of adopting or rejecting renewables. Secondly, differentiated characteristics of entrepreneurs, namely grounded, collaborative, innovative, change-making, economic, communicating, networking and political aspects, appeared to be relevant for the acceptance and support in community-based renewable energy projects. Our findings reveal that energy policies, funding schemes and administrative structures should recognise local socio-geographic important elements in the context of a sustained and decentralised energy transition. - Highlights: • Places are resources of experiences, creativity and innovation for community renewables. • Energy policies should recognise place-based approaches to grassroots community energy actions. • A located view of multifaceted entrepreneurship is relevant to support community renewable energy. • Supportive funding schemes should empower community-based concepts.

    Regulatory requirements introduced by the new policy of energy transition will force the French industry to look for alternatives to oil and coal. Within this context, this publication contains contributions proposed by industrial and academic experts which aim at discussing how the French industry can seize the opportunity of energy transition to strengthen itself. The authors discuss the issue of competitiveness, the role of de-carbonated electricity, the context of energy transition in France, the evolutions and transformations of the energy market. They also outline the lack of an energy vision in France, the role of the electricity grid as a vector of energy transition, and the fact that the debate on energy transition did not result in concrete solutions

  7. Year 2 of Germany's Energy Transition

    Cruciani, Michel

    2013-01-01

    After a decade characterised by the take-off of renewable energies, Germany decided in 2010 to make them the top priority. At the same time, it decided to make exemplary efforts in terms of energy efficiency and the reduction of greenhouse gases. The audacious nature of this policy was strengthened by the 'turn' taken in 2011 to give up nuclear energy in the wake of the Fukushima accident. Given the initial results for 2012, Germany seems to be on target for reaching its national objective, of 18% renewable energy within total consumption by 2020. Germany is also well placed to reduce its planned cut in electricity consumption of 10%. The country will also meet its commitments, both international and European, concerning greenhouse gas emissions. In contrast, recent trends suggest it will be increasingly difficult for Germany to meet its own, domestic goal of cutting emissions by 40%, by 2020. Furthermore, it is hard to see how Germany will be able to bring down total energy consumption by 20% by 2020 (from 2008 levels), or increase the share of renewables in electricity production above 35%. Success with this latter objective is largely dependent on reinforcing networks, both for transmission over long distances and for local distribution. It is not sure that the delays accumulated in both areas will be made up for by 2020, despite the rapid legislative adjustments that have already been made. By favouring intermittent energy sources - wind and solar power - Germany also faces problems of managing frequent production fluctuations. The long term solution to this lies in storing electricity. However, despite the considerable efforts in research and development, the technologies necessary for this will doubtless not be available on a large scale before the end of the present decade. These efforts could nevertheless provide German industry with interesting advantages in sectors of high potential, such as electric vehicles. Measures to promote renewable energies are

    2017-09-01

    The clean energy transition requires a co-evolution of innovation, investment, and deployment strategies for emerging energy storage technologies. A deeply decarbonized energy system research platform needs materials science advances in battery technology to overcome the intermittency challenges of wind and solar electricity. Simultaneously, policies designed to build market growth and innovation in battery storage may complement cost reductions across a suite of clean energy technologies. Further integration of R&D and deployment of new storage technologies paves a clear route toward cost-effective low-carbon electricity. Here we analyse deployment and innovation using a two-factor model that integrates the value of investment in materials innovation and technology deployment over time from an empirical dataset covering battery storage technology. Complementary advances in battery storage are of utmost importance to decarbonization alongside improvements in renewable electricity sources. We find and chart a viable path to dispatchable US$1 W-1 solar with US$100 kWh-1 battery storage that enables combinations of solar, wind, and storage to compete directly with fossil-based electricity options.

    Facing global climate change and scarce petroleum supplies, the world must switch to sustainable energy systems. While historical transitions between major energy sources have occurred, most of these shifts lasted over a century or longer and were stimulated by resource scarcity, high labor costs, and technological innovations. The energy transition of the 21st century will need to be more rapid. Unfortunately, little is known about how to accelerate energy transitions. This article reviews past transitions and factors behind them, along with their time frames. Three modern case studies are discussed: Brazil, which shifted from an oil-based transportation system to one based on sugarcane-ethanol (success); France, which shifted from oil-fired electric power to nuclear power (success); and the United States, which attempted to shift from foreign oil to a mix of domestic energy resources (failure). Lessons from these attempts to govern energy transitions are discussed. Several policy instruments to accelerate a transition are identified, though even under ideal circumstances a global energy supply transition will be very slow. Given the need to simultaneously implement programs in countries with different political economies, a greater focus on energy efficiency, promotion of Smart Grids, and possibly a new treaty should yield more timely results. - Highlights: → We review the historical evidence on major energy transitions worldwide. → Case studies are presented of successful energy transitions in Brazil and France. → The United States provides an example of an unsuccessful energy transition. → We argue that a transition focused on energy efficiency can occur much more rapidly.

    Intelligent measuring systems are important components in the intelligent net and require security and privacy by design in this critical infrastructure. The smart meter gateway as secure communication platform makes the digital sector coupling possible and becomes the driver for innovations of the digitalization. The protection profiles and the technical rules of the BSI as essential part of the law for the digitalization of the energy transition guarantee a great amount of data protection and data security and provide a unique security standard in the future energy supply system. The data -protection concept of the intelligent measuring system regards a calibration-law conformal data processing and star-shaped data dispatch of the gateway. By this both a traceability and a transparency for the final user is guaranteed and the handling of the data in the sense of the data sovereignty is also technically enforced. For the evidences of compliance of the protection profiles and the technical rules correponding tests in approved test centers with final certification by the BSI are performed. The law for the digitalization of the energy transition makes the first important step to an innovative, digital infrastructure of the intelligent net. By the legal framework additionally a base is created, in order to perform a progressive development of the security targets of the BSI both for intelligent measuring systems as for further important system components of the intelligent energy net via a roadmap for the digitalization. In connection with the technical standards of the BSI the law creates the necessary legal certainty and realizes the aim pursued in the coalition treaty to regulate binding framework conditions for the secure and data-protection conformal application of intelligent measuring systems for diversified application cases in the intelligent net.

    The problems of the transportation energy and environment are the major challenges faced globally in the 21st century and are especially serious for China. The future 20 years is the strategic opportunity period of the transition of the transportation energy and powertrain system for China. The greatest characteristics of hydrogen economy lie in its diversity of the primary energy source, the unification of energy carrier and the greening of energy transformation. Development of hydrogen energy transportation powertrain system is suitable for China from the views of the situation of Chinese resources and energy sources, the urban and rural layouts, the superiority of later development and the successful practices of clean cars and electric vehicle development projects. The transition of the transportation energy powertrain system includes three parts: the transition of the energy structure, the transition of the powertrain system and the transition of the fuel infrastructure. The technical pathways of energy powertrain system transition includes expending the use of gaseous fuel to prompt the multiform of the transportation energy and to prepare for the transition of the infrastructure simultaneously, developing and promoting the hybrid technology to solve the current energy and environment problems and to prepare for the transition of powertrain system, and focusing on the research and development and demonstration of fuel cell vehicles and the hydrogen energy technology to prompt the earlier formation of the market of fuel cell vehicles. The goal in the near and medium term of transition is to reduce the fuel consumption by 100 million ton in 2020 by substituting and saving, and the long-term goal is to setup the infrastructure of hydrogen and fuel cell vehicle as the main one replacing the petroleum internal combustion engine vehicle. In order to realize the strategic goals of the transition, the four-phases strategic periods and research and development

    Science.gov (United States)

    Rowse, Tarah

    While global, national, and regional efforts to address climate and energy challenges remain essential, local governments and community groups are playing an increasingly stronger and vital role. As an active state in energy system policy, planning and innovation, Vermont offers a testing ground for research into energy governance at the local level. A baseline understanding of the energy planning and energy organizing activities initiated at the local level can support efforts to foster a transition to a sustainable energy system in Vermont. Following an inductive, applied and participatory approach, and grounded in the fields of sustainability transitions, energy planning, and community energy, this research project identifies conditions for change, including opportunities and challenges, within Vermont energy system decision-making and governance at the local level. The following questions are posed: What are the main opportunities and challenges for sustainable energy development at the town level? How are towns approaching energy planning? What are the triggers that will facilitate a faster transition to alternative energy systems, energy efficiency initiatives, and localized approaches? In an effort to answer these questions two studies were conducted: 1) an analysis of municipal energy plans, and 2) a survey of local energy actors. Study 1 examined Vermont energy planning at the state and local level through a review and comparison of 40 municipal plan energy chapters with the state 2011 Comprehensive Energy Plan. On average, municipal plans mentioned just over half of the 24 high-level strategies identified in the Comprehensive Energy Plan. Areas of strong and weak agreement were examined. Increased state and regional interaction with municipal energy planners would support more holistic and coordinated energy planning. The study concludes that while municipalities are keenly aware of the importance of education and partnerships, stronger policy mechanisms

  14. Soft Energy Paths Revisited: Politics and Practice in Energy Technology Transitions

    Directory of Open Access Journals (Sweden)

    Chelsea Schelly

    2016-10-01

    Full Text Available This paper argues that current efforts to study and advocate for a change in energy technologies to reduce their climate and other environmental impacts often ignore the political, social, and bodily implications of energy technology choices. Framing renewable energy technologies exclusively in terms of their environmental benefits dismisses important questions about how energy infrastructures can be designed to correspond to democratic forms of socio-politics, forms of social organization that involve independence in terms of meeting energy needs, resilience in terms of adapting to change, participatory decision making and control, equitable distribution of knowledge and efficacy, and just distribution of ownership. Recognizing technological choices as political choices brings explicit attention to the kinds of socio-political restructuring that could be precipitated through a renewable energy technology transition. This paper argues that research on energy transitions should consider the political implications of technological choices, not just the environmental consequences. Further, emerging scholarship on energy practices suggests that social habits of energy usage are themselves political, in that they correspond to and reinforce particular arrangements of power. Acknowledging the embedded politics of technology, as the decades’ old concept of soft path technologies encourages, and integrating insights on the politics of technology with insights on technological practices, can improve future research on energy policy and public perceptions of energy systems. This paper extends insights regarding the socio-political implications of energy paths to consider how understandings of energy technologies as constellations of embedded bodily practices can help further develop our understanding of the consequences of energy technologies, consequences that move beyond environmental implications to the very habits and behaviors of patterned energy

    Both India and China are countries in energy transition. This paper compares the household energy transitions in these nations through the analysis of both aggregate statistics and nationally representative household surveys. The two countries differ sharply in several respects. Residential energy consumption in China is twice that in India, in aggregate terms. In addition, Chinese households have almost universal access to electricity, while in India almost half of rural households and 10% of urban households still lack access. On aggregate, urban households in China also derive a larger share of their total energy from liquid fuels and grids (77%) as compared to urban Indian households (65%). Yet, at every income level, Indians derive a slightly larger fraction of their total household energy needs from liquid and grid sources of energy than Chinese with comparable incomes. Despite these differences, trends in energy use and the factors influencing a transition to modern energy in both nations are similar. Compared with rural households, urban households in both nations consume a disproportionately large share of commercial energy and are much further along in the transition to modern energy. However, total energy consumption in rural households exceeds that in urban households, because of a continued dependence on inefficient solid fuels, which contribute to over 85% of rural household energy needs in both countries. In addition to urbanisation, key drivers of the transition in both nations include income, energy prices, energy access and local fuel availability. (author)

  17. Energy transition is an opportunity to be seized. Proposals and actual measures to speed up energy transition in France - May 2017

    International Nuclear Information System (INIS)

    2017-05-01

    After having outlined that energy transition could bring actual answers to essential concerns perceived by French people (economy revitalisation, purchasing power, employment, safety, life quality, democracy), this publication contains proposals and suggests measures which aim at making the energy sector evolve, can be either transverse, sector-based or specific, and could give an impulse to the French energy transition. More particularly, these measures and proposals aim at amplifying and speeding up the evolutions of the legal framework, at setting the initiative of economic actors free, at organising the financing of energy transition, at improving the quality of life for all citizen, at ensuring the sharing of benefits, and at considering the different relevant scales (from the local one to the global one)

    Rubio, M.d.Mar; Folchi, Mauricio

    2012-01-01

    This paper provide evidence of the early transition from coal to oil for 20 Latin American countries over the first half of the 20th century, which does not fit the transition experiences of large energy consumers. These small energy consumers had earlier and faster transitions than leading nations. We also provide evidence for alternative sequences (inverse, revertible) in the transition from coal to oil. Furthermore, we demonstrate that ‘leapfrogging’ allowed a set of follower economies to reach the next rung of the energy ladder (oil domination) 30 years in advance of the most developed economies. We examine these follower economies, where transition took place earlier and faster than the cases historically known, in order to understand variation within the energy transitions and to expand the array of feasible pathways of future energy transitions. We find that being a small energy consumer makes a difference for the way the energy transition takes place; but also path dependence (including trade and technological partnerships), domestic energy endowment (which dictates relative prices) and policy decisions seem to be the variables that shaped past energy transitions. - Highlights: ► We provide evidence of the early transition from coal to oil for 20 Latin American. ► We find that being a small energy consumer makes a difference for the way the energy transition takes place. ► Followers had earlier and faster transitions than leading nations. ► ‘Leapfrogging’ allowed extremely fast energy transitions. ► Alternative forms (revertible, inverse) of energy transition also exist.

    The 'Cartes sur table' think tank aims at leveraging the opinion of young French people (from 20 to 35 years old) politically leaning to the left, in order to let them become actors in French debates, such as the one on the energy transition policy for a 'green growth'. This paper explains the origins and the context of the energy transition policy (the dangers of nuclear power, the high potential of renewable energies, etc.), how to finance the energy transition policy, how to promote energy transition in the daily life (notably in transports and through the struggle against wastage), create a Europe of energy, and so on

    2005-12-01

    The energy economy in the Netherlands is not based on sustainability. The councils VROM-Raad and AER consider this a threat for our society. The present approach of the Dutch Ministry of Economic Affairs to realize a sustainable energy economy is a good start but must be extended and intensified to other sectors, e.g. housing, traffic and transport, and agriculture and the greenhouse sector. A number of recommendations is formulated: more cooperation with similar countries; setting up of a energy transition commission to manage and control the strategy of the transition process; setting up of a long-term financing system (energy transition fund) to make financial incentives for energy innovation less dependent of political and cyclical changes; intensification of the energy conservation measures; sharper selection of R and D programmes

    This report first gives an overview of the energy system by presenting the determining factors of energy demand and of CO 2 emissions per sector (housing and office building, transport, industry, agriculture, forestry and biomass), by analysing energy systems and CO 2 emissions (energy sources, energy vectors, networks and storage, energy and CO 2 assessment for France), and by describing the guidelines of the scenarios proposed by ANCRE. The three main scenarios are characterized by a stronger sobriety, an electricity-based de-carbonation (with a variant based on nuclear and renewable energies), and diversified vectors. They are notably compared to a trend-based reference scenario. Results are discussed in terms of energy consumption (primary and final energy, consumption by the different sectors), of energy production and CO 2 emissions. Scenarios are assessed in terms of economic, environmental and societal, political and strategic criteria. Some consequences for research topics and funding are identified

    Higher knowledge has long been hypothesized as leading to better acceptance of nuclear energy, but in the last years other factors such as risk perception and trust in nuclear risk governance were also recognized as key elements. While stakeholder involvement is now fully recognized as a key element for nuclear energy acceptance, there are still questions about the impact of higher knowledge. This paper investigates the relation between knowledge about the nuclear domain, risk perception of nuclear risks, confidence in the management of nuclear technologies, on the one hand, and the attitude towards nuclear energy and opinion about nuclear energy, on the other hand. It also studies the factors that are pleading in favour or against nuclear energy and their relation with the forementioned variables. The study is based on empirical data from a large scale opinion survey in Belgium between 25/05/2011 and 24/06/2011, i.e. the third month after the accident in Fukushima. The sample consisted of 1020 respondents and is representative for the Belgian adult population (18+) with respect to gender, age, region, province, habitat and social class. Our results show that confidence in the safe management of nuclear technologies as well as the perceived strength of the arguments pro/against nuclear are driving factors for people's attitude towards nuclear energy. Higher confidence and stronger adherence to the arguments in favour of nuclear energy lead to higher acceptance. The correlation between knowledge and attitude/opinion towards nuclear energy is statistically significant, but rather low, showing only a weak effect of knowledge on attitudes or opinions about nuclear energy. A weak effect is also observed for risk perception of nuclear risks, lower risk perception leading to a somewhat more positive attitude/opinion about nuclear energy. In the study we also highlight that the main factors seen as pleading in favour or against nuclear energy are the same, both for

  7. Italy: a national energy strategy in transition

    International Nuclear Information System (INIS)

    Spaes, Joel

    2014-01-01

    This article discusses the status and perspectives of the Italian energy policy. It outlines that this policy has known many changes during the past decades. The country has been depending for years on oil imports and on electricity imports from its neighbours even though ENI and ENEL are major world actors. It had chosen nuclear energy to gain independence until the Chernobyl accident which resulted in a moratorium. On the side of renewable energies, Italy has notably developed geothermal energy, and possesses an important hydraulic energy fleet, while solar photovoltaic and wind energy started their development rather late and still at a rather slow pace. Thus, a new energy strategy has been implemented in 2012 with some main objectives: reduction of energy costs, meeting of European objectives regarding energy and climate, improvement of energy supply security and of energy independence, and development of a sustainable economy through the development of the energy sector. This strategy resulted in very good results in terms of energy efficiency, and of growth rate for the photovoltaic sector

    In Saudi Arabia, industrial fuel prices are administered below international prices and firms make decisions based on low energy prices, increasing domestic energy demand. This analysis explores alternative policies designed to induce a transition to a more efficient energy system by immediately deregulating industrial fuel prices, gradually deregulating fuel prices, and introducing investment credits or feed-in tariffs. It uses a dynamic multi-sector, mixed-complementarity model. Continuing existing policies results in a power system still fueled completely by hydrocarbons. The alternative policies result in a transition to a more efficient energy system where nuclear and renewable technologies become cost-effective and produce 70% of the electricity in 2032. Introducing the alternative policies can reduce the consumption of oil and natural gas by up to 2 million barrels of oil equivalent per day in 2032, with cumulative savings between 6.3 and 9.6 billion barrels of oil equivalent. The energy system sees a net economic gain up to half a trillion 2014 USD from increased oil exports, even with investments in nuclear and renewables. The results are robust to alternative assumptions regarding the value of oil saved and the growth in end-use energy demand. - Highlights: • We model the effect of reforming fuel prices to industrial sectors in Saudi Arabia. • Alternate policies can lower oil and gas use by up to two million boe/day in 2032. • Large economic gains could be achieved by reforming industrial fuel prices. • Some pricing policies manage transition without compromising the economic gain. • Saudi Arabia can maintain large crude oil export capacity by 2032.

    This paper examines the determinants of credit allocation to renewable energy firms in developing and transition countries. Using a simple en- dogenous growth model, we show that the development of the renewable energy sector, i.e. the diversification of renewable energy resources used in primary energy production, depends on the quality of financial intermedia- tion, debtor information costs to banks, and financing needs of renewable energy firms. Policies should aim at increasing financial ...

  13. Energy policy decision making and public opinion

    International Nuclear Information System (INIS)

    Gerstein, L.

    1989-09-01

    By the example of nuclear the author demonstrates the interactions of short-term fluctuations on the world energy market, energy forecasts, specific events and discussions on energy policy both within political parties and in the general public, and draws conclusions which are valid beyond the Federal Republic of Germany: An analysis of the general public's attitude towards nuclear energy shows two initial phases, i.e. euphoria and scepticism/ideology/agitation. The early eighties, then, led to a third phase - realism. Up to 1983 a consensus prevailed between the leading political parties in Germany regarding the basic energy-policy objective of minimizing the supply risk by providing for a well-balanced use of all available energy sources. The resulting attitude had a positive bearing on the public opinion: more than two thirds of the population were in favour of nuclear. In the mid-eighties, the development of nuclear was by and large completed in the Federal Republic of Germany as well as in the United States and other western industrialized countries and the capacity of nuclear power plants is considered sufficient for the years to come. In addition, abundant long-term reserves of domestic lignite and hardcoal are available: this also should have furnished a good reason to envisage calmly the issues of power supply. Instead, we are again facing emotional discussions on the acceptance of nuclear. Public opinion in the Federal Republic of Germany has changed since the Social Democrats followed the example of the Ecologists and advocated a rapid withdrawal from nuclear. In a recent poll four-fifths of the persons asked did not rule out the possibility of a major accident in a German power station. The wish to ignore today's energy supply problems by escaping into a supposedly safe but yet distant and vague future is part of every public debate. Technical and scientific issues are examined no longer in this global context. Predictions of experts and counter

    With a continuously growing energy demand, the present energy model is clearly unsustainable due to the decline of fossil fuel resources and the risks of climate change A transition towards a sustainable model is therefore needed. However, there are no immediate alternatives leading to a sharp reduction in the use of fossil fuels, which are expected to maintain a major role for many years. The energy transition will therefore require a long time period The risks of climate change will require urgent measures and the 'carbon transition' has to be achieved more rapidly than the energy transition itself. A whole set of solutions will be needed in the technical but also economic and regulatory areas, for achieving a successful transition: energy conservation, diversification of energy . sources, reduction of the carbon content of the energy mix, CO{sub 2}, capture and storage. Hybrid options will be favoured. The paper describes the main features of the upcoming transition and the actions which are required. (auth)

    1992-01-01

    The kinetic energy released during seven unimolecular ionic transitions, generated from benzyl alcohol and benzyl amine have been studied as a function of ion source temperature and ionizing electron energy. Only, the kinetic energy released during H CN elimination from fragment [C 7 H 8 N]+ ion of benzyl amine displays a temperature dependence. For only two transitions, generated from benzyl alcohol, the kinetic energy released show a significant ionizing electron energy dependence. These results may reveal the role of the internal energy of reacting ions in producing the kinetic energy released some transitions produced from benzyl alcohol

The model predicts how the number of accessible basins on the energy landscape and, consequently, the film's ideal glass transition temperature depend on bulk pressure, film thickness, and the strength of the fluid-fluid and fluid-substrate interactions. The predictions are in qualitative agreement with the experimental trends for the kinetic glass transition temperatu...

  19. Energy Exchange Dynamics across L-H transitions in NSTX

    Science.gov (United States)

    Diallo, Ahmed

    2017-10-01

    H-mode is planned for future devices such as ITER, and is preceded by a low (L) to high (H) transition. A key question remains. What is the mechanism behind the L-H transition? Most theoretical descriptions of the L-H transition are based on the shear of the radial electric field and coincident ExB poloidal flow shear, which is thought to be responsible for the onset of the anomalous transport suppression that leads to the L-H transition. This talk will focus on the analysis of the flow dynamics across the L-H transition in NSTX. We analyze the L-H transition dynamics using the velocimetry of 2D edge turbulence data from gas-puff imaging (GPI). We determine the velocity components at the edge across the L-H transition for 17 discharges with three types of heating power (NBI, ohmic, and RF). Using a reduced model equation of edge flows and turbulence, the energy transfer dynamics is compared with the turbulence depletion hypothesis of the predator-prey model. In order for Reynolds work to suppress the turbulence, it must deplete the total turbulent free energy, including the thermal free-energy term. For this to occur, the increase in kinetic energy in the mean flow over the L-H transition must be comparable to the pre-transition thermal free energy. However, this ratio was found to be of order 10-2. Although there are significant simplifications in the theoretical model, they are unlikely to cause inaccuracy by two orders of magnitude, suggesting that direct turbulence depletion by the Reynolds work may not be large enough to explain the L-H transition on NSTX, contrary to the predator-prey model.

    2016-01-01

    Actually, the energy industry is affected in a changing market environment. The expansion of the renewables led to a share of about 30 % of the German electricity production and is always rising. The renewables energy levy has reached a level of 6.35 Euro Cents per kWh, which is actually a high level. Investments in new power plants are stopped due to low market electricity prices. The market pressure on the utilities is high and their business models have to be scrutinised. The NRW state government supports the magic political triangle of a secure, affordable and environmentally friendly energy supply. Instead of further interventions we have to develop our existing energy system cautiously. Anything else would not meet the requirements for invests in the energy supply and the magic triangle of energy politics.

    This note aims at examining whether environmental policies associated with energy transition are either a brake on, or an opportunity for economic growth. In order to so, the authors compare France's situation with that of its economic partners (Germany, Spain, Italy) in terms of energy price, and of share of employment in polluting industries. They also examine the influence of an increase of energy prices on employment and competitiveness of French manufacturing companies. They finally show that energy transition implies a structural change which may result in an actual creation of green jobs. They finally propose three recommendations regarding economic policy

  3. Can urban rail transit curb automobile energy consumption?

    International Nuclear Information System (INIS)

    Lin, Boqiang; Du, Zhili

    2017-01-01

    With the rapid development of China's economy and the speed of urbanization, China's automobile sector has experienced rapid development. The rapid development of the automobile sector has increased energy consumption. According to the results of this paper, automobile energy consumption accounted for about 10.73% of total energy consumption in China in 2015, about 3.6 times the proportion a decade ago. With the deterioration of urban traffic conditions, relying on expanding the amount of vehicles and city road network cannot solve the problem. Urban rail transit is energy-saving and less-polluting, uses less space, has large capacity, and secure. Urban rail transit, according to the principle of sustainable development, is a green transportation system and should be especially adopted for large and medium-sized cities. The paper uses the binary choice model (Probit and Logit) to analyze the main factors influencing the development of rail transit in Chinese cities, and whether automobile energy consumption is the reason for the construction of urban rail transit. Secondly, we analyze the influence of urban rail transit on automobile energy consumption using DID model. The results indicate that the construction of urban rail traffic can restrain automobile energy consumption significantly, with continuous impact in the second year. - Highlights: • Investigate the main factors influencing the building of rail transit for Chinese cities. • Analyze the influence of urban rail transit on automobile energy consumption by DID model. • The results indicate that the construction of urban rail traffic can restrain automobile energy consumption significantly.

    Barthet, Marie-Claire; Nedey, Fabienne; Tourneur, Jean-Claude

    2015-01-01

    In this set of articles, the first one comments the emergence of standard tools to assess energy efficiency within the frame of energy transition. These standards concern eight different fields and can be applied by enterprises and also used by local communities to assess their energy saving policy. The second article comments the content of a French standard elaborated by a professional association gathering actors of the illuminated sign and signing sector; this standard addresses the design and manufacturing of these products, and technical, energetic as well as aesthetic aspects. The third article presents and comments the application in Bordeaux and in Nantes of a new European directive for public lighting which resulted in a renewal of the installation. The fourth article comments the content of the French law on energy transition, notably regarding the production or improvement of buildings and dwellings to save energy, the development of cleaner transports, waste recycling, the development of renewable energies, and the struggle against energy poverty. The next article reports the main parts of an intervention of the German minister of Foreign Affairs on the German policy for energy transition (the so-called Energiewende). The last article comments the road-map for energy transition in Germany as it has been recently defined by the German government. Several topics are notably addressed: co-generation, energy efficiency, transformation of coal power plants, reduction of CO 2 emissions by the coal industry, extension of the electric grid, financing the dismantling of nuclear power stations

    Ramade, Francois

    2013-05-01

    After having outlined the almost unavoidable character of energy transition, the author shows that a combination of nuclear and renewable energies is the single possibility to maintain a sufficient level of energy production while avoiding a major climate change. He states that the decision to shut down the Fessenheim plant is not a good start for the debate on energy transition. He outlines that the risks evoked to justify this closure are not realistic. He discusses the technical and economic consequences of this closure, how Fessenheim could then be replaced in terms of energy supply. He discusses the relationship between employment on the one side, and nuclear or renewable energies on the other side. He briefly comments the German situation, outlines that nuclear energy is an alternative to the exhaustion of fossil hydrocarbon resources. He finally addresses the issue of definition of the energy mix

    Departing from the concept of rational use of energy, the paper outlines the microeconomics of end-use energy saving as a result of frugality or efficiency measures. Frugality refers to the behaviour that is aimed at energy conservation, and with efficiency we refer to the technical ratio between energy input and output services that can be modified with technical improvements (e.g. technology substitution). Changing behaviour from one side and technology from the other are key issues for public energy policy. In this paper, we attempt to identify the effects of parameters that determine energy saving behaviour with the use of the microeconomic theory. The role of these parameters is crucial and can determine the outcome of energy efficiency policies; therefore policymakers should properly address them when designing policies.

    1992-07-01

    As ANSI/ASQC E4, Quality Systems Requirements for Environmental Programs, nears final form and formal issuance by the American National Standards Institute (ANSI) and the American Society for Quality Control (ASQC), numerous organizations will be developing and implementing quality assurance programs based on the criteria promulgated by ANSI/ASQC E4. The organizations to initially adopt ANSI/ASQC E4 will be those that already have quality assurance programs based either on ASME NQA -1 or EPA QAMS-005/8. This paper presents the changes/enhancements required to transition an ASME NQA -1 or EPA QAMS-005/80 based quality assurance program to a program which meets the requirements of ANSI/ASQC E4

    Increasingly, researchers and policy makers are confronting the challenge of restructuring energy systems into more sustainable forms. A 'transition management' model, and its adoption in the Netherlands, is attracting attention. Starting from the socio-technical multi-level theory that informs 'transition management', we analyse the 'energy transition' project carried out by the Dutch Ministry of Economic Affairs. Despite considerable achievements, their approach risks capture by the incumbent energy regime, thereby undermining original policy ambitions for structural innovation of the energy system. This experience presents generic dilemmas for transitions approaches

    Energy Technology Data Exchange (ETDEWEB)

    Hills, Peter (Hong Kong Univ. (Hong Kong). Centre of Urban Planning and Environmental Management)

    1994-05-01

    A household energy survey in Hong Kong confirmed that domestic energy consumption is dominated by modern fuels. Household spending on fuels typically amounts to less than 3% of monthly income. Delivered energy use per household per month averages 1.77 GJ and per capita use 0.37 GJ. Electricity accounts for more than half of fuel expenditure and energy use. Patterns of fuel choice and use are quite consistent across income levels, although electricity use rises with higher household incomes. Many households use a combination of kerosene, gas and electricity (rice cookers) for cooking, which appears to reflect culinary practices more than fuel prices, perceived safety or availability. Electrical appliance saturation is high already, and air conditioning use is growing rapidly. Household electricity consumption may increase substantially during the 1990s as higher comfort levels lead to increased heating and cooling demand and space standards in public housing units improve.

    After a presentation of the energetic context and of its issues, this collective publication proposes presentations of various electricity storage technologies with a distinction between direct storage, thermal storage and hydrogen storage. As far as direct storage is concerned, the following options are described: pumped energy transfer stations or PETS, compressed air energy storage or CAES, flywheels, various types of electrochemical batteries (lead, alkaline, sodium, lithium), metal air batteries, redox flow batteries, and super-capacitors. Thermal storage comprises power-to-heat and heat-to-power technologies. Hydrogen can be stored under different forms (compressed gas, liquid), in saline underground cavities, or by using water electrolysis and fuel cells. The authors propose an overview of the different services provided by energy storage to the electricity system, and discuss the main perspectives and challenges for tomorrow's storage (electric mobility, integration of renewable energies, electrification of isolated areas, scenarios of development)

    International Nuclear Information System (INIS)

    1999-01-01

    Energy efficiency is the sum total of various influential factors resulting from the technical, technological, economic, financial, legislative and organisational conditions that exist in each of the transition countries. It is not possible to achieve an efficient usage of energy as in the Western European countries unless the total efficiency of managing all other resources equals the same level. Therefore, in the preceding period only the most successful companies managed to take considerable steps as regards the enhancement of energy efficiency, i.e. companies present at the European market and equalling the criteria of the their competitors. The problem of energy efficiency can be explained with the help pf a number of factors influencing decision making of a company's management or a citizen. Those factors create a framework of events, i.w. an appropriate or an inappropriate atmosphere for the implementation of the measures to increase energy efficiency. Attitudes for and against certain activities develop in an atmosphere according to which individuals have to make decisions. Non-economic prices, non-existence of tariff systems or systems with socially influenced prices or tariffs, have a demotivating effect on all the activities in the field of energy efficiency. The existing legislation of the transition countries often enough neglects the problem of energy management, relating to either building planning and construction, or network systems, renewable sources or consumption standards at the market. The financial situation is also an important element when dealing with energy efficiency projects; high interest rates and major problems with the insurance of necessary financial funds impede their realisation. The support of expert and consulting institutions is a precondition for a successful choice of measures, and the educational system should take over its extremely important role at each of the education levels. Energy efficiency programmes cannot be

    Directory of Open Access Journals (Sweden)

    Full Text Available The energy sector is pivotal to our aspirations for a sustainable planet and yet two major challenges face policymakers worldwide. The first is to decide what set of technical choices provide the best solution to meet social, economic and environmental agendas; and the second is to decide how these choices can be financed. The bulk of new energy demand will come from the emerging economies where energy demand is expected to increase by 40% over the coming three decades and to have doubled by the middle of the century. However for a number of reasons the investment needs of the energy sector are likely to rise even faster than overall energy demand. This is due to a number of factors over and above the increase in demand and described in the paper, including, inter alia, subsidized prices; the substitution of traditional energy for modern energy; the growth in peak demand in the electricity sector; the rising costs of securing primary energy resources; and the urgent need to replace vintage capital stock (including the decommissioning of nuclear power plants, especially in the developed countries. Clean energy investment will also incur high upfront investment costs in order to reduce long-term recurrent costs (fuel and maintenance. High priority must be given to energy demand management (both to reduce energy use and to reduce energy capital and investment in upgrading of existing capital stock can provide strong and quick returns. However, the net result of the long-term demand on the energy sector is that investment needs will grow dramatically, from around US $1.6 trillion per annum to over US $2 trillion per annum. The financial challenge is considerable. A level playing field is required that encourages greater competition of technology choice on the basis of correct pricing signals. It will require changes in subsidy policies in order to release finance and to encourage efficient investment; adherence to least-cost planning and investment

    2013-01-01

    This paper makes a case for examining energy transition as a geographical process, involving the reconfiguration of current patterns and scales of economic and social activity. The paper draws on a seminar series on the ‘Geographies of Energy Transition: security, climate, governance' hosted by the authors between 2009 and 2011, which initiated a dialogue between energy studies and the discipline of human geography. Focussing on the UK Government's policy for a low carbon transition, the paper provides a conceptual language with which to describe and assess the geographical implications of a transition towards low carbon energy. Six concepts are introduced and explained: location, landscape, territoriality, spatial differentiation, scaling, and spatial embeddedness. Examples illustrate how the geographies of a future low-carbon economy are not yet determined and that a range of divergent – and contending – potential geographical futures are in play. More attention to the spaces and places that transition to a low-carbon economy will produce can help better understand what living in a low-carbon economy will be like. It also provides a way to help evaluate the choices and pathways available. - Highlights: ► Examines transition as a geographical process, reconfiguring patterns and scales of activity. ► Provides concepts for assessing geographical implications of transition to a low-carbon economy. ► Outlines location, landscape, territoriality, uneven development, scaling, and embeddedness.

    The aim of the debate was to gain insight (highlights and gaps) in the Dutch approach to energy transition and to get a feel for the sense of urgency. The results of the internet debate address the problems and (Dutch) challenges as could be deduced from the contributions and reactions. We suggest that the following four topics are relevant to keep in mind when participating in co-ordinated activities in the Netherlands such as the 'transition platforms' as initiated by the Dutch ministries involved: (1) The definition of energy transition - transform the community from the bottom up; (2) The goal of energy transition - develop systems to replace systems; (3) The organisation of energy transition - articulate user requirements and conditions; (4) Energy transition systems thinking - direct support also at nascent business models.

    Boulanger, Vincent

    2015-01-01

    In this book the author comments and discusses the content, successes and failures, uncertainties and consequences of the new German energy policy, Energiewende. The objective is to reach 80 to 95 per cent of reduction of greenhouse gas emissions by 2050 while phasing out nuclear. The author denies some statements about this policy. Some say that coal will replace nuclear as in fact renewable electricity production more than compensates the reduction of nuclear electricity production. Others say that Germany will have to import French nuclear electricity as in fact France must import German electricity in case of peak consumptions. Others say that German electricity became more expensive: it's true but it is in fact compensated by much higher energy savings. Remaining issues are the financing of nuclear plant dismantling and of nuclear waste management, the organisation of a decentralised production network, and the passage to renewable energies in the heating and transport sectors

    The energy levels of the 1s{sup 2}, 1s2l and 1s3l states of helium-like iron Fe XXV have been calculated using two sets of configuration-interaction wavefunctions. One set of wavefunctions was generated using the fully relativistic GRASP code and the other was obtained using CIV3, in which relativistic effects are introduced using the Breit-Pauli approximation. For transitions from the ground state to the n=2 and 3 states and for transitions between the n=2 and 3 states, the calculated excitation energies obtained by these two independent methods are in very good agreement and there is good agreement between these results and recent theoretical and experimental results. However, there is considerable disagreement between the various excitation energies for the transitions among the n=2 and also among the n=3 states. The two sets of wavefunctions are also used to calculate the E1, E2, M1 and M2 transition probabilities between all of the 1s{sup 2}, 1s2l and 1s3l states of helium-like iron Fe XXV. The results from the two calculations are found to be similar and to compare very well with other recent results for {delta}n=1 or 2 transitions. For {delta}n=0 transitions the agreement is much less satisfactory; this is mainly due to differences in the excitation energies. (author)

    Cities concentrate populations, consumptions, levers of actions, and are places of various experiments for energy transition. This book aims at giving an overview of possible scenarios of development of renewable energies in urban context. It is based on interviews of actors of the energy, building and urban planning sectors by researchers in town planning, management, technology, political and economic sciences. The authors examine what would occur if large companies would manage entire quarters, if local authorities would supervise production and supply, if the State would take control of all fields of action again, or if consumer cooperatives would exchange energy and pool productions. In its different chapters, the book presents four scenarios of energy coordination in urban context by 2040, discuss energy transition in urban spaces, discuss the perspectives of evolution towards more autonomous cities and quarters from an energetic point of view, and discuss business models and urban energetic innovations

    The case of Buenos Aires (13 million inhabitants) exemplifies the evolution of energy supply and distribution in a developing metropolis characterized by the growth of consumption, spatial extension and social contrasts. After the 2001 economic and political crisis, the energy sectors underwent a major reorganization. For the city this meant growing state intervention in energy supply, private firms and the fixing of energy prices. The resulting evolution does not meet the criteria of energy transition as conceived in Europe, but it highlights the weight of the federal government upon a fragmented metropolis where local actors struggle to find their own spaces of action

    This motion for a resolution on energy transition proposes a framework which integrates energy management, the development of renewable energies in France, an adapted taxation, and a clear industrial project for future energies. This framework must lead to the introduction of five-year and constraining budgets of reduction of greenhouse gas emissions. Thus, the articles of this motion address various topics: definition of national objectives of reduction of emissions, renewal of buildings, implementation of a tool similar to the British Climate Change Act, implementation of a new energy governance, launching of large industrial projects, European integration of the energy market, importance of energy efficiency and of consumption management, a review of the subsidy system for renewable energies, pollution taxation and reform of the ETS, limitation of the share of nuclear energy, introduction of a carbon tax at the border of the EU, promotion of rail freight transport, and so on

    1997-01-01

    The Paper notes the importance of energy consumption in agglomerations (65-70% in the economies in transition) and of related emissions. It assesses the technical and cost-effective potential for a 40% and more decrease in urban energy intensities and SO 2 /NO x emissions by 2020, resulting from a systematic approach to urban as well as energy planning. Compared to approaches worldwide, urban energy renewal in the economies in transition appears, as its beginning, characterized by a traditional focus on existing technological supply sub-systems such as district heating and co-generation. The obstacles to a more systematic approach, including demand side management, are slow progress in urban and energy reforms and a lack of acquaintance with modern planning tools. International cooperation is incommensurate with the long-term challenge of s ustainable urban development . (author)

    2009-01-15

    The research task in the study was, firstly, to analyse citizens' perceptions of the power structure underlying Finnish energy policy-making. Secondly, we analysed the role of civil society in the energy sector, addressing the question whether Finns feel that they can influence energy policy-making as citizens through general elections (civic participation) or as consumers via their own consumption choices (political consumerism). Methodologically, the study was based on postal survey conducted in 2007 among a random sample representing 18-75-year-old Finns (N=4000). According to the views expressed, the innermost core of the influence structure of Finland's energy policy-making today comprises only the Cabinet and Parliament, while the second circle is composed of energy-producer firms and big firms. The European Union, the Ministry of the Environment and the Ministry of Trade and Industry belong to the third circle of influence. The power relations in Finland's energy sector have continued particularly stable since the late 1980s despite the liberalization and globalization of the energy markets. In order to influence energy policy-making, citizens consider their own consumption choices more useful than voting in elections or contacts with MPs, authorities and energy-producing companies. The least useful devices are radical environmental activism and participation in mass demonstrations. (author)

  18. Energy Transition in the Nebular City: Connecting Transition Thinking, Metabolism Studies, and Urban Design

    Directory of Open Access Journals (Sweden)

    2018-03-01

    Full Text Available Transforming urban infrastructures is an essential part of creating more sustainable urban regions. But rethinking these complex systems requires a better understanding of their spatial dimensions and their relation with urban morphology and spatial structure. This paper addresses that gap by examining different conceptualizations of technical infrastructure and space in science, technology and society studies (STS, transition thinking, urban metabolism studies, and urban political ecology, and draws connections with the spatial perspective of urban planning and design. It illustrates and tests these concepts through the case of energy transition in the Flemish region of Belgium. Transport and supply networks have played a crucial role in facilitating, structuring, and reproducing the region’s characteristic dispersed and energy-intensive urban landscape. Bringing different disciplinary perspectives together, the research broadens the conceptualization of the spatial dimension in transition thinking, and identifies useful concepts and design parameters for urban design to engage with the technical and socio-political complexity of transforming urban infrastructure. It reveals the energy transition as an inherently spatial project, and explores the spatially and socio-politically transformative potential of the transition towards a new energy system.

  19. Ideal glass transitions in thin films: An energy landscape perspective

    Science.gov (United States)

    Truskett, Thomas M.; Ganesan, Venkat

    2003-07-01

    We introduce a mean-field model for the potential energy landscape of a thin fluid film confined between parallel substrates. The model predicts how the number of accessible basins on the energy landscape and, consequently, the film's ideal glass transition temperature depend on bulk pressure, film thickness, and the strength of the fluid-fluid and fluid-substrate interactions. The predictions are in qualitative agreement with the experimental trends for the kinetic glass transition temperature of thin films, suggesting the utility of landscape-based approaches for studying the behavior of confined fluids.

    To realize the energy transition in the building sector, three types of obstacles have to be overcome: technology-related, process-related and integration of technology and process. To this end an innovation / implementation program has been set up. The intrinsic driver of the program is the realization of increasingly more ambitious energy concepts in three successive waves, allowing for the different actors to learn from the previous wave, to prepare for the next wave and to scale up these type of projects both in terms of quantity and quality. The establishment process of the program identified a key success factor for the transition process itself: the role of the individual.

    Ruggiero, Salvatore; Varho, Vilja; Rikkonen, Pasi

    2015-01-01

    Small-scale distributed energy generation is expected to play an important role in helping Finland increase its energy self-sufficiency. However, the overall strategy to date for promoting distributed energy remains unclear. It is not yet well understood which factors promote the growth of the distributed energy sector and what barriers need to be removed. In this article we present the results of a questionnaire directed at a panel of 26 experts from the distributed energy value chain and 15 semi-structured interviews with industry and non-industry representatives. We investigated, from a sociotechnical transition perspective, the possibilities and challenges of the transition to distributed energy in Finland through 2025. The results show that a shift to a prosperous future for distributed energy is possible if permit procedures, ease of grid connection, and taxation laws are improved in the electricity sector and new business concepts are introduced in the heat sector. In contrast to other European countries, the transition in Finland is expected to take place through a market-based approach favoring investment-focused measures. We conclude that incentive-based schemes alone, whatever they may be, will be insufficient to create significant growth in Finland without institutional change, removal of barriers, and the engagement of key actors. - Highlights: • We examine the possibilities and challenges of the transition to DE in Finland. • Technological niches are emerging both in the heat and electricity sector. • Business model innovation is evident only in the electricity sector. • Removing barriers and developing new business models will accelerate the transition.

  4. Electric grids and energy transition in Europe

    2015-06-01

    Focussing on electricity, this report proposes an analysis of the main elements in favour of large investments in electric grids, while notably outlining technical or economic uncertainties as well as possible political consequences such as compatibility of a largely interconnected European network with a free choice of energy sources (as specified in the Lisbon Treaty), and responsibility for the States in terms of supply security. The author first describes the present situation: overview of the regulatory framework of the liberalization process. The second part addresses challenges which emerged with the European commitment in favour of renewable sources of electricity and the emergence of new needs, notably regarding electric vehicles. It also presents measures aimed at supporting the development of networks. The third part introduces a discussion about the relevancy of this development by highlighting, on the one hand, the fragility of economic perspectives, and on the other hand, the necessity to address future consequences of a major increase of interconnections within the European electric grid. Some recommendations are finally proposed. Examples and specific analysis more particularly concern Germany, Spain, France, Italy and the United-Kingdom

  6. 15 signals evidence the energy transition is underway

    International Nuclear Information System (INIS)

    2016-09-01

    World leaders approved a universal climate agreement in Paris last year, drawing a line in the sand for the transformation of the world's energy system into a clean and sustainable form. Signs that a global energy transition is happening are everywhere to be seen: in the growth of renewables, the rise of city-level climate actions, the stagnation of CO 2 emissions and in companies who are committing to science based targets as the foundation of their climate actions, to name just a few. We felt it important to highlight 15 key signs or 'signals' of the energy transition, to help raise awareness that the transition to a new, sustainable, equitable, just and fair global energy system has irrevocably begun. What is needed now is to accelerate the transition and scale it up to have a chance of keeping global temperature rise to well below 2 deg. C, trying for 1.5 deg. C, as countries committed to in the Paris Agreement just eight months ago. Global meetings such as the G20 meeting taking place in China on 4-5 September; and the next UN climate talks starting in Marrakech on 7 November gives opportunity to all stakeholders to say how and what they can contribute to accelerating the transition. Ending fossil fuel subsidies, supporting the deployment of renewables and energy efficiency, increasing green finance and putting a just price on carbon are just some of the actions that can be taken right now to put pace into the transition. As 2016 heads into the record books as likely the hottest year ever recorded in history, it is a reminder that we have precious little time left to act to keep global temperatures well below 2 deg. C. We have the Paris Agreement to guide our way. Now we need to implement it. Now is the time for action

    2017-01-01

    Direct Energie, a major player in France and Belgium, has compelled recognition as a well-balanced operator in the production and supply of electricity and natural gas. Having made innovation one of the major axes of its development, this firm is using digital technology for the energy transition and in response to consumer needs. Direct Energie, a supplier of 'energy 4.0', is seeking to position itself as a leader in 'orchestrating' the consumption of energy by its customers. Given this strong position as the single supplier of energy to its customers, the regulatory framework for data transmission must be reviewed to make it compatible with the 'single contract', which binds a customer to a firm that both supplies and transports energy

    Gay, Michel

    2013-01-01

    In this conference, the author discusses the objectives of energy transition in France, and the objectives of the debate on this issue, and addresses three important questions raised by this issue: how to move towards energy efficiency and energy sobriety, which pathway to reach the targeted energy mix in 2025, which are the costs, benefits and financing of energy transition. He describes the complexity of the problem and its contradictory aspects (how to produce more energy with less oil, gas and coal). As far as the first question is concerned (energy efficiency and sobriety), he discusses the notion of energy sobriety, what is at stake (supply security, economic, social and climatic challenges), the strategic objectives, the evolution of energy consumption and production, the leading role of electricity, the CO 2 emissions by different economic sectors, the level of energy imports, the issue of electricity price. As far as the two other questions are concerned, he discusses the opportunities associated with the building and transport sectors, the issue of energy storage, and the role of EDF. In a second part, the author criticizes the Negawatt scenario, and the ADEME's position and action, and discusses opportunities related to energy efficiency, the decrease of the use of fossil energy, the promotion of electricity, and the preservation of nuclear energy as a French asset. He comments the statements of French political actors, the evolution of wind energy production in Europe, the low level of energy and electricity production by the French wind turbines. He discusses a comparison between coal and nuclear in terms of production and pollution, the issue of nuclear waste management, the perspectives for nuclear reactors, the situation in other countries (Switzerland, Germany). He notably outlines that phasing out nuclear in Germany results in the use of coal plants and gas imports

    2017-01-01

    Digitalization is becoming ubiquitous in the energy sector, enabling a more decentralized energy system and blurring the traditional energy sector boundaries, with more integration with buildings, mobility solutions and industry. Digitalization is accelerating the pace of the energy transition, mainly thanks to three levers: 1) enhancing customer interaction with the energy system, 2) optimizing operations, and 3) enabling new business models for traditional energy actors as well as opening up space for new entrants from other sectors and energy start-ups. Digital technologies are also facilitating a cost-effective, clean energy transition, mainly by increasing energy efficiency and flexibility, as well as enabling the integration of renewable electricity into smart(er) grids and developing low-carbon solutions. This article gives a brief overview of the digitally-enabled innovations in Europe's energy markets and how various players are positioning themselves to take advantage of these opportunities. It concludes by highlighting some of the policy issues this transformation raises and the challenges ahead for European businesses to reap the benefits

The ways how public has participated in the making of a few officially accepted documents have been analysed and potential benefits of inclusion of a wider circle of interested public have been stated. A comparison of the degree of public involvement in the decision making processes in Croatia and the European Union has been made, with specific emphasis on the adoption of the Third package of energy laws. Several national and EU funded projects aiming at enhancing the Croatian public participation in public decision making processes have been presented and their results given. Finally, possibilities for the improvement of the public participation in the Croatian energy policy making processes are proposed. (author)

    Spurred by innovation, increased competition, and policy support in a growing number of countries, renewable energy technologies have achieved massive technological advances and sharp cost reductions. Renewables have come to the forefront of the global energy transition, with nearly every country adopting a renewable energy target. Yet progress has been uneven in different countries and sectors. Technology and financial risks still hamper the expansion of renewables into new markets. As the power sector develops further, the increased adoption of variable renewables like solar and wind requires more flexible systems. Compared to power generation, the regulatory framework for end-use sectors lags behind. This report, prepared jointly by the International Renewable Energy Agency (IRENA), the International Energy Agency (IEA) and the Renewable Energy Policy Network for the 21. Century (REN21), identifies key barriers and highlights policy options to boost renewable energy deployment. After reviewing current policies and targets worldwide, it examines sector-specific policies for heating and cooling, transport and power, as well as measures for integrating variable renewables. An updated policy classification and terminology list can serve as a global reference for renewable energy policy instruments. Among the key findings: Renewable energy policies must focus on end-use sectors, not just power generation; The use of renewables for heating and cooling requires greater policy attention, including dedicated targets, technology mandates, financial incentives, generation-based incentives, and carbon or energy taxes; Policies in the transport sector require further development, including integrated policies to de-carbonise energy carriers and fuels, vehicles and infrastructure; Policies in the power sector must also evolve further to address new challenges. Measures are needed to support the integration of variable renewable energy, taking into account the specific

  18. Global Energy Transitions and the Challenge of Climate Change

    2008-01-01

    Global emissions of greenhouse-gases have increased markedly as a result of human activities since pre-industrial times. This increase in emissions has lead to unequivocal global warming, which is evident from observations of increases in global average air and ocean temperatures, widespread melting of snow and ice, and rising global average sea level. Reducing the risk of irreversible climate impacts requires thus the mitigation of global GHG emissions aiming at the long-term stabilization of atmospheric GHG concentrations. Achieving this goal translates into the need of reducing emissions to virtually zero over long time-frames. Yet international agreement on a long-term climate policy target remains a distant prospect, due to both scientific uncertainty and political disagreement on the appropriate balance between mitigation costs and reduced risks of dangerous impacts. At the same time, growing emissions of greenhouse gases continue to increase the amount of climate change we are committed to over the long term. Over the next few decades, these growing emissions may make some potentially desirable long term goals unattainable. Recent analysis conducted at IIASA indicates the need of major energy transitions over the next few decades. For example, staying below the target suggested by the European Union of 2 C warming (with just a 50% likelihood) will require the massive deployment of zero-carbon energy by 2050, and a tippling of the contribution of zero-carbon energy globally to more than 60% by that time. Although there are large uncertainties with respect to the deployment of individual future technologies, there is strong evidence that no single mitigation measure alone would be sufficient for achieving the stabilization of GHG concentrations at low levels. A wide portfolio of technologies across all GHG-intensive sectors is needed for cost-effective emissions reductions. The bulk of these emissions reductions would need to come from the energy sector, with

    2017-01-01

    This paper focusses on investigating the underlying mechanisms and influences of the policy decision making process and how it affects and impacts the governance of the Nigerian energy industry, and energy infrastructure provisions. In-depth semi-structured interviews were used; all interviewees had been involved, directly or indirectly, in energy infrastructure policy decisions in Nigeria. Five key themes subsequently emerged as salient intra-country induced influences that were affecting the governance and performance of the Nigerian energy sector: (1) competencies – i.e. practical knowledge of energy policy making; (2) expectations – i.e. past, present, and forecasted future expectations from the energy industry; (3) legislation – i.e. institutionalized (and unwritten) rules/procedures; (4) future visions – i.e. future vision of the energy industry/energy market; (5) recruiting experts – i.e. recruiting new energy and public policy makers. In addition, three major inter-country induced influences were also identified: (1) the changing dynamics of international and foreign aid; (2) the United Nations Sustainable Development Goals; and (3) the Paris Agreements on Climate Change. The paper concludes by highlighting the policy implications of these influences, and the consequences for policy makers in the governance of the energy industry in ensuring a secured energy future. - Highlights: • Unclear energy policies pose a business risk to current and future investors. • Our energy future is threatened by unsystematic recruitment into the policy space. • Some energy governance challenges reflect incompetence in energy legislation. • Nigerian energy transition was shaped by historical policy dynamics and structures.

    Full Text Available Mainstream approaches to energy democracy and public engagement with energy transitions tend to adopt specific, pre-given meanings of both “democracy” and “publics.” Different approaches impose prescriptive assumptions about the model of participation, the identity of public participants, and what it means to participate well. The rigidity of many existing approaches to energy participation is increasingly being challenged by the ever-multiplying diversity of ways in which citizens participate in energy systems, as consumers in energy markets, protesters against new infrastructures and technologies, as initiators of community energy projects, and as subjects of behavior change interventions, amongst others. This paper is concerned with growing areas of scholarship which seek to understand and explore these emerging energy publics and forms of energy democracy from a relational perspective. Such work, grounded in constructivist and relational ontologies, views forms of participatory democracy and publics as being co-produced, constructed, and emergent through the performance of collective practices. It pays closer attention to power relations, politics, materiality, exclusions, and effects in both understanding and intervening in the making of energy democracy. This in turn shifts the focus from studying discrete unitary forms of “energy democracy” to one of understanding interrelations between multiple diverse energy democracies in wider systems. In this paper, we chart these developments and explore the significant challenges and potential contributions of relational approaches to furthering the theories, methods, and practices of energy democracy and energy public engagement. The paper draws on an expert workshop, and an accompanying review, which brought together leading proponents of contending relational approaches to energy participation in direct conversation for the first time. We use this as a basis to explore tensions

    It is possible that metal-dielectric transition does not result in changes of magnetic or crystallographic symmetry. In this case a fermionic spectrum is not changed at the transition, but additional low-energy excitations appear which can be described as a gauge field that has the same symmetry as an electromagnetic one. In the case of a non half-filled band gapless scalar Bose excitations also appear. Due to the presence of additional gauge field the physical conductivity is determined by the lowest conductivity of the Fermi or Bose subsystems. (author). 11 refs

    Transitions are societal transformation processes that occur in at least one generation (i.e. 25 years). Transitions are structural changes of the society or a complex part of that society. Transitions show technological, economical, ecological, socio-cultural and institutional developments on different levels. A transition is the result of slow changes (developments in supplies) and fast dynamics (flows). In general, four transition phases can be distinguished: (1) a pre-development phase of dynamic equilibrium in which the status quo does not change much; (2) a take-off phase in which the process of change is started; (3) an acceleration phase in which structural changes occur, resulting in collective learning processes, diffusion and processes of implementation; (4) a stabilization phase in which the speed of societal changes decreases and a new dynamic equilibrium exists. Within the framework of the preparatory process of the Fourth Dutch National Environmental Plan (NMP4) a study has been carried out to explore the transition concept, focusing on an emission-low energy supply in the Netherlands. 49 refs

  7. Observation on optimal transition from conventional energy with resource constraints to advanced energy with virtually unlimited resource

    International Nuclear Information System (INIS)

    Suzuki, Atsuyuki

    1980-01-01

    The paper is aimed at making a theoretical analysis on optimal shift from finite energy resources like presently used oil toward advanced energy sources like nuclear and solar. First, the value of conventional energy as a finite resource is derived based on the variational principle. Second, a simplified model on macroeconomy is used to obtain and optimal relationship between energy production and consumption and thereby the optimality on energy price is provided. Third, the meaning of research and development of advanced energy is shown by taking into account resource constraints and technological progress. Finally, an optimal timing of the shift from conventional to advanced energies is determined by making use of the maximum principle. The methematical model employed there is much simplified but can be used to conclude that in order to make an optimal shift some policy-oriented decision must be made prior to when an economically competitive condition comes and that, even with that decision made, some recession of energy demand is inevitable during the transitional phase.

    The simultaneous implementation of the German 'Energiewende' and the French 'Transition energetique' prompted both country's governments to sign various cooperation agreements. As both 'Energiewende' and 'Transition energetique' put a strong focus on decentralization of energy supply, establishing close inter-communal cooperation is particularly promising. The project TANDEM, which is jointly led by Klima-Buendnis and Energy Cities - both local authority networks - and co-funded by Germany's Federal Environment Agency (UBA) and the French Energy Agency ADEME provides French and German local authorities with a unique opportunity to exchange experiences and create partnerships for climate protection having the following objectives: - Creating broad mutual understanding for the respective situation, challenges and framework in energy and climate policy; - Encourage exchanges with regard to obstacles and success factors concerning the realization of ambitious energy- and climate-goals and promoting mutual transfer of know-how; - Stimulating close collaboration between local authorities from both countries while involving and supporting local stakeholders and citizens; - Implementing initial stages of cooperation projects during the lifetime of the TANDEM project and creating a foundation for long-term cooperation; - Raise awareness for demands, requirements and concerns of local authorities on a national and European level in order to strengthen their influence and enlarge their scope of action. In this document, the authors briefly present the French, German and European contexts and the organization of both countries regarding energy transition. Then, a parallel is made between the national energy-climate plans of both countries ('Klimaschutzkonzepte' and 'Plans Climat-Energie Territoriaux') to identify the similarities and differences in order to learn from each other and to be able to create cooperations between both policy mechanisms

    This document gathers several articles from different countries on different topics related to energy transition. The first part deals with the challenge of energy efficiency as a mean on the way to energy transition (in France, in Europe, in Latin America, in Asian developing countries). The second part illustrates through examples the importance of governance issues and political will (access to energy in West Africa, a network in Latin America and the Caribbean, use of LEDs for public lighting in Brazil, Tunisian policy, role of regulation authorities, situation in India). The third part proposes examples illustrating the importance of the local dimension in any policy aimed at energy efficiency (a project in Africa, public support in housing construction in Austin, the Swedish city of Vaxjo, the French city of Montdidier, the example of two quarters of Geneva using the lake water as cooling or heating source, the refrigerator fleet in a Palestinian village). The last part reports several experiments made in different sectors (building thermal rehabilitation in China, green buildings in India, the building sector in India, a new strategy in India for domestic and commercial electric equipment, stimulation of energy efficiency in the Japanese industry, public transport in sub-Saharan cities, energy efficiency in Indian agriculture)

    Ecological transition is a concrete and progressive measure, to be committed to here and now, aimed at better taking environmental challenges into account, with a strong regional dimension. The 4 main environmental challenges are attenuation and adaptation to climate change, the preservation of biodiversity, access to raw materials and the protection of human health. This approach is within the context of sustainable development. It implies a profound change from our current development model. Energy transition is one of the strands of ecological transition. Certain examples from abroad are worth bearing in mind in the field of energy transition (Germany, the United Kingdom), or the scope of stimulus packages aimed at ecological transition (South Korea). Ecological transition has a cost: collective anticipation. In France, available financing tools are above all those of traditional environmental policies, some of which benefit from dedicated financing. Other public policies integrate the challenges of ecological transition in a diverse manner, and mostly very poorly. As for the private financing of this transition, this depends firstly on the profitability of the economic framework, which is still far from optimal. It also depends on taking extra-financial criteria into account, something which is still very weak. To implement ecological transition, room for manoeuvre needs to be created in a constrained financial context: weakening growth, public expenditure contingencies, and difficulties in deploying private saving. To properly meet economic and social challenges, ecological transition must contribute to the economic dynamism of regions, facing the challenge of 'sustainable competitiveness'. To achieve this we need to identify the uncertainties which hinder the proactive approach of key stakeholders, to better articulate the various decision-making levels and improve the resilience of regional economies. The mobilisation of civil society is a key

  14. Decision making in energy policies with conflicting interests

    After the accident in Chernobyl policy making and implementation of energy decisions have become more difficult than ever. On the one hand the public reacts with fear and opposition to a possible extention of nuclear power, on the other hand the economic prosperity of a country depends on an inexpensive and non-exhaustive energy source like nuclear energy. The paper describes a concept of energy planning developed by a study group of the Nuclear Research Centre in Julich (FRG). The concept is based on the idea that in a pluralistic society different social groups should participate in the policy formulation process and that the values of the public should be incorporated in the weighting process to make choices between given options. As reference theory the basic framework of decision analysis is used. (orig./DG)

  15. Energy Transition: Missed Opportunities and Emerging Challenges for Landscape Planning and Designing

    Directory of Open Access Journals (Sweden)

    2014-07-01

    Full Text Available Making the shift from fossil fuels to renewable energy seems inevitable. Because energy transition poses new challenges and opportunities to the discipline of landscape architecture, the questions addressed in this paper are: (1 what landscape architects can learn from successful energy transitions in Güssing, Jühnde and Samsø; and (2 to what extent landscape architecture (or other spatial disciplines contributed to energy transition in the aforementioned cases. An exploratory, comparative case study was conducted to identify differences and similarities among the cases, to answer the research questions, and to formulate recommendations for further research and practice. The comparison indicated that the realized renewable energy systems are context-dependent and, therefore, specifically designed to meet the respective energy demand, making use of the available potentials for renewable energy generation and efficiency. Further success factors seemed to be the presence of (local frontrunners and a certain degree of citizen participation. The relatively smooth implementation of renewable energy technologies in Jühnde and on Samsø may indicate the importance of careful and (partly institutionalized consideration of landscape impact, siting and design. Comparing the cases against the literature demonstrated that landscape architects were not as involved as they, theoretically, could have been. However, particularly when the aim is sustainable development, rather than “merely” renewable energy provision, the integrative concept of “sustainable energy landscapes” can be the arena where landscape architecture and other disciplines meet to pursue global sustainability goals, while empowering local communities and safeguarding landscape quality.

    As the primary objective of any energy policy is now to reduce carbon dioxide emissions, i.e. to reduce the consumption of all carbonated fuels (coal, oil, gas) in all sectors, and to substitute them with electricity produced from nuclear and renewable sources, and all this under a double constraint (that of consumers, and that of public finances), this article aims at discussing whether the French policy defined by the law on energy transition for a green growth is able to face and meet these priorities. The author outlines that the struggle against greenhouse gas emissions in France mainly concerns the transport and heating sectors. He discusses drawbacks associated with a transition mainly focussed on electric power generation by wind and solar energy: these drawbacks concern the required and actual production level, necessary high investments, and the protection of the environment. He proposes four areas of development for a successful transition: electric transport, energy storage, power-to-gas conversion, and housing thermal insulation

    Current energy distribution networks are often not equipped for facilitating expected sustainable transitions. Major concerns for future electricity networks are the possibility of peak load increases and the expected growth of decentralized energy generation. In this article, we focus on peak load increases; the effects of possible future developments on peak loads are studied, together with the consequences for the network. The city of Eindhoven (the Netherlands) is used as reference city, for which a scenario is developed in which the assumed future developments adversely influence the maximum peak loads on the network. In this scenario, the total electricity peak load in Eindhoven is expected to increase from 198 MVA in 2009 to 591-633 MVA in 2040. The necessary investments for facilitating the expected increased peak loads are estimated at 305-375 million Euros. Based upon these projections, it is advocated that - contrary to current Dutch policy - choices regarding sustainable transitions should be made from the viewpoint of integral energy systems, evaluating economic implications of changes to generation, grid development, and consumption. Recently applied and finished policies on energy demand reduction showed to be effective; however, additional and connecting policies on energy generation and distribution should be considered on short term. - Highlights: > Sustainable energy transitions can result in major electricity peak load increases. > Introduction of heat pumps and electrical vehicles requires network expansion. > Under worst case assumptions, peak loads in Eindhoven increase with 200% until 2040. > The necessary investment for facilitating this 2040 peak demand is Euro 305-375 million. > Future policy choices should be made from the viewpoint of the integral energy system.

  2. Conformational Transitions and Convergence of Absolute Binding Free Energy Calculations

    The Binding Energy Distribution Analysis Method (BEDAM) is employed to compute the standard binding free energies of a series of ligands to a FK506 binding protein (FKBP12) with implicit solvation. Binding free energy estimates are in reasonably good agreement with experimental affinities. The conformations of the complexes identified by the simulations are in good agreement with crystallographic data, which was not used to restrain ligand orientations. The BEDAM method is based on λ -hopping Hamiltonian parallel Replica Exchange (HREM) molecular dynamics conformational sampling, the OPLS-AA/AGBNP2 effective potential, and multi-state free energy estimators (MBAR). Achieving converged and accurate results depends on all of these elements of the calculation. Convergence of the binding free energy is tied to the level of convergence of binding energy distributions at critical intermediate states where bound and unbound states are at equilibrium, and where the rate of binding/unbinding conformational transitions is maximal. This finding mirrors similar observations in the context of order/disorder transitions as for example in protein folding. Insights concerning the physical mechanism of ligand binding and unbinding are obtained. Convergence for the largest FK506 ligand is achieved only after imposing strict conformational restraints, which however require accurate prior structural knowledge of the structure of the complex. The analytical AGBNP2 model is found to underestimate the magnitude of the hydrophobic driving force towards binding in these systems characterized by loosely packed protein-ligand binding interfaces. Rescoring of the binding energies using a numerical surface area model corrects this deficiency. This study illustrates the complex interplay between energy models, exploration of conformational space, and free energy estimators needed to obtain robust estimates from binding free energy calculations.

  3. Simple solvable energy-landscape model that shows a thermodynamic phase transition and a glass transition.

    2012-06-01

    When a liquid melt is cooled, a glass or phase transition can be obtained depending on the cooling rate. Yet, this behavior has not been clearly captured in energy-landscape models. Here, a model is provided in which two key ingredients are considered in the landscape, metastable states and their multiplicity. Metastable states are considered as in two level system models. However, their multiplicity and topology allows a phase transition in the thermodynamic limit for slow cooling, while a transition to the glass is obtained for fast cooling. By solving the corresponding master equation, the minimal speed of cooling required to produce the glass is obtained as a function of the distribution of metastable states.

  5. Cohesion and coordination effects on transition metal surface energies

    Science.gov (United States)

    Ruvireta, Judit; Vega, Lorena; Viñes, Francesc

    2017-10-01

    Here we explore the accuracy of Stefan equation and broken-bond model semiempirical approaches to obtain surface energies on transition metals. Cohesive factors are accounted for either via the vaporization enthalpies, as proposed in Stefan equation, or via cohesive energies, as employed in the broken-bond model. Coordination effects are considered including the saturation degree, as suggested in Stefan equation, employing Coordination Numbers (CN), or as the ratio of broken bonds, according to the bond-cutting model, considering as well the square root dependency of the bond strength on CN. Further, generalized coordination numbers CN bar are contemplated as well, exploring a total number of 12 semiempirical formulations on the three most densely packed surfaces of 3d, 4d, and 5d Transition Metals (TMs) displaying face-centered cubic (fcc), body-centered cubic (bcc), or hexagonal close-packed (hcp) crystallographic structures. Estimates are compared to available experimental surface energies obtained extrapolated to zero temperature. Results reveal that Stefan formula cohesive and coordination dependencies are only qualitative suited, but unadvised for quantitative discussion, as surface energies are highly overestimated, favoring in addition the stability of under-coordinated surfaces. Broken-bond cohesion and coordination dependencies are a suited basis for quantitative comparison, where square-root dependencies on CN to account for bond weakening are sensibly worse. An analysis using Wulff shaped averaged surface energies suggests the employment of broken-bond model using CN to gain surface energies for TMs, likely applicable to other metals.

    Illustrated by more than 120 maps and figures, this book proposes an overview of the world nuclear industry, of its development, and of the various strategies chosen within the perspective of energy transition. It proposes an overview of the status of nuclear energy in the world (presentation of the nuclear energy, development during the X X century, uranium production, fuel production and processing, the nuclear reactor industry), addresses the main controversies (health and environmental impact, waste management, opacity of the information, major accidents), the new challenges faced by the nuclear sector (a difficult assessment of huge costs, competition with renewable energies, a competitive environment, a technological uncertainty, transparency and democracy), the solutions chosen by big countries (USA, China, India, Japan, Europe, the German energy transition), and proposes a focus on France which is the only country which chose an all-nuclear strategy (history, nuclear installations, main actors, the myth of the French energy independence, the post-Fukushima French fleet, the case of the Fessenheim reactor, the EPR in question, the challenge of waste storage with the Cigeo project, the debate on the nuclear cost)

    Very little work has been done so far to model, test, and understand the relationship between oil prices and EROI over time. This paper investigates whether a declining EROI is associated with an increasing oil price and speculates on the implications of these results on oil policy. A model of the relationship between EROI and oil market prices was developed using basic economic and physical assumptions and non-linear least-squares regression models to correlate oil production price with EROI using available data from 1954–1996. The model accurately reflects historical oil prices (1954–1996), and it correlates well with historical oil prices (1997–2010) if a linear extrapolation of EROI decline is assumed. As EROI declines below 10, highly non-linear oil price movements are observed. Increasing physical oil scarcity is already providing market signals that would stimulate a transition away from oil toward alternative energy sources. But, price signals of physical oil scarcity are not sufficient to guarantee smooth transitions to alternative fuel sources, especially when there is insufficient oil extraction technology development, a declining mark-up ratio, a non-linear EROI–cost of production relationship, and a non-linear EROI–price relationship. - Highlights: ► A model of the relationship between EROI and oil prices has been developed. ► As EROI declines below 10, highly non-linear oil price movements are expected. ► Physical oil scarcity provides market signals for a transition to alternatives. ► Scarcity price signals are insufficient for smooth transitions to alternatives.

    After a brief review of the decisive contribution of the R and D and the innovation (RDI) to the economic growth and thus to the employment and also as a main driver of energy transition in Europe, a focus will be brought in how RDI choices are made, especially in companies, with the consequences on the business organization. Focusing on the conditions of the deployment and the dissemination of innovations, the key role of the demonstration will be examined as well as the learnings to promote the emergence of new technologies, particularly those serving the energy transition. In conclusion, we will discuss how the research and innovation policies are being addressed, in particular their connection with corporate strategies and industrial policies? All along the presentation, several examples of different technologies will be given, in order to provide illustrations of the potential developments, the possible breakthroughs, bottlenecks and cost etc.(author).

    2010-01-01

    The study of the hydrodynamics of bubble growth in first-order phase transitions is very relevant for electroweak baryogenesis, as the baryon asymmetry depends sensitively on the bubble wall velocity, and also for predicting the size of the gravity wave signal resulting from bubble collisions, which depends on both the bubble wall velocity and the plasma fluid velocity. We perform such study in different bubble expansion regimes, namely deflagrations, detonations, hybrids (steady states) and runaway solutions (accelerating wall), without relying on a specific particle physics model. We compute the efficiency of the transfer of vacuum energy to the bubble wall and the plasma in all regimes. We clarify the condition determining the runaway regime and stress that in most models of strong first-order phase transitions this will modify expectations for the gravity wave signal. Indeed, in this case, most of the kinetic energy is concentrated in the wall and almost no turbulent fluid motions are expected since the s...

    Current government information policies and market-based instruments aimed at influencing the energy choices of consumers often ignore the fact that consumer behaviour is not fully reducible to individuals making rational conscious decisions all the time. The decisions of consumers are largely configured by shared routines embedded in socio-technical systems. To achieve a transition towards a decarbonized and energy-efficient system, an approach that goes beyond individual consumer choice and puts shared routines and system change at its centre is needed. Here, adopting a transitions perspective, we argue that consumers should be reconceptualized as users who are important stakeholders in the innovation process shaping new routines and enacting system change. We review the role of users in shifts to new decarbonized and energy-efficient systems and provide a typology of user roles.

  13. Energy and population: transitional issues and eventual limits.

    Science.gov (United States)

    Werbos, P J

    1990-08-01

    The implication of population size for US energy requirements is explored in this essay. The basic argument is that the present supply of fuels and energy technologies is not sustainable in the long run, that a wide range of choices is possible when a complete transition is made to sustainable technologies, and that the growth of population and the composition of this growth during the next 30 years are the most serious problems impacting on the achievement of sustainable technology. The importance and future of fuel oil is discussed as well as the transition to sustainable energy supplies: conservation, renewables, nuclear and coal. Dependency on oil can only be changed through time and the infusion of money, but even with these givens, the transition is also dependent on the political and budgetary climate. The race is between crisis and cure. It is argued that the soft energy systems (biomass, solar water heater, wind, hydro, and geothermal energy) along with conservation will increase easily and naturally, but the total potential from these sources amounts to only 10% of the present US energy supply. Conservation offers greater hope because 80% of end-use fossil fuel is used in transportation and industry. Further growth of the population in the US would create a demand to desalinate water, which would increase the demand for energy. A totally soft energy economy is probably not feasible without a drastic reduction in US population. The expected direction is in the increased use of coal, and then nuclear energy. Unfortunately, coal contributes to greenhouse warming, and the supply is limited to 60-100 years. Nuclear proliferation and terrorism is connected to the widespread use of nuclear energy. Some breakthrough technology with cold fusion may offer a safer alternative. High technology renewables such as solar cells can be competitive with nuclear energy, if prices can be kept down. on earth or in space, are being investigated. Exploring a variety of advanced

    France's national debate on energy transition has served as a reminder that hydroelectric power plays a significant role in French electricity production. With installed power totalling 25400 MW at end 2012 (the second largest in Europe), France's hydroelectric plants produced 63.8 TWh last year (the third largest in Europe), almost 12% of total output. It is France's second largest means of producing electricity and it represents more than 80% of production of renewable energy. A source of energy developed a long time ago, thus benefiting from technological maturity, hydroelectricity can be produced in large quantity at the heart of France's regions, while also rendering indispensable service for the equilibrium of the French electricity system by compensating the intermittency of other renewable energy sources. The production costs of hydroelectric power are the lowest among all power generation technologies. (authors)

    Mathieu, Mathilde

    2013-01-01

    This thesis aims at seeing how an analysis of national scenarios of energy transition may contribute to the elaboration of European energy and climate policies. The author first identifies the characteristics of energy scenarios, and the relationship between a scenario considered as an object on the one hand, and a vision for the long term on the other hand. She proposes an analysis framework which enables a comparative analysis of scenarios in order to identify stakes and challenges for the future European policy. In the second part, the author presents three examples (Germany, United Kingdom and France) and discusses their political context and adopted scenarios. After an overview of existing European energy and climate policies, the results of the analysis are given for two specific sectors: transports and electricity

  16. Energy transitions in France: lessons learned from prospective studies. Contribution to the National Debate on Energy Transition

    2013-01-01

    After having outlined that the debates on energy transition in France focus on three main issues (management of greenhouse gas emissions, future of nuclear within the French energy mix, energy security), the authors report the use of the Imaclim-R France model (a multi-sector recursive hybrid model) which is adapted to sensitivity studies for the whole set of hypotheses. As energy parameters, they use data provided by ENCILOWCARB scenarios from a European project (Engaging civil society in low carbon scenarios). After having examined that they are not sufficient to conduct a transition strategy leading to a F4 pathway of reduction of greenhouse gas emissions and/or a progressive phasing out nuclear, they consider the policies which are necessary to mobilise potentials of energy saving and emission reduction. Several scenarios are studied in terms of energy and environmental performances and in terms of economic and social performances: scenarios based on policies and measures with or without additional component (carbon tax, social negotiation, carbon finance)

    We investigate the origin of the difference, which was noticed by Fey et al. [Phys. Rev. Lett. 104, 145703 (2010), 10.1103/PhysRevLett.104.145703], between the steady state density of an Abelian sandpile model (ASM) and the transition point of its corresponding deterministic fixed-energy sandpile model (DFES). Being deterministic, the configuration space of a DFES can be divided into two disjoint classes such that every configuration in one class should evolve into one of absorbing states, whereas no configurations in the other class can reach an absorbing state. Since the two classes are separated in terms of toppling dynamics, the system can be made to exhibit an absorbing phase transition (APT) at various points that depend on the initial probability distribution of the configurations. Furthermore, we show that in general the transition point also depends on whether an infinite-size limit is taken before or after the infinite-time limit. To demonstrate, we numerically study the two-dimensional DFES with Bak-Tang-Wiesenfeld toppling rule (BTW-FES). We confirm that there are indeed many thresholds. Nonetheless, the critical phenomena at various transition points are found to be universal. We furthermore discuss a microscopic absorbing phase transition, or a so-called spreading dynamics, of the BTW-FES, to find that the phase transition in this setting is related to the dynamical isotropic percolation process rather than self-organized criticality. In particular, we argue that choosing recurrent configurations of the corresponding ASM as an initial configuration does not allow for a nontrivial APT in the DFES.

    Eckman, Richard; Stackhouse, Paul

    2017-01-01

    The Energy Sector is experiencing increasing impacts from severe weather and shifting climatic trends, as well as facing a changing political climate, adding uncertainty for stakeholders as they make short- and long-term planning investments. Climate changes such as prolonged extreme heat and drought (leading to wildfire spread, for example), sea level rise, and extreme storms are changing the ways that utilities operate. Energy infrastructure located in coastal or flood-prone areas faces inundation risks, such as damage to energy facilities. The use of renewable energy resources is increasing, requiring more information about their intermittency and spatial patterns. In light of these challenges, public and private stakeholders have collaborated to identify potential data sources, tools, and programmatic ideas. For example, utilities across the country are using cutting-edge technology and data to plan for and adapt to these changes. In the Federal Government, NASA has invested in preliminary work to identify needs and opportunities for satellite data in energy sector application, and the Department of Energy has similarly brought together stakeholders to understand the landscape of climate vulnerability and resilience for utilities and others. However, have these efforts improved community-scale resilience and adaptation efforts? Further, some communities are more vulnerable to climate change and infrastructure impacts than others. This session has two goals. First, panelists seek to share existing and ongoing efforts related to energy management. Second, the session seeks to engage with attendees via group knowledge exchange to connect national energy management efforts to local practice for increased community resilience.

  3. Multi-year programming of energy - The energy transition for a green growth

    International Nuclear Information System (INIS)

    2016-01-01

    This document gathers several documents. It contains the decree related to the definition of the multi-year programming of energy (in France), and then a synthesis of this policy which addresses its main objectives: to define a coherent framework for action for energy transition, to improve energy efficiency and reduce the consumption of fossil energies, to accelerate the development of renewable energies, to maintain a high level of security of supply while complying with environmental requirements, to prepare tomorrow's energy system, to develop a clean mobility, and to take economic and social of energy transition into account and to act with territories. The next documents address the implementation framework of the multi-year programming of energy, aspects related to energy demand management, aspects related to energy supply, aspects related to security of supply, to the development of infrastructures and to the flexibility of the electricity system, the strategy for the development of a clean mobility, aspects related to social and economic impacts, aspects related to the French western isles. A report is also proposed as an environmental strategic assessment of this programming and of its part related to the strategy for the development of a clean mobility. The opinion of Environmental Authority on this programming is also provided, as well as an information note published as an answer to this opinion. A debate of the national council for energy transition is included, as well as the opinion of the High Council for Energy, the texts of several amendments notably proposed by EDF, and the opinion of the expert committee for energy transition

    This paper outlines the need to expand and improve public participation in decision-making on energy. In an advanced society like ours you can not continue using the same tools they used a century ago. Provide and transmit by the scientific community to society, information science and technology in an appropriate language that comes to them, giving them opportunities and enabling them to participate objectively in this decision making. There must be a legitimate, honest, sincere and plural debate where the participation of all the actors involved and from all strata of society. (Author)

  5. 'Making the move': relatives' experiences of the transition to a care home.

    Davies, Sue; Nolan, Mike

    2004-11-01

    Despite a growing awareness of the significance of helping a relative to relocate to a care home as a key phase in the caregiving career, relatively few studies in the UK have explored this experience in depth. The research on which the present paper is based sought to better understand experiences of nursing home placement from the viewpoint of relatives. The study was informed by a constructivist perspective. Data were collected in 37 semi-structured interviews involving 48 people who had assisted a close relative to move into a nursing home. Data analysis revealed three phases of the transition from the relatives' perspective: 'making the best of it'; 'making the move'; and 'making it better'. The relatives' experiences across these phases were understood in terms of five continua, reflecting the extent to which they felt they were: operating 'under pressure' or not; 'working together' or 'working alone'; 'supported' or 'unsupported', both practically and emotionally; 'in the know' or 'working in the dark'; and 'in control of events' or not. This paper reports on the findings which relate to the second phase of the transition, 'making the move', which relates to experiences around the time of relocation to the care home environment. The findings suggest that health and social care practitioners have enormous potential to influence relatives' experiences of nursing home entry. Experiences are enhanced if family carers perceive that they are able to work in partnership with care staff in order to ease the transition for the older person.

    2014-01-01

    This paper presents the findings of a study on decision making models for the analysis of capital-risk investors’ preferences on biomass power plants projects. The aim of the work is to improve the support tools for policy makers in the field of renewable energy development. Analytic Network Process (ANP) helps to better understand capital-risk investors preferences towards different kinds of biomass fueled power plants. The results of the research allow public administration to better foresee the investors’ reaction to the incentive system, or to modify the incentive system to better drive investors’ decisions. Changing the incentive system is seen as major risk by investors. Therefore, public administration must design better and longer-term incentive systems, forecasting market reactions. For that, two scenarios have been designed, one showing a typical decision making process and another proposing an improved decision making scenario. A case study conducted in Italy has revealed that ANP allows understanding how capital-risk investors interpret the situation and make decisions when investing on biomass power plants; the differences between the interests of public administrations’s and promoters’, how decision making could be influenced by adding new decision criteria, and which case would be ranked best according to the decision models. - Highlights: • We applied ANP to the investors’ preferences on biomass power plants projects. • The aim is to improve the advising tools for renewable energy policy making. • A case study has been carried out with the help of two experts. • We designed two scenarios: decision making as it is and how could it be improved. • Results prove ANP is a fruitful tool enhancing participation and transparency

    Rezessy, Silvia; Dimitrov, Konstantin; Urge-Vorsatz, Diana; Baruch, Seth

    2006-01-01

    It is widely recognized that many cost-efficient opportunities to employ end-use energy efficiency measures exist in countries in transition (CITs) and that municipal authorities have an essential role to play in capturing these opportunities. The aim of this paper is to review the factors that determine the degree of involvement of local authorities in the market for energy services and energy efficient (EE) equipment in three CITs: Bulgaria, Hungary and the Former Yugoslav Republic of Macedonia (hereafter: Macedonia). We achieve this aim by examining the current status of local governments as the most powerful determinant of municipal market involvement. Two broad groups of factors are discussed: statutory obligations and powers of local governments, especially energy-related tasks, and finance. We explain how specific features within these two areas may influence the motivation of local authorities to improve energy efficiency and their capacity to do so. We argue that greater decentralization is the first step in augmenting the role of local authorities in the market for energy services and EE equipment. Based on the analysis we give recommendations on how to encourage municipal authorities to use market mechanisms more extensively to deliver energy efficiency

  8. The German energy transition: the end of ambitions?

    International Nuclear Information System (INIS)

    Beeker, Etienne

    2017-08-01

    This article proposes an overview of the German situation regarding the implementation of its energy transition policy (Energiewende) which mainly comprised phasing out nuclear and fossil energies, and their replacement by renewable energies. The authors notably comment figures and tables which illustrate the evolution of greenhouse gas emissions in Germany, France and Europe, the evolution of wind and photovoltaic installations in Germany, the status of the energy mix and the shares of renewable energies in primary consumption in Germany and in France, the electricity productions from the different sources in Germany and in France, the structure of electric power tariffs in Germany and in France. Focusing on the German case, they outline that the objectives defined for 2020 for renewable energies are almost reached, but what comes next remains uncertain. They also notice that the objective of phasing out nuclear in 2022 is kept. They discuss the various difficulties faced by the Energiewende: a too slow improvement of energy efficiency, a development of electric vehicles facing realities of the automotive industry, a difficult but necessary phasing out coal. They outline two main challenges: to face some resistance by the population: the risk of black-outs due to the difficult management of renewable intermittency, and a high level of expenses which are mainly paid by small consumers. The future of this policy may also been put into question again after the elections of September 2017

    The effects of renewable energy transitions on energy costs and economic growth have led to cost concerns and a prioritisation of economic issues during the economic crisis. Bulgaria, the EU's poorest state has nevertheless already achieved its 2020 renewable energy targets. This achievement seems to challenge the widely held as- sumption that poorer countries struggle to meet environmental objectives. This paper analyses the drivers and implications of Bulgaria's renewables expansion in orde...

  10. Is there room for hydrogen in energy transition?

    International Nuclear Information System (INIS)

    Beeker, Etienne

    2014-08-01

    As Germany decided to use hydrogen to store huge quantities of renewable energies, this report aims at assessing the opportunities associated with hydrogen in the context of energy transition. The author addresses the various techniques and technologies of hydrogen production, and proposes a prospective economic analysis of these processes: steam reforming, alkaline electrolysis, polymer electrolyte membrane (PEM) electrolysis, and other processes still at R and D level. He gives an overview of existing and potential uses of hydrogen in industry, in energy storage (power-to-gas, power-to-power, methanation) and in mobility (hydrogen-mobility could be a response to hydrocarbon shortage, but the cost is still very high, and issues like hydrogen distribution must be addressed), and also evokes their emergence potential

    regulation in several European countries, the general picture remains that existing regimes in the building sector are withheld and that little innovation in terms of new radical energy efficient solutions is taking place. In order to dissolve such a deadlock in the building sector, there is a need to target...... the capability to coordinate and facilitate this complex transition process. The local scale of policy-formulation has been chosen in this paper in order to describe transition processes from the perspective of practitioners, who are hands on the specific building projects. The local scale provides an in......-depth study of how specific practitioners, such as local planning authorities, building firms, building developers, technical experts and suppliers, interact and coordinate their efforts in the local arena of a specific building project (within a more general framework). The focus on the local scale allows...

  12. Finland: a model of energy transition to be followed?

    2014-09-01

    Published before the debate of the French Parliament on the law on energy transition, i.e. on a new energy model, or on the construction of a low carbon and less energy consuming society to comply with France's international commitments, this report first discusses the French situation, the evolution of its energy policy, the challenge of a search for a balance between a cheap electricity and energy independence, and the plurality of factors and objectives (economic, budgetary, environmental, industrial, societal, political and social) which are sometime contradictory. The second part presents and comments the case of Germany which seems to be a good example regarding energy policy, however it faces some difficulties and pitfalls: a quick evolution of the energy mix in favour of renewable energies, but an always higher cost supported almost only by individuals, a disturbed electricity market, an environmental impact due to the wider use of coal (less expensive than gas). The third part addresses the case of Finland which could be a more inspiring example: no decision to phase out nuclear, no decision of a quick and forced development of renewable energies, modification of the energy mix by the development of local forest resources, an electric system of good quality, a high energetic competitiveness. The report outlines the consistency of the Finnish policy: search for a balance between international commitments of reduction of greenhouse gas emissions, competitive tariffs, and strengthening of energetic independence. The associated choices are discussed, and it appears that the cost-efficiency criterion is prevailing

    Described herein is a method for making a low energy gamma ray collimator which involves corrugating lead foil strips by passing them through pinion wire rollers and gluing corrugated strips between straight strips using an adhesive such as epoxy to build up a honeycomb-like structure. A thin aluminum sheet is glued to both edges of the strips to protect them and to provide a more rigid assembly which may be sawed to a desired shape. (Patent Office Record)

  14. A Framework for Supporting Organizational Transition Processes Towards Sustainable Energy Systems

    Science.gov (United States)

    Buch, Rajesh

    Economic development over the last century has driven a tripling of the world's population, a twenty-fold increase in fossil fuel consumption, and a tripling of traditional biomass consumption. The associated broad income and wealth inequities are retaining over 2 billion people in poverty. Adding to this, fossil fuel combustion is impacting the environment across spatial and temporal scales and the cost of energy is outpacing all other variable costs for most industries. With 60% of world energy delivered in 2008 consumed by the commercial and industrial sector, the fragmented and disparate energy-related decision making within organizations are largely responsible for the inefficient and impacting use of energy resources. The global transition towards sustainable development will require the collective efforts of national, regional, and local governments, institutions, the private sector, and a well-informed public. The leadership role in this transition could be provided by private and public sector organizations, by way of sustainability-oriented organizations, cultures, and infrastructure. The diversity in literature exemplifies the developing nature of sustainability science, with most sustainability assessment approaches and frameworks lacking transformational characteristics, tending to focus on analytical methods. In general, some shortfalls in sustainability assessment processes include lack of: · thorough stakeholder participation in systems and stakeholder mapping, · participatory envisioning of future sustainable states, · normative aggregation of results to provide an overall measure of sustainability, and · influence within strategic decision-making processes. Specific to energy sustainability assessments, while some authors aggregate results to provide overall sustainability scores, assessments have focused solely on energy supply scenarios, while including the deficits discussed above. This paper presents a framework for supporting

    2009-09-01

    This study examined the quality of life of single mothers making the mandatory transition from welfare to work. The Australian government purported that the benefits of making this transition would include higher incomes, better social participation, and improved wellbeing. It is currently unknown, however, how single mothers currently engaged in welfare to work programs evaluate their quality of life. Quality of life scores for 334 single mothers engaged in welfare to work in Australia were compared with normative data. Participants reported significantly lower quality of life scores than the general population for all quality of life domains, highlighting the need to carefully examine welfare to work policies to ensure they promote participants' quality of life.

    International Nuclear Information System (INIS)

    Meyar-Naimi, H.; Vaez-Zadeh, S.

    2012-01-01

    This paper, in the first step, presents an overview of the origination and formulation of sustainable development (SD) concept and the related policy making frameworks. The frameworks include Pressure–State–Response (PSR), Driving Force–State–Response (DSR), Driving Force–Pressure–State–Impact–Response (DPSIR), Driving Force–Pressure–State–Effect–Action (DPSEA) and Driving Force-Pressure-State-Exposure-Effect-Action (DPSEEA). In this regard, 40 case studies using the reviewed frameworks reported during 1994–2011 are surveyed. Then, their application area and application intensity are investigated. It is concluded that PSR, and DPSEA and DPSEEA have the higher and lower application intensities, respectively. Moreover, using Analytical Hierarchy Process (AHP) with a set of criteria, it is shown that PSR and DPSIR have the highest and lowest priorities. Finally, the shortcomings of frameworks applications are discussed. The paper is helpful in selecting appropriate policy making frameworks and presents some hints for future research in the area for developing more comprehensive models especially for sustainable electric energy policy making. - Highlights: ► The origination and formulation of sustainable development (SD) concept is reviewed. ► SD based frameworks (PSR, DSR, DPSIR, DPSEA and DPSEEA) are also reviewed. ► Then, the frameworks application area and intensity in recent years are investigated. ► Finally, the SD concept and the SD based frameworks are criticized. ► It will be helpful for developing more comprehensive energy policy making models.

    2010-01-01

    This research assesses to what extent current Dutch energy transition policy instruments for the existing housing stock can fulfil local executive actors' needs and instigate adoption of energy efficiency measures by them. This is done by studying energy policy instruments for the existing housing stock in the Netherlands and in other European countries, and by an empirical research, which analyses barriers and needs of local executive actors. We found that, despite current Dutch energy transition policy instruments for the existing housing stock seem to fulfil local executive actors' needs to a large extent, complementary policy instruments are needed to stimulate and pressure the incumbent renovation regime. A long-term oriented financial rewarding system is needed to build up a structural market for the deployment of renewables, to increase the number of specialist jobs in the building sector, and to stimulate the development of integrated, standardized, building components. Furthermore, a long-term oriented financial rewarding system for energy efficiency investments in housing renovation projects, and a low VAT rate applied to energy efficient renovation measures, are needed. Finally, enforcement possibilities and sanctions (fines) should become an integrative part of Dutch energy certification regulation to make the certificate become part of a value chain.

    International Nuclear Information System (INIS)

    Aggarwal, K M; Keenan, F P; Msezane, A Z

    2013-01-01

    We report on calculations of energy levels, radiative rates, oscillator strengths and line strengths for transitions among the lowest 253 levels of the (1s 2 2s 2 2p 6 ) 3s 2 3p 5 , 3s3p 6 , 3s 2 3p 4 3d, 3s3p 5 3d, 3s 2 3p 3 3d 2 , 3s 2 3p 4 4s, 3s 2 3p 4 4p and 3s 2 3p 4 4d configurations of Ti VI. The general-purpose relativistic atomic structure package and flexible atomic code are adopted for the calculations. Radiative rates, oscillator strengths and line strengths are reported for all electric dipole (E1), magnetic dipole (M1), electric quadrupole (E2) and magnetic quadrupole (M2) transitions among the 253 levels, although calculations have been performed for a much larger number of levels. Comparisons are made with existing available results and the accuracy of the data is assessed. Additionally, lifetimes for all 253 levels are listed, although comparisons with other theoretical results are limited to only 88 levels. Our energy levels are estimated to be accurate to better than 1% (within 0.03 Ryd), whereas results for other parameters are probably accurate to better than 20%. A reassessment of the energy level data on the National Institute of Standards and Technology website for Ti VI is suggested. (paper)

  19. Supporting the Energy Transition: the Role of Low Interest Rates

    International Nuclear Information System (INIS)

    Monnin, Pierre

    2015-01-01

    Low interest rates tend to favor 'green technologies' competitiveness while also increasing their cost volatility. Our analysis of the impact of interest rates on green energy technologies costs points to three key conclusions: - A low interest rate environment makes green energy technologies more competitive. Hydroelectric power is less expensive than any other technology across the entire spectrum of interest rate levels that we analyzed in this paper. Wind on-shore is competitive with all other technologies up until interest rates of about 8%. - Green energy technologies' LCOEs react more significantly to a change in interest rates than the LCOEs of brown energy technologies, implying a greater volatility for green energy technologies' costs in response to interest rate volatility. A higher volatility is damaging because it brings more uncertainty in investment decisions. As a result, stable interest rates are more beneficial for green energy investments than for brown energy investments. - In order to increase the ratio of green to brown energy investments, we can consider a discount on the interest rates for the former or a premium on interest rates for the latter. Our estimations indicate that, because interest rate changes have a greater impact on the costs of green energy technologies, a discount on green investments' interest rates would be more efficient than a premium on brown investments' interest rates.

    The study of the decay scheme of Mo{sup 99} has been performed on the magnetic iron-less and double focalization spectrograph of the Institute of Nuclear Physics of Lyon. Methods of internal and external conversion have been used. The intensities of the Mo{sup 99} sources used were not strong enough to determine the characteristics of the internal conversion accurately but were sufficient to precise the decay scheme at low energy. We have determined the internal conversion ratio for the transition of 180 KeV, we have got: 0.13 ± 0.03 which is not in agreement with the value given by a previous experiment based on γ-γ coincidence. Our method seems to be more reliable. We confirm the E2 feature of this transition and its 5/2+ spin. We have determined another important parameter for the 180 KeV de-excitation: the percentage of transitions that do not pass by the isomeric level but by the 140 KeV level is (6 ± 2)%, the isomeric level being at 142 KeV. The gamma spectra at low energy has been studied through the photoelectric effect in a lead converter [French] L'etude du schema de desintegration du Mo{sup 99} deja faite par differents auteurs a ete reprise par des methodes de conversion interne et externe, an moyen du spectrographe magnetique sans fer et a double focalisation de l'Institut de Physique Nucleaire de Lyon.

  1. A novel scheme for making cheap electricity with nuclear energy

    International Nuclear Information System (INIS)

    Pettibone, J.S.

    1991-04-01

    Nuclear fuels should produce cheaper electricity than coal, considering their high specific energy and low cost. To exploit these properties, the scheme proposed here replaces the expensive reactor/steam-turbine system with an engine in which the expansion of a gas heated by a nuclear explosion raises a mass of liquid, thereby producing stored hydraulic energy. This energy could be converted to electricity by hydroelectric generation with water as the working fluid or by magnetohydrodynamic (MHD) generation with molten metal. A rough cost analysis suggests the hydroelectric system could reduce the present cost of electricity by two-thirds, and the MHD system by even more. Such cheap power would make feasible large-scale electrolysis to produce hydrogen and other fuels and chemical raw materials. 2 refs., 1 fig

    2015-10-30

    Smart applications of the Internet of Things are improving the performance of buildings, reducing energy demand. Local and smart networks, soft computing methodologies, machine intelligence algorithms and pervasive sensors are some of the basics of energy optimization strategies developed for the benefit of environmental sustainability and user comfort. This work presents a distributed sensor-processor-communication decision-making architecture to improve the acquisition, storage and transfer of thermal energy in buildings. The developed system is implemented in a near Zero-Energy Building (nZEB) prototype equipped with a built-in thermal solar collector, where optical properties are analysed; a low enthalpy geothermal accumulation system, segmented in different temperature zones; and an envelope that includes a dynamic thermal barrier. An intelligent control of this dynamic thermal barrier is applied to reduce the thermal energy demand (heating and cooling) caused by daily and seasonal weather variations. Simulations and experimental results are presented to highlight the nZEB thermal energy reduction.

    2015-01-01

    The Energy Transition (''Energiewende'') is one of the hot topics of the political debate in Germany for some years. As a consequence of ongoing European integration, EU level politics have gained growing importance. The focus of this study is on the interaction of German and EU energy and climate policies. How have German actors influenced EU policy-making processes and in how far are EU policies relevant for national policy-making in Germany? Three case studies look at processes in the fields of electricity market regulation, renewable energy policy and climate protection between 2007 and 2013.

  5. Financing Innovations for the Renewable Energy Transition in Europe

    2016-11-01

    Full Text Available Renewable energy sources are vital to achieving Europe’s 2030 energy transition goals. Technological innovation, driven by public expenditures on research and development, is a major driver for this change. Thus, an extensive dataset on these expenditures of the European Member States and the European Commission, dating back to the early 1970s, was created. This paper creates predictive scenarios of public investment in renewable energy research and development in Europe based on this historical dataset and current trends. Funding from both, European Member States and the European Commission, between today and 2030 are used in the analysis. The impact on the cumulative knowledge stock is also estimated. Two projection scenarios are presented: (1 business as usual; and (2 an advanced scenario, based on the assumption that the Mission Innovation initiative causes public expenditures to increase in the coming years. Both scenarios are compared to the European 2030 climate and energy framework target sets. Results indicate that Member States in Europe currently tend to fund renewables more than the European Commission, but funding from both sources is expected to increase in the future. Furthermore, the European Commission distributes its funding more equally across the various renewable energy sources than Member States.

    have addressed the media at a national or international level. This article investigates the mediating of a local, municipal initiative, i.e. the so-called ‘Energy Town Frederikshavn’ project in northern Denmark, which has set the ambitious goal of complete transition to renewable energy consumption...... and CO2 neutrality within a few years. Using frame analysis, informed by discourse studies, the article analyzes how the project emerged and was established as a public phenomenon in the media coverage, including how it was made intelligible and which social actors were represented as having a say...... on the matter. The findings show several differences to national or international representations of climate change and sustainability, such as a prevalent profiling frame and an indication of a reversal of the so-called Giddens’ paradox....

  7. Local governance from A to Z - Positive glossary of the energy transition

    International Nuclear Information System (INIS)

    Eisermann, Miriam; Donnerer, David; Morel, Diane

    2015-12-01

    This publication invites you to discover the multiple facets of a collaborative city from A-Z, based on our over 25 years' experience of what works well in Europe. The list is, of course, not exhaustive as the beauty of energy transition is the wide and unlimited field of possibilities that it opens up. What it is proposing however is a change of perspective. As the energy landscape is undergoing radical change, from a once hierarchical and monopolistic system to a more distributed and decentralised one, so too should the decision-making architecture. Indeed, a new system cannot be designed using outdated models: in writing a new chapter of our history, we must also empower its new stakeholders. We, the local and regional actors, are these new players, through the role we play in mobilizing civil society and SMEs, tapping into the large array of dispersed renewable or locally recovered energy sources and increasing energy savings and efficiency through ambitious building, urban planning and mobility strategies. This publication complements Energy Cities' '30 proposals for the energy transition of cities' with its many case studies

    2018-04-01

    Full Text Available In the challenge for a sustainable society, carbon-neutrality is a critical objective for all cities in the coming decades. In the EU City-zen project, academic partners collaborate to develop an urban energy transition methodology, which supports cities in making the energy transition to sustainable lifestyles and carbon neutrality. As part of the project, so-called Roadshows are organised in cities that wish to take the first step toward zero-energy living. Each Roadshow is methodologically composed to allow sustainability experts from across Europe to co-create designs, strategies and timelines with local stakeholders in order to reach this vital goal. Following a precursory investigative student workshop (the SWAT Studio, Dubrovnik was the third city to host the Roadshow in November 2016. During these events the characteristics of Dubrovnik, and the district of Gruž in particular, were systematically analysed, leading to useful insights into the current problems and potentials of the city. In close collaboration with local stakeholders, the team proposed a series of interventions, validated by the calculation of carbon emission, to help make Gruž, and in its wake the whole city of Dubrovnik, net zero energy and zero carbon. The vision presented to the inhabitants and its key city decision makers encompassed a path towards an attainable sustainable future. The strategies and solutions proposed for the Dubrovnik district of Gruž were able to reduce the current carbon sequestration compensation of 1200 hectares of forestland to only 67 hectares, an area achievable by urban reforestation projects. This paper presents the City-zen methodology of urban energy transition and that of the City-zen Roadshow, the analysis of the city of Dubrovnik, proposed interventions and the carbon impact, as calculated by means of the carbon accounting method discussed in the paper.

    There are at least two ways for studying large interactions in nucleus-nucleus collisions. One way is to use the method of angular correlations between fission fragments. The aim of the experiments presented here was to make a survey on the role of the various experimental parameters. In that respect three targets have been studied and different projectiles and bombarding energies have been used. Results are presented and discussed

  12. The multi-annual Energy Plan - Executive summary. The energy transition for the green growth

    International Nuclear Information System (INIS)

    2017-07-01

    The multi-annual energy plan aims at completing the transition towards an energy system which is more efficient, less wasteful, more diverse and therefore more resilient. It reaffirms our commitment to reducing energy consumption, particularly energy from fossil fuels. The future of France's energy sector lies in striking a harmonious balance between different energy sources. These strategic decisions will help us to meet our objectives to keep greenhouse gas emissions to a minimum in line with our commitments to the EU and to the Paris Climate Agreement, to protect human health and the environment and to ensure access to energy at a reasonable cost whilst stimulating economic activity and employment in France

  13. Energy transition. To put an end to generally accepted ideas

    International Nuclear Information System (INIS)

    2017-03-01

    In a set of brief texts, this publication shows that many commonly heard statements regarding energy are wrong. These wrong statements are: Germany has replaced its nuclear by coal which is even more polluting and harmful for the climate; Renewable energies will never cover all our electricity needs, and we'll still need nuclear or gas when wind turbines and solar arrays do not produce; French people are largely opposed to renewable energies, notably those located at the proximity of wind energy projects; Doing without nuclear is depriving of an electricity which is lastingly cheaper than that of our neighbours; Closing nuclear and coal plants will automatically increase unemployment, that which is unacceptable in these times of crisis; Renewable energies will have negative impacts on landscapes as territories will be covered with wind turbines and solar arrays; Renewable energies are harmful for the environment (wind turbine kill huge amounts of birds, and solar arrays use rare earth materials); Ecologists always want to create more additional taxes; Car is necessary, notably in rural areas where there is no public transports; Pollution peaks are mainly caused by pollution coming from Germany and by chimneys and farmers, and cars are not responsible for that; Eating organic food is much more expensive; Helping countries of the South to struggle against climate change is an expense France cannot afford; France almost does not emit greenhouse gases in comparison with China and the USA, and thus, why should we make efforts when other countries do not make them?; Thanks to nuclear, France is more energetically independent; Nuclear does not emit greenhouse gases, it's a clean energy

  14. Irrational decision-making in an amoeboid organism: transitivity and context-dependent preferences.

    Latty, Tanya; Beekman, Madeleine

    2011-01-22

    Most models of animal foraging and consumer choice assume that individuals make choices based on the absolute value of items and are therefore 'economically rational'. However, frequent violations of rationality by animals, including humans, suggest that animals use comparative valuation rules. Are comparative valuation strategies a consequence of the way brains process information, or are they an intrinsic feature of biological decision-making? Here, we examine the principles of rationality in an organism with radically different information-processing mechanisms: the brainless, unicellular, slime mould Physarum polycephalum. We offered P. polycephalum amoebas a choice between food options that varied in food quality and light exposure (P. polycephalum is photophobic). The use of an absolute valuation rule will lead to two properties: transitivity and independence of irrelevant alternatives (IIA). Transitivity is satisfied if preferences have a consistent, linear ordering, while IIA states that a decision maker's preference for an item should not change if the choice set is expanded. A violation of either of these principles suggests the use of comparative rather than absolute valuation rules. Physarum polycephalum satisfied transitivity by having linear preference rankings. However, P. polycephalum's preference for a focal alternative increased when a third, inferior quality option was added to the choice set, thus violating IIA and suggesting the use of a comparative valuation process. The discovery of comparative valuation rules in a unicellular organism suggests that comparative valuation rules are ubiquitous, if not universal, among biological decision makers.

  16. Implications of net energy-return-on-investment for a low-carbon energy transition

    Science.gov (United States)

    King, Lewis C.; van den Bergh, Jeroen C. J. M.

    2018-04-01

    Low-carbon energy transitions aim to stay within a carbon budget that limits potential climate change to 2 °C—or well below—through a substantial growth in renewable energy sources alongside improved energy efficiency and carbon capture and storage. Current scenarios tend to overlook their low net energy returns compared to the existing fossil fuel infrastructure. Correcting from gross to net energy, we show that a low-carbon transition would probably lead to a 24-31% decline in net energy per capita by 2050, which implies a strong reversal of the recent rising trends of 0.5% per annum. Unless vast end-use efficiency savings can be achieved in the coming decades, current lifestyles might be impaired. To maintain the present net energy returns, solar and wind renewable power sources should grow two to three times faster than in other proposals. We suggest a new indicator, `energy return on carbon', to assist in maximizing the net energy from the remaining carbon budget.

    2016-01-01

    The French-German office for Renewable energies (OFAEnR) organised a conference on energy storage supporting the energy transition in France and in Germany. In the framework of this French-German exchange of experience, about 140 participants met together to debate about the answer of future storage technologies to the electric power system needs and to the optimum integration of renewable energies at different levels of the power transmission and distribution grid. This document brings together the available presentations (slides) made during this event: 1 - Storage Technologies, Status and Perspectives (Matthias Leuthold); 2 - Which electricity storage needs for 2030, 2050 in France? (David Marchal); 3 - Storage in context of the German 'Energiewende' (Ralf Sitte); 4 - Battery Storage for residential PV Systems: Grid relieving effects (Kai-Philipp Kairies); 5 - Battery Storage for residential PV Systems: Technologies and Market Trends (Kai-Philipp Kairies); 6 - Pumped hydro-stations to ensure a decentralized and flexible storage to integrate the best way RES in the electric system (Pierre Guerrier); 7 - RRKW Feldheim - Primary Frequency Control in a wind feed-in grid (Niklas Netzel); 8 - Smoothing an intermittent generation: interest of generation forecast and storage global management (Etienne Radvanyi); 9 - Power-to-gas after 2030 - A cost-benefit analysis (Thorsten Lenck)

  18. Smart Grids as keys to a successful energy transition

    International Nuclear Information System (INIS)

    Meunier, Stephane

    2013-07-01

    This publication addresses several issues related to the role of smart grids in energy transition. The contributions discuss whether the future of smart grid markets can be found in developing countries, outline that the deployment of smart counters announces the development of smart grids in France, comment the search for a new business model for the smart grid market, and question the role of power storage as a key for the integration of renewable energies into the grid. They also address the case of French non interconnected areas which could be a laboratory to develop and test smart grids. They outline that smart grids display an economic logic against energy poverty, that smart grids in developing countries could be a lever against blackouts and electricity thefts, and that they can be a solution for the electrification of rural areas in developing countries. They present energy cooperatives as a successful model for smart grid projects. A last contribution addresses the smart management of water as a solution to preserve the resource while generating profits

  19. Alternative energy sources or integrated alternative energy systems? Oil as a modern lance of Peleus for the energy transition

    International Nuclear Information System (INIS)

    Szklo, Alexandre; Schaeffer, Roberto

    2006-01-01

    In this viewpoint, we discuss the importance of consorting alternative energy sources with oil, and not of opposing them. That is why we introduce the concept of alternative energy systems, which we feel is broader-ranging and more effective than alternative energy sources, as this deals with the actual transformation process of the global energy system. Alternative energy systems integrate oil with other energy sources and pave the way for new systems, which will benefit from what we call the 'virtues of oil'. They produce energy carriers for multi-fuel and multi-product strategies, where flexibility is a key target, allied to other co-benefits, especially those related to the increased use of renewable energy sources. The concept of alternative energy systems can bring a new light to the oil transition era discussion and might also influence energy policies for promoting renewables

  1. Multi objective decision making in hybrid energy system design

    Science.gov (United States)

    Merino, Gabriel Guillermo

    The design of grid-connected photovoltaic wind generator system supplying a farmstead in Nebraska has been undertaken in this dissertation. The design process took into account competing criteria that motivate the use of different sources of energy for electric generation. The criteria considered were 'Financial', 'Environmental', and 'User/System compatibility'. A distance based multi-objective decision making methodology was developed to rank design alternatives. The method is based upon a precedence order imposed upon the design objectives and a distance metric describing the performance of each alternative. This methodology advances previous work by combining ambiguous information about the alternatives with a decision-maker imposed precedence order in the objectives. Design alternatives, defined by the photovoltaic array and wind generator installed capacities, were analyzed using the multi-objective decision making approach. The performance of the design alternatives was determined by simulating the system using hourly data for an electric load for a farmstead and hourly averages of solar irradiation, temperature and wind speed from eight wind-solar energy monitoring sites in Nebraska. The spatial variability of the solar energy resource within the region was assessed by determining semivariogram models to krige hourly and daily solar radiation data. No significant difference was found in the predicted performance of the system when using kriged solar radiation data, with the models generated vs. using actual data. The spatial variability of the combined wind and solar energy resources was included in the design analysis by using fuzzy numbers and arithmetic. The best alternative was dependent upon the precedence order assumed for the main criteria. Alternatives with no PV array or wind generator dominated when the 'Financial' criteria preceded the others. In contrast, alternatives with a nil component of PV array but a high wind generator component

  2. Toward the renewables - A natural gas/solar energy transition strategy

    Science.gov (United States)

    Hanson, J. A.; Escher, W. J. D.

    1979-01-01

    The inevitability of an energy transition from today's non-renewable fossil base toward a renewable energy base is considered from the viewpoint of the need for a national transition strategy. Then, one such strategy is offered. Its technological building blocks are described in terms of both energy use and energy supply. The strategy itself is then sketched at four points in its implementation; (1) initiation, (2) early transition, (3) late transition, and (4) completion. The transition is assumed to evolve from a heavily natural gas-dependent energy economy. It then proceeds through its transition toward a balanced, hybrid energy system consisting of both centralized and dispersed energy supply technologies supplying hydrogen and electricity from solar energy. Related institutional, environmental and economic factors are examined briefly.

  3. German energy transition at the crossroad: global pressures or green energy island

    International Nuclear Information System (INIS)

    Umbach, Frank

    2015-05-01

    In reaction to the March 2011 nuclear disaster that occurred in Fukushima/Japan, Germany has unilaterally decided to launch an energy transition of hitherto unseen dimensions. Berlin set extremely ambitious objectives such as phasing out nuclear energy by 2020, as well as, in the long run, the creation of a sustainable and autarkic energy system. Reactions to this decision differed. Within her own country, Angela Merkel's energy transition was largely acclaimed, although it represented a total u-turn with respect to the previous policy which consisted of prolonging nuclear reactors' lifespan. Abroad and notably among Germany's European partners, it has, in turn, been heavily criticized. These partners had not been consulted prior to decisions being taken, despite the huge impact these decisions had and continue to have on their own energy security. Four years after Angela Merkel announced the German energy transition, it is obvious that a lot of effort still needs to be put into it and that the objectives defined are far from having been reached. German energy policy has failed to adapt to its global context, notably characterized by the U.S. shale gas revolution, geopolitical upheaval, the great polluters' absent willingness to commit to climate protection, etc. At the time being, it has also failed to find a sustainable equilibrium between environmental protection, energy security and economic competitiveness. Moreover, Germany needs to act in accordance with its European partners, without whom it will not be able to tackle the global challenge of climate change and attain to European energy security. If Germany fails to reach these objectives, it may see its competitiveness and geopolitical influence decline at the global level, which would also have repercussions on the EU's standing in the world.

  4. The transition between energy efficient and energy inefficient states in Cameroon

    International Nuclear Information System (INIS)

    Adom, Philip Kofi

    2016-01-01

    I use a two-state (energy efficient/inefficient) Markov-switching dynamic model to study energy efficiency in Cameroon in a novel manner, employing yearly data covering 1971 to 2012. I find that the duration of an energy inefficient state is about twice as long as an energy efficient state, mainly due to fuel subsidies, low income, high corruption, regulatory inefficiencies, poorly developed infrastructure and undeveloped markets. To escape from an energy inefficient state a broad policy overhaul is needed. Trade liberalization and related growth policies together with the removal of fuel subsidies are useful, but insufficient policy measures; the results suggest that they should be combined with structural policies, aiming at institutional structure and investment in infrastructure. - Highlights: • I investigate the transition between energy efficient/inefficient states. • On the average, energy inefficient state persists more than energy efficient state. • The duration of energy inefficient state is about twice as long as energy efficient state. • Price, income and trade openness have distinct energy saving effect irrespective of state. • A broad policy overhaul is needed to escape the energy inefficient state.

    Maizi, Nadia; Assoumou, Edi; Le Gallic, Thomas

    2017-01-01

    This forward-looking exercise focuses on the energy transition and the compatibility of a society where digital technology has been deployed with France's goal of 'carbon neutrality' by 2072. If we are not careful, climate programs might be compromised owing to the energy needed for information and communications technology. On the supply side, what digital techniques and objects are being designed to address climate problems? On the demand side, what lifestyle trends will this technology trigger in a 'digital society', and what impact will they have on energy consumption? Beyond the results of the scenario imagined herein, it is worthwhile examining a range of decision-making tools for laying out the pathways we would like to take

  7. Economic impact of the energy transition at the local level. Methodologies and case studies

    Maurer, Christiane; Ustinskaya, Elina

    2014-12-01

    An understanding of the mechanisms that link the energy transition to the stimulation of the economy on the ground is indispensable in terms of more efficient targeting of local energy transition policies. Objective evidence of economic results is required, as is a better understanding of economic analysis methods, in order to equip local and regional authorities with the tools required to demonstrate the economic benefits for all the key players. With the 'Economic impact of the energy transition at a local level - Methodologies and case studies' study, Energy Cities illustrates numerous socio-economic aspects of the energy transition and confirms the local economic benefits, through the use of data. As with any complex, new and diffuse process, this field of research is still not fully understood. Appropriate, high-quality analysis at the local level has rarely been carried out to date and a critical assessment of the methods used is necessary. This study will fill a gap and provide suggestions on potential areas for further research in a range of fields which should be further explored and examined in collaboration with local authorities and voluntary partners. Methodology and results The first part of the study sets out the scope of the study and contains a general description of the impact observed and the potential outcome of transition policies in the main green growth sectors: eco-innovation, the energy performance of buildings, renewable energy, sustainable mobility, recycling and industrial ecology. The analysis then focuses on the feedback of six towns and regions with a policy of active sustainable development (building renovation, support for eco-industries, promotion of soft mobility etc.), presented from the point of view of the economic results observed and the evaluation methods used. The study comprises five European authorities - Brussels, Copenhagen, Hannover, Kirklees and the Greater Paris Region, and one North American authority - Nolan County

    This document first presents a project launched on the issue of energy choice for tomorrow for the territory, and more particularly on a shared regional diagnosis and principles for action. A second document reports activities of this research-action project which aimed at making citizen recommendations emerge, and at elaborating an operational territorial tool for energy transition. Then comes the final report of this project. After an introduction which outlines that energy transition is a major stake for the territory, a first chapter discusses which are tomorrow's energies by outlining the climatic emergency, the energy situation at the world level, the perspective of smart cities and communities, national energetic stakes, the role given to citizen, and the perspective of a new relationship to the world and to the nature. The second chapter briefly evokes the perspective for 2050. The next part discusses the societal dimension of energy transition, and examines what could be the engines for change. The next chapter identifies and discusses various debates to be held: on climate situation, on energy resource availability, on human development and on the economic model. The last chapter outlines the role of the territorial scale and of collective dynamics to elaborate and implement scenarios of energy transition

  10. Energy Demand Modeling Methodology of Key State Transitions of Turning Processes

    2017-04-01

    Full Text Available Energy demand modeling of machining processes is the foundation of energy optimization. Energy demand of machining state transition is integral to the energy requirements of the machining process. However, research focus on energy modeling of state transition is scarce. To fill this gap, an energy demand modeling methodology of key state transitions of the turning process is proposed. The establishment of an energy demand model of state transition could improve the accuracy of the energy model of the machining process, which also provides an accurate model and reliable data for energy optimization of the machining process. Finally, case studies were conducted on a CK6153i CNC lathe, the results demonstrating that predictive accuracy with the proposed method is generally above 90% for the state transition cases.

  11. Improving the performance of jaggery making unit using solar energy

    Directory of Open Access Journals (Sweden)

    Lakshmi Pathi Jakkamputi

    2016-09-01

    Full Text Available The thermal performance of open earth pan furnace used conventionally for preparing jaggery (gur is very low. Dry bagasse is used as a fuel to produce heat in a combustion process in the open earth furnace. The energy loss due to inefficient combustion process, the energy loss through exhaust gases and other losses due to furnace wall, convection and radiation bring the thermal efficiency of open earth pan furnace to a low value. Certain quantity of energy produced in combustion process is used to sensibly heat the sugarcane juice to its evaporation temperature. Solar collectors can supply the sensible heat required to raise the sugarcane juice temperature up to its boiling point, thereby reducing the total quantity of heat required in preparing the jaggery. Solar drier can be used to supply hot air required for the combustion process to burn the bagasse in more efficient manner. This paper presents analytical calculations done to study the performance improvement of the jaggery making unit using solar collector and solar drier.

  12. The energy divide: Integrating energy transitions, regional inequalities and poverty trends in the European Union

    Science.gov (United States)

    Bouzarovski, Stefan; Tirado Herrero, Sergio

    2016-01-01

    Energy poverty can be understood as the inability of a household to secure a socially and materially necessitated level of energy services in the home. While the condition is widespread across Europe, its spatial and social distribution is highly uneven. In this paper, the existence of a geographical energy poverty divide in the European Union (EU) provides a starting point for conceptualizing and exploring the relationship between energy transitions – commonly described as wide-ranging processes of socio-technical change – and existing patterns of regional economic inequality. We have undertaken a comprehensive analysis of spatial and temporal trends in the national-scale patterns of energy poverty, as well as gas and electricity prices. The results of our work indicate that the classic economic development distinction between the core and periphery also holds true in the case of energy poverty, as the incidence of this phenomenon is significantly higher in Southern and Eastern European EU Member States. The paper thus aims to provide the building blocks for a novel theoretical integration of questions of path-dependency, uneven development and material deprivation in existing interpretations of energy transitions.

  13. Energy at the Frontier: Low Carbon Energy System Transitions and Innovation in Four Prime Mover Countries

    Science.gov (United States)

    Araujo, Kathleen M.

    All too often, discussion about the imperative to change national energy pathways revolves around long timescales and least cost economics of near-term energy alternatives. While both elements certainly matter, they don't fully reflect what can drive such development trajectories. This study explores national energy transitions by examining ways in which four prime mover countries of low carbon energy technology shifted away from fossil fuels, following the first global oil crisis of 1973. The research analyzes the role of readiness, sectoral contributions and adaptive policy in the scale-up and innovations of advanced, alternative energy technologies. Cases of Brazilian biofuels, Danish wind power, French nuclear power and Icelandic geothermal energy are analyzed for a period of four decades. Fundamentally, the research finds that significant change can occur in under 15 years; that technology complexity need not necessarily impede change; and that countries of different governance approaches and consumption levels can effectuate such transitions. This research also underscores that low carbon energy technologies may be adopted before they are competitive and then become competitive in the process.

  14. Transit of Natural Gas. Monitoring Report on the Implementation of the Transit Provisions of the Energy Charter Treaty

    International Nuclear Information System (INIS)

    2007-03-01

    Natural gas is transported over increasingly large distances from producers to consumers. Most of this transportation takes place by pipelines and often involves crossing multiple national borders. Recent events demonstrated that disputes over energy transit can quickly have multilateral implications for gas supply, demonstrating the need for a framework for reliable cross-border gas flows. The Energy Charter Treaty (ECT) provides a set of binding rules that cover the entire energy chain, including the terms to transport energy across various national jurisdictions. The transit provisions of the Treaty support the reliability of established flows and the creation of new transport capacity, thus contributing to the reliability of gas transit. The Energy Charter's Group on Trade and Transit monitors and assists in the implementation of the ECT and its instruments on trade and transit and suggests improvements of implementation. The present report monitors the implementation of the Energy Charter transit principles for natural gas by giving an analysis of its legislative and practical aspects in selected member countries of the ECT constituency

    The report outlines that the cost of nuclear energy in France is largely under-assessed because of the under-evaluation of the future dismantling of nuclear installations and of the management of radioactive wastes. It outlines that provisions made for this dismantling are insufficient, opaque and very risky. This report proposes the creation of a fund independent from nuclear operators to make pay the actual cost of nuclear energy and reduce the French electrical dependence on this energy, to secure long-term financing to finance the dismantling, to bring the financing for the decades to come to finance energy transition, to finance energy transition at reasonable rates, and to clarify the governance for phasing out nuclear

    The ground is littered with projects that failed because of strong public opposition, including natural gas and coal power plants proposed in Idaho over the past several years. This joint project , of the Idaho National Laboratory, Boise State University, Idaho State University and University of Idaho has aimed to add to the tool box to reduce project risk through encouraging the public to engage in more critical thought and be more actively involved in public or social issues. Early in a project, project managers and decision-makers can talk with no one, pro and con stakeholder groups, or members of the public. Experience has shown that talking with no one outside of the project incurs high risk because opposition stakeholders have many means to stop most (if not all) energy projects. Talking with organized stakeholder groups provides some risk reduction from mutual learning, but organized groups tend not to change positions except under conditions of a negotiated settlement. Achieving a negotiated settlement may be impossible. Furthermore, opposition often arises outside pre-existing groups. Standard public polling provides some information but does not reveal underlying motivations, intensity of attitudes, etc. Improved methods are needed that probe deeper into stakeholder (organized groups and members of the public) values and beliefs/heuristics to increase the potential for change of opinions and/or out-of-box solutions. The term “heuristics” refers to the mental short-cuts, underlying beliefs, and paradigms that everyone uses to filter and interpret information, to interpret what is around us, and to guide our actions and decisions. This document is the final report of a 3-year effort to test different public discourse methods in the subject area of energy policy decision-making. We analyzed 504 mail-in surveys and 80 participants in groups on the Boise State University campus for their preference, financial support, and evaluations of eight attributes

    Full Text Available The Bologna Declaration has opened a stage of big and deep changes in the internal university organization, external cooperation, teaching models and methods, among other., all over the European countries. Here we will present and discuss a pilot experience conducted at the Engineering Department of the University of Trás-os-Montes e Alto Douro, Portugal, during the second year of that transition period. In brief, we will present a set of non-mandatory courses proposed to the students of each individual syllabus, with one hundred hours duration, each, approximately seven hours/week, fifteen weeks long, with the permanent help of a specialized trainer to aid the students in their "homework". The formal bureaucratic transition is also presented. Design and implementation issues, supported on problem-based learning and experimental lab learning classes, final assessment results, as well as the opinion of the students, are presented and analyzed. We believe that this methodology helped to make the transition smoother to the students, but also to the teaching staff.

    Research in structural monitoring has focused primarily on drawing inference about the health of a structure from the structure’s response to ambient or applied excitation. Knowledge of the current state can then be used to predict structural integrity at a future time and, in principle, allows one to take action to improve safety, minimize ownership costs, and/or increase the operating envelope. While much time and effort has been devoted toward data collection and system identification, research to-date has largely avoided the question of how to choose an optimal maintenance plan. This work describes a structured decision making (SDM) process for taking available information (loading data, model output, etc.) and producing a plan of action for maintaining the structure. SDM allows the practitioner to specify his/her objectives and then solves for the decision that is optimal in the sense that it maximizes those objectives. To demonstrate, we consider the problem of a Naval vessel transiting a fixed distance in varying sea-state conditions. The physics of this problem are such that minimizing transit time increases the probability of fatigue failure in the structural supports. It is shown how SDM produces the optimal trip plan in the sense that it minimizes both transit time and probability of failure in the manner of our choosing (i.e., through a user-defined cost function). The example illustrates the benefit of SDM over heuristic approaches to maintaining the vessel.

    The electrochemical oxidation of pulp and paper making wastewater assisted by transition metal (Co, Cu) modified kaolin in a 200 ml electrolytic batch reactor with graphite plate as electrodes was investigated. H 2 O 2 , which produced on the surface of porous graphite cathode, would react with the catalysts to form strong oxidant (hydroxyl radicals) that can in turn destruct the pollutants adsorbed on the surface of kaolin. The transition metal (Co, Cu) modified kaolin was also characterized by XRD and SEM before and after the modification and the results showed that the transition metals were completely supported on kaolin and formed a porous structure with big BET surface. The mechanism was proposed on the basis of XPS analysis of the catalyst after the degradation process. Series of experiments were also done to prove the synergetic effect of the combined oxidation system and to find out the optimal operating parameters such as initial pH, current density and amount of catalyst. From the results it can be founded that when the initial pH was at 3, current density was 30 mA cm -2 ; catalyst dose was 30 g dm -3 , COD (chemical oxygen demand) removal could reach up to 96.8% in 73 min

    The ab initio calculation of quasiparticle (QP) energies is a technically and computationally challenging problem. In condensed matter physics, the most widely used approach to determine QP energies is the G W approximation. Although the G W method has been widely applied to many typical semiconductors and insulators, its application to more complex compounds such as transition metal oxide perovskites has been comparatively rare, and its proper use is not well established from a technical point of view. In this work, we have applied the single-shot G0W0 method to a representative set of transition metal oxide perovskites including 3 d (SrTiO3, LaScO3, SrMnO3, LaTiO3, LaVO3, LaCrO3, LaMnO3, and LaFeO3), 4 d (SrZrO3, SrTcO3, and Ca2RuO4 ), and 5 d (SrHfO3, KTaO3, and NaOsO3) compounds with different electronic configurations, magnetic orderings, structural characteristics, and band gaps ranging from 0.1 to 6.1 eV. We discuss the proper procedure to obtain well-converged QP energies and accurate band gaps within single-shot G0W0 by comparing the conventional approach based on an incremental variation of a specific set of parameters (number of bands, energy cutoff for the plane-wave expansion and number of k points) and the basis-set extrapolation scheme [J. Klimeš et al., Phys. Rev. B 90, 075125 (2014), 10.1103/PhysRevB.90.075125]. Although the conventional scheme is not supported by a formal proof of convergence, for most cases it delivers QP energies in reasonably good agreement with those obtained by the basis-set correction procedure and it is by construction more useful for calculating band structures. In addition, we have inspected the difference between the adoption of norm-conserving and ultrasoft potentials in G W calculations and found that the norm violation for the d shell can lead to less accurate results in particular for charge-transfer systems and late transition metals. A minimal statistical analysis indicates that the correlation of the G W data

    Science, Technology, and Math (STEM) fields are responsible for more than half of our sustained economic expansion, and over the past 25 years the science and engineering workforce has remained at over 5% of all U.S. jobs. However, America lags behind other nations when it comes to STEM education; globally, American students rank 23th in math and 31st in science. While our youngest students show an interest in STEM subjects, roughly 40% of college students planning to major in STEM switch to other subjects. Women and minorities, 50% and 43% of school-age children, are disproportionally underrepresented in STEM fields (25% and 15%, respectively). Studies show that improved teacher curriculum combined with annual student-centered learning summer programs can promote and sustain student interest in STEM fields. Many STEM fields appear superficially simple, and yet can be truly complex and controversial topics. Carnegie Mellon University's Center for Climate and Energy Decision Making focuses on two such STEM fields: climate and energy. In 2011, we created SUCCEED: the Summer Center for Climate, Energy, and Environmental Decision Making. SUCCEED consisted of two pilot programs: a 2-day workshop for K-12 teacher professional development and a free 5-day summer school targeted at an age gap in the university's outreach, students entering 10th grade. In addition to teaching lessons climate, energy, and environment, the program aimed to highlight different STEM careers so students could better understand the breadth of choices available. SUCCEED, repeated in 2012, was wildly successful. A pre/post test demonstrated a significant increase in understanding of STEM topics. Furthermore, SUCCEED raised excitement for STEM; teachers were enthusiastic about accurate student-centered learning plans and students wanted to know more. To grow these efforts, an additional component has been added to the SUCCEED 2013 effort: online publicly available curricula. Using the curricula form

    The universal adoption of fiat currencies and of the fractional reserve banking system coincided with access to and ability to utilize energy-dense fossil fuels leading to unprecedented rates of economic expansion. The depletion of economically recoverable fossil fuels though sets the stage for systemic crises as it is not adequately priced in the current market system. An energy-based system of exchange can be adopted in parallel to or in place of fiat currencies in order to facilitate a sustainable energy transition (SET) and mitigate the impacts of such crises. Energy-backed and energy-referenced currencies are discussed as two possible variants for their ability to realign the economic system to the thermodynamic limits of the physical world. The primary advantage of an energy-referenced currency over the current mechanisms for SET (like feed-in-tariffs or carbon taxes) is realized with the decoupling of the monetary and credit functions, especially when debt is tied to future energy availability. While energy-backed (credit) systems can be easier to adopt on a regional scale, the full transition to an energy-reference currency system requires significant reform of the financial and monetary system although it would not radically disrupt the current economic valuations given the high degree of correlation between value and embodied energy.

  5. Three essays on decision-making in energy policy

    Science.gov (United States)

    Wendling, Zachary Ann

    This dissertation examines three issues surrounding decision-making in energy policy. Over the past decade, technological advances in horizontal drilling and hydraulic fracturing have allowed the economical extraction of natural gas and petroleum from shale basins. Thus far, natural gas has been produced from shale at a commercial scale only in certain American States and Canadian Provinces, though potential shale plays exist elsewhere in North America and the world. Whether, how, and to what extent SGD diffuses to new shale basins and jurisdictions will depend on several questions about energy policy. The first chapter examines the potential for SGD in the European Union. Among EU institutions, the European Parliament has been the strongest proponent for regulation of SGD, preferring a balance between environmental protection and opportunities for economic development, energy security, and climate mitigation. Analysis of roll call voting on SGD in the Seventh European Parliament shows that ideological preferences are the primary explanation of voting behavior, followed by national interests in decarbonization. Prospects for further regulatory action are discussed. ? The second chapter takes a closer look at the potential of shale gas to facilitate decarbonization in the electricity sector. Proponents of SGD have claimed that high carbon fossil fuels can be immediately phased out and replaced in the short term by power plants that burn cheap, abundant natural gas, which emits half the greenhouse gasses over a well-to-wire life cycle. A value of information analysis examines the conditions under which this may be so and quantifies how valuable it would be to have perfect information about uncertain parameters in a cost function characterizing the global electricity sector. The third chapter is describes a new tool of policy analysis, the Indiana Scalable Energy-Economy Model (IN-SEEM). State and local governments have played an increasing role in energy and climate

    The energy transition from fossil fuels to renewables is already ongoing, but it will be a long and difficult process because the energy system is a gigantic and complex machine. Key renewable energy production data show the remarkable growth of solar electricity technologies and indicate that crystalline silicon photovoltaics (PV) and wind turbines are the workhorses of the first wave of renewable energy deployment on the TW scale around the globe. The other PV alternatives (e.g., copper/indium/gallium/selenide (CIGS) or CdTe), along with other less mature options, are critically analyzed. As far as fuels are concerned, the situation is significantly more complex because making chemicals with sunshine is far more complicated than generating electric current. The prime solar artificial fuel is molecular hydrogen, which is characterized by an excellent combination of chemical and physical properties. The routes to make it from solar energy (photoelectrochemical cells (PEC), dye-sensitized photoelectrochemical cells (DSPEC), PV electrolyzers) and then synthetic liquid fuels are presented, with discussion on economic aspects. The interconversion between electricity and hydrogen, two energy carriers directly produced by sunlight, will be a key tool to distribute renewable energies with the highest flexibility. The discussion takes into account two concepts that are often overlooked: the energy return on investment (EROI) and the limited availability of natural resources-particularly minerals-which are needed to manufacture energy converters and storage devices on a multi-TW scale. © 2016 WILEY-VCH Verlag GmbH & Co.

    The biological cycles of milk production and reproduction determine dairying profitability thus making management decisions dynamic and time-dependent. Diseases also negatively impact on net earnings of a dairy enterprise. Transition cows in particular face the challenge of negative energy balance (NEB) and/or disproportional energy metabolism (fatty liver, ketosis, subacute, acute ruminal acidosis); disturbed mineral utilization (milk fever, sub-clinical hypocalcemia); and perturbed immune function (retained placenta, metritis, mastitis). Consequently NEB and reduced dry matter intake are aggravated. The combined effects of all these challenges are reduced fertility and milk production resulting in diminishing profits. Risk factors such as NEB, inflammation and impairment of the immune response are highly cause-and-effect related. Thus, managing cows during the transition period should be geared toward reducing NEB or feeding specially formulated diets to improve immunity. Given that all cows experience a reduced feed intake and body condition, infection and inflammation of the uterus after calving, there is a need for further research on the immunology of transition dairy cows. Integrative approaches at the molecular, cellular and animal level may unravel the complex interactions between disturbed metabolism and immune function that predispose cows to periparturient diseases.

    The transformation process of the German energy industry is advancing. The power line and storage infrastructure still appears to be very neglected. The 2050 climate protection plan, but also the EU winter package, is an all-electric approach despite sector-specific targets. In addition to the exorbitant expansion requirements for renewables, infrastructures with enormous transport and storage potential are ''given away''. As in the interview with OGE CEO Stephan Kamphues becomes clear, an efficient energy transition requires an intelligent coupling of different sectors and infrastructures, ultimately even perhaps network convergence. [German] Der Transformationsprozess der deutschen Energiewirtschaft schreitet voran. Immer noch stark vernachlaessigt erscheint die Leitungs- und Speicherinfrastruktur. Dem Klimaschutzplan 2050, aber auch dem EU-Winterpaket wohnt trotz sektorspezifischer Ziele ein all electric-Ansatz inne. Neben exorbitantem Ausbaubedarf an Erneuerbaren ''verschenkt'' man damit Infrastrukturen mit riesigem Transport- und Speicherpotenzial. Wie im Interview mit OGE-Geschaeftsfuehrer Stephan Kamphues deutlich wird, erfordert eine effiziente Energiewende eine intelligente Kopplung verschiedener Sektoren und Infrastrukturen, letztendlich vielleicht sogar Netzkonvergenz.

    As the depletion of energy resources, their unequal use by a rich world on the one hand and developing countries on the other hand will be the key issues for a necessary energy transition, and as these issues come along the problem of climate change, the author more particularly discusses the French situation and perspectives. He discusses and compares the benefits, risks and drawbacks of nuclear energy (a rather clean energy in terms of greenhouse gas emission) with that of other energy sources. He also discusses and compares the possible scenarios of energy transition for France on a medium and on a long term. After some generalities on the military and civil use of nuclear energy (risks associated with nuclear energy, cost of nuclear energy), he proposes an overview of geopolitical aspects related to energy (relationship between demography and energy, actual and estimated energy sources). He describes the main elements of nuclear physics (atom structure, neutron reactions, thermonuclear fusion, radioactivity, exposure sources and regulation), and presents the various nuclear technologies (historical evolution, operation principles of nuclear power plants, nuclear technologies, PWR design and return on experience, EPR, the experimental ITER reactor). He recalls and comments the main nuclear accidents and their consequences (Three Mile Island, Chernobyl, Fukushima), addresses the issue of nuclear wastes (origin, processing and storage, packaging and management for the different types of wastes). Then, he addresses the climate issue and more particularly the greenhouse effect and its impact on climate. The next chapter proposes an overview of the world electricity production and consumption and of the production of renewable energies. The author compares the costs of the different technologies of electricity production, and then discusses the perspectives in terms of energy price, energy and electricity demand by different sectors

    Cooperation on energy matters has been a matter of priority in Franco-German consultations for some time. Not only is close coordination advisable due to the geographic proximity of Europe's two largest national energy markets. Their growing degree of economic (and energy) integration makes it necessary. The significance of energy policy for industrial policy on both sides of the Rhine is unmistakable. While policy approaches in the two countries' energy sectors have differed in the past and in some ways continue to do so, this has not diminished the topic's relevance or lessened the importance of cross-border cooperation. What is new is that both states are now pursuing the same goal: energy transformation (known as Energiewende, or 'transition energetique', depending on which side of the Rhine you are on). There are therefore plenty of good reasons to strive for closer cooperation on matters of energy policy and, in doing so, help bridge some of the gaps in the sputtering Franco-German relationship.

  15. The role of conventional and unconventional gas in the energy transition in Asia

    International Nuclear Information System (INIS)

    2017-01-01

    Energy and environmental issues are one of the main challenges for humanity in the 21. Century. Global growth in energy demand links to environmental concerns including pollution, global warming and reduction of CO 2 emissions. In particular, it is an urgent request in rapidly growing developing regions such as Asian countries. Using cleaner energy sources, renewable energy instead of traditional energy sources like coal and oil is an inevitable option in the future. In the current context, natural gas is seen as a clean energy source which plays a major role in the energy transition process towards a low-carbon economy. The consequences for natural gas markets are significant and the condition of this change is an abundant supply of natural gas. The development of unconventional gas, particularly shale gas, provides an opportunity to expand the global gas supply. This is illustrated by the 'shale gas revolution' in US which has profoundly changed the regional gas markets. However, this 'revolution' is hardly reproducible in other regions of the world. This thesis demonstrates particularly that apart from geological, institutional conditions (taxation, property rights), economic (prices, technologies) and organizational (free markets) are necessary for a large scale development of unconventional resources. This research also shows that most of these conditions are not met in Europe or Asia (especially in China). Therefore, an energy transition by natural gas to meet climate challenges in Asia will be solved through imports, rather than through regional production. From three scenarios of the POLES model based on assumptions about climate policy, shale gas development and rapid increase of demand for gas in the energy mix (particularly in Asia), two main conclusions emerge. The developments of shale gas with low cost in the USA make the global gas supply abundant and more competitive than other energies, particularly coal. Therefore, even without

    2015-01-01

    This publication states the opinion of the SFEN (the French Society of Nuclear Energy) about the project proposed by the French Ministry of Ecology for the creation of a label named 'Energy transition and climate' for the financial sector. Such a label aims at mobilising a part of savings for the benefit of energy and ecology transition, and at bringing the French ecological expertise at the European level. In this document, the SFEN expresses its surprise that labels will not be awarded to activities related to the nuclear sector whereas, as it is herein commented and outlined, nuclear energy is a low-carbon energy, and meets environmental and social requirements associated with the label (preservation of air quality, optimisation of the water resource by nuclear plants, strict regulation and controls of releases made by nuclear installations, management of the uranium resource, measures of protection of biodiversity about nuclear sites, exemplary governance and dialogue on environmental and social issues with the public)

  20. Synthesis of the national debate on France's energy transition presented by the debate national Council

    International Nuclear Information System (INIS)

    2013-07-01

    This synthesis of the French national debate on energy transition highlights and discusses fifteen challenges which deal with the respect of France's commitments, the struggle against energy poverty, the role of energy efficiency and of energy saving in a new economic growth model with stakes of improved competitiveness and job creation, an energy mix which results in low carbon emissions, and in a secure, diversified, balanced and competitive energy supply. These challenges also concern levers of success for transition (investment, development of local abilities, a more ambitious and better coordinated European policy), and transition governance

    1996-01-01

    Every two years a national conference on energy is held in Romania under the auspices of Romanian Electricity Authority (RENEL). The CNC'96 Conference entitled 'Improving Energy Efficiency in a Transition Economy' has taken place in the Black Sea resort Neptun-Olimp, on September 1-5, 1996. The conference was divided in 8 sections covering the subjects: 1) Energy policies and strategies - Financing of refurbishment and development; 2) Clean and efficient technologies of the fossil fuels - Renewable energy sources; 3) Rehabilitation - Retrofitting of power facilities; 4) Nuclear Power; 5) Predictive and preventive maintenance technologies; 6) Management and process information systems; 7) Environment conservation and mitigating measures; and 8) Energy end-use. An opening talk was given by V.Romert, the Director General of RENEL, and keynote addresses were presented by I.Lindsay, WEC Secretary General (Energy in an era of change and the WEC within it), by J.E.Gray, Vice Chairman of the Atlantic Council of the United States (Global Energy Outlook), and by F.Meslier, Director of the EDF East Energy Unit, Ile de France and Chairman of the 37 Study Committee of CIGRE (Quelques evolutions recentes de la CIGRE et de son Comite 37).

  2. Assessing Smart Grids contribution to the energy transition with long-term scenarios

    International Nuclear Information System (INIS)

    Bouckaert, Stephanie

    2013-01-01

    In the context of discussions on the energy transition, the general consensus is that part of the solution could come from Smart Grids to deal both with climate and energy issues. Prospective energy systems models may be used to estimate the long-term development of the energy system in order to meet future energy demands while taking into account environmental and technical constraints. These historical models are demand driven and should from now on evolve to considerate future developments of the electricity system. In this study, we have implemented some functionalities related to the concept of Smart Grids in a long-term planning model (demand-side integration, storage, renewable energy). This approach makes it possible to evaluate their benefits separately or collectively, taking into account possible interactions between these functionalities. We have also implemented an indicator reflecting the level of reliability of the electricity system in our model. This additional parameter enables to constrain future electricity systems to ensure a level of reliability identical to the existing one. Our analysis is demonstrated by the case of the Reunion Island, which aims to produce electricity using 100% renewable sources by 2030, and for which Smart Grids functionalities are also potential solutions for reaching this objective.

  3. Distributional Challenges of Sustainability Policies—The Case of the German Energy Transition

    Directory of Open Access Journals (Sweden)

    Erik Gawel

    2015-12-01

    Full Text Available Sustainability policies based on the economic rationale of providing incentives to get prices right inevitably place a significant burden on society and often raise distributional concerns. The social acceptability of Germany’s energy transition towards more sustainable generation and usage of energy is frequently the subject of such critical appraisals. The discourse centres upon the burden imposed on electricity users as a result of the promotion of renewable energy sources in the electricity sector in accordance with the German Renewable Energy Sources Act (EEG. A regressive EEG surcharge is suspected of driving up energy prices unreasonably and of being socially unjust. It is also argued that high-income utility owners profit from the EEG system at the expense of low-income electricity consumers (redistribution from bottom to top. The aim of this paper is to examine the validity of these two hypotheses and to show that both exhibit substantial theoretical and empirical weaknesses, with climate and environmental policy being played off against social policy in a questionable manner. At the same time, the article points out remaining conflicts between energy policy and social policy and makes corresponding policy recommendations for their resolution, thus contributing to reconciling distributional concerns arising in the context of incentive-oriented sustainability governance.

  4. Europe's energy transition. The big five recommendations to guide and inspire EU policy-makers

    International Nuclear Information System (INIS)

    2014-09-01

    The energy transition is more than a shift from one energy system (finite resources) to another (more renewable and low energy-based). Our century's challenge is to radically reduce our energy use. The local level is where the new energy paradigm is happening. Ambitious policies at European level are crucial to speed up the movement

  5. Dimensions of Rational Decision-Making during the Demographic Transition; Aranjuez (Spain Revisited

    Directory of Open Access Journals (Sweden)

    David Reher

    2015-03-01

    Full Text Available A set of linked reproductive histories taken from the Spanish town of Aranjuez during the demographic transition is used to address key issues regarding reproductive change and reproductive choice. This paper builds on the existing literature and especially on the findings first shown in Reher & Sanz-Gimeno (2007 and in Van Poppel et al. (2012 where the links between childhood survival and reproductive decision-making were specified. This paper goes beyond the original ones in two important ways: (a the sex composition of the surviving sibset is included in the analysis and (b behavior is modeled by means of event history analysis. In these models, controls for the survival status of the previous child are introduced so as to distinguish between biological factors related to the cessation of breastfeeding and both short term (child replacement and more long-term reproductive strategies. The results offer convincing proof that couples were continually regulating their fertility in order to achieve reproductive goals both in terms of net fertility and of the sex composition of the resulting sibset. Here results show that both sexes were desired by parents but that lack of surviving males had greater influence on fertility behavior. As expected, controls for the survival status of the previous-born child were important though they did not diminish appreciably the overall effect of the number of surviving offspring. This article offers strong proof for the existence of active decision-making during the demographic transition and applies a method to model these behaviors over the full reproductive history of the couple.

  6. A qualitative study of systemic influences on paramedic decision making: care transitions and patient safety.

    Paramedics routinely make critical decisions about the most appropriate care to deliver in a complex system characterized by significant variation in patient case-mix, care pathways and linked service providers. There has been little research carried out in the ambulance service to identify areas of risk associated with decisions about patient care. The aim of this study was to explore systemic influences on decision making by paramedics relating to care transitions to identify potential risk factors. An exploratory multi-method qualitative study was conducted in three English National Health Service (NHS) Ambulance Service Trusts, focusing on decision making by paramedic and specialist paramedic staff. Researchers observed 57 staff across 34 shifts. Ten staff completed digital diaries and three focus groups were conducted with 21 staff. Nine types of decision were identified, ranging from emergency department conveyance and specialist emergency pathways to non-conveyance. Seven overarching systemic influences and risk factors potentially influencing decision making were identified: demand; performance priorities; access to care options; risk tolerance; training and development; communication and feedback and resources. Use of multiple methods provided a consistent picture of key systemic influences and potential risk factors. The study highlighted the increased complexity of paramedic decisions and multi-level system influences that may exacerbate risk. The findings have implications at the level of individual NHS Ambulance Service Trusts (e.g. ensuring an appropriately skilled workforce to manage diverse patient needs and reduce emergency department conveyance) and at the wider prehospital emergency care system level (e.g. ensuring access to appropriate patient care options as alternatives to the emergency department). © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

    Althoff, Jens; Hutinet, Laurent; Belliard, David; Boulanger, Vincent; Ruedinger, Andreas

    2017-01-01

    This publication first discusses and denies five popular beliefs often heard or read in France about the German energy transition: Germany pollutes us with its coal-fired plants, phasing out nuclear is impossible, 100 per cent of renewable energies is an utopia, energy transition slows down the economy, we will never be able to move without oil. The other articles present the example of a German small town where inhabitants took charge of electric power production, outline that the German energy transition comes along an actual democratic revolution through the appropriation of renewable energy production tools, and discuss the difficult issue of phasing out carbon

  8. Energy transition: a new opportunity for the French-German cooperation

    International Nuclear Information System (INIS)

    Ruedinger, Andreas

    2015-01-01

    As France and Germany are both defining new energy policies, but in different ways (Germany has focused on a reform of the law on renewable energies, and France aims at a reduction of the nuclear share from 75 to 50 per cent by 2025), the author examines whether the French strategy is realistic and how it can be explained from a political point of view, how energy transition can be successfully implemented, and to what extent it may influence the German policy within the framework of present discussions on the EU energy-climate package and of bilateral cooperation. The author first outlines the powerful role of nuclear energy in the history of French energy policy, proposes a brief overview of the evolution of debates in France on energy policy from the beginning of the 2000's, indicates and discusses the main objectives of the present bill project on energy transition, and proposes a comparison of French and German objectives regarding energy transition by 2020, 2030 and 2050. He evokes some practical aspects (discussion about Fessenheim plant shutting down, issues of energy prices). He comments the planned implementation of a new economic model based on a green growth, discusses the issue of energy transition in the electricity sector and in the transport sector, and the relationship between energy transition and decentralisation. Perspectives are briefly discussed regarding the credibility of the French policy and the commitment of both countries in energy transition

  9. Energy equity: will the UN Sustainable Energy For All initiative make a difference

    2012-05-15

    Access to affordable modern energy services may not be a Millennium Development Goal (MDG) but without it, sustainable development, indeed the MDGs themselves, cannot be achieved. Yet energy access remains an area of great global inequity. On one hand, wealthy countries and communities consume vast amounts of often subsidised energy resources every day. On the other hand, 1-in-5 people lives with no access to grid electricity, and around 40 per cent of the world's population (nearly three billion people) lack the technologies to make cooking fuels clean, safe and efficient. Can the UN's Sustainable Energy for All initiative in 2012 redress the balance? Perhaps, but only if it puts improving the lives of the poorest and most vulnerable at the heart of its efforts.

    A highly topical issue, energy transition has become the only possible response to the challenges posed by climate change, the depletion of easily accessible natural resources and the changes in the demand for energy. The ESEC considers that energy transition must be a response to the climatic, ecological, economic and social challenges which we face. It will require proactive engagement in order to achieve a low-carbon, energy-efficient society, which only a strong political will can create

    The most fundamental assumption of the standard cosmological model (ΛCDM) is that the universe is homogeneous on large scales. This is clearly not true on small scales, where clusters and voids exist, and some studies seem to suggest that galaxies follow a fractal distribution up to very large scales 200 h-1 Mpc or more), whereas the ΛCDM model predicts transition to homogeneity at scales of ~100 h-1 Mpc. Any cosmological measurements made below the scale of homogeneity (such as the power spectrum) could be misleading, so it is crucial to measure the scale of homogeneity in the Universe. We have used the WiggleZ Dark Energy Survey to make the largest volume measurement to date of the transition to homogeneity in the galaxy distribution. WiggleZ is a UV-selected spectroscopic survey of ~200,000 luminous blue galaxies up to z=1, made with the Anglo-Australian Telescope. We have corrected for survey incompleteness using random catalogues that account for the various survey selection criteria, and tested the robustness of our results using a suite of fractal mock catalogues. The large volume and depth of WiggleZ allows us to probe the transition of the galaxy distribution to homogeneity on large scales and over several epochs, and see if this is consistent with a ΛCDM prediction.

    2016-11-15

    One of the most widely accepted benefits of enhanced physical activity is an improvement in the symptoms of depression, including the facilitation of decision making. Up until now, these effects have been shown in rodents and humans only. Little is known about their evolutionary origin or biological basis, and the underlying cellular mechanisms also remain relatively elusive. Here, we demonstrate for the first time that preceding motor activity accelerates decision making in an invertebrate, the pond snail Lymnaea stagnalis To investigate decision making in a novel environment, snails, which normally live in water, were placed on a flat dry surface to simulate the potentially threatening consequence of being in an arid environment. This stimulus initiated two distinct phases in snail behaviour: slow circular movements, followed by intense locomotion in a chosen direction. The first phase was prolonged when the test arena was symmetrically lit, compared with one with an apparent gradient of light. However, forced muscular locomotion for 2 h prior to the test promoted the transition from random circular motions to a directional crawl, accompanied by an increase in crawling speed but with no effect on the choice of direction. Intense locomotion for 2 h also produced a strong excitatory effect on the activity of serotonergic neurons in L. stagnalis Our results suggest that the beneficial effects of physical exercise on cognitive performance in mammals might have deep roots in evolution, granting the opportunity to unravel the origins of such effects at the single-neuron and network levels. © 2016.

    Rane, M. V.; Uphade, D. B.

    2017-08-01

    Novel Long Stroke Reciprocating Compressor is analysed for jaggery making while avoiding burning of bagasse for concentrating juice. Heat of evaporated water vapour along with small compressor work is recycled to enable boiling of juice. Condensate formed during heating of juice is pure water, as oil-less compressor is used. Superheat of compressor is suppressed by flow of superheated vapours through condensate. It limits heating surface temperature and avoids caramelization of sugar. Thereby improves quality of jaggery and eliminates need to use chemicals for colour improvement. Stroke to bore ratio is 0.6 to 1.2 in conventional reciprocating drives. Long stroke in reciprocating compressors enhances heat dissipation to surrounding by providing large surface area and increases isentropic efficiency by reducing compressor outlet temperature. Longer stroke increases inlet and exit valve operation timings, which reduces inertial effects substantially. Thereby allowing use of sturdier valves. This enables handling liquid along with vapour in compressors. Thereby supressing the superheat and reducing compressor power input. Longer stroke increases stroke to clearance ratios which increases volumetric efficiency and ability of compressor to compress through higher pressure ratios efficiently. Stress-strain simulation is performed in SolidWorks for gear drive. Long Stroke Reciprocating Compressor is developed at Heat Pump Laboratory, stroke/bore 292 mm/32 mm. It is operated and tested successfully at different speeds for operational stability of components. Theoretical volumetric efficiency is 93.9% at pressure ratio 2.0. Specific energy consumption is 108.3 kWhe/m3 separated water, considering free run power.

    2017-09-20

    The emergence and diffusion of green and sustainable technologies is full of obstacles and has therefore become an important area of research. We are interested in further understanding the dynamics between entrepreneurial experimentation, market formation, and institutional contexts, together playing a decisive role for successful diffusion of such technologies. Accordingly, we study these processes by adopting a technological innovation system perspective focusing on actors, networks, and institutions as well as the functions provided by them. Using a qualitative case study research design, we focus on the high-speed flywheel energy storage technology. As flywheels are based on a rotating mass allowing short-term storage of energy in kinetic form, they represent an environmentally-friendly alternative to electrochemical batteries and therefore can play an important role in sustainable energy transitions. Our contribution is threefold: First , regarding the flywheel energy storage technology, our findings reveal two subsystems and related markets in which development took different courses. In the automotive sector, flywheels are developing well as a braking energy recovery technology under the influence of two motors of innovation. In the electricity sector, they are stagnating at the stage of demonstration projects because of two important system weaknesses that counteract demand for storage. Second , we contribute to the theory of technological innovation systems by better understanding the internal dynamics between different functions of an innovation system as well as between the innovation system and its (external) contextual structures. Our third contribution is methodological. According to our best knowledge, we are the first to use system dynamics to (qualitatively) analyze and visualize dynamics between the diverse functions of innovation systems with the aim of enabling a better understanding of complex and iterative system processes.

    Directory of Open Access Journals (Sweden)

    Jonas Kaiser

    2016-08-01

    Full Text Available This paper explores the integration of different social fields within the German Energy Transition (Energiewende discourse in the election year 2013 by analysing the hyperlink structures online. Energiewende describes the fundamental transition from non-renewable energy to sustainable sources. This goal is both ambitious and controversial. Numerous stakeholders try to make their voices and interests heard and as such politics has to both disseminate and collect information in order to include all relevant groups from different social fields in the political process. This discourse is also visible online. By analysing the hyperlink structures we are able to see the attention distribution of different actor groups in the network. This study shows that most actors tend to link within their own social field and do not aim for a more integrated public sphere. Especially political actors appear to be lone warriors who neither look left or right and mostly link within their own party and ignore other actors. Whereas social field as the media or public administration are relevant within the network we find that scientific actors are ignored by all fields, except for their own.

    2013-01-01

    Among the publications of CDC Climat Research, 'Climate Briefs' presents, in a few pages, hot topics in climate change policy. This issue addresses the following points: - Is the French energy transition compatible with economic growth and a 'competitive' French economy? Our answer is 'yes, with some conditions'. - The French economy is better positioned today for a meaningful energy transition than it has been for over 40 years. At the level of the macro-economy, a steady shift to higher energy prices is now much easier without hurting economic growth than it once was. - A small percentage of energy-intensive sectors may need targeted and temporary assistance with this transition

  1. Energy and Greenhouse Gas Emissions in China: Growth, Transition, and Institutional Change

    Science.gov (United States)

    Kahrl, Fredrich James

    support further improvements in efficiency and scale up renewable generation at an acceptable level of cost and reliability. Chapter 6 examines energy use and GHG emissions from nitrogen fertilizer use, arguing that energy use and GHG emissions from nitrogen fertilizer use in China are high relative to other countries because of China's historical support for small and medium-sized enterprises using domestic technology; its continued provision of energy subsidies to fertilizer producers; and its lack of a well-functioning agricultural extension system. The case studies illustrate the limits of energy and climate policy in China without institutional reform. China's leaders have historically relied on economic growth to defer the difficult changes in political economy that accompany economic and social transition. However, many of the challenges of energy and climate policy require political decisions that reallocate resources among stakeholders. For instance, restructuring the Chinese economy away from heavy industrial investment and toward a higher GDP share of consumption will require financial sector reforms, such as interest rate liberalization or higher dividend payments for state-owned enterprises, that reallocate income from the industrial sector to households. Increasing power system flexibility will require price reforms that reallocate revenues and costs among generators, between generators and the grid companies, between producers and ratepayers, among ratepayer classes, and between and among provinces. Strong public interest institutions are needed to make these changes, which suggests that China's energy and GHG emissions trajectories will be determined, to a large extent, by the politics of institutional reform.

  2. Energy indicators series: analyzing the energy-related evidence of economic transition in the Pacific Rim

    Paga, Enrique; Birol, Fatih

    1992-01-01

    In recent years, much attention has been focused upon the Asian Pacific countries as constituting an economic 'miracle' over the last two decades. Economic growth in the Pacific Rim has been higher than in any other area of the world. The rapid industrialization process and its impact on the economies of these countries, at both macro and micro levels, are discussed widely in the economic literature. Of particular interest are the fundamental structural changes these countries have experienced in their transition to industrialized economies. This instalment of the annual 'Energy indicators' series concentrates on Pacific Rim countries, namely Hong Kong, the Philippines, Singapore, South Korea, Taiwan and Thailand. Similar to other experiences, rapid economic growth in these countries has been accompanied by 'spectacular' growth in demand for energy. Therefore, this year's paper not only underlines certain trends in these six energy markets but also attempts to test the phenomenon 'threshold country', i.e., shifting from the developing to the industrialized world by using common indicators and methodologies. The analysis starts with a comparison of energy intensities. Section 2 provides an overview of the socio-economic and energy indicators of the Pacific Rim countries. Section 3 introduces a standard econometric model on the most dynamic consuming sector, namely transport. Section 4 presents the projections of consumption in this sector and discusses policy issues. Some concluding remarks in Section 6 complete the paper. (author)

  3. Massive financing of the energy transition - SFTE feasibility study: synthesis report, Energy renovation of public buildings

    International Nuclear Information System (INIS)

    2014-11-01

    The Energy Shift Financing Agency's (SFTE) project aims to establish a broad partnership between public and private entities to stimulate the economy and deliver between euros 180 bn and euros 420 bn of investment in Europe over 10 years for the benefit of medium-sized projects (in the order of euros 1 m) that are necessary for the energy transition. It will enable EU banks to finance the energy renovation of public buildings under excellent - cheap and long-term - conditions. A feasibility study has been conducted by the AFTER association with an exemplary consortium of public and private stakeholders in France: local authorities, industry players, banks/financial institutions, NGOs, Plan Batiment Durable. Many European institutions have expressed their interest in the initiative. Now the implementation of the SFTE project requires a commitment from European and national public authorities. Such a proactive real-estate policy would significantly contribute to economic recovery, cut costs, CO_2 emissions and the external deficit and improve energy independence, and could quickly create jobs. This document is the French version of the synthesis report of the SFTE project feasibility study. Two notes are attached to the document: one about the SFTE project adaptation to the Juncker's 315 bn euros investment plan, and the other about the selection of public buildings energy retrofitting in the Juncker plan and the French-German proposals

Prior to the Fukushima accident, the civil nuclear industry experienced two other major accidents: Three Miles Island (US, 1979) with limited and controlled impacts, and Chernobyl (USSR, 1986) with enormous impacts. The recent Japanese catastrophe has revived the questions concerning this risky technology. However, according to the IAEA, the civil nuclear energy should continue to develop in the future but in a more moderate way. Germany announced in June 2011 the shutdown of its last reactor by 2022, while France remained an exception until the Fukushima accident with a large political consensus among the general public in favor of nuclear energy. The nuclear phasing out or the energy transition is a complex question which is explored in this special issue. Content: 1 - The nuclear world: a moderate growth of the nuclear industry; interview of Mohamed ElBaradei, former head of IAEA; 441 reactors in operation in the world in January 2011; France has chosen the all-nuclear option; critics: a 'costly, unadapted, useless' nuclear program; interview of Valery Giscard d'Estaing, former French President; the nuclear industry actors; nuclear dismantling: a what cost?; how to manage the 250.000 tons of spent fuels; 2 - A risky technology: radioactivity measurement and effects; how to manage contaminations; four generations of reactors; ITER: a solar project; imagining the unimaginable and anticipating the worse; the wake up of a dozed off fear; the most important accidents: the progress of the three main nuclear catastrophes, the human mistake of Three Mile Island, the days after the Chernobyl accident, in the dead cities around Fukushima; interview of Kenzaburo Oe (Japanese writer); the Blayais power plant to the test; 3 - The energy transition: is France capable to abandon nuclear energy?; Germany is going to re-launch gas- and coal

    After having evoked some examples and studies (an assessment of the costs of energy storage, an industrial perspective for sodium-ion batteries, the development of an energy recovery system for road transport), a first article discusses the importance of a right definition of energy storage, of its functions and development framework (how to store, where to store, at which price, in which context). A second article evokes the installation of Forsee Power (a leader in battery assembly) in France. A third article discusses how to couple renewable energies and local energy storage. While evoking the example of the LMP battery by Bollore, a fourth article outline the common benefits of high capacity batteries used in electric vehicles as well as in domestic applications or renewable energy supply schemes. The fifth article proposes an overview of researches for the improvement of energy storage solutions (study of battery ageing, use of super-capacitors, thermal storage in industry, a hybrid storage of renewable energy in overseas districts, use of nano-silicon to improve anodes, improvement of oxygen supply in fuel cells, development of very porous silicon layers for anodes). The sixth article discusses the development of a process by Babcok and the Cnim Group for a massive storage of energy by thermal accumulation for electric or thermal energy producers. The seventh and last article notices that the IRENA (International renewable energy Agency) outlined the role of energy storage for the development of rural areas and of islands which are disconnected from the grid

  8. Energetic Communities: Planning support for sustainable energy transition in small- and medium-sized communities

    Full Text Available The necessity for transition in the energy sector is beyond dispute and high on the political agendas. Climate change, the depletion of fossil fuels and the vulnerability of economies to resource speculation and unreliable political systems in the producing countries lay path for a broad implementation of smart alternative solutions. This means the integration of more sustainable renewable energy sources in the existing supply structures or the displacement of existing systems by new ones. Cities and communities are central players in the energy transition process. Energy demand is determined by the built environment. Renewable energy production needs space. The conflicts between different interest groups often break out in the context of local implementation measures that affect urban planning and the appearance of landscapes. Small- and medium-sized communities might prove to be game-changers in the overall energy transition because many problems have to be solved within their ambit. Urban planning is dealing with the numerous processes of urban change. Energy is a fairly new task to be addressed and many stakeholders lack experience and criteria for strategic decision making. After a period of fierce determination to turn the wheel against climate change, it seems that there is a growing resignation among politicians, planners and the public because some things have not turned out the way we’d expected and the hope for quick solutions fades. Rebound-effects seem to eat up the savings to a good extent, and alternative ideas of how sustainable energy systems may be put into place have not yet been persuasive in many cases. Energy systems have proved to be complex. They are still perceived to be important but in practice there is a growing uneasiness about the right steps to take. The overarching research question of this thesis is: What do decision makers in smalland medium-sized communities need to become more successful in implementing

    Private and public organizations around the world are grappling with several challenging energy issues. In Canada, a recent poll showed that, despite the country's status as an energy exporter, citizens have mixed views on their energy literacy and influence over energy-related decision making. The energy endowment of Canada's varied regions partially explains these findings, but the overall picture is more complex. This research speaks to broader themes in the global energy dialogue such as the contributions of literacy to energy development, the role of public consultation in energy decision making and the value of money in motivating energy-efficiency behaviour.

    This document contains contributions presented by the GRTgaz general manager, the Danish ambassador, an expert in circular economy, the vice-chairman of the Danish gas and electricity utility, and a high representative of RTE about the role of energy transport networks in energy transition. It appears that energy transition raises several issues for energy transport operators: technical challenges due to the growth of renewable energies (notably in terms of grid steering and of production and consumption peak management), the introduction of flexibility and development of energy storage means, mechanisms of solidarity between regions and countries, political and economic dimensions with exchanges on good practices

    The energy transition represents a major opportunity to re-launch investment in Europe. According to the European Commission and the International Energy Agency, more than 100 billion of euros of investment per year will be necessary to attain the ambitious climatic objectives. To accelerate investment in the energy transition, the European Union will have to adopt objectives that rely partly on voluntary action and mobilise financing sources. (author)

  13. Off-energy-shell variations of two-nucleon transition matrix and three-nucleon problem

    1975-01-01

    For a schematic three-nucleon problem, approximate analytic expressions are derived for the functional derivatives of measurable three-particle quantities with respect to off-shell variations of the triplet-s two-nucleon transition matrix. Those quantities include neutron-deuteron scattering lengths, trinucleon binding energies, and the 3 He charge form-factor minimum; correlations between off-shell changes in the latter two are discussed. An indication is given how results of this kind may be to decide whether or not a given set of discrepancies between calculated and experimental three-nucleon observables can be reconciled in terms of off-shell variations of a nonretarded hermitean two-nucleon interaction. The treatment is not restricted to special classes of phase-shift equivalent potentials or phase-shift preserving transformations but instead makes use of a systematic parameterization of off-shell variations in terms of symmetric rational approximants of increasing order

  14. Theoretical potential for low energy consumption phase change memory utilizing electrostatically-induced structural phase transitions in 2D materials

    Structural phase-change materials are of great importance for applications in information storage devices. Thermally driven structural phase transitions are employed in phase-change memory to achieve lower programming voltages and potentially lower energy consumption than mainstream nonvolatile memory technologies. However, the waste heat generated by such thermal mechanisms is often not optimized, and could present a limiting factor to widespread use. The potential for electrostatically driven structural phase transitions has recently been predicted and subsequently reported in some two-dimensional materials, providing an athermal mechanism to dynamically control properties of these materials in a nonvolatile fashion while achieving potentially lower energy consumption. In this work, we employ DFT-based calculations to make theoretical comparisons of the energy required to drive electrostatically-induced and thermally-induced phase transitions. Determining theoretical limits in monolayer MoTe2 and thin films of Ge2Sb2Te5, we find that the energy consumption per unit volume of the electrostatically driven phase transition in monolayer MoTe2 at room temperature is 9% of the adiabatic lower limit of the thermally driven phase transition in Ge2Sb2Te5. Furthermore, experimentally reported phase change energy consumption of Ge2Sb2Te5 is 100-10,000 times larger than the adiabatic lower limit due to waste heat flow out of the material, leaving the possibility for energy consumption in monolayer MoTe2-based devices to be orders of magnitude smaller than Ge2Sb2Te5-based devices.

    Scrutiny and careful study in energy is a subject that in human science has been investigated from different point of view. The expansion of this research, because of its importance and effect in different dimensions of human life, has also arrived in the field of political and economic sciences. Economics evaluates the energy phenomenon at the side of elements such as labor, capital and technology in the production functions of firms. The nature of these discussions is mainly from the viewpoint of micro analyses. Nevertheless, the variation and challenges concerning energy and environment during the recent decades and the economists` detailed investigations in its analysis and evaluation have led to the arrival of energy discussions in a special shape in macro planning and large economic models. The paper compares various energy models - EFDM, MEDEE, MIDAS and HERMES. This extent of planning and consequently modelling which lacks a background in the processes of economic researches, deals with analysis of energy and economics reacting effects. Modelling of energy-economy interaction and energy policy in modeling macroeconomics large models are new ideas in energy studies and economics. 7 refs., 6 figs., 1 tab.

    Twenty-first century access to energy sources depends on a complex system of global markets, vast cross-border infrastructure networks, a small group of primary energy suppliers, and interdependencies with financial markets and technology. This is the context in which energy security has risen high on the policy agenda of governments around the world and the term 'energy security' has quietly slipped into the energy lexicon. The limited discourse about the nature of the term or its underlying assumptions has been totally eclipsed by an almost overwhelming focus on securing supplies of primary energy sources and geopolitics. An examination of explicit and inferred definitions finds that the concept of energy security is inherently slippery because it is polysemic in nature, capable of holding multiple dimensions and taking on different specificities depending on the country (or continent), timeframe or energy source to which it is applied. This 'slipperiness' poses analytical, prediction and policy difficulties but if explicitly recognised through definitional clarity, new levels of understanding will enrich the policy debate to deal with obstacles impacting on the constantly evolving nature of energy security.

    This document reports a study which aimed at a better understanding of energy transition strategies in Germany, Spain and United Kingdom. It outlines that these strategies are different and give contrasted results, that economic implication of energy transition programmes are also different. Two financing approaches are identified (mainly by private investors, or by mobilizing all types of financial support), and therefore two economic strategies (productivity-oriented investments, or search for a structural competitiveness with a new growth model). The report notices that there is no reference study of the impact of energy transition on employment

    The transition to renewable energy technologies raises new and important governance questions. With small hydropower (SHP) expanding as part of renewable energy and climate mitigation strategies, this review assesses its impacts and identifies escalating policy issues. To provide a comprehensive literature review of small hydropower, we evaluated over 3600 articles and policy documents. This review identified four major concerns: (1) confusion in small hydropower definitions is convoluting scholarship and policy-making; (2) there is a lack of knowledge and acknowledgement of small hydropower’s social, environmental, and cumulative impacts; (3) small hydropower’s promotion as a climate mitigation strategy can negatively affect local communities, posing contradictions for climate change policy; and (4) institutional analysis is needed to facilitate renewable energy integration with existing environmental laws to ensure sustainable energy development. For readers interested in small hydropower, we clarify areas of confusion in definition and explain the corresponding impacts for distinct system designs. For a broader readership, we situate small hydropower implementation within international trends of renewable energy development – the contradictory impacts of climate change policy, emerging dynamics in energy finance, and reliance on market mechanisms. Our paper provides a timely contribution to scholarship on small hydropower and the transition to renewable energy. - Highlights: • Confusion in small hydropower definitions is convoluting small hydropower debates. • Small hydropower’s negative impacts are largely overlooked in policy discussions. • Small hydropower exemplifies paradoxical problems with climate change policy. • Policies needed to integrate renewable energy development with national environmental institutions.

    Among the publications of CDC Climat Research, 'Climate Reports' offer in-depth analyses on a given subject. This issue addresses the following points: The Regional Climate-Air-Energy Plan (SRCAE - Schema Regional Climat-Air-Energie) was introduced by the Grenelle II legislation. The Plans are co-authored by the State through its decentralised services and the 'Conseil Regionaux' (regional councils) with the objective to guide climate and energy policy in the 26 French regions through to 2020 and 2050. Starting from an assessment of regional greenhouse gas (GHG) emissions, the SRCAE establishes energy transition scenarios based on the sectoral and structural guidelines that constitute the principal framework of the regional strategy. This report offers a detailed analysis of the strategies chosen by the various Regions for a successful transition to low-carbon energy sources, via the study of eleven SRCAEs that were opened to public consultation before the end of July 2012 (Alsace, Aquitaine, Auvergne, Bourgogne, Centre, Champagne-Ardenne, Ile-de-France, Midi-Pyrenees, Nord-Pas de Calais, Picardie and Rhone-Alpes regions). The wide range of methodologies used by the Regions, both to draw up their inventories of GHG emissions and for their scenarios, means that a quantitative comparison between regions or against the national objectives is not possible. Nevertheless, the report establishes a typology of regions and identifies policies that are common to all regions and those chosen in response to local characteristics. Certain guidelines could be applied by other regions of the same type, or could feed into discussions at national level. The report also indicates that the SRCAEs go beyond the competencies of the Regions, highlighting the role of local, national and European decision-making in the success of a regional energy transition. Particular attention was paid to the building and transport sectors, often identified as having the largest potential for reducing

    Studies of the Siberian Energy Institute, Irkutsk, and the Nuclear Research Center, Juelich, carried out with the aid of complex computer models, demonstrate the opportunities of novel integrated energy systems in a future, clean energy supply. As conditions differ widely in different regions and different countries, there will of course be a wide structural variety in the realization of integrated energy systems. The studies of SEI and KFA, based on the cooperation with the International Institute of Applied System Analysis (IIASA), emphasize the common viewpoint that the idea of integrated energy systems constitutes an essential basis for future studies on 'energy in a finite environment'.

    The EU energy policy aims at creating a single European electricity market through market couplings and grid expansions. To analyse the implications of such power market couplings, we propose a market-based multi-region energy system model. The model simulates a multi-region power market (by applying market optimization and network theory), with detailed representation of each region as an energy system (by simulation of both heat and power sectors). We examine the impact of further integration of variable renewable energy (VRE) in Germany on the Nordic power market. The results indicate that the average electricity price slightly grows in the Nordic power market after Germany's Energy Transition (Energiewende). Hence, the economic surplus of Nordic consumers diminishes while Nordic producers improve their gain under new market conditions. Considering the gird congestion income, the overall system-level benefits (social welfare) will improve in the Nordic region after Germany's Energiewende. However, this gain is not equally distributed among different Nordic countries and across different stakeholders. Furthermore, the Energiewende slightly increases carbon emissions from power and district heating (DH) sectors, and reduces the flexibility in integration of VRE in some Nordic countries like Denmark. The direct interconnection of Norway and Germany through NordLink will contribute to the flexibility in wind integration in other Nordic countries, such as Denmark and Finland. - Highlights: • By an integrated hourly analysis, we model the energy systems of several networked countries and their common electricity market. • The proposed model can inform energy policy on implications of renewable energy integration in an international power market. • Among Nordic countries, Norway gains the highest economic benefits from Germany's energy transition. • Germany's energy transition constrains the flexibility of the Nordic countries in wind integration. • Nord

    The French law on the energy transition and green growth (TECV law) seems in some ways limited in scope, restricted to set vague goals and formulate simple incentives to act. But this law can not be reduced to this. Composed of 215 articles, it necessarily refers to prescriptive and technical measures meant to realize the energy transition. The TECV law has, moreover, the merit of addressing the energy issue in its entirety, evoking not only renewable energies, but also the insulation of buildings, the challenge of developing clean transport, the need to promote a circular economy that consumes less energy

  7. Large impact of reorganization energy on photovoltaic conversion due to interfacial charge-transfer transitions.

    2015-05-14

    Interfacial charge-transfer (ICT) transitions are expected to be a novel charge-separation mechanism for efficient photovoltaic conversion featuring one-step charge separation without energy loss. Photovoltaic conversion due to ICT transitions has been investigated using several TiO2-organic hybrid materials that show organic-to-inorganic ICT transitions in the visible region. In applications of ICT transitions to photovoltaic conversion, there is a significant problem that rapid carrier recombination is caused by organic-inorganic electronic coupling that is necessary for the ICT transitions. In order to solve this problem, in this work, I have theoretically studied light-to-current conversions due to the ICT transitions on the basis of the Marcus theory with density functional theory (DFT) and time-dependent DFT (TD-DFT) calculations. An apparent correlation between the reported incident photon-to-current conversion efficiencies (IPCE) and calculated reorganization energies was clearly found, in which the IPCE increases with decreasing the reorganization energy consistent with the Marcus theory in the inverted region. This activation-energy dependence was systematically explained by the equation formulated by the Marcus theory based on a simple excited-state kinetic scheme. This result indicates that the reduction of the reorganization energy can suppress the carrier recombination and enhance the IPCE. The reorganization energy is predominantly governed by the structural change in the chemical-adsorption moiety between the ground and ICT excited states. This work provides crucial knowledge for efficient photovoltaic conversion due to ICT transitions.

    Easy energy access is a trigger for human, social, and economic development. A research project was undertaken in Sri Lanka to broaden the understanding of human dimension of energy access and technologies. A questionnaire survey, covering 2269 households, gathered data on socio-economic contexts and issues influencing a transition towards clean cooking facilities. The findings reveal that the transition is impeded by four factors: the lack of motivation and the pressure for switching over to cleaner facilities, the lack of modern energy technology options, the financial risks, and the lack of financing and other support. The paper describes the delicate two-way interrelation between women earning wages and the transitions to cleaner cooking fuels and technologies. The findings suggest the need for a policy framework involving the stakeholders, financing and standardised technologies. To make a change it is proposed to introduce a national, integrated policy incorporating financing and energy governance. - Highlights: ► Households in Sri Lanka lack access to modern energy technology options for cooking. ► Cooking with fuel wood and residues is the norm in Sri Lanka, particularly in rural households. ► A survey of rural households revealed that most cannot afford to switch to cleaner cooking options. ► Most households have little awareness of the health impacts of biomass cooking. ► Women in regular formal employment are more likely to value cleaner cooking options that save time.

    The conversion of the German electricity supply system to production from renewable resources under the national energy transition policy is making it necessary to expand and restructure the distribution networks. Based on the expansion goals of the federal government, expectations are that thinly populated regions with low conflict potential will see a continued growth in distributed generation. This will increase the geographic asymmetry that exists between the production of renewable energy in rural, peripheral regions and its consumption predominantly in urban regions, thus enlarging the regional differences in system usage charges seen already today. The geographic disparity between production and consumption may grow larger still with the continuing installation of new and repowering of existing renewable energy plants. Of the possibilities discussed so far for reforming the scheme of charges, some would only have a weak impact, while others would even exacerbate the problem. The solution proposed in the present article takes account of the costs incurred through upstream supply networks in accordance with Article 14 Section 1 Sentence 1 of the Ordinance on System Usage Charges. In effect it leads to an allocation of costs according to the user-pays principle, thus protecting consumers connected to rural distribution networks against an undue cost burden and charging a fair share of the costs to consumers in urban and industrial distribution networks.

    Energy has become a commodity with economic price in Slovakia. For years the energy price has not fulfilled the basic economic criteria - covering of production costs. It was used as one of the instruments of Governments social policy. But the situation is changing. Another phase of bringing the prices to a realistic level brought along a price increase by tens of percents. As the energy prices are increasing and there is a perspective that they will grow further all possible reserves and cheaper energy sources have to be identified. A simplified energetic model of Slovak economy identifies three basic energy-consumer kinds - industry, buildings and transport. Industry uses about one half of the Slovakia's yearly energy-consume. Aim private companies to survive in a competitive environment guarantees of a rational approach towards energy consume. The fact that even in companies that use high volumes of primary raw material the energy consume is the highest cost item (many times higher then the labour costs) is the main incentive for looking for saving possibilities in this area. A decrease of the industries' share in energy consume may indicate some positive trends. The energy consume in industries has dropped by ten percent within ten years and its share on the overall consume is approaching the 45-percent level. This was partially caused by decreasing production volumes or closing down of production in several companies. Energy consume of buildings represents about 35 - 40 percent of the national consume i.e. is on a level similar to other European countries. This is a sector is the most important. It is its structure that is important. Currently there are 1,8 million flat units in Slovakia. Family houses represent 48 percent and the remaining 52 percent go to flats.

    2014-12-01

    Full Text Available This paper integrates several streams of literature in transition management and proposes a holistic framework for its application in policy-making. Separate fields of study, such as motors of change and strategic intelligence tools, are unified in a single analytical process. The process involves five steps that may be repeated until a desired policy objective is achieved. The pilot, integrated technology roadmap process that has been launched in Turkey is analyzed as a case study. The Energy Efficiency Technology Roadmap has been completed with the participation of over 160 experts in 5 different stages. It involved the collection of over 349 Delfi statements, their consolidation for a Delfi survey with 16 statements, the analysis of the results, a focal group meeting to develop roadmaps for the 7 selected goals, and the consultation of the roadmaps to the sector. The paper concludes that an integrated technology roadmap process, as described in the pilot case study, provides an advanced version of transition management, which is needed to mobilize research, development, and innovation for sustainable development.

    This history of the transition from organic to mineral fuels suggests a number of conclusions that may have parallels in the future: People respond to price incentives; science is important but not sufficient; human capital is important; cooperation is as important as competition; path breaking technologies take a long time to mature. The future, however, will not – and should not! – be a replay of the past. One of the greatest differences is the externality issues raised by global warming. The choice of fuels and technologies has ramifications far beyond the profit and loss statements of the people deciding them. In that case, decentralized decision making will not reach a desirable overall result. Planning and coordination are essential to tackle these problems. - Highlights: ►This paper focuses on the first energy transition from animal, water, wind, and fire wood to coal. ►It was driven by prices, and required new technology. ►It depended on human capital and scientific discovery, and on cooperation.

  19. The energy transition: new dialogues between cities and local stakeholders. Exploratory study

    2016-01-01

    Energy Cities has carried out an exploratory study for cities and diverse project leaders desiring to start a sustainable energy transition in collaboration with all stakeholders in their territory. Local authorities have a key role to play in climate and energy policies and in the energy transition towards a low carbon, energy efficient and sustainable society. However, they cannot act alone. They often control only a small percentage of the emissions of local greenhouse gases directly, and this percentage rarely exceeds a quarter. It is therefore necessary to rely on the involvement of local stakeholders, which in turn will provide an opportunity for these stakeholders to be ambitious through innovative actions. How to stimulate stakeholders' involvement? In the past several years, a number of citizens', economic actors' or other local actors' initiatives have contributed to the energy transition of territories. These initiatives are based on empowerment. For instance, stakeholders can get access and the power to act on innovative tools and approaches, such as social economy, stakeholders' participation, crowd-funding, renewable energy citizen cooperatives and fab labs. Two primary questions to explore: As coordinators and pilots of local strategies for energy transition, how can local authorities foster, identify, support and replicate local energy transition initiatives? What dialogue should local authorities and leaders of local initiatives engage in? How can they drive new modes of governance, where stakeholders share responsibility to co-develop public policies, manage their city, and encourage the energy transition at the local level? We selected more than ten European energy transition initiatives, as diverse as they are innovative, anticipating new forms of governance and new ways to act and collaborate. The exploratory study does not only describe their process but it also analyses the synergies between the different stakeholders and the role the

  1. The slow search for solutions: Lessons from historical energy transitions by sector and service

    International Nuclear Information System (INIS)

    Fouquet, Roger

    2010-01-01

    This paper reviews past energy transitions by sector and service to identify features that may be useful for future transitions. Although often considered a single event, the transition from traditional energy sources to fossil fuels involved numerous services and sectors at different times between 1500 and 1920. The main economic drivers identified for energy transitions were the opportunities to produce cheaper or better energy services. The existence of a niche market willing to pay more for these characteristics enabled new energy sources and technologies to be refined gradually until they could compete with the incumbent energy source. Nevertheless, this implied that, on average, the whole innovation chain took more than 100 years and the diffusion phase nearly 50 years. In the same way, low-carbon energy sources and technologies offer an additional characteristic (i.e. low carbon impact), which might be able to develop gradually in a niche market until they can compete with fossil fuels. However, because of consumers' tendency to free-ride, a successful transition will need governments to provide protection of this niche market-possibly for decades. Based on past experiences, a complete transition to a low carbon economy is likely to be very slow.

  2. Serious simulation game development for energy transition education using integrated framework game design

    2017-11-01

    Due to the advantages that serious simulation game offered, many areas of studies, including energy, have used serious simulation games as their instruments. However, serious simulation games in the field of energy transition still have few attentions. In this study, serious simulation game is developed and tested as the activity of public education about energy transition which is a conversion from oil to natural gas program. The aim of the game development is to create understanding and awareness about the importance of energy transition for society in accelerating the process of energy transition in Indonesia since 1987 the energy transition program has not achieved the conversion target yet due to the lack of education about energy transition for society. Developed as a digital serious simulation game following the framework of integrated game design, the Transergy game has been tested to 15 users and then analysed. The result of verification and validation of the game shows that Transergy gives significance to the users for understanding and triggering the needs of oil to natural gas conversion.

    2011-01-01

    This article deals with the challenge of approaching decision-making processes through strategic environmental assessment (SEA). It is argued that the interaction between policy-making and planning in strategic decision-making processes is a neglected reason for problems with applying SEA......, as legislation and guidance on SEA primarily approach either the policy or plan level. To substantiate the argument, the extent of interaction is empirically investigated. Four contemporary decision-making processes in the Danish energy sector are mapped as a series of choices. Fundamental changes...... with considerable environmental impacts are decided these years, often without preceding SEA processes. The mapping shows a profound interaction between policy-making and planning. In this interaction, public consultation, systematic environmental analyses, and transparency on alternatives are primarily related...

    2014-01-01

    Graphical abstract: Size dependent surface free energy of spherical, cubic and disk Au nanoparticles. - Highlights: • A model to account for the surface free energy of metallic nanoparticles is described. • The model requires only the cohesive energy of the nanoparticle. • The surface free energy of a number of metallic nanoparticles has been calculated, and the obtained values agree well with existing data. • Surface energy falls down very fast when the number of atoms is less than hundred. • The model is applicable to any metallic nanoparticle. - Abstract: This paper addresses an interesting issue on the surface free energy of metallic nanoparticles as compared to the bulk material. Starting from a previously reported equation, a theoretical model, that involves a specific term for calculating the cohesive energy of nanoparticle, is established in a view to describe the behavior of surface free energy of metallic nanoparticles (using different shapes of particle: sphere, cube and disc). The results indicate that the behavior of surface energy is very appropriate for spherical nanoparticle, and thus, it is the most realistic shape of a nanoparticle. The surface energy of copper, silver, gold, platinum, tungsten, molybdenum, tantalum, paladium and alkali metallic nanoparticles is only prominent in the nanoscale size, and it decreases with the decrease of nanoparticle size. Thus, the surface free energy plays a more important role in determining the properties of nanoparticles than in bulk materials. It differs from shape to another, and falls down as the number of atoms (nanoparticle size) decreases. In the case of spherical nanoparticles, the onset of the sharp decrease in surface energy is observed at about 110 atom. A decrease of 16% and 45% in surface energy is found by moving from bulk to 110 atom and from bulk to 5 atom, respectively. The predictions are consistent with the reported data

  8. Making the results of bottom-up energy savings comparable

    Directory of Open Access Journals (Sweden)

    Moser Simon

    2012-01-01

    Full Text Available The Energy Service Directive (ESD has pushed forward the issue of energy savings calculations without clarifying the methodological basis. Savings achieved in the Member States are calculated with rather non-transparent and hardly comparable Bottom-up (BU methods. This paper develops the idea of parallel evaluation tracks separating the Member States’ issue of ESD verification and comparable savings calculations. Comparability is ensured by developing a standardised BU calculation kernel for different energy efficiency improvement (EEI actions which simultaneously depicts the different calculation options in a structured way (e.g. baseline definition, system boundaries, double counting. Due to the heterogeneity of BU calculations the approach requires a central database where Member States feed in input data on BU actions according to a predefined structure. The paper demonstrates the proposed approach including a concrete example of application.

    Kiss, Anton A.; Flores Landaeta, Servando J.; Infante Ferreira, Carlos A.

    2012-01-01

    In spite of claiming around half of the operational costs of chemical plants, distillation is still the most popular separation technology. Distillation has low thermodynamic efficiency, requiring the input of high quality energy in the reboiler – while rejecting a similar amount of heat at lower temperature, in the condenser. Several heat pump concepts have been proposed to upgrade that thermal energy and reduce the consumption of valuable utilities. Under certain conditions, the energy savings of heat pump assisted distillation is usually around 20–50%. This study proposes a novel selection scheme of energy efficient distillation technologies, with a special focus on heat pumps. The most promising technologies selected are vapor compression, mechanical or thermal vapor recompression, absorption, compression–resorption and thermo-acoustic heat pumps, multi-effect distillation, heat integrated distillation column, cyclic distillation, Kaibel and dividing-wall column. The scheme considers as the main selection criteria the type of separation tasks, product flow and specifications, operating pressure, difference in boiling points, reboiler duty and its temperature level. Moreover, this scheme is very practical, allowing major time and resources savings in the design of eco-efficient processes. -- Highlights: ► Heat pump assisted distillation with energy savings of 20–50%. ► Novel and practical selection scheme of energy efficient distillation technologies. ► Evaluation of promising technologies: VC, MVR, TVR, AHP, CHRP, TAHP, HIDiC, DWC, CyDist. ► Selection criteria include: ΔT b , ΔT lift , P, T reb , Q reb , volatility. ► Design of eco-efficient processes with high COP, and lower TIC and TAC.

    2013-06-01

    This report summarises the outcomes of a 30 months duration continuing education project entitled 'Urban Planners with Renewable Energy Skills' (UP-RES). The project was carried out by a multi-disciplinary international consortium with the aim of informing planners and related professionals about energy-efficient and CO{sub 2} reducing technologies, practices and systems that can be developed across urban areas to serve whole communities. This report provides an overview of the key issues: The overall project approach to devising a training program based on preceding training needs analysis The key tasks involved in creating the training materials The marketing of the training as well as evaluation results Best practise examples of RES in urban planning. The UP-RES project has focused on several major target groups. These include those groups directly involved in taking forward renewable energy projects for whom the UP-RES training was principally focused; those who wish to deliver such training programmes; and policy makers who are ultimately responsible for the decisions that govern how widely such technologies will be implemented. Each of these groups has its own perspective concerning renewable energy technologies so the report is structured accordingly: For professionals involved in implementation: Among those professions that are likely to become involved with renewable energy initiatives in urban areas are urban planners, architects, energy suppliers, developers, building owners, and consulting engineers. For these professionals chapters 3.2 (summary of training need analysis) and 4 (best practise examples) are most likely to appeal. For training experts and organisations: Training programmes that address the relevance of renewable energies in urban areas require a comprehensive set of materials. As an example of how to organise training courses and lessons learnt, chapter 3 might be interesting. For the generally interested: Renewable energies are

    Electric monopole (E0) properties are studied across the entire nuclear mass surface. Besides an introductory discussion of various model results (shell model, geometric vibrational and rotational models, algebraic models), we point out that many of the largest E0 transition strengths, $\\rho^2$(E0), are associated with shape mixing. We discuss in detail the manifestation of E0 transitions and present extensive data for~: single-closed shell nuclei, vibrational nuclei, well-deformed nuclei, nuclei that exhibit sudden ground-state changes, and nuclei that exhibit shape coexistence and intruder states. We also give attention to light nuclei, odd-A nuclei, and illustrate a suggested relation between $\\rho^2$(E0) and isotopic shifts.

    Directory of Open Access Journals (Sweden)

    2016-01-01

    Full Text Available Now, more and more mobile smart devices are emerging massively; energy consumption of these devices has become an important consideration due to the limitation of battery capacity. Displays are the dominant energy consuming component of battery-operated devices, giving rise to organic light-emitting diode (OLED as a new promising display technology, which consumes different power when displaying different content due to their emissive nature. Based on this property, we propose an approach to improve image energy efficiency on OLED displays by perceiving image content. The key idea of our approach is to eliminate undesired details while preserving the region of interest of the image by leveraging the color and spatial information. First, we use edge detection algorithm to extract region of interest (ROI of an image. Next, we gradually change luminance and saturation of region of noninterest (NON-ROI of the image. Then we perform detailed experiment and case study to validate our approach; experiment results show that our approach can save 22.5% energy on average while preserving high quality of the image.

    The fall of communism left some of the most polluting and wasteful energy sectors of the World in Central and Eastern Europe (CEE). After 15 years of restructuring, eight of these countries have joined the European Union (EU), closing an era of economic transitions. What progress has been made in these countries in the field of energy from the perspective of sustainability? Has the transition agenda been completed, or do any of the socialist energy sector legacies prevail? The purpose of this paper is to review the period of economic transition in the energy sector, focusing on sustainability, in three selected CEE countries, and to use Russia as a comparison. First, the paper argues that at the core of the unsustainability of energy sectors at the end of the communist era were among the highest energy intensities in the world. Then, we identify the legacies of the centrally planned economy that contributed to these high-energy intensities. We outline a policy agenda for the transitions which addresses the identified legacies. Next, we look at the energy landscape at the end of the restructuring, and review the developments in energy intensities during the period of economic transitions. We conclude that, while energy and economic restructuring is very important to bring down the high-energy intensities of former communist countries, a sizeable gap remains in intensity levels between CEE countries and the old EU states. Therefore, economic and energy system reforms alone will not close the gap, and targeted policies and measures are needed to improve energy efficiency levels. Beyond a more serious governmental commitment, a concerted effort is needed from regulators, corporations, utilities, consumer organisations and the civil sector to catalyse the remaining progress to be made in combating the socialist legacy in the field of energy efficiency

    This publication reviews and criticises some received ideas or myths about energy transition in Germany. These received ideas state that this energy transition is only based on phasing out nuclear (whereas it is a comprehensive political project which goes beyond this phasing out and the development of renewable energies, notably with a high objective in terms of greenhouse gas emissions), that the development of renewable energies resulted in a strong increase of household energy bills (whereas German households tend to consume less energy), that Germany had to rely on coal and give up its objectives in the struggle of climate change (whereas renewable energies, not coal, replaced nuclear energy, and coal in fact replaced gas which became too expensive), that the German economy can face energy transition when French economy cannot (whereas the German energy transition is designed to be a benefit for the German economy), and that the money of German consumers was only used to enrich Chinese photovoltaic array manufacturers (whereas 4/5 of the installation added value is created on the German territory)

    2011-08-18

    Using density functional theory calculations we show that the adsorption energies for C{sub 2}H{sub x}-type adsorbates on transition metal surfaces scale with each other according to a simple bond order conservation model. This observation generalizes some recently recognized adsorption energy scaling laws for AH{sub x}-type adsorbates to unsaturated hydrocarbons and establishes a coherent simplified description of saturated as well as unsaturated hydrocarbons adsorbed on transition metal surfaces. A number of potential applications are discussed. We apply the model to the dehydrogenation of ethane over pure transition metal catalysts. Comparison with the corresponding full density functional theory calculations shows excellent agreement.

    This publication further develops the analysis presented in the India chapter of Energy Technology Perspectives 2010 and provides insights on the implications of achieving deep energy and CO2 emission cuts in the industrial sector both for India and globally. It investigates the least-cost combination of options that can significantly reduce energy and CO2 emissions in India's industrial sector, while enabling the Indian economy to continue to grow and alleviate energy poverty. For India to play its part in helping to realise deep cuts in global CO2 emissions by the middle of the 21st century, it will need to achieve rapid economic development over the next 40 years with only a very small increase in emissions. Currently there is no precedent for such a low-CO2 development path. The challenge for India will be to achieve strong economic growth while improving energy security, but without locking in high emissions.

    Since 1960 the Soviet Union has been, for all practical purposes, Cuba's exclusive supplier of energy products. For certain time periods, Soviet sales of oil and oil products to Cuba were made at concessional prices; prior to 1991, they were priced using transferable rubles and were essentially bartered for Cuban goods, especially sugar. Effective January 1, 1991, the Soviet Union shifted to world market prices and convertible currency payments for all traded commodities, including energy products. The shift to market prices and convertible currencies in Cuban-Soviet energy trade has already brought - or is likely to bring - a number of adjustments in four areas: (1) the trade balance; (2) the ability to reexport oil and oil products; (3) energy consumption patterns; (4) and the structure of energy supplies. 33 refs., 8 tabs

  11. Energy in transition 1985 to 2010: overview. Final report

    Energy Technology Data Exchange (ETDEWEB)

    1979-01-01

    This study by the Committee on Nuclear and Alternative Energy Systems (CONAES) examines in detail all aspects of the nations energy situation. Some technical and economic observation that decision makers may find useful as they develop energy policy in the larger context of the future of society are offered. The observations focusing on the prime importance of energy conservation; the critical near-term problem of fluid fuel supply; the desirability of a balanced combination of coal and nuclear fission as the only large-scale intermediate-term options for electricity generation; the need to keep the breeder option open; and the importance of investing now in research and development to ensure the availability of a strong range of new energy options sustainable over the long term are discussed in detail.

    2018-01-01

    The study adopts a multi-level perspective in technology transition to analyse how the transition process in the development of geothermal energy in Indonesia is able to compete against the incumbent fossil-fuelled energy sources. Three levels of multi-level perspective are socio-technical landscape (ST-landscape), socio-technical regime (ST-regime) and niche innovations in Indonesia geothermal development. The identification, mapping and analysis of the dynamic relationship between each level are the important pillars of the multi-level perspective framework. The analysis considers the set of rules, actors and controversies that may arise in the technological transition process. The identified geothermal resource risks are the basis of the emerging geothermal technological innovations in Indonesian geothermal. The analysis of this study reveals the transition pathway, which yields a forecast for the Indonesian geothermal technology transition in the form of scenarios and probable impacts.

  13. Hydrogen as a link between sustainable mobility and transition of the German energy system

    Even 15 years ago, the predictions with regard to the market penetration of fuel cell automobiles or of so-called fuel cell heaters were communicated with differing statements. Daimler Benz AG, as it still was back then, had put their faith in the rapid integration of a fuel cell into the vehicle, whereas companies such as Vaillant, Hamburger Gas Consult, Sulzer Hexis or even MTU and Siemens were working on stationary fuel cell systems. The expectations at that time with regard to market and technology development have still not yet been fulfilled. Today, the subject has been given a new lease of life thanks to the public discussions regarding the energy transition and the current framework conditions. Many concepts that have already been under consideration, but which very few have considered realistic in the short-term, now appear at least to have come within reach. As a result of the fluctuations in the generation of renewable energies, Germany needs loads that can be switched and, above all, methods of storing energy. In conjunction with new technologies, such as PEM electrolysis and the pressure which has been put on politics to react and to create the necessary framework conditions, a new momentum has developed with regard to the use of hydrogen. This article analyses to what extent synergies between energy transition and mobility can be expected within the context of hydrogen. With a view to quantity, times and local relationships, quality and price, we have been able to determine that the relevant amounts and dependencies have a positive and relevant magnitude to one another, thus synergies are present. It should be noted that hydrogen will not be the sole solution for the Federal Government when it comes to achieving CO{sub 2} reduction aims. Electrical mobility with approaches for bidirectional charging, new storage technologies and alternative energy carriers, switchable loads as well as the local public transport systems and new mobility concepts will

    This report is the part concerning Central and Eastern Europe (CEE) and the Commonwealth of Independent States (CIS) of the World Energy Council (WEC) Programme - a global study of the financing requirements of future energy developments. The investment needs are determined to reach the standards of developed energy market economies in terms of quality of service, efficiency, profitability, environmental protection and safety. Considering the macro-economic and general energy development scenarios done by IIASA and WEC the cumulative investment requirements 1990-2020 would be to range from $281bill. to $509 bill. in CEE; annual investment requirements would amount to $15-28 bill. depending on the scenarios; specific investment requirements per ton energy would range from 77 (ecologically driven scenario) to $101 (high growth, coal based scenario). In 1994 international finance for CEE/CIS energy sector was only $5 bill. (or 5% of the needs) due to the small size of the projects, low energy prices and the lack of incentives. CEE/CIS countries have not done enough to attract foreign loans. Western energy corporations acquired shares of Russian oil and gas companies. Reasons for the slow start include currency risk, legal uncertainty, uncertain demand prospects, low electricity tariffs, required rate of returns - above 18% in CEE, 25% in CIS, compared to 10% in US and UK. About 9% of total world foreign direct investments have been entered in energy sector. Multilateral organizations have invested yearly average $0.8-1 bill. grants and credits in CEE/CIS energy activities. From 1991 to 1995 135 mill. ECU have been spent for supporting national energy sector in CEE countries under PHARE activities. Difficulties are due to the lack of developed capital markets in these countries. In the future CEE capital markets could support a substantial proportion of the national investment requirements. By 2020 capital requirements for energy supply investments would be 3.4-4.7% of

  17. Contestation, contingency, and justice in the Nordic low-carbon energy transition

    The five Nordic countries have aggressive climate and energy policies in place and have already emerged to be leaders in renewable energy and energy efficiency. Denmark is renowned for its pioneering use of wind energy, Finland and Sweden bioenergy, Norway hydroelectricity and Iceland geothermal energy. All countries aim to be virtually “fossil free” by 2050. This study explores the Nordic energy transition through the lens of three interconnected research questions: How are they doing it? What challenges exist? And what broader lessons result for energy policy? The study firstly investigates the pathways necessary for these five countries to achieve their low-carbon goals. It argues that a concerted effort must be made to (1) promote decentralized and renewable forms of electricity supply; (2) shift to more sustainable forms of transport; (3) further improve the energy efficiency of residential and commercial buildings; and (4) adopt carbon capture and storage technologies for industry. However, the section that follows emphasizes some of the empirical barriers the Nordic transition must confront, namely political contestation, technological contingency, and social justice and recognition concerns. The study concludes with implications for what such historical progress, and future transition pathways, mean for both energy researchers and energy planners. - Highlights: • Nordic countries have strong energy and climate policies to be practically “fossil free” by 2050. • Decarbonization and transition pathways depend on renewable energy, efficiency, transport, and industry. • The Nordic transition remains contingent on further technological innovations and policy commitments. • It also raises energy justice issues concerning employment, public knowledge, and embodied emissions.

  18. Winding transitions at finite energy and temperature: An O(3) model

    Habib, S.; Mottola, E.; Tinyakov, P.

    1996-01-01

    Winding number transitions in the two-dimensional softly broken O(3) nonlinear σ model are studied at finite energy and temperature. New periodic instanton solutions which dominate the semiclassical transition amplitudes are found analytically at low energies, and numerically for all energies up to the sphaleron scale. The Euclidean period β of these finite energy instantons increases with energy, contrary to the behavior found in the Abelian Higgs model or simple one-dimensional systems. This results in a sharp crossover from instanton-dominated tunneling to sphaleron-dominated thermal activation at a certain critical temperature. Since this behavior is traceable to the soft breaking of conformal invariance by the mass term in the σ model, semiclassical winding number transition amplitudes in the electroweak theory in 3+1 dimensions should exhibit a similar sharp crossover. We argue that this is indeed the case in the standard model for M H W . copyright 1996 The American Physical Society

    Goals such as fairness, participation and social compatibility will play in the future an increasingly important role in the struggle to find the right solutions for the energy transition, be it in the reform of the allocation and remuneration system, the expansion of wind energy on land, the sector coupling or the heat and traffic turnaround. WWith the first ''Social sustainability barometer of the energy transition'', published in November 2017, the IASS presents a monitoring instrument with a comprehensive, empirically sustainable database on the social dimensions of energy turnaround: it records annually the attitudes, justice sensations, experiences and expectations of different population groups in Germany with regard to the energy transition and identifies social challenges and political needs for action.

    The perspectives of the depletion of fossil energy resources, together with the consequences of climate change, have provoked the development of numerous national and pluri-national energy policies. However, there have been few overall studies on the evolution of these resources. This paper uses a dynamic model to study the exhaustion patterns of world fossil and nuclear fuels and their possible replacement by renewable energy sources. The results show that peak oil will be the first restriction and it will not be easily overcome. Electric vehicles can produce some interesting savings, but they are insufficient to avoid the decline in oil. Biofuels are even more limited, due to the enormous extensions of fertile land they require and their low productivity. This shows that overcoming the decline in oil will need much more ambitious policies than the mere substitution of technology. If the “oil–economy” relationship does not change substantially, world economic growth may be seriously limited or even negative. In contrast, the production of electrical energy is not such a worrying problem in the short and middle-term. - Highlights: ► We study world energy demand and resources with a systems dynamics model. ► We find that peak oil cannot be overcomed with simple technological substitution. ► Past economic growth and energy intensity trends cannot be maintained. ► Electric vehicles are only a partial solution, biofuels are even more limited. ► Substitution of electric energy by renewables is much easier than oil substitution.

  2. Treatment of Electronic Energy Level Transition and Ionization Following the Particle-Based Chemistry Model

    2010-01-01

    A new method of treating electronic energy level transitions as well as linking ionization to electronic energy levels is proposed following the particle-based chemistry model of Bird. Although the use of electronic energy levels and ionization reactions in DSMC are not new ideas, the current method of selecting what level to transition to, how to reproduce transition rates, and the linking of the electronic energy levels to ionization are, to the author s knowledge, novel concepts. The resulting equilibrium temperatures are shown to remain constant, and the electronic energy level distributions are shown to reproduce the Boltzmann distribution. The electronic energy level transition rates and ionization rates due to electron impacts are shown to reproduce theoretical and measured rates. The rates due to heavy particle impacts, while not as favorable as the electron impact rates, compare favorably to values from the literature. Thus, these new extensions to the particle-based chemistry model of Bird provide an accurate method for predicting electronic energy level transition and ionization rates in gases.

  3. Making the transition to middle schooling: A case study of experienced science teachers coping with change

    Science.gov (United States)

    Strong, Donna Dorough

    The increasing popularity of the middle school movement necessitates a need for more interpretive research in middle level education. The purpose of this qualitative case study was to explore science teachers' perceptions of the transition to a new middle school and the meanings they attached to this new experience. The participants were three eighth grade science teachers, each with 20 plus years of teaching experience. The primary data for analysis was a series of five interviews with each participant. Data collection also included weekly participant observation of team meetings. Findings revealed that the science teachers all had positive feelings attached to the ability to keep track of students' academic progress and behavior problems as a result of teaming. The changes associated with the first year were very stressful for all three, primarily the loss of the traditional junior high departmentalized structure. The two participants who transferred directly from the junior high school were very skeptical of any benefits from an interdisciplinary curriculum, the appropriateness of the middle school philosophy for eighth grade students, and the move to heterogeneously grouped science classes. In contrast, the former junior high teacher who had spent the past ten years teaching sixth grade at the elementary school had positive beliefs about the potential benefits of an interdisciplinary curriculum and heterogeneous grouping. Teacher stress associated with a change in the school setting and the science teachers' constraints to actualizing a meaningful middle schooling experience are illuminated. Teachers' lack of ownership in the reform decision making process, loss of time with their science teacher peers, diminished compliments from high school counterparts, and need for more empirical evidence supporting proposed changes all served as barriers to embracing the reform initiatives. The participants found taking a very slow approach to be their most useful means of

    2017-10-01

    This Policy Brief sets out six priorities to accelerate the energy transition in France based on learning from recent or ongoing studies at IDDRI: initiating large-scale energy efficiency retrofitting; anticipating and planning the transformation of the electricity system; shaping the transformation in the mobility sector through green objectives; integrating local energy management methods; mobilizing funding sources for the energy transition; placing the energy transition at the heart of the European and global agenda. Recommendations: A review of sectoral policies is necessary to set the country on track to achieving national energy policy objectives: overhauling incentive mechanisms to encourage large-scale energy efficiency retrofitting, smoothing the road for new renewable energy projects while outlining a clear strategy for a reduction of the installed capacity of nuclear, identifying and using levers addressing mobility needs within land use policy measures. A plan to tackle mobility-related vulnerability with a dedicated mechanism to support employees and regions vulnerable to economic restructuring due to the closing of industrial sites will help ensure a 'just' and inclusive transition. New modes of energy governance and interaction between local authorities and citizens could also be promoted so that they can become real tools for the facilitation of the transition at a regional and local level. In addition to the already-announced environmental fiscal reforms, some thought on the distribution channels for financial flows and their modalities would help in mobilizing the necessary funds and reinforcing the attractiveness of these mechanisms and the effectiveness of the public funds committed. The proposal for an Energy Union could play a major part in boosting the European Union and placing it at the forefront of strengthening ambition during international negotiations on climate.

    We compare two different ways of quantum modification in a simple sequential game called Cat's Dilemma in the context of the debate on intransitive and transitive preferences. This kind of analysis can have essential meaning for research on artificial intelligence (some possibilities are discussed). Nature has both transitive and intransitive properties and perhaps quantum models will be more able to capture this dualism than the classical models. We also present an electoral interpretation of the game.

    The geopolitical analyses of energy markets are traditionally focused on fossil fuels, and less on renewable energy sources. Yet the huge development perspectives of these renewable energy sources (representing 2/3 of total net power generation capacity additions in 2016) trigger a need to take into account new challenges and vulnerabilities, related to the availability and affordability of critical raw materials, notably rare earths, which are needed to develop wind turbines, solar panels and energy storage technologies. Stakes are geopolitical, economic and environmental and are reinforced by a geography of resources and production which is concentrated within a few key countries and zones (China, Latin America, Australia, Congo mainly). The role of China in particular is at the core of the attention

    Full Text Available In recent years, many cities have adopted action plans to become climate neutral in the coming decades. Hereby, a strong motivational factor has been the goal to realize a win-win situation in the long term: climate neutrality and sustainable functioning are not only beneficial for the environment, but are equally beneficial for society and for the economy if well-integrated trajectories are adopted. Nevertheless, as actors across the fields start to implement these plans, many practical obstacles have arisen. These barriers are typical of a systemic transition: dominant practices are characterized by path dependencies, vast institutional frameworks and vested interests that are hard to break through. At the same time, relevant initiatives typically show some elements of uncertainty and a long term return, factors that make it difficult to attract financial investments. The present article addresses the state of the art for current transition experiments in the region of Flanders, Belgium, focusing on actions related to energy and buildings in cities. A brief overview of the state of affairs in several cities and provinces is presented, and some important opportunities and bottlenecks are identified. The resultant findings are tested against the framework of transition theory and related literature on the subject. Subsequently, a set of possible strategies to overcome the above mentioned barriers is formulated. These strategies focus on effectively mobilizing actors and investments.

    In a first article, the author discusses the possible content of a law on energy transition which is supposed to be voted by the Parliament during the autumn 2014, and which will probably decide the shutting down of some French nuclear plants. The author outlines the social, economical and energy-related consequences of such a policy. In a second article he rejoices over the publication of two reports (one on the Energy Climate Package by the Cour des Comptes, and one by the General Commissioner for Strategy and Prospective) which consider that the objectives of development of renewable energies (notably wind and photovoltaic) are too ambitious and even unrealistic, and outline the bad management of investments and the inefficiency of action by the ADEME and the Ministry of Ecology. In the third article he denounces fifteen 'tales' about the German energy model, the uselessness of seven German nuclear plants which have been stopped, the low cost of energy transition, the environmental benefit of renewable energies, the high potential of energy savings, the new electricity storage means, the electric car as a new mean of storage of electric current, the sun which does not send any bill, wind energy (when a wind farm is said to be able to supply energy to so many thousands households), geothermal energy production, technological leap, the benefit of decentralization, the miracle of job creation by renewable energies, the ecologic electricity, nuclear wastes we do not know what to do with

    With the energy transition, the Federal Government has begun the conversion of the energy supply. Because of the success of the energy transition is essential for the future and competitiveness of Germany as a business location The Federal Association of German Industry (BDI) has already published 2013 Stimulus for a smart energy market, in which are derived five principles which provide a framework for discourse on the measures to be taken. Renewable energies will be the dominant source of electricity in the coming years. This results in new challenges. The Federal Ministry of Economics and Technology (BMWi) has recently adopted a 10-point agenda to address these issues (ZPA) for the central energy projects. To be discussed is to what extent they are in harmony with the five principles of the BDI and at which points adjustments are necessary, so that the conversion of the energy system can succeed. [de

    Last May the International Energy Agency (IEA) published an analysis of the energy transition in Germany. This analysis acknowledges the efforts made by Germany for a better energy efficiency and for the important development of renewable energies but also highlights 3 concerns. First, the cost for the energy transition is not fairly dispatched: electrical power is far more expensive for households than for enterprises. Secondly, according to the IEA, measures must be taken to restrain the growing costs of renewable energies and to foster investment to develop smart grids. Thirdly, the IEA misses the lack of coordination of Germany's energy policy with foreign countries' ones as German decisions have an impact beyond its frontiers. (A.C.)

    Full Text Available Facing heavy air pollution, China needs to transition to a clean and sustainable energy system, especially in the power and transport sectors, which contribute the highest greenhouse gas (GHG emissions. The core of an energy transition is energy substitution and energy technology improvement. In this paper, we forecast the levelized cost of electricity (LCOE for power generation in 2030 in China. Cost-emission effectiveness of the substitution between new energy vehicles and conventional vehicles is also calculated in this study. The results indicate that solar photovoltaic (PV and wind power will be cost comparative in the future. New energy vehicles are more expensive than conventional vehicles due to their higher manufacturer suggested retail price (MSRP. The cost-emission effectiveness of the substitution between new energy vehicles and conventional vehicles would be $96.7/ton or $114.8/ton. Gasoline prices, taxes, and vehicle insurance will be good directions for policy implementation after the ending of subsidies.

    Energy Technology Data Exchange (ETDEWEB)

    Lancaster, T.D.

    1983-01-01

    This dissertation examines the effects of peaceful regime change on public policy-making. Spain's National Energy Plan (PEN) in particular, and energy planning in general, constitute a critical policy issue which permits direct comparison of decision-making across regime change from the Franco dictatorship to the present constitutional monarchy. The research reveals that the nature of the political coalition underlying Spain's regime change accounts of the lack of significant change in policy-making processes in this particular policy issue. This thesis develops a two-pronged argument to explain the absence of significant policy change. The first is based on a general view of the Franco regime's and the democratic system's coalitional support. In each, three major political forces are seen as central: the military, business, and labor. One of these, business, is seen as being pivotal in the regime transition. Business' pivotal position, it is argued, has permitted a defence of a national energy policy beneficial to its economic interests in energy. The argument's second part focuses on the binding constraint on policy outcomes imposed by private interests in state planning and the generally non-binding nature of oppositional party policy proposals and public opinion.

    2009-01-01

    'Full text:' This presentation will address climate change and transition to a lower carbon economy in general and the importance of sustainable energy in such initiatives. The talk has two main parts. In the first part, the presenter discuss why non-fossil fuel energy options, which are diverse and range from renewables through to nuclear energy, are needed to help humanity combat climate change and transition to a lower carbon economy. Such energy options reduce or eliminate emissions of greenhouse gases and thus often form the basis of sustainable energy solutions. Nonetheless, carbon dioxide capture and sequestration may allow fossil fuels to be less carbon emitting. Sustainable energy options are not sufficient for avoiding climate change, in that they are not necessarily readily utilizable in their natural forms. Hydrogen energy systems are needed to facilitate the use of non-fossil fuels by allowing them to be converted to two main classes of energy carriers: hydrogen and select hydrogen-derived fuels and electricity. As hydrogen is not an energy resource, but rather is an energy carrier that must be produced, it complements non-fossil energy sources, which often need to be converted into more convenient forms. In addition, high efficiency is needed to allow the greatest benefits to be attained from all energy options, including non-fossil fuel ones, in terms of climate change and other factors. Efficiency improvements efforts have many dimensions, including energy conservation, improved energy management, fuel substitution, better matching of energy carriers and energy demands, and more efficiency utilization of both energy quantity and quality. The latter two concepts are best considered via the use of exergy analysis, an advanced thermodynamic tool. In the second part of the presentation, actions to address climate change more generally and to help society transition to a lower carbon economy are described. The role of sustainable energy in this

    2016-01-01

    Recognized as implementation actors of operative measures for transition towards a low carbon economy, cities must establish a development roadmap integrating local resources with local energy development plans. A systematic approach does not exist yet and cities develop their plans individually, which is difficult for small and medium sized cities due to limited development capacities. Conventional city planning approaches do not integrate considerations on energy, economy and environment in transition plans in an easily comparable way, yet making decisions with regards to these parameters is vital to determine outcomes of planned developments on future sustainability of the city. The paper presents a framework model based on emergy synthesis which integrates energy, economic and environmental city systems in the decision making process, examining associated theoretical challenges and application limitations. The method is applied on the city of Sisak in Croatia which has developed plans to implement several initiatives geared towards creating a smart energy city. The model enables simulation and assessment of impacts of individual projects targeting the development of a smart energy city on city sustainability expressed through emergy performance, used as a tool for evaluating local development alternatives within the boundary of local resources. - Highlights: • Key concepts of present city development trends towards sustainability are examined. • Emergy synthesis is examined and applied as a tool for policy and decision makers. • Emergy model of a small city is developed, along with submodels for renewable energy sources and buildings. • Simulation of 5 different projects shows impacts on overall city sustainability in a comparable manner. • Increase in emergy sustainability index is confirmed after presumed implementation of simulated projects.

    The aim of this research paper is to investigate factors and mechanisms that may facilitate the transition from coal resource-based economy to sustainability. Based on the energy technology innovation theory, factors that may influence the transition of coal resource-based economy were categorized into four types, including: innovation policy, innovation input, innovation ability, and innovation organization. Hypotheses were proposed regarding the mechanisms of these factors. Data were collected from surveys administered to 314 Chinese energy firms, and a structural equation model (SEM) was employed to test the hypotheses. Ten of fifteen hypotheses were retained based on the reliability tests, validity tests, and SEM. The results show that the four proposed factors are crucial in transforming the coal resource-based economy, and the effects become statistically significant through three intermediate variables, namely, transition of energy consumption structure, correction of resource wealth investment, and improvement of transition environment. - Highlights: •Approximately, 66% of energy relies on coal in China. •Serious environment problems have occurred in many coal-based regions. •Energy technology innovation can promote the transition of coal-based economy. •China should accelerate the development of clean energy.

  20. Study of the coefficients of internal conversion for transition energies approaching the threshold

    Internal conversion coefficients were determined experimentally with great accuracy for areas of transition energies, which constitute tests for the theories (energies at the most ten kEv above the threshold of K shell), then the results obtained were compared with the values calculated (or to be calculated) from theoretical models. Owing to the difficulties raised by the precise determination of the internal conversion coefficients (ICC), in the first stage we selected radionuclides with a relatively simple decay pattern, the transitions: 30 keV of sup(93m)Nb, 35 keV of sup(125m)Te, 14 keV of 57 Fe and 39 keV of sup(129m)Xe. It was observed that 'problems' exist with respect to the ICC's of the great multipolarity transitions, so the transitions of this kind were examined in a systematic manner. The possibility of penetration effects occurring for the transitions studied experimentally was examined. The considerations are presented which 'authorized' us to disregard the dynamic part of the ICC for the transitions approaching the threshold (L selection rules and life of nuclear levels in relation to Weisskopf-Moszkowski estimations). The Kurie straight line was determined experimentally for the β - transition and the Qsub(β) was evaluated with an important accuracy gain compared with the values available at present. Finally, a certain number of ICC's of transitions already determined with good precision were recalculated, in order to extend our analysis and detect any possible systematic errors [fr

  2. Resilience Thinking as an Interdisciplinary Guiding Principle for Energy System Transitions

    2016-09-01

    Full Text Available Resource usage and environmental consequences of most current energy systems exceed planetary boundaries. The transition to sustainable energy systems is accompanied by a multitude of research methods, as energy systems are complex structures of technical, economical, social and ecological interactions. The description of different discipline’s perspectives in this paper show that a more mutual understanding between disciplines of their respective focus is necessary as they partly create internally competitive views arising from differing emphasis of connected matters. The purpose of this paper is to present a framework for interdisciplinary proceeding in a complex energy system transition process. Resilience thinking is chosen as a core concept for a more holistic view on sustainable energy system development. It is shown that it is already widely used in different disciplines connected to energy system research and is especially suitable due to its wide application across disciplines. The seven principles of resilience thinking (maintain redundancy and diversity, manage connectivity, manage slow variables and feedback, foster complex adaptive systems thinking, encourage learning, broaden participation, and promote polycentric governance systems are chosen as the basis for a procedure that can be utilized to increase the interdisciplinary perspectives of energy system transitions. For energy transition processes based on scenario development, backcasting and pathway definition, resilience thinking principles are used to assess the resilience of the target energy system, the pathway resilience and the design of the scenario process with respect to the probability of a resilient outcome. The described procedure consisting of questions and parameters can be applied as a first attempt for a resilience assessment of energy transition processes. The perspective of resilience in sustainable energy systems strengthens the importance of diversity

  3. The stuttering energy transition in Germany: Wind energy policy and feed-in tariff lock-in

    2015-01-01

    This article aims to examine whether the formulation of specific low carbon policy such as the feed-in tariff for wind energy in Germany can partly be a barrier to a comprehensive energy transition (Energiewende). Despite their short and medium-term success, these policies could create a long-term lock-in if they are formulated in a way that leads to a stagnation of systems innovation. The research finds that while the share of wind energy has increased rapidly over time, the feed-in-tariff and other low carbon policies and incentives have not been sufficient to achieve a socio-technical regime transition in Germany yet. We suggest that the German feed-in-tariff has incorporated wind energy (a niche-innovation) and wind energy actors (pathway newcomers) into a slightly modified socio-technical regime that is rather similar to the earlier ‘fossil fuel dominant’ socio-technical regime. -- Highlights: •Feed-in tariff favours specific wind innovation, rather than energy transition. •Wind energy incorporated into a slightly modified socio-technical regime. •The outdated grid infrastructure is a bottleneck for the wind energy sector

    Operational flexibility in electrical energy generation and consumption as well as the provision of reliable and available capacity are two major challenges of the German energy transition ('Energiewende'). The consistent deployment of cost-effective and proven pumped storage technology can provide significant contributions to meet both challenges. This paper shows that an expansion of pumped storage plants as part of the energy transition is a technically and macro-economically interesting option for Germany. Pumped storage plants compensate the volatility of renewables and enable gentle and economically efficient operation of the remaining thermal power plant fleet.

  6. Mass- and energy-dependence of (π+,π-) double isobaric analog transitions at low energies

    Transitions to double isobaric analog states (DIAT) have been measured in the double charge exchange (DCX) reaction (π + ,π - ) for the nuclei 26 Mg, 56 Fe at Tsub(π+) = 49 MeV and for 18 O at Tsub(π+) = 24 MeV, 33 MeV, 49 MeV, 64 MeV and 79 MeV for several angles. The experiments have been performed at the pion channels M13 and M11 of TRIUMF using the low energy pion spectrometer QQD. The forward angle cross sections for 18 O can be understood in a quark model as well as in conventional models where the reaction is mainly proceeding through intermediate deltas or low lying excited states of the intermediate nucleus. The angular distribution of 26 Mg at 49 MeV is found to be almost identical to those of 14 C and 18 O while the cross section remarkedly drops for 56 Fe. The forward angle excitation function of 18 O exhibits a maximum at around 35 MeV. The present results are compared to theoretical predictions. Two approaches for a unified study of SCX and DCX at energies ranging from 20 MeV up to 300 MeV are presented. The first is carried out in a mean free path model for investigations of geometry effects in the reaction. For the second, the optical model code PIESDEX is employed. Both studies indicate that the observed mass dependence for DCX at 50 MeV can be explained partly by geometry considerations and partly by details in the nuclear matter distributions of core neutrons and valence neutrons. Furthermore, the optical model investigation reveals the need of shifting the free πN-SCX amplitude down by 30 MeV in order to achieve good agreement with experimental data. (orig.)

    2014-01-01

    The many lively debates that preceded -and still fuel- discussion of the 'Energy Transition and Green Growth' bill attest to the importance of that law for many French citizens and economic actors. Without going back over the debate on the feasibility or realism of the law's objectives, to which Futuribles contributed through its web site in late September, it is possible to put these matters into some perspective, as Patrick Criqui does here, by reminding us of the genealogy of the bill and the various future scenarios that were developed during the French National Debate on Energy Transition of 2013 before the bill passed into law. Criqui reminds us of the possible scenarios discussed, grouped as they were around four major energy trajectories: 'Energy-saving', 'Efficiency', 'Diversity' and 'Decarbonization'. Among these, the most important sources of divergence were over the level of reduction of energy consumption by 2050 and the relative parts to be played by nuclear power and renewable energies. Basing himself on the target figures included in the bill, Patrick Criqui identifies the image of the future towards which, on the face of it, the law points -namely, the 'Efficiency' trajectory- even if, as he very rightly emphasizes, its implementation will definitely be a dynamic affair, incorporating the various adaptations that might turn out to be necessary between now and 2050.

  9. Modeling and control of distributed energy systems during transition between grid connected and standalone modes

    Science.gov (United States)

    Arafat, Md Nayeem

    Distributed generation systems (DGs) have been penetrating into our energy networks with the advancement in the renewable energy sources and energy storage elements. These systems can operate in synchronism with the utility grid referred to as the grid connected (GC) mode of operation, or work independently, referred to as the standalone (SA) mode of operation. There is a need to ensure continuous power flow during transition between GC and SA modes, referred to as the transition mode, in operating DGs. In this dissertation, efficient and effective transition control algorithms are developed for DGs operating either independently or collectively with other units. Three techniques are proposed in this dissertation to manage the proper transition operations. In the first technique, a new control algorithm is proposed for an independent DG which can operate in SA and GC modes. The proposed transition control algorithm ensures low total harmonic distortion (THD) and less voltage fluctuation during mode transitions compared to the other techniques. In the second technique, a transition control is suggested for a collective of DGs operating in a microgrid system architecture to improve the reliability of the system, reduce the cost, and provide better performance. In this technique, one of the DGs in a microgrid system, referred to as a dispatch unit , takes the additional responsibility of mode transitioning to ensure smooth transition and supply/demand balance in the microgrid. In the third technique, an alternative transition technique is proposed through hybridizing the current and droop controllers. The proposed hybrid transition control technique has higher reliability compared to the dispatch unit concept. During the GC mode, the proposed hybrid controller uses current control. During the SA mode, the hybrid controller uses droop control. During the transition mode, both of the controllers participate in formulating the inverter output voltage but with different

    The Energy Transition (''Energiewende'') is one of the hot topics of the political debate in Germany for some years. As a consequence of ongoing European integration, EU level politics have gained growing importance. The focus of this study is on the interaction of German and EU energy and climate policies. How have German actors influenced EU policy-making processes and in how far are EU policies relevant for national policy-making in Germany? Three case studies look at processes in the fields of electricity market regulation, renewable energy policy and climate protection between 2007 and 2013.

  11. Energy barrier of bcc-fcc phase transition via the Bain path in Yukawa system

    2018-05-01

    In the Yukawa system with the dimensionless screening parameter κ>1.5 , when bcc-fcc transition occurs via Bain path, we show that spontaneous transitions do not occur even if the system temperature reaches the transition point of bcc-fcc because it is necessary to increase once the free energy in the process of transition from bcc to fcc through Bain deformation. Here, we refer the temporary increment of the free energy during Bain deformation as Bain barrier. Since there are the Bain barriers at the transitions between bcc and fcc phases, these phases may coexist as metastable state in the wide region (not a coexistence line) of κ and the coupling constant Γ. We study the excess energy of the system and the free energy difference between bcc and fcc phases by the Monte Carlo method, where the simulation box is divided into a large number of elements with small volume and a particle in the box is restricted be placed in one of these elements. By this method, we can tabulate the values of the interparticle potential and can calculate the internal energy fast and precisely.

  12. The demand for environmental quality in driving transitions to low-polluting energy sources

    2012-01-01

    The purpose of this paper is to understand the long run demand for energy-related environmental quality, its influence on legislation and on transitions to low polluting energy sources. It presents a series of episodes in British history where a demand for improvements in energy-related environmental quality existed. These episodes helped to identify a few cases where markets partially drove transitions to low polluting energy sources, in specific economic conditions. More generally, they showed that, when pushed, governments will introduce environmental legislation, although it tends to be weak and poorly enforced. In the case of air pollution, strong and binding legislation occurred roughly one hundred years later than was socially optimal. Based on this evidence, for a transition to a low carbon economy, governments will probably need to introduce focussed and binding legislation, and this cannot be expected without strong and sustained demand for climate stability. This demand will need to be spearheaded by pressure groups to introduce legislation, to enforce it and to avoid it being over-turned by future governments. - Highlights: ► Reviews demand for improvements in environmental quality in British history. ► In special cases, demand may drive transitions through markets. ► Demand will probably have to drive transitions to low polluting energy through legislation. ► Need for strong and sustained demand spearheaded through pressure groups.

  14. Characterizing structural transitions using localized free energy landscape analysis.

    Directory of Open Access Journals (Sweden)

    Nilesh K Banavali

    Full Text Available Structural changes in molecules are frequently observed during biological processes like replication, transcription and translation. These structural changes can usually be traced to specific distortions in the backbones of the macromolecules involved. Quantitative energetic characterization of such distortions can greatly advance the atomic-level understanding of the dynamic character of these biological processes.Molecular dynamics simulations combined with a variation of the Weighted Histogram Analysis Method for potential of mean force determination are applied to characterize localized structural changes for the test case of cytosine (underlined base flipping in a GTCAGCGCATGG DNA duplex. Free energy landscapes for backbone torsion and sugar pucker degrees of freedom in the DNA are used to understand their behavior in response to the base flipping perturbation. By simplifying the base flipping structural change into a two-state model, a free energy difference of upto 14 kcal/mol can be attributed to the flipped state relative to the stacked Watson-Crick base paired state. This two-state classification allows precise evaluation of the effect of base flipping on local backbone degrees of freedom.The calculated free energy landscapes of individual backbone and sugar degrees of freedom expectedly show the greatest change in the vicinity of the flipping base itself, but specific delocalized effects can be discerned upto four nucleotide positions away in both 5' and 3' directions. Free energy landscape analysis thus provides a quantitative method to pinpoint the determinants of structural change on the atomic scale and also delineate the extent of propagation of the perturbation along the molecule. In addition to nucleic acids, this methodology is anticipated to be useful for studying conformational changes in all macromolecules, including carbohydrates, lipids, and proteins.

  17. Deregulation - precondition for distributed energy in the economies in transition

    International Nuclear Information System (INIS)

    Brendow, K.

    2001-01-01

    This paper holds that deregulation, i.e. restructuring, competition and privatisation, is the main precondition for a more pronounced development of distributed power (DP) in the economies in transition in central and eastern Europe. This, then, raises the question how far the electricity, gas, steam and heat generating industries have presently moved on their way towards more market-oriented frameworks, competition and private ownership. A good benchmark for measuring progress is the existence (or lack thereof), and nature, of regulatory regimes enabling fair competition among large centralised and small decentralised power, and between wholesale generators and distributors on the one hand and customers or ''autoproducers'' or power merchants on the other. The paper describes the regulatory models applied or contemplated in the winter 2000/2001 in the various countries of central and eastern Europe and identifies fifteen general issues that require attention and solution. With regard to DP, it concludes that a major upswing is unlikely to occur before 2005-2008. While technological options abound, the institutional frameworks for customer-owned competitive DP systems are only being contemplated at present and only rarely put in place.(author)

    Full Text Available The duality between E8xE8 heteritic string on manifold K3xT2 and Type IIA string compactified on a Calabi-Yau manifold induces a correspondence between vector bundles on K3xT2 and Calabi-Yau manifolds. Vector bundles over compact base space K3xT2 form the set of isomorphism classes, which is a semi-ring under the operation of Whitney sum and tensor product. The construction of semi-ring V ect X of isomorphism classes of complex vector bundles over X leads to the ring KX = K(V ect X, called Grothendieck group. As K3 has no isometries and no non-trivial one-cycles, so vector bundle winding modes arise from the T2 compactification. Since we have focused on supergravity in d = 11, there exist solutions in d = 10 for which space-time is Minkowski space and extra dimensions are K3xT2. The complete set of soliton solutions of supergravity theory is characterized by RR charges, identified by K-theory. Toric presentation of Calabi-Yau through Batyrev's toric approximation enables us to connect transitions between Calabi-Yau manifolds, classified by enhanced symmetry group, with K-theory classification.

    This is an extension of the Suzuki model (base model) on optimal transition from resource-limited energy (oil) to advanced energy with virtually unlimited resource. The finite length of plant life, fuel cost, technological progress factor of advanced energy and the upper limit upon annual consumption rate of oil are taken into account for such an extension. The difference in optimal solutions obtained from extended and base models is shown by an application of the maximum principle. The implication of advanced energy R and D andenergy conservation effort is also discussed. (author)
