    At the beginning of 2003 the French government launched a national debate about the energies. 6 conferences are due to be held during the first semester. The opening conference in Paris was dedicated to the distribution of energy resources in the world, to the struggle against climate warming and to the opening and deregulation of markets. The following conferences that will take place in Strasbourg, Nice, Bordeaux and Rennes will focus on topics such as controlling the energy consumption in industries, companies and households, and reviewing the pros and cons of the different sources of energy. The ending conference will be held in Paris, the participants will try to find consistencies in the previous debates and will draw some conclusions that will help the French authorities to define the next energy policy.

    Renewable energy is an important piece of the puzzle in meeting growing energy demands and mitigating climate change, but the potentially adverse effects of such technologies are often overlooked. Given that climate and ecology are inextricably linked, assessing the effects of energy technologies requires one to consider their full suite of global environmental concerns. We review here the ecological impacts of three major types of renewable energy - hydro, solar, and wind energy - and highlight some strategies for mitigating their negative effects. All three types can have significant environmental consequences in certain contexts. Wind power has the fewest and most easily mitigated impacts; solar energy is comparably benign if designed and managed carefully. Hydropower clearly has the greatest risks, particularly in certain ecological and geographical settings. More research is needed to assess the environmental impacts of these 'green' energy technologies, given that all are rapidly expanding globally. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Since the event of Niigataken Chuetsu-oki Earthquake in 2007 and the subsequent press reports on damage of nuclear power station after it, a stance of media is being questioned. In order to clear this problem, basic organizational structure of the press related to nuclear energy news was analyzed. Local news department, social news department, science news department and economical news department involve in nuclear energy news the accordance with their own situations and concerns. This structure makes problem of nuclear energy news reporting complicated. Changing this system is required but very difficult. It is concluded that the press problem around nuclear energy news is strange. (author)

  8. Green energy in Europe: selling green energy with green certificates

    Ouillet, L.

    2002-01-01

    Sales of green power products are booming in Europe: 50,000 customers in the United Kingdom, 775,000 in the Netherlands and 300,000 in Germany. Laws of physics are however formal: the way in which electricity flows within the grid does not allow suppliers to assure customers that they are directly receiving electricity produced exclusively from renewable energy sources. What are marketers selling their customers then? Laetitia Ouillet, Greenprices, takes a closer look and focuses on the potential of selling green energy in the forms of renewable energy certificates.

    Firms offering a Green electricity product have discovered that residential customers are willing to pay extra for the assurance that their electricity is generated through the use of non-polluting or renewable resources. This research investigated the market potential for Green energy at the next level of the energy consuming chain, commercial establishments at which small and medium sized businesses interface with customers. Green energy is proving to be an attractive proposition to some consumers in the residential marketplace. Is there a possibility that Green energy can also be sold to commercial enterprises? This research project sought to answer this question and to investigate the factors that might lead small business people to opt for Green. Answers to these questions will help energy companies target the businesses most likely to accept Green power with the right product set and product features

  12. Green Energy - Fiction and Reality

    Science.gov (United States)

    Cranberg, Lawrence

    2009-03-01

    The term ``Green Energy'' has been popularized to refer to energy sources that do not depend on fossil fuels. The oldest truly ``green'' energy source is wood fuel derived by photosynthesis for thermal comfort in the cold season. Thermal energy from the combustion of wood for personal heating in our 41 million fireplaces has greatly declined, due to an ``Anti-fireplace Hoax'' (1) that fireplaces are ``energy counterproductive.'' Physicists have a special obligation to address the problem that our major true source of ``Green Energy'' is widely misrepresented and neglected. 1. L.

    2010-01-01

    The first step towards the widespread use of renewable energy sources and preservation of our environment for the people of the future is to adopt the ''green accounting'' standards that translate socially and environmentally responsible behavior into monetary terms, the only language businesses understand. These standards have the potential of switching on the red light for all pollution-causing power plants, and those depleting the natural capital in any way, be it over-harvesting the forests, or exhausting the underground treasures - coal, oil, natural gas, etc. This paper will show how green accounting can help in changing the focus from the economic welfare to the total societal welfare, acknowledging the fact that human society is an integral part of the natural world. The paper will also briefly present the software developed by the authors that introduce the green accounting principles into the investment appraisal process, aiming at encouraging investments into renewable energy. The tool is also useful as a platform facilitating calibration of economic/financial instruments, like environmental taxes of governmental incentives, that are usually to boost renewable energy sector. The comparative analysis of investment into biofuel-powered combined heat and power production plant using two types of investment valuation standards, one based on conventional cash-flow analysis, the other based on green-accounting standards is detailed in the paper. The analysis is performed as a part of the European Commission Framework Program Project AFTUR, undertaken by the consortium consisting of respectful European Research Establishments in renewable energy area as well as major European biofuel-powered turbine producers. The results show that the wider adoption of green accounting standards would induce the unprecedented growth of the renewable energy sector, because it would make the investment into renewable energy attractive for investors.

    Renewable, CO 2 -free or clean energies are receiving the adhesion of politicians and investors. 21.5 billion dollar were invested in 2006 in new renewable energy production capacities at the world scale, indicating a real craze for a structuring industry which would carry on its growth. Many companies are now quoted at the stock exchange and this trend should increase with the competition of emerging countries, like China and India, in this sector. The need for new technologies remains important and the R and D budget reached 16.3 billion dollars at the world scale in 2006. The market of renewable equipments and facilities should quadruple in the next 10 years and should reach 226.7 billion dollars in 2016. (J.S.)

  16. Green energy strategies for sustainable development

    International Nuclear Information System (INIS)

    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

    When specialists get together to discuss their subject, they usually concentrate on their problems. This, if done constructively, can be useful, but it provides outsiders with an unbalanced view of the subject. The problems are then amplified by the media, which provide much better coverage of bad news than good news. For instance, in papers on global energy, economists have stressed the difficulties in raising capital, not only for new energy systems but for any worthwhile project. Restating the problem is no help; what is needed of economists are solutions. Fortunately, for the technical problems of energy supply, there are solutions, one of which is nuclear energy. Futhermore, some of the solutions are not just economically acceptable, they could be economically beneficial

    The Green Mines green energy research project was initiated by the CANMET Mining and Mineral Sciences Laboratories of Natural Resources Canada. The objective of the initiative was to demonstrate that organic residuals could be used to remediate mine tailings and establish agriculturally productive land where energy crops such as corn, canola, soy, switchgrass and other species could be grown and harvested specifically as feedstock for the production of green fuels. This paper discussed the scope and progress to date of the Green Mines green energy project. This included discussion about a column leaching study and about effluent treatability and toxicity. Neutralization test results and the results of field trials were presented. The paper concluded with a discussion of next steps. An advisory committee has been established to review annual progress and establish research directions. Overall, preliminary results from the column study suggest that sulphate reduction at the tailings-biosolids interface is occurring, although steady state has not yet been reached after more than one year of testing. 1 tab., 3 figs.

  8. The challenge of greening energy systems

    Joseph, A.; Hughes, L.

    2006-01-01

    The current state of world energy supply and demand was examined along with future challenges facing population growth, economic growth, energy-demand growth, fossil energy supply, technology improvements, renewable energy solutions, and conservation measures. It was suggested that in order to implement cleaner and greener energy technology, it is important to understand the nature of global energy systems. The challenge of defining the related ideologies of green energy and sustainability was discussed. In this paper, green energy was defined as indicating environmental compatibility with little or no negative environmental impact. This differs from the concept of sustainability, which was defined as an action that can be repeated continuously without depleting or diminishing resources. In general, green energy options include most technologies that do not involve fossil fuels. However, this paper considered a spectrum of shades of green with some options being low-impact and cleaner, and others having high environmental impacts. As an example, the authors presented the ongoing debate over nuclear energy and hydro power. Although both energy sources can be sustainable over hundreds of years, they may or may not be environmentally compatible because they are often considered to have problematic attributes. Energy from renewable sources currently accounts for less than 20 per cent of world primary energy supply because price and implementation challenges in the renewables sector do not generally compare well to other energy sources. With high energy-demands beginning to strain finite fossil-energy supplies, the energy sector is now subject to more frequent disruptions and price fluctuations. Future growth from emerging economies will demand more energy and resources. This paper also emphasized that the proportion of green sources of energy has not increased substantially in the past 3 decades, and despite many technological advances, there continue to be significant

    Tribology is the study of friction, wear and lubrication. Recently, the concept of “green tribology” as “the science and technology of the tribological aspects of ecological balance and of environmental and biological impacts” was introduced. The field of green tribology includes tribological technology that mimics living nature (biomimetic surfaces) and thus is expected to be environmentally friendly, the control of friction and wear that is of importance for energy conservation and conversion, environmental aspects of lubrication and surface modification techniques, and tribological aspects of green applications such as wind-power turbines or solar panels. This book is the first comprehensive volume on green tribology. The chapters are prepared by leading experts in their fields and cover such topics as biomimetics, environmentally friendly lubrication, tribology of wind turbines and renewable sources of energy, and ecological impact of new technologies of surface treatment.

    Skillful predictions of water and energy cycle extremes (flood and drought) are elusive. To better understand the mechanisms responsible for water and energy extremes, and to make decisive progress in predicting these extremes, the collaborative NASA Energy and Water cycle Extremes (NEWSE) Integration Project, is studying these extremes in the U.S. Southern Great Plains (SGP) during 2006-2007, including their relationships with continental and global scale processes, and assessment of their predictability on multiple space and time scales. It is our hypothesis that an integrative analysis of observed extremes which reflects the current understanding of the role of SST and soil moisture variability influences on atmospheric heating and forcing of planetary waves, incorporating recently available global and regional hydro- meteorological datasets (i.e., precipitation, water vapor, clouds, etc.) in conjunction with advances in data assimilation, can lead to new insights into the factors that lead to persistent drought and flooding. We will show initial results of this project, whose goals are to provide an improved definition, attribution and prediction on sub-seasonal to interannual time scales, improved understanding of the mechanisms of decadal drought and its predictability, including the impacts of SST variability and deep soil moisture variability, and improved monitoring/attributions, with transition to applications; a bridging of the gap between hydrological forecasts and stakeholders (utilization of probabilistic forecasts, education, forecast interpretation for different sectors, assessment of uncertainties for different sectors, etc.).

    2000-01-01

    Kyoto Protocol is the first global commitment to reduce greenhouse gas (GHG) emissions. Malaysia, which signed the Protocol on 12 March 1999, must also take steps to address the climate change concerns. The use of renewable energy sources is seen as a feasible way to address the issue. Despite their environment-friendliness, these sources of energy are grossly under-utilised even though Malaysia is amply endowed with renewable energies, particularly biomass and solar. As a unique domestic resource, recurring energy savings from energy efficiency could also qualify as renewable energy. At present, the contribution of renewable energy in the country's energy mix is very small compared to its large potential. The Malaysian Government recognizes the potential of this form of energy. As part of its fuel diversification policy, the government plans to expand the four-fuel strategy to include renewable energy as the fifth fuel. Due to all year constant sunshine and vast oil palm cultivation, both solar and palm oil residues are identified as the most promising green energy option. Efforts are underway to embark on programs to demonstrate and evaluate the viability of these emerging green technologies. A few organizations are given grants to undertake pre-feasibility studies of pre-commercialization demonstration projects. When approved, viable projects could also qualify for technical and financial assistance from foreign partners. However, grants are limited and under World Trade Organization rules such subsidies should not exceed 30 percent in most cases. Commercialization of green energy projects must therefore involve full participation of private developers and financial institutions. Yet, virtually no attempt is made to promote financing of such projects in Malaysia. In most cases, financial institutions are not aware of the economic potential of these unique and under exploited sources. This paper will discuss problems in financing green energy projects and then

  2. Hydrogen - A new green energy

    International Nuclear Information System (INIS)

    Barnu, Franck

    2013-01-01

    A set of articles proposes an overview of the role hydrogen might have as energy in the energy transition policy, a review of different areas of research related to the hydrogen sector, and presentations of some remarkable innovations in different specific fields. Hydrogen might be an asset in energy transition because production modes (like electrolysis) result in an almost carbon-free or at least low-carbon hydrogen production. Challenges and perspectives are evoked: energy storage for intermittent energies (the MYRTE platform), the use of a hydrogen-natural mix (GRHYD program), the development of fuel cells for transport applications, and co-generation (Japan is the leader). Different French research organisations are working on different aspects and areas: the H2E program by Air Liquide, fuel cell technologies by GDF Suez, power electrolyzers and cells by Areva. Some aspects and research areas are more specifically detailed: high temperature electrolysis (higher efficiencies, synthesis of methane from hydrogen), fuel cells (using less platinum, and using ceramics for high temperatures), the perspective of solid storage solutions (hydrogen bottles in composite materials, development of 'hydrogen sponges', search for new hydrides). Innovations concern a project car, storage and production (Greenergy Box), the McPhy Energy storage system, an electric bicycle with fuel cell, easy to transport storage means by Air Liquide and Composites Aquitaine, development of energy autonomy, fuel cells for cars, electrolyzers using the Proton Exchange Membrane or PEM technology

    On March 8, 2006, EU Commission president Jose Manuel Barroso and Energy Commissioner Andris Piebalgs presented to the public the Green Paper on 'A European Strategy for a Sustainable, Competitive, and Secure Energy', which had been expected for some time. The authors thus underscore the great importance for European development of energy policy. However, the European treaties restrict the competence of the EU in matters of energy policy. The Green Paper is to spark off a broad consultation and discussion process about the potential design of a comprehensive European energy policy. 6 main areas are mentioned in which action needs to be taken: - Energy for growth and employment. - Single energy market and continuity of supply. - Mix of energy resources: sustainable, efficient, divers. - Climate protection. - Innovation in energy technologies. - Coherent foreign policy in matters of energy. 3 key objectives are identified: - Development of renewable and other energy sources also with low CO 2 emissions. - Opening of markets, promotion of investments, energy efficiency. - Continuity of supply.

    Municipal governments and provincial regulators are under increasing pressure to divert clean organic waste materials from landfill sites and establish productive uses for them. This article described the Natural Resources Canada (NRCan) CANMET Green Mines Green Energy consortium. Composed of mining, forestry, government, and academic representatives, the consortium's aim is to expand the use of organic waste residuals in the rehabilitation of mine sites for use as a feedstock in biofuel production. The program's themes include: (1) determining the conditions required to maximize growth; (2) investigating the interaction of various organic covers on tailings pore water, effluent and mineralogy; (3) investigating the potential economic and environmental impacts on all relevant sectors; and (4) disseminating findings to all relevant stakeholders. Tests are currently being conducted to determine the potential impact of municipal waste materials on tailings oxidation and effluent chemistry. The effect of biosolids and compost-derived dissolved organic carbon on effluent treatability and toxicity is also being investigated. Results from the investigations to date suggest that sulfate reduction at the tailings-biosolids interface is taking place. It was concluded that steady state has not yet been reached after a 1 year period. 10 refs., 1 tab., 7 figs.

    Governmental influence on public utilities and on the government-controlled nuclear industry so far has been much stronger than in the Federal Republic. This influence was cut back considerable when denationalization pursuant to the Electricity Act 1989 took effect, but not for the nuclear industry. Despite governmental declarations to the contrary, the big reactor building program has shrunk to one started reactor being finished. The reasons for turning away from nuclear energy are not so much to be found with the greens, who have little influence because of majority suffrage, but with orientating at short-term maximization of profits as a result of the denationalization process which prevents at present the realization of financing large-scale projects in the field of nuclear energy on a long-term basis. With the Magnox reactors coming to the end of their working life and neither coal-fired power stations nor nuclear power plants being built, with the exception of Sizewell II, this situation will sooner or later lead to an out-of-date power plant pool, and considerations concerning power plant capacities (including nuclear reactors) will become necessary. As regards reprocessing, the abandonment of Wackersdorf has led to the Internal Market being already anticipated by long-term contracts concluded with BNF. (orig./HSCH) [de

    Full Text Available EU has to attain the strategic objectives for 2020: 20% of energy from renewable sources, cutting the emissions of greenhouse gases by 20% and diminishing the dependence on imported fuels, that is why in the last years European Commission has decided that MS should increase the flexibility of programs to promote green energy and cut subsidies. Although wind and solar energy have become more competitive in terms of cost in the last two decades, many production technologies need to be improved, also storage and transport capacities. Romania has an important potential of renewable energy resources and has introduced a functional mechanism for supporting their development based on a system of mandatory quotas for electricity, combined with trading a number of green certificates, but all the costs are transferred to the consumers.This system may carry an overcompensation for the investors and also an excessive burden on the consumers. Most investments were made in wind and hydro, the fewest in solar and biomass. Market liberalization may create more competition and stimulate the investments in different renewable resources.

    We present the findings of a choice experiment designed to estimate consumer preferences and willingness-to-pay (WTP) for voluntary participation in green energy electricity programs. Our model estimates WTP for a generic 'green energy' source and compares it to WTP for green energy from specific sources, including wind, solar, farm methane, and biomass. Our results show that there exists a positive WTP for green energy electricity. Further, individuals have a preference for solar over a generic green and wind. Biomass and farm methane are found to be the least preferred sources

    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

    Greening of industry is a prominent topic on the European agenda and has received a new impetus with the Kyoto process, where the European Union and its member states are facing new obligations. Due to its role as a major infrastructure sector and due to its extensive emissions, the electricity sector has become a focal industry in this context. These same factors, as well as the large public ownership has, in fact, traditionally placed energy in a central public political focus. The energy and electricity sector hence exemplify the intertwined nature of economics and politics in sector developments, where technology choices and capacity expansions have numerous motivations and diverse interests to please. This report discusses ''green'' innovation in the energy industry. By selecting some of the most advanced examples of breakthrough for new green technologies in Europe, it explores the basic elements of successful greening of industry. To account for the fact that product innovation- and diffusion-processes are embedded in a complex politico-economic setting, we have developed an analytical framework, incorporating both economic, political and societal elements and the interplay between them. More specifically, environmentally oriented innovation is seen as evolving out of the interplay between: 1) a technical-commercial core (major market agents, i.e. the renewable energy supply industry, associated complementary industries and consumers); 2) the political-administrative system; and 3) the societal basis, referring to existing societal customs, norms, and modes of social organisation. Drawing on Porter's (1990) analysis of business clusters, we have termed our focus ''green energy-industrial cluster'' emergence and growth. We have taken Porter's attempt to break out of a limited market analysis into a broader strategic focus one step further, where the political and institutional dimensions are more explicitly included.

    The Green Energy Plan indicates how the ambitious climate targets of the cabinet can be achieved at the lowest cost. Main issue is that all energy consumers individually (industry, electricity production, aviation) or collectively (built environment, transport) are placed in an emission credits system with climate budget. The effort and costs are differentiated in order to ensure a largest possible acceptance. Moreover, new standards will be introduced for vehicles, buildings (existing and new) and appliances. The effects of the plan have been calculated and will lead to the desired halving of greenhouse gas emissions, an annual efficiency improvement of 2.1%. In 2030 the annual cost will amount to over 4 billion euro, but there are also substantial social benefits. This background report focuses on households, utilities and SME, greenhouse farming, traffic, industry, electricity, renewable energy, biomass and biodiversity, CO2 storage, external costs and benefits of Green4Sure, employment and socio-economic effects as well as the climate act. [mk]. [Dutch] Het Groene Energieplan geeft aan hoe de ambitieuze klimaatdoelen van het kabinet gehaald kunnen worden tegen de laagste kosten. Belangrijkste punten zijn dat alle energiegebruikers individueel (industrie, elektriciteitsproductie, luchtvaart) of collectief (gebouwde omgeving, transport) onder een emissierechtensysteem met klimaatbudget komen te vallen. De inspanningen, en daarmee de kosten zijn gedifferentieerd om de acceptatie zo groot mogelijk te laten zijn. Daarnaast komen er normen voor voertuigen, gebouwen (nieuw en bestaand) en apparaten. De effecten van het plan zijn doorgerekend en leiden tot de gewenste halvering van de broeikasgassen, een jaarlijkse efficiencyverbetering van 2,1%. De kosten bedragen in 2030 jaarlijks ruim 4 miljard euro, maar er zijn ook forse maatschappelijke baten.

    High-purity hydrogen gas was generated from the chemical reaction of aluminum with sodium hydroxide. Several molar relations of sodium hydroxide/aluminum were investigated in this study. The experimental results showed that hydrogen yields are acceptable and its purity was good enough to be used in a proton exchange membrane (PEM) fuel cell to produce electricity. An estimation of the amount of energy produced from the reaction of 100 aluminum cans with caustic soda showed that the hydrogen production is feasible to be scaled up to reach up to 5kWh in a few hours. This study is environmentally friendly and also shows that green energy can be produced from aluminum waste at a low cost.

    Peters, R.; Whitmore, J.; Shariff, N.

    2005-11-01

    This green paper was created by the Canadian Environmental Network to initiate a dialogue on climate change and energy issues. Recommendations for energy strategies for Canada beyond 2012 were presented. An overview of recent climate science was presented, as well as various stabilization scenarios needed to prevent further climate change. A review of global energy trends working for and against action to prevent climate change was also provided. It was suggested that the stabilization of greenhouse gas (GHG) concentrations can only be achieved when the United States and large developing economies such as China, India and Brazil transform themselves into renewable-energy based economies. Renewable energy and energy efficiency must play a central role in future climate change regimes. It was suggested that nuclear power cannot be considered as an option to reduce GHGs due to its high cost, and on-going public concerns over long-term waste disposal, fuel-cycle health and safety. A viable global framework for stabilizing GHG concentrations built on the current regimes of the United Nations Framework Convention on Climate Change and the Kyoto Protocol was recommended. It was suggested that richer industrialized nations must take the lead by pursuing absolute reductions and providing assistance to developing nations for mitigation and adaptation to climate change. It was recommended that developing nations should contribute to global mitigation efforts by pursuing low-carbon intensity development paths, and that effective climate change policies must address the economic barriers faced by developing nations. Other recommendations included a regulatory regime for major energy producers and users incorporating progressively lower GHG emission targets; the elimination of all subsidies for the fossil fuel and nuclear fuel-cycle and power industries; the adoption of a national renewable energy strategy; the implementation of a national energy conservation and efficiency

    Since 2006, massive shale gas exploration and development in the United States has enabled the country to reduce the price of gas by a factor of 3. Taking instantaneously advantage of this unique situation, the chemical sector has planned more than 100 billion dollars of investment in new industrial capacity, creating a tremendous environment for its domestic chemical industry. In Europe, despite a high capacity for innovation, the chemical industry is suffering from ageing facilities and high production costs. It must contend with ferocious competition from the United States but also from Asia, which currently represents 46% of the global market, and the Middle East that is benefiting from the 50 billion dollars invested in the chemical sector since the early 2000's. Lower energy prices and labor costs in the United States are negatively impacting the competitiveness of European industrial companies but their capacity to innovate can help them to re-bounce. By reducing the environmental impact of their products, they can generate added value that is important to their direct customers, end users and also governments. In this article, to assist industrial companies, ENEA, a consulting firm specialized in energy and sustainable development, examines two strategic principles of green chemistry: energy efficiency and the use of renewable feedstock. It addresses all of the topics linked to energy and carbon in chemistry, from supply (bio-feedstocks, CO 2 reuse) to the end products (life-cycle analysis, recyclability) while also covering the processes (energy sobriety, bio-refineries, use of microalgae)

  8. Green power: A renewable energy resources marketing plan

    Barr, R.C.

    1997-01-01

    Green power is electricity generated from renewable energy sources such as power generated from the sun, the wind, the heat of the earth, and biomass. Green pricing is the marketing strategy to sell green power to customers who voluntarily pay a premium for it. Green pricing is evolving from the deregulation of the electric industry, the need for clean air, reflected in part as concern over global warming, and technology advances. The goal of the renewable energy marketing plan is to generate enough revenues for a utility to fund power purchase agreements (PPAs) with renewable energy developers or construct its own renewable facilities. Long-term, fixed price PPAs enable developers to obtain financing to construct new facilities, sometimes taking technological risks which a utility might not take otherwise. The marketing plan is built around different rate premiums for different categories of ratepayers, volunteer customer participation, customer participation recognition, and budget allocations between project costs and power marketing costs. Green prices are higher than those for conventional sources, particularly prices from natural gas fired plants. Natural gas is abundant relative to oil in price per British thermal unit (Btu). Green pricing can help bridge the gap between the current oversupply of gas and the time, not far off, when all petroleum prices will exceed those for renewable energy. The rapid implementation of green pricing is important. New marketing programs will bolster the growing demand for renewable energy evidenced in many national surveys thus decreasing the consumption of power now generated by burning hydrocarbons. This paper sets forth a framework to implement a green power marketing plan for renewable energy developers and utilities working together

    With the seriousness of environmental issues and the shortage of resources, the applicability of green energy technology has been paid more and more attention by scholars in different fields. However, the current researches are often single in perspective and simple in method. According to the Theory of Applicable Technology, this paper analyzes and defines the green energy technology and its applicability from the all-around perspectives of symbiosis of economy, society, environment and science & technology etc., and correspondingly constructs the evaluation index system. The paper further applies the Fuzzy Comprehensive Evaluation to the evaluation of its applicability, discusses in depth the evaluation models and methods, and explains in detail with an example. The author holds that the applicability of green energy technology involves many aspects of economy, society, environment and science & technology and can be evaluated comprehensively by an index system composed of a number of independent indexes. The evaluation is multi-object, multi-factor, multi-level and fuzzy comprehensive, which is undoubtedly correct, effective and feasible by the Fuzzy Comprehensive Evaluation. It is of vital theoretical and practical significance to understand and evaluate comprehensively the applicability of green energy technology for the rational development and utilization of green energy technology and for the better promotion of sustainable development of human and nature.

    2014-01-01

    The advancement of business and social practices based on information and social practices based on information and communication technologies (ICTs) in the last few decades has transformed many, if not most, economies and businesses into e-economies and businesses into e-businesses. For economies, ICTs are increasingly playing a critical role in transforming and generating economic opportunities. Technology has a potential to create sustainable business and society both in grim and green economic times. Especially, the recovery from the current economic crisis is going to lead to more greener and energy efficient industries. Data centers are found to be major culprits in consuming too much energy and generating higher level of CO/sub 2/ in their overall operations. In order to handle the sheer magnitude of today's data, servers have become larger, denser, hotter, and significantly more costly operate using more power than being used earlier. This paper determines the properties and attributes of green IT infrastructures and the way they will be helpful in achieving green sustainable businesses. The proposed attributes and characteristics of green IT using Virtualization technology are very productive and efficient and green, hence reducing the emission of greenhouse gases so that their overall effect on global warming can be reduced or even eliminated. The proposed attributes indicate the qualities of green IT to enhance the proper utilization of hardware and software resources available in the data center. (author)

    2013-09-01

    Full Text Available Nowadays the growth of the cities increased built and paved areas, energy use and heat generation. The phenomenon of urban warming, called urban heat island, influences negatively outdoor comfort conditions, pollutants concentration, energy demand for air conditioning, as well as increases environmental impact due to the demand of energy generation. A sustainable technology for improving the energy efficiency of buildings is the use of green roofs and walls in order to reduce the energy consumption for conditioning in summer and improve the thermal insulation in winter. The use of green roofs and walls can contribute to mitigate the phenomenon of heat island, the emissions of greenhouse gases, and the storm water runoff affecting human thermal comfort, air quality and energy use of the buildings. Recently, a number of municipalities started to adopt regulations and constructive benefits for renovated and new buildings which incorporate green roofs and walls. The aim of this paper is to describe the green roofs and walls plant technology.

    Highlights: • We estimated green energy production in a municipal wastewater treatment plant. • Engineered approaches in mining multiple green energy resources were presented. • The estimated green energy production accounted for 6.5% of energy independence in the plant. • We presented practical information regarding green energy projects in water infrastructures. - Abstract: Increasing energy prices and concerns about global climate change highlight the need to improve energy independence in municipal wastewater treatment plants (WWTPs). This paper presents methodologies for estimating the energy independence of a municipal WWTP with a design capacity of 30,000 m 3 /d incorporating various green energy resources into the existing facilities, including different types of 100 kW photovoltaics, 10 kW small hydropower, and an effluent heat recovery system with a 25 refrigeration ton heat pump. It also provides guidance for the selection of appropriate renewable technologies or their combinations for specific WWTP applications to reach energy self-sufficiency goals. The results showed that annual energy production equal to 107 tons of oil equivalent could be expected when the proposed green energy resources are implemented in the WWTP. The energy independence, which was defined as the percent ratio of green energy production to energy consumption, was estimated to be a maximum of 6.5% and to vary with on-site energy consumption in the WWTP. Implementing green energy resources tailored to specific site conditions is necessary to improve the energy independence in WWTPs. Most of the applied technologies were economically viable primarily because of the financial support under the mandatory renewable portfolio standard in Korea

  18. Obama: towards an energy green new deal?

    International Nuclear Information System (INIS)

    2009-09-01

    After the announcement of the very ambitious 'New Energy for America' plan, the author comments what could change, and what may not change in the U.S. energy policy. He recalls that most of the previous American presidents stressed a necessary energy independence which, in fact, has never been reached. He indicates that energy consumption per capita is particularly high in this country as well as greenhouse gas emissions which has been increasing during the last decades. The author highlights the heterogeneous situations which can be observed among the different states in terms of sources of energy and of electricity import. This heterogeneity renders rather difficult to reach a consensus on issues like carbon dioxide market. Then, the author discusses the influence of climate change on public awareness. In the second part of the article, the author discusses the relationship between energy consumption and economic growth in an historical perspective. He notices that some efforts in energy saving may finally result in an increase of energy consumption, that which questions the American way of life

    2012-01-01

    The policy context for green energy laws in the United States has changed over the past few years, because the Republican Party has increasingly opposed renewable electricity and other green energy policies. In this study, we draw on a database of 6071 votes on RPS (renewable portfolio standards) and PACE (Property-Assessed Clean Energy) laws by individual state legislators in the United States to examine the circumstances shaping Republican votes for green energy laws from 2007–2011. We find that votes on these laws are indeed increasingly partisan, with Republicans supporting RPS laws especially less than Democrats. However, Republicans' support for these laws is higher in states with weaker fossil fuel industries. Furthermore, Republicans tend to support the laws where median household income is lower, environmental organizations are weaker, labor-environmental coalitions are absent, and the proportion of Democrats in the legislature is lower, suggesting a reactive effect against green energy policies in more progressive settings. - Highlights: ► We analyze Republican votes for state RPS and PACE laws from 2007–2011. ► Support for RPS laws declined, while support for PACE laws remained steady. ► Support for both laws is lower in states with strong fossil fuel industries. ► Support for both laws is lower in more Democratic legislatures.

    2016-12-14

    Manipulating the flow of energy in nanoscale and molecular photonic devices is of both fundamental interest and central importance for applications in light energy harvesting optoelectronics. Under erratic solar irradiance conditions, unregulated power fluctuations in a light-harvesting photocell lead to inefficient energy storage in conventional solar cells and potentially fatal oxidative damage in photosynthesis. Here, we compare the theoretical minimum energy fluctuations in nanoscale quantum heat engine photocells that incorporate one or two photon-absorbing channels and show that fluctuations are naturally suppressed in the two-channel photocell. This intrinsic suppression acts as a passive regulation mechanism that enables the efficient conversion of varying incident solar power into a steady output for absorption over a broad range of the solar spectrum on Earth. Remarkably, absorption in the green portion of the spectrum provides no inherent regulatory benefit, indicating that green light should be rejected in a photocell whose primary role is the regulation of energy flow.

  2. Doing more with less. green paper on energy efficiency

    International Nuclear Information System (INIS)

    2005-01-01

    Even without high and volatile oil prices, which have led to a downgrading of the prospects of economic growth in Europe, there would be very good reasons for the European Union to make a strong push towards a re-invigorated programme promoting energy efficiency at all levels of European society. This green paper seeks to act as a catalyst, leading to a renewed energy efficiency initiative at all levels of European society - EU, national, regional and local. Furthermore, this Green Paper seeks to make a significant contribution, by way of example and leadership, to kick-start an international effort to contribute to addressing climatic change through energy efficiency. China presently uses more than five times as much energy as the EU to produce one unit of GDP, USA uses approximately 50% more than EU. With exploding energy demand, in particular in China and India, energy efficiency must be one of the key policies to try to reconcile, on the one hand, the increased energy needs of the developing world to power growth and improve living conditions and, on the other hand, combat global warming. This Green Paper, and the momentum created in following it up, should put the EU at the forefront of efforts to make energy efficiency a global priority. (BA)

In doing so, we consider both demand-pull effects, which induce innovative activity by increasing the expected value of innovations, and technology-push effects, which drive innovative activity by extending the technological capability of an economy. Our analysis is conducted using patent data from the European Patent Office on a panel of 26 OECD countries over the period 1978-2009. Utilizing a dynamic count data model for panel data, we analyze 11 distinct green energy technologies. Our results indicate that the existing knowledge stock is a significant driver of green energy innovation for all technologies. Furthermore, the results suggest that energy prices have a positive impact on innovation for some but not all technologies and that the e.ect of energy prices and technological knowledge on green energy innovation becomes more pronounced after the Kyoto protocol agreement in 1997.

    Between 1990 and 2004, greenhouse gas (GHG) emissions from the residential sector have grown by 10 per cent, and are likely to continue growing unless a policy aimed at reducing emissions is introduced. The residential sector is a significant contributor to Canada's overall GHG emissions, and an important source for potential reductions. This report presented the results of a study that described and evaluated a new economic instrument aimed at reducing greenhouse gas (GHG) emissions and energy consumption in Canada from household appliances, such as air conditioners, furnaces and boilers. Results of a quantitative analysis to determine the effect of changing taxation of residential appliances to reflect energy consumption and greenhouse gas emissions were presented. In addition, the report presented the results of a qualitative evaluation of the policy, using the criteria established in the 2005 budget plan, a framework for evaluating environmental tax proposals. The report outlined the context for the tax proposal that was evaluated and provided a summary of trends in Canada's greenhouse gas emissions and energy consumption as well as a discussion of important trends in residential energy consumption. A review of policies already in place to address energy consumption from household appliances was also presented. 11 tabs., 6 figs

    In liberalized electricity markets, suppliers are offering several kinds of voluntary green electricity products marketed as environmentally friendly. This paper focuses on the development of these voluntary markets at household level in the UK, Germany and Finland. Since there are already existing renewable energy policies regulating and encouraging the use of renewable energy, it is important to consider whether voluntary products offer real additional benefits above these policies. Problems such as double counting or re-marketing hydropower produced in existing plants are identified. According to our study, the demand varies between countries: in Germany the number of green electricity customers has increased and is also higher than in the UK or Finland. Typically the average additional cost to consumer from buying green electricity product instead of standard electricity product is in the range of 0-5% in all studied countries, although the level of price premium depends on several factors like electricity consumption. Case study of Finland and literature show that the impacts of green energy are not solely environmental. Renewable energy can benefit local public policy.

    Full Text Available Social news, unlike video games or TV programs, conveys real-life interactions. Theoretically, social news in which people help or harm each other and violate rules should influence both prosocial and violation behaviors. In two experiments, we demonstrated the spreading effects of social news in a social interaction context emphasizing social conventions and a nonsocial interaction context emphasizing moral norms. Across the two studies, the results showed that positive social news increased cooperation (decreased defection but had no effect on cheating, whereas negative social news increased cheating but with no change in cooperation (or defection. We conclude that there is a spreading impact of positive social news in the conventional norm domain and of negative social news in the moral norm domain.

    The goal of the Green Mines green energy initiative is to advance mine reclamation through the beneficial use of organic residuals for the sustainable establishment of bioenergy crops and other productive land uses. Target organic residuals include: source separated organic compost; papermill biosolids; leaf and yard waste compost; and municipal wastewater biosolids. This presentation discussed the Green Mines green energy initiative with particular reference to potential uses; current participants; scope of the initiative; and progress to date. The presentation also discussed a column study that involved adding filter, filter fabric, silica sand and polyethylene beads to the base of columns. Unoxidized tailings were slurried and pumped into columns and then the oxidized tailings were dried and homogenized. The results of acidic copper/nickel tailings with lime and no lime were also discussed. A summary of findings from the column study was offered. It was found that nutrient management must be considered and organic covers appear to increase metal and arsenic leaching from unlimed tailings. The presentation also made reference to demonstration field plots; biosolids delivery; tilling; monitoring; biomass sampling; and harvesting. The presentation concluded with a discussion of next steps which involve completing construction of the current suite of field plots and implementing full monitoring. figs.

    Aiming at providing a comprehensive assessment of the water-energy nexus, the National Energy-Water System (NEWS) project requires the integration of data to support a modeling framework that links climate, hydrological, power production, transmission, and economical models. Large amounts of Georeferenced data has to be streamed to the components of the inter-disciplinary model to explore future challenges and tradeoffs in the US power production, based on climate scenarios, power plant locations and technologies, available water resources, ecosystem sustainability, and economic demand. We used open source and in-house build software components to build a system that addresses two major data challenges: On-the-fly re-projection, re-gridding, interpolation, extrapolation, nodata patching, merging, temporal and spatial aggregation, of static and time series datasets in virtually any file formats and file structures, and any geographic extent for the models I/O, directly at run time; Comprehensive data management based on metadata cataloguing and discovery in repositories utilizing the MAGIC Table (Manipulation and Geographic Inquiry Control database). This innovative concept allows models to access data on-the-fly by data ID, irrespective of file path, file structure, file format and regardless its GIS specifications. In addition, a web-based information and computational system is being developed to control the I/O of spatially distributed Earth system, climate, and hydrological, power grid, and economical data flow within the NEWS framework. The system allows scenario building, data exploration, visualization, querying, and manipulation any loaded gridded, point, and vector polygon dataset. The system has demonstrated its potential for applications in other fields of Earth science modeling, education, and outreach. Over time, this implementation of the system will provide near real-time assessment of various current and future scenarios of the water-energy nexus.

    The Korean government announced the 'Basic Plan for National Energy towards 2030' last year. The goal of the plan is to achieve energy security, energy efficiency and environmental protection. To achieve green development Korean government plans to increase the portion of nuclear and renewable energy and reduce that of coal and oil energy. According to the plan, Korea will build another 9 units until 2030 and nuclear energy will represent 59% of electricity demands by 2030 which is about 20% higher than last year. Even though environment surrounding the nuclear industry is changing favorably and the government has a plan to increase nuclear energy for green development and optimal energy mix, we have to meet some challenges in the area of safety, waste disposal, public acceptance, and technology development. In this paper, we introduced the history, current status and future prospect of the nuclear industry in Korea, discussed new roles of nuclear energy, and made suggestions how to meet challenges and brace up for the global nuclear renaissance.

    This following project demonstrates an interdisciplinary method of teaching Sustainability, Energy and Green Economics. It is shown that an interdisciplinary approach to introduce students to the foundations of sustainability strongly connects education with real world applications, and highlights the growing influence of sustainable practices on the world at large. The authors will present results from the interdisciplinary course "Sustainability, Energy and Green Economy" taught at the Center of Sustainable Energy, Bronx Community College, City University of New York (CSE-BCC-CUNY) by faculty from Physics, Chemistry, Biology. The course curriculum covers the relationship of humans within their environment, the facts of climate change, an analysis of the current global energy portfolio, the burgeoning renewable energy sector, and connections between consumption and quality of life. The students are exposed to empirical data and asked to evaluate trends to ascertain the future energy and resource demands of a growing global population. The students are lead through an estimation of their own carbon footprint. Emphasis is made on the concept of `Life Cycle Analysis' and how such analyses can be used to create market value and a "green product". The interdisciplinary approach to teach students on how the principles of sustainability are building the green economy and how to build a successful career within today's workforce encourages students to apply the critical lens of sustainability to all aspects of their personal lives, as well as local, regional and global economies. The authors will present data collected by students to formulate and articulate a hypothesis specifically related to the sustainability of societal and economic market trends.

    2014-12-01

    NEWS: 10 years ago, NASA established the NASA Energy and Water-cycle Study (NEWS), whose long-term grand challenge is to document and enable improved, observationally based, predictions of water and energy cycle consequences of Earth system variability and change. The NEWS program builds upon existing NASA-supported basic research in atmospheric physics and dynamics, radiation, climate modeling, and terrestrial hydrology. While these NASA programs fund research activities that address individual aspects of the global energy and water cycles, they are not specifically designed to generate a coordinated result. NEWS developed the first coordinated attempt to describe the complete global energy and water cycle using existing and forthcoming satellite and ground based observations, and laying the foundation for essential NEWS developments in model representations of atmospheric energy and water exchange processes. This comprehensive energy and water data analysis program exploited crucial datasets, some requiring complete re-processing, and new satellite measurements. NAWP: Dramatically changing climates has had an indelible impact on North America's water crisis. To decisively address these challenges, we recommend that NAWP coalesce an interdisciplinary, international and interagency effort to make significant contributions to continental- to decision-scale hydroclimate science and solutions. By entraining, integrating and coordinating the vast array of interdisciplinary observational and prediction resources available, NAWP will significantly advance skill in predicting, assessing and managing variability and changes in North American water resources. We adopt three challenges to organize NAWP efforts. The first deals with developing a scientific basis and tools for mitigating and adapting to changes in the water supply-demand balance. The second challenge is benchmarking; to use incomplete and uncertain observations to assess water storage and quality dynamics, and

    Soft Computing in Green and Renewable Energy Systems provides a practical introduction to the application of soft computing techniques and hybrid intelligent systems for designing, modeling, characterizing, optimizing, forecasting, and performance prediction of green and renewable energy systems. Research is proceeding at jet speed on renewable energy (energy derived from natural resources such as sunlight, wind, tides, rain, geothermal heat, biomass, hydrogen, etc.) as policy makers, researchers, economists, and world agencies have joined forces in finding alternative sustainable energy solutions to current critical environmental, economic, and social issues. The innovative models, environmentally benign processes, data analytics, etc. employed in renewable energy systems are computationally-intensive, non-linear and complex as well as involve a high degree of uncertainty. Soft computing technologies, such as fuzzy sets and systems, neural science and systems, evolutionary algorithms and genetic programming, and machine learning, are ideal in handling the noise, imprecision, and uncertainty in the data, and yet achieve robust, low-cost solutions. As a result, intelligent and soft computing paradigms are finding increasing applications in the study of renewable energy systems. Researchers, practitioners, undergraduate and graduate students engaged in the study of renewable energy systems will find this book very useful. (orig.)

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

    Green buildings uses processes that are environmentally responsible and resource-efficient throughout a building's life-cycle. In these buildings Certain energy conservative and environment friendly steps are considered and implemented from design, construction, operation, maintenance and renovation. In present era no doubt new technologies are constantly constructed and used in creating greener structures, energy efficient buildings. The common objective is to reduce the overall impact of the built environment on human health using available energy efficiently. To increase the efficiency of the System or the building, Onsite generation of renewable energy through solar power, wind power, hydro power, or biomasscan significantly reduce the environmental impact of the building. Power generation is generally the most expensive feature to add to a building. Any how power generation using renewable sources that is Solar system may further enhance energy conservation ideas. Power Factor improvement can also be another source of efficient tool for efficient use of Electrical Energy in green buildings. In developing countries a significant amount of Electrical Energy can be conserved and System efficiency as a whole can be increased by Power Factor correction. The reverse flow of power can be locally engaged instead of creating extra stress and opposition to the existing grid lines.

    This paper considers cost allocation in networks where agents are characterized by stochastic demand and supply of a non-storable good, e.g. green energy. The grid itself creates possibilities of exchanging energy between agents and we propose to allocate common costs in proportion to the economi...... gain of being part of the grid. Our model includes a set of fundamental requirements for the associated trading platform. In particular, it is argued that a suitable mechanism deviates from a traditional market. The approach is illustrated by simulations....

    2016-07-19

    Wave and tidal energy plants are upcoming, potentially green technologies. This study aims at quantifying their various potential environmental impacts. Three tidal stream devices, one tidal range plant and one wave energy harnessing device are analyzed over their entire life cycles, using the ReCiPe 2008 methodology at midpoint level. The impacts of the tidal range plant were on average 1.6 times higher than the ones of hydro-power plants (without considering natural land transformation). A similar ratio was found when comparing the results of the three tidal stream devices to offshore wind power plants (without considering water depletion). The wave energy harnessing device had on average 3.5 times higher impacts than offshore wind power. On the contrary, the considered plants have on average 8 (wave energy) to 20 (tidal stream), or even 115 times (tidal range) lower impact than electricity generated from coal power. Further, testing the sensitivity of the results highlighted the advantage of long lifetimes and small material requirements. Overall, this study supports the potential of wave and tidal energy plants as alternative green technologies. However, potential unknown effects, such as the impact of turbulence or noise on marine ecosystems, should be further explored in future research.

  6. Downstream-based Scheduling for Energy Conservation in Green EPONs

    2012-05-01

    Maximizing the optical network unit’s (ONU) sleep time is an effective approach for achieving maximum energy conservation in green Ethernet passive optical networks (EPONs). While overlapping downstream and upstream ONU transmissions can maximize the ONU sleep time, it jeopardizes the quality of service (QoS) performance of the network, especially for downstream traffic in case the overlapping is based on the upstream time slot. In this paper, we study the downstream traffic performance in green EPONs under the limited service discipline and the upstream-based overlapped time window. Specifically, we first derive the expected mean packet delay, and then present a closed-form expression of the ONU sleep time, setting identical upstream/downstream transmission cycle times based on a maximum downstream traffic delay re-quirement. With the proposed system model, we present a novel downstream bandwidth allocation scheme for energy conservation in green EPONs. Simulation results verify the proposed model and highlight the advantages of our scheme over conventional approaches.

    In practical terms, strategic planning for the nation's economic, social and environmental future increasingly centers on issues relating to fresh water. U.S. energy security is highly dependent on electricity generated by the nation's fleet of thermoelectric power stations, which today contribute 90% to total electricity production. This presentation summarizes the overall structure and recent progress on a study devoted to climate adaptation and the reliability of power sector infrastructure and operations, when viewed through the lens of strategic water issues. The focus is on electric power infrastructure, i.e., the types, spatial distributions and levels of investment in technologies that deliver or could deliver electricity to the U.S. economy. The work is guided by a central hypothesis, that today's portfolio of electric power sector infrastructure is unsustainable in the context of satisfying its water needs under anticipated climate change and rising electricity demands. Insofar as water-mediated feedbacks reverberate throughout the national economy, we include macro-economic perspectives as well. The work is organized around the technical development of the NEWS framework which is then used to evaluate, in the context of anticipated climate, economic change and regulatory context: the performance of the nation's electricity sector, the feasibility of alternative pathways to improve climate adaptation, and impacts of energy technology. Scenarios are co-designed with a stakeholder community, and investment tradeoffs are considered with respect to the productivity of the economy, water availability and aquatic ecosystem condition.

However, “green” also means fresh, new and healthy.For Russia, and for Siberia in particular, “green” architecture does sound new and fresh. Forced by the anxious reality, we are addressing this topic intentionally. The ecological crisis, growing energy prices, water, air and food deficits… Alexander Rappaport, our regular author, writes: “ It has been tolerable until a certain time, but under transition to the global civilization, as the nature is destroyed, and swellings of megapolises expand incredibly fast, the size and the significance of all these problems may grow a hundredfold”.However, for this very severe Siberian reality the newness of “green” architecture may turn out to be well-forgotten old. A traditional Siberian house used to be built on principles of saving and environmental friendliness– one could not survive in Siberia otherwise.Probably, in our turbulent times, it is high time to fasten “green belts”. But we should keep from enthusiastic sticking of popular green labels or repainting of signboards into green color. We should avoid being drowned in paper formalities under “green” slogans. And we should prevent the Earth from turning into the planet “Kin-dza-dza”.

    The manner in which the world has conducted itself in exploiting energy resources so far particularly in the post industrial revolution period, is now looming as one of the greatest challenges to the sustainability of development or even sustainability of life. Global climate change is no more a perceived threat, it is now a reality and we are not in a position to engage ourselves to debate on the issue. It is in fact a little late in taking the right corrective action if we have any concern for our future generations. The efforts of the scientists and engineers are to gradually replace the energy from burning of carbonaceous material to clean and intense source of energy i.e. nuclear fission and fusion

    2014-08-01

    Full Text Available Across the world governments make decisions on climate change and environmental pollution saying that is the most important goal for the future of their states. Accumulation of environmental problems was done in decades of irrational and unplanned exploitation. Industrialization itself is not a bad thing for humanity [9], but how this is achieved can be detrimental to the future of global society. Environment reverses the conditions created for man in so many thousands of years: thus, economic life is becoming increasingly difficult through its activities. Plants and animals disappear land turns into deserts, people get sick. The present paper attempts to find solutions to a global, national and regional situation, referring to those types of infrastructure viable to produce clean energy in Romania. This paper argues the need of green energy and propose alternative and environmentally friendly cleaner solutions.

  18. The green bubble: waste into wealth: the new energy revolution

    International Nuclear Information System (INIS)

    Belle, R.

    2007-01-01

    In this exhaustive (and exhausting) look at the future of energy, Bell, a professor of management and chairman of the economics department at Brooklyn College, CUNY, maps a complicated future for investors and laymen with clear-eyed examination of failed U.S. environmental policy and worldwide efforts to break away from oil. Under discussion are a wide range of topics: the stampede away from oil; wind energy and turbines; photovoltaic opportunities; what car-makers are saying and what they're actually doing (including a careful look at the popular Toyota Prius); the extremely lengthy timetables for new energy-saving technologies to get off the ground; and the processes, research and expectations tied up in them all. Drawing an analogy to the dot-com debacle, Bell predicts investment in the hot properties of energy tech will lead to a bubble effect, eventually draining the financial resources of investors who linger too long. Frequently fascinating anecdotes-as in the story of Sweden's green welfare state and bicycles of Lyon-buoy what otherwise can read like a university course. Bell's latest (following 2003's The Stock Market Sting) is an educated, opinionated tour through the future of energy economics that should shore up the will and wisdom of investors, as well as open the eyes of average Americans.

  19. Tools to fiht ticks: A never-ending story? News from the front of green acaricides and photosensitizers

    Directory of Open Access Journals (Sweden)

    Giovanni Benelli

    2016-08-01

    Full Text Available Nowadays, parasitology is facing a number of crucial challenges, including the urgent request of effective control tools against arthropod vectors of medical and veterinary importance. Ticks transmit at least the same amount or even more pathogen species than any other group of blood-feeding arthropods worldwide affecting humans and animals. Besides the development of vaccines against viruses vectored by ticks, integrated pest management practices aimed at reducing tick interactions with livestock, emerging pheromone-based control tools, and few biological control agents have been also proposed. The extensive employ of acaricides and tick repellents still remains the two most effective and ready-to-use strategies. However, the use of synthetic acaricides is limited by the development of resistance in several tick species as well as by heavy environmental concerns. In this scenario, the exploitation of botanicals as cheap and effective sources of tick repellents may represent a valid alternative, and the preservation of ethnobotanical information on the repellent and acaricidal potential of plants is crucial. On the other hand, novel photodynamic acaricides have been recently described, with a toxicity against ticks which far exceed some of the acaricides currently marketed (e.g. tetramethrin. In this brief review, I provide a focus on some hot news in tick control, with special reference to tick repellents of botanical origin and new photodynamic fluorescent acaricides. To my mind, knowledge on both the mentioned research issues may help researchers to build valuable roadmaps to boost tick control programs worldwide.

    The demand of power is increasing day by day due to the increase of world population as well as the industrialization and modernization. Depletion of the world's fossil fuel reserves and the adverse effects of their uses on the environment insist the researchers to find out some means of efficient and cost effective alternative energy sources from small to large scales. In a gymnasium the human metabolism power is used to drive the physical exercise devices. However there are a number of exercise device which can have the potential to generate electricity during physical exercise. By converting the available mechanical energy from these exercise devices into kinetic energy, electric power can be produced. In this work, energy was harvested from the most commonly used physical exercise devices used in the gymnasium - paddling and chin up. The paddle pulley and the chin up pulley were connected to the couple pulley which in turn coupled to an alternator by a V-belt to produce electrical energy and a rechargeable battery was used to store electrical energy. The power generation from the device depends upon the speed at which the alternator runs and the age limit. The electrical energy output was observed 83.6 watt at 1300 rpm and 62.5 watt at1150 rpm alternator speed for the paddling and chin up respectively recorded for an average adult. The device was designed for a constant 49N load on the alternator for both paddling and chin up operation. By running each of these devices for about 12 hours in a day, any gymnasium can avoid burning of almost 23.67 kg and 31.6 kg of diesel fuel per year for chin up and paddling respectively. Also it can cut off the CO2 emission to the environment which reveals itself a standalone green micro gym.

    Tsang, S.W.; Jim, C.Y.

    2011-01-01

    The thermal and energy efficiency of tropical green roofs is assessed by a theoretical model to clarify the contribution of underlying factors. The suitability of 1400 high-rise public housing blocks in Hong Kong for rooftop greening was assessed by remote sensing images. Weather and microclimatic-soil monitoring data of an experimental green roof provided the basis for computations. Roof greening prevented a huge amount of solar energy at 43.9 TJ in one summer from penetrating the buildings to bring significant energy saving. Thermal performance of humid-tropical green roofs, with greater latent heat dissipation, is twice more effective than the temperate ones. The energy balance model shows that solar energy absorption by bare and green roofs depends on shortwave rather than longwave radiation. Heat flux into a building indicates a one-day time lag after a sunshine day. With restricted evapotranspiration, bare roofs have more sensible heat and heat storage than green roofs. The bare roof albedo of 0.15, comparing with 0.30 of green roof, renders 75% higher heat storage. Small increase in convection coefficient from 12 to 16 could amplify 24% and 45% of latent heat dissipation respectively for bare and green roofs. Doubling the soil water availability could halve the heat storage of green roofs. -- Highlights: → We developed a theoretical model to calculate the thermal performance of tropical green roofs. → Bare roofs have more sensible heat and heat storage than green roofs. → Latent heat dissipation of tropical green roofs is twice that of temperate counterparts. → Heat flux through the roof into a building demonstrates a one-day time lag after a long sunshine day. → Green roofs can block 43.9 TJ of solar energy penetration into public housing buildings in one summer.

    Green residence development has been one of the important strategies for promoting sustainable urban development. Governments throughout the world have been encouraging property developers to deliver green properties. In line with this development, governments have been implementing various assessment programs to certify green residential buildings with the aim of contributing to sustainable urban development. With reference to the Chinese construction practice, this paper examines the effectiveness of the green residence assessment scheme toward its defined aim through investigating the contents and procedures of the green residence assessment scheme by referring to the practices of Chongqing city in western China. Based on the results of five case studies and five semi-structured interviews, this study reveals the significant contribution from implementing the green residence assessment scheme particularly to energy saving in residential buildings. Further, the green residence assessment scheme promotes the application of green building materials and green construction technologies in the entire process of delivering and operating residential buildings. The findings provide valuable references for further investigating alternative methods to achieve better energy saving in developing residential buildings. - Highlights: ► Energy saving in residence development is important for sustainable urban development. ► Green residence assessment scheme contributes significantly to energy saving in residences. ► Green residence assessment promotes application of environmentally friendly building materials and technologies

    India's energy consumption is growing rapidly for last three decades. The per capita energy consumption is increasing at an average rate of 3.6% per annum for last two decades. Also, the population of India is increasing at a rate of 1.5 % per annum. This makes it clear that conventional fossil fuel based system will not be able to fulfill the demand of energy in future period. To achieve and maintain desired economic and industrial growth rates, reliable supply of required amount of energy at reasonable cost is a necessity. Encouraging use of non-conventional energy sources on a commercial basis can be a major step towards self sufficiency in energy sector. India has a very large potential for developing and utilizing green energy sources such as wind energy, solar energy, geothermal energy, etc. These sources can satisfy India's growing energy demand to a large extent. Fuel cells can serve as a major source of energy with their clean energy production, higher efficiencies, modularity and ability to give reliable supply of energy at constant rates. Thus, fuel cells serve for diversification and localization of energy sources, which is important for energy security. This paper reviews current energy status of India and presents fuel cell as a prospective candidate for achieving energy security. (author)

    Renewable energy received a boost in Ontario, Canada with the Green Energy and Green Economy Act (GEGEA), ushering in a new Feed-in-Tariff (FIT) program modelled on programs from Germany, Spain, Denmark and other jurisdictions. Information about lessons learned elsewhere has clearly benefited the Ontario experience. Part of the Ontario program included streamlining the impact assessment process to facilitate the swift development of provincial renewable energy capacities. In this context, the GEGEA has been remarkably successful, generating renewable energy sector capacities, resources, projects and their spin-off benefits in Ontario, along with more sustainable electricity system. Environmentalists along with industry continue to laud the benefits of renewable energy and the GEGEA, and with good reason. Renewable energy generation in Ontario has grown from to 2 per cent in 2012 and is expected to reach 10 per cent in 2013. (orig.)

  13. Words vs. deeds: Americans' energy concerns and implementation of green energy policies

    Science.gov (United States)

    Brinker, Garrett C.

    As the effects of climate change become increasingly clear, nations, international organizations, and corporations are working together to help mitigate these negative effects before they become irreversible. The United States, as the world's largest emitter per capita, has a responsibility to take quick and decisive action to decrease carbon emissions. And while an overwhelming majority of Americans believe that green energy policies are the right step forward, few have taken meaningful steps to actually implement these policies. Green and energy efficient technologies such as hybrid and electric cars, smart meters, and solar panels---technologies that would reduce our carbon footprint---are currently purchased or used by very few households. There is a clear gap between our words and deeds. Using the University of Texas at Austin Energy Poll dataset, this paper examines this gap and analyzes how income may influence what people say, versus how they act, seeking to better understand how income influences peoples' energy behaviors. Previous literature suggests that income has proven to be an inconsistent measure of concern for energy use. Through two OLS models, this paper finds that income is negatively correlated with Americans' concern for energy usage, while finding that there is a positive correlation between income and Americans' implementation of energy efficient technologies. Further, there is a nonlinear relationship between income groups and how Americans both think about their energy usage and actually implement more energy efficient measures.

    2010-01-01

    As the mandate for minimum renewable sources renders Tradable Green Certificates (TGCs) an essential input for power generation, it may induce mergers between power companies of conventional and renewable sources. Such mergers enable the integrated firms to extend market power from the TGC market to the physical energy market. We find that the price of TGCs is indeed higher in the integrated market than the disintegrated market, indicating the presence of market power leveraging. However, despite higher TGC price, the total supply of electricity is greater under integration than disintegration, reflecting efficiency gains from vertical integration, which eliminates double marginalization. The thrust of this paper is that market changes induced by environmental policies will in turn affect environmental and economic regulations. For example, increased supply resulting from integration induced by the renewable source mandate may reduce the effectiveness of programs that promote energy saving behavior, but at the same time creates room for raising the minimum of renewable sources without unduly depressing production and consumption.

    In conventional Green close-quote s function methods the vertex function Γ is generally energy dependent. However, a model-space Green close-quote s function method where the vertex function is manifestly energy independent can be formulated using energy-independent effective interaction theories based on folded diagrams and/or similarity transformations. This is discussed in general and then illustrated for a 1p1h model-space Green close-quote s function applied to a solvable Lipkin many-fermion model. The poles of the conventional Green close-quote s function are obtained by solving a self-consistent Dyson equation and model space calculations may lead to unphysical poles. For the energy-independent model-space Green close-quote s function only the physical poles of the model problem are reproduced and are in satisfactory agreement with the exact excitation energies. copyright 1996 The American Physical Society

  17. A cautionary approach in transitioning to 'green' energy technologies and practices is required.

    Science.gov (United States)

    Matatiele, Puleng; Gulumian, Mary

    2016-06-01

    Renewable energy technologies (wind turbines, solar cells, biofuels, etc.) are often referred to as 'clean' or 'green' energy sources, while jobs linked to the field of environmental protection and energy efficiency are referred to as 'green' jobs. The energy efficiency of clean technologies, which is likely to reduce and/or eliminate reliance on fossil fuels, is acknowledged. However, the potential contribution of green technologies and associated practices to ill health and environmental pollution resulting from consumption of energy and raw materials, generation of waste, and the negative impacts related to some life cycle phases of these technologies are discussed. Similarly, a point is made that the green jobs theme is mistakenly oversold because the employment opportunities generated by transitioning to green technologies are not necessarily safe and healthy jobs. Emphasis is put on identifying the hazards associated with these green designs, assessing the risks to the environment and worker health and safety, and either eliminating the hazards or minimizing the risks as essential elements to the design, construction, operation, and maintenance of green technologies. The perception that it is not always economically possible to consider all risk factors associated with renewable energy technologies at the beginning without hampering their implementation, especially in the poor developing countries, is dismissed. Instead, poor countries are encouraged to start implementing environmentally sound practices while transitioning to green technologies in line with their technological development and overall economic growth.

    The focus of this talk is on climate adaptation and the reliability of power supply infrastructure when viewed through the lens of strategic water issues. Power supply is critically dependent upon water resources, particularly to cool thermoelectric plants, making the sector particularly sensitive to any shifts in the geography or seasonality of water supply. We report on results from an NSF-Funded Water Sustainability and Climate effort aimed at uncovering key energy and economic system vulnerabilities. We have developed the National Energy-Water System assessment framework (NEWS) to systematically evaluate: a) the performance of the nation's electricity sector under multiple climate scenarios; b) the feasibility of alternative pathways to improve climate adaptation; and, c) the impacts of energy technology and investment tradeoffs on the economic productivity, water availability and aquatic ecosystem condition. Our project combines core engineering and geophysical models (ReEDS [Regional Energy Deployment System], TP2M [Thermoelectric Power and Thermal Pollution], and WBM [Water Balance]) through unique digital "handshake" protocols that operate across different institutions and modeling platforms. Combined system outputs are fed into a regional-to-national scale economic input/output model to evaluate economic consequences of climate constraints, technology choices, and environmental regulation. The impact assessments in NEWS are carried out through a series of climate/energy policy scenario studies to 2050. We find that despite significant climate-water impacts on individual plants, the current US power supply infrastructure shows potential for adaptation to future climates by capitalizing on the size of regional power systems, grid configuration and improvements in thermal efficiencies. However, the magnitude and implications of climate-water impacts vary depending on the configuration of the future power sector. To evaluate future power supply performance, we

    Linhart, F.; Scartezzini, J.-L.

    2009-10-15

    The objective of the Green Lighting project was to develop a High Performance Integrated Lighting System, based on advanced technologies for day- and electric lighting, achieving a Lighting Power Density (LPD) that does not exceed 3 W/m{sup 2}. The project has revealed that Anidolic Daylighting Systems (ADS) are an ideal basis for High Performance Integrated Lighting Systems. Not only are they able to provide adequate illumination (i.e. sufficiently high illuminance) in office rooms during large fractions of normal office hours, under various sky conditions and over the entire year, but they are also highly appreciated by office occupants at the condition that glare control mechanisms are available. Complementary electric lighting is, however, still necessary to back up the ADS at times when there is insufficient daylight flux available. It was shown during this project, that the most interesting trade-offs between energy-efficiency and visual comfort are obtained by using a combination of ceiling-mounted directly emitting luminaires with very high optical efficiencies for ambient lighting and portable desk lamps for temporary task lighting. The most appropriate lamps for the ceiling-mounted luminaires are currently highly efficient fluorescent tubes, but white LED tubes can be considered a realistic option for the future. The most suitable light sources for desk lamps for temporary task lighting are Compact Fluorescent Lamps (CFLs) and white LED light bulbs. Based on the above-mentioned technologies, a High Performance Integrated Lighting System with a very low LPD has been developed over the last three years. The system has been set up in an office room of the LESO solar experimental building located on the EPFL campus; it has been tested intensively during a Post-Occupancy Evaluation (POE) study involving twenty human subjects. This study has revealed that the subjects' performance and subjective visual comfort was improved by the new system, compared to

    Frame fragmentation techniques aim to achieve higher throughput by reducing retransmissions. Using experiments on a WSN testbed, we show that frame fragmentation also helps to reduce energy consumption. In this paper we propose Green-Frag, a new energy-efficient protocol based on efficient frame fragmentation technique. Green-Frag allows sensor nodes to transmit data with optimal transmit power and frame structure based on environmental conditions. Green-Frag takes into consideration the channel conditions, interference patterns and level, as well as the distance between sender and receiver. The paper discusses various design and implementation considerations for Green-Frag. Using experimental evaluation on a sensor mote testbed, we show that Green-Frag achieves the least energy consumption by choosing the best transmit power according to the channel conditions.

    In a ''green roof,'' a layer of vegetation (e.g., a roof garden) covers the surface of a roof to provide shade, cooler indoor and outdoor temperatures, and effective storm-water management to reduce runoff. The main components are waterproofing, soil, and plants. There are two basic kinds: intensive and extensive. An intensive green roof often features large shrubs and trees, and it can be expensive to install and maintain. An extensive green roof features shallow soil and low-growing, horizontally spreading plants that can thrive in the alpine conditions of many rooftops. These plants do not require a lot of water or soil, and they can tolerate a significant amount of exposure to the sun and wind.

    Full Text Available Green roofs may be considered a passive energy saving technology that also offer benefits like environmental friendliness and enhancement of aesthetic and architectural qualities of buildings. This paper examines the energy and economic viability of the green roof technology in the hot humid climate of Saudi Arabia by considering a modern four bedroom residential building in the city of Dhahran as a case study. The base case and green roof modelling of the selected building has been developed with the help of DesignBuilder software. The base case model has been validated with the help of 3-month measured data about the energy consumption without a green roof installed. The result shows that the energy consumption for the base case is 169 kWh/m2 while the energy consumption due to the application of a green roof on the entire roof surface is 110 kWh/m2. For the three investigated green roof options, energy saving is found to be in the range of 24% to 35%. The economic evaluation based on the net present value (NPV approach for 40 years with consideration to other environmental advantages indicates that the benefits of the green roof technology are realized towards the end of the life cycle of the building.

    2016-01-01

    Full Text Available Forward from the sustainability agenda of Brundtland in 1987 and the increasing demand for energy efficient buildings, the building industry has taken steps in meeting the challenge of reducing its environmental impact. Initiatives such as ‘green’ or ‘sustainable’ design have been at the forefront of architecture, while green assessment tools have been used to predict the energy performance of building during its operational phase. However, there is still a significant hap between predicted or simulated energy measurements compared to actual operational energy consumption, or is more commonly referred as the ‘performance gap’. This paper tries to bridge this gap by comparing measured operational energy consumption of a Green Building Index (GBI certified office building in Kuala Lumpur, with its predicted energy rating qualification.

    2011-11-10

    Over 2 trillion Euros is spent on public contracts on a yearly basis in the EU, translating to 19 percent of its GDP. ICLEI has been working with the European Commission to produce guidance on green public procurement (GPP) which will help public authorities to reduce their environmental impact, while complying with the procurement rules. The result is the new edition of the Buying Green! handbook. The handbook identifies strategies for GPP, and explains in detail how these can be implemented at each stage of the procurement process. It is intended for public sector procurers but is also a useful reference for policy makers and businesses who are either implementing their own green purchasing or responding to tenders. In addition to explaining how GPP can be implemented under the EU procurement rules, the handbook includes examples of green contracts from across the EU-27. The resource has been fully updated from the previous 2004 edition and includes expanded sections on life-cycle costing (LCC) and the construction, timber, electricity and food and drink sectors.

  16. RUSTEC: Greening Europe's energy supply by developing Russia's renewable energy potential

    International Nuclear Information System (INIS)

    Boute, Anatole; Willems, Patrick

    2012-01-01

    The North-West of Russia is characterized by a large renewable energy resource base in geographic proximity to the EU. At the same time, EU Member States are bound by mandatory renewable energy targets which could prove to be costly to achieve in the current budgetary context and which often face strong local opposition. Directive 2009/28/EC on Renewable Energy makes it possible for Member States to achieve their targets by importing electricity produced from renewable energy sources from non-EU countries. So far, most attention has been on the Mediterranean Solar Plan or Desertec. An EU–Russia Renewable Energy Plan or RUSTEC – being based on onshore wind/biomass/hydro energy and on-land interconnection, rather than solar power and subsea lines – could present a cost-efficient and short-term complement to Desertec. This article examines the political, geopolitical, economic, social and legal challenges and opportunities of exporting “green” energy from Russia to the EU. It argues that EU–Russian cooperation in the renewable energy field would present a win-win situation: Member States could achieve their targets on the basis of Russia's renewable energy potential, while Russia could begin to develop a national renewable energy industry without risking potential price increases for domestic consumers—a concern of great political sensitivity in Russia. - Highlights: ► Russia has a huge renewable energy potential in geographic proximity to the EU. ► This potential could help the EU decarbonize its electricity supply at least cost.► EU–Russia green energy export is a win-win situation but lacks political attention.► RUSTEC could be a short-term and cost-efficient complement to Desertec. ► RUSTEC would diversify EU energy imports/Russian exports and stimulate innovation.

    International Nuclear Information System (INIS)

    2015-01-01

    Electric power grid operators are facing new challenges, including rising energy consumption and emissions, the need to integrate renewable energy sources, and the emergence of electric vehicles. There is an urgent need to make grids safer, more efficient, environmentally 'greener', and more flexible. In a word: smarter. Schneider Electric has teamed with 4 partners (GEG, GDF Suez, ERDF and GINP) and 6 others on the GreenLys project, the first full-scale smart grid demonstration project in France. Partially financed by the French Environment and Energy Management Agency (ADEME), the consortium has developed an experimental technology platform being tested in the cities of Lyon and Grenoble, ultimately involving 1,000 residential customers and 40 commercial building sites. The goal is to standardize and showcase a functional smart grid by 2015, setting the stage for widespread deployment. The GreenLys project is testing innovative solutions from energy generation to end use. At the grid level this includes new analysis tools, next generation substation automation equipment, and communication with smart meters at consumer locations. The grid will be self-healing, quickly reconfiguring itself to maintain the supply of electricity. It will also incorporate decentralised energy generation based on renewables or natural gas, as well as the potential to use stored energy in electric vehicles. At the end-consumer level, a variety of new technologies are applied to engage businesses and homeowners. The cloud-based Demand-Side Operation platform will enable participation in programs like demand response that offer financial incentives for adjusting energy consumption when required. Such programs will help energy users optimize their energy bill and encourage energy-efficient practices. Offering their energy flexibility to the smart grid will also help alleviate peak demand and compensate for the intermittency of large-scale renewable energy production. For commercial

  18. The security of energy supply. The European Commission's Green Paper stimulates debate

    International Nuclear Information System (INIS)

    2000-01-01

    The growing dependence of the European Union (EU) on external supplies of energy is the central focus of a ''Green Paper'' issued in late November 2000 by the Commission of the European Communities in Brussels. Entitled ''Towards a European Strategy for the Security of Energy Supply'', the Green Paper is intended to stimulate debate on the EU's energy policies and strategies. European member States are ''interdependent'', the Green Paper states, ''both because of climate change issues and the creation of the internal energy market. Any energy policy decision taken by a Member State will inevitably have repercussions on the functioning of the market in other Member States. Energy policy has assumed a new, Community dimension.'' Three main points emerge from the Green Paper: The EU will become increasingly dependent on external energy sources; its enlargement will not change this situation. Based on current forecasts, energy dependence will reach 70% by the year 2030. - The EU has very limited scope to influence energy supply conditions; it is essentially on the demand side that the EU can intervene, mainly by promoting energy saving in buildings and the transport sector. - The EU presently is not in a position to respond to the challenge of climate change and to meet its commitments, notably under the Kyoto Protocol. Featured here is the Executive Summary of the Green Paper

    2014-07-01

    The rising energy costs and carbon footprint of operating mobile telecommunication sites in the emerging world have increased research interests in green technology. The intermittent nature of most green energy sources creates the problem of designing the optimum configuration for a given location. This study presents the design analysis and control strategy for a cost effective and reliable operation of the hybrid green energy system (HGES) for GSM base transceiver station (BTS) sites in isolated regions. The design constrains the generation and distribution of power to reliably satisfy the energy demand while ensuring safe operation of the system. The overall process control applies the genetic algorithm-based technique for optimal techno-economic sizing of system's components. The process simulation utilized meteorological data for 3 locations (Abuja, Benin City and Sokoto) with varying climatic conditions in Nigeria. Simulation results presented for green GSM BTS sites are discussed and compared with existing approaches.

    2011-07-01

    Traditional village houses now use renewable materials and energy sources and this paper presents the intrinsic harmony of these buildings' greening and their sustainability. The paper covers building technical systems, sustainable energy supply, and the importance of renewable raw materials (RMS) for sustainable development. This study investigated the role of building dynamic behavior and optimized energy efficiency in reducing thermal loads significantly. A preliminary design for sustainable energy efficient settlements with net zero energy buildings is proposed and a comprehensive multidisciplinary engineering study was done which identified the technical feasibility of sustainable village energy and water supplies using solar or wind technologies. Overall, through analysis of sustainability definitions and possible ways to achieve sustainability, the study demonstrated that this can only be brought about by interdisciplinary interaction and finding the right balance between materiality and spirituality, science and art, and between technological development and concern for cultural and other human values.

  6. Dynamic Simulation of the Green Roofs Impact on Building Energy Performance, Case Study of Antananarivo, Madagascar

    Directory of Open Access Journals (Sweden)

    Hery Tiana Rakotondramiarana

    2015-05-01

    Full Text Available Green roofs improve building energy performance and constitute an alternative to sustainable buildings. A green roof model is dynamically coupled with a building thermal model to assess its energy performance that takes into account the indoor air temperature dynamic changes. Under the climate conditions in Antananarivo, we compared green and conventional roofs. The present study shows that green roofs protect the roof structure under extreme temperature and large temperature fluctuations. For the case of Antananarivo, the amplitude of the temperature fluctuations at the top face of the support is reduced by 28 °C when using green roof. The impact of the green roof on indoor air temperature and energy demand is investigated. The vegetation decreases the maximum indoor air temperature and improves the building thermal comfort during summer days. It has no effect on the minimum indoor air temperature, but additional soil thickness can increase it. In addition, a global sensitivity analysis, which is carried out on the proposed model without considering any specific weather data, allows us to identify the most influential parameters on the energy demand. It has been found that green roofs have almost insignificant thermal impact in insulated buildings; however, their potential prevails over the building envelope and weather characteristics in the case of non-insulated building.

    2011-12-01

    An experimental evaluation of thermal and energy performance of temperate green roofs was carried out by thermal and meteorological observation and energy budget modeling using a setup of green roof in Beijing urban area. From both the yearly and daily temperature trends, the green roof could effectively damp down the undulation of roof surface temperature comparing with the conventional one. As an insulating screen, the green roof abated the amplitude of temperature by 9.0 in winter and 9.1 °C in summer, respectively. Under different cloud conditions, the green roof in summer time resulted in decreases in sensible heat and heat flux by 125.3W m-2 and 32.0 W m-2, respectively, on daily average comparing with the conventional one. Based on the energy budget analyses, under an assumptive scenario of 50% roof-greening in Beijing, a total of 34.1 PJ of sensible heat and 8.7 PJ of heat flux would be decreased for a summer period of 90 days. This study demonstrated that green roof, serving as an insulating screen to building top in comparison with the conventional roof, proved thermal improving effect in building scale and high energy saving potential for urban development.

  8. Assessment of energy credits for the enhancement of the Egyptian Green Pyramid Rating System

    2015-01-01

    Energy is one of the most important categories in the Green Building Rating Systems all over the world. Green Building is a building that meets the energy requirements of the present with low energy consumption and investment costs without infringing on the rights of forthcoming generations to find their own needs. Despite having more than a qualified rating system, it is clear that each system has different priorities and needs on the other. Accordingly, this paper proposes a methodology using the Analytic Hierarchy Process (AHP) for assessment of the energy credits through studying and comparing four of the common global rating systems, the British Building Research Establishment Environmental Assessment Method (BREEAM), the American Leadership in Energy and Environmental Design (LEED), the Australian Green Stars (GS), and the PEARL assessment system of the United Arab Emirates, in order to contribute to the enhancement of the Egyptian Green Pyramid Rating System (GPRS). The results show the mandatory and optional energy credits that should be considered with their proposed weights according to the present and future needs of green Egypt. The results are compared to data gathered through desk studies and results extracted from recent questionnaires. - Highlights: • The Egyptian rating system is underway but not on track. • The main objective is the enhancement of the Egyptian rating system. • We propose a methodology for assessment of the energy credits. • The results show the optional energy credits with their optimal weights. • The results show the mandatory energy credits that should be considered.

    The liberalisation of energy markets has increased the need to enlarge the information base of fuel chains, to evaluate the environmental quality of energy products transparently and to communicate results in a credible way. The preparedness of energy purchasers, producers and sellers to support energy choices of their customers and to meet the information requirements of various stake holders can be strengthened. The environmental impacts related to energy products are turning into a significant dimension of competitiveness. Possibilities to promote market-driven environmental protection mechanisms and to construct incentives, which cover the whole energy production system exist and can be supported. Knowledge of environmental impacts of various energy products can be increased by means of several supplementary instruments like eco-profiles, environmental labels and life cycle assessments of products. Life cycle assessment forms a systematic basis of information, which supports the environmental communications directed to various stake holders. In this study selected public LCA-studies concerning energy production have been compared, criteria of green energy have been charted and their outlook has been assessed. In addition the development of an LCA- based relative environmental performance indicator system, which supports various transparent comparisons, has been outlined. The mapping of methodological differences of published LCA-studies regarding various energy alternatives proves, that there is differences e.g. in allocation principles, system boundaries, and age of source information and in many other details. These discrepancies should be known, because they also affect the results. That is why the use of available LCA studies as a basis for comparative assertions may be problematic. The renewability of an energy source is a threshold requirement in eco-energy criteria formulated and introduced by Finnish, Swedish and Norwegian nature conservation

    2015-01-01

    Against a background of growing international and national carbon reduction legislation, the UK government introduced the “Green Deal” to deliver a significant increase in housing energy efficiency and reduction in carbon emissions. This paper reflects on one English local authority's experience delivering a programme intended to foster local interest in the Green Deal. Drawing on social surveys and pre and post Green Deal intervention interviews with five demonstrator homes (households that applied to receive a Green Deal package fully funded by the scheme, providing a test bed for the Green Deal recruitment and installation process), this paper shows that awareness and understanding of the Green Deal scheme is low. There is opposition to the cost of finance offered but a strong interest in improving household warmth and for funding improvements through payments added to the electricity bill. Demonstrator home residents perceived Green Deals had improved the warmth and quality of their home, but saving money was the primary motivator for their involvement, not increasing warmth. Whilst Green Deal has not delivered the level of success that was hoped, much can be learned from the scheme to improve future energy efficiency schemes that will be necessary to deliver emission reduction commitments. -- Highlights: •Resident awareness and understanding of the Green Deal is low. •Green Deal assessment costs and loan interest rates are biggest barriers to uptake. •Funding energy improvements via a charge on electricity bill welcomed by residents. •Saving money rather than increasing warmth main motivator for scheme involvement. •Insights from this work should be used to inform future emission reduction schemes

    One of the main functions of the public communication of science is to enable ordinary people to appropriate the necessary knowledge to understand the risks and benefits of scientific and technological developments that are part of everyday life. This task is particularly important in cases of important events that move public opinion and call into question the appropriateness of its use. In these cases it is desirable that the journalistic use teaching tools for communicating important aspects of the facts, since they are usually embedded or hidden in the large volume of information provided from the media. This is particularly important in the case of television, which by its characteristics of speed and brevity leaves little time to understand what happened finishing. This paper shows the production made in a television news of Cordoba, including a didactic exhibition on the conditions that occurred during the accident at Japanese nuclear plants after the earthquake and tsunami catastrophe that hit the northeast of the island in March 2011. To carry the note took into account the disparate fields of knowledge existing in the audience, the complexity of disciplinary knowledge to be transmitted and the need to organize content based on the recipients. Used in their making everyday items that exist in any home kitchen in order to introduce the audience to developments and major technical problems affecting nuclear facilities, by explaining the basics of physics involved in accidental situation.

    We study the incidence of carbon-reduction and green-energy promotion policies in an open fossil-fuel importing general equilibrium economy. The focus is on mixed price-based or quantity-based policies. Instruments directed toward promoting green energy are shown to reduce also carbon emissions and vice versa. Their direct effects are stronger than their side effects, the more so, the greater is the elasticity of substitution in consumption between energy and the consumption good. We calculate the effects of variations in individual policy parameters, especially on energy prices and welfare costs, and determine the impact of exogenous fossil-fuel price shocks on the economy.

    An improved GFP gene (mGFP4) was introduced into mature embryo cells of wheat cultivars Wan 9210 and Wanmai 32 via low energy ion beam-mediated delivery technique. Resistant calli were selected on medium containing paromomycin (100-140 mg/L). Five green plants were regenerated from resistant calli of Wan 9210 derived from 387 implated mature embryos. 32 green plants were obtained from 776 irradiated mature embryos in Wanmai 32. No green plant was regenerated from calli of 200 non-transformed embryos. PCR assays of 37 green plants showed that they all obtained the expected size of amplified DNA fragment (600 bp). Southern blot of 4 well-developed green plants confirmed stable integration of GFP gene into wheat genome. The average transformation frequencies of Wan 9210 and Wanmai 32 were 1.3% and 4.1%, respectively, according to the results of PCR assays

    Jurisich, John M.

    The purpose of this quantitative ex post facto research study was to explore the relationship between green initiative expense disclosures and stock prices of 46 NASDAQ listed Clean Edge Green Energy global companies from 2007 to 2010. The independent variables were sales and marketing, environmental, customer and supplier, community, and corporate governance practices that were correlated with the dependent variable in the study of stock prices. Expense disclosures were examined in an effort to measure the impact of green initiative programs and to expose the interrelationships between green initiative expense disclosures and fluctuations of stock prices. The data for the research was secondary data from existing annual reports. A statistically significant relationship was revealed between environmental practices and changes in stock prices. The study results also provided substantial evidence for leadership and managerial decision making to reduce or increase green initiative practices to maximize shareholder wealth of their respective organizations.

    Full Text Available After 1950, began to appear nuclear fission plants. The fission energy was a necessary evil. In this mode it stretched the oil life, avoiding an energy crisis. Even so, the energy obtained from oil represents about 60% of all energy used. At this rate of use of oil, it will be consumed in about 60 years. Today, the production of energy obtained by nuclear fusion is not yet perfect prepared. But time passes quickly. We must rush to implement of the additional sources of energy already known, but and find new energy sources. Green energy in 2010-2015 managed a spectacular growth worldwide of about 5%. The most difficult obstacle met in worldwide was the inconstant green energy produced.

  5. The green paper 'towards a European strategy for the security of energy supply'

    International Nuclear Information System (INIS)

    Laponche, B.; Tillerson, K.

    2001-01-01

    The Green Paper, 'Towards a European Strategy for the Security of Energy Supply' was adopted by the European Commission on the 20. of November, 2000 (COM(2000)769 final). At this occasion, the Commission launched a public debate on this strategic document. On the 21. of June 2001, a Public Hearing on Security of energy supply in Europe, on the basis of the Green Paper, was organised by the Committee on Industry, External Trade, Research and Energy of the European Parliament. Bernard Laponche was among the six experts participating to the Hearing and presented the following paper, prepared with Kenya Tillerson. This presentation is organised in three chapters: I - Comments on the Green Paper; II - Energy efficiency potentials; III - Conclusions and Recommendations. Chapter I shows that under the heading of the security of supply, the Green paper elaborates and proposes a global energy strategy taking into account environmental and internal market issues and constraints. This leads to recommendations for a common energy policy for Europe based, as first priority, on a demand policy, i.e. energy efficiency on the demand side. If the necessity of such a policy is clearly stated, the Green paper remains weak on the quantitative objectives, due to the lack of contrasted energy forecast scenarios, as well as on the means of a vigorous energy efficiency policy at European Level. The issue of energy efficiency potentials at European Union level is examined in Chapter II, in the light of the poor information which can be extracted from the energy scenarios presented by the European Commission in various publications. A comparison of energy consumption indicators in France and the European Union leads to a rough estimate of a potential for energy demand efficiency by 2020 of the order of 280 Mtoe on final energy consumption, for the European Union. Chapter III underlines the merits of the Green Paper which are a clear-sighted analysis and a well defined main recommendation

  6. Green-Frag: Energy-Efficient Frame Fragmentation Scheme for Wireless Sensor Networks

    KAUST Repository

    Daghistani, Anas H.

    2013-05-15

    Power management is an active area of research in wireless sensor networks (WSNs). Efficient power management is necessary because WSNs are battery-operated devices that can be deployed in mission-critical applications. From the communications perspective, one main approach to reduce energy is to maximize throughput so the data can be transmitted in a short amount of time. Frame fragmentation techniques aim to achieve higher throughput by reducing retransmissions. Using experiments on a WSN testbed, we show that frame fragmentation helps to reduce energy consumption. We then study and compare recent frame fragmentation schemes to find the most energy-efficient scheme. Our main contribution is to propose a new frame fragmentation scheme that is optimized to be energy efficient, which is originated from the chosen frame fragmentation scheme. This new energy-efficient frame fragmentation protocol is called (Green-Frag). Green-Frag uses an algorithm that gives sensor nodes the ability to transmit data with optimal transmit power and optimal frame structure based on environmental conditions. Green-Frag takes into consideration the channel conditions, interference patterns and level, as well as the distance between sender and receiver. The thesis discusses various design and implementation considerations for Green-Frag. Also, it shows empirical results of comparing Green-Frag with other frame fragmentation protocols in terms of energy efficiency. Green-Frag performance results shows that it is capable of choosing the best transmit according to the channel conditions. Subsequently, Green-Frag achieves the least energy consumption in all environmental conditions.

  10. Green energy market development in Germany: effective public policy and emerging customer demand

    International Nuclear Information System (INIS)

    Wuestenhagen, Rolf; Bilharz, Michael

    2006-01-01

    This paper reviews the development of renewable energy in Germany from 1973 to 2003. It investigates the relative importance of energy policy and green power marketing in shaping the renewable energy market. More than a decade of consistent policy support for renewables under the feed-in law (StrEG) and its successor (EEG) has been an important driver for increasing renewable electricity generation to date, putting the country in a better position than most of its peers when it comes to achieving European Union targets for renewable energy. Green power marketing driven by customer demand, on the other hand, is growing, but has had limited measurable impact so far. We discuss potential intangible benefits of green power marketing and scenarios for future market development. The paper concludes with lessons that can be learned from the German case for policy design and market development in other countries

The ATLAS e-news are an excellent source of information. Appearing now every month they provide a broad, solid view of what is going on. But I'm greedy; I'd love to be "on-line". When the first End-Cap Toroid moved from hall 180 to the pit I was frustrated. I knew that it was happening but I could only get first pictures and reports a few days later. In the meantime the ECT was lowered into the cavern; no information on this available nowhere up to the this issue of the e-news. Here is my dream: an "ATLAS news ticker", i.e. a web page with the news appearing on the day they happen; just one line of information, possibly with a reference to a picture, a person or a report.

    Highlights: • This paper reviews the latest energy efficiency policies of Germany. • We find tangible energy, climate and socioeconomic impacts by 2020. • Notably the building sector stands to benefit economically. • A ‘green energy economy’ needs to build on ambitious energy efficiency policies. - Abstract: Energy efficiency policies play a key role in the transformation to a ‘green energy economy’. In this paper, we take stock of the impacts of the existing energy efficiency policy instruments in Germany and review the energy, environmental and socioeconomic impacts of the country’s latest energy efficiency and climate strategies for the year 2020. We find evidence supporting the findings of other studies that enhanced green energy policies will trigger tangible economic benefits in terms of GDP growth and new jobs even in the short term. Whereas policy makers have already acknowledged and implemented this conclusion in the case of renewable energies, our paper shows that striving for more ambitious energy efficiency policies represents a similar win–win strategy, which should be exploited to a much larger extent.

    2013-01-01

    Taipei, a subtropical modern medium city, is essentially featured with high population density, scarce land, and large traffic flow. Moreover, there are abundant green energy resources reserved in Taipei. If they were fully developed, there would be 13,040 GWh electricity generated per year, resulting in a total of 9.37 million tons of carbon dioxide emissions abatement. The development of the green energy industry in this city not only can bring significant energy-saving and carbon-reducing benefits, but also may create huge derivative business opportunities. For example, the total output values of the solar PV and electric vehicles industries would be as high as 700 billion yuan. In this study, through Strengths, Weaknesses, Opportunities, and Threats (SWOT) analysis, we concluded that the top priorities for Taipei for the development of green energy industries are building energy conservation and electrified transportation, specifically, the following four items: electric vehicles, Light-Emitting Diode (LED) lighting, inverter air conditioning, and Energy Service Company (ESCO). Meanwhile, Taipei is a domestic and international key of politics, transportation, technology, commerce, and finance. Taipei is very likely to become an internationalized green energy industrial hub, achieving the “3E” goals of economic prosperousness, environmental protection, and energy security. -- Highlights: •Building energy conservation and electrified transportation are top priorities. •SWOT analysis applied to systematically conclude four green energy industrial items for Taipei. •Specifically, electric vehicles, LED lighting, inverter air conditioning, and ESCO. •13,040 GWh electricity would be generated per year from Taipei's rich renewables. •The derivative business opportunities would exceed 700 billion yuan

  2. Energy or compost from green waste? - A CO2 - Based assessment

    International Nuclear Information System (INIS)

    Kranert, Martin; Gottschall, Ralf; Bruns, Christian; Hafner, Gerold

    2010-01-01

    Green waste is increasingly extracted from the material recycling chain and, as a result of the financial subsidy arising from the German renewable energy law for the generation of energy from renewable raw materials; it is fed into the energy recovery process in biomass power stations. A reduction in climate relevant gases is also linked to the material recovery of green waste - in particular when using composts gained from the process as a new raw material in different types of potting compost and plant culture media as a replacement for peat. Unlike energy recovery, material valorisation is not currently subsidised. Through the analysis of material and energy valorisation methods for green waste, with particular emphasis on primary resource consumption and CO 2 -balance, it could be determined that the use of green waste for energy generation and its recovery for material and peat replacement purposes can be considered to be on a par. Based on energy recovery or material oriented scenarios, it can be further deduced that no method on its own will achieve the desired outcome and that a combination of recycling processes is more likely to lead to a significant decrease of greenhouse gas emissions.

  3. A Hybrid Energy Sharing Framework for Green Cellular Networks

    KAUST Repository

    Farooq, Muhammad Junaid

    2016-12-09

    Cellular operators are increasingly turning towards renewable energy (RE) as an alternative to using traditional electricity in order to reduce operational expenditure and carbon footprint. Due to the randomness in both RE generation and mobile traffic at each base station (BS), a surplus or shortfall of energy may occur at any given time. To increase energy selfreliance and minimize the network’s energy cost, the operator needs to efficiently exploit the RE generated across all BSs. In this paper, a hybrid energy sharing framework for cellular network is proposed, where a combination of physical power lines and energy trading with other BSs using smart grid is used. Algorithms for physical power lines deployment between BSs, based on average and complete statistics of the net RE available, are developed. Afterwards, an energy management framework is formulated to optimally determine the quantities of electricity and RE to be procured and exchanged among BSs, respectively, while considering battery capacities and real-time energy pricing. Three cases are investigated where RE generation is unknown, perfectly known, and partially known ahead of time. Results investigate the time varying energy management of BSs and demonstrate considerable reduction in average energy cost thanks to the hybrid energy sharing scheme.

  4. Green and energy-efficient methods for the production of metallic nanoparticles

    2015-12-01

    Full Text Available In the last decade, researchers paid great attention to the concept of “Green Chemistry”, which aims at development of efficient methods for the synthesis of nanoparticles (NPs in terms of the least possible impact on human life and environment. Generally, several reagents including precursors, reducing agents, stabilizing agents and solvents are used for the production of NPs and in some cases, energy is needed to reach the optimum temperature for reduction. Therefore, to develop a green approach, researchers had the opportunity to investigate eco-friendly reagents and new energy transfer techniques. In order to substitute the harmful reagents with green ones, researchers worked on different types of saccharides, polyols, carboxylic acids, polyoxometalates and extracts of various plants that can play the role of reducers, stabilizers or solvents. Also, there are some reports on using ultraviolet (UV, gamma and microwave irradiation that are capable of reducing and provide uniform heating. According to the literature, it is possible to use green reagents and novel energy transfer techniques for production of NPs. However, these new synthesis routes should be optimized in terms of performance, cost, product quality (shape and size distribution and scale-up capability. This paper presents a review on most of the employed green reagents and new energy transfer techniques for the production of metallic NPs.

    The use of exergy is described as a measure for identifying and explaining the benefits of green energy and technologies, so the benefits can be clearly understood and appreciated by experts and non-experts alike, and the utilization of green energy and technologies can be increased. Exergy can be used to assess and improve energy systems, and can help better understand the benefits of utilizing green energy by providing more useful and meaningful information than energy provides. Exergy clearly identifies efficiency improvements and reductions in thermodynamic losses attributable to green technologies. Exergy can also identify better than energy the environmental benefits and economics of energy technologies. Exergy should be utilized to engineers and scientists, as well as decision and policy makers, involved in green energy and technologies. (author)

    The main goal of Green Flash is to design and build a prototype for a Real-Time Controller (RTC) targeting the European Extremely Large Telescope (E-ELT) Adaptive Optics (AO) instrumentation. The E-ELT is a 39m diameter telescope to see first light in the early 2020s. To build this critical component of the telescope operations, the astronomical community is facing technical challenges, emerging from the combination of high data transfer bandwidth, low latency and high throughput requirements, similar to the identified critical barriers on the road to Exascale. With Green Flash, we will propose technical solutions, assess these enabling technologies through prototyping and assemble a full scale demonstrator to be validated with a simulator and tested on sky. With this R&D program we aim at feeding the E-ELT AO systems preliminary design studies, led by the selected first-light instruments consortia, with technological validations supporting the designs of their RTC modules. Our strategy is based on a strong interaction between academic and industrial partners. Components specifications and system requirements are derived from the AO application. Industrial partners lead the development of enabling technologies aiming at innovative tailored solutions with potential wide application range. The academic partners provide the missing links in the ecosystem, targeting their application with mainstream solutions. This increases both the value and market opportunities of the developed products. A prototype harboring all the features is used to assess the performance. It also provides the proof of concept for a resilient modular solution to equip a large scale European scientific facility, while containing the development cost by providing opportunities for return on investment.

    Full Text Available The paper deals with the greening of tax systems in the European Union (EU, and reviews the achievements of the Baltic States in relation to greening their tax systems and implementing the sustainable energy development goals set by the EU’s energy policies. Environmental taxes promote sustainable energy development, as they allow internalizing the external costs of atmospheric pollution in the energy sector. Energy production and consumption are a major source classical pollutants and greenhouse gas (GHG emissions. Almost of the all EU member states (MS apply pollution taxes as the most important economic tool for mitigating the environmental impacts of various economic activities. Considering the importance of the energy sector in terms of its contributions to total atmospheric emissions in the EU, it is supposed that environmental taxes are important drivers of sustainable energy development. Environmental taxes, as the main tool for the integration of negative externalities that are related to atmospheric pollution, are imposed to create incentives for reducing fossil fuel consumption and switching to renewable energy sources or fuels that have a lower carbon content and thus cause less pollution. The paper presents a comparative assessment of the impact of environmental taxes on sustainable energy development indicators in three selected countries from the Baltic region (Lithuania, Latvia, and Estonia during the period 2005–2015, and reveals the role that the greening of tax systems has had on implementing sustainable energy development targets in the Baltic States.

  11. Red light for Green Paper: The EU policy on energy efficiency

    2007-01-01

    The EU Green Paper on energy efficiency calls for action to decrease energy use and thus achieve increased competitiveness, fulfil the environmental targets and increase security of supply. In this comment, we examine the role the EU Commission suggest that energy efficiency, and policies supporting energy efficiency, takes. The policies and the suggestions are qualitatively elaborated upon in the light of the goal of a common European electricity market. We suggest that the rationales for the energy efficiency measures are weak, and that the suggested goals of increased competitiveness, environmental targets, and security of supply are best reached with the direct measures especially designed for each goal. Some of the energy efficiency measures may counter-act other direct policies. Further, The Green Paper measures may prove detrimental to the European Electricity market insofar as the policies suggested could lead to a policy fatigue among the electricity consumers

    People are relying upon oil for primary energy and this will continue for a few more decades. Other conventional sources may be more enduring, but are not without serious disadvantages. The renewable energy resources are particularly suited for the provision of rural power supplies and a major advantage is that equipment such as flat plate solar driers, wind machines, etc., can be constructed using local resources. Without the advantage results from the feasibility of local maintenance and the general encouragement such local manufacture gives to the buildup of small-scale rural based industry. This communication comprises a comprehensive review of energy sources, the environment and sustainable development. It includes the renewable energy technologies, energy efficiency systems, energy conservation scenarios, energy savings in greenhouses environment and other mitigation measures necessary to reduce climate change. This study gives some examples of small-scale energy converters, nevertheless it should be noted that small conventional, i.e., engines are currently the major source of power in rural areas and will continue to be so for a long time to come. There is a need for some further development to suit local conditions, to minimise spares holdings, to maximise the interchangeability of the engine parts, and of the engine applications. Emphasis should be placed on full local manufacture. It is concluded that renewable environmentally friendly energy must be encouraged, promoted, implemented and demonstrated by a full-scale plant (device) especially for use in remote rural areas.

    Greening the Grid provides technical assistance to energy system planners, regulators, and grid operators to overcome challenges associated with integrating variable renewable energy into the grid. Coordinating balancing area operation can promote more cost and resource efficient integration of variable renewable energy, such as wind and solar, into power systems. This efficiency is achieved by sharing or coordinating balancing resources and operating reserves across larger geographic boundaries.

    2015-02-11

    This paper describes an approach piloted in the Kasserine region of Tunisia to increase the energy efficiency of the distribution of vaccines and temperature sensitive drugs. The objectives of an approach, known as the 'net zero energy' (NZE) supply chain were demonstrated within the first year of operation. The existing distribution system was modified to store vaccines and medicines in the same buildings and to transport them according to pre-scheduled and optimized delivery circuits. Electric utility vehicles, dedicated to the integrated delivery of vaccines and medicines, improved the regularity and reliability of the supply chains. Solar energy, linked to the electricity grid at regional and district stores, supplied over 100% of consumption meeting all energy needs for storage, cooling and transportation. Significant benefits to the quality and costs of distribution were demonstrated. Supply trips were scheduled, integrated and reliable, energy consumption was reduced, the recurrent cost of electricity was eliminated and the release of carbon to the atmosphere was reduced. Although the initial capital cost of scaling up implementation of NZE remain high today, commercial forecasts predict cost reduction for solar energy and electric vehicles that may permit a step-wise implementation over the next 7-10 years. Efficiency in the use of energy and in the deployment of transport is already a critical component of distribution logistics in both private and public sectors of industrialized countries. The NZE approach has an intensified rationale in countries where energy costs threaten the maintenance of public health services in areas of low population density. In these countries where the mobility of health personnel and timely arrival of supplies is at risk, NZE has the potential to reduce energy costs and release recurrent budget to other needs of service delivery while also improving the supply chain.

    This paper examines the relationship between China’s total energy consumption growth and GGDP growth based on the data of 1997-2016. With path analysis employed, the direct and indirect influence on GGDP growth rate exerted by several energy consumption ratios as well as the relationship among them is explored. Furtherly, the author determines how much each of these ratios contributes to GGDP. This research suggests that proportion of natural gas consumption and that of other energy consumption are the two major drivers of GGDP growth, while coal and oil consumption proportion inhibits GGDP Growth. Specifically, increasing the proportion of natural gas consumption contributes the most to GGDP growth.

  3. High-Capacity Hydrogen-Based Green-Energy Storage Solutions For The Grid Balancing

    Science.gov (United States)

    D'Errico, F.; Screnci, A.

    One of the current main challenges in green-power storage and smart grids is the lack of effective solutions for accommodating the unbalance between renewable energy sources, that offer intermittent electricity supply, and a variable electricity demand. Energy management systems have to be foreseen for the near future, while they still represent a major challenge. Integrating intermittent renewable energy sources, by safe and cost-effective energy storage systems based on solid state hydrogen is today achievable thanks to recently some technology breakthroughs. Optimized solid storage method made of magnesium-based hydrides guarantees a very rapid absorption and desorption kinetics. Coupled with electrolyzer technology, high-capacity storage of green-hydrogen is therefore practicable. Besides these aspects, magnesium has been emerging as environmentally friend energy storage method to sustain integration, monitoring and control of large quantity of GWh from high capacity renewable generation in the EU.

    The introduction of energy storage technologies to the grid could enable greater integration of renewables, improve system resilience and reliability, and offer cost effective alternatives to transmission and distribution upgrades. The integration of energy storage systems into the electrical grid can lead to different environmental outcomes based on the grid application, the existing generation mix, and the demand. Given this complexity, a framework is needed to systematically inform design and technology selection about the environmental impacts that emerge when considering energy storage options to improve sustainability performance of the grid. To achieve this, 12 fundamental principles specific to the design and grid application of energy storage systems are developed to inform policy makers, designers, and operators. The principles are grouped into three categories: (1) system integration for grid applications, (2) the maintenance and operation of energy storage, and (3) the design of energy storage systems. We illustrate the application of each principle through examples published in the academic literature, illustrative calculations, and a case study with an off-grid application of vanadium redox flow batteries (VRFBs). In addition, trade-offs that can emerge between principles are highlighted.

    From a room electric bulb to the gigantic backbone networks energy savings have now become a matter of considerable concern. Issues such as resource depletion, global warming, high energy consumptions and environmental threats gave birth to the idea of green networking. Serious efforts have been done in this regard on large scale in the ICT sector. In this work first we give an idea of how and why this modern technology emerged. We then formulate a precise definition of the term green technology. We then discuss some leading techniques which are promising to produce green-results when implemented on real time network systems. These technologies are viewed from different perspectives e.g. hardware implementations, software mechanisms and protocol changing etc. We then compare these techniques based on some pivotal points. The main conclusion is that a detailed comparison is needed for selecting a technology to implement on a network system. (author)

    This paper investigates the role of standardization for green economic change using energy efficiency in buildings as a case. Innovation research on standards tends to focus on the competition between competing emerging standards as well as the economic impacts of these. The idea pursued here...... energy efficiency becomes an issue in standardization work using buildings as a case. The paper seeks more specifically to investigate the rise of building related standards generally over time as well as in different technical areas and geographic regions. The hypothesis pursued in this paper...... is that the rise of the green economy can only take place accompanied by considerable institution formation in the form of standards. In this sense, the presence of standards may be seen as an important indicator on the maturity of the greening of the economy. The paper presents early empirical work...

  8. Study of a conceptual nuclear energy center at Green River, Utah: water allocation issues

    International Nuclear Information System (INIS)

    Harper, N.J.

    1982-04-01

    According to preliminary studies, operation of a nine-reactor Nuclear Energy Center near Green River, Utah would require the acquisition of 126,630 acre-feet per year. Groundwater aquifers are a potential source of supply but do not present a viable option at this time due to insufficient data on aquifer characteristics. Surface supplies are available from the nearby Green and San Rafael Rivers, tributaries of the Colorado River, but are subject to important constraints. Because of these constraints, the demand for a dependable water supply for a Nuclear Energy Center could best be met by the acquisition of vested water rights from senior appropriators in either the Green or San Rafael Rivers. The Utah Water Code provides a set of procedures to accomplish such a transfer of water rights

    2001-04-01

    The Green Paper ''Towards a European strategy for the security of energy supply in Europe'', published in 2002, gives a clear priority to energy efficiency and renewable. Although it is not a legislative document, it is accepted by the main actors as a reference for all energy related actions. Energie-Cites welcomes the Green Paper. This document gives a clear review of the energy context in Europe and raises fundamental questions, in particular, the place given to energy demand management, presented as the priority policy to ensure security of supply and compliance with the European Union international commitments. However, they precise three important points. It is indispensable that potential energy savings be quantified so as to emphasize the importance of a resource that has always been underestimated. By the same token, the ''demand management'' option presented in the Green Paper would gain in credibility if several alternative scenarios were proposed, the impact and the conditions for the success of such a policy being then more clearly apparent. A policy with a stronger focus on demand management and renewable energy requires one to redirect attention towards a different set of players. (A.L.B.)

    This paper uses System Dynamics (SD) simulation to investigate the concept green logistics in terms of energy efficiency in automotive industry. The car manufacturing industry is considered to be one of the highest energy consuming industries. An efficient decision making model is proposed that capture the impacts of strategic decisions on energy consumption and environmental sustainability. The sources of energy considered in this research are electricity and fuel; which are the two main types of energy sources used in a typical vehicle assembly plant. The model depicts the performance measurement for process- specific energy measures of painting, welding, and assembling processes. SD is the chosen simulation method and the main green logistics issues considered are Carbon Dioxide (CO2) emission and energy utilization. The model will assist decision makers acquire an in-depth understanding of relationship between high level planning and low level operation activities on production, environmental impacts and costs associated. The results of the SD model signify the existence of positive trade-offs between green practices of energy efficiency and the reduction of CO2 emission.

    Renewable energy sources that are commonly used in buildings include solar energy, wind energy and rainwater collection. High quality environmentally responsive residential buildings are designed to provide good insulation in winter and solar shading in summer. However, this study demonstrated that the green energy design in residential buildings is not usually well integrated. For example, windows with clear double or triple glazed glass, allow good penetration of sunlight during the day in winter, but are not further dynamically insulated for when the sun goes down to avoid heat loss from the building. Additionally, good solar static shading devices often block much needed daylight on cloudy winter days. These examples emphasize the lack of an integrated approach to gain the best advantage of green energies and to minimize energy costs in residential buildings. This study addressed issues facing the integrated approach with particular reference to the design of a small residential building in rural Beijing. The design included a new approach for interpreting a traditional Beijing court yard house in the modern Beijing rural context, while integrating multi-responding innovative green energy applications derived from first principles. This paper also presented a proposal for a village house in Hong Kong to harvest as much renewable energies as possible, primarily wind energy and solar energy, that come into contact with the building. The purpose was to work towards a renewable energy approach for buildings, namely the Bireth approach, which will benefit practically all houses by making them zero energy houses. The paper described the feasibility of integrating renewable energies in buildings to fulfill performance requirements such improving ventilation, providing warm interiors, drying clothes, or storing solar and wind energies into power batteries. The challenges facing the development of a proposed micro solar hot air turbine were also presented. 15 refs., 6

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

  14. Building energy modeling for green architecture and intelligent dashboard applications

    Science.gov (United States)

    DeBlois, Justin

    Buildings are responsible for 40% of the carbon emissions in the United States. Energy efficiency in this sector is key to reducing overall greenhouse gas emissions. This work studied the passive technique called the roof solar chimney for reducing the cooling load in homes architecturally. Three models of the chimney were created: a zonal building energy model, computational fluid dynamics model, and numerical analytic model. The study estimated the error introduced to the building energy model (BEM) through key assumptions, and then used a sensitivity analysis to examine the impact on the model outputs. The conclusion was that the error in the building energy model is small enough to use it for building simulation reliably. Further studies simulated the roof solar chimney in a whole building, integrated into one side of the roof. Comparisons were made between high and low efficiency constructions, and three ventilation strategies. The results showed that in four US climates, the roof solar chimney results in significant cooling load energy savings of up to 90%. After developing this new method for the small scale representation of a passive architecture technique in BEM, the study expanded the scope to address a fundamental issue in modeling - the implementation of the uncertainty from and improvement of occupant behavior. This is believed to be one of the weakest links in both accurate modeling and proper, energy efficient building operation. A calibrated model of the Mascaro Center for Sustainable Innovation's LEED Gold, 3,400 m2 building was created. Then algorithms were developed for integration to the building's dashboard application that show the occupant the energy savings for a variety of behaviors in real time. An approach using neural networks to act on real-time building automation system data was found to be the most accurate and efficient way to predict the current energy savings for each scenario. A stochastic study examined the impact of the

    International Nuclear Information System (INIS)

    Winfield, Mark; Dolter, Brett

    2014-01-01

    This paper examines the debates around the Ontario's Green Energy and Green Economy Act (GEGEA) as an energy and economic development strategy through comparative public policy and discourse analysis approaches. The evidence regarding the economic impacts of the GEGEA is found to be almost entirely based on the results of economic modeling exercises. Critics and supporters of the legislation have arrived at very different conclusions through such exercises. These outcomes are similar to those seen in other jurisdictions pursuing renewable energy initiatives, such as Feed In Tariffs (FITs), renewables obligations and portfolio standards. A discourse analysis approach is employed to examine the reasons for the different conclusions being reached over the impacts of renewable energy initiatives. Differences in modeling approaches and assumptions are found to reflect differences in ideational perspectives on the part of the modelers with respect to the appropriate roles of markets and the state and the relationship between economic development and environmental sustainability in public policy. The paper concludes with suggestions regarding the gathering and availability of information regarding economic development in the renewable energy sector, and a discussion of potential ways to strengthen future efforts to understand the economic and environmental impact of renewable energy initiatives. - Highlights: • The discourse surrounding renewable energy initiatives is embedded within wider ideological debates. • The information that underpins the debates in Ontario is the result of economic modelling, not empirical data. • All of the existing modelling efforts suffer from significant shortcomings. • FITS are seen as politically feasible mechanisms for correcting biases in favour of conventional technologies. • The province's long-term commitment of renewable energy development is now uncertain

    Full Text Available The United Nations has designated the year 2012 as the international year of sustainable energy. Today, we are seeing a rise in global awareness of energy consumption and environmental problems. Many nations have launched different programs to reduce the energy consumption in residential and commercial buildings to seek lower-carbon energy solutions. We are talking about the future green and smart houses. The subject of smart/green houses is not one of “why,” but rather “how,” specifically: “how making the future house more energy efficient.” The use of the renewable energy, the technology and the services could help us to answer this question. Intelligent home energy management is an approach to build centralized systems that deliver application functionality as services to end-consumer applications. The objective of this work is to develop a smart and robust controller for house energy consumption with maximizing the use of solar energy and reducing the impact on the power grid while satisfying the energy demand of house appliances. We proposed a fuzzy-based energy management controller in order to reduce the consumed energy of the building while respecting a fixed comfort.

    There is a large gap between the production and demand for energy from alternative fuel and alternative renewable energy sources. The sustainability of humanity, as we know it, directly depends on the ability to secure affordable fuel, food, and freshwater. NASA Glenn Research Center (Glenn) has initiated a laboratory pilot study on using biofuels as viable alternative fuel resources for the field of aviation, as well as utilizing wind and solar technology as alternative renewable energy resources. The GreenLab Research Facility focuses on optimizing biomass feedstock using algae and halophytes as the next generation of renewable aviation fuels. The unique approach in this facility helps achieve optimal biomass feedstock through climatic adaptation of balanced ecosystems that do not use freshwater, compete with food crops, or use arable land. In addition, the GreenLab Research Facility is powered, in part, by alternative and renewable energy sources, reducing the major environmental impact of present electricity sources. The ultimate goal is to have a 100 percent clean energy laboratory that, when combined with biomass feedstock research, has the framework in place for a self-sustainable renewable energy ecosystem that can be duplicated anywhere in the world and can potentially be used to mitigate the shortage of food, fuel, and water. This paper describes the GreenLab Research Facility at Glenn and its power and energy sources, and provides recommendations for worldwide expansion and adoption of the facility s concept.

    The energy consumption of backbone networks has become a primary concern for network operators and regulators due to the pervasive deployment of wired backbone networks to meet the requirements of bandwidth-hungry applications. While traditional optimization of IGP link weights has been used in IP based load-balancing operations, in this paper we introduce a novel link weight setting algorithm, the Green Load-balancing Algorithm (GLA), which is able to jointly optimize both energy efficiency ...

    We analyze the energy spectrum and propagation of electrons in a quantum wire on a 2D host medium in a normal magnetic field, representing the wire by a 1D Dirac delta function potential which would support just a single subband state in the absence of the magnetic field. The associated Schroedinger Green's function for the quantum wire is derived in closed form in terms of known functions and the Landau quantized subband energy spectrum is examined.

    2015-10-19

    Modern smartphones are limited by their short battery life. The advancement of the graphical performance is considered as one of the main reasons behind the massive battery drainage in smartphones. In this paper we present a novel implementation of the GPUFreq Scaling Governors, a Dynamic Voltage and Frequency Scaling (DVFS) model implemented in the Android Linux kernel for dynamically scaling smartphone Graphical Processing Units (GPUs). The GPUFreq governors offer users multiple variations and alternatives in controlling the power consumption and performance of their GPUs. We implemented and evaluated our model on a smartphone GPU and measured the energy performance using an external power monitor. The results show that the energy consumption of smartphone GPUs can be significantly reduced with a minor effect on the GPU performance.

    The British government backs the project of building about 10 new nuclear power plants. The main reason is that renewable energies appear to be insufficiently advanced, in technical terms, to rely solely on them for the production of electricity. The British government has warned that the operators will have to pay entirely the dismantlement costs of these new nuclear plants and a fair part of the cost of the management of radioactive wastes they generate.

    As a follow-up activity of the Macedonian First National Communication under the UNFC-CC, Technology Needs Assessment is conducted, evaluating by GACMO model the measures related mainly to energy efficient and renewable energy technologies. An abatement cost curve is constructed and used as an illustrative tool for recognizing priorities in GHG abatement policy. About half of the measures are shown to be of 'win-win' type, reducing 3% of the baseline GHG emissions, while the total reduction which can be achieved by all measures amounts to 20%. For each measure difficulties for implementation are identified, being the highest for the measures with largest GHG abatement potential. Generally, these difficulties include lack of financing and low prospects for attracting foreign investments as well as legislative and administrative barriers. It must be recognized that climate change issues could not be of high priority in a country with economy in transition. Consequently, in our case the main issues which should be integrated within the framework of ongoing transition reforms, in an effort to implement a GHG emission reduction policy, would be: institutional capacity building, attracting foreign investment, emphasis on energy efficiency and considering the switch toward less carbon intensive fuels.

    The labor market implications of large investment into renewable energy (RE) are analyzed in this text. Although a growing RE industry can be observed in Germany the overall effect of large increases of RE based electricity and heat generating technologies on the German economy require a careful model based analysis. The applied model PANTA RHEI has been used among others to evaluate the German energy concept in 2010. It takes positive and negative impacts of RE into account. The paper shows the overall effects under different assumptions for fossil fuel prices, domestic installations and international trade. The results are sensitive to assumptions on the development of RE world markets and German exports to these markets. Almost all of these scenarios exhibit positive net employment effects. Under medium assumptions net employment of RE expansion will reach around 150 thousand in 2030. Only with assumptions for German RE exports below today's level, net impacts are slightly negative. Gross employment will increase from 340 thousand in 2009 to between 500 and 600 thousand in 2030. - Highlights: ► This paper analyzes labor market implications of large investment into renewable energy (RE) in Germany. ► It shows the overall effects under different assumptions. ► The development of world markets and German RE exports are very important. ► Net employment of RE expansion will reach around 150 thousand in 2030. ► Gross employment will increase to between 500 and 600 thousand in 2030.

    Buildings consume nearly 40% of primary energy production globally. Certified green buildings substantially reduce energy consumption on a per square foot basis and they also focus on indoor environmental quality. However, the co-benefits to health through reductions in energy and concomitant reductions in air pollution have not been examined.We calculated year by year LEED (Leadership in Energy and Environmental Design) certification rates in six countries (the United States, China, India, Brazil, Germany, and Turkey) and then used data from the Green Building Information Gateway (GBIG) to estimate energy savings in each country each year. Of the green building rating schemes, LEED accounts for 32% of green-certified floor space and publically reports energy efficiency data. We employed Harvard's Co-BE Calculator to determine pollutant emissions reductions by country accounting for transient energy mixes and baseline energy use intensities. Co-BE applies the social cost of carbon and the social cost of atmospheric release to translate these reductions into health benefits. Based on modeled energy use, LEED-certified buildings saved $7.5B in energy costs and averted 33MT of CO 2 , 51 kt of SO 2 , 38 kt of NO x , and 10 kt of PM 2.5 from entering the atmosphere, which amounts to $5.8B (lower limit = $2.3B, upper limit = $9.1B) in climate and health co-benefits from 2000 to 2016 in the six countries investigated. The U.S. health benefits derive from avoiding an estimated 172-405 premature deaths, 171 hospital admissions, 11,000 asthma exacerbations, 54,000 respiratory symptoms, 21,000 lost days of work, and 16,000 lost days of school. Because the climate and health benefits are nearly equivalent to the energy savings for green buildings in the United States, and up to 10 times higher in developing countries, they provide an important and previously unquantified societal value. Future analyses should consider these co-benefits when weighing policy

  12. Contribution of green labels in electricity retail markets to fostering renewable energy

    In European countries, retailers are obliged to disclose the energy source and the related environmental impacts of their portfolio over the preceding year. The electricity supplied in the Dutch retail market is presented as renewable energy for 34%, but this relatively high share is for 69% based on certificates (Guarantees of Origin) which are imported from in particular Norway. The certificates are used to sell green electricity to consumers. The premium for green electricity which is actually paid by Dutch consumers is no more than a few percentages of the retail price. The low level of this premium is related to the abundant supply of certificates at low marginal costs from Norway. This also means that the premium for green electricity is too low to give an incentive for investments in new capacity. Hence, the current labelling system for renewable electricity is mainly valuable, besides being an instrument for tracking and tracing of renewable energy, as a marketing instrument for electricity retailers. The effectiveness of Guarantees of Origin as a policy instrument to foster renewable electricity sources is weak. This effectiveness can be raised by implementing restrictions on the international trade or the issuance of new certificates. - Highlights: • In Europe, electricity retailers are obliged to disclose the energy source. • In the Netherlands, most renewable energy is based on imported certificates. • The certificates system does not result in more renewable energy. • Restrictions on international trade may improve the effectiveness.

    The development of transportation systems that use new and sustainable energy technologies is of utmost importance due to the possible future shortfalls that current transportation modes will encounter because of increased volume and costs. The introduction and further research and development of new transportation and energy systems by materials researchers at the National Aeronautics and Space Administration (NASA) Langley Research Center (LaRC) and the Department of Transportation are discussed in this Technical Memorandum. In this preliminary study, airship concepts were assessed for cargo transportation using various green energy technologies capable of 24-hour operation (i.e., night and day). Two prototype airships were successfully constructed and tested at LaRC to demonstrate their feasibility: one with commercially available solar cells for operation during the daytime and one with microwave rectennas (i.e., rectifying antennas) developed in-house for night-time operation. The test results indicate the feasibility of a cargo transportation airship powered by new green energy sources and wireless power technology. Future applications will exploit new green energy sources that use materials and devices recently developed or are in the process of being developed at LaRC. These include quantum well SiGe solar cells; low, mid-, and high temperature thermoelectric modules; and wireless microwave and optical rectenna devices. This study examines the need and development of new energy sources for transportation, including the current status of research, materials, and potential applications.

    Metes, Mircea

    2006-01-01

    At present the energy is for European Union officials an issue of top priority. In the beginning of 2006 the natural gas crisis between Russia and Ukraine remembered menacingly to the Europeans that energy supply of the continent depends decisively on importation from other geographic areas and that these importation raise risks of a great variety. In addition to the power problems, disastrous effects on the economy, human life and eco-systems appeared to have the climate changes produced by fossil fuel burning. Consequently, a common energetic policy of Europe should be targeted at three main objectives: sustainability, competitiveness and security of supply. Six directions of action were identified: 1. EU must finalize the construction of internal European gas and electricity market; 2. EU should ensure that its energy market guaranties the security of supply under a solidary policy of the member states; 3. It is necessary that a large debate to have place about different sources of energy including the problems of costs and impact on climatic change, security and supply competitiveness and sustainability; 4. EU should approach the climatic change issues in agreement with the objectives established at Lisbon conference aiming at placing EU in the forefront of technological and scientific progress; 5. A strategic plan concerning the energy technology; 6. A common foreign policy in the field of energy. It is worthy to stress that the present Green Paper of EU has a manifestly different position concerning the nuclear energy with respect to the prior Green Paper of November 2000. While, in 2000 the EU Commission viewed the nuclear energy as being 'in limbo', in the 2006 version the Commission declared the nuclear energy as the most important source of power in Europe without CO 2 emissions. It is stated that all the energy options should be kept open while the Europe states have the right to establish their own energy mix, which they consider optimal, and in which

  15. Simultaneous attainment of energy goals by means of green certificates and emission permits

    2003-01-01

    We discuss the analytical effects of introducing emission permits and green certificates and the corresponding quotas as regulatory mechanisms to, respectively, reduce emissions from electricity production and ensure a certain deployment of renewable energy. The different case studies in this paper show that both instruments can be used in order to reach an emission goal or a goal of renewable energy. However, the combination of these instruments and the way they are used, is shown to be important for the price faced by consumers. It is shown that the effect on the consumer price is not an unambiguous increase with the introduction of a green quota. There is a choice between quotas leading to a lower consumer price and quotas leading to a higher consumer price. As a result of this it is shown that it is always optimal to reach a renewable energy deployment goal by the use of green certificates. However, to reach an emission goal it is sometimes most favourable, with respect to consumer prices, to use green certificates and sometimes to use emission permits

    Blue Line Innovations Inc. is working with leading electric utilities and regulatory agencies to provide smart-home technologies to consumers for demand-side management. Their latest product is the PowerCost Monitor, a real-time feedback product that help households understand and reduce the amount of electricity they use. The monitor, which reveals electricity use in real-time by both total and current cost and kilowatt hour, uses wireless encrypted technology to send usage information from an outside meter to an in-home display. The small detector/transmitter can be easily installed to an existing household electro-mechanical utility meter by the homeowner without an electrician or service disruption. Studies have shown that when domestic users are provided with real-time feedback on electricity usage, they can reduce their energy bills by as much as 20 per cent. This in-home measuring and reporting unit helps customers make decisions about changing their usage habits, purchasing electricity-saving light and appliances and conserving energy. In a demonstration project, Hydro-One installed PowerCost Monitors in the homes of Hydro One customers in Ontario in July 2004. The objective was to determine the extent of changes in customer behaviour and reductions in electricity consumption resulting from direct real-time feedback information on electricity consumption. Other demonstration projects have been launched in conjunction with CEA Technologies Inc., Natural Resources Canada, Newfoundland Power and BC hydro to install the monitors in homes on both coasts of Canada. Governments, utilities, communities and individuals are recognizing that saving energy is a critical factor to sustainable development by conserving natural resources and reducing pollution. A list of suggestions for reducing electricity use in lighting, kitchens, laundry and heating and cooling were also presented. 1 fig.

    2008-01-01

    Green power products may be seen as a means of fostering renewable energy sources (RES) because they create and channel consumer demand for environmentally sound power generation. Turkey also has a large potential for renewable energy exploitation in a number of areas. Clean, domestic and renewable energy is commonly accepted as the key for future life, not only for Turkey but also for the world. The renewable energy contribution in the total primary energy production is insignificant. The alternative and renewable energy systems have been neglected so far in Turkey but must be included in the new energy programs. In this context, Renewable Energy Law was enacted in 2005 in order to encourage renewable-based generation in competitive market conditions. Supporting mechanisms such as feed-in tariffs and purchase obligation are defined in the law, in conformity with the EU legislation and practice. These mechanisms are envisaged to facilitate the development of power plants based on RES. (author)

    Green obligations are an important lever for the financing of energy transition as they allow enterprises and public bodies to finance their environmental projects, notably their investments and infrastructures. They comprise a reporting on financed investments and the description of the green characteristic of the financed projects. This publication proposes an overview of this arrangement which has been introduced in 2007 and has been displaying a strong development since 2013, and was also boosted by the COP21. The market diversification and internationalisation are outlined, and concern large companies, private banks, and local and regional communities, with rather well identified objectives. The publication outlines that the precise definition of green obligations is however still missing, that private and public initiatives are emerging to structure this market. It finally outlines the need for a harmonisation of reporting standards

    As country after country abandons, curtails or reneges on once-generous support for renewable energy, Europe is beginning to realise that its green energy strategy is dying on the vine. Green dreams are giving way to hard economic realities. Slowly but gradually, Europe is awakening to a green energy crisis, an economic and political debacle that is entirely self-inflicted. The mainstream media, which used to encourage the renewable energies push enthusiastically, is beginning to sober up too. With more and more cracks beginning to appear, many newspapers are returning to their proper role as the fourth estate, exposing the pitfalls of Europe's green-energy gamble and opening their pages for thorough analysis and debate. Today, European media is full of news and commentary about the problems of an ill-conceived strategy that is becoming increasingly shaky and divisive

    2008-01-01

    Time-dependent quantum mechanics provides an intuitive picture of particle propagation in external fields. Semiclassical methods link the classical trajectories of particles with their quantum mechanical propagation. Many analytical results and a variety of numerical methods have been developed to solve the time-dependent Schroedinger equation. The time-dependent methods work for nearly arbitrarily shaped potentials, including sources and sinks via complex-valued potentials. Many quantities are measured at fixed energy, which is seemingly not well suited for a time-dependent formulation. Very few methods exist to obtain the energy-dependent Green function for complicated potentials without resorting to ensemble averages or using certain lead-in arrangements. Here, we demonstrate in detail a time-dependent approach, which can accurately and effectively construct the energy-dependent Green function for very general potentials. The applications of the method are numerous, including chemical, mesoscopic, and atomic physics

    The production of energy from renewable and waste materials is an attractive alternative to the conventional agricultural feed stocks such as corn and soybean. This paper describes an approach to extract oil from spent coffee grounds and to further transesterify the processed oil to convert it into biodiesel. This process yields 10-15% oil depending on the coffee species (Arabica or Robusta). The biodiesel derived from the coffee grounds (100% conversion of oil to biodiesel) was found to be stable for more than 1 month under ambient conditions. It is projected that 340 million gallons of biodiesel can be produced from the waste coffee grounds around the world. The coffee grounds after oil extraction are ideal materials for garden fertilizer, feedstock for ethanol, and as fuel pellets.

    Quantifying potential renewable energy sources from tourist attractions is a pivotal initial step in developing energy policies and strategies for low-carbon tourist industry development. Although solar energy and wind power have been in use for providing power for tourist attractions, the value of using waste biomass for energy production is still poorly understood. Here we advocate a promising approach that produces energy from green waste created by tourism attractions currently existing in large numbers and is still increasing dramatically. Using the Yangtze River Delta (YRD) of China as an example, we evaluated the potential of utilizing green waste to produce energy from 385 tourist attractions in 16 cities of this region. Our results showed that the total potential energy production using the green waste biomass was estimated at 6740 TJ/yr (1 TJ=10 12 J) with an average of 137 GJ/ha/yr (1 GJ=10 9 J), accounting for 6% (the average of the Yangtze River Delta, some scenic areas up to 93%) of YRD′s tourism industry′s energy consumption in 2008. The use of green waste for energy production is possible using current technology and could result in a win–win approach by reducing waste and increasing the renewable energy yields. -- Highlights: •Green waste from tourist attractions could help offset the tourist′s fossil fuel consumption. •Economic, technical, and social feasibility analysis of green waste for energy production. •Puts forward policy recommendations, from management regulations, public support etc

    The Green Paper sets forth a series of questions regarding the security of energy in Europe. It addresses the issue of increased consumption and dependence on oil, and sketches out possible strategies for broadening the energy supply and slowing global warming. It draws an alarming picture of the EU energy situation. If no action is taken, it predicts that the EU energy dependency will climb from 50% in 2000 to 70% in 2030. The particular situation for the main imported fossil fuels is described. This technical paper is particularly devoted to the context, the energy sources, the supply disruption, the energy demand, the fuel balance, the energy technology and the transport of fuel in the EU (transit).

    2014-01-01

    Renewable energy promotion and its cost are at the heart of the energy policy debate in many countries. The question from an economic perspective is how expensive the promotion of renewable sources through price-based incentive schemes is. This paper addresses this issue empirically. We analyze the Spanish electricity market during the period 2008–2012, where renewable energy production rose by 57%. To determine how expensive it was, we first measure the savings due to the spot price reduction driven by the merit order effect and, second, we compute the amount paid as incentives to green energy by the electricity system; the difference between the two is the net cost of green energy to the electricity markets. We present aggregate results for renewable sources as a whole, as well as individual results for each technology. We show that at the initial stages, when renewable capacity was low, green energy promotion paid for itself (2008–2009); however, from 2010 on, when renewable production reached a relatively high level, it started to impose a positive net cost on the system. Finally, we found substantial differences among technologies: wind energy implied the lowest net cost, while solar photovoltaic was the most expensive. - Highlights: • The combination of feed-in tariffs and premiums has been an effective instrument in the promotion of renewable electricity in Spain. • Significant reduction of the daily market price due to RES-E. • Considering the subsidies to RES-E this energy might seem rather expensive for the Spanish electricity system since 2010. • Substantial differences among technologies: wind energy implied the lowest net cost, while solar photovoltaic was the most expensive

    The Green Deal is a major new energy policy designed to support the diffusion of energy efficiency measures in UK homes. This paper provides one of the first empirical examinations of the Green Deal′s success in influencing homeowners’ renovation decisions. Using a repeated measures design in which households were questioned before and after the Green Deal′s launch in January 2013, we assess the policy′s success in raising awareness of energy efficiency. In particular, we test the effectiveness of the Green Deal′s positioning to overcome barriers to renovation among homeowners already interested in or considering energy efficiency measures. Using the innovation decision process (Rogers, 2003) as a conceptual framing of the renovation decision process, we examine whether new information on energy efficiency provided by the Green Deal strengthened intentions and its antecedents. We find that (1) energy efficiency is of potential appeal to all renovators regardless of their attitudes about energy efficiency, (2) energy efficiency opportunities need to be identified in the early stages of renovation when homeowners are thinking about ways to improve their home, and (3) homeowners’ intentions towards energy efficiency are weakened by uncertainty about financial benefits, helping to explain the relatively slow uptake of the Green Deal to-date. - Highlights: • Examines the impact of a major new energy policy, the Green Deal, on intentions towards energy efficiency. • 502 households questioned four months prior to, and seven months after the launch. • Renovating itself is mechanism through which households engage with the Green Deal. • Strengthening beliefs in energy savings accelerates intentions to renovate energy efficiently

  14. Health impact assessment of Ontario's green energy and green economy act. The roles of environmental informatics in sustainability

    Energy Technology Data Exchange (ETDEWEB)

    Rattle, Robert

    2013-07-01

    Renewable energy received a boost in Ontario, Canada with the Green Energy and Green Economy Act (GEGEA), ushering in a new Feed-in-Tariff (FIT) program modelled on programs from Germany, Spain, Denmark and other jurisdictions. Information about lessons learned elsewhere has clearly benefited the Ontario experience. Part of the Ontario program included streamlining the impact assessment process to facilitate the swift development of provincial renewable energy capacities. In this context, the GEGEA has been remarkably successful, generating renewable energy sector capacities, resources, projects and their spin-off benefits in Ontario, along with more sustainable electricity system. Environmentalists along with industry continue to laud the benefits of renewable energy and the GEGEA, and with good reason. Renewable energy generation in Ontario has grown from to 2 per cent in 2012 and is expected to reach 10 per cent in 2013. (orig.)

  15. Stuck between a ROC and a hard place? Barriers to the take up of green energy in the UK

    International Nuclear Information System (INIS)

    Diaz-Rainey, Ivan; Ashton, John K.

    2008-01-01

    This paper examines the UK mechanisms for ensuring future investment in renewable energy through consumer adoption of green energy tariffs and the Renewable Obligation Certificate (ROC) system. Using a national survey and focus groups the stated willingness by UK customers to pay a premium for renewable or green energy and actual take up of such tariffs is assessed. Substantial differences between willingness to pay for and the adoption of green energy tariffs are reported. This disparity is linked to a range of factors including consumer confusion, lack of supply, complexities of constructing 'green source' tariffs under the ROC system and a lack of customer trust. It is concluded that the re-definition of the green energy market in favour of 'green source' tariffs, greater direct compliance with the Renewable Obligation by addressing supply constraints, and efforts in providing clearer information and choices for consumers via a compulsory green energy accreditation scheme are required if willing consumers' are to contribute to investment in renewable energy

    Weaver, R.; Taylor, J.; Burnett, K.; Greenberg, B.

    1982-02-01

    This document constitutes a segment of a feasibility study investigating the ramifications of constructing a nuclear energy center (NEC) in an arid western region. In this phase of the study, the impacts on socioeconomic conditions in the surrounding communities and possible ways of financing and mitigating these impacts were examined. The general conclusion reached is that the socioeconomic impacts of a nuclear energy center in the Green River area of Southeastern Utah would not impose an absolute bar to NEC development. The economy of the NEC impact area would be substantially transformed by the NEC. In particular, Green River city itself would change from its current status as a relatively stable rural economy with an agricultural, mining, and recreation base to a major city with over 20,000 permanent relatively high income residents. The NEC, by itself, would provide a tax base more than adequate to finance required expansion of public facilities and public human service provisions

    Full Text Available In this paper, taking Lushan West Sea highway green rest area in Jiangxi Province of China as the case study, the suitable types, applicability, advantages, and effective methods of solar lighting technologies for highway rest area were determined based on the analysis of characteristics of highway green rest area. It was proved that solar lighting technologies including the natural light guidance system, solar LED lighting, and maximizing natural light penetration were quite suitable for highway rest area in terms of lighting effects and energy and economic efficiency. The illuminance comparison of light guidance system with electrical lighting was made based on the on-site experiment. Also, the feasibility of natural light guidance system was well verified in terms of the lighting demand of the visitor centre in the rest area by the illuminance simulation analysis. The evaluation of the energy saving, economic benefits, and environmental effects of solar lighting technologies for highway rest area was, respectively, made in detail. It was proved that the application of solar technology for green lighting of highway rest facilities not only could have considerable energy saving capacity and achieve high economic benefits, but also make great contributions to the reduction of environment pollution.

  2. Replacing leads by self-energies using non-equilibrium Green's functions

    Michael, Fredrick; Johnson, M.D.

    2003-01-01

    Open quantum systems consist of semi-infinite leads which transport electrons to and from the device of interest. We show here that within the non-equilibrium Green's function technique for continuum systems, the leads can be replaced by simple c-number self-energies. Our starting point is an approach for continuum systems developed by Feuchtwang. The reformulation developed here is simpler to understand and carry out than the somewhat unwieldly manipulations typical in the Feuchtwang method. The self-energies turn out to have a limited variability: the retarded self-energy Σ r depends on the arbitrary choice of internal boundary conditions, but the non-equilibrium self-energy or scattering function Σ which determines transport is invariant for a broad class of boundary conditions. Expressed in terms of these self-energies, continuum non-equilibrium transport calculations take a particularly simple form similar to that developed for discrete systems

  6. The promotional impacts of green power products on renewable energy sources: direct and indirect eco-effects

    International Nuclear Information System (INIS)

    Markard, Jochen; Truffer, Bernhard

    2006-01-01

    Green power products may be seen as a means of fostering renewable energy sources because they create and channel consumer demand for environmentally sound power generation. They can therefore be evaluated on a par with other support instruments regarding their effectiveness to connect new capacity to the grid. Apart from this direct effect however, green power products confer a much more active role for customers and utilities. Thus, learning processes, which foster eco-oriented decisions beyond the construction of new renewable generation capacity, may be induced. In the present paper, we provide an encompassing review of the ecological consequences of green electricity products. We examine the direct eco-effects by comparing five European countries in their endeavor to increase electricity generation from renewable energy. The results show that the impact of green power on increasing renewable generation capacity is rather limited. In a second step, we analyze the contribution of green power in stimulating eco-oriented learning. It turns out that green power has particular potential in facilitating simultaneous learning processes involving power producers, traders, suppliers and consumers. We conclude that green electricity can be a crucial complement to governmental energy policies in the mid term. A precondition for reaping this potential is the careful policy design to create synergies in the interaction of regulatory support schemes and the green power market

  7. EH-GC: An Efficient and Secure Architecture of Energy Harvesting Green Cloud Infrastructure

    Directory of Open Access Journals (Sweden)

    Saurabh Singh

    2017-04-01

    Full Text Available Nowadays, the high power consumption of data centers is the biggest challenge to making cloud computing greener. Many researchers are still seeking effective solutions to reduce or harvest the energy produced at data centers. To address this challenge, we propose a green cloud infrastructure which provides security and efficiency based on energy harvesting (EH-GC. The EH-GC is basically focused on harvesting the heat energy produced by data centers in the Infrastructure-as-a-Service (IaaS infrastructure. A pyroelectric material is used to generate the electric current from heat using the Olsen cycle. In order to achieve efficient green cloud computing, the architecture utilizes a genetic algorithm for proper virtual machine allocation, taking into consideration less Service Level Agreement (SLA violations. The architecture utilizes Multivariate Correlation Analysis (MCA correlation analysis based on a triangular map area generation to detect Denial of Service (DoS attacks in the data center layer of the IaaS. Finally, the experimental analysis is explained based on the energy parameter, which proves that our model is efficient and secure, and that it efficiently reuses the energy emitted from the data center.

  8. National Low-Carbon Strategy. France in action. The energy transition for green growth

    International Nuclear Information System (INIS)

    2016-01-01

    The National Low-Carbon Strategy (SNBC), introduced by the energy transition for green growth act, outlines the approach to be adopted in order to reduce greenhouse gas emissions. It sets in motion the transition to a low-carbon economy. France, with its energy transition act for green growth, has committed to reduce its greenhouse gas emissions by 40% between 1990 and 2030 and fourfold between 1990 and 2050. France's greenhouse gas emissions per person are already among the lowest in the developed world, but more needs to be done. The act introduces tools designed to promote a low-carbon economy, namely 'carbon budgets' and the National Low-Carbon Strategy (SNBC), in order to achieve these new goals. These have been set for the 2015-2018, 2019-2023 and 2024-2028 periods. 'Carbon budgets' are caps on greenhouse gas emissions established for successive five-year periods, designed to set the downward trend in emissions. They are broken down into major sectors of activity (transport, housing, industry, agriculture, energy and waste). The SNBC outlines strategic guidelines for implementing the transition to a sustainable, low-carbon economy across all sectors of activity. It has been jointly developed with civil society by means of a broad public consultation and the close involvement of the National Council for Ecological Transition (CNTE). The SNBC comprises a series of overarching and sector-specific recommendations that outline the pathway to a low-carbon economy that will improve well-being, growth and employment. It sets a target for reducing the national carbon footprint, which remained stable between 1990 and 2012 owing to an increase in emissions linked to imports. It is important that we work together to ensure that we are not simply out-sourcing our emissions but actually reducing them. It will help raise both public and private funding for the energy transition. An 'energy transition for climate' label will help identify investment funds that are funding

  9. Willingness to pay for renewable energy: implications for UK green tariff offerings

    2000-01-01

    Although financial support for renewable electricity sources has existed via the non-fossil fuel obligation since 1990, the UK 'green power' market is still in its infancy. This paper looks at attitudes to tariffs for 'green power' in light of the proposed phase-out of the non-fossil fuel obligation. The hypothesis tested was the consumer's willingness to pay for electricity generated from renewable energy sources and to see if this was related to income and attitude. Data for analysis were taken from replies to a questionnaire sent to an energy-aware subpopulation of Leicester which were analysed by a variety of statistical tests. Results of multiple regression analysis indicated that whether someone was willing to pay more was significantly correlated with attitude, experience (whether they had visited an environmental centre) and the purchasing power placed on GBP 5.00. This finding has implications for the methods by which support for green tariffs can be increased. Education and raising people's awareness through experience should be able to change attitudes and so increase their willingness to pay. (author)

    2013-07-01

    In this paper, the joint operation of cooperative device-to-device (D2D) communications and green cellular communications is investigated. An efficient approach for grouping mobile terminals (MTs) into cooperative clusters is described. In each cluster, MTs cooperate via D2D communications to share content of common interest. Furthermore, an energy-efficient technique for putting BSs in sleep mode in an LTE cellular network is presented. Finally, both methods are combined in order to ensure green communications for both the users\\' MTs and the operator\\'s BSs. The studied methods are investigated in the framework of OFDMA-based state-of-the-art LTE cellular networks, while taking into account intercell interference and resource allocation. © 2013 IEEE.

  12. Integrating Variable Renewable Energy into the Grid: Key Issues, Greening the Grid (Spanish Version)

    Energy Technology Data Exchange (ETDEWEB)

    2016-04-01

    This is the Spanish version of 'Greening the Grid - Integrating Variable Renewable Energy into the Grid: Key Issues'. To foster sustainable, low-emission development, many countries are establishing ambitious renewable energy targets for their electricity supply. Because solar and wind tend to be more variable and uncertain than conventional sources, meeting these targets will involve changes to power system planning and operations. Grid integration is the practice of developing efficient ways to deliver variable renewable energy (VRE) to the grid. Good integration methods maximize the cost-effectiveness of incorporating VRE into the power system while maintaining or increasing system stability and reliability. When considering grid integration, policy makers, regulators, and system operators consider a variety of issues, which can be organized into four broad topics: New Renewable Energy Generation, New Transmission, Increased System Flexibility, and Planning for a High RE Future.

  13. General Retarded Contact Self-energies in and beyond the Non-equilibrium Green's Functions Method

    Science.gov (United States)

    Kubis, Tillmann; He, Yu; Andrawis, Robert; Klimeck, Gerhard

    2016-03-01

    Retarded contact self-energies in the framework of nonequilibrium Green's functions allow to model the impact of lead structures on the device without explicitly including the leads in the actual device calculation. Most of the contact self-energy algorithms are limited to homogeneous or periodic, semi-infinite lead structures. In this work, the complex absorbing potential method is extended to solve retarded contact self-energies for arbitrary lead structures, including irregular and randomly disordered leads. This method is verified for regular leads against common approaches and on physically equivalent, but numerically different irregular leads. Transmission results on randomly alloyed In0.5Ga0.5As structures show the importance of disorder in the leads. The concept of retarded contact self-energies is expanded to model passivation of atomically resolved surfaces without explicitly increasing the device's Hamiltonian.

    2018-04-17

    Aimed at a low-energy consumption of Green Internet of Things (IoT), this paper presents an energy-efficient compressive image coding scheme, which provides compressive encoder and real-time decoder according to Compressive Sensing (CS) theory. The compressive encoder adaptively measures each image block based on the block-based gradient field, which models the distribution of block sparse degree, and the real-time decoder linearly reconstructs each image block through a projection matrix, which is learned by Minimum Mean Square Error (MMSE) criterion. Both the encoder and decoder have a low computational complexity, so that they only consume a small amount of energy. Experimental results show that the proposed scheme not only has a low encoding and decoding complexity when compared with traditional methods, but it also provides good objective and subjective reconstruction qualities. In particular, it presents better time-distortion performance than JPEG. Therefore, the proposed compressive image coding is a potential energy-efficient scheme for Green IoT.

    2015-09-01

    Motivating individuals to choose energy from sustainable sources over conventionally produced power constitutes one of the biggest policy challenges for societies. Here we present the results of a randomized controlled trial in Germany that tested the impact of default rules (that is, a type of `nudging’) on voluntary purchases of `green’ energy contracts that entirely stem from renewable resources. Setting the default choice to more expensive `green’ energy (that is, where consumers have to actively opt out if they do not want it) increased purchases of such nearly tenfold. Furthermore, county-level political preference for the green party uniquely predicted behaviour in the absence of the nudge, suggesting that default setting potentially overrules motivational aspects of green energy purchases. In follow-up experiments, we provide further evidence that the effect does not seem to be driven by unawareness. Summarizing, the present research provides an example of using behavioural science for climate change mitigation and shows alternatives to the use of subsidies or other economic incentives.

    2013-01-01

    High technology and environment applications of the Rare Earth Elements (REE) have grown dramatically in diversity and importance over the past few decades. The REE forms largest economical coherent group in the periodic table. The versatility and specialty of the REE has given them a level of technological, environment and economical importance. As technological applications of REE have multiplied over the past several decades, the demand for them has increased dramatically. The green energy is the segment, which is largely contributed in its performance by the REE. The increasing concern about the impact of green house gases around the globe has made countries to explore clean energy technologies to reduce emissions. India has ambitious plans for generating solar power of 30,000 MW and wind energy of 50,000 MW by 2013. Critical component with respect to wind energy is the high strength rare earth permanent magnet, while in hybrid electrical motors REEs like lanthanum are used in LiMH battery pack

    2017-04-01

    Green Roofs have the potential to provide multiple services in cities. Besides acting as carbon sinks, providing noise reduction and decreasing air pollution - without requiring any additional "land-use" in a city (only roof-use), green roofs have a quantifiable potential to reduce direct and indirect energy and water use. They enhance the insulating capacity of a conventional residential roof and thereby decrease both cooling demands in summer and heating demands in winter. The former is further mitigated by the cooling effect of evapotranspiration from the roofs In New York City green roofs are additionally a valuable component of reducing "combined sewer overflows", as these roofs can retain storm water. This can improve water quality in the city's rivers as well as decrease the total volume of water treated in the city's wastewater treatment plants, thereby indirectly reduce energy demands. The impacts of green roofs on NYC's water-energy nexus has been initially studied (Engström et. al, forthcoming). The present study expands that work to more comprehensively investigate the potential of this type of nature-based solution in a dense city. By employing Geographical Information Systems analysis, the roof top area of New York City is analysed and roof space suitable for green roofs of varying types (ranging from extensive to intensive) are mapped and quantified. The total green roof area is then connected with estimates of potential water-energy benefits (and costs) of each type of green roof. The results indicate where green roofs can be beneficially installed throughout the city, and quantifies the related impacts on both water and energy use. These outputs can provide policy makers with valuable support when facing investment decisions in green infrastructure, in a city where there is great interest for these types of nature-based solutions.

  19. Green signalling effects in the market for energy-efficient residential buildings

    International Nuclear Information System (INIS)

    Fuerst, Franz; Oikarinen, Elias; Harjunen, Oskari

    2016-01-01

    Highlights: • Energy efficiency (EE) levels are hypothesised to affect house transaction prices. • We estimate a hedonic model using Energy Performance Certificates from Finland. • A price premium is found for the most energy-efficient properties. • The empirical results are suggestive of a green signalling effect. • Demand for EE high performers appears to be segmented from lower tiers. - Abstract: Empirical evidence from recent studies suggests that the price premium on energy-efficient buildings is potentially higher than the pure capitalisation of energy savings but the empirical evidence on the size of the non-savings components is scant. This study aims to fill this research gap by investigating whether the mandatory energy efficiency ratings for residential properties imply benefits that go beyond energy savings. Using a sample of several thousand apartment transactions from Helsinki, Finland, we first test if higher ratings were significantly associated with higher prices. In addition to a large number of property and neighbourhood characteristics, this dataset contains information on building-level energy usage which allows us to distinguish between the cost savings effect of energy consumption and the value of more intangible factors associated with the energy label. The hedonic model yields a statistically significant 3.3% price premium for apartments in the top three energy-efficiency categories and 1.5% when a set of detailed neighbourhood characteristics are included. When maintenance costs containing energy usage costs are added, a robust and significant price premium of 1.3% persists whereas no differentiation is found for the medium and lower rating categories. These findings may be indicative of energy-efficient buildings having signalling value – and therefore an additional incentive to invest in such buildings – for ‘green’ consumers. However, a favourable energy rating did not appear to speed up the sales process in the

    2001-07-01

    For the benefit of the discussion on greening the Dutch tax system, The Netherlands Bureau for Economic Policy Analysis (CPB) has made an analysis of the economic and environmental effects of raising the energy tax in the Netherlands, the so called Regulating Energy Tax.This energy tax is introduced in 1996 and has been raised in the following years in order to encourage energy efficiency improvement and the production of renewable energy. Since the introduction and the raising of this energy tax is coupled with a reduction of the tax tariffs on labour and capital, the tax basis is shifted towards environment polluting factors.This tax shift is called 'greening the tax system'. Five variants for raising the energy tax are analysed. In two of these variants the existing tariffs are raised by maintaining the existing exemption for energy use above a certain level. In the other two variants this level is raised, meaning that a larger part of the total energy use is taxed.In addition to these 4 variants, CPB has formulated a variant in which taxes have to be paid for all energy use without any exemption. In the long run uniform marginal tariffs for all energy users is the most efficient variant. Measures to reduce emissions will then be taken by the firms and households where the marginal reduction costs are relatively low. In the medium run the environmental and macroeconomic effects are almost the same in all variants. Raising the energy tax will result in a reduction of the emissions of CO2 in 2020 by 2,5 -8,5 Mton. The explanation for this range is the existence of large uncertainties concerning the development of costs and non-financial bottlenecks in the field of renewable energy production. The macro-economic costs of all variants in 2020 will be less then 0,1% GDP. The differences in environmental and macro-economic effects in the medium run are too small and the uncertainties about these effects are too large to rank these variants according their cost

  1. A Green Energy Application in Energy Management Systems by an Artificial Intelligence-Based Solar Radiation Forecasting Model

    2018-04-01

    Full Text Available The photovoltaic (PV systems generate green energy from the sunlight without any pollution or noise. The PV systems are simple, convenient to install, and seldom malfunction. Unfortunately, the energy generated by PV systems depends on climatic conditions, location, and system design. The solar radiation forecasting is important to the smooth operation of PV systems. However, solar radiation detected by a pyranometer sensor is strongly nonlinear and highly unstable. The PV energy generation makes a considerable contribution to the smart grids via a large number of relatively small PV systems. In this paper, a high-precision deep convolutional neural network model (SolarNet is proposed to facilitate the solar radiation forecasting. The proposed model is verified by experiments. The experimental results demonstrate that SolarNet outperforms other benchmark models in forecasting accuracy as well as in predicting complex time series with a high degree of volatility and irregularity.

    Improving the anode configuration to enhance biocompatibility and accelerate electron shuttling is critical for efficient energy recovery in microbial fuel cells (MFCs). In this paper, green reduced graphene nanocomposite was successfully coated using layer-by-layer assembly technique onto carbon brush anode. The modified anode achieved a 3.2-fold higher power density of 33.7 W m -3 at a current density of 69.4 A m -3 with a 75% shorter start period. As revealed in the characterization, the green synthesized nanocomposite film affords larger surface roughness for microbial colonization. Besides, gold nanoparticles, which anchored on graphene sheets, promise the relatively high electroactive sites and facilitate electron transfer from electricigens to the anode. The reduction-oxidation peaks in cyclic voltammograms indicated the mechanism of surface cytochromes facilitated current generation while the electrochemical impedance spectroscopy confirmed the enhanced electron transfer from surface cytochrome to electrode. The green synthesis process has the potential to generate a high performing anode in further applications of MFCs. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Green energy sources or renewable energy system generally utilize modular approach in their design. This sort of power sources are generally in DC form or in single cases AC. Due to high fluctuation in the natural origin of this energy (wind & solar) source they are stored as DC. DC power however are difficult to transfer over long distances hence DC to AC converters and storage system are very important in green energy system design. In this work we have designed a novel multilevel DC to AC converter that takes into account the modular design of green energy systems. A power conversion efficiency of 99% with reduced total harmonic distortion (THD) was recorded from our simulated system design.

    The gradual depletion of energy resources makes it necessary to optimize their use and to reuse them. Although great advances have already been made in optimizing energy generation processes, many of these processes generate energy that inevitably gets wasted. A clear example of this are nuclear, thermal and carbon power plants, which lose a large amount of energy that could otherwise be used for different purposes, such as heating greenhouses. The role of GreenVMAS is to maintain the required temperature level in greenhouses by using the waste energy generated by power plants. It incorporates a case-based reasoning system, virtual organizations and algorithms for data analysis and for efficient interaction with sensors and actuators. The system is context aware and scalable as it incorporates an artificial neural network, this means that it can operate correctly even if the number and characteristics of the greenhouses participating in the case study change. The architecture was evaluated empirically and the results show that the user's energy bill is greatly reduced with the implemented system.

    2016-05-03

    Adopting a green building rating system (GBRSs) that strongly considers use of renewable energy can have important environmental consequences, particularly in developing countries. In this paper, we studied on-site renewable energy and GBRSs at the system level to explore potential benefits and challenges. While we have focused on GBRSs, the findings can offer additional insight for renewable incentives across sectors. An energy model was built for 25 sites to compute the potential solar and wind power production on-site and available within the building footprint and regional climate. A life-cycle approach and cost analysis were then completed to analyze the environmental and economic impacts. Environmental impacts of renewable energy varied dramatically between sites, in some cases, the environmental benefits were limited despite the significant economic burden of those renewable systems on-site and vice versa. Our recommendation for GBRSs, and broader policies and regulations, is to require buildings with higher environmental impacts to achieve higher levels of energy performance and on-site renewable energy utilization, instead of fixed percentages.

  12. Surface energy balance of an extensive green roof as quantified by full year eddy-covariance measurements.

    Science.gov (United States)

    Heusinger, Jannik; Weber, Stephan

    2017-01-15

    Green roofs are discussed as a promising type of green infrastructure to lower heat stress in cities. In order to enhance evaporative cooling, green roofs should ideally have similar Bowen ratio (β=sensible heat flux/latent heat flux) characteristics such as rural sites, especially during summer periods with high air temperatures. We use the eddy-covariance (EC) method to quantify the energy balance of an 8600m 2 extensive, non-irrigated green roof at the Berlin Brandenburg Airport, Germany over a full annual cycle. To understand the influence of water availability on green roof-atmosphere energy exchange, we studied dry and wet periods and looked into functional relationships between leaf area, volumetric water content (VWC) of the substrate, shortwave radiation and β. The surface energy balance was dominated by turbulent heat fluxes in comparison to conductive substrate heat fluxes. The Bowen ratio was slightly below unity on average but highly variable due to ambient meteorology and substrate water availability, i.e. β increased to 2 in the summer season. During dry periods mean daytime β was 3, which is comparable to typical values of urban instead of rural sites. In contrast, mean daytime β was 0.3 during wet periods. Following a summer wet period the green roof maximum daily evapotranspiration (ET) was 3.3mm, which is a threefold increase with respect to the mean summer ET. A multiple regression model indicated that the substrate VWC at the present site has to be >0.11m 3 m -3 during summer high insolation periods (>500Wm -2 ) in order to maintain favourable green roof energy partitioning, i.e. mid-day βurban green roofs can be significantly optimised by using sustainable irrigation approaches.

  14. Optical solar energy adaptations and radiative temperature control of green leaves and tree barks

    Energy Technology Data Exchange (ETDEWEB)

    Henrion, Wolfgang; Tributsch, Helmut [Department of Si-Photovoltaik and Solare Energetik, Hahn-Meitner-Institut Berlin, 14109 Berlin (Germany)

    2009-01-15

    Trees have adapted to keep leaves and barks cool in sunshine and can serve as interesting bionic model systems for radiative cooling. Silicon solar cells, on the other hand, loose up to one third of their energy efficiency due to heating in intensive sunshine. It is shown that green leaves minimize absorption of useful radiation and allow efficient infrared thermal emission. Since elevated temperatures are detrimental for tensile water flow in the Xylem tissue below barks, the optical properties of barks should also have evolved so as to avoid excessive heating. This was tested by performing optical studies with tree bark samples from representative trees. It was found that tree barks have optimized their reflection of incoming sunlight between 0.7 and 2 {mu}m. This is approximately the optical window in which solar light is transmitted and reflected by green vegetation. Simultaneously, the tree bark is highly absorbing and thus radiation emitting between 6 and 10 {mu}m. These two properties, mainly provided by tannins, create optimal conditions for radiative temperature control. In addition, tannins seem to have adopted a function as mediators for excitation energy towards photo-antioxidative activity for control of radiation damage. The results obtained are used to discuss challenges for future solar cell optimization. (author)

  15. Cascading biomethane energy systems for sustainable green gas production in a circular economy.

    Science.gov (United States)

    Wall, David M; McDonagh, Shane; Murphy, Jerry D

    2017-11-01

    Biomethane is a flexible energy vector that can be used as a renewable fuel for both the heat and transport sectors. Recent EU legislation encourages the production and use of advanced, third generation biofuels with improved sustainability for future energy systems. The integration of technologies such as anaerobic digestion, gasification, and power to gas, along with advanced feedstocks such as algae will be at the forefront in meeting future sustainability criteria and achieving a green gas supply for the gas grid. This paper explores the relevant pathways in which an integrated biomethane industry could potentially materialise and identifies and discusses the latest biotechnological advances in the production of renewable gas. Three scenarios of cascading biomethane systems are developed. Copyright © 2017 Elsevier Ltd. All rights reserved.

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

    International Nuclear Information System (INIS)

    Umbach, Frank

    2015-05-01

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

  19. gTBS: A green Task-Based Sensing for energy efficient Wireless Sensor Networks

    KAUST Repository

    Al-Halafi, Abdullah

    2016-09-08

    Wireless sensor networks (WSN) are widely used to sense and measure physical conditions for different purposes and within different regions. However due to the limited lifetime of the sensor\\'s energy source, many efforts are made to design energy efficient WSN. As a result, many techniques were presented in the literature such as power adaptation, sleep and wake-up, and scheduling in order to enhance WSN lifetime. These techniques where presented separately and shown to achieve some gain in terms of energy efficiency. In this paper, we present an energy efficient cross layer design for WSN that we named \\'green Task-Based Sensing\\' (gTBS) scheme. The gTBS design is a task based sensing scheme that not only prevents wasting power in unnecessary signaling, but also utilizes several techniques for achieving reliable and energy efficient WSN. The proposed gTBS combines the power adaptation with a sleep and wake-up technique that allows inactive nodes to sleep. Also, it adopts a gradient-oriented unicast approach to overcome the synchronization problem, minimize network traffic hurdles, and significantly reduce the overall power consumption of the network. We implement the gTBS on a testbed and we show that it reduces the power consumption by a factor of 20%-55% compared to traditional TBS. It also reduces the delay by 54%-145% and improves the delivery ratio by 24%-73%. © 2016 IEEE.

    The Greening of the Department of Energy Headquarters is a comprehensive, multi-year project designed to identify and implement specific actions DOE can take to save energy and money, improve the comfort and productivity of employees, and benefit the environment. It is part of the Administration`s overall effort to promote greening in all of the nation`s federal buildings. Present Clinton started the Greening of the White House in 1993, and similar efforts have been undertaken by the Department of Defense at the Pentagon, the National Park Service at the Presidio, and now the Department of Energy at the Forrestal and Germantown buildings. The Greening of the Department of Energy Headquarters, An Action Plan for Success (Action Plan), unveiled on April 22, 1996, outlined more than 80 action items for DOE`s Forrestal and Germantown buildings. The action items were designed to increase energy efficiency, improve resource management, improve air quality, reduce water use, reduce paper use, improve landscape management, improve maintenance and operational procedures, increase employee participation, and promote education and outreach. In the two years since the Action Plan was introduced, the Department of Energy has made major progress in implementing specific action items designed to target four major subject areas: (1) Energy Efficiency; (2) Resource Management; (3) Air, Water, Landscape, and (4) Human Factors. This report outlines the status of the recommendations of the Action Plan since they were introduced two years ago.

    Purpose: The purpose of the project was to retrofit the front end (pulp house) of a commercial kraft pulping mill to accommodate a mill green liquor (GL) impregna-tion/soak/exposure and accrue downstream physical and chemical benefits while prin-cipally reducing the energy footprint of the mill. A major player in the mill contrib-uting to excessive energy costs is the lime kiln. The project was intended to offload the energy (oil or natural gas) demands of the kiln by by-passing the causticization/slaking site in the recovery area and directly using green liquor as a pulping medium for wood. Scope: The project was run in two distinct, yet mutually compatible, phases: Phase 1 was the pre-commercial or laboratory phase in which NC State University and the Insti-tute of Paper Science and Technology (at the Georgia Institute of Technology) ran the pulping and associated experiments, while Phase 2 was the mill scale trial. The first tri-al was run at the now defunct Evergreen Pulp Mill in Samoa, CA and lead to a partial retrofit of the mill that was not completed because it went bankrupt and the work was no longer the low-hanging fruit on the tree for the new management. The second trial was run at the MeadWestvaco Pulp Mill in Evedale, TX which for all intents and pur-poses was a success. They were able to fully retrofit the mill, ran the trial, studied the pulp properties, and gave us conclusions.

    1997-06-01

    The study on the title subject is part of a new long-term outlook for the period 1990-2020, focusing on the environment, mobility, space (physical planning) and energy. The environmental, employment and economic impacts of two levy variants have been analyzed. The first is the so-called Regulating Energy Levy (REB, abbreviated in Dutch), and the second is the Environment-Based Tax Law (WBM, abbreviated in Dutch). Tax rebates to households and businesses are in the form of a lower income tax and lower employer contributions. It is concluded that it is possible to double existing energy levies or to triple them for small-scale consumers without large economic impacts, provided that (1) large-scale consumers are spared; (2) the levies are rebated totally or partly; and (3) levy and rebate will be accepted by the Dutch society

    This Green Paper is the response to an observable fact: Europe growing future energy dependence. Its aim is to initiate a debate on the security of energy supply, an issue that is still very much alive. Three main points emerge from the Green Paper: the European Union will become increasingly dependent on external energy sources; enlargement will not change the situation; based on current forecasts, dependence will reach 70 % in 2030; the European Union has very limited scope to influence energy supply conditions (it is essentially on the demand side that the EU can intervene, mainly by promoting energy saving in buildings and the transport sector); at present, the European Union is not in a position to respond to the challenge of climate change and to meet its commitments, notably under the Kyoto Protocol. In these circumstances, the Commission would like the debate on the future strategy to be structured around the following principal questions: 1. Can the European Union accept an increase in its dependence on external energy sources without compromising its security of supply and European competitiveness? 2. Does not Europe increasingly integrated internal market, where decisions taken in one country have an impact on the others, call for a consistent and coordinated policy at Community level? What should such a policy consist of and where should competition rules fit in? 3. Are tax and State aid policies in the energy sector an obstacle to competitiveness in the European Union or not? 4. In the framework of an ongoing dialogue with producer countries, what should supply and investment promotion agreements contain? Given the importance of a partnership with Russia in particular, how can stable quantities, prices and investments be guaranteed? 5.

  7. External Knowledge Sourcing and Green Innovation Growth with Environmental and Energy Regulations: Evidence from Manufacturing in China

    2017-02-01

    Full Text Available This paper adopts the slacks-based measure-directional distance function (SBM-DDF, 2009 method for deriving the “Green Innovation Growth” rates of 28 manufacturing industries in China. The results indicate that the overall level of green innovation growth in China’s manufacturing is relatively low, with a declining trend. The tradeoffs among energy, environment and economy are rather sharp, and the “Porter Effect (1995” (environmental regulation will promote green technology innovation is not currently realized quickly in manufacturing. These evaluations imply an unsustainable development model in China, with significant differences among industries. By using a dynamic panel threshold model and employing an industry-level panel dataset for 2008–2014, we show that external knowledge sourcing has a significant negative impact on green innovation growth but with different constraints on R&D levels among industries. With the strengthening of R&D levels, gradually surpassing “critical mass”, the negative role of external knowledge sourcing in driving this mechanism becomes smaller and smaller; it has a non-linear relationship with the “threshold effect”. Consequently, we provide insights into the relationship among energy consumption, environmental pollution and technology innovation, and show how the heterogeneity of the R&D threshold affects differences in external knowledge sourcing and green innovation growth. These insights lead to a better understanding of the driving force, realizing path and policy design for green innovation growth.

  8. Study of a conceptual nuclear energy center at Green River, Utah: licensing considerations

    Dowdle, M.; Russell, R.; Zillman, D.

    1982-04-01

    This report examines the laws governing the location of a 9-unit nuclear energy center (NEC) near Green River, Utah. The time frame being considered for development of the conceptual NEC is from 1995 to 2013. Accordingly, the report is forced to speculate about some aspects of the plant, its site and its construction. Most of the report examines existing legal requirements for constructing an NEC. Where pertinent, changes in the law are discussed that would affect an NEC that is to be licensed in one or two decades. In general, no insurmountable legal problems exist that would prevent an NEC from being licensed at the Green River location. Several legal requirements pose significant concerns and would have to be faced before an NEC could be built. Among the major legal constraints are radiation protection, regulatory approval of financing, access to water, and local zoning restrictions. Two other constraints that involve legal matters are the wisdom of standardization of the units and the responsibility of the NEC builder to correct socio-economic impacts on the local area

    Full Text Available This study was conducted to characterize carbon nanotube (CNT/water nanofluids (CNWNFs and to apply the nanofluids in a heat-dissipation system of dual green energy sources. CNTs were mixed with water in weight fractions of 0.125%, 0.25%, and 0.5% to produce nanofluids. The thermal conductivity, density, viscosity, and specific heat of the nanofluids were measured. An experimental platform consisting of a simulated dual energy source and a microchip controller was established to evaluate the heat-dissipation performance. Two indices, the heat dissipation enhancement ratio and specific heat dissipation enhancement ratio (SHDER, were defined and calculated. The CNWNFs with a CNT concentration of 0.125 wt.% were used because they exhibited the highest SHDER. The steady-state performance was evaluated at 2 flow rates, 11 hybrid flow ratios, and 3 heating ratios for a total power of 1000 W. The transient behavior of the energy sources at preset optimal temperatures was examined, and the CNWNFs exhibited average increases in stability and heat dissipation efficiency of 36.2% and 5%, respectively, compared with water. This nanofluid heat-dissipation system is expected to be integrated with real dual energy sources in the near future.

    A large project is underway at Alameda County's twenty-year old 45 ha 4,000-inmate Santa Rita Jail, about 70 km east of San Francisco. Often described as a green prison, it has a considerable installed base of distributed energy resources including a seven-year old 1.2 MW PV array, a four-year old 1 MW fuel cell with heat recovery, and efficiency investments. A current US$14 M expansion will add approximately 2 MW of NaS batteries, and undetermined wind capacity and a concentrating solar thermal system. This ongoing effort by a progressive local government with considerable Federal and State support provides some excellent lessons for the struggle to lower building carbon footprint. The Distributed Energy Resources Customer Adoption Model (DER-CAM) finds true optimal combinations of equipment and operating schedules for microgrids that minimize energy bills and/or carbon emissions without 2 of 12 significant searching or rules-of-thumb prioritization, such as"efficiency first then on-site generation." The results often recommend complex systems, and sensitivities show how policy changes will affect choices. This paper reports an analysis of the historic performance of the PV system and fuel cell, describes the complex optimization applied to the battery scheduling, and shows how results will affect the jail's operational costs, energy consumption, and carbon footprint. DER-CAM is used to assess the existing and proposed DER equipment in its ability to reduce tariff charges.

    Effective ways to integrate human life quality, environmental pollution mitigation and efficient waste management strategies are becoming a crisis challenge for sustainable urban development. The aims of this study are: (1) to evaluate and recommend an optimum Urban Green Space (UGS) area for the Bangkok Metropolitan Administration (BMA); and (2) to quantify potential renewable resources including electricity generation and potential nutrient recovery from generated ash. Green House Gases (GHGs) emissions from the management of Green Residues (GR) produced in a recommended UGS expansion are estimated and compared with those from the existing BMA waste management practice. Results obtained from this study indicate that an increase in UGS from its current 2.02% to 22.4% of the BMA urban area is recommended. This optimum value is primarily due to the area needed as living space for its population. At this scale, GR produced of about 334kt·y -1 may be used to generate electricity at the rate of 206GWh·y -1 by employing incineration technology. Additionally, instead of going to landfill, phosphorus (P) contained in the ash of 1077 t P·y -1 could be recovered to produce P fertilizer to be recycled for agricultural cultivation. Income earned from selling these products is found to offset all of the operational cost of the proposed GR management methodology itself plus 7% of the cost of BMA's Municipal Solid Waste (MSW) operations. About 70% of the current GHGs emission may be reduced based on incineration simulation. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Highlights: • Our input–output model allows estimating impacts of energy efficiency programs on GDP and employment in Switzerland. • We provide with a deeper insight into modeling of income impacts of energy savings with regard to input–output method. • Geneva case study demonstrates that energy efficiency programs can have positive macroeconomic impacts in Switzerland. • Our results help to understand how to enhance positive macroeconomic impacts of energy efficiency programs. • We provide policy recommendations for further development of energy efficiency programs. - Abstract: In order to enhance energy efficiency as a pillar of transition to a green energy economy it is important to understand whether and under which conditions energy efficiency programs could have positive economic and social impacts. There are a growing number of studies on macroeconomic impacts of energy efficiency programs for various countries and regions. However, in Switzerland only few evaluations have been performed. The present study evaluates the impacts on GDP and employment of Geneva’s energy efficiency program portfolio éco21 which is operated by the local utility. Two programs aiming for electricity savings in the residential sector are analyzed: Eco-sociales targets social housing and Communs d’immeubles focuses on common spaces in buildings. An input–output model is developed, based on the Swiss input–output table, program administrator data, Swiss, and European statistics. Both impacts of initial expenditure and energy cost savings are evaluated. We estimate and compare the impacts of the two programs and discuss factors that cause differences. Our results show that energy efficiency programs can have positive impacts on GDP and employment. According to our estimates, each Swiss Franc (CHF) spent within the energy efficiency program creates approximately 0.2 CHF of additional GDP compared to the reference case scenario. Net impacts on employment are

    Full Text Available Fuel cells are a technological alternative to produce green energy, however, high costs make fuel cell a non-profitable option. This paper analyses the impact of the Colombian government incentives in the profitability of fuel cells. The analysis is based on the total operation cost of the fuel cell in three representative applications: residential, office and building elevator. The economic viability of fuel cell generation in those cases is contrasted with classical solutions like diesel generators and standard grid to provide a reference framework. Such results enable to evaluate the effectiveness of the Colombian government incentives in promoting the use of fuel cells over other less environmental-friendly options such as diesel generators. Finally, new incentives are proposed by subsidies offered by other countries with higher fuel cell penetration into their electric market. All the analyses are supported in simulations performed with a mathematical model parameterized using the characteristics of commercial devices.

    The Solar 2 Green Energy, Arts and Education Center is an 8,000 sq.ft. demonstration project that will be constructed to Platinum LEED certification and will be the first carbon-neutral, net-zero energy use public building in New York City, giving it local and national appeal. Employing green building features and holistic engineering practices throughout its international award-winning design, Solar 2 will be powered by a 90kW photovoltaic (PV) array in conjunction with a geothermal heating and cooling system and a high efficient design that seeks to reduce the overall energy load of the building. Solar 2 will replace our current 500 sq.ft. prototype facility - known as Solar 1 - as the educational and cultural centerpiece of a five-block public greenway on the East River in Stuyvesant Cove Park, located along two acres of public riverfront on a newly reclaimed, former brownfield in lower Manhattan. Designed as a public-use complex for year-round environmental education exhibits and onsite activities for all ages and backgrounds, Solar 2 will demonstrate energy-efficiency technologies and sustainable environmental practices available now to all urban residents, eco-tourists, teachers, and students alike. Showcasing one of Solar 2's most striking design elements is the PV roof array with a cafe and river vistas for miles of New York City's skylines. Capping the building as a solar-powered landmark, and visible from the FDR Drive, the PV array is also designed to provide visitors below a view of the solar roof when standing outside, as well as directly underneath it. Recognized by an international jury of architects, civil engineers and urban designers by the Swiss-based Holcim Foundation, the Solar 2 design was awarded the prestigious Holcim North American 2008 Gold Award for Sustainable Construction for innovative, future-oriented and tangible sustainable construction projects, selected from more than 1900 entries.

    Our planet has been endowed with a host of natural mechanisms to keep the environment and climate in balance. Humans are now facing the need to restore this balance that has been upset in the past years because of a growing population and resource demands. To steer dependency away from freshwater crops and decrease environmental damage from humanity s fuel and energy demands, it is necessary to take advantage of the natural adaptive biomass resources that are already in place. Using methods of Green Planet Architecture, based on compilations of current research and procedures, could lead to new forms of energy and fueling as well as new sources for food and feed. Green Planet Architecture involves climatic adaptive biomass; geospatial intelligence; agri- and aqua-culture life cycles; and soil, wetland, and shoreline restoration. Plants such as Salicornia, seashore mallow, castor, mangroves, and perhaps Moringa can be modified (natural, model-assisted, or genetically modified) to thrive in salt-water and brackish water or otherwise not arable conditions, making them potentially new crops that will not displace traditional farming. These fueling sources also have potential to be used in other rapid-growth industries, such as the aviation industry, that have incentive to move towards more sustainable fuel supplies. This paper highlights an example of how synergistic development of biomass resources and geospatial intelligence high-performance computing capabilities can be focused to resolve potential drought-famine problems. These techniques, provide a basis for future e-science-based discovery (and access) through technology that can be expanded to support global societal applications.

    Full Text Available In this paper we report the use of triethylene glycol reduced graphene oxide (TRGO as an electrode material for non-aqueous energy storage devices such as supercapacitors and Li-ion batteries. TRGO based non–aqueous symmetric supercapacitor is constructed and shown to deliver maximum energy and power densities of 60.4 Wh kg–1 and 0.15 kW kg–1, respectively. More importantly, symmetric supercapacitor shows an extraordinary cycleability (5000 cycles with over 80% of capacitance retention. In addition, Li-storage properties of TRGO are also evaluated in half-cell configuration (Li/TRGO and shown to deliver a reversible capacity of ∼705 mAh g–1 with good cycleability at constant current density of 37 mA g–1. This result clearly suggests that green-synthesized graphene can be effectively used as a prospective electrode material for non-aqueous energy storage systems such as Li-ion batteries and supercapacitors.

    2016-06-01

    Full Text Available The book “Energy and Transport in Green Transitions – Perspectives on Ecomodernity” deals with the societally and scientifically crucial topic of energy and climate change mitigation. The book starts by setting high ambitions as the authors attempt “to go beyond both the extremism of the anti-capitalist critique and the radical enthusiasm of techno-economic positivism” in their exploration to find ways to resolve political, economic and technological entanglements “to boost a greener economy and culture”. It aims to so through a regional comparative study that looks at mature Western economies, the rapidly developing China, and the developing economies in sub-Saharan Africa. The authors present an excellent descriptive historical review for those interested in the broader picture of energy production and automobile sector in the regions addressed. However, in an attempt to cover as much ground as possible while assuring "maximum accessibility”, the authors' explanation of the dynamics of change involved is not conveyed in an analytically convincing manner.

    It is a common practice in aerospace and automobile industries to use double wall panels as fuselage skins or in window panels to improve acoustic insulation. However, the scientific community is yet to develop a reliable prediction method for a suitable vibro-acoustic model for sound transmission through a curved double-wall panel. In this quest, the present work tries to delve into the modeling of energy transmission through a double-wall curved panel. Subsequently the radiation of sound power into the free field from the curved panel in the low to mid frequency range is also studied. In the developed model to simulate a stiffened aircraft fuselage configuration, the outer wall is provided with longitudinal stiffeners. A modal expansion theory based on Green's theorem is implemented to model the energy transmission through an acoustically coupled double-wall curved panel. An elemental radiator approach is implemented to calculate the radiated energy from the curved surface in to the free field. The developed model is first validated with various numerical models available. It has been observed in the present study that the radius of curvature of the surface has a prominent effect on the behavior of radiated sound power into the free field. Effect of the thickness of the air gap between the two curved surfaces on the sound power radiation has also been noted.

    Even without high and volatile oil prices, which have led to a downgrading of the prospects of economic growth in Europe, there would be very good reasons for the European Union to make a strong push towards a re-invigorated programme promoting energy efficiency at all levels of European society. This green paper seeks to act as a catalyst, leading to a renewed energy efficiency initiative at all levels of European society - EU, national, regional and local. Furthermore, this Green Paper seeks to make a significant contribution, by way of example and leadership, to kick-start an international effort to contribute to addressing climatic change through energy efficiency. China presently uses more than five times as much energy as the EU to produce one unit of GDP, USA uses approximately 50% more than EU. With exploding energy demand, in particular in China and India, energy efficiency must be one of the key policies to try to reconcile, on the one hand, the increased energy needs of the developing world to power growth and improve living conditions and, on the other hand, combat global warming. This Green Paper, and the momentum created in following it up, should put the EU at the forefront of efforts to make energy efficiency a global priority. (BA)

  5. Hydrogen Gas from Serpentinite, Ophiolites and the Modern Ocean Floor as a Source of Green Energy

    Science.gov (United States)

    Coveney, R. M.

    2008-12-01

    Hydrogen gas is emitted by springs associated with serpentinites and extensive carbonate deposits in Oman, The Philippines, the USA and other continental locations. The hydrogen springs contain unusually alkaline fluids with pH values between 11 and 12.5. Other workers have described off-ridge submarine springs with comparably alkaline fluid compositions, serpentinite, abundant free hydrogen gas, and associated carbonate edifices such as Lost City on the Atlantis Massif 15 km west of the Mid-Atlantic Ridge (D.S. Kelley and associates, Science 2005). The association of hydrogen gas with ultramafites is a consistent one that has been attributed to a redox couple involving oxidation of divalent iron to the trivalent state during serpentinization, although other possibilities exist. Some of the hydrogen springs on land are widespread. For example in Oman dozens of alkaline springs (Neal and Stanger, EPSL 1983) can be found over thousands of sq km of outcropping ophiolite. While the deposits in Oman and the Philippines are well-known to much of the geochemical community, little interest seems to have been displayed toward either the ophiolitic occurrences or the submarine deposits for energy production. This may be a mistake as the showings because they could lead to an important source of green energy. Widespread skepticism currently exists about hydrogen as a primary energy source. It is commonly said that free hydrogen does not occur on earth and that it is therefore necessary to use other sources of energy to produce hydrogen, obviating the general environmental benefit. However the existence of numerous occurrences of hydrogen gas associated with ophiolites and submarine occurrences of hydrogen suggests the likelihood that natural hydrogen gas may be an important source of clean energy for modern society remaining to be tapped. Calculations in progress should establish whether or not this is likely to be the case.

    Full Text Available It is well known that the Gulf Cooperation Council (GCC of countries resides at or close to the top of the global table of CO2 emissions per capita and its economy relies heavily on its fossil fuels. This provides a context for green building programs that initially aim to create an understanding of emission pathways within the GCC and hence develop approaches to their reduction in the built environment. A set of criteria will allow specific analysis to be undertaken linked to the spatial dimensions of the sector under study. In this paper, approaches to modelling energy consumption and CO2 emissions are presented. As investment in the built environment continues, natural resources dwindle and the cost of energy increases, delivering low-energy buildings will become mandatory. In this study, a hybrid modelling approach (bottom-top & top-bottom is presented. Energy benchmarks are developed for different buildings’ uses and compared with international standards. The main goals are to establish design benchmarks and develop a modelling tool that contains specific information for all buildings types (existing and new, as well as planned and projected growths within the various city districts, then integrate this database within a geospatial information system that will allow us to answer a range of “what-if”-type questions about various intervention strategies, emissions savings, and acceptability of pre-defined course of actions in the city sector under consideration. The spatial carbon intensity may be adjusted over a certain period, (e.g., through local generation (microgeneration or due to an increasing proportion of lower carbon-energy in the generation mix and this can be related to the sector and city overall consumption.

    Highlights: ► Optimized fuzzy logic controller for a hybrid green power system is developed. ► PSO algorithm is used to optimize membership functions of controller. ► Optimized fuzzy logic controller results in lower O and M costs and LPSP. ► Optimization results in less variation of battery state of charge. - Abstract: The objective of this study is to develop an optimized fuzzy logic controller (FLC) for operating an autonomous hybrid green power system (HGPS) based on the particle swarm optimization (PSO) algorithm. An electrolyzer produces hydrogen from surplus energy generated by the wind turbine and photovoltaic array of HGPS for later use by a fuel cell. The PSO algorithm is used to optimize membership functions of the FLC. The FLC inputs are (a) net power flow and (b) batteries state of charge (SOC) and FLC output determines the time for hydrogen production or consumption. Actual data for weekly residential load, wind speed, ambient temperature, and solar irradiation are used for performance simulation and analysis of the HGPS examined. The weekly operation and maintenance (O and M) costs and the loss of power supply probability (LPSP) are considered in the optimization procedure. It is determined that FLC optimization results in (a) reduced fluctuations in batteries SOC which translates into longer life for batteries and the average SOC is increased by 6.18% and (b) less working hours for fuel cell, when the load is met by wind and PV. It is found that the optimized FLC results in lower O and M costs and LPSP by 57% and 33%, respectively, as compared to its un-optimized counterpart. In addition, a reduction of 18% in investment cost is achievable by optimal sizing and reducing the capacity of HGPS equipment.

    Highlights: • Water-containing ABE solution (W-ABE) in the diesel is a stable fuel blends. • W-ABE can enhance the energy efficiency of diesel engine and act as a green energy. • W-ABE can reduce the PM, NOx, and PAH emissions very significantly. • The W-ABE can be manufactured from waste bio-mass without competition with food. • The W-ABE can be produced without dehydration process and no surfactant addition. - Abstract: Acetone–Butanol–Ethanol (ABE) is considered a “green” energy resource because it emits less carbon than many other fuels and is produced from biomass that is non-edible. To simulate the use of ABE fermentation products without dehydration and no addition of surfactants, a series of water-containing ABE-diesel blends were investigated. By integrating the diesel engine generator (DEG) and diesel engine dynamometer (DED) results, it was found that a diesel emulsion with 20 vol.% ABE-solution and 0.5 vol.% water (ABE20W0.5) enhanced the brake thermal efficiencies (BTE) by 3.26–8.56%. In addition, the emissions of particulate matter (PM), nitrogen oxides (NOx), polycyclic aromatic hydrocarbons (PAHs), and the toxicity equivalency of PAHs (BaP eq ) were reduced by 5.82–61.6%, 3.69–16.4%, 0.699–31.1%, and 2.58–40.2%, respectively, when compared to regular diesel. These benefits resulted from micro-explosion mechanisms, which were caused by water-in-oil droplets, the greater ABE oxygen content, and the cooling effect that is caused by the high vaporization heat of water-containing ABE. Consequently, ABE20W0.5, which is produced by environmentally benign processes (without dehydration and no addition of surfactants), can be a good alternative to diesel because it can improve energy efficiency and reduce pollutant emissions

  1. Green Growth - an Illusion? Energy and Climate Risk: Rethinking our Developmental Models

    Dessus, B.

    2011-01-01

    The years go by and international conferences come and go, with their quota of cries of alarm and calls to action to counter climate change. But in reality few large-scale programmes have been launched anywhere in the world involving concrete action to bring down greenhouse gas emissions. As one who has campaigned for many years for policies of energy consumption control, Benjamin Dessus shows here that the energy challenge is as great as it has ever been in a world of expanding populations in which most peoples aspire to reach the developmental level of the northern countries, despite the fact that our climate probably cannot support such a state of affairs. He argues here against a certain number of common suppositions, such as the idea of focussing exclusively on CO 2 in the fight against global warming, the need for a continuous economic growth on the order of 2% per annum or excessive faith in market mechanisms to bring down greenhouse gas emissions. He also stresses the ambiguities of so-called 'green' growth and compares different energy conservation scenarios. In this way, he shows that, against a relatively dominant line of reasoning based largely on (at times near-utopian) technological solutions and the continuation of sustained economic growth, there are more effective paths based on individual/collective energy sobriety and a serious slowdown of economic growth in the most developed countries, if not indeed a total halt to that growth (though these are more ambitious in that they require a revolution in the behaviour of the most affluent peoples). He concludes by proposing some courses of action for implementing such a programme in a country like France, showing the extent to which modern modes of life are going to have to change and how urgent it now is to debate these matters, if such change is to be achieved without - excessive - pain.

    Full Text Available Many bibliographical studies have highlighted the positive effects of green roofs as technological solutions both for new and renovated buildings. The one-year experimental monitoring campaign conducted has investigated, in detail, some aspects related to the surface temperature variation induced by the presence of different types of vegetation compared to traditional finishing systems for flat roofs and their impact from an energy and environmental point of view. The results obtained underlined how an appropriate vegetative solution selection can contribute to a significant reduction of the external surface temperatures (10 °C–20 °C for I > 500 W/m2 and 0 °C–5 °C for I < 500 W/m2, regardless of the season compared to traditional flat roofs. During the winter season, the thermal gradients of the planted surface temperatures are close to zero compared to the floor, except under special improving conditions. This entails a significant reduction of the energy loads from summer air conditioning, and an almost conservative behavior with respect to that from winter heating consumption. The analysis of the inside growing medium temperatures returned a further interesting datum, too: the temperature gradient with respect to surface temperature (annual average 4 °C–9 °C is a function of solar radiation and involves the insulating contribution of the soil.

    Green Growth examines the impact of wind energy on jobs and the economy in the EU. The wind energy industry increased its contribution to the EU's gross domestic product (GDP) by 33% between 2007 and 2010. In 2010, the industry's growth was twice that of the EU's GDP overall, with the sector contributing 32 billion euro to an EU economy in slowdown. The sector created 30% more jobs from 2007 to 2010 to reach nearly 240,000, while EU unemployment rose by 9.6% . By 2020, there should be 520,000 jobs in the sector. The sector was a net exporter of 5.7 billion euro worth of goods and services in 2010. The sector avoided 5.71 billion euro of fuel costs in 2010. The sector invested 5% of its spending in R and D - three times more than the EU average. Wind turbine manufacturers commit around 10% of their total turnover to R and D.

    Hybrid quantum mechanics/molecular mechanics (QM/MM) is applied to the fluorinated green fluorescent protein (GFP) chromophore (DFHBDI) in its deprotonated form to understand the solvatochromic shifts in its vertical detachment energy (VDE) and vertical excitation energy (VEE). This variant of the GFP chromophore becomes fluorescent in an RNA environment and has a wide range of applications in biomedical and biochemical fields. From microsolvation studies, we benchmark (with respect to full QM) the accuracy of our QM/MM calculations with effective fragment potential (EFP) as the MM method of choice. We show that while the solvatochromic shift in the VEE is minimal (0.1 eV blue shift) and its polarization component is only 0.03 eV, the effect of the solvent on the VDE is quite large (3.85 eV). We also show by accurate calculations on the solvatochromic shift of the VDE that polarization accounts for ∼0.23 eV and therefore cannot be neglected. The effect of the counterions on the VDE of the deprotonated chromophore in solvation is studied in detail, and a charge-smearing scheme is suggested for charged chromophores.

    This document summarizes a conceptual study on the feasibility and practicality of developing a nuclear energy center (NEC) at a representative Western site. The site selected for this conceptual study, an area of about 50 square miles, is located 15 miles south of Green River, Utah. The conceptual NEC would consist of nine nuclear electric generating units, arranged on the site in three clusters of three reactors each (triads), separated by about 2 1/2 miles. Of the total electric output of 11,250 MWe that the NEC could produce, about 82% is assumed to be transmitted out of Utah to Colorado, New Mexico, Arizona, Nevada, and California. The technical engineering issues studied included geology and seismology, plant design, low-level radioactive waste disposal, transmission, and construction schedules and costs. Socioeconomic issues included were demographics, land use, community service needs, and fiscal impacts. Environmental considerations included terrestrial and aquatic ecology, visual impact, and secondary population impacts. Radiological issues were concerned with the safety and risks of an NEC and an on-site low-level waste facility. Institutional issues included methods of ownership, taxation, implications of energy export, and water allocation. The basic finding was that an NEC would be technically feasible, but a number of socioeconomic and institutional issues would require resolution before a Western regional NEC could be considered a viable power plant siting option.

    As newsroom staff around the world went about their day on 25 March 2015, hundreds of volunteers located in over 100 countries gathered to monitor their news media as part of the Fifth Global Media Monitoring Project (GMMP). The Global Media Monitoring Project (GMMP) is the world’s longest......-running and most extensive research on gender in the news media. It began in 1995 when volunteers in 71 countries around the world monitored women’s presence in their national radio, television and print news. The research revealed that only 17% of news subjects – the people who are interviewed or whom the news...... is about – were women. It found that gender parity was ‘a distant prospect in any region of the world. News [was] more often being presented by women but it [was] still rarely about women.

  8. Can Culture Act as an Enabler to Innovation? Exploring the Germany-Ontario Experience Regarding the Introduction of Green Energy

    Directory of Open Access Journals (Sweden)

    Bill Irwin

    2015-02-01

    Full Text Available This paper explores the role that societal culture may play in terms of acting as an inhibitor or enabler when creating conditions conducive to innovative enterprise. To further understanding of this concept, the paper's authors explore different cultural influences and traditions of the country of Germany and the Canadian province of Ontario against the backdrop of the introduction of a government green energy policy and how local business reacts to new opportunities forthcoming from this shift in policy direction. The authors contend that the current Ontario psyche has contributed to an overall cultural drag on innovative activities. They demonstrate that in no place is this cultural impact more evident than the apparent lack of home-grown innovative activity surrounding green energy entrepreneurship; where, in spite of progressive and favourable provincial government policy, continued manufacturing growth is led by offshore companies The Ontario experience is in sharp contrast to current and historical German activity, when it comes to local innovation and advances in green energy. While Germany officially enacted their green energy act at the turn of the last century, experts agree that the German tenure with going green is in fact 35 to 40 years in the making. Although it has been contended that unique historical conditions such as postwar reconstruction and the reunification of the former East and West Germany have been significant contributing factors to Germany's embracing of sustainable energy, the authors of this paper contend that cultural factors such as the German sense of naturfreund; an overwhelming sense of being a nature-lover, may also play a significant role. In their exploration the authors build upon Hofstede's cultural dimension theory unpacking specific cultural components, as they compare actions and responses made by German and Ontarian policy-makers and business decision-makers.

  9. Market power in interactive environmental and energy markets: the case of green certificates

    Markets for environmental externalities are typically closely related to the markets causing such externalities, whereupon strategic interaction may result. Along these lines, the market for Green Certificates is strongly interwoven in the electricity market as the producers of green electricity are also the suppliers of Green Certificates. In this paper, we formulate an analytic equilibrium model for simultaneously functioning electricity and Green Certificate markets, and focus on the role of market power. We consider two versions of a Nash-Cournot game: a standard Nash-Cournot game where the players treat the market for Green Certificates and the electricity market as separate markets; and a Nash-Cournot game with endogenous treatment of the interaction between the electricity and Green Certificate markets with conjectured price responses. One result is that a certificate system faced with market power may collapse into a system of per unit subsidies, as the producers involved start to game on the joint functioning of markets.

    Small-and-medium-sized enterprises (SMEs) are significant to China's emission reduction programme. This research aims to improve our understanding of the challenge of diffusing green-manufacturing technologies among SMEs in China. Specifically, this study examines the Chinese Government's effort to facilitate reduction of energy consumption among SMEs through Energy Performance Contracts (EPCs) to incentivize domestic manufacturers to adopt energy efficient measures (EEMs) in order to reduce demand for energy and corresponding drop in emissions. The data is gathered from relevant EPC stakeholders in the National Motor Upgrading Demonstration Project and its implementation in Dongguan city, which is based on 30 in-depth interviews and 6 focus group discussions. Using stakeholder analysis, this study finds that guaranteed energy savings model is the favorite model in implementation, given the gained benefits outweigh committed resources, and the control capability overrides possible risks among the two core stakeholders. The outcomes of this study may allow the government to have a clear understanding of stakeholder perception of the different EPC models used in China so the design and deployment of these mechanisms can be improved. - Highlights: • Examine the barriers faced by green technologies when they are promoted to SMEs on a large scale. • Explain why green technology diffusion is thwarted when stakeholders cannot reach compromises. • Find that the guaranteed energy savings model is the best mechanism for upgrading SMEs. • Note that new EPC models and new policies are needed to increase stakeholders’ adoption rate.

    . In this paper we explore the apparent paradox in a quantitative analysis of information diffusion on Twitter. Twitter is interesting in this context as it has been shown to present both the characteristics social and news media. The basic measure of virality in Twitter is the probability of retweet. Twitter...... is different from email in that retweeting does not depend on pre-existing social relations, but often occur among strangers, thus in this respect Twitter may be more similar to traditional news media. We therefore hypothesize that negative news content is more likely to be retweeted, while for non-news tweets...

    The development of green building has been growing in both design and quality. The development of green building was limited by the issue of expensive investment. Actually, green building can reduce the energy usage inside the building especially in utilization of cooling system. External load plays major role in reducing the usage of cooling system. External load is affected by type of wall sheathing, glass and roof. The proper selection of wall, type of glass and roof material are very important to reduce external load. Hence, the optimization of energy efficiency and conservation in green building design is required. Since this optimization consist of integer and non-linear equations, this problem falls into Mixed-Integer-Non-Linear-Programming (MINLP) that required global optimization technique such as stochastic optimization algorithms. In this paper the optimized variables i.e. type of glass and roof were chosen using Duelist, Killer-Whale and Rain-Water Algorithms to obtain the optimum energy and considering the minimal investment. The optimization results exhibited the single glass Planibel-G with the 3.2 mm thickness and glass wool insulation provided maximum ROI of 36.8486%, EUI reduction of 54 kWh/m2·year, CO2 emission reduction of 486.8971 tons/year and reduce investment of 4,078,905,465 IDR.

    Highlights: ► A new methodology for improving energy system analysis models was proposed. ► The MARKAL model was integrated with the diffusion model. ► The new methodology was applied to green car technology. ► The ripple effect of green car technology on the energy system can be analyzed. -- Abstract: By 2020, Korea has set itself the challenging target of reducing nationwide greenhouse gas emissions by 30%, more than the BAU (Business as Usual) scenario, as the implementation goal required to achieve the new national development paradigm of green growth. To achieve such a target, it is necessary to diffuse innovative technologies with the capacity to drastically reduce greenhouse gas emissions. To that end, the ripple effect of diffusing innovative technologies on the energy and environment must be quantitatively analyzed using an energy system analysis model such as the MARKAL (Market Allocation) model. However, energy system analysis models based on an optimization methodology have certain limitations in that a technology with superior cost competitiveness dominates the whole market and non-cost factors cannot be considered. Therefore, this study proposes a new methodology for overcoming problems associated with the use of MARKAL models, by interfacing with a forecasting model based on the discrete-choice model. The new methodology was applied to green car technology to verify its usefulness and to study the ripple effects of green car technology on greenhouse gas reduction. The results of this study can be used as a reference when establishing a strategy for effectively reducing greenhouse gas emissions in the transportation sector, and could be of assistance to future studies using the energy system analysis model.

    International Nuclear Information System (INIS)

    1980-04-01

    The access to energy by the populations remains a primary preoccupation for the Government of Upper Volta (currently Burkina Faso). Due to this reason, a seminar on the utilization of renewable energy in rural area has been organized under the sponsorship of the Economic Community of West Africa (CEAO), the Canadian Agency of International Expansion and the Scout Movement. The goal of this seminar was to teach participants of several countries on how to put into practice the use of new sources of energy such as the cooker with closed fire, biological gas, the solar water-heater and the solar drier. The adoption of these new sources of energy by the populations would help mitigate problems of desertification caused by the intensive deforestation in the country. All the participants in this meeting are thus sensitized so that they will be able to positively contribute, along with their community, for a better conservation of the available natural resources. This can be done through the erection of closed fire cookers which can help get two sources of energy. This type of cooker is of easy construction and can be usable only three days after its construction. It helps avoid the loss of energy which has characterized the traditional way of cooking (around 95% of energy loss); this comes to rhyme with consuming less wood while ensuring an output of about 60 to 70%. It was question for the participants in this seminar to be initiated to the installation of gas by following Chinese and Indian models. They have been thus initiated to the realization of technologies of biological gas production throughout mastering the general diagram of the process of discontinuous fermentation. In the same way, they have acquired the know-how on the techniques of installation of the solar-fired heater by solar furnace and the solar drier. These tools help not only save energy but also the solar drier is a conservation tool which allows a bigger storage capacity of dry products and a

    Covalent organic frameworks (COFs), an emerging class of framework materials linked by covalent bonds, hold potential for various applications such as efficient electrocatalysts, photovoltaics, and sensors. To rationally design COF-based electrocatalysts for oxygen reduction and evolution reactions in fuel cells and metal-air batteries, activity descriptors, derived from orbital energy and bonding structures, are identified with the first-principle calculations for the COFs, which correlate COF structures with their catalytic activities. The calculations also predict that alkaline-earth metal-porphyrin COFs could catalyze the direct production of H 2 O 2 , a green oxidizer and an energy carrier. These predictions are supported by experimental data, and the design principles derived from the descriptors provide an approach for rational design of new electrocatalysts for both clean energy conversion and green oxidizer production. © 2017 WILEY-VCH Verlag GmbH & Co.

  19. Energy in the french and dutch Green plans: an instructive comparison

    1990-11-01

    In this article, while recognizing that the French Environment Plan has the merit of proposing, for the first time, an overview of the pollution problems to be tackled, the author however sets down a number of provisions in this regard. Through an examination of the three parts of the plan (the stakes and the findings, the goals, ways and means), he illustrates his point of view with the support of a detailed analysis of the proposals concerning energy. The comparison which he makes with the proposals contained in the Dutch Green Plan highlights the points which need to be reflected upon thoroughly in France. With relation to the rigor, the clarity, the accuracy, the seriousness of the assessments in the Dutch Plan, the author finds that the French Plan lacks a ranking of goals, a discussion of ways and means to be deployed, an adequate economic and financial framework, and it tends to prefer discourse to analysis and preconception to demonstration. This document is only an initial sketch; a real action plan still remains to be prepared.

    An extensive body of literature exists on the obstacles that have to be overcome in green power retailing. In this article, target group-specific marketing is evaluated as a strategy to increase the share of residential customers of green power. A sample of students in the city of Freiburg, Germany was interviewed in order to assess their awareness of environmental issues, their willingness to change to green power products, and to better understand individual hindrances in changing the power supplier. The analysis shows that students are highly positive towards green power products, but for several reasons difficult to reach in marketing campaigns. Aspects to be considered in addressing this consumer-group include the students' particular expectations towards green products, their living-conditions, price sensitivity, and their perception of the relative effort involved in changing the power provider.

    Development of supercapacitors with high energy density and long cycle life using sustainable materials for next-generation applications is of paramount importance. The ongoing challenge is to elevate the energy density of supercapacitors on par with batteries, while upholding the power and cyclability. In addition, attaining such superior performance with green and sustainable bio-mass derived compounds is very crucial to address the rising environmental concerns. Herein, we demonstrate the use of watermelon rind, a bio-waste from watermelons, towards high energy, and ultra-stable high temperature green supercapacitors with a high-voltage ionic liquid electrolyte. Supercapacitors assembled with ultra-high surface area, hierarchically porous carbon exhibits a remarkable performance both at room temperature and at high temperature (60 °C) with maximum energy densities of ∼174 Wh kg-1 (25 °C), and 177 Wh kg-1 (60 °C) - based on active mass of both electrodes. Furthermore, an ultra-high specific power of ∼20 kW kg-1 along with an ultra-stable cycling performance with 90% retention over 150,000 cycles has been achieved even at 60 °C, outperforming supercapacitors assembled with other carbon based materials. These results demonstrate the potential to develop high-performing, green energy storage devices using eco-friendly materials for next generation electric vehicles and other advanced energy storage systems.

    2011-02-01

    Full Text Available A content analysis of four Brazilian news media portals found that economic news dominated the top headlines with little attention paid to education, the environment and welfare. Other trends included a focus on local events and national news sources, reliance on few sources, mostly official ones, and a low percentage of news that fitted the concept of newsworthiness (a combination of both social significance and deviance concepts. Other findings of a study of 432 top news stories published by UOL, Estadão, iG and Terra during a 15-day period between February and March 2008 indicate that the top portions of the portals’ front pages carry news that lacks story depth, editorial branding, and multimedia applications. The results suggest that online news portals are in their infancy although Brazil has the largest online population of Latin America. This study hopes to shed light on the gatekeeping process in Brazilian news portals. Brazilian media portals have yet to become a significant editorial force able to provide knowledge about social issues and public affairs in a socially responsible fashione.

  4. Quota regime for renewable energy sources and Green Labels trading in the electricity market of the Netherlands

    International Nuclear Information System (INIS)

    Drillisch, J.

    1998-01-01

    The renewables quota regime combined with a ''green electricity'' labelling and trading system, implemented by the Dutch association of distribution undertakings, is the first of its kind in Europe. The distribution undertakings are bound by a commitment to take and distribute ''green label'' electricity from renewables amounting to approx. 3% of their total sales to contractual customers. This is a modest percentage, but the quota regime already proved to be a promoter of close-to-the-market generation technologies. It would be too early now to make a final statement on the quota regime's influence on enhanced use of renewable energy sources. Practice so far also revealed the need for some modifications in the design of the pricing system for''green electricity''. Current debates consider integration of renewable energy sources abroad. The first accounting date for giving evidence of compliance with the commitment to green label quotas is late in the year 2000. This will be the test for the system and the efficiency of sanctions provided for in case of non-compliance. It will be a task of the future to examine whether it might be appropriate to establish a similar system for the heat market. (RHM/CB) [de

  5. Framing hydropower as green energy: assessing drivers, risks and tensions in the Eastern Himalayas

    Ahlers, R.; Budds, J.; Joshi, D.; Merme, V.; Zwarteveen, M.

    2015-04-01

    The culturally and ecologically diverse region of the Eastern Himalayas is the target of ambitious hydropower development plans. Policy discourses at national and international levels position this development as synergistically positive: it combines the production of clean energy to fuel economic growth at regional and national levels with initiatives to lift poor mountain communities out of poverty. Different from hydropower development in the 20th century in which development agencies and banks were important players, contemporary initiatives importantly rely on the involvement of private actors, with a prominent role of the private finance sector. This implies that hydropower development is not only financially viable but also understood as highly profitable. This paper examines the new development of hydropower in the Eastern Himalayas of Nepal and India. It questions its framing as green energy, interrogates its links with climate change, and examines its potential for investment and capital accumulation. To do this, we also review the evidence on the extent to which its construction and operation may modify existing hydrogeological processes and ecosystems, as well as its impacts on the livelihoods of diverse groups of people that depend on these. The paper concludes that hydropower development in the region is characterized by inherent contentions and uncertainties, refuting the idea that dams constitute development projects whose impacts can be simply predicted, controlled and mitigated. Indeed, in a highly complex geological, ecological, cultural and political context that is widely regarded to be especially vulnerable to the effects of climate change, hydropower as a development strategy makes for a toxic cocktail.

    In this research we demonstrate that a flexible ultra-thin supercapacitor can be fabricated using high volume screen printing process. This has enabled the sequential deposition of current collector, electrode, electrolyte materials and adhesive onto a Polyethylene terephthalate (PET) substrate in order to form flexible electrodes for reliable energy storage applications. The electrodes were based on an activated carbon ink and gel electrolyte each of which were formulated for this application. Supercapacitors that have surface areas from 100 to 1600 mm"2 and an assembled device thickness of 375 μm were demonstrated. The capacitance ranged from 50 to 400 mF. Capacitance of printed carbon electrodes is rarely reported in literature and no references were found. The chemistry developed during this study displayed long-term cycling potential and demonstrated the stability of the capacitor for continued usage. The gel electrolyte developed within this work showed comparable performance to that of a liquid counterpart. This improvement resulted in the reduction in gel resistance from 90Ω to 0.5Ω. Significant reduction was observed for all resistances. The solid-state supercapacitors with the gel electrolyte showed comparable performance to the supercapacitors that used a liquid electrolyte. This large area printed device can be used in future houses for reliable green energy storage. - Highlights: • It has been demonstrated that a flexible supercapacitors with large area storage has been developed. • The simplified architecture has the potential to lead to a new class of printable, thin storage devices. • The specific capacitance of 21 F/g was measured.

    Eu 3+ doped alkali-barium-bismuth-tellurite (Eu 3+ :LKBBT) glasses were prepared by conventional melt quenching. Twelve emission bands including infrequent blue and green bands are observed and they almost cover whole visible spectral region under violet light radiation. The blue and green emissions of Eu 3+ rarely appeared in oxide glasses before, but they have been clearly recorded in Eu 3+ :LKBBT glasses even in the case of high concentration doping of Eu 3+ . The analysis based on spontaneous-radiative rate, energy gap and Raman scattering reveals that the obtaining of the abundant multichannel emissions of Eu 3+ is due to the higher refractive index and the lower phonon energy in LKBBT glass system

  13. A network approach to overcoming barriers to market engagement for SMEs in energy efficiency initiatives such as the Green Deal

    International Nuclear Information System (INIS)

    O’Keeffe, Juliette M.; Gilmour, Daniel; Simpson, Edward

    2016-01-01

    The Green Deal (GD) was launched in 2013 by the UK Government as a market-led scheme to encourage uptake of energy efficiency measures in the UK and create green sector jobs. The scheme closed in July 2015 after 30 months due to government concerns over low uptake and industry standards but additional factors potentially contributed to its failure such as poor scheme design and lack of understanding of the customer and supply chain journey. We explore the role of key delivery agents of GD services, specifically SMEs, and we use the LoCal-Net project as a case study to examine the use of networks to identify and reduce barriers to SME market engagement. We find that SMEs experienced multiple barriers to interaction with the GD such as lack of access to information, training, and confusion over delivery of the scheme but benefited from interaction with the network to access information, improve understanding of the scheme, increasing networking opportunities and forming new business models and partnerships to reduce risk. The importance of SMEs as delivery agents and their role in the design of market-led schemes such as the GD are discussed with recommendations for improving SME engagement in green sector initiatives. - Highlights: • The role of delivery agents should be addressed in voluntary energy reduction schemes. • SMEs attempting to engage in the Green Deal market faced multiple barriers. • Networks can assist in overcoming SME barriers to entry into new green sector markets. • Access to information, contacts and experts are key benefits of business networks. • Policy driven market-led schemes must consider all actors to prevent early failures.

    As one of the most concerned topics in strategic management research, the motivations of energy corporates’ green behaviours are extensively explored by scholars, however, only a few noticed the role of geographic antecedents. To bridge this gap, we argue that energy firms’ green behaviours will be greatly predicted by its location, more specifically, proximity to environmentally sensitive areas and central urban areas. Draw on neo-institutional theory and stakeholder theory, we argue that institutional forces mediate the links between energy corporates’ green behaviours and proximities, while different proximity affects via different institutional logics. The results are discussed along with managerial implications.

    A series of five new terbium(III) ion complexes with 4,4-difluoro-1-phenylbutane-1,3-dione (HDPBD) and anciliary ligands was synthesized. The composition and properties of complexes were analyzed by elemental analysis, IR, NMR, powder X-ray diffaraction, TG-DTG and photoluminescence spectroscopy. These complexes exhibited ligand sensitized green emission at 546 nm associated with 5 D 4  →  7 F 5 transitions of terbium ion in the emission spectra. The photoluminescence study manifested that the organic ligands act as antenna and facilitate the absorbed energy to emitting levels of Tb(III) ion efficiently. The enhanced luminescence intensity and decay time of ternary C2-C5 complexes observed due to synergistic effect of anciliary ligands. The CIE color coordinates of complexes came under the green region of chromaticity diagram. The mechanistic investigation of intramolecular energy transfer in the complexes was discussed in detail. These terbium(III) complexes can be thrivingly used as one of the green component in light emitting material and in display devices.

  20. Supporting renewable energy on liberalised markets: green electricity between additionally and consumer sovereignty

    International Nuclear Information System (INIS)

    Menges, R.

    2003-01-01

    The German feed-in regulation has been perhaps the most effective promotional policy for green electricity. However, with the growing momentum of the liberalisation process the current regulation is challenged by structural problems about how to address the demand side. Price regulation leaves little room for private green electricity market activities. Moreover, the success of the feed-in regulation depends on a strict differentiation of the political segment and the emerging green electricity markets. The question, therefore, is about the role green electricity markets can (or should) perform in general. In order to evaluate green electricity markets the additionality criteria is frequently used, implying that markets are only desirable if they lead to additional environmental effects. The additionality criteria has two implications: First, transformed into individual behaviour, additionality implies that consumers are assumed to act as pure altruists. However, there is evidence from empirical studies that green electricity consumers behave more as impure altruists: they are not so much interested in the objective environmental impact of their behaviour but more objected to receive a private satisfaction from buying an environmental friendly product. Whereas theoretical models in the case of pure altruism suggest that private activities crowd out totally when policy becomes active in supporting the public good, this crowding out disappears in the case of impure altruism. Second, using end-state criteria such as the additionality principle as precondition, and neglecting process criteria such as consumer sovereignty, means to prevent establishing competitive market process right at the outset in principle.

    Full Text Available In this article we investigate the impact of social media readership to the editorial profile of newspapers. We analyze tweets containing links to news articles from eight of the largest national newspapers in the United States, United Kingdom, Spain, Brazil, and Germany. The data collection follows the first two weeks of October 2012 and includes 2,842,699 tweets with links to news articles. Twitter-shortened links were resolved using a three-pass routine and assigned to 1 of the 21 newspaper sections. We found the concentration of links to news articles posted by top users to be lower than reported in the literature and the strategy of relaying headlines on Twitter via automatic news aggregators (feeds to be inefficient. The results of this investigation show which sections of a newspaper are the most and least read by readers in different parts of the world, with German readers placing greater emphasis on Politics and Economy; Brazilians on Sports and Arts; Spaniards on Local and National news; Britons and Americans on Opinion and World news. We also found that German and Spanish readers are more likely to read multiple national newspapers, while British readers more often resort to foreign sources of news. The results confirm that feedback to news items from a large user base is pivotal for the replication of content and that newspapers and news items can be clustered according to the editorial profile and principles of newsworthiness inherited from legacy media. The results of this investigation shed light onto the networked architecture of journalism that increasingly depends on readership agency.

    2017-12-01

    Full Text Available The pressing problems of climate change and energy insecurity can both, to a degree, be addressed by improving efficiency and conservation of energy use. A key driver of energy conservation is the consumer market, illustrating the important need to educate citizens towards adopting more sustainable practices. This form of education has several requirements: it must be cost-efficient, scalable, optional or non-intrusive, and self-motivating. We argue that one format that meets these requirements is serious social online games. We describe one such game, Green My Place, which was deployed in the context of the energy-efficiency promotion EU project SAVE ENERGY. We describe two studies evaluating the game, which showed limited positive effects. Analysing the results, we argue that although observable effects might be limited, the format bonuses such as low cost and scalability imply the value of serious social online games, given a large enough population.

    LaBSiO5 phosphors doped with Ce(3+) and Tb(3+) were synthesized using the conventional solid-state method at 1100 °C. The phase purity and luminescent properties of these phosphors are investigated. LaBSiO5:Tb(3+) phosphors show intense green emission, and LaBSiO5 phosphors doped with Ce(3+) show blue-violet emission under UV light excitation. LaBSiO5 phosphors co-doped with Ce(3+) and Tb(3+) exhibit blue-violet and green emission under excitation by UV light. The blue-violet emission is due to the 5d-4f transition of Ce(3+) and the green emission is ascribed to the (5) D4 → (7) F5 transition of Tb(3+). The spectral overlap between the excitation band of Tb(3+) and the emission band of Ce(3+) supports the occurrence of energy transfer from Ce(3+) to Tb(3+), and the energy transfer process was investigated.

    NASA's Energy and Water Cycle Study (NEWS) program fosters collaborative research towards improved quantification and prediction of water and energy cycle consequences of climate change. In order to measure change, it is first necessary to describe current conditions. The goal of the first phase of the NEWS Water and Energy Cycle Climatology project was to develop "state of the global water cycle" and "state of the global energy cycle" assessments based on data from modern ground and space based observing systems and data integrating models. The project was a multi-institutional collaboration with more than 20 active contributors. This presentation will describe the results of the water cycle component of the first phase of the project, which include seasonal (monthly) climatologies of water fluxes over land, ocean, and atmosphere at continental and ocean basin scales. The requirement of closure of the water budget (i.e., mass conservation) at various scales was exploited to constrain the flux estimates via an optimization approach that will also be described. Further, error assessments were included with the input datasets, and we examine these in relation to inferred uncertainty in the optimized flux estimates in order to gauge our current ability to close the water budget within an expected uncertainty range.

    2016-01-01

    Retarded contact self-energies in the framework of nonequilibrium Green's functions allow to model the impact of lead structures on the device without explicitly including the leads in the actual device calculation. Most of the contact self-energy algorithms are limited to homogeneous or periodic, semi-infinite lead structures. In this work, the complex absorbing potential method is extended to solve retarded contact self-energies for arbitrary lead structures, including irregular and randomly disordered leads. This method is verified for regular leads against common approaches and on physically equivalent, but numerically different irregular leads. Transmission results on randomly alloyed In 0.5 Ga 0.5 As structures show the importance of disorder in the leads. The concept of retarded contact self-energies is expanded to model passivation of atomically resolved surfaces without explicitly increasing the device's Hamiltonian. (paper)

  6. Is Germany's energy transition a case of successful green industrial policy? Contrasting wind and solar PV

    International Nuclear Information System (INIS)

    Pegels, Anna; Lütkenhorst, Wilfried

    2014-01-01

    In this paper, we address the challenge of Germany's energy transition (Energiewende) as the centrepiece of the country's green industrial policy. In addition to contributing to global climate change objectives, the Energiewende is intended to create a leading position for German industry in renewable energy technologies, boost innovative capabilities and create employment opportunities in future growth markets at the least possible cost. The success in reaching these aims, and indeed the future of the entire concept, is hotly debated. The paper aims to provide an up-to-date assessment of what has become a fierce controversy by comparing solar photovoltaic (PV) and wind energy along five policy objectives: (1) competitiveness, (2) innovation, (3) job creation, (4) climate change mitigation, and (5) cost. We find mixed evidence that Germany reaches its green industrial policy aims at reasonable costs. Wind energy seems to perform better against all policy objectives, while the solar PV sector has come under intense pressure from international competition. However, this is only a snapshot of current performance, and the long term and systemic perspective required for the energy sector transformation suggests a need for a balanced mix of a variety of clean energy sources. - Highlights: • We give an up-to-date assessment of costs and benefits of Germany's Energiewende. • We compare solar PV and wind to show key elements of policy success. • Considered policy objectives: competitiveness, innovation, jobs, emissions, costs. • Wind energy seems to perform better than solar PV against all policy objectives. • The results are a snapshot: a deep transformation requires energy diversification

    The effect of magnetic spin correlation on the thermodynamic properties of Heisenberg ferromagnetic single-walled nanotubes are comprehensively investigated by use of the double-time Green's function method. The influence of temperature, spin quantum number, diameter of the tube, anisotropy strength and external magnetic field to internal energy, free energy, and magnon specific heat are carefully calculated. Compared to the mean field approximation, the consideration of the magnetic correlation effect significantly improves the internal energy values at finite temperature, while it does not so near zero temperature, and this effect is related to the diameter of the tube, anisotropy strength, and spin quantum number. The magnetic correlation effect lowers the internal energy at finite temperature. As a natural consequence of the reduction of the internal energy, the specific heat is reduced, and the free energy is elevated. - Highlights: • Magnon specific heat and free energy of Heisenberg ferromagnetic single-walled nanotubes (HFM-SWNTs) are investigated. • The magnetic correlations effect has a considerable contribution to the thermodynamics properties of HFM-SWNTs. • Magnetic correlation effects are always to lower the internal energy at finite temperature. • At Curie point, magnetic correlation energy is much less than zero. • The peak values of magnon specific heat curves rise and shift right towards higher temperatures with the diameter of tubes, the anisotropy strength, and the spin quantum number rising.

    2011-03-15

    The purpose of the project is to select and validate technology concepts for the establishment of a Danish production of green synthetic fuels primarily for fuel cells. The feasibility of the selected concepts is assessed trough a techno-economical calculation, which includes mass and energy balances and economics including CAPEX and OPEX assessments. It is envisioned by the project partners that a production of green synthetic fuels, such as methanol, can 1) bring stability to a future electricity grid with a high share of renewable energy, 2) replace fossil fuels in the transport sector, and 3) boost Danish green technology export. In the project, two technology concepts were derived through carefully considerations and plenum discussions by the project group members: Concept 1): Methanol/DME Synthesis based on Electrolysis assisted Gasification of Wood. Concept 2): Methanol/DME synthesis based on biogas temporarily stored in the natural gas network. Concept 1) is clearly the most favored by the project group and is therefore analyzed for its techno-economic feasibility. Using mass and energy balances the technical perspectives of the concept were investigated, along with an economic breakdown of the CAPEX and OPEX cost of the methanol production plant. The plant was technically compared to a traditional methanol production plant using gasified biomass. The project group has decided to focus on large scale plants, as the scale economics favor large scale plants. Therefore, the dimensioning input of the concept 1) plant is 1000 tons wood per day. This is truly a large scale gasification plant; however, in a methanol synthesis context the plant is not particularly large. The SOEC electrolyzer unit is dimensioned by the need of hydrogen to balance the stoichiometric ratio of the methanol synthesis reaction, which will result in 141 MW installed SOEC. The resulting methanol output is 1,050 tons methanol per day. In comparison to a traditional methanol synthesis plant

    Xu, Yao; Leitner, David M

    2014-07-17

    We calculate communication maps for green fluorescent protein (GFP) to elucidate energy transfer pathways between the chromophore and other parts of the protein in the ground and excited state. The approach locates energy transport channels from the chromophore to remote regions of the protein via residues and water molecules that hydrogen bond to the chromophore. We calculate the thermal boundary conductance between GFP and water over a wide range of temperature and find that the interface between the protein and the cluster of water molecules in the β-barrel poses negligible resistance to thermal flow, consistent with facile vibrational energy transfer from the chromophore to the β-barrel waters observed in the communication maps.

    2011-01-01

    Studying the popularization of solar water heaters (SWHs) is significant for understanding China's transition to green energy systems. Using Dezhou as a case study, this paper presents new angles on analyzing SWH deployment in China by addressing both the economic potential and the institutional dimensions at the local level. Using estimates from the demand-side of hot water for a typical three-person household in Dezhou, the paper evaluates the economic potential of a SWH in saving electricity and reducing carbon dioxide emissions. Then, expanding the analysis beyond economics, we take an institutionalist approach to study the institutional factors that contribute to Dezhou's success in SWH adoptions. By examining the five main actors in Dezhou's energy regime, we find that Dezhou's SWH deployment is driven by an urge to develop businesses and the local economy, and its success results from at least five unique factors, including the development of SWH industrial clusters in Dezhou, big manufacturers' market leadership in SWH innovations, a tight private enterprise-local government relation, geographic location within the SWH industrial belt, and the adaptive attitude of Dezhou's households towards natural resource scarcity. - Highlights: → We study the popularization of solar water heaters in Dezhou, China. → We study the institutional factors that contribute to Dezhou's success. → Five main actors in Dezhou's energy regime are examined. → Dezhou's success results from at least five unique factors. → This leads to important directions for improving China'ss green innovation adoption.

    1987-01-01

    The Green's-function technique developed in the first paper in this series is generalized to apply to massive scalar, vector, second-order tensor, and Dirac spinor fields, as a preliminary to a full graviton calculation. The Casimir energies are of the form u/sub Casimir/ = (1/a 4 )[α/sub N/lna/b)+β/sub N/], where N (even) is the dimension of the internal sphere, a is its radius, and b/sup -1/ is an ultraviolet cutoff (presumably at the Planck scale). The coefficient of the divergent logarithm, α/sub N/, is unambiguously obtained for each field considered. The Green's-function technique gives rise to no difficulties in the evaluation of imaginary-mass-mode contributions to the Casimir energy. In addition, a new, simplified zeta-function technique is presented which is very easily implemented by symbolic programs, and which, of course, gives the same results. An error in a previous zeta-function calculation of the Casimir energy for even N is pointed out

    This document gathers pieces of news from the nuclear industry around the world. The most relevant are the following. EDF has inaugurated a logistic hub for the supply of spare parts for its 58 operating reactors. Russia has opened a new site to store spent fuels from RBMK reactors. This site is located at Zheleznogorsk near Krasnoiarsk in Siberia. The capacity of the La Hague fuel reprocessing plant is 1700 tonnes a year but the plant processes only between 800 and 1000 tones because most of its foreign contracts have come to an end and have not been renewed. In 2012 the plant is expected to process 1003 tonnes for EDF and 12 tonnes for The Netherlands. AREVA has delivered to the CNNC Chinese company 700 fuel assemblies and 800 control rod clusters. The French Institute for Radioprotection and Nuclear Safety (IRSN) said that there was neither health nor environmental hazards on French soil due to the Fukushima accident. The French Academy of Sciences has highlighted the least sanitary impact of nuclear power compared to other energies. The American Nuclear Safety Association has stated that the American nuclear power plants are safe and that the probability of a severe accident is very low. A new study shows an excess of cases of leukemia near nuclear power stations in France. This study rests on very few statistical cases. An opinion survey in the United Kingdom shows that the construction of nuclear power stations is considered as the best investment in infrastructures. EDF has planned to recruit in 2012 about 6000 people essentially in the nuclear sector. The Netherlands government has given its consent for the construction of the high flux reactor Pallas on the Petten site, this reactor will replace the HFR whose lifetime is over 50 years. (A.C.)

  4. How does Germany's green energy policy affect electricity market volatility? An application of conditional autoregressive range models

    Auer, Benjamin R.

    2016-01-01

    Based on a dynamic model for the high/low range of electricity prices, this article analyses the effects of Germany's green energy policy on the volatility of the electricity market. Using European Energy Exchange data from 2000 to 2015, we find rather high volatility in the years 2000–2009 but also that the weekly price range has significantly declined in the period following the year 2009. This period is characterised by active regulation under the Energy Industry Law (EnWG), the EU Emissions Trading Directive (ETD) and the Renewable Energy Law (EEG). In contrast to the preceding period, price jumps are smaller and less frequent (especially for day-time hours), implying that current policy measures are effective in promoting renewable energies while simultaneously upholding electricity market stability. This is because the regulations strive towards a more and more flexible and market-oriented structure which allows better integration of renewable energies and supports an efficient alignment of renewable electricity supply with demand. - Highlights: • We estimate a CARR model for German electricity price data. • We augment the model by dummies capturing important regulations. • We find a significant decline in the price range after the year 2009. • This implies effective price stabilisation by German energy policy.

    Full Text Available The last presidential elections in the United States of America (2016 have brought to the international public opinion’ s attention the phenomenon of “fake news”. Though it isn’t a new phenomenon, the spread of fake information for manipulating and misinforming the masses has existed in all historical periods. This time the phenomenon was noticed because of the number of fake news and, especially because of their impact, starting the discussion whether the victory of Donald Trump happened because of fake news and raising the question whether this phenomenon is a danger to democracy. An important reaction came also from the part of technology companies, of tech giants, Google and Facebook especially, which want the implementation of the phenomenon. Misinformation with public speech under the form of fake news brings to discussion the responsibility in the online space, but also the protection of people against this phenomenon.

    The project greenGain is looking for solutions to increase the energy production with regional and local biomass from landscape conservation and maintenance work, which is performed in the public interest. The relevant resources analysed in the greenGain model regions are, among others, biomass residues from clearing invasive vegetation in marginal agricultural lands in Spain, and residues from abandoned vineyards and olive groves in landscape protected areas in Italy. The main target groups are regional and local players who are responsible for maintenance and conservation work and for the biomass residue management in their regions. Moreover, the focus will be on service providers - including farmers and forest owners, their associations, NGOs, energy providers and consumers. Local companies, municipalities and public authorities are collaborating to identify the still underutilised non-food biomass resources and to discuss the way to integrate them into the local and regional biomass markets. Since the start of the three year project in January 2015, the partners from Italy, Spain, Czech Republic and Germany analysed, among other, the biomass feedstock potential coming from landscape maintenance work, and assessed various technological options to utilise this type of biomass. Further, political, legal and environmental aspects as well as awareness raising and public acceptance actions regarding the energetic use of biomass from public areas were assessed. greenGain also facilitates the exchange between model regions and other similar relevant players in the EU and shares examples of good practice. General guidelines will be prepared to guarantee a wide dissemination to other regions in the EU. Thus, the project shows how to build-up reliable knowledge on local availability of this feedstock and provides know-how concerning planning, harvesting, pre-treatment, storage and sustainable conversion pathways to a wide range of stakeholders in the EU.

    2014-08-11

    In this paper, the interplay between cooperative device-to-device (D2D) communications and green cellular communications in the long term evolution (LTE) and LTE-advanced (LTE-A) cellular systems is investigated. An efficient approach for grouping mobile terminals (MTs) into cooperative clusters is described. In each cluster, MTs cooperate via D2D communications to share content of common interest. In addition, an energy-efficient approach for putting base stations in sleep mode in an LTE-A heterogeneous network is presented. Finally, both methods are combined in order to ensure green communications for both the users\\' MTs and the operator\\'s base stations. The presented techniques are investigated in the framework of orthogonal frequency division multiple access-based state-of-the-art LTE cellular networks, while taking resource allocation and intercell interference into account. Results show that the proposed approach leads to energy savings for both the operator and the MTs, while leading to enhanced quality of service for mobile users.

    Highlights: • Open question if renewables achieve both environmental and socioeconomic objectives. • Two policies each assessed looking at energy access and employment respectively. • Important role of governments and need for monitoring capacity is confirmed. • Short-term socioeconomic benefits realized in two cases, but they may not sustain. • Cases underline need for methodologies to better assess multiple-objective policies. - Abstract: The Green Economy (GE) paradigm aims to reconcile environmental and socio-economic objectives. Policies to deploy renewable energy (RE) are widely perceived as a way to tap the potential synergies of these objectives. It is, however, still largely unclear whether the potential of simultaneously achieving both environmental and socio-economic objectives can be fully realized, and whether and how multiple objectives influence policy design, implementation, and evaluation. We aim to contribute to this aspect of GE research by looking at selected country experiences of renewable energy deployment with respect to the socio-economic goals of job creation or energy access. Across the cases examined, we find the following implications of relevance for the GE framework: First, we confirm the important role of governmental action for GE, with the specific need to state objectives clearly and build monitoring capacity. Second, consistent with the “strong” green growth variant of GE, some of the cases suggest that while renewable deployment may indeed lead to short-term socio-economic benefits, these benefits may not last. Third, we underline the urgent need for new methodologies to analyze and better understand multiple-objective policies, which are at the heart of the GE paradigm.

  17. Characterisation of chemical composition and energy content of green waste and municipal solid waste from Greater Brisbane, Australia.

    Hla, San Shwe; Roberts, Daniel

    2015-07-01

    The development and deployment of thermochemical waste-to-energy systems requires an understanding of the fundamental characteristics of waste streams. Despite Australia's growing interest in gasification of waste streams, no data are available on their thermochemical properties. This work presents, for the first time, a characterisation of green waste and municipal solid waste in terms of chemistry and energy content. The study took place in Brisbane, the capital city of Queensland. The municipal solid waste was hand-sorted and classified into ten groups, including non-combustibles. The chemical properties of the combustible portion of municipal solid waste were measured directly and compared with calculations made based on their weight ratios in the overall municipal solid waste. The results obtained from both methods were in good agreement. The moisture content of green waste ranged from 29% to 46%. This variability - and the tendency for soil material to contaminate the samples - was the main contributor to the variation of samples' energy content, which ranged between 7.8 and 10.7MJ/kg. The total moisture content of food wastes and garden wastes was as high as 70% and 60%, respectively, while the total moisture content of non-packaging plastics was as low as 2.2%. The overall energy content (lower heating value on a wet basis, LHVwb) of the municipal solid waste was 7.9MJ/kg, which is well above the World Bank-recommended value for utilisation in thermochemical conversion processes.

  8. Dedicating new real estate transfer taxes for energy efficiency: A revenue option for scaling up Green Retrofit Programs

    International Nuclear Information System (INIS)

    Lester, T. William

    2013-01-01

    As the labor market in the U.S. remains weak, with high unemployment and sluggish job growth, policymakers at various levels of government are looking for new ways to support job growth and investment during an increasingly tight fiscal climate. Policies that promote the “Green Economy” in general and energy efficiency in particular remain politically popular as potential win–win solutions that will create jobs and curb greenhouse gas emissions. Yet, efforts to promote energy efficiency in the residential sector through rebates and incentives alone have yet to reach critical mass. This paper outlines a policy option for state and local governments to use real estate transfer taxes to generate stronger incentives for home buyers to undertake significant retrofit projects at the time of sale. The economic impact of the proposed energy efficiency transfer tax (EETT) is then modeled for the State of North Carolina, using standard input–output techniques. Ultimately, based on housing sales figures from 2010, a new EETT of 2.5 percent on home purchases would generate a net positive increase of approximately 3485 direct construction jobs and 5900 annually total jobs for the state. -- Highlights: •Proposes an Energy Efficiency Transfer Tax (EETT) to catalyze residential retrofits. •Models household behavioral response to an EETT. •Estimates induced energy efficiency investment levels in North Carolina. •Calculates net employment impacts of a hypothetical EETT. •Finds net impact of 5900 jobs and over $350 million in additional investment

  15. Green energy - the road to a Danish energy system without fossil fuels. Summary of the work, results and recommendations of the Danish Commission on Climate Change Policy

    Energy Technology Data Exchange (ETDEWEB)

    2010-09-15

    This summary report describes the main outcomes of the deliberations of the Danish Commission on Climate Change Policy. It includes a proposal for how Denmark can become independent of fossil fuels and, at the same time, meet the target of reducing greenhouse gases by 80%-95% compared with 1990. In addition, 40 specific recommendations for initiatives which will contribute to the realisation of the vision are presented. The documentation section of the overall report, which is only available in Danish, presents the Climate Commission's work in more detail, as well as a description of the comprehensive analyses on which the Climate Commission has based its recommendations. Finally, the background documents, which have been prepared at the request of the Climate Commission are available (in Danish) at the Commission's website, www.klimakommissionen.dk. We can both reduce Danish emissions of greenhouse gasses significantly, and make Denmark independent of fossil fuels. This will require a total conversion of the Danish energy system; conversion away from oil, coal and gas, which today account for more than 80% of our energy consumption, and to green energy with wind turbines and bioenergy as the most important elements. The cost of conversion may seem surprisingly low. The low cost means that not only can we maintain our present living standards, we can also have considerable economic growth, so that energy expenditures will constitute less of our budgets in the future than today. The reason the cost is not higher is primarily because we will not have to pay for overpriced fossil fuels and CO{sub 2} reductions, and we will be able to limit our energy consumption through efficiency improvements in all areas in the future. It is difficult to make predictions about the exact design of the green energy system of the future. However, in overall terms it could look like this: 1) Energy will be used far more efficiently, so that we can, for example, heat our houses

    The Green Institute is an organization dedicated to improving the environment and creating employment opportunities in Minneapolis. This paper provided details of the institute's 2004 installation of a green roof system on the Phillips Eco-Enterprise Center, which was built by the institute in 1999. The building design included geo-exchange heating and cooling, an active day-lighting system, and an energy recovery ventilator. Structural support for a green roof was added during construction. While the rooftop structure was initially designed as an intensive green rooftop, the institute eventually decided to create an extensive green roof system combined with a deck area for visitors. The design of the green roof included a circular central gathering area with spokes. A mixture of sedums were planted, as well as plants native to Minnesota river bluff prairies. A variety of species were planted in order to determine which plant varieties would succeed. This paper provided technical details of the green roof's installation, as well as details of the organizational and administrative procedures required to orchestrate the different contractors and volunteers involved in the project. Details of the materials used for the construction of the roof were also included. The rooftop was opened to the public in 2005, and building tenants currently use the green roof for meetings, lunches and breaks. Television news stations have visited the roof, which is also visible to passengers on the Minneapolis light rail transit line. The Green Institute has continued to promote green roof market development in the city with a variety of green roof events, symposiums and workshops. The institute has also been successful in implementing a credit system to reduce stormwater utility fees for buildings with green roofs.

    Energy Technology Data Exchange (ETDEWEB)

    2011-02-15

    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)

    The multi-annual energy plan aims at completing the transition towards an energy system which is more efficient, less wasteful, more diverse and therefore more resilient. It reaffirms France's commitment to reducing energy consumption, particularly energy from fossil fuels. The future of France's energy sector lies in striking a harmonious balance between different energy sources. These strategic decisions will help to meet France's objectives to keep greenhouse gas emissions to a minimum in line with its commitments to the EU and to the Paris Climate Agreement, to protect human health and the environment and to ensure access to energy at a reasonable cost whilst stimulating economic activity and employment. This document is the multi-annual energy plan for the inhabited and non-interconnected Ponant Islands (Ouessant, Molene, Sein). It establishes the priority actions for all energy sources with respect to demand control, supply diversification, supply security, supply and demand management, renewal of production means. It covers a first 3-years period (2016-2018) followed by a second 5-years period (2019-2023)

    be considered and also modern regulatory approaches. Much attention is paid in this report to the modern market instruments, which are based on the concept of trading, with the most prominent representative being the European Emissions Trading scheme. Other more recent market based instruments discussed in this report are the White and Green Certificates. Encompassing the above, this report intends to provide an overview of all major P+M for energy efficiency improvement. The P+M are categorized according to some parameters such as a general description of the measure, the sector applied, the mechanism at work, the countries where this measure has been designed and/or implemented and the stakeholders they involve during their implementation. Furthermore, a critical assessment of each measure follows according to some criteria, like effectiveness, efficiency and goal achievement. The underlying motivation for the preparation of such an inventory of P+M is to establish the grounds for a comparative assessment of measures as they are currently discussed and/or applied in the European Union. Four P+M will then be chosen which will be then analyzed in depth in Phase II of the 'White and Green' project. In this phase simulation models will be used to study the impact of various solutions on the cost of saving energy (particularly electricity and gas), the role that different technologies could play and their expected diffusion, etc. In the context outlined above, it is clearly of interest to assess the various solutions for market-oriented policy measures aimed at increasing the efficiency in the final uses of energy, to identify the best practices and to present, to the European Commission and to the Member states, indications on the potential advantages of using such practices in the promotion of a common energy policy objective
