  3. Renewable Energy Prices in State-Level Feed-in Tariffs: Federal Law Constraints and Possible Solutions

    Energy Technology Data Exchange (ETDEWEB)

    Hempling, S.; Elefant, C.; Cory, K.; Porter, K.

    2010-01-01

    State legislatures and state utility commissions trying to attract renewable energy projects are considering feed-in tariffs, which obligate retail utilities to purchase electricity from renewable producers under standard arrangements specifying prices, terms, and conditions. The use of feed-in tariffs simplifies the purchase process, provides revenue certainty to generators, and reduces the cost of financing generating projects. However, some argue that federal law--including the Public Utility Regulatory Policies Act of 1978 (PURPA) and the Federal Power Act of 1935 (FPA)--constrain state-level feed-in tariffs. This report seeks to reduce the legal uncertainties for states contemplating feed-in tariffs by explaining the constraints imposed by federal statutes. It describes the federal constraints, identifies transaction categories that are free of those constraints, and offers ways for state and federal policymakers to interpret or modify existing law to remove or reduce these constraints. This report proposes ways to revise these federal statutes. It creates a broad working definition of a state-level feed-in tariff. Given this definition, this report concludes there are paths to non-preempted, state-level feed-in tariffs under current federal law.

    This final report published by the Swiss Federal Office of Energy (SFOE) presents a review of possible systems that could be used to promote power production in Switzerland using renewable energy sources. Promotional models on both the provider and consumer sides that use both price and quantity as control factors are examined. Three models are compared: the submission-to-tender model, the quota model with certificates and a model that uses cost-based feed-in tariffs. On the basis of a comparison with Austria, interaction between increasing the proportion of renewable forms of energy and the realisation of energy-efficiency goals is discussed. A further part of the report deals with various options for the use of biomass as a source of energy.

    As a Global Environment Facility (GEF) founding implementing agency, UNDP has worked on over 230 GEF-supported clean energy projects in close to 100 developing countries since 1992. About 100 of these projects in 80 countries have focused on renewable energy, supported by approximately US $ 293 million in GEF funds and leveraging US $1.48 billion in associated co-financing from national governments, international organizations, the private sector and non-governmental organizations. As part of UNDP efforts to codify and share lessons learnt from these initiatives, this report addresses how scarce public resources can be used to catalyze larger private financial flows for renewable energy. It provides an overview of UNDP-GEF’s extensive work supporting development of national renewable energy policies such as feed-in tariffs. In these activities UNDP-GEF assists developing countries to assess key risks and barriers to technology diffusion and then to identify a mix of policy and financial de-risking measures to remove these barriers and drive investment. This approach is illustrated through three case studies in Uruguay, Mauritius and Kazakhstan. This report is complemented by a companion publication presenting an innovative UNDP financial modeling tool to assist policymakers in appraising different public instruments to promote clean energy.

    In Germany, the electricity generation from renewable energy has been promoted since the year 2000 by a feed-in tariff system, the Renewable Energy Sources Act (EEG). This article evaluates the long-term impact of the German feed-in tariffs on the development of the German energy system with the help of the energy system model TIMES-D. In the model-based analysis, both the payment side (i.e. the tariffs) and the cost side (i.e. the EEG apportionment) are taken into consideration. Through the promotion of the feed-in tariff system - in combination with the European Emission Trading Scheme (ETS) - the use of renewable energies in electricity generation in Germany rises considerably such that renewable energy sources account for almost 40% of total gross electricity consumption in 2030. Accordingly, until 2020 total EEG fee payments as well as the EEG apportionment increase significantly. The impact of the feed-in tariff system on final electricity demand is, however, relatively small. Alternative scenario settings show that the expansion of the renewable electricity generation through the feed-in tariff system clearly exceeds the development which would occur when trying to reach the reduction targets of the ETS in a cost-efficient way.

    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.

    This multidisciplinary research is focused on studying implementation of diverse renewable energy networks. Our modern economy now depends heavily on large-scale, energy-intensive technologies. A transition to low carbon, renewable sources of energy is needed. We will develop a procedure for designing and analyzing renewable energy systems based on the magnitude, distribution, temporal characteristics, reliability and costs of the various renewable resources (including biomass waste streams) in combination with various measures to control the magnitude and timing of energy demand. The southern Canadian prairies are an ideal location for developing renewable energy networks. The region is blessed with steady, westerly winds and bright sunshine for more hours annually than Houston Texas. Extensive irrigation agriculture provides huge waste streams that can be processed biologically and chemically to create a range of biofuels. The first stage involves mapping existing energy and waste flows on a neighbourhood, municipal, and regional level. Optimal sites and combinations of sites for solar and wind electrical generation, such as ridges, rooftops and 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.

    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

    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.

    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. Favourable power energy purchasing prices are set for renewable energy sources and small cogeneration plants

    Full Text Available Energy production based on fossil fuel reserves is largely responsible for carbon emissions, and hence global warming. The planet needs concerted action to reduce fossil fuel usage and to implement carbon mitigation measures. Ocean energy has huge potential, but there are major interdisciplinary problems to be overcome regarding technology, cost reduction, investment, environmental impact, governance, and so forth. This article briefly reviews ocean energy production from offshore wind, tidal stream, ocean current, tidal range, wave, thermal, salinity gradients, and biomass sources. Future areas of research and development are outlined that could make exploitation of the marine renewable energy (MRE seascape a viable proposition; these areas include energy storage, advanced materials, robotics, and informatics. The article concludes with a sustainability perspective on the MRE seascape encompassing ethics, legislation, the regulatory environment, governance and consenting, economic, social, and environmental constraints. A new generation of engineers is needed with the ingenuity and spirit of adventure to meet the global challenge posed by MRE.

    Renewable energy is now a mainstream concern among businesses and governments across the world, and could be considered a characteristic preoccupation of our time. It is interesting to note that many of the energy technologies currently being developed date back to very different eras, and even predate the industrial revolution. The fuel cell was first invented as long ago as 1838 by the Swiss--German chemist Christian Friedrich Schönbein [1], and the idea of harnessing solar power dates back to ancient Greece [2]. The enduring fascination with new means of harnessing energy is no doubt linked to man's innate delight in expending it, whether it be to satisfy the drive of curiosity, or from a hunger for entertainment, or to power automated labour-saving devices. But this must be galvanized by the sustained ability to improve device performance, unearthing original science, and asking new questions, for example regarding the durability of photovoltaic devices [3]. As in so many fields, advances in hydrogen storage technology for fuel cells have benefited significantly from nanotechnology. The idea is that the kinetics of hydrogen uptake and release may be reduced by decreasing the particle size. An understanding of how effective this may be has been hampered by limited knowledge of the way the thermodynamics are affected by atom or molecule cluster size. Detailed calculations of individual atoms in clusters are limited by computational resources as to the number of atoms that can studied, and other innovative approaches that deal with force fields derived by extrapolating the difference between the properties of clusters and bulk matter require labour-intensive modifications when extending such studies to new materials. In [4], researchers in the US use an alternative approach, considering the nanoparticle as having the same crystal structure as the bulk but relaxing the few layers of atoms near the surface.

    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.

    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)

  7. World potential of renewable energies

    Energy Technology Data Exchange (ETDEWEB)

    Dessus, B.; Devin, B.; Pharabod, F.

    1991-07-01

    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.

    This paper illustrates the effect that can be observed when support schemes for renewable energy are regionalised. Two theoretical examples are used to explain interactive effects on, e.g., the price of power, conditions for conventional power producers, and changes in import and export of power...... RES-E support schemes already has a common liberalised power market. In this case the introduction of a common support scheme for renewable technologies will lead to more efficient sitings of renewable plants, improving economic and environmental performance of the total power system...

    1995-12-31

    On June 25--27, 1995, at Mesa Verde National Park in southwestern Colorado, the Center for Resource Management (CRM), organized and sponsored a conference in conjunction with the Navajo Nation, EPA, and Bechtel Group, Inc., to deal with issues associated with developing renewable energy resources on Indian lands. Due to the remoteness of many reservation homes and the cost of traditional power line extensions, a large percentage of the Indian population is today without electricity or other energy services. In addition, while they continue to develop energy resources for export, seeing only minimal gain in their own economies, Indian people are also subject to the health and environmental consequences associated with proximity to traditional energy resource development. Renewable energy technologies, on the other hand, are often ideally suited to decentralized, low-density demand. These technologies--especially solar and wind power--have no adverse health impacts associated with generation, are relatively low cost, and can be used in applications as small as a single home, meeting power needs right at a site. Their minimal impact on the environment make them particularly compatible with American Indian philosophies and lifestyles. Unfortunately, the match between renewable energy and Indian tribes has been hampered by the lack of a comprehensive, coordinated effort to identify renewable energy resources located on Indian lands, to develop practical links between Indian people`s needs and energy producers, and to provide the necessary training for tribal leaders and members to plan, implement, and maintain renewable energy systems. Summaries of the presentations are presented.

    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)

    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.

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

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.

The authorities wished to form this support as a feed-in arrangement, something which means that all projects qualified for the support will receive the same compensation per kWh (possibly differentiated between technologies). A scheme like this can be formed in several ways. A model where the support is given as a constant mark-up in the power price will give the highest socio-economic effect. Moreover, such a model is well suited if the scheme is to be financed by a fund and managed by Enova SF. Models with guaranteed or minimum prices exposes Enova for the risk of power prices and will give large variations in the yearly disbursals. The scheme can be made technology neutral or differentiate between technologies depending on which goals are prioritised. A prioritising mechanism must also be introduced since the framework for the collective support is limited by the return of the fund (ml)

    Renewable energy sources and distributed generation will play a key role in transforming the power grid of the future. This presentation discussed some of the key renewable sources that General Electric (GE) is involved in, including wind, solar and biomass. Distributed generation has become an efficient and clean alternative to traditional power generation systems. It reduces transmission and distribution system losses while providing enhanced service reliability and quality, improved voltage regulation, and transmission and distribution system congestion relief. This presentation focused on some of the technical challenges and grid interconnection issues that could affect the penetration of such distributed generation systems. GE is developing a controller that manages the complex interactions in a micro grid. The controller combines on-site power generation and stored energy, allowing the micro grid to both function as an isolated unit, making and using its own energy, or interacting with the larger-scale grid to which it is connected. The presentation also made reference to some of the renewable energy demonstration programs that GE was actively pursuing.

    The energy sector in Lebanon plays an important role in the overall development of the country, especially that it suffers from many serious problems. The fact that Lebanon is among the few countries that are not endowed with fossil fuels in the Middle East made this sector cause one third of the national debt in Lebanon. Despite the large government investments in the power sector, demand still exceeds supply and Lebanon frequently goes through black out in peak demand times or has to resort to importing electricity from Syria. The Energy production sector has dramatic environmental and economical impacts in the form of emitted gasses and environment sabotage, accordingly, it is imperative that renewable energy (RE) be looked at as an alternative energy source. Officials at the Ministry of Energy and Water (MEW) and Lebanese Electricity (EDL) have repeatedly expressed their support to renewable energy utilization. So far, only very few renewable energy applications can be observed over the country. Major efforts are still needed to overcome this situation and promote the use of renewable energy. These efforts are the shared responsibility of the government, EDL, NGO's and educational and research centers. Additionally, some efforts are being made by some international organizations such as UNDP, ESCWA, EC and other donor agencies operating in Lebanon. This work reviews the status of Energy in Lebanon, the installed RE projects, and the potential projects. It also reviews the stakeholders in the field of RE in Lebanon Conclusion In considering the best R.E. alternative, it is important to consider all potential R.E. sources, their costs, market availability, suitability for the selected location, significance of the energy produced and return on investment. Several RE resources in Lebanon have been investigated; Tides and waves energy is limited and not suitable two tentative sites for geothermal energy are available but not used.

  6. Promotion of Renewable Energy Sources in the European Union

    Directory of Open Access Journals (Sweden)

    Roland Menges

    2015-10-01

    Full Text Available One of the important goals of European energy policy is to increase the share of renewable energy resources in the energy supply. The instruments used in the member states are not fully compatible with the rules of the European internal market. In a theoretical section, this paper analyses possible different instruments for promoting renewable energy. Some countries use feed in tariffs - using fixed prices to increase incentives for producers to invest into renewable energy, other countries use quantity-based systems like quotas that lead to a premium above the market price. In an institutional analysis we show that on the basis of effectiveness and efficiency considerations for the European Union, in the long-term quantity oriented systems of promotion are preferable if combined with elements of a capacity market. The main reason for this conclusion is that price-based systems cannot give enough incentives for backup capacities necessary to cope with intermittent production of renewable sources. In addition price-based systems violate the basic rules of the open internal European market because feed in tariffs are a considerable barrier for trade of renewable energy products.

    2001-11-01

    Renewable energy resources in the Syrian Arab Republic are surveyed. Potential of solar, wind and bio-mass resources and their promising applications are analyzed. The annual average long-term solar radiation on a horizontal plane is measured and found to be 5.2 kWh/m{sup 2} per day. Wind speed measurements were conducted in more than twenty stations spread all over the country. The prospects of these measurements indicate that wind is another promising source of renewable energy in Syria. The registered annual mean daily wind speed in some regions of the country reaches more than 13 m/sec. Theoretical study estimates that the bio-gas production of the daily wastes of humans, animals and agriculture is higher than 300 million cubic meters per year. (Author)

    Rowe, W. D.

    1982-02-01

    The possibilities of various renewable energy technologies to supply a projected world demand for 40,000 GW years of energy each year by the year 2050 are examined. Noting that industrial processes consume 50% of all energy needs, fossil fuel reserves are shown to be sufficient for a maximum of 370 yr in the U.S., when all supplies become depleted. Breeder reactors have a doubling time which is 30 yr too long for meeting more than 0.5% of world energy demand in 2050, while fusion, even considering ocean-derived deuterium as a fuel source, will not be supplying energy for another 35-70 yr. Among the solar technologies, the installation of ten million 100 m tall 4 MW wind generators is feasible to meet all the projected energy needs, and solar cells with 10% conversion efficiency could do the same with 14 times less land. Further discussion is given to geothermal, fuel cell, and OTEC technologies, as well as the forty trillion dollars necessary to erect the fully renewable systems.

    Kumar, C.

    2010-07-01

    Generators for renewable energy applications were discussed in this presentation. These applications included: hydel, wind, biomass, and solar thermal. Generators can be designed and manufactured to match the type of prime movers and their characteristics with basic design experience in the rotating electrical machines. Though the output power with these renewable systems range from small kilowatts to megawatts, the controls systems required are quite different depending on the site and the type of customers. There are many types of generators, including synchronous or asynchronous generators, or those with or without permanent magnets. They could also be with controls or without controls and with the grid or without the grid. They could also be slow speed or high speed; direct coupled or indirect; or single or dual or DFIG systems. Most of the generators being used are designed as generators meant for the specific prime movers characteristics. In many cases prime mover alone are not designed for prime mover applications.

    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.

    Financial incentives are important for the adoption of energy efficient technologies and overcoming certain market barriers to improved energy efficiency. Such incentives are broadly used in various environmental and energy fields and are usually associated with specific technology support, rather than a general sustainable behavioural change. While the declared goal of financial support schemes is to save energy or reduce harmful emissions rather than to foster new technologies per se, it is very often encountered that such financial support for energy efficient technologies does not ensure real energy savings due to the rebound effect and remaining barriers. It is common for financial support to be given to power producers for the verified production of renewable electricity, in the form of a guaranteed financial incentive (feed-in tariff). In the energy efficiency policy research little attention has been paid to the possible use of a feed-in tariff, in the form of a fixed financial incentive based on the kWh saved by the end-user. This paper discusses the possible setup of a feed-in tariff for energy savings. The paper first explores the rationale behind and the possible functionality of a feed-in for energy savings, giving examples of similar policy tools implemented or planned. The paper looks into additionality and persistency of energy savings and explores core interactions between the feed-in and existing tools for energy efficiency. Finally, key advantages and complexities related to a feed-in tariff scheme for energy savings are discussed, intending to open a discussion and foster further research on the topic.

  7. Feed-in tariffs versus quotas: how to promote renewable s and stimulate technical progress for cost decrease?

    Energy Technology Data Exchange (ETDEWEB)

    Menanteau, Ph.; Finon, D.; Lamy, M.L

    2002-07-01

    Incentive schemes for the development of renewable energy sources may focus on quantities (defining national targets and setting up bidding systems, or quota systems providing for green certificate trading), or they may focus on prices (feed-in tariffs). Whatever the system chosen, the role of the public authorities is quite specific: to stimulate technical progress and speed up the technological learning processes so that ultimately renewable energy technologies will be able to compete with conventional technologies, once the environmental costs have been internalized. A comparison of instruments must thus take into account the characteristics of the innovation process and adoption conditions (uncertainties regarding cost curves, learning effects) which means also looking at dynamic efficiency criteria. The paper concludes that a system of feed-in tariffs is more efficient than a bidding system, but highlights the theoretical interest of green certificate trading which must be confirmed through practice, given the influence of market structures and rules on the performance of this type of approach.

    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.

    Africa's vast renewable energy sources have been used with variable success rates. Although the area has potential for hydro, geothermal, biomass, solar and wind energy, these energy sources have not been largely exploited due to a lack of political interest and a lack of investment. Some of these renewable energy sources can meet part of the energy needs of African countries while offering additional advantages, such as decreasing air pollution at the local and regional levels. Development of renewable energy sources requires less capital than conventional energy systems. Renewable energy also provides clean energy to individuals and enterprises. However, the lack of promotion of renewable energy in Africa can be attributed to problems linked to poverty and to the already low greenhouse gas emissions in Africa. According to decision makers in Africa, arguments that favour the use of renewable energy for the purpose of environmental protection must be based on solid empirical facts regarding increasing oil prices; advantages of renewable energy; or, the reduction of risks associated with shortages of hydroelectricity during periods of drought. Other considerations that favour the use of renewable energy include job creation, energy consumption in the agroalimentary and forestry sectors, indoor air quality, and energy source development in rural areas, particularly for hospitals, schools and mission centres. This article commented on various types of renewable energy sources, such as hydro, solar, wind, biomass, and geothermal energy sources. Also, it explained which renewable energy sources have succeeded in Africa, and which types have less chance of succeeding. The obstacles encountered in the development and use of renewable energy sources in Africa were also discussed with reference to political, financial and human obstacles. The short and long term priorities were also addressed. It was concluded that certain types of renewable energies can reduce risks

    Renewable energies are recognized as the main remedy for global warming and energy insecurity issues. While considerable efforts are being put into increasing the share of renewable energies to decarbonize the global energy supply portfolio, the unintended consequences of increased renewable energy production have been overlooked. Using a system of systems (SoS) approach that considers the water-land-energy-economy nexus, this presentation discusses the trade-offs between the sustainability of water, land, energy and economic resources that must not be overlooked in developing sustainable solutions to global warming. It is shown how considering these trade-offs can make some of the renewable energies less attractive. A portfolio risk balancing approach is proposed to develop regional energy supply mixes that balance the overall effects of the energy mix on various resources while taking into account the regional limitations in resource availability. Such energy mixes would include both renewable and non-renewable energies, but would not solve one problem (i.e. global warming) by worsening other problems (e.g., water scarcity, food shortage, economic instability).

    Full Text Available Electrical energy is versatile and considered as the back bone of our daily life. It is directly or indirectly used in everyone’s daily activities. But for having the availability of the sources, we cannot but depend on the renewable resources. The renewable resources can be replaced through the natural process at a rate which is equal or greater than this rate at which they are used. Actually, renewable energy is generated from natural resources like sunlight, wind, tide, geothermal heat, ocean energy etc. that are renewable. A prediction is that in 2030, energy comes from renewable sources is 28% of total generation. Though Bangladesh having lots of natural resources, but still now facing and struggling with the shortage of power, while our neighboring countries are utilizing their sources properly and being richer with better economic growth. The vision for increasing economic growth to 10% by 2017 can be come into reality through the proper utilization of renewable energy resources for having a sustainable development of our country. This paper shows an analytical study on recent energy scenario of Bangladesh and describes the potentiality of available renewable energy resources that should be incorporated in the national energy planning.

    Considering the constantly growing use of technology, modern society requires increasing amounts of electrical power. Acknowledging the global efforts to increase the use of renewable energy sources, the Independent Schools Foundation Academy, a school in Hong Kong, plans to provide the opportunity for students to explore the applications of various forms of renewable energy through a Renewable Energy Education Centre (REEC). Two students are involved in the designing and construction of the Renewable Energy Education Centre to understand the technologies, processes, and provide insight from the students' perspective. The REEC will incorporate various uses of renewable energy, including a solar photovoltaic system, hybrid photovoltaic/thermal system, vertical windmill, hot water heater, and heat pump. As a means to enrich students' learning experiences, the REEC will be open to access by science students for a wide range of investigations, such as science experiments related to renewable energy and energy efficiency, providing opportunities for student led research projects, Personal Projects and IB Extended Essays. In short, the Independent Schools Foundation Academy aims to allow students to familiarize themselves with various forms of renewable energy from a young age, and develop a deeper understanding of technologies that will become primary sources of electrical power in the near future.

  12. 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.

    CO{sub 2} emissions reduction, renewable energy deployment and energy efficiency are three main energy/environmental goals, particularly in Europe. Their relevance has led to the implementation of support schemes in these realms. Their coexistence may lead to overlaps, synergies and conflicts between them. The aim of this paper is to analyse the interactions between energy efficiency measures and renewable energy promotion, whereas previous analyses have focused on the interactions between emissions trading schemes (ETS) and energy efficiency measures and ETS and renewable energy promotion schemes. Furthermore, the analysis in this paper transcends the 'certificate' debate (i.e., tradable green and white certificates) and considers other instruments, particularly feed-in tariffs for renewable electricity. The goal is to identify positive and negative interactions between energy efficiency and renewable electricity promotion and to assess whether the choice of specific instruments and design elements within those instruments affects the results of the interactions.

    Full Text Available Abstract - With the continuously rising energy demand and much dependence on imported fossil fuels, the Philippines is developing more sustainable sources of energy. Renewable energy seems to be a better alternative solution to meet the country’s energy supply and security concerns. Despite its huge potential, investment in renewable energy sources is challenged with competitive prices of fossil fuels, high start-up cost and lower feed-in tariff rates for renewables. To address these problems, this study aims to analyze energy investment scenarios in the Philippines using real options approach. This compares the attractiveness of investing in renewable energy over continuing to use coal for electricity generation under uncertainties in coal prices, investments cost, electricity prices, growth of investment in renewables, and imposing carbon tax for using fossil fuels.

    Full Text Available The Turkish Grand National Parliament passed a renewable energy promotion law that provides feed-in tariffs for electricity generation from renewable energy sources in 2005. This law was not attractive to investors due to the low level of feed-in tariffs. Then, in 2011, the promotion law was amended and a new support scheme integrated in the day-ahead market was introduced. Therefore, the main purpose of this article is to explain the new support mechanism, analyze it from the financial perspective, and discuss the related key issues and challenges. In addition, to further improve the support mechanism, some recommendations have been made to policymakers.

  17. An optimal renewable energy mix for Indonesia

    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

    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.

    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...

    Richardson, K. [Community Renewable Energy, Newcastle upon Tyne (United Kingdom)

    2008-07-01

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

  5. Financing renewable energy for Village Power application

    Energy Technology Data Exchange (ETDEWEB)

    Santibanez-Yeneza, G.

    1997-12-01

    When one talks of rural development, no doubt, the issue of rural energy is not far behind. As a significant component of any development strategy, rural energy is seen as the engine for growth that can bring about economic upliftment in the countryside. Many approaches to rural energy development have been tried. These approaches differ from country to country. But regardless of structure and approach, the goal remain essentially the same: to provide rural communities access to reliable energy services at affordable prices. In recent years, as global concern for the environment has increased, many governments have turned to renewable energy as a more environment friendly alternative to rural electrification. Technological advances in renewable energy application has helped to encourage this use. System reliability has improved, development costs have, to some extent been brought down and varied application approaches have been tried and tested in many areas. Indeed, there is huge potential for the development of renewable energy in the rural areas of most developing countries. At the rural level, renewable energy resources are almost always abundantly available: woodwaste, agricultural residues, animal waste, small-scale hydro, wind, solar and even sometimes geothermal resources. Since smaller scale systems are usually expected in these areas, renewable energy technologies can very well serve as decentralized energy systems for rural application. And not only for rural applications, new expansion planning paradigms have likewise led to the emergence of decentralized energy systems not only as supply options but also as corrective measures for maintaining end of line voltage levels. On the other hand, where renewable energy resource can provide significant blocks of power, they can be relied upon to provide indigenous power to the grids.

    The Renewable Energy Atlas (Atlas) of the United States is a compilation of geospatial data focused on renewable energy resources, federal land ownership, and base map reference information. It is designed for the U.S. Department of Agriculture Forest Service (USFS) and other federal land management agencies to evaluate existing and proposed renewable energy projects. Much of the content of the Atlas was compiled at Argonne National Laboratory (Argonne) to support recent and current energy-related Environmental Impact Statements and studies, including the following projects: (1) West-wide Energy Corridor Programmatic Environmental Impact Statement (PEIS) (BLM 2008); (2) Draft PEIS for Solar Energy Development in Six Southwestern States (DOE/BLM 2010); (3) Supplement to the Draft PEIS for Solar Energy Development in Six Southwestern States (DOE/BLM 2011); (4) Upper Great Plains Wind Energy PEIS (WAPA/USFWS 2012, in progress); and (5) Energy Transport Corridors: The Potential Role of Federal Lands in States Identified by the Energy Policy Act of 2005, Section 368(b) (in progress). This report explains how to add the Atlas to your computer and install the associated software; describes each of the components of the Atlas; lists the Geographic Information System (GIS) database content and sources; and provides a brief introduction to the major renewable energy technologies.

  9. The Park of Renewable Energy geoethical project

    Directory of Open Access Journals (Sweden)

    Patrizia Sibi

    2012-07-01

    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.

    Milčiuvienė Saulė

    2014-06-01

    Full Text Available The article analyzes the investment environment in renewable electricity generation capacities, evaluating the credibility of long term renewable energy targets, the stability of promotion schemes and the impartiality of national administrative procedure. The article explores two main questions: (i are the EU and Lithuanian energy policy targets and promotion schemes credible enough to convince private investors to put their money in renewable energy development; (ii does national administrative procedure put a disproportional burden on renewable energy investors or on certain group of investors? The assessment of the investment environment includes a large number of criteria, but we analyze three of them: the stability of long term strategy; the attractiveness of promotionmeasures; and the simplicity and transparency of administrative procedure. Two further criteria are investigated: the stability of targets in renewable energy and the stability of promotional measures. The greatest uncertainty for investors occurs because of constantly changing support schemes of renewable energy sources-schemes that are not harmonized among the member States. At the national level the main driver in the development of small generators is the feed-in tariff. However, the high feed-in tariff does not always guarantee the smooth development of small scale generators of renewable energy.

    Time Warner Cable (TWC), now Charter Communications (CC), partnered with the National Renewable Energy Laboratory (NREL) to assess the technical and economic potential for solar photovoltaic (PV), wind, and ground-source heat-pump systems at 696 TWC facilities. NREL identified 306 sites where adding a renewable energy system would provide cost savings over the project life-cycle. In general, the top sites have some combination of high electricity rates ($0.16-$0.29/kWh), significant state incentives, and favorable net-metering policies. If all projects were implemented via third-party power purchase agreements, TWC/CC would save $37 million over 25 years and meet 10.5% of their energy consumption with renewable energy. This paper describes the portfolio screening methodology used to identify and prioritize renewable energy opportunities across the TWC sites, as well as a summary of the potential cost savings that may be realized by implementing these projects. This may provide a template for other companies interested in identifying and prioritizing renewable energy opportunities across a large number of geographically dispersed sites. Following this initial portfolio analysis, NREL will be conducting in-depth analysis of project development opportunities at ten sites and evaluating off-grid solutions that may enable carbon emission reduction and grid independence at select facilities.

    The expansion of renewable energies figures at the centre of the energy policy debate in Germany. On the one hand this has been a success story over the past years, as is reflected by corresponding increases in electricity production and a marked increase in the capacity of renewable energy production. On the hand the development of the reallocation charge under the Renewable Energy Law (EEG), along with other challenges associated with the energy turnaround such as the expansion of the networks, have evoked fundamental criticism against the EEG. This provokes the question as to whether feed-in rates or quotas are the better means of achieving the set expansion goals for renewable energies. A fundamental analysis of the systems used within the EU for managing renewable energies shows that the majority of member states rely on feed-in models and that they fare better in terms of achieving their goals than do countries with quota models. For Germany's future it would therefore appear advisable to expand the existing EEG system by addressing the demand side and to give it a significantly more efficient design.

  19. Renewable energy and climate policies: Studies in the forest and energy sector

    Energy Technology Data Exchange (ETDEWEB)

    Kangas, H.-L.

    2012-07-01

    This dissertation examines the impacts of energy and climate policies on the energy and forest sectors, focusing on the case of Finland. The thesis consists of an introduction article and four separate studies. The dissertation was motivated by the climate concern and the increasing demand for renewable energy. In particular, the renewable energy consumption and greenhouse gas emission reduction targets of the European Union were driving this work. In Finland, both forest and energy sectors are in key roles in achieving these targets. In fact, the separation between forest and energy sector is diminishing as the energy sector is utilizing increasing amounts of wood in energy production and as the forest sector is becoming more and more important energy producer. The objective of this dissertation is to find out and measure the impacts of climate and energy policies on the forest and energy sectors. In climate policy, the focus is on emissions trading, and in energy policy the dissertation focuses on the promotion of renewable forestbased energy use. The dissertation relies on empirical numerical models that are based on microeconomic theory. Numerical partial equilibrium mixed complementarity problem models were constructed to study the markets under scrutiny. The separate studies focus on co-firing of wood biomass and fossil fuels, liquid biofuel production in the pulp and paper industry, and the impacts of climate policy on the pulp and paper sector. The dissertation shows that the policies promoting wood-based energy may have unexpected negative impacts. When feed-in tariff is imposed together with emissions trading, in some plants the production of renewable electricity might decrease as the emissions price increases. The dissertation also shows that in liquid biofuel production, investment subsidy may cause high direct policy costs and other negative impacts when compared to other policy instruments. The results of the dissertation also indicate that from the

    2012-12-01

    Full Text Available A broad scientific consensus exists that the global climate is changing. The Earth’s surface temperature could rise significantly over the next few decades, leading to us witnessing an entirely new and unknown planet. Improved energy efficiency, decreasing use of fossil fuels and wide diffusion of various renewable energy sources are among the focal measures to limit global warming to a sustainable level. The objective of this study is to analyse how renewable energy, such as wind power and bioenergy, could be efficiently commercialized. The evaluation is based on a case study and expert analyses exploiting lateral and parallel thinking methods, and group decision support systems tools. The results reveal that some of the generated ideas are ready for implementation to commercialize renewable energy, whereas others still require technical and commercial development and improvements before maturity.

  13. Essays in renewable energy and emissions trading

    Science.gov (United States)

    Kneifel, Joshua D.

    Environmental issues have become a key political issue over the past forty years and has resulted in the enactment of many different environmental policies. The three essays in this dissertation add to the literature of renewable energy policies and sulfur dioxide emissions trading. The first essay ascertains which state policies are accelerating deployment of non-hydropower renewable electricity generation capacity into a states electric power industry. As would be expected, policies that lead to significant increases in actual renewable capacity in that state either set a Renewables Portfolio Standard with a certain level of required renewable capacity or use Clean Energy Funds to directly fund utility-scale renewable capacity construction. A surprising result is that Required Green Power Options, a policy that merely requires all utilities in a state to offer the option for consumers to purchase renewable energy at a premium rate, has a sizable impact on non-hydro renewable capacity in that state. The second essay studies the theoretical impacts fuel contract constraints have on an electricity generating unit's compliance costs of meeting the emissions compliance restrictions set by Phase I of the Title IV SO2 Emissions Trading Program. Fuel contract constraints restrict a utility's degrees of freedom in coal purchasing options, which can lead to the use of a more expensive compliance option and higher compliance costs. The third essay analytically and empirically shows how fuel contract constraints impact the emissions allowance market and total electric power industry compliance costs. This paper uses generating unit-level simulations to replicate results from previous studies and show that fuel contracts appear to explain a large portion (65%) of the previously unexplained compliance cost simulations. Also, my study considers a more appropriate plant-level decisions for compliance choices by analytically analyzing the plant level decision-making process to

    Full Text Available The energy sector reform in the Republic of Croatia (started 2001, which comprises restructuring, liberalization, privatization, and changes in the overall energy sector, has a significant effect on the possibilities of introducing and increasing the share of renewable energy sources (RES. The adoption of a new legislative framework within the context of reforming Croatia’s energy sector is of key importance for further development and for the future or RES utilization. The Electricity Market Act sets out the le- gal obligation to purchase electricity produced from RES in the manner that a quota or a minimum obligatory share of RES in electricity production is determined by a Government ordinance combined with Tariff system for the production of electricity from renewable energy sources and co-generation. Consequently, on the one hand, incentive funds needed to cover increased costs of production from RES will be collected from customers through the supplier and distributed to privileged producers (feed-in-tariffs, purchase is guaranteed to RES producers on known terms through the Market Opera- tor. On the other hand, RES investment projects will be encouraged by pur- pose-specific government subsidy and by the Environmental Protection and Energy Efficiency Fund (out of public budget. By applying new energy legislation and associated by-laws (coming into force in 2007, RES projects in Croatia will be provided with a complete and stable legal framework as well as support through incentive measures which will equitably value environmental, social and other benefits of RES use.

    The City of Hermosa Beach, California, with the support of the AGU's TEX program, is exploring the potential for renewable energy generation inside the City, as part of the implementation of the City's 2015 Municipal Carbon Neutral Plan. Task 1: Estimate the technical potential of existing and future technologies Given the City's characteristics, this task will identify feasible technologies: wind, solar, tidal/wave, wastewater biogas, landfill biogas, microscale anaerobic digestion (AD), and complementary energy storage. Some options may be open to the City acting alone, but others will require working with municipal partners and private entities that provide services to Hermosa Beach (e.g., wastewater treatment). Energy storage is a means to integrate intermittent renewable energy output. Task 2: Review transaction types and pathways In this task, feasible technologies will be further examined in terms of municipal ordinances and contractual paths: (a) power purchase agreements (PPAs) with developers, under which the City would purchase energy or storage services directly; (b) leases with developers, under which the City would rent sites (e.g., municipal rooftops) to developers; (c) ordinances related to permitting, under which the City would reduce regulatory barriers to entry for developers; (d) pilot projects, under which the City would engage with developers to test new technologies such as wind/wave/microscale AD (pursuant to PPAs and/or leases); and (e) existing projects, under which the City would work with current wastewater and landfill contractors to understand (i) current plans to develop renewable energy, and (ii) opportunities for the City to work with such contractors to promote renewable energy. Task 3: Estimate costs by technology Finally, the last task will gather existing information about the costs, both current and projected, of the feasible technologies, including (i) overnight construction cost (capital); (ii) integration costs (e

    Full Text Available ieving the Renewable Energy Target for Jamaica Abstract: The high cost of energy in Jamaica, one of the highest in the Caribbean region, is usually cited as a hindrance to industrial development and efficiency, especially in the manufacturing sector. High energy cost is also considered to be a national energy security issue and the government is taking steps to ensure adequate supply of energy at affordable prices. In the current National Development Plan, the government has set a target for renewable energy sources to supply 20% of the country's energy need by the year 2030. Using a linear programing model of energy planning, we examine how realistically this target could be achieved. Our findings indicate that the 20% renewable energy target is technically achievable with the optimal plan showing a mixture of wind power, hydropower and bagasse power but no solar power. However, when the timeline for investment in new generating capacities that will ensure the attainment of the target is considered, it becomes highly improbable that the target will be met. This study fills the gap that exists in evidence-based analysis of energy policy in Jamaica.

  10. On market integration of renewable energies

    2014-12-05

    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 primary objective of this project was to utilize a flexible, energy-efficient facility, called the DRI Renewable Energy Experimental Facility (REEF) to support various renewable energy research and development (R&D) efforts, along with education and outreach activities. The REEF itself consists of two separate buildings: (1) a 1200-ft2 off-grid capable house and (2) a 600-ft2 workshop/garage to support larger-scale experimental work. Numerous enhancements were made to DRI's existing renewable power generation systems, and several additional components were incorporated to support operation of the REEF House. The power demands of this house are satisfied by integrating and controlling PV arrays, solar thermal systems, wind turbines, an electrolyzer for renewable hydrogen production, a gaseous-fuel internal combustion engine/generator set, and other components. Cooling needs of the REEF House are satisfied by an absorption chiller, driven by solar thermal collectors. The REEF Workshop includes a unique, solar air collector system that is integrated into the roof structure. This system provides space heating inside the Workshop, as well as a hot water supply. The Workshop houses a custom-designed process development unit (PDU) that is used to convert woody biomass into a friable, hydrophobic char that has physical and chemical properties similar to low grade coal. Besides providing sufficient space for operation of this PDU, the REEF Workshop supplies hot water that is used in the biomass treatment process. The DRI-REEF serves as a working laboratory for evaluating and optimizing the performance of renewable energy components within an integrated, residential-like setting. The modular nature of the system allows for exploring alternative configurations and control strategies. This experimental test bed is also highly valuable as an education and outreach tool both in providing an infrastructure for student research projects, and in highlighting renewable

    In the Finnish Energy Strategy, approved by the Finnish Government in 1997, the emphasis is laid on the importance of bioenergy and other renewable energy sources for the creation of such prerequisites for the Finnish energy economy that the supply of energy can be secured, the price on energy is competitive and the emissions from energy generation are within the limits set by the international commitments made by Finland. In 1998, the European Union Meeting of the Ministers of Energy adopted a resolution taking a positive attitude to the Communication from the Commission 'Energy for the future: Renewable sources of energy' - White Paper for a Community Strategy and Action Plan. National measures play a key role in the achievement of the objectives set in the White Paper. This Action Plan for Renewable Energy Sources is a national programme in line with the EU's White Paper. It comprises all renewable sources of energy available in Finland. It encompasses even peat, which in Finland has traditionally been considered to be a solid biofuel but is internationally classified as one of the non-renewable sources of energy. In the Action Plan, objectives are set for the volume of renewable energy sources used in the year 2010 including a prognosis on the development by the year 2025. The goal is that by the year 2010 the volume of energy generated using renewable energy sources has increased by 50% compared with the year 1995. This would mean an increase by 3 Mtoe, which is about 1 Mtoe more than anticipated in the outlook based on the Finnish Energy Strategy. A further goal is to double the use of renewable energy sources by the year 2025. The aggregate use of renewable energy sources depends to a large extent both on the development of the price on energy produced using other energy sources and on possible changes in the production volume of the Finnish forest industry. The most important objective stated in the Action Plan is to improve the

    UNDP has set, as one of its main goals, to help the entire UN system to become a powerful force for sustainable human development - i.e., development that is people-centred, that both generates economic growth and distributes the fruits of growth equitably, and that empowers people to participate in the decisions that shape their lives. Specifically, UNDP has - determined that it will focus on four key aspects of sustainable human development - eradicating poverty, providing people with income-earning opportunities, increasing women`s role in development, and protecting and regenerating the environment. Energy can either serve as a barrier to achieving these objectives or it can become an instrument for attaining them. As countries develop, their needs for energy services expand and develop. How those needs are met has significant implications for the environment and the continued capacity of countries to grow. If current patterns of energy production, distribution, and consumption continue and spread to other countries, development and growth in at least some of those countries could slow dramatically. What is needed are new, more efficient systems for producing, distributing, and consuming energy as well as increased reliance on environmentally sound energy systems that contribute to economic growth and expand people`s opportunities.

    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.

    Directory of Open Access Journals (Sweden)

    2017-12-01

    Full Text Available For many decades, it has been stated that renewable energy, RE, needs subsidy, otherwise it will not be able to compete or sustain. For a certain level, this statement was valid. In this period, the investment costs for both wind and photovoltaic, PV, were high. In other words, production costs of both of them reached around 7.0 and 13.0 Cent US$ per kWh. On the other hand, oil and natural gas, NG, prices were low; i.e. less than US$ 30.0 per oil barrel and around US$ 4.0 per million British thermal unit, MMBTU, of NG. Also, policies of promoting RE were limited; almost there are two main policies, Feed-in-Tariff, FiT, in limited developed countries and international tenders. As a result, investment in RE was usually led by developed countries and minor share from the developing countries. This was the scene of RE before around 10 years. Nowadays, the scene of RE totally differs. Starting from the policies side, through auctions in both solar and wind energies, new records of prices have been reached. In numbers, in the field of wind energy Morocco and Egypt already signed contracts with prices lower than 4.0 US$ Cents/kWh. For PV, there is a dramatic devaluation in the prices. Now we are speaking for less than 0.7 million US$ per MW for turnkey projects. As a result, during the last couple of years, the global RE market witnessed a bundle of an outstanding prices, El-Sewihan Project at Abu Dhabi, 2.42 US$ Cent/kWh. Mexico and Dubai projects, 3.6 and 3.0 US$ Cent/kWh. Few days ago, Dubai Electricity and Water Authority, DEWA, received $9.45 cents per kilowatt-hour for its 200MW concentrated solar power (CSP plant. All these figures, and others, gave us important messages; 1 Despite low prices of oil and NG, RE is able to compete and offer outstanding prices, 2 Wind and PV technologies do not need any kind of subsidy, rather than they need a real free market to compete, 3 CSP is a low hanging fruit and it will witness a frog-leap during the

    This report summarizes the completion of four renewable energy installations supported by California Energy Commission (CEC) grant number CEC Grant PIR-11-005, the US Department of Energy (DOE) Assistance Agreement, DE-EE0003070, and the Sacramento Municipal Utility District (SMUD) Community Renewable Energy Deployment (CRED) program. The funding from the DOE, combined with funding from the CEC, supported the construction of a solar power system, biogas generation from waste systems, and anaerobic digestion systems at dairy facilities, all for electricity generation and delivery to SMUD’s distribution system. The deployment of CRED projects shows that solar projects and anaerobic digesters can be successfully implemented under favorable economic conditions and business models and through collaborative partnerships. This work helps other communities learn how to assess, overcome barriers, utilize, and benefit from renewable resources for electricity generation in their region. In addition to reducing GHG emissions, the projects also demonstrate that solar projects and anaerobic digesters can be readily implemented through collaborative partnerships. This work helps other communities learn how to assess, overcome barriers, utilize, and benefit from renewable resources for electricity generation in their region.

    In 2008, the US Department of Energy’s (DOE) Wind and Water Power Program issued a funding opportunity announcement to establish university-led National Marine Renewable Energy Centers. Oregon State University and the University of Washington combined their capabilities in wave and tidal energy to establish the Northwest National Marine Renewable Energy Center, or NNMREC. NNMREC’s scope included research and testing in the following topic areas: • Advanced Wave Forecasting Technologies; • Device and Array Optimization; • Integrated and Standardized Test Facility Development; • Investigate the Compatibility of Marine Energy Technologies with Environment, Fisheries and other Marine Resources; • Increased Reliability and Survivability of Marine Energy Systems; • Collaboration/Optimization with Marine Renewable and Other Renewable Energy Resources. To support the last topic, the National Renewable Energy Laboratory (NREL) was brought onto the team, particularly to assist with testing protocols, grid integration, and testing instrumentation. NNMREC’s mission is to facilitate the development of marine energy technology, to inform regulatory and policy decisions, and to close key gaps in scientific understanding with a focus on workforce development. In this, NNMREC achieves DOE’s goals and objectives and remains aligned with the research and educational mission of universities. In 2012, DOE provided NNMREC an opportunity to propose an additional effort to begin work on a utility scale, grid connected wave energy test facility. That project, initially referred to as the Pacific Marine Energy Center, is now referred to as the Pacific Marine Energy Center South Energy Test Site (PMEC-SETS) and involves work directly toward establishing the facility, which will be in Newport Oregon, as well as supporting instrumentation for wave energy converter testing. This report contains a breakdown per subtask of the funded project. Under each subtask, the following

    2013-07-15

    Thailand’s support policies for renewable energy (RE) in the power sector have allowed individual small projects to add up to something substantial, attracting more investment and leading to faster growth in the sector than in most other Asian nations. Thai energy policy is complex, and the development of RE has not been without controversy. While this paper provides some elements of the context, it cannot cover all aspects of Thai energy policy. Instead it focuses on identifying factors that can explain the relative success of Thai policies and highlights some lessons for future development. Key messages include: Thailand was among the first countries in Asia to introduce incentive policies for the generation of electricity from renewable energy (RE) sources, leading to rapid growth, particularly in solar power; programmes for small and very small power producers created predictable conditions for RE investors to sell electricity to the grid. The 'Adder', a feed-in premium, guarantees higher rates for RE, making the investments profitable. Thailand also regularly updates technical regulations, provides preferential financing, and invests in research and training; civil society involvement strengthened and improved RE policies. In Thailand, outside expertise and links to international networks brought in by civil society experts were crucial for the design and approval of the incentive measures; and, the Thai Government is now adapting its policies to take account of recent technological progress and market growth. It is considering a sophisticated feed-in tariff to better control costs, while continuing to offer an enabling environment for RE investments.

In this paper I have tried to highlight the profitability and economic efficiency of growing of this plant. Production capacity exceeding 2 tonnes dry matter/1000mp. The yield depends on climatic conditions, adequate soil moisture, soil nutrients, and range from 1 to 3 t/1000mp, dry. Cardoon seed contains on average 24% oil (category: 19-32%, with the same qualities as the sunflower. Quantity of seed production to 480 kgs/1000mp, while ordinary productivities range 70 to 330 kg/1000mp, always depending on the total biomass production. Growing cardooncan replace traditional crops, partly by ensuring a good profit for the farmer (double the wheat and rapeseed and bio fuel production with high energy content. Solid bio fuels (pellets, briquettes, artichokes, etc. can reach the enduser, at prices up to 30-40% lower than the price of oil. Because cardoon is a perennial plant which grows once every 10-12 years, and preparing the ground and sowing it will be carried out at intervals so large (this plant is harvested annually,it is remarkable cost reduction efficiency of growing this plant.In addition to the obvious environmental advantages by producing green energy, growing artichokes garden preserves the soil covered for the most part of the year, thereby minimizing the risk of soil erosion and limit the pollution of soil and groundwater with agrochemical products, especially in areas with intensive agriculture, because it does not require additional fertilization and/or with the use of chemical fertilizers or pesticides.

    I study several policy instruments for carbon mitigation with a focus on subsidies for renewable energies, emission taxes and emission allowances. In Chapter 1, I analyze the optimal design and the welfare implications of two policies consisting of an emission tax for conventional fossil-fuel utilities combined with a subsidy for the producers of renewable energy equipment and an emission tax combined with a feed-in tariff for renewable electricity. In Chapter 2 I study the empirical interrelationships between European emission allowance prices and prices for electricity, hard coal and natural gas with an application to portfolio allocation. In Chapters 3 and 4, I discuss several policy-related issues of emissions trading, in particular the potential for market manipulations by firms holding a dominant position in the emission market, the output market or both, and competitive distortions and leakage due to unequal emission regulations across industries, sectors, regions, or countries.

  16. Energy in buildings: Efficiency, renewables and storage

    Science.gov (United States)

    Koebel, Matthias M.

    2017-07-01

    This lecture summary provides a short but comprehensive overview on the "energy and buildings" topic. Buildings account for roughly 40% of the global energy demands. Thus, an increased adoption of existing and upcoming materials and solutions for the building sector represents an enormous potential to reduce building related energy demands and greenhouse gas emissions. The central question is how the building envelope (insulation, fenestration, construction style, solar control) affects building energy demands. Compared to conventional insulation materials, superinsulation materials such as vacuum insulation panels and silica aerogel achieve the same thermal performance with significantly thinner insulation layers. With low-emissivity coatings and appropriate filler gasses, double and triple glazing reduce thermal losses by up to an order of magnitude compared to old single pane windows, while vacuum insulation and aerogel filled glazing could reduce these even further. Electrochromic and other switchable glazing solutions maximize solar gains during wintertime and minimize illumination demands whilst avoiding overheating in summer. Upon integration of renewable energy systems into the building energy supply, buildings can become both producers and consumers of energy. Combined with dynamic user behavior, temporal variations in the production of renewable energy require appropriate storage solutions, both thermal and electrical, and the integration of buildings into smart grids and energy district networks. The combination of these measures allows a reduction of the existing building stock by roughly a factor of three —a promising, but cost intensive way, to prepare our buildings for the energy turnaround.

    It is the intention of the Yakama Nation to make improvements on the Wapato Irrigation Project (WIP) for the benefit of all stakeholders. Water management, water conservation and water allocation on the Wapato Irrigation Project is equally as important as hydropower. Irrigation will always be the primary purpose of this water system, but the irrigation system can also generate energy. The purpose of this project is the purchase and installation of inflow water turbines to generate an additional one megawatt of hydro-electrical power. The project will occur in two phases, Environmental Assessment and Project Implementation. The core objective for this proposal is to meet the Yakama Nation’s goal in hydroelectric power development. This will include the installation of inflow water turbines on the Wapato Irrigation Project. The Yakama Nation will prepare an Environmental Assessment in preparation to purchase and install new water turbines for hydropower generation of 1 Megawatt. This is a valuable economic development strategy for Yakama Nation that will create new jobs, improve and increase rural electrification, and attract private investments. This water system has an untapped low head/low power potential without the need to construct a new dam. The objective of Phase 1 is to complete an environmental assessment and obtain approval to proceed with installation of the hydroelectric power system.

  9. International entrepreneurship within offshore renewable energy

    Energy Technology Data Exchange (ETDEWEB)

    Loevdal, Nicolai S.

    2011-07-01

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

    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.

    Full Text Available Energy is one of the basic needs of humanity and, for ages, the sun seemed to be the main source ofall energy in the universe and that is why the ancient Egyptians used to venerate it. Many wastes andcorpses – under pressure and heat – have been converted throughout the years inside the earth intothe oil on which recent development is totally based to support humans’ life, particularly intransportation and power generation. As time passes, it has been proven that oil will vanish. For thefirst moment, it seemed like mankind will certainly suffer due to such a hard situation and some peoplethought that we will get back to stone ages when oil no longer exists. Thanks for the Renewable Energy scientist who has looked at the issue from a different prospective,that is, even if oil vanishes, the main reason of its existence is still there, that is the sun . The sun has the capability to still make people enjoy their life not only by enjoying the sunny weatherin many places of the world and having good times on the beach for those who live by the sea but alsothe sun can still provide man with required energy and cause the wind to blow, the waves to raise, theplants to be converted to biomass, and the earth to store its geothermal energy. As long as life goes on, the sun will always rise and will always grant its energy to mankind. It is theclean, renewable and sustainable energy, which guarantees sustainable development. Because of the high correlation between renewable energy and sustainable development, the editorialteam of this journal thought of offering a hub to researchers interested in these two important fields topresent their work and share it with others who have the same interest in such a wide area ofresearch .

  15. The impacts of non-renewable and renewable energy on CO2emissions in Turkey.

    Science.gov (United States)

    Bulut, Umit

    2017-06-01

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

  16. Essays on the economics of decarbonization and renewable energy support

    Energy Technology Data Exchange (ETDEWEB)

    Jaegemann, Cosima Claudia

    2014-06-05

    The thesis consists of five essays investigating various aspects associated with the decarbonization of Europe's power sector and the politically incentivized expansion of renewable energy generation. The first essay analyzes the economic implications of alternative decarbonization pathways and policy instruments for Europe's power sector up to 2050 and illustrates the importance of ensuring competition between all low-carbon technologies in order to limit the costs of decarbonization. The second essay analyzes the economic inefficiency associated with the concept of grid parity for the case of photovoltaic (PV). In order to both enhance overall welfare and avoid redistributional effects, the indirect financial incentive for in-house PV electricity consumption should be abolished. The third essay discusses the system price effect of wind and solar power generation and illustrates that the decrease in the marginal value of wind and solar power (as a consequence of increased penetration) is already highly relevant for both wind and solar power generation in Germany. The fourth essay adds to the ongoing debate surrounding the cost-efficient achievement of politically implemented renewable energy targets. Renewable energy support schemes that fail to incentivize investors to account for differences in the marginal value of wind and solar power generation are associated with excess costs as they prevent the equalization of net marginal costs across technologies and regions. The fifth essay analyzes the economic value of storage as a function of the overall generation mix and illustrates the economic inefficiency arising from feed-in tariff systems for the special case of thermal energy storage units in concentrating solar power plants.

  19. Optimal Renewable Energy Systems for Regions

    Directory of Open Access Journals (Sweden)

    Karl-Heinz Kettl

    2014-03-01

    Full Text Available Most sources for renewable energy can be deduced from solar radiation as the main natural income of society. Contrary to conventional fossil and radioactive energy resources that are mined or pumped out from central point sources, solar energy is a de-central resource that requires area for its conversion to useful products and services. This requires a new technological as well as logistical concept for energy systems where regions play a key role as providers of energy and goods. The contribution will provide the conceptual framework for renewable energy system generation on a regional level, taking into account the responsibility of regions to provide goods and services to the larger society and to support urban centres. It will show how optimal resource-technology-demand networks may be constructed, using process network synthesis approaches and how the ecological efficiency of such regional systems can be measured. Application of these methods to real life case studies (in particular the region of Muehlviertel in Austria will on the one hand prove the versatility of the methods presented and on the other hand will provide insight into the scope of necessary change if society moves towards a low carbon sustainable energy system.

  3. PECULIARITIES OF THE RENEWABLE ENERGY BUSINESS MODELS

    Directory of Open Access Journals (Sweden)

    BĂLOI Ionut-Cosmin

    2014-07-01

    Full Text Available By exploring the competitiveness of industries and companies, we could identify the factors whose importance is likely to generate competitive advantage. An inventory of content elements of the business model summarizes the clearest opportunities and prospects. The objectives developed throughout the paper want to identify the pillars of a renewable business model and to describe the strategic dimensions of their capitalisation in regional and national energy entrepreneurship. The trend of increasing the renewable energy business volume is driven by the entrepreneurs and company’s availability to try new markets, with many unpredictable implications and the willingness of these players or their creditors to spend their savings, in various forms, for the concerned projects. There is no alternative to intensive investment strategies, given that the small projects are not able to create high value and competitiveness for interested entrepreneurs. For this reason, the international practice shows that the business models in energy production are supported by partnerships and networks of entrepreneurs who are involved in the development of large projects. The most important feature of renewable business initiatives is on attracting the latest clean emerging technologies, and obviously the investors who can assume the risk of such great projects. The benefits of a well developed business model recommend a prudent approach in the launching in the investment strategies, because the competitive contexts hide always some dissatisfaction of the partners that endanger the business concept’s success. The small firms can develop a profitable business model by exploring the opportunity of the alliances, namely the particular joint ventures (association between Romanian and foreign firms. The advantages of joint venture's partners are considerable; they include access to expertise, resources and other assets that the partners could not achieve on their own

    Walker, A.

    2008-05-01

    This paper describes a method for determining the combination of renewable energy technologies that minimize life-cycle cost at a facility, often with a specified goal regarding percent of energy use from renewable sources. Technologies include: photovoltaics (PV); wind; solar thermal heat and electric; solar ventilation air preheating; solar water heating; biomass heat and electric (combustion, gasification, pyrolysis, anaerobic digestion); and daylighting. The method rests upon the National Renewable Energy Laboratory's (NREL's) capabilities in characterization of technology cost and performance, geographic information systems (GIS) resource assessment, and life-cycle cost analysis. The paper discusses how to account for the way candidate technologies interact with each other, and the solver routine used to determine the combination that minimizes life-cycle cost. Results include optimal sizes of each technology, initial cost, operating cost, and life-cycle cost, including incentives from utilities or governments. Results inform early planning to identify and prioritize projects at a site for subsequent engineering and economic feasibility study.

    As a result of the globalization of knowledge, shortening of the innovation cycle and the aggravation of the price situation, the diffusion of innovation has accelerated. The protection of innovation has become even more important for companies in technologyintensive industries. Legal and actual patent right strategies complement one another, in order to amortize the investment in product development. Climate change is one of today’s truly global challenges, affecting all aspects of socio-economic development in every region of the world. Technology development and its rapid diffusion are considered crucial for tackling the climate change challenge. At the global level, the last decades have seen a continuous expansion of inventive activity in renewable energy technologies. The growth in Renewable Energy (RE) inventions has been much faster than in other technologies, and RE today represents nearly 6% of global invention activity, up from 1.5% in 1990. This paper discusses about global innovation activity in the last five years in the renewable energy sector and describes the Innovation and Technology Management process for supporting managerial decision making.

    2015-01-01

    An energy economy based on renewable energy requires massive energy storage, approx. half of the annual energy consumption. Therefore, the production of a synthetic energy carrier, e.g. hydrogen, is necessary. The hydrogen cycle, i.e. production of hydrogen from water by renewable energy, storage and use of hydrogen in fuel cells, combustion engines or turbines is a closed cycle. Electrolysis splits water into hydrogen and oxygen and represents a mature technology in the power range up to 100 kW. However, the major technological challenge is to build electrolyzers in the power range of several MW producing high purity hydrogen with a high efficiency. After the production of hydrogen, large scale and safe hydrogen storage is required. Hydrogen is stored either as a molecule or as an atom in the case of hydrides. The maximum volumetric hydrogen density of a molecular hydrogen storage is limited to the density of liquid hydrogen. In a complex hydride the hydrogen density is limited to 20 mass% and 150 kg/m(3) which corresponds to twice the density of liquid hydrogen. Current research focuses on the investigation of new storage materials based on combinations of complex hydrides with amides and the understanding of the hydrogen sorption mechanism in order to better control the reaction for the hydrogen storage applications.

    1984-01-01

    For about 25 years, Basic Resources Corp. in New York has been growing on the strength of operations ranging from oil and gas exploration and printing to computer leasing and the manufacture of highway toll-collecting equipment. But since early 1982, when it received an Energy Department grant, a new subsidiary has been working on a project with scant resemblance to any other of the multimillion-dollar firm's operations: the preliminary research for an ocean thermal energy plant that would convert heat on the ocean's surface to power at a site in the Hawaiian islands. Renewable energy -- once largely the domain of dreamers and urban dropouts -- has moved into the corporate mainstream, and more and more companies in the United States and abroad are trying to stake a claim to a piece of its future. Basic Resources is not the only renewable energy source firm doing well. Several hundred exhibitors and other participants -- including a number of foreign visitors -- turned out for the 3-day event. Arco, which has been working on photovoltaics since the late 1970s, is considered the world's largest manufacturer of photovoltaics -- solar cells that convert the sun's energy directly into electricity. But, despite tax credits, worldwide sales and dramatic strides in reducing the cost of the technology, the operation still isn't profitable after the costs of research and other costreduction efforts are included. Nonetheless, Arco has no plans to abandon the field, and its attitude explains why so many firms are bucking the odds and pursuing renewable energy.

    2004-04-01

    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.

    2014-01-01

    NASA's Johnson Space Center has implemented a great number of renewable energy systems. Renewable energy systems are necessary to research and implement if we humans are expected to continue to grow and thrive on this planet. These systems generate energy using renewable sources - water, wind, sun - things that we will not run out of. Johnson Space Center is helping to pave the way by installing and studying various renewable energy systems. The objective of this report will be to examine the completed renewable energy projects at NASA's Johnson Space Center for a time span of ten years, beginning in 2003 and ending in early 2014. This report will analyze the success of each project based on actual vs. projected savings and actual vs. projected efficiency. Additionally, both positive and negative experiences are documented so that lessons may be learned from past experiences. NASA is incorporating renewable energy wherever it can, including into buildings. According to the 2012 JSC Annual Sustainability Report, there are 321,660 square feet of green building space on JSC's campus. The two projects discussed here are major contributors to that statistic. These buildings were designed to meet various Leadership in Energy and Environmental Design (LEED) Certification criteria. LEED Certified buildings use 30 to 50 percent less energy and water compared to non-LEED buildings. The objectives of this project were to examine data from the renewable energy systems in two of the green buildings onsite - Building 12 and Building 20. In Building 12, data was examined from the solar photovoltaic arrays. In Building 20, data was examined from the solar water heater system. By examining the data from the two buildings, it could be determined if the renewable energy systems are operating efficiently. Objectives In Building 12, the data from the solar photovoltaic arrays shows that the system is continuously collecting energy from the sun, as shown by the graph below. Building 12

    This analysis provides first-ever assessment of the extent to which renewable energy is crossing state borders to be used to meet renewable portfolio standard (RPS) requirements. Two primary methods for data collection are Renewable Energy Certificate (REC) tracking and power flow estimates. Data from regional REC tracking systems, state agencies, and utility compliance reports help understand how cross-state transactions have been used to meet RPS compliance. Data on regional renewable energy flow use generator-specific information primarily sourced from EIA, SNL Energy, and FERC Form 1 filings. The renewable energy examined through this method may or may not have actually been used to meet RPS compliance.

    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

    Weilenmann, U.

    2012-06-01

    The operation of observatories at remote sites presents significant demands for electrical energy. The use of renewable energy may become the solution to cope with the ever-rising prices for electrical energy produced from fossil fuels. There is not only a purely commercial aspect, but also the carbon footprint of observatory activities has to be considered. As a first step on the way to a "greener" Paranal Observatory, we propose the installation of a solar cooling system for the cooling of the telescope enclosures, using the abundant insolation that is freely available in the north of Chile. Further into the future, feasible options for photovoltaic and wind energy could supply the needs of the Paranal Observatory in a sustainable manner.

Such an advance would deliver a renewable, environmentally benign energy source for the future. A great technological challenge facing our global future is energy. The generation of energy, the security of its supply, and the environmental consequences of its use are among the world's foremost geopolitical concerns. Fossil fuels - coal, natural gas, and petroleum - supply approximately 90% of the energy consumed today by industrialized nations. An increase in energy supply is vitally needed to bring electric power to the 25% of the world's population that lacks it, to support the industrialization of developing nations, and to sustain economic growth in developed countries. On the geopolitical front, insuring an adequate energy supply is a major security issue for the world, and its importance will grow in proportion to the singular dependence on oil as a primary energy source. Yet, the current approach to energy supply, that of increased fossil fuel exploration coupled with energy conservation, is not scaleable to meet future demands. Rising living standards of a growing world population will cause global energy consumption to increase significantly. Estimates indicate that energy consumption will increase at least two-fold, from our current burn rate of 12.8 TW to 28 - 35 TW by 2050. - U.N. projections indicate that meeting global energy demand in a sustainable fashion by the year 2050 will require a significant fraction of the energy supply to come carbon free sources to stabilize atmospheric carbon dioxide levels at twice the pre-anthropogenic levels. External factors of economy, environment, and security dictate that this global energy need be met by renewable and sustainable

  12. New Solutions for Renewable Energy Trading

    Full Text Available The paper presents one of the key problems in renewable energy trading. The support system for RES is operating on financial levels leaving to the RES producers decisions on the energy trade. However, the flawed legal regulations impose the obligations on Default Electricity Supplier (SzU1 to buy all RES production from the installations located in the areas of the SzU operation. Such legal provisions result in the additional burden on the SzU, which main duty is to provide electric energy to customers who do not want to enter competitive electricity markets. Additionally, over interpretation of the Energy Law provisions by the Energy Regulatory Authority (URE2, allowing the RES producers to trade a part of their production on electricity markets leaving the obligation on SzUs, has led to the speculative trade of renewable energy. Some RES producers sell the electricity produced in competitive markets during peak demand hours – usually working days from 7 a.m. to 8 p.m. – when the Power Exchange prices are significantly higher than the obligatory purchase price. When during off peak demand hours electricity prices in the Power Exchange are lower than the obligatory level, RES producers sell the electric energy to SzUs at the obligatory price, determined by the URE. Such an abuse of fair trade results in the additional income for the RES producers being burden on SzUs, which have to transfer such costs to energy endusers. The simulations, carried out for Poland indicate that the additional costs can count for about 200 mln zł per year.

    Liberalisation of energy markets has been progressing among OECD countries since the early nineties. In Europe this trend was accelerated by the decision in December 1996 by the EU Council of Ministers to adopt a new EU directive on liberalisation of the electricity market. This decision would lead...... to higher efficiency and lower consumer prices. Most EU governments have accepted the new EU directive based on these commercial arguments. Denmark has, however, been in a different situation because its energy policy is based primarily on environmental considerations. Danish energy policy involves...... government promotion of energy conservation and of systems based on renewable energy sources. This type of policy may in some instanes conflict with the principles of the unregulated commercial market. The official Danish target is that 35% of energy demand should be covered by renewables by year 2030...

  20. Review of International Experience with Renewable Energy Obligation Support Mechanisms

    Energy Technology Data Exchange (ETDEWEB)

    Wiser, R.

    2005-06-01

    The main policy instruments currently used in the EU Member States to achieve the targets set for electricity produced from renewable energy sources are: (1) the quota obligation system; (2) the feed-in tariff system; and (3) the tendering system. The current study aims to review the experience gained with the quota obligation system. The report provides an overview of the regions where obligation systems have been implemented and contains a detailed evaluation of the performance of the obligation systems in the USA, the UK and in Sweden. The obligation systems in these countries have been evaluated based on the following criteria: Effectiveness; Market efficiency; Certainty for the renewable energy industry; Cost effectiveness; Stakeholder support for the obligation system; and Equity. The evaluation of international experiences with the obligation system gives rise to a mixed picture. Although an obligation in theory is effective and cost effective, it seems too early to conclude that the system delivers these promises in practice. On the one hand this is due to the limited period of implementation that makes it hard to distinguish between the direct effect of the system and some teething problems that will be solved in due time. On the other hand, the conclusion can be drawn that the obligation is a complex system, which will only function well if designed carefully. It does seem worthwhile, however, to continue monitoring the experiences with the obligation system abroad, because this will further reveal whether the system is indeed effective and cost effective in practice. In the longer term, e.g. beyond 2010, the introduction of an obligation system in the Netherlands could be considered. Finally, as the design of support schemes is being improved, it appears that the basic concepts of both the obligation system and the feed in system have been refined in such a way that the two systems are gradually converging. An important difference between the two systems

    Life cycle analyses of renewable energy sources focus on static accounting of energy and green house gases balances. In this work, we introduce a conceptual framework and a mathematical model to simulate the time evolution of the energy balance of energy conversion technologies. This approach complements static energy return analyses. It is based on a few technical parameters that describe a standard conversion module, a set of deployment objectives, and assumed growth rates for deployment. It is independent of working details of the conversion technology. A set of equations is formulated and solved to model the deployment of the new technology. It allows for evaluation of gross and net produced energy and for estimation of required investments. The model is applied to photovoltaic electricity in Brazil, wind electricity globally and in Brazil, and sugar cane bioethanol. The main conclusions are: (i) photovoltaic electricity, because it requires large energy investments, leads to negative net production of electricity for many years, i.e., for an extended period it is an energy sink and not source; (ii) wind electricity is an attractive option is terms of net electricity production; (iii) sugar cane bioethanol is an attractive option for liquid fuels production for the world.

    When Renewable Energy for Rural Economic Development (RERED) began in 2005, Utah had no commercial wind power projects in operation. Today, the state hosts two commercial wind power plants, the Spanish Fork Wind Project and the Milford Wind Corridor Project, totaling 324 megawatts (MW) of wind capacity. Another project in San Juan County is expected to break ground very soon, and two others, also in San Juan County, are in the approval process. RERED has played a direct role in advancing wind power (and other renewable energy and clean technology innovations) in Utah through its education outreach and research/publication initiatives. RERED has also witnessed and studied some of the persistent barriers facing wind power development in communities across Utah and the West, and its research expanded to examine the diffusion of other energy efficiency and clean technology innovations. RERED leaves a legacy of publications, government reports, and documentary films and educational videos (archived at www.cleantech.usu.edu) to provide important insights for entrepreneurs, policymakers, students, and citizens about the road ahead for transitioning society onto a cleaner, more sustainable future.

    The demand for renewable energy in social energy systems has grown in recent years. In the atmospheric sciences, the energy balances and dynamics in the atmosphere are studied on both local and global scales, and thus estimation of renewable energy is an important practical application. For instance, shortwave solar radiation that reaches Earth's surface is an essential quantity for evaluating the photovoltaic (PV) power generation. Indeed, shortwave solar radiation can be calculated by a radiative transfer solver and an accurate electromagnetic wave scattering theory. A beneficial application of atmospheric sciences is obtaining of solar radiation on the basis of geostationary satellite measurements. Such satellites provide data covering most parts of the Earth every 30 min to 1 h. Geo-parameters such as cloud and aerosol properties are needed for calculating the amount of solar radiation that reaches Earth's surface. Multispectral images acquired by geostationary satellites allow for such geo-parameters to be evaluated. Additionally, polar-orbiting Earth observation satellites are also needed for improving data analysis techniques. For instance, multispectral imagers (e.g., MODIS) and cloud radars (e.g., CloudSat) aboard polar-orbiting satellites can be used to reveal the relationship between multispectral imaging results and the vertical structure of clouds. The EarthCARE (JAXA, ESA, NICT) and the GCOM-C (JAXA) satellites that will be launched in the middle of 2010-era are also used for improving cloud and aerosol process. This paper presents a method using satellite data to evaluate the optical and microphysical parameters of clouds that affect solar radiation. Also presented is a method for evaluating solar radiation that reaches Earth's surface. A new research project in Japan, JST-CREST-EMS (Energy Management System)-TEEDDA (Terrestrial Energy Estimation by Diurnal Data Analyses), which was started in October 2012, is also introduced.

    This paper describes a methodology to quantify the economic and resiliency benefit provided by renewable energy (RE) in a hybrid RE-storage-diesel microgrid. We present a case study to show how this methodology is applied to a multi-use/ multi-function telecommunications facility in southern California. In the case study, we first identify photovoltaic (PV) and battery energy storage system (BESS) technologies that minimize the lifecycle cost of energy at the site under normal, grid-connected operation. We then evaluate how those technologies could be incorporated alongside existing diesel generators in a microgrid to increase resiliency at the site, where resiliency is quantified in terms of the amount of time that the microgrid can sustain the critical load during a grid outage. We find that adding PV and BESS to the existing backup diesel generators with a fixed fuel supply extends the amount of time the site could survive an outage by 1.8 days, from 1.7 days for the existing diesel-only backup system to 3.5 days for the PV/diesel/BESS hybrid system. Furthermore, even after diesel fuel supplies are exhausted, the site can continue to operate critical loads during daytime hours using just the PV/BESS when there is sufficient solar resource. We find that the site can save approximately $100,000 in energy costs over the 25-year lifecycle while doubling the amount of time they can survive an outage. The methodology presented here provides a template for increasing resiliency at telecomm sites by implementing renewable energy solutions, which provide additional benefits of carbon emission reduction and energy cost savings.

    To realize the sustainable development of China’s energy industry, it is necessary to speed up the transformation of energy development mode and deepen the reform of the energy system in an all-round way so as to establish a clean, low-carbon, safe and efficient modern energy system. This paper analysed the opportunities and challenges in energy sectors to promote the energy mix update in China. Fossil energy, especially coal, has brought great progress to the world as well as a great deal of negative effects. In recent years, China’s greenhouse gas emissions continued to grow rapidly, and has become the world’s largest greenhouse gas emitter. To deal with the challenge, the Chinese government has promised that renewable energy will account for 15% of total energy consumption in 2020 and 20% in 2030. This goal requires China to add 800 to 1000 GW of wind, solar and other clean energy.

  13. The Energy Economics of Financial Structuring for Renewable Energy Projects

    Science.gov (United States)

    Rana, Vishwajeet

    2011-12-01

    This dissertation focuses on the various financial structuring options for the renewable energy sector. The projects in this sector are capital-intensive to build but have relatively low operating costs in the long run when compared to traditional energy resources. The large initial capital requirements tend to discourage investors. To encourage renewable investments the government needs to provide financial incentives. Since these projects ultimately generate returns, the government's monetary incentives go to the sponsors and tax equity investors who build and operate such projects and invest capital in them. These incentives are usually in the form of ITCs, PTCs and accelerated depreciation benefits. Also, in some parts of the world, carbon credits are another form of incentive for the sponsors and equity investors to invest in such turnkey projects. The relative importance of these various considerations, however, differs from sponsor to sponsor, investor to investor and from project to project. This study focuses mainly on the US market, the federal tax benefits and incentives provided by the government. This study focuses on the energy economics that are used for project decision-making and parties involved in the transaction as: Project Developer/Sponsor, Tax equity investor, Debt investor, Energy buyer and Tax regulator. The study fulfils the knowledge gap in the decision making process that takes advantage of tax monetization in traditional after-tax analysis for renewable energy projects if the sponsors do not have the tax capacity to realize the total benefits of the project. A case-study for a wind farm, using newly emerging financial structures, validates the hypothesis that these renewable energy sources can meet energy industry economic criteria. The case study also helps to validate the following hypotheses: a) The greater a sponsor's tax appetite, the tower the sponsor's equity dilution. b) The use of leverage increases the cost of equity financing

    The core objective of the project RE-Shaping is to assist Member State (MS) governments in preparing for the implementation of Directive 2009/28/EC and to guide a European policy for RES in the mid- to long term. The past and present success of policies for renewable energies will be evaluated and recommendations derived to improve future RES support schemes. The effectiveness and the efficiency of current and future RES support schemes is analysed with specific focus on a single European market for renewable electricity products. Current best practices are identified, and (future) costs of RES and the corresponding support necessary to initiate stable growth are assessed. Better integration of RES policies with climate and innovation policy as well as liberalised energy markets will be analysed and promoted. Options for flexibility between Member States will be analysed. The future deployment of RES in each MS will be calculated based on the Green-X model to assist MS in implementing national action plans and to support a long term vision of the European RES policy. The latter will be based on an in-depth analysis of the long term RES potentials and costs. The impact of policies on risks for RES financing will be analysed and improved policies and financing instruments will be proposed.

    Full Text Available The ARBRE (ARable Biomass Renewable Energy project, the first large-scale wood-fueled electricity generating plant in the U.K., represents a significant development in realising British and European policy objectives on renewable energy. The plant is fueled by a mix of wood from short rotation coppice (SRC and forest residues. Where feasible, composted/conditioned sewage sludge is applied to coppice sites to increase yields and improve soil structure. In the Yorkshire Water region, typical total N:P:K composition of composted/conditioned sludge is 2.9:3.8:0.3, respectively. Sludge application is calculated on the basis of total nitrogen (N content to achieve 750 kg N ha-1, for 3 years’ requirement. Willow coppice forms a dense, widely spaced, root network, which, with its long growing season, makes it an effective user of nutrients. This, in combination with willow’s use as a nonfood, nonfodder crop, makes it an attractive route for the recycling of sewage sludge in the absence of sea disposal, banned under the EC Urban Waste Water Treatment Directive (UWWTD. Further work is required on the nutritional requirements of SRC in order to understand better the quantities of sludge that can be applied to SRC without having a detrimental impact on the environment. This paper suggests the source of N rerouting under the UWWTD and suggests the likely expansion of SRC as an alternative recycling pathway.

    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

    No single technology can solve the problem of ever increasing CO2 emissions from transport. Here, a coherent effort to integrate transport into energyplanning is proposed, using multiple means promoting sustainable 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 of food. The integration of the transport with the energy system is crucial as is a multi-pronged strategy. Short term solutions have to consider...... the long term goal. In a short term proposal for 2030 it is concluded that it is possible both to reduce CO2 emissions substantially and, at the same time, gain economic benefits. Biofuels are not able to solve the problems within the transport sector but play an important role in combination with other...

    Full Text Available In Poland, as in other European Union countries, the project finance structure is used to finance investments in the field of energy. This method investment financing is often used in the world. The upward trend inhibition in recent periods has been due to the global financial crisis and financial instability in the euro zone. On account of the necessity to develop the energy infrastructure associated with renewable sources, the considerable strengthening in the use of project finance techniques can be expected. The particular progression may be observed in the case of public-private partnership (ppp, where public investments are carried out by private companies. Companies, in case of investment realization in the field of ppp, almost always use project finance, because it is a beneficial way to separate the risks associated with an investment from the balance sheet of the compa-ny.

    The current share of renewable energy sources in electricity production in Croatia is very high, around 50%. Nevertheless it is expected that the share of renewables will have to rise and efficient strategies must be examined and adopted. The Croatian government has recognised the important role renewable energy sources could play in Croatian energy and electricity supply. The most important barrier for a wider deployment of renewables in energy production is their cost which is still above those of conventional energy sources. As the energy market is currently undergoing the process of liberalisation, support mechanisms that are compatible with an open market philosophy must be adopted. The characteristics of the Croatian power system, the expected consumption, growth and possible future role of renewables in energy and electricity production is presented. The current legislative framework relevant for renewables is analysed and discussed. (author)

    Ashworth, J.H.; Neuendorffer, J.W.

    1980-06-01

    This report provides a five step process for matching alternative renewable energy technologies with energy needs in rural villages of developing countries. Analytic tools are given for each of the five steps as well as information that can be expected. Twelve characterization criteria are developed to assist in the matching process. Three of these criteria, called discrimination criteria, are used for preliminary screening of technology possibilities for each need. The other criteria address site-specific temporal, climatic, social, cultural, and environmental characteristics of the energy need, technology, and cost considerations. To illustrate the matching process, seven basic human needs for energy are matched with seven potential renewable energy technologies. The final portion of the paper discusses the advantages of such a matching process and the resources required to initiate such an effort within a development project. Specific recommendations are given for field-testing this process and actions that could be taken immediately in basic research and development, applied research and technology modification, demonstrations, and commercialization to assist in the future diffusion of renewable energy technologies to rural areas of developing countries.

    When electricity is generated - either from a renewable or non-renewable power plant - the electrons added to the grid are indistinguishable. So, on what basis can a consumer of electricity claim to be using renewables? In the United States, renewable energy certificates (RECs) were developed as states passed renewable portfolio standards (RPSs) and were requiring fuel mix disclosure labels. RECs are also used in the voluntary market, where customers are buying renewables to meet sustainability goals. The concept of RECs is used most widely in the United States, but international markets also have tradable renewable electricity certificates. This fact sheet reviews how to ensure that RECs are not double-counted, roles of electricity regulators, renewable generators and purchasers. It concludes with a discussion of the international use of RECs.

    2012-01-15

    Over the past years, interest has grown in the potential for the renewable energy industry to create jobs. Governments are seeking win-win solutions to the dual challenge of high unemployment and climate change. By 2010, USD 51 billion had been pledged to renewables in stimulus packages, and by early 2011 there were 119 countries with some kind of policy target and/or support policy for renewable energy, such as feed-in tariffs, quota obligations, favourable tax treatment and public loans or grants, many of which explicitly target job creation as a policy goal. Policy-makers in many countries are now designing renewable energy policies that aim to create new jobs, build industries and benefit particular geographic areas. But how much do we know for certain about the job creation potential for renewable energy? This working paper aims to provide an overview of current knowledge on five questions: (1) How can jobs in renewable energy be characterised?; (2) How are they shared out across the technology value chain and what skill levels are required?; (3) How many jobs currently exist and where are they in the world?; (4) How many renewable energy jobs could there be in the future?; and (5) What policy frameworks can be used to promote employment benefits from renewable energy? This paper focuses on grid-connected electricity generation technologies and biofuels. Since the employment potential of off-grid applications is large, it will be covered by a forthcoming study by IRENA on job creation in the context of energy access, based on a number of case studies.

    Among the regulatory policies, feed-in tariffs (FIT) and renewable portfolio standards (RPS) are the most popular to promote the development of renewable energy power industry. They can significantly contribute to the expansion of domestic industrial activities in terms of sustainable energy. This paper uses system dynamics (SD) to establish models of long-term development of China's waste incineration power industry under FIT and RPS schemes, and provides a case study by using scenario analysis method. The model, on the one hand, not only clearly shows the complex logical relationship between the factors but also assesses policy effects of the two policy tools in the development of the industry. On the other hand, it provides a reference for scholars to study similar problems in different countries, thereby facilitating an understanding of waste incineration power's long-term sustainable development pattern under FIT and RPS schemes, and helping to provide references for policy-making institutions. The results show that in the perfect competitive market, the implementation of RPS can promote long-term and rapid development of China's waste incineration power industry given the constraints and actions of the mechanisms of RPS quota proportion, the TGC valid period, and fines, compared with FIT. At the end of the paper, policy implications are offered as references for the government. Copyright © 2017 Elsevier Ltd. All rights reserved.

    In the last quarter of this century, global environmental problem has emerged as a major scientific, political and social issue. Specific Problems include: depletion of ozone layer by chlorofluorocarbons (CFCs), acid rain, destruction of tropical forests and desertification, pollution of the sea and global wanning due to the greenhouse effect by carbon dioxide and others. Among these problems, particular attention of the world has been focused on the global warming because it has direct linkage to energy consumption which our economic development depends on so far. On the other hand, the future program of The Sunshine Project for alternative energy technology R&D, The Moonlight Project for energy conservation technology R&D, and The Global Environmental Technology Program for environmental problem mitigating technology R&D which are Japan`s national projects being promoted by their Agency of Industrial Science and Technology (AIST) in the Ministry of International Trade and Industry have been reexamined in view of recent changes in the situations surrounding new energy technology. In this regard, The New Sunshine Program will be established by integrating these three activities to accelerate R&D in the field of energy and environmental technologies. In the reexamination, additional stress has been laid on the contribution to solving global environmental problem through development of clean renewable energies which constitute a major part of the {open_quotes}New Earth 21{close_quotes}, a comprehensive, long-term and international cooperative program proposed by MITI. The present paper discusses the results of feasibility study on hydrogen energy system leading to the concept of WE-NET following a brief summary on R&D status on solar and wind energy in Japan.

  1. Emerging Markets for Renewable Energy Certificates: Opportunities and Challenges

    Energy Technology Data Exchange (ETDEWEB)

    Holt, E.; Bird, L.

    2005-01-01

    Renewable energy certificates (RECs) represent the attributes of electricity generated from renewable energy sources. These attributes are unbundled from the physical electricity, and the two products-the attributes embodied in the certificates and the commodity electricity-may be sold or traded separately. RECs are quickly becoming the currency of renewable energy markets because of their flexibility and the fact that they are not subject to the geographic and physical limitations of commodity electricity. RECs are currently used by utilities and marketers to supply renewable energy products to end-use customers as well as to demonstrate compliance with regulatory requirements, such as renewable energy mandates. The purpose of this report is to describe and analyze the emerging market for renewable energy certificates. It describes how RECs are marketed, examines RECs markets including scope and prices, and identifies and describes the key challenges facing the growth and success of RECs markets.

    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 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.

    Full Text Available Hydrogen produced by renewable sources represents an interesting way to reduce the energetic dependence on fossil fuels in the transportation sector. This paper shows a feasibility study for the production, storage and distribution of hydrogen in the western Sicilian context, using three different renewable sources: wind, biomass and sea wave. The objective of this study is the evaluation of the hydrogen demand, needed to replace all diesel supplied buses with electrical buses equipped with fuel cells. An economic analysis is presented with the evaluation of the avoidable greenhouse gas emissions. Four different scenarios correlate the hydrogen demand for urban transport to the renewable energy resources present in the territories and to the modern technologies available for the production of hydrogen. The study focuses on the possibility of tapping into the potential of renewable energies (wind, biomass and sea wave for the production of hydrogen by electrolysis. The use of hydrogen would reduce significantly the emissions of particulate and greenhouse gases in the urban districts under analysis.

    2006-11-28

    The Quinault Indian Nation (Nation) initiated this study on conservation and production of renewable energy because this approach created the opportunity: • To become self-sufficient and gain greater control over the energy the Nation uses; • To generate jobs and businesses for its members; • To better manage, sustain, and protect its resources; • To express the cultural values of the Nation in an important new arena. The Nation has relatively small energy needs. These needs are concentrated at two separate points: the Quinault Beach Resort and Casino (QBRC) and Taholah on the Quinault Indian Reservation (QIR). Except for the town of Queets, energy needs are small and scattered. The needs vary greatly over the season. The small scale, widely dispersed, and variable nature of these needs presents a unique challenge to the Nation. Meeting these needs requires a resource and technology that is flexible, effective, and portable. Conservation is the most cost-effective way to meet any need. It is especially effective in a situation like this where production would leave a high per unit cost. This plan is based on first gaining energy savings through conservation. Major savings are possible through: 1. Upgrading home appliances on the QIR. 2. Weatherizing homes and facilities. 3. Changes in lighting/ventilation in the QBRC pool room. These elements of the plan are already being implemented and promise to save the Nation around a quarter of its present costs. Wood biomass is the best resource available to the QIN for energy production either on-site or for commercial development. It is abundant, flexible and portable. Its harvesting has high job potential and these jobs are a good fit for the present “skill set” of the QIN. This plan focuses on using wood biomass to produce energy and other value-added products. Our study considered various technologies and approaches to using wood for energy. We considered production for both on-site and commercial production

    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.

    Public understanding of science (PUS) is a central concept among science communicators. Public understanding of renewable energy (PURE) is proposed as an important sub-concept of PUS. The aim of this paper is to interest and invite renewable energy scientists to join a PURE research project. Four separate important questions for a PURE research project can be identified: (A) Is PURE important? (B) Which issues of PURE are the most important ones, according to renewable energy scientists? (C) What understanding of renewable energy has the general public today, worldwide? (D) How to achieve PURE?.

  1. Role of Renewable Energy Certificates in Developing New Renewable Energy Projects

    Holt, E.; Sumner, J.; Bird, L.

    2011-06-01

    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.

    Renewable cooling technologies do not play a major role in the climate protection discussion in the European Union today. At the same time the cooling demand is expected to increase significantly in the coming decades. Renewable cooling technologies could contribute to the EU renewable energy target if an appropriate political framework for a further spread of the technologies is created. This renewable cooling policy report intends to support the dissemination of renewable cooling technologies. It provides an overview of the situation, technologies and potential for cool-ing from renewable sources and identifies key areas in which further investigation is required. The report shows that there is a great need for the creation of a political framework supporting the market diffusion of renewable cooling technologies. Firstly the question of a commonly accepted definition on renewable cooling is being addressed. Secondly renewable cooling technologies are described and the today's role of cooling in European statistics and policies is analysed. In the next step existing studies are evaluated to compare the expected development of the cooling demand in Europe to the market potential of renewable cooling. At the end of the paper a long-term vision for renewable cooling is described and first steps towards a European roadmap for renewable cooling are given.

  5. Leveraging Renewable Energies in Distributed Private Clouds

    Directory of Open Access Journals (Sweden)

    Pape Christian

    2016-01-01

    Full Text Available The vast and unstoppable rise of virtualization technologies and the related hardware abstraction in the last years established the foundation for new cloud-based infrastructures and new scalable and elastic services. This new paradigm has already found its way in modern data centers and their infrastructures. A positive side effect of these technologies is the transparency of the execution of workloads in a location-independent and hardware-independent manner. For instance, due to higher utilization of underlying hardware thanks to the consolidation of virtual resources or by moving virtual resources to sites with lower energy prices or more available renewable energy resources, data centers can counteract their economic and ecological downsides resulting from their steadily increasing energy demand. This paper introduces a vector-based algorithm for the placement of virtual machines in distributed private cloud environments. After outlining the basic operation of our approach, we provide a formal definition as well as an outlook for further research.

    This report represents an initial activity of the Bureau of Land Managements (BLM) proposed National Energy Policy Implementation Plan: identify and evaluate renewable energy resources on federal lands and any limitations on accessing them. Ultimately, BLM will prioritize land-use planning activities to increase industrys development of renewable energy resources. These resources include solar, biomass, geothermal, water, and wind energy. To accomplish this, BLM and the Department of Energys National Renewable Energy Laboratory (NREL) established a partnership to conduct an assessment of renewable energy resources on BLM lands in the western United States. The objective of this collaboration was to identify BLM planning units in the western states with the highest potential for private-sector development of renewable resources. The assessment resulted in the following findings: (1) 63 BLM planning units in nine western states have high potential for one or more renewable energy technologies; and (2) 20 BLM planning units in seven western states have high potential for power production from three or more renewable energy sources. This assessment report provides BLM with information needed to prioritize land-use planning activities on the basis of potential for the development of energy from renewable resources.

  16. National Renewable Energy Policy in a Global World

    Science.gov (United States)

    Jeong, Minji

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

    The IEA Implementing Agreement for Renewable Energy Technology Deployment (IEA-RETD) investigated the opportunities for coupling renewable energy systems with fresh water supply systems. The four main conclusions of the scoping study, carried out by Ecofys, are: (1) Fresh water production based on desalination technologies provide most options for synergies with renewable energy production; (2) Linking desalination to renewable sources is currently not economically viable; (3) There is a large potential for small scale (decentralised) desalination plants; (4) Current commercially-sized desalination technologies are in need of a constant operation point. Reverse osmosis and thermal membrane technologies might give future synergies as deferrable load.

    Full Text Available In the context of the European Union policy in the energy field on promoting the development of new and renewable energy forms, the Community legislation on the promotion of renewable sources had a significant development in the recent years. Thus, alternative fossil fuels (geothermal energy, ocean energy, hydropower energy, solar energy, wind energy, biomass and biofuels contribute to the diversification of the supply on energy to reduce the greenhouse gas emissions and reduce the dependence on fossil fuels markets. Moreover, in accordance with the specifications of the Directive 2009/28/EC on energy from renewable sources there has been set as compulsory target the fact that an amount of 20% of the energy consumption of the European Union by 2020, to be derived from the renewable energy sources. In turn, this objective is detailed in the secondary national compulsory targets given the different starting points of Member States. Based on these aspects, in our country, the unsubsidized renewable energy (hydroelectric, together with the photovoltaic, wind and biomass energy represented in the past three years a contribution well above the target assumed by Romania for the year 2020 of total of the produced energy. In this context, this study aims, on the one hand, to emphasize that the subsidized renewable energy to the captive consumers, by increasing the share of green certificates, results in narrowing the market of the classic manufacturers, on the other hand, to account for these securities as due to the existence of subsidies for the operating activities.

  13. Renewable energy recovery through selected industrial wastes

    Science.gov (United States)

    Zhang, Pengchong

    Typically, industrial waste treatment costs a large amount of capital, and creates environmental concerns as well. A sound alternative for treating these industrial wastes is anaerobic digestion. This technique reduces environmental pollution, and recovers renewable energy from the organic fraction of those selected industrial wastes, mostly in the form of biogas (methane). By applying anaerobic technique, selected industrial wastes could be converted from cash negative materials into economic energy feed stocks. In this study, three kinds of industrial wastes (paper mill wastes, brown grease, and corn-ethanol thin stillage) were selected, their performance in the anaerobic digestion system was studied and their applicability was investigated as well. A pilot-scale system, including anaerobic section (homogenization, pre-digestion, and anaerobic digestion) and aerobic section (activated sludge) was applied to the selected waste streams. The investigation of selected waste streams was in a gradually progressive order. For paper mill effluents, since those effluents contain a large amount of recalcitrant or toxic compounds, the anaerobic-aerobic system was used to check its treatability, including organic removal efficiency, substrate utilization rate, and methane yield. The results showed the selected effluents were anaerobically treatable. For brown grease, as it is already well known as a treatable substrate, a high rate anaerobic digester were applied to check the economic effect of this substrate, including methane yield and substrate utilization rate. These data from pilot-scale experiment have the potential to be applied to full-scale plant. For thin stillage, anaerobic digestion system has been incorporated to the traditional ethanol making process as a gate-to-gate process. The performance of anaerobic digester was applied to the gate-to-gate life-cycle analysis to estimate the energy saving and industrial cost saving in a typical ethanol plant.

    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.

    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.

    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. Discuss enabling technology development needs; 4. Identify analysis requirements, capabilities and gaps to estimate FOM for

    Variable energy resources, such as wind power, now produce about 4% of U.S. electricity. They can play a significantly expanded role if the U.S. adopts a systems approach that considers affordability, security and reliability. Reaching a 20-30% renewable portfolio standard goal is possible, but not without changes in the management and regulation of the power system, including accurately assessing and preparing for the operational effects of renewable generation. The RenewElec project will help the nation make the transition to the use of significant amounts of electric generation from variable and intermittent sources of renewable power.

    The role of citizens as innovators, adaptors of existing technologies and diffusers of new climate-relevant innovations has been studied extensively in recent years. Since the late 1970s, sociological and demographic research on residential energy use has consistently found great variations in energy use among similar households. It has been suggested that these variations constitute a source of innovative low-carbon practices. Yet, while there are many generic technologies available for end-use efficiency and renewables, their slow rate of diffusion suggests that they are not as such applicable to local conditions. Citizens have a key role in their adoption and adaptation to local conditions, as well in their diffusion to other users. Against this backdrop, the track 4 of NCF called for poster presentations of innovative new products, modifications of existing products, news ways of make use of existing technologies as well as such living practices that reduce energy use or enable the utilization of renewable energy sources in domestic settings in the Nordic countries.

Renewable energy sources include 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 629 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. The majority (64 per cent) of Canada's total installed power capacity comes from renewable energy sources, with the dominant source being hydroelectricity. Manitoba has the highest portion of renewable energy at almost 98 per cent of its installed electrical capacity. Nearly half of Canada's renewable power capacity is in Quebec, followed by 18 per cent in British Columbia. Nova Scotia has Canada's only tidal power plant. Approximately 80 per cent of the total installed renewable energy power capacity in Canada is owned by integrated electric utilities. Eleven per cent is owned by renewable electricity generating companies, 5 per cent is owned by aluminium companies, and 3 per cent is owned by pulp and paper companies. The rest is owned by diversified electricity generators. It is expected that with the ratification of the Kyoto Protocol interest in renewable energy will grow. 6 refs., 3 tabs., 2 figs., 1 appendix.

    Science.gov (United States)

    Şahin, Sümer

    2014-09-01

    Renewability and sustainability aspects of nuclear energy have been presented on the basis of two different technologies: (1) Conventional nuclear technology; CANDU reactors. (2) Emerging nuclear technology; fusion/fission (hybrid) reactors. Reactor grade (RG) plutonium, 233U fuels and heavy water moderator have given a good combination with respect to neutron economy so that mixed fuel made of (ThO2/RG-PuO2) or (ThC/RG-PuC) has lead to very high burn up grades. Five different mixed fuel have been selected for CANDU reactors composed of 4 % RG-PuO2 + 96 % ThO2; 6 % RG-PuO2 + 94 % ThO2; 10 % RG-PuO2 + 90 % ThO2; 20 % RG-PuO2 + 80 % ThO2; 30 % RG-PuO2 + 70 % ThO2, uniformly taken in each fuel rod in a fuel channel. Corresponding operation lifetimes have been found as ˜ 0.65, 1.1, 1.9, 3.5, and 4.8 years and with burn ups of ˜ 30 000, 60 000, 100 000, 200 000 and 290 000 MW.d/ton, respectively. Increase of RG-PuO2 fraction in radial direction for the purpose of power flattening in the CANDU fuel bundle has driven the burn up grade to 580 000 MW.d/ton level. A laser fusion driver power of 500 MWth has been investigated to burn the minor actinides (MA) out of the nuclear waste of LWRs. MA have been homogenously dispersed as carbide fuel in form of TRISO particles with volume fractions of 0, 2, 3, 4 and 5 % in the Flibe coolant zone in the blanket surrounding the fusion chamber. Tritium breeding for a continuous operation of the fusion reactor is calculated as TBR = 1.134, 1.286, 1.387, 1.52 and 1.67, respectively. Fission reactions in the MA fuel under high energetic fusion neutrons have lead to the multiplication of the fusion energy by a factor of M = 3.3, 4.6, 6.15 and 8.1 with 2, 3, 4 and 5 % TRISO volume fraction at start up, respectively. Alternatively with thorium, the same fusion driver would produce ˜160 kg 233U per year in addition to fission energy production in situ, multiplying the fusion energy by a factor of ˜1.3.

    1997-03-01

    Energy use accounts for the dominating fraction of total sulphur dioxide (SO{sub 2}), nitrogen oxide (NO{sub x}), volatile organic compounds (VOCs) and carbon dioxide (CO{sub 2}) emissions. In this thesis, different strategies for reducing these emissions are evaluated, using a bottom-up approach. CO{sub 2} emissions from electricity and heat production in western Scania, Sweden, can be reduced by 25% and the emissions of acidifying gases (SO{sub 2} and NO{sub x}) by 50% by the year 2010, compared with 1988 levels, using energy systems based on efficient end-use technologies, cogeneration of heat and electricity, renewable energy sources and low-pollution energy conversion technologies. Exhaust-pipe NO{sub x} emissions from the Swedish transportation sector can be reduced by 50 percent by the year 2015, compared with 1991, by implementing the best available vehicle technologies. Exhaust-pipe emissions of CO{sub 2} can be stabilized at the 1991 level. With further technical development and the use of fuels from renewable sources of energy, NO{sub x} emissions can be reduced by 75 percent and CO{sub 2} emissions by 80 percent compared with 1991 levels. Swedish biomass resources are large, and, assuming production conditions around 2015, about 200 TWh/year could be utilised for energy. Major reductions in CO{sub 2} emissions could be achieved by substituting biomass for fossil fuels in heat, electricity and transportation fuel production. Transportation fuels produced from cellulosic biomass are likely to be less expensive than transportation fuels from conventional biomass feedstocks such as oil plants, sugar-beet and cereals. 90 refs, 3 figs, 5 tabs

  9. Renewable energy-driven innovative energy-efficient desalination technologies

    KAUST Repository

    Ghaffour, Noreddine

    2014-04-13

    Globally, the Kingdom of Saudi Arabia (KSA) desalinates the largest capacity of seawater but through energy-intensive thermal processes such as multi-stage flash (MSF) distillation (>10 kW h per m3 of desalinated water, including electrical and thermal energies). In other regions where fossil energy is more expensive and not subsidized, seawater reverse osmosis (SWRO) is the most common desalination technology but it is still energy-intensive (3-4 kW h_e/m3). Both processes therefore lead to the emission of significant amounts of greenhouse gases (GHGs). Moreover, MSF and SWRO technologies are most often used for large desalination facilities serving urban centers with centralized water distribution systems and power grids. While renewable energy (RE) sources could be used to serve centralized systems in urban centers and thus provide an opportunity to make desalination greener, they are mostly used to serve rural communities off of the grid. In the KSA, solar and geothermal energy are of most relevance in terms of local conditions. Our group is focusing on developing new desalination processes, adsorption desalination (AD) and membrane distillation (MD), which can be driven by waste heat, geothermal or solar energy. A demonstration solar-powered AD facility has been constructed and a life cycle assessment showed that a specific energy consumption of <1.5 kW h_e/m3 is possible. An innovative hybrid approach has also been explored which would combine solar and geothermal energy using an alternating 12-h cycle to reduce the probability of depleting the heat source within the geothermal reservoir and provide the most effective use of RE without the need for energy storage. This paper highlights the use of RE for desalination in KSA with a focus on our group\\'s contribution in developing innovative low energy-driven desalination technologies. © 2014 Elsevier Ltd.

    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

  12. Energy Storage Applications in Power Systems with Renewable Energy Generation

    Science.gov (United States)

    Ghofrani, Mahmoud

    In this dissertation, we propose new operational and planning methodologies for power systems with renewable energy sources. A probabilistic optimal power flow (POPF) is developed to model wind power variations and evaluate the power system operation with intermittent renewable energy generation. The methodology is used to calculate the operating and ramping reserves that are required to compensate for power system uncertainties. Distributed wind generation is introduced as an operational scheme to take advantage of the spatial diversity of renewable energy resources and reduce wind power fluctuations using low or uncorrelated wind farms. The POPF is demonstrated using the IEEE 24-bus system where the proposed operational scheme reduces the operating and ramping reserve requirements and operation and congestion cost of the system as compared to operational practices available in the literature. A stochastic operational-planning framework is also proposed to adequately size, optimally place and schedule storage units within power systems with high wind penetrations. The method is used for different applications of energy storage systems for renewable energy integration. These applications include market-based opportunities such as renewable energy time-shift, renewable capacity firming, and transmission and distribution upgrade deferral in the form of revenue or reduced cost and storage-related societal benefits such as integration of more renewables, reduced emissions and improved utilization of grid assets. A power-pool model which incorporates the one-sided auction market into POPF is developed. The model considers storage units as market participants submitting hourly price bids in the form of marginal costs. This provides an accurate market-clearing process as compared to the 'price-taker' analysis available in the literature where the effects of large-scale storage units on the market-clearing prices are neglected. Different case studies are provided to

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