The demands to exploit the geological subsurface are increasing. In addition to the traditional production of raw materials such as natural gas and petroleum, or potable groundwater extraction the underground will most likely also be used to implement the climate and energy policy objectives in the context of the energy transition to renewables. These include the storage of energy from renewable sources (e.g. hydrogen and methane), the use of geothermal energy and possibly the long-term storage of carbon dioxide to reduce the release of greenhouse gases into the atmosphere. The presentation addresses the question which realistic contribution can be expected from the geo-resource subsurface for the energy revolution, the detachment of fossil and nuclear fuels as well as the reduction of CO2 emissions. The study of Henning and Palzer [1] that models the energy balance of the electricity and heat sector including all renewable energy converters, storage components and loads for a future German energy system shows that provision with 100% renewables is economically feasible by 2050. Based on their work, our estimates underline that already in 2015 more than 100% of the required methane storage capacities therein are available and more than 100% of the heat pump demands might be covered by shallow and deep geothermal energy production in the future. In addition we show that a newly developed energy storage system [2-3] could be applied to store 20-60% of the surplus energy from renewables expected for 2050 with integrated gas storage of methane and CO2.

Renewable energies are essential contributors to the energy supply portfolio as they contribute to world energy supply security, reducing dependency on fossil fuel resources, and provide opportunities for mitigating greenhouse gases. Differences in definition and lack of adequate data complicated the discussion between participants on these key issues. The International Energy Agency believes that this fact sheet can be of use to all to facilitate the debate on the past, current and future place and role of renewables in total energy supply. Our goal is to present as objectively as possible the main elements of the current renewables energy situation. The definitions and coverage of national statistics vary between countries and organisations. In this fact sheet, the renewables definition includes combustible renewables and waste (CRW), hydro, geothermal, solar, wind, tide and wave energy.

2017-08-01

Full Text Available Energy justice is increasingly being used as a framework to conceptualize the impacts of energy decision making in more holistic ways and to consider the social implications in terms of existing ethical values. Similarly, renewable energy technologies are increasingly being promoted for their environmental and social benefits. However, little work has been done to systematically examine the extent to which, in what ways and in what contexts, renewable energy technologies can contribute to achieving energy justice. This paper assesses the potential of renewable electricity technologies to address energy justice in various global contexts via a systematic review of existing studies analyzed in terms of the principles and dimensions of energy justice. Based on publications including peer reviewed academic literature, books, and in some cases reports by government or international organizations, we assess renewable electricity technologies in both grid integrated and off-grid use contexts. We conduct our investigation through the rubric of the affirmative and prohibitive principles of energy justice and in terms of its temporal, geographic, socio-political, economic, and technological dimensions. Renewable electricity technology development has and continue to have different impacts in different social contexts, and by considering the different impacts explicitly across global contexts, including differences between rural and urban contexts, this paper contributes to identifying and understanding how, in what ways, and in what particular conditions and circumstances renewable electricity technologies may correspond with or work to promote energy justice.

Full Text Available The MED Programme is part of the EU Regional Policy and operates in the framework of the European Territorial Cooperation objective. In 2014, the MED Programme approved 14 thematic projects specifically targeted on maritime context with two of them addressing marine renewable energy and renewable energy in coastal areas: Bluene and Enercoast. These projects aim at contributing to the deployment of marine renewable energy technologies in the Mediterranean by gathering data, developing mapping activities, identifying policy gaps and addressing other obstacles hindering transnational cooperation potential. The objective of this article is to analyse the delivered results and outputs of these projects against the identified challenges and roadmap defined by the European Commission. Results were evaluated under a transferability and continuation approach applied to the period 2014–2020. This article also identifies and suggests ways in which transnational cooperation would enhance obtained results towards a higher implementation of marine renewable energy in the Mediterranean.

While the share of renewable energy, especially wind power, increases in the energy mix, the risk of temporary energy shortage increases as well. Thus, it is important to understand consumers' preference for the renewable energy towards the continuous growing renewable energy society. We use a discrete choice experiment to infer consumers' preferences when the share of renewable energy increases. The study results indicate that consumers are generally willing to pay extra for an increasing share of renewable energy, but the renewable energy should come from a mixture of renewable energy sources. We also found that consumers prefer to trade with their current supplier rather than another well-known supplier. This study contributes to the energy portfolio theories and the theory of energy diversification in a consumer perspective. The managerial implications of this study are also discussed. - Highlights: • This paper investigates consumer preference for electricity when the share of renewable energy increases in the energy mix. • A total of 7084 choice sets were completed in the survey. • Consumer prefers a high percentage of mixed renewable energy at an affordable price level when the share of renewable increases. • Current electricity supplier was found to be the most favorable supplier for consumers. • Results had implications on energy regulators/policy makers, electricity retailers and renewable energy investors.

This article presents and discusses the results of an evaluation made by the so-called 'Swiss Energy Trialogue' ETS on the potential offered by new renewable energy sources in Switzerland. The evaluation forecasts an important contribution to Swiss energy supply by renewable energy sources by the year 2050. The authors are of the opinion that, in spite of a considerable increase in the offers of renewable energy and the full use of energy saving potential, a discrepancy will exist between estimates of energy needs and the actual energy available from renewable resources if large-scale power generation facilities are not built. Activities proposed by the Swiss government are discussed and analysed. In particular, possible contributions to be made by renewable energy sources are examined. Suggestions made by ETS concerning possible courses of action are discussed

National Renewable Energy Policy in a Global World

Science.gov (United States)

Jeong, Minji

Increasing trade of renewable energy products has significantly contributed to reducing the costs of renewable energy sources, but at the same time, it has generated protectionist policies, which may negatively affect the trend of the cost reduction. Although a few recent studies examined the rise of renewable energy protectionism and trade disputes, they are limited in addressing the conflict between the original goal of traditional renewable energy policies and the new protectionist policies under the globalized renewable energy industry. To fill this gap, this dissertation explores how the globalized renewable energy industry has changed national renewable energy policies. Through three analyses, three aspects of the globalized renewable energy industry are examined: the rise of multinational corporations, international interactions among actors, and the changes of the global and domestic market conditions. First analysis investigates how multinational renewable energy corporations have affected national policies. A content analysis of the annual reports of 15 solar photovoltaic multinational corporation shows that solar multinationals have been influenced by national policies and have adapted to the changes rather than having attempted to change national policies. Second analysis examines how diverse actors have framed renewable energy trade issues through a network analysis of the Chinese solar panel issue in the United States. The result shows that the Chinese solar panel issue was framed differently from the traditional environmental frame of renewable energy, being dominated by multinational corporations headquartered in other countries. Third analysis explores what has caused the increasing diversity in national renewable energy policies through the case studies of the U.S. and South Korea. The result reveals that the globalization of solar industry has affected the diversification of solar policies in two countries by generating both challenges, which

The future of marine renewable energies. Summary of the Ifremer Futures study on marine renewable energies to 2030

International Nuclear Information System (INIS)

Lacroix, D.; Paillard, M.

2008-01-01

The challenge posed by climate change and the predicted scarcity of fossil fuels is so great that energy questions are increasingly in the headlines. There has, in this context, been an increasing promotion of renewable energies, as is attested by France and the EU's stated objective of producing 20% of consumed energy from renewable sources by 2020. Among the different renewable energies, the ocean represents an immense reserve (tidal and tidal-stream energy, wave and wind power, marine biomass etc.) and a genuine asset for those countries like France which have the good fortune to have many seaboards (both at home and overseas). In order to gauge the potential of marine renewable energies, Ifremer began an enormous foresight exercise in March 2007 examining scenarios to the year 2030 in partnership with the main actors in the maritime world and with methodological support from Futuribles. Denis Lacroix and Michel Paillard, who were members of the steering committee of that study, present the broad outlines of this foresight exercise and the possible prospects for marine renewable energies. After reviewing the various forms of marine energy, they set out the methods followed and the range of possible scenarios selected, together with the potential of the different technologies associated with marine renewable energies. They then show the extent to which these energies could contribute to the French energy supply to 2030, before developing a ''normative'' scenario that can serve as a strategic axis for French energy policy so far as marine renewable energies are concerned (on the basis of a contribution of around 3% to the French energy mix in 2020).

2011-01-01

This paper is the summary of a conference day organised by the students of the 'environment and sustainable development law' Master of Nantes university (France). This interdisciplinary meeting brought together professionals of renewable energy industries who could testify about the resistance of both politicians and the public opinion against the energy transition towards renewable sources. Legal, political, sociological and cultural considerations are put forward to explain this resistance. The French specificity, with an over-representation of nuclear energy, a constraining legal framework for renewable energies, a regional opposition to renewable energy projects (NIMBY syndrome), and a lack of trust in the political class and in its representatives are as many factors that have contributed to build this French 'cultural exception'.

These two regions are presented separately in this volume and its sister publication. The country profiles combine elements of IRENA analysis with the latest information available from a vast array of sources in order to give a brief yet comprehensive and up-to-date picture of the situation of renewable energy that includes energy supply, electrical capacity, energy access, policies, targets, investment climate, projects and endowment in renewable energy resources. Because of the different timelines of these sources, data presented here refer to years between 2008 and 2012. Data availability also differs from country to country, which makes comparison with a wider regional group possible only for the year for which figures are available for all the members of the group; while this may not be the most recent year, the differences between countries, regions and the world remain striking. The current country profiles are just a starting point; they will be extended upon with new indicators to make them more informative, and maintained as a live product on the IRENA website as a key source of information on renewable energy.

Projected cost-performance data are used to calculate the Canadian commercial potential of selected renewable energy technologies to the year 2010. Based on projected market penetration, the extent to which renewable energy can contribute to environmental initiatives is also examined. The potential for renewable energy to contribute to the Canadian electricity supply is limited neither by the state of the technology nor the extent of the resource available. Barriers to acceptance of renewables include high initial capital costs, intermittent nature of much of the energy supply, land requirements, onerous requirements for environmental assessments and licensing, and lack of government policies which consider the externalities involved in new energy supply. Environmental benefits which will drive the adoption of renewables in Canada include the sustainable nature of renewable resources, low environmental impacts, and suitability for integrated resource planning. In addition, the cost performance of renewable technologies is improving rapidly. Under base-case scenarios, at current buyback rates, only small hydro and biomass of the five renewable technologies examined has significant commercial potential in Canada. At buyback rates that reflect currently projected avoided costs plus an additional 2 cents per kWh as an environmental premium, all five renewable technologies except for photovoltaics have appreciable commercial potential achievable by 2010. The quantity of electrical energy displaced under this latter scenario is estimated at 49 TWh/y, or 7% of the projected total generation in Canada. 2 figs., 2 tabs

Renewable energy policy in South Africa: policy options for renewable electricity

2005-01-01

Investment in renewable energy and energy efficiency is important to reduce the negative economic, social and environmental impacts of energy production and consumption in South Africa. Currently, renewable energy contributes relatively little to primary energy and even less to the consumption of commercial energy. This article examines policy options for promoting renewable electricity. Feed-in tariffs guarantee prices for developers, but lack certainty on the amount of renewable electricity such laws would deliver under local conditions. Portfolio standards set a fixed quantity, which would guarantee diversity of supply. The question is whether the incremental upfront cost to be paid by society may be unacceptably high, compared to future health and environmental benefits. A renewables obligation combines the setting of a target with a tendering process, but may be bureaucratic to administer. Neither setting targets or regulating prices alone, however, will be sufficient. Power purchase agreements, access to the grid and creating markets for green electricity are some supporting activities that should be considered. Given that renewable electricity technologies have to compete with relatively low electricity tariffs, funding will be needed. Possible sources, both locally and internationally, are identified. The extent to which these are utilised will determine the future mix of renewable energy in South Africa. (author)

In recent years, the Economic Community of West African States (ECOWAS), comprising 15 Member States, it has emerged as one of the most active and dynamic regional economic communities on the African continent. Expanding access to modern, reliable, and affordable energy services is a key priority, prompting inter-state cooperation in crucial areas including capacity building, policy development and implementation, and investment. Recognising the critical role that sustainable energy plays in catalysing social, economic, and industrial development across the region, ECOWAS Member States formally inaugurated the ECOWAS Centre for Renewable Energy and Energy Efficiency (ECREEE) in 2010 to 'contribute to the sustainable economic, social and environmental development of West Africa by improving access to modern, reliable and affordable energy services, energy security and reduction of energy related externalities'. Drawing on data from the ECOWAS Observatory for Renewable Energy and Energy Efficiency (ECOWREX) and a network of contributors and researchers across the region, the ECOWAS Renewable Energy and Energy Efficiency Status Report supports ECREEE's efforts to increase the deployment of renewable energy and energy efficiency in West Africa by providing a comprehensive regional review of renewable energy and energy efficiency developments, evolving policy landscapes, market trends and related activities, investments in renewable energy and off-grid energy solutions, and the crucial nexus between energy access and gender

2012-06-01

Full Text Available Recently, environmental issues have been the focus of much of the world’s attention. This has stimulated a response in many countries, which has led to a closer examination of energy conservation strategies for conventional fossil fuels. One way of reducing building energy consumption is to design buildings, which are more economical in their use of energy for: heating, lighting, cooling, ventilation and hot water supply. Passive measures, particularly natural or hybrid ventilation rather than air-conditioning, can dramatically reduce primary energy consumption. However, exploitation of renewable energy in buildings and agricultural greenhouses, can significantly contribute in reducing dependency on fossil fuels. Therefore, promoting innovative renewable applications and reinforcing the renewable energy market will contribute to preserving the ecosystem by reducing emissions at local and global levels. This will also contribute to the amelioration of environmental conditions, through a reduction in air pollution and greenhouse gases, by the replacement of conventional fuels with renewable energies.

With the objective of development of the energy mix for the Douai area, a first document reports a study which aimed at examining present modalities of energy supplies and potentials of development of renewable energies on the territory, in order to elaborate a mix energy strategy. This report presents the methodology adopted to acquire data, outlines the necessity to reduce consumptions, comments the distribution of renewable energy production in 2011 and predictions by 2020-2050. It proposes a detailed analysis of mobilisable renewable energies (solar photovoltaic and thermal, wood, geothermal, wind, biogas, waste water heat recovery, micro-hydroelectricity, fatal energies, co-generation). It also discusses the impact on local development in terms of energy dependence, air pollution and financial consequences, and also how to integrate this energetic development into land planning documents. Besides this document, contributions presented during a meeting on renewable energies as a factor of local development are proposed. While addressing the same issues as above, these contributions propose an overview of mobilisable renewable energy sources for the area, outline the interest for local communities to develop their potential in renewable energies, discuss the usefulness of planning documents to promote and ease this development, and discuss how to obtain maximum financial and social fallout from small and large projects of renewable energies

Hydroelectricity and TNB's other renewable energy initiatives

TNB has a big role to play in Malaysia 's pursuit for modernization and socioeconomic progress. The most important task is to fulfill the nation's electricity demand in the most reliable manner and at the lowest cost possible with minimal of environmental impacts. TNB is committed to the development of renewable energy in this country. In fact, hydropower, which is a form of renewable energy, contributed significant proportion of the generating capacity in TNB. Research works on other forms of renewable energy like solar, wind, and biomass are actively being pursued by Tenaga Nasional Research and Development Sdn Bhd. As solar and wind energy systems are by nature emission-free, they provide a ready solution to the current air pollution and global warming problems. With the depletion of conventional non-renewable energy resources like oil, gas, and coal, the emergence of renewable energy as a reliable, alternative source of fuel would enhance security of energy supply in the long run. Because renewable energy is sourced locally, the country will benefit economically due to the cut on imported fuel and hence foreign exchange losses. For the policy makers, the most challenging task ahead is how to re-strategised the present policy on fuels in order to accommodate the contributions from other forms of renewable energy (other than hydro) without compromising on system reliability and cost to the customers. On DSM and Energy Efficiency programs pursued by TNB, the objective in is to discourage wasteful and expensive patterns of energy consumption. In that way, new electricity demand need not necessarily be met by new investment on new power stations. (Author)

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

International Nuclear Information System (INIS)

Mulder, Machiel; Zomer, Sigourney P.E.

2016-01-01

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 energy sector in Europe is going through a dynamic evolution that sees the introduction and development of renewable energy and the re-emergence of a wave energy industry. Although wave energy is currently not economically competitive with mature technologies such as wind energy, the wave energy world-wide resource of 2 TW has a potential contribution in the electricity market of 2000TWh/year. Denmark, Ireland, Portugal, Norway and the UK have been analysed in terms of wave energy resources, renewable energy market structure and political and economic support for the introduction of wave energy into the marketplace. The results have been used together with Ocean Power Delivery Ltd to develop an initial market survey for the wave energy converter Pelamis. (au)

Limits and Prospects of Renewable Energy Sources in Italy

International Nuclear Information System (INIS)

Coiante, D.

2008-01-01

The Italian energy balance for year 2005 is discussed with particular attention on renewable energy production. The potentials of renewable sources are evaluated in terms of energy density that can be obtained from occupied plant area. About 20000 km 2 of sunny barren lands are present in South of Italy, particularly suitable for photovoltaic plants and that corresponds to a potential production of 144 Mtep of primary energy. Therefore, in theory, the photovoltaic energy potential is comparable with energy balance. The grid connection limit due to intermittent power generation of photovoltaic and wind energy systems is considered in relation with the stability of grid power level. Assuming a 25% maximum grid penetration of intermittent power with respect to capacity of active thermoelectric generators, the renewable energy contribution amounts to about 2% of annual energy balance. In front of expectations for a larger contribution, the practical result is the renewable energy production of present systems is marginal, unsuitable for counteracting the global climate crisis. The conclusion is that, for exploiting the large renewable energy potential, is necessary to implement the plants with an energy storage system able to overcome the source intermittency. Without this improvement, the expectations on renewable energy sources could be disappointed. [it

Development of renewable energies in Australia is still in its infancy and will require active support by government, utilities and financing institutions to ensure a steady growth. Much has been done to increase the utilisation of renewable energies in the energy supply, but much still remains to be done, especially in the areas of promotion, demonstration, training and technology transfer. This process will lead to meeting the energy needs of the population in rural areas and to contributing to a suitable development of the region during the next century. Australia is endowed with a wealth of renewable energy resources that hold great promise for addressing a host of important environmental, employment and socioeconomic issues. Australia has a set of climate, geographic and other factors that provide favourable conditions for many specific renewable energy applications. The objectives of this paper is to look at the current situation of renewable energies in Australia, opportunities, constraints, current projects, available potential and future prospects. (Author)

The potential of renewable energy

On June 27 and 28, 1989, the US Department of Energy (DOE) national laboratories were convened to discuss plans for the development of a National Energy Strategy (NES) and, in particular, the analytic needs in support of NES that could be addressed by the laboratories. As a result of that meeting, interlaboratory teams were formed to produce analytic white papers on key topics, and a lead laboratory was designated for each core laboratory team. The broad-ranging renewables assignment is summarized by the following issue statement from the Office of Policy, Planning and Analysis: to what extent can renewable energy technologies contribute to diversifying sources of energy supply What are the major barriers to greater renewable energy use and what is the potential timing of widespread commercialization for various categories of applications This report presents the results of the intensive activity initiated by the June 1989 meeting to produce a white paper on renewable energy. Scores of scientists, analysts, and engineers in the five core laboratories gave generously of their time over the past eight months to produce this document. Their generous, constructive efforts are hereby gratefully acknowledged. 126 refs., 44 figs., 32 tabs.

Choices for A Brighter Future: Perspectives on Renewable Energy

The report discusses the perspectives on the evolving U.S. electricity future, the renewable electric technology portfolio, the regional outlook, and the opportunities to move forward. Renewables are at a critical juncture as the domestic electricity marketplace moves toward an era of increased choice and greater diversity. The cost and performance of these technologies have improved dramatically over the past decade, yet their market penetration has stalled as the power industry grapples with the implications of the emerging competitive marketplace. Renewable energy technologies already contribute to the global energy mix and are ready to make an even greater contribution in the future. However, the renewables industry faces critical market uncertainties, both domestically and internationally, as policy commitments to renewables at both the federal and state levels are being reshaped to match the emerging competitive marketplace. The energy decisions that we make, or fail to make, today will have long-lasting implications. We can act now to ensure that renewable energy will play a major role in meeting the challenges of the evolving energy future. We have the power to choose.

Hain, J.J.; Ault, G.W.; Galloway, S.J.; Cruden, A.; McDonald, J.R.

2005-01-01

This paper summarises the energy policies that the UK Government has enacted in order to achieve its renewable targets by 2010. Current policies are designed primarily to support large-scale renewable projects through Renewable Obligation Certificates, Levy Exemption Certificates and capital grant schemes. Non-profit domestic and non-profit community renewable projects are also eligible for grant support. First-hand experience of privately owned renewable projects indicate that existing renewable policy is insufficient in its support of both small-scale and community-based profit oriented renewable energy (RE) schemes. Primary and secondary survey information suggests that people living in regions where RE will be situated may generally be inclined to support broader uses of renewables in these regions. Small-scale renewables can make a significant cumulative contribution to the RE mix. The results reported in this paper support the contention that the Government could go further towards approaching its targets through rural-focused changes to its energy incentive programmes

Interactions of Policies for Renewable Energy and Climate

2011-07-01

This paper explores the relationships between climate policy and renewable energy policy instruments. It shows that, even where CO2 emissions are duly priced, specific incentives for supporting the early deployment of renewable energy technologies are justified by the steep learning curves of nascent technologies. This early investment reduces costs in the longer term and makes renewable energy affordable when it needs to be deployed on a very large scale to fully contribute to climate change mitigation and energy security. The paper also reveals other noteworthy interaction effects of climate policy and renewable policy instruments on the wholesale electricity prices in deregulated markets, which open new areas for future research.

This study examines the possible evolution of Victorian energy markets over the 1998-2030 period from technical, economic and environmental perspectives. The focus is on the technical and economic potential over the study period for renewable energy and energy efficiency to increase their share of energy markets, through their economic competitiveness with the non-renewables of oil, gas and fossil fulled electricity. The study identifies a range of energy options that have a lower impact on carbon dioxide emissions that current projections for the Victorian energy sector, together with the savings in energy, dollars and carbon dioxide emissions. In addition the macroeconomic implications of the energy paths are estimated. Specifically it examines a scenario (R-efficient renewable) where energy efficiency and renewable energy sources realise their estimated economic potential to displace non-renewable energy over the 1988-2030 period. In addition, a scenario (T-Toronto) is examined where energy markets are pushed somewhat harder, but again on an economic basis, so that what is called the Toronto target of reducing 1988 carbon dioxide (CO 2 ) emissions by 20 per cent by 2005 is attained. It is concluded that over the next forty years there is substantial economic potential in Victoria for significant gains from energy efficiency in all sectors - residential, commercial, industrial and transport - and contributions from renewable energy both in those sectors and in electricity generations. 7 figs., 5 tabs

A critical assessment of renewable energy usage in the USA

Klass, Donald L.

2003-01-01

The displacement of non-renewable fossil fuels by renewable energy resources has occurred at a low rate in the USA. But a large number of drivers is expected to cause significant expansion of the US renewable energy industry in the near future. Included among the extrinsic drivers, or those that are not directly related to renewable energy resources, are reductions in natural gas and crude oil supplies and the OPEC Effect. An assessment of petroleum crude oil and natural gas consumption and reserves supports the position that supply problems and significant cost increases will start to occur in the first and second quarters of this century. Among the intrinsic drivers, or those that are directly related to renewable energy resources, are global warming and specific government incentives and mandates such as Renewable Portfolio and Fuel Standards that require the commercial use of renewable energy resources. The increasing US dependence on imported crude oil and environmental and political issues will drive the growth of the renewable energy industry and result in the gradual phase-out of what can be called the Fossil Fuel Era. By the end of this century, the dominant commercial energy mix in the USA is projected to include major contributions by renewable energy resources to help satisfy energy and fuel demands. Practical solutions to the problems of disposing of spent nuclear fuels and the development of clean coal applications will enable these energy resources to afford major contributions also

Energy efficiency and renewable energy production contribute to the three major goals of the national energy policy of the Czech Republic: overall competitiveness, security of supply; and environmental protection. Therefore, the Czech government promotes these two sustainable options. The Energy Policy White Paper, which is being developed at the time of writing (June 1999), will provide the general framework for the future role of energy efficiency and renewable energy in the Czech Republic. However, in addition, it is necessary to develop specific policies. The National Energy Efficiency Study aimed to support the Czech government in the formula tion of energy efficiency and renewable energy policy. The National Energy Efficiency Study has resulted in the following documents: (1) The Renewable Energy Action Plan (this report) addresses renewable energy production. The Energy Efficiency Action Plan focuses on the promotion of energy efficiency in end use (separate report; ECN-C--99-065). These two Action Plans provide policy makers in the Czech government with information on potentials, targets, budgets and recommended policy instruments. The core of the Action Plans is the list of concrete policy actions, ready for implementation; (2) The National Energy Efficiency Study NEES (separate report; ECN-C--99-063). This report is the background document to the two Action Plans. It contains detailed information on options and measures, potentials, barriers and policy instruments for energy efficiency and renewables. The main part is a detailed outline for a new energy efficiency and renewable policy. Also, it includes recommendations for financing schemes to overcome the invest ment constraints in the Czech Republic. Finally, a list of concrete projects is included to support project identification

Renewable energy technologies: costs and markets

International Nuclear Information System (INIS)

Nitsch, J.; Langniss, O.

1997-01-01

A prominent feature of renewable energy utilisation is the magnitude of renewable energy that is physically available worldwide. The present paper attempts an economic valuation of development strategies for renewable energy sources (RES) on the basis of the past development of RES markets. It comes to the conclusion that if current energy prices remain largely unchanged, it will be necessary to promote RES technologies differentially according to the technique and type of energy employed or to provide start-up funding. The more probable a long-term increase in energy prices becomes, the greater will be the proportion of successfully promoted technologies. Energy taxes on exhaustible or environmentally harmful energy carriers and other instruments to this end would contribute greatly to the attractivity of RES investment both in terms of national economy and from the viewpoint of the private investor. Renewable energies will play an important role in the hardware and services sectors of the energy market in the decades to come. Long-term promotion of market introduction programmes and unequivocal energy-political aims on the part of the government are needed if the German industry is to have a share in this growing market and be able to offer internationally competitive products [de

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

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

Developing markets for renewable energy technologies

Charters, W.W.S.

2001-01-01

Although renewable energy resources are now being utilised more on a global scale than ever before, there is no doubt their contribution to the energy economy can still be greatly increased. Recently international support for developing these relatively new sources of energy has been driven by their benefits as assessed by reduced environmental impact, particularly reduced greenhouse gas emissions. After several decades of continuous but somewhat erratic funding for research and development of renewables, it is time to take stock of the key issues to be addressed in terms of implementation of major renewable energy programmes on a large scale worldwide. One of the first steps in this process is the identification and encouragement of reliable continuous markets both in developed and developing nations. Future energy policy and planning scenarios should take into account the factors necessary to integrate renewables in all their diverse forms into the normal energy economy of the country. Other critical factors in market development will include the mass production of high quality, reliable and reasonable cost technical products and the provision of adequate finance for demonstrating market ready and near market renewables equipment. Government agencies need to aid in the removal of legislative and institutional barriers hindering the widespread introduction of non-conventional energy sources and to encourage the implementation of government purchasing schemes. Recent moves by companies in Australia to market 'green energy' to customers should also aid in the public awareness of the ultimate potential of renewables leading to greater use in the industrial, commercial and domestic sectors.

The goal is to reduce dependence on fossil fuels to generate electricity and to reduce the emission of greenhouse gases. In this article we analyse the current state of renewable energies, the conditions needed to foster them and the legislative changes already introduced to promote their greater part in the national electricity grid.

energy sources in relation to other energy sources. The objective in the long term is to make them as competitive as possible in the open energy market. Among those measures of crucial importance included in the Action Plan, we can mention development and commercialisation of new technology as well as several financial measures, of which taxation and investment aid are considered to have the greatest effect. In addition, the Action Plan presents several administrative measures for the promotion of renewable energy sources. A separate assessment of the environmental impact of the Action Plan has been made resulting in an environmental impact statement (EIS) that contains a detailed account of the environmental impacts of the use of renewable energy sources and the use of peat in energy production. The most important environmental impact of the implementation of the Action Plan will be a reduction in greenhouse gas emissions. As a result of the intensified measures to be taken in accordance with the Action Plan, carbon dioxide emissions are estimated to be reduced at least by 2 million tons per year compared with the outlook presented in the Energy Strategy. Further, the use of waste, which otherwise would have been transported to tips, in energy production is estimated to reduce methane emissions by 1 million ton per year (C0 2 equivalent). The reduction might be even much bigger in the next few years. To ensure that the objectives of the Action Plan will be achieved, the contribution by the State (tax subsidies, investment aid and other forms of aid) should be approx. FIM 500 million on an average per year in the next ten years. In 1998, the State's contribution exceeded FIM 300 million. Further, financing amounting to approx. FIM 200 million is channelled to the research on and the development of energy production technology, which in the future to a larger extent than now will be channelled to the development of such forms of energy production technology that are using

The potential contribution of renewable energy to electricity supply in Saudi Arabia

Saudi Arabia has enormous oil resources. At the same time, the Kingdom has other resources, notably solar energy that may figure in future supplies of electricity. In the past several years, considerable operational experience has been gained throughout the world in the implementation of renewable energy systems of types that would be relevant to the Kingdom. This paper reviews the nature of this experience and applies it in a quantitative assessment of the costs, savings, and environmental benefits of renewable energy conducted as a part of an electric utility integrated resource planning (IRP) project in the Kingdom. Integrated resource planning is an approach that systematically evaluates potential electricity supply and demand-side resources with the aim of developing a plan that provides energy services to customers at the least societal cost. The analysis summarized in this paper has shown that, when some of the non-market benefits of renewable energy are also included in the assessment of their overall costs and benefits, a supply expansion plan that includes wind and solar resources can provide energy services for the Kingdom at a lower societal cost than a 'Business-as-usual' plan utilizing only fossil-fueled generating resources

This is the fourth annual report published by the Energy Information Administration (EIA) which presents information on renewable energy consumption, capacity, and electricity generation data; US solar thermal and photovoltaic collector manufacturing activities; and US geothermal heat pump manufacturing activities. It updates and provides more detail on renewable energy information than what`s published in the Energy Information Administration`s (EIA) Annual Energy Review 1997. The renewable energy resources included in the report are: biomass (wood, wood waste, municipal solid waste, ethanol, and biodiesel); geothermal; wind; solar (solar thermal and photovoltaic); and hydropower. However, hydropower is also regarded as a conventional energy source because it has furnished a significant amount of electricity for more than a century. Therefore, the contribution of hydropower to total renewable energy consumption is discussed, although hydropower as an individual energy source is not addressed. Since EIA collects data only on terrestrial (land-based) systems, satellite and military applications are not included in this report. 13 figs., 44 tabs.

The potential for renewable energy use in Canada is examined. It is pointed out that Canada can choose to begin to diversify its energy supply now, moving rapidly and smoothly towards an efficient energy society based on renewable energy sources; or, it can continue on its present course and face the possibility of being forced by necessity to make a later transition to renewable sources, probably with a great deal of economic and political disruption. The handbook begins with a discussion on major issues and options available. This second section deals with the technology, applications, and costs of direct solar energy utilization, solar thermal electricity generation, photovoltaic conversion, wind energy, biomass energy, tidal power, wave energy, ocean thermal energy, geothermal energy, heat pumps, and energy storage. Section three discusses how renewable energy might realistically supply Canada's energy requirements within a reasonable period of time. Some issues on how government, industry, and the individual may become involved to make this happen are suggested. A list of resource people and renewable energy businesses is provided in the last section. A recommended reading list and bibliography complete the handbook. (MCW)

The Clean Air Renewable Energy Coalition promotes the development of the renewable energy industry in Canada. It acknowledges the effort that the Canadian government has taken to advance investment in renewable energy, but the Coalition is concerned that these investments alone will not achieve the desired objectives without additional policy development by federal, provincial and territorial governments. This report presents an overview of 7 proposals designed to promote and advance renewable energy in Canada. The benefits of these proposals include cleaner air, improved health, engaging public and industry participation in climate change initiatives, and fostering innovation and entrepreneurship in the sector. Brief details were presented for the following 7 proposals: (1) establish a national low-impact renewable energy target for Canada, (2) increase the Wind Power Production Incentive (WPPI) to 2.7 cent per kilowatt hour to ensure appropriate investment in wind energy and harmonization with the United States, (3) extend incentive programs similar to the WPPI to other renewable energy technologies, (4) work with other levels of government to implement policy mechanisms to meet the recommended national renewable energy target, (5) expand the Market Incentive Program (MIP) funding to 30 million dollars per year to 2012 and consult with the provinces and territories to develop a broad-based consumer green energy rebate and education program, (6) identify mechanisms to ensure a meaningful role for renewable energy to contribute to the country's climate change strategy, and (7) develop a Wind Energy Mapping and Wind Measurement Initiative. In a recent update, the Coalition states that low environmental impact renewable energy needs market recognition for its environmental and social benefits.

This study explores the causal relationship between carbon dioxide (CO 2 ) emissions, renewable and nuclear energy consumption and real GDP for the US for the period 1960-2007. Using a modified version of the Granger causality test, we found a unidirectional causality running from nuclear energy consumption to CO 2 emissions without feedback but no causality running from renewable energy to CO 2 emissions. The econometric evidence seems to suggest that nuclear energy consumption can help to mitigate CO 2 emissions, but so far, renewable energy consumption has not reached a level where it can make a significant contribution to emissions reduction.

We study systemic risk and dependence between oil and renewable energy markets using copulas to characterize the dependence structure and to compute the conditional value-at-risk as a measure of systemic risk. We found significant time-varying average and symmetric tail dependence between oil returns and several global and sectoral renewable energy indices. Our evidence on systemic risk indicates that oil price dynamics significantly contributes around 30% to downside and upside risk of renewable energy companies. These results have important implications for risk management and renewable energy policies. - Highlights: • We study systemic risk and dependence between oil and renewable energy markets. • Dependence and conditional value-at-risk is obtained through copulas. • Oil and renewable energy displayed time-varying average and symmetric tail dependence. • Oil price contribution to the downside and upside risks of renewable energy companies was around 30%

The main goal of Latvian energy policy is to ensure safe and environmentally friendly long-term energy supply at cost-effective prices, contributing to enhance competitiveness, and to ensure safe energy transit. The Latvian Parliament approved an Energy Efficiency Strategy in 2000. Its objective is to decrease energy consumption per unit of GDP by 25% by 2010. Awareness raising, implementation of standards and economic incentives for self financing are the main instruments to increase energy efficiency, mentioned in the strategy. Latvia, as many other European Union member states, is dependent on the import of primary energy resources. The Latvian Renewable Energy strategy is still under development. The only recent study on RES was developed in the framework of a PHARE program in year 2000: "Renewable energy resource program", where three main objectives for a future RES strategy were proposed: 1. To increase the use of wood waste and low value wood and forest residues. 2. To improve efficiency of combustion technologies and to replace outdated plants. 3. To increase the use of renewables in Combined Heat and Power plants (CHP). Through the Renewable Energy and Energy Efficiency Partnership, partners will develop a set of new shared activities, and coordinate and strengthen existing efforts in this area.

A Renewable Energy Exporters Network (REEN) has recently been established, following a meeting of renewable energy exporters and government agencies on 30 October 2000. REEN will assist the Australian renewable energy industry to take advantage of the opportunities offered by the burgeoning global market for renewable energy goods and services. Recent estimates of the significant potential global growth is renewable energy demand have reinforced the industry and Government's view that, in the medium to long-term, growth in the Australian renewable energy industry will largely depend on capturing export market share. Expanding the export market was identified as a crucial component in the Renewable Energy Action Agenda, developed jointly by industry and Government and released in June 2000. It was estimated that, for the industry to achieve its vision of sales of $4 billion per year by 2010, exports would need to comprise approximately 50% of the forecast growth in sales. As such, the need for a specific export strategy for the Australian renewable energy industry was recognised in the Action Agenda, and the establishment of the REEN is one of the first initiatives undertaken as part of the Renewable Energy Export Strategy. The REEN comprises approximately 50 export-ready renewable energy companies, the Department of Industry, Science and Resources, Austrade, and Stage Government agencies such as NSW's Sustainable Energy Development Authority. The Export Network will operate electronically, with face-to-face meetings held as appropriate. The Department of Industry, Science and Resources will facilitate the Export Network and has published a website at www.isr.gov.au/industry/reen. The site includes: a members directory; a discussion forum; information on opportunities to showcase Australian renewable; energy products and services; and Iinks to sites containing information that may be useful to renewable energy exporters.

2008-07-01

In some European Union (EU) States community owned renewable projects have made a major contribution to the development of renewables as a whole, and this project wishes to build on their success. Other states have yet to establish relatively significant community renewable sectors. Community Renewable Energy (CoRE) has developed a new social enterprise franchise model to accelerate the take-up of renewable energy technologies across the EU. The model focuses on the three difficulties faced by communities wishing to develop renewable energy in a globalized and deregulated energy market. CoRE provides support in the forms of time, money and expertise, as a central function, to a federated or cooperative membership. In return CoRE takes a share of profits from each community project that it works with to cover its running costs, work with more communities and develop financial mechanisms to fund futher projects. The plan is to set up CoRE Europe to enable communities to become part of a decentralized energy network and share resources and knowledge. It will add to community sustainability and resilience, develop and support a range of other community benefits, for example: job creation, tackling fuel poverty and empowering communities in meeting the climate change challenge.

2006-01-01

The current Austrian energy system has a renewable energy share of 20% - 11% hydropower and 9 % biomass - of total primary energy consumption. Whereas a possible future introduction of renewable hydrogen must be seen in the context of current energy policies in Austria e.g. increase of energy efficiency and use of renewable energy, reduction of greenhouse gas emissions. The aim of the research project is a life cycle based comparison of energy systems with renewable hydrogen from hydropower, wind, photovoltaic and biomass compared to the direct use of renewable energy for combined heat and power applications and transportation services. In particular this paper focuses on the main question, if renewable energy should be used directly or indirectly via renewable hydrogen. The assessment is based on a life cycle approach to analyse the energy efficiency, the material demand, the greenhouse gas emissions and economic aspects e.g. energy costs and some qualitative aspects e.g. energy service. The overall comparison of the considered energy systems for transportation service and combined heat and electricity application shows, that renewable hydrogen might be beneficial mainly for transportation services, if the electric vehicle will not be further developed to a feasibly wide-spread application for transportation service in future. For combined heat and electricity production there is no advantage of renewable hydrogen versus the direct use of renewable energy. Conclusions for Austria are therefore: 1) renewable hydrogen is an interesting energy carrier and might play an important role in a future sustainable Austrian energy system; 2) renewable hydrogen applications look most promising in the transportation sector; 3) renewable hydrogen applications will be of low importance for combined heat and electricity applications, as existing technologies for direct use of renewable energy for heat and electricity are well developed and very efficient; 4) In a future '100

Renewable energy. Market and policy trends in IEA countries

International Nuclear Information System (INIS)

2004-01-01

Renewable energy has received high levels of attention in recent years as an alternative to traditional hydrocarbons. Governments, industry and consumers have adopted and promoted renewable technologies in response to concerns about energy security and the environment, and as a solution to electricity access problems in developing countries. To what degree has renewable energy gained a share in the energy mix? What lessons can be learned from efforts made thus far? Renewable Energy - Market and Policy Trends in IEA Countries reviews the experience of IEA countries after the oil crisis in the 1970's initiated a surge of investments in renewables research and development. While use of renewables has grown rapidly, they still account for only a small portion of the IEA energy mix. Hydropower, bio-energy and geothermal energy are mature technologies that contribute about 5 - 6% to primary energy supply. Solar, wind, and other new renewables have experienced rapid technology development, but as yet they represent only a small share. This work examines policies and measures that have been introduced in IEA countries to increase the cost effective deployment of renewables, reviews the objectives behind these policies, and evaluates the results. The aim is to identify best practices in order to assist governments in making future policy decisions

Since Taiwan imports more than 99% of energy supply from foreign countries, energy security has always been the first priority for government to formulate energy policy. The development of renewable energy not only contributes to the independence of energy supply, but also achieves benefits of economic development and environmental protection. Based upon information available to public, the present paper reassesses reserves of various renewable energies in Taiwan. The assessment includes seven kinds of renewable energies, namely, solar energy, wind power, biomass energy, wave energy, tidal energy, geothermal energy and hydropower, which are all commercialized and matured in terms of current technologies. Other renewable energies, which have not proven as matured as the aforementioned ones, are only assessed preliminarily in this paper, such as second generation of biomass, deep geothermal energy, the Kuroshio power generation and ocean thermal energy conversion. According to the estimation of this paper, the reserve of wind energy, up to 29.9 kWh/d/p (i.e., kWh per day per person), is the largest one among seven kinds of renewable energies in Taiwan, followed by 24.27 kWh/d/p of solar energy, 4.55 kWh/d/p of biomass, 4.58 kWh/d/p of ocean energy, 0.67 kWh/d/p of geothermal energy and 16.79 kWh/d/p of hydropower. If regarding biomass as a primary energy, and assuming 40% being the average efficiency to convert primary energy into electricity, the total power of the seven kinds of renewable energy reserves is about 78.03 kWh/d/p, which is equal to 2.75 times of 28.35 kWh/d/p of national power generation in 2008. If the reserves of 54.93 kWh/d/p estimated from other four kinds of renewable energies that have not technically matured yet are also taken into account, it will result that the reserves of renewable energy in Taiwan can be quite abundant. Although the results of the assessment point out that Taiwan has abundant renewable energy resources, the four inherent

Japan, South Korea, and Taiwan are deficient of domestic fossil energy sources and depend significantly on imported fuels. Since the oil shock in the 1970s, all three countries have promoted renewable energy as an alternative energy source to improve energy security. Currently, renewable energy is being promoted to build low-carbon economies. This study reviews the development of renewable energy policies and roadmaps. It also examines and compares strengths, weaknesses, opportunities, and threats (SWOT) of these countries in the context of advancing renewable energy policies and technologies and expanding domestic renewable energy installations, as well as strategically positioning themselves in the international renewable energy market as exporters of clean energy technologies. Through the SWOT analysis, this paper identifies a capacity for additional renewable energy deployment in these countries and highlights the necessity of increased cooperation between the three countries to strengthen their domestic and regional renewable energy sectors and compete in the global renewable energy market in the post-Fukushima era. - Highlights: • Japan, South Korea and Taiwan need to develop renewable energy (RE). • These countries have been too conservative to achieve a notable share of RE. • Pro-nuclear energy policies have hindered the RE development in these countries. • The Fukushima disaster made these countries more favorable to RE. • Joint cooperation for R and D and deployment of RE is recommended

Although the need to decarbonise our global economy and thus in particular the supply of energy to limit the global temperature increase is internationally undisputed the German politics in 2014 has significantly contributed less compared to previous years in order to attain this objective. The expansion of renewable energies in the electricity sector has decelerated significantly; and in the heating and mobility area no new impulses were set in relation to renewable energies. In addition, a dramatic fallen oil price makes it difficult to increase the use of renewable energy supply. Based on these deteriorated framework conditions compared to conditions of the previous years, the developments in Germany of 2014 are shown in the electricity, heat and transport sector in the field of renewable energy. For this purpose - in addition to a discussion of the current energy economic framework - for each option to use renewable energies the state and looming trends are analyzed. [German] Obwohl die Notwendigkeit zur Dekarbonisierung unserer globalen Wirtschaft und damit insbesondere der Energiebereitstellung zur Begrenzung des globalen Temperaturanstiegs international unstrittig ist, hat die deutsche Politik im Jahr 2014 im Vergleich zu den Vorjahren deutlich weniger zur Erreichung dieses Zieles beigetragen. Der Ausbau der Stromerzeugung aus erneuerbaren Energien im Stromsektor wurde deutlich verlangsamt; und im Waerme- und Mobilitaetsbereich wurden keine neuen Impulse in Bezug auf regenerative Energien gesetzt.

Full Text Available Concern over global climate change as a result of fossil fuel use has resulted in energy production from renewable sources. Marine renewable energy devices provide clean electricity but can also cause physical disturbance to the local environment. There is a considerable paucity of ecological data at potential marine renewable energy sites that is needed to assess potential future impacts and allow optimal siting of devices. Here, we provide a baseline benthic survey for the Big Russel in Guernsey, UK, a potential site for tidal energy development. To assess the suitability of proposed sites for marine renewable energy in the Big Russel and to identify potential control sites, we compared species assemblages and habitat types. This baseline survey can be used to select control habitats to compare and monitor the benthic communities after installation of the device and contribute towards the optimal siting of any future installation.

Highlights: • Off-grid renewable power generation in a smart mini-grid perspective. • Direct measurements and CFD simulation for energy resources and consumption. • Detailed distribution of wind resource in the Khumbu Valley, Everest region, Nepal. • PV/wind system with storage device, for emergency and permanent scenarios. • Important wind contribution to the energy balance and positive environmental assessment. - Abstract: Governments around the world strive to achieve ambitious targets of incorporating considerable amounts of distributed renewable generation and combined heat and power, in response to the climate-change challenge and the need to enhance fuel diversity. The scientific interest is moving toward off-grid power generation systems, based on conventional and/or renewable sources, often coupled with storage devices, which distribute power through a local grid network. This approach, applied to increase electricity access especially in remote areas, is effective to reduce poverty, mitigate climate change and improve the resilience. In this framework, the paper presents the assessment of different renewable sources for power generation in Nepal, aimed to (i) optimize the energy fluxes, (ii) evaluate the long term energy balance by comparing productions and consumption, (iii) preliminary size a multiple input/output storage device on the basis of specific boundary conditions. The study is geographically set within the Khumbu Valley, in the central part of the Himalayan Range, East Region of Nepal, recently damaged by severe seismic events causing serious consequences on population and territory. The specific features of the reference context have been assessed from different points of view, focusing on climate data, energy consumption, and available resources. Wind potential in several spots around Namche Bazar region was estimated using CFD methods, and a customized micro wind turbine – projected by University of Perugia – has been

A future energy policy equally has to pursue environmental protection and climate protection, economic efficiency as well as supply security. Renewable energies substantially contribute to this. In the last decade, the Federal Government of Germany showed that a strong development of renewable energies is possible within a short time. For the year 2020, the industry prognosticates an amount of the renewable energies of 47 % at the consumption of electricity, 25 % at the heat consumption, and 22 % at the fuel consumption in the traffic. The contribution under consideration shows that the surface which is needed for this is small. Depending upon climate, landscape, settlement structure and agrarian structure, each region offers its own different potentials.

Full Text Available The scientific evidence of climate change as a result of greenhouse gas emissions which causes ozone layer depletion is becoming increasingly obvious and clear. Findings revealed that energy from the fossil fuel is the major source of greenhouse emission which destroys the environment and makes it unhealthy for living beings. In Nigeria, conventional energy (oil and gas with gas flaring has the highest percentage of 52% and liquid fuel of 32% of carbon dioxide (CO2 respectively. This sector contributes revenue of over 70% to Nigeria’s economy and generates an average total 21.8% of greenhouse gas emission. In Nigeria, there is a much more potential for share renewables with 15.4% of total energy production and 8.6 % of energy consumption. In reality with global environmental concern, Nigeria’s carbon dioxide emissions have increased with energy production and consumption. The Integrated Renewable Energy Master Plan of 2008 projects a 26.7% renewable energy contribution to the Nigeria’s energy use and this is expected to reduce CO2 and greenhouse gas emissions at 38% by2025. Nigeria has not been playing significant role by reducing emissions of greenhouse gases. This paper highlights Nigeria’s climate change situation and penetration requirements for various renewable energy deployments as mitigating instrument for climate change towards healthy and productive environment.

Full Text Available Nowadays, renewable energy is gaining more attention than other resources for electricity generation in the world. For Afghanistan that has limited domestic production of electric power and is more dependent on the unstable imported power from neighboring countries which pave the way to raise the cost of energy and increased different technical and economic problems. The employment of renewable energy would not only contribute to the independence of energy supply but also can achieve the socio-economic benefits for the country which is trying to rebuild its energy sector with a focus on sustainable energy for its population. From a theoretical point of view, there is a considerable potential of renewable energies such as solar energy, wind power, hydropower, biomass and geothermal energy available in the country. However, despite the presence of widespread non-agricultural and non-residential lands, these resources have not been deployed efficiently. This paper assesses the theoretical potential of the aforementioned types of renewable energies in the country. The study indicates that deployment of renewable energies can not only supplement the power demand but also will create other opportunities and will enable a sustainable energy base in Afghanistan.

Non-renewable and renewable energy consumption and CO2 emissions in OECD countries: A comparative analysis

Shafiei, Sahar; Salim, Ruhul A.

2014-01-01

This paper attempts to explore the determinants of CO 2 emissions using the STIRPAT model and data from 1980 to 2011 for OECD countries. The empirical results show that non-renewable energy consumption increases CO 2 emissions, whereas renewable energy consumption decreases CO 2 emissions. Further, the results support the existence of an environmental Kuznets curve between urbanisation and CO 2 emissions, implying that at higher levels of urbanisation, the environmental impact decreases. Therefore, the overall evidence suggests that policy makers should focus on urban planning as well as clean energy development to make substantial contributions to both reducing non-renewable energy use and mitigating climate change. - Highlights: • Examine the relationship between disaggregated energy consumption and CO 2 emission. • The STIRPAT econometric model is used for empirical analysis. • Investigate the popular environmental Kuznets curve (EKC) hypothesis between urbanisation and CO 2 emissions. • Non-renewable energy consumption increases CO 2 emissions whereas renewable energy consumption decreases CO 2 emissions. • There is evidence of the existence of an environmental Kuznets curve between urbanisation and CO 2 emissions

Using net energy output as the base to develop renewable energy

In order to increase energy security, production of renewable energies has been highly promoted by governments around the world in recent years. The typical base of various policy instruments used for this purpose is gross energy output of renewable energy. However, we show that basing policy instruments on gross energy output will result in problems associated with energy waste, economic inefficiency, and negative environmental effects. We recommend using net energy output as the base to apply price or quantity measures because it is net energy output, not gross energy output, which contributes to energy security. The promotion of gross energy output does not guarantee a positive amount of net energy output. By basing policy instruments on net energy output, energy security can be enhanced and the above mentioned problems can be avoided.

Roughly 400 million households, or 40% of the population of developing countries, do not have access to electricity. Household and community demand for lighting, TV, radio, and wireless telephony in rural areas without electricity has driven markets for solar home systems, biogas-fueled lighting, small hydro mini-grids, wind or solar hybrid mini-grids, and small wind turbines. These technologies are not strictly comparable with each other, however; the level of service that households receive varies considerably by technology and by the specific equipment size used. Regardless of size, surveys and anecdotal evidence suggest that rural households value both electric lighting and television viewing. Growing numbers of individual equipment purchases, beyond government-driven programs, point to growing market demand. As energy consumption rises with increases in population and living standards, awareness is growing about the environmental costs of energy and the need to expand access to energy in new ways. As recognition grows of the contribution renewable energy can make to development, renewable energy is shifting from the fringe to the mainstream of sustainable development. Support for renewable energy has been building among those in government, multilateral organizations, industry, and non-governmental organizations. Commercial markets for renewable energy are expanding, shifting investment patterns away from traditional government and donor sources to greater reliance on private firms and banks. In this paper we take a market orientation, providing an aggregate review of past market experience, existing applications, and results of policies and programs. (BA)

The EurObserv'ER policy profiles give a snapshot of the renewable energy policy in the EU Member States. Malta's RES target for 2020 is 10%. By 2015, Malta had reached a RES share of 5%. Due to several major technology-related developments, Malta has revised the originally planned RES mix presented in its 2010 NREAP. Whilst offshore wind is no longer expected to contribute to reaching the target, installation of solar PV systems is given higher priority. Malta uses a combination of feed-in tariffs, grant schemes and a quota obligation on the share of bio-fuels delivered on the market to promote renewable energy sources

What drives renewable energy development?

Alagappan, L.; Orans, R.; Woo, C.K.

This viewpoint reviews renewable energy development in 14 markets that differ in market structure (restructured vs. not restructured), use of feed-in-tariff (FIT) (yes vs. no), transmission planning (anticipatory vs. reactive), and transmission interconnection cost allocated to a renewable generator (high vs. low). We find that market restructuring is not a primary driver of renewable energy development. Renewable generation has the highest percent of total installed capacity in markets that use a FIT, employ anticipatory transmission planning, and have loads or end-users paying for most, if not all, of the transmission interconnection costs. In contrast, renewable developers have been less successful in markets that do not use a FIT, employ reactive transmission planning, and have generators paying for most, if not all, of the transmission interconnection costs. While these policies can lead to higher penetration of renewable energy in the short run, their high cost to ratepayers can threaten the economic sustainability of renewable energy in the long-run. - Highlights: → Market structure seems to have little effect on renewable energy development. → Renewable energy development is more successful in markets that use a FIT. → Anticipatory transmission planning aids renewable energy development. → Low interconnection costs for developers also aids renewable energy development.

Required storage capacity to increase the value of renewable energy

International Nuclear Information System (INIS)

Nacht, T.

2014-01-01

The effort to achieve a more eco - friendly production of energy leads to larger shares of renewables in the electricity sector, resulting in more supply - dependency and volatility. This results in a time shift between production and consumption. In order to gain an upper hand, possibilities for transferring renewable energies from the time of production to the time when the demand occurs are researched. Energy storage systems will play a big role in this process, with pumped storage plants being the most developed and most common technology nowadays. As a first part of this thesis, the renewables in Germany are studied through the use of models on the basis of hourly measured values of the primary energy carriers for the corresponding technology. For these data series many years’ worth of measurements were considered, resulting in data for the hourly production values of the renewable energy sources. The results show a strong dependency between production and the seasons of the year. Furthermore a very small secured contribution of renewable production during times of peak load is registered, leading to the conclusion that energy storages are indeed necessary. Different strategies for the dispatch of the storage technologies pumped hydro storage, compressed air storage and hydrogen storage are developed for the region of Germany, which will be dispatched outside the energy - only market. The different strategies for the storage dispatch have the reduction of the resulting load in common, by preferably transferring renewable energy from times when it is not needed to those times with high loads. This resulting load needs to be covered by thermal power plants. The required capacities of the different storage technologies are evaluated and compared. By using pumped storage plants the increase in the value of renewables, as measured by the secure contribution during peak load hours, is determined. An analysis of different compositions of renewable production allows

With limited indigenous conventional energy resources, Taiwan imports over 99% of its energy supply from foreign countries, mostly from the Middle East. Developing independent renewable energy resources is thus of priority concern for the Taiwanese government. A medium subtropical island surrounded by the Pacific Ocean, Taiwan has enormous potential to develop various renewable energies, such as solar energy, biomass energy, wind power, geothermal energy, hydropower, etc. However, owing to the importance of conventional fossil energy in generating exceptionally cheap electricity, renewable energy has not yet fully developed in Taiwan, resulting from a lack of market competition. Consequently, numerous promotional and subsidy programs have recently been proclaimed by the Taiwanese government, focused on the development of various renewables. This study reviews the achievements, polices and future plans in this area. (author)

The dynamic development and implementation of technologies based on renewable energy sources (hereinafter RES is the defining trend of world energy development. The uneven distribution of hydrocarbon reserves, increasing demand of developing countries and environmental risks associated with the production and consumption of fossil resources has led to an increasing interest of many states to this field. Creating low-carbon economies involves the implementation of plans to increase the proportion of clean energy through renewable energy sources, energy efficiency, reduce greenhouse gas emissions. The priority of this sector is a characteristic feature of modern development of developed (USA, EU, Japan and emerging economies (China, India, Brazil, etc., as evidenced by the inclusion of the development of this segment in the state energy strategies and the revision of existing approaches to energy security. The analysis of the use of renewable energy, its contribution to value added of countries-producers is of a particular interest. Over the last decade, the share of energy produced from renewable sources in the energy balances of the world's largest economies increased significantly. Every year the number of power generating capacity based on renewable energy is growing, especially, this trend is apparent in China, USA and European Union countries. There is a significant increase in direct investment in renewable energy. The total investment over the past ten years increased by 5.6 times. The most rapidly developing kinds are solar energy and wind power.

2010-01-01

This paper examines the causal relationship between CO 2 emissions, nuclear energy consumption, renewable energy consumption, and economic growth for a group of 19 developed and developing countries for the period 1984-2007 using a panel error correction model. The long-run estimates indicate that there is a statistically significant negative association between nuclear energy consumption and emissions, but a statistically significant positive relationship between emissions and renewable energy consumption. The results from the panel Granger causality tests suggest that in the short-run nuclear energy consumption plays an important role in reducing CO 2 emissions whereas renewable energy consumption does not contribute to reductions in emissions. This may be due to the lack of adequate storage technology to overcome intermittent supply problems as a result electricity producers have to rely on emission generating energy sources to meet peak load demand.

Biomass is a renewable energy source and its importance will increase as national energy policy and strategy focuses more heavily on renewable sources and conservation. Biomass is considered the renewable energy source with the highest potential to contribute to the energy needs of modern society for both the industrialized and developing countries worldwide. The most important biomass energy sources are wood and wood wastes, agricultural crops and their waste byproducts, municipal solid waste, animal wastes, waste from food processing, and aquatic plants and algae. Biomass is one potential source of renewable energy and the conversion of plant material into a suitable form of energy, usually electricity or as a fuel for an internal combustion engine, can be achieved using a number of different routes, each with specific pros and cons. Currently, much research has been focused on sustainable and environmental friendly energy from biomass to replace conventional fossil fuels. The main objective of the present study is to investigate global potential and use of biomass energy and its contribution to the sustainable energy development by presenting its historical development.

India has done a significant progress in the power generation in the country. The installed generation capacity was 1300 megawatt (MW) at the time of Independence i.e. about 60 years back. The total generating capacity anticipated at the end of the Tenth Plan on 31-03-2007, is 1, 44,520 MW which includes the generation through various sectors like Hydro, Thermal and Nuclear. Emphasis is given to the renewable energy programme towards gradual commercialization. This programme is looked after by the Ministry of Non-Conventional Sources of energy. Since the availability of fossil fuel is on the decline therefore, in this backdrop the norms for conventional or renewable sources of energy (RSE) is given importance not only in India but has attracted the global attention. The main items under RSE are as follows: (i) Hydro Power (ii) Solar Power (iii) Wind Power (iv) Bio-mass Power (v) Energy from waste (vi) Ocean energy, and (vii) Alternative fuel for surface transportation. Evolution of power transformer technology in the country during the past five decades is quite impressive. There are manufacturers in the country with full access to the latest technology at the global level. Some of the manufacturers have impressive R&D set up to support the technology. Renewable energy is very much promoted by the Chinese Government. At the same time as the law was passed, the Chinese Government set a target for renewable energy to contribute 10% of the country's gross energy consumption by 2020, a huge increase from the current 1%. It has been felt that there is rising demand for energy, food and raw materials by a population of 2.5 billion Chinese and Indians. Both these countries have large coal dominated energy systems in the world and the use of fossil fuels such as coal and oil releases carbon dioxide (CO2) into the air which adds to the greenhouse gases which lead to global warming.

Priority to renewable energies - on the amendment to the renewable energies act

International Nuclear Information System (INIS)

Heller, W.

2003-01-01

The Federal Ministry for the Environment, which has been the competent authority for renewable energies since the 2002 federal election, has presented draft legislation on the accelerated development of renewable energies in the electricity sector. This is to reduce, through internalization, the costs to the national economy arising from power supply, to conserve nature and the environment, avoid conflicts over fossil energy resources, and promote the advanced development of renewable energy technologies. Emphasis is put solely on protection of the climate and of the environment. The way towards sustainable energy supply by taking into account ecological, economic and social aspects is abandoned. The funding rates laid down in legislation are not going to offer major incentives for further plant improvement by technological development. The quantitative goals of this draft legislation onesidedly aimed at electricity production are doubtful. Renewable energies are hardly the right way to replace nuclear power plants operated in the baseload mode. What is missing in the draft legislation, though it would be urgently needed, is a clear time limit on the eligibility of renewable energy plants for subsidizing, as this would counteract the impression of permanent subsidizing.

To prepare for an urban influx of 2.5 billion people by 2050, it is critical to create cities that are low-carbon, resilient, and livable. Cities not only contribute to global climate change by emitting the majority of anthropogenic greenhouse gases but also are particularly vulnerable to the effects of climate change and extreme weather. We explore options for establishing sustainable energy systems by reducing energy consumption, particularly in the buildings and transportation sectors, and providing robust, decentralized, and renewable energy sources. Through technical advancements in power density, city-integrated renewable energy will be better suited to satisfy the high-energy demands of growing urban areas. Several economic, technical, behavioral, and political challenges need to be overcome for innovation to improve urban sustainability.

Renewable energies: public policy challenges

Grazi, Laure; Souletie, Arthur

Renewable energy sources (RES) are low-carbon energies available right within our borders, and as such can be of great value in addressing the challenges of climate change and energy security. In 2014, renewable energies accounted for 14.6% of France's gross final energy consumption. The French Energy Transition Act for Green Growth sets renewables targets of 23% and 32% as a share of gross final energy consumption by 2020 and 2030, respectively. However, renewable energies are still more costly than conventional energies. A significant share of this additional cost is borne by energy consumers, particularly in the form of energy taxation and biofuels blending obligations. Public aid is also provided to support heat production from renewable energy sources (RES-H). The two most significant aids available today are the Energy Transition Tax Credit (CITE) and the Heat Fund. Comparing the various types of renewable energies shows sharp disparities in terms of the cost of avoiding one tonne of CO 2 , which ranges from euros 59 to more than euros 500 for electricity production it follows that the cost of the energy transition is likely to vary significantly depending on which renewable energy sources are pushed to the fore. The combustion of biomass for heat production appears to offer an economically efficient way to reduce CO 2 emissions. Of the various renewable technologies available for the production of electricity (with the exception of hydropower, which was excluded from the scope of this study), onshore wind power is the least costly

This paper examines the causal relationship between CO{sub 2} emissions, nuclear energy consumption, renewable energy consumption, and economic growth for a group of 19 developed and developing countries for the period 1984-2007 using a panel error correction model. The long-run estimates indicate that there is a statistically significant negative association between nuclear energy consumption and emissions, but a statistically significant positive relationship between emissions and renewable energy consumption. The results from the panel Granger causality tests suggest that in the short-run nuclear energy consumption plays an important role in reducing CO{sub 2} emissions whereas renewable energy consumption does not contribute to reductions in emissions. This may be due to the lack of adequate storage technology to overcome intermittent supply problems as a result electricity producers have to rely on emission generating energy sources to meet peak load demand.

Limited fossil fuel resources and environmental impact of energy production technologies causing Global Warming have encouraged wide spread used of renewable energies. This article reviews the characteristics of renewable energy sources as well as their status within IR of Iran and pro-countries. According to the mentioned Information and Status, currently 22% of world electricity is produced through conversion of various renewable energies and expected to grow even further. This trend has been a main factor in reduction of end-used renewable energy prices. Consideration of social and environmental costs of fossil fuel use will help to reveal compatibility of renewable energies. Utilization of renewable energy potentials apart from proven environmental advantages and job creation effects may conserve country's conventional fossil fuel resources. In general, growth of renewable energy in a country is direct result of existing energy policies with respect to increasing the share of clean energies in the energy basket. Nevertheless in Iran yearly demand hikes for energy and considering the fact the fossil fuel reservoirs are limited, utilization of renewable energy potentials is inevitable

The evolution of renewable energy over the past decade has surpassed all expectations. Global installed capacity and production from all renewable technologies have increased substantially, and supporting policies have continued to spread to more countries in all regions of the world. Developments in the early 2000's showed upward trends in global renewable energy investment, capacity, and integration across all sectors, yet most mainstream projections did not predict the extraordinary expansion of renewables that was to unfold over the decade ahead. Several factors set the foundation for this rapid growth. The various energy crises-beginning in the 1970's - and the subsequent economic downturns underscored the role of energy for both national and economic security. At the same time, a handful of pioneering countries-such as Germany, Denmark, Spain, and the United States-created critical markets for renewables, which drove early technological advances and economies of scale, setting the stage and helping to fuel the past decade of explosive market expansion. Growing emphasis on mitigating climate change and adapting to its impacts has further contributed to the momentum. Renewable energy's contribution to the global heat, power and transport sectors has increased steadily. While growth in renewable's share of total energy use has been moderated by increases in both population and world energy demand-most notably in developing and emerging economies-renewable energy markets and technology developments have accelerated quickly, even when compared to other rapidly developing technologies such as mobile phones. Although the last decade has seen tremendous advances in the electricity sector, the renewable heating and cooling sector has lagged behind. This is despite the marked growth since 2004 in the use of geothermal, solar thermal, and biomass heating technologies for water and space heating, process heat, and cooling. Given that the share of

Majority of the power generation in India is carried out by conventional energy sources, coal and fossil fuels being the primary ones, which contribute heavily to greenhouse gas emission and global warming. The Indian power sector is witnessing a revolution as excitement grips the nation about harnessing electricity from various renewable energy sources. Electricity generation from renewable sources is increasingly recognized to play an important role for the achievement of a variety of primary and secondary energy policy goals, such as improved diversity and security of energy supply, reduction of local pollutant and global greenhouse gas emissions, regional and rural development, and exploitation of opportunities for fostering social cohesion, value addition and employment generation at the local and regional level. This focuses the solution of the energy crisis on judicious utilization of abundant the renewable energy resources, such as biomass, solar, wind, geothermal and ocean tidal energy. This paper reviews the renewable energy scenario of India as well as extrapolates the future developments keeping in view the consumption, production and supply of power. Research, development, production and demonstration have been carried out enthusiastically in India to find a feasible solution to the perennial problem of power shortage for the past three decades. India has obtained application of a variety of renewable energy technologies for use in different sectors too. There are ample opportunities with favorable geology and geography with huge customer base and widening gap between demand and supply. Technological advancement, suitable regulatory policies, tax rebates, efficiency improvement in consequence to R&D efforts are the few pathways to energy and environment conservation and it will ensure that these large, clean resource bases are exploited as quickly and cost effectively as possible. This paper gives an overview of the potential renewable energy resources

The renewable energy market in Australia

Australia is committed to an 8 per cent reduction in its emissions of greenhouse gases above 1990 levels as a result of the Kyoto Protocol for the period 2008-2012. At present, the emissions stand at 17.4 per cent above 1990 levels. Total electrical power in Australia resulting from renewable energy is in the order of 10.5 per cent. A mandatory renewable energy target of 9500 gigawatt hour (GWh) of extra renewable energy is to be produced annually by 2010, under the Renewable Energy (Electricity) Act. An emissions trading system has been implemented, involving one renewable energy certificate (REC) created for each megawatt hour of renewable energy generated. A significant expansion of the demand for renewable energy is expected in Australia over the next ten years, according to the Australian Greenhouse Office. Increased opportunities for local and international firms operating in the field of renewable energy are being created by the Australian government through initiatives such as the Renewable Energy Commercialization Program, and the Renewable Remote Power Generation Program. Solar, biomass, and wind power are comprised in the wealth of renewable energy resources in Australia. The market remains largely undeveloped. Firms from the United States and the European Union are the leading exporters of renewable energy technology to Australia. Public utilities and independent power producers having entered the deregulated electricity market are the consumers of renewable energy technology and services. A country with minimal duties in most cases, Australia has much in common with Canada, including similar regulatory and legal systems. Australia applies a 10 per cent goods and services tax, which would apply to Canadian exports. It was advised to consult the Australian Customs Service for additional information concerning duties that might be applicable to the renewable energy industry. 28 refs., 3 tabs

ACCELERATING THE ADOPTION PROCESS OF RENEWABLE ENERGY SOURCES AMONG SMES

Full Text Available By 2020, intermittent renewable small scale energy sources (e.g. wind and solar energy are expected to represent about 17% of the EU’s total electricity consumption. All national overriding energy policy objectives are to ensure competitive, secure and sustainable energy for the economy and for society. Renewable energy, allied with energy efficiency, is often found crucial to meet these goals of secure sustainable and competitive energy supplies reducing dependency on expensive fossil imports and underpinning the move towards a low carbon economy while delivering green jobs to the economy. This all contributes to national competitiveness and the jobs and economic growth agenda. However, a straight forward implementation of renewable energy options is not easy, due to various barriers and obstacles. For most SMEs, the concept of generating their own renewable energy is still more of academic than genuine interest. In general, several barriers are experienced, such as high capital investments, slow return on investment, and the lack of knowledge of the benefits. There is a need for education on the benefits and drawbacks of sustainable energy, as well as a greater contribution to costs for this to work. In this paper we describe the intermediate outcomes of a European Partnership under the name of GREAT (Growing Renewable Energy Applications and Technologies, funded under the INTERREG IVB NWE Programme. GREAT aims to encourage communities and small to medium size enterprises (SMEs in Ireland, the United Kingdon, Belgium and The Netherlands to develop technological solutions for Smart Grid, Renewable Energy and Distributive Generation; research and develop policy issues for regulatory authorities and provide structured co-operation opportunities between SMEs and research institutes / technology developers.

Does FDI influence renewable energy consumption? An analysis of sectoral FDI impact on renewable and non-renewable industrial energy consumption

International Nuclear Information System (INIS)

Doytch, Nadia; Narayan, Seema

2016-01-01

This study examines the link between foreign direct investment (FDI) and energy demand. FDI is a source of financing that allows businesses to grow. At the same time, FDI can be a source of innovation that promotes energy efficiency. Existing evidence on the impact of aggregate FDI inflows on energy consumption is scarce and inconclusive. In the current study, we disaggregate FDI inflows into mining, manufacturing, total services, and financial services components and examine the impact of these FDI flows on renewable – and non-renewable industrial energy – sources for 74 countries for the period 1985–2012. We employ a Blundell–Bond dynamic panel estimator to control for endogeneity and omitted variable biases in our panels. The results point broadly to an energy consumption-reducing effect with respect to non-renewable sources of energy and an energy consumption-augmenting effects with respect to renewable energy. We find that these effects vary in magnitude and significance by sectoral FDI. - Highlights: • FDI generally discourages the use of unclean energy. • Economic growth promotes non-renewable energy consumption. • Service FDI save energy and encourage the switch to renewable energy. • Mining FDI to low and lower middle-income panels save energy. • These results are mainly consistent with the FDI halo effect.

Renewables portfolio standard and regional energy structure optimisation in China

International Nuclear Information System (INIS)

Fan, J.; Sun, W.; Ren, D.-M.

2005-01-01

Eastern Coastal areas of China have been developing rapidly since the implementation of reforms and the opening of China's economic markets in 1978. As in most areas of the world, this rapid economic growth has been accompanied by large increases in energy consumption. China's coal-dominated energy structure has resulted in serious ecological and environmental problems. Exploiting renewable energy resources and introducing Renewables Portfolio Standard (RPS) are some of the most important approaches towards optimising and sustaining the energy structure of China. This paper discusses international experiences in the implementation of RPS policies and prospects for using these policies to encourage renewable energy development in China, establishes a concise definition of renewable resources, differentiating between the broad definition (which includes hydro over 25 MW in size) from the narrow definition (which limits the eligibility of hydro to below 25 MW in size), and quantitatively analyses the potential renewable energy target. The research shows that: (1) Under the narrow hydro definition the renewable energy target would be 5.1% and under the broad hydro definition it would be 18.4%. (2) Western China has contributed 90.2% of the total renewable electricity generation in the country (if big and medium hydropowers are not included). Including big and medium hydropower, the figure is 63.8%. (3) Eastern electricity companies can achieve their quota by buying Tradable Renewable Energy Certificates (TRCs or Green Certificates) and by exploiting renewable energy resources in Western China. The successful implementation of the RPS policy will achieve the goal of sharing the benefits and responsibilities of energy production between the different regions of China

Due to the increasing climate change, increasing dependence of imports from constant scarce fossil and nuclear energy resources and due to the strongly fluctuating energy prices, fundamental settings of the agenda for the power supply are placed at present in Germany and Europe. In the contribution under consideration, the Renewable Energy Research Association (Berlin, Federal Republic of Germany) recommends ways to the research and development of a power system in which renewable energies and energy efficiency play a central role. For the 6th energy research program of the Federal Government two principles can be derived: (a) The energy research must be intensified clearly and permanently; (b) In the energy research a clear stabilization of the renewable energies and the energy efficiency have to be performed, since they are the most important contributions to the future energy system.

Approximately 7 per cent of Prince Edward Island's (PEI) energy supply is from renewable sources, acquired mainly from biomass. Wind power accounts for 0.5 per cent of electricity production. This paper discussed issues concerning renewable energy developments in PEI, with particular reference to the PEI Renewable Energy Act as well as the PEI energy framework and renewable energy strategy, which was the result of public consultation sessions held in 2003. The results of these sessions indicated that greater development of indigenous renewable energy resources was desired, particularly in wind power. It was also stated that the government should help to advance renewable energy development in the province. Several development opportunities were highlighted, including: wind; biodiesel; ethanol; biomass; bio-gas; and small-scale hydro. The advantages of wind power were reviewed and wind data was presented. The economic and community benefits of renewable energy include local price stability, development opportunities, diversity of fuel type and security of supply. It was noted that renewable energy fully complemented the energy goals of the PEI government. Several strategies were discussed towards the development of renewable energy, including feasibility studies in biogas and biomass generation. The PEI government's commitment towards developing a regulatory framework acknowledging environmental sustainability was re-stated. Objectives include the promotion of renewable energy sources through the establishment of a Renewable Portfolio Standard for electricity; improvements in the economics of small-scale electricity production from renewable resources through the introduction of net metering; decreases in peak demand; enablement of green credits; the designation of areas for large-scale wind developments; and provision of guaranteed prices paid to producers for medium and large-scale renewable energy generators through feed-in tariffs. tabs, figs

Renewable energy projects are increasingly confronted by local opposition, which delays and sometimes even prevents their implementation. This reflects the frequent gap between support for the general idea of renewables as a strategy for reducing carbon emissions, and acceptance of renewable energy...... installations in the local landscape. A number of countries have introduced financial incentives to promote community acceptance. The tool box of incentives is still limited but in recent years it has been expanded to address local concerns. Certain general characteristics can be identified, suggesting...... that there are at least three distinct categories of incentives: individual compensation, community benefits and ownership measures. Local opposition must be approached with caution, as financial incentives to promote local acceptance can be seen as buying consent or even ‘bribery’, stirring up further opposition....

A future energy policy equally has to pursue environmental protection and climate protection, economic efficiency as well as supply security. Renewable energies substantially contribute to this. In the last decade, the Federal Government of Germany showed that a strong development of renewable energies is possible within a short time. For the year 2020, the industry prognosticates an amount of the renewable energies of 47% at the consumption of electricity, 25% at the heat consumption, and 22% at the fuel consumption in the traffic. The contribution under consideration shows that the surface which is needed for this is small. Depending upon climate, landscape, settlement structure and agrarian structure, each region offers its own different potentials.

The potential of renewable energies

If one compares the progress in research and development of renewable energy applications with the finding which has been granted to these activities during the 23 years after the first oil shock, one cannot but be very impressed. It is indicated in this paper hoe comprehensive the potential of renewable energy is. One should take into account that the methods described form a broad interdisciplinary field in contrast to fossil and nuclear technologies. From technical point of view the present and future energy demand can be met by the broad spectrum of renewable energies in combination with energy conservation. Many of these techniques are already economically competitive: solar architecture, wind energy, hydropower, low temperature heat production, photovoltaic for remote areas, various types of biomass application, geothermal energy although not exactly renewable. The future of renewable energies will depend on opening markets for these techniques

WIRE: Weather Intelligence for Renewable Energies

Renewable energies such as wind and solar energy will play an important, even decisive role in order to mitigate and adapt to the projected dramatic consequences to our society and environment due to climate change. Due to shrinking fossil resources, the transition to more and more renewable energy shares is unavoidable. But, as wind and solar energy are strongly dependent on highly variable weather processes, increased penetration rates will also lead to strong fluctuations in the electricity grid which need to be balanced. Proper and specific forecasting of ‘energy weather' is a key component for this. Therefore, it is today appropriate to scientifically address the requirements to provide the best possible specific weather information for forecasting the energy production of wind and solar power plants within the next minutes up to several days. Towards such aims, Weather Intelligence will first include developing dedicated post-processing algorithms coupled with weather prediction models and with past and/or online measurement data especially remote sensing observations. Second, it will contribute to investigate the difficult relationship between the highly intermittent weather dependent power production and concurrent capacities such as transport and distribution of this energy to the end users. Selecting, resp. developing surface-based and satellite remote sensing techniques well adapted to supply relevant information to the specific post-processing algorithms for solar and wind energy production short-term forecasts is a major task with big potential. It will lead to improved energy forecasts and help to increase the efficiency of the renewable energy productions while contributing to improve the management and presumably the design of the energy grids. The second goal will raise new challenges as this will require first from the energy producers and distributors definitions of the requested input data and new technologies dedicated to the management of

On 27 March 2013, the European Commission published its first Renewable Energy Progress Report under the framework of the 2009 Renewable Energy Directive. Since the adoption of this directive and the introduction of legally binding renewable energy targets, most Member States experienced significant growth in renewable energy consumption. 2010 figures indicate that the EU as a whole is on its trajectory towards the 2020 targets with a renewable energy share of 12.7%. Moreover, in 2010 the majority of Member States already reached their 2011/2012 interim targets set in the Directive. However, as the trajectory grows steeper towards the end, more efforts will still be needed from the Member States in order to reach the 2020 targets. With regard to the EU biofuels and bioliquids sustainability criteria, Member States' implementation of the biofuels scheme is considered too slow. In accordance with the reporting requirements set out in the 2009 Directive on Renewable Energy, every two years the European Commission publishes a Renewable Energy Progress Report. The report assesses Member States' progress in the promotion and use of renewable energy along the trajectory towards the 2020 renewable energy targets. The report also describes the overall renewable energy policy developments in each Member State and their compliance with the measures outlined in the Directive and the National Renewable Energy Action Plans. Moreover, in accordance with the Directive, it reports on the sustainability of biofuels and bioliquids consumed in the EU and the impacts of this consumption. A consortium led by Ecofys was contracted by the European Commission to perform support activities concerning the assessment of progress in renewable energy and sustainability of biofuels.

Renewable energies for power generation

Freris, L.; Infield, D.

Power generation from renewable energy sources is different from power generation from classical energies (nuclear, thermal..). Therefore, the integration into the grid of the electricity supplied by renewable sources requires a deep thinking. The reason is that these power sources are controlled by variable elements, like wind, water and sun, which condition production. This book deals with the following aspects in detail: characteristics of classical and intermittent generators; grid balancing between supply and demand; conversion methods of renewable energies into electricity; power systems; privatizing of power generation and birth of new markets, in particular the 'green' power market; development of renewable energies thanks to technical advances. It gives a comprehensive overview of the present day available renewable energy sources for power generation. (J.S.)

Several forms of renewable energy compete for supremacy or for an appropriate role in global energy supply. A form of renewable energy can only play an important role in global energy supply if it fulfills several basic requirements. Its capacity must allow supplying a considerable fraction of present and future energy demand, all materials for its production must be readily available, land demand must not be prohibitive, and prices must reach grid parity in the nearer future. Moreover, a renewable energy technology can only be acceptable if it is politically safe. We supply a collection of indicators which allow assessing competing forms of renewable energy and elucidate why surprise is still a major factor in this field, calling for adaptive management. Photovoltaics (PV) are used as an example of a renewable energy source that looks highly promising, possibly supplemented by solar thermal electricity production (ST). We also show why energy use will contribute to land use problems and discuss ways in which the right choice of renewables may be indispensible in solving these problems.

Renewable energy policy. Into the mainstream

International Nuclear Information System (INIS)

2003-01-01

Renewable energy today is at a critical stage of development: renewable technologies are maturing, and costs for some technologies are in the competitive range. Beyond the energy they produce, renewable energy technologies offer a variety of other benefits towards the achievement of sustainable development goals. This promise has led to all IEA governments to support their greater development. But, while renewables markets are growing strongly, additional steps must be taken to accelerate the achievement of sustainable, large-scale markets. This report by the IEA's Renewable Energy Working Party outlines those steps, and the benefits of moving renewable energy into the mainstream

The County of Somerset, New Jersey, through the Somerset County Improvement Authority (SCIA), applied Federal funding through the U.S. Department of Energy to will apply project funds to buy-down the capital costs of equipment associated with the installation of solar photovoltaic (PV) systems at two sites owned by the County. This Renewable Energy Initiative allows the County to take advantage of clean renewable energy, without any adverse debt impacts, and at a price that results in operating budget savings beyond what is presently available in the marketplace. This project addressed the objectives of the Office of Energy Efficiency and Renewable Energy by making the acquisition of renewable energy more affordable for the County, thereby, encouraging other counties and local units to develop similar programs and increase the deployment of solar energy technologies. The two sites that were funded by the DOE grant are part of a much larger, ambitious, and unique renewable energy project, described in the next section.

On market integration of renewable energies

Since the liberalization of electricity and gas markets in Europe, the energy sector has changed in every respect with one constant: most actors have underestimated renewable energies with regard to their growth, their economies of scale and their impact on existing energy markets. If that trend continues, the urgency for policy measures will increase. Given the security of supply, integration of renewables into energy markets is necessary to replace fossil and nuclear capacities. However, the further development of renewable energies plays a crucial role in the ability to meet the energy and climate policy targets. Thus, it increases the need for regulation to achieve societally desirable outcomes. This thesis has examined the effects of renewable energies on existing energy markets. It has also investigated the various other cost-efficient options that policy makers have in striving to reach energy and climate policy targets. We assumed that cost efficiency is a relevant side condition. In the past, this has not always been the case. Today, cost efficiency is definitely relevant and might also be an essential target in the future (see Bundesregierung 2013, p. 50). We contributed to the analysis of power prices as a result of increasing shares of renewables by showing that shutting down conventional capacities will have a merit order effect. This is necessary if renewable energies are to replace fossil and nuclear capacities. Any discussion of a change of market design should make mention of this effect, since spot market revenues impact a company's behaviour within potential capacity markets. From a consumer perspective, we have shown that there is a substantial need for secured capacity with low marginal costs to keep spot prices stable. This outcome has important implications for policy makers if they are to provide consumers with low-cost renewable market integration. Policy makers have numerous ways to reach policy targets than rapidly expanding

When renewable energy met sustainable growth. Regulation, cost reduction, and the rise of renewable energy in the United States

International Nuclear Information System (INIS)

Stephens, Samantha

2016-01-01

Historically and famously fossil-fuel dependent, the U.S. energy and electricity mixes are evolving quickly as costs fall for renewables, regulations mandate their implementation, and fiscal policy incentivizes their installation. The investment and production tax credits (ITC and PTC) as well as power purchase agreements (PPAs) are well-known for their contributions to the development of solar and wind capacity, and the recent extensions of these credits has led to a positive outlook for continued growth in installations and generation. In addition, the green power market is experiencing record participation, as tracking the positive environmental externalities of renewable power has become important to meet renewable portfolio standards, which mandate implementation of renewable energy by state. Cost reduction is further taking place globally due to technological advances and economies of scale, which serves as another key driver for development. Of course, challenges are still present, particularly due to a plentiful and inexpensive domestic fossil fuel supply, uneven application of regulation and incentives state-by-state, and the uncertainty of continued political support. Even so, a progressive lowering of traditional barriers is leading to the potential for widespread deployment of renewables across the American landscape. (author)

A potential of utilizing renewable energy sources and the state support in Slovakia

Directory of Open Access Journals (Sweden)

Lívia Bodonská

2007-04-01

Full Text Available The renewable energy sources are domestic sources of energy that help to enhance the safety of energy supplies and the diversification of energy sources. The utilization of such sources complies with the environmental acceptability requirement and leads to a reduction in greenhouse gas emissions. The renewable energy is proved to be commercially viable for a growing list of consumers and uses. The renewable energy technologies provide many benefits that go well beyond the energy alone. More and more, the renewable energies contribute to the three pillars of the sustainable development in the economy, environment and the society.Several renewable energy technologies are established in world markets, building global industries and infrastructures. Other renewables become competitive in growing markets, and some are widely recognised as the lowest cost option for stand-alone and offgrid applications. An increased utilization of renewable energy sources in the heat and electricity generation is one of priority tasks of the Slovak Republic to boost the use of domestic energy potential and thus to decrease the Slovakia’s dependence on imported fossil fuels.

Renewable Energy in China

Full Text Available China is the most densely populated country in the world with high rate of economic growth resulting in higher demand for energy resources and in strive to guarantee stable supply of these resources. Chinese annual GDP growth in 2012 and 2013 was down to 7.7% comparing to 10% in 2000-2011 [7]. In 2012 and 2013 economic growth stumbled because of slowdown in manufacturing and exports, taking into account that Chinese government was eager to cut inflation and excessive investments in some segments of the market. Speaking about energy sector Chinese government is aimed at promotion of market-based pricing systems, activities for advanced energy efficiency and higher competition between energy companies, and increased investment in renewable energy resources. Considering renewables as one of many ways to diversify energy supplies, lower dependence on coal and improve environmental situation Chinese government actively supports and develops programs aimed at support of renewable energy industry in China. Chinese economic development is tightly attached to five-year plans. It seems important to mention the fact that main energy goals for current 12-th "five-year plan" are to achieve 15% renewables consumption and CO2 sequestration up to 40-45% by2020 in order to lower dependency on coal and improve environmental situation. As a result of Chinese state policy to develop renewables China achieved certain results in wind energy, helioenergetics, hydroenergetics and energy from waste recycling.

Renewable Energy Sources - Technologies and Development of the Economy

The usage of renewable energy sources is a substitute for usage of fossil fuels, whose quantities are limited, and it represents an essential contribution to the reduction of greenhouse gases; at the same time it has a great economic significance for the development of new industries and creation of new jobs. To speed up gradual transition from fossil to renewable sources, governments of all EU member states harmonise their legislations and subordinate regulations promoting investments in usage of renewable sources and thus creating opportunities for new jobs especially in the production of plants and equipment for utilisation of wind power, solar energy, small hydro power plants, biomass and other kinds of renewable sources. In the last 10 years Croatia has adopted a number of acts and regulations that also stimulate investors to utilise renewable sources, and the source of such subsidies is a higher price of electricity paid by all the consumers. On the other hand, the development of domestic industry and gaining references necessary for gaining new contracts are very difficult because of stiff international competition and foreign sources of finance, which often require purchase of foreign equipment as a condition for contract award. In such conditions the utilisation of renewable sources does not contribute either to economic development or creating new jobs in Croatia, but in the countries in which such equipment is produced.(author).

Modeling renewable energy company risk

International Nuclear Information System (INIS)

Sadorsky, Perry

2012-01-01

The renewable energy sector is one of the fastest growing components of the energy industry and along with this increased demand for renewable energy there has been an increase in investing and financing activities. The tradeoff between risk and return in the renewable energy sector is, however, precarious. Renewable energy companies are often among the riskiest types of companies to invest in and for this reason it is necessary to have a good understanding of the risk factors. This paper uses a variable beta model to investigate the determinants of renewable energy company risk. The empirical results show that company sales growth has a negative impact on company risk while oil price increases have a positive impact on company risk. When oil price returns are positive and moderate, increases in sales growth can offset the impact of oil price returns and this leads to lower systematic risk.

Contrary to popular belief, renewables primarily biomass and hydropower currently supply about 20% of the world's energy. Biomass alone meets 35% of developing countries total energy needs, though often not in a manner that is renewable or sustainable in the long term. Steady advances have been made since the mid-seventies in an array of new energy technologies that will be needed if the world is to greatly increase its reliance on renewable resources. Indeed many of the machines and processes that could provide energy in a renewable energy based economy are now almost economically competitive with fossil fuels. Further cost reductions are expected in the next decade, as these technologies continue to improve through R and D efforts. After a period of neglected in the eighties, many governments are now supporting new energy technologies more effectively, which may signal the beginning of a renewable energy boom in the years ahead.

2011-07-01

This information paper accompanies the IEA publication Deploying Renewables 2011: Best and Future Policy Practice (IEA, 2011a). It provides more detailed data and analysis on policies for Deploying Renewables, and is intended to complement the main publication. It provides an account of the strategic drivers underpinning renewable energy (RE) technology deployment (energy security, economic development and environment protection) and assesses RE technologies with respect to these drivers, including an estimate of GHG emissions reductions due to RE technologies. The paper also explores the different barriers to deploying renewables at a given stage of market maturity and discusses what tools policy makers can avail of to succeed in removing deployment barriers. An additional topical highlight explores the challenges associated with accelerating the diffusion of RE technologies in developing countries.

Despite various policies, renewable energy resources have not been developed in Malaysia. This study investigates the factors that influence renewable energy technology acceptance in Peninsular Malaysia and attempts to show the impact of cost and knowledge on the perceived ease of use and perceived usefulness of renewable energy technology. The results show that cost of renewable energy has an indirect effect on attitudes towards using renewable energy through the associated impact on the perceived ease of use and perceived usefulness. The results also indicate that public knowledge in Peninsular Malaysia does not affect perceived ease of use, although the positive impact of knowledge on perceived usefulness is supported. Furthermore, our results show that the current business environment in Peninsular Malaysia does not support the adoption of renewable energy technology, and thus, renewable energy technology is not commercially viable in Peninsular Malaysia. Additionally, the population of Peninsular Malaysia associates the use of renewable energy with a high level of effort and therefore has a negative attitude towards the use of renewable energy technology. There is, therefore, a definite need to pay more attention to the role of public perception and awareness in the successes and failures of renewable energy policy. - Highlights: • Public acceptance is an essential element in the diffusion of renewable energy. • Perceived ease of use and perceived usefulness affect intention to use renewables. • It is important to reduce the cost of renewable energy, particularly for end users. • Renewable energy policies should address issues of public perception and awareness.

International entrepreneurship within offshore renewable energy

The climate is changing, the worlds known fossil energy reserves are limited, and most economies are struggling to get out of a financial crisis. The UNs Intergovernmental Panel on Climate Change calls for new technologies, rapid commercialization, and rapid international diffusion as important tools to mitigate the climate change (IPCC 2007). Nations all over the world have allocated large funds to facilitate the development of renewable energy technologies and markets to secure the future supply of energy and to sustain economic growth (REN21 2009). Use of fossil fuel is the main source of humans contribution to global warming. At the same time, fossil fuel is probably the most important resource for economic development on a global scale (IEA 2009). With this as a backdrop, the objective of this PhD thesis is to investigate how technology-based companies act to commercialize and internationally diffuse technologies that may produce abundant clean, renewable energy. More specifically, I have assessed the emerging offshore renewable energy industries (offshore wind, wave, and tidal energy) as case industries to make the International Entrepreneurship literature more relevant for the current situation. The findings reveal extensive international activities at both the company level and industry level, even in phases in which the firms have yet to commercialize and industries have yet to enter the growth phase. These findings demand significant updates to theoretical models and convey several recommendations to mangers, investors, and policy makers. Managers should be aware of and master the new opportunities/threats identified. For investors, the findings provide implications for their valuation of new ventures. For policy makers, the findings open up a new landscape of political threats and opportunities as the battle to attract promising industries has begun earlier than previously prescribed.

Trends in renewable energy strategy development and the role of CDM in Bangladesh

International Nuclear Information System (INIS)

Noim Uddin, Sk; Taplin, Ros

2009-01-01

This article analyses and discusses trends in renewable energy strategy development in Bangladesh and the prospective role of the clean development mechanism (CDM) under the Kyoto Protocol. Use of renewables for electricity generation results in less greenhouse gas emissions compared with fossil fuel energy systems and often offers additional synergistic benefits. Despite the large potential for development of renewable energy sources in Bangladesh, currently their contribution to electricity generation remains insignificant. Existing policies and programs on renewable energy in Bangladesh are reviewed in relation to the specific requirements needed for CDM. A number of barriers are identified that impede the implementation of the CDM mechanism. Overall, it is recommended that more appropriate energy strategies, including a new national renewable energy strategy, need to be formulated and implemented and more suitable institutional settings need to be provided to promote energy sustainability for Bangladesh. Also, the suggestion is made that incorporation of objectives for CDM promotion in the new national renewable energy strategy to tie in with Bangladesh's CDM strategy should assist in advancement of renewables

Technology policy and sustainable development: the case of renewable energy

International Nuclear Information System (INIS)

Wohlgemuth, N.

2000-01-01

Policies to address long-term energy concerns include a wide range of initiatives. Taxes can internalise costs; financial mechanisms, including subsidies, can target particularly favourable but otherwise non-competitive investments; regulation can apply standards to raise performance of appliances; information programmes can improve decision making; and R and D can make available new options. The 1987 report of the World Commission on Environment and development, found that 'energy efficiency can only buy for the world to develop 'low-energy-paths' based on renewable sources...'. Although many renewable energy systems are in a relatively early stage of development, they offer the world 'a potentially huge primary energy source, sustainable in perpetuity and available in various forms to every nation on Earth.' It suggested that an R and D programme of renewable energy is required to attain the same level of primary energy that is now obtained from a mix of fossil, nuclear, and renewable energy resources. Since renewable energy contributes to all dimensions of sustainable development, one policy challenge is to ensure that renewable energy has a fair opportunity to complete with other resources required for the provision of energy services, especially on 'liberalised' energy markets. This paper gives an overview of rationales for government intervention in energy-related R and D, and international energy R and D trends. it concludes that the liberalisation of energy markets has an overall negative impact on private sector investments in energy R and D and that without a sustained and diverse programme of energy R and D and implementation, we are crippling our ability to make the necessary improvements in the global energy system, especially in light of sustainable development requirements.

Simsek, Hayal Ayca; Simsek, Nevzat

2013-01-01

Recently, the importance of renewable energy sources has increased significantly as climate change has become an important long term threat to global ecosystems and the world economy. In the face of increased concern about climate change and high fossil fuel costs together with a reduction in the primary energy sources such as oil, natural gas and coal, alternative energy sources (renewables) are increasingly needed to respond to the threat of climate change and growing energy demand in the world. Recent developments in Turkey, such as the liberalization of the electricity market and improvements in the renewable legislations, have accelerated the growth process and investment opportunities in the field of renewable energy. Turkey′s naturally endowed potential for renewables, such as solar, geothermal and wind, also accompanied these developments and attracted world attention to this market. In Turkey, renewable energy sources have gained great importance in the last decades due to growing energy demand and incentive policies which foster the utilization of renewable energy sources. This study aims to explore the availability and potential of renewable energy sources in Turkey and discuss the government policies and economic aspects. - highlights: • Turkey′s potential for renewable energy has attracted world attention. • Turkey has specific energy objectives in promoting renewable energy. • This paper evaluates recent incentives for renewable energy in Turkey. • Incentives in Turkey have led to more investment in renewable energy generation

Optimal Energy Mix with Renewable Portfolio Standards in Korea

Directory of Open Access Journals (Sweden)

Zong Woo Geem

2016-05-01

Full Text Available Korea is a heavily energy-dependent country whose primary energy consumption ranks ninth in the world. However, at the same time, it promised to reduce carbon emission and planned to use more renewable energy. Thus, the objective of this study is to propose an optimal energy mix planning model in electricity generation from various energy sources, such as gas, coal, nuclear, hydro, wind, photovoltaic, and biomass, which considers more renewable and sustainable portions by imposing governmental regulation named renewable portfolio standard (RPS. This optimization model minimizes various costs such as construction cost, operation and management cost, fuel cost, and carbon emission cost while satisfying minimal demand requirement, maximal annual installation potential, and renewable portfolio standard constraints. Results showed that this optimization model could successfully generate energy mix plan from 2012 to 2030 while minimizing the objective costs and satisfying all the constraints. Therefore, this optimization model contributes more efficient and objective method to the complex decision-making process with a sustainability option. This proposed energy mix model is expected to be applied not only to Korea, but also to many other countries in the future for more economical planning of their electricity generation while affecting climate change less.

Who formulates renewable-energy policy? A Swedish example

International Nuclear Information System (INIS)

Uba, Katrin

2010-01-01

A broad participation by stakeholders and an extensive reliance on expert advice are often seen as preconditions for a legitimate and successfully implemented renewable energy policy. However, we have lacked systematic data for testing this argument. This article's contribution is to examine the actors who take part in the making of Swedish energy policy with the help of data on the composition of various committees of inquiry over the last twenty years (1988-2009). Swedish renewable energy policy is often characterised with words like 'pioneering' and 'forerunner', suggesting that the policy-making process in this area engages many different experts and stakeholders. Our data give only some support to this argument. Results point to a noteworthy predominance of politicians, civil servants, and representatives of state agencies within the policy-process. Producers of uranium and fossils based energy have been engaged more often than producers of renewable energy. Experts have played a prominent role, but this is mostly due to the participation of expert bureaucrats rather than of scientists. The study suggests that a better understanding of the making of energy policy, both in Sweden and elsewhere, requires greater attention to the networks and role of various state employees.

Renewable energy islands in Europe

Energy Technology Data Exchange (ETDEWEB)

Oestergaard, Iben [ed.

1998-12-31

This publication includes a compiled presentation of various aspects concerning the possible transformation of some European islands into renewable energy communities and these projects were presented by a selection of pioneer islands at the first European Seminar on Renewable Energy Islands, held on the Danish island of Samsoee, 29-30 June 1998. This issue has increased in importance with the presentation of the ambitious EU-White Paper: `Energy for the future: Renewable Sources of Energy` which was adopted in 1998. One of the key elements of the strategy for an accelerated implementation of renewable energy is to transform 100 localities within Europe into communities which are to be 100% self-sufficient with renewable energy before 2010. In line with this strategy, the Danish Government appointed the island of Samsoe towards the end of 1997 to be the first `official` Danish, renewable energy island. This is to serve as a demonstration project for other local communities, both in Denmark as well as in the rest Europe. Gothland, Madeira, Canary Islands, Cape Verde, Arki, Crete, Minorca and Orkney Islands were represented. Environmental advantages of wind, solar and wave power for distant island communities were indicated. Serious savings would be achieved by limitation of fossil fuel import and utilization of local resources. (EG)

Renewable energy - an attractive marketing proposition

2001-01-01

The Global Utilities arm of international business consultants PriceWaterhouseCoopers (PWC) has provided a unique insight into the investment plans of Australian utilities regarding renewable energy. PWC has released the findings of a survey of electricity generators and retailers that neatly illustrates the risks and opportunities facing corporations liable under the mandatory renewable energy targets (MRET). Probably the most revealing finding of the PWC report- 'The Future of Australian Renewable Energy' was that the majority of respondents have not yet formulated a comprehensive renewable energy strategy aimed at meeting their obligations under MRET, or maximising the benefit of renewable energy certificates (RECs) produced. Notably, the majority of those surveyed believed that the strongest incentives for investing in new renewable energy generation was the company's 'green image'. In contrast investment characteristics such as low risk returns, the achievement of cost efficiencies or attractive revenue streams were not critical reasons for investing in renewable generation

Renewable energy rebound effect?: Estimating the impact of state renewable energy financial incentives on residential electricity consumption

Science.gov (United States)

Stephenson, Beth A.

Climate change is a well-documented phenomenon. If left unchecked greenhouse gas emissions will continue global surface warming, likely leading to severe and irreversible impacts. Generating renewable energy has become an increasingly salient topic in energy policy as it may mitigate the impact of climate change. State renewable energy financial incentives have been in place since the mid-1970s in some states and over 40 states have adopted one or more incentives at some point since then. Using multivariate linear and fixed effects regression for the years 2002 through 2012, I estimate the relationship between state renewable energy financial incentives and residential electricity consumption, along with the associated policy implications. My hypothesis is that a renewable energy rebound effect is present; therefore, states with renewable energy financial incentives have a higher rate of residential electricity consumption. I find a renewable energy rebound effect is present in varying degrees for each model, but the results do not definitively indicate how particular incentives influence consumer behavior. States should use caution when adopting and keeping renewable energy financial incentives as this may increase consumption in the short-term. The long-term impact is unclear, making it worthwhile for policymakers to continue studying the potential for renewable energy financial incentives to alter consumer behavior.

The potentials of biomass as renewable energy

International Nuclear Information System (INIS)

Edens, J.J.

1994-01-01

Biomass is a term used in the context of energy to define a range of products derived from photosynthesis. Annually large amounts of solar energy is stored in the leaves, stems and branches of plants. Of the various renewable sources of energy, biomass is thus unique in that it represents stored solar energy. In addition it is the only source of carbon, and it may be converted into convenient solid, liquid and gaseous fuels. Biomass, principally in the form of wood, is humankind's oldest form of energy, and has been used to fuel both domestic and industrial activities. Traditional use has been, through direct combustion, a process still used extensively in many parts of the world. Biomass is a renewable and indigenous resource that requires little or no foreign exchange. But it is a dispersed, labor-intensive and land requiring source of energy and may avoid or reduce problems of waste disposal. We'll try to assess the potential contribution of biomass to the future world energy supply. 4 refs., 6 tabs

New and renewable energies. Stakes, driving forces and perspectives of the renewable energies market

International Nuclear Information System (INIS)

2000-09-01

New and renewable energies (hydro-power, wind-power, solar, biomass, biogas, geothermal and fuel cells) are progressively entering the industrialization phase (except for hydro-power which is already largely developed). Thus they are no more considered as solutions for utopian ecologists but have reached the status of alternative technologies. This study takes stock of the following questions: what are the applications of renewable energies, what is their stage of development and their potential with respect to fossil fuels, what are their perspectives of development, and what are the strategies developed by the actors of the sector? The main stakes of the renewable energy sector are: fulfilling the increasing power needs (in particular with the wind and solar power in isolated areas), improving the competitiveness (reduction of the investment costs), developing financial incentives (tax relief, financial helps, eco-taxes..), participating to the reduction of pollutant emissions. The renewable energy sector is progressively structuring and profits by the increasing implication of major energy actors, such as the oil companies. The behaviour and strategy of 14 major actors of the renewable energy sector is also analyzed. (J.S.)

A regional-scale assessment of local renewable energy resources in Cumbria, UK

International Nuclear Information System (INIS)

Gormally, A.M.; Whyatt, J.D.; Timmis, R.J.; Pooley, C.G.

2012-01-01

There is increasing focus on the role small-scale decentralised renewable energy developments could play in helping the UK meet its target of over 15% renewable energy by the year 2020 and alter energy behaviours through active community engagement. Upland areas are considered key areas where such community-based developments could occur due to their natural resources and range of community scales. This study uses GIS-based techniques to develop a methodology that assesses the regional-scale potential for community-based renewable electricity across Cumbria and whether a combination of these developments at the community-scale could make a significant contribution to local electricity consumption. This methodology looks at a range of technologies including hydro-power, wind-power, solar PV and bioenergy. The results suggest there is ample resource available for small communities by combining a mix of localised renewable electricity developments, which is highlighted through energy scenarios for a selected community. Further work will investigate whether this potential can be realised in reality by looking at resource resilience and community-level acceptability. - Highlights: ► A mix of wind, solar, bioenergy and hydro-power options are presented for Cumbria, UK. ► High resolution spatial analysis is conducted focussing on localised developments. ► Locations with sufficient renewable electricity potential were identified. ► Renewable options are explored further through a town case study. ► Scenarios consider different scales, mixes and contributions to local energy demand.

Evaluating the landscape impact of renewable energy plants

Science.gov (United States)

Ioannidis, Romanos; Koutsoyiannis, Demetris

2017-04-01

Different types of renewable energy have been on an ongoing competition with each other. There has been a lot of research comparing the most common types of renewable energy plants in relation with their efficiency, cost and environmental impact. However, few papers so far have attempted to analyse their impact on landscape and there has never been in depth research on which type of renewable energy causes the least impact on the natural, cultural and aesthetic characteristics of a landscape. This seems to be a significant omission given the vast areas of land already covered with renewable energy plants and the worldwide plans for many more renewable energy projects in the future. Meanwhile, the low aesthetic quality of renewable energy plants has already been an obstacle to their further development, with several relevant examples from countries such as Spain and the Netherlands. There have even been cases where aesthetic degradation is the primary or even the single argument of the opposition to proposed plants. In any case, the aesthetic design and the integration of renewable energy plants into the landscape should really be important design parameters if we plan those projects to truly be sustainable and to be considered complete works of engineering. To initiate dialogue over those aspects of renewable energy, we provide a first comparison on hydro, solar and wind energy. To materialize this comparison, we use data from existing dams, photovoltaic and wind farms. Initially, the average area per MW covered by each type of energy plant is calculated and then evaluated qualitatively from a landscape-impact perspective. Although the area affected is comparable in these three cases, the analysis of the data suggests that dams offer a considerable amount of advantages compared to the other two types of plants. This conclusion arises from the fact that dams, whose basic impact to the landscape is the creation of an artificial lake, contribute much less to the

Evaluating investments in renewable energy under policy risks

International Nuclear Information System (INIS)

Gatzert, Nadine; Vogl, Nikolai

2016-01-01

The considerable amount of required infrastructure and renewable energy investments expected in the forthcoming years also implies an increasingly relevant contribution of private and institutional investors. In this context, especially regulatory and policy risks have been shown to play a major role for investors when evaluating investments in renewable energy and should thus also be taken into account in risk assessment and when deriving risk-return profiles. In this paper, we provide a stochastic model framework to quantify policy risks associated with renewable energy investments (e.g. a retrospective reduction of a feed-in tariff), thereby also taking into account energy price risk, resource risk, and inflation risk. The model is illustrated by means of simulations and scenario analyses, and it makes use of expert estimates and fuzzy set theory for quantifying policy risks. Our numerical results for a portfolio of onshore wind farms in Germany and France show that policy risk can strongly impact risk-return profiles, and that cross-country diversification effects can considerably decrease the overall risk for investors. - Highlights: •Quantification of policy risks associated with renewable energy investments. •Results emphasize that policy risk has a major impact on risk and return. •Study of the cross-country diversification potential. •Cross-country diversification can considerably decrease the risk for an investor.

Which leadership for renewable energies?

International Nuclear Information System (INIS)

Chaumien, Marielle

2016-02-01

This publication first outlines that France is late in deploying renewable energies by 2020. It comments the application of the Energy multi-year plan (PPE), evokes the content of a report by the French Court of Auditors about costs and means of implementation of transition (with notably the issue of maintenance of nuclear plants). It also shows that European Union is not a leader in renewable energies any more, that some European countries are changing sides, that figures and trends must be carefully compared with those in the field of fossil and nuclear energies, that all energies are not all the same, that jobs and system integration are also important, that investments and attractiveness of countries in renewable energies must be assessed, and that a mobilisation on small scale and consumer-based renewable energies is required. Ten recommendations are made for France to support the EU leadership development

Nuclear energy and its synergies with renewable energies

International Nuclear Information System (INIS)

Carre, F.; Mermilliod, N.; Devezeaux De Lavergne, J.G.; Durand, S.

2011-01-01

France has the ambition to become a world leader in both nuclear industry and in renewable energies. 3 types of synergies between nuclear power and renewable energies are highlighted. First, nuclear power can be used as a low-carbon energy to produce the equipment required to renewable energy production for instance photovoltaic cells. Secondly, to benefit from the complementary features of both energies: continuous/intermittency of the production, centralized/local production. The future development of smart grids will help to do that. Thirdly, to use nuclear energy to produce massively hydrogen from water and synthetic fuels from biomass. (A.C.)

The integration of renewable energies into the electricity systems of North Africa

International Nuclear Information System (INIS)

Brand, Bernhard

2015-01-01

How can renewable energy sources be efficiently integrated into the North African electricity systems? By using techno-economic modeling methods, this book explores optimized electricity system expansion pathways until the year 2030 for the five North African countries - Morocco, Algeria, Tunisia, Libya and Egypt. The results indicate that renewable energy integration is actually a viable business case for the entire region, if wind and solar capacities are properly planned in conjunction with the conventional generation system and under consideration of the country-specific electricity supply-/demand patterns. Further aspects featured in this publication are the impact of renewable power on the transnational electricity transmission system and the question how decision making processes about renewable energy strategies can be improved in the North African context. The book is a contribution to the scientific literature about energy issues in the Middle East and North Africa (MENA), but also seeks to address political and industrial practitioners concerned with the development of the region's renewable energy future.

The Office of Energy Efficiency and Renewable Energy (EE) is part of the U.S. Department of Energy that is specifically charged with encouraging the more efficient use of energy resources, and the use of renewable energy resources - such as solar power, wind power, biomass energy and geothermal energy. In the past several years, EE has increased its emphasis on technology deployment through partnerships with states, local governments and private companies. Partnerships move new discoveries more quickly into the marketplace, where they can create jobs, prevent pollution, save resources, and produce many other benefits. The author then emphasizes the importance of this effort in a number of different sections of the paper: energy consumption pervades everything we do; U.S. energy imports are rising to record levels; transportation energy demand is increasing; U.S. energy use is increasing; population growth increases world energy demand; total costs of energy consumption aren`t always counted; world energy markets offer incredible potential; cost of renewables is decreasing; clean energy is essential to sustainable development; sustainable energy policy; sustainable energy initiatives: utilities, buildings, and transportation.

Subsidies for renewable energy?

International Nuclear Information System (INIS)

Skytte, K.; Grenaa Jensen, S.; Morthorst, P.E.; Olsen, O.J.

2004-01-01

Ambitious Danish and European energy and environment objectives make a point of using renewable energy sources in the electricity supply. Denmark has been leading country in successful development and commercialization of wind turbines and is as yet one of the leading manufacturers of the world. Danish governments have successfully invested a lot in this development. Other countries have spent more money without achieving a similar success. The questions are why things have gone so well in Denmark and if the Danish success can be repeated for other renewable energy technologies. The starting point of this book is that a political decision on subsidizing the developmental process of a specific technology not in itself guarantees that the technology will turn out reliable and efficient enough to compete successfully in a liberalized electricity market. An understanding of this development is necessary in order to affect a technological development. This book goes through the development of different renewable energy technologies and two theories used for discussing the technological development: experience curves and innovation theory. Based on the discussions and a description of causal relations, an analytical model for different phases of renewable energy technologies' developmental progress and technological life cycle is made. The model is used for evaluating the subsidies for chosen renewable technologies in Denmark. With wind energy as example an analysis of what went well or badly, what might be done and which actions might be efficient is made. (BA)

Renewable energy costs, potentials, barriers: Conceptual issues

Renewable energy can become the major energy supply option in low-carbon energy economies. Disruptive transformations in all energy systems are necessary for tapping widely available renewable energy resources. Organizing the energy transition from non-sustainable to renewable energy is often described as the major challenge of the first half of the 21st century. Technological innovation, the economy (costs and prices) and policies have to be aligned to achieve full renewable energy potentials, and barriers impeding that growth need to be removed. These issues are also covered by IPCC's special report on renewable energy and climate change to be completed in 2010. This article focuses on the interrelations among the drivers. It clarifies definitions of costs and prices, and of barriers. After reviewing how the third and fourth assessment reports of IPCC cover mitigation potentials and commenting on definitions of renewable energy potentials in the literature, we propose a consistent set of potentials of renewable energy supplies.

The US Army Corps of Engineers has retained Idaho National Laboratory (INL) to conduct a study of past INL experiences and complete a report that identifies the processes that are needed for the development of renewable energy projects on government properties. The INL has always maintained expertise in power systems and applied engineering and INL’s renewable energy experiences date back to the 1980’s when our engineers began performing US Air Force wind energy feasibility studies and development projects. Over the last 20+ years of working with Department of Defense and other government agencies to study, design, and build government renewable projects, INL has experienced the do’s and don’ts for being successful with a project. These compiled guidelines for government renewable energy projects could include wind, hydro, geothermal, solar, biomass, or a variety of hybrid systems; however, for the purpose of narrowing the focus of this report, wind projects are the main topic discussed throughout this report. It is our thought that a lot of what is discussed could be applied, possibly with some modifications, to other areas of renewable energy. It is also important to note that individual projects (regardless the type) vary to some degree depending on location, size, and need but in general these concepts and directions can be carried over to the majority of government renewable energy projects. This report focuses on the initial development that needs to occur for any project to be a successful government renewable energy project.

Renewable energies heat act and government grants in Germany

International Nuclear Information System (INIS)

Nast, M.

2010-01-01

In Germany renewable energies in the heat market are promoted by the Renewable Energies Heat Act (EEWaermeG) and by government grants. Ultimately, these two instruments are not only about short-term market success, but rather about the perspectives of climate protection and resource conservation. The focus of this report is therefore on the long-term significance of the current design of government grants and EEWaermeG. We will introduce and discuss the quantitative goals and structural changes strived for as well as - on a slightly shorter time horizon - the quality assurance regulations which must accompany the steady and stable growth of renewable energies. In the process, we will elaborate in particular on heat pumps, which have recently been added to the government support programme, along with solar collectors. Some explanations regarding the structural relationships between EEWaermeG and government grants round off this contribution. (author)

Along with high-speed economic development and increasing energy consumption, the Chinese Government faces a growing pressure to maintain the balance between energy supply and demand. In 2009, China has become both the largest energy consumer and CO 2 emitting country in the world. In this case, the inappropriate energy consumption structure should be changed. As an alternative, a suitable infrastructure for the implementation of renewable energy may serve as a long-term sustainable solution. The perspective of a 100% renewable energy system has been analyzed and discussed in some countries previously. In this process, assessment of domestic renewable energy sources is the first step. Then appropriate methodologies are needed to perform energy system analyses involving the integration of more sustainable strategies. Denmark may serve as an example of how sustainable strategies can be implemented. The Danish system has demonstrated the possibility of converting into a 100% renewable energy system. This paper discusses the perspective of renewable energy in China firstly, and then analyses whether it is suitable to adopt similar methodologies applied in other countries as China approaches a renewable energy system. The conclusion is that China's domestic renewable energy sources are abundant and show the possibility to cover future energy demand; the methodologies used to analyse a 100% renewable energy system are applicable in China. Therefore, proposing an analysis of a 100% renewable energy system in China is not unreasonable. (author)

It shows the rapid growth and informs on the importance of renewable energy sources for climate protection. The new CDU/FDP government headed by Angela Merkel stressed its intention to develop the potential of renewable energy sources. Apart from the effect of higher energy efficiency, this will also help Germany to make an ambitious contribution to climate protection world-wide. Renewable energy sources are to provide the biggest share of power supply in the future. By 2020, the EEG (German Renewables Act) envisages at least a 30 percent share for renewable energy sources as an intermediate goal. In the field of heat supply, at least 14 percent are envisaged fro 2020. (orig./RHM)

Renewables Global Futures Report: Great debates towards 100% renewable energy

International Nuclear Information System (INIS)

Teske, Sven; Fattal, Alex; Lins, Christine; Hullin, Martin; Williamson, Laura E.

2017-01-01

The first version of REN21's Renewables Global Futures Report (GFR) published in January 2013 identified a panorama of likely future debates related to the renewable energy transition. As a reflection of the wide range of contemporary thinking by the many experts interviewed for the report, it did not present just one vision of the future but rather a 'mosaic' of insights. Given the positive feedback in response to the first edition, a new edition has been prepared, continuing where the last one left off. The objective of this report is to gather opinions about the feasibility of a 100% renewable energy future, and the macro-economic impacts it would entail. In so doing, the report reflects on the debates of 2013, and tracks their evolution to the present time. Some remain, some have changed, some have been overtaken by progress, and new ones have arisen. They are summarised here as the Great Debates in renewable energy. The questionnaire for the survey was developed in close cooperation between the REN21 Secretariat, the Institute for Sustainable Future (ISF) of the University of Technology Sydney/Australia (UTS) and the Institute for Advanced Sustainability Studies (IASS) in Potsdam/Germany. It covered the following topics: 1. How much renewables?; 2. Power sector; 3. Heating and cooling; 4. Transport; 5. Storage; 6. Demand-side management and energy efficiency; 7. Integration of sectors; 8. Macro-economic considerations; 9. Technology and costs; 10. Policy; 11. Cities; 12. Distributed renewable energy/energy access; 13. Barriers/challenges/enablers. 114 experts were interviewed in total; the average interview time was approximately one hour. The interviews were conducted between May and October 2016. The questionnaire was also mirrored in an online version and used both by interviewers and interviewees to record the interview process. Interviewees were selected from the following regions: Africa, Australia and Oceania, China, Europe, India, Japan, Latin America

The impacts of non-renewable and renewable energy on CO2 emissions in Turkey.

Science.gov (United States)

Bulut, Umit

2017-06-01

As a result of great increases in CO 2 emissions in the last few decades, many papers have examined the relationship between renewable energy and CO 2 emissions in the energy economics literature, because as a clean energy source, renewable energy can reduce CO 2 emissions and solve environmental problems stemming from increases in CO 2 emissions. When one analyses these papers, he/she will observe that they employ fixed parameter estimation methods, and time-varying effects of non-renewable and renewable energy consumption/production on greenhouse gas emissions are ignored. In order to fulfil this gap in the literature, this paper examines the effects of non-renewable and renewable energy on CO 2 emissions in Turkey over the period 1970-2013 by employing fixed parameter and time-varying parameter estimation methods. Estimation methods reveal that CO 2 emissions are positively related to non-renewable energy and renewable energy in Turkey. Since policy makers expect renewable energy to decrease CO 2 emissions, this paper argues that renewable energy is not able to satisfy the expectations of policy makers though fewer CO 2 emissions arise through production of electricity using renewable sources. In conclusion, the paper argues that policy makers should implement long-term energy policies in Turkey.

Renewable Energy Policy Fact sheet - Estonia

International Nuclear Information System (INIS)

2017-09-01

The EurObserv'ER policy profiles give a snapshot of the renewable energy policy in the EU Member States. Electricity from renewable sources is mainly promoted through feed-in premiums (FiP). In addition, investment subsidies are available for biogas/biomass-based RES-E and wind power installations. Renewable heat is stimulated through investment subsidies to CHP plants generating renewable heat and electricity, as well as subsidies for private heat consumers. Renewable transport fuels are currently mainly incentivised by way of a support scheme to promote the purchase of electric cars that use power produced from renewable energy sources. Recently, a measure for supporting bio-methane in the transport sector has been adopted. Generally, a number of investment subsidy schemes are in place to promote the development, installation and use of renewable energy production installations. However, certain subsidy conditions still have to be announced and implemented. The total amount of financial support to be allocated to renewable energy and energy efficiency related projects during period 2014-2020 will be over euro 490 million. The current administratively determined FiP scheme is set to be replaced by an auction-based scheme within short

These proceedings present some European testimonies about the advantage of local investment, illustrated with concrete cases taken in Germany, Denmark and Switzerland. They demonstrate that local investment in renewable energy sources is a reality and that this practice has indisputably contributed to their significant development in some countries of the European Union. The sustain of foreign banks to the financing of renewable energy sources is at the evidence an example to follow up in countries like France, Greece or Spain. Important efforts have to be made to simplify and encourage the implementation of projects, in particular from the administrative point of view. Beyond the financial aspects, the colloquium has shown that these practices of citizenship involvement represent an important factor of social adaptation and acceptation. The projects, gathering local actors but also the overall citizens through common investment funds, ensure a better territorial anchoring and a sustain to local and sustainable development. This document has been published with the support of the European Commission and ADEME (French Agency for Environment and Energy Management). (J.S.)

The thematics presented have been about: development of smart grids and design of electrical energy production systems that allow money saving and reducing emissions to the environment; studies on the use of non-traditional plants and agricultural waste; sustainable energy model in the process of coffee production; experiments from biomass for the fabrication of biodiesel, biogas production and storage; and the use of non-conventional energy. Researches were presented at the Renewable Energy Symposium, organized by the Centro de Investigacion en Estructuras Microscopicas and support of the Vicerrectoria de Investigacion, both from the Universidad de Costa Rica [es

Renewable energies in the EU

On January 23, 2008, the European Commission presented proposals in the form of a directive in an effort to give more specific shape to the objective adopted in the spring, i.e. to increase to 20% by 2020 the share of renewable energies in energy consumption in the Community. The proposal was to include legally binding goals for the overall share of renewable energy sources and the share of biofuels in the transport sector. The proposed directive on 'promoting the use of energy from renewable sources' calls upon each member state to ensure that its share of energy from renewable sources in the total energy consumption in 2020 at least corresponds to the target mentioned in Annex I Part A. In addition to the targets, the EU Commission charted a tentative course towards a minimum increase in the share of renewable energies in the period between 2011 and 2020. Finally, the member states are obliged to adopt national action plans. Unfortunately, the EU is missing an important target in its proposed directive: It should establish a framework for harmonized conditions promoting the use of renewable energies. One aspect to be welcomed is the introduction of a system of certificates of origin. It represents the entry, in principle, into a trading system with certificates of origin. The Green Package incorporates a wealth of new approaches. They will have to be tested and, if necessary, supplemented. Something else is evident, however: The directive established the foundations of a vast number of new regulations and red tape. (orig.)

Willingness to pay for electricity from renewable energy

National polls reveal widespread public preference and willingness to pay more for renewables. ``Green pricing`` programs attempt to capitalize on these preferences and on an expressed willingness to pay more for environmental protection. This report explores the utility option of green pricing as a method of aggregating public preferences for renewables. It summarizes national data on public preferences for renewables and willingness to pay (WTP) for electricity from renewable energy sources; examines utility market studies on WTP for renewables and green-pricing program features; critiques utility market research on green pricing; and discusses experiences with selected green-pricing programs. The report draws inferences for program design and future research. Given the limited experiences with the programs so far, the evidence suggests that programs in which customers pay a monthly premium for a specific renewable electricity product elicit a higher monthly financial commitment per customer than programs asking for contributions to unspecified future actions involving renewables. The experience with green-pricing programs is summarized and factors likely to affect customer participation are identified.

Full Text Available The Energy-CSOP facilitates broad equity participation of citizens without assets or savings in a regulated public energy utility. As the CSOP is designed for regulated markets with guaranteed prices, regulated market access and long-term relationships between producer and consumer, the energy market is predestined. A CSOP trust can be set up for a renewable energy plant (e.g., a biogas reactor, a solar panel, a windmill or a geothermic drill. European states have set an ambitious target to reach 20% share of energy from renewable sources by 2020. Germany as Europe’s green energy leader could become a pioneer in CSOP implementation. Small communities in Europe would benefit from the increased share of renewable energy resources.

Reserves of our major energy sources natural gas, petroleum and coal are limited. Their combustion essentially contributes to air pollution widh all its health hazards and environmental impacts. Apart from the fact that power plants supplying energy with the help of nuclear fission are disputed, uranium reserves are limited, too. The developmental state of nuclear fusion, an the other hand, still defies concrete statements as the future availability of fusion-based energy. Considering above facts it is evident that renewable energy sources will be gaining in importance. The book above all intends to give a consistent survey on the forms and capacities of renewable energy sources, existing technologies and technologies currently being developed, historical aspects, the social and environmental compatibility of renewable energy sources, economic aspects, and future prospects. The dictionary contains 197 independent alphabetically arranged and basically coherent chapters which are to provide the basis for profound reflections on the subject.

Renewable energy consumption has been identified as a potential solution to the intermittent power supply in Ghana. Recently, a Renewable Energy Act has been passed which has a target of 10% of renewable energy component in Ghana's energy mix by 2020. Whilst effort is been made to enhance supply through feed in tariffs, education and tax reduction on renewable energy related equipment, there is the need to understand the drivers of renewable energy demand. In this study, the general unrestricted model through Autometrics is used to estimate the determinants of renewable energy demand in Ghana. The results indicate that both economic factors and non-economic affect the demand for renewable energy. In addition, the underlying energy demand trend exhibits energy using behaviour. The study recommends that economic factors such as consumer subsidies should be considered when promoting renewable energy demand.
