    Pakistan is beset with serious energy supply difficulties arising from a fast growing demand for commercial energy, a poor energy resource base and the high cost of imported energy. The commercial energy requirements are expected to rise from 22.4 million tonnes of coal equivalent (tce) in 1980 to 80 million tce by the year 2000 and to about 200 million tce by 2020, while the country's proven fossil-fuel reserves are only 440 million tce and cannot cope with the demand for long. Pakistan is already dependent on imported energy for 90% of its oil requirements or 30% of the total commercial energy, and is spending 5.5% of its gross domestic product (GDP) on energy imports. The paper analyses the economic implications of a few alternative energy supply strategies. These strategies correspond to two different rates of petroleum exploration and development activity, a high and a low average size of new petroleum finds, and the large-scale use of nuclear power starting in 1990 or after the year 2000. It is found that in the most favourable case (high level of petroleum drilling activity with a high success rate and nuclear power use starting in 1990) Pakistan would be able to achieve self-sufficiency in oil by 2010 and in the total energy supply shortly after 2020. The energy sector's investment requirement will, however, increase gradually from 3% of GDP now to almost 6% of GDP by 2020. (author)

    In this study, we explored the effects of different design strategies on final and primary energy use for production and operation of a newly constructed apartment building. We analysed alternatives of the building “As built” as well as to energy efficiency levels of the Swedish building code and passive house criteria. Our approach is based on achieving improved versions of the building alternatives from combination of design strategies giving the lowest space heating and cooling demand and primary energy use, respectively. We found that the combination of design strategies resulting in the improved building alternatives varies depending on the approach. The improved building alternatives gave up to 19–34% reduction in operation primary energy use compared to the initial alternatives. The share of production primary energy use of the improved building alternatives was 39–54% of the total primary energy use for production, space heating, space cooling and ventilation over 50-year lifespan, compared to 31–42% for the initial alternatives. This study emphasises the importance of incorporating appropriate design strategies to reduce primary energy use for building operation and suggests that combining such strategies with careful choice of building frame materials could result in significant primary energy savings in the built environment. - Highlights: • Primary energy implications of different design strategies were analysed. • The improved building alternatives had 19–34% lower operation primary energy use. • The improved building alternatives had higher production primary energy use. • Still, the improved building alternatives had lower overall primary energy use. • Design strategies should be combined with careful building frame material choice.

    The long-term forecasting of energy supply and demand is of prime importance in Africa due to the steady increase in energy requirements, the non-availability of sufficient resources, the high dependence on fossil-fuels to meet these requirements, and the global concerns over the energy-induced environmental issues. This paper is concerned with modelling possible future paths for Africa's energy future and the related emissions. Future energy demand is forecasted based on socio-economic variables such as gross domestic product, income per capita, population, and urbanisation. The Long-range Energy Alternative Planning System (LEAP) modelling framework is employed to analyse and project energy demand and the related emissions under alternative strategies for the period of 2010–2040. Results of scenarios including business-as-usual (BAU) policies, moderate energy access and accelerate energy access policies, renewable energies promotion and energy efficiency policies and their environmental implications are provided. The study provides some policy insights and identifies synergies and trade-offs relating to the potential for energy policies to promote universal energy access, enable a transition to renewable energy, and mitigate climate change for a sustainable development. - Highlights: • Possible future paths for Africa's energy future and the related emissions are modelled. • Scenarios using an adaptation of Schwartz's scenario approach, under LEAP are developed. • Under the current energy policies, the universal access to modern energy will not be met by 2030. • Policies to accelerate the changes in energy structure are required for sustainable development. • Investing in Energy efficient strategies has emerged as one of the best solution.

    Cars, trucks, and other vehicles have long been linked to smog and other urban pollution, but the part they play in the larger complex of atmospheric and energy ills that we now face is often overlooked. In Driving Forces: Motor Vehicle Trends and Their Implications for Global Warming, Energy Strategies, and Transportation Planning, James J. MacKenzie, senior associate in World Resources Institute's Program in Climate, Energy, and Pollution, and Michael P. Walsh, an international consultant on transportation and environmental issues, fill in this knowledge gap with new data and analyses. They spell out four policy shifts that can help hold the line on global warming: improve new-vehicle efficiency; make transportation more efficient; cut other greenhouse gas emissions; create the green car of the future. The report focuses especially on the US, which pioneered the automotive revolution and leads the world in oil imports and emissions

    Wildlife planning for renewable energy must cope with the uncertainties of potential wildlife impacts. Unfortunately, the environmental policies which instigate renewable energy and those which protect wildlife are not coherently aligned—creating a green versus green dilemma. Thus, climate mitigation efforts trigger renewable energy development, but then face substantial barriers from biodiversity protection instruments and practices. This article briefly reviews wind energy and wildlife interactions, highlighting the lively debated effects on bats. Today, planning and siting of renewable energy are guided by the precautionary principle in an attempt to carefully address wildlife challenges. However, this planning attitude creates limitations as it struggles to negotiate the aforementioned green versus green dilemma. More adaptive planning and management strategies and practices hold the potential to reconcile these discrepancies to some degree. This adaptive approach is discussed using facets of case studies from policy, planning, siting, and operational stages of wind energy in Germany and the United States, with one case showing adaptive planning in action for solar energy as well. This article attempts to highlight the benefits of more adaptive approaches as well as the possible shortcomings, such as reduced planning security for renewable energy developers. In conclusion, these studies show that adaptive planning and operation strategies can be designed to supplement and enhance the precautionary principle in wildlife planning for green energy.

    The energy problem is set out as it appears to an economist. The paper then explains the nature of the strategic arguments, differentiating particularly between options that might be available to the world as a whole and options that are available to the UK as such. It is concluded that in UK there are no options: that all possible sources of energy should be developed, and all opportunities taken for conservation, subject to broad economic considerations. Government policies and sociological aspects are discussed. (U.K.)

  8. The Bush/Cheney Energy Strategy: Implications for U.S. Foreign and Military Policy

    The 'National Energy Policy' (NEP) released by the Bush Administration on May 17, 2001 was supposedly intended to meet growing U.S. energy requirements in the first two decades of the 21st Century while also diminishing U.S. dependence on imported oil. This was to be accomplished, the White House suggested, by increasing production at existing oil fields in the United States and by commencing drilling on the Artic National Wildlife Refuge (ANWR) in Alaska. So great was the furor over drilling on ANWR that most people never bothered to examine the NEP closely. This is unfortunate, as a close reading of the NEP report reveals a very different picture than that suggested by White House pronouncements: far from promoting energy 'independence', the NEP assumes that the United States will become MORE, not less dependent on imported petroleum in the years ahead and therefore calls on the Federal Government to take whatever steps are necessary to promote enhanced U.S. access to foreign oil. In particular, the NEP calls on the U.S. Government to seek additional petroleum from the Persian Gulf area, Russia, the Caspian Sea basin, Mexico, Venezuela, Angola, and Nigeria. As is implied by the report, the United States must acquire more oil from these countries in order to permit increased oil consumption in the United States at a time of declining domestic production. Even leaving aside the question of whether these countries will be able to boost their production sufficiently to satisfy steadily rising demand in the United States, this strategy poses enormous challenges for the United States because most of these areas are highly unstable and house anti-American governments and forces. It is likely, then, that U.S. efforts to acquire more oil from these countries will entail the increased presence of U.S. military forces in the area and periodic U.S. military intervention. Indeed, the requirement for increased military action in support of U.S. foreign

    The fluid-milk processing industry around the world processes approximately 60% of total raw milk production to create diverse fresh fluid-milk products. This paper reviews energy usage in existing global fluid-milk markets to identify baseline information that allows comparisons of energy performance of individual plants and systems. In this paper, we analyzed energy data compiled through extensive literature reviews on fluid-milk processing across a number of countries and regions. The study has found that the average final energy intensity of individual plants exhibited significant large variations, ranging from 0.2 to 12.6 MJ per kg fluid-milk product across various plants in different countries and regions. In addition, it is observed that while the majority of larger plants tended to exhibit higher energy efficiency, some exceptions existed for smaller plants with higher efficiency. These significant differences have indicated large potential energy-savings opportunities in the sector across many countries. Furthermore, this paper illustrates a positive correlation between implementing energy-monitoring programs and curbing the increasing trend in energy demand per equivalent fluid-milk product over time in the fluid-milk sector, and suggests that developing an energy-benchmarking framework, along with promulgating new policy options should be pursued for improving energy efficiency in global fluid-milk processing industry.

    Bangladesh is facing daunting energy challenges: Security concerns over growing fuel imports, limited domestic energy resources for power generation, and projected demands for electricity that will exceed domestic supply capabilities within a few years. By acknowledging the potential of renewable energy resources, the country could possibly meet its unprecedented energy demand, thus increasing electricity accessibility for all and enhancing energy security through their advancement. The integration of renewable energy technologies in the power sector through national energy planning would, therefore, be a step in the right direction, not only for sustainable development of the country but also as part of Bangladesh's responsibility toward the global common task of environmental protection. This study estimates the potential of renewable energy sources for power generation in Bangladesh from the viewpoint of different promising available technologies. Future long-term electricity demand in Bangladesh is projected based on three economic growth scenarios. The energy planning model LEAP is applied to forecast the energy requirements from 2005 to 2035. Different policy scenarios, e.g., accelerated renewable energy production, null coal import, CO2 emission reduction targets and carbon taxes in the power sector from 2005 to 2035 are explored. The analyses are based on a long-term energy system model of Bangladesh using the MARKAL model. Prospects for the power sector development of the country are identified, which ensure energy security and mitigate environmental impacts. The technical potential of grid-connected solar photovoltaic and wind energy are estimated at 50174 MW and 4614 MW, respectively. The potential of energy from biomass and small hydro power plants is estimated at 566 MW and 125 MW, respectively. Total electricity consumption was 18 TWh in 2005 and is projected to increase about 7 times to 132 TWh by 2035 in the low GDP growth scenario. In the

    The First National Energy Strategy, outlining the principal provisions of the Government on the reconstruction and development of energy sector, was approved for a comparatively long period - until the year 2015. The Energy Law envisages that the energy strategy is approved by the Parliament and has to be revised every five year. This National Energy Strategy amended and specified the energy development trends defined in 1994. The recent positive developments and tendencies in Lithuania's economy called for the necessity to revise the strategies for the further development of the infra structural areas, especially the energy sector. The preparation of an updated National Energy Strategy was based on the overall forecasts for the development of the country, and also experience, which was gained by participation in the programmes and studies supported by European Union and PHARE, and also priorities indicated in the National Programme for Adoption of Acquis (NPAA programme). Formulation of the basic goals of the National Energy Strategy included requirements of the European Association Agreement, Energy Charter, and also principles and tendencies in the energy sector development of the member countries

    This Comprehensive National Energy Strategy sets forth a set of five common sense goals for national energy policy: (1) improve the efficiency of the energy system, (2) ensure against energy disruptions, (3) promote energy production and use in ways that respect health and environmental values, (4) expand future energy choices, and (5) cooperate internationally on global issues. These goals are further elaborated by a series of objectives and strategies to illustrate how the goals will be achieved. Taken together, the goals, objectives, and strategies form a blueprint for the specific programs, projects, initiatives, investments, and other actions that will be developed and undertaken by the Federal Government, with significant emphasis on the importance of the scientific and technological advancements that will allow implementation of this Comprehensive National Energy Strategy. Moreover, the statutory requirement of regular submissions of national energy policy plans ensures that this framework can be modified to reflect evolving conditions, such as better knowledge of our surroundings, changes in energy markets, and advances in technology. This Strategy, then, should be thought of as a living document. Finally, this plan benefited from the comments and suggestions of numerous individuals and organizations, both inside and outside of government.

    The creation of a competitive energy market in Bulgaria is one of the top priorities in the government policy. To achieve this goal the following conditions are necessary: normalizing of the energy prices; financial healing; well working regulatory institutions and mechanisms; market rules and structures; appropriate legal framework. The main topics discussed in connection with the new energy strategy are: 1) General energy policy - competitive energetics; private investments and privatization; security of the energy supply, environment, energy efficiency; social protection and guarantees; 2) Sector policy - market regulation; licensing; effective use of the available power facilities; nuclear safety; 3) Gasification; 4) Heating; 5) Coal production. According to the strategy framework documents in the following aspects should be developed: integrated long-term plan 'Energetics-Environment'; price policy; market rules and structures; privatization strategies; healing programmes

    2012-09-04

    To understand the long-term energy and climate implications of different implementation strategies for carbon capture and storage (CCS) in the US coal-fired electricity fleet, we integrate three analytical elements: scenario projection of energy supply systems, temporally explicit life cycle modeling, and time-dependent calculation of radiative forcing. Assuming continued large-scale use of coal for electricity generation, we find that aggressive implementation of CCS could reduce cumulative greenhouse gas emissions (CO(2), CH(4), and N(2)O) from the US coal-fired power fleet through 2100 by 37-58%. Cumulative radiative forcing through 2100 would be reduced by only 24-46%, due to the front-loaded time profile of the emissions and the long atmospheric residence time of CO(2). The efficiency of energy conversion and carbon capture technologies strongly affects the amount of primary energy used but has little effect on greenhouse gas emissions or radiative forcing. Delaying implementation of CCS deployment significantly increases long-term radiative forcing. This study highlights the time-dynamic nature of potential climate benefits and energy costs of different CCS deployment pathways and identifies opportunities and constraints of successful CCS implementation.

    The International White Land association unites under its roof scientists,engineers, institutes and enterprises from different countries(Russia,the US, Japan, France,lndia,etc) The White Land association raised a question: is it possible on the basis of modem knowledge of physics and existing modern technologies to build a global energy system which would produce enough energy to satisfy all human needs and, at the same time, provide for a normal coexistence between humankind and Nature? Evaluation of the existing energy system from a holistic planetary perspective made it possible to formulate the following criteria for an energy system. Integrity. An energy system must be integral, i.e. include all stages of power generation and consumption, from production and transportation of fuel to production, transmission and utilization of power and elimination of waste, the latter including the energy system itself which becomes waste after the completion of its life cycle. Efficiency. Net of the amount of power produced, and of the power expended (on extraction of primary material, production, transportation and waste disposal), should be sufficient to satisfy all human energy needs. Safety. An energy system as a whole, and each of its components, should be inherently safe, i.e. no outside impact such as earthquake, explosion, flooding, fire, act of sabotage or human error could, by definition, ever cause unacceptable damage to the environment. Operating reliability. Reliability should be assured by a sufficiently straight forward procedure of interaction between the operator and the power production/consumption system, so that no inordinately high-level training should be required for the personnel. Guaranteed resources. The system should be provided with sufficient fuel and other resources for power production in. amounts necessary to satisfy all human energy needs for a long time to come. Recycling. Used fuel should be repeatedly returned into the energy cycle for

    As bottled water use continues to expand around the world, there is growing interest in the environmental, economical, and social implications of that use, including concerns about waste generation, proper use of groundwater, hydrologic effects on local surface and groundwater, economic costs, and more. A key concern is how much energy is required to produce and use bottled water. This paper estimates the energy footprint required for various phases of bottled water production, transportation, and use. We do not develop a single comprehensive life-cycle energy estimate because of differences among water sources, bottling processes, transportation costs, and other factors, but we quantify key energy inputs necessary for site-specific assessments. We also apply these inputs to three site-specific examples of the energy required from production to the point of use: local bottled water produced and used in Los Angeles, water bottled in the South Pacific and shipped by cargo ship to Los Angeles, and water bottled in France and shipped in various ways to Los Angeles. For water transported short distances, the energy requirements of bottled water are dominated by the energy used to produce the plastic bottles. Long-distance transport, however, can lead to energy costs comparable to, or even larger than, those of producing the bottle. All other energy costs-for processing, bottling, sealing, labeling, and refrigeration-are far smaller than those for the production of the bottle and transportation. These data can be used to generate specific estimates for different sources, treatments, and delivery options.

  4. Accounting for Human Health and Ecosystems Quality in Developing Sustainable Energy Products: The Implications of Wood Biomass-based Electricity Strategies to Climate Change Mitigation

    Science.gov (United States)

    Weldu, Yemane W.

    The prospect for transitions and transformations in the energy sector to mitigate climate change raises concerns that actions should not shift the impacts from one impact category to another, or from one sustainability domain to another. Although the development of renewables mostly results in low environmental impacts, energy strategies are complex and may result in the shifting of impacts. Strategies to climate change mitigation could have potentially large effects on human health and ecosystems. Exposure to air pollution claimed the lives of about seven million people worldwide in 2010, largely from the combustion of solid fuels. The degradation of ecosystem services is a significant barrier to achieving millennium development goals. This thesis quantifies the biomass resources potential for Alberta; presents a user-friendly and sector-specific framework for sustainability assessment; unlocks the information and policy barriers to biomass integration in energy strategy; introduces new perspectives to improve understanding of the life cycle human health and ecotoxicological effects of energy strategies; provides insight regarding the guiding measures that are required to ensure sustainable bioenergy production; validates the utility of the Environmental Life Cycle Cost framework for economic sustainability assessment; and provides policy-relevant societal cost estimates to demonstrate the importance of accounting for human health and ecosystem externalities in energy planning. Alberta is endowed with a wealth of forest and agricultural biomass resources, estimated at 458 PJ of energy. Biomass has the potential to avoid 11-15% of GHG emissions and substitute 14-17% of final energy demand by 2030. The drivers for integrating bioenergy sources into Alberta's energy strategy are economic diversification, technological innovation, and resource conservation policy objectives. Bioenergy pathways significantly improved both human health and ecosystem quality from coal

    This book provides the first comprehensive and integrated model of the UK energy sector which focuses on decision-making and optimisation rather than on forecasting or simulation. It incorporates the production and investment policy of all the major fuels (coal, oil, gas and electricity) over a fifty year horizon and analyses strategy under a variety of different assumptions about costs, demands, technolgy and future decisions. The authors cover the wide spectrum of energy problems and policy, including scenarios of rising il and gas prices, and there are striking calculations of the (low) costs of a non-nuclear plus conservation strategy.

    Full Text Available Many studies have been conducted to explore language learning strategies (Rubin, 1975, Naiman et . al ., 1978; Fillmore, 1979; O'Malley et . al ., 1985 and 1990; Politzer and Groarty, 1985; Prokop, 1989; Oxford, 1990; and Wenden, 1991. In the current study a total of 79 university students participating in a 3 month English course participated. This study attempted to explore what language learning strategies successful learners used and to what extent the strategies contributed to success in learning English in Indonesia . Factor analyses, accounting for 62.1 %, 56.0 %, 41.1 %, and 43.5 % of the varience of speaking, listening, reading and writing measures in the language learning strategy questionnaire, suggested that the questionnaire constituted three constructs. The three constructs were named metacognitive strategies, deep level cognitive and surface level cognitive strategies. Regression analyses, performed using scales based on these factors revealed significant main effects for the use of the language learning strategies in learning English, constituting 43 % of the varience in the posttest English achievement scores. An analysis of varience of the gain scores of the highest, middle, and the lowest groups of performers suggested a greater use of metacognitive strategies among successful learners and a greater use of surface level cognitive strategies among unsuccessful learners. Implications for the classroom and future research are also discussed.

Strategic considerations for a future sustainable energy system as well as an assessment of the ETH's strengths and its prospects for continuing research in areas highly relevant for the future are dealt with. It is noted that the Energy Science Center has contributed significantly to the integration of specialists and disciplines and has already become indispensable for the co-ordination of energy-relevant activities in research and teaching at the ETH in Zurich. Strategic goals are discussed, as are the challenges placed on the centre. Research done in the areas of energy supply and its use are discussed, as are interactions with society and the environment. Energy education at the ETH is examined and visions for a transformation path are discussed, as are the implications for the ETH itself

  9. An Energy Strategy for Canada

    Directory of Open Access Journals (Sweden)

    2015-10-01

    Full Text Available Canada is struggling to fully develop, sell and move its energy resources. This is a dramatic change from the recent past where the U.S. has provided stable growth in demand for energy supplied by the provinces, from hydrocarbons to electricity. Current circumstances now challenge this relationship, adding environmental, policy and economic hurdles that exacerbate the impact of fluctuations in world demand and pricing. In addition, competitive interaction between provinces, aboriginal land owners and special interest groups complicate and compound the issues of royalty returns, regulatory authority and direction, land-use management and long-term market opportunities for Canadian companies. There is no strategic document guiding the country’s energy future. As the steward of one of the largest, most diverse and valuable energy "banks" in the world, Canada has a unique opportunity to exploit a critical and valuable economic niche in the world economy. Given the lack of federal leadership and the tendency for each province to undercut each other in the same marketplace, there is also the distinct possibility the nation will squander the opportunity. This document offers the rationale for a comprehensive energy strategy, literally a vision where Canada can lead and not follow opportunities in energy markets. This strategic approach to energy systems by definition will include transportation, housing, employment and financial markets. It is not a plan, not a foil for tax or policy guidance in one or more sectors. This strategy is a fundamental rail on which plans, tactics and policies can be built. This vision identifies how the provinces can work together using all the tools available to them, maximizing long-term resource development while minimizing environmental damage. This document assumes there can be a broad commitment and effort by the federal government to help build those tools, providing guidance and assistance where needed without

  10. Angola - towards an energy strategy

    Despite an abundant endowment of energy resources, Angola's people and its economy suffer from lack of reliable energy supplies. In 2003, the country emerged from almost three decades of civil war that left much of its infrastructure destroyed or damaged and a large part of its population displaced. Increasing access to modern energy sources in a sustainable manner would help improve livelihoods directly, as well as indirectly through the promotion of economic development. At the request of the Angolan government in 2005, the IEA conducted a survey of the Angolan energy sector and energy policies. The request spurred several visits to Angola by IEA teams who met with energy sector officials and other stakeholders collecting documentation in the capital, Luanda and in Lubango. The results of these efforts are an independent review of the major energy policy issues facing the country. While Angola faces many energy challenges, there are lessons in this analysis that are applicable in many other developing countries. This inclusive review on Angola focuses on areas for priority action and hones in on energy sub-sectors likely to play the largest role in meeting domestic demand for modern energy services: notably electricity and oil products. As biomass currently plays an immense role in meeting the bulk of the energy needs of Angolan households, this sub-sector is also featured, with emphasis on improving the sustainability of this renewable energy source. A realistic update on Angola's present day energy situation is offered and the main priorities which could form the basis of an effective overall energy strategy are presented.

    Increasing legislative and consumer pressures on manufacturers to improve sustainability necessitates that manufacturers consider the overall life cycle and not be scope restricted in creating products. Product strategies to improve sustainability have design implications as many of the decisions made during the design stage will then determine the environmental performance of the final product. Coordination across the supply chain is potentially beneficial as products with improved energy ef...

  13. Department of Energy licensing strategy

    International Nuclear Information System (INIS)

    Frei, M.W.

    1984-01-01

    The Department of Energy (DOE) is authorized by the Nuclear Waste Policy Act of 1982 (Act) to site, design, construct, and operate mined geologic repositories for high-level radioactive wastes and is required to obtain licenses from the Nuclear Regulatory Commission (NRC) to achieve that mandate. To this end the DOE has developed a licensing approach which defines program strategies and which will facilitate and ease the licensing process. This paper will discuss the regulatory framework within which the repository program is conducted, the DOE licensing strategy, and the interactions between DOE and NRC in implementing the strategy. A licensing strategy is made necessary by the unique technical nature of the repository. Such a facility has never before been licensed; furthermore, the duration of isolation of waste demanded by the proposed EPA standard will require a degree of reliance on probabilistic performance assessment as proof of compliance that is a first of a kind for any industry. The licensing strategy is also made necessary by the complex interrelationships among the many involved governmental agencies and even within DOE itself, and because these relationships will change with time. Program activities which recognize these relationships are essential for implementing the Act. The guiding principle in this strategy is an overriding commitment to safeguarding public health and safety and to protecting the environment

    The Danish Government's long-term energy strategy follows up on the political agreement of 29 March 2004. The energy strategy is a coherent formulation of the Government's long-term energy policy. The pivotal point for the energy strategy is liberalized energy markets and market based tools for obtaining goals such as efficiency, security of supply and environment. The focus is increasingly on the substantial business potential within development of new and more efficient energy technology, in which Denmark takes up several globally strong positions. Furthermore, transportation energy consumption has been included directly in an energy strategy for the first time. At the same time as the energy strategy is presented, a summarizing background report from the Danish Energy Agency with facts, analyses and evaluations is published, as well as a report from energinet.dk that summarizes the system responsibilities' input to that part of the energy strategy that deals with power infrastructure.

    The research and development strategy for inertial fusion energy (IFE) is delineated. The development strategy must indicate how commercial IFE power can be made available in the first part of the next century, by which is meant that a Demonstration Power Plant (DPP) will have shown that in commercial operation IFE power plants can satisfy the requirements of public and employee safety, acceptably low impact on the environment, technical performance, reliability, maintainability and economic competitiveness. The technical issues associated with the various required demonstrations for each of the subsystems of the power plant (target, driver, reaction chamber, and remainder of plant (ROP) where the tritium for future targets is extracted and thermal energy is converted into electricity) are listed. The many developments required to make IFE commercially available can be oriented towards a few major demonstrations. These demonstrations do not necessarily each need separate facilities. The goals of these demonstrations are: (i) ignition demonstration, to show ignition and thermonuclear burn in an ICF target and determine the minimum required driver conditions; (ii) high gain demonstration, to show adequate driver efficiency-gain product; (iii) engineering demonstrations, to show high pulse rate operations in an integrated system and to choose the best designs of the various reactor systems; (iv) commercial demonstrations, to prove safe, environmentally benign, reliable, economic, near-commercial operation. In this document the present status of major inertial confinement research activities is summarized including a table of the major operating or planned facilities. The aspects involved in each of the required demonstrations are discussed. Also, for each of the subsystems mentioned above the technical developments that are needed are discussed. The document ends with a discussion of the two existing detailed IFE development plans, by the United States and Japan. 9

    Research and development (Research and Development) activities in controlled thermonuclear fusion have been carried out since the 60's of the last century aiming at providing a new clean, powerful, practically inexhaustive, safe, environmentally friend and economically attractive energy source for the sustainable development of our society.The EURATOM Fusion Programme (EFP) has the leadership of the magnetic confinement Research and Development activities due to the excellent results obtained on JET and other specialized devices, such as ASDEX-Upgrade, TORE SUPRA, FTU, TCV, TEXTOR, CASTOR, ISTTOK, MAST, TJ-II, W7-X, RFX and EXTRAP. JET is the largest tokamak in operation and the single device that can use deuterium and tritium mixes. It has produced 16 MW of fusion power, during 3 seconds, with an energy amplification of 0.6. The next steps of the EFP strategy towards fusion energy are ITER complemented by a vigorous Accompanying Programme, DEMO and a prototype of a fusion power plant. ITER, the first experimental fusion reactor, is a large-scale project (35-year duration, 10000 MEuros budget), developed in the frame of a very broad international collaboration, involving EURATOM, Japan, Russia Federation, United States of America, Korea, China and India. ITER has two main objectives: (i) to prove the scientific and technical viability of fusion energy by producing 500 MW, during 300 seconds and a energy amplification between 10 and 20; and (ii) to test the simultaneous and integrated operation of the technologies needed for a fusion reactor. The Accompanying Programme aims to prepare the ITER scientific exploitation and the DEMO design, including the development of the International Fusion Materials Irradiation Facility (IFMIF). A substantial part of this programme will be carried out in the frame of the Broader Approach, an agreement signed by EURATOM and Japan. The main goal of DEMO is to produce electricity, during a long time, from nuclear fusion reactions. The

Such strategies typically involve three major technological changes: energy savings on the demand side, efficiency improvements in the energy...... production, and replacement of fossil fuels by various sources of renewable energy. Consequently, large-scale renewable energy implementation plans must include strategies of how to integrate the renewable sources in coherent energy systems influenced by energy savings and efficiency measures. Based...... on the case of Denmark, this paper discusses the problems and perspectives of converting present energy systems into a 100 percent renewable energy system. The conclusion is that such development will be possible. The necessary renewable energy sources are present, if further technological improvements...

    Midilli, Adnan; Dincer, Ibrahim; Ay, Murat

    2006-01-01

    In this study we propose some green energy strategies for sustainable development. In this regard, seven green energy strategies are taken into consideration to determine the sectoral, technological, and application impact ratios. Based on these ratios, we derive a new parameter as the green energy impact ratio. In addition, the green energy-based sustainability ratio is obtained by depending upon the green energy impact ratio, and the green energy utilization ratio that is calculated using actual energy data taken from literature. In order to verify these parameters, three cases are considered. Consequently, it can be considered that the sectoral impact ratio is more important and should be kept constant as much as possible in a green energy policy implementation. Moreover, the green energy-based sustainability ratio increases with an increase of technological, sectoral, and application impact ratios. This means that all negative effects on the industrial, technological, sectoral and social developments partially and/or completely decrease throughout the transition and utilization to and of green energy and technologies when possible sustainable energy strategies are preferred and applied. Thus, the sustainable energy strategies can make an important contribution to the economies of the countries where green energy (e.g., wind, solar, tidal, biomass) is abundantly produced. Therefore, the investment in green energy supply and progress should be encouraged by governments and other authorities for a green energy replacement of fossil fuels for more environmentally benign and sustainable future

    The Republic of Croatia has been building the Krsko Nuclear Power Plant and is participating in all the activities necessary for a successful operating of the plant now for almost thirty years. However, in the light of the nuclear energy renaissance it is necessary to prepare ourselves for new challenges, stricter criteria of safety and protection, respect the indispensability of continuous re-examination of safety of procedures and methods. The of Croatia has strictly committed herself to the nuclear energy programme development-CRONEP in accordance with the methodology of the International Atomic Energy Agency. Certainly, in the first moment till the possible decision on the building of nuclear power plant, it will be necessary to make an institutional framework and create human resources and such an infrastructure that will be able to, when the decision will be taken, support the project and realize it with maximal efficiency. We consider it the unique way in which it is possible to avoid what proved to be the weakness of some projects of nuclear power plants, that is missing a deadline and problems concerning financing that are intolerable taking into account the value of the investment. Likewise, since the Conference is dedicated to small and medium-sized electric networks or to small nuclear power programmes, it needs to be mentioned that except the largest facilities it should be promoted researching of nuclear power reactors of medium size whose development somehow falls behind in this moment Medium size reactors gives great advantages to smaller economies in technical and financial sense. From the current standpoint solutions of viability of nuclear programmes through re-processing of the spent nuclear fuel in new generation of power plants are discernible. Since today's technologies are sufficiently safe there is no need to wait with this development and fuel from one generation shall be re-processed into the fuel for the next generation of reactors.

    Breastfeeding women may experience disrupted sleep schedules and be tempted to turn to popular energy drinks to reduce fatigue and enhance alertness, prompting the question: What are the maternal and child health implications for breastfeeding mothers consuming energy drinks? Caffeine and vitamin-rich energy drinks contain a variety of herbal ingredients and vitamins; however, ingredient amounts may not be clearly disclosed on product labels. Interactions between herbal ingredients and caffeine are understudied and not well defined in the literature. Some infants can be sensitive to caffeine and display increased irritability and sleep disturbances when exposed to caffeine from breastmilk. Breastfeeding women who consume energy drinks may be ingesting herbal ingredients that have not undergone scientific evaluation, and if taking prenatal vitamins, may unknowingly exceed the recommended daily intake. Caffeinated products are marketed in newer ways, fueling concerns about health consequences of caffeine exposure. We present implications associated with consumption of caffeine and vitamin-rich energy drinks among breastfeeding women. Product safety, labeling, common ingredients, potential interactions, and clinical implications are discussed. Healthcare providers should encourage breastfeeding women to read product labels for ingredients, carbohydrate content, serving size, and to discourage consumption of energy drinks when breastfeeding and/or taking prenatal vitamins, to avoid potential vitamin toxicity.

    In the course of developing the National Energy Strategy, the Department of Energy held 15 public hearings, heard from more than 375 witnesses and received more than 1000 written comments. In April 1990, the Department published an Interim Report on the National Energy Strategy, which compiles those public comments. The National Energy Strategy must be based on actual experience and factual analysis of our energy, economic and environmental situation. This report by the Nuclear Power Oversight committee, which represents electric utilities and other organizations involved in supplying electricity from nuclear energy to the American people, provides such an analysis. The conclusions here are based on hard facts and actual worldwide experience. This analysis of all the available data supports -- indeed, dictates -- expanded reliance on nuclear energy in this nation's energy supply to achieve the President's goals. 33 figs

    The results of two quantitative scenarios balancing global energy supply with demand for the period 1980-2030 are reviewed briefly. The results suggest that during these 50 years there will be a persistent demand worldwide for liquid fuels, a continuing reliance on ever more expensive and ''dirty'' fossil fuels, and a limited penetration rate of nuclear generated electricity into the energy market. The paper therefore addresses a possible ''second'' grid driven by nuclear heat - a grid based not on electricity but on ''clean'' liquid fuels manufactured from gaseous and solid fossil fuels using nuclear power. Such a second grid would be an important complement to the electricity grid if the world is to progress towards a truly sustainable energy system after 2030

    2010-01-01

    The following article will analyse the global and geopolitical dimensions of the future international energy security and its implications for Europe and the EU-27. In this context, I will discuss to which extent the EU's newly proclaimed 'Energy Action Plan' of the EU Spring summit of 2007 and its declared common energy (foreign) policy are a sufficient strategy to cope with the new global and geopolitical challenges. The article concludes the following: (1) The interlinkage between globally designed traditional energy security concepts - that rely just on economic factors and 'market-strategies' - and domestic as well as regional political stability demands new thinking with regard to both energy supply security and foreign and security policies. (2) Although after the Russian-Ukrainian gas conflict in January 2006, energy security has forced its way up the European energy and foreign policy agendas, the EU-27 member states have largely failed to forge a coherent European energy security and energy foreign policy strategy after their Spring summit of 2007 because its declared political solidarity has been still lacking. But the 2nd Strategic Energy Review of November 2008 has recommended new initiatives to overcome this lack by promoting concrete infrastructure and other projects for enhancing Europe's supply security and its political solidarity as part of a common energy (foreign) policy. If the EU is able to implement the March 2007 and November 2008 decisions, the EU oil and gas demand will drastically reduce and freeze at current levels. In this case, Putin's energy policies by using Russia's energy resources and pipeline monopolies as a political instrument to enforce its economic and geopolitical interests will be proved as self-defeating in Russia's long-term strategic interests. It will reduce Gazprom's gas exports to a much smaller EU gas market than originally forecasted as the result of a deliberate EU policy of decreasing its overall gas demand and

    This paper will summarise the European Strategy for Energy and Climate Change. In current international negotiations Europe has proposed a 20% reduction in GHG (greenhouse gases) in the developed countries by 2020 or 30% should there be an international agreement in the domain. However it is important to define measures to achieve the targets. One of the principal tools is to improve energy efficiency under the energy efficiency action plan, which will help to achieve a 20% energy saving by 2020. On the other hand, the amount of energy from renewable sources consumed in Europe will have to rise from its current level of 8.5%–20% by 2020. These are ambitious but achievable targets. Nonetheless, these can only be achieved through strong investment in areas of the knowledge triangle which strengthens research and innovation in the energy sector in Europe. The paper covers European Energy and Climate Change Policy, the European Strategic Energy Technology plan, the consequences of the Lisbon Treaty, European and national Road maps to a low carbon economy, the Energy Efficiency Plan for 2011 and finishes with a brief consideration of the EU’s energy infrastructure priorities. -- Highlights: ► This paper summarises the European Strategy for Energy and Climate Change. ► Reduction of GHG emissions by 30%-international agreement or −20% without agreement. ► Use of 20% of renewable energies by 2020. ► Increase of energy efficiency of 20% by 2020. ► Consolidating of the internal energy market.

    The twenty-first century has dawned; with it the third millennium. This is indeed a significant milestone in human history and an occasion for all of us for reflection and change. The model of development followed so far has relied excessively on consumption of fossil fuels, and this has endangered the biodiversity and the ecology of the earth. On this World Environment Day, I think it's our duty to resolve that we should leave the earth, if not in a better state that what we came into, then at least at the same state as we came in. It is against the backdrop of increasing environmental degradation where, around the world, there has been an increased emphasis on renewable energy. If the current interest in renewable energy products gets concretized, the twenty-first century can be expected to be as profoundly shaped by the move away from fossil fuels as the twentieth century was by the move towards them.

    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

    Traditional management of electricity portfolios is focused on the day-ahead market and futures of longer maturity. Within limits, market participants can however also resort to the balancing energy market to close their positions. In this paper, we determine strategic positions in the balancing energy market and identify corresponding economic incentives in an analysis of the German balancing energy demand. We find that those strategies allow an economically optimal starting point for real-time balancing and create a marketplace for flexible capacity that is more open than alternative marketplaces. The strategies we proffer in this paper we believe will contribute to an effective functioning of the electricity market. (author)

    2015-06-01

    Full Text Available The energy sector in Romania consists of three sub-sectors: electricity, natural gas and heat. Among these, the sub-sector of thermal energy is in the most precarious situation because it has been neglected for a long time. This sub-sector is particularly important both due to the amount of final heat consumption (of over 50% of final energy consumption, and to the fact that it has a direct negative effect on the population, industry and services. This paper presents the main directions for developing a modern strategy of the thermal energy sub-sector, which would fit into Romania’s Energy Strategy that is still in preparation This is based on the author’s 50 years of experience in this field that includes knowledge about the processes and the equipment of thermal energy, expertise in the management and restructuring of energy companies and also knowledge of the specific legislation. It is therefore recommended, following the European regulations and practices, the promotion and upgrading of district heating systems using efficient cogeneration, using trigeneration in Romania, modernizing buildings in terms of energy use, using of renewable energy sources for heating, especially biomass, and modernizing the energy consumption of rural settlements.

    In the introductory part of the strategy for the development of energy until 2015 the specifications of the present-day energy sector are given: strengths and weaknesses, opportunities for further development, which are expedient to be used, and threats, which are necessary to be reduced as much as possible. A vision of the energy sector and State mission, i.e., the main provisions and trends of State activities, which would allow the implementation of the desirable development of energy, are also formulated. The main strategic goals are identified with the consideration taken of essential requirements and provisions of the European Association Agreement, the Energy Charter Agreement, and other international agreements in the field of energy. Special attention in the strategy is devoted to the identification of the main trends in the development of the energy sector. A number of factors, both external and internal, will have an effect on the development of Lithuania's economy in the future. In preparing this strategy three scenarios of economic growth will be possible: 1) fast economic growth scenario (5.7 percent per year, on the average, in 2000-2015); 2) the main scenario (4.1 percent); 3) slow economic growth scenario (2.3 percent). Forecasts for the needs of energy for the said economic scenarios are prepared with the application of the MAED model, taking into consideration the expected structural changes in the GDP, energy intensity changes, the development of social indices, and other factors, having an effect on the changes in the consumption of energy. The duration of exploitation of the Ignalina NPP will have an essential effect on the development of the electric energy system. On the basis of optimisation calculations, performed with the use of the WASP-4 model, the strategy presents a detailed analysis of different scenarios for the shutdown of the nuclear power plant and expenses of its replacement by other electric power plants.

    This paper presented a vision with respect to a continental energy strategy and the principles and goals that must underlie such a strategy. These principles include relying on signals emanating from energy markets to guide investment; limiting the role of government to that of ensuring that the policy and institutional framework is conducive to the development and operation of competitive and innovative energy markets; and ensuring free and open energy trade in energy commodities, both within the continent and with the rest of the world. The paper also identified a number of important factors that, would shape and condition continental energy development and trade. The paper provided an overview of the North American energy use and supply situation for the following resources: oil; natural gas; electricity; coal; nuclear power; hydroelectricity; geothermal energy; wind power; solar power; and ethanol. It also discussed the contribution of the North American Free Trade Agreement (NAFTA) through increased natural gas exports. It was concluded that given the petroleum resources of the three countries and their increased value because of higher oil and gas prices, there was considerable incentive for Canada, the United States, and Mexico to streamline regulations in order to facilitate the efficient development, transportation, and use of the continent's energy resources in accordance with market conditions. 38 refs., 2 tabs., 21 figs

    1997-01-01

    As discussed in this conference paper, the goal of Finnish energy strategy is to bring the growth of the total energy consumption to a halt in the next 10-15 years and to speed up the restructuring of the energy economy without hampering economic growth. By 2010 the emission of greenhouse gases should be down to the 1990 level. To reach the goals, various means are available: taxation, subsidies, energy efficiency measures, replacing fossil sources with renewable and low-emission energy sources. By 1999 Finland should be connected to the European gas network. The use of bioenergy, wood fuels and wind power is encouraged. Peat is a competitive fuel in areas where it is locally available. To cut down on CO 2 emission it is necessary to increase the use of bioenergy, and by 2025 the use of wood will have increased considerably from the present level. At present, the wood reserves increase by one percent per year. Public funds will be set aside for energy wood research, for product development and marketing. Peat is an important indigenous energy resource, accounting for about 5% of all energy use. The Government is committed to closely follow up the implementation of its energy strategy. 1 ref., 3 figs

    Full Text Available Executive Functions (EF concern a range of abilities including problem-solving, planning, initiation, selfmonitoring,conscious attention, cope with new situations and the ability to modify plans if necessary. It’s a high cognitive function that is crucial for a person to get engaged and maintain daily activities whilst keeping a good quality of life. Problems in the EF were formerly known as Dysexecutive Syndrome (DS. There are many models concerning DS, although the literature on the subject still remains unclear. Several works appoint the effects brought by elderly life, as well as abuse of drugs and some psychopathologies. These factors are known to increase the distress of the frontal circuits and that could be associated to executive deficits. The effects of DS would compromise individuals in day-to-day routine, academic, social and labor fields. There is a growing body of studies trying to determine the causes, implications, associations and the best way to take care of these effects. This work intends to review DS, focusing on the most important fields related to this area, such as psychopathology associations, cognitive reserve, assessment and cognitive rehabilitation programs.

  14. Energy in Ireland: context, strategy and research

    Saintherant, N.; Lerouge, Ch.; Welcker, A.

    2008-01-01

    In the present day situation of sudden awareness about climatic change and announced fossil fuels shortage, Ireland has defined a new strategy for its energy future. Context: Ireland is strongly dependent of oil and gas imports which increase regularly to meet the demand. A small part of the electricity consumed is imported from Ulster. The share of renewable energies remains weak but is increasing significantly. Therefore, from 1990 to 2006, the proportion of renewable energies increased from 1.9% (mainly of hydroelectric origin) to 4.5%. Wind power represents now the main renewable energy source. The transportation sector is the most energy consuming and the biggest source of greenhouse gases. Strategy: the Irish policy is driven by pluri-annual strategic plans which define the objectives and means. Priority is given to the security of supplies at affordable prices: 8.5 billion euros will be invested during the 2007-2013 era for the modernization of existing energy infrastructures and companies, and in a lesser extent for the development of renewable energy sources. During this period, 415 million euros more will be devoted to the research, development and demonstration (RD and D) of new energy solutions. Research: in 2005 the energy RD and D expenses reached 12.8 million euros shared between 54% for R and D and 46% for demonstration projects. Half of the financing is given to higher education schools and is devoted to energy saving purposes (33%) and to renewable energies (29%, mainly wind power and biomass). Academic research gives a particular attention to ocean energy which represents an important potential resource in Ireland and which has already led to the creation of innovative companies. The integration of renewable energy sources to the power grid and the stability of supplies are also the object of active researches. (J.S.)

    With the proliferation of mobile streaming multimedia, available battery capacity constrains the end-user experience. Since streaming applications tend to be long running, wireless network interface card's (WNIC) energy consumption is particularly an acute problem. In this work, we explore the WNIC energy consumption implications of popular multimedia streaming formats from Microsoft (Windows media), Real (Real media) and Apple (Quick Time). We investigate the energy consumption under varying stream bandwidth and network loss rates. We also explore history-based client-side strategies to reduce the energy consumed by transitioning the WNICs to a lower power consuming sleep state. We show that Microsoft media tends to transmit packets at regular intervals; streams optimized for 28.8 Kbps can save over 80% in energy consumption with 2% data loss. A high bandwidth stream (768 Kbps) can still save 57% in energy consumption with less than 0.3% data loss. For high bandwidth streams, Microsoft media exploits network-level packet fragmentation, which can lead to excessive packet loss (and wasted energy) in a lossy network. Real stream packets tend to be sent closer to each other, especially at higher bandwidths. Quicktime packets sometimes arrive in quick succession; most likely an application level fragmentation mechanism. Such packets are harder to predict at the network level without understanding the packet semantics.

    Nova Scotia's energy strategy addresses all aspects of energy production and use, from offshore oil and gas to electricity and coal, to climate change and renewable resources. It also encompasses energy conservation and efficiency. This progress report highlights the efforts that the province has made to promote exploration, improve efficiency of regulations and approval processes and promote the oil and natural gas sector. Efforts have also been made to support local businesses, address climate change issues and protect the environment. The strategy demonstrates how new energy resources can be used to build a more prosperous and self-reliant province. The progress report focuses on the following 3 themes: powering the economy; improving the environment; and, securing Nova Scotia's future. The report emphasizes that the growing oil and gas industry brings many opportunities for new jobs and a stronger economy. In the next 12 to 18 months, about 8 to 10 offshore exploration wells will be drilled, which is more than in the last decade. Funding will be provided to extend pipeline systems beyond franchise areas approved by the Nova Scotia Utility and Review Board. In May 2002, the Electricity Marketplace Governance Committee was formed to make recommendations on how competition can be introduced into the province's electricity market. The Department of Energy has been working to implement initiatives to increase the use of renewable energy sources such as solar and wind power. In October 2002, new wind turbines began producing electricity in 3 communities on Cape Breton Island. A key priority is to respond to climate change and reduce greenhouse gas emissions as well as emissions of mercury, sulphur, nitrogen, and ozone. The energy strategy also identifies the need to provide competitive taxation regimes.

    1992-03-01

    This study reviews the environmental implications of continued and increased use of biomass for energy to determine what concerns have been and need to be addressed and to establish some guidelines for developing future resources and technologies. Although renewable biomass energy is perceived as environmentally desirable compared with fossil fuels, the environmental impact of increased biomass use needs to be identified and recognized. Industries and utilities evaluating the potential to convert biomass to heat, electricity, and transportation fuels must consider whether the resource is reliable and abundant, and whether biomass production and conversion is environmentally preferred. A broad range of studies and events in the United States were reviewed to assess the inventory of forest, agricultural, and urban biomass fuels; characterize biomass fuel types, their occurrence, and their suitability; describe regulatory and environmental effects on the availability and use of biomass for energy; and identify areas for further study. The following sections address resource, environmental, and policy needs. Several specific actions are recommended for utilities, nonutility power generators, and public agencies.

    1995-01-01

    This personal history spans a half century of participation in the frontiers of applies science and engineering ranging from the nuclear weapons project of World War II, through the development of nuclear power, engineering education, and risk analysis, to today's energy research and development. In each of these areas, this account describes some of the exciting opportunities for technology to contribute to society's welfare, as well as the difficulties and constraints imposed by society's institutional and political systems. The recounting of these experiences in energy research and development illustrates the importance of embracing social values, cultures, and environmental views into the technologic design of energy options. The global importance of energy in a rapidly changing and unpredictable world suggests a strategy for the future based on these experiences which emphasizes the value of applied research and development on a full spectrum of potential options

    Lubin, Philip

    2016-09-01

    We compute the detectability of directed-energy (DE) sources from distant civilizations that may exist. Recent advances in our own DE technology suggest that our eventual capabilities will radically enhance our capacity to broadcast our presence and hence allow us to ponder the reverse case of detection. We show that DE systems are detectable at vast distances, possibly across the entire horizon, which profoundly alters conceivable search strategies for extra-terrestrial, technologically-advanced civilizations. Even modest searches are extremely effective at detecting or constraining many civilization classes. A single civilization anywhere in our galaxy of comparable technological advancement to our own can be detected with near unity probability with a cluster of 0.1 m telescopes on Earth. A 1 m class telescope can detect a single civilization anywhere in the Andromeda galaxy. A search strategy is proposed using small Earth-based telescopes to observe 1012-1020 stellar and planetary systems. Such observations could address whether there exist other civilizations which are broadcasting with similar or more advanced DE capability. We show that such searches have near-unity probability of detecting comparably advanced civilizations anywhere in our galaxy within a few years, assuming the civilization: (1) adopts a simple "intelligent targeting" beacon strategy; (2) is beaconing at a wavelength we can detect; (3) broadcast the beacon long enough for the light to reach Earth now. In this blind-beacon, blind-search strategy, the civilization need not know where we are nor do we need to know where they are. The same basic strategy can be extended to extragalactic distances.

    2008-01-15

    In the present day situation of sudden awareness about climatic change and announced fossil fuels shortage, Ireland has defined a new strategy for its energy future. Context: Ireland is strongly dependent of oil and gas imports which increase regularly to meet the demand. A small part of the electricity consumed is imported from Ulster. The share of renewable energies remains weak but is increasing significantly. Therefore, from 1990 to 2006, the proportion of renewable energies increased from 1.9% (mainly of hydroelectric origin) to 4.5%. Wind power represents now the main renewable energy source. The transportation sector is the most energy consuming and the biggest source of greenhouse gases. Strategy: the Irish policy is driven by pluri-annual strategic plans which define the objectives and means. Priority is given to the security of supplies at affordable prices: 8.5 billion euros will be invested during the 2007-2013 era for the modernization of existing energy infrastructures and companies, and in a lesser extent for the development of renewable energy sources. During this period, 415 million euros more will be devoted to the research, development and demonstration (RD and D) of new energy solutions. Research: in 2005 the energy RD and D expenses reached 12.8 million euros shared between 54% for R and D and 46% for demonstration projects. Half of the financing is given to higher education schools and is devoted to energy saving purposes (33%) and to renewable energies (29%, mainly wind power and biomass). Academic research gives a particular attention to ocean energy which represents an important potential resource in Ireland and which has already led to the creation of innovative companies. The integration of renewable energy sources to the power grid and the stability of supplies are also the object of active researches. (J.S.)

    2015-01-01

    Abstract Mitochondrial function and specifically its implication in cellular redox/oxidative balance is fundamental in controlling the life and death of cells, and has been implicated in a wide range of human pathologies. In this context, mitochondrial therapeutics, particularly those involving mitochondria-targeted antioxidants, have attracted increasing interest as potentially effective therapies for several human diseases. For the past 10 years, great progress has been made in the development and functional testing of molecules that specifically target mitochondria, and there has been special focus on compounds with antioxidant properties. In this review, we will discuss several such strategies, including molecules conjugated with lipophilic cations (e.g., triphenylphosphonium) or rhodamine, conjugates of plant alkaloids, amino-acid- and peptide-based compounds, and liposomes. This area has several major challenges that need to be confronted. Apart from antioxidants and other redox active molecules, current research aims at developing compounds that are capable of modulating other mitochondria-controlled processes, such as apoptosis and autophagy. Multiple chemically different molecular strategies have been developed as delivery tools that offer broad opportunities for mitochondrial manipulation. Additional studies, and particularly in vivo approaches under physiologically relevant conditions, are necessary to confirm the clinical usefulness of these molecules. Antioxid.

    1996-01-01

    The key to successful development of renewable energies in Romania requires a combination of political commitment and decision making as well as support mechanism including well defined government targets, technological advances and public acceptance. Overall short, medium and long term targets and required funding are recommended while expected benefits are estimated. Public funds in the form of grants and subsidies to promote and support RES constitute one of the best investments in the national economy. Commercial investments in RES will contribute to the country's balance of payments as well as towards the environmental protection. Therefore these actions may be supported through a special fund, in particular designed for RES and energy conservation investments. As a first step towards the commercialization of RES a short term action plan needs to be implemented for achieving the set forth long term objectives. This plan includes promising projects for the demonstration of technologically and economically viable applications in each RES sector as well as institutional and other soft measures .The RES promotional policy measures have to be translated into concrete legislation providing the necessary framework into which the sector will operate with transparency and open competitiveness. One of the key policies for RES strategy is to organize a flexible and efficient scheme for the implementation of the policy adopted by the government. The total rural population, together with the urban population living in medium sized towns will be considered as the primary market segment for RES applications (about 61 % of total population).

    Domestic commercial airplane fuel use is examined as a function of stage length. A fuel use model is developed using the eight most popular airplanes. Short flights are very fuel inefficient; a 100-mile flight consumes 2.5 times as much fuel per passenger-mile than a 1,000-mile flight. Half of today's flights are for distances under 260 miles. Fuel consumption for purposes other than flying directly between airports is examined. Over 10% of total fuel use is for those portions of the flight in which no enroute distance is achieved. Delays account for at least 4.2% of the fuel consumption and auxiliary power units use over 1%. Fuel requirements for attempting to recover lost time and for fuel ferrying are also discussed. Airplane fuel efficiency can be increased in the short term by operational changes, particularly by increasing the load factor. A load factor increase from 50 to 60% would reduce airplane fuel use by 16% for the same traffic. Other options include reducing cruise speeds, increasing cruise altitudes, and changing ground operations. Each of these strategies offer savings of 1 to 3%. Total transportation energy use can be reduced by shifting air passengers to ground modes, especially for the inefficient short-stage traffic. Net energy savings for diverting half the flights under 200 miles to buses or trains is equivalent to 6% of the fleet fuel use. (6 tables, 6 fig., 36 references)

    , a construction of 20000 windmills of 1 MW nominal power, or of 8000 of 2.5 MW every year. This is a truly staggering task, far beyond the capabilities of existing European producers. It requires first an agreement on national targets and then urgent development of relevant industries. As for the solar contribution, a technological breakthrough that would make it economic for a large-scale power production is not in sight, at least not before 2020. Any delay in construction of required renewable capacities and in consumption limitation will require compensating increase of nuclear power in order that the 20 percent reduction of CO 2 emission target be achieved. Unless the bodies responsible for EU energy strategy can provide a convincing technological and industrial program and timetable for the construction of required number of wind and solar power stations by 2020, together with implementation of measures for reduction of energy consumption, they must very soon give clear signals to nuclear industry to have it ready to built the nuclear power station needed to keep 20 percent reduction in CO 2 emission. Failing this a nuclear chance to achieve a targeted CO 2 decrease by 2020 could be forfeited as well.(author)

    Primary copper production is a major activity in the mining sector. It is highly energy-intensive, ranking third in specific energy consumption (SEC) among the five major basic metals (aluminum, copper, iron, lead and zinc) and poses important environmental hazards. We examine the large discrepancy between theoretical (from thermodynamics) and actual (from empirical data) SECs and then describe relevant environmental issues, focusing on the most significant energy-related environmental impacts of primary copper production with emphasis on greenhouse-gas (GHG) emissions. An example of GHG energy-related abatement that concurrently improves energy use is presented. (Author)

    Technical change is a key factor in the energy world. Failure to recognize the potential for technical change, and the pace at which it may occur, has limited the accuracy and usefulness of past energy projections. conversely, programs to develop and deploy advanced energy technologies have often proved disappointing in the face of technical and commercial obstacles. This book examines important new and emerging energy technologies, and the mechanisms by which they may develop and enter the market. The project concentrates on the potential and probable role of selected energy technologies-which are in existence and likely to be of rapidly growing importance over the next decade-and the way in which market conditions and policy environment may affect their implementation

    2003-01-01

    This paper summarizes an assessment of future energy-technology strategies for China that explored the prospects for China to continue its social and economic development while ensuring national energy-supply security and promoting environmental sustainability over the next 50 years. The MARKAL energy-system modeling tool was used to build a model of China's energy system representing all sectors of the economy and including both energy conversion and end-use technologies. Different scenarios for the evolution of the energy system from 1995 to 2050 were explored, enabling insights to be gained into different energy development choices. The analysis indicates a business-as-usual strategy that relies on coal combustion technologies would not be able to meet all environmental and energy security goals. However, an advanced technology strategy emphasizing (1) coal gasification technologies co-producing electricity and clean liquid and gaseous energy carriers (polygeneration), with below-ground storage of some captured CO 2 ; (2) expanded use of renewable energy sources (especially wind and modern biomass); and (3) end-use efficiency would enable China to continue social and economic development through at least the next 50 years while ensuring security of energy supply and improved local and global environmental quality. Surprisingly, even when significant limitations on carbon emissions were stipulated, the model calculated that an advanced energy technology strategy using our technology-cost assumptions would not incur a higher cumulative (1995-2050) total discounted energy system cost than the business-as-usual strategy. To realize such an advanced technology strategy, China will need policies and programs that encourage the development, demonstration and commercialization of advanced clean energy conversion technologies and that support aggressive end-use energy efficiency improvements

    Chinese regional disparities are readily apparent, with well-being seen the highest at the coast and declining steadily inland. Their mitigation will clearly be hostage to improvement in economic development, since the unevenness of that development created them in the first place. Integral to development is structural change, and the key to effecting that change is improved energy efficiency. Indeed, this paper explores energy usage and regional development from 1952 to the present, establishing that they both conform to an inverted-U pattern. Eastern China, the leader in industrialization, has moved beyond the apogee of the curve, but Central and Western China have failed to follow suit, being held back by poor industrial structures and adverse patterns of energy consumption. Remedying this laggardly performance preoccupies China's Government, for rendering the country energy-efficient and containing regional disparities, both rest on pushing the Central and Western regions down the curve in the wake of the prosperous coast.

    Emphasis in the report is placed on how to cope with the stringent situation of energy resources in Japan when the energy demands are rising with the advance of economies. For the future, countermeasures must be taken in time and on firm basis. The characteristics of respective energy resources are clarified, and on this basis, review is made on the energy supplies up to the beginning of the 21st century. In the above connection, the following measures are taken up: promotion of energy saving, stable supply of petroleum, development and utilization of substitute energies, development of technologies for new energies, enhancement in the location of power stations, and securing of the necessary funds. In conclusion, it points out the need for further efforts on overall energy measures and the need for full co-ordination of the energy policy with the social situation. (Mori, K.)

    This article synthesizes the main projection results for final use of energy consumed by light transportation vehicles on the next 20 years in Brazil, and evaluates their implications for a strategy of energetic sustainable development in Brazil. Arising out from previous studies performed for the Petroleum Brazilian Institute, for he Brazilian Ministry of Mines and Energy and for the IAEA, this article considers two sceneries: reference (REF) which considers significant changes, beyond those already consolidated; alternative (ALT), which considers progressive changes in the modal of transportation, in the energy efficiency and a augmented participation of 'clean' energy sources. Both sceneries estimates potential growing of light vehicles fleet, gain of energetic efficiency and a participation of bio fuels and VNG in Brazil, and the rhythm of the implementation. The results show the the difference between the final use of energy by light vehicles in REF (44 MtEP) in 2023 and in ALT (40 MtEP in 2023) can reach almost 10% during the next 20 years.

    In 1992, Congress sought to rewrite the United States comprehensive solid waste legislation -- the Resource Conservation and Recovery Act (RCRA). Commodity-specific recycling rates were proposed for consumer-goods packaging materials and newsprint We compare the impacts on energy, materials use, and landfill volume of recycling at those rates to the impacts for alternative methods of material disposition to determine the optimum for each material. After products have served their intended uses, there are several alternative paths for material disposition. These include reuse, recycling to the same product, recycling to a lower-valued product, combustion for energy recovery, incineration without energy recovery, and landfill. Only options considered to be environmentally sound are Included. Both houses of Congress specifically excluded combustion for energy recovery from counting towards the recovery goats, probably because combustion is viewed as a form of disposal and is therefore assumed to waste resources and have n environmental effects. However, co-combustion in coal-fired plants or combustion in appropriately pollution-controlled waste-to-energy plants Is safe, avoids landfill costs, and can displace fossil fuels. In some cases, more fossil fuels can be displaced by combustion than by recycling. We compare the alternative life-cycle energies to the energies for producing the products from virgin materials. Results depend on the material and on the objective to be achieved. There are trade-offs among possible goals. For instance, paper packaging recycling conserves trees but may require greater fossil-fuel input than virgin production. Therefore, the objectives for proposed legislation must be examined to see whether they can most effectively be achieved by mandated recycling rates or by other methods of disposition. The optimal choices for the United States may not necessarily be the same as those for Europe and other parts of the world.

  16. Welfare implication of reforming energy consumption subsidies

    2016-01-01

    Reforming energy consumption subsidies, in particular for fossil fuels, has been frequently referred to as a quick-win policy to enhance environmental mitigation. In addition, the removal of such subsidies may release a sizeable portion of a country's national budget for use on more productive targets. One of the most recognized challenges of such reform is “selling” the new energy prices to citizens, particularly those with a more fragile purchasing power. Several empirical and technical studies have prescribed that the reform might be supported by a direct compensation mechanism in order to ensure feasibility. This is what was done during the recent energy subsidy reform in Iran. However, the compensation mechanism implemented in Iran's reform was successful at the beginning, but did not proceed as expected. This has raised questions about the feasibility and sustainability of the direct compensation mechanism, and even of the reform policy itself. In this paper, we consider a stylized model where direct compensation is the instrument proposed to restore consumers’ utility against increased energy prices. We find that, when prices of Other Goods are affected by the announced reform policy, the feasibility of a subsidy reform critically depends on the value of certain parameters: the initial subsidization rate, the share of energy in the consumers’ bundle, and the energy portion of price of Other Goods. - Highlights: • A model of energy subsidy reform with direct compensation is proposed. • Feasibility of the reform is related to three key parameters. • An illustrative example using data from the recent Iranian reform is discussed.

  17. Energy implications of an aging population

    1980-08-01

    This study provides various demographic, medical, and economic information relative to energy usage on a segment of the population, the elderly, which is growing in absolute numbers and relative population percentage. This growth is expected to continue well into the twenty-first century. The US aging population numbered 3.1 million in 1900, and by 1977 it had climbed to 23.5 million. It can be stated with reasonable certainty that this figure will rise to 31 million in the year 2000 and 43 million in the year 2020. These figures, corresponding to more than 10% of our population, are by no means insignificant. As our fossil-fuel reserves are being depleted and the cost of energy mounts, it becomes apparent that the elderly will become increasingly vulnerable to the energy crisis, primarily beause of their physical tendency to infirmity, their economic and social situation, and their susceptibility to psychological depression. This white paper concentrates on those aspects of aging and the nation's energy problem which are not usually related in our everyday consideration of these as separable problems. It seeks to identify the peculiar energy problems of the aged and to consider alternatives in the solution of these problems in light of modern technology.

The European Union should support research in the field, apply more efficient policies in energy, and create economies of scale to get an integrated European energy market in which the main actors can reduce the cost of production of renewable energy. In addition, it is possible to use the comparative advantages of the Member States and not only, like Greece, through solar energy, Southern Mediterranean, through distribution networks interconnections with EU, Russia and Ukraine, through biomass and the North Sea, through wind energy. This paper refers to the evolution and trends of the renewable energy sources and presents some scenarios of it.

  19. Energy Implications of Seawater Desalination (Invited)

    Freshwater has traditionally come from rivers, lakes, streams, and groundwater aquifers. As demand increases and climate change alters the location and timing of water supply, these traditional sources are becoming unavailable, more difficult, or increasingly expensive to develop. As a result, many communities are switching to alternative sources of water. Interest in pursuing seawater desalination is high in many coastal communities. In California, for example, 17 plants are proposed for development along the California coast and two in Mexico. Water managers are pursing desalination because is a local supply that can help diversify the water supply portfolio. Additionally, it is a reliable supply, which can be especially valuable during a drought. But removing the salt from seawater is an energy-intensive process that consumes more energy per gallon than most other water supply and treatment options. These energy requirements are key factors that will impact the extent and success of desalination in California. Energy requirements for seawater desalination average about 4.0 kWh per cubic meter (m3) of water produced. By comparison, the least energy-intensive options of local sources of groundwater and surface water require 0 - 0.90 kWh per m3; wastewater reuse, depending on treatment levels, may require from 0.26 - 2.2 kWh per m3. Beyond the electricity required for the desalination facility itself, producing any new source of water, including through desalination, increases the amount of energy required to deliver and use the water produced as well as collect, treat, and dispose of the wastewater generated. Energy is the largest single variable cost for a desalination plant, varying from one-third to more than one-half the cost of produced water. Building a desalination plant may reduce a water utility's exposure to water reliability risks at the added expense of an increase in exposure to energy price risk. In dependent on hydropower, electricity prices tend to

    This paper presents a model of the Romanian energy system with the purpose of providing a tool for the analysis of future sustainable energy strategies. The model represents the total national energy system and is detailed to the level of hourly demand and production in order to be able to analyse...... the consequences of adding fluctuating renewable energy sources to the system. The model has been implemented into the EnergyPLAN tool and has been validated in order to determine if it can be used as a reference model for other simulations. In EnergyPLAN, two different future strategy scenarios for the Romanian...... energy system are compared to the actual data of Romania of year 2008. First, a comparison is made between the 2008 model and the 2013 strategy scenario corresponding to the grid of the Romanian transmission system operator (TSO) Transelectrica. Then, a comparison is made to a second strategy scenario...

  1. Japan's energy future: implications for Australia

    International Nuclear Information System (INIS)

    1999-01-01

    In April this year, the Department of Industry, Science and Resources published a report outlining the dilemmas facing Japan's energy industry in the post-Kyoto environment with particular reference to the effect it would have on Australia's fuel exports. The following article is based on information in that report. In summary, the extent to which the Japanese government's current climate change response policy (the long term energy forecast) is realised will depend on a complex interaction of competing considerations: 1. whether, in the event of US non ratification, the government maintains its Kyoto commitment or opts for a partial step back from its 8% commitment (and the extent of that draw back); 2. in the event that it does maintain its Kyoto commitment: a) the extent to which it takes advantage of the flexible mechanism provisions to ease the abatement burden on the energy system; b) the level of success in securing additional nuclear power stations and higher load ratios from nuclear power; c) the degree to which renewable and recycling energy sources can be brought on line; d) the extent to which the Japanese people are willing to meet the costs of switching to new technology and changing lifestyles to conserve energy; e) the timing of new initiatives such as emissions trading; the extent to which Japanese industry is able to achieve very strict energy conservation targets; f) the extent to which Japan's economic recovery leads to increased electricity demand as well as g) the extent to which electricity deregulation reduces prices and promotes increased consumption

    We study the phenomenological implications of effective supergravities based on string vacua with spontaneously broken N =1 supersymmetry by dilation and moduli F-terms. We further require Minimal String Unification, namely that large string threshold corrections ensure the correct unification of the gauge couplings at the grand unification scale. The whole supersymmetric mass spectrum turns out to be determined in terms of only two independent parameters, the dilaton-moduli mixing angle and the gravitino mass. In particular we discuss the region of the parameter space where at least one superpartner is ''visible'' at LEPII. We find that the most likely candidates are the scalar partner of the right-handed electron and the lightest chargino, with interesting correlations between their masses and with the mass of the lightest higgs. We show how discovering SUSY particles at LEPII might rather sharply discriminate between scenarios with pure dilaton SUSY breaking and mixed dilaton-moduli breaking. (author). 10 refs, 7 figs

    Thirty-five years after the Agency's founding, the IEA responsibility for ensuring access to global oil supplies is still a core mandate -- but new energy-related concerns have arisen. Energy security is no longer only about oil. And the industrialised nations of the world are no longer the only major consumers of energy. Climate change driven by greenhouse gas emissions -- 60% of which derive from energy production or use -- is a growing threat. So energy policy was tasked with a new objective: to cut greenhouse gas emissions while maintaining economic growth.

    Almost 40 years after the Agency’s founding, the IEA responsibility for ensuring access to global oil supplies is still a core mandate. Yet over the course of its history, the IEA’s responsibilities have expanded along with both the international energy economy and conceptions of energy security itself. Our mission to promote secure and sustainable energy provision spans the energy mix. At the same time, a changing global energy map means that the industrialised nations of the world no longer dominate energy consumption. The IEA must work in close co-operation with partner countries and organisations worldwide to achieve its three core objectives: energy security, economic prosperity, and environmental sustainability. Working toward international commitments to reduce greenhouse gas emissions that cause global climate change; facilitating energy technology exchange, innovation and deployment; improving modern energy access to the billions of people who are without it; bolstering both cleanliness and security through energy efficiency; and promoting flexible and functioning energy markets – these efforts complement our traditional core responsibilities of mitigating the effects of supply disruptions and improving statistical transparency.

    1978-10-01

    The 'soft energy path' concept derives from the sociopolitical sphere. The inclusion of the energy sector as an important part of our society is to prepare the technical side of this social change. The concept is clearly directed against nuclear power as the symbol of a centralized structure of energy, industry, population and power. However, the technical potential of soft energy technologies is incapable of keeping step with the qualitative and quantitative development of mankind and meeting the foreseeable energy requirement. The soft energy technologies are those alternative energy sources to substitute for oil and gas which require a maximum of capital investment. The soft energy approach demands that the industrialized countries reach zero energy growth as quickly as possible. But where is the capital to come from, if there is no more sufficient energy for production. If man, with his striving for welfare and his interest in self-expression, is really to be the center of these efforts, the soft energy approach and its claim of exclusivity must be expressed in a model which makes meaningful use of all technical possibilities.

    Ecologically neutral, cost efficient, without supply shortages, independent from foreign countries, risk- and waste-free - that is the image of an ideal future energy supply. But even if considerable ecological and economical improvements of various energy supply options can be achieved, the next generation of heat and power plants with the associated up- and down-stream parts of energy chains, will not comply with all such idealistic requirements. As research in the framework of the GaBE Project on 'Comprehensive Assessment of Energy Systems' has shown, among the reasons for this are the limited medium term potential of renewable energy sources, and the necessity to employ primarily non-renewable energy carriers for the emerging more efficient energy conversion processes.

    This paper proposes a novel energy management strategy for multi-cell high voltage batteries where the current through each cell can be controlled, called self-reconfigurable batteries. An optimized control strategy further enhances the energy efficiency gained by the hardware architecture of those batteries. Currently, achieving cell equalization by using the active balancing circuits is considered as the best way to optimize the energy efficiency of the battery pack. This study demonstrates that optimizing the energy efficiency of self-reconfigurable batteries is no more strongly correlated to the cell balancing. According to the features of this novel battery architecture, the energy management strategy is formulated as nonlinear dynamic optimization problem. To solve this optimal control, an optimization algorithm that generates the optimal discharge policy for a given driving cycle is developed based on dynamic programming and code vectorization. The simulation results show that the designed energy management strategy maximizes the system efficiency across the battery lifetime over conventional approaches. Furthermore, the present energy management strategy can be implemented online due to the reduced complexity of the optimization algorithm. - Highlights: • The energy efficiency of self-reconfigurable batteries is maximized. • The energy management strategy for the battery is formulated as optimal control problem. • Developing an optimization algorithm using dynamic programming techniques and code vectorization. • Simulation studies are conducted to validate the proposed optimal strategy.

    Regulation is the basic tool to implement energy policy. The evolution of the regulation is influenced by its impacts on the industrial activities. Consequently, entrepreneurs acts in a continuously adapting-by-interacting environment. Both from a systemic and an atomistic perspective, this paper provides a theoretical framework for energy regulation development in order to support management implications. This work builds on the triple helix model and extends it to energy regulation development processes. It concludes that the analysis of intangible resources and their related services at inter-organizational level is fundamental to guide companies in designing win-win corporate strategies and in their operazionalization.

    Energy internet is a new way of energy use. Energy internet achieves energy efficiency and low cost by scheduling a variety of different forms of energy. Particle Swarm Optimization (PSO) is an advanced algorithm with few parameters, high computational precision and fast convergence speed. By improving the parameters ω, c1 and c2, PSO can improve the convergence speed and calculation accuracy. The objective of optimizing model is lowest cost of fuel, which can meet the load of electricity, heat and cold after all the renewable energy is received. Due to the different energy structure and price in different regions, the optimization strategy needs to be determined according to the algorithm and model.

    An examination, for developed countries, of significant correlations among economic growth, electric energy intensity and elasticity, per capita values of gross national product and greenhouse gas emissions, indicates notable possibilities for a healthier global environment with increased world-wide diffusion of clean and rational energy use technologies coupled with substantial economic growth. This scenario, however, is contrasted by worrisome doubts as to the chances for a successful outcome of recently proposed tenable growth policies when it is pointed out that forecasts, based on current demographic trends, call for a doubling of the world population in the near future. The foreseen unrestrained population explosion, leading to an unprecedented proliferation in the use of fossil fuels, now appears to represent the most serious threat to the global environment

    This article synthesizes the main projection results for final use of energy consumed by residential sector on the next 20 years in Brazil, and evaluates their implications for a strategy of energetic sustainable development in Brazil. Arising out of previous studies performed for the Petroleum Brazilian Institute, for the Brazilian Ministry of Mines and Energy and for the IAEA, this article considers two sceneries: reference (REF) which considers significant changes, beyond those already consolidated; alternative (ALT), which considers progressive changes in the structure of residential sector (proportion of residences by income by revenue level and consumption), the energetic efficiency and a augmented participation of 'clean' energy sources. Both sceneries estimates potential growing of residences, gain of energetic efficiency, participation of commercial sources and use of natural gas in Brazil, and the rhythm of the implementation. The results show that the difference between the final use of energy by residential sector in REF (33.7 MtEP) in 2023 and in ALT (30.5 MtEP in 2023) can reach almost 10% during the next 20 years.

    In this paper, a control strategy is presented and numerically tested. This strategy aims to achieve the potential performance of fully active systems with a reduced energy supply. These energy needs are expected to be comparable to the power demands of semi-active systems, while system performance is intended to be comparable to that of a fully active configuration. The underlying strategy is called 'global semi-active control'. This control approach results from an energy investigation based on management of the optimal control process. Energy management encompasses storage and convenient restitution. The proposed strategy monitors a given active law without any external energy supply by considering purely dissipative and energy-demanding phases. Such a control law is offered here along with an analysis of its properties. A suboptimal form, well adapted for practical implementation steps, is also given. Moreover, a number of numerical experiments are proposed in order to validate test findings.

    To promote the development and application of renewable energy, under the planning and execution of Bureau of Energy of Ministry of Economical Affairs (BOEMOEA), Taiwan has implemented many measures for subsidizing the installation of RE apparatus since 2000. Besides subsidizing the installing expenses, Taiwanese government also provides incentive measures of finance/tax, such as investment deduction and accelerating depreciation. The successive growth of the amount of installing cases has apparently constructed the base of promotion and application of renewable energy; on the other hand, many barriers to be overcome were continuously discovered during the executing processes. To effectively remove these promoting barriers, the Energy Commission (the pre-BOE) issued 'Renewable Energy Development Plan' through the endorsement of Executive Yuan in January 2002. The purpose of this plan is to establish an inter-ministerial coordinating mechanism of a higher administrative level, which may focus all resources to be functioned as a working team. In the meantime, to further establish a systematically promoting mechanism, the Bureau of Energy then pushes the legislation of 'Renewable Energy Development Bill'. According to the drafted plan of this law, the power capacity of renewable energies will be 12% share of the national power installation capacity by 2020. Furthermore, in the Nuclear-free Homeland National Conference held in June 2003, government planned that the power capacity of renewable energy must reach 10% of the total power capacity in the nation by 2010. However, the share of the power capacity of renewable energy to the national power installation capacity is only 6.17%, currently, so there is still a lot of growing space for the development of renewable energy in Taiwan.

    Full Text Available n recent years, there has been considerable interest in the Arctic as a source for resources, as a potential zone for commercial shipping, and as a region that might experience conflict due to its strategic importance. With regards to energy resources, some studies suggest that the region contains upwards of 13 percent of global undiscovered oil, 30 percent of undiscovered gas, and multiples more of gas hydrates. The decreasing amount and duration of Arctic ice cover suggests that extraction of these resources will be increasingly commercially viable. Arctic and non-arctic states wish to benefit from the region's resources and the potential circum-polar navigation possibilities. This has led to concerns about the environmental risks of these operations as well as the fear that competition between states for resources might result in conflict. Unresolved offshore boundaries between the Arctic states exacerbate these fears. Yet, the risk of conflict seems overstated considering the bilateral and multilateral steps undertaken by the Arctic states to resolve contentious issues. This article will examine the potential impact of Arctic energy resources on global security as well as the regional environment and examine the actions of concerned states to promote their interests in the region.

    Bennigsen-Foerder, R. v.

    1982-01-01

    Energy utilities today are forced to live with the discrepancy between the wishes of the energy market and the wishes of politicians. This is the profound and real consequence of turning away from the market economy concept in energy supply, which has been observed increasingly since 1973/74. One major reason is the excessive emphasis on the continuity of supply, at the expense of economy, in the energy sector. This is understandable, of course, for the first oil crisis and the perception by society of the risks inherent in energy technologies have caused safety consciousness to grow. All this must be perceived against a background of a general move by society in favor of living in safety and without risk. This may explain why energy policy feels it has detected a need to act for the 'safety' goal. However, as far as striving for technical safety is concerned, the attitudes adopted by the German utilities under their own responsibility do not justify the existence of an individual government program. German industry unreservedly has always subscribed to the priority of safety in energy plants. No other point of view would be permissible in the light of its responsibility towards the public, but also towards its own personnel and the owners of the respective plants. (orig.) [de

The last politicians were guided, to favor the energy consumption with low prices of the coal, of the electricity, of those derived of the petroleum, growing subsidy to the gasoline and transfer of the productive sector toward the social one. In the recovery of the electric sector, it is contributed alternatives to improve the quality of the service of the electric industries where measured technical and investments in the industrial, commercial sectors and public would allow to reduce short term the consumptions for 5 to 10%, without reducing the production levels or of service. In the construction sector , the efficient designs of buildings could avoid a growth too much express of the energy consumption. The rational use of energy and the handling of the electric demand, should be one of the tools bigger than the State and of the electric industry, as the technical measures of reduction of losses, to respond to the financial crisis of the energy public sector, while the private sector acquires capacity of enough investment. The Colombians companies, experience the necessity to improve their energy efficiency, like one of the important areas of reduction of their costs and of increase of their competitiveness, in front of other countries, especially Latin-American. As consequence of the economic opening, the companies should modernize their processes and administration methods, what means a reduction in the energy consumptions.

    This study of competitiveness has three objectives. The first objective is to explain how macroeconomic and microeconomic factors can affect structural change in the US economy and how energy is linked to these factors. The second objective is to provide an explanation of how many individual decision makers, in responding to higher energy prices, have changed the structure of the economy. This structural change, and the effect it has had on energy use, is estimated for the US economy. A major component of these changes results from changes in US trade with other countries, which gives rise to the third objective. The third objective is to develop a research design that will allow a better understanding of the role that energy plays in the competitiveness of goods in world trade. 30 refs., 11 figs., 5 tabs.

    In February 1991, the Bush Administration released the National Energy Strategy designed to provide an adequate and balanced energy supply. The strategy provides for major increases in energy efficiency and conservation. Even with these savings, however, there will be a need for substantial increases in base-load electrical generating capacity to sustain economic growth. The strategy identifies the actions required to allow nuclear power to cleanly and safely meet a substantial portion of this needed additional base-load capacity after the turn of the century. On June 27, 1991, the US Department of Energy (DOE) transmitted to Congress the Strategic Plan for Civilian Reactor Development, which reflects the initiative identified in the National Energy Strategy. The strategic plan identifies the advanced light water reactor (ALWR) as the basis for expanded use of nuclear power. The second advanced reactor concept that is being pursued is the modular high-temperature gas-cooled reactor (MHTGR)

    The main objectives of this study are, first, to determine the sustainable energy strategies for green energy supply, and secondly, to derive the green energy recovery ratio and the sustainable green energy progress ratio, and thirdly, to investigate the effects of sustainable energy strategies on these ratios. For these purposes, 20-possible sustainable energy strategies are taken into consideration and are divided into three subgroups that are strategies on the technological impact, sectoral impact, and green energy impact in a society. Using the possible sustainable energy strategies, technological and sectoral impact ratios of green energy and also green energy activity ratio are determined and discussed in detail. Additionally, some Case studies are performed in the scope of this interesting investigation: (i) the effect of technological impact ratio on green energy recovery ratio, and sustainable green energy progress ratio, (ii) the effect of sectoral impact ratio on green energy recovery ratio, and sustainable green energy progress ratio, and (iii) the effect of green energy impact ratio on green energy recovery ratio and sustainable green energy progress ratio. It is found that sustainable green energy progress ratio increases with an increase of technological, sectoral, and green energy impact ratios. This means that all negative effects on the industrial, technological, sectoral and social developments partially and/or completely decrease throughout the transition and utilization to and of green energy and technologies when possible sustainable energy strategies are preferred and applied. Thus, the sustainable energy strategies can make an important contribution to the economies of the countries where green energy is abundantly produced. Therefore, the investment in green energy supply should be, for the future of world nations, encouraged by governments and other authoritative bodies who, for strategic reasons, wish to have a green alternative to fossil

    The energy supply optimization model MESSAGE-III is improved to evaluate the role of nuclear energy system in Korean long-term energy supply strategy. Emphasis is placed on the potential contribution of nuclear energy in case of environmental constraints and energy resource limitation. The time horizon is 1993-2040. A program to forecast useful energy demand is developed, and optimization is performed from the overall energy system to the nuclear energy system. Reactor and fuel cycle strategy and the expanded utilization options for nuclear energy system are suggested. FBRs, HTGRs and thorium fuel cycle would play key roles in the long run. The most important factors for nuclear energy in Korean energy supply strategy would be the availability of fossil fuels, CO 2 reduction regulation, and the supply capability of nuclear energy.

  16. A Mixed Transmission Strategy to Achieve Energy Balancing in Wireless Sensor Networks

    DEFF Research Database (Denmark)

    Liu, Tong; Gu, Tao; Jin, Ning

    2017-01-01

    In this paper, we investigate the problem of energy balanced data collection in wireless sensor networks, aiming to balance energy consumption among all sensor nodes during the data propagation process. Energy balanced data collection can potentially save energy consumption and prolong network...... lifetime, and hence, it has many practical implications for sensor network design and deployment. The traditional hop-by-hop transmission model allows a sensor node to propagate its packets in a hop-by-hop manner toward the sink, resulting in poor energy balancing for the entire network. To address...... the problem, we apply a slice-based energy model, and divide the problem into inter-slice and intra-slice energy balancing problems. We then propose a probability-based strategy named inter-slice mixed transmission protocol and an intra-slice forwarding technique to address each of the problems. We propose...

    This paper examines the mutual implications between the climate change problem and the actual energy-at-a-crossroads situation of the unsustainable world energy model. The implications for the Spanish case are studied as a case example. The paper provides a brief review of the scientific evidence on climate change, analyzes the causes of the present energy dilemma and characterizes the problem to be addressed. The principal challenge for the future climate regime is to identify the nature and level of commitment that will provide sufficient incentives for all countries, with such a diversity of interests. The paper also exposes the most plausible framework for the future climate regime, the basic components of such a regime, the role to be played by the major stake holders and some guidelines for future negotiations.

    Full Text Available The article is devoted to the transformation of the energy strategy of Russia in the conditions of the current economic crisis. The special attention is paid to current trends in the sphere of international relations having a decisive influence on the formation of Russia’s energy strategy. The authors point to the crisis of the modern world, the deepening of interstate contradictions, the expansion of confrontation, the revision of the uniform principles of trade, established by the World Trade Organization, the changes in the global financial system. The authors investigate the possibility of political arrangements between the leading suppliers of oil on the destabilization of the oil market in order to achieve geopolitical goals. In the article special attention is also paid to the issue of political motivation of anti-Russian sanctions directed at impeding Russia’s development and its Fuel & Energy Complex, in particular. Today, against the background of the current political situation, the energy strategy of Russia is exposed to adjustment. The country has the important task of ensuring technological independence of the energy sector on the basis of import substitution of the equipment, diversification of the directions of export of energy resources, preservation of leading positions in the world market of peaceful nuclear energy, etc. The authors conclude that the energy strategy of Russia is important part of foreign policy strategy of the country, and it is focused on practical cooperation with all countries and is aimed at protecting interests of the state.

    This report provides a framework for understanding the practical implications of consumer energy conservation research in Canada. A review of such research was undertaken to determine its implications for increasing the effectiveness of Canadian conservation policies and programs. The major conclusions and recommendations were as follows. Conservation has been acknowledged as the single most important element in solving Canada's petroleum shortfall in the 1980s. An analytic approach to the formulation of energy policies and the design of conservation programs will be essential if meaningful energy savings in the consumer sector are to be realized. Prior to designing any conservation program, it is essential that the components of consumer energy policy be understood. In order to assess the effectiveness of conservation efforts, it is necessary to assign relative priorities to the criteria of probable energy savings, cost effectiveness, impact by fuel type, impact on consumers, enforceability, and institutional considerations. Conservation efforts aimed at consumers must be based on understanding the basic processes which underlie how they perceive and respond to various types of conservation initiatives. This understanding is gained through consumer impact analysis and program research. The latter action attempts to analyze the effectiveness and acceptability of programs involving information, financial incentives, energy standards, and energy usage restrictions. Conservation programs must ensure that barriers to adoption, such as lack of time and knowledge, financial resources, and lifestyle impacts, will be minimized. 93 refs., 3 figs., 13 tabs.

    Cooperation between public and private sector has achieved a remarkable widespread, in the Italian context, over the last two decades. Nevertheless, the increasing difficulty in accessing the capital market and the rising cost of funding sources, both noticeable over the past few years, led to a slowdown of Public–Private Partnership (PPP) initiatives. Meanwhile, the community is expressing new needs to be satisfied, such as the conversion of brownfields, the recovery of housing stock dating back to former times, as well as the refurbishment of public offices or schools. Emerging priorities include the supply of affordable dwellings for low to medium income households. This essay aims to examine a case study in which PPP and buildings energy efficiency have been successfully combined, in order to jointly contribute to the achievement of a social housing settlement. Thanks to energy efficiency measures—concerning building envelope insulation, heating system and other installations—the agreed rent results far higher than social rent of protected tenancies, and furthermore above the range of fair rents characterising other regulated tenancies, but mildly lower than market rents. All this allows to achieve an equity yield rate satisfying from the perspective of a venture philanthropy investment. -- Highlights: •Provision of affordable dwellings is an emerging priority within Italian context. •Lack of public funds leads to promote Public–Private Partnership schemes. •Without public grants the adoption of a venture philanthropy approach is needed. •The examined case study allows to explain the role of buildings energy efficiency. •Buildings energy efficiency may boost feasibility of social housing transactions

    UK Energy Policy is leading the world in showing how governments can effectively respond to the now widely accepted challenges of security of supply, low-carbon generation and pragmatic implementation. Confidence in the UK as place to invest in new nuclear is very high-there are already 3 developers who have between them already invested over 1 billion, 5 sites are planned to be developed and between 10 and 12 new reactors are planned to be built. To be clear, this is by far the largest commitment to new nuclear in the Western World and swamps in other countries. This achievement is a combination of vision, continuity, political consensus and a group of ministers and officials who are clear in the goals for the long-term sustain ability of an energy policy that will dramatically affect the lives of many generations to come. Recognising the multi-generational obligations and consequences of government policy's key to ensuring that this investment continues, together with the maintenance of the trust that investors have developed in the management of energy policy by the UK government. There is no doubt in the commitment of the UK government to delivering the safe, secure and low-carbon energy future of the UK. The opportunities for businesses and high-quality job creation are undoubted-all that now has to happen is for developers, reactor vendors, construction companies and communities to show how they can together deliver the cheapest form of low-carbon base load to time and to cost and to the benefit of local communities and the UK economy. the world is watching for the UK to show how it can be done.

    A referendum was held in Sweden on 23rd March 1980, stimulated by the Three Mile Island accident in USA, to determine the future nuclear power development policy. The electricity supply background is that in 1980, 65% of power was hydro, 25% nuclear and 10% coal and oil. In terms of total power consumption, the country is heavily dependent on oil, which represents about 75%. The intensive public relations activity previous to the referendum is described, and this involved fact accumulation and assimilation, dissemination through various media, including brochures, displays, films and leaflets. In the political arena three lines developed: (1) (Conservatives); continue nuclear power, building at least 12 reactors, (2) (Social democrats and liberals); similar to (1), but more cautious, with emphasis on energy conservation, (3) (Centre parties and communists); no more nuclear power, and prevention of uranium extraction in Sweden.

    Chae, Kyu Nam

    1995-02-01

    An energy demand and supply analysis is carried out to establish the future nuclear energy system of Korea in the situation of environmental restriction and resource depletion. Based on the useful energy intensity concept, a long-term energy demand forecasting model FIN2USE is developed to integrate with a supply model. The energy supply optimization model MESSAGE is improved to evaluate the role of nuclear energy system in Korean long-term energy supply strategy. Long-term demand for useful energy used as an exogeneous input of the energy supply model is derived from the trend of useful energy intensity by sectors and energy carriers. Supply-side optimization is performed for the overall energy system linked with the reactor and nuclear fuel cycle strategy. The limitation of fossil fuel resources and the CO 2 emission constraints are reflected as determinants of the future energy system. As a result of optimization of energy system using linear programming with the objective of total discounted system cost, the optimal energy system is obtained with detailed results on the nuclear sector for various scenarios. It is shown that the relative importance of nuclear energy would increase especially in the cases of CO 2 emission constraint. It is concluded that nuclear reactor strategy and fuel cycle strategy should be incorporated with national energy strategy and be changed according to environmental restriction and energy demand scenarios. It is shown that this modelling approach is suitable for a decision support system of nuclear energy policy

    Heavy water plant at Manuguru is designed to produce 185 MTY of NG heavy water based on bi-thermal H 2 S-H 2 O exchange process. Being a plant based on isotopic separation process, the requirement of feed water, utilities and the inventory of H 2 S is very huge. Sustained efforts have brought down the specific energy consumption from 53.3 GJ/Kg of nuclear grade product in the financial year 1997-98 to a value of 37.6 GJ/Kg of product in the financial year 2001-02, which amounts to a reduction of 29.5%. Several modifications have been done in the following areas, which contributed towards significant energy conservation eg. reduction in consumption of steam, electric power, chemicals and man hours and in the down time of the plant/equipment's, reduction in the loss of H 2 S, D 2 O and various utilities, enhanced recycling of liquid effluents, increase in production, on stream hours, purity of the inputs, avoiding trips and unusual occurrences, trimming the built in cushions, changes in the design/elimination of certain design provisions resulting in savings, increase in operational flexibility to facilitate smooth operation, improved house keeping and quality management, improved O and M practices, upgradation of required skills/qualifications of the personnel and increasing their motivation.

    This study develops estimates of energy use and recovery from managing municipal solid waste (MSW) under various collection, processing, and disposal scenarios. We estimate use and recovery -- or energy balance -- resulting from MSW management activities such as waste collection, transport, processing, and disposal, as well as indirect use and recovery linked to secondary materials manufacturing using recycled materials. In our analysis, secondary materials manufacturing displaces virgin materials manufacturing for 13 representative products. Energy implications are expressed as coefficients that measure the net energy saving (or use) of displacing products made from virgin versus recycled materials. Using data developed for the 1992 New York City Master Plan as a starting point, we apply our method to an analysis of various collection systems and 30 types of facilities to illustrate bow energy balances shift as management systems are modified. In sum, all four scenarios show a positive energy balance indicating the energy and advantage of integrated systems versus reliance on one or few technology options. That is, energy produced or saved exceeds the energy used to operate the solid waste system. The largest energy use impacts are attributable to processing, including materials separation and composting. Collection and transportation energy are relatively minor contributors. The largest two contributors to net energy savings are waste combustion and energy saved by processing recycled versus virgin materials. An accompanying spatial analysis methodology allocates energy use and recovery to New York City, New York State outside the city, the U.S., and outside the U.S. Our analytical approach is embodied in a spreadsheet model that can be used by energy and solid waste analysts to estimate impacts of management scenarios at the state and substate level.

    A model of the world energy market that incorporates price expectations and lagged adjustments of demand and supply is used to examine implications of various price-paths that could be selected by OPEC. After demonstrating the sensitivity of the results to changes in functional specifications and certain parameter values, the authors discuss a variety of rule-of-thumb pricing strategies under which OPEC sets prices in response to available market signals. A strategy that is relatively cautious about further major price increases serves OPEC relatively well in comparison with other stategies, but there exists a real possibility of major, abrupt price increases within the next ten years.

    Water and wastewater systems are significant energy consumers with an estimated 3%-4% of total U.S. electricity consumption used for the movement and treatment of water and wastewater. Water-energy issues are of growing importance in the context of water shortages, higher energy and material costs, and a changing climate. In this economic environment, it is in the best interest for utilities to find efficiencies, both in water and energy use. Performing energy audits at water and wastewater treatment facilities is one way community energy managers can identify opportunities to save money, energy, and water. In this paper the importance of energy use in wastewater facilities is illustrated by a case study of a process energy audit performed for Crested Butte, Colorado's wastewater treatment plant. The energy audit identified opportunities for significant energy savings by looking at power intensive unit processes such as influent pumping, aeration, ultraviolet disinfection, and solids handling. This case study presents best practices that can be readily adopted by facility managers in their pursuit of energy and financial savings in water and wastewater treatment. This paper is intended to improve community energy managers understanding of the role that the water and wastewater sector plays in a community's total energy consumption. The energy efficiency strategies described provide information on energy savings opportunities, which can be used as a basis for discussing energy management goals with water and wastewater treatment facility managers.

    It should be recognized that the key to the future is in the rational use of energy, that is, a more efficient use of energy rather than a continuous increase in the supply of energy. Every unit of energy saved is a unit of energy which does not have to be produced, and whose environmental impacts do not have to be dealt with. Massive reductions in the growth rates, and, where possible, in the absolute use of energy will help us to gain time to better understand and develop response strategies to problems like climate change on the acidification of the environment. In this sense the rational use of energy, including intensified energy efficiency measures is the most environmentally sound energy option with which we should move into the next century. 25 refs., 4 figs

  7. The energy situation and its sustainable development strategy in China

    Zhang, Na; Lior, Noam; Jin, Hongguang

    2011-01-01

    The paper briefly summarizes China's energy situation and sustainable development strategy as they were by 2009. The energy consumption in 2009 is reported to be 3.1 billion tons standard coal equivalent, 1/7 of the world total, 6.3% higher than in the year 2008, and its share of world CO 2 emissions increased rapidly to 20.3% in 2006. These trends are most likely to continue with China's plan to accomplish its social and economy development goals. To address these problems and also respond to increasing world pressure for reduction of greenhouse gas emissions, the Chinese government plans and has legislated promotion of energy conservation, efficiency, renewable energy technologies and use, and reduction of energy-related environmental impacts to reduce energy intensity by 20% during the 2006-2010 period, and to reduce the CO 2 emission/GDP ratio by 40-45% by 2020 relative to 2005. China is facing severe energy-related challenges that conflict resources shortages with the planned rapid economic development, energy use with the related environmental pollution, and new technology with the old production/consumption patterns. It is recognized that energy development must, however, follow a sustainable path to coordinate economy growth, social development, and environmental protection. -- Highlights: → A brief summary of China's energy situation and plans in 2009; → Energy consumption and CO 2 emissions are likely to continue rising; → China to reduce energy intensity, and the (CO 2 emission)/GDP ratio by 40-45% by 2020; → Energy-related challenges and desired sustainable development strategy are discussed; → The strategy core is energy conservation and non-fossil fuel energy development.

  8. Energy scope of handoff strategies in macro-femtocell environments

    Energy consumption in downlink mode is becoming an important topic as cellular communications grow into a large scale enterprise. The search for high rates keeping energy constraints low has put forward the idea that cells with smaller size may improve not only the capacity of the network, but also reduce the amount of energy that is needed to achieve such capacities. When using heterogeneous networks, users can be encouraged to handoff to a femtocell, that offers better capacity per unit energy spent, by means of different handoff strategies. These strategies may also improve the energy use of the network if the handoff priority is given to both, capacity, and energy use. © 2012 IEEE.

  9. Getting to Grips Again with Dependency. Japan's Energy Strategy

    Japan has had to deal with a high level of dependency on energy imports for many decades. Today the country faces an increasingly competitive global energy market that forces it to reinvent its traditional security of supply policies. Unfortunately for Japan, the rise of China and India is increasing the competition for scarce energy supplies among consumer countries, whereas in the past supplier countries competed for access to the attractive Japanese market. To confront the challenges of the new environment the Japanese government has drafted a New National Energy Strategy. This paper analyses the strength of the strategy's proposals and targets, in particular those aimed at improving security of oil and gas supply. To assess the impact of the strategy we place it firmly against the background of Japan's history of energy security policy, as well as Japan's recent experiences with 'strategic resource projects'. This paper finds that Japan's policies in post-1973 history have been impeded by a complex set of factors. Traditionally this set has included Japan's troubled bilateral relations with Russia and China, and Japan's security dependence on the United States. Other factors are Japan's inability to synchronise national and corporate interests, and a lack of cooperation between domestic energy companies. More recently, rising oil prices, growing resource competition with China and lacklustre domestic demand-growth for energy have increased anxiety about security of supply amongst policymakers in Tokyo. In three case studies the paper illustrates in detail how these factors - in combination or by themselves - have structurally compromised Japanese initiatives to improve security of supply. The case studies discuss the Azadegan oil development project in Iran, plans for a pan-Siberian oil pipeline, and the oil and gas projects on Russia's Sakhalin Island. Our analysis of the New National Energy Strategy confirms that energy security is back on Japan's policy

    The inherent limitation in performance of building envelop components and heating ventilating and air conditioning (HVAC) equipment necessitates the examination of operational strategies for improvement in energy-efficient operation of buildings. Due to the ease of installation and increasing availability of electronic controllers, operational strategies that could be programmed are of particular interest. The Iowa Energy Center in the US has taken the initiative to conduct the necessary assessment of current HVAC technology and the commonly-used operational strategies for commercial and industrial buildings, as applied to the midwestern part of the country, with weather and energy cost data for Des Moines, Iowa. The first part of this study focused on the energy consumption and cost effectiveness of HVAC systems. The objectives of the second part is concerned with examination of various operational strategies, namely, night purge (NP), fan optimum start and stop (OSS), condenser water reset (CWR), and chilled water reset (CHWR) applied to order and newer-type commercial office buildings. The indoor air quality requirement are met and the latest applicable energy rates from local utility companies are used. The results show that, in general, NP is not an effective strategy in buildings with low thermal mass storage, OSS reduced fan energy, and CWR and CHWR could be effective and require chillers with multi-stage unloading characteristics. The most operationally efficient strategies are the combination of OSS, CWR, and CHWR for the older-type building, and OSS for the newer-type building. Economically, the most effective is the OSS strategy for the older-type building and the CHWR strategy for the newer-type building.(Author)

    the onset of spawning. Female weight explained 84% of the observed variance for fecundity. The gonadosomatic, hepatosomatic and condition indexes varied significantly with the reproductive season for females and only the gonadosomatic index for males. Storage in muscle seemed to be the primary source of energy for reproduction, although liver appeared to play a short-term role in egg production, suggesting a combination of capital and income breeding. The results indicate that the life history strategy of common dentex possess consist on maturing well before reaching maximum size, investing in growth after maturation, and therefore the reproductive effort is distributed through a longer lifespan and related with the size attained after maturation. At present no management measures are directed to D. dentex; given its life history strategy we suggest that a slot limit should be implemented, i.e. a minimum and a maximum landing size, with a minimum size of 35 cm. The upper threshold, to protect the higher reproductive potential of older and larger fish, should still be defined.

    Yang, Liu; Yan, Haiyan; Lam, Joseph C.

    2014-01-01

    Highlights: • We review studies of thermal comfort and discuss building energy use implications. • Adaptive comfort models tend to have a wider comfort temperature range. • Higher indoor temperatures would lead to fewer cooling systems and less energy use. • Socio-economic study and post-occupancy evaluation of built environment is desirable. • Important to consider future climate scenarios in heating, cooling and power schemes. - Abstract: Buildings account for about 40% of the global energy consumption and contribute over 30% of the CO 2 emissions. A large proportion of this energy is used for thermal comfort in buildings. This paper reviews thermal comfort research work and discusses the implications for building energy efficiency. Predicted mean vote works well in air-conditioned spaces but not naturally ventilated buildings, whereas adaptive models tend to have a broader comfort temperature ranges. Higher indoor temperatures in summertime conditions would lead to less prevalence of cooling systems as well as less cooling requirements. Raising summer set point temperature has good energy saving potential, in that it can be applied to both new and existing buildings. Further research and development work conducive to a better understanding of thermal comfort and energy conservation in buildings have been identified and discussed. These include (i) social-economic and cultural studies in general and post-occupancy evaluation of the built environment and the corresponding energy use in particular, and (ii) consideration of future climate scenarios in the analysis of co- and tri-generation schemes for HVAC applications, fuel mix and the associated energy planning/distribution systems in response to the expected changes in heating and cooling requirements due to climate change

    The energy requirements of many novel protein production systems are compared with an examination of the relevant environmental implications of these systems. The prospects for single cell protein, leaf protein, fish farming, fish protein concentrate, algal cultivation, and hydroponic plant growth systems are investigated. Single cell protein from carbohydrate substrates, algal protein, and fish protein seem to hold much promise, as they are technologically feasible for near-term implementation and do not require major energy inputs.

    This study evaluates the energy, humidity and indoor air quality (IAQ) implications of residential ventilation cooling in all U.S. IECC climate zones. A computer modeling approach was adopted, using an advanced residential building simulation tool with airflow, energy and humidity models. An economizer (large supply fan) was simulated to provide ventilation cooling while outdoor air temperatures were lower than indoor air temperatures (typically at night). The simulations were performed for a full year using one-minute time steps to allow for scheduling of ventilation systems and to account for interactions between ventilation and heating/cooling systems.

    1981-01-01

    A referendum was held in Sweden on 23rd March 1980, stimulated by the Three Mile Island accident in USA, to determine the future nuclear power development policy. The electricity supply background is that in 1980, 65% of power was hydro, 25% nuclear and 10% coal and oil. In terms of total power consumption, the country is heavily dependent on oil, which represents about 75%. The intensive public relations activity previous to the referendum is described, and this involved fact accumulation and assimilation, dissemination through various media, including brochures, displays, films and leaflets. In the political arena three lines developed: (1) (Conservatives); continue nuclear power, building at least 12 reactors, (2) (Social democrats and liberals); similar to (1), but more cautious, with emphasis on energy conservation, (3) (Centre parties and communists); no more nuclear power, and prevention of uranium extraction in Sweden. The voting was (1) 18.9%, (2) 39.1%, (3) 38.7%, (No decision) 3.3%. (G.C.)

    The main EU programmes, supporting the renewable deployment, are the research and development programmes JOULE, THERMIE and FAIR, included in the 4th framework programme, the ALTENER programme and the `Community Support Framework` programme. Research and development (R and E) activity within the JOULE and THERMIE programmes are divided into five areas, of which the third concerns the renewable energies. The support could range from 40 to 100 % of the cost. JOULE programme is research oriented, while the THERMIE programme is demonstration oriented. The FAIR programme is also a specific research and development programme for agriculture and agrifood industry. It could cover, among others, projects in connection with the biogas exploitation. The ALTENER programme provides support for the so called `software` actions, promoting renewables, mainly training and information actions, including events like the present one. Furthermode, it provides support for technical specifications, creation of infrastructure for the promotion of renewables and so on. ALTENER does not support investments. Finally the `Community Support Framework` programme promoting the regional development, could, in some cases, support traditional technology investments in relation to renewables. (au)

  19. Methodological differences behind energy statistics for steel production – Implications when monitoring energy efficiency

    International Nuclear Information System (INIS)

    Morfeldt, Johannes; Silveira, Semida

    2014-01-01

    Energy efficiency indicators used for evaluating industrial activities at the national level are often based on statistics reported in international databases. In the case of the Swedish iron and steel sector, energy consumption statistics published by Odyssee, Eurostat, the IEA (International Energy Agency), and the United Nations differ, resulting in diverging energy efficiency indicators. For certain years, the specific energy consumption for steel is twice as high if based on Odyssee statistics instead of statistics from the IEA. The analysis revealed that the assumptions behind the allocation of coal and coke used in blast furnaces as energy consumption or energy transformation are the major cause for these differences. Furthermore, the differences are also related to errors in the statistical data resulting from two different surveys that support the data. The allocation of coal and coke has implications when promoting resource as well as energy efficiency at the systems level. Eurostat's definition of energy consumption is more robust compared to the definitions proposed by other organisations. Nevertheless, additional data and improved energy efficiency indicators are needed to fully monitor the iron and steel sector's energy system and promote improvements towards a greener economy at large. - Highlights: • Energy statistics for the iron and steel sector diverge in international databases. • Varying methods have implications when monitoring energy and resource efficiency. • Allocation of blast furnaces as transformation activities is behind the differences. • Different statistical surveys and human error also contribute to diverging results

    Full Text Available Under the global voice of “energy saving” and the current boom in the development of energy storage technology at home and abroad, energy optimal control of the whole hybrid electric vehicle power system, as one of the core technologies of electric vehicles, is bound to become a hot target of “clean energy” vehicle development and research. This paper considers the constraints to the performance of energy storage system in Parallel Hybrid Electric Vehicle (PHEV, from which lithium-ion battery frequently charges/discharges, PHEV largely consumes energy of fuel, and their are difficulty in energy recovery and other issues in a single cycle; the research uses lithium-ion battery combined with super-capacitor (SC, which is hybrid energy storage system (Li-SC HESS, working together with internal combustion engine (ICE to drive PHEV. Combined with PSO-PI controller and Li-SC HESS internal power limited management approach, the research proposes the PHEV energy optimal control strategy. It is based on revised Pontryagin’s minimum principle (PMP algorithm, which establishes the PHEV vehicle simulation model through ADVISOR software and verifies the effectiveness and feasibility. Finally, the results show that the energy optimization control strategy can improve the instantaneity of tracking PHEV minimum fuel consumption track, implement energy saving, and prolong the life of lithium-ion batteries and thereby can improve hybrid energy storage system performance.

    2010-01-01

    Economic assessments of the welfare effects of energy insecurity are typically uncertain and fail to provide clear guidance to policy makers. As a result, governments have had little analytical support to complement expert judgment in the assessment of energy security. This is likely to be inadequate when considering multiple policy goals, and in particular the intersections between energy security and climate change mitigation policies. This paper presents an alternative approach which focuses on gauging the causes of energy insecurity as a way to assist policy making. The paper focuses on the energy security implications of fossil fuel resource concentration and distinguishes between the price and physical availability components of energy insecurity. It defines two separate indexes: the energy security price index (ESPI), based on the measure of market concentration in competitive fossil fuel markets, and the energy security physical availability index (ESPAI), based on the measure of supply flexibility in regulated markets. The paper illustrates the application of ESPI and ESPAI with two case studies-France and the United Kingdom-looking at the evolution of both indexes to 2030.

    This report has been prepared by the Energy Information Administration at the request of the Department of Energy's Office of Policy, Planning and Analysis. The results are based on assumptions provided by the Department of Energy's Office of Conservation and Renewable Energy, the Office of Nuclear Energy, the Office of Fossil Energy, and the Office of Policy, Planning and Analysis. This report serves as an auxiliary document to the publication, Improving Technology: Modeling Energy Futures for the National Energy Strategy, prepared by the Energy Information Administration (EIA), to be used as input to the development of a National Energy Strategy. The excursions discussed in this report are not necessarily the policy options which will be selected for inclusion in the National Energy Strategy (NES). This report examines the effects of various supply side options for electric utilities. The three excursions presented are: (1) Effects of the Clean Air Act Amendments on Reducing SO 2 /NO x Emissions which evaluates the impacts of proposed legislation to amend the Clean Air Act (Title V of H.R. 3030 as amended on May 23, 1990); (2) Nuclear Life Extension/New Nuclear Orders which illustrates the impact of new nuclear power plant orders and the life extension of existing nuclear plants; and (3) Nuclear and Accelerated Fossil-Fueled Generating Technologies which portrays accelerated research and development of advanced fossil-fueled generating technologies, making them commercially available earlier, with the inclusion of the nuclear option. The baseline case of this report is an update and an extension of the base case projections in the Energy Information Administration (EIA) publication, the Annual Energy Outlook 1990 (AEO), extending that forecast an additional 20 years to 2030. It represents the baseline case as it was on July 1990. 29 refs., 9 figs., 19 tabs. (JF)

    Full Text Available This study examines the impacts of matching competitive environment, business strategy, and corporate governance structure on firm performance. We predict that in a dynamic environment, firms pursuing a product differentiation strategy will perform better than firms pursuing a strategy of cost leadership, but the performance differential is affected by the level of board independence and managerial share ownership. In a stable environment, we predict that firms pursuing a strategy of cost leadership will perform better than firms pursuing a product differentiation strategy, and the performance differential is affected by the level of board independence and managerial share ownership. Overall, the results are consistent with the predictions of this study. Board independence and managerial ownership affect the performance differential between product differentiators and cost leaders in a dynamic environment. In a stable environment, however, the results are not statistically significant.

  9. Dispatch Strategy Development for Grid-tied Household Energy Systems

    Science.gov (United States)

    Cardwell, Joseph

    The prevalence of renewable generation will increase in the next several decades and offset conventional generation more and more. Yet this increase is not coming without challenges. Solar, wind, and even some water resources are intermittent and unpredictable, and thereby create scheduling challenges due to their inherent "uncontrolled" nature. To effectively manage these distributed renewable assets, new control algorithms must be developed for applications including energy management, bridge power, and system stability. This can be completed through a centralized control center though efforts are being made to parallel the control architecture with the organization of the renewable assets themselves--namely, distributed controls. Building energy management systems are being employed to control localized energy generation, storage, and use to reduce disruption on the net utility load. One such example is VOLTTRONTM, an agent-based platform for building energy control in real time. In this thesis, algorithms developed in VOLTTRON simulate a home energy management system that consists of a solar PV array, a lithium-ion battery bank, and the grid. Dispatch strategies are implemented to reduce energy charges from overall consumption (/kWh) and demand charges (/kW). Dispatch strategies for implementing storage devices are tuned on a month-to-month basis to provide a meaningful economic advantage under simulated scenarios to explore algorithm sensitivity to changing external factors. VOLTTRON agents provide automated real-time optimization of dispatch strategies to efficiently manage energy supply and demand, lower consumer costs associated with energy usage, and reduce load on the utility grid.

    1991-02-01

    The National Energy Strategy lays the foundation for a more efficient, less vulnerable, and environmentally sustainable energy future. It defines international, commercial, regulatory, and technological policy tools that will substantially diversify US sources of energy supplies and offer more flexibility and efficiency in the way energy is transformed and used. Specifically, it will spur more efficiency and competition throughout the energy sector, expand the fuel and technology choices available to the Nation, improve US research and development (R ampersand D), and support the international leadership the United States exercises in energy, economic, security, and environmental policy. The Strategy builds upon a number of Bush Administration initiatives. These include the following: (1) the 1990 revisions to the Clean Air Act; (2) natural gas wellhead decontrol legislation in 1989; (3) incentives provided to domestic renewable and fossil energy producers in the fiscal year 1991 budget agreement; (4) the uprecedented international consensus forged in the wake of the Persian Gulf crisis; (5) the fiscal year 1991 and 1992 realignments of the Department of Energy's research and program priorities; (6) the Administration's domestic energy supply and demand measures adopted in response to the Iraqi oil disruption; and (7) the science and mathematics education initiatives by the Secretary of Energy

    Highlights: • Various strategies for HVAC energy saving are described and reviewed. • The influence of each strategy on the HVAC energy saving is investigated. • Combination of existing air conditioning technologies appears to be effective for the energy conservation and comfort. • A comparison study between these approaches is carried out. • Changing the HVAC configuration has the potential to increase or reduce energy savings, depending on several factors. - Abstract: Decreasing the energy consumption of heating, ventilation and air conditioning (HVAC) systems is becoming increasingly important due to rising cost of fossil fuels and environmental concerns. Therefore, finding novel ways to reduce energy consumption in buildings without compromising comfort and indoor air quality is an ongoing research challenge. One proven way of achieving energy efficiency in HVAC systems is to design systems that use novel configurations of existing system components. Each HVAC discipline has specific design requirements and each presents opportunities for energy savings. Energy efficient HVAC systems can be created by re-configuring traditional systems to make more strategic use of existing system parts. Recent research has demonstrated that a combination of existing air conditioning technologies can offer effective solutions for energy conservation and thermal comfort. This paper investigates and reviews the different technologies and approaches, and demonstrates their ability to improve the performance of HVAC systems in order to reduce energy consumption. For each strategy, a brief description is first presented and then by reviewing the previous studies, the influence of that method on the HVAC energy saving is investigated. Finally, a comparison study between these approaches is carried out

    Indonesia as an emerging country with one of the fastest growing economies requires sufficient supply with energy for national development. Domestic energy production cannot satisfy the domestic demand, and the deficiency necessitates growing imports. The present energy mix consists of 96% from non-renewable sources, i.e. fossil fuels, less than 4% from renewables. Government Regulation 5/2006 aims at increasing the proportion of renewable sources to 17%. Two scenarios for the energy situation in 2025 have been elaborated and are discussed. An overall energy policy strategy and regulatory framework covering non-renewable and renewable resources are crucial for securing energy demand. - Highlights: • Indonesia aims at 17% renewable energy in energy mix 2025. • Population growth exceeds increase of energy production. • Investment incentives for new technologies, exploration and efficient production are necessary. • Clear and comprehensive energy policy strategy and regulatory framework are crucial

    Full Text Available With energy security, climate change mitigation, and sustainable development as three main motives, global energy policies have evolved, now asking for higher shares of renewable energies, shale oil and gas resources in the global energy supply portfolios. Yet, concerns have recently been raised about the environmental impacts of the renewable energy development, supported by many governments around the world. For example, governmental ethanol subsidies and mandates in the U.S. are aimed to increase the biofuel supply while the water footprint of this type of energy might be 70–400 times higher than the water footprint of conventional fossil energy sources. Hydrofracking, as another example, has been recognized as a high water-intensive procedure that impacts the surface and ground water in both quality and quantity. Hence, monitoring the water footprint of the energy mix is significantly important and could have implications for energy policy development. This paper estimates the water footprint of current and projected global energy policies, based on the energy production and consumption scenarios, developed by the International Energy Outlook of the U.S. Energy Information Administration. The outcomes reveal the amount of water required for total energy production in the world will increase by 37%–66% during the next two decades, requiring extensive improvements in water use efficiency of the existing energy production technologies, especially renewables.

    The policy instruments considered include: greater reliance on market forces; research and development; information, education and demonstration programs; tax incentives and sanctions; mortgage and finance programs; and regulations and standards. The analysis starts with an explanation of the barriers to energy conservation in the residential and commercial sectors. Individual policy instruments are described and evaluated with respect to energy conservation, economic efficiency, equity, political impacts, and implementation and other transitional impacts. Five possible strategies are identified: (1) increased reliance on the market place; (2) energy consumption tax and supply subsidies; (3) Building Energy Performance Standards (BEPS) with no sanctions and no incentives; (4) BEPS with sanctions and incentives (price control); and (5) BEPS with sanctions and incentives (no price controls). A comparative analysis is performed. Elements are proposed for inclusion in a comprehensive strategy for conservation in new buildings.

    2012-07-01

    Full Text Available In this paper, an energy storage system with voltage equalization strategy for wind energy conversion is presented. The proposed energy storage system provides a voltage equalization strategy for series-connected lead-acid batteries to increase their total storage capacity and lifecycle. In order to draw the maximum power from the wind energy, a perturbation-and-observation method and digital signal processor (DSP are incorporated to implement maximum power point tracking (MPPT algorithm and power regulating scheme. In the proposed energy storage system, all power switches have zero-voltage-switching (ZVS feature at turn-on transition. Therefore, the conversion efficiency can be increased. Finally, a prototype energy storage system for wind energy conversion is built and implemented. Experimental results have verified the performance and feasibility of the proposed energy storage system for wind energy conversion.

  1. Public sector energy management: A strategy for catalyzing energy efficiency in Malaysia

    Science.gov (United States)

    Roy, Anish Kumar

    To date the public sector role in facilitating the transition to a sustainable energy future has been envisaged mainly from a regulatory perspective. In such a role, the public sector provides the push factors---enforcing regulations and providing incentives---to correct market imperfections that impede energy transitions. An alternative and complementary role of the public sector that is now gaining increasing attention is that of catalyzing energy transitions through public sector energy management initiatives. This dissertation offers a conceptual framework to rationalize such a role for the public sector by combining recent theories of sustainable energy transition and public management. In particular, the framework identifies innovative public management strategies (such as performance contracting and procurement) for effectively implementing sustainable energy projects in government facilities. The dissertation evaluates a model of sustainable public sector energy management for promoting energy efficiency in Malaysia. The public sector in Malaysia can be a major player in leading and catalyzing energy efficiency efforts as it is not only the largest and one of the most influential energy consumers, but it also plays a central role in setting national development strategy. The dissertation makes several recommendations on how a public sector energy management strategy can be implemented in Malaysia. The US Federal Energy Management Program (FEMP) is used as a practical model. The analysis, however, shows that in applying the FEMP model to the Malaysian context, there are a number of limitations that will have to be taken into consideration to enable a public sector energy management strategy to be effectively implemented. Overall the analysis of this dissertation contributes to a rethinking of the public sector role in sustainable energy development that can strengthen the sector's credibility both in terms of governance and institutional performance.

    To evaluate the cost-effectiveness of three strategies for the control of taeniasis in a community, in terms of cost per case treated. A study was conducted in South India to determine the prevalence of taeniasis by screening stool samples from 653 randomly chosen subjects, for coproantigens. The costs incurred in the project were used to estimate the cost per case screened and treated. A one-way sensitivity analysis was carried out for varying rates of taeniasis, different screening strategies and mass therapy. Further sensitivity analysis was carried out with different manpower and test costs. The rate of taeniasis as detected by ELISA for coproantigen was 3 per 1000 (2 of 653 samples). Our study showed that mass therapy without screening for taeniasis would be the most economical strategy in terms of cost per case treated if field workers are employed exclusively for either mass therapy or screening. For each strategy, costs per case treated are higher at low prevalence of taeniasis, with a sharp rise below 15%. In places that are endemic for taeniasis and neurocysticercosis, mass therapy or screening for taeniasis should be considered. Screening by stool microscopy is not cost-effective in terms of cost per case of taeniasis treated owing to its low sensitivity. Although the cost per case of taeniasis treated is high at low prevalence of taeniasis for all options, incorporating mass therapy into existing mass drug distribution programmes might prove to be the most cost-effective control strategy. © 2011 Blackwell Publishing Ltd.

    Croatian Government approved its national Radioactive waste and Spent Fuel Strategy as a part of the accession process to EU in July 2009 enabling acquisition of adequate administrative capacity by the time of accession to properly implement and enforce the relevant legislation in all areas related to nuclear safety. Strategy was formulated in line with the Joint Convention on the Safety of Spent Fuel Management and on the Safety of Radioactive Waste Management. In particular, the strategy was approved to ensure that sufficient qualified staff and adequate financial services are available to support the safety of facilities for spent fuel and radioactive waste management generated by Krsko NPP during their operating lifetime and from decommissioning. Following are statements from the Croatian strategy that are relevant for Croatian position regarding capacity building for storage and disposal of LILW and SF. To be able to fulfill the obligations assumed, Croatia needs to do the following (Strategy Section 3.3): reach an agreement with Slovenia by 2013 at the latest regarding the location of objects for storing LILW; should no such agreement be reached, Croatia is to initiate preparations for assuming its half of operational LILW and for third-country export thereof, or for storing the LILW on Croatian territory, whilst also gradually assuming the part of LILW created from decommissioning; reach an agreement with Slovenia by 2018 at the latest regarding the location of a common SF storage; should no such agreement be reached, initiate preparations for assuming a third-country export of SF, or for storing half of SF on Croatian territory. This paper discusses the Strategy aims in the light of noticeable delay of 2nd revision of the Program of NPP Krsko Decommissioning and SF andLILW Disposal, the status of the planned Slovenian national repository on Vrbina site and the prospects of its use for joint Croatian/Slovenian LILW disposal - all in the context of as yet

    Energy harvesting is becoming a viable option for powering small wireless devices. Energy for data transmission is supplied by the nature, such that when a transmission is about to take place in an arbitrary instant, the amount of available energy is a random quantity. The arrived energy is stored...... in a battery and transmissions are interrupted if the battery runs out of energy. We address communication in slot-based energy harvesting systems, where the transmitter communicates with ON-OFF signaling: in each slot it can either choose to transmit (ON) or stay silent (OFF). Two different models...... strategies and compare the slot- with the frame-based model in the case of an errorless transmission channel. Additionally, for the slot-based model and channel with errors, we provide a new proof of the capacity achieved by the save-and-transmit scheme....

    International Nuclear Information System (INIS)

    1981-01-01

    Within the coming decades a transition must be initiated from oil and gas to 'unlimited' primary energy sources, i.e., nuclear and solar energy. Ever more expensive fossil energy forms will have to provide for an intermediary solution to the growing global energy demand. While a rather clear-cut picture of the energy problem has emerged on the global level, a straightforward translation to the national or even to the company level is not available. The current study contract between the European Economic Community and the International Institute for Applied Systems Analysis (IIASA) is a first exercice designed to transfer the global results to the intermediary level of the ''Subregion'' of the European Community. In operational terms the contract aims at identifying long-term (up to 2030) alternative energy R and D strategies for twelve European countries that would be consistent with the global scenarios, identified by IIASA

  9. Mission aware energy saving strategies for Army ground vehicles

    Science.gov (United States)

    Dattathreya, Macam S.

    Fuel energy is a basic necessity for this planet and the modern technology to perform many activities on earth. On the other hand, quadrupled automotive vehicle usage by the commercial industry and military has increased fuel consumption. Military readiness of Army ground vehicles is very important for a country to protect its people and resources. Fuel energy is a major requirement for Army ground vehicles. According to a report, a department of defense has spent nearly $13.6 billion on fuel and electricity to conduct ground missions. On the contrary, energy availability on this plant is slowly decreasing. Therefore, saving energy in Army ground vehicles is very important. Army ground vehicles are embedded with numerous electronic systems to conduct missions such as silent and normal stationary surveillance missions. Increasing electrical energy consumption of these systems is influencing higher fuel consumption of the vehicle. To save energy, the vehicles can use any of the existing techniques, but they require complex, expensive, and time consuming implementations. Therefore, cheaper and simpler approaches are required. In addition, the solutions have to save energy according to mission needs and also overcome size and weight constraints of the vehicle. Existing research in the current literature do not have any mission aware approaches to save energy. This dissertation research proposes mission aware online energy saving strategies for stationary Army ground vehicles to save energy as well as to meet the electrical needs of the vehicle during surveillance missions. The research also proposes theoretical models of surveillance missions, fuzzy logic models of engine and alternator efficiency data, and fuzzy logic algorithms. Based on these models, two energy saving strategies are proposed for silent and normal surveillance type of missions. During silent mission, the engine is on and batteries power the systems. During normal surveillance mission, the engine is

    Deutsch, K.

    2005-01-01

    This presentation outlined the energy policy in the United States and its impact on frontier development in Alaska, deepwater offshore fields and in the western oil shale resources. The energy strategy focuses on technologies that increase domestic production from existing resources as well as technologies that create new sources of energy. In addition to emphasizing the cooperation between Canada and the United States in ensuring energy supply security and stability, this paper discussed the importance of overall bilateral trade between the 2 countries. It was noted that Canada is the United State's most secure and reliable energy partner and is the number 1 supplier of imported oil, natural gas, electricity and uranium. The Bush administration's energy policy is based on the mandate to supply stable, reliable, secure, affordable and environmentally sound energy for the country's growing economy. The energy strategy focuses on increasing energy supplies, promoting energy conservation, repairing and modernizing the energy infrastructure, protecting the environment and improving energy security. Basic changes to the way energy is produced and used will be needed in order to meet these challenges. Energy security can be met through efficiency gains, diversification and use of alternative energy sources. The strategy involves a balance of supply sources, ranging from increasing domestic oil and gas production to such sources as clean coal generation, nuclear power and hydropower. The policy also balances the use of traditional energy sources with renewables such as geothermal, solar, wind and hydrogen. The United States, Canada and Mexico have identified the following 9 areas as critical for interaction on energy: energy data, electricity, regulatory cooperation, energy efficiency, natural gas, oil sands, nuclear and energy science and technology. Construction of the Alaska Natural Gas Pipeline is also one of the Bush administration's highest priorities, along with

    The aim of the study was to examine the use of Porter's generic strategies and their effect on performance in the context of the Slovak hospital industry. Using mail survey the study first identified the natural taxonomy of four strategic types of Slovak hospitals, based on their use of Porter's generic strategies in pure form and in combination. Next the study examined whether different strategic types were associated with different levels of organisational performance, while controlling for such variables as size and location, which have been argued to influence the hospital performance. The findings indicate that hospitals which follow a "stuck-in-the-middle" strategy, in general, have superior performance on all used performance measures, while hospitals that place only low emphasis on cost leadership, differentiation and focus, labelled "wait and see" in this study, perform the poorest. The study concludes that the research provided body of knowledge relevant for the Slovak hospital industry, that may be used by hospital managers in the strategy formulation process as well as by the researches in exploring the influence of different contingencies on hospitals' strategic orientation.

    Highlights: • The power usage for battery-powered electrical vehicles with in-wheel motors is maximized. • The battery and motor dynamics are examined emphasized on the power conversion and utilization. • The optimal control strategy is derived and verified by simulations. • An analytic expression of the optimal operating point is obtained. - Abstract: Due to limited energy density of batteries, energy management has always played a critical role in improving the overall energy efficiency of electric vehicles. In this paper, a key issue within the energy management problem will be carefully tackled, i.e., maximizing the power usage of batteries for battery-powered electrical vehicles with in-wheel motors. To this end, the battery and motor dynamics will be thoroughly examined with particular emphasis on the power conversion and power utilization. The optimal control strategy will then be derived based on the analysis. One significant contribution of this work is that an analytic expression for the optimal operating point in terms of the component and environment parameters can be obtained. Owing to this finding, the derived control strategy is also rendered a simple structure for real-time implementation. Simulation results demonstrate that the proposed strategy works both adaptively and robustly under different driving scenarios

    The problem of optimum long-term development of the nuclear energy system is considered. The optimum strategies (i.e. minimum total uranium consumption) for the transition phase leading to a stationary regime of development are found. For this purpose the author has elaborated a new method of solving linear problems of optimal control which can include jumps in trajectories. The method gives a possibility to fulfil a total synthesis of optimum strategies. A key characteristic of the problem is the productivity function of the nuclear energy system which connects technological system parameters with its growth rate. There are only two types of optimum strategies, according to an increasing or decreasing productivity function. Both cases are illustrated with numerical examples. (orig.) [de

    Full Text Available Energy system in Serbia, in the whole energy chain, from exploitation of primary energy sources, transformations in electric power plants and district heating plants, energy (electric and heat transmission and distribution to final users, and up to final energy consumption, is faced with a number of irrational and inefficient behavior and processes. In order to fight with such situation National Energy Efficiency Program, financed by the Ministry of Science and Environmental Protection has been founded in 2001. Basic facts about status of energy sector in Serbia, with special emphasis on the energy efficiency and use of renewable energy sources have been given in the review paper published in the issue No. 2, 2006 of this journal. In present paper new strategy and priorities of the National Energy Efficiency Program for the future period from 2006 to 2008, and beyond, is presented. This strategy and priorities are mainly based on the same concept and principles as previous, but new reality and new and more simulative economic and financial environment in energy sector made by the Energy low (accepted by Parliament in 2004 and Strategy of Development of Energy Sector in Republic Serbia up to 2015 (accepted by the Parliament in May 2005, have been taken into account. Also, responsibilities that are formulated in the Energy Community Treaty signed by the South-East European countries, and also coming from documents and directives of the European Community and Kyoto Protocol are included in new strategy. Once again necessity of legislative framework and influence of regulations and standards, as well as of the governmental support, has been pointed out if increased energy efficiency and increased use of renewable energy sources are expected. .

    Wolf, Franziska; Surroop, Dinesh; Singh, Anirudh; Leal, Walter

    2016-01-01

    Small Islands Developing States (SIDS) are isolated and surrounded by ocean. The generation and use of energy resources are two very important aspects for the development of SIDS. Unfortunately, most of SIDS do not use their potential in respect of energy resources, and they as a result have to depend on the import of fossil fuels in order to meet their energy needs. This increases the overall vulnerability of SIDS as they have to depend on the rising or fluctuating fossil fuels prices. Some SIDS, especially in the geographically dispersed Pacific region, do not have proper access to energy whereas other SIDS struggle more with energy security issue. At the same time, SIDS are most vulnerable to the impacts and effects of climate change, as they are among the ones to be most severely affected in case of natural calamities and sea-level rise. Drawing on experiences from Fiji and Mauritius, this paper explains core elements related to energy access and security in SIDS, contextualizes and discusses barriers and list some of the strategies that may be used to ensure access to and a continuous supply of energy in SIDS. A situational analysis of two SIDS outlines their current energy situation and compares their energy policies to globally accepted criteria for SIDS policies as well as with each other. It is claimed that the diverging energy performances of Fiji and Mauritius cannot be explained by policies differences. The reasons for the varying energy performances may therefore lie in the administrative and institutional mechanisms used by the two countries in implementing their energy policies. Finally, to enable SIDS to reduce their overall vulnerability and become truly sustainable islands, it is recommended to undertake careful assessments of the particular local contexts under which island energy regimes operate. - Highlights: • Core elements related to energy access/security in SIDS, barriers and strategies. • Situational analysis of two SIDS: Fiji and

    2007-01-01

    Energy is essential for human societies. Energy systems, though, are also associated with several adverse environmental effects. So far societies have been unable to successfully change their energy systems in a way that addresses environmental and health concerns. Lack of policy consensus often resulted in so-called 'stop-go' policies, which were identified as some of the most important barriers regarding successful energy transitions. The lack of policy consensus and coherent long-term strategies may result from a lack of knowledge of energy systems' meso-level dynamics. The meso-level involves the dynamic behaviour of the individual system elements and the coupling of individual technologies, resulting in interdependencies and regimes. Energy systems are at the meso-level characterised by two typical aspects, i.e. dynamics driven by interactions between actors, and heterogeneous characteristics of actors. These aspects give rise to the ineffectiveness of traditional energy policies, which is illustrated with examples from the transport sector and household electricity consumption. We found that analysis of energy systems at the meso-level helps to better understand energy systems. To resolve persistent policy issues, the traditional 'one size fits all' energy policies are not sufficient. In order to tackle the difficult issues, 'redesign of system organisation', 'target group approach', or 'target group induced system re-orientation' are needed

    The status and role of nuclear energy in the sustainable energy development strategy in China are discussed in this research report. Specifically, the role of nuclear energy in meeting the requirements of energy and electricity supply, environment protection and greenhouse gas (GHG) emission-reduction is focused on. The report is mainly composed of three component parts. The serious situation and challenges concerning the national energy security and energy sustainable development, and major tasks proposed to carry out the strategy of energy sustainable development are expounded in the first part. In the second part, the position and role of nuclear energy in China are elaborated and analyzed in detail. Firstly, it is indicated that the development of nuclear energy is the objective requirement for optimizing national energy structure. From the viewpoint of climate and environment protection, energy mix is required to transit from conventional fossil fuels to clean and high-quality energy sources. The potential role of nuclear energy in energy structure optimization in China is compared with that of hydro and other renewable energy sources. Secondly, it is proposed that the development of nuclear energy is the important security option for safely supplying the national energy and electricity in the future, mainly from the point of nuclear power providing stable and reliable power supply, relieving the burden of coal exploitation and transportation and reducing the risk of energy security caused by dependence on oil and natural gas. Thirdly, it is elaborated that the development of nuclear energy is the inevitable selection for carrying out the national energy and electricity sustainable development. It is given further details that nuclear energy is a clean and economical energy option, a preference coinciding with the principles of the circular economy, a feasible technical choice to greatly reduce emission of greenhouse gases, a selection contributing to

The strategy prioritized the development of hydro-electricity, wind energy potential, hydrocarbon reserves, and the diversification of natural gas supplies. Greater communication between government agencies, local communities and First Nations groups was recommended. Energy efficiency measures were outlined. The strategy emphasized Quebec's future role as a leader in the sustainable development field. It was stated that electricity rates will be set at a level that promotes the interests of Quebec while ensuring proper management of resources, improved price signals and customer protection. Orientations and priority actions to achieve the strategy's objectives include: (1) resumption and acceleration of developing hydroelectric potential through a variety of new projects totalling 4500 MW within the next 5 years, (2) the exploitation of Quebec's estimated 4000 MW of potential wind power, (3) increasing the overall energy efficiency target by a factor of 8 compared to current targets to allow for $2.5 billion in annual savings for consumers, (4) supporting and promoting innovation financed through part of the levy garnered on all forms of energy with a particular priority on biomass energy development, (5) developing the oil and gas resources in the Gulf of St. Lawrence and estuary, and (6) responding more effectively to the predicament of low-income households.

    This paper proposes a novel topology of multimode hybrid energy storage system (HESS) and its energy management strategy for electric vehicles (EVs). Compared to the conventional HESS, the proposed multimode HESS has more operating modes and thus it could in further enhance the efficiency of the system. The rule-based control strategy and the power-balancing strategy are developed for the energy management strategy to realize mode selection and power distribution. Generally, the DC-DC converter will operate at peak efficiency to convey the energy from the batteries to the UCs. Otherwise, the pure battery mode or the pure ultracapacitors (UCs) mode will be utilized without the DC-DC converter. To extend the battery life, the UCs have the highest priority to recycle the energy and the batteries are isolated from being recharged directly during regenerative braking. Simulations and experiments are established to validate the proposed multimode HESS and its energy management strategy. The results reveal that the energy losses in the DC-DC converter, the total energy consumption and the overall system efficiency of the proposed multimode HESS are improved compared to the conventional HESS.

    In August 2009, after 54 years of virtually unbroken rule, Japan's Liberal Democratic Party (LDP) was ousted from power by the Democratic Party of Japan (DPJ). The DPJ's campaign platform included a pledge to facilitate extreme reductions in greenhouse gas (GHG) emissions. Yet, at the COP16 meeting in Cancun, Japan announced that it would not accept further emission reduction targets without broader commitment from all nations. This paper seeks to explain this dichotomy by employing a targeted stakeholder evaluation based on surveys with 321 Japanese citizens to assess the extent to which influential stakeholder groups in Japan supports a potentially costly transition to a low-carbon energy infrastructure amidst severe economic challenges that the nation faces. Findings help explain Japan's adversarial role in COP16 negotiations in Cancun, despite the stated GHG reduction ambitions of Japan's current ruling party. The analysis concludes that if the DPJ does embrace aggressive CO 2 reduction targets in the future, the strategic focus will likely mirror the former ruling party's energy policy of bolstering nuclear power generation capacity and promoting energy efficiency improvements while exhibiting lukewarm commitment to supporting capacity development in alternative sources of energy supply such as solar panels and wind turbines. - Research highlights: → Public consensus exists regarding which energy policy goals are important in Japan. → Minor perceptual differences are not of a catalytic nature. → Public consensus does not deviate significantly from past LDP energy policy. → Unlikely that the DPJ will pursue costly energy transition initiatives. → Likely that the DPJ energy strategy will be substantively similar to LDP strategy. → Any differences in strategy will focus on CO 2 reduction magnitude not substance.

    The association between low socioeconomic status (SES) and obesity is well documented. In the current research, a life history theory (LHT) framework provided an explanation for this association. Derived from evolutionary behavioral science, LHT emphasizes how variability in exposure to unpredictability during childhood gives rise to individual differences in a range of social psychological processes across the life course. Consistent with previous LHT research, the current findings suggest that exposure to unpredictability during childhood (a characteristic common to low SES environments) is associated with the adoption of a fast life-history strategy, one marked by impulsivity and a focus on short-term goals. We demonstrate that a fast life-history strategy, in turn, was associated with dysregulated weight-management behaviors (i.e., eating even in the absence of hunger), which were predictive of having a high body mass index (BMI) and being obese. In both studies, findings held while controlling for participants' current socioeconomic status, suggesting that obesity is rooted in childhood experiences. A serial mediation model in study 2 confirmed that effects of childhood SES on adult BMI and obesity can be explained in part by exposure to unpredictability, the adoption of a fast life-history strategy, and dysregulated-eating behaviors. These findings suggest that weight problems in adulthood may be rooted partially in early childhood exposure to unpredictable events and environments. LHT provides a valuable explanatory framework for understanding the root causes of obesity.

    2014-01-01

    This paper is a review of the most recent literature on the interaction between climate change, land-use and energy, based on the analysis of papers collected through the most relevant scientific literature databases. A total of 114 papers published between 2000 and 2011 were reviewed. The aims of this review are: in general (1) to identify the different research topics that have been developed related to the interaction between climate change, land-use and energy; more specifically, (2) to analyze what are the most suitable spatial and temporal scales of investigation to focus on for actions and strategies to reduce critical issues in the field of energy and environment; (3) to identify which actions and strategies are deemed as the most appropriate to mitigate critical issues in energy and environment; and given the research gaps found in the review, (4) to propose research recommendations in the context of effective climate-energy planning. We argue that there are certain gaps and needs for a “nested” environmental governance. It is necessary to understand how different environmental policies overlap and how they can be integrated in order to verify whether there are conflicting targets that may negate each other in the long term. - Highlights: • Energy production and consumption can directly or indirectly affect climate change. • Energy sector is influenced directly and indirectly by changes in climate conditions. • Energy sector and climate change affect and limit alternative uses of land, causing land-use changes. • The most suitable spatial scale for energy planning is the municipal level requiring short-term perspectives. • Several research recommendations to deal with the complexity of energy-land-use-climate change issue are proposed

    Systems analyses were carried out by the International Energy Agency for the participating 15 countries in order to work out strategies and scenarios for lessening the dependence on imported oil and for developing new energy technologies. MARKAL model computations show the technology and energy mixes necessary for achieving a reduction of oil imports by two thirds over the next 40 years. The scenario 'high social security' examines the projected rise in energy consumption, the development of oil substitutes, the increase in alternative heating sources, the development of markets for liquid energy products, the demand for gas, and the relative usage of various energy generation methods. The recommended strategy involves as the most important points an increase in coal consumption, greater nuclear energy reliance and development of alternative technologies.

    This examination of the mediation strategies of a very popular factual science comic strip series from the 1960s and 1970s illustrates, in this case by highlighting the ways in which women were targeted as an audience, that science popularisations are always political. For that reason, they should not be evaluated merely in terms of scientific accuracy. I demonstrate tensions between the dissemination model of communication used in the distribution of science popularisations, on the one hand, with the advocacy of a dialogue model in their content, on the other. © The Author(s) 2015.

The two most challenging barriers perceived by the companies are need for capital and need for supportive political schemes. Our findings reveal that internationalization certainly is a common strategy to access capital and attractive support schemes in foreign countries.

  16. Network switching strategy for energy conservation in heterogeneous networks.

    Directory of Open Access Journals (Sweden)

    Yujae Song

    Full Text Available In heterogeneous networks (HetNets, the large-scale deployment of small base stations (BSs together with traditional macro BSs is an economical and efficient solution that is employed to address the exponential growth in mobile data traffic. In dense HetNets, network switching, i.e., handovers, plays a critical role in connecting a mobile terminal (MT to the best of all accessible networks. In the existing literature, a handover decision is made using various handover metrics such as the signal-to-noise ratio, data rate, and movement speed. However, there are few studies on handovers that focus on energy efficiency in HetNets. In this paper, we propose a handover strategy that helps to minimize energy consumption at BSs in HetNets without compromising the quality of service (QoS of each MT. The proposed handover strategy aims to capture the effect of the stochastic behavior of handover parameters and the expected energy consumption due to handover execution when making a handover decision. To identify the validity of the proposed handover strategy, we formulate a handover problem as a constrained Markov decision process (CMDP, by which the effects of the stochastic behaviors of handover parameters and consequential handover energy consumption can be accurately reflected when making a handover decision. In the CMDP, the aim is to minimize the energy consumption to service an MT over the lifetime of its connection, and the constraint is to guarantee the QoS requirements of the MT given in terms of the transmission delay and call-dropping probability. We find an optimal policy for the CMDP using a combination of the Lagrangian method and value iteration. Simulation results verify the validity of the proposed handover strategy.

    Buildings are an important contributor to China's energy consumption and attendant CO 2 emissions. Measures to address energy consumption and associated emissions from the buildings sector will be an important part of strategy to reduce the country's CO 2 emissions. This study presents a detailed, service-based model of China's building energy demand, nested in the GCAM (Global Change Assessment Model) integrated assessment framework. Using the model, we explored long-term pathways of China's building energy demand and identified opportunities to reduce greenhouse gas emissions. A range of different scenarios was also developed to gain insights into how China's building sector might evolve and what the implications might be for improved building energy technology and carbon policies. The analysis suggests that China's building energy growth will not wane anytime soon, although technology improvement will put downward pressure on this growth: In the reference scenarios, the sector's final energy demand will increase by 110–150% by 2050 and 160–220% by 2095 from its 2005 level. Also, regardless of the scenarios represented, the growth will involve the continued, rapid electrification of the buildings sector throughout the century, and this transition will be accelerated by the implementation of carbon policy. -- Highlights: ► We developed a building energy model for China, nested in an integrated-assessment framework. ► We explore long-term pathways of China's building energy use by implementing a range of scenarios. ► China's building energy consumption will continue to grow and be electrified over the century. ► Improved building energy technology will slow down the growth in building energy consumption. ► Electrification will be accelerated by the implementation of carbon policy.

    2012-01-01

    The Greek energy system is one of the most carbon intensive energy systems in Europe. Hydrocarbons and solid fuels (lignite) cover over 80% of the final energy demand. The main objective of this work is to build energy scenarios for the future – with a focus on the electricity production system – and explore how these scenarios are reflected in economic, environmental terms and in terms of energy efficiency. The main tool which is used in the scenario analysis is LEAP (Long range Energy Alternatives Planning System). The scenarios are essentially the result of developing “storylines” driven by the uncertainties which cannot be controlled by the analysts or decision makers, and technical and non-technical options the analyst or decision maker may choose from. A set of uncertainties is considered as a possible future or storyline, and one or more options can be selected as a possible strategy. The combination of a storyline and a specific strategy gives a scenario. The main uncertainties for the Greek energy system are identified and various technical options are explored. Rather than using a model which leads to optimum strategies from a set of alternatives, the model in use will apply different strategies. - Highlights: ► A demand-driven approach was used to build energy scenarios for the Greek interconnected system. ► Each Scenario consists of a possible future and a strategy. ► High RES penetration will decrease CO 2 emissions but it will also increase capital cost. ► Carbon intensity is reduced in all the scenarios.

    Energy is a significant cost in the economics of desalinating waters, but water scarcity is driving the rapid expansion in global installed capacity of desalination facilities. Conventional fossil fuels have been utilized as their main energy source, but recent concerns over greenhouse gas (GHG) emissions have promoted global development and implementation of energy minimization strategies and cleaner energy supplies. In this paper, a comprehensive review of energy minimization strategies for membrane-based desalination processes and utilization of lower GHG emission renewable energy resources is presented. The review covers the utilization of energy efficient design, high efficiency pumping, energy recovery devices, advanced membrane materials (nanocomposite, nanotube, and biomimetic), innovative technologies (forward osmosis, ion concentration polarization, and capacitive deionization), and renewable energy resources (solar, wind, and geothermal). Utilization of energy efficient design combined with high efficiency pumping and energy recovery devices have proven effective in full-scale applications. Integration of advanced membrane materials and innovative technologies for desalination show promise but lack long-term operational data. Implementation of renewable energy resources depends upon geography-specific abundance, a feasible means of handling renewable energy power intermittency, and solving technological and economic scale-up and permitting issues.

    The Global Nuclear Vision Project is examining, using scenario building techniques, a range of long-term nuclear energy futures. The exploration and assessment of optimal nuclear fuel-cycle and material strategies is an essential element of the study. To this end, an established global E 3 (energy/economics/environmental) model has been adopted and modified with a simplified, but comprehensive and multi-regional, nuclear energy module. Consistent nuclear energy scenarios are constructed using this multi-regional E 3 model, wherein future demands for nuclear power are projected in price competition with other energy sources under a wide range of long-term demographic (population, workforce size and productivity), economic (price-, population-, and income-determined demand for energy services, price- and population-modified GNP, resource depletion, world-market fossil energy prices), policy (taxes, tariffs, sanctions), and top-level technological (energy intensity and end-use efficiency improvements) drivers. Using the framework provided by the global E 3 model, the impacts of both external and internal drivers are investigated. The ability to connect external and internal drivers through this modeling framework allows the study of impacts and tradeoffs between fossil- versus nuclear-fuel burning, that includes interactions between cost, environmental, proliferation, resource, and policy issues

    2004-01-01

    This paper investigates the role of suppliers of a new energy technology, when the market for that technology continues to be in a state of flux, and is characterised by continued regulatory and institutional developments. This paper first summarises the institutional drivers resulting in the widely divergent diffusion of distributed generation (DG) based on natural gas engines in the Netherlands and the UK. Then, supplier responses to this institutionally driven market are discussed. Under regulatory support, supply firms were able to implement innovative operational and ownership arrangements, hugely growing the market while positioning themselves for new R and D and market developments. Under regulatory restrictions, supply firms fought to survive, with resultant implications for the reputation and longer term prospects for this new energy technology. The paper concludes by discussing how continuing institutional instability can limit the supplier strategies based on spillovers from successful regulatory experiments, Thus, the establishment of a viable energy supply industry is delayed under continuing regulatory uncertainty.

Enterprise in Higher Education (EHE has funded five pilot RBL projects during the past year, including one in introductory economics. The project was managed by three lecturers in the School of Social Sciences, supported by an Academic Development Officer. Learning outcomes were completely revised, and a range of assessment strategies, including computer-based tests, was identified. A resources guide was produced which identified the materials and activities that would enable students to achieve the learning outcomes. A number of innovations were adopted, including: • computer-based curriculum delivery, assessment, and student evaluation of the course; • an open approach to assessment; • abolishing lectures in favour of a diverse range of teaching and learning activities.

  6. WELMM approach to energy strategies and options. [Water, energy, land, materials, and manpower

    Energy Technology Data Exchange (ETDEWEB)

    Grenon, M; Lapillonne, B

    1976-12-01

    The development of energy resources requires more and more natural or human resources--on the one hand because of the difficulty of ''harvesting'' primary energy resources, and on the other because of the complexity of the sequence of processes necessary to convert these primary resources into useful resources for an economy (final energy). In this context the WELMM approach has been designed to evaluate the resource requirements for the development of energy resources. WELMM focuses mainly on five limited resources: water, energy, land, materials, and manpower. The WELMM evaluation is implemented at the level of the major facilities concerned in the harvesting and conversion of primary energy resources into final resources. All the WELMM data are stored in three different data bases (Resource Data Base, Component Data Base, and Facility Data Base). They are meant to be used to enlarge and complete the traditional economic comparison of energy processes, energy strategies, or energy options.

    Daylighting is recognized as an important element in architecture and a useful strategy in energy-efficient building designs. Daylight gives a sense of cheeriness and brightness that can have a significant positive impact on the people. There is a scope for integrating daylight with electric light to reduce building energy use. The amount of daylight entering a building is mainly through window openings, which create in the indoor environment a more attractive and pleasing atmosphere, in addition to maximise visual access to the pleasant views of the outside world. Determinations of the exterior and interior daylight and lighting energy savings are key issues to demonstrate the benefits based on daylighting designs. This paper provides a review of daylight illuminance determinations and the lighting energy reductions due to daylighting schemes. The study includes daylight measurements, prediction of daylight illuminance under various sky conditions and potential electric lighting energy savings from daylight-linked lighting controls. The article aims at providing building professionals, practitioners and researchers more information and a better understanding of daylight for promoting effective daylighting designs and evaluations.

  8. Output and substitution elasticities of energy and implications for renewable energy expansion in the ECOWAS region

    Wesseh, Presley K.; Lin, Boqiang

    2016-01-01

    This study estimates output and substitution elasticities of renewable energy and nonrenewable energy for the Economic Community of West African States (ECOWAS) and discusses implications for expanding the former. The results show that nonrenewable energy promises greater benefits for ECOWAS economic transition, with output elasticities averaging between 0.052–0.579 and −0.055 to 0.223 for nonrenewable energy and renewable energy respectively. Overall estimated technological progress is low (−0.5% to 2.6%); the bulk coming from input efficiency. Substitution elasticities (0.02–0.94) suggest potential for switching towards renewable energy. Notwithstanding, scale, economics and sitting problems inherent in renewable power generation challenge the opportunities for energy substitution. A sustainable policy solution, therefore, appears to be one favoring scaled and efficient electricity generation from fossil energy in the short-run with a gradual switch towards renewable power in the long-run. In general, the applied model provides insights that energy efficiency enhances sustainable growth by propelling technological advancement especially when technical change is scale-biased and factor-augmenting. The study also provides insights that impacts of exogenous shocks to inputs are temporary, and hence, do not jeopardize efforts aimed at scaling output through increased and efficient use of labor, capital and energy; especially nonrenewable energy. - Highlights: • Output and substitution elasticities of energy are estimated for the ECOWAS region. • Nonrenewable energy promises greater opportunities for economic growth. • Technical progress is low and driven mainly by the efficiency of inputs. • Energy efficiency drives technological innovation. • Potential of switching towards renewable energy is high but suffers feasibility gaps.

    The energy industry, accounts for the largest portion of CO 2 emissions, is facing the issue of compliance with the national clean energy policy. The methodology for evaluating the energy mix policy is crucial because of the characteristics of lead time embedded with the power generation facilities investment and the uncertainty of future electricity demand. In this paper, a modified binomial model based on sequential compound options, which may account for the lead time and uncertainty as a whole is established, and a numerical example on evaluating the optional strategies and the strategic value of the cleaner energy policy is also presented. It is found that the optimal decision at some nodes in the binomial tree is path dependent, which is different from the standard sequential compound option model with lead time or time lag concept. The proposed modified binomial sequential compound real options model can be generalized and extensively applied to solve the general decision problems that deal with the long lead time of many government policies as well as capital intensive investments. - Highlights: → Introducing a flexible strategic management approach for government policy making. → Developing a modified binomial real options model based on sequential compound options. → Proposing an innovative model for managing the long term policy with lead time. → Applying to evaluate the options of various scenarios of cleaner energy strategies.

    This paper focuses on the best strategy for New Zealand to follow in order to meet obligations under the Framework Convention on Climate Change (FCCC). The New Zealand government's current policy is to rely on the increased carbon storage in commercial tree plantings to meet 80% of FCCC obligations with the balance being met by policy measures including voluntary energy efficiency agreements with industry and enhanced state support for energy efficiency activities. If targets are not on track for achievement by 2000, the government will introduce a carbon charge in 1997. An alternative strategy involving microeconomic reforms in the electricity and transport sectors and tradable abatement obligations including credits for emission reductions and carbon storage is proposed. 1 fig., 11 refs

    This current report updates a previous report (February 1979) and brings to light many new factors; a comparative analysis of global impacts is presented, particular emphasis being given to large scale equilibria, and equivalent, but different energy strategies and policies. The way in which different energy strategies might reduce externally imposed constraints is examined in detail, i.e. enabling higher economic growth to be achieved, and unemployment to be reduced without increasing or even with a decrease in the external balance-of-payments deficit. A reference electricity generating program (realized with coal, oil or uranium) similar to the medium and long term French nuclear program was retained. Attention was given to ensure that the ratio between the amount of electricity generated and the total electricity requirements remained realistic. This was also true for the ratio between the amount of nuclear origin generated electricity and the total amount of electricity generated [fr

    The United States is facing unprecedented challenges in climate change and energy security. President-elect Obama has called for a reduction of CO2 emissions to 1990 levels by 2020, with a further 80% reduction by 2050. Meeting these aggressive goals while gradually increasing the overall energy supply requires that all non-emitting technologies must be advanced. The development and deployment of nuclear energy can, in fact, help the United States meet several key challenges: (1) Increase the electricity generated by non-emitting sources to mitigate climate change, (2) Foster the safe and proliferation-resistant use of nuclear energy throughout the world, (3) Reduce the transportation sector's dependence on imported fossil fuels, and (4) Reduce the demand on natural gas for process heat and hydrogen production. However, because of the scale, cost, and time horizons involved, increasing nuclear energy's share will require a coordinated research effort-combining the efforts of industry and government, supported by innovation from the research community. This report outlines the significant nuclear energy research and development (R and D) necessary to create options that will allow government and industrial decision-makers to set policies and create nuclear energy initiatives that are decisive and sustainable. The nuclear energy R and D strategy described in this report adopts the following vision: Safe and economical nuclear energy in the United States will expand to address future electric and non-electric needs, significantly reduce greenhouse gas emissions and provide energy diversity, while providing leadership for safe, secure and responsible expansion of nuclear energy internationally

    This study reviews the environmental implications of continued and increased use of biomass for energy to determine what concerns have been and need to be addressed and to establish some guidelines for developing future resources and technologies. Although renewable biomass energy is perceived as environmentally desirable compared with fossil fuels, the environmental impact of increased biomass use needs to be identified and recognized. Industries and utilities evaluating the potential to convert biomass to heat, electricity, and transportation fuels must consider whether the resource is reliable and abundant, and whether biomass production and conversion is environmentally preferred. A broad range of studies and events in the United States were reviewed to assess the inventory of forest, agricultural, and urban biomass fuels; characterize biomass fuel types, their occurrence, and their suitability; describe regulatory and environmental effects on the availability and use of biomass for energy; and identify areas for further study. The following sections address resource, environmental, and policy needs. Several specific actions are recommended for utilities, nonutility power generators, and public agencies.

    The simulations used in the field of high energy physics are compute intensive and exhibit a high level of data parallelism. These features make such simulations ideal candidates for Grid computing. We are taking as an example the GEANT4 detector simulation used for physics studies within the ATLAS experiment at CERN. One key issue in Grid computing is that of network and system security, which can potentially inhibit the widespread use of such simulations. Virtualization provides a feasible solution because it allows the creation of virtual compute nodes in both local and remote compute clusters, thus providing an insulating layer which can play an important role in satisfying the security concerns of all parties involved. However, it has performance implications. This study provides quantitative estimates of the virtualization and hyper-threading overhead for GEANT on commodity clusters. Results show that virtualization has less than 15% run time overhead, and that the best run time (with the non-SMP licens...

    1997-01-01

    The shift of the focus of the vertically integrated model to the new unbundled models of organization to attain a ''new competitive'' Electricity Supply Industry brings new subjects into IRP (Integrated Resource Planning) study. The decision centralization on new capacity additions is being substituted by market mechanisms, changing the implementation of the IRP regarding both the construction of new capacity and the DSM. The implication for DSM is that, without a central planning process, it will not be possible to carry out IRP. In some countries they are implementing policies tending to create a more favourable attitude towards energy efficiency, in products and services. The conventional programmes of Demand-Side Management are being redesigned as added-value services to conserve or create market quota through Market Transformation mechanisms, such as Technology Procurement.

  19. The Grand Strategy of Nonstate Actors: Theory and Implications

    Directory of Open Access Journals (Sweden)

    Garrett Pierman

    2015-12-01

    Full Text Available This article addresses the Realist assumption that only actors that are states can be considered to have a strategic culture. The primary issue raised is the question of the ability of non-state actors to have a strategic culture. Al-Qaida is used as a theoretical case study. Ultimately this article rejects the idea of territoriality in strategic culture formulation and calls for academics and policymakers alike to adopt a broader conception of actors on the international, stage. This broader conception of actors would necessitate rich case studies to be done in the future in order to seek an understanding of the strategic culture of the non-state actors which academics and policymakers must deal with in the modern security environment. In particular, the article finds that the assumptions held about al-Qaida thus far are wrong and, in reality, the group has ambitions that are cosmic in nature, which will necessitate change in the strategies used to fight against terrorism.

    2011-08-01

    Adenoviral (Ad) vectors have emerged as a promising gene delivery platform for a variety of therapeutic and vaccine purposes during last two decades. However, the presence of preexisting Ad immunity and the rapid development of Ad vector immunity still pose significant challenges to the clinical use of these vectors. Innate inflammatory response following Ad vector administration may lead to systemic toxicity, drastically limit vector transduction efficiency and significantly abbreviate the duration of transgene expression. Currently, a number of approaches are being extensively pursued to overcome these drawbacks by strategies that target either the host or the Ad vector. In addition, significant progress has been made in the development of novel Ad vectors based on less prevalent human Ad serotypes and nonhuman Ad. This review provides an update on our current understanding of immune responses to Ad vectors and delineates various approaches for eluding Ad vector immunity. Approaches targeting the host and those targeting the vector are discussed in light of their promises and limitations.

  1. Real Time Energy Management Control Strategies for Hybrid Powertrains

    Science.gov (United States)

    Zaher, Mohamed Hegazi Mohamed

    In order to improve fuel efficiency and reduce emissions of mobile vehicles, various hybrid power-train concepts have been developed over the years. This thesis focuses on embedded control of hybrid powertrain concepts for mobile vehicle applications. Optimal robust control approach is used to develop a real time energy management strategy for continuous operations. The main idea is to store the normally wasted mechanical regenerative energy in energy storage devices for later usage. The regenerative energy recovery opportunity exists in any condition where the speed of motion is in opposite direction to the applied force or torque. This is the case when the vehicle is braking, decelerating, or the motion is driven by gravitational force, or load driven. There are three main concepts for regernerative energy storing devices in hybrid vehicles: electric, hydraulic, and flywheel. The real time control challenge is to balance the system power demand from the engine and the hybrid storage device, without depleting the energy storage device or stalling the engine in any work cycle, while making optimal use of the energy saving opportunities in a given operational, often repetitive cycle. In the worst case scenario, only engine is used and hybrid system completely disabled. A rule based control is developed and tuned for different work cycles and linked to a gain scheduling algorithm. A gain scheduling algorithm identifies the cycle being performed by the machine and its position via GPS, and maps them to the gains.

  2. Local energy governance in vermont: an analysis of energy system transition strategies and actor capacity

    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

    The status and role of nuclear energy in the energy security and sustainable energy development strategy in China are discussed. Specifically, the role of nuclear energy in meeting the requirements of energy and electricity supply, environment protection and greenhouse gas (GHG) emission-reduction is focused on. The report is mainly composed of three component parts. The serious situation and challenges concerning the national energy security and energy sustainable development are expounded. It is indicated that the development of nuclear energy is the objective requirement for optimizing national energy structure. It is proposed that the development of nuclear energy is the important security option for safely supplying the national energy and electricity in the future. It is elaborated that the development of nuclear energy is the inevitable selection for carrying out the national energy and electricity sustainable development. Nuclear energy is a preference coinciding with the principles of the circular economy, a selection contributing to improvement of ecological environment and an inexhaustible resource in the long term. Some suggestions are put forward to the nuclear energy development in China. (authors)

    In recent years, China has made great efforts in energy saving and carbon emission reduction by pushing forward domestic sustainable development along with global climate change mitigation. The efforts have paid off with a dramatic decrease in carbon intensity. Nevertheless, China is still confronted with tough challenges in emission control due to the fast pace of industrialization, large total historical emission and high growth rate of emissions. Therefore, China should give priority to energy saving by improving energy efficiency and sectoral structure adjustment and upgrade, and develop sustainable and renewable energy to optimize energy mix and its carbon content. China should continue to regard significant reduction of energy intensity and carbon intensity as the main objective in the near future, strive to achieve peak emissions around 2030, and realize a relatively sharp emissions reduction by 2050 in order to address climate change to meet the goal of making the warming less than 2°. During the 12th Five Year Plan (FYP), China will further strengthen measures to control the amount of energy consumption, establish a statistics, accounting and evaluation system of carbon emissions, and promote a market-based carbon emissions trading mechanism to facilitate the low-carbon transformation of China's economy. - Highlights: ► This paper studies China's strategy for energy development and climate change mitigation. ► We suggest that China should focus on reducing the energy intensity and carbon intensity of GDP, and optimization of energy mix in the near term. ► In the long term, China should achieve the peak emission around 2030, and realize a relative sharp emission reduction by 2050. ► The paper also concludes some important measures which China should take during the 12th Five-Year-Plan (2011–2015).

    1995-05-01

    The Biogas and Landfill Gas Marketing Strategy Group was set up with the objective to advise EU-DG 17 (THERMIE/OPET) on the dissemination strategies for biogas and landfill gas (LFG), a subsector of the Renewable Energy Sector (RES). The Marketing Strategy Group has identified market barriers and users' needs in the biogas and LFG subsector. Subsequently, the group evaluated successful instruments/methods to overcome these market barriers and to satisfy the users' needs. The group investigated the feasibility of transposing these instruments/success stories to other countries. The work of the Marketing Strategy Group resulted in proposals for future dissemination of biogas and LFG technology. After a short introduction into LFG technology and the LFG market, this document describes barriers to landfill gas technology dissemination and gives some examples about how to overcome them. This results in recommendations on a strategy for dissemination of LFG technology and expanding LFG markets. The document is mainly based on experience gained in the United Kingdom, Italy and the Netherlands

    As the PV industry matures, successful risk management practices will become more imperative to ensure investor confidence, control costs, and facilitate further growth. This report discusses several key aspects of risk management during the commercial- and utility-scale project life cycle, from identification of risks, to the process of mitigating and allocating those risks among project parties, to transferring those risks through insurance. The report also explores novel techniques in PV risk management, options to offload risks onto the capital markets, and innovative insurance policies (namely warranty policies) that address risks unique to the PV sector. One of the major justifications for robust risk management in the PV industry is the cost-reduction opportunities it affords. If the PV industry can demonstrate the capability to successfully manage its risks, thereby inspiring confidence in financiers, it may be able to obtain a lower cost of capital in future transactions. A lower cost of capital translates to a lower cost of energy, which will in turn enhance PV?s competitiveness at a time when it will have to rely less on subsidies to support its market penetration.

  12. Maximum wind energy extraction strategies using power electronic converters

    Science.gov (United States)

    Wang, Quincy Qing

    2003-10-01

    This thesis focuses on maximum wind energy extraction strategies for achieving the highest energy output of variable speed wind turbine power generation systems. Power electronic converters and controls provide the basic platform to accomplish the research of this thesis in both hardware and software aspects. In order to send wind energy to a utility grid, a variable speed wind turbine requires a power electronic converter to convert a variable voltage variable frequency source into a fixed voltage fixed frequency supply. Generic single-phase and three-phase converter topologies, converter control methods for wind power generation, as well as the developed direct drive generator, are introduced in the thesis for establishing variable-speed wind energy conversion systems. Variable speed wind power generation system modeling and simulation are essential methods both for understanding the system behavior and for developing advanced system control strategies. Wind generation system components, including wind turbine, 1-phase IGBT inverter, 3-phase IGBT inverter, synchronous generator, and rectifier, are modeled in this thesis using MATLAB/SIMULINK. The simulation results have been verified by a commercial simulation software package, PSIM, and confirmed by field test results. Since the dynamic time constants for these individual models are much different, a creative approach has also been developed in this thesis to combine these models for entire wind power generation system simulation. An advanced maximum wind energy extraction strategy relies not only on proper system hardware design, but also on sophisticated software control algorithms. Based on literature review and computer simulation on wind turbine control algorithms, an intelligent maximum wind energy extraction control algorithm is proposed in this thesis. This algorithm has a unique on-line adaptation and optimization capability, which is able to achieve maximum wind energy conversion efficiency through

The relative impact of targeting the very young and the very old for vaccination was weakened by their relative inactivity, thus giving evidence of the lack of impact of vaccinating these two groups on the overall transmissibility of the disease in the community. This further underscores the need for morbidity-based strategy to prevent elderly mortality.

    2002-01-01

    In the competitive industrial environment it is essential that cost of the product is kept at the minimum possible. Energy conservation is an important aspect in achieving this as energy is one of the key recourses for growth and survival of industry. The process of heavy water production being very complex and energy intensive, Heavy Water board has given a focussed attention for initiating various measures for reducing the specific energy consumption in all the plants. The initiative resulted in substantial reduction in specific energy consumption and brought in savings in cost. The cumulative reduction of specific energy consumption has been over 30% over the last seven years and the total savings for the last three years on account of the same has been about Rs. 190 crore. The paper describes the strategies adopted in the heavy water plants for effecting the above achievements. The paper covers the details of some of the energy saving schemes carried out at different heavy water plants through case studies. The case studies of schemes implemented at HWPs are general in nature and is applicable for any other industry. The case studies cover the modifications with re-optimisation of the process parameters, improvements effected in utility units like refrigeration and cooling water systems, improvements in captive power plant cycle and improved recycle scheme for water leading to reduced consumptions. The paper also mentions the innovative ammonia absorption refrigeration with improved coefficient of performance and HWB's efforts in development of the system as an integrated unit of the ammonia water deuterium exchange process for heavy water production. HWB also has taken up R and D on various other schemes for improvements in energy consumption for future activities covering utilisation of low grade energy for generation of refrigeration. (author)

  16. Natural gas supply strategies for European energy market actors

    International Nuclear Information System (INIS)

    Girault, Vincent

    2007-06-01

    The liberalization of the European energy markets leads to the diversification of supplies. Hence, we analyse the natural gas importation problem in a power producer point of view. Upstream and downstream natural gas markets are concentrated. In this oligopoly context, our topic is to focus on strategies which modify natural gas sourcing price. This by studying the surplus sharing on the natural gas chain. A European firm can bundle gas and electricity outputs to increase its market share. Therefore, a bundling strategy of a power producer in competition with a natural gas reseller on the final European energy market increases upstream natural gas price. Bundling also acts as a raising rival cost strategy and reduces the rivals' profit. Profits opportunities incite natural gas producers to enter the final market. Vertical integration between a natural gas producer and a European gas reseller is a way, for producers, to catch end consumer surplus. Vertical integration results in the foreclosure of the power producer on the upstream natural gas market. To be active on the natural gas market, the power producer could supply bundles. But, this strategy reallocates the rent. The integrated firm on natural gas gets the rent of electricity market in expenses of the power producer. Then, a solution for the power producer is to supply gas and electricity as complements. Then, we consider a case where vertical integration is not allowed. Input price discrimination by a monopolist leads to a lower natural gas price for the actor which diversifies its supplying sources. Furthermore, a bundling strategy increases the gap between the price proposed to the firm which also diversify its output and the firm which is fully dependent from the producer to supply natural gas on final market.

    1998-12-01

    This report evaluates residential ventilation systems for the U.S. Environmental Protection Agency's (EPA's) ENERGY STAR{reg_sign} Homes program and recommends mechanical ventilation strategies for new, low-infiltration, energy-efficient, single-family, ENERGY STAR production (site-built tract) homes in four climates: cold, mixed (cold and hot), hot humid, and hot arid. Our group in the Energy Analysis Department at Lawrence Berkeley National Lab compared residential ventilation strategies in four climates according to three criteria: total annualized costs (the sum of annualized capital cost and annual operating cost), predominant indoor pressure induced by the ventilation system, and distribution of ventilation air within the home. The mechanical ventilation systems modeled deliver 0.35 air changes per hour continuously, regardless of actual infiltration or occupant window-opening behavior. Based on the assumptions and analysis described in this report, we recommend independently ducted multi-port supply ventilation in all climates except cold because this strategy provides the safety and health benefits of positive indoor pressure as well as the ability to dehumidify and filter ventilation air. In cold climates, we recommend that multi-port supply ventilation be balanced by a single-port exhaust ventilation fan, and that builders offer balanced heat-recovery ventilation to buyers as an optional upgrade. For builders who continue to install forced-air integrated supply ventilation, we recommend ensuring ducts are airtight or in conditioned space, installing a control that automatically operates the forced-air fan 15-20 minutes during each hour that the fan does not operate for heating or cooling, and offering ICM forced-air fans to home buyers as an upgrade.

Between 1982 and 2002, natural gas consumption in Canada rose by 96 per cent while exports increased by 396 per cent. Crude oil consumption increased by 29 per cent, while exports rose by 595 per cent. Government practices have tended towards extracting and exporting resources as quickly as possible with no consideration to resource availability for future generations. In addition, much of the value of Canadian resources has been given to private corporations. The environment has been damaged in order to enable faster extraction, and First Nations, employees, and communities have been placed at the mercy of corporations and international markets. Canada's unique cultural and societal arrangements have not been protected. Four principles to address these concerns were presented: (1) managing non-renewable resources as responsible stewards and conserving their economic availability for future generations; (2) ensuring that the benefits from fossil fuels are invested in other forms of capital that will ensure the future prosperity and energy security of Canada; (3) ensuring that the extraction and use of resources has minimal impacts on the planet and (4) a re-direction of the proceeds from resource exploitation towards education, social and health services, land claims and land use settlements, and the elimination of poverty among First Nations people. It was suggested that energy-related jobs and workers should be protected through the development of an industrial strategy which includes investment in renewable energy development and re-training programs for workers. Consistent depoliticized policies are needed to reduce the impact on low-income Canadians of free-market price swings and the unavoidable costs of environmental protection. It was

    Environmental concerns and rising fossil fuel prices have prompted rapid development in the renewable energy sector. Wind energy, in particular, has become increasingly popular in the United States. However, the intermittency of available wind energy makes it difficult to integrate wind energy into the power grid. Thus, the expansion and successful implementation of wind energy requires accurate wind resource assessments and wind power forecasts. The actual power produced by a turbine is affected by the wind speeds and turbulence levels experienced across the turbine rotor disk. Because of the range of measurement heights required for wind power estimation, remote sensing devices (e.g., lidar) are ideally suited for these purposes. However, the volume averaging inherent in remote sensing technology produces turbulence estimates that are different from those estimated by a sonic anemometer mounted on a standard meteorological tower. In addition, most lidars intended for wind energy purposes utilize a standard Doppler beam-swinging or Velocity-Azimuth Display technique to estimate the three-dimensional wind vector. These scanning strategies are ideal for measuring mean wind speeds but are likely inadequate for measuring turbulence. In order to examine the impact of different lidar scanning strategies on turbulence measurements, a WindCube lidar, a scanning Halo lidar, and a scanning Galion lidar were deployed at the Southern Great Plains Atmospheric Radiation Measurement (ARM) site in Summer 2013. Existing instrumentation at the ARM site, including a 60-m meteorological tower and an additional scanning Halo lidar, were used in conjunction with the deployed lidars to evaluate several user-defined scanning strategies. For part of the experiment, all three scanning lidars were pointed at approximately the same point in space and a tri-Doppler analysis was completed to calculate the three-dimensional wind vector every 1 second. In another part of the experiment, one of

  1. Energy Demands and Efficiency Strategies in Data Center Buildings

    Information technology (IT) is becoming increasingly pervasive throughout society as more data is digitally processed, stored, and transferred. The infrastructure that supports IT activity is growing accordingly, and data center energy demands haveincreased by nearly a factor of four over the past decade. Data centers house IT equipment and require significantly more energy to operate per unit floor area thanconventional buildings. The economic and environmental ramifications of continued data center growth motivate the need to explore energy-efficient methods to operate these buildings. A substantial portion of data center energy use is dedicated to removing the heat that is generated by the IT equipment. Using economizers to introduce large airflow rates of outside air during favorable weather could substantially reduce the energy consumption of data center cooling. Cooling buildings with economizers is an established energy saving measure, but in data centers this strategy is not widely used, partly owing to concerns that the large airflow rates would lead to increased indoor levels of airborne particles, which could damage IT equipment. The environmental conditions typical of data centers and the associated potential for equipment failure, however, are not well characterized. This barrier to economizer implementation illustrates the general relationship between energy use and indoor air quality in building design and operation. This dissertation investigates how building design and operation influence energy use and indoor air quality in data centers and provides strategies to improve both design goals simultaneously.As an initial step toward understanding data center air quality, measurements of particle concentrations were made at multiple operating northern California data centers. Ratios of measured particle concentrations in conventional data centers to the corresponding outside concentrations were significantly lower than those reported in the literature

  2. Energy strategy would slow coal's growth, says DOE

    The National Energy Strategy (NES) recently announced by the Bush Administration would slow the growth in use of coal by hundreds of millions of tons of coal by hundreds of millions of tons after 2000, according to the Department of Energy's (DOE) own figures. If today's policies are continued, coal consumption will nearly triple by 2030. Current annual consumption of more than 900 million tons (19 quadrillion Btus) would rise to 1,550 million tons in 2010 and to nearly 2,600 million tons by 2030. Coal's share of electricity generation, now about 55%, would grow to 75% by 2030 under the current policy base assumptions of the DOE. The NES, however, projects that surge of nuclear power plant construction will stem the growth of coal use. The strategy would still increase coal use, from 19 quadrillion Btus today to about 28 quads in 2010, but to only 32 quads by 2030. By 2030, coal would account for less than 50% of electricity generation under the NES. Total clean coal technologies capacity is substantially lower under the NES scenario case than under the clean coal actions alone. The strategy also contains good news for the coal industry in the short run. It holds out two main goals for coal policy: maintaining coal's competitiveness while meeting environmental, health and safety requirements; and creating a favorable export climate for US coal and coal technology

  3. Load Reduction, Demand Response and Energy Efficient Technologies and Strategies

    2008-11-19

    The Department of Energy’s (DOE’s) Pacific Northwest National Laboratory (PNNL) was tasked by the DOE Office of Electricity (OE) to recommend load reduction and grid integration strategies, and identify additional demand response (energy efficiency/conservation opportunities) and strategies at the Forest City Housing (FCH) redevelopment at Pearl Harbor and the Marine Corps Base Hawaii (MCBH) at Kaneohe Bay. The goal was to provide FCH staff a path forward to manage their electricity load and thus reduce costs at these FCH family housing developments. The initial focus of the work was at the MCBH given the MCBH has a demand-ratchet tariff, relatively high demand (~18 MW) and a commensurate high blended electricity rate (26 cents/kWh). The peak demand for MCBH occurs in July-August. And, on average, family housing at MCBH contributes ~36% to the MCBH total energy consumption. Thus, a significant load reduction in family housing can have a considerable impact on the overall site load. Based on a site visit to the MCBH and meetings with MCBH installation, FCH, and Hawaiian Electric Company (HECO) staff, recommended actions (including a "smart grid" recommendation) that can be undertaken by FCH to manage and reduce peak-demand in family housing are made. Recommendations are also made to reduce overall energy consumption, and thus reduce demand in FCH family housing.

  4. Reassessing a proposed low-energy strategy for the UK

    1999-01-01

    Predictions, as made in Leach et al. (A low-energy strategy for the United Kingdom. Science Reviews Ltd., Austria: International Institute for Environment and Development, 1979.) have been compared with actual values for subsequent years. Their disparities are discussed, together with the associated lessons. It would have been unreasonable to expect the 1979 predictive procedure to anticipate the 'dash for gas', but it can be realised in retrospect that greater emphasis should have been placed on the likely increasing concern (of successive governments) with environmental protection. In any strategy, the main mechanism (within a government's control) to achieve energy thrift is to raise the unit prices for (i) all fossil fuels and electricity derived from them and especially for (ii) polluting fuels for private cars and aircraft. These measures would simultaneously reduce the overall rate of environmental degradation. There should also be more introductory subsidies, provided by the state, for the implementation of all energy-thrift measures and equipment (e.g. combined heat-and-power plant), that satisfy the criterion of achieving a pay-back period of less than 7 years.

    1994-01-01

    This paper describes an empirical method for estimating the effect of expected prices on energy demand. Data for expected oil prices are compiled from forecasts for real oil prices. The effect of expectations on energy demand is simulated with an expectation variable that proxies the return on investment for energy efficient capital. Econometric results indicate that expected prices have a significant effect on energy demand in the US between 1975 and 1989. A model built from the econometric results indicates that the way in which consumers anticipate changes in energy prices that are generated by a carbon tax affects the quantity of emissions abated by the tax. 14 refs., 4 figs., 1 tab

    This paper explores the relationship between the diversification of sources of imported oil and energy security of oil-importing countries. It examines the importance of diversification policy for oil importers, explains why oil importers implement oil diversification policy, and contextualizes the oil import diversification strategy in the overall energy security policy of oil importers. The paper analyzes the factors and the contexts that affect the level of importance assigned to oil import diversification policy in oil-importing countries, and the limitations that may affect the successful implication of oil import diversification policy. The examples are drawn from the world's top three oil importers, the United States, Japan, and China. The policymakers in these and other oil-importing countries place much importance on energy security. The diversification of oil import sources is used as one of the strategies to enhance energy security in oil-importing countries. This paper is important for policymakers in oil-importing countries as it provides them with a qualitative conceptual framework with which to evaluate the need to diversify their countries' sources of imported oil, and with which to identify the likely limitations to the successful implementation of oil import diversification policy.

    The paper aims at identifying and assessing the revenues and costs incurred by various modernization and modernization-development strategies for a power plant in order to optimize the electric and thermal energy are produced and to conduct a sensitivity analysis of the main performance indicators. The Romanian energy system and the energy market have gone a long transition way, from the vertically integrated model, the responsibility for the delivery of the electricity comes exclusively to a state monopoly, to a decentralized system, characterized by the decentralization of production and transport, respectively distribution activities. Romania chose the liberal market model where the relations between the actors in the market - producers and suppliers free to make sales and purchase transactions for electrical energy - are mostly governed by contracts, which may be either bilaterally negotiated or are already regulated. Therefore, the importance of understanding the development trend of the Romanian energy market lies in its economic effects upon the solutions which could be adopted for the evolution of the cogeneration power plant in question.

  8. Hydrogen energy strategies and global stability and unrest

    2004-01-01

    This paper focuses on hydrogen energy strategies and global stability and unrest. In order to investigate the strategic relationship between these concepts, two empirical relations that describe the effects of fossil fuels on global stability and global unrest are developed. These relations incorporate predicted utilization ratios for hydrogen energy from non-fossil fuels, and are used to investigate whether hydrogen utilization can reduce the negative global effects related to fossil fuel use, eliminate or reduce the possibilities of global energy conflicts, and contribute to achieving world stability. It is determined that, if utilization of hydrogen from non-fossil fuels increases, for a fixed usage of petroleum, coal and natural gas, the level of global unrest decreases. However, if the utilization ratio of hydrogen energy from non-fossil fuels is lower than 100%, the level of global stability decreases as the symptoms of global unrest increase. It is suggested that, to reduce the causes of global unrest and increase the likelihood of global stability in the future, hydrogen energy should be widely and efficiently used, as one component of plans for sustainable development.

    The paper presents the results of a study carried out from a environmental protection point of view by a multi-branch team of 25 Romanian experts. A general block diagram type procedure of elaborating a national energy-environment strategy has been proposed. The sustainable development has been chosen as an overall evaluating criterion involving the fulfillment of the following conditions: the environmental protection; the best use of material, financial and human resources; the promotion of equity. For strategic objectives have been identified: increasing energy efficiency; reconsidering the existing generation capacities and their future trends; diversifying the primary resources and their suppliers; reducing the energy impacts on the environment, and three support objectives: creation of an economic and financial framework market oriented; setting up a regulatory system for efficient market operation; establishing an institutional framework for the energy sector. The fundamental concepts promoted and recommended to be used have been: sustainable development, energy efficiency, competition, integrated resources planning, demand-side management.

    Full Text Available A heavy-duty parallel hybrid electric truck is modeled, and its optimal energy control is studied in this paper. The fundamental architecture of the parallel hybrid electric truck is modeled feed-forwardly, together with necessary dynamic features of subsystem or components. Dynamic programming (DP technique is adopted to find the optimal control strategy including the gear-shifting sequence and the power split between the engine and the motor subject to a battery SOC-sustaining constraint. Improved control rules are extracted from the DP-based control solution, forming near-optimal control strategies. Simulation results demonstrate that a significant improvement on the fuel economy can be achieved in the heavy-duty vehicle cycle from the natural driving statistics.

    The Nineteenth Annual Illinois Energy Conference was held in Chicago, Illinois November 1991. It was organized by the Energy Resources Center, University of Illinois at Chicago with major support provided by the US Environmental Protection Agency, the US Department of Energy, the Illinois Commerce Commission, the Illinois Department of Energy and Natural Resources, and the Citizens Council on Energy Resources. The conference program was developed by a planning committee who drew upon Illinois energy and environmental specialists from the major sectors including energy industries, environmental organizations, research universities, utility companies, federal, state and local government agencies, and public interest groups. The members of the planning committee were brought together for a full-day session where they were asked to assess the political, economic, and social impacts of the proposed National Energy Strategy as it relates to Illinois and the Midwest region. Within this context, the planning committee identified several major issues including: (1) Is the proposed plan a balanced strategy; (2) What are the NES impacts on the transportation sector; (3) What are the opportunities for improved efficiency in the Electric Utility Sector; and (4) What is the role of advanced research and development.

    RLA Consulting (RLA) has been retained by the State of Hawaii Department of Business, Economic Development and Tourism (DBEDT) to conduct a Renewable Energy Resource Assessment and Development Program. This three-phase program is part of the Hawaii Energy Strategy (HES), which is a multi-faceted program intended to produce an integrated energy strategy for the State of Hawaii. The purpose of Phase 1 of the project, Development of a Renewable Energy Resource Assessment Plan, is to better define the most promising potential renewable energy projects and to establish the most suitable locations for project development in the state. In order to accomplish this goal, RLA has identified constraints and requirements for renewable energy projects from six different renewable energy resources: wind, solar, biomass, hydro, wave, and ocean thermal. These criteria were applied to areas with sufficient resource for commercial development and the results of Phase 1 are lists of projects with the most promising development potential for each of the technologies under consideration. Consideration of geothermal energy was added to this investigation under a separate contract with DBEDT. In addition to the project lists, a monitoring plan was developed with recommended locations and a data collection methodology for obtaining additional wind and solar data.

    Dyner, I.

    2000-01-01

    The energy field has been dominated by 'hard' modelling approaches by researchers from engineering and economics discipline. The recent trend towards a more liberalised environment moves away from central planning to market-based resource allocation, leading to the creation and use of strategic tools, with much 'softer' specifications, in the 'system-thinking' tradition. This paper presents the use of system dynamics in a generalised way, to provide a platform for integrated energy analysis. Issues of modularity and policy evolution are important in the design of the modelling platform to facilitate its use, and reuse. Hence the concepts of a platform, rather than a model, has to be implemented in a coherent way if it is to provide sustained value for ongoing support to both government policy and corporate strategy.

    2011-01-01

    Since the introduction of market-oriented economy in 1986, Vietnam has made noticeable socio-economic progress. In this progress, the energy sector has played a vital role. This role is likely to deepen in the years to come as Vietnam strives to achieve even higher levels in economic progress. Such deepening in the role of energy, this paper argues, will heighten concerns about the security of energy supply, and economic, environmental, social and political consequences. In order to address these issues, Vietnam has over the last decade, developed a suite of energy policies. A deeper review of these policies suggests that they are typified by economic-growth orientation, exclusive focus on a single-sector or single issue, and largely neglect the significance of cross-sectoral and cross-thematic issues arising from the interdependencies between energy, economy, and the polity at large. The existing energy policy settings are, therefore, unlikely to be able to provide a satisfactory redress to the challenges noted above. This paper provides an overview of the current energy policies with a view to identify areas where further policy effort is needed in order to facilitate a sustainable development of the Vietnamese energy sector. - Highlights: → Identifying challenges faced by the Vietnamese energy sector. → Analyzing limitations of the existing energy policy settings (policies, strategies and institutions) in addressing these challenges. → Developing recommendations on improving the existing energy policy settings to provide a satisfactory redress for the challenges noted above.

    Offering high efficiency and producing zero emissions Fuel Cells (FCs) represent an excellent alternative to internal combustion engines for powering vehicles to alleviate the growing pollution in urban environments. Due to inherent limitations of FCs which lead to slow transient response, FC-based vehicles incorporate an energy storage system to cover the fast power variations. This paper considers a FC/supercapacitor platform that configures a hard constrained powertrain providing an adverse scenario for the energy management strategy (EMS) in terms of fuel economy and drivability. Focusing on palliating this problem, this paper presents a novel EMS based on the estimation of short-term future energy demand and aiming at maintaining the state of energy of the supercapacitor between two limits, which are computed online. Such limits are designed to prevent active constraint situations of both FC and supercapacitor, avoiding the use of friction brakes and situations of non-power compliance in a short future horizon. Simulation and experimentation in a case study corresponding to a hybrid electric bus show improvements on hydrogen consumption and power compliance compared to the widely reported Equivalent Consumption Minimization Strategy. Also, the comparison with the optimal strategy via Dynamic Programming shows a room for improvement to the real-time strategies.

    Renewable energy technology (RET) innovation involves new, improved processes, as well as strategies to accelerate RET development, ranging from breakthroughs with basic technology inventions and improved research, development and deployment (RDD) systems, to improved market mechanisms and commercialisation. In order to achieve RET innovation, a country needs to put in place the right policy approaches, frameworks, governance and policy instruments. This working paper was compiled to assist countries with policy development in order to strengthen renewable energy innovation, primarily through a discussion of design criteria for innovation policy frameworks. The report identifies broad success criteria for innovation policy in the sector and suggests strategic policy approaches to advance RET innovation in the context of constrained options, competition for resources, and national economic development goals. For renewable energy innovation policy regimes to be succeed, they must satisfy two broad criteria: (a) promotion of sustained multi-stakeholder engagement around an achievable, shared vision; and (b) appropriate positioning of a country or region to anticipate and benefit from renewable energy technology flows.

    Cluster analysis of summer and winter discomfort in terms of heat and cold stresses based on 102-year (1901-2002) weather data in China was conducted. Five bioclimate zones were identified. These were compared with the corresponding thermal and solar zoning classifications. Bio-I and Bio-II tended to locate largely within severe cold and cold climates in the north with excellent solar availability (annual clearness index K t generally exceeding 0.5). Bio-III and Bio-IV covered mostly the hot summer and cold winter and mild climate zones. Despite the relatively low K t in winter, passive solar heating should be able to meet a significant proportion of the heating requirements. Bio-V covered the hot summer and warmer winter region, where heat stress and hence cooling requirement dominated. Decreasing trends in the zone-average annual cumulative cold stress during the 102-year period were observed for all five zones. There was, however, no distinct pattern for the heat stress and the changes tended to be more subtle. These indicate that climate change during the 20 th century affected winter discomfort (especially in colder climates in the north) more than the summer discomfort. This could have significant implications for energy use in buildings if such trends persist. (author)

  7. Planetary cores, their energy flux relationship, and its implications

    Integrated surface heat flux data from each planet in our solar system plus over 50 stars, including our Sun, was plotted against each object's known mass to generate a continuous exponential curve at an R-squared value of 0.99. The unexpected yet undeniable implication of this study is that all planets and celestial objects have a similar mode of energy production. It is widely accepted that proton-proton reactions require hydrogen gas at temperatures of about 15 million degrees, neither of which can plausibly exist inside a terrestrial planet. Hence, this paper proposes a nuclear fission mechanism for all luminous celestial objects, and uses this mechanism to further suggest a developmental narrative for all celestial bodies, including our Sun. This narrative was deduced from an exponential curve drawn adjacent to the first and passing through the Earth's solid core (as a known prototype). This trend line was used to predict the core masses for each planet as a function of its luminosity.

    The majority of lightweight rowers undertake acute weight loss prior to competition. Given the competitive advantage afforded to larger, more muscular rowers over their smaller counterparts, the use of moderate, acute weight loss may be justified, at least among larger, leaner athletes who struggle to achieve the specified body mass requirement and have limited potential for further body mass loss via reductions in body fat. The performance implications of moderate acute weight loss appear to be small on the ergometer and may be even less on water, at least when aggressive recovery strategies are adopted between weigh-in and racing. Furthermore, any performance implications of acute weight loss are not exacerbated when such weight loss is undertaken repeatedly throughout the course of a regatta, and may even be eliminated when aggressive recovery strategies are introduced before and after racing. The combination of adequate sodium, fluid and carbohydrate in line with current guidelines results in the best performances. While the performance implications of modest acute weight loss may still need to be considered in regard to competition outcome, chronic body mass strategies may not be without performance implications. This is especially the case for athletes who have very low levels of body fat and/or athletes who decrease their body mass too quickly. Further studies are needed to address the degree of weight loss that can be tolerated with minimal health and/or performance implications, and the optimal time frame over which this should occur. Possible adaptation to the physiological state that accompanies acute weight loss also warrants investigation. Published by the BMJ Publishing Group Limited.

    There must be an end-use orientation to energy planning. What is required therefore is a development-focused end-use-oriented service-directed paradigm such as DEFENDUS. The fundamental cause of India's current oil crisis is the country's unchecked appetite for diesel, kerosene and gasoline due to railway freight being de-emphasized, homes not being electrified and personal transportation being preferred. The DEFENDUS strategy for resolving India's oil crisis is implementing efficiency improvements in the use of petroleum products, shifting passenger traffic from personal vehicles to public transportation, shifting freight traffic from road to rail, and replacing oil with alternative non-oil fuels, particularly biomass-derived fuels. The proposed strategy is a massive programme of home electrification. When all homes are electrified, kerosene becomes unnecessary as an illuminant. Once this is done, the subsidy on diesel can be removed and its price can be brought on par with that of gasoline. The increase of diesel prices would create a favourable environment in which supporting policy measures can be adopted. For the railways to exploit the situation and increase their freight haulage, there must be substantial investments in the improvement of the railways' freight operations. These funds can come from the diversion of the implicit subsidies on kerosene and diesel. This strategy of shifting freight from trucks to rail can reduce drastically the diesel demand in the transport sector. The next component of the strategy consists of the provision of high-efficiency cooking fuels and/or devices in rural and urban areas and would make available large amounts of wood provided that all the firewood being used today for cooking can still be collected. This saved fuelwood can be converted into methanol. If diesel fuel in trucks and buses is replaced with methanol, then the only diesel demand from the transport sector will come from the railways.

    Sustainable development of Chinese economy in 21. century will mainly rely on self-supply of clean energy with indigenous natural resources. The burden of current coal-dominant energy mix and the environmental stress due to energy consumptions has led nuclear power to be an indispensable choice for further expanding electricity generation capacity in China and for reducing greenhouse effect gases emission. The application of nuclear energy in producing substitutive fuels for road transportation vehicles will also be of importance in future China's sustainable energy strategy. This paper illustrates the current status of China's energy supply and the energy demand required for establishing a harmonic and prosperous society in China. In fact China's energy market faces following three major challenges, namely (1) gaps between energy supply and demand; (2) low efficiency in energy utilization, and (3) severe environmental pollution. This study emphasizes that China should implement sustainable energy development policy and pay great attention to the construction of energy saving recycle economy. Based on current forecast, the nuclear energy development in China will encounter a high-speed track. The demand for crude oil will reach 400-450 million tons in 2020 in which Chinese indigenous production will remain 180 million tons. The increase of the expected crude oil will be about 150 million tons on the basis of 117 million tons of imported oil in 2004 with the time span of 15 years. This demand increase of crude oil certainly will influence China's energy supply security and to find the substitution will be a big challenge to Chinese energy industry. This study illustrates an analysis of the market demands to future hydrogen economy of China. Based on current status of technology development of HTGR in China, this study describes a road of hydrogen production with nuclear energy. The possible technology choices in relation to a number of types of nuclear reactors are

    In contrast to Europe and North America, air pollution in Asia is increasing rapidly, resulting in both local air quality problems and higher acidic depositions. In 1989, an east-west group of scientists initiated a multi-institutional research project on Acid Rain and Emissions Reduction in Asia, funded for the past two years by the World Bank and the Asian Development Bank. Phase I, covering 23 countries of Asia, focused on the development of PC-based software called the Regional Air Pollution Information and Simulation Model (RAINS-ASIA). A 94-region Regional Energy Scenario Generator was developed to create alternative energy/emission scenarios through the year 2020. A long-range atmospheric transport model was developed to calculate dispersion and deposition of sulfur, based upon emissions from area and large point sources, on a one-degree grid of Asia. The resulting impacts of acidic deposition on a variety of vegetation types were analyzed using the critical loads approach to test different emissions management strategies, including both energy conservation measures and sulfur abatement technologies. 14 refs., 7 figs

    An unbiased strategy to search for the global and local minimal energy structures of free standing nanoclusters is presented. Our objectives are twofold: to find a diverse set of low lying local minima, as well as the global minimum. To do so, we use massively the fast inertial relaxation engine algorithm as an efficient local minimizer. This procedure turns out to be quite efficient to reach the global minimum, and also most of the local minima. We test the method with the Lennard-Jones (LJ) potential, for which an abundant literature does exist, and obtain novel results, which include a new local minimum for LJ13 , 10 new local minima for LJ14 , and thousands of new local minima for 15≤N≤65. Insights on how to choose the initial configurations, analyzing the effectiveness of the method in reaching low-energy structures, including the global minimum, are developed as a function of the number of atoms of the cluster. Also, a novel characterization of the potential energy surface, analyzing properties of the local minima basins, is provided. The procedure constitutes a promising tool to generate a diverse set of cluster conformations, both two- and three-dimensional, that can be used as an input for refinement by means of ab initio methods.

    materials strategy, based upon additional events and information, by the end of 2011.DOE's strategy with respect to critical materials rests on three pillars. First, diversified global supply chains are essential. To manage supply risk, multiple sources of materials are required. This means taking steps to facilitate extraction, processing and manufacturing here in the United States, as well as encouraging other nations to expedite alternative supplies. In all cases, extraction and processing should be done in an environmentally sound manner. Second, substitutes must be developed. Research leading to material and technology substitutes will improve flexibility and help meet the material needs of the clean energy economy. Third, recycling, reuse and more efficient use could significantly lower world demand for newly extracted materials. Research into recycling processes coupled with well-designed policies will help make recycling economically viable over time.The scope of this report is limited. It does not address the material needs of the entire economy, the entire energy sector or even all clean energy technologies. Time and resource limitations precluded a comprehensive scope. Among the topics that merit additional research are the use of rare earth metals in catalytic converters and in petroleum refining. These topics are discussed briefly in Chapter 2.

    Denmark is arguably the most energy secure and sustainable country in the Organization of Economic Cooperation and Development (OECD). The country has reduced its dependence on foreign sources of energy to zero and become self-sufficient in its own energy production and use, offering important lessons for other nations around the world. This study explores the core of Denmark's successful approach: a commitment to energy efficiency, prolonged taxes on energy fuels, electricity, and carbon dioxide, and incentives for combined heat and power (CHP) and wind turbines. Through these commitments, the study shows how Denmark transitioned from being almost 100 percent dependent on imported fuels such as oil and coal for their power plants in 1970 to becoming a net exporter of fuels and electricity today. The country leads the world in terms of exportation of wind energy technology, with a hold on roughly one-third of the world market for wind turbines. It was able to phase out the use of virtually all oil-fired power plants in less than five years and implemented a progressive moratorium on future coal-fired power plants in the 1990s. Their most recent strategy seeks to achieve 30 percent of total energy supply from renewable energy by 2025. - Highlights: • Denmark is arguably the most energy secure and sustainable country in the OECD. • This study explores the core of Denmark's successful approach. • Denmark phased out oil-fired power plants in less than five years. • It also implemented a progressive moratorium on coal-fired power plants

  20. Power generation assets. Energy constraints, upper bounds and hedging strategies

    Enge, Thomas

    2010-09-20

    The overall topic of this thesis is the valuation of power generation assets under energy and risk constraints. Our focus is on the modeling aspect i.e. to find the right balance between accuracy and computational feasibility. We define a new not yet investigated unit commitment problem that introduces an energy constraint to a thermal power plant. We define a continuous stochastic dynamic program with a nested mixed integer program (MIP). We introduce a fast implementation approach by replacing the MIP with an efficient matrix calculation and use principal component analysis to reduce the number of risk factors. We also provide a fast heuristic valuation approach for comparison. As both models can only provide lower bounds of the asset value, we investigate the theory of upper bounds for a proper validation of our power plant results. We review the primal dual algorithm for swing options by Meinshausen and Hambly and in particular clarify their notation and implementation. Then we provide an extension for swing options with multiple exercises at the same stage that we developed together with Prof. Bender, University of Braunschweig. We outline Prof. Bender's proof and describe the implementation in detail. Finally we provide a risk analysis for our thermal power plant. In particular we investigate strategies to reduce spot price risk to which power plants are significantly exposed. First, we focus on the measurement of spot price risk and propose three appropriate risk figures (Forward delta as opposed to Futures delta, synthetic spot delta and Earnings-at-Risk) and illustrate their application using a business case. Second we suggest risk mitigation strategies for both periods, before and in delivery. The latter tries to alter the dispatch policy i.e. pick less risky hours and accept a (desirably only slightly) smaller return. We introduce a benchmark that weighs risk versus return and that we will call EaR-efficient option value. We propose a mitigation

  1. Energy management action plan: Developing a strategy for overcoming institutional barriers to municipal energy conservation

    Energy Technology Data Exchange (ETDEWEB)

    1992-12-31

    Energy offices working to improve efficiency of local government facilities face not only technical tasks, but institutional barriers, such as budget structures that do not reward efficiency, a low awareness of energy issues, and purchasing procedures based only on minimizing initial cost. The bureau, in working to remove such barriers in San Francisco, has identified 37 institutional barriers in areas such as operations & maintenance, purchasing, and facility design; these barriers were then reorganized into three groupings-- policy & attitudes, budget & incentives, and awareness & information-- and mapped. This map shows that the barriers mutually reinforce each other, and that a holistic approach is required for permanent change. The city`s recreation & parks department was used as a model department, and information about facility energy use was compiled into a departmental energy review. Staff interviews showed how barriers affect conservation. The bureau then generated ideas for projects to remove specific barriers and rated them according to potential impact and the resources required to implement them. Four of the six projects selected focused on maintenance staff: a cost- sharing lighting retrofit program, a boiler efficiency program, a departmental energy tracking system, and a budgetary incentive program for conservation. The other two projects are city-wide: promotion of a new term contract supplying energy-efficient light materials, and publication/distribution of ENERGY NEWS newsletter. A general methodology, the EMAP Strategy Guide, has been created to assist other energy offices in developing EMAPs.

  2. Markets for energy efficiency: Exploring the implications of an EU-wide 'Tradable White Certificate' scheme

    2008-01-01

    Recent developments in European energy policy reveal an increasing interest in implementing the so-called 'Tradable White Certificate' (TWC) schemes to improve energy efficiency. Based on three evaluation criteria (cost-effectiveness, environmental effectiveness and distributional equity) this paper analyses the implications of implementing a European-wide TWC scheme targeting the household and commercial sectors. Using a bottom-up model, quantitative results show significant cost-effective potentials for improvements (ca. 1400 TWh in cumulative energy savings by 2020), with the household sector, gas and space heating representing most of the TWC supply in terms of eligible sector, fuel and energy service demand, respectively. If a single market price of negative externalities is considered, a societal cost-effective potential of energy savings above 30% (compared to the baseline) is observed. In environmental terms, the resulting greenhouse gas emission reductions are around 200 Mt CO 2-eq by 2010, representing nearly 60% of the EU-Kyoto-target. From the qualitative perspective, several embedded ancillary benefits are identified (e.g. employment generation, improved comfort level, reduced 'fuel poverty', security of energy supply). Whereas an EU-wide TWC increases liquidity and reduces the risks of market power, autarky compliance strategies may be expected in order to capture co-benefits nationally. Cross subsidies could occur due to investment recovery mechanisms and there is a risk that effects may be regressive for low-income households. Assumptions undertaken by the modelling approach strongly indicate that high effectiveness of other policy instruments is needed for an EU-wide TWC scheme to be cost-effective

    China's annual energy demand is expected to amount to 3360 million tons of oil equivalent (toe) in 2050, the target year for the nation's economic development to reach the level of medium-developed countries in the middle of this century. The future energy supply, doubtless to go through a substantial increase and necessary mix shift with potential significant environmental impacts, will continue to rely on the domestic sources with coal-dominance but diversified mixes, in which nuclear power makes up a reasonable share. The large-scale development of nuclear energy is essential and promising, with the total installed capacity expectedly over 200-300 GW around 2050, and will be an effective response measure to mitigate the energy-derived environmental pollution and guarantee the national energy security. China is a developing country with the largest population in the world. The energy production had achieved remarkable progress over the last half century, particularly since the initiatives of reform and opening to the outside world in the late 1970s, and energy demand to fuel the continued socio-economic growth has been largely met. The current energy consumption of China is 896 Mtoe (China Stat. Abs. (2001) 130), accounting for about 11% of the world's total, the second largest energy consumer in the globe. However, the energy supply will face even tougher challenges in terms of demand increase, mix shift and potential environmental impacts to be posed by a sustained fast-growing economy in light of China's blueprint for future development. With the switch-over from the centrally planned economy to the socialist market economy and the gradual integration of China's energy trade into the international markets, the imported crude oil in 2000 amounted to 70.265 Mt (Int. Petrol. Econ. 9 (2000) 5), about 3.5% of the global petroleum trade, the long-term energy security for China would have great regional and global implications. It is, therefore, of great significance

    In Task 2, the authors establish a baseline for evaluating energy use in Hawaii, and examine key energy and economic indicators. They provide a detailed look at fossil energy imports by type, current and possible sources of oil, gas and coal, quality considerations, and processing/transformation. They present time series data on petroleum product consumption by end-use sector, though they caution the reader that the data is imperfect. They discuss fuel substitutability to identify those end-use categories that are most easily switched to other fuels. They then define and analyze sequential scenarios of fuel substitution in Hawaii and their impacts on patterns of demand. They also discuss energy security--what it means to Hawaii, what it means to neighboring economies, whether it is possible to achieve energy security. 95 figs., 48 tabs.

    2010-11-01

    Full Text Available As ally movements become an increasingly prevalent element of social justice efforts, research is needed that illuminates effective strategies to initially engage members of privileged social groups in anti-oppression work. This study presents descriptive findings regarding ally engagement strategies and barriers from a qualitative study of a particular ally movement – male anti-violence against women activism. Twenty-seven men who recently initiated involvement in an organization or event dedicated to ending sexual or domestic violence were interviewed regarding their perceptions of effective approaches to reaching and engaging other men in anti-violence work. Participants viewed tailored engagement strategies that tap into existing social networks, that allow men to see themselves reflected in anti-violence movements, and that help men make personal, emotional connections to the issue of violence as most effective. Implications for engaging men in the project of ending violence against women, and for ally movements more generally are discussed.

  6. Challenges and opportunities for implementing sustainable energy strategies in coastal communities of Baja California Sur, Mexico

    Etcheverry, Jose R.

    This dissertation explores the potential of renewable energy and efficiency strategies to solve the energy challenges faced by the people living in the biosphere reserve of El Vizcaino, which is located in the North Pacific region of the Mexican state of Baja California Sur. This research setting provides a practical analytical milieu to understand better the multiple problems faced by practitioners and agencies trying to implement sustainable energy solutions in Mexico. The thesis starts with a literature review (chapter two) that examines accumulated international experience regarding the development of renewable energy projects as a prelude to identifying the most salient implementation barriers impeding this type of initiatives. Two particularly salient findings from the literature review include the importance of considering gender issues in energy analysis and the value of using participatory research methods. These findings informed fieldwork design and the analytical framework of the dissertation. Chapter three surveys electricity generation as well as residential and commercial electricity use in nine coastal communities located in El Vizcaino. Chapter three summarizes the fieldwork methodology used, which relies on a mix of qualitative and quantitative research methods that aim at enabling a gender-disaggregated analysis to describe more accurately local energy uses, needs, and barriers. Chapter four describes the current plans of the state government, which are focused in expanding one of the state's diesel-powered electricity grids to El Vizcaino. The Chapter also examines the potential for replacing diesel generators with a combination of renewable energy systems and efficiency measures in the coastal communities sampled. Chapter five analyzes strategies to enable the implementation of sustainable energy approaches in El Vizcaino. Chapter five highlights several international examples that could be useful to inform organizational changes at the federal

    Health systems are facing significant pressure to either implement health information technology (HIT) systems that have "certified" electronic health record applications and that fulfill the federal government's definition of "meaningful use" or risk substantial financial penalties in the near future. To this end, hospitals have adopted one of three strategies, described as "best of breed," "best of suite," and "single vendor," to meet organizational and regulatory demands. The single-vendor strategy is used by the simple majority of U.S. hospitals, but is it the most effective mode for achieving full implementation? Moreover, what are the implications of adopting this strategy for achieving meaningful use? The simple answer to the first question is that the hospitals using the hybrid best of suite strategy had fully implemented HIT systems in significantly greater proportions than did hospitals employing either of the other strategies. Nonprofit and system-affiliated hospitals were more likely to have fully implemented their HIT systems. In addition, increased health maintenance organization market penetration rates were positively correlated with complete implementation rates. These results have ongoing implications for achieving meaningful use in the near term. The federal government's rewards and incentives program related to the meaningful use of HIT in hospitals has created an organizational imperative to implement such systems. For hospitals that have not begun systemwide implementation, pursuing a best of suite strategy may provide the greatest chance for achieving all or some of the meaningful use targets in the near term or at least avoiding future penalties scheduled to begin in 2015.

    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

    Energy pricing has been shown to have direct impact on energy demand and hence on energy efficiency. Regulated pricing which is below actual production price encourages inefficient use of energy with sometimes associated environmental problems. The important consideration presently being given to development of energy in an environmentally safe and economically prosperous society implies that energy pricing an play an important role in achieving these objectives

    1996-12-31

    This paper describes the mitigation potential in the Russian energy sector and presents CO{sub 2} - emission scenarios. Based on the Russian energy strategy, energy conservation potential has been estimated and three groups of energy conservation measures have been pointed out. Taking into account the economic development scenarios and the scenarios of energy consumption and energy conservation, future CO{sub 2} emission scenarios for 2000 and 2010 have been prepared. Some important characteristics of these scenarios have been presented and discussed. For the period 2000-2010 annual growth rates for CO{sub 2} emission in the Russian energy sector will not exceed 0.9-1.3 %, and emission levels in 2000 make up - 75-78 %, and in 2010 - 81-88 % of the 1990 level. For the probable scenario the CO{sub 2} emission reducing will make up about 6% and 25% (for the optimistic scenario about 16% and 31%) of CO{sub 2} emission for reference scenario in 2000 and 2010 respectively.

    Abstracts: The Korean government adopted “green growth” in 2008 as an environmentally friendly growth strategy. The energy efficiency of Korea, however, is still relatively low due to the large portion of energy intensive industry (EII) in its manufacturing sector. To improve energy efficiency in Korea, from an EII perspective a new approach has to be taken because restructuring entire industries would take too much time and be too costly. This study aims to emphasize the importance of innovation and analyze the effects of R&D on product and process innovations in EII in Korea. The Probit model is adopted to estimate the effects of eight determinants in the Korea Innovation Survey 2008 data. The results of this study demonstrate that one of the most important determinants, the R&D personnel ratio, has a strong positive effect on both product and process innovation, while another determinant, R&D intensity, only has a strong and positive effect on process innovation in EII. Because of the resulting innovation, energy policies should be enacted to enhance energy efficiency. Thus, the Korean government should keep providing incentives for firms in EII to invest more financial and human resources in their R&D activities. -- Highlights: •We analyze determinants on two innovations in energy intensive industry (EII). •The R&D personnel ratio is effective in product innovation in EII. •Both R&D intensity and R&D personnel are effective in process innovation in EII. •In less EII, R&D variables have positive effects on product and process innovations. •The Korean government should strongly support R&D to improve energy efficiency

    Generally, companies adapt their strategies to a changing environment, a process that often moves faster than the implementation of new policy measures. These strategic reactions are often taken to mitigate risks and to secure a strong position in an increasingly competitive market. Such responses interact with the main policy priorities. It is therefore interesting to understand the interaction between company strategies and policy priorities and to assess whether synergies can be found and whether strategies and policy objectives can be aligned. This study concentrates on gas and electricity companies in Europe's largest markets. The structure of the paper is as follows. Chapter 2 introduces the major changes that have taken place and that have formed the basis of the EU's new energy policy priorities. Chapter 3 presents the strategic responses that followed these major trends. In Chapter 4, specific strategies that companies developed to deal with the changing environment are highlighted and illustrated with examples. Chapter 5 discusses the alignment of company strategies and policy objectives and presents a number of policy recommendations to make use of the companies for reaching policy targets. The final chapter provides the conclusion. A number of appendices are included to provide background to the analyses.

    Women are the main producers of energy in developing countries and households are the main users of energy. Because gender roles and traditions have been largely ignored in energy, the global potential for renewable energy has been negatively affected. However, microcredit lending could fund sustainable development technology. This paper argues that renewable energy, gender roles, and microfinancing should be inherent parts of sustainable economic development programs. The relevant activities of pertinent development organisations and potential synergies are briefly described, the plans for the U.S. National Renewable Energy Laboratory to explore the gender issue are summarised, and the evolution of gender and energy as a field is addressed.

    The paper presents an exhaustive comparison of principal traffic noise models adopted in recent years in developed nations. The comparison is drawn on the basis of technical attributes including source modelling and sound propagation algorithms. Although the characterization of source in terms of rolling and propulsion noise in conjunction with advanced numerical methods for sound propagation has significantly reduced the uncertainty in traffic noise predictions, the approach followed is quite complex and requires specialized mathematical skills for predictions which is sometimes quite cumbersome for town planners. Also, it is sometimes difficult to follow the best approach when a variety of solutions have been proposed. This paper critically reviews all these aspects pertaining to the recent models developed and adapted in some countries and also discusses the strategies followed and implications of these models. - Highlights: • Principal traffic noise models developed are reviewed. • Sound propagation algorithms used in traffic noise models are compared. • Implications of models are discussed.

    World's growing demand for food is driven by population and income growth, dietary changes, and the ever-increasing competition between food, feed and bioenergy challenges food security; meanwhile agricultural expansion and intensification threats the environment by the various detrimental impacts. Researchers have attempted to explore strategies to overcome this grand challenge. One of the promising solutions that have attracted considerable attention recently is to increase the efficiency of food supply chain by reducing food loss and waste (FLW). According to recent studies conducted by Food and Agriculture Organization (FAO), United Nation, almost one third of the food produced for human consumption globally is lost or wasted along the food supply chain. This amount of food discarded manifests a missing, yet potential, opportunity to sustainably enhance both food security and environmental sustainability. However, implementing the strategies and technologies for tackling FLW does not come up as an easy solution since it requires economic incentives, benefit and cost analysis, infrastructure development, and appropriate market mechanism. In this presentation I will provide a synthesis of knowledge on the implications of postharvest food loss/waste prevention to energy and resource conservation, environmental protection, as well as food security. I will also discuss how traditional civil and environmental engineering can contribute to the reduction of postharvest food loss, an important issue of sustainable agriculture.

The production activity has high dependence on the usage of diesel, which influences the quality of the product and the cost of total business. The price fluctuation is one of the reasons for the company to convert the usage of diesel to some energy alternatives. Gas is the best alternative to replace diesel due to some advantages such as price, installation cost, distribution issue, calorie level, and environmental issue. There are some resistances from internal organization emerge in the implementation of the conversion. The alternatives strategy has been explored to reduce the resistances considering the goal of the organization, the actors (department in the company, and the type of resistance using analytical hierarchy process method. The priority strategy is establishing a new division for handling the conversion program and installing the gas facility gradually.

    The global commitment to environmental protection and in particular to reduction of greenhouse gas emissions, Macedonian's dependence on energy imports, as well as the need to secure greater variety and thereby reliability of energy supply undoubtedly impose increased share of renewable energy sources in the final energy consumption. however, in parallel with activities and measures targeting increased share of renewable energy sources, measures and activities to increase energy efficiency of final energy consumption should be pursued. thus, the target share of renewable energy sources in final consumption will be achieved much easily and faster, but the economy's competitiveness will also be improved due to reduced energy costs. in preparation to transpose and implement the Eu legislation (acquis communautaire) on renewable energy sources into the national legislation, the main objective of the present strategy is to provide information on the potential and possible exploitation of renewable energy sources (hereinafter: res) in the republic of macedonia. quantification of such knowledge shall be made by determining the following: - target share in total energy (res target), which is share of energy generated from res in the total energy consumption; - target share of electricity (res electricity target), which is share of electricity generated from res in the total electricity consumption; - manner and dynamics of attaining res target and res electricity target by addressing the following issues: - relevant types of res in the republic of macedonia and their availability; - primary and secondary legislation and institutional set-up ; - financial implications from the establishment of mechanisms to support use of res (feed-in tariffs); - environmental aspects, by means of analysis on possible greenhouse gas emission reduction. furthermore, in the light of secondary legislation on res, the present strategy undertakes relevant analyses aimed to determine: - installed

    Full Text Available The article shows that when people consider differentiated goods or services that differ in price and quality, they exhibit a decision-making bias of ``relative thinking'': relative price differences affect them even when economic theory suggests that only absolute price differences matter. This result is obtained in four different consumption categories. Sometimes subjects are affected only by relative price differences (``full relative thinking'' and sometimes also by absolute price differences (``partial relative thinking''. This behavior has implications for various disciplines, and it is particularly relevant in models dealing with horizontal or vertical differentiation, optimal pricing, competitive strategy, or advertising.

    In food deprivation assays, several different responses have been observed in crustaceans. However, studying energy reserves utilization among more than one species during the same starvation period has not yet been performed, particularly to discern whether the responses are due to intrinsic and/or environmental factors. We hypothesize that decapod species with similar feeding habits have the same strategies in the use of energetic reserves during starvation, even though they inhabit different environments. The aim of this study was to compare the energy reserves mobilization of three decapods species (Cherax quadricarinatus, Palaemon argentinus and Munida gregaria) with similar feeding habits, exposed to similar food deprivation conditions. The crayfish, shrimp and squat-lobster were experimentally kept at continuous feeding or continuous starvation throughout 15 days. Every 3rd day, the midgut gland index (MGI), and the glycogen, lipid and protein contents were measured in the midgut gland (MG) and pleon muscle. Palaemon argentinus mobilized more reserves during starvation, followed by C. quadricarinatus, and the last M. gregaria. The starved shrimps presented low MGI, whereas MG showed a reduction in glycogen (from day 6 to 15), lipid (from day 3 to 15), and protein levels (at day 9 and 15) while in their muscle, lipid reserves decreased at days 3 and 6. In C. quadricarinatus, the most affected parameters in the MG were MGI, glycogen (from day 6 to 15), and lipids (at day 12 and 15). In the MG of M. gregaria only the glycogen was reduced during fasting from 3 to 15 days. Even though the three studied species have similar feeding habitats, we found that their energetic profile utilization is different and it could be explained by the habitat, life span, temperature, organ/tissue, and metabolism of the species. Our results may be useful to understand the several different responses of crustaceans during starvation.

  7. Farmers’ Adaptation Strategies to Climate Change and Their Implications in the Zou Department of South Benin

    Full Text Available Climate change is a global phenomenon. Its impact on agricultural activities in developing countries has increased dramatically. Understanding how farmers perceive climate change and how they adapt to it is very important to the implementation of adequate policies for agricultural and food security. This paper aims to contribute to an understanding of farmers’ adaptation choices, determinants of the adaptation choices and the long-term implications of the adaptation choices. Data were collected from 120 respondents in the Zou Department of Benin. A binary logit model was used to analyze the factors influencing household decisions to adapt to climate change. Multinomial logistic regression analysis was estimated to analyze the factors influencing households’ choice of adaptation strategies to climate change. The results show that farmers have a developed perception of climate change. These changes are translated by rainfall disturbances (rainfall delays, early cessation, bad rainfall distribution etc., shortening of the small dry season, increasing of temperature and sometimes, violent winds. The survey reveals that Benin farmers adopt many strategies in response to climate change. These strategies include “Crop–livestock diversification and other good practices (mulching, organic fertilizer,” “Use of improved varieties, chemical fertilizers and pesticides,” “Agroforestry and perennial plantation” and “Diversification of income-generating activities.” The findings also reveal that most of the respondents use these strategies in combination. From the binary logit model, we know that “farming experience” and “educational level of household head” positively influence adaptation decisions. The result of the multinomial logit analysis shows that farming experience, educational level, farm size and gender have a significant impact on climate change adaptation strategies. Based on in-depth analysis of each strategy, we

    The current energy-related decisionmaking processes that take place during the lifetimes of municipal buildings in San Francisco do not reflect our ideal picture of energy efficiency as a part of staff awareness and standard practice. Two key problems that undermine the success of energy efficiency programs are lost opportunities and incomplete actions. These problems can be caused by technology-related issues, but often the causes are institutional barriers (organizational or procedural {open_quotes}people problems{close_quotes}). Energy efficient decisions are not being made because of a lack of awareness or policy mandate, or because financial resources are not available to decisionmakers. The Bureau of Energy Conservation (BEC) is working to solve such problems in the City & County of San Francisco through the Intervention Strategies project. In the first phase of the project, using the framework of the building lifetime, we learned how energy efficiency in San Francisco municipal buildings can be influenced through delivering services to support decisionmakers; at key points in the process of funding, designing, constructing and maintaining them. The second phase of the project involved choosing and implementing five pilot projects. Through staff interviews, we learned how decisions that impact energy use are made at various levels. We compiled information about city staff and their needs, and resources available to meet those needs. We then designed actions to deliver appropriate services to staff at these key access points. BEC implemented five pilot projects corresponding to various stages in the building`s lifetime. These were: Bond Guidelines, Energy Efficient Design Practices, Commissioning, Motor Efficiency, and Facilities Condition Monitoring Program.

    Full Text Available Current energy policy of Turkey is to increase the renewable energy share in total energy and to maximize benefit from existing potential until next 15 years. It was planed that the share of renewable energy resources in electricity production would be at least 30% by 2023 and government ensured some incentives such as feed-in tariff, investment incentives etc. for renewable energy. Moreover Turkish Energy Regulatory Agency (EMRA announced that biofuel blending would be mandatory starting from 2013 and 2014 for bioethanol (2% and biodiesel (1%, respectively. This study examines the current situation and potential of renewable resources and evaluates the impacts of renewable energy policy both on the energy sector and whole national economy. Renewable energy targets can generate around 275-545 thousand direct jobs possibilities in energy sector and 7.9 thousand tones natural gas and 464 thousand cubic meters fossil fuel saving by 2023. Net trade impact of renewable energy targets will be aggravated due to mandatory biodiesel blending since Turkey has oilseed deficit. In Turkey, utilization of all type of resources will contribute to economy but most feasible and sustainable renewable energy is biomass. Between the other renewables, biomass would provide highest social well-being in the country.

    Although the population-level success of tobacco denormalization is widely accepted, it remains unclear whether these strategies alleviate health inequities for sexual and gender minorities. The high risk of smoking among sexual and gender minorities together with research that documents a relationship between stigma-related processes and smoking prevalence for these groups raises questions about whether tobacco-related stigma intensifies the disadvantages associated with the stigmas of other social identities. We have not adequately considered how tobacco-related stigma overlaps with other social identity stigmas. Given concerns about the intensification of inequality, this type of inquiry has important implications for understanding both the effectiveness and limitations of tobacco denormalization strategies for sexual and gender minorities and identifying those tobacco prevention, treatment, and public health policies that work to ameliorate health inequities.

  14. Improved Control Strategy for Microgrid Ultracapacitor Energy Storage Systems

    Directory of Open Access Journals (Sweden)

    2014-12-01

    Full Text Available Ultracapacitors (UCs, with their features of high power density and high current charge-discharge, have become the best choice for dynamic power compensation to improve the stability of microgrids and are increasingly being applied in microgrids. This paper presents the control of an energy storage system (ESS based on ultracapacitors in the context of grid-connected microgrids. The ESS is composed of DC/AC and DC/DC converters tied by a dc link. An improved dynamic model for the ESS is proposed. Based on the proposed model a Proportional-Integral-Resonant (PIR DC link voltage controller is proposed to maintain the DC link voltage through the charging-discharging control of ultracapacitors, capable of working properly under all operating conditions. An extra double frequency component is injected into the UC current by a R controller to dynamically compensate for DC instantaneous power and double frequency AC instantaneous power due to unbalanced grid conditions and disturbances. This feature maintains the DC link voltage constant under unbalanced conditions and increases the degrees of freedom of the DC/AC converter and thus facilitates the application of UCs in microgrids. Simulation and experimental results verify the effectiveness of the proposed control strategy.

    Highlights: • A market framework is presented for a proactive DISCO (PDISCO). • Two-stage wholesale markets and stochastic distributed energy resources are involved. • A one-leader multi-follower bilevel model is proposed. • Continuous strategic offers and bids are achieved. - Abstract: This paper proposes a methodology to address the trading strategies of a proactive distribution company (PDISCO) engaged in the transmission-level (TL) markets. A one-leader multi-follower bilevel model is presented to formulate the gaming framework between the PDISCO and markets. The lower-level (LL) problems include the TL day-ahead market and scenario-based real-time markets, respectively with the objectives of maximizing social welfare and minimizing operation cost. The upper-level (UL) problem is to maximize the PDISCO’s profit across these markets. The PDISCO’s strategic offers/bids interactively influence the outcomes of each market. Since the LL problems are linear and convex, while the UL problem is non-linear and non-convex, an equivalent primal–dual approach is used to reformulate this bilevel model to a solvable mathematical program with equilibrium constraints (MPEC). The effectiveness of the proposed model is verified by case studies.

    1976-12-01

    This report presents strategies for commercializing customer thermal storage. Four storage techniques are evaluated: space heating, air conditioning, hot-water heating, and interruptible hot-water heating. The storage systems involved store off-peak electric energy for thermal applications during peak load hours. Analyses of both storage techniques and principal parties affected by storage indicate four barriers: the absence of (1) commercially available air conditioning storage devices, (2) appropriate rates, (3) information on both rates and devices, and (4) widespread utility support. Development of appropriate rates is the key to commercialization. The criteria used to evaluate rate types are: maximum combined utility and customer benefits, ease of commercialization, and practical feasibility. Four rate types--demand charges, time-of-use rates, and two forms of load management rates (a monthly credit and an off-peak discount)--plus the possibility of utility ownership are considered. The best rate types for each storage option are: for hot-water heating, a monthly credit for allowing utility interruptions or an off-peak price discount for storage; for space heating, an off-peak discount contingent upon meeting utility requirements; and for air conditioning, an off-peak discount plus monthly credit.

    The framework convention on climate change, signed by more than 150 governments worldwide in June 1992, calls on parties to the convention undertaken inventories of national sources and sinks of greenhouse gases and to develop plans for responding to climate change. The energy sector is comprised of the major energy demand sectors (industry, residential and commercial, transport and agriculture), and the energy supply sector, which consists of resource extraction, conversion, and delivery of energy products. Greenhouse Gas (GHG) emissions occur at various points in the sector, from resource extraction to end use application, and accordingly, options for mitigation exist at various points. In most countries, will be a major focus of GHG mitigation analysis. The primary focus of this paper is on the identification of strategies that can mitigate climate changes on the basis of integrated energy planing analysis. The overall approach follows a methodology developed by the U.S. Country Studies Program under the framework of the Convention's commitments. It involves the development of scenarios based on energy uses and evaluation of specific technologies that can satisfy demands for energy services. One can compare technologies based on their relative cost to achieve a unit of GHG reduction and other features of interest. This approach gives equal weight to both energy supply and energy demand options. A variety of screening criteria including indicators of cost-effectiveness as well as non-economic analysis concerns, can be used to identify and assess promising options, which can then be combined to create one or more scenarios. Mitigation scenarios are evaluated against the backdrop of a baseline scenario, which simulates assumed to take place in the absence of mitigation efforts. Mitigation scenarios can be designed to meet specific emission reduction targets or to simulate the effect of specific policy inventions. The paper ends with an application using a

    Reducing greenhouse gas emissions to limit damage to the global economy climate-change-induced and secure the livelihoods of future generations requires ambitious mitigation strategies. The introduction of a global carbon tax on fossil fuels is tested here as a mitigation strategy to reduce atmospheric CO2 concentrations and radiative forcing. Taxation of fossil fuels potentially leads to changed composition of energy sources, including a larger relative contribution from bioenergy. Further, the introduction of a mitigation strategy reduces climate-change-induced damage to the global economy, and thus can indirectly affect consumption patterns and investments in agricultural technologies and yield enhancement. Here we assess the implications of changes in bioenergy demand as well as the indirectly caused changes in consumption and crop yields for global and national cropland area and terrestrial biosphere carbon balance. We apply a novel integrated assessment modelling framework, combining three previously published models (a climate-economy model, a socio-economic land use model and an ecosystem model). We develop reference and mitigation scenarios based on the narratives and key elements of the shared socio-economic pathways (SSPs). Taking emissions from the land use sector into account, we find that the introduction of a global carbon tax on the fossil fuel sector is an effective mitigation strategy only for scenarios with low population development and strong sustainability criteria (SSP1 Taking the green road). For scenarios with high population growth, low technological development and bioenergy production the high demand for cropland causes the terrestrial biosphere to switch from being a carbon sink to a source by the end of the 21st century.

    The popularity of energy drinks has increased rapidly in the past decade. One of the main reasons people use energy drinks is to counteract effects of insufficient sleep or sleepiness. Risks associated with energy drink use, including those related to sleep loss, may be disproportionately borne by racial minorities and those of lower socioeconomic status. In this review, a brief introduction to the issue of health disparities is provided, population-level disparities and inequalities in sleep are described, and the social-ecological model of sleep and health is presented. Social and demographic patterns of energy drink use are then presented, followed by discussion of the potential ways in which energy drink use may contribute to health disparities, including the following: 1) effects of excessive caffeine in energy drinks, 2) effects of energy drinks as sugar-sweetened beverages, 3) association between energy drinks and risk-taking behaviors when mixed with alcohol, 4) association between energy drink use and short sleep duration, and 5) role of energy drinks in cardiometabolic disease. The review concludes with a research agenda of critical unanswered questions. PMID:25293540

    The Danish Government's ''Energy strategy 2050'' describes how the country can achieve its independence from coal, oil and gas by the year 2050 and significantly reduce its greenhouse gas emissions. The strategy contains a raft of initiatives that will reduce the energy industry's use of fossil fuels by 33 % in 2020, compared with 2009. The reduction will put Denmark well on its way to complete independence of fossil fuels by 2050. The strategy calls for a significant increase in renewable energy obtained from wind, biomass and biogas which over the next decade will increase the share of renewable to 33 % of energy consumption, if the initiatives in the strategy are implemented. The strategy offers an economically responsible path to the conversion of the Danish energy supply, and includes specific initiatives, that are all fully financed and which will not damage the nation's competitiveness. Homeowners will experience moderate increases in the costs of heat and electricity, but will also be given opportunities to lower their energy expenses through greater efficiency. Companies can expect added expenses amounting to 0.1 % of the rise in their gross revenue growth by 2020. (ln)

  9. The implications of an increasingly decentralised energy system

    Wolfe, Philip

    2008-01-01

    The UK government has signalled that the increasing use of decentralised energy forms part of its plan to achieve the UK's contribution to the EU's sustainable energy targets. Much of the technology for decentralised energy already exists, although it is not widely used in the UK. There will be need for new developments in onsite energy production, and in the delivery, integration and regulatory infrastructure to support it. Other State of Science reviews for this project describe particular energy technologies, but this paper highlights selected developments in thermal technologies and in biological processes which offer the potential for breakthroughs in converting biomass to energy. The effectiveness and deployment of decentralised energy can be enhanced by systems and infrastructure technology, not just for electricity but also in heat and biogas networks. Such systems are expected to be a focus of rapid development over the next two decades. Opportunities exist particularly in active networks, smart metering and intelligent tariff-interactive load management. Substantial regulatory and policy reform will be required to optimise the potential for onsite energy generation and effective two-way interchanges with centralised energy systems. There will be need for a regulatory system for heat networks and appropriate incentives for active networks. The development of an energy services business model in the industry will not progress until the compensation model changes to make it viable. The strength of the drivers for a trend towards decentralised energy, coupled with a wide range of scientific developments, should make this a very dynamic sector and present a host of new opportunities for British technology

  11. An optimal staggered harvesting strategy for herbaceous biomass energy crops

    Biofuel research over the past two decades indicates lignocellulosic crops are a reliable source of feedstock for alternative energy. However, under the current technology of producing, harvesting and converting biomass crops, the cost of biofuel is not competitive with conventional biofuel. Cost of harvesting biomass feedstock is a single largest component of feedstock cost so there is a cost advantage in designing a biomass harvesting system. Traditional farmer-initiated harvesting operation causes over investment. This study develops a least-cost, time-distributed (staggered) harvesting system for example switch grass, that calls for an effective coordination between farmers, processing plant and a single third-party custom harvester. A linear programming model explicitly accounts for the trade-off between yield loss and benefit of reduced machinery overhead cost, associated with the staggered harvesting system. Total cost of producing and harvesting switch grass will decline by 17.94 percent from conventional non-staggered to proposed staggered harvesting strategy. Harvesting machinery cost alone experiences a significant reduction of 39.68 percent from moving from former to latter. The net return to farmers is estimated to increase by 160.40 percent. Per tonne and per hectare costs of feedstock production will decline by 17.94 percent and 24.78 percent, respectively. These results clearly lend support to the view that the traditional system of single period harvesting calls for over investment on agricultural machinery which escalates the feedstock cost. This social loss to the society in the form of escalated harvesting cost can be avoided if there is a proper coordination among farmers, processing plant and custom harvesters as to when and how biomass crop needs to be planted and harvested. Such an institutional arrangement benefits producers, processing plant and, in turn, end users of biofuels.

The simulations employ a code suite that generates and fits realistic light curves in order to obtain distance modulus/redshift pairs that are passed to a cosmology fitter. We investigated several different survey strategies including field selection, supernova selection biases, and photometric redshift measurements. Using the results of this study, we chose a 30 deg 2 search area in the griz filter set. We forecast (1) that this survey will provide a homogeneous sample of up to 4000 Type Ia supernovae in the redshift range 0.05 < z < 1.2 and (2) that the increased red efficiency of the DES camera will significantly improve high-redshift color measurements. The redshift of each supernova with an identified host galaxy will be obtained from spectroscopic observations of the host. A supernova spectrum will be obtained for a subset of the sample, which will be utilized for control studies. In addition, we have investigated the use of combined photometric redshifts taking into account data from both the host and supernova. We have investigated and estimated the likely contamination from core-collapse supernovae based on photometric identification, and have found that a Type Ia supernova sample purity of up to 98% is obtainable given specific assumptions. Furthermore, we present systematic uncertainties due to sample purity, photometric calibration, dust extinction priors, filter-centroid shifts, and inter-calibration. We conclude by estimating the uncertainty on the cosmological parameters that will be measured from the DES supernova data.

The discussion focuses on the basic differences between the two hypotheses and their implications, with regard to the reconstruction methodology, ribosome emergence, balance between ribozymes and protein enzymes, and their major difficultites. Additional complexities of the two hypotheses, such as membranes and the energy source of the first reactions, are not treated in the present work. A central element in the proposed experimental strategies is the study of the catalytic activites of very small peptides and RNA-like oligomers, according to existing, as well as to yet-to-be-invented scenarios of the two hypothesis under consideration. It is suggested that the novel directed molecular evolution technology, and molecular computational modeling, can be applied to this research. This strategy is assumed to be essential for the suggested goal of future studies of the origin of life, namely, the establishment of a `Primordial Darwinian entity'.

    This Series has examined the health implications of policies aimed at tackling climate change. Assessments of mitigation strategies in four domains-household energy, transport, food and agriculture, and electricity generation-suggest an important message: that actions to reduce greenhouse-gas emissions often, although not always, entail net benefits for health. In some cases, the potential benefits seem to be substantial. This evidence provides an additional and immediate rationale for reductions in greenhouse-gas emissions beyond that of climate change mitigation alone. Climate change is an increasing and evolving threat to the health of populations worldwide. At the same time, major public health burdens remain in many regions. Climate change therefore adds further urgency to the task of addressing international health priorities, such as the UN Millennium Development Goals. Recognition that mitigation strategies can have substantial benefits for both health and climate protection offers the possibility of policy choices that are potentially both more cost effective and socially attractive than are those that address these priorities independently.

  20. Potentials and policy implications of energy and material efficiency improvement

    Energy Technology Data Exchange (ETDEWEB)

    1997-01-01

    There is a growing awareness of the serious problems associated with the provision of sufficient energy to meet human needs and to fuel economic growth world-wide. This has pointed to the need for energy and material efficiency, which would reduce air, water and thermal pollution, as well as waste production. Increasing energy and material efficiency also have the benefits of increased employment, improved balance of imports and exports, increased security of energy supply, and adopting environmentally advantageous energy supply. A large potential exists for energy savings through energy and material efficiency improvements. Technologies are not now, nor will they be, in the foreseeable future, the limiting factors with regard to continuing energy efficiency improvements. There are serious barriers to energy efficiency improvement, including unwillingness to invest, lack of available and accessible information, economic disincentives and organizational barriers. A wide range of policy instruments, as well as innovative approaches have been tried in some countries in order to achieve the desired energy efficiency approaches. These include: regulation and guidelines; economic instruments and incentives; voluntary agreements and actions, information, education and training; and research, development and demonstration. An area that requires particular attention is that of improved international co-operation to develop policy instruments and technologies to meet the needs of developing countries. Material efficiency has not received the attention that it deserves. Consequently, there is a dearth of data on the qualities and quantities for final consumption, thus, making it difficult to formulate policies. Available data, however, suggest that there is a large potential for improved use of many materials in industrialized countries.

    Energy plays an important role in the development of the Sahel Countries. For instance, in these countries, the use of wood fire is essential as a source of energy. However, the increase in the wood supply leads to environmental problems; hence the necessity for the states to promote alternative source of energy to replace the wood. Used in the field of agriculture, transport, industry and construction, energy in Sahel countries hurts to financial problems such as difficulties in the funding of oil import and supply security. It is then indispensable to develop energy resources in the Sahel countries. Energy policies must emphasize on hydroelectric energy, nuclear energy and also better reorganize certain sources of energy such as gas, oil, and coal. Thus this political assumption of responsibility through a comprehensive approach will contribute to generate the development of the Sahel countries [fr

    Burkina Faso does not have fossil energy source. The problem of energy thus arises with acuity for the rural and urban populations. The energy sources used are primarily the hydrocarbons, electrical energy, the woody fuels as new and renewable energies which are the biomass, the solar energy and the wind energy. The hydrocarbons are 100% imported, which makes the country very depend on over sea with respect to its conventional energy supply. These imports represent, for the years 1987 to 1992, 12 to 29% of the export earnings of the country. In addition to this dependence, there is a great weakness of the electrical communication and the too high cost of energy which led to the development of a strategic planning of the scientific research centered on the energy sector. In this field, research made it possible to undertake a study of the Burkina Faso energy system, to evaluate and exploit solar energy and wind mill, to develop the use of new methods allowing the energy saving in the households and the safeguard of the environment. In addition research shows that an economy is possible in the administrative buildings. Work is undertaken on air-conditioning by evaporation, the technology of the cold and the valorization of nonfood plant oils. There is also a work done on the de-pollution of industrial waste water, the energy valorization of the biomass as well as the improvement of the technology of the dolo, local beer containing sorghum. All these scientific research activities aim at the definition of a development policy on the energetic sector which takes into account the reduction of the cost of energy, the access of the populations to this resource, the reduction in the invoice of oil products imports as well as the promotion of environmental protection, the industrial development and that of the new methods of local technology as regards energy in Burkina Faso [fr

    In nongravitational physics the local density of energy is often regarded as merely a bookkeeping device; only total energy has an experimental meaning—and it is only modulo a constant term. But in general relativity the local stress-energy tensor is the source term in Einstein's equation. In closed universes, and those with Kaluza-Klein dimensions, theoretical consistency demands that quantum vacuum energy should exist and have gravitational effects, although there are no boundary materials giving rise to that energy by van der Waals interactions. In the lab there are boundaries, and in general the energy density has a nonintegrable singularity as a boundary is approached (for idealized boundary conditions). As pointed out long ago by Candelas and Deutsch, in this situation there is doubt about the viability of the semiclassical Einstein equation. Our goal is to show that the divergences in the linearized Einstein equation can be renormalized to yield a plausible approximation to the finite theory that presumably exists for realistic boundary conditions. For a scalar field with Dirichlet or Neumann boundary conditions inside a rectangular parallelepiped, we have calculated by the method of images all components of the stress tensor, for all values of the conformal coupling parameter and an exponential ultraviolet cutoff parameter. The qualitative features of contributions from various classes of closed classical paths are noted. Then the Estrada-Kanwal distributional theory of asymptotics, particularly the moment expansion, is used to show that the linearized Einstein equation with the stress-energy near a plane boundary as source converges to a consistent theory when the cutoff is removed. This paper reports work in progress on a project combining researchers in Texas, Louisiana and Oklahoma. It is supported by NSF Grants PHY-0554849 and PHY-0554926.

    Highlights: • An energy-saving control strategy is proposed for multi-group lighting sources. • The proposed controller is designed to minimize the light-energy consumption. • It is designed to speed up the convergence rate without increasing the oscillation. • The minimal energy usage is guaranteed, while keeping the desired lighting level. • Experimental results shows the superiorities of the energy-saving control strategy. - Abstract: In recent years, the energy problem has been a universal concern. In order to improve the lighting energy efficiency and reduce the electric energy consumption, this paper develops an energy-saving control strategy for the lighting system with multiple lighting sources. The control strategy presented in this paper includes two parts: a new multivariate extremum seeking control method with Newton algorithm is developed to minimize the light-energy consumption by separately manipulating the brightness of multiple lighting sources, and a proportion-integration-differentiation control approach is adopted to realize the desired lighting level. The proposed scheme can increase the convergence speed of the closed loop system toward the minimum light-energy consumption, meanwhile, the accuracy of the control strategy will be improved. Experimental results illustrate that the light-energy consumption via the proposed method can reach more rapidly to a smaller vicinity of the minimum energy point, so, the lighting energy efficiency is greatly increased accordingly.

    The Danish Government's long-term energy strategy follows up on the political agreement of 29 March 2004. The energy strategy is a coherent formulation of the Government's long-term energy policy. The pivotal point for the energy strategy is liberalized energy markets and market based tools for obtaining goals such as efficiency, security of supply and environment. The focus is increasingly on the substantial business potential within development of new and more efficient energy technology, in which Denmark takes up several globally strong positions. Furthermore, transportation energy consumption has been included directly in an energy strategy for the first time. At the same time as the energy strategy is presented, a summarizing background report from the Danish Energy Agency with facts, analyses and evaluations is published, as well as a report from energinet.dk that summarizes the system responsibilities' input to that part of the energy strategy that deals with power infrastructure.

  17. Saturation wind power potential and its implications for wind energy.

    Jacobson, Mark Z; Archer, Cristina L

    2012-09-25

    Wind turbines convert kinetic to electrical energy, which returns to the atmosphere as heat to regenerate some potential and kinetic energy. As the number of wind turbines increases over large geographic regions, power extraction first increases linearly, but then converges to a saturation potential not identified previously from physical principles or turbine properties. These saturation potentials are >250 terawatts (TW) at 100 m globally, approximately 80 TW at 100 m over land plus coastal ocean outside Antarctica, and approximately 380 TW at 10 km in the jet streams. Thus, there is no fundamental barrier to obtaining half (approximately 5.75 TW) or several times the world's all-purpose power from wind in a 2030 clean-energy economy.

    The United Nations Framework Convention on Climate Change calls for ''stabilization of greenhouse-gas concentrations in the atmosphere at a level that would prevent dangerous anthropogenic interference with the climate system...''. A standard baseline scenario that assumes no policy intervention to limit greenhouse-gas emissions has 10 TW (10 x 10 12 watts) of carbon-emission-free power being produced by the year 2050, equivalent to the power provided by all today's energy sources combined. Here we employ a carbon-cycle/energy model to estimate the carbon-emission-free power needed for various atmospheric CO 2 stabilization scenarios. We find that CO 2 stabilization with continued economic growth will require innovative, cost-effective and carbon-emission-free technologies that can provide additional tens of terawatts of primary power in the coming decades, and certainly by the middle of the twenty-first century, even with sustained improvement in the economic productivity of primary energy.

  19. ENVIRONMENTAL IMPLICATIONS OF THE INCREASING DEMAND FOR ENERGY

    Directory of Open Access Journals (Sweden)

    2012-07-01

    Full Text Available During human society’s development on large geographical areas, a series of cultural systems have appeared and have determined a certain approach concerning the environment and social relations. These systems of thought persist even today and they are strongly influenced by individuals’ thinking and approaches in that society, thing that requires a specific approach for the implementation of these relatively new concepts (e.g. sustainable development, pollution, ecological approaches on social life. Furthermore, the continuous growth of the demand for energy in the world is seen as an alarm. Between 1970 and 1997 world energy consumption has almost doubled and it is projected to grow by about 57% during 2004-2030 and the thing which should be mentioned is that with the increasing energy demand, pollution levels will increase too. But we must not forget that electric and thermal power represent one of the basic needs of mankind, and when the fulfilment of this need started to affect the climate and implicitly human health this problem turned into a hardly manageable one. We must not forget that the world’s population is growing rapidly and the level of pollution per capita increased we might even say in direct proportion. In many cases, increased pollution has its explanation in the growing number of individuals at global level and also the increasing needs, desires, aspirations, standard of living, of these. This paper intends to objectively analyse the interconnections that arise between the environment and the growth of the demand for energy, emphasizing the devastating effects of pollution created by burning fossil fuels in order to obtain electric and thermal power as well as the current and future possibilities for the replacement of these energy reserves with renewable energy reserves. The whole analysis will be accompanied by case studies and will follow strictly imposed goals by sustainable development.

    2011-01-01

    This paper discusses Point Lepreau Generating Station's waste management experiences during the Refurbishment outage. In short, Point Lepreau GS has been challenged during the outage due to the amount of low and intermediate level waste that has been generated compared to that which was expected, which has driven the need to develop a new waste management strategy in the middle of the outage. The paper presents an overview of pre-outage waste handling, what process changes and schedule changes occurred during the outage, and provides a discussion of the operational and financial consequences of those changes. Key issues highlighted by the paper include the need for adequate provision of waste management facilities during large outages, the importance of ensuring that contractors have a stake in waste minimization activities, and long term waste management implications that need to be considered for large outages.

    Berry, Trimble, and Olmedo's (1986) acculturation model was used to investigate the relationship among adolescents' acculturation strategies, personal self-esteem, and collective self-esteem. Using data from 427 high school students, factor analysis results distinguished Collective Self-esteem Scale constructs (Luhtanen & Crocker, 1992) from both ethnic identity and outgroup orientation subscales of the Multigroup Ethnic Identity Measure (Phinney, 1992). Subsequent results showed that: 1) both acculturation dimensions were correlated with personal and collective self-esteems, 2) integrationists shared similar levels of personal and collective self-esteems with assimilationists and/or separationists, and 3) marginalizationists generally had the lowest levels of personal and collective self-esteems. Implications are drawn for understanding acculturation among adolescents and for the utility of group-level measures of self-esteem. (c) 2006 APA, all rights reserved.

    In order to improve the efficiency of energy conversion and increase the driving range of electric vehicles, the regenerative energy captured during braking process is stored in the energy storage devices and then will be re-used. Due to the high power density of supercapacitors, they are employed to withstand high current in the short time and essentially capture more regenerative energy. The measuring methods for regenerative energy should be investigated to estimate the energy conversion efficiency and performance of electric vehicles. Based on the analysis of the regenerative braking energy system of a supercapacitor vehicle, an evaluation system for energy recovery in the braking process is established using USB portable data-acquisition devices. Experiments under various braking conditions are carried out. The results verify the higher efficiency of energy regeneration system using supercapacitors and the effectiveness of the proposed measurement method. It is also demonstrated that the maximum regenerative energy conversion efficiency can reach to 88%. Copyright © 2014 ISA. Published by Elsevier Ltd. All rights reserved.

    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

    The two major aims of our lab are as follows: First, to develop and field-test general mechanistic models that predict animal life history characteristics as influenced by climate and the physical, physiological behavioral characteristics of species. This involves: understanding how animal time and energy budgets are affected by climate and animal properties; predicting growth and reproductive potential from time and energy budgets; predicting mortality based on climate and time and energy budgets; and linking these individual based models to population dynamics. Second to conduct empirical studies of animal physiological ecology, particularly the effects of temperature on time and energy budgets. The physiological ecology of individual animals is the key link between the physical environment and population-level phenomena. We address the macroclimate to microclimate linkage on a broad spatial scale; address the links between individuals and population dynamics for lizard species; test the endotherm energetics and behavior model using beaver; address the spatial variation in climate and its effects on individual energetics, growth and reproduction; and address patchiness in the environment and constraints they may impose on individual energetics, growth and reproduction. These projects are described individually in the following section. 24 refs., 9 figs.

    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.

    Shortly after the Fukushima accident, the German chancellor, Angela Merkel, announced a new course for the country's energy policy: nuclear power is to be fully abandoned by 2022, owing to a massive recourse to renewable sources of energy. The proclaimed goal is for renewable energy to make up 35% of the country's energy mix by 2035 and even 80% by 2050. This energy transition, though benefiting from a consensus, has run up against several difficulties: an unadapted electric power grid, the excessively high costs of investment, and exorbitant electricity rates for consumers.... Till now, this energy policy's basis principles have not come under question, but questioning are arising about the pace and cost of this transformation. (author)

    The Regional Issues Identification and Assessment (RIIA) program is an evaluation of the regional impacts of future energy development. These studies are conducted for the Department of Energy. The impacts described in this paper for 1990 are based on a national energy projection (scenario) that assumes medium energy demand and fuel supply through 1990, but does not incorporate the policies of the 1978 National Energy Act. The RIIA study plan uses the predicted fuel mixes derived from the PIES scenario as a starting point for its analysis. County level patterns for utility, industry and mining activities for 1990 were then developed from the federal region totals. Energy sources addressed were coal, nuclear, oil, oil shale, gas, geothermal, hydroelectric, and solar. The impact of these county-level patterns of utility, industry, and mining activities on the air, water, and land resources of the country and on the socioeconomic and health and safety aspects of the nation's welfare are analyzed

    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.

The best (and only consistent) attitudinal predictor of residents' actual energy consumption was their attitude about thermal comfort. A number of other attitudes that could conceivably have been related to consumption, such as attitudes about the reality of the crisis, were not found to be related to consumption. Another major focus of the project was on the effectiveness of feedback (that is, giving residents information about their energy use) as an aid to residents' conservation efforts. A series of experiments demonstrated that frequent, credible energy-consumption feedback, coupled with encouragement to adopt a reasonable but difficult energy-conservation goal, could facilitate conservation. However, these studies also demonstrated that residents could not be given just any kind of information about their energy use as feedback and that even proper feedback would not lead to conservation in all households. Conditions that are crucial for the success of feedback as a conservation aid are discussed. Other studies conducted by the project looked at the effect on energy consumption of (1) a device to reduce air-conditioning waste by signalling when it is cool outside, (2) an automatic multi-setback thermostat, and (3) utility companies' average payment plans. A survey of residents' knowledge of their energy use also was conducted. 23 references.

    This book published by the Energy Science Center (ESC) at the Swiss Federal Institute of Technology (ETH) in Zurich presents a wide selection of reports on how the challenge of dealing with climate change can be met. The 69 reports included cover a wide range of topics ranging from traffic modelling, biofuels and electrification of power trains, through demand-side management, electricity production and distribution and life cycle assessment, to the integration of wind power and renewable energy technologies. Also, climate policy matters are dealt with as are nano-technology applications in the energy area and the integration of energy conversion and production processes and waste management.

  3. Exploring past energy changes and their implications for the pace of penetration of new energy technologies

    Possible growth paths for new electricity generation technologies are investigated on the basis of an empirical analysis of past penetration rates. Finding and understanding high market penetration scenarios is relevant to formulating climate change mitigation strategies. The analysis shows that under favorable growth conditions, photovoltaics and wind could produce 15% and 25%, respectively, of world electricity by 2050. Under the same assumptions nuclear power could increase to 41% of world electricity. But it is unlikely that all three technology paths could be realized up to these values simultaneously and therefore the penetration rates presented here should be considered as indicative only. The results show that under positive conditions, an embryonic technology could move as a preferred option into a mainstream energy source within half a century. The introduction of growth constraints reflecting, e.g., severe economic, technical, or political limitations could reduce the above numbers by a factor of up to 2-3. The results indicate a decline in the relative year-to-year growth of new technologies when they have higher market shares. A comparison of the results with other short-term and long-term technology scenarios shows satisfactory agreement.

    Energy typically represents the single largest controllable cost in manufacturing, and is under constant scrutiny by all levels of management. In this paper we will examine the role and components of an energy management strategy, and focus on the benefits of looking at the strategy from a business perspective. We will then examine the role that an effective program, either existing or new, can play in a collaborative manufacturing environment, and how these improvements can reduce energy requirements while maintaining, or improving productivity.

    The principal conclusions that can be made based on the estimated costs reported in this paper are twofold. First, hybrid reactors operating symbiotically with conventional fission reactors are a potentially attractive supply alternative. Estimated hybrid energy system costs are slightly greater than estimated costs of the most attractive alternatives. However, given the technological, economic, and institutional uncertainties associated with future energy supply, differences of such magnitude are of little significance. Second, to be economically viable, hybrid reactors must be both fuel producers and electricity producers. A data point representing each hybrid reactor driver-blanket concept is plotted as a function of net electrical production efficiency and annual fuel production. The plots illustrate that the most economically viable reactor concepts are those that produce both fuel and electricity

    Full Text Available PPARs are ligand activated transcription factors. PPARγ agonists have been reported as a new and potentially efficacious treatment of inflammation, diabetes, obesity, cancer, AD, and schizophrenia. Since cancer cells show dysregulation of glycolysis they are potentially manageable through changes in metabolic environment. Interestingly, several of the genes involved in maintaining the metabolic environment and the central energy generation pathway are regulated or predicted to be regulated by PPARγ. The use of synthetic PPARγ ligands as drugs and their recent withdrawal/restricted usage highlight the lack of understanding of the molecular basis of these drugs, their off-target effects, and their network. These data further underscores the complexity of nuclear receptor signalling mechanisms. This paper will discuss the function and role of PPARγ in energy metabolism and cancer biology in general and its emergence as a promising therapeutic target in breast cancer.

    Analysis of carbon emissions paths stabilizing atmospheric CO{sub 2} in the 350--750 ppmv range reveals that implementing the UN Climate Convention will become increasingly difficult as the stabilization target decreases because of increasing dependence on carbon-free energy sources. Even the central Intergovernmental Panel on Climate Change scenario (IS92a) requires carbon-free primary power by 2050 equal to the humankind`s present fossil-fuel-based primary power consumption {approximately}10 TW (1 TW = 10{sup 12} W). The authors describe and critique the assumptions on which this projection is based, and extend the analysis to scenarios in which atmospheric CO{sub 2} stabilizes. For continued economic growth with CO{sub 2} stabilization, new, cost-effective, carbon-free technologies that can provide primary power of order 10 TW will be needed in the coming decades, and certainly by mid-century, in addition to improved economic productivity of primary energy.

    Occupant concern about indoor air quality (IAQ) issues has led to the increased use of more effective air filters in residential heating and cooling systems. This study performed measurements in ten California houses to determine the effects of changing filter performance and related characteristics on the energy use of the heating and cooling systems. Multiple filters were evaluated covering a wide range of filter effectiveness from simple low filtration fiberglass filters up to high efficiency filters that might be used by occupants concerned about IAQ. Sophisticated analysis and simulation tools used the field-testing results to determine filter impacts for a wide range of parameters and California climates. The results indicate that for MERV 10/11/13 filters the effects on energy use are moderate (<5%) over a wide range of performance conditions and climates. Using higher MERV 16 filters can lead to significantly increased energy use (>5%). The high airflow resistance of MERV 16 filters led to excess noise in some test houses from air bypassing the filter and the blower motor. Filter loading rates varied more from house to house than by MERV rating and overall were quite low in many of the homes. Filter related energy use does not need to be addressed for filters of MERV 10/11/13 and MERV 16 filters should only be used with low leakage tested ducts unless the filter is mounted at the blower compartment. MERV 16 filters should only be used if the filter area is sufficient to prevent noise issues and if the duct system has low air flow resistance and low leakage. Filters should be labeled for their air flow resistance, or static pressure at a particular flow rate, that would allow codes and standards to reference a particular performance specification and allow contractors and homeowners to make informed purchases.

  12. Energy and air emission implications of a decentralized wastewater system

    2012-01-01

    Both centralized and decentralized wastewater systems have distinct engineering, financial and societal benefits. This paper presents a framework for analyzing the environmental effects of decentralized wastewater systems and an evaluation of the environmental impacts associated with two currently operating systems in California, one centralized and one decentralized. A comparison of energy use, greenhouse gas emissions and criteria air pollutants from the systems shows that the scale economies of the centralized plant help lower the environmental burden to less than a fifth of that of the decentralized utility for the same volume treated. The energy and emission burdens of the decentralized plant are reduced when accounting for high-yield wastewater reuse if it supplants an energy-intensive water supply like a desalination one. The centralized facility also reduces greenhouse gases by flaring methane generated during the treatment process, while methane is directly emitted from the decentralized system. The results are compelling enough to indicate that the life-cycle environmental impacts of decentralized designs should be carefully evaluated as part of the design process. (letter)

  13. An Improved Energy Management Strategy for Hybrid Energy Storage System in Light Rail Vehicles

    Directory of Open Access Journals (Sweden)

    Long Cheng

    2018-02-01

    Full Text Available A single-objective optimization energy management strategy (EMS for an onboard hybrid energy storage system (HESS for light rail (LR vehicles is proposed. The HESS uses batteries and supercapacitors (SCs. The main objective of the proposed optimization is to reduce the battery and SC losses while maintaining the SC state of charge (SOC within specific limits based on the distance between consecutive LR stations. To do this, a series of optimized SOC limits is used to prevent the SC from becoming exhausted prematurely instead of the standard SC SOC penalty term in the cost function. Meanwhile, a rule-based EMS (RB-EMS is used to give the SCs charging priority over the batteries when the vehicle is braking. Moreover, a simplified method for the optimization is proposed to reduce the computational burden. Simulation and experimental results for the proposed EMS and a standard SC SOC penalty-based cost function optimization are provided to evaluate losses. As a result, it is shown that the proposed EMS, compared with standard SC SOC penalty-based cost function optimization, decreases losses and prevents the SOC from reach the discharging limits.

    Women in rural areas are particularly affected by poor access to reliable energy sources such as electricity, thus forcing households to turn to biofuels such as wood and dung to cook, light, and warm their homes. This “energy poverty” remains one of the most formidable challenges to any progress in global development.

  18. Influence of smallholder farmers’ perceptions on adaptation strategies to climate change and policy implications in Zimbabwe

    Full Text Available Smallholder agricultural production is largely affected by climate change and variability. Despite the negative effects brought by climate variability, smallholder farmers are still able to derive livelihoods. An understanding of factors that influence farmers’ responses and adaptation to climate variability can improve decision making for governments and development partners. This study investigated farmers’ perceptions and adaptation strategies to climate change and how these influence adaptation policies at local level. A survey was conducted with 100 households randomly selected from Chiredzi district. Data collected was used to derive farmer perceptions to climate change as well as the influence of their perceptions and subsequent adaptation methods to ensuing local agricultural adaptation measures and policies. The results indicated that smallholder farmers perceived general reduction in long-term annual rainfall and rising local average temperatures. Adverse trends in rainfall and average temperature perceived by farmers were consistent with empirical data. These perceptions and other socio-economic factors helped to shape smallholder farmer agricultural adaptation strategies. Policy implications are that the government and development partners should seek ways to assist autonomous adaptations by farmers through investments in planned adaptation initiatives.

    A number of reactor deployment strategies for long-term nuclear system development are analyzed from a global perspective in terms of resource utilization and economic benefits. Two time frames are chosen: 1975 - 2025 and 1975 - 2050. Uranium demand for various strategies is compared with uranium supply assuming different production capabilities and resource base. The analysis shows that a given reactor deployment strategy could strongly influence the extent of uranium exploration and production. Power systems cost comparisons are made to identify clearly competitive or non-competitive reactors. The sensitivity of power cost to different uranium price projections and nuclear demands is also examined. The results indicate that breeders are necessary to support a long-term nuclear power system. Advanced converter-breeder symbiotic systems, particularly those operating on the Th/U-233 cycle, have clear advantages in terms of resources and economics

    This paper investigates energy resilience of countries by quantifying the supplier diversification of both direct and embodied energy import. In particular, we quantify two approaches to diversify a country's supplier portfolio: by lowering the dependency on each supplier (portfolio diversification) and by having embodied energy suppliers that are different from its direct energy suppliers (portfolio differentiation). We examine possibilities for strategic utilization of embodied energy trade to compensate for low diversity of direct energy trade for three types of fossil resources: coal, oil, and gas. We find that the diversity of embodied energy import is much greater than that of direct energy import. Of the three energy resources, coal enables countries to adopt portfolio diversification and portfolio differentiation more than gas and oil. Our results suggest embodied energy can be considered as a transfer of energy resources across national borders that can directly benefit from the diversity of the world energy production by “skipping” the limited diversity of the world energy export. - Highlights: • We quantify the diversity of countries’ supplier-portfolios of embodied energy. • The diversities of embodied energy import are greater than direct energy import. • Embodied energy is energy transfer that “skips” limited diversity of energy trade.

  1. Long term energy and emission implications of a global shift to electricity-based public rail transportation system

    With high reliance on light-duty vehicles in the present, the future of global transportation system is also geared towards private modes, which has significant energy and emission implications. Public transportation has been argued as an alternative strategy for meeting the rising transportation demands of the growing world, especially the poor, in a sustainable and energy efficient way. The present study analyzes an important yet under-researched question – what are the long-term energy and emission implications of an electric rail based passenger transportation system for meeting both long and short distance passenter transportation needs? We analyze a suite of electric rail share scenarios with and without climate policy. In the reference scenario, the transportation system will evolve towards dominance of fossil based light-duty vehicles. We find that an electric rail policy is more successful than an economy wide climate policy in reducing transport sector energy demand and emissions. Economy wide emissions however can only be reduced through a broader climate policy, the cost of which can be reduced by hundreds of billions of dollars across the century when implemented in combination with the transport sector focused electric rail policy. Moreover, higher share of electric rail enhances energy security for oil importing nations and reduces vehicular congestion and road infrastructure requirement as well. -- Highlights: •Economy wide carbon price policy will have little impact on transportation emissions. •Focused energy and emission mitigation policies required for transportation sector. •Large global shift towards electric rail based public transport is one possible option. •Transport sector focused policy will have marginal impact on total global emissions. •A combined transport sector and economy wide policy can reduce costs significantly

    The energy balances of most African countries suggest that biofuels (wood fuel, crop and wood dues, and dung) constitute the largest share of total energy consumption (up to 97% in some sub-Saharan African countries). There is, however an increasing scarcity of wood fuel (fuel wood and charcoal), the major biofuel, and a feared increase in greenhouse gas (GHG) emissions associated with biofuel combustion. The extent of GHG emissions is estimated from biofuel consumption levels that are in turn based on methodologies that might be inaccurate. A questionnaire, supplemented by informal interviews, are used to collect data, yielding information regarding end-uses, technologies used, scale of consumption, determinants of fuel consumption, and interfuel substitution (among other parameters). The survey revealed that cooking is the major end-use, with other common uses, such as space and water heating. Improved stoves that provide better combustion efficiency and, thus, reduce wood fuel consumption have not been widely disseminated and are associated with higher methane emissions than open fires. More than 90% of the households in Africa use open fires. Consumption is presented as per capita for households and as products and quantity of fuel in the small scale industries, commercial, and public sectors. Among the determinants for biofuel consumption are affordability, availability of the fuel, and interfuel substitutions. Flaws in estimating biofuel consumption yield large uncertainties in GHG emissions, with implications for the development of policies on energy planning and environmental protection. However, the application of scenarios can guide policy formulation. 5 tabs., 42 refs

    The future of nuclear energy is widely discussed with emphasis on the compatibility with social structure. Projected growth of nuclear power generation, demands for nuclear fuel resources and services, and comparison of power generation costs with other energy sources are presented and discussed based on the published data. As one of the processing problems in fuel cycle industry, the problem of reprocessing plant is discussed mainly from the view point of managing radioactive wastes including trans-actinides. Here the importance of establishing regulating standards is emphasized. A logical decision process for regulating large scale nuclear power development is proposed and explained and it is concluded that the largest obstacle for large scale development is the lack of decisions about regulation. In other words, the problem is not of technological feature but of software. Other problems discussed in this paper include, the multipurpose utilization of nuclear energy with the combination of LWR, FBR, and HTR, plutonium physical protection, the problem of energy park, and multi-national energy center. Finally, a historical review is given of the relations between the scale of energy utilization and the social structure and technological innovations. It is deduced that a new social pattern will be required for the large scale utilization of nuclear energy. (Aoki, K.)

    The paper analyses the past period of about the 10 years from the point of view of strategic considerations, documents drawn up and everything that has been accomplished. This was the period of intensive reforms of the energy sector in the Eu, but also in all other European countries, in particular in the candidate states. The mentioned period is marked by political and economic reforms and intensive economic growth of highly populated countries especially in Asia and dramatic changes in the established geo-balance of energy production and consumption. Among the developments that loom large on energy sector it is important to mention growing terrorism, war in Iraq and Middle East. The analyses carried out in this paper show that the set goals should not be changed because they became universal for all countries which organize their energy sectors based on the open market concept and responsible energy management. Problems are evident in implementation of strategic choices and therefore the emphasis is put on further implementation efforts. The analysis of other factors influencing the energy sector indicate the enhancing international cooperation, ranging from scientific researches to joint energy projects, and for Croatia it translates as a need for stronger integration in all processes and projects on the continent.

    During the last few years, political support for renewable energies has been growing continuously both at the national and international level and most scientists now agree that the Middle East and North Africa (MENA) are perfectly placed to play a leading role in the lucrative future solar and wind power industries. The interest for the development of renewable energies was perceived very early in Algeria with the creation of the solar energy institute as soon as 1962. Algeria plays a very important role in world energy markets, both as a significant hydrocarbons producer and exporter, as well as a key participant in the renewable energy market. Due to its geographical location, Algeria holds one of the highest solar reservoirs in the world. This paper deals with a review of the present renewable energy (RE) situation and assessed present and future potential of RE sources in Algeria. It also discusses the trends and expectation in solar and wind systems applications and the aspects of future implementation of renewable energies making emphasis on the Middle East and North Africa (MENA) region status. The problem related to the use of RES and polices to enhance the use of these sources are also analysed in this paper. In addition the available capacity building, the technical know-how for each RE sources technology and localising manufacturing of RE equipments have been defined. (author)

  8. The learning potential of photovoltaics: implications for energy policy

    Zwaan, Bob van der; Rabl, Ari

    2004-01-01

    This article examines the prospects for cost reductions of flat panel photovoltaic (PV) electricity. Current PV production cost ranges are presented, in terms of cost per peak W and cost per kWh, for single crystalline and multi-crystalline silicon, as well as for thin-film technologies. Possible decreases of these costs are assessed, as expected based on learning curves. The cumulative production needed to reach 'breakeven' (at which PV is competitive with conventional alternatives) is estimated for a range of values of the learning curve parameter. The cost of this cumulative production is calculated, and the question is posed whether and how the 'cost cap' can be bridged, the latter being the difference between what this cumulative production will cost and what it would cost if it could be produced at a currently competitive level. We also estimate how much PV could gain if external costs (due to environmental and health damage) of energy were internalised, for example by an energy tax. The conclusions are: (1) mainly due its high costs, PV electricity is unlikely to play a major role in global energy supply and carbon emissions abatement before 2020, (2) extrapolating past learning curves, one can expect its costs to decrease significantly, so that a considerable PV electricity share world-wide could materialise after 2020, (3) niche-market applications, e.g. using stand-alone systems in remote areas, are crucial for continuing 'the ride along the learning curve', (4) damage costs of conventional (fossil) power sources are considerable, and they could provide an important part of the rationale behind major policy efforts to encourage increased use of PV. The costs involved with such policies would be elevated, but a considerable share of these costs could be justified by the fact that conventional power damage costs constitute a significant fraction of the cost gap, although probably not enough to close it

    To enhance still more effectively the research and development of energy-related/environmental technologies, research and development strategies have to be worked out from a long-term view point and policy resources such as investment in research and development should be optimally distributed after clarifying and defining the course to follow toward the achievement of research and development goals. This project aims to conduct studies, and to show the course to follow in the future, towards the establishment of a long-term energy technological strategy by investigating energy systems for around 2050, interim energy systems at the intermediate stage, and innovative energy technologies for realizing such energy systems. In Chapter 1, the position of the survey and its purpose and prerequisites are shown. In Chapter 2, the history of social and economic conditions surrounding energy/environmental technologies and of energy situation up to the present time is compiled, and the outlook is analyzed and predicted. In Chapter 3, formulation of a long-term energy technological strategy is discussed. In Chapter 5, how to embody such a strategy is shown. (NEDO)

  17. Daylight and energy implications for CIE standard skies

    International Nuclear Information System (INIS)

    Li, Danny H.W.

    2007-01-01

    Recently, the International Commission on Illumination (CIE) has adopted a range of 15 standard skies, which include the existing CIE overcast, very clear and cloudless polluted skies, covering the whole probable spectrum of usual skies found in the world. The traditional daylight factor (DF) approach with the calculations being based on an isotropic overcast sky, however, cannot cater to the dynamic variations in daylight luminance and illuminance as the sun's position changes under non-overcast skies. Currently, we propose a numerical procedure that considers the changes in the luminance of sky elements to predict the interior daylight illuminance under the 15 CIE standard skies. This paper evaluates the method by using a typical room with a large vertical glazing window facing north. The available daylight for the room at mean hourly sun positions in each month in terms of DF and illuminance levels were determined and compared with those based on a computer program, namely, RADIANCE. A modification to the ground reflected component was made when a well defined shadow was cast in front of the window facade. It is shown that the results estimated by the proposed approach are in reasonably good agreement with those produced from RADIANCE. The interior daylight and lighting energy consumption were also determined using the proposed and the traditional DF approaches. The findings reveal that daylighting designs using existing CIE overcast sky only would considerably underestimate the indoor daylight availability and electric lighting energy savings, especially under high design indoor illuminance settings

  18. Distributional implications of higher energy prices in the UK

    Results presented are consistent with the claim that higher energy prices are regressive in impact in the UK. However, the size of the impact on the worst affected is not found to be as great as might be expected. It is not at all obvious that the size of impact established is such as to justify the use of terms such as fuel poverty or arguments for the subsidization of fuels purchased by those on low incomes. This is not to say that low income households in the UK have not in the last decade had serious problems with fuel bills. The evidence of, for example, the Supplementary Benefits Commission (1979) makes it obvious that large numbers of households have experienced real problems. However, from the evidence considered here, it is reasonable to suggest that the origin of such problems lies more with the technical characteristics of the consumption act, and with institutional arrangements for payment, in respect of heating and lighting, than with impact of higher fuel prices as such. Gas and electricity consumption is not readily monitored as use occurs, and payment is often by billing well after consumption. Casual observation suggests that the difficulties with fuel bills as reported to welfare agencies are predominantly difficulties with gas and electricity bills. The results also show that of the total impact of higher energy prices on cost of living indices, only 50% arises via the consumption of fuels in the home.

  19. Energy and the tax base: Implications for solar power

    Most local governments around the world derive their revenue from property taxation. In particular, councils can either tax buildings or rate land. At the local government level, this difference makes Melbourne a unique city to study. It is the only city in the world which uses different rating structures, side by side, to finance local government. One system rates land, (site value), the other taxes buildings. This has enabled extensive research to be undertaken, to determine the economic impact, if any, on the economy, and the change, if any, in rate-payer behaviour. The aim of this paper is to demonstrate that in implementing a change-over within society to the wider use of solar power, the tax system must also be addressed. Until the tax system is addressed, a change to renewable energy sources is unlikely within the next fifty years. The paper concludes that land use charges affect taxpayer behaviour. Taxes affect profits which affect economic decisions. The governing tax and economic laws will determine the energy decisions taken, and developments in the next seven years will lay the foundation for the next long term cycle.

    Commercial fisheries rely heavily on fossil fuel combustion and contribute heavily to the emission of atmospheric pollutants and greenhouse gases. Propulsion output of fishing vessels has continually increased from 30 kW in 1959 to nearly 320 kW in 2000, indicating that the Taiwanese fishing fleet tended to voyage farther and faster, and to adjust for the heavier loads demanded by more powerful fishing gear. Daily emissions from Taiwanese fishing vessels were estimated using output method. The marine fishery is unlikely to grow in the future as the government is implementing measures to ensure the development of sustainable fishing practices. There has been a rising trend in pollution to production ratios during the study period between 1959 and 2008. The ratio increased by 47% in the first decade, followed by fluctuations within the range of 50%-58% for the remainder of the statistical period. There is a need to investigate the possibility of reductions in all categories of fishing with regard to energy use and emissions through the subsidization of fishing vessels to encourage operators to switch to more energy efficient equipment and cleaner fuels. - Highlights: → Daily emissions from Taiwanese fishing vessels were estimated using output method. → We reported a steady increase in pollution to production ratio in Taiwan fishing industry. → We urged government and industry work together to ensure a transition to low carbon fishing.

    Full Text Available It is a great challenge for DC microgrids with stochastic renewable sources and volatility loads to achieve better operation performance. This study proposes an energy management strategy based on multiple operating states for a DC microgrid, which is comprised of a photovoltaic (PV array, a proton exchange membrane fuel cell (PEMFC system, and a battery bank. This proposed strategy can share the power properly and keep the bus voltage steady under different operating states (the state of charge (SOC of the battery bank, loading conditions, and PV array output power. In addition, a microgrids test platform is established. In order to verify the effectiveness of the proposed energy management strategy, the strategy is implemented in a hardware system and experimentally tested under different operating states. The experimental results illustrate the good performance of the proposed control strategy for the DC microgrid under different scenarios of power generation and load demand.

    The purpose of this paper is to provide an overview of future demand outlooks for energy, electricity and nuclear power, as a background for discussion of the design and operation aspects of advanced nuclear power systems. The paper does not attempt to forecast the actual outcomes of nuclear power programmes, since this will depend upon many factors that cannot be predicted with certainty. Rather, the paper outlines the size of the opportunity for nuclear power, in terms of the expected growth in energy and electricity demands, the need to diversify energy supply options and substitute depletable fossil fuels by other energy sources, and the need to mitigate health and environmental impacts including in particular those arising from the the atmospheric emissions from burning of fossil fuels. 7 refs

    In accordance with strategic planning in the military, the leader (in this case the Minister of Economy) is responsible for setting goals, finding the right people to accomplish these goals (those working in the energy sector), analysing the current situation (state of the energy sector) and evaluating available resources (conventional and renewable energy resources). In terms of economic planning (this term is proper for an economy that sets numerous laws and quotas), the goal is to get the Polish economy out of economic slump, which is the result of seventeen years of improper government practices, into a state of prosperity corresponding to no less than the European average. The only way of accomplishing this goal of high economic growth and catching up with highly-developed countries is to develop local inexpensive energy resources. This study focuses on the potential to develop abundant Polish geothermal resources as well as natural gas based co-generation. (author)

    The energy sector, with more than 800 billion Dollars annual turnover worldwide one of the most potent industries, is in for huge changes. Its structure and organization will become a different one altogether. New energy sources such as geothermal, wind and solar power need to be rendered accessible. The power industry needs to be transformed into a modern service industry in order to safeguard the sustainability of power generation. (orig.) [de

  9. Alternative energy development strategies for China towards 2030

    The purposes, objectives and technology path-ways for alternative energy development are discussed with the aim of reaching sustainable energy development in China. Special attention has been paid to alternative power and alternative vehicle fuels. Instead of limiting alternative energy to energy sources such as nuclear and renewable energy, the scope of discussion is extended to alternative technologies such as coal power with carbon capture and sequestration (CCS), electric and hydrogen vehicles. In order to take account of the fact that China's sustainable energy development involves many dimen-sions, a six-dimensional indicator set has been established and applied with the aim of comprehensively evaluating different technology pathways in a uniform way. The ana-lysis reaches the following conclusions: (a) in the power sector, wind power, nuclear power and hydro power should be developed as much as possible, while R&D of solar power and coal power with CCS should be strengthened continuously for future deployment. (b) in the transporta-tion sector, there is no foreseeable silver bullet to replace oil on a large scale within the time frame of 20 to 30 years. To ease the severe energy security situation, expedient choices like coal derived fuels could be developed. However, its scale should be optimized in accordance to the trade-off of energy security benefits, production costs and environmental costs. Desirable alternative fuels (or technologies) like 2nd generation biofuels and electrical vehicles should be the subject of intensive R&D with the objective to be cost effective as early as possible.

  11. Future strategies for oil shale development as a new indigenous energy resource in Jordan

    International Nuclear Information System (INIS)

    Jaber, J.O.; Tarawneh, T.

    2011-01-01

    Indigenous oil shale deposits could satisfy Jordan's demand for liquid and gaseous fuels as well as electricity for many centuries. Markets also exist for raw and retorted oil shale, spent shale, and for sulfur recovered during the upgrading and refining of crude shale oil. Although the potential benefits of oil shale development are substantial, complex and expensive facilities would be required, and these have serious economic, environmental, and social implications for the Kingdom and its people. In January 2006, the United States Trade and Development Agency (USTDA) awarded a grant to the Jordanian Ministry of Planning and International Cooperation to support the analysis of current oil shale processing technologies and the application of international expertise to the development of a oil shale industry in Jordan. The goal of the technical assistance project was to help the Government of Jordan (GoJ) establish short and long-term strategies for oil shale development and to facilitate the commercial production of shale oil in the country. This paper discusses the results of the project. The Kingdom's current energy situation and its previous work on oil shale are summarized, and the incentives and restraints on oil shale commercialization are described. Impediments to development are identified, and possible governmental responses are assessed. (author)

    Only an American, an old observer of the American scene, could make an analysis in depth of so complex a subject. The author bases his arguments on statistics and documents available to the public but, his conclusions only reflect his own personal opinion on the energy future of the United States. He shows the difficulties that the development of the nuclear programme has come up against since 1977 and the predictable economic and political effects. A new policy slows down the technological transfer, brings back into question the 'peaceful atom' and makes the task all the easier for the antinuclear movement. The nuclear future and public opinion after the Three Mile Island accident is an ever burning issue [fr

    Full Text Available Although Myanmar is among the world’s oldest oil-producing countries, Chinese oil and gas companies did not start their oil and gas exploration projects there until recently. The most recent and significant China–Myanmar energy cooperation project is the oil and gas pipelines which got started in 2009. This paper will discuss the reasons and driving forces for this pipeline project and its broader objectives, and testify whether pipelines can deepen regional economic integration and strengthen bilateral relations. This paper concludes by saying that China might use the China–Myanmar pipeline construction as an opportunity to play a more constructive role in Myanmar’s domestic reforms, thus improving its image in Southeast Asia and strengthening its relations with Myanmar.

    2016-01-01

    Highlights: • Many companies providing energy services are experiencing difficulties. • This research identifies key activities for the provision of energy services. • Findings are aggregated to the business-model level providing managerial insights. • This research identifies two different business model innovation paths. • Energy companies may need to renew parts of, or the entire, business model. - Abstract: Energy services play a key role in increasing energy efficiency in the industry. The key actors in these services are the local and regional energy companies that are increasingly implementing energy services as part of their market offering and developing service portfolios. Although expectations for energy services have been high, progress has so far been limited, and many companies offering energy services, including energy companies, are experiencing difficulties in implementing energy services and providing them to the market. Overall, this research examines what is needed for local and regional energy companies to successfully implement energy services (and consequently provide them to the market). In doing this, a two-stage process is used: first, we identify key activities for the successful implementation of energy services, and second, we aggregate the findings to the business model level. This research demonstrates that to succeed in implementing energy services, an energy company may need to renew parts or all of its existing product-based business model, formulate a new business model, or develop coexisting multiple business models. By discussing two distinct business model innovation processes, this research demonstrates that there can be different paths to success.

    2002-01-01

    The current Danish energy plan stipulates a production of 5 PI from energy crops in 2010. This may be attained through growing of either annual (e.g., cereal) or perennial energy crops (e.g., willow or Miscanthus). Existing Danish data and the IPCC methodology was used to calculate nitrous oxide emissions from and carbon sequestration in soils cropped with an annual energy crop (triticale) or a perennial energy crop (Miscanthus). The calculations for Miscanthus were performed separately for harvest in November or April, since the harvest time affects both yields and emissions. The estimates for Miscanthus were based on a 20-year duration of the cultivation period. The energy use for growing the crops was included in the energy budgets, as was the reduction in CO 2 emission that will result from substitution of fossil fuel (natural gas). The calculations were performed for both a coarse sandy soil and a loamy sand. The results were compared with current (reference) practice for growing cereals. There were only minor differences in production data and emissions between the two soil types. The area required to produce 5 PI was smallest for Miscanthus harvested in November (c. 25,000 ha), and about equal for triticale and Miscanthus harvested in April (c. 32,000 ha). The reduction in nitrous oxide emissions compared with cereal production was smallest for triticale (20 kt CO 2 equivalents /eq] yr -1 ) and about equal for Miscanthus at the two harvest times (30-36 kt CO 2 eq yr -1 ). Growing Miscanthus resulted in a carbon sequestration, with the highest rates (100 kt CO 2 eq yr -1 ) for Miscanthus harvested in April. The energy use for production of triticale was slightly lower than for normal cereal growing, whereas growing Miscanthus for harvest in April resulted in a smaller energy use which corresponded to an emission reduction of 20 kt CO 2 yr -1 . The substitution of fossil fuel corresponded to 285 kt CO 2 yr -1 . Summing all items, growing 5 PI worth of

  16. INCOME AND ENERGY SOURCES AMONG AGRARIAN HOUSEHOLDS IN NIGERIA: IMPLICATIONS FOR LOW CARBON ENERGY DEVELOPMENT IN LESS DEVELOPED COUNTRIES

    2012-07-01

    Full Text Available Low-carbon power comes from sources that produce fewer greenhouse gases than do traditional means of power generation. It includes zero carbon power generation sources, such as wind power, solar power, geothermal power and (except for fuel preparation nuclear power, as well as sources with lower-level emissions such as natural and petroleum gas, and also technologies that prevent carbon dioxide from being emitted into the atmosphere, such as carbon capture and storage. This article correlated value of income from different sources to energy sources used by agrarian households in Nigeria and drew implications for low carbon development in Africa. It analysis included use of wind power for irrigation purposes, harnessing solar energy for lightening and possible cost implications. Secondary data were collected from Community Based Monitoring System Nigeria Project. Descriptive statistics, correlation and qualitative analysis were employed. The average annual income of agrarian households from different sources such as crop farming, livestock farming, petty trading, forest exploitation, remittance and labour per day was below the poverty line of $1 per day. The source of energy that had the highest number of significant correlation was electrical energy (low carbon electrical energy. It showed the possibility of pooling resources as farmers group to attract grants or equity financing to build wind mills for irrigation. The study recommended use of energy efficient bulbs to reduce CO2 emissions. This requires creating awareness among rural dwellers of the need to make such change.
