  1. 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.

    This paper analyzes China's policy approach to renewable energies and assesses how effectively China has met the ideal of appropriate interactions between renewable energy policy and renewable energy industrial policy. First we briefly discuss the interactions between these two policies. Then we outline China's key renewable energy and renewable industrial policies and find that China's government has well recognized the need for this policy interaction. After that, we study the achievements and problems in China's wind and solar PV sector during 2005–2012 and argue that China's policy approach to renewable energies has placed priority first on developing a renewable energy manufacturing industry and only second on renewable energy itself, and it has not effectively met the ideal of appropriate interactions between renewable energy policy and renewable energy industrial policy. Lastly, we make an in-depth analysis of the three ideas underlying this policy approach, that is, the green development idea, the low-carbon leadership idea and indigenous innovation idea. We conclude that Chinas' policy approach to renewable energies needs to enhance the interactions between renewable energy policy and renewable energy industrial policy. The paper contributes to a deeper understanding of China's policy strategy toward renewable energies. -- Highlights: •Interactions between renewable energy policy and renewable energy industrial policy are discussed. •China's key renewable energy and renewable energy industrial policies are outlined. •Two empirical cases illustrate China's policy approach to renewable energies. •We argue that China needs to enhance the interactions between the two policies. •Three ideas underlie China's policy approach to renewable energies

  5. Is renewable energy effective in promoting growth?

    International Nuclear Information System (INIS)

    Marques, António Cardoso; Fuinhas, José Alberto

    2012-01-01

    This paper applies panel data techniques to analyze the role of the various energy sources in economic growth, for a set of 24 European countries (1990–2007), controlling for energy consumption and energy dependency. The results suggest that the negative effect of the use of renewables supplants the positive effect of creating income by exploiting a natural resource locally, and thus growth does not appear to improve with the change towards renewables. The high costs of promoting renewables are probably being placed excessively upon the economy, namely by increasing the costs of electricity tariffs, thus inducing a deceleration in economic activity. Fossil fuels lead to dissimilar effects on growth while natural gas does not appear to be relevant in explaining growth. Coal hampers the capacity for growth, whereas the use of oil stimulates that growth. This is in line with productive structures that are deeply grounded in fossil fuels, particularly oil. - Highlights: ► We empirically test the distinct effects of decomposing energy by source on growth. ► We focus on 24 European Countries (1990–1907) by applying a panel data approach. ► Fossil fuels lead to dissimilar effects on growth. Coal hampers and oil stimulates it. ► Economic growth does not appear to improve with the paradigm change to renewable. ► High costs of promotion of renewables are being placed excessively upon the economy.

  6. Employment effects of the extended use of renewable energies

    Any investment has a positive effect on employment: setting up an investment object involves a number of jobs. But in national economic terms, investments into renewable energies have an employment effect only if the investments are viewed within the context of the energy system as a whole. A global scenario for extending the use of renewable energies as it is outlined by the group 2010 is expected to have a positive effect on employment. Employment effects in connection with renewable energies are inferior to those associated with investments that are economical ex ante, such as many investments for enhancing energy efficiency.

    Over the last decade Germany has boosted renewable energy in power production by means of massive subsidies. The flip side are very high electricity prices which raises concerns that the transition cost towards a renewable energy system will be mainly borne by poor households. In this paper, we combine computable general equilibrium and microsimulation analysis to investigate the cost-effectiveness and incidence of Germany's renewable energy promotion. We find that the regressive effects of renewable energy promotion could be ameliorated by alternative subsidy financing mechanisms which achieve the same level of electricity generation from renewable energy sources.

    Renewable portfolio standards (RPSs) and mandates to invest in cost-effective energy efficiency (EE) are increasingly popular policy tools to combat climate change and dependence on fossil fuels. These supply-side and demand-side policies, however, are often uncoordinated. Using California as a case in point, this paper demonstrates that states could improve resource allocation if these two policies were coordinated by incorporating renewable-energy procurement cost into the cost-effectiveness determination for EE investment. In particular, if renewable energy is relatively expensive when compared to conventional energy, increasing the RPS target raises the cost-effective level of EE investment

    Koutstaal, P.; Bijlsma, M.; Zwart, G.; Van Tilburg, X.; Ozdemir, O.

    2009-08-01

    A renewable obligation (RO) combined with tradable renewable energy certificates is a market-based instrument used to promote the production of electricity from renewable energy sources. A renewable obligation is an alternative for subsidies. A renewable obligation will only be an efficient instrument if certificate markets are efficient. This requires that there is no market power and no anti-competitive behaviour on the certificate market. If the current developments in Dutch renewable energy production continue, market power on a future renewable certificate market in the Netherlands will probably not be an issue, even if the RO should only rest on the retail market instead of on the whole electricity market. A renewable obligation will raise the retail price for consumers, thereby reducing consumer surplus. Simulations show that the retail electricity price increases with 30 euro per MWh to a level of 104 euro per MWh in case of a 30% renewable target. Consumer surplus is reduced with 19% compared to the baseline scenario. In contrast, a subsidy such as the Dutch SDE (Promoting Renewable Energy scheme or 'Stimulering Duurzame Energie') which is financed from the state budget has the effect to (slightly) lower the retail electricity price, thereby increasing consumer surplus. It should however be realised that the costs of the subsidy will indirectly affect electricity consumers through their tax payments.

    2013-09-15

    The Renewal Energies Act has so far been one of the cornerstones of the energy revolution. As a result of the Act the production of electricity from renewable sources has been considerably increased. As the most expensive forms of renewable energies have grown fastest, average costs have not shrunk but have risen significantly. The ongoing growth led to increasing subsidies for renewable energies and growing costs for electricity consumers in business and private households. It would be insufficient to look at absolute cost developments only, as distribution effects may be critical. As electricity consumption only slightly depends on household income, higher income leads to lower significance of electricity costs. Therefore, low income households bear a relatively higher burden of costs for renewable energies. Furthermore, wealthy households could benefit from the subsidies as they can invest in renewable energy systems.

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

    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.

    The Energy Committee of the Royal Swedish Academy of Sciences has in a series of projects gathered information and knowledge on renewable energy from various sources, both within and outside the academic world. In this article, we synthesize and summarize some of the main points on renewable energy from the various Energy Committee projects and the Committee's Energy 2050 symposium, regarding energy from water and wind, bioenergy, and solar energy. We further summarize the Energy Committee's scenario estimates of future renewable energy contributions to the global energy system, and other presentations given at the Energy 2050 symposium. In general, international coordination and investment in energy research and development is crucial to enable future reliance on renewable energy sources with minimal fossil fuel use.

    2011-01-01

    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.

  18. Improving cost-effectiveness and mitigating risks of renewable energy requirements

    Science.gov (United States)

    Griffin, James P.

    Policy makers at the federal and state levels of government are debating actions to reduce U.S. greenhouse gas emissions and dependence on oil as an energy source. Several concerns drive this debate: sharp rises in energy prices, increasing unease about the risks of climate change, energy security, and interest in expanding the domestic renewable energy industry. Renewable energy requirements are frequently proposed to address these concerns, and are currently in place, in various forms, at the federal and state levels of government. These policies specify that a certain portion of the energy supply come from renewable energy sources. This dissertation focuses on a specific proposal, known as 25 X 25, which requires 25% of electricity and motor vehicle transportation fuels supplied to U.S. consumers to come from renewable energy sources, such as wind power and ethanol, by 2025. This dissertation builds on prior energy policy analysis, and more specifically analyses of renewable energy requirements, by assessing the social welfare implications of a 25 x 25 policy and applying new methods of uncertainty analysis to multiple policy options decision makers can use to implement the policy. These methods identify policy options that can improve the cost-effectiveness and reduce the risks of renewable energy requirements. While the dissertation focuses on a specific policy, the research methods and findings are applicable to other renewable energy requirement policies. In the dissertation, I analyze six strategies for implementing a 25 x 25 policy across several hundred scenarios that represent plausible futures for uncertainties in energy markets, such as renewable energy costs, energy demand, and fossil fuel prices. The strategies vary in the availability of resources that qualify towards the policy requirement and the use of a "safety valve" that allows refiners and utilities to pay a constant fee after renewable energy costs reach a predetermined threshold.

    2006-01-01

    The promotion of electricity produced from renewable energy is a high priority of the European Union, as well of its member states. The German government wants to increase the share of renewable energies from about 5% to 12% by 2010. To attain this goal, the German government has introduced compulsory compensation schemes for electricity produced from renewable energy fed into the public grid. This paper examines the economic impact of this policy employing an econometric model. Particular emphasis was given to employment effects. In general, we distinguish two effects: (1) an expansive effect resulting from additional investments and (2) a contractive effect resulting from an increase in the production cost of power. The first effect will dominate during the first years and lead to an increase in employment of approximately 33,000 new jobs. However, the contractive effect will offset these gains and lead to a slightly negative employment balance by 2010

    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 North Carolina Solar Center at NC State University, in collaboration with the National Renewable Energy Laboratory, examined 10 state financial-incentive programs in six states using a case-study approach in order to clarify the key factors-both internal and external to the program-that influence their effectiveness at stimulating deployment of renewable energy technologies. While existing information resources such as the National Database of State Incentives for Renewable Energy (DSIRE, www.dsireusa.org) have documented what incentive programs are available, the effectiveness of such programs is not well understood. Understanding the impact of current financial incentives on the deployment of renewables and the factors that influence their effectiveness is critical to a variety of stakeholders, particularly in states considering new incentives or interested in improving or discarding existing ones.

    1998-01-01

    The Optimal Renewable Energy Model (OREM) has been developed to determine the optimum level of renewable energy sources utilisation in India for the year 2020-21. The model aims at minimising cost/efficiency ratio and determines the optimum allocation of different renewable energy sources for various end-uses. The extent of social acceptance level, potential limit, demand and reliability will decide the renewable energy distribution pattern and are hence used as constraints in the model. In this paper, the performance and reliability of wind energy system and its effects on OREM model has been analysed. The demonstration windfarm (4 MW) which is situated in Muppandal, a village in the southern part of India, has been selected for the study. The windfarm has 20 wind turbine machines of 200 KW capacity . The average technical availability, real availability and capacity factor have been analysed from 1991 to 1995 and they are found to be 94.1%, 76.4% and 25.5% respectively. The reliability factor of wind energy systems is found to be 0.5 at 10,000 hours. The OREM model is analysed considering the above said factors for wind energy system, solar energy system and biomass energy systems. The model selects wind energy for pumping end-use to an extent of 0.3153 x10 15 KJ. (Author)

    Renewable energy facilities have been installed in many regions, because of their possibility to be an alternative to fossil fuels for mitigating global warming. Besides the profitability of renewable energy businesses, indirect economic effects of installing renewable energy facilities should be clarified. This study examines the possibility that the renewable energy facilities give renewed impetus to regional economic progress. The economic effects are analysed with input-output techniques in a rural area in Japan. As a consequence, both positive and negative effects on the rural economy are derived. In addition, we will focus on the changes in sectors such as construction, business services, banking, etc. as a result of economic activities for renewable systems. The business benefits of renewable energy system are discussed. (author)

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

    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.

    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.

This includes a correct pricing policy of renewable energy sources with respect to nuclear energy and fossil fuel. The latter energy sources have been favoured in the past. In addition, an open market policy, the restructuring or conversion of existing international energy institutes, and international treaties for the protection of the natural environment are needed in view of achieving the zero carbon dioxide emission objective.

    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)

    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.

    Energy efficiency and renewable energy are considered to be two indispensable solutions to control GHG (greenhouse gas) emissions. Moreover, industrialization is at the center of discussions on the roles of countries to reduce CO 2 emissions. However, the literature is underprovided to understand the long run contribution of energy efficiency, renewable energy and industrial composition in reducing GHG emissions at the macro level. In this study, we differentiate the effects of economic activity, energy efficiency, economic structure and use of renewable energy resources on CO 2 emissions. We develop energy efficiency indices for thirty six countries for the period of 1971–2009 and use a CCE (common correlated effects) estimator model that is consistent under heterogeneity and cross-sectional dependence. We find a positive significant effect of energy efficiency on CO 2 emissions in the long-run. Similarly, substituting renewable energy for non-renewable energy reduces CO 2 emissions in the long-run. Our results ensure widely discussed roles of energy efficiency and renewable energy in curbing CO 2 emissions. Furthermore, the scale of economic activity measured by real income and industrialization have significant positive effect on CO 2 emissions. - Highlights: • We model long-run effects of energy efficiency and renewable energy on CO 2 . • Energy efficiency significantly reduces CO 2 emissions over the long term. • Replacing non-renewable energy sources with renewable ones reduces CO 2 emissions. • CO 2 emissions rise with increases in real income. • Industrial composition affects CO 2 emissions

    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.

  7. Energy Systems With Renewable Hydrogen Compared to Direct Use of Renewable Energy in Austria

    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

    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

  13. U.S. state policies for renewable energy: Context and effectiveness

    International Nuclear Information System (INIS)

    Delmas, Magali A.; Montes-Sancho, Maria J.

    2011-01-01

    Over the past decade, state policies on renewable energy have been on the rise in the U.S., providing states with various options for encouraging the generation of renewable electricity. Two promising policies, the Renewable Portfolio Standard (RPS) and the Mandatory Green Power Option (MGPO), have been implemented in many states but the evidence about their effectiveness is mixed. In this paper, we argue that recognizing the natural, social, and policy context under which MGPO and RPS are adopted is necessary in order to measure their true effectiveness. This is because the context rather than the policy might lead to positive outcomes and there is the possibility for sample bias. When controlling for the context in which the policies are implemented, we find that RPS has a negative impact on investments in renewable capacity. However, we find that investor-owned utilities seem to respond more positively to RPS mandates than publicly owned utilities. By contrast, MGPO appears to have a significant effect on installed renewable capacity for all utilities regardless of the context in which it is implemented. - Research highlights: → We assess whether U.S. state renewable policies are effective at generating investments in renewable capacity. → We find that Renewable Portfolio Standard (RPS) is ineffective. → We find that Mandatory Green Power Option (MGPO) is effective. → Investor-owned utilities respond more positively to RPS than publicly owned utilities. → The results differ from previous studies because we control for sample bias.

    This paper investigates empirically the effect of market regulation and renewable energy policies on innovation activity in different renewable energy technologies. For the EU countries and the years 1980 to 2007, we built a unique dataset containing information on patent production in eight different technologies, proxies of market regulation and technology-specific renewable energy policies. Our main finding is that, compared to privatisation and unbundling, reducing entry barriers is a more significant driver of renewable energy innovation, but that its effect varies across technologies and is stronger in technologies characterised by potential entry of small, independent power producers. In addition, the inducement effect of renewable energy policies is heterogeneous and more pronounced for wind, which is the only technology that is mature and has high technological potential. Finally, ratification of the Kyoto protocol, which determined a more stable and less uncertain policy framework, amplifies the inducement effect of both energy policy and market liberalisation. - Highlights: • We study the effect of market regulation and energy policy on renewable technologies. • Reducing entry barriers is a significant driver of renewable energy innovation. • The Kyoto protocol amplifies the effect of both energy policy and liberalisation. • These effects are heterogeneous across technologies and stronger for wind.

    2009-01-01

    Europe's increasing demand for energy and its environmental preoccupations are creating a favourable environment for the development of renewable energy sources. This article stated that although many European countries have adopted voluntary policies since the 1990s to increase the use of renewable energy sources, they have not been developed in an equal or consistent manner. A table was included to show the consumption of renewable energies by country; the percentage of renewable energies in 1995 as compared to 2006; and the consumption of primary energy resources. Combined, Germany, Spain and Denmark produce 75 per cent of wind energy in Europe, while 75 per cent of Europe's hydroelectricity is produced in Norway, Sweden, France, Italy, Austria and Switzerland. Germany has also made significant contributions in developing biomass energy. The article emphasized that the development of renewable energy sources is limited by the fact that it cannot keep up with growing energy demands. In addition, renewable energies cannot yet replace all fossil fuel consumption in Europe because of the variation in development from one country to another. 1 ref., 2 tabs., 4 figs.

  18. Nuclear Energy and Renewables interaction: System Effects in Low-carbon Electricity Systems

    International Nuclear Information System (INIS)

    Keppler, Jan Horst; Cometto, Marco

    2013-01-01

    This report presents a synthesis of the OECD/NEA study 'Nuclear Energy and Renewables: System Effects in Low-carbon Electricity Systems'. It addresses the increasingly important interactions of variable renewables and dispatchable energy technologies, such as nuclear power, in terms of their effects on electricity systems. These effects add costs to the production of electricity, which are not usually transparent. The report recommends that decision-makers should take into account such system costs and internalise them according to a 'generator pays' principle, which is currently not the case. Analysing data from six OECD/NEA countries, the study finds that including the system costs of variable renewables at the level of the electricity grid increases the total costs of electricity supply by up to one-third, depending on technology, country and penetration levels. In addition, it concludes that, unless the current market subsidies for renewables are altered, dispatchable technologies will increasingly not be replaced as they reach their end of life and consequently security of supply will suffer. This implies that significant changes in management and cost allocation will be needed to generate the flexibility required for an economically viable coexistence of nuclear energy and renewables in increasingly de-carbonised electricity systems

    Full Text Available As renewable energy requirements increases, its relation with development is controversial. In this study, by taking human development index for development level, the relationship between renewable electricity net generation values and development has been searched with panel analysis. Study covers two different time periods: 1980-2010 with 5 year data to analyze long term effects and 2005-2010 yearly data for short term effects. Unlike previous studies, energy generation has been taken into consideration for it is thought to be more related with economic development. It is found that in the long run economic development will be leading to renewable energy production, while in the short run there exists a bidirectional causal relationship between renewable energy production and economic development. In addition, the causal relationship between economic development and renewable energy production varies both in the long run and in the short run due to human development level of the countries.

    With several mid-term policies in place to support the development of renewables, the European Union (EU) seems on its way to increasing the share of renewable energy to the targeted 12% by the year 2010. It is however, yet unclear how effective these policies are, which technologies will see the largest growth and which countries will indeed be able to meet their targets. This article discusses a monitoring protocol that was developed to monitor this effectiveness and judge whether targets will be met. In a step-wise approach policy instruments are characterised and analysed, leading to a quantitative assessment of the likely growth in renewable energy production for each individual technology and country in case no policy changes occur. Applying this monitoring protocol at the EU-level we show that with the current policies in place renewable energy production will reach a share of 8-10% in 2010, and the share of electricity production will reach a level of 15-18% of total electricity consumption, whereas the target is 22.5%. Additional policies are clearly needed to achieve the ambitious targets set.

    With several mid-term policies in place to support the development of renewables, the European Union (EU) seems on its way to increasing the share of renewable energy to the targeted 12% by the year 2010. It is however, yet unclear how effective these policies are, which technologies will see the largest growth and which countries will indeed be able to meet their targets. This article discusses a monitoring protocol that was developed to monitor this effectiveness and judge whether targets will be met. In a step-wise approach policy instruments are characterised and analysed, leading to a quantitative assessment of the likely growth in renewable energy production for each individual technology and country in case no policy changes occur. Applying this monitoring protocol at the EU-level we show that with the current policies in place renewable energy production will reach a share of 8-10% in 2010, and the share of electricity production will reach a level of 15-18% of total electricity consumption, whereas the target is 22.5%. Additional policies are clearly needed to achieve the ambitious targets set

  13. Growth and renewable energy in Europe: A random effect model with evidence for neutrality hypothesis

    2011-01-01

    This is an empirical study on the causal relationship between economic growth and renewable energy for 27 European countries in a multivariate panel framework over the period 1997-2007 using a random effect model and including final energy consumption, greenhouse gas emissions and employment as additional independent variables in the model. Empirical results do not confirm causality between renewable energy consumption and GDP, although panel causality tests unfold short-run relationships between renewable energy and greenhouse gas emissions and employment. The estimated cointegration factor refrains from unity, indicating only a weak, if any, relationship between economic growth and renewable energy consumption in Europe, suggesting evidence of the neutrality hypothesis, which can partly be explained by the uneven and insufficient exploitation of renewable energy sources across Europe.

    The energy transition and thus turning away from fossil fuels and nuclear energy sources is based on an increased expansion of renewable energies. This expansion mainly take place in nature and the landscape, which conflicts with the objectives of the Federal Nature Conservation Act concerning scenery or the consequences of monoculture cultivation of energy crops. What happens, however, if more than one type of renewables occur compressed in a landscape that is investigated in this work. Result from cumulative effects are extended conflict with the objectives of the Federal Nature Conservation Act or possibly have positive effects can be seen? A ''cumulative effect'' is defined as an additive-synergistic overall effect of all a protected interest of respective impact factors. These arise from one or more projects / plans and influence from a variety of ways. As part of the investigations carried out it is clear that extended conflicts may arise in relation to the objectives of the Federal Nature Conservation Act by cumulative effects of renewable energies. To prevent these conflicts, policies and regulations in the context of spatial planning is necessary to enable a focusing of spatial planning for a sustainable expansion of renewable energy. [de

    Reviews and an analysis of the policy support for the stimulation of renewable electricity in the current energy market are presented, and an overview is given of the main new developments influencing the renewable energy market. The report is part of the analysis phase of the project REMAC 2000, which has led to the publication of a roadmap for the acceleration of the RE market. REMAC 2000 aims to promote a sustainable growth of the renewable energy market. For such a sustainable growth, important success factors are not only effectiveness of policy, but also security for investors, which is essential for building up a sector and developing the renewable energy market. Consistency of regulations and policies at different levels and between policy fields form a condition for security, as does the active involvement of market stakeholders. Further, the increasing role of trade within the energy and renewable energy sector leads to a priority for international coherence of policies and markets. To guarantee a sustainable growth of the renewable energy sector, a broad perspective of policy makers and planners is required- to include a long time frame, a comprehensive view of related policy fields and authorities involved, and an orientation that looks beyond national borders

    Utilization of renewable energy sources and the application of environmentally sound energy technologies are essential to sustainable development and will help to secure the quality of living and the well-being of the future generations. Turkey presently has considerable renewable energy sources. The most important renewable sources are hydropower, wind, solar, geothermal, and biomass. The use of renewable energy as a topic to study energy and its forms permits a novel way to motivate students, particularly those who energy topics taking conscience with the environment. This paper presents the analysis and classification of renewable energy sources and how to find out their origin and a way to motivate students in energy topics related to renewable sources and also, the development of didactic competencies in special blended learning arrangements for educationalists, trainers and lecturers in adult education in the field of renewable energies in Turkey.

    2013-07-01

    We investigate the effect of energy liberalizations on policies that support renewable energy in a long panel of OECD countries. We estimate this effect accounting for the endogeneity of liberalisation related to joint decisions within a country's energy strategy. Using regulation in other industries as instruments, we find that energy liberalisation increases the public support to renewable energy. The effect of liberalisation is the second largest after the effect of per-capita income and is fully driven by reductions in entry barriers, while the effect of privatisation is negative. Finally, our results are robust to dynamic specifications and various policy indicators. (authors)

    2008-01-01

    This article analyzes the effects of renewable energy on GDP for 116 economies in 2003 through Structural Equation Modeling (SEM) approach. In order to decipher the mechanism of how the use of renewables improves macroeconomic efficiency, we decompose GDP by the 'expenditure approach'. Although previous theory predicts positive effects of renewables on capital formation and trade balance, the SEM results show that renewables have a significant positive influence on capital formation only. The result that renewables do not have a significant impact on trade balance implies that renewables do not have an import substitution effect. Thus, we confirm the positive relationship between renewable energy and GDP through the path of increasing capital formation, but not for the path of increasing trade balance

    A dynamic macroeconomic model of the Wisconsin economy is used to estimate the economic impacts of displacing a portion of future investment in fossil fuel power plants (coal and natural gas) with renewable energy resources (biomass, wind, solar and hydro). The results show that renewable energy investments produce over three times more jobs, income and economic activity than the same amount of electricity generated from coal and natural gas power plants. Between 1995 and 2020, a 75% increase in renewable energy use generates approximately 65,000 more job-years of employment, $1.6 billion in higher disposable income and a $3.1 billion increase in gross regional product than conventional power plant investments. This includes the effects of a 0.3% average annual increase in electricity prices from renewable energy investments

    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)

    Full Text Available  Energy is the backbone of any development in any State. Renewable Energy (wind, solar and biomass appears currently as a major strategic energy source for a sustainable development particularly for developing or under developing societies. Use of renewable Energy will challenge major technological changes, by achieving energy production and saving. In particular by replacing fossil fuel, a significant cut of environmental impact and green house gas emission (GHG could be achieved. In addition Renewable Energy could offer a sustainable development for different societies particularly those in rural area (e.g. desert or isolated islands. The significant technical renewable energy tool developments in developed States could be much easier to be transferred to or copied in developing States .

    The unsustainability of conventional energy sources and its environmental destructions are well-known; the sustainability of renewable energy and its environmental benefits are also well-documented. The United States in common with many other countries is increasingly focused on developing renewable energy. At first, the pursuit of this strategy in U.S. was seen more as a way to reduce dependence on oil importation. With increased awareness of environmental challenges resulting from the consumption and production of conventional energy, an additional strategy for the continued interest in renewable energy development in the United States was as a result of its potential to ameliorate environmental problems. The U.S. government are utilizing policy measures and dedicating funding to encourage the development of renewable energy technologies. Beside government policies, there are contextual factors that also affect renewable energy production. These include, but not limited to population growth, energy demand, economic growth, and public acceptance. Given the pressing need to develop a sustainable energy, this study embarks on an outcome assessment of the nature of relationship of renewable energy policy incentives, and selected contextual factors on renewable energy production in the United States. The policy incentive evaluated in this study is the Renewable Energy Production Incentive program. The contextual factors evaluated in this study are energy consumption, population growth, employment, and poverty. Understanding the contextual factors within which policies are placed is essential to defining the most appropriate policy features. The methodological approach to the study is quantitative, using panel data from 1976 to 2007. The study tested two hypotheses using fixed effect estimation with robust standard error as a statistical model. Statistical analyses reveal several interesting results which lend support that besides policy incentives, contextual factors

    Present trends of electrical energy supply and demand are not sustainable because of the huge gap between demand and supply in foreseeable future in India. The path towards sustainability is exploitation of energy conservation and aggressive use of renewable energy systems. Potential of renewable energy technologies that can be effectively harnessed would depend on future technology developments and breakthrough in cost reduction. This requires adequate policy guidelines and interventions in the Indian power sector. Detailed MARKAL simulations, for power sector in India, show that full exploitation of energy conservation potential and an aggressive implementation of renewable energy technologies lead to sustainable development. Coal and other fossil fuel (gas and oil) allocations stagnated after the year 2015 and remain constant up to 2040. After the year 2040, the requirement for coal and gas goes down and carbon emissions decrease steeply. By the year 2045, 25% electrical energy can be supplied by renewable energy and the CO 2 emissions can be reduced by 72% as compared to the base case scenario. (author)

Several studies over this subject do exist and some companies have a considerable know-how in this field. One particularly important question is the impact of non-renewable energy taxes. An answer is available from already published studies: taxes with a yearly yield of 800 millions CHF (about 500 millions USD) would create a net number of 60,000 to 84,000 new jobs, provided that they are integrally used for renewable energy support [de

    2014-07-01

    This paper investigates empirically the effect of market regulation and renewable energy policies on innovation activity in different renewable energy technologies. For the EU countries and the years 1980 to 2007, we built a unique dataset containing information on patent production in eight different technologies, proxies of market regulation and technology-specific renewable energy policies. Our main findings show that lowering entry barriers is a more significant driver of renewable energy innovation than privatisation and un-bundling, but its effect varies across technologies, being stronger in technologies characterised by the potential entry of small, independent power producers. Additionally, the inducement effect of renewable energy policies is heterogeneous and more pronounced for wind, which is the only technology that is mature and has high technological potential. Finally, the ratification of the Kyoto protocol - determining a more stable and less uncertain policy framework - amplifies the inducement effect of both energy policy and market liberalisation.

    2013-01-01

    Feed-in tariffs have been the main policy instrument applied in Portugal for the promotion of electricity produced from renewable energy sources under the EU Directives on energy and climate regulation. In this paper, we provide an empirical impact assessment of the economic and environmental effects of Portugal's FITs policy to promote RES-E generation. Impact assessment of policy instruments plays a crucial role on decision-making process. For numerical simulations, we make use of a hybrid top-down/bottom-up general equilibrium modeling approach, which represents a reliable tool to analyze the complex interactions between economic, energy, and environmental issues related to energy policies. Numerical simulations confirm the empirical evidence that the FITs policy implemented by Portugal was both an effective and a cost-efficient way to increase the generation of electricity from renewable energy sources and thus to achieve the national RES-E target of 45% in 2010. Results show relatively modest macroeconomic impacts indicating potentially low economic adjustment costs. From an environmental perspective, the deployment of renewable energy source results in significant carbon emissions reductions. - Highlights: ► We provide an impact assessment of Portugal's FITs policy to promote RES-E generation. ► For numerical simulations, we make use of a hybrid top-down/bottom-up general equilibrium model. ► Portugal's FITs policy proved to be a cost-efficient way to increase generation of renewable electricity. ► Results show relatively modest macroeconomic effects indicating potentially low economic adjustment costs. ► The deployment of renewable energy sources results in significant carbon emission reductions

    Technologies using renewable energy sources are receiving increasing interest from both public authorities and power producing companies, mainly because of the environmental advantages they procure in comparison with conventional energy sources. These technologies can be substitution for conventional energy sources and limit damage to the environment. Furthermore, several of the renewable energy technologies satisfy an increasing political goal of self-sufficiency within energy production. The subject of this thesis is promotion of renewable technologies. The primary goal is to increase understanding on how technological development takes place, and establish a theoretical framework that can assist in the construction of policy strategies including instruments for promotion of renewable energy technologies. Technological development is analysed by through quantitative and qualitative methods. (BA)

    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.

  15. Of paradise and clean power: The effect of California's renewable portfolio standard on in-state renewable energy generation

    Science.gov (United States)

    Yin, Clifton Lee

    Renewable portfolio standards (RPS), policies that encourage acquisition of electricity from renewable energy sources, have become popular instruments for discouraging the use of climate change inducing-fossil fuels. There has been limited research, however, that empirically evaluates their effectiveness. Using data gathered by three governmental entities -- the federal-level Energy Information Administration and two California agencies, the Employment Development Department and the Department of Finance -- this paper investigates the impact of California's RPS, one of the nation's most ambitious such policies, on in-state renewable energy generation. It finds that the California RPS did not bring about a one-time increase in generation with its inception, nor did it compel an increase in generation over time. These results raise questions as to the best way to structure RPS policies in light of growing interest in the establishment of a national RPS.

    Renewable energy is one of the key technologies through which the energy needs of the future can be met in a sustainable and carbon-neutral manner. Increasing the share of renewable energy in the total energy mix of each country is therefore a critical need. While different countries have approached this in different ways, there are some common aspects which influence the pace and effectiveness of renewable energy incorporation. This presentation looks at data and information from 34 selected countries, analyses the patterns, compares the different parameters and identifies the common factors which positively influence renewable energy incorporation. The most successful countries are analysed for their renewable energy performance against their GDP, policy/regulatory initiatives in the field of renewables, landmass, climatic conditions and population to identify the most influencing factors to bring about positive change in renewable energy share.

    2016-03-01

    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

    The article examines the potential effectiveness of the renewable energy policy in China and its regulatory Law framework. It frames the option of renewable energy technology within the background of the long-lasting electricity problems that China has faced including serious supply shortages, reliance on coal, and severe environmental contamination. Its dual administrative and ownership system based on state and privately owned industry is discussed together with the market reform measures adopted in the sector. Current renewable energy policy is analysed, and the scope of the 2005 Renewable Energy Promotion Law is investigated. This is conducted within the context of the electricity sector reform that China adopted, and its effects upon the prospects of encouraging as well as expanding the development of renewable energy. This study draws upon primary information collected from interviews with stakeholders on the policy adequacy, and identifies three main types of shortcomings that have interfered with a more successful expansion of renewable energy in China.

    2006-01-01

    In this paper, three models have been projected namely Modified Econometric Mathematical (MEM) model, Mathematical Programming Energy-Economy-Environment (MPEEE) model, and Optimal Renewable Energy Mathematical (OREM) model. The actual demand for coal, oil and electricity is predicted using the MEM model based on economic, technological and environmental factors. The results were used in the MPEEE model, which determines the optimum allocation of commercial energy sources based on environmental limitations. The gap between the actual energy demand from the MEM model and optimal energy use from the MPEEE model, has to be met by the renewable energy sources. The study develops an OREM model that would facilitate effective utilization of renewable energy sources in India, based on cost, efficiency, social acceptance, reliability, potential and demand. The economic variations in solar energy systems and inclusion of environmental constraint are also analyzed with OREM model. The OREM model will help policy makers in the formulation and implementation of strategies concerning renewable energy sources in India for the next two decades

    This document proposes a synthesis of debates organised within the frame the two sessions of a conference on renewable energies. The first session addressed the place given to renewable energies in the French energy mix. Contributions proposed an overview of industrial ambitions for the different sectors: wind energy (bidding projects leading to a French specialisation in offshore wing energy), photovoltaic (issue of re-structuration and development, and of technology selection), sea energy (French position, European situation), hydraulic (renewal of the sector through a renewal of hydroelectric concessions), biomass (level of exploitation), and biogas-bio-diesel-bio-ethanol (issue of economic viability). A second set of contributions addressed the financing cost of sector development (results of an inquiry commission on electricity cost, question of the efficiency of mechanisms of financial support of renewable energies, CSPE and purchase tariff, energy cost for the consumer with a sustainable energy mix, education opportunities for future jobs). The second session addressed the relationship between renewable energies and economic growth. A first set of contribution addressed the technological orientations (super grids, European cooperation, investment programs for transport and connection to renewable energies, returns on experience on smart grids), and a second set addressed the synergies between innovation and territories (partnership between research centres and local communities or private sector, supporting small and medium enterprises in their innovation and export efforts, implementation of local energy policy tools such as PCET and SRCAE, integration of protection of the environment in urban equipment and furniture, progress in energy renovation and struggle against fuel poverty)

    Governments worldwide aim at reducing CO2 emissions and expanding renewable energy. A key element in achieving such a goal is to use renewable energy in transport such as biofuels. However, efforts to promote single transport technologies and single fuels only represent a partial solution...... transport. It is concluded that a 100 per cent renewable energy transport system is possible but is connected to significant challenges in the path towards it. Biomass is a limited resource and it is important to avoid effecting the production. The integration of the transport with the remaining energy....... No single technology can solve the problem of ever increasing CO2 emissions from transport. Transport must be integrated into energy planning, as electricity and heating. In this paper, a coherent effort to integrate transport into energy planning is proposed, using multiple means promoting sustainable...

  5. Promotion strategies for renewable energy in Taiwan

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

    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

    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.

    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

    The recent measures in the European Union promote the usage of renewable energies and enhancing the energy efficiency. These measures also effect agriculture, on the one hand by using biofuels mixed into fuel for machinery. Besides biofuels animal farms have opportunities in using renewable energy in several other ways. There are sectors in animal farming, where the energy demand is continuously high in electricity (e.g. forage grinders, mixers, milk coolers, air ventilation systems) or in heating (e.g. stables for poultry or piglets). Beside the energy demand in agricultural sector there are several products and side products suitable for energy production. For example different kinds of organic manures and corn silage could be raw materials for biogas production; plant residues like cereal straw and corn stalk bales could be combusted in boilers. Furthermore solar cells or solar collectors can be mounted on the big roof surfaces of animal farm buildings. Among animal farming sectors, dairy farming in the most energy intensive, and uses the widest variety of energy forms. It is often mentioned as the "heavy industry" of animal farming. In this research 14 dairy farms were examined in Hajdú-Bihar County in the topic of energy demand, renewable energy usage. The questioned farms covers 35% of the dairy cow population in Hajdú-Bihar County. The questions covered the general attributes of the farms and the details of the (existing or planned) renewable energy application. In terms of economic analysis saving, the investment return time and the employment effect was examined. The results show wide variety of applied renewable energy application. Fifty percent of farms uses at least one kind of renewable energy. Two biogas plants, 6 boilers for solid biomass, 2 solar cells. Regarding employment effect biogas plants created some full time workplaces, biomass boilers also needs some work hours to maintain, but none of the farms applied more labour. Besides renewable

    The EurObserv'ER policy profiles give a snapshot of the renewable energy policy in the EU Member States. With Ireland's current 'trajectory' of renewable energy growth, it is likely to slightly fall short of its 2020 nationally binding renewable energy target. Ireland initiated a 'moratorium' on its REFIT (Renewable Energy Feed-in Tariff) support scheme in December 2015, with the aim of introducing a revised scheme in 2017 in line with market developments. Grants and tax relief remain in place for renewable heat promotion. An Offshore Renewable Energy Development Plan (OREDP) was introduced in 2014, which sets out Government policy in relation to the sustainable development of Ireland's abundant offshore renewable energy resource

    2005-01-01

    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

    2008-09-29

    Renewable energy can play a fundamental role in tackling climate change, environmental degradation and energy security. As these challenges have become ever more pressing, governments and markets are seeking innovative solutions. Yet, what are the key factors that will determine the success of renewable energy policies? How can current policies be improved to encourage greater deployment of renewables? What impact can more effective policies have on renewables' share in the future global energy mix and how soon? This publication addresses these questions. Responding to the Gleneagles G8 call for a clean and secure energy future, it highlights key policy tools to fast-track renewables into the mainstream. This analysis illustrates good practices by applying the combined metrics of effectiveness and efficiency to renewable energy policies in the electricity, heating and transport sectors. It highlights significant barriers to accelerating renewables penetration, and argues that the great potential of renewables can be exploited much more rapidly and to a much larger extent if good practices are adopted. Carefully designed policy frameworks, customised to support technologies at differing stages of maturity, will deliver a strong portfolio of renewable energy technologies. The document provides recommendations on key principles for policy design as a template for decision makers.

    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....

    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

    Renewable energy is the effective solution for the harmonious coexistence of human and environment as well as for the sustainable development. Marine renewable energy as one of the renewable energies, potentially offer fewer environmental risks and thus community acceptance than other renewable energy developments. Government support is the key and initial power for developing marine renewable energy. To promote the development and utilization of marine renewable energy, the Chinese government has established the special funding plan for marine renewable energy, and released “the 13th Five-years Plan (2016-2020) for marine renewable energy”. This paper describes the mechanisms established by the marine renewable Energy policy in China, and provides a comparative analysis of the Chinese marine renewable energy policy framework. We provides some policy recommendations for future development of marine renewable energy in China.

    The United Nations Economic Commission for Europe (UNECE) covers a large and diverse region comprising 56 member states. These countries have different energy situations and vary in their potential for and progress in renewable energy and energy efficiency. The present report covers 17 UNECE countries, with the aim of establishing a data baseline and providing a general overview of their renewable energy situations. Over the past decade, the national governments of the selected countries have been working actively to leverage this renewable energy potential. Energy security and access to reliable, affordable, sustainable and modern energy are the key concerns driving renewable energy deployment. These countries require more substantial investment to fully realise its renewable potential and to bring innovative solutions to tackle their energy challenges, such as heating in urban and rural areas. A reliable data baseline is a pre-requisite and an enabler for more investment activity. The UNECE has contributed actively to fulfilling the 17 countries' aspirations in renewable energy by providing them with a platform for collaboration among UNECE member states. In 2014, a UNECE Group of Experts on Renewable Energy was established to step up these efforts. Its mandate is to carry out action-oriented, practical activities to significantly increase the uptake of renewable energy, in line with the United Nations Secretary-General's Sustainable Energy for All (SE4All) initiative. This UNECE Renewable Energy Status Report strives to present analysis of up-to-date data and information on the status of renewable energy and energy efficiency in the selected countries of the UNECE region

    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.

    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.

    2009-01-01

    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.)

    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.

    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.

    Full Text Available Environmental friendly renewable energy plays an indispensable role in energy industry development. Foreign direct investment (FDI in advanced renewable energy technology spillover is promising to improve technological capability and promote China’s energy industry performance growth. In this paper, the impacts of FDI renewable energy technology spillover on China’s energy industry performance are analyzed based on theoretical and empirical studies. Firstly, three hypotheses are proposed to illustrate the relationships between FDI renewable energy technology spillover and three energy industry performances including economic, environmental, and innovative performances. To verify the hypotheses, techniques including factor analysis and data envelopment analysis (DEA are employed to quantify the FDI renewable energy technology spillover and the energy industry performance of China, respectively. Furthermore, a panel data regression model is proposed to measure the impacts of FDI renewable energy technology spillover on China’s energy industry performance. Finally, energy industries of 30 different provinces in China based on the yearbook data from 2005 to 2011 are comparatively analyzed for evaluating the impacts through the empirical research. The results demonstrate that FDI renewable energy technology spillover has positive impacts on China’s energy industry performance. It can also be found that the technology spillover effects are more obvious in economic and technological developed regions. Finally, four suggestions are provided to enhance energy industry performance and promote renewable energy technology spillover in China.

    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

    2015-01-01

    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.

  7. The role of international sustainable development law principles in enabling effective renewable energy policy – a South African perspective.

    Directory of Open Access Journals (Sweden)

    Michelle Barnard

    2012-08-01

    Full Text Available It is universally accepted that renewable energy is an important contributing factor towards the promotion of sustainable development. The implementation of renewable energy needs to be regulated in an effective manner which in turn necessitates the formulation of law and policy geared towards sustainable development. Recent policy developments in South Africa propose to facilitate the promotion of sustainable development through the implementation of renewable energy, among others. In terms of existing energy policy in South-Africa, the interconnectivity of renewable energy and sustainable development is evident. Most notably, the White Paper on Renewable Energy of 2003 promotes increased access to affordable renewable energy in order to contribute to sustainable development. Moreover, the 2008 first review of the National Energy Efficiency Strategy of the Republic of South-Africa of 2005 states that in order for the country’s renewable energy policy to be considered sustainable, it needs to facilitate development in the social, economic and environmental spheres. Notwithstanding, attaining the goal of sustainable development depends on whether all its effecting principles are catered for in the policy developments. Accordingly, in order to ascertain whether South-African law and policy can successfully facilitate/enable sustainable development via the implementation of renewable energy, a specific methodology is proposed. In terms of the New Delhi Declaration of 2002 there are 7 principles of international law effecting sustainable development. These principles will be used as criteria in a principled assessment of South-African renewable energy law and policy in order to establish whether the goal of promoting sustainable development would be effected through the national policy developments.

    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.

    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.

    2016-01-01

    Russian renewable energy policy, introduced in May 2013, is a capacity mechanism-based approach to support wind, solar, and small hydro power development in Russia. This paper explores the effect of the new mechanism on the profitability of new renewable energy investments with a numerical example. The sensitivity of project profitability to selected factors is studied and the results are compared ceteris paribus to results from a generic feed-in premium case. Furthermore, the paper gives a complete and detailed presentation of the capacity price calculation procedure tied to the support mechanism. The results show that the new Russian renewable energy capacity mechanism offers a significant risk reduction to the investor in the form of dampening the sensitivity to external market factors. At the same time it shields the energy market system from excessive burden of renewable energy support. Even if the complexity of the method is a clear drawback to the detailed understanding of how the mechanism works, the design of the incentive policy could be an appealing alternative also for other emerging economies. - Highlights: •New Russian RE investment incentive mechanism is presented in detail. •Effect of the mechanism on RE investment profitability is numerically illustrated. •Sensitivity of project profitability to selected variables is studied. •Sensitivity results are compared to results under a generic feed-in premium. •The mechanism is shown to reduce market-related risks of RE investments.

    In this paper we investigate the choices citizens make when asked to express willingness to support a proposed energy policy and are then compelled to allocate the program funds to either renewable energy or energy efficiency. In a survey study based on a random sample of residents of the state of Maine, USA, we find that citizens have preferences for specific types of renewable energy but these preferences do not yield significantly different allocation of investment funds between renewable energy and energy efficiency. We find that preferences are generally consistent regardless of presentation of options (i.e. limited ordering effects). Our results also indicate that personal characteristics that are understudied in the energy literature, including promotion/prevention focus and social/fiscal leanings, influence both willingness to support energy policies and also their allocation of fund choices, but in different ways. This suggests the importance of including multiple options in energy policy proposals, and that targeted messages regarding the components of such policies is key for optimal communication. - Highlights: • Support for energy policies depends on the type of renewable energy included. • Citizens chose to allocate more funds to energy efficiency than renewable energies. • Promotion or prevention focus impacts support for policy and allocation decisions. • Social and fiscal leanings impact support and allocation, in different ways.

  19. The first step towards a 100% renewable energy-system for Ireland

    International Nuclear Information System (INIS)

    Connolly, D.; Leahy, M.; Lund, H.; Mathiesen, B.V.

    2011-01-01

    In 2007 Ireland supplied 96% of the total energy demand with fossil fuels (7% domestic and 89% imported) and 3% with renewable energy, even though there are enough renewable resources to supply all the energy required. As energy prices increase and the effects of global warming worsen, it is essential that Ireland begins to utilise its renewable resources more effectively. Therefore, this study presents the first step towards a 100% renewable energy-system for Ireland. The energy-system analysis tool used was EnergyPLAN, as it accounts for all sectors of the energy-system that need to be considered when integrating large penetrations of renewable energy: the electricity, heat, and transport sectors. Initially, a reference model of the existing Irish energy-system was constructed, and subsequently three different 100% renewable energy-systems were created with each focusing on a different resource: biomass, hydrogen, and electricity. These energy-systems were compared so that the benefits from each could be used to create an 'optimum' scenario called combination. Although the results illustrate a potential 100% renewable energy-system for Ireland, they have been obtained based on numerous assumptions. Therefore, these will need to be improved in the future before a serious roadmap can be defined for Ireland's renewable energy transition. (author)

    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

  2. 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

    In Pakistan, about two-thirds of the primary energy requirements are met through conventional sources while traditional biomass accounts the remaining one-third The primary commercial energy is largely based on fossil fuels. Indigenous reserves of oil and gas are limited and the coal available in the country is of poor quality. Environmental pollution and greenhouse gas emissions from energy use are becoming significant environmental issues in the country. Achieving solutions to these environmental problems requires long-term potential actions for sustainable development. In this regard, renewable energy resources appear to be one of the most efficient and effective solutions. Pakistan's geographical location has several advantages for extensive use of most of these renewable energy sources. This paper presents review of the present energy situation and environmental sustainability, and assesses the potential of renewable energy sources in Pakistan. Also, potential solutions to current environmental problems are identified along with renewable energy technologies. Several problems relating to renewable energy sources, environmentally sustainable development are discussed from both current and future perspectives. The present study shows that there is substantial potential of renewables in Pakistan. For achieving environmentally sustainable development, renewables must be developed and utilized. (author)

  6. Financing investments in renewable energy: the impacts of policy design

    The costs of electric power projects utilising renewable energy technologies (RETs) are highly sensitive to financing terms. Consequently, as the electricity industry is restructured and new renewables policies are created, it is important for policymakers to consider the impacts of renewables policy design on RET financing. This paper reviews the power plant financing process for renewable energy projects, estimates the impact of financing terms on levelised energy costs, and provides insights to policymakers on the important nexus between renewables policy design and financing. We review five case studies of renewable energy policies, and find that one of the key reasons that RET policies are not more effective is that project development and financing processes are frequently ignored or misunderstood when designing and implementing renewable energy policies. The case studies specifically show that policies that do no provide long-term stability or that have negative secondary impacts on investment decisions will increase financing costs, sometimes dramatically reducing the effectiveness of the program. Within U.S. electricity restructuring proceedings, new renewable energy policies are being created, and restructuring itself is changing the way RETs are financed. As these new policies are created and implemented, it is essential that policymakers acknowledge the financing difficulties faced by renewables developer and pay special attention to the impacts of renewables policy design on financing. As shown in this paper, a renewables policy that is carefully designed can reduce renewable energy costs dramatically by providing revenue certainty that will, in turn, reduce financing risk premiums.

    The International Energy Agency has identified the development of renewable energy sources as a key element to mitigate climate change. At the same time it has projected India to be the second-largest contributor to the increase in global energy demand to 2035. India hence faces a significant challenge to ensure its energy security by diversifying its power generation mix. In the wake of the creation of a Green Climate Fund in Cancun, this paper studies empirically the effect of the introduction of the Electricity Act 2003 and the Tariff Policy 2006, as well as the implementation of feed-in tariffs and minimum quotas on clean electricity sourcing, on the development of grid-connected renewable energy power in nine Indian States over the period 2001–2009. Results suggest that the passing of the Tariff Policy 2006, state-level policies, quantity-based instruments and a greater participation of the private sector have played a key role in promoting the development of installed capacity from renewable energy power in the nine States of the sample. - Highlights: ► First empirical analysis on renewable energy power development in India. ► National and state-level regulation analysis in nine Indian States. ► Use of panel data over the period 2001–2009. ► The Tariff Policy 2006, state-level policies and RPOs have played a key role.

    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 main objectives of this thesis are: to investigate technological change and cost reduction for a number of renewable electricity technologies by means of the experience curve approach; to address related methodological issues in the experience curve approach, and, based on these insights; and to analyze the implications for achieving the Dutch renewable electricity targets for the year 2020 within a European context. In order to meet these objectives, a number of research questions have been formulated: What are the most promising renewable electricity technologies for the Netherlands until 2020 under different technological, economic and environmental conditions?; To what extent is the current use of the experience curve approach to investigate renewable energy technology development sound, what are differences in the utilization of this approach and what are possible pitfalls?; How can the experience curve approach be used to describe the potential development of partially new energy technologies, such as offshore wind energy? Is it possible to describe biomass fuel supply chains with experience curves? What are the possibilities and limits of the experience curve approach when describing non-modular technologies such as large (biomass) energy plants?; What are the main learning mechanisms behind the cost reduction of the investigated technologies?; and How can differences in the technological progress of renewable electricity options influence the market diffusion of renewable electricity technologies, and what implications can varying technological development and policy have on the implementation of renewable electricity technologies in the Netherlands? The development of different renewable energy technologies is investigated by means of some case studies. The possible effects of varying technological development in combination with different policy backgrounds are illustrated for the Netherlands. The thesis focuses mainly on the development of investment

    In this study, energy utilization and its major environmental impacts are discussed from the standpoint of sustainable development, including anticipated patterns of future energy use and subsequent environmental issues in Turkey. Several aspects relating to energy utilization, renewable energy, energy efficiency, environment and sustainable development are examined from both current and future perspectives. Turkey is an energy importing country, more than half of the energy requirement has been supplied by imports. Domestic oil and lignite reserves are limited, and the lignites are characterised by high ash, sulfur and moisture content. Because of increasing energy consumption, environmental pollution is becoming a serious problem in the future for the country. In this regard, renewable energy resources appear to be one of the most efficient and effective solutions for sustainable energy development and environmental pollution prevention in Turkey. Turkey's geographical location has several advantages for extensive use of most of these renewable energy sources. Especially hydropower, biomass, geothermal, solar and wind energy should be considered and seriously supported by governments and private sectors.

    We investigate the effectiveness of policies in favor of innovation in renew- able energy under different levels of competition. Using information regarding renewable energy policies, product market regulation and high-quality green patents for OECD countries since the late 1970's, we develop a pre-sample mean count-data econometric specification that also accounts for the endogeneity of policies. We find that renewable energy policies are significantly more effective in fostering green innovation in countries with deregulated energy markets. We also find that public support for renewable energy is crucial only in the generation of high-quality green patents, whereas competition enhances the generation of green patents irrespective of their quality.

    This paper analyses the factors behind the deployment of renewable energy, focusing particularly on the effect of energy efficiency policies and measures. The impact of these factors is appraised within the context of several phases of the use of renewable sources. We therefore apply the quantile regression technique to a set of 21 European Countries in two time spans: from 1990 to 1998, and from 1999 to 2006. We control variables of policy, environment, socioeconomic characteristics, and electricity generation. For the second period, energy efficiency policies and measures concerning renewable sources effectively promote renewables, namely in the take-off phase. We shed light on the lobbying effect of traditional energy industries, showing that it depends both on the period under analysis, and on the kind of traditional energy source.

  3. Renewable energy islands in Europe

    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)

  4. Nuclear Energy and Renewables. System Effects in Low-carbon Electricity Systems - Executive Summary

    International Nuclear Information System (INIS)

    2012-01-01

    This report addresses the increasingly important interactions of variable renewables and dispatchable energy technologies, such as nuclear power, in terms of their effects on electricity systems. These effects add costs to the production of electricity, which are not usually transparent. The report recommends that decision-makers should take into account such system costs and internalise them according to a 'generator pays' principle, which is currently not the case. Analysing data from six OECD/NEA countries, the study finds that including the system costs of variable renewables at the level of the electricity grid increases the total costs of electricity supply by up to one-third, depending on technology, country and penetration levels. In addition, it concludes that, unless the current market subsidies for renewables are altered, dispatchable technologies will increasingly not be replaced as they reach their end of life and consequently security of supply will suffer. This implies that significant changes in management and cost allocation will be needed to generate the flexibility required for an economically viable coexistence of nuclear energy and renewables in increasingly de-carbonised electricity systems.

    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

    2012-01-01

    Highlights: ► We examined the renewable energy policies of the EU and Turkey in their historical perspectives. ► In the EU there is a progress in renewable energy planning and about support mechanisms. ► In Turkey there is a need for more struggles about increasing the effectiveness of support mechanism. ► The sustainability principle of the EU energy policy has to be a guide for Turkey. - Abstract: Renewable energy as one of the current and substantial issue needs to be investigated in terms of political outlook. So the researches on renewable energy policies under the energy policies of different countries are necessary. The emergence of renewable energy policy was the 20th century but it gained momentum in 21st century. The realization of the polluting nature of the petroleum products, their negative environment effects and the assumptions about the future of non-renewable energy sources were the driving forces behind these politics. The European Union in these conditions tries to play pioneer role. Turkey on the other hand as a candidate country has to harmonize its policies with the Union’s. In this context, objective of this work is to examine the EU and Turkey’s renewable energy policies, make a comparison and as a sustainability of Turkish renewable energy policy construct a future projection in short, medium and long terms.

    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.)

    Full Text Available The aim of this study is to systemize and present the quantitative and quality evaluation of the economic and non-economic effects of the implementation of the new mechanism of the support of renewable energy in Russia. It should allow meeting the middle-term goal of 2.5 % of renewables at the Russian wholesale electricity market by 2024. To achieve this aim, in the introduction part of the article, a detailed description of the new mechanism of the support of the renewable energy in Russia is presented. It is based on the payment for energy in the wholesale electricity market. The estimated aggregate positive effect resulting from this mechanism’s implementation was expected as follows: a replacement of non-renewable fossil fuels to renewable energy, b reduction of carbon dioxide emissions, c the average prices reduction in the wholesale electricity market, d reduction of the costs on environmental measures and health protection measures in traditional power generation, e creating new jobs, f reduction of fresh water used for cooling in traditional power generation, g multiplicative effects from the development of renewable energy and etc. The resulting economic effect is estimated at 47.77 billion rubles per year by 2024. The authors relied on expert estimates, forecasts of the Ministry of Energy and the Ministry of Economic Development, the Russian Energy Agency, the International Energy Agency, the International Agency for Renewable Energy, the Renewable Energy Policy Network for the 21st Century, the experience of foreign countries, the data of Russian Federal State Statistics Service.

  18. The myth and realities of renewable energy

    International Nuclear Information System (INIS)

    Shargal, M.; Houseman, D.

    2008-01-01

    Renewable energies use natural resources such as sunlight, wind, rain, tides, and geothermal heat, which are naturally replenished. Renewable energy technologies range from wind power, hydroelectricity, wave, solar, biomass, and biofuels. While most renewable energy sources do not produce pollution directly, the materials, industrial processes, and construction equipment used to create them may generate waste and pollution. This paper discussed the myths and realities of these energy applications. The following were described as being myths: plug-in cars could help reduce air pollution; current electric infrastructure can support the growth in plug-in cars; transmission grid can support the transportation of renewable electricity generated in rural areas to homes and business that need it in large metropolitan areas; there is a shortage of renewable energy sources on earth; biofuels do not have environmental issues; renewable energy facilities last forever; biofuel and biomass energy positively influence greenhouse gas; and greater efficiency results in lower energy consumption, resulting in energy independence. The paper also addressed the myth that ethanol is an eco-friendly fuel, and that if the United States tapped into its vast coal reserves effectively with clean and efficient coal-to-liquids technology, America would achieve energy independence. The paper also discussed the transformation from surplus fossil fuel resources to constrained gas and oil carriers, and subsequently to new energy supply and conversion technologies. Specifically, the paper addressed carbon offsets and allowance, cow power, and innovative experiments. It was concluded that the world is not on course to achieve a sustainable energy future. The global energy supply will continue to be dominated by fossil fuels for several decades. In order to reduce the resultant greenhouse gas emissions, a transition to zero and low-carbon technologies will be required. 10 refs

    The main objective of this special issue is to collect and disseminate publications that highlight recent advances and breakthroughs in the area of renewable energy resources. The use of these resources for production of electricity is increasing rapidly worldwide. As of 2015, a majority of countries have set renewable electricity targets in the 10%-40% range to be achieved by 2020-2030, with a few notable exceptions aiming for 100% generation by renewables. We are experiencing a truly unprecedented transition away from fossil fuels, driven by environmental, energy security, and socio-economic factors.Electric machines can be found in a wide range of renewable energy applications, such as wind turbines, hydropower and hydrokinetic systems, flywheel energy storage devices, and low-power energy harvesting systems. Hence, the design of reliable, efficient, cost-effective, and controllable electric machines is crucial in enabling even higher penetrations of renewable energy systems in the smart grid of the future. In addition, power electronic converter design and control is critical, as they provide essential controllability, flexibility, grid interface, and integration functions.

    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

    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

  10. Renewable, ethical? Assessing the energy justice potential of renewable electricity

    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.

    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.)

    2005-01-15

    Beginning with an overview of renewable energy sources including biomass, hydroelectricity, geothermal, tidal, wind and solar power, this book explores the fundamentals of different renewable energy systems. The main focus is on technologies with high development potential such as solar thermal systems, photovoltaics and wind power. This text not only describes technological aspects, but also deals consciously with problems of the energy industry. In this way, the topics are treated in a holistic manner, bringing together maths, engineering, climate studies and economics, and enabling readers to gain a broad understanding of renewable energy technologies and their potential. The book also contains a free CD-ROM resource, which includes a variety of specialist simulation software and detailed figures from the book. (Author)

    By the end of the 21 century, according to United National projections, the number of people on the earth is likely to have approximately doubled. How can a world of 10 to 12 billion people be provided with adequate supplies of energy, cleanly, safely and substantially? There is a growing consensus that renewable energy sources will be a very important part of the answer. The growing interest in 'renewables' has been prompted in part, by increasing concern over the pollution, resource depletion and possible climate change implications of our continuing use of conventional fossil and nuclear fuels. But recent technological developments have also improved the cost-effectiveness of many of the renewables, making their economic prospects look increasingly attractive. It describes the achievements and progress made in hydropower, biomass conversion, geothermal, solar thermal technology, wind energy conversion and the increasing usage of photovoltaics. It is evident that global warming is setting in and is going to change the climate as well as the terrain of many countries unless drastic measures are taken. The Kyoto meeting emphasised the importance of limiting CO 2 emissions and to abide by some form of agreement to reduce emissions. Present study concludes that renewable energy penetration into the energy market is much faster than was expected in recent years and by 2030, 15-20 percent of our prime energy will be met by renewable energy.

    2010-01-01

    China, one of the global biggest emitter of CO 2 , needs promotion renewable energy to reduce air pollution from its surging fossil fuel use, and to increase its energy supply security. Renewable energy in its infancy needs policy support and market cultivation. Wind power installed capacity has boomed in recent year in China, as a series of effective support policies were adopted. In this paper, I review the main renewable energy policies regarding to China's wind power, including the Wind Power Concession Program, Renewable Energy Law, and a couple of additional laws and regulations. Such policies have effectively reduced the cost of wind power installed capacity, stimulated the localization of wind power manufacture, and driven the company investment in wind power. China is success in wind power installed capacity, however, success in wind-generated electricity has yet achieved, mainly due to the backward grid system and lack of quota system. The paper ends with the recommended best practice of the China's wind power installed capacity might be transferable to China's photovoltaic power generation. (author)

    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.

    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)

    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 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.

  7. Energy minimization strategies and renewable energy utilization for desalination: a review.

    2011-02-01

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

    The 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.

  11. Renewable energies and their effect on electricity prices: the case of the German nuclear phase-out

    Energy Technology Data Exchange (ETDEWEB)

    Comtesse, Daniel; Schroeer, Sebastian

    2010-07-01

    The aim of this article is to analyze the price effects of the market integration of renewable energies. Previous related studies describe a so-called 'merit order-effect', implying that decreasing electricity prices are caused by an increasing share of renewable energies. However, this is a static effect resulting from the assumption that the existing power plant fleet remains constant. Our contribution is to analyze the long-run price effect of the substitution of renewable energies for existing technologies like nuclear power, coal or gas. This aspect is relevant, since more and more countries increase the share of renewable energies in order to substitute fossil or nuclear power plants. Higher market shares of renewable energies are caused both by their increasing competitiveness and by political actions such as national targets or promotion schemes. Background and Stylized facts Since renewable energies usually have a lower marginal price of electricity generation - which determines the electricity prices at spot markets - their addition to an established power plant fleet consisting of nuclear, coal, lignite and gas power plants leads to lower electricity prices. However, the long-run price effect when fossil or nuclear power plants are substituted remains ambiguous. This is due to the fact that, if compared to fossil and nuclear fuels, renewable energies are characterized by three specific features: firstly, they lack the ability to secure base load. Secondly, they produce energy which is extremely volatile. Thirdly, their marginal costs of production are close to zero. These characteristics are caused by the high dependency of renewable energies on weather conditions. As electricity generation and consumption must happen simultaneously (electricity storage does not pay off yet), power plants with low base load capacity need back-up capacities. Given the actual technological state of the art, these back-up capacities must be fossil or nuclear power

    Community is a much used word that is readily attached to projects, initiatives and policies as part of the discursive politics of modern governance. In this viewpoint, we consider the way in which community has become attached to renewable energy projects in the UK, both in grassroot action and in mainstream energy policy. We ask what those involved have seen as distinctive about community renewable energy projects that makes them different from other renewable energy installations. We identify a diversity of understandings and interpretations that revolve around questions of both process (who the project is by) and outcome (who the project is for). We evaluate the implications of this diversity, identifying the importance of the process of project development for realising the catalytic and learning effects of meaningful and substantial local involvement

    The Student Outreach with Renewable Energy Technology (SORET) program is a joint grant that involves a collaboration between three HBCU's (Central State University, Savannah State University, and Wilberforce University) and NASA John H. Glenn Research Center at Lewis Field. The overall goal of the grant is to increase the interest of minority students in the technical disciplines, to encourage participating minority students to continue their undergraduate study in these disciplines, and to promote graduate school to these students. As a part of SORET, Central State University has developed an undergraduate research associates program over the past two years. As part of this program, students are required to take special laboratory courses offered at Wilberforce University that involve the application of renewable energy systems. The course requires the students to design, construct, and install a renewable energy project. In addition to the applied renewable energy course, Central State University provided four undergraduate research associates the opportunity to participate in summer internships at Texas Southern University (Renewable Energy Environmental Protection Program) and the Cleveland African-American Museum (Renewable Energy Summer Camp for High School Students) an activity co sponsored by NASA and the Cleveland African-American Museum. Savannah State University held a high school summer program with a theme of the Direct Impact of Science on Our Every Day Lives. The purpose of the institute was to whet the interest of students in science, mathematics, engineering, and technology (SMET) by demonstrating the effectiveness of science to address real world problems. The 2001 institute involved the design and installation of a PV water pumping system at the Center for Advanced Water Technology and Energy Systems at Savannah State. Both high school students and undergraduates contributed to this project. Wilberforce University has used NASA support to provide

    In this report, different long-term evolutions of the Belgian future energy system are drafted, analysed and evaluated. All evolutions are designed to meet the requirement of a 100% renewable based national energy system by 2050. For this purpose, a baseline is developed which depicts an energy system without the stringent renewables' requirement. Next, different trajectories are sketched that lead up to a 100% renewable coverage in 2050. The trajectories show that it is feasible to combine economic growth and comfort with far going deployment of renewable energy sources, provided a number of key options and effective policies and measures are being implemented. These options were deducted from several discussions with stakeholders via an open dialogue process, as well as with national experts, and finally, were presented to the Steering committee. The analysis leads to the undeniable observation that drastic changes in a multitude of areas throughout society are required to obtain the desired level of renewable energy penetration in 2050, but also that such a transition can be realised through various sectoral, technology and inter-temporal choices. In other words, this study describes a vast number of different trajectories leading to a 100% renewable energy system in Belgium in the long term, as well as their socio-economic impacts.

    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)

  1. Innovation, renewable energy, and state investment: Case studies of leading clean energy funds

    Energy Technology Data Exchange (ETDEWEB)

    Wiser, Ryan; Bolinger, Mark; Milford, Lewis; Porter, Kevin; Clark, Roger

    2002-09-01

    Over the last several years, many U.S. states have established clean energy funds to help support the growth of renewable energy markets. Most often funded by system-benefits charges (SBC), the 15 states that have established such funds are slated to collect nearly $3.5 billion from 1998 to 2012 for renewable energy investments. These clean energy funds are expected to have a sizable impact on the energy future of the states in which the funds are being collected and used. For many of the organizations tapped to administer these funds, however, this is a relatively new role that presents the challenge of using public funds in the most effective and innovative fashion possible. Fortunately, each state is not alone in its efforts; many other U.S. states and a number of countries are undertaking similar efforts. Early lessons are beginning to be learned by clean energy funds about how to effectively target public funds towards creating and building renewable energy markets. A number of innovative programs have already been developed that show significant leadership by U.S. states in supporting renewable energy. It is important that clean energy fund administrators learn from this emerging experience.

In Hungary, electricity from renewable energy sources is supported by a feed-in-tariff or a market ('green') premium, depending on the capacity and energy source. Household-sized power plants up to 50 kVA can benefit from net metering. In general, subsidy programmes also promote the use of renewable energy sources in the electricity and heating sector. The main support scheme for the use of renewable energy in the transportation sector is a quota system supplemented by a reimbursement of excise duty

    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

    In most European countries, the renewable energies encounter success and gain ground. Denmark, Germany and Spain are in the pole position of this race. However, the situation in UK is different, surprising and paradoxical as revealed by the analysis made in this paper: implementation of an ambitious energy policy based on renewable obligations (RO) and renewables obligation certificates (ROCS) and on the massive development of wind energy, fuel cells and wave power but a lack of clarity, stability and efficiency in the programs of development of these energy sources.

    2006-01-01

    Increasing the proportion of power derived from renewable energy sources is becoming an increasingly important part of many countries' strategies to achieve reductions in greenhouse gas emissions. However, renewable energy investments can often have external costs and benefits, which need to be taken into account if socially optimal investments are to be made. This paper attempts to estimate the magnitude of these external costs and benefits for the case of renewable technologies in Scotland, a country which has set particularly ambitious targets for expanding renewable energy. The external effects we consider are those on landscape quality, wildlife and air quality. We also consider the welfare implications of different investment strategies for employment and electricity prices. The methodology used to do this is the choice experiment technique. Renewable technologies considered include hydro, on-shore and off-shore wind power and biomass. Welfare changes for different combinations of impacts associated with different investment strategies are estimated. We also test for differences in preferences towards these impacts between urban and rural communities, and between high- and low-income households. (author)

    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

  15. Dynamic life cycle assessment (LCA) of renewable energy technologies

    Energy Technology Data Exchange (ETDEWEB)

    2006-01-01

    Before new technologies enter the market, their environmental superiority over competing options must be asserted based on a life cycle approach. However, when applying the prevailing status-quo Life Cycle Assessment (LCA) approach to future renewable energy systems, one does not distinguish between impacts which are 'imported' into the system due to the 'background system' (e.g. due to supply of materials or final energy for the production of the energy system), and what is the improvement potential of these technologies compared to competitors (e.g. due to process and system innovations or diffusion effects). This paper investigates a dynamic approach towards the LCA of renewable energy technologies and proves that for all renewable energy chains, the inputs of finite energy resources and emissions of greenhouse gases are extremely low compared with the conventional system. With regard to the other environmental impacts the findings do not reveal any clear verdict for or against renewable energies. Future development will enable a further reduction of environmental impacts of renewable energy systems. Different factors are responsible for this development, such as progress with respect to technical parameters of energy converters, in particular, improved efficiency; emissions characteristics; increased lifetime, etc.; advances with regard to the production process of energy converters and fuels; and advances with regard to 'external' services originating from conventional energy and transport systems, for instance, improved electricity or process heat supply for system production and ecologically optimized transport systems for fuel transportation. The application of renewable energy sources might modify not only the background system, but also further downstream aspects, such as consumer behavior. This effect is, however, strongly context and technology dependent. (author)

  17. Translating EU renewable energy policy for insular energy systems: Reunion Island's quest for energy autonomy

    Directory of Open Access Journals (Sweden)

    Matthew Sawatzky

    2017-12-01

    Full Text Available Recognition of the negative impacts of climate change has led to agreement on the need to decarbonise energy systems through the employment of renewable energy. With many national and transnational policies in place, the options available to insular energy systems (IES differ from those of interconnected areas due to fragility in their production and distribution networks. Based on the concepts of policy mobility and translation, this study examines the interplay of EU renewable energy policy and insular governance processes aimed at achieving energy autonomy through renewable energy development. Reunion Island, a French Overseas Department and Region, is used as a case study to examine local energy governance processes, aspects that shape regional translation of national and EU policy, and the potential effects that create structures and pathways of energy transition. The study shows that Reunion Island’s regional Energy Governance Committee has significant application potential as a governance tool in other IES and small islands within the EU, but that renewable energy development is restricted due to national policy measures and path dependent governance structural constraints.

  18. Renewable energy policy and landscape management in Andalusia, Spain: The facts

    Prados, Maria-Jose

    2010-01-01

    Renewable energy has developed spectacularly in Spain since the European Union started a process of energy policy reform. A review of Spanish State legislation on renewable energies confirms that the success in installing renewable energy is attributable to public aid. Andalusia is one of the autonomous communities, which has simultaneously developed the legal framework and very successfully implemented the introduction of renewable power. When implementing the central government's policy, the Andalusian regional government prioritised increases in both surface cover by wind and solar plants (thermal and photovoltaic energy) and in the number of companies involved. However, this development of renewable energies took place without any proper integration into regional spatial and landscape planning. This paper explores renewable power implementation in Andalusia through regulatory measures put in place over the last decade to develop renewable energy systems and the way they can be managed alongside planning issues. The location of large-scale renewable plants has had consequences for territory in the socio-political context of renewable energy promotion. The main findings focus on renewable energy plant sprawl throughout rural areas in Andalusia with no clear effect on landscape management and no firm backing from the local population.

  19. Renewable energies in the EU

    International Nuclear Information System (INIS)

    Heller, W.

    2008-01-01

    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.)

    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.

    Decoupling the environmental attributes of renewable energy (RE) generation from the physical unit of energy is an innovative mechanism for marketing green or renewable power. The introduction of 'Tradable Renewable Energy Credits' (TRECs) allows the green power attributes of energy to be sold or traded separately from the physical unit of energy. Since the green power certificate system removes potential locational and physical bottlenecks, both suppliers and consumers gain flexibility in the marketplace. The TREC is also an efficient tool to meet 'Renewable Portfolio Standard' (RPS) required by different states in the US. This paper discusses the RPS requirements for different states and examines the implications of an integrated TREC market. It offers a competitive setting to the consumers to pay for renewable energy and a cost effective tool to support renewable energy generation [Grace and Wiser, 2002]. This paper also highlights some practical difficulties that should be addressed in order to establish an efficient integrated TREC market

  3. The Park of Renewable Energy geoethical project

    Full Text Available The Park of Renewable Energy is an environmental technology park in the middle of Italy that has an innovative integrated system for the production of renewable energy. Recently, the Park launched a public invitation: to become part of a great widespread community for the production of renewable energy, and to promote energy conservation and a sustainable lifestyle. This empowerment process that turns consumers into energy producers – and also into those who convey the culture of sustainability – might, over time, give life to a community that actually lives according to the geoethical principles of biosustainability. The route for the identification and dissemination of the Park of Renewable Energy community is an interesting example of the generative process, whereby rather than doggedly pursuing a predetermined objective, such as a model to be implemented, the actors involved, “look for directions and values that are inherent in the means available” [Bateson 2000], including communication networks and methodologies of social participation. The community components focus their attention on the action and relationship effects, rather than on ways to reach a predefined goal. In this perspective, the Park of Renewable Energy experience aims to become an interesting object of observation and reflection for its green ethics. This ecological approach promises unexpected new creations: there is a chance we will at last see the birth of a sustainable form of social organization adapted to the human community.

    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.

    2010-01-01

    Despite the increasing amount of literature available on renewable energy, the empirical analysis about drivers promoting renewables remains scarce. We have analyzed those drivers for European Countries. Over an extended period of time (1990-2006) we used panel data techniques, namely the fixed effects vector decomposition. The results suggest that both the lobby of the traditional energy sources (oil, coal, and natural gas) and CO 2 emissions restrain renewable deployment. The objective of reducing energy dependency appears to stimulate renewable energy use. Our results robustly support the EU decision to create a directive promoting the use of renewable sources (Directive 2001/77/EC). We also offer suggestions with regards to the design of appropriate policies towards renewable energy deployment.

    International Nuclear Information System (INIS)

    Anon.

    2010-01-01

    Public policy and funding are basically different, but both are needed to develop the renewable energy market. Public policy creates incentives, but also obligations. The setting up of a 'repurchase rate' also called a 'feed-in tariff' or 'clean energy cash back scheme' obliges electric power companies to buy back energy of renewable origin at a fixed, guaranteed rate. The extra-cost generated, although usually low, is passed on to all customers and does not cost the State anything. Funding is characterized by its source, the manner in which it is obtained and who supplies it, whether it be banks, mutual funds, development agencies, electric power companies, local governments or the consumers themselves. Repurchasing yields regular cash flows over a given period at a lower risk and allows banks to provide funding. This is one of the reasons for its success. This solution is also very popular with political leaders because it does not weigh down public funding. Both these reasons explain why repurchasing is so appreciated in Europe and in a growing number of countries, more than seventy having adopted it in 2010. In addition, it is regularly discounted in relation to technological breakthroughs and lower costs. As is the case in Europe, the problem lies in maintaining an acceptable rate while avoiding excessive project profitability. In Europe, for instance, the number of renewable energy projects is such that consumers are starting to complain about seeing their electricity rates rise because of the famous feed-in tariff, even though the cost of renewable energies continues to drop on a regular basis. The United States and a few other countries, including China, prefer the quota system, or RPS (Renewable Portfolio Standards), which requires electric power companies to generate a minimal share of electric power by a renewable energy source. These companies consequently invest in renewable energy projects or purchase this energy from other suppliers. Like the

    The use of renewable energy is tightly connected to solving social problems in Estonia by creating more new jobs. It is essential that Estonia should increase the use of biofuels. One of the biofuels, firewood, has been used already for centuries. For wider use of renewable energy in Estonia, it is not enough to rely only on enterprices. Rather, before any serious progress can take place, the state should create the appropriate legal environment. Due to its many social and environmental aspects, renewable energy is more important to the state than a sole enterprice. Unfortunately, Estonian government has been delaying its duties. Estonia has two resources that should be taken advantage of, fertile spare land and people still used to the country life. The country people would get work by growing different energy crops on the spare land. (author)

The main incentive for renewable energy use in transport are tax exemptions and subsidies

  1. Financing renewable energy: Obstacles and solutions

    Energy Technology Data Exchange (ETDEWEB)

    Brown, M.H.

    1994-06-01

    The majority of renewable energy technology projects now being developed use long term project financing to raise capital. The financial community scrutinizes renewables more closely than some conventionally fueled electric generation facilities because it perceives renewables as risky and expensive. Renewables pay for this perceived risk through higher interest charges and other more restrictive loan covenants. Risks that are not eliminated in the power sales agreement or through some other means generally result in higher project costs during financing. In part, this situation is a product of the private placement market and project finance process in which renewable energy facilities must function. The project finance process attracts banks and institutional lenders as well as equity investors (often pension funds) who do not want to place their capital at great risk. Energy project finance exists on the basis of a secure revenue stream and a thorough understanding of electric generation technology. Renewables, like all energy projects, operating in uncertain regulatory environments are often difficult to finance. In the uncertain regulatory environment in which renewables now operate, investors and lenders are nervous about challenges to existing contracts between independent power producers and utilities. Challenges to existing contracts could foretell challenges to contracts in the future. Investors and lenders now look to state regulatory environments as an indicator of project risk. Renewable energy technology evolves quickly. Yet, often the information about technological evolution is not available to those who invest in the energy projects. Or, those who have invested in new renewable energy technology in the past have lost money and are nervous about doing so in the future - even though technology may have improved. Inadequate or unfavorable information is a barrier to the development of renewables.

    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

    The European renewable energy industry has the potential to be a world leader. This has been achieved within the European region for specific technologies, through a set of policy activities at a national and regional level, driven primarily by employment, energy self-sufficiency and industrial competitiveness. Using the experience gained in recent years, European industry has the opportunity to continue to expand its horizons on a worldwide level. Through the use of the SAFIRE rational energy model, an assessment has been made of the future penetration of renewable energy within Europe and the effects on these socio-economic factors. In conjunction with these outputs, assessments of the worldwide markets for wind, photovoltaics, solar thermal plant and biomass have been assessed. A case study of the Danish wind industry is used as a prime example of a success story from which the learning opportunities are replicated to other industries, so that the European renewable energy industry can achieve its potential.

    About 3 quarter of the Italian electric power comes from fossil fuel power plants. The rest is generated from hydropower, few comes from biomass and wind energy and a very few from geothermal energy (2% of the national production). However, the situation is changing and geothermal energy, with only 5 TWh, makes Italy the European leader in this domain and the world number 4 behind USA, Philippines and Mexico. The renewable sources represent 18.5% of the total Italian energy production. During the last five years, the renewable energy sources have developed rapidly: +80% per year for the wind energy, +32% per year for biomass and about +3% per year for geothermal energy. Moreover, the Italian government is implementing incentives for the development of renewable energy sources. This article gives an overview of the situation. (J.S.)

    1998-04-01

    The recent formation of the Quebec Association for the Production of Renewable Energy (l`Association quebecoise de la production d`energie renouvelable - AQPER) was announced. The Association is becoming the centre of the Quebec private electricity generation industry. By communicating the industry`s message to the public the organization gives much needed visibility to renewable resources, new forms of energy and sustainable development. The new group is an outgrowth of the former Quebec Association of Private Hydroelectricity Producers. In its new reincarnation, the organization represents all forms of renewables, small and medium hydro, wind, solar, forest and agricultural biomass and urban waste. With deregulation of the electricity market, specifically the creation of the Regie de l`energie` in Quebec, the wider role is a welcome boost for renewable energy development in the province. In one of its first actions the AQPER recommended that all hydroelectric sites up to 50 MW be reserved for development exclusively by the private sector, in conformity with the Quebec energy policy announced in 1996.

    It has been shown that international cooperation in achieving renewable energy targets, e.g., via a common tradable green certificate market, increases overall welfare. However, cooperation in the support of electricity from renewable energy sources also leads to regional price effects, from which some groups benefit while others lose. On a regional level, the introduction of cross-border cooperation in RES-E support generally has an opposite effect on support expenditures and wholesale electricity prices, as long as grid congestion between the different regions exists. In this paper, a theoretical model is used to analyze under which conditions different groups bene t or suffer from the introduction of cooperation. Findings of the analysis include that effects on consumers and total producers per country can only be clearly determined if no grid congestions between the countries exist. If bottlenecks in the transmission system exist, the relationship between the slopes of the renewable and the non-renewable marginal generation cost curves for electricity generation as well as the level of the RES-E target essentially determine whether these groups bene t or lose from the introduction of green certificate trading. In contrast, system-wide welfare always increases once cooperation in RES-E support is introduced. Similarly, welfare on the country level always increases (compared to a situation without RES-E cooperation) if the countries are perfectly or not at all physically interconnected. In the case of congested interconnectors, each country always at least potentially benefits from the introduction of certificate trade, taking into account possible distributions of congestion rents between the countries.

    Creation of an internal market for renewable electricity will involve a political negotiation process, similar to previous European Union (EU) greenhouse gas negotiations. The Energy Ministers in the EU have agreed upon an overall target of 22% of electricity supply from Renewable Energy Sources (RES-E) and a distribution of targets over the individual Member States. The REBUS project provides insights in the effects of implementing targets for renewable electricity generation at EU Member State level and the impact of introducing burden sharing systems within the EU, such as a Tradable Green Certificate (TGC) system. Member States can participate in such burden sharing systems to reduce the costs of achieving RES-E targets. The project concentrated on the development of the REBUS model, which quantifies the impact of trade (in green certificates, quotas or targets), the specification of cost potential curves for renewable electricity options in each of the 15 EU Member States and the implementation of different rules to setting targets at individual Member State level. In addition, utilities and consumer organisations were interviewed on their requirements and expectations for an international burden sharing scheme. 49 refs

  4. Using net energy output as the base to develop renewable energy

    2010-01-01

    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.

    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

    2007-01-01

    This article analyzes the effects of renewable energy on the technical efficiency of 45 economies during the 2001-2002 period through data envelopment analysis (DEA). In our DEA model, labor, capital stock, and energy consumption are the three inputs and real GDP is the single output. Increasing the use of renewable energy improves an economy's technical efficiency. Conversely, increasing the input of traditional energy decreases technical efficiency. Compared to non-OECD economies, OECD economies have higher technical efficiency and a higher share of geothermal, solar, tide, and wind fuels in renewable energy. However, non-OECD economies have a higher share of renewable energy in their total energy supply than OECD economies

    1999-08-01

    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

    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'.

  18. Three Essays on Renewable Energy Policy and its Effects on Fossil Fuel Generation in Electricity Markets

    Science.gov (United States)

    Bowen, Eric

    In this dissertation, I investigate the effectiveness of renewable policies and consider their impact on electricity markets. The common thread of this research is to understand how renewable policy incentivizes renewable generation and how the increasing share of generation from renewables affects generation from fossil fuels. This type of research is crucial for understanding whether policies to promote renewables are meeting their stated goals and what the unintended effects might be. To this end, I use econometric methods to examine how electricity markets are responding to an influx of renewable energy. My dissertation is composed of three interrelated essays. In Chapter 1, I employ recent scholarship in spatial econometrics to assess the spatial dependence of Renewable Portfolio Standards (RPS), a prominent state-based renewable incentive. In Chapter 2, I explore the impact of the rapid rise in renewable generation on short-run generation from fossil fuels. And in Chapter 3, I assess the impact of renewable penetration on coal plant retirement decisions.

    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

    Generation trading between renewable energy and thermal power is an efficient market means for transforming supply structure of electric power into sustainable development pattern. But the trading is hampered by the output fluctuations of renewable energy and the cost differences between renewable energy and thermal power at present. In this paper, the external environmental cost (EEC) is defined and the EEC is introduced into the generation cost. At same time, the incentive functions of renewable energy and low-emission thermal power are designed, which are decreasing functions of EEC. On these bases, for the market risks caused by the random variability of EEC, the decision-making model of generation trading between renewable energy and thermal power is constructed according to the risk theory. The feasibility and effectiveness of the proposed model are verified by simulation results.

  1. The market for tradable renewable energy credits

    International Nuclear Information System (INIS)

    Berry, David

    2002-01-01

    As states seek to foster the development of renewable energy resources, some have introduced renewable portfolio standards (RPSs) which require retailers of electricity to derive a specified amount of their energy supply from renewable energy resources. RPSs in Texas, Arizona, Wisconsin and Nevada allow for or require the use of tradable renewable energy credits. The price of such credits is expected to reflect the cost premium for generating electricity from renewable resources relative to the market price of conventionally generated electricity. Using the market to trade renewable energy credits exposes buyers and sellers to risks of imperfect information, poor performance, and opportunism. These risks can be managed through contractual arrangements and regulatory requirements pertaining to property rights in credits, pricing, term of the contract, and assurance of performance

    The generally acknowledged sources of renewable energy are wind, geothermal, biomass, solar, hydropower, and hydrogen. Renewable energy technologies are crucial to the production and utilization of energy from these regenerative and virtually inexhaustible sources. Furthermore, renewable energy technologies provide benefits beyond the establishment of sustainable energy resources. For example, these technologies produce negligible amounts of greenhouse gases and other pollutants in providing energy, and they exploit domestically available energy sources, thereby reducing our dependence on both the importation of fossil fuels and the use of nuclear fuels. The market price of renewable energy technologies does not reflect the economic value of these added benefits.

    The global attention has always been focused on the adverse environmental impacts of conventional energy sources. In contrast nonconventional energy sources, particularly the renewable ones, have enjoyed a clean image vis a vis environmental impacts. The only major exception to this general trend has been large hydropower projects; experience has taught that they can be disastrous for the environment. The belief now is that mini hydro and microhydro projects are harmless alternatives. But are renewable energy sources really as benign as is widely believed? The present essay addresses this question in the background of Lovin's classical paradigm which had postulated the hard (malignant) and soft (benign) energy concepts in the first place. It then critically evaluates the environmental impacts of major renewable energy sources. It then comes up with the broad conclusion that renewable energy sources are not the panacea they are popularly perceived to be; indeed in some cases their adverse environmental impacts can be as strongly negative as the impacts of conventional energy sources. The paper also dwells on the steps needed to utilize renewable energy sources without facing environmental backlashes of the type experienced from hydropower projects

    2010-07-01

    Marine renewable energy sources can provide Nova Scotia with a large supply of sustainable, non-carbon emitting electricity. One of the largest tidal ranges within the world is contained within the Bay of Fundy, which holds power potential in the form of wind, wave and tidal energy. A strategic environmental assessment (SEA) on the Bay of Fundy's potential marine renewable energy was published in 2008. An assessment of the social, economic, and environmental effects and factors linked with possible development of renewable energy sources in the Bay Fundy was published. Twenty-nine recommendations were offered, including the creation of marine renewable energy legislation incorporating sustainability principles. This discussion paper described the policy drivers and opportunities in Nova Scotia for marine renewable energy sources as well as the challenges and relevant subject areas that should be considered when creating marine renewable energy legislation and policy. Specific challenges that were discussed included a policy approach to development; multiple jurisdictions; Aboriginal issues; economic factors; environmental impacts; occupational and operation safety; allocation of rights; and regulatory issues. It was concluded that if the marine renewable energy resource was going to be created with the possibility of providing commercial electricity generation, a coordinated legislative framework should be established. refs., tabs.

    Renewable energy policy focuses on supporting the deployment of renewable power generators so as to reduce their costs through scale economies and technological learning. It is expected that, once cost parity with fossil fuel generation is achieved, a transition towards renewable power should continue without the need for further renewable energy subsidies. However, this reasoning implicitly assumes that the cost of fossil fuel power generation does not respond to the large scale penetration of renewable power. In this paper we build a standard economic framework to test the validity of this assumption, particularly in the case of coal and gas fired power generation. We find that it is likely that the cost of fossil fuel power generation will respond to the large scale penetration of renewables, thus making the renewable energy transition slower or more costly than anticipated. More analysis is needed in order to be able to quantify this effect, the occurrence of which should be considered in the renewable energy discourse. - Highlights: • Renewables are increasingly competing with fossil fuel power generation. • This may have various effects on the fossil fuel generation value chain. • One such possible effect is a response of fossil fuel prices to renewables deployment. • We have tested this hypothesis using a supply-demand analytical framework. • We found that the effect is likely to occur and should be further investigated.

    Latvia is among those countries that do not have gas, coal and, for the time being, also oil resources of its own. The amount of power produced in Latvia does not meet the demand, consequently a part of the power has to be purchased from neighbouring countries. Firewood, peat and hydro resources are the only significant domestic energy resources. Massive decrease of energy consumption has been observed since Latvia regained independence. Domestic and renewable energy resources have been examined and estimated. There are already 13 modern boiler houses operating in Latvia with total installed capacity 45 MW that are fired with wood chips. Latvian companies are involved in the production of equipment. 7 small HPPs have been renewed with the installed capacity 1.85 MW. Wind plant in Ainazi has started its operation, where two modern wind turbines with the capacity of 0.6 MW each have been installed. Mechanism of tariff setting is aligned.

    Greenhouse crop evolution if from one hand improves the quality of products and productive cycles, from another hand cause negative effects on the natural resources, the environment and the economy of the country. Although renewable energies already feature to some extent in the European Union's regional, the 2007-2013 Structural Funds package could be the occasion to increase the weight given to RES within the energy programmes for less favoured regions (particularly in ex-objective 1 areas). In those areas, greenhouse crop sector is particularly developed as agriculture industrial activity. According to numerous investigations, agricultural greenhouse consumption for greenhouse acclimatization represents approximately between 2% to 6% of the E U's-27 total energy consumption. This report is intended to give a general overview to the potential of renewable energy and technology in Italy, particularly geothermal, wind and solar (thermic and photovoltaic) as energy for greenhouse crop sector. RES have a high potential for developing of indigenous resources, service activities, new job creation and reducing Co2 emissions. [it

  17. Economic impacts from the promotion of renewable energy technologies. The German experience

    International Nuclear Information System (INIS)

    Frondel, Manuel; Ritter, Nolan; Schmidt, Christoph M.; Vance, Colin

    2010-01-01

    The allure of an environmentally benign, abundant, and cost-effective energy source has led an increasing number of industrialized countries to back public financing of renewable energies. Germany's experience with renewable energy promotion is often cited as a model to be replicated elsewhere, being based on a combination of far-reaching energy and environmental laws that stretch back nearly two decades. This paper critically reviews the centerpiece of this effort, the Renewable Energy Sources Act (EEG), focusing on its costs and the associated implications for job creation and climate protection. We argue that German renewable energy policy, and in particular the adopted feed-in tariff scheme, has failed to harness the market incentives needed to ensure a viable and cost-effective introduction of renewable energies into the country's energy portfolio. To the contrary, the government's support mechanisms have in many respects subverted these incentives, resulting in massive expenditures that show little long-term promise for stimulating the economy, protecting the environment, or increasing energy security.

    2008-07-01

    Renewable energy can play a fundamental role in tackling climate change, environmental degradation and energy security. As these challenges have become ever more pressing, governments and markets are seeking innovative solutions. Yet, what are the key factors that will determine the success of renewable energy policies? How can current policies be improved to encourage greater deployment of renewables? What impact can more effective policies have on renewables’ share in the future global energy mix and how soon? Deploying Renewables: Principles for Effective Policies addresses these questions. Responding to the Gleneagles G8 call for a clean and secure energy future, it highlights key policy tools to fast-track renewables into the mainstream. This analysis illustrates good practices by applying the combined metrics of effectiveness and efficiency to renewable energy policies in the electricity, heating and transport sectors. It highlights significant barriers to accelerating renewables penetration, and argues that the great potential of renewables can be exploited much more rapidly and to a much larger extent if good practices are adopted. Carefully designed policy frameworks, customised to support technologies at differing stages of maturity, will deliver a strong portfolio of renewable energy technologies. Deploying Renewables: Principles for Effective Policies provides recommendations on key principles for policy design as a template for decision makers.

  19. Renewable Energy and Proven Oil Reserves Relation: Evidence from OPEC Members

    Full Text Available The well documented literature on the relation between energy consumption and climate change has been extended by the addition of renewable energy consumption. Several studies show its impact on technical efficiency, per capita income or carbon dioxide (CO2 emission levels for developed and developing countries. However, to the extent of our knowledge, very few of them state the importance of renewable energy for the countries where the main type of fossil fuels, oil, is exported. This study aims to explore the association between renewable energy, real gross domestic product (GDP, CO2 emission level, real oil prices as well as the proven oil reserves for seven members of Organization of the Petroleum Exporting Countries (OPEC. The analyses are conducted using panel data techniques, namely fixed effect – random effect tests. Our results show a positive and significant relation between renewable energy consumption, and real GDP and CO2 emission level. A statistically not significant coefficient is found for the relation between renewable energy and the proven oil reserves. The relation between energy and real oil prices is also insignificant.

    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).

    The Directive 2009/28/EC on the promotion of the use of energy from renewable sources (RES) sets the overall target to reach 20% renewable energy in gross final energy consumption in 2020. This target is broken down into binding individual Member State targets. Reaching these targets will require a huge mobilization of investments in renewable energies in the coming decade. In order to improve financing and coordination with a view to the achievement of the 20 % target, Article 23 (7) of the Directive requires the Commission to present an analysis and action plan with a view to: (a) The better use of structural funds and framework programmes; (b) The better and increased use of funds from the European Investment Bank and other public finance institutions; (c) Better access to risk capital; (d) The better coordination of Community and national funding and other forms of support; (e) The better coordination in support of renewable energy initiatives whose success depends on action by actors in several Member States. This report presents the results of the title project. The study provides an up to date and thorough assessment of the costs of renewable energy and the support and financing instruments available for renewable energy R and D, demonstration projects and large-scale deployment. This includes details of each Member State's expenditure (via grants, support schemes, loans etc.) and use of Community funds, including loans of the EIB (European Investment Bank) and the EBRD (European Bank for Reconstruction and Development). It also explores the possible instruments for use in the future and constraints in the capital market, which hinder the development of renewable energy. Finally, it develops recommendations for improving financing and support instruments, improving the sector's access to capital, and closing the financing gap for reaching the 2020 targets. The chapters of the report represent separate tasks: (1) Costs of renewable energy

    Use of renewable energy sources is one solution to decrease green house gas emissions and the use of polluting fossil fuels. Renewables differ in their environmental and societal impacts, and to design sound renewable energy policy, societies need to assess the trade-offs between alternative sources. To enable the evaluation and comparison of renewable energy production alternatives in Finland, this paper applies the choice experiment to elicit the monetary information on people's preferences for four renewable energy sources: wind power, hydro power and energy from crops and wood, and considers four impacts of energy production: effects on biodiversity, local jobs, carbon emissions and household's electricity bill. The nested logit analysis reveals that higher income, male gender, young age, and pro-environmental attitude increase the probability to choose renewable energy instead of the current energy mix. Wind power is, on average, the most popular renewable energy technology, but regional differences exist. Biodiversity deterioration should be avoided. The national aggregate willingness to pay, based on stated preferences rather than preferences revealed by actual market behavior, for a combination of renewable energy technologies that corresponds to Finland's climate change and energy policy is over 500 million Euros. - Highlights: • Preferences for renewable energy sources are elicited with choice experiment. • Wind power is the most popular source in general. • Regional differences exist: energy from wood is favored in rural areas. • Biodiversity deterioration should be avoided

    The aim of this project was to monitor performance of PV systems on the Renewable Energy Centre and the Eco-Energy House at the School of Built Environment, University of Nottingham. The Renewable Energy Centre was constructed using a cash donation from Beacon Energy Limited, while construction of the Eco-Energy House was funded by David Wilson Homes Ltd. The primary role of these facilities is to assist in renewable energy technology transfer. Both buildings were designed to be thermally efficient and utilize a range of renewable energy systems. They will be used to attract and educate visitors from local government, schools and collages, and the general public. This report documents the design process for Building Integrated Photovoltaic (BIPV) systems on the two buildings. The buildings are significantly different in both construction and occupancy but are sited close to each other and share similar weather conditions. The rationale behind the BIPV designs is explained and detail is provided on the final solutions for each building. A number of methods were used to assist in the selection of appropriate PV systems to integrate into each building. These included energy analysis using PVSYST3 software, CAD modelling for aesthetics assessment, architectural and construction considerations and economic justification. The design chosen for Renewable Energy Centre was a vertical wall PV facade system using thin film technology, while a roof integrated system using monocrystalline PV roofing slates was chosen for the Eco-Energy House. In terms of economic justification, both systems cannot be said to be cost effective at the current market price for energy, however, the aim was to bring the technology to the attention of a wide audience and demonstrate the potential of the systems for reducing CO{sub 2} emission to the environment.

    The southwestern part of the US has abundant supply of renewable energy resources but little is known about the consumers' preferences for renewable energy in this region. This paper investigates households' willingness to pay for a renewable energy program in a southwestern state, New Mexico (NM). Using the contingent valuation method, we provide different scenarios that include provision of 10% and 20% of renewable energy supply, to elicit households' willingness to pay (WTP) for the renewable energy. We estimate the WTP for specific shares of renewable energy in the total energy mix as it is a key factor in affecting the price of the energy portfolio in the market. The survey design also allows us to check the scope sensitivity of renewable energy which can help guide the future renewable energy policy. We hope results from this study will offer useful insights to energy regulators and utility companies and help them increase the share of renewable energy supply. - Highlights: ► We estimate willingness to pay (WTP) for renewable energy in the southwestern US. ► Households' WTP in New Mexico is estimated using the contingent valuation method. ► WTP is estimated for 10% - 20% shares of renewable energy in the total energy mix. ► WTP estimates indicate scope sensitivity for a larger share of renewable energy.

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

    St Denis, Genevieve; Parker, Paul

    2009-01-01

    An emerging trend in Canada is the creation of community energy plans, where decisions that used to be left to regional level energy agencies or private individuals are now being considered at the community level. A desire to reduce greenhouse gas emissions and to become more energy self-sufficient is driving this change. Theoretically, local level management is desirable because it achieves these goals through improvements in the three areas of energy efficiency, energy conservation and switching to renewable energy sources. The analysis of 10 of the first community energy plans in Canadian communities, ranging in population size from 500 to one million, finds that communities are choosing policies and programs centred on increasing energy efficiency and conservation while renewable energy receives much less attention. Municipal operations were called upon to set higher targets than the general community. Communities that recognized the substantial potential of renewable energy often focused on technologies that the municipal sector could implement, such as bio-fuels for their transportation fleet. Wind, passive solar design, solar photovoltaics and solar thermal options were only recommended in a few cases. Overall, only one of the five larger communities (Calgary) recommended implementing multiple renewable energy technologies while three of the five smaller communities proposed multiple renewable energy sources. The implication is that smaller and more remote communities may be the most willing to lead in the planned introduction of renewable energy systems. (author)

    Highlights: ► Feedback of decisions to the market: large companies can have an impact on prices in the market. ► Multiple uncertainties: analysis of uncertainties emanating from both markets and environment. ► Policy analysis: impact of uncertainty about the durability of feed-in tariffs. -- Abstract: The liberalization of electricity markets in recent years has enhanced competition among power-generating firms facing uncertain decisions of competitors and thus uncertain prices. At the same time, promoting renewable energy has been a key ingredient in energy policy seeking to de-carbonize the energy mix. Public incentives for companies to invest in renewable technologies range from feed-in tariffs, to investment subsidies, tax credits, portfolio requirements and certificate systems. We use a real options model in discrete time with lumpy multiple investments to analyze the decisions of an electricity producer to invest into new power generating capacity, to select the type of technology and to optimize its operation under price uncertainty and with market effects. We account for both the specific characteristics of renewables and the market effects of investment decisions. The prices are determined endogenously by the supply of electricity in the market and by exogenous electricity price uncertainty. The framework is used to analyze energy policy, as well as the reaction of producers to uncertainty in the political and regulatory framework. In this way, we are able to compare different policies to foster investment into renewables and analyze their impacts on the market.

    This report presents an overview of the state of conventional energy sources and the potential for development of renewable energy sources in the Central Asia countries of Kazakhstan, Uzbekistan, Kyrgyzstan, Turkmenistan, and Tajikistan. The region has a population of about 50 million in an area of more than four million square kilometers. The per capita gross internal product is more than $2,500, although the economy has been declining the past five years. The area has substantial coal, oil, uranium, and natural gas reserves, although they are not distributed equally among the five countries. Energy production is such that the countries do not have to rely heavily on imports. One of the problems in Central Asia is that the energy prices are substantially below the world prices. This is a factor in development of renewable energy sources. The primary renewable energy resources available are wind in Kazakhstan, solar in the entire region, biomass in Kyrgyzstan, and micro-hydropower stations in Kazakhstan and Kyrgyzstan. All of these have the potential to provide a significant amount of the required energy for the region. However, all of the countries have an abundance of various renewable energy resources. To effectively use these resources, however, a number of barriers to their development and commercialization must be overcome. These include low prices of conventional energy sources, absence of legislative support, lack of financing for new technologies, and lack of awareness of renewable energy sources by the population. A number of specific actions are proposed to overcome these barriers. These include establishment of a Central Asia coordinating council for renewable energy, development of a regional renewable energy program, and setting up a number of large demonstration projects. 16 figs.

  18. The share of renewable energy in the EU. Country Profiles. Overview of Renewable Energy Sources in the Enlarged European Union

    International Nuclear Information System (INIS)

    2004-01-01

    The promotion of renewable energy has an important role to play in addressing the growing dependence on energy imports in Europe and in tackling climate change. Since 1997, the Union has been working towards the ambitious target of a 12% share of renewable energy in gross inland consumption by 2010. In 1997, the share of renewable energy was 5.4%; by 2001 it had reached 6%. This Staff Working Document gives an overview of the different situations of renewable energy sources in the European Union. It includes part of the formal report that the Commission is required to make under Article 3 of Directive 2001/77/EC on electricity from renewable energy sources, and it completes the overall picture with information at a country level on the heat produced from renewable energies and biofuels in the transport sector. This Staff Working Document complements the Communication on 'The share of Renewable Energy sources in the EU'. Data is based on different sources. Firstly, on the reports from Member States on national progress in achieving the targets on electricity from renewable energy sources. Secondly, on a study launched by the Commission on the evolution of renewable energy sources. And thirdly, on a variety of sources like the European Barometer of renewable energies, data from the industry, etc. With the enlargement of the European Union, the new Member States are required to adopt the RES-E Directive (renewable energy sources for electricity) by 1 May 2004. In the accession treaty, national indicative targets are set and the overall renewable electricity target for the enlarged Union will therefore be 21% of gross electricity consumption by 2010. The Commission has the legal obligation to report on the degree of achievement of new Member States' targets by 2006. Although it is too early to assess RES-policy in the new Member States due to very recently adopted regulations, this document also includes national information on the States now joining the European Union

    2007-01-01

    Photovoltaics and renewable energies are growing at a much faster pace than the rest of the economy in Europe and worldwide. This and the dramatic oil price increases in 2005 have led to a remarkable re-evaluation of the renewable energy sector by politics and financing institutions. Despite the fact that there are still discrepancies between the European Union and the USA, as to how to deal with climate change, renewable energies will play an important role for the implementation of the Kyoto Protocol and the worldwide introduction of tradable Green Certificates. Apart from the electricity sector, renewable energy sources for the generation of heat and the use of environment friendly biofuels for the transport sector will become more and more important in the future.

    1991-01-01

    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

    The world has to face increasing energy needs while it is today dependent of fossil fuels at 80%. Getting out of the fossil fuels dependence model requires an important effort to promote the energy saving and the carbon-free energies as well, and in particular the renewable energy sources. Taking all this information into account, the authors evaluate the global share that renewable energies could represent in the energy mix, in France and in the entire world. This share represents today only 10% of the energy consumed, but will it remain marginal or will it become important and eventually prominent? (J.S.)

    Concerns arising due to the variability and intermittency of renewable energy sources while integrating with the power grid can be mitigated to an extent by incorporating a storage element within the renewable energy harnessing system. Thus, battery energy storage systems (BESS) are likely to have a significant impact in the small-scale integration of renewable energy sources into commercial building and residential dwelling. These storage technologies not only enable improvements in consumption levels from renewable energy sources but also provide a range of technical and monetary benefits. This paper provides a modelling framework to be able to quantify the associated benefits of renewable resource integration followed by an overview of various small-scale energy storage technologies. A simple, practical and comprehensive assessment of battery energy storage technologies for small-scale renewable applications based on their technical merit and economic feasibility is presented. Software such as Simulink and HOMER provides the platforms for technical and economic assessments of the battery technologies respectively. (author)

    The analysis of different global energy scenarios in part I of the report confirms that the exploitation of energy efficiency potentials and the use of renewable energies play a key role in reaching global CO2 reduction targets. An assessment on the basis of a broad literature research in part II shows that the technical potentials of renewable energy technologies are a multiple of today's global final energy consumption. The analysis of cost estimates for renewable electricity generation technologies and even long term cost projections across the key studies in part III demonstrates that assumptions are in reasonable agreement. In part IV it is shown that by implementing technical potentials for energy efficiency improvements in demand and supply sectors by 2050 can be limited to 48% of primary energy supply in IEA's ''Energy Technology Perspectives'' baseline scenario. It was found that a large potential for cost-effective measures exists, equivalent to around 55-60% of energy savings of all included efficiency measures (part V). The results of the analysis on behavioural changes in part VI show that behavioural dimensions are not sufficiently included in energy scenarios. Accordingly major research challenges are revealed.

    2012-01-01

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

It is also a revolution in China's energy production and consumption and a promotion of energy. This article focuses on the status of the development of new energy and renewable energy in China. After analyzing the problems in China's development and understanding the related policies, we look forward to the prospects of China's future and renewable energy sources.

  12. 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

    2014-08-01

    After having recalled the European objectives for 2020 related to climate change and sustainable energies (reduction of greenhouse gas emissions, share of renewable energies, and increase of energy efficiency), data are presented under the form of tables and graphs and discussed. These data concern the share of the different energy sources (coal, oil and oil products, gas, non renewable electricity, renewable energies, non renewable wastes) in the energy consumption for each of the 28 European countries, the evolutions of energy consumption and GDP between 2005 and 2012, the share of renewable energies in each European country, the level of greenhouse gas emissions in 2012 in each country and the target level for 2020, the evolution of greenhouse gas emissions and of GDP between 2005 and 2012. It appears that oil remains the main source in European energy consumption, that the share of renewable energies is nearly twice as it was in 2005, that three member states have already reached their objective in terms of share of renewable energies, and that fifteen countries have already reached their objectives of greenhouse gas emissions

    2008-01-01

    The use of renewable energy has a long history. Biomass, for instance, has been used for heating and cooking, while wind has been used in the irrigation of fields and to drive windmills for centuries. Although Turkey has many energy resources, all of these with the exception of coal and hydropower, cannot meet the total energy demand. Turkey has been importing resources to meet this deficit. These resources have become increasingly expensive and also have undesirably high emissions ratings. Turkey has an extensive shoreline and mountains and is rich in renewable energy potential. The share of renewables on total electricity generation is 29.63% while that of natural gas is 45% for the year 2006. The projection prepared for the period between 2006 and 2020 aims an annual growth of 8% for the total electricity generation. According to this projection, it is expected that renewables will have a share about 23.68% with a decrease of 5.95% while natural gas will have a share about 33.38% for 2020. This paper presents the present state of world renewable energy sources and then looks in detail at the potential resources available in Turkey. Energy politics are also considered. (author)

Iran also is not an exception of this progress. Renewable energy is energy that is provided by renewable sources such as the sun or wind. In general renewable energies are not adaptable to every single community. Because of location and special climate conditions of Iran most applicable renewable energy systems in Iran are solar and wind energy. Main purpose of this paper is to review and identify most applicable renewable energy systems of Iran and also review on traditional and current methods that utilized to obtain maximum use of these renewable energies.

  3. Clean energy funds: An overview of state support for renewable energy

    Energy Technology Data Exchange (ETDEWEB)

    Bolinger, Mark; Wiser, Ryan

    2001-04-01

    Across the United States, as competition in the supply and delivery of electricity has been introduced, states have sought to ensure the continuation of ''public benefits'' programs traditionally administered or funded by electric utilities. Many states have built into their restructuring plans methods of supporting renewable energy sources. One of the most popular policy mechanisms for ensuring such continued support has been the system-benefits charge (SBC), a non-bypassable charge to electricity customers (usually applied on a cents/kWh basis) used to collect funds for public purpose programs. Thus far, at least fourteen states have established SBC funds targeted in part towards renewable energy. This paper discusses the status and performance of these state renewable or ''clean'' energy funds supported by system-benefits charges. As illustrated later, existing state renewable energy funds are expected to collect roughly $3.5 billion through 2012 for renewable energy. Clearly, these funds have the potential to provide significant support for clean energy technologies over at least the next decade. Because the level of funding for renewable energy available under these programs is unprecedented and because fund administrators are developing innovative and new programs to fund renewable projects, a certain number of program failures are unavoidable. Also evident is that states are taking very different approaches to the distribution of these funds and that many lessons are being learned as programs are designed, implemented, and evaluated. Our purpose in this paper is therefore to relay early experience with these funds and provide preliminary lessons learned from that experience. It is our hope that this analysis will facilitate learning across states and help state fund managers develop more effective and more coordinated programs. Central to this paper are case studies that provide information on the SBC-funded renewable

    We use panel cointegration techniques to examine the relationship between renewable energy consumption, trade and output in a sample of 11 African countries covering the period 1980–2008. The results from panel error correction model reveal that there is evidence of a bidirectional causality between output and exports and between output and imports in both the short and long-run. However, in the short-run, there is no evidence of causality between output and renewable energy consumption and between trade (exports or imports) and renewable energy consumption. Also, in the long-run, there is no causality running from output or trade to renewable energy. In the long-run, our estimations show that renewable energy consumption and trade have a statistically significant and positive impact on output. Our energy policy recommendations are that national authorities should design appropriate fiscal incentives to encourage the use of renewable energies, create more regional economic integration for renewable energy technologies, and encourage trade openness because of its positive impact on technology transfer and on output. - Highlights: • We examine the relationship between renewable energy consumption, trade and output in African countries. • There is a bidirectional causality between output and trade in both the short and long-run. • In the short-run, there is no causality between renewable energy consumption and trade or output. • In the long-run, renewable energy consumption and trade have a statistically significant positive impact on output. • African authorities should encourage trade openness because of its positive impact on technology transfer and on output

    This report describes the negative impacts from renewable energy sources on the Swedish environmental objectives. The result is presented as a set of conceptual cause-effect diagrams showing the links between the life-cycles of the energy sources to specific environmental objectives. The energy sources covered in the report are hydro power, wind power, thin-film solar cells, silicon-based solar cells, heat pumps, biofuels from crops (such as ethanol and rape seed methyl ester), biofuels from waste (i.e. biogas) and biofuels from the forest (such as wood pellets and chips). No environmental impacts have been quantified in this report, and no comparisons between the energy sources have been performed. However, what has been shown is that the above mentioned energy sources may influence many of the Swedish environmental goals, and that this influence will increase if the current Swedish goals for renewable energies are realized. More detailed studies of the renewable energy sources influences on the environmental goals are thus required in order to avoid negative environmental impacts from future developments of renewable energy sources. This report has, based on current scientific knowledge, tried to point out the most important possible influences from renewable energy technologies, and is therefore a starting point for further studies. The report also gives some recommendations for further research

    IRENA Renewable Energy Country Profiles take stock of the latest developments in the field of renewables at country level around the world. Each profile combines analysis by IRENA's specialists with the latest available country data and additional information from a wide array of sources. The resulting reports provide a brief yet comprehensive picture of the situation with regard to renewable energy, including energy supply, electrical generation and grid capacity, and access. Energy policies, targets and projects are also considered, along with each country's investment climate and endowment with renewable energy resources. The energy statistics presented here span the period from 2009 until 2012, reflecting varying timelines in the source material. Since data availability differs from country to country, wider regional comparisons are possible only for the latest year with figures available for every country included. Despite the time lag in some cases, the evident differences and disparities between countries and regions around the world remain striking. The current package of country profiles is just a starting point. The geographic scope will continue to expand, and existing profiles will be enhanced with new indicators, with the whole series maintained as a live product on the IRENA website (www.irena.org)

Subsurface energy storage systems such as salt caverns or porous formations offer the possibility of hosting large amounts of energy or substance. When employing these systems, an adequate system and process understanding is required in order to assess the feasibility of the individual storage option at the respective site and to predict the complex and interacting effects induced. This understanding is the basis for assessing the potential as well as the risks connected with a sustainable usage of these storage options, especially when considering possible mutual influences. For achieving this aim, in this work synthetic scenarios for the use of the geological underground as an energy storage system are developed and parameterized. The scenarios are designed to represent typical conditions in North Germany. The types of subsurface use investigated here include gas storage and heat storage in porous formations. The scenarios are numerically simulated and interpreted with regard to risk analysis and effect forecasting. For this, the numerical simulators Eclipse and OpenGeoSys are used. The latter is enhanced to include the required coupled hydraulic, thermal, geomechanical and geochemical processes. Using the simulated and interpreted scenarios, the induced effects are quantified individually and monitoring concepts for observing these effects are derived. This presentation will detail the general investigation concept used and analyze the parameter availability for this type of model applications. Then the process implementation and numerical methods required and applied for simulating the induced effects of subsurface storage are detailed and explained. Application examples show the developed methods and quantify induced effects and storage sizes for the typical settings parameterized. This work is part of the ANGUS+ project, funded by the German Ministry

    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. In general, these benefits are not financially valued in energy market pricing. In addition, energy sources that impact significantly on the environment are not financially

    The passing of the Renewable Energy Law (REL) in 2005 demonstrated China's commitment to renewable energy development. In the 3 years after the REL, China's renewable electricity capacity grew rapidly. From 2006 to 2008, China's wind capacity installation more than doubled every year for 3 years in a row. However, three facts prevent us from being optimistic about China's renewable electricity future. First, considered as a share of total capacity, renewable electricity capacity is decreasing instead of increasing. This is due simply to the rapid growth of fossil fuel capacity. Second, a significant amount of renewable generation capacity is wasted because it is not connected to the electricity grid. Finally, renewable electricity plants are running at a low level of efficiency. Based on an in-depth analysis of China's existing renewable energy policy, we suggest that these challenges should be dealt with by introducing a market-based mandatory renewable portfolio requirement coupled with strong regulatory monitoring of grid enterprises.

    The viability of many Renewable Energy projects is critically dependent upon the ability of these projects to secure the necessary financing on acceptable terms. The principal objective of the study was to provide an overview to project developers of project financing techniques and the conditions under which project finance for Renewable Energy schemes could be raised, focussing on the potential sources of finance, the typical project financing structures that could be utilised for Renewable Energy schemes and the risk/return and security requirements of lenders, investors and other potential sources of financing. A second objective is to describe the appropriate strategy and tactics for developers to adopt in approaching the financing markets for such projects. (author)

    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.

    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)

    2016-05-20

    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.

    Leduc, Sylvain; Patrizio, Piera; Yowargana, Ping; Kraxner, Florian

    2016-04-01

    Indonesia has experienced a constant increase of the use of petroleum and coal in the power sector, while the share of renewable sources has remained stable at 6% of the total energy production during the last decade. As its domestic energy demand undeniably continues to grow, Indonesia is committed to increase the production of renewable energy. Mainly to decrease its dependency on fossil fuel-based resources, and to decrease the anthropogenic emissions, the government of Indonesia has established a 23 percent target for renewable energy by 2025, along with a 100 percent electrification target by 2020 (the current rate is 80.4 percent). In that respect, Indonesia has abundant resources to meet these targets, but there is - inter alia - a lack of proper integrated planning, regulatory support, investment, distribution in remote areas of the Archipelago, and missing data to back the planning. To support the government of Indonesia in its sustainable energy system planning, a geographic explicit energy modeling approach is applied. This approach is based on the energy systems optimization model BeWhere, which identifies the optimal location of energy conversion sites based on the minimization of the costs of the supply chain. The model will incorporate the existing fossil fuel-based infrastructures, and evaluate the optimal costs, potentials and locations for the development of renewable energy technologies (i.e., wind, solar, hydro, biomass and geothermal based technologies), as well as the development of biomass co-firing in existing coal plants. With the help of the model, an optimally adapted renewable energy mix - vis-à-vis the competing fossil fuel based resources and applicable policies in order to promote the development of those renewable energy technologies - will be identified. The development of the optimal renewable energy technologies is carried out with special focus on nature protection and cultural heritage areas, where feedstock (e.g., biomass

    2009-01-01

    Decentralized wind, hydropower, biogas and biomass, geothermal, solar thermal and solar electricity energy systems are the most commonly found renewable energy technologies promoted for rural energy supply within sustainable developments programs. They are, therefore, seen to have a central place in the practice of sustainable development and in allowing less development countries to bypass the environmentally damaging fossil fuel intensive paths made by industrialized countries. On the political front, many less development countries are critical of pressure on them to adopt environmental energy technologies. Turkey is situated the meeting point of three continents (Asia, Europe and Africa) and stands as a bridge between Asia and Europe. The country is located in southeastern Europe and southwestern Asia. As Turkey's economy has expanded in recent years, the consumption of primary energy has increased. Presently in order to increase the energy production from domestic energy resources, decrease the use of fossil fuels as well as reduce of green house gas emissions different renewable energy sources are used for energy production in Turkey. The share of energy production from renewable energy sources has increased during the last 10 years. Turkey must import most of the energy to meet her needs. Turkey also has a large potential for renewable energies. The lack of knowledge about renewable energy technologies by most policy-makers, potential consumers, and energy firm managers has played against renewable energy developments. The paper presents renewable energy used in Turkey and Europe Union and evaluation of the market conditions and barriers of renewable energy use in Turkey. (author)

  10. Renewable Energies: How Far Can We Go?

    International Nuclear Information System (INIS)

    Philibert, C.

    2011-01-01

    A little over five years ago, in January 2006, Futuribles devoted a sizeable special number to energy prospects and the greenhouse effect (no. 315). These were already troubling times and the gloomy prospects for the development of energy resources and the problematic of climate change were analysed in a number of articles. According to certain experts, 'peak oil' was already reached in that same year of 2006: that is to say, oil production was thought to be at its height and would subsequently be stagnating before a (more or less rapid) decline. Furthermore, gas production ought to reach a ceiling around 2025-2030, as Jean Laherrere showed in these columns last April (no. 373). In this context and given the undeniable efforts to be made to limit global warming, it has become essential, on the one hand, to act to control energy use and, on the other, to look to other sources of energy production - this second option being doubtless easier to implement than reducing consumption. Incontestably, renewable energies have an essential future role to play in the diversification of the energy mix and its orientation towards sustainable development. Cedric Philibert, a specialist in these forms of power within the International Energy Agency, here outlines their potential and the place they might occupy in years to come. After presenting the IEA's scenarios to 2035 and 2050 (which reveal the need for proactive policies to promote renewable energies), he focuses on the two major strands in this sector: wind power and solar energy. He then goes on to the question of what is meant by 'renewable': are these energies 100% renewable or have the supplies to be supplemented, the resources to be stored etc.? He analyses the role renewable energies could play in buildings and in the various sectors of industry and transport and under what technical conditions this might occur. Lastly, Philibert examines the economic aspects: what costs for what benefits? He shows, in substance, that

    Increased economic growth and demand for energy in emerging economies is creating an opportunity for these countries to increase their usage of renewable energy. This paper presents and estimates two empirical models of renewable energy consumption and income for a panel of emerging economies. Panel cointegration estimates show that increases in real per capita income have a positive and statistically significant impact on per capita renewable energy consumption. In the long term, a 1% increase in real income per capita increases the consumption of renewable energy per capita in emerging economies by approximately 3.5%. Long-term renewable energy per capita consumption price elasticity estimates are approximately equal to -0.70.

    It is crucial that China’s renewable energy national target in 2020 is effectively decomposed into respective period targets at the provincial level. In order to resolve problems arising from combining the national and local renewable energy development plan, a total target and period target decomposition model of renewable energy is proposed which considers the resource distribution and energy consumption of different provinces as well as the development characteristics of various renewable energy industries. In the model, the total proposed target is comprised of three shares: basic share, fixed share and floating share target. The target distributed for each province is then determined by the preference relation. That is, when total renewable energy target is distributed, the central government is more concerned about resources potential or energy consumption. Additionally, the growth models for various renewable energy industries are presented, and the period targets of renewable energy in various provinces are proposed in line with regional economic development targets. In order to verify whether the energy target can be achieved, only wind power, solar power, and hydropower are considered in this study. To convenient to assess the performance of local government, the two year period is chosen as an evaluation cycle in the paper. The renewable energy targets per two-year period for each province are calculated based on the overall national renewable energy target, energy requirements and resources distribution. Setting provincial period targets will help policy makers to better implement and supervise the overall renewable energy plan. - Highlights: It is very importance that the national target of renewable energy in 2020 can be effectively decomposed into the stages target of various province. In order to resolve the relation the plan between the national and local renewable energy development planning, a total target and phase target decomposition model

    2010-01-01

    Renewable energy sources, such as wind and solar, have vast potential to reduce dependence on fossil fuels and greenhouse gas emissions in the electric sector. Climate change concerns, state initiatives including renewable portfolio standards, and consumer efforts are resulting in increased deployments of both technologies. Both solar photovoltaics (PV) and wind energy have variable and uncertain (sometimes referred to as intermittent) output, which are unlike the dispatchable sources used for the majority of electricity generation in the United States. The variability of these sources has led to concerns regarding the reliability of an electric grid that derives a large fraction of its energy from these sources as well as the cost of reliably integrating large amounts of variable generation into the electric grid. In this report, we explore the role of energy storage in the electricity grid, focusing on the effects of large-scale deployment of variable renewable sources (primarily wind and solar energy).

    For more than a decade, renewable energy certificates (RECs) have grown in use, becoming a common way to track ownership of the renewable and environmental attributes of renewable electricity generation. In recent years, however, questions have risen about the role RECs play in the decision to build new renewable energy projects. Information from a variety of market participants suggests that the importance of RECs in building new projects varies depending on a number of factors, including electricity market prices, the cost-competitiveness of the project, the presence or absence of public policies supportive of new projects, contract duration, and the perspective of different market participants. While there is no single answer to the role that RECs play, there are situations in which REC revenues are essential to project economics, as well as some where REC revenues may have little impact. To strengthen the role RECs play in both compliance and voluntary markets, there are a number of options that could be considered. In compliance markets, lawmakers or regulators would have to adopt measures that strengthen the role of RECs in the development of new projects, while in voluntary markets, it would be up to program leaders and market participants themselves to implement measures.

    The electric power sector stands at the beginning of a fundamental transformation process towards a more sustainable production based on renewable energies. Consequently, electric utilities as incumbent actors face a massive challenge to find new ways of creating, delivering, and capturing value from renewable energy technologies. This study investigates utilities' business models for renewable energies by analyzing two generic business models based on a series of in-depth interviews with German utility managers. It is found that utilities have developed viable business models for large-scale utility-side renewable energy generation. At the same time, utilities lack adequate business models to commercialize small-scale customer-side renewable energy technologies. By combining the business model concept with innovation and organization theory practical recommendations for utility mangers and policy makers are derived. - Highlights: • The energy transition creates a fundamental business model challenge for utilities. • German utilities succeed in large-scale and fail in small-scale renewable generation. • Experiences from other industries are available to inform utility managers. • Business model innovation capabilities will be crucial to master the energy transition

  19. Integration of renewable energies and nuclear power into North African Energy Systems: An analysis of energy import and export effects

    International Nuclear Information System (INIS)

    Supersberger, Nikolaus; Fuehrer, Laura

    2011-01-01

    The North African countries Morocco, Algeria, Tunisia, Libya and Egypt have been and are currently experiencing rapid growth in energy demand. This development confronts their political leaders with the question of how to expand or diversify their countries' generation capacities. In this context, renewable energies and nuclear power constitute options that have rarely been exploited so far in the region. This article analyzes the drawbacks and benefits of both alternatives, with a special focus on import and export dynamics. When attempting to make the strategic decision between renewables and atomic power, North African regional specifics and circumstances have to be taken into account. Hence, in a first step, the article characterizes the energy systems of the North African countries and presents scenarios for their future development. In a second step, it scrutinizes the energy challenges these states face in terms of domestic concerns and foreign affairs. Finally, a case study of Algeria is used to demonstrate how renewable energies, but not nuclear power, are able to respond to North African energy challenges. - Research highlights: → Using nuclear power would require fuel imports over the entire operation time. → Hence, energy exporters (Algeria, Libya) would become dependent on fuel imports. → Renewable energies can make North African countries less fuel import dependent. → Nuclear technologies would have to be imported over the whole life cycle of plants. → Domestic production for renewables technologies could be established after a first phase of technology imports.

    2007-01-01

    The Chinese government's ability to shift the energy structure towards renewable energies is now a world stake. The high weight of coal takes the economy into unsustainable growth, both at local level (SO 2 emissions) and at a global level (CO 2 emissions). But the extensive goods accumulation strategy at a pace in the region of 10% per year, prevents renewable energy sources from gaining a growing share of total consumption. On the contrary, the exponential increase in needs makes an ever-growing use of coal quite inescapable. This articles discusses the driving forces behind the energy sector and explores the high potential or renewable resources in China. (author)

    Full Text Available The new EU target of achieving 80-95% emission reductions by 2050 calls for novel energy policy solutions. Previous research has failed to evaluate the influence of all relevant elements of energy policy on technology-specific sustainable renewable energy diffusion. This paper adds to existing research by studying the effectiveness of financial and fiscal instruments on diffusion, additionally controlling for potential political, economic, social, and environmental drivers. These drivers are analysed for 26 EU countries over the period 1990-2011. The main results show that feed-in tariffs, quotas, and tenders effectively promote wind technologies. Other explanatory variables have technology- and model-dependent impacts.

    Permission to present a Bill to establish an independent commission directly responsible for the research, development and demonstration of clean, renewable, alternative sources of energy (to nuclear energy) is requested. The paragraphs of the preamble to the Bill are summarized by the Member seeking permission. The main reason for promoting renewable energy sources is opposition to the nuclear industry. One objection was raised. However, permission was granted to present the Bill and it was read for the first time with a second reading ordered for 7 March 1986. The Bill itself is not reprinted but the permission and question are reported verbatim. (U.K.)

    Kaufmann, John R.; Hand, James R.; Halverson, Mark A.

    2011-07-01

    This report evaluates how and when to best integrate renewable energy requirements into building energy codes. The basic goals were to: (1) provide a rough guide of where we’re going and how to get there; (2) identify key issues that need to be considered, including a discussion of various options with pros and cons, to help inform code deliberations; and (3) to help foster alignment among energy code-development organizations. The authors researched current approaches nationally and internationally, conducted a survey of key stakeholders to solicit input on various approaches, and evaluated the key issues related to integration of renewable energy requirements and various options to address those issues. The report concludes with recommendations and a plan to engage stakeholders. This report does not evaluate whether the use of renewable energy should be required on buildings; that question involves a political decision that is beyond the scope of this report.

  7. Renewable Energy Technology—Is It a Manufactured Technology or an Information Technology?

    Directory of Open Access Journals (Sweden)

    Kwok L. Shum

    2010-07-01

    Full Text Available Socio-technical or strategic approach to renewable energy deployment all suggests that the uptake of renewable energy technology such as solar photovoltaic is as much a social issue as a technical issue. Among social issues, one most direct and immediate component is the cost of the renewable energy technology. Because renewable electricity provides no new functionality—a clean electron does the same work as a dirty electron does—but is relatively expensive compared with fossil fuel based electricity, there is currently an under-supply of renewable electricity. Policy instruments based on economics approaches are therefore developed to encourage the production and consumption of renewable electricity, aiming to remediate the market inefficiencies that stem from the failure in internalizing the environmental or social costs of fossil fuels. In this vein, the most discussed instruments are renewable portfolio standard or quota based system and the general category of feed-in tariff. Feed-in tariff is to support output or generation of the renewable electricity by subsidizing revenues. The existing discussions have all concerned about the relative effectiveness of these two instruments in terms of cost, prices and implementation efficiency. This paper attempts a different basis of evaluation of these two instruments in terms of cost and (network externality effects. The cost effect is driven by deploying the renewable as a manufactured technology, and the network externality effect is driven by deploying the renewable as an information technology. The deployment instruments are studied in terms of how these two effects are leveraged in the deployment process. Our formulation lends itself to evolutionary policy interpretation. Future research directions associated with this new energy policy framework is then suggested.

    Energy saving and renewable energy are again on the Dutch political agenda. Based on the governmental energy report, market parties have developed the action plan for the realisation of national renewable energy targets. The evaluation of recently closed subsidy programmes and development of new incentives take place in close cooperation among governmental organisations and market parties. For the financing of the action plan the government has reserved the budget up to 2011. The government believes that the implementation of energy efficiency and renewable energy will strengthen the national economy and that the benefits of these measures will exceed the costs. The main obstacles related to the implementation of a large scale wind power generation are: spatial integration, permits and connection to the grid. Also, the large scale biomass plants meet problems because of the lack of clear environmental and sustainability criteria. The Dutch targets for 2020 are: increasing of energy efficiency with 20%, 20% renewable energy and decreasing of CO 2 -emissions with 30%.(author)

    Figures commonly quoted on costs of generating energy from renewable sources can give the impression that it will be possible to switch to renewables as the foundation for the continuation of industrial societies with high material living standards. Although renewable energy must be the sole source in a sustainable society, major difficulties become evident when conversions, storage and supply for high latitudes are considered. It is concluded that renewable energy sources will not be able to sustain present rich world levels of energy use and that a sustainable world order must be based on acceptance of much lower per capita levels of energy use, much lower living standards and a zero growth economy.

    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

    Renewable sources represent an effective alternative to fossil fuels for preventing resources depletion and for reducing air pollution. However, their diffusion requires huge capital investment and major infrastructure changes, which have to be assessed to verify their effectiveness. The article present an application of the R-MARKAL model to investigate the feasibility of renewable use on a local case study for electricity and thermal energy production. A comprehensive modelling approach is used to emphasise the relationships and feedback between conversion and demand sectors (residential, services and commercial), taking into account contemporaneously legal issues and physical limits of the system. The model's solutions represent the minimum cost choice and the results show that even in absence of erogenous environmental constraints, many renewable technologies are profitable demand device and their investment costs are paid off in a medium term by lower operating and maintenance expenditures. In this context the use of thermal energy from incinerator allows one to achieve a consistent reduction of atmospheric pollutant emissions and, particularly, of greenhouse gases emissions due to waste degradation.

    2017-09-01

    The EurObserv'ER policy profiles give a snapshot of the renewable energy policy in the EU Member States. The main support scheme to stimulate electricity from renewable energy sources is a feed-in premium scheme. RES-E project developers with installations = 10 kW have to acquire access to this scheme by submitting successful bids in tenders. Subsidies and loans can be obtained by RES-E project developers through successful applications at the Climate Change Special Programme or the Lithuanian Environmental Investment Funds (investment subsidies only). RES-E plants are exempted from excise duty. Consumers with a small PV installation can benefit from net metering. Producers of heating and cooling from renewable energy sources are exempt from environmental pollution tax and are eligible for grants. Moreover, heat suppliers are obliged to purchase all heat produced from renewable energy sources. Renewable transport fuels are promoted through reimbursement of raw materials for bio-fuel production, a bio-fuels (blending) quota scheme as well as exemption from excise tax and environmental pollution tax

    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)

    Momsen, Katharina; Stoerk, Thomas

    2014-01-01

    In energy consumption, individuals feature a gap between intention and action. Survey data from the US, the UK, and other European countries show that 50–90% of respondents favour energy from renewable sources, even at a small premium. Yet less than 3% actually buy renewable energy. We investigate how nudges – a slight change in the information set that an individual faces when taking a decision – can help individuals align behaviour with intention. We present evidence from an original survey experiment on which nudges affect the choice whether to contract renewable energy or conventional energy. We find that only a default nudge has a significant effect, while all other nudges prove ineffective. In our setting, a default nudge increases the share of individuals who choose renewable energy by 44.6%. - Highlights: • Preferences concerning renewable energy contracts do not translate into action. • Nudges are cheap policy tools, easily scaled up, coercion-free, and usually unavoidable. • We design and implement a survey experiment to test various nudges. • A default nudge proves effective in aligning intention and action

    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 of energy is stimulated by a feed-in tariff scheme which includes elements of a renewable quota scheme and tendering. Since 2011 this scheme only applies to pre-existing RES-E installations and is closed for new RES-E projects. Moreover, the present main RES-E support scheme is being evaluated which may result in reforms within short. Small-scale renewable generation, notably PV, is stimulated by net metering. On the other hand, since January 2014 a tax for subsidised electricity generators is in place. Renewable heating and cooling is promoted by fiscal instruments. To date, renewable transport fuels are promoted through a tax mechanism as well

    Koo, Bryan Bonsuk

    Electricity generation from non-hydro renewable sources has increased rapidly in the last decade. For example, Renewable Energy Sources for Electricity (RES-E) generating capacity in the U.S. almost doubled for the last three year from 2009 to 2012. Multiple papers point out that RES-E policies implemented by state governments play a crucial role in increasing RES-E generation or capacity. This study examines the effects of state RES-E policies on state RES-E generating capacity, using a fixed effects model. The research employs panel data from the 50 states and the District of Columbia, for the period 1990 to 2011, and uses a two-stage approach to control endogeneity embedded in the policies adopted by state governments, and a Prais-Winsten estimator to fix any autocorrelation in the panel data. The analysis finds that Renewable Portfolio Standards (RPS) and Net-metering are significantly and positively associated with RES-E generating capacity, but neither Public Benefit Funds nor the Mandatory Green Power Option has a statistically significant relation to RES-E generating capacity. Results of the two-stage model are quite different from models which do not employ predicted policy variables. Analysis using non-predicted variables finds that RPS and Net-metering policy are statistically insignificant and negatively associated with RES-E generating capacity. On the other hand, Green Energy Purchasing policy is insignificant in the two-stage model, but significant in the model without predicted values.

  12. Renewable Energy in Reunion: Potentials and Outlook

    2011-01-01

    Renewable, environmentally friendly and evenly distributed across the globe, renewable energy (RES for Renewable Energy Resources) is an excellent means of taking up the global energy challenge, i.e. enabling developing countries in the south to make progress without harming the environment. Since it is particularly well suited to an island territory's character and local needs, RE is also an excellent tool that could enable France's overseas Departments and Territories to reduce their energy dependence, preserve their environment and ensure their sustainable development. In Reunion, RES benefit from marked political support and from a very favourable financial and institutional environment, which has allowed the Reunion region to become a national pioneer in the realm of thermal energy and photovoltaics. Nonetheless, RES are not a panacea as they are subject to a number of flaws. It is currently expensive and uncompetitive, intermittent and insufficiently powerful, and not always available to keep up with demand. This explains why RES cannot aspire to be a complete substitute for fossil fuels. The two energy systems complement one another to meet the region's total energy needs. This article also highlights the negative consequences of the support measures for RES (inflated costs and negative prices on the electricity markets) and underscores the need for a complementary energy policy in pricing electricity, as well as effecting energy savings, which must remain our priority.

    Like many countries in Africa, Senegal is facing economical decline, energy crisis and serious desertification problem in rural areas. These issues could be removed if renewable energy is used as a primary source of energy in rural areas. What is required is a strategy to implement renewable energy technologies at large scale. The government and many non-governmental organisations (NGOs) have tried to comprehend and have strived to address the problem of energy. This paper present a review of activities in the field of renewable energy applications in Senegal, which goes back to the mid 1970s and will discuss the socio-economic benefits that the country has derived from these environmentally sound and appropriate sources of energy. The development and trial of systems were mostly funded so far by donor agencies in collaboration with government and NGOs. Among the applications being supported are solar lighting, water pumping and small power plants. Recent efforts have been aimed at restructuring the programmes and giving them a market orientation. Future trends, some suggestion and recommendations for successful dissemination of renewable energy sources are also drawn. The present situation is seen to be much more promising and favourable for renewable energy. (Author)

    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

    The IRENA Renewable Energy 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 2009 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

    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. Zusaetzlich erschwert ein drastisch gefallener Rohoelpreis die verstaerkte Nutzung des erneuerbaren Energieangebots. Ausgehend von diesen im Vergleich zu den Vorjahren verschlechterten Rahmenbedingungen werden nachfolgend die Entwicklungen in Deutschland des Jahres 2014 im Strom-, Waerme- und Transportsektor fuer den Bereich der erneuerbaren Energien aufgezeigt.

    This paper discusses some important fundamental issues behind application of renewable energy (RE) to evaluate its impact as a climate change mitigation technology. The discussed issues are the following: definition of renewable energy, concentration of RE by weight and volume, generation of electrical energy and its power at unit area, electrical energy demand per unit area, life time approach vs. layman approach, energy return time, energy return ratio, CO2 return time, energy mix for RES production and use, geographical distribution of RES use, huge scale of energy shift from RES to non-RES, increase in energy consumption, Thermodynamic equilibrium of earth, and probable solutions for energy future of our energy and environmental crisis of today. The future solution (that would enable to human civilization further welfare, and good living, but with lower release of CO2 in atmosphere) may not be only RES. This will rather be an energy mix that may contain nuclear energy, non-nuclear renewable energy, or fossil energy with CO2 sequestration, efficient energy technologies, energy saving, and energy consumption decrease.

    This paper provides a comprehensive database of renewable energy facilities in Canada by province and by resource type. It considers technologies used for power generation or cogeneration, renewable energy heating systems, hydrogen generation and transportation fuels. Renewable energy technologies convert naturally regenerating resources into useful energy such as electricity, thermal energy, hydrogen or bio-fuels. The database contains information on renewable power operations in Canada over a scale of 100 kilowatts of rated capacity. Smaller applications have been included for run-of-river, hydro, earth, wind and solar power. There are 753 records for renewable energy facilities in Canada, including wind, hydroelectricity, wood residue biomass, landfill/sewage gas, solar photovoltaic, municipal solid waste, and tidal energy. The data in this report was acquired from Statistics Canada and other public information sources. For each of the 753 renewable energy power plants, this report states its type of renewable energy, the province, the name of the project, its location, its operator, electrical generating capacity, number of generating units, average annual electricity production, and the year it began operation. Canada currently has an installed electrical capacity of 115 GW, of which renewable energy sources constitute 76 per cent with the dominant source being hydroelectricity. Manitoba has the highest portion of renewable energy in its installed electrical capacity. Approximately 40 per cent Canada's renewable power capacity is in Quebec, followed by 15 per cent in British Columbia. Nova Scotia has Canada's only tidal power plant. Most of the installed renewable energy power capacity in Canada is owned by integrated electric utilities and a small percentage is owned by renewable electricity generating companies, aluminium companies, pulp and paper companies or diversified electricity generators. It is expected that interest in renewable energy will grow with

    The current discussion of climate change and energy problems is generally based on the assumption that technical solutions are possible and that the task is essentially to determine the most effective ways. This view relies heavily on the expectation that renewable energy sources can be substituted for fossil fuels. Australia is more favourably situated regarding renewable sources than almost any other country. This discussion attempts to estimate the investment cost that would be involved in deriving Australia's total energy supply from renewable sources. When provision is made for intermittency and plant redundancy it is concluded that the total investment cost is likely to be unaffordable. - Highlights: ► The capacity of renewable energy to meet Australia's probable 2050 demand is assessed. ► Assumptions re output and capital cost for wind, PV, biomass and solar thermal are established. ► Capacity to cope with energy storage, intermittency, storage and redundancy is estimated. ► A total 2050 capital cost is derived. ► It is concluded that the capital cost would be unaffordable.

    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.

    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)

In partnership with the Oregon Military Department, the Department of Energy used the award to assess and evaluate renewable resources in a 2,622-acre location in Lake County, central Oregon, leading to future development of up to 200 MW of solar electricity. The Oregon Military Department (Military) acquired a large parcel of land located in south central Oregon. The land was previously owned by the US Air Force and developed for an Over-the-Horizon Backscatter Radar Transmitter Facility, located about 10 miles east of the town of Christmas Valley. The Military is investigating a number of uses for the site, including Research and Development (R&D) laboratory, emergency response, military operations, developing renewable energy and related educational programs. One of the key potential uses would be for a large scale solar photovoltaic power plant. This is an attractive use because the site has excellent solar exposure; an existing strong electrical interconnection to the power grid; and a secure location at a moderate cost per acre. The project objectives include: 1. Site evaluation 2. Research and Development (R&D) facility analysis 3. Utility interconnection studies and agreements 4. Additional on-site renewable energy resources analysis 5. Community education, outreach and mitigation 6. Renewable energy and emergency readiness training program for veterans

    Fossil fuel reserves are diminishing rapidly across the world. Greenhouse gas emissions, climatic changes and global warming have a direct impact on the environment. A secure and accessible supply of energy is very crucial for the sustainability of modern societies. There is an urgent need for a quicker switch over of energy systems from conventional to renewable that are sustainable and can meet the present and projected world energy demand. Renewable energy has a large potential to become the fuel of the future. The present study is aimed to explore such potential and achievements in India. India is expected to have high growth rate in energy demand over the coming years due to its huge population and rapid economic development. The renewable energy prospects/spectrums of India have been highlighted. (author)

    The existence of a great number of inhabitants without electricity, living in areas of low population density, with modest energy requirements and low income provides a major potential market for decentralized renewable energy sources. Ademe and EDF in 1993 made two agreements concerning the development of Renewable Energy Sources. The first aims at promoting their decentralized use in France in pertinent cases. The second agreement concerns other countries and has two ambitions: facilitate short-term developments and produce in the longer term a standardised proposal for decentralized energy production using Renewable Energy Sources to a considerable extent. These ideas are explained, and the principles behind the implementation of both Ademe-EDF agreements as well as their future prospects are described. (R.P.)

    REN21's Renewables 2018 Global Status Report presents developments and trends through the end of 2017, as well as observed trends from early 2018 where available. Renewable power accounted for 70% of net additions to global power generating capacity in 2017, the largest increase in renewable power capacity in modern history, according to REN21's Renewables 2018 Global Status Report (GSR). But the heating, cooling and transport sectors - which together account for about four-fifths of global final energy demand - continue to lag far behind the power sector. The GSR, published today, is the most comprehensive annual overview of the state of renewable energy worldwide. New solar photovoltaic (PV) capacity reached record levels: Solar PV additions were up 29% relative to 2016, to 98 GW. More solar PV generating capacity was added to the electricity system than net capacity additions of coal, natural gas and nuclear power combined. Wind power also drove the uptake of renewables with 52 GW added globally. Investment in new renewable power capacity was more than twice that of net, new fossil fuel and nuclear power capacity combined, despite large, ongoing subsidies for fossil fuel generation. More than two-thirds of investments in power generation were in renewables in 2017, thanks to their increasing cost-competitiveness - and the share of renewables in the power sector is expected to only continue to rise. Investment in renewables was regionally concentrated: China, Europe and the United States accounted for nearly 75% of global investment in renewables in 2017. However, when measured per unit of gross domestic product (GDP), the Marshall Islands, Rwanda, the Solomon Islands, Guinea Bissau, and many other developing countries are investing as much as or more in renewables than developed and emerging economies. Both energy demand and energy-related CO 2 emissions rose substantially for the first time in four years. Energy-related CO 2 emissions rose by 1

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

    Markard, Jochen; Truffer, Bernhard

    2006-01-01

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

    The sudden surge of growth which has occurred in the renewable energy industry over the past five years has caught educators napping. Utilities and industry are finding it difficult to recruit staff who are qualified to design and maintain renewable energy systems. The Australian Cooperative Research Centre for Renewable Energy (ACRE), established in July 1996, is committed to addressing the social and environmental issues raised by global warming by developing and commercializing high quality renewable energy systems. A crucial part of this mission is to provide educational services to support this new technology and to build public confidence in renewable energy systems. The Education Program of ACRE will provide a range of education, training and information about renewable energy systems and greenhouse issues. This paper describes the approach and objectives of the Education Program and the outcomes it hopes to achieve. (author). 5 refs.

    The major technological developments in equipment, designed to harness new and renewable sources of energy, have only taken place in the last four decades of the twentieth century, although the principles involved have been previously known for many centuries and were clearly formulated in many of the ancient civilizations. The term renewable energy (RE) itself is of relatively recent origin and only came into widespread use worldwide in the eighties, after the United Nations Conference on New and Renewable Sources of Energy, held in Nairobi, Kenya in 1981, Ref 1. Currently, the term renewable s is extensively used to describe the full range of direct and indirect uses of solar radiation incident on the earth's surface, and is often extended to include energy resources, such as tidal power or geothermal energy, neither of which is strictly renewable in the true sense of the word. Energy extracted from biomass is also generally included under this heading, although biomass is truly renewable only if continuous plantation development and replanting is carried out as the biomass is harvested. On a global scale, relatively extensive teaching about renewable energy started in the late seventies and early eighties, after the first impact of the OPEC oil price shock. Up till this time, there were only a few centres around the world where individual dedicated researchers and university teachers were involved in such activity. The next impetus to course and teaching material development came with national movements for energy independence and finally, in the latter years of this century, considerable stimulation has been given due to the increasing realisation of global environmental factors such as global warming, ozone depletion in the upper atmosphere, acid rain formation, and many other environmental degradation effects due to the increasing use of fossil fuel reserves. Considerable attention has been focused in the last twenty years through the many national and

    The U.S. Department of Energy (DOE) recognizes the need to transform the energy infrastructure of the U.S. and elsewhere to systems that can drastically reduce environmental impacts in an efficient and economically viable manner while utilizing both hydrocarbon resources and clean energy generation sources. Thus, DOE is supporting research and development that could lead to more efficient utilization of clean energy generation sources, including renewable and nuclear options. A concept being advanced by the DOE Offices of Nuclear Energy (NE) and Energy Efficiency and Renewable Energy (EERE) is tighter coupling of nuclear and renewable energy sources in a manner that produces new energy currency for the combined electricity grid, industrial manufacturing, and the transportation energy sectors. This integration concept has been referred to as a “hybrid system” that is capable of providing the right type of energy, at the right time, in the right place. At the direction of DOE-NE and DOE-EERE leadership, project leads at Idaho National Laboratory (INL), National Renewable Energy Laboratory (NREL) and Massachusetts Institute of Technology (MIT) have identified and engaged stakeholders in discussing integrated energy systems that would optimize renewable and nuclear energy integration on a region-by-region basis. Subsequent work will entail conduct of technical, economic, environmental and socio-political evaluations of the leading integrated system options based on a set of criteria established with stakeholder input. The Foundational Workshop for Integrated Nuclear – Renewable Energy Systems was organized around the following objectives: 1. Identify and refine priority region-specific opportunities for integrated nuclear-renewable energy systems in the U.S.; 2. Select Figures of Merit (FOM) to rank and prioritize candidate systems; 3.

    This presentation provides an overview of international voluntary renewable energy markets, with a focus on the United States and Europe. The voluntary renewable energy market is the market in which consumers and institutions purchase renewable energy to match their electricity needs on a voluntary basis. In 2010, the U.S. voluntary market was estimated at 35 terawatt-hours (TWh) compared to 300 TWh in the European market, though key differences exist. On a customer basis, Australia has historically had the largest number of customers, pricing for voluntary certificates remains low, at less than $1 megawatt-hour, though prices depend on technology.

    In order to reduce the state deficit the French government plans to reduce the financial incentives in all sectors and particularly in the sector of renewable energies. The photovoltaic sector is the most hit with a tax credit rate dropping from 50% (in 2009) to 22.5% (in 2011). For the other renewable energy sectors the tax credit rate will be reduced by 10% in 2011. The French government wants the cost of the tax credit on the renewable energies to drop from 2.8*10 9 euros in 2009 to 2.0*10 9 euros in 2011. (A.C.)

  4. Renewable energy sources and Estonian national interests

    There is only one national level document, The Long-term National Development Plan for the Fuel and Energy sector, regulating the development of renewable energy for Estonia. It was approved by the Parliament (Riigikogu) in 1998. This document planned a 2/3 (66,7%) increase in the share of renewable (according to the document: peat, biofuels and other renewables) to the year 2010 against 1996. At the same time a decrease of the share of domestic oil shale was planned 1/5 to the year 2010 against 1995. That means the use of domestic energy sources, both renewable and non-renewable, will decrease by 16,8% altogether. In reality the rapid projected growth of renewables in Estonia (+66,7% between 1996 and 2010) was changed with decrease of 20% by 2000. So the security of supply must shift to the first place in Estonia. It is also an issue of national sovereignty. Estonia is rich in renewable energy sources, mainly in wood, peat and wind, to achieve the goals set in the National Development Plan. Forest resources amount 352,7, total felling 6,44, allowed felling 7,81 million cubic meters solid volume in 2000. The future of fuel peat usage in Estonia is uncertain, as most of the EU member states, which have burned up their peat resources and/or drained their mires do not consider peat as a renewable fuel. Obviously Estonia has to explain its opinion about the renewability of its resources. Although progress is needed in all directions of additional use of all renewable energy sources in tactical consideration finance must be directed first to guarantee better use of wastes of woodworking and timber industry

    Besides energy conservation, the exploration of renewable energy sources, in particular biomass and solar energy, are central aspects of the Austrian energy policy, regarded as an optimal option for achieving CO2-emission reduction objectives. The market penetration of Renewable Energy Technologies in the last twenty years was supported by the Austrian Energy Research Programme. The result of successful developments of biomass heating, solar thermal, solar electrical and wind energy technologies is the key for the market development of these renewable energy technologies. With the market penetration of renewable energy technologies new business areas were established and employment created. Today, some renewable energy technologies in Austria have reached economic competitiveness. Some technologies not reached commercialisation, and need more development to improve efficiency, reliability and cost to become commercial. This would include material and system development, pilot plants or field experiments to clarify technical problems, and demonstration plants to illustrate performance capabilities and to clarify problems for commercialisation

    A comprehensive analysis, region by region, of the actually accessible renewable energies at a given horizon, is presented. The same methodology as the one employed to derive ``proven fossil energy reserves`` from ``energy resources`` is adopted, in which resources are defined by quantitative information on physical potential, while reserves take into account technical and economical accessibility. As renewable resources are fluctuating with time and are diluted in space and not readily transportable or storeable, it is necessary to consider the presence of populations or activities near enough to be able to profit by these diluted and volatile energies.

    The article examines the influence of renewable energy companies on the decision-making process related to the German energy transition. It identifies clusters of different lobbying activities and styles through in depth interviews with 20 stakeholders from policy-making and business. The research used Repertory Grid Technique in combination with HOMALS multivariate analysis. Its main findings are: First, although the big four electric utilities operating on the German energy market still possess wide influence, companies of renewable energy have developed from a niche into important players of the energy regime. Second, lobbies by the renewable energy sector are mainly aimed at the legislative framework, particularly on the Renewable Energy Sources Act and the feed-in-system. Third, interviewees identified 36 different lobby activities; the most effective ones are: ‘Regular and personal maintenance of contact to politicians’, ‘Lobbying within an association’, ‘Knowledge development with correct information’ and ‘Top-down contacting of most powerful politicians’. Fourth, the statistical analysis reveals clear distinctions between companies with regards to their lobby strategies which are evaluated differently by stakeholders. Finally, the article concludes that companies have a strong influence on political-decision making and – together with governmental actors – form a ‘policy network’ that strongly shapes the German energy transition

    We are building a multidisciplinary research program linking researchers in agriculture, business, earth science, engineering, humanities and social science. Our goal is to match renewable energy supply and reformed energy demands. The program will be focused on (i) understanding and modifying energy demand, (ii) design and implementation of diverse renewable energy networks. Geomatics technology will be used to map existing energy and waste flows on a neighbourhood, municipal, and regional level. Optimal sites and combinations of sites for solar and wind electrical generation (ridges, rooftops, valley walls) will be identified. Geomatics based site and grid analyses will identify best locations for energy production based on efficient production and connectivity to regional grids and transportation. Design of networks for utilization of waste streams of heat, water, animal and human waste for energy production will be investigated. Agriculture, cities and industry produce many waste streams that are not well utilized. Therefore, establishing a renewable energy resource mapping and planning program for electrical generation, waste heat and energy recovery, biomass collection, and biochar, biodiesel and syngas production is critical to regional energy optimization. Electrical storage and demand management are two priorities that will be investigated. Regional scale cooperatives may use electric vehicle batteries and innovations such as pump storage and concentrated solar molten salt heat storage for steam turbine electrical generation. Energy demand management is poorly explored in Canada and elsewhere - our homes and businesses operate on an unrestricted demand. Simple monitoring and energy demand-ranking software can easily reduce peaks demands and move lower ranked uses to non-peak periods, thereby reducing the grid size needed to meet peak demands. Peak demand strains the current energy grid capacity and often requires demand balancing projects and

    According to Shell, by 2050, renewable energy sources may supply over 50% of the energy, worldwide. This concentration on renewable energy sources is primarily due to the intensified environmental demands. The UN climate panel has estimated that to avoid irreversible climate change it is necessary to reduce the global emissions of CO2 by 50 to 60% during the next 100 years. Biomass energy includes a number of biological raw materials from forestry and agriculture. The forests provide wood, wood chips, bark, branches and treetops, and from agriculture, straw. Although biomass energy is not entirely pollution-free, it is renewable and CO2-neutral as long as growth and consumption are in balance. In Norway, the total annual growth of available biomass corresponds to about 80 TWh. The technical potential is estimated to 30 TWh per year, allowing for operationally reasonable ways of producing the biomass. However, there is competition for the biomass since it is used by the wood processing industry. The use of biomass and waste for energy generation varies considerably among the Nordic countries. In Denmark, agriculture dominates and large quantities of straw are burned in cogeneration plants. Sweden and Finland have well-developed forest industries, and the wood processing industry in these countries uses much more biomass fuel (bark, fibre mud, black liquor) than the Norwegian wood processing industry. In Norway, more energy can be obtained by retrofitting old hydroelectric plants such as by installing a flexible liner in existing tunnels. This improves energy flexibility and increases energy production without negative environmental consequences. The potential for wind power is larger in Norway than in Denmark and Germany. The cost of wind power has fallen considerably as a consequence of the technological development of the sector

    Most of the countries around the world have realized that the key to attaining and maintaining prosperity and sovereignty is having independence and self-reliance in access to and subsequent use of energy. To address the global challenges, the energy system needs to undergo a transformation from fossil-fuels to renewable energy and energy efficient technologies. Pakistan has a huge potential for harnessing renewable energy and its share in the electricity mix has to be increased to achieve energy security. Security issues and circular debt in the country are the key challenges that need to be addressed to promote on-grid renewable energy through private sector. Around 38 % of the total Pakistani population remains without access to electricity. Fifty four per cent of the rural population currently has no access to electricity, forcing them to live a sub-standard life of poverty and social inequity. Microfinance and other innovative financial tools need to be evolved to promote rural electrification through renewable energies. (author)

    Renewable energy sources and technologies have potential to provide solutions to the long-standing energy problems being faced by the developing countries. The renewable energy sources like wind energy, solar energy, biomass energy and fuel cell technology can be used to overcome energy shortage in India. To meet the energy requirement for such a fast growing economy, India will require an assured supply of 3-4 times more energy than the total energy consumed today. The renewable energy is one of the options to meet this requirement. India is increasingly adopting responsible renewable energy techniques and taking positive steps towards carbon emissions, cleaning the air and ensuring a more sustainable future. In India, from the last two and half decades there has been a vigorous pursuit of activities relating to research, development, demonstration, production and application of a variety of renewable energy technologies for use in different sectors. In this paper, efforts have been made to summarize the availability, current status, major achievements and future potentials of renewable energy options in India. This paper also assesses specific policy interventions for overcoming the barriers and enhancing deployment of renewable energy devices for the future. (author)

    The challenge of transforming entire economies is enormous, especially if a country is as fossil- fuel-based and emission-intensive as South Africa. However, as it is already facing climate change impacts in an increasingly carbon-constrained world, South Africa must drastically reduce its greenhouse gas emission intensity soon. The South African electricity sector is a vital part of the economy and at the same time contributes most to the emission problem. Transforming this sector is therefore urgently needed, but will be difficult. First steps have been taken to enhance energy efficiency and promote renewable energy, but they have failed to have any large-scale effects. The two major barriers to investments in renewable energy technologies are based in the South African energy innovation system and its inherent power structures and in the economics of renewable energy technologies. The innovation system is dominated by the state-owned Eskom (electricity) and Sasol (fuel) enterprises. Both companies have their core competencies in fossil fuel technologies. Capacity in renewable energy is lacking at every stage of the technology cycle, from research and development to installation and maintenance. The obstacles inherent in the economics of renewable energy technologies are cost and risk, two of the main factors in investment planning. As most technologies are in early stages of development, they have not yet realized their full cost degression potential and continue to entail a higher risk than established technologies. To overcome these barriers, the South African government has introduced several renewable energy support measures, such as a renewable energy feed-in tariff (REFIT). While a promising scheme in theory, the South African REFIT has a crucial flaw: Eskom is the monopsonistic buyer of electricity produced from renewable energy and is responsible for distributing it to consumers. However, Eskom is not obliged to buy that electricity. This runs counter to

    Full Text Available The authors consider main characteristics of modern development of renewable energy sources (RES. It is dedicated that there are some technical and economic barriers to the widespread use of renewable energy. For example, RES are inconstancy in time and space and have low density of energy flow. High capital intensity and cost price, long-term construction, a considerable degree of different kinds of risk, lack of competitiveness with hydrocarbon species generation in the existing regulatory environment are also inherent to RES. The role of the regulatory framework is shown according to perspective plans of construction of power plants using renewable energy sources. The main requirements which are applied to measures of state support of construction industry of renewable energy development are formulated. Current condition of construction industry of RES in Russia is assessed. The problems of risks which arise during construction of renewable energy facilities according to results of practical use of RES are discussed. And it is rather important to use stage assessment for the construction phase of the project during risk analysis of construction of alternative energy sources. The main groups of RES risks are described. The importance of regulatory and resource risks for effective development of renewable energy in Russia according to the method of strategic planning with the identification of the adverse effects of gradation factors are determined. The analysis of financial risks types and methods of its management during construction power generation projects based on different types of renewable energy resources are made. In the end of the article the authors make a conclusion, that the development of projects for the construction of power plants with the use of innovative technical solutions to ensure minimal risks to the environment and safe operation in various climatic conditions is a priority.

    The costs of electric power projects utilizing renewable energy technologies are highly sensitive to financing terms. Consequently, as the electricity industry is restructured and new renewables policies are created, it is important for policymakers to consider the impacts of renewables policy design on project financing. This report describes the power plant financing process and provides insights to policymakers on the important nexus between renewables policy design and finance. A cash-flow model is used to estimate the impact of various financing variables on renewable energy costs. Past and current renewable energy policies are then evaluated to demonstrate the influence of policy design on the financing process and on financing costs. The possible impacts of electricity restructuring on power plant financing are discussed and key design issues are identified for three specific renewable energy programs being considered in the restructuring process: (1) surcharge-funded policies; (2) renewables portfolio standards; and (3) green marketing programs. Finally, several policies that are intended to directly reduce financing costs and barriers are analyzed. The authors find that one of the key reasons that renewables policies are not more effective is that project development and financing processes are frequently ignored or misunderstood when designing and implementing renewable energy incentives. A policy that is carefully designed can reduce renewable energy costs dramatically by providing revenue certainty that will, in turn, reduce financing risk premiums.
