    This comprehensive report for the Swiss Federal Office of Energy (SFOE) presents the results obtained from an analysis of the formation of so called 'clusters' of companies acting in related fields with the aim of enhancing innovation in their business areas. This is achieved by promoting the exchange of knowledge to encourage learning processes. The report discusses the pros and cons of the 'cluster' theory as well as experience gained in this area in various European countries. It also suggests measures to be taken to aid the formation and further development of clusters in Switzerland. The measures looked at include political ones on the demand side such as levies, energy standards, export promotion and the setting of examples by authorities and - to a lesser degree - measures on the supply side such as the support of research. In particular, the successful use of the 'cluster' method in Austria is looked at.

    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.

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

    The development of the use of renewable energy sources in Germany in 2011 significantly was influenced by the disaster in Fukushima (Japan) and the change of course in the German energy policy. In addition, there is the amendment of the Renewable Energy Law (EEG) in an increasingly controversial area of tension between climate protection, energy utilization, cost minimization and considerations on sustainability. With this in mind, the authors of the contribution under consideration report on developments in Germany in the year 2011 in the field of energy supply and fuel supply from renewable energies. Beside the energy-economic framework conditions for the various possibilities for the use of renewable energies, the current status, developments and prospects are analysed. The contribution gives an outlook on the possible expansion of the supply of renewable energies in 2012.

    The use of renewable energy has experienced in Fukushima Prefecture in the years after the reactor accident in March 2011, a substantial upswing. In total 500 MW of renewable energy capacity have been installed. According to the plans of the prefecture this capacity should be increased in 2020 to a total of just over 8 gigawatts. As in the rest of the country parts also, the solar energy was primarily used; this accounted 295 MW alone. In future, the priorities but more are in the areas of wind energy and hydropower. [German] Der Einsatz erneuerbarer Energien hat in der Praefektur Fukushima in den Jahren nach dem Reaktorunglueck vom Maerz 2011 einen erheblichen Aufschwung zu verzeichnen. Insgesamt wurden 500 MW erneuerbare Energie Leistung installiert. Nach den Plaenen der Praefektur soll diese Kapazitaet bis 2020 auf insgesamt gut 8 Gigawatt gesteigert werden. Wie in den uebrigen Landesteilen auch, kam bisher vorwiegend die Solarenergie zum Zuge; diese machte allein 295 MW aus. Kuenftig sollen die Schwerpunkte jedoch staerker in den Bereichen von Windenergie und Wasserkraft liegen.

    The ISET ended the 10th anniversary year since its foundation in 1998 with already the third Kassel symposium on energy-related system engineering: renewable energy sources and rational energy use. Covering several special subjects talks were given about the topics modelling and simulation in the fields of wind energy, photovoltaic systems, hybrid systems or sewage water treatment. The keen interest of the participants shows the importance that modelling of conditions or processes has gained in the meantime in the field of system engineering of renewable energy sources. The core of each simulation is the integration of differential equations, which describe the system. Properties of the system can be easily varied and affects on the overall system can be easily investigated. Critical conditions can be discovered and be taken into consideration at the hardware engineering. Mistakes in terms of component design can be avoided and engineering cost can be reduced considerably. The present conference book gives an ideal overview of the topics discussed during the symposium. (orig.) [German] Sein Jubilaeumsjahr zum zehnjaehrigen Bestehen beschloss das ISET 1998 mit dem nun bereits 3.

Fachgebietsuebergreifend wurde zu den Themen Modellbildung und Simulation in Bereichen wie Windenergie, Photovoltaik, Hybridsysteme oder Abwasserbehandlung referiert. Das rege Interesse der Teilnehmer unterstreicht die Bedeutung, die die Modellierung von Zustaenden oder Prozessen in der Systementwicklung bei den erneuerbaren Energien inzwischen gewonnen hat. Der Kern einer jeden Simulation ist die Integration der systembeschreibenden Differentialgleichungen. Eigenschaften des Systems koennen in einfacher Weise variiert und die Auswirkungen auf das Gesamtsystem untersucht werden.

    In April 2015, the French National Energy Agency ADEME has published a study on the potential and cost of electricity mix of 100% renewable energy in France. The scenarios for France confirm the current state of scientific knowledge: The full cost of a system, which is fully covered by renewable energies are not higher than those of conventional energy mix, even taking into account storage and network expansion costs. Security of supply can be ensured even under extremely adverse weather conditions permanently at any time. [German] Im April 2015 hat die staatliche franzoesische Energieagentur ADEME eine Studie zu den Potenzialen und Kosten eines Strommixes aus 100 % erneuerbaren Energien in Frankreich veroeffentlicht.

    Additional costs of the energy transition can only be termed when the present state of the power system is considered as a benchmark for future raised previous achievements. An energy policy that has an effective climate protection goal, must endeavor to change the market design of the energy market so as to align the price signals at the expense of those technologies that are able to provide energy without emissions and significant use of fossil resources. The derivable overall economic benefits of energy transition is significant. This is illustrated by the example of the differential cost for the annex of renewable energies in the electricity sector. A further development of renewable energy sources in combination with an effective electricity market design leads to an overall economic benefit of around 460 billion Euros in 2050. [German] Von zusaetzlichen Kosten der Energiewende kann nur gesprochen werden, wenn der heutige Zustand des Energiesystems als Massstab fuer zukuenftig aufzubringende Vorleistungen betrachtet wird. Eine Energiewende, die einen effektiven Klimaschutz zum Ziel hat, muss jedoch bestrebt sein, das Marktdesign des Energiemarkts so zu veraendern, dass sich die Preissignale an den Kosten derjenigen Technologien ausrichten, die in der Lage sind, Energie emissionsfrei und ohne wesentliche Inanspruchnahme fossiler Ressourcen bereitzustellen. Der daraus ableitbare gesamtwirtschaftliche Nutzen der Energiewende ist erheblich. Es wird hier am Beispiel der Differenzkosten des Zubaus erneuerbarer Energien im Stromsektor erlaeutert. Ein konsequenter weiterer Erneuerbare Energien-Zubau in Kombination mit einem effektiven Strommarktdesign fuehrt zu einem gesamtwirtschaftlichen Nutzen von rund 460 Mrd. Euro im Jahr 2050.

Renewable energy against the background of reduced conventional and nuclear power plant capacities increase also much the security of supply at the West German electricity market. [German] In den Jahren 2010 bis 2013 stieg der Anteil der Stromerzeugung aus Erneuerbaren Energien von ca. 17 auf 2 4 %. Fuer diesen Anteil fallen gegenueber konventioneller Erzeugung wesentlich erhoehte Stromerzeugungskosten an, die ueber die EEG - Umlage auf die Endverbraucher umgelegt werden. In der oeffentlichen Diskussion wird bei der Wertung dieser Kosten allerdings vielfach nicht beachtet, dass der rasante Anstieg des Anteils Erneuerbarer Energien zu einem Ueberangebot an Strom und daher zu sinkenden Strompreisen insgesamt fuehrte. Durch das Ueberangebot wurde der Trend der in den Jahren 2000 bis 2008 stark steigenden Strompreise an den Europaeischen Strommaerkten gebrochen. Ziel dieses Diskussionspapiers ist es, auf Grundlage historischer Preisdaten des Spotmarktes der Leipziger Stromboerse zu rekonstruieren, welche Preise sich an der Stromboerse in den Jahren 2011 bis 2013 ohne die Einspeisung aus Wind und Photovoltaik eingestellt haetten. Die Analyse zeigt, dass sich im ''Day - Ahead'' - Handel des Spotmarktes die Strompreise ohne Wind und Sonne beispielsweise fuer das Jahr 2013 aufgrund des erheblich geringeren Stromangebots im Mittel um 5,2 9 ct/kWh erhoeht haetten. Den Kosten der EEG - Umlage von ca. 20,4 Mrd. Euro stehen also in 2013 Einsparungen fuer konventionell erzeugten Strom von ca. 31,6 Mrd. Euro gegenueber. Dies sparte fuer die deutschen Letztverbraucher 2013 insgesamt ca. 11,2 Mrd. Euro ein. Ueber 269 Stunden des Jahres haette die Nachfrage mit der maximal im Jahr 2013 angebotenen Leistung nicht gedeckt werden koennen.

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

    In August 2007 the German government agreed on the Integrated Energy and Climate Package (IECP) at Meseberg. This IECP-Macro study analyses the macroeconomic impacts of the IECP in Germany. The focus of analysis in IECP-Macro was on macroeconomic indicators, in particular on gross domestic product (GDP), consumption, investment and employment. This study links a bottom-up analysis of single policy measures with a macroeconomic analysis. The bottom-up impacts are fed into the ASTRA model, in which they trigger the macroeconomic impacts, e.g. a change of final demand in terms of investment or consumption. In total five scenarios have been analysed and have been compared with a reference scenario of the ASTRA model that has been aligned with the business-as-usual scenario of the project ''Politics Scenarios IV''. The basic conclusion of the analysis is that the economic stimulus of increased investment in climate policy stimulates economic growth in the short- and medium-term. Energy savings have the greatest effect to safeguard or even increase employment in the long run. (orig.)

    The energy policy of a state, at least a free and constitutional state like Germany, must always aim in two directions. First, of course, there are the envisaged energy policy goals. But on the other hand the legally protected interests of the private actors of the energy sector must be considered who will be touched by the energy policy measures. The authors show how these two considerations are combined in German energy law. (orig.)

    The German federal states play an important role in the progressive expansion of renewable energies and the success of the energy turnaround as a whole. Ultimately the energy turnaround has to happen locally. The federal states have considerable leeway at their disposal to this end. A recent comparative survey shows which states have undertaken the greatest efforts and which have had the greatest success in the area of renewable energies.

    This report for the Swiss Federal Office of Energy (SFOE) aims at determining the potential of improved feed-in forecasts for new renewable energies (NRE) in Switzerland. The characteristics of the Swiss energy market are considered. Benefits of and potential for improvement are identified and recommendations for additional measures to be taken are given. The authors note that at present the forecast systems for wind energy are quite sophisticated, while there is room for improvement for solar energy and micro hydro unit forecasts. Ways of improving the forecasts are discussed. The business case developed within the framework of this project is to be completed and quantified as soon as data for 2009 is provided by the regulatory body 'swissgrid' and the balance group for renewable energies. The report is completed with recommendations for further work.

    The ''Energiewende'' (energy turnaround) and the expansion of renewable energies in Germany is at a point, where, beside the undisputable successes and future opportunities, the problems and conflicts around renewable energy production have become increasingly apparent. The challenge today lies in the further development of the successfully implemented political instruments and of the underlying governance structures. This article summarizes the most important findings of the report as policy recommendations.

    In its energy plan from September 2010, the Federal Government has developed an overall strategy for a secure, payable and environmentally friendly energy supply to 2050. The results in Japan will accelerate the shift to renewable energies. The key to alternative energy sources is the transformation of our energy infrastructure by expanding the classical high-voltage lines, the creation of large-scale overlay connections on land and HVDC sea cable connections. In Germany, TenneT TSO GmbH (Bayreuth, Federal Republic of Germany) is mostly affected by the additional construction of wind turbines and therefore especially demanded to develop the existing transport network. This requires both national and European solutions.

    A stronger use of renewable energies is the key for an economically sustainable, social and ecological development. Therefore, the European Union decided exemplary targets of climatic protection such as a distinct increase of the energy efficiency and use CO{sub 2} reduced technologies for the development of renewable energies. Under this aspect, the contribution under consideration examines how free terrains can be supplied to a meaningful urban use, a recycling and a possible intermediate use. How large is the potential of free terrains for renewable energies in the future? How can renewable energies be won for suitable free terrains? Scenarios are developed for four model rooms. These scenarios aim to a gradual approach to an optimal supply of heat and electricity. The power requirement of the inhabitants of a city can be produced in the urban space. An energy document of identification for cities is suggested in order to enable a comparison of the cities among themselves. In the sense of a sustainable energy management, the existing stock also has to be used energetically.

    The renewable energy sector has become one of the great hopes of the German economy over the past years. The consistency of its development towards becoming an important economic factor became especially apparent during the economic crisis. The German Federal Republic plans to largely convert its energy supply to renewable resources in the future. The nuclear disaster in Japan and the public fear of nuclear radiation have added momentum to the change. The federal and state administrations are working to drive climate protection initiatives through numerous promotion programmes and are targeting subsidies to investments in renewable energy. The financing of energy production from wind power, solar energy and biomass has opened up a new and expanding business field for credit institutions. For all its potential, lack of knowledge of the economic conditions governing the energy sector and of financing options creates considerable obstacles in this area. This book presents the various types of renewable energy and the most common financing methods used for realising these projects.

    This comprehensive work report for the Swiss Federal Office of Energy (SFOE) made by the Paul Scherrer Institute PSI takes a look at work done in connection with the updating of the office's Energy Perspectives. In particular, the topic of electricity is reviewed in the light of pending important decisions in the area of nuclear energy and the newer renewable sources of energy. The report makes an attempt to estimate the effect on Swiss power production that the new renewables and new nuclear installations could have in the next 30-40 years and to what costs this could be done and which obstacles would have to overcome. The renewable energy sources include small hydro, wind, photovoltaics, solar thermal power plants, biogas, geothermal energy, wave-power and solar chemistry. The methods used include literature study and contacts with internal PSI experts on the various areas involved. The most important system characteristics were noted and learning curves for the various technologies were taken into account. Ecological and social factors were also considered

    The countries of the EU have jointly set themselves the goal of increasing the share of renewable energies in total end energy use to at least 20% by the year 2020. The member states are to define differentiated target values on the basis of national action plans. However, too little use is being made of the opportunities for concerted action that are available to the EU. By acting jointly the member states could make visions for renewable energies come true which would remain utopian if each country went it on its own. Now a new European Community for Renewable Energy - ERENE for short - is to make this a real possibility. The task of ERENE will be not only to envision the potentials at the national level for a complete conversion of the electricity sector to renewable resources but also to tap into these potentials by way of a joint strategy. Another is to create the framework conditions that are needed in order to make optimal use of the geological, climatic and hydrological diversity and hence the diversity and heterogeneous distribution of renewable energy resources within the EU.

    With the presentation of this report, an attempt is made for the first time to provide the interested public with a survey about ongoing projects and investigations carried out at universities and colleges, dealing with subjects in the associated field and sphere of influence regarding renewable energy sources. These considerations even go beyond the sponsorship through the BMFT (Federal Ministry for Research and Technology). An efficient science which rapidly takes up new subjects is especially important for a successful solar energy utilization. Initiatives from private industry and science in the field of application oriented fundamental research are necessary to help to further spread solar technology. With this, especially those works are of importance that are oriented to photovoltaic, photochemical, photo-electrochemical as well as to electrochemical investigations. The present description shows in an impressive way that numerous institutes and scientists, even in fields which are not solar specific such as crystallography, metallurgy, surface phsics, material science, physical chemistry or meteorology, this means fundamental research in the broadest sense, presently increasingly deal with subjects which might contribute to open important impetus and promising future perspectives for renewable energies and efficient energy utilization by means of materials with new unknown properties, innovative procedures and cost-effective manufacturing processes or improved design and prediction methods for example.

    This report for the Swiss Federal Office of Energy (SFOE) examines financing instruments that are already available in selected European countries and which could also be adapted for use in Switzerland, too. The study is limited to European countries that are comparable with Switzerland in terms of size, geography and gross national product. Further limitations are investment volumes of under 20 million Euro/project and the consideration of only those technologies concerned with the production of electrical power. Thus, the report considers biogas, solar, geothermal and small-hydro technologies in France, Austria, Denmark, Germany, Italy, Norway, Belgium and Switzerland. External and internal financing is considered as well as mezzanine capital. Varying taxation in the various countries is looked at as is the contracting/leasing situation and subsidies available for renewable energy projects. Risk management is discussed. Finally, the transferability of the various financing instruments to Switzerland is examined. Suggestions are made on how small and medium-sized enterprises can be supported in an active and growing Swiss market.

    With the support of the FORSCHUNGSVERBUND SONNENENERGIE (RESEARCH ASSOCIATION SOLAR ENERGY) and the VDE association of the district Kassel the Institute for Solar Energy Supply Technology (ISET) managed to close a gap in the list of events dealing with electric energy supply including the use of renewable energies. Another considerable increase in the number of participants at the 2nd Kassel symposium on energy systems technology compared to the previous year confirms the chosen direction and the selected major topic of discussion. Numerous studies - among others those from Shell, Esso and BP - predict the competitiveness of renewable energies in the next 20 to 30 years. Their share in the consumption of primary energies will increase considerably until the year 2005. Two tendencies can be noticed in the expansion of renewable energies in the field of electric current generation. On the one hand the increasing number of private as well as commercial offers of decentrally generated electric power leads to a higher supply into the public grid. On the other hand renewable energy carriers are more and more used for an autonomous energy supply in regions, which are not connected to the grid. In order to foster both tendencies and to support the combination of different approaches not only technical requirements but also the interfaces of components must be clearly defined. (orig.) [German] Mit Unterstuetzung des FORSCHUNGSVERBUND SONNENENERGIE, und des VDE Bezirksvereins Kassel ist es dem ISET gelungen, eine Luecke im Veranstaltungsangebot zur elektrischen Energieversorgung mit Einbindung erneuerbarer Energien zu schliessen.

    The power supply must integrate in the future an increasing share of renewable energies for the supply of electricity customers to meet the climate protection requirements. The proportion of weather-dependent renewable energy plays a leading role of renewable power supply in the future. These highly volatile provided electricity volumes do not match in base-load power generated amounts, as it has come in the past biogas park and still mostly delivers. It seems necessary that the non-fluctuating production units ''make room'' the wind and PV electricity volumes in the energy system and provide the electricity in phases when the fluctuating renewable energy electricity volumes are not available. In this study, it is determined how the biogas park with its high number of production systems should behave from total cost perspective in the energy system in 2030. It primarily concerns the question whether the base-load electricity production of biogas parks should be changed and made more flexible from the perspective of the overall costs and if so, to what extent. [German] Die Stromversorgung muss in Zukunft einen stetig steigenden Anteil an Erneuerbarer Energien zur Versorgung der Stromkunden integrieren, um die den Klimaschutzanforderungen zu genuegen. Der Anteil an wetterabhaengigen Erneuerbaren Energien nimmt dabei zukuenftig die tragende Rolle der Erneuerbaren Stromversorgung ein. Diese sehr volatil bereitgestellten Strommengen passen nicht zu in Grundlast erzeugten Strommengen, wie sie in der Vergangenheit der BiogasPark geliefert hat und immer noch groesstenteils liefert. Es scheint erforderlich, dass die nicht fluktuierenden Erzeugungseinheiten den Wind-und PV-Strommengen im Energiesystem ''Platz machen'' und den Strom in Phasen bereitstellen, wenn die fluktuierende Erneuerbaren Energie-Strommengen nicht zur Verfuegung stehen. Im Rahmen dieser Arbeit wird ermittelt, wie sich der BiogasPark mit seiner hohen Zahl an

    The expert opinion for the German Federal Environmental Agency explains and discusses the results of six scenarios describing the outcome of substitution of conventional electricity generation technologies relying exclusively on fossil fuels, using as a reference case the generation of middle load power in Germany in 1998 with the then operating German power plants, as well as projections for the year 2001. One major objective of the expert opinion is to evaluate results in terms of social and other relevant costs, achieved through the use of renewable energy technologies for electricity generation since effectiveness of the German EEG, (act promoting power generation from renewable energy sources). The comparative evaluation distinctly refers to conventional and renewable generation technologies in assessing their economic and environmental impacts. The second aspect analysed is the support (and its efficiency) offered so far by the existing national policies and laws, as well as the European Directives and guidelines on promotion of renewable energy technologies. Proposals for improvement are presented. (orig./CB) [German] Im Gutachten werden sechs Szenarien fuer die substituierte konventionelle Stromerzeugung entwickelt, die als Basis sowohl die durchschnittliche Stromerzeugung unter Verwendung fossiler Brennstoffe als auch die Erzeugung von Mittellaststrom fuer die Jahre 1998 und 2010 betrachten und anhand entsprechender Referenzsysteme und Berechnungen die Ergebnisse liefern, die die Frage nach allen relevanten, seit Einfuehrung des EEG bis heute, durch den Einsatz erneuerbarer Energietraeger substituierten Kosten und umweltrelevanten Verbesserungen beantworten und detailliert schildern.

    The brochure ''Renewable Energies'' has been published for ten years now. During this time the technologies, the social conditions, the promotion instruments, and the knowledge about the ecological aspects of our energy supply have made great progress. We have learned that bold energy policies which prioritize renewable energy and energy efficiency are the best insurance against limited resources, climate threats, and supply failures in the face of the growing global energy demand. Only those economies which understand how to use energy intelligently will be able to play a leading role in the global economy in the medium to long term. For this reason, the German Federal Government bundled an extensive package of measures over the past few years that are effective in all areas of society. Germany has achieved an important milestone by amending the Renew able Energy Sources Act (EEG), since not only did this law initiate the rapid development of renewable energy in the electricity generation sector, but it also created a stable development framework for a healthy, innovative sector. This course of success should be continued. Our goal is extremely ambitious. At least 30 percent of our electricity should be generated through renewable sources in 2020 - in 2008 it was around 15 percent. This goal is solidly anchored in Paragraph 1 of the new EEG. After 2020, the share shall continuosly increase. In 2030, we might see a share of 50 % renewable electricity. We have also made great progress in the other energy sectors since the last edition of this publication in 2006. The Renewable Energies Heat Act and the considerably increased market incentive programme are the starting points for doubling the production of heat from renewable energy sources by 2020. In the field of biofuels we stimulated important European discussions on the sustainable use of biogenic resources. The vascular system of a renewable energy system is the energy infrastructure - so we

    The depletion of fossil fuels and the accumulation of greenhouse gases, whose effects are already making themselves felt, are impacting not only on technical but also on societal and political developments around the globe. The human demand for energy from fossil fuels is growing worldwide, and the depletion of these reserves can already be clearly perceived. This is incidentally also true of nuclear fuels, at least for those reserves that are exploitable with currently available technology. The use of renewable energies such as wind power, solar energy, geothermal energy, hydropower and biomass - to name just a few - appears at present to offer a solution to the future problems relating to energy supply and environment (global warming and follow-on effects). The technologies required for this are already well-advanced today. Over a period of several years the authors have collected data and facts on global energy scenarios, evaluated countless studies, studied the technologies required for tapping renewable energy potentials and performed their own calculations on the topic.

    The majority of the German population is in support of the expansion of renewable energies. However, when it comes to construction work, project developers often meet with fierce opposition from the local population. One success factor in raising local acceptance of renewable energy production plants lies in planning projects such that citizens' interests and concerns are taken into account and well-conceived means of public participation are provided. Moreover, municipalities themselves can take on a pivotal role by becoming actively involved in the planning and development process and advertising renewable energy as a way towards municipal emancipation. This gives citizens less reasons to make a stand against such projects.

    The sixth Kassel symposium on energy system engineering. On-site energy generation using renewable energy sources focuses on the subject of innovative energy converter. The status and the development of generally known technologies is not only supposed to be reported on but also some conversion methods, which are currently not too well known. The changed frame conditions in the field of energy economy cause some systems, which have already been developed, to appear in a new light. The first talk of this symposium does not really discuss a method of energy conversion compared to the other talks. It rather describes a scenario that focuses on silicium as future energy carrier. Further contributions report on new, innovative concepts for electrical partial systems of wind and water power plants with variable revolution. Modern design methods for water turbines are presented with the example of hydraulic turbo-engines. Three contributions present the current status of technology and perspectives in the field of photovoltaics, thermal photovoltaics as well as new developments in the field of solarthermal systems. Talks about micro gas turbines and fuel cells discuss the use of these systems in dual purpose power plants and in the field of energy supply for houses. Information about modern steam engines and the use of Stirling engines in the field of biomass utilization complete the subject range of this symposium. (orig.) [German] Das 6.

    Germany lacks a unified register containing data on the equipment of hydropower stations with environmental facilities or of those subject to requirements for reducing the environmental impact on the status of waters. Thanks to the cooperation of the hydro-power plant operators, our survey allowed us for the first time to gain insight into the regulation effects of the German Renewable Energy Act (Erneuerbare-Energien-Gesetz; EEG) as well as into the ecological upgrade potential of German hydro-power plants. EEG 2004 and 2009 funded measures implemented at hydro-power stations are focused on ensuring a minimum flow as well as on longitudinal connectivity. This priority is consistent with the water management requirement of achieving the goals of the Water Framework Directive in this area. (orig.)

    This is a study of cost and benefits of the implementation of energy efficiency and renewable energy use in Switzerland, especially what regards job creation. The current status of renewable energy technologies is described, further studies dealing with similar issues are presented, and the potentials of renewable energy technologies are shown. The study exclusively considers the effect of the introduction of the so-called 'solar cent', a tax of 0.005 CHF/kWh suggested for all non-renewable energy sources. The tax should yield yearly about 880 millions Swiss francs to be re-invested in favour of energy conservation and renewables. The study is stimulating the discussion on the issue in whole Central Europe. For Switzerland, it is concluded that the proposed energy tax will induce an investment volume of 5.5 to 9.4 times the tax yield. This will create yearly 60,000 to 210,000 new jobs, a small fraction of them in countries exporting goods and services to Switzerland. On the other hand, this will suppress jobs in the oil-, gas-, and electric-power-related economic sectors. In the end, the net job creation would amount to 63,000 (average value from several different calculations). Principally, there is no technical nor financial obstacles to such a policy. However, considerable changes are required what regards the economy, the laws and the institutions related to the energy sources involved. The study was conducted in close co-operation by the Swiss Federal Office of Energy, an independent European scientific institute, several universities, representatives of innovative industry sectors, and non-governmental organisations.

    This study analyses the economic relevance of renewable energy in Switzerland. In 2010 the enterprises in the renewable energy sector generated a gross value added of 4.8 bn CHF (equalling 0.9% of Swiss GDP). Employment in this sector approximated 22,800 fulltime jobs (0.6% of total Swiss employment). Including supply chain companies, 1.5% of Swiss GDP and 1.2% of total employment can be related to the use of renewable energy. Exports of renewable energy related goods and services equalled 3.2 bn CHF. Since 2000 the Swiss renewable energy sector has experienced an above-average annual growth of more than 4%. Its potential development until the year 2020 was studied with two scenarios. In the policy scenario, that assumes additional policy measures for renewable energy promotion, direct value added of the renewable energy sector would amount to 6.4 bn CHF (+33%), direct employment would increase to 29,200 fulltime jobs (+28%, gross effects resp.). In the more conservative baseline scenario, growth would be much weaker, but still slightly stronger than anticipated for the average economy. (authors)

    Germany is an international leader in the development and introduction of renewable energy, i.e. wind and solar (photovoltaic) energy. Both technologies already contribute more than 13 % to national electricity generation. The political support of renewable energies resulted in a variety of different technologies the development of which has not yet been exhausted. The paper describes the state of the art of these technologies as well as selected development tendencies. New technologies can be introduced in a highly developed society only if questions according to their environmental impact are also answered.

    Liberalisation of the electricity sector aims to carry out coordination tasks within the system by markets and market prices. This study examines how markets need to be designed to carry out coordination tasks caused by integration of renewable energies in an efficient way. This question is applied to the German electricity system and recommendations are derived from identified deficits. The examination uses the structure-conduct-performance approach of industrial organisation economics. Integration of renewable energies does not result in entirely new coordination tasks but complicates those that exist in any electricity supply system. Within the short-term coordination tasks provision and operation of reserve capacity is affected by renewable energies. Long-term coordination means that the relation between fixed and variable costs of generators as well as generator flexibility has to be adjusted to the characteristics of renewable energies. The relevant short-term coordination task with the network is congestion management. In the long run costs of grid expansion and permanent congestion management have to be balanced. For the execution of short-run coordination tasks integrated and centralised market architectures are superior to decentralised architectures. The increase of short-term coordination tasks due to renewable energies caused by inflexibilities of consumers and conventional generators results in more information that has to be considered. By centralising that information in one market, an increase in productive efficiency can be obtained. In Germany the increased coordination tasks are determined by the integration of wind generators into the electricity system. The present German market architecture results in inefficiencies in short-term coordination. This is demonstrated by an analysis of procedural rules and prices of the ancillary service markets. They demonstrate that market performance is low and significant deviations from competitive prices

    This comprehensive final report for the Swiss Federal Office of Energy (SFOE) presents the findings of a project that examined large heat generation systems used in Switzerland for the supply of heating services to several buildings via small and large district heating systems. Focus is placed on those using fossil fuels and the potential of using combined heat and power plants and renewable forms of energy such as heat-pumps and boilers fired with wood-chippings. The study was also extended to other large-scale, fossil-fuelled heating installations. The report discusses the setting up of a data base, the assessment of the potentials for fuel substitution, the economic viability of wood-fired systems and heat-pumps and the analysis of various factors that can obstruct the use of systems employing renewable forms of energy. Around 20 owners of large installations were interviewed on the subject. Strategic planning, studies, putting to tender, realisation and operation aspects are reviewed.

    District heating allows the utilization of biomass in low emission heating plants, the exploitation of solar energy and the seasonal storage of heat. If a sustainable energy supply system is to be created, district heating must not only be the system of choice for new housing districts but must also be retrofitted in existing settlements. The detailed analysis of a rural community shows that large segments of existing buildings can be connected to district heating systems even in regions with predominantly single dwellings and rural housing densities. The conditions necessary for establishing district heating systems are discussed. (orig.)

    Connecting systems with the public power network in compliance with the Renewable Energies Law (EEG) usually causes considerable costs. The law stipulates the costs of the network connection to be taken over by the operator of the system and costs of a network expansion which becomes necessary due to the connection to be paid by the operator of the network. This regulation, however, is just an initial orientation. Problems arise dealing with the details, particularly regarding the question of which measures to be classified as network connection and which as network expansion. The laws and corresponding material contain only little information and up to now, jurisdiction has also been approaching the subject only in a case-related way, refraining from general statements about defining network connection and network expansion.

    The purpose of the study is to develop by thorough analysis a policy and action plans to establish proper markets for renewable energy technologies and forms of energy, support competition among the relevant technologies and with conventional generation technologies, ensure increasing penetration of renewable electricity in the European internal market in compliance with the deregulated market regime, and achieve this aim with least possible public funding. The study therefore examines various monetary and regulatory instruments as well as additional supporting measures for suitability to open up growth paths for renewable energy generation technologies, accelerate the process of competitive further development, and put it on a stable basis providing for a planning horizon. The various instruments are analysed and evaluated, and recommendations are derived for further enhancement. The post-analysis evaluation work also encompasses measures implemented for the same purpose by a number of other EU member states. The general policy objective is to increase until the year 2010 the contribution of renewable energy technologies to total energy supplies in Germany to at least the twofold of the year 1999, and to guarantee dynamic growth beyond 2010. In order to derive information about the quantitative aspects, i.e. required public funding and efficiency of suitable instruments, two scenarios have been worked out to serve as the basis of analysis for the period until 2010. The first scenario called ''Measures to date'' describes activities and their outcome until 1999, and the second called ''Twofold increase'' is a forecasting scenario. To account for the distinct dissimilarity of conditions in the electricity and heat markets, different approaches are taken for the corresponding analyses. For the electricity sector, amendment of the laws on promotion of renewable energy technologies and intensive marketing activities for renewable

    The document presents an analysis of a governmental support programme for enhanced use of renewable energy technologies, installed for the period from 1994 to 1998. The '100 million Deutschmark programme' financed by the German Federal Ministry of Economics (BMWi) was intended to boost applications of renewable energy technologies in the residential and commercial sector. The objectives of the programme were to improve market penetration of renewable energy technologies, eg. by inducing a decline in costs, so as to bring those generation technologies closer to the break-even point of economic efficiency, or make them achieve economic efficiency on a broader basis through more widespread applications. The evaluation presented in the document was to show the programme's achievements with respect to the following aspects and criteria: Comparison with other governmental programmes, in particular those of Land governments. Indirect effects on employment, imports and exports, or in terms of incentives for technological enhancements. Assessment of direct effects on the marketing situation and the technologies. The conclusions drawn were to include recommendations for a successor programme.

    The global market for renewable energy technologies has experienced strong growth since the year 2000. In 2013 newly installed electricity production plants based on renewable energy for the first time outnumbered the aggregate of newly installed plants based on coal, gas or nuclear energy. In more and more parts of the world, wind and solar energy plants are becoming the most cost-effective means of electricity production. As renewable energy resources begin to claim significant shares in the energy mix they also become more system-relevant, resulting in a need for more investment as well as regulatory changes. Due to their specific features (high capital intensity, low incremental costs, fluctuating electricity production), and in spite of the marked decline in costs, wind and solar energy are still dependent on proactive policies in support of renewable energy.

    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.

In a not too far future, the millions of tourists that visit European archipelagos will have the occasion, apart of having holidays, of consuming electricity provenient from hybrid wind-photovoltaic minigrids, from wind-diesel systems, from wind-hydro systems, from wave energy power stations, or from fuel cells supplied by hydrogen produced in wind farms. (orig.) [German] Energie spielt eine lebenswichtige Rolle bei der umweltgerechten Entwicklung aller inseln. In naher Zukunft werden Millionen von Touristen, die die europaeischen Archipele besuchen, nicht nur die Moeglichkeit haben, ihren Urlaub an einem privilegierten Ort zu verbringen, sondern auch Elektrizitaet konsumieren. Diese wird an kleinen PV-Wind-Hybridnetzen, Wind-Diesel-Systemen, Wind-Pumpspeicherkraftwerken, Wellenenergieanlagen oder Brenstoffzellen mit Zufuhr von in Windparks produziertem Wasserstoff erzeugt werden.

    German politicians, industry and society are working on the 'energy turnaround'. While changes in centralized power generation and transmission are going slow, there is an increasing number of 'test laboratories' in rural regions as communities and villages abandon imported fossil fuels and generate their own power on the basis of solar, wind and geothermal resources. In his study, the author investigates the transition phase using tools of empirical sociology. He shows that local processes reflect the importance of the energy turnaround as a cultural change and as a full-scale transformation of rural regions. The development of local, decentral energy infrastructures is interpreted theoretically as an interdependence between social and technological compolexity. The further geographic diffusion of the model in German-language regions can thus be explained as a consequence of specific social structures.

    Overall the provisions of the German Renewable Energy Law (EEG) of 2014 correspond to the stipulations of the EU Commission in its new Guidelines on State Aid for Environmental Protection and Energy, and their interpretation should therefore be strictly oriented to the latter. A point of concern in systematic respects is the participation of electricity self-producers in the EEG levy, because it violates the costs-by-cause principle. Irrespective of this issue, the exemption of old installations from this regulation is warranted for reasons of protection of legitimate expectation. For self-produced electricity from fossil-fuel-based cogeneration the EEG levy is to be reduced by 40%, following an agreement between the federal government and the EU Commission.

    In the current work we analyze formally selected problems in connection with the subsidisation of renewable energy in finance theoretical and industrial economic models. In the first part of the work we deal with the subsidisation of demonstration projects for testing new technologies in the field of renewable energy. The information about the economical performance of a technology, which is disclosed by first tests, is part of the value of such a demonstration project. We describe this value in a finance theoretical model as a real option. A reason for subsidising a demonstration project is given, when it is not exclusively the investor who benefits from the disclosed information. A technology may prove so efficient in a demonstration project that it will lead to a sustained decrease of the price for renewable energy. In this case the investment in a demonstration project has a positive externality in the form of a so -called consumer-surplus on consumers. This consumer surplus legitimises the subsidisation of demonstration projects. It also may be that other producers of renewable energy profit from a technology that is identical or at least similar to the technology - which is tested in a demonstration project. In this case the producers will benefit from the disclosed information since they can use it to estimate the performance of their own technologies. For this reason the investment in a demonstration project causes here a positive externality in form of an information spill-over to other producers with an identical or at least similar technology, which again legitimises the subsidisation. The second part of the current work contributes to answering the question how a good subsidising system to foster renewable energy should be designed. We therefore compare feed-in tariffs, quota obligations and bidding systems, all three common European subsidising schemes. We investigate which of the systems has the capacity to minimize on the one hand the profits of the

    In the research, it is argued that the targeted promotion of renewables leads to a change in the technological path dependency on the electricity market or led. The historically market depending portfolio of products in the conventional power industry will be replaced by an increasingly strong dependence on the product portfolio of Renewable Energy Sector according to this argumentation. The present work is devoted to the political explanation of the change and transition process in the electricity market. The process of policy formation in this market (especially support policies for renewable energies) will be discussed. It is examined from a public choice perspective, which political actors and instances in the past were responsible for the development and maintenance of individual policy elements. In particular, in this analysis the different private sector stakeholders in the electricity market move to center of attention. [German] In der Forschung wird argumentiert, dass die gezielte Foerderung der Erneuerbaren zu einer Veraenderung der technologischen Pfadabhaengigkeit am Strommarkt fuehrt bzw. gefuehrt hat. Die historisch bedingte Marktabhaengigkeit vom Angebotsportfolio der konventionellen Stromindustrie wird im Rahmen dieser Argumentation durch eine zunehmend starke Abhaengigkeit vom Angebotsportfolio des Erneuerbare-Eenergie-Bereichs ersetzt. Die vorliegende Arbeit widmet sich der politischen Erklaerung des Veraenderungs- bzw. Uebergangsprozesses am Strommarkt. Der Prozess der Politikbildung auf diesem Markt (v.a. der Foerderpolitik fuer erneuerbare Energien) wird diskutiert. Es wird aus einer Public-Choice-Perspektive untersucht, welche politischen Akteure und Instanzen in der Vergangenheit fuer die Entstehung und Aufrechterhaltung einzelner Politikelemente verantwortlich waren. Insbesondere ruecken bei dieser Betrachtung die unterschiedlichen privatwirtschaftlichen Interessengruppen am Strommarkt ins Zentrum der Aufmerksamkeit.

    The implementation of renewable energies to the electricity market is inefficient and expensive with current measures. Further these measures are prejudicial for the existing energy-only-market. The combination of fluctuating and controllable renewable powers in virtual power plants enables the marketing of this power as a derivate on the future market. Thus would relieve the spot market and stabilize pricing on both markets. Subsequently the renewable energy obligation will reduce and renewable energies could be marketed as secured power.

    The objective of the research project 'The world of renewable energies: Powerado' was to improve communication aimed at conveying renewable energies to children. In order to achieve his aim, materials for different age groups and multipliers have been developed. These helped determining successful strategies for communicating renewable energies. There were several reasons for the need of such a project. It may be the case that renewable energies have been included into the syllabus of primary schools, but they still have no prominent role at schools. Additionally, the training of multipliers for renewable energies shows severe deficits. The project consisted of ten interconnected modules which explicitly are described. Overall, the powerado project was a huge success. 58,000 estimated multipliers, children, adolescents and persons generally being interested in renewable energies have been reached by the project and its modules. So the powerado project achieved its main objective improving communication of renewable energies.

    The scarceness of fossil fuels as well as the greenhouse effect affect the economic, technological, social and political development world-wide. The use of renewable energies for the future power supply seems to be a solution. Under this aspect, the book under consideration gives a compact general view of the potentials and availability of the fossil fuels and the renewable energies. Scenarios are discussed in detail under economic and ecological criteria. The limits of the individual sources of energy (fossil, renewable, nuclear sources of energy) are discussed based on comprehensible, reliable sources. By means of simple example calculations and an extensive table statements can be understood.

    To reach significant CO{sub 2} emission reduction with electric vehicles, electricity production based on renewable energies is required. The aim of this study is to determine different options for linking the charging times of electric vehicles with fluctuating local renewable energy production. Energy demand profiles for electric cars were generated on the basis of statistic mobility data for Germany. The impact of different charging strategies for a high market penetration of electric vehicles is analyzed considering the renewable energy production and the distribution grid of the city of Freiburg. If all cars were substituted by electric vehicles, the electrical energy demand would increase by a third. Load peaks and the capacity usage of electric installations depend strongly on the amount of power and the simultaneity of the charging process. Decentralized electric vehicle charging based on tariff incentives is one option to influence the charging behavior. In the Freiburg area the residual grid load was adjusted by shifting the charging time to periods with high renewable energy production or low electric energy consumption. Another important aspect of this study is the development and realization of a pilot system for tariff incentive based load shifting. The so called ''mobile Dispatcher'' is principally used for the determination of the optimal charging strategy considering all relevant factors (e.g. user input data, time variable feed-in tariffs, energy consumption tariffs and battery degradation costs), the communication and data exchange with the charging station, as well as with the energy providers. Prior to the development of the ''mobile Dispatcher'', concepts to connect the electric vehicle to the grid were evaluated, and necessary modifications of the electricity marked structure were discussed. Based on the goals of the German national development plan, different grid integration strategies, such as mobile

    In 2003 Sweden became the first Scandinavian country to part with traditional promotion policies and instead stimulate electricity production from renewable resources by means of market incentives. On 1 January 2012 Sweden and Norway entered into a joint electricity certificate trading system, thus opening the door to Europe's first joint market for renewable energies. This has set the two countries on a good path towards securing for themselves a dominant position in the coming struggle for the long-term establishment of marketable renewable energies in the pan-European context.

    This study investigates current scenarios for a long-term transformation of the energy system towards high shares of renewable energy sources (RES) with a focus the associated costs. The scenarios include different regional scopes (Germany, Europe, and World) and were selected according to the following criteria: a minimum share of 80% RES electricity production in the power sector in 2050 and relevance in the public debate. Total transformation costs consist of a number of components, and scenarios are selective in terms of covered components as well as applied methodologies. For that reason total transformation costs are not comparable across scenarios. This can only be done for specific investment costs of RES technologies, which all scenarios rely on and treat in a consistent manner. Moreover, it can be assumed that specific investment costs are an essential driver of total transition costs. The essential mechanism for the development of future specific investment costs is the ''learning'' inherent to RES technologies. It is most widely used in the form of learning-by-doing, which assumes that specific investment costs decrease with increasing cumulated installed capacity. In fact, all investigated scenarios take account of learning-by-doing, by which the costs of all technologies are reduced until 2050. The largest reductions occur for solar energy (PV), which has abundant worldwide potential and a still relatively low degree of technological maturity. In contrast, the smallest reductions occur for wind energy (onshore), which is already mature and where expected technological progress is thus limited. Regarding capacity deployment, another relevant factor is the economic potential available in the respective region. They give rise to wind energy as the major technology in Germany, whereas solar energy dominates on the global level. For Europe the situation is more ambiguous, but solar energy is always an important option in case imports

    This final report for WWF Switzerland, Greenpeace Switzerland, the Swiss Energy Foundation SES, Pro Natura and the Swiss Cantons of Basel City and Geneva takes a look at the energy-relevant effects of the propositions made by Swiss electricity utilities for large-scale power generation. These proposals are compared with a strategy that proposes investments in energy-efficiency and the use of renewable sources of energy. The effects of both scenarios on the environment and the risks involved are discussed, as are the investments involved. The associated effects on the Swiss national economy are also discussed. For the efficiency and renewables scenario, two implementation variants are discussed: Inland investments and production are examined as are foreign production options and/or import from foreign countries. The methods used in the study are introduced and discussed. Investment and cost considerations, earnings and effects on employment are also reviewed. The report is completed with an extensive appendix which, amongst other things, includes potential reviews, cost estimates and a discussion on 'smart grids'

    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. However, this has been accompanied by soaring subsidies for renewable energies. One alternative to the current system of fixed prices for electricity fed into the grid would be a quota system with which various European countries have already gained experience. Such a system would make it possible to stiffen competition between the different technologies used for alternative power generation. Placing a relatively high burden on low-income households, the distributive effect of the subsidies associated with the Act should also be viewed critically. An alternative form of financing might serve to diminish such undesirable distribution effects. The latest amendment to the Act does not represent a fundamental reform of the subsidies. Though it includes significant improvements, it still lacks a realistic, reliable and clearly defined road map for ending subsidies altogether.

    The increased use of renewable energy sources is the stated goal of the German and European climate policy. According to the German government, in 2020, 35 % of electricity production will be covered by renewable energy (currently 20 %). To achieve this goal, the federal government has enacted the EEG. Currently, solid biomass plays an important role by having a share of 10 % of renewable electricity production while providing combined heat and power (CHP). Since the enactment of the EEG in 2000, the number, as well as the installed capacity of biomass (thermal) power plants (CHP) increased more than tenfold. During the first two versions of the EEG (EEG 2000 and EEG 2004) mainly larger (> MW{sub el}) and medium (> 500 MW{sub el}) sized biomass CHP-plants were installed. Later on (EEG 2009), progressively smaller biomass CHP-plants were built. This is due to the increasing scarcity of fuel wood as well as technological advances in power generation of small biomass CHP-plants - initially in the use of ORC turbines and most recently in the development of thermochemical gasifiers with a gas engine attached. In total, German CHP-plants using solid biomass produced 9 590 GWhel EEG relevant electricity in 2011. Therefore, more than 7.8 million tbone dry wood is used (except the fuel used in CHP-plants of the pulp and paper industry). It is expected, that the use of other types of biomass, such as straw, miscanthus and other energy crops will increase in the near future and mostly small, heat-operated biomass CHP-plants will be installed.

    The transfer or certain functions in a company which do not belong to the originary core of the business to specialists has becom a normal attitude in economy nowadays. Thus it is no longer something special to decide for outsourcing facturing, personnel, legal or IT service departments. Up to now, marketing was not included in such considerations, not in energy industry at least. The following article shows that this might change in the years to come and explains which advantages could be achieved by outsourcing marketing activities and transferring them to third parties.

    Subject of the interdisciplinary work are the following priorities: Discussion and results of the economic opportunities and risks as well as sociotechnological relationships in the use of a campus management system (CMS) under strong college complex organizational structures. Various stages in the life cycle of a software solution are affected. The main focus lies in the context of the underlying themes on the selection, integration and migration of CMS. In particular, the research results of a complex process model for the creation of an economic analysis to integrate CMS solutions form the major focus. Investigation of the status quo of external funding and its IT-based management at German universities. Characterization of the actual situation, development of science-based target concepts and derivation of possible implications and relevant recommendations for action for the organizational and process-oriented (re)design of IT support. Green Business (GB) as a global enterprise framework to increase sustainability in supply chains for the purposes of corporate governance. IT serves as an operative trigger to the strategic sustainability goals of companies. Fluctuations caused by renewable energy (RE), endanger the stability in the European energy network and lead to inefficient compensation and balancing power. In-depth investigations show two main approaches to increase network stability: producer-sided load management through active management of virtual power plants (VPP) based on neuro simulated forecasting methods under various use of real-time information (such as weather data) and prize-controlled, semiautomated use of energy on the demand-side. All these research activities have this in common: they underscore the relevance of information systems for effective organization- and workflow-design and the development of potentials as well as fundamental benefit effects.

    Only three years after the enactment of the 2009 amendment to the Renewable Energy Law (EEG) it has become necessary to publish this revised edition of the standard legal commentary on electricity feed-in from renewable energy sources. Taking effect on 1 January 2012 the Renewable Energy Law has once again been substantially amended. With its 85 articles and 5 annexes the law now contains many more normative rules than before. 19 single normative rules have been added, while more than half of those contained in the 2009 EEG have been revised, for some part extensively.

    The extension of emission control requirements during the last years lead to an increasing demand for blowers suited for the transport of explosive waste gas. Concerning hazardous explosive atmosphere which is classified as zone 1 or zone 2, the ``VDMA-Einheitsblaetter`` give guidance to appropriate constructional requirements for blowers. However, for zone 0-applications, there do not exist fixed construction requirements up til now. In the range of validity of the ``Verordnung fuer brennbare Fluessigkeiten - VbF`` a type approval is requested for blowers to be used for zone 0. Equipment intended for use in potentially explosive atmospheres will fall under the new Directive 94/9/EC (explosion protection directive) in future; equipment to be used for zone 0 will need an EC-type-examination certificate which shall be issued by a notified body in accordance to the Directive. (orig.) [Deutsch] Die zunehmende Erfassung von Anlagen durch emissionsrechtliche Anforderungen hat in den letzten Jahren zu einem immer groesseren Bedarf an Ventilatoren zur Foerderung von explosionsfaehiger Abluft gefuehrt.

    The platform 'system transformation' of the German Renewable Energy Federation (Berlin, Federal Republic of Germany) accompanies the forthcoming restructuring of the energy supply towards 100 percent renewable energy. The previous discussions of this platform provided two results: the fluctuating renewable energies must be placed at the center of considerations in order to enable a sustainable system design and market design. Furthermore, the question of how the fluctuating feed-in from renewable energy sources can be compensated has to be answered. Under this aspect, the contribution under consideration reports on these compensation options. There are different flexibility options available in order to create a safe, environmentally sustainable and affordable energy system.

    Energy sources such as coal, natural gas, petroleum, and nuclear fission have long been established on the marketplace and considered competitive. However, a comprehensive restructuring of energy generation is necessary, as conventional energy generation pollutes the environment. Therefore environmentally friendly energy sources, such as solar, wind or water power need to be promoted. However, regenerative energy sources are still not capable of competing with conventional energy. Marketability of renewable energy sources can only be achieved through government-sponsored promotion and regulation. Such measures include fixed price and fixed quantity models with green certificates. The support schemes for renewable energy sources are characterized by their wide-ranging adaptability. The various elements of a scheme must be adapted to a given country's set goals and specific circumstances. There is no universally applicable model. Based on given goals and opportunities, every domestic legislator faces the challenge of choosing the best scheme or developing a mixed model that combines various elements. The aim of this study is to provide a legal analysis of regulations concerning the support schemes for renewable energy sources within the framework of EU and international law. Furthermore, the study aimed at comparing support schemes implemented in Poland and Germany. In the EU, the electricity directive from 1996 and 2003, the directive on the promotion of electricity from renewable energy sources from 2003 and 2008, non-binding documents, such as the ''green and white book'', as well as the ''ALTENER'' program, successfully contributed to establishing the topic of renewable energies. Regarding international law, it is primarily the Kyoto protocol that has to be mentioned as a basis for the promotion of renewable energy sources. Poland introduced a fixed quantity model with green certificates. Separated reimbursements for

    The integration of an increasing amount of power generation from renewable energy sources is a large challenge for the electricity supply. Apart from the compensation of varying production by supra-regional grids and apart from the further development of peak load power stations the energy storage is discussed as an option. Several power suppliers referred to compressed air energy storage plants as a possible solution. The authors of the contribution under consideration compare the different concepts for compressed air energy power stations systematically. A special emphasis is the thermodynamic evaluation of the different concepts. Also energy-technical aspects are addressed which decide on possibilities of application and perspectives of development for compressed air energy power stations.

    Electrical heat pumps deliver energy for the heating of buildings whereby relatively ambient heat from soil, water or air is increased on a usable temperature level. In this case, electrical power is used. Electrical heat pumps do not only use renewable environmental energy, but also electricity from not-renewable sources of energy. An installation and a correct adjustment of a heat meter are recommended. The calculation of production costs should consider not only the operating cost, but also all resulting costs in a total cost calculation. Electrical heat pumps offer a high discharge of the environment, if electric power effectively is produced. In this case, electrical heat pumps can exceed also fuel cells.

    The German Energiewende has tongues wagging. Over discussions about electricity prices, feed-in-law and right-of-way for power lines, people sometimes forget the objectives: substantial reduction of carbon emissions and stabilization of the climate on a exologically and socially acceptable temperature level. Time and again doubts arise about ghe feasibility of such a system at reasonable cost in a densely populated industry nation of the northern hemisphere. The study discussed in this article demonstrates how the need for electricity and heat in Germany can be supplied by renewable energy to an extent of up to 100 %. Different scenarios will be shown which are in accordance with the 80 to 95 % reduction goal of the German government for the reduction of greenhouse gases. (orig.)

    Fundamentally, renewable energy plants increasingly can be no longer operated in a shielded niche. Rather, an integration of decentralized power plants in electricity networks and markets is required. The influencing and system integration of the demand side by means of energy efficiency and the load managment (Demand Side Management) increasingly is an important factor. The system integration requires technical and institutional adjustments. Technically, the connection of renewable energy plants to remote systems and their optimization locally becomes more important. The optimization of decentralized energy systems and the design of the system optimization by operators of power distribution systems have to be clarified. The effectiveness and efficiency of existing promotional instruments for renewable energy should be increased by means of activation of the energy industry's actors and the adaptation of the energy industry law.

    This study explains how the costs of electricity are an aggregate of different components. The electricity price paid by the end consumer contains not only the actual costs of energy production, which make up only about a third of the actual price in an average household, but also different surcharges such as network charges, electricity tax, value added tax and the concession levy. It furthermore contains the allocation charge stipulated by the Renewable Energy Law (EEG reallocation charge) as a means of allocating the costs of the subsidisation of electricity from renewable resources to the consumers. On the other hand conventional energy resources such as nuclear energy, hard coal and brown coal have substantially benefited over many decades from state subsidies in the form of financial aids, tax rebates and other promotive measures. The main difference between this and the subsidisation of renewable energy is that the costs of conventional energy resources are largely charged to the state budget rather than being made transparent in the electricity price. Based on an evaluation of the literature, data, interviews and the authors' own methodological deliberations this study makes a systematic comparison of the direct as well as indirect state subsidisation of renewable and conventional energy resources during the period from 1970 until 2012. The annual totals obtained for each energy resources are then set in relation to the share of that resource in overall electricity production, yielding specific subsidisation rates in terms of cents per kWh for each resource. This does not yet take into account the high consequential costs in the form of environmental damage and climate-related damage caused by fossil and nuclear fuels as well as the risks associated with the latter (collectively referred to as ''external costs''), all of which are charged to the polluters only at a small fraction of the true amount. The two cost categories of state

    Electrical power supply is mainly based on fossil and nuclear fuels. Their availability will be dramatically reduced within the next half century. The only possibility to maintain our high living and economic standard which is based on high energy consumption will be a reorganisation of our supplies towards renewable energies such as wind, photovoltaics and biomass. It is generally accepted that the maximum fraction of stochastically available renewable energies that can be integrated into our electricity supplies is 20 to 25 %. Reasons are stability of the electricity network and absence of possibilities to store large amounts of electricity. The author demonstrates that by integrating already existing intrinsic storage capacities on the demand side into the control of electricity supplies there is no longer an upper limit for integration of renewable energies. The following technologies on the demand side are taken into account: storage heating and electrical water heating, ventilation, refrigeration, circulation pumps and compressed air in industry. Furthermore, changes in user behaviour, compressed air energy storage, and transition to flexible electricity usage by integration of thermal storage are discussed. (orig.)

    The aim of this thesis is to investigate and assess future options, potentials, strengths and weaknesses of cogeneration of heat and power. This is carried out against the background of global climate change and the integration of an increasing share of fluctuating renewable energies in power generation considering the necessity of guaranteeing a reliable, efficient, sustainable and cost effective power supply. It is assumed that the transition process to an entirely renewable energy-based electricity generation in Germany will considerably depend on the integration of wind energy because of its economic competitiveness, environmental friendliness and potential. However, power generation using wind energy fluctuates quite considerably. Diesel motors are here investigated as a decentralized integration instrument. Thanks to their great flexibility, high efficiency and relatively low nominal capacity, they perfectly meet the requirements for the simultaneous decentralized use of heat. Boundary conditions of Diesel motor combined heat and power plants (CHP) are analyzed and described in this work, different models for wind energy integration are elaborated, and these models are used for several variations to simulate the balance of wind energy by cogeneration. In this context, environmental impacts are discussed. Common assessment methods on environmental impacts of CHP distort the results. The so-called output method is developed and described, by which the final assessment of environmental impacts is not implicitly mixed - as is commonly the case - with the calculation of environmental impacts. This output method is used to compare CHP generation with other energy conversion processes within the context of power generation including insulation of buildings, the use of different fuels and different applications for cogeneration. This work clearly demonstrates that while bio fuel resources can be optimally used for power generation, cogenerated electricity could also

    With the share of renewable energies within the electricity sector rising, improving their market integration (i.e. inclusion in the steering and remuneration processes of the electricity market) and system integration (i.e. enhanced responsibility for grid stability) is of increasing importance. To transform the energy system efficiently while ensuring security of supply, it is necessary to increase the alignment of renewable electricity production with short- and long-term market signals. The German Renewable Energy Sources Act 2012 introduced the market premium to provide market experience to renewable plant operators and incentives for demand-oriented electricity production. Shortly after its introduction, the instrument is already being criticised as ineffective and expensive. Building on early experiences, this article examines whether the market premium in its current design improves market and/or system integration, and if it seems suitable in principle to contribute to these aims (effectiveness). Also, potential efficiency gains and additional costs of ''administering integration'' are discussed (efficiency). While market integration in a strict sense (i.e. exposing renewables to price risks) is not the purpose of the market premium, it has successfully increased participation in direct marketing. However, windfall profits are high, and the benefits of gradually leading plant operators towards the market are questionable. Incentives for demand-oriented electricity production are established, but they prove insufficient particularly in the case of intermittent renewable energy sources. A continuation of the instrument in its current form therefore does not seem recommendable. To conclude, potential alternative solutions are presented.

    The costs of the promotion of solar power by the Renewable Energy Law (EEG) made the promotion to a prime example of a missed policy of subsidizing. On 11th October, 2010 the Wuppertal Institute for Climate, Environment and Energy (WI, Wuppertal, Federal Republic of Germany) submitted a study on behalf of the agency for renewable energies (Berlin, Federal Republic of Germany) concerning with the basic statements and cost estimations of the Rhenish-Westphalian Institute for Economic Research e.V. (RWI, Essen, Federal Republic of Germany) for the promotion of solar power. The contribution under consideration discusses nine points of criticism of the study of the WI. The economically justifiable difference in the cost estimation between WI and RWI amounts nearly 6 %. This deviation lies in the range of uncertainties. Differences going beyond this value are due to allegedly positive effects of the promotion of the photovoltaics. These are not considered cost-lowering by RWI. The order of magnitude of the costs of the German promotion of solar power, determined by the RWI, is confirmed by the study of WI.

    The threshold and developing countries reject most of the demands of the Kyoto Protocol and are waiting in suspense for the renegotiations on climate protection scheduled for December 2009 in Copenhagen. The American continent will play a decisive role here, not least because, in many experts' opinion, the United States have so far done too little in response to the imminent climate change. However, there is also a noteworthy example to the contrary, where, despite a difficult market environment, a political course is being pursued in accordance with sustainability principles and in reconciliation of economic, social and ecological goals: the example of Costa Rica. After having dedicated itself for decades to ecotourism this small Central American state has now set itself the honourable goal of establishing a CO{sub 2} neutral energy supply system by the year 2021. The intent of this book is to provide enterprises of the renewable energy sector with an overview of the Central American and in particular Costa Rican region and to offer advice as to when and for whom an entry into its local energy economy will be worthwhile and what should be taken into account in the process.

    The vision of E-Energy needs a secure, interoperable IT infrastructure as a base. The architectural development of smart grids is associated with domain-specific challenges and currently is at the beginning of the realization. The book under consideration compiles the basis for the architecture development. In addition to basic techniques as well as established process models of the 'enterprise architecture management' and the 'software engineering' existing contributions to the architecture of smart grid are discussed. Furthermore, an abstract reference architecture is described serving as a basis for the development of specific smart grid. Presumably, a smart grid integrates several IT infrastructures. IT attacks already are known. From this perspective, this book especially applies oneself to information security. Domain-specific standards such as the CIM standards and methods for testing standard compliance are described. Finally, some examples of implementation from the E-Energy project eTelligence are outlined for a smart grid architecture and highlights first best practices.

    This publication reports on how the steadily increasing costs caused by the Renewable Energy Law (EEG) have brought the German strategy for the expansion of renewable energies under criticism. According to theories of regulatory economic policy, which state that politico-economic incentives of this kind must necessarily result in an inefficient allocation of scarce resources, this cost increase can be interpreted as a direct consequence of the price intervention. The present publication takes a critical stance on this viewpoint, developing for its purpose a new position on regulatory policy referred to as the evolutionary cybernetic theory of economic policy. It starts out from the works of F.A. von Hayek, which it then takes a significant step further however. The author argues that price interventions can be meaningful strategies of economic policy as long as they are aimed at a temporary initiation of market development towards sustainability and efficiency. Based on this model conception of a shrewd pricing strategy the publication undertakes an analysis from the perspective of regulatory policy of the German subsidisation of renewable energies. In the process it not only reveals errors in design of the EEG but also makes a proposal for an amendment that could be effective in cutting through the present price dynamics. In presenting its recommendation of a self-steering expansion policy the publication not only contributes to the further development of an evolutionary cybernetic theory of economic policy but addresses the urgent problem of how to wisely use regulatory policy to create pricing strategies which serve the expansion of renewable energies.

    The present study forms the first part of an extensive project dedicated to an analysis of the cost and benefit effects of the continued development of renewable energies in the electricity and heat sectors. The project's objective is to establish a scientifically substantiated, generally accepted basis for a comprehensive assessment of the use and continued development of renewable energies up to the present. For this purpose the following report presents an overview and discussion of the approaches and methods used in the past for determining such effects. While some effects have already been quantified and discussed at length, others have largely been ignored or only considered in qualitative terms. The study particularly gives impetus to the analysis of cost and benefit effects in the heat sector, whereas in regard to the electricity sector it largely focuses on a thorough evaluation of studies already performed. All studies under review are categorised within a conceptual framework for the purpose of arriving at an overall assessment of effects without double counting or gaps. Effects are classified as follows, depending on the category in question: costs and benefits of renewable energy technologies; burdening of and relief to market participants; and effects on value creation and employment. Wherever possible, effects are quantified in monetary terms stating the object (e.g. electricity from renewable energy) and range of analysis in each case. The analysis horizon has initially been defined such that it captures the present situation (2007 and possibly 2008). The second part of the project covers follow-on or in-depth studies aimed at improving estimates and representations of current and future effects (in the years from 2020 to 2030).

    The increased use of renewable energy sources in place of fossil fuels is an important contribution to ecological energy supply. The energy research program of the federal government of the FRG which has been adopted a few weeks ago is sponsored with about 300 mio. DM annualy with a tendency to rise in the next four years and this emphasizes the importance the German government attaches to the research and development of this technology. This intense engagement - stronger developed as in all other European countries, comparable to the United States and Japan - is effected on the one hand in view of the use of these energy sources in the FRG, but on the other hand particularly with regard to the supply of the constantly increasing energy demand of the Third World and thus by taking the responsibility for the Third World.

    The German energy system is currently in a state of extensive transformation, which is primarily driven by the set of problems stemming from fossil energy sources and nuclear fuels being a finite resource and the largely unsolved problems arising from their use and the waste products and by-products that are generated through this use. An important goal of the pursued transformation of the German energy system, which has already been set in motion, is to reduce greenhouse gas emissions - in particular carbon dioxide, which is a by-product of the provision of the effective energies electricity and heat. Renewable energy sources and - in a transitional phase - decentralised fossil energy sources are to be used as alternatives to conventional fuels. But the question arises of the extent to which basic structural characteristics of the existing energy supply system should change: not only could the provision of electricity in Germany, which has been produced in large centralised power plants up to now, be decentralised, but also regulatory entities and the power marketplaces on which decentralised demand and supply are coordinated. This analysis examines - on the basis of a comprehensive description of the different system components on which the modelling of a specific distribution grid is based - the extent to which decentralisation of the German energy system can contribute to the reduction of CO{sub 2} emissions. To this end the dimensions of a possible decentralisation and their complex interactions are examined: - Basic framework conditions of policy and the energy industry for this decentralisation and the sub-markets of the electricity sector, which have already started to change, partly as a result of the increasing share of fluctuating production. In future the sub-markets are to play an important role in equalising fluctuating production; - Questions related to the integration of decentralised and renewable production, above all in terms of their integration

    Like hardly any other law, the Renewable Energy Sources Law (EEG) is a subject to continuing modifications. This makes the application of the already complicated regulations even for experts to a special challenge. With the proven Berliner comment EEG, now a reliable companion through the bureaucratic jungle is available. All regulations of the EEG are commented precisely and easily to understand by profound experts. An extensive selection of terminology enables a rapid orientation within this book. In addition to the excursions to renewable energy technologies, this book also describes the structural aspects in the establishment of a photovoltaic system.

    This report for the Swiss Federal Office of Energy (SFOE) deals with proposals for a remuneration system for heat obtained from renewable resources. Local and regional district heating systems cover around three percent of Swiss heating needs. The authors estimate that, if these systems were to be operated completely using renewable resources such as biomass, ambient heat and the renewable portion of heat from waste incineration, around seven per cent of needs could be met. Further, around 10,000 heating systems with a power of more than 350 kW could be operated with renewables. A further potential for the use of renewable heating resources can be found in wastewater treatment plants and industrial waste heat. Various obstacles and restraints on the use of renewable resources in the heating area are discussed. The idea of providing a cost-covering remuneration system for heat is discussed and compared with that for renewable electricity. The proposed system is discussed, which would provide investment subsidies, risk-coverage and project development subsidies. The report discusses the results of a market analysis and the differences to be found between the markets for electricity and heat. Existing promotional programs are noted and the aims of a possible remuneration system are discussed. A concept for a promotion program for renewable heat generation and the use of waste heat is introduced. The installations to be promoted and the amount of remuneration to be paid out are discussed. Finally, the costs and the effects of the proposed promotion scheme are discussed. A comprehensive appendix provides details on the proposed system and provides information on market volume, energy resources, networks and infrastructure, providers of heat energy, heat consumers and general conditions as far as factors such as pricing and legislation are concerned. Finally, the 'Climate Cent' foundation is commented on.

    The scientific evidence for the estimation of environmental costs was steadily improved in the recent years. The Federal Environment Agency (Dessau-Rosslau, Federal Republic of Germany) summarizes the scientific progress in this field by means of the methods convention. Environmental costs are macro-economically very important. Emissions of greenhouse gases, air pollutants and noise pollution, land use and the consumption of scarce resources result in high costs for health and environment. Estimates of environmental costs point out the negative impacts of a neglected environmental protection and substantiate the necessity to pursue the ambitious environmental targets. Environmental costs are also suitable for the assessment of measures and instruments of the environmental protection. Municipalities, businesses and households also can use estimates of environmental costs - especially for environment-related investment decisions.

    The transformation of the German energy system towards a significant reduction of energy-related CO{sub 2} emissions can be described by a sequence of different phases. Phase transitions result from individual structural requirements in the overall system under continuous further development of renewable energy converters, in particular solar and wind power. The upcoming second phase of transformation is characterized by a comprehensive system integration of volatile renewable energy in particular in the field of electricity supply. This requires both a flexible complementary production as well as the activation of flexibility options on the consumption side. The main drives for the reconstruction of the German energy system are the climate policy goals of the Federal Government. [German] Die Transformation des deutschen Energiesystems in Richtung signifikanter Reduktion energiebedingter CO{sub 2}Emissionen kann durch eine Abfolge verschiedener Phasen beschrieben werden. Phasenuebergaenge ergeben sich dabei aus strukturellen Erfordernissen im Gesamtsystem bei kontinuierlichem weiteren Ausbau erneuerbarer Energiewandler, insbesondere Sonne und Wind. Die anstehende zweite Phase der Transformation ist durch eine umfassende Systemintegration volatiler erneuerbarer Energien insbesondere im Bereich der Strombereitstellung gepraegt. Dies erfordert sowohl eine flexible komplementaere Erzeugung als auch die Aktivierung von Flexibilitaetsoptionen auf der Verbrauchsseite. Wesentlicher Antrieb fuer den Umbau des deutschen Energiesystems sind die klimapolitischen Ziele der Bundesregierung.

    The energy policy debate about renewable energies in Germany is currently focused almost exclusively on expansion targets of the power sector. Imost cases it remains an open question how much current is needed in the long term. A comparison of four cross-sectoral target scenarios shows that electricity consumption in 2050 in many cases could be much higher, depending on the assumptions and interpretation of climate targets than previously thought. [German] Die energiepolitische Diskussion um erneuerbare Energien in Deutschland konzentriert sich zurzeit fast ausschliesslich auf die Ausbauziele im Stromsektor.

    Der ökologisch nachhaltige, wirtschaftlich effiziente und politisch faire Umgang mit den Ressourcen der Erde ist eine der größten Herausforderungen an die Menschheit im 21. Jahrhundert und impliziert Paradigmenwechsel in allen Bereichen des gesellschaftlichen Lebens. Energie- und Verfahrenstechnik sind traditionell Bereiche, in denen der optimale Umgang mit kostbaren und beschränkt verfügbaren Ressourcen von erstrangiger Bedeutung ist. Zur Lösung der damit verbundenen komplexen Entscheidungsprobleme sind mathematische Methoden schon seit längerem im Einsatz. Hierbei können aber noch längst nicht alle bislang aufgetretenen Probleme fundiert angegangen werden. Der wachsende wirtschaftliche und ökologische Druck auf die Effizienz der Produktions-und Versorgungssysteme sowie stärkere Schwankungen von Angebot und Nachfrage führen zu neuen Herausforderungen, für die neue mathematische Methoden und Algorithmen entwickelt werden müssen.

    Electric power supply systems for coal mines in Germany from 2003 must adapt to developments in mining and to changing standards. Future systems should be more efficient, more compact, and with less network losses. Automatic network protection of underground networks of 5 kV and more is problematic due to economic considerations. Advantages are found in higher safety, protective earthing and faster information on disturbances. Economic considerations and formal boundary conditions concerning the acceptance of explosion protection systems and electrotechnical safety requirements permit only automation of existing switches with the aid of available protection systems. [German] Zur Realisierung einer elektrischen Energieversorgung im Steinkohlenbergbau in Deutschland fuer die Jahre bis 2003 und spaeter wird eine Anpassung an die bergtechnischen Entwicklungen notwendig. Zudem muss eine Anpassung an geaenderte Normenvorgaben erfolgen. In der Energieversorgung sind Entwicklungen im Gange, die Versorgung anders zu strukturieren, um den Abbaubetrieb leistungsfaehiger, kompakter und verlustaermer mit elektrischer Energie versorgen zu koennen. Die weitergehende Automatisierung des Netzschutzes ab 5 kV im Bereich unter Tage ist aufgrund der wirtschaftlichen Situation nur eingeschraenkt durchfuehrbar. Die moeglichen Sicherheitsvorteile liegen nach Auswertung bisheriger Forschungsvorhaben im Verhaeltnis von Ergebnis und Aufwand insbesondere: - im Erdschlussschutz der Hochspannungsnetze und - in der Stoerungsklaerung durch detaillierte Informationen des Netzschutzes. Die wirtschaftlichen Vorgaben und formalen Randbedingungen bei der Zulassung bezueglich Explosionsschutz und elektrotechnischer Sicherheitsanforderungen erlauben daher nur eine Automatisierung vorhandener Schalter durch Verwendung entsprechender vorhandener Schutzgeraete.

    This paper presents a set of artefactual field experiments on individual preferences and willingness to pay, respectively, for the consumption of green electricity. Based on an economic model of individual preferences for the provision of public goods, the design of our experiments involved different scenarios: subjects had to decide about their individual spending on green electricity as well as about the level of public subsidies for green electricity. Unlike hypothetical empirical methods, the experiments involved an incentive mechanism, i.e. subjects had to face the monetary consequences of their decisions. Our empirical results are distinct from those of other studies. It seems that the market potential of green electricity is overestimated at present. Hence, the market will not release the public in financing subsidies in this field. The conclusion can be drawn that individuals prefer binding collective contributions rather than individual market-driven activities. However, we contradict the standard explanation of political economy that such a kind of preference for regulatory instruments may be motivated by cost-illusion. Subjects were willing to bear far higher taxes as compared to the price mark-up they were willing to pay for green electricity offered by the market. (orig.)

    The main cause of global warming is the increased intensity of solar radiation. So a drastic reduction of carbon dioxide by human actions will not finish global warming. The CO2 concentration should be reduced by gentechnological methods e.g. a forced photosynthesis. Energy plays a role not only on earth but in the whole universe, so the conversion of energy into matter and back is written depthly and clearly by the aid of relativity theory and gravitation effects. What mankind will ever pollute the univers is able to balance and correct it. (GL) [German] Sind wir Menschen wirklich schuld an einer sich anbahnenden Erderwaermung und Klimakatastrophe?

Was sind rueckstandhaltige und rueckstandsfreie Energien? Durch dieses spannende Buch werden nicht nur diese Fragen ausfuehrlich beantwortet, sondern auch viele damit zusammenhaengende Probleme geloest. Lebensnahe Beispiele und ein einfacher Text machen die Thematik auch fuer das breite Publikum verstaendlich und zugaenglich. Im Rahmen einiger Theorien des Autors, der schon viele bahnbrechende Theorien entwickelt und mehrere Buecher veroeffentlicht hat, erfahren die Leser viele faszinierende Neuheiten.

    The growth of the renewable energies will not close the foreseeable energy gap with the conventional energy sources fast enough. Thus, the policy has to create still better incentives for investments in renewable energies, because the most important raw material of the renewable energies is money. The first two parts of this three-part contribution describe the shortage of fossil energy sources. We are now on the apex of the conventional power supply in the next ten to fifteen years. At the same time, the renewable energies only are at the beginning of their growth. The renewable energies only can close the gap between the rising energy consumption and sinking availability of fossil energy sources in time if the growth of the renewable energies is accelerated. In principle, the development of the renewable energy takes place in three phases: (a) Within the start-up phase with a relatively slow growth, the techniques are made suitable for mass production. The prerequisites for a fast growth are created; (b) Afterwards, a rapidly accelerating exponential growth with mass production follows; (c) After reaching a high market share, the development of the renewable energies passes into a saturation.

    Since 1988 the Land of Schleswig Holstein has been going new ways in its energy policy. Its declared aims are energy saving in heat and electricity supply, efficient energy utilisation, a greater utilisation of renewable energy resources, and, of principal importance, the phase-out of nuclear energy. As the legislative competence of the Laender is very restricted in matters relating to energy, the new policy has primarily been designed as a means of demonstrating by way of example that there actually are considerable potentials for saving energy and that they can be exploited. The present report gives an overview of the results of Schleswig Holstein`s energy policy of the last seven years. (orig./RHM) [Deutsch] Seit 1988 geht das Land Schleswig-Holstein energiepolitisch neue Wege. Das erklaerte Ziel: Energieeinsparung im Waerme- und Strombereich, rationelle Energieverwendung, staerkere Nutzung erneuerbarer Energien. Und grundsaetzlich: Ausstieg aus der Kernenergie. Da die Bundeslaender nur ueber eine sehr eingeschraenkte Gesetzgebungskompetenz im Energiebereich verfuegen, zielte die neue Energiepolitik zunaechst darauf ab, durch Foerderprogramme beispielhaft zu zeigen, dass tatsaechlich erhebliche Einsparpotentiale bestehen und auch umsetzbar sind. Der Bericht gibt einen Ueberblick ueber die Ergebnisse der Energiepolitik der letzten sieben Jahre in Schleswig-Holstein. (orig./RHM)

    Die Veränderung auf dem deutschen Energiemarkt durch die Energiewende bringt eine Viel-zahl von Problemen mit sich. Der stetig ansteigende Ausbau von erneuerbaren Energien und die daraus resultierende starke Schwankung der eingespeisten Energiemengen zwingen die Netzbetreiber zum Ausbau der Stromnetze [1]. Die dadurch verursachten Kosten lassen die Netznutzungsgebühren steigen, welche an die Endkunden weitergegeben werden. Ebenfalls stieg die EEG-Umlage (Erneuerbare-Energie-Gesetz) von 3,6ct/kWh im Jahr 2012 über 5,3ct/kWh im Jahr 2013 auf 6,3ct/kWh für das Jahr 2014 [2], [3], [4]. Die extrem schnell steigenden Energiekosten zwingen die Verbraucher zur Erhöhung ihrer Energieeffizienz, um die laufenden Kosten so niedrig wie möglich zu halten [3]. Dies verlangt nach innovativen Ansätzen und Lösungen im unternehmenseigenen Energiemanagement.

Sometimes, courageous people challenge the nature of things, helping us to get new insights and achieve a new viewpoint. The experience-oriented ''work in progress'' university is an adventure of this kind. The book looks into the Tesla laboratory and the Wardenclyffe Tower, both of which could not be completed for financial reasons, and addresses them from today's state of technology. The conceptional section is based on the ''Tesla doctrine'' which comprises fundamental philosophical statements on civilisatory progress. The book presents the results of the investigation.

    The discussion about the energy policy has so far been characterised by an unproductive either-or condition: Either the CO{sub 2} emission is reduced and the nuclear energy is extended or the use of nuclear energy is reduced and the CO{sub 2} emission continues to increase. This discussion has led to a delay of important reformation steps. The group Energy 2010 clearly proves in its study ``Future energy policy`` that CO{sub 2} reduction and the end of the use of nuclear energy can be combined. The strategy is as follows: consequent support of energy conservation (REN) and consequent support of the use of renewable energies (REG). This concept enables to overcome the national shortness of the energy policy: limited fossil energy resources, load of the atmosphere, increasing atomic pollution. The study suggests a 10-point-programme, amongst other the introduction of an energy tax, a subsidy programme for REN and REG and a balanced deregulation of the energy market, an extensive information and qualification programme. (UA) [Deutsch] Die bisherige energiepolitische Diskussion war durch ein unfruchtbares Entweder-Oder gekennzeichnet: Entweder wird CO{sub 2} reduziert und die Kernenergie ausgebaut, oder die Kernenergie wird abgebaut, dafuer nimmt aber der CO{sub 2}-Ausstoss weiter zu. Diese Konstellation hat zur Verzoegerung wichtiger Reformschritte gefuehrt. Die Gruppe Energie 2010 weist in ihrer Studie `Zukuenftige Energiepolitik` ueberzeugend nach, dass CO{sub 2}-Reduktion und Ausstieg aus der Kernenergie durchaus miteinander zu verbinden sind. Die Strategie lautet: Konsequente Foerderung von Energieeinsparung (REN) und ebenso konsequente Foerderung des Einsatzes erneuerbarer Energiequellen (REG). Nur auf der Grundlage eines solchen Konzeptes lassen sich die nationalen Engpaesse der Energiepolitik ueberwinden: Begrenzte fossile Energievorraete, Belastung der Atmosphaere, wachsende atomare Verseuchung.

    A sustainable supply of future generations with energy is not possible on the basis of fossil and nuclear energy sources. With the measures and technologies used, energy transition offers the opportunity to gradually reduce the use of these energy sources and to convert the energy supply system to the use of renewable energies. This chapter has shown that the departure from the existing system can contribute to a significant improvement in the health of the population. However, it is important parallel to the nationwide implementation of measures and technologies of the energy transition to ensure a continuous monitoring of possible health effects in order to be able to respond to potential risks at an early stage and to take adequate measures to reduce them. [German] Eine nachhaltige Versorgung zukuenftiger Generationen mit Energie ist auf Basis fossiler und nuklearer Energiequellen nicht moeglich. Die Energiewende bietet mit den eingesetzten Massnahmen und Technologien die Moeglichkeit, die Nutzung dieser Energiequellen sukzessiv abzubauen und das Energieversorgungssystem auf die Verwendung erneuerbarer Energien umzustellen. Das vorliegende Kapitel hat aufgezeigt, dass die Abkehr vom bestehenden System zu einer deutlichen Verbesserung der Bevoelkerungsgesundheit beitragen kann. Es ist jedoch wichtig, bei der flaechendeckenden Einfuehrung von Massnahmen und Technologien der Energiewende eine kontinuierliche Beobachtung moeglicher Effekte auf die Gesundheit sicherzustellen, um fruehzeitig auf potenzielle Risiken reagieren zu koennen und adaequate Massnahmen zu ihrer Reduktion zu ergreifen.

    For 2001, this study ascertained an electricity demand of 38 TWh for ICT end-use appliances in households and offices and their associated infrastructure. This corresponds to a share of almost 8% of the total electricity consumption of final consumption sectors in Germany (AGEB 2002). About 50% of the power demand are accounted for by household end-use appliances, a further 20% by office end-use appliances, the remaining 30% by the infrastructure required. A clear increase in the power demand by 45% up to 55.4 TWh is anticipated up to 2010 which is primarily caused by the increasing significance of ICT infrastructure. The stock of appliances and systems of ICT infrastructure will grow noticeably and since these devices, such as servers or mobile communications systems, are continuously operated, the consumption growth in normal mode is the strongest. The consumption in standby mode shows an increasing tendency, most notably up to the middle of the decade, whereas it decreases in off-mode. However, this has less to do with efforts for greater efficiency and more to do with the expected substitution of the off- by the standby mode (especially in televisions). (orig.) [German] Fuer das Jahr 2001 wurde in dieser Untersuchung ein den IuK-Endgeraeten in Haushalten und Bueros und der zugehoerigen Infrastruktur zuzurechnender Strombedarf in Hoehe von 38 TWh ermittelt. Dies entspricht einem Anteil von knapp 8% am gesamten Stromverbrauch der Endverbrauchssektoren in Deutschland (AGEB 2002). Rund 50% des Strombedarfs entfallen dabei auf die Haushalts-Endgeraete, weitere gut 20% auf die Buero-Endgeraete, die restlichen rund 30% auf die dafuer erforderliche Infrastruktur. Bis 2010 wird mit einem deutlichen Anstieg des Strombedarfs um 45% auf 55,4 TWh gerechnet, der vor allem durch die zunehmende Bedeutung der IuK-Infrastruktur verursacht wird. Da die meisten der im Bestand deutlich wachsenden Geraete und Anlagen der IuK-Infrastruktur wie Server oder Mobilfunkanlagen dauerhaft in Betrieb sind, faellt damit auch der Verbrauchszuwachs im Normalbetrieb am staerksten aus. Der Verbrauch im Bereitschaftsbetrieb zeigt vor allem bis Mitte des Jahrzehnts noch eine steigende Tendenz, waehrend er im Schein-Aus-Zustand ruecklaeufig ist. Dies ist allerdings weniger auf Effizienzanstrengungen als auf eine erwartete Substitution des Schein-Aus- durch den Bereitschaftsbetrieb (insbesondere bei Fernsehern) zurueckzufuehren. (orig.)

    Plant operators often do not have enough roof area of their own to install a PV plant. This often makes it necessary to conclude a contract with owners of suitable buildings for the leasehold of such areas. In the meantime municipalities have also started to make public buildings available for this purpose. This frequently leads to uncertainties as to the type of contract that arises when roof areas are leased for installation of PV plants coming into the purview of legal practice: Is it a tenancy contract or a lease contract? The present article therefore undertakes a detailed investigation of the civil law aspect involved in the surrender of roof areas for use by another.

    Power sharing between private households can bring about economic advantages and reduce the specific cost of power from renewable energy sources. An optimisation model is established for defining the optimum energy mix. The model was tested in a demonstration system in a solar village (Solar-Dorf Kettmannshausen e.V., Thuringia), which comprised two model households with two different heat generation systems by different producers with a common control and information system. The fundamental principles are generally applicable and can be applied to other systems, including hydrogen. (orig.) [German] Ein Energieaustausch zwischen privaten Haushalten kann oekonomische Vorteile erschliessen und damit die spezifischen Kosten von Nutzenergie aus erneuerbaren Energietraegern senken. Auf der Basis eines oekonomischen Kalkuels kann der optimale Energiemix aus Sicht eines privaten Haushalts in Form eines Optimierungsmodells abgebildet werden. Die Umsetzung der Modellierung auf eine vernetzte Demonstrationsanlage des Solar-Dorf Kettmannshausen e.V. in Thueringen erforderte die Entwicklung eines modular aufgebauten Regelungssystems, das zwei Modellhaushalte mit jeweils zwei verschiedenen Waermeerzeugungsanlagen unterschiedlicher Hersteller auf der Basis erneuerbarer Energien miteinander informationstechnisch vernetzt.

    The energy transition is stagnating and needs urgently new impulses. This could be obtained by regenerative gases. Years of experience and studies have shown that biomethane and other regenerative gases, as well as the power-to-gas technology in cooperation with a sector coupling which is a connection of the infrastructures of natural gas, electric power, heat and mobility, could be the missing link, and therefore the new driver of the energy transition. As only 24/7 available renewable energy source with expandable capacities, green gas thereby plays a key role. [German] Die Energiewende ist ins Stocken geraten und braucht dringend neue Impulse. Diese koennte sie durch regenerative Gase bekommen. Jahrelange Erfahrungen und Studien belegen, dass Biomethan und andere Regenerativgase sowie die Power-to-Gas-Technologie im Zusammenwirken mit einer Sektorkopplung, in der die Infrastrukturen von Gas, Strom, Waerme und Mobilitaet verbunden werden, das fehlende Glied und damit der neue Treiber der Energiewende sein koennten. Als einzige 24/7 verfuegbare erneuerbare Energiequelle mit ausbaufaehigen Kapazitaeten kommt Gruengas dabei eine Schluesselrolle zu.

    The Renewable Energy Sources Act (EEG) has so far been the driving force behind German energy transition and has found many imitators internationally as an effective funding instrument. With the reform of the EEG, which was approved by the Federal Government, the promotion of renewable energies (EE) was shifted from the current price to a quantity control. The present analysis of the impact of the switch to cost-efficiency, the diversity of actors, the achievement of the EE production targets and network consistency shows that the efficiency advantages of tendering may be reduced by higher transaction costs and regional expansion ambitions dampened. The tendered quantities are not sufficient for the long term to increase EE share to the targeted level. It is also doubtful whether a grid-compatible EE expansion is achieved. [German] Das Erneuerbare-Energien-Gesetz (EEG) war bislang der Motor der deutschen Energiewende und hat als effektives Foerderinstrument international viele Nachahmer gefunden. Mit der von der Bundesregierung beschlossenen Reform des EEG wird die Foerderung der erneuerbaren Energien (EE) von der bisherigen Preis- auf eine Mengensteuerung umgestellt. Die vorliegende Analyse der Auswirkungen der Umstellung auf Kosteneffizienz, Akteursvielfalt, Erreichen der EE-Erzeugungsziele und Netzkonformitaet zeigt, dass die Effizienzvorteile der Ausschreibungen ggf. durch hoehere Transaktionskosten verringert und regionale Ausbauambitionen gedaempft werden. Die ausgeschriebenen Mengen reichen langfristig nicht aus, um den EE-Anteil zielkonform zu erhoehen. Es ist zudem fraglich, ob ein netzkonformer EE-Ausbau erreicht wird.

    Many visionary action programmes are based on the conviction that hydrogen produced from renewable, environmentally sustainable resources is the chemical energy carrier of the future. In Hamburg there have been various pilot projects over the past ten years which deal explicitly with problems of infrastructure relating to the integration of renewable energy sources in the existing energy supply. One such example is the fuel cell block heating station in Hamburg Behrenfeld which has been supplying residential buildings for some time now. Another is a practice-oriented pilot project involving a hydrogen-fuelled PAFC with 220 kW thermal and 200 kW electrical power output. The hydrogen is supplied by a 60 m-3 LH{sub 2} tank, the first of its kind to be approved by the authorities and accepted by the public. [Deutsch] Viele visionaere Aktionsprogramme sehen aus dauerhaft umweltvertraeglichen Quellen erzeugten Wasserstoff als chemischen Energietraeger der Zukunft.

Ein Beispiel ist das in Hamburg-Behrenfeld seit einiger Zeit betriebene Brennstoffzellen-Blockheizkraftwerk zur Versorgung von Wohngebaeuden. Als praxisbezogenes Pilotprojekt wird u.a. eine H{sub 2}-versorgte PAFC mit 220 kW thermischer und 200 kW elektrischer Leistung betrieben.

    With the energy transition, the Federal Government has begun the conversion of the energy supply. Because of the success of the energy transition is essential for the future and competitiveness of Germany as a business location The Federal Association of German Industry (BDI) has already published 2013 Stimulus for a smart energy market, in which are derived five principles which provide a framework for discourse on the measures to be taken. Renewable energies will be the dominant source of electricity in the coming years. This results in new challenges. The Federal Ministry of Economics and Technology (BMWi) has recently adopted a 10-point agenda to address these issues (ZPA) for the central energy projects. To be discussed is to what extent they are in harmony with the five principles of the BDI and at which points adjustments are necessary, so that the conversion of the energy system can succeed. [German] Mit der Energiewende hat die Bundesregierung den Umbau der Energieversorgung begonnen.

    According to the motto of the energy transition the Federal Government set herself targets in the areas of greenhouse gas emissions, renewable energy and energy efficiency. Main emphasis of its climate change policy is the implementation of the 2014/15 Action Programme Climate Protection 2020. A key measure discussed here is the climate contribution of the German electricity sector, is now being implemented in a significantly modified form. With a view on the long-term climate objectives prepares the federal government the national climate change plan 2050; the federal government promote locally climate protection within the framework of the National Climate Protection Initiative (NKI) in a Variety of projects. On the level of the federal states intensifies clearly the trend of the legal protection of federal climate protection targets. In addition to the federal levels are also the municipalities still active in various climate protection projects.

    Within the framework of a project sponsored by the Stiftung Energieforschung Baden-Wuerttemberg, an axial turbine was developed as a flash evaporator, which permits energy recovery in all sectors where liquids in piping undergoes pressure relaxation. A specific feature of this turbine is that it forms part, complete with generator, of a single pipeline and that it does not cause any pressure variations worth mentioning in case of mains failure. The report describes the turbine, its advantages, and a pilot operation carried out with a prototype. The turbine`s performance is compared with a return pump. Further, the optimization of the hydraulic design by computer and the results of a market analysis are dealt with. (orig.)

    The Swiss Academy of Engineering Sciences has investigated the possibilities and the consequences of a consumption reduction by 50 % of fossil energy agents within a time frame of 20 to 40 years. A working group of the Academy has made a study on the subject of if and when it would be possible to reduce the consumption of fossil energy in Switzerland by 50 % compared to 1990. The working group came to the conclusion that a reduction of well over 40 % would be feasible by the year 2020, principally due to an improvement in efficiency. This takes into account the substitution potential by renewable energy alternatives. A reduction by 50% will be possible in the second quarter of the 21st century under the condition that both today's known technologies are indeed exploited and that energy prices are increased. For Switzerland's economy and society no unacceptable impacts will thereby result. (author) [German] Die Schweizerische Akademie der Technischen Wissenschaften (SATW) hat Moeglichkeiten und Konsequenzen eines um 50 % verringerten Verbrauchs an fossilen Energietraegern in der Schweiz in einem Zeitrahmen von 20-40 Jahren untersucht. Eine Arbeitsgruppe ihrer Kommission Energie unter dem Vorsitz von Hans Jucker (bis 1997 VR-Praesident der Alusuisse-Lonza Holding AG) kam zum Schluss, dass bis zum Jahre 2020 eine Reduktion um gut 40 % primaer durch Effizienzverbesserungen moeglich ist. Dabei ist das Substitutionspotential durch erneuerbare Energien beruecksichtigt. Eine Halbierung ist im Verlaufe des 2. Quartals des 21. Jahrhunderts erreichbar, wobei vorausgesetzt wird, dass die heute bekannten Technologien tatsaechlich genutzt werden und die Energie verteuert wird. Dabei werden f?r Wirtschaft und Gesellschaft keine unzumutbaren Auswirkungen erwartet.

    The rising complexity in production control requires an increasing demand on expert knowledge. By applying case-based reasoning the expert knowledge can be gathered in structural form and can be applied and adopted for future production control. The application of the combined approach of case-based reasoning and neural nets in production control appears to provide an added value. In special energy intensive sectors need new attempts, to fight against increasing cost by an energy efficient production. So shown on an example of the plastics industry in this report is shown, how an effective production control is possible taking into account the interactions between health damaging emissions and heat losses by ventilation. (GL) [German] Die Produktionsplanung und -steuerung ist vor allem durch logistikorientierte Zielgroessen gepraegt. Steigende Energiekosten durch Rohstoffverknappung, Reduzierung von Treibhausgasemissionen und die damit verbundene Umstellung auf erneuerbare Energien haben dazu gefuehrt, dass sich produzierende Unternehmen zunehmend in einem Spannungsfeld zwischen Energie und Klima befinden. Insbesondere energieintensive Branchen benoetigen neue Ansaetze, um durch eine energieeffizientere Produktion den steigenden Kosten zu begegnen. Am Beispiel der kunststoffverarbeitenden Industrie wird in der Arbeit dargestellt, wie durch die Beruecksichtigung der Wechselwirkungen zwischen gesundheitsschaedlichen Emissionen und Lueftungswaermeverlusten eine energieeffiziente Produktionssteuerung moeglich ist. An einem prototypisch entwickelten Simulationssystem, das neben den Materialfluessen auch die Stoff- und Energiefluesse innerhalb der Fabrik abbildet, werden insgesamt drei Ansaetze entwickelt und hinsichtlich ihrer Einsparpotentiale untersucht. Die Ergebnisse zeigen, dass eine Reduzierung des Heizenergiebedarfs von bis zu 26,5 % moeglich ist. Zudem eignen sich die vorgestellten Ansaetze einer energieeffizienten Produktionssteuerung auch zur Anpassung an

    After a long period of stability, the electricity industry is in the past 15 years, in a major state of flux. First, the switching of state-monitored and regulated regional monopolies to liberalized producer and consumer markets. At the moment we are in a similar change from conventional to renewable energy production. Below the main question will be addressed whether the paradigms of the individual phases are compatible, which still have their place and which should be modified. Moreover, it is shown that the current market design of the future cannot be designed on a blank sheet, but existing structures have to be considered. Given the stage of monopolies, the liberalization and the started energy turnaround respectively in terms of their sector structure, dominant generation technologies, the interaction between production and load and characteristic elements of market design and regulation are presented. Subsequently, a preliminary answer is given to the question raised. [German] Nach einer langen Phase der Stabilitaet ist die Stromwirtschaft in den vergangenen 15 Jahren stark in Bewegung geraten. Zunaechst stand der Wechsel von staatlich ueberwachten und regulierten Gebietsmonopolen hin zu liberalisierten Erzeuger und Verbrauchermaerkten an. Im Moment befinden wir uns in einem aehnlichen Umbruch, weg von konventioneller hin zu erneuerbarer Energieerzeugung. Im Folgenden soll der Leitfrage nachgegangen werden, ob die Paradigmen der einzelnen Phasen miteinander vereinbar sind, welche noch immer ihre Daseinsberechtigung haben und welche modifiziert werden sollten. Darueber hinaus wird gezeigt, dass das Strommarktdesign der Zukunft nicht auf einem leeren Blatt entworfen werden kann, sondern bestehende Strukturen zu beruecksichtigen sind. Dazu werden die Phase der Monopolwirtschaft, der Liberalisierung sowie der begonnenen Energiewende jeweils hinsichtlich ihrer Sektor Struktur, dominierenden Erzeugungstechnologien, des Zusammenspiels zwischen Erzeugung und Last

    The global problems of exhaustion of fossil fuel and climate change become serious.And thus,aiming at sustainable development,to explore and use renewable energy are the current energy policies around the world;and most of them are in way of legislation.In general,many countries legislate for energy,and execute with concrete,accurate,compulsive regulation or economic encouragement.The law concerning renewable energy of Germany is a remarkable example.In 2000,German Government passed the first law concerning renewable energy in the world and named it Law for the Procedure of Renewable Energy(Gesetz für den Vorrang Erneuerbarer Energien).Renewable Energy Law(Ernererbare-Energien-Gesetz,EEG) in short.It has been revised many times so far.This article will cut in from the EEG and observe the core of the law,which is called Feed-in Tariff(FIT) and the direction of legislative revision in current years to discuss the background and current situation of the development of renewable energy industry in Germany.%全球传统石化能源耗竭及气候变迁等负面效应日益严重,以永续发展为目标,再生能源之开发利用备受关注,已成为世界各国能源政策的主要施政方针,其中多以立法手段积极推动.综观各国已提出亦或正在施行的政策和措施,皆由订定法令来体现,以法律的形式确立发展目标,再透过具体而明确的强制规范或经济激励措施,进而得其实质成效.德国再生能源法相关法规范即为明证.德国于2000年制定全球首部再生能源优先法(Gesetz fürden Vorrang Erneuerbarer Energien),简称再生能源法(Ernererbare-Energien-Gesetz,EEG),至今已历多次修法.本文将从德国再生能源法制探讨,观其核心固定电价制度(Feed-in Tariff,FIT)与近年修法方向,说明德国再生能源产业发展之背景及现况,希祈能就推动发展再生能源有所帮助.

    The share of renewable electricity generation of gross electricity consumption in Germany increased from 6.8 % to about 20 % during the years of 2000 and 2011. This share will increase even more in the future. The greater part of the renewable electricity generation is characterized by significant fluctuations, which can only be planned to a limited extent. Hence, the electricity system in Germany faces the challenge to integrate an increasing amount of fluctuating renewable electricity generation. Additionally the system stability needs to be ensured, despite a decreasing capacity in conventional power plants. One option to support the integration of large amounts of renewable electricity generation and to enhance system stability is the deployment of storage technologies. The aim of this research was to analyze the role of storage technologies to integrate high shares of renewable electricity generation into the electricity system of Germany. To achieve this aim, adiabatic compressed air energy storage, diabatic compressed air energy storage and mobile battery storage systems were simulated and compared with a pumped hydro storage as the reference storage system. Key characteristics of these storage systems were modeled within a fundamental stochastic unit commitment model of the German power markets (Joint-Market-Model) in order to analyze the effect of the implementation of these storage systems on the overall cost of the electricity system. Additionally, the operation of the storages in an electricity system with high shares of renewable energy was evaluated. The results show that the integration of large shares of renewable electricity generation into the grid can only be achieved with a substantial implementation of storage systems. To integrate 50 % of renewable energy, a storage power of 27 GW and storage capacity of 245 GWh is needed. For a renewable energy share of 80 %, a storage power of 78 GW and a storage capacity of 6.3 TWh are necessary. A 100

    2012-07-01

    This paper examines the local impacts of renewable energy carrier promotion by the German feed-in tariffs scheme ''Erneuerbare-Energien-Gesetz'' for the German State of Baden-Wuerttemberg by using an input-output approach. The local impacts are of particular interest as in Baden-Wuerttemberg the manufacturing industries are highly important compared to the rest of Germany. We analyze the effects of the policy actions on the production as well as the employment of several sectors. We construct a regional input-output table of Baden- Wuerttemberg and introduce the construction and the operation of installations for seven renewable energy types in order to examine different paths to achieve the state government's targets. We consider two scenarios with different sources funding the investments in the construction and operation of renewable energy installations. In the first scenario, all the necessary investments are funded completely by internal sources. Hence, the scenario is driven by the assumption that these investments either crowd out investments in other industries of the regional economy or the investments are paid by the government, i.e. by taxes which are borne by all other industries and by the households. Therefore, the final demand of all other sectors decreases. In this scenario, we have a slightly positive total turnover effect, although in many sectors the turnover effect is negative. In addition, the total employment effect is negative since the more labour-intensive industries are affected more heavily from the policy than the less labour-intensive industries. The second scenario considers the case of a partly external funding by taking into account that the installations may be demanded from ''abroad'', i.e. the rest of Germany and the rest of the world. Therefore, investments in other industries are not completely crowded out in this scenario. We find positive production and employment effects also for

    .132 Petajoule den niedrigsten Stand seit 1990. Die erneuerbaren Energien sind Deutschlands wichtigste Stromquelle. Der Anteil erneuerbarer Energie am Stromverbrauch lag im ersten Halbjahr 2015 erstmals ueber 30 Prozent. Beim Ausbau der erneuerbaren Energien im Stromsektor liegt Deutschland auf Zielkurs. Die Hoehe der EEG-Umlage hat sich stabilisiert. Die durchschnittliche Steigerung der Energieeffizienz zwischen 2008 und 2014 lag mit 1,6 Prozent unter dem im Energiekonzept der Bundesregierung vorgesehenen Wert von 2,1 Prozent. Hier besteht weiterer Handlungsbedarf. Die Bundesregierung hat darum mit dem am 3. Dezember 2014 beschlossenen Nationalen Aktionsplan Energieeffizienz die Anstrengungen zur Effizienzsteigerung gebuendelt und verstaerkt. Der Endenergieverbrauch im Verkehr war 2014 rund 1,7 Prozent hoeher als 2005. Um das Ziel einer Senkung des Endenergieverbrauchs um 10 Prozent gegenueber 2005 zu erreichen, sind weitere Anstrengungen erforderlich. Zum ersten Mal seit ueber zehn Jahren sanken zu Beginn des Jahres 2015 die Strompreise fuer Haushaltskunden. Fuer Industrie- und Gewerbekunden, die nicht unter Entlastungsregelungen fallen, sind die Strompreise im Jahr 2014 nahezu konstant geblieben. Der Boersenstrompreis ist 2014 um weitere 10 Prozent zurueckgegangen und auch in 2015 weiter gefallen. Im Jahr 2014 hat Deutschland fossile Energietraeger im Wert von rund 81 Milliarden Euro eingefuehrt. 2013 waren es noch rund 95 Milliarden Euro. Zu den gesunkenen Importausgaben haben vor allem niedrigere Rohstoffpreise, aber auch geringere Importmengen beigetragen.

    The exit of the use of nuclear energy in Germany, it was decided in the summer of 2011 in a rush. Now it is becoming obvious that there is no realistic plan for the conversion of energy supply in the envisaged deadline of ten years. For the conversion of our entire power supply and therefore our economy the period is too short. It lacks a robust empirical reason that have to deal with the issues of security of supply, the affordability, the impact on economic development and social justice. Thus, this treansition threatens to fail at their contradictions. Konrad Kleinknecht tries in his book, to name the problems and to find answers. For him, arise the following questions: What are our opportunity to replace with wind and solar power to replace a part of the power supply? What power sources provide secured capacity? Can we dispense with coal-fired plants? Do we need new power lines? How power may be stored? How real is the risk of blackouts in windless nights? Will the power prices continue to rise? Can be avoided the major risks of the energy transition with a fundamental reform of the Renewable Energies Act (EEG)? The power supply must serve the common good and benefit the industrial site Germany. A blackout would be a disaster for the whole country, it must be avoided at all events. How can we manage this, the author present in his evocative book. [German] Der Ausstieg aus der Nutzung der Kernenergie in Deutschland wurde im Sommer 2011 im Eiltempo beschlossen.

    Increased focus has been placed on the issues of energy access and energy poverty over the last number of years, most notably indicated by the United Nations (UN) declaring 2012 as the 'International Year of Sustainable Energy for All'. Although attention in these topics has increased, incorrect assumptions and misunderstandings still arise in both the literature and dialogues. Access to energy does not only include electricity, does not only include cook stoves, but must include access to all types of energy that form the overall energy system. This paper chooses to examine this energy system using a typology that breaks it into 3 primary energy subsystems: heat energy, electricity and transportation. Describing the global energy system using these three subsystems provides a way to articulate the differences and similarities for each system's required investments needs by the private and public sectors.

    Energy sources and energy consumption in India are discussed. Human and animal power constitute the principal sources of energy; both are extremely efficient users of the energy in food if they get enough; the food itself takes little energy to grow if energy-intensive agriculture does not take over from traditional methods. Of the commercial sources of energy with which India is endowed, the scarcest are natural gas and petroleum; the most abundant and reasonably well distributed geographically, except for the metallurgical grade, is coal; the one which holds out the greatest promise for the future is nuclear energy. The most important aspect of the energy problem in India is the short supply of coal to steel plants, electric utilities, and such vital industries as cement and textiles. There is a stark confession of the absence of progress on the energy front during the past 18 years. (MCW)

    Energy resources, the basic input in every area of the economy, have a fundamental function for society's welfare. Traditional energy resources are, however, rapidly decreasing. Energy supply has been falling behind in meeting global demand, and is causing increased focus on efficiency and economy concepts in recent energy policies. Since the existing energy resources are not spread evenly among the countries, but instead are concentrated in certain regions and countries, a monopolistic situation arises. Equally, supply assurance is an issue, since the energy supply is held by certain regions and countries who have monopolistic pricing power. Both the EU and many other countries are studying how to marketize energy. This book focuses on the importance of energy and the problems posed by it. It will be useful for the academic community, related sectors and decision makers.

    Solar energy is the most abundant energy resource on earth. In a sustainable future with an ever-increasing demand for energy, we will need to use this resource better. Solar energy technologies either convert sunlight directly into heat and electrical energy or use it to power chemical conversions which create 'solar fuels' or synthetic compounds. Solar heating technologies have developed steadily for many years and solar heating and cooling is one of the world's commonest renewable energy technologies. This chapter, however, focuses on technologies for electricity production and touches more briefly on the prospects for solar fuels. The section on Danish perspectives also discusses solar thermal heating in district heating plants. In recent decades, two technologies for converting solar energy into electrical energy have dominated: photovoltaics (PV) and concentrating solar power (CSP). Today's silicon and thin-film PV technologies are advancing steadily, with new materials and technologies constantly being developed, and there are clear roadmaps for lowering production costs. In the discussion below we assess the maturation potential of currently emerging PV technologies within the next 40 years. Concentrating solar power is already a proven technology, and below we evaluate its potential to become a substantial part of the energy mix by 2050. Solar fuels cover a range of technologies. The chapter is to a great extent based on two recent roadmaps from the International Energy Agency (IEA). Many reports, predictions, scenarios and roadmaps for solar energy deployment exist. The IEA predictions for the penetration of solar energy in the future energy system are low relative to many of the other studies. The IEA roadmaps, however, cover most aspects of the future deployment of the technologies and reference older work. (Author)

    From its rebirth in the early 1980s, the rate of development of wind energy has been dramatic. Today, other than hydropower, it is the most important of the renewable sources of power. The UK Government and the EU Commission have adopted targets for renewable energy generation of 10 and 12% of consumption, respectively. Much of this, by necessity, must be met by wind energy. The US Department of Energy has set a goal of 6% of electricity supply from wind energy by 2020. For this potential to be fully realized, several aspects, related to public acceptance, and technical issues, related to the expected increase in penetration on the electricity network and the current drive towards larger wind turbines, need to be resolved. Nevertheless, these challenges will be met and wind energy will, very likely, become increasingly important over the next two decades. An overview of the technology is presented.

    Nuclear energy can play a role in carbon free production of electrical energy, thus making it interesting for tomorrow's energy mix. However, several issues have to be addressed. In fission technology, the design of so-called fourth generation reactors show great promise, in particular in addressing materials efficiency and safety issues. If successfully developed, such reactors may have an important and sustainable part in future energy production. Working fusion reactors may be even more materials efficient and environmental friendly, but also need more development and research. The roadmap for development of fourth generation fission and fusion reactors, therefore, asks for attention and research in these fields must be strengthened.

    Wind energy is a variable and uncertain renewable resource that has long been used to produce mechanical work, and has developed into a large producer of global electricity needs. As renewable sources of energy and feedstocks become more important globally to produce sustainable products, many different processes have started adopting wind power as an energy source. Many times this is through a conversion to hydrogen through electrolysis that allows for a more continuous process input. Other important pathways include methanol and ammonia. As the demand for sustainable products and production pathways increases, and wind power capital costs decrease, the role of wind power in chemical and energy production seems poised to increase significantly.

    Modern steam generators have maximum gas temperatures at the combustion chamber outlet for maximum efficiency. The temperature is limited by the material characteristics of the downstream elements and by the softening temperature of the ash particles. Soiling and slagging in these parts will interfere with the operating process and reduce the availability of a plant. To define a so-called 'safety distance' between the particle temperature and critical softening temperature, knowledge is required of the local temperature distribution, the particle parameters, and the mineralogical properties of the ash particles. Systematic, complex investigations comprising CFD simulations, model and original measurements and thermochemical calculations were carried out for the purpose of solving this problem. [German] Der Wirkungsgrad moderner Anlagen wird unter anderem durch eine moeglichst hohe Gastemperatur am Feuerraumende gesteigert. Eine Limitierung der Temperatur erfolgt durch die Materialeigenschaften der nachgeschalteten Elemente und durch die Erweichungstemperatur der Ascheteilchen.

    Efficiency and sustainability have become key issues in the attempt to attain global climate protection goals. A project is presented in which an existing block of office buildings was optimized energetically with the intention of reducing climate-relevant emissions. The administrative center at Duisburg comprises 11 buildings that are used as offices, training centre, lecture hall and canteen. There is also a computer center. Energy sources are electricity, natural gas, and heating oil. Cold is generated in four central stations for air conditioning purposes. In the first step, the energy consumption of the buildings was analyzed in detail. The whole complex was evaluated by a complex simulation model in order to identify the energy consumption structure and to quantify measures taken in consideration of all relevant interdependences. The focus was on room air conditioning as this is a factor that can easily be influenced and accounts for much of the total energy demand of a building. The simulation model was validated using real measurements, and a consistent energy flow chart was established. After this, sensitivity analyses were carried out in order to identify and evaluate the available energy conservation potentials. Measures for better room air quality control were identified and implemented, resulting in considerable savings in terms of electricity consumption, cold generation, and natural gas consumption. Most of the measures were control measures that required only low investments, and a payback period of about one year was achieved. The measures were validated by energy controlling. It was found that C=2 emissions were reduced by 27 percent. The customer achieved added value on a long-term basis.

Geothermal energy is the thermal energy stored in the underground, including any contained fluid, which is available for extraction and conversion into energy products. Electricity generation, which nowadays produces 73.7 TWh (12.7 GW of capacity worldwide, usually requires geothermal resources temperatures of over 100 °C. For heating, geothermal resources spanning a wider range of temperatures can be used in applications such as space and district heating (and cooling, with proper technology, spa and swimming pool heating, greenhouse and soil heating, aquaculture pond heating, industrial process heating and snow melting. Produced geothermal heat in the world accounts to 164.6 TWh, with a capacity of 70.9 GW. Geothermal technology, which has focused for decades on extracting naturally heated steam or hot water from natural hydrothermal reservoirs, is developing to more advanced techniques to exploit the heat also where underground fluids are scarce and to use the Earth as a potential energy battery, by storing heat. The success of the research will enable energy recovery and utilization from a much larger fraction of the accessible thermal energy in the Earth’s crust.

The success of the research will enable energy recovery and utilization from a much larger fraction of the accessible thermal energy in the Earth's crust.

    Full Text Available Biomass fuels account for nearly 14% of the world’s energy. Energy forestry has been investigated since the mid-1960s to produce fiber for the paper and pulp industry. In the 1970s, following the oil crises, the emphasis switched to producing woody biomass for energy using fast-growing trees. Fastgrowing broadleaved trees, such as poplars and willows are grown at close spacing and under intensive management systems more akin to agriculture practice than forestry. In Turkey, rehabilitation studies in especially oak coppice stands are thought to be a part of the energy forestry, but the areas coppice stands grow on and species common in those areas are not suitable for modern energy forestry used in developed countries.

    Energy storage technology is critical if the U.S. is to achieve more than 25% penetration of renewable electrical energy, given the intermittency of wind and solar. Energy density is a critical parameter in the economic viability of any energy storage system with liquid fuels being 10 to 100 times better than batteries. However, the economical conversion of electricity to fuel still presents significant technical challenges. This project addressed these challenges by focusing on a specific approach: efficient processes to convert electricity, water and nitrogen to ammonia. Ammonia has many attributes that make it the ideal energy storage compound. The feed stocks are plentiful, ammonia is easily liquefied and routinely stored in large volumes in cheap containers, and it has exceptional energy density for grid scale electrical energy storage. Ammonia can be oxidized efficiently in fuel cells or advanced Carnot cycle engines yielding water and nitrogen as end products. Because of the high energy density and low reactivity of ammonia, the capital cost for grid storage will be lower than any other storage application. This project developed the theoretical foundations of N2 catalysis on specific catalysts and provided for the first time experimental evidence for activation of Mo 2N based catalysts. Theory also revealed that the N atom adsorbed in the bridging position between two metal atoms is the critical step for catalysis. Simple electrochemical ammonia production reactors were designed and built in this project using two novel electrolyte systems. The first one demonstrated the use of ionic liquid electrolytes at room temperature and the second the use of pyrophosphate based electrolytes at intermediate temperatures (200 – 300 ºC). The mechanism of high proton conduction in the pyrophosphate materials was found to be associated with a polyphosphate second phase contrary to literature claims and ammonia production rates as high as 5X 10

    The objective of the Symposium for Public Awareness on Energy was to provide an information exchange among the members of the technical community and the public, civic, fraternal, service, and labor organizations on timely energy-related issues. The 1977 symposium was oriented toward state and local governmental officials in the southeastern states. Since it is these officials who have the responsibility for the development and actualization of local energy strategies, the program was directed toward providing information which would be of help to them in considering energy plans. The symposium presentations featured speakers who are recognized in many facets of the energy field. A variety of views were expressed and a number of policy alternatives were suggested. It is hoped that the presentations provided the motivation for the audience to return to their respective communities with a new and expanded perspective regarding energy issues and policies. The private and public organizations represented at the symposium can continue to provide pertinent information to those who are interested. A separate abstract was prepared for each of the 9 presentations.

    Dark energy is one of the mysteries of modern science. It is unlike any known form of matter or energy and has been detected so far only by its gravitational effect of repulsion. Owing to its effects being discernible only at very very large distance scales, dark energy was only detected at the turn of the last century when technology had advanced enough to observe a greater part of the universe in finer detail. The aim of the report is to gain a better understanding of the mysterious dark energy. To this end, both theoretical methods and observational evidence are studied. Three lines of evidence, namely , the redshift data of type Ia supernovae, estimates of the age of the universe by various methods, and the anisotropies in the cosmic background radiation, build the case for existence of dark energy. The supernova data indicate that the expansion of the universe is accelerating. The ages of the oldest star clusters in the universe indicate that the universe is older than previously thought to be.

The material is presented at a low technical level with emphasis on general principles, which are not difficult to understand, rather than technology. The entries vary in length from a few lines to several pages, according to circumstances. As a general rule, each topic is defined and outlined in the first paragraph; this may be followed by a more detailed treatment, as required. An important feature of the Deskbook is the use of boldface (heavy) type for cross references. Words in the text set in boldface are the titles of articles where the particular subjects are described.

    2007-01-01

    An overview is presented of a recently proposed "radically conservative" solution to the problem of dark energy in cosmology. The proposal yields a model universe which appears to be quantitatively viable, in terms of its fit to supernovae luminosity distances, the angular scale of the sound horizon in the cosmic microwave background (CMB) anisotropy spectrum, and the baryon acoustic oscillation scale. It may simultaneously resolve key anomalies relating to primordial lithium abundances, CMB ellipticity, the expansion age of the universe and the Hubble bubble feature. The model uses only general relativity, and matter obeying the strong energy condition, but revisits operational issues in interpreting average measurements in our presently inhomogeneous universe, from first principles. The present overview examines both the foundational issues concerning the definition of gravitational energy in a dynamically expanding space, the quantitative predictions of the new model and its best-fit cosmological parameter...

    The United States and other countries face the problem of waste disposal in an economical, environmentally safe manner. A widely applied solution adopted by Americans is "waste to energy," incinerating the refuse and using the steam produced by trash burning to drive an electricity producing generator. NASA's computer program PRESTO II, (Performance of Regenerative Superheated Steam Turbine Cycles), provides power engineering companies, including Blount Energy Resources Corporation of Alabama, with the ability to model such features as process steam extraction, induction and feedwater heating by external sources, peaking and high back pressure. Expansion line efficiency, exhaust loss, leakage, mechanical losses and generator losses are used to calculate the cycle heat rate. The generator output program is sufficiently precise that it can be used to verify performance quoted in turbine generator supplier's proposals.

    Deviations in Q for resonant superconducting radio frequency niobium accelerator cavities are generally correlated with resistivity loss mechanisms. Field dependent Qs are not well modeled by these classical loss mechanisms, but rather can represent a form of precision cavity surface thermometry. When the field dependent Q variation shows improvement with increasing B field level the classical treatment of this problem is inadequate. To justify this behavior hydrogen as a ubiquitous impurity in niobium, which creates measurable property changes, even at very low concentrations is typically considered the cause of such anomalous behavior. This maybe the case in some instances, but more importantly any system operating with a highly coherent field with a significant time dependent magnetic component at near 2° K will have the ability to organize the remaining free spins within the London penetration depth to form a coupled energy reservoir in the form of low mass spin waves. The niobium resonant cavities are composed of a single isotope with a large nuclear spin. When the other loss mechanisms are stripped away this may be the gain medium activated by the low level residual magnetic fields. It was found that one resonant cavity heat treatment produced optimum surface properties and then functioned as a MASER extracting energy from the 2° K thermal bath while cooling the cavity walls. The cavity operating in this mode is a simulator of what can take place in the wider but not colder universe using the cosmic microwave background (CMB) as a thermal source. The low mass, long lifetimes, and the scale of the magnetic spin waves on the weakly magnetized interstellar medium allows energy to be stored that is many orders of magnitude colder than the cosmic microwave background. A linear accelerator cavity becomes a tool to explore the properties of the long wave length magnetic spin waves that populate this cold low energy regime.

    Nuclear power has long been controversial, especially in Europe, with concerns over the safety of nuclear installations, radioactive waste, and proliferation of nuclear weapon materials. Globally, however, renewed interest in nuclear energy has been sparked by concerns for energy security, economic development, and commitment to reduce CO{sub 2} emissions. Nuclear fission is a major source of energy that is free from CO{sub 2} emissions. It provides 15 % of the world's electricity and 7 % of total primary energy consumption. Around 440 nuclear reactors are currently generating power in 31 countries, with largest capacity in Europe, the USA and Southeast Asia. Non-electricity applications are few at present, but include process heat, hydrogen production, ship propulsion, and desalination. Nuclear power is characterised by high construction costs and a relatively long construction period, but low operating and maintenance expenses, including fuel. Most nuclear power plants in the USA and Europe have second-generation light water reactors (LWRs), while the plants now being built in Southeast Asia are of third-generation design. The Evolutionary Power Reactor (EPR) under construction in Finland, and the Pebble Bed Modular Reactor (PBMR) being developed in South Africa, are both of types referred to as Generation III+. From 2020-30 onwards fourth-generation reactors are expected to provide improved fuel utilisation and economics. Nuclear power does not form part of the Danish energy mix and at present there seems to be little political will to change this position. As a result Denmark has relatively little expertise in nuclear power. However, since nuclear power provides a substantial share of Europe's electricity, Denmark should ensure that it has expertise to advise the government and the public on nuclear issues. (BA)

  1. Photovoltaic energy

    Science.gov (United States)

    1990-01-01

    In 1989, the U.S. photovoltaic industry enjoyed a growth rate of 30 percent in sales for the second year in a row. This sends a message that the way we think about electricity is changing. Instead of big energy projects that perpetuate environmental and economic damage, there is a growing trend toward small renewable technologies that are well matched to end-user needs and operating conditions. As demand grows and markets expand, investment capital will be drawn to the industry and new growth trends will emerge. The photovoltaic industry around the world achieved record shipments also. Worldwide shipments of photovoltaic (PV) modules for 1989 totaled more than 40 megawatts (MW), nearly a 20 percent increase over last year's shipments. The previous two years showed increases in worldwide shipments of 23 and 25 percent, respectively. If this growth rate continues through the 1990s, as industry back orders would indicate, 300 to 1000 MW of PV-supplied power could be on line by 2000. Photovoltaic systems have low environmental impact and they are inexpensive to operate and maintain. Using solid-state technology, PV systems directly convert sunlight to electricity without high-temperature fluids or moving parts that could cause mechanical failure. This makes the technology very reliable.

    Full Text Available Nowadays renewable sources are preferred over the non renewable source to generate the energy. The rapid rates of exhausting non-renewable resources have completed us to look out for new avenues in energy generation. According to global energy scenario, developed countries are adopting renewable resources as major source of energy. Geothermal energy originates from the original formation of the planet, from radioactive decay of minerals, and from solar energy absorbed at the surface. Geothermal energy is derived from the hot interior of the earth. The earth is a reservoir of heat energy, most of which is buried and is observed during episodes of volcanic eruption at the surfaces. Geothermal is one of the most promising renewable source of energy which is plentiful, eco-friendly, reliable and clean source of energy available in earth crust. In our country there is wide scope for the utilization of geothermal energy with proper strategically approach to meet the energy requirement. The future prospects of this heat energy as a sustainable source of renewable energy are indeed promising. Today India is the fifth largest consumer of electricity and by 2030 it will become third largest overtaking Japan and Russia according to statistical data available by Energy Planning Commission, Government of India.

    2002-03-01

    Renewable energy offers the possibility of providing a complete, sustainable energy infrastructure without anthropogenic emission of CO2. Large-scale implementation of renewable technologies would eliminate the need to develop and implement sequestration systems, by reducing the use of, and ultimately eliminating fossil based energy production. Renewable energy also offers energy security because indigenous resources are sufficient. The major renewable energy systems include phovoltaics (solar cells), solar thermal (electric and thermal), wind, biomass (plants and trees), hydroelectric, ocean, and geothermal. Given the intermittent nature of solar energy, only those energy systems that are coupled to an energy storage technology will be viable. Among the energy storage technologies are hydrogen, batteries, flywheels, superconductivity, ultracapacitors, pumped hydro, molten salts (for thermal storage), and compressed gas. One of the most versatile energy storage systems and the best energy carrier for transportation is hydrogen. This talk will review some of the basic renewable energy systems, present possible pathways for the implementation of hydrogen into the energy infrastructure and offer research areas that need to be addressed to increase the viability of these renewable energy technologies.

    The aim of this book is to illustrate the interaction between architecture and energy in an overall perspective starting from the new energy requirements. Architects make a lot of form related outlines early in the design process, and these have significant consequences for the energy consumption. Furthermore, the new energy requirements start from an overall evaluation, during which the architectural form is of decisive importance to minimization of the energy consumption. The book focuses on four themes: a) day lighting, which plays a decisive part in relation to our health and wellness inside buildings, b) solar heating; passive solar heating has traditionally been playing an important part in low-energy architecture, c) rough house; choice of materials can both increase and decrease buildings' energy consumption, and d) technology; modern buildings use a number of energy demanding installations, therefore the interaction between technology and energy is examined.

    In the transition towards a 100% renewable energy system, energy savings are essential. The possibility of energy savings through conservation or efficiency increases can be identified in, for instance, the heating and electricity sectors, in industry, and in transport. Several studies point...... to various optimal levels of savings in the different sectors of the energy system. However, these studies do not investigate the idea of energy savings being system dependent. This paper argues that such system dependency is critical to understand, as it does not make sense to analyse an energy saving...... without taking into account the actual benefit of the saving in relation to the energy system. The study therefore identifies a need to understand how saving methods may interact with each other and the system in which they are conducted.

  9. Energy consumption: energy consumption in mainland Norway

    Energy Technology Data Exchange (ETDEWEB)

    Magnussen, Inger Helene; Killingland, Magnus; Spilde, Dag

    2012-07-25

    The purpose of this report is to describe trends in energy consumption in mainland Norway, with an emphasis on key trends within the largest consumer groups. We also explain common terms and concepts in the field of energy consumption. Finally, we look at forecasts for future energy consumption, produced by bodies outside NVE. Total final energy consumption in mainland Norway in 2009 was 207 TWh. The most important end-user groups are households, service industries, manufacturing industry and transport. In addition, the energy sector in mainland Norway consumed 15 TWh. Energy consumed in the energy sector is not considered as final consumption, as the energy is used to produce new energy products. The long-term trend in energy consumption in mainland Norway is that fuel in the transport sector and electricity for the energy sector increases, while energy consumption in other sectors flattens out. The main reason for an increased use of fuel in the transport sector is the rise in the number of motorised machinery and vehicles in mainland Norway. This has caused a rise in gasoline and diesel consumption of 75 per cent since 1976. The petroleum sector is the largest consumer of energy within the energy sector in mainland Norway, and electricity from onshore to platforms in the North Sea and to new shore side installations has led to a rise in electricity consumption from 1 TWh in 1995 to 5 TWh in 2009. The energy consumption in households showed flat trend from 1996 to 2009, after many years of growth. The main reasons are a warmer climate, higher energy prices, the use of heats pumps and more energy-efficient buildings. In the service industries, the growth in energy consumptions has slightly decreased since the late 1990s, for much the same reasons as for households. In manufacturing industries the energy consumption have flatten out mainly due to the closure of energy-intensive businesses and the establishment of new more energy-efficient businesses.

    It is often highlighted how the transition to renewable energy supply calls for significant electricity storage. However, one has to move beyond the electricity-only focus and take a holistic energy system view to identify optimal solutions for integrating renewable energy. In this paper......, an integrated cross-sector approach is used to determine the most efficient and least-cost storage options for the entire renewable energy system concluding that the best storage solutions cannot be found through analyses focusing on the individual sub-sectors. Electricity storage is not the optimum solution...... to integrate large inflows of fluctuating renewable energy, since more efficient and cheaper options can be found by integrating the electricity sector with other parts of the energy system and by this creating a Smart Energy System. Nevertheless, this does not imply that electricity storage should...

    Zheng, Nina; Fridley, David

    2011-06-15

    In addition to promoting energy efficiency, China has actively pursued alternative energy development as a strategy to reduce its energy demand and carbon emissions. One area of particular focus has been to raise the share of alternative energy in China’s rapidly growing electricity generation with a 2020 target of 15% share of total primary energy. Over the last ten years, China has established several major renewable energy regulations along with programs and subsidies to encourage the growth of non-fossil alternative energy including solar, wind, nuclear, hydro, geothermal and biomass power as well as biofuels and coal alternatives. This study thus seeks to examine China’s alternative energy in terms of what has and will continue to drive alternative energy development in China as well as analyze in depth the growth potential and challenges facing each specific technology. This study found that despite recent policies enabling extraordinary capacity and investment growth, alternative energy technologies face constraints and barriers to growth. For relatively new technologies that have not achieved commercialization such as concentrated solar thermal, geothermal and biomass power, China faces technological limitations to expanding the scale of installed capacity. While some alternative technologies such as hydropower and coal alternatives have been slowed by uneven and often changing market and policy support, others such as wind and solar PV have encountered physical and institutional barriers to grid integration. Lastly, all alternative energy technologies face constraints in human resources and raw material resources including land and water, with some facing supply limitations in critical elements such as uranium for nuclear, neodymium for wind and rare earth metals for advanced solar PV. In light of China’s potential for and barriers to growth, the resource and energy requirement for alternative energy technologies were modeled and scenario analysis

    Science.gov (United States)

    1991-12-01

    The mission of the Geothermal Energy Program is to develop the science and technology necessary for tapping our nation's tremendous heat energy sources contained within the Earth. Geothermal energy is a domestic energy source that can produce clean, reliable, cost-effective heat and electricity for our nation's energy needs. Geothermal energy - the heat of the Earth - is one of our nation's most abundant energy resources. In fact, geothermal energy represents nearly 40 percent of the total U.S. energy resource base and already provides an important contribution to our nation's energy needs. Geothermal energy systems can provide clean, reliable, cost-effective energy for our nation's industries, businesses, and homes in the form of heat and electricity. The U.S. Department of Energy's (DOE) Geothermal Energy Program sponsors research aimed at developing the science and technology necessary for utilizing this resource more fully. Geothermal energy originates from the Earth's interior. The hottest fluids and rocks at accessible depths are associated with recent volcanic activity in the western states. In some places, heat comes to the surface as natural hot water or steam, which have been used since prehistoric times for cooking and bathing. Today, wells convey the heat from deep in the Earth to electric generators, factories, farms, and homes. The competitiveness of power generation with lower quality hydrothermal fluids, geopressured brines, hot dry rock, and magma (the four types of geothermal energy), still depends on the technical advancements sought by DOE's Geothermal Energy Program.

    Making the energy consumption more efficient in Denmark by means of energy saving are connected to the Danish government's overall National Growth Strategy. A reduced consumption of energy as a result of economic attractive energy saving initiatives leads to reduced energy costs and consequently an improvement of Denmark's competitive power. Furthermore, reducing the energy consumption decreases the vulnerability towards rising energy prices, and the security of supplies is increased. Finally energy conservation serves as a means of reducing environmental impact from the energy sector. Energy consumption is not damaging to the environment in itself, however, to the extent that energy consumption causes negative impact on the environment, e.g. through discharge of environmentally damaging substances generated during energy production, a reduction of the energy consumption will benefit the environment. Energy saving in itself does not lead to a decrease in CO{sub 2} emission in Denmark unless it is accompanied by an adjustment of CO{sub 2} quotas on production of electricity. The Danish Government emphasizes that the energy saving efforts are cost-effective both for the society and for the consumers. The energy saving report contains an updated projection of the Danish energy consumption and an evaluation of the impacts of the energy saving efforts. The impacts of more effective end use of energy are described, and an account of the barriers preventing the realization of a number of potential economic attractive energy saving initiatives is made. Finally the energy saving report presents a number of proposals for new energy saving initiatives. (BA)

    The National Energy Act of 1978 contains many provisions that will significantly affect solar technology commercialization and solar energy users. Four of the five statutes that comprise the National Energy Act deserve close attention. The National Energy Conservation Policy Act will promote residential solar installations. The Energy Tax Act will accelerate both residential and commercial solar system applications. The Public Utilities Regulatory Policies Act promotes efficient use of utility resources as well as decentralized power production. And, the Power Plan and Industrial Fuel Use Act places severe restrictions on future burning of petroleum and natural gas, which should lead some operators to build or convert to solar energy systems. Each of the preceding acts are considered in separate sections of this report. Federal regulations issued pursuant to the various provisions are also identified and discussed, and some of the problems with the provisions and regulations are noted.

    Detailed, complete, timely and reliable statistics are essential to monitor the energy situation at a country level as well as at an international level. Energy statistics on supply, trade, stocks, transformation and demand are indeed the basis for any sound energy policy decision. For instance, the market of oil -- which is the largest traded commodity worldwide -- needs to be closely monitored in order for all market players to know at any time what is produced, traded, stocked and consumed and by whom. In view of the role and importance of energy in world development, one would expect that basic energy information to be readily available and reliable. This is not always the case and one can even observe a decline in the quality, coverage and timeliness of energy statistics over the last few years.

    The third conference of parties to the UN convention on climate change (COP3) decided the strict reduction ratio of CO{sub 2} gas, and therefore, further efforts to reduce energy consumption must be made. Also, various original ideas and inventive activities are required to meet ISO14001 rapidly becoming popular and the regulations of the amendment to the Energy Saving Act. Especially the amendment stipulates concrete examples, devices and systems unlike the former. This suggests a policy to tighten liability and penal regulations for reduction in energy consumption and bring actual results.

    Energy is a crosscutting concept in science and features prominently in national science education documents. In the Next Generation Science Standards, the primary conceptual learning goal is for learners to conserve energy as they track the transfers and transformations of energy within, into, or out of the system of interest in complex physical processes. As part of tracking energy transfers among objects, learners should (i) distinguish energy from matter, including recognizing that energy flow does not uniformly align with the movement of matter, and should (ii) identify specific mechanisms by which energy is transferred among objects, such as mechanical work and thermal conduction. As part of tracking energy transformations within objects, learners should (iii) associate specific forms with specific models and indicators (e.g., kinetic energy with speed and/or coordinated motion of molecules, thermal energy with random molecular motion and/or temperature) and (iv) identify specific mechanisms by which energy is converted from one form to another, such as incandescence and metabolism. Eventually, we may hope for learners to be able to optimize systems to maximize some energy transfers and transformations and minimize others, subject to constraints based in both imputed mechanism (e.g., objects must have motion energy in order for gravitational energy to change) and the second law of thermodynamics (e.g., heating is irreversible). We hypothesize that a subsequent goal of energy learning—innovating to meet socially relevant needs—depends crucially on the extent to which these goals have been met.

    Henriksen, Thormod; Kanestroem, Ingolf

    2001-07-01

    This book explains what is understood by climate systems and the concept of greenhouse effect. It also gives a survey of the world's energy consumption, energy reserves and renewable energy sources. Today, 75 - 80 per cent of the world's energy consumption involves fossil fuel. These are the sources that cause the CO{sub 2} emissions. What are the possibilities of reducing the emissions? The world's population is increasing, and to provide food and a worthy life for everybody we have to use more energy. Where do we get this energy from without causing great climate changes and environmental changes? Should gas power plants be built in Norway? Should Swedish nuclear power plants be shut down, or is it advisable to concentrate on nuclear power, worldwide, this century, to reduce the CO{sub 2} emissions until the renewable energy sources have been developed and can take over once the petroleum sources have been depleted? The book also discusses the global magnetic field, which protects against particle radiation from space and which gives rise to the aurora borealis. The book is aimed at students taking environmental courses in universities and colleges, but is also of interest for anybody concerned about climate questions, energy sources and living standard.

    The Energy Factory is a collaboration of 26 Dutch local water boards in which options for energy saving and energy production are examined. According to the authors, the initiative of the Energy Factory will lead to a reframing of the role of the water boards. Moreover, they explain how the PPP concept (People, Planet, Profit) may act as platform for negotiations between actors who are involved in the Energy Factory. In addition, the PPP concept is used to demonstrate that the Energy Factory will lead to larger social involvement, social entrepreneurship and growing profits [Dutch] De Energiefabriek is een samenwerkingsverband van 26 waterschappen in Nederland waarin wordt gezocht naar mogelijkheden om energie te besparen en zelf energie te produceren. Volgens de auteurs van deze notitie leidt het initiatief van de Energiefabriek tot een reframing van de rol van waterschappen. Daarnaast leggen ze uit hoe het PPP-concept (People, Profit, Planet) kan fungeren als platform voor onderhandelingen tussen de actoren die betrokken zijn bij de Energiefabriek. Verder wordt met het PPP-concept aangetoond dat de Energiefabriek leidt tot ruimere maatschappelijke betrokkenheid, maatschappelijk ondernemen en winstvergroting.

  1. Radiant energy to electric energy converter

    Science.gov (United States)

    Sher, Arden (Inventor)

    1980-01-01

    Radiant energy is converted into electric energy by irradiating a capacitor including an ionic dielectric. The dielectric is a sintered crystal superionic conductor, e.g., lanthanum trifluoride, lanthanum trichloride, or silver bromide, so that a multiplicity of crystallites exist between electrodes of the capacitor. The radiant energy cyclically irradiates the dielectric so that the dielectric exhibits a cyclic photocapacitive like effect. Adjacent crystallites have abutting surfaces that enable the crystallites to effectively form a multiplicity of series capacitor elements between the electrodes. Each of the capacitor elements has a dipole layer only on or near its surface. The capacitor is initially charged to a voltage just below the dielectric breakdown voltage by connecting it across a DC source causing a current to flow through a charging resistor to the dielectric. The device can be utilized as a radiant energy detector or as a solar energy cell.

    The international energy situation has entered a new phase of change and readjustment. On the one hand, while imbalances in petroleum market supply-demand have been alleviated , the consuming states are now focusing on demand side management and development of new and renewable energy. There has been great progress in international energy security dialogue and cooperation. On the other hand , supply-demand market balance remains fragile , and restrictions due to insufficient energy investment are more evident. The concerned states have taken a stronger grip over their own resources. Implementation of energy diplomacy has also further complicated the relationship between energy and geo-politics, causing an upsurge of competition.

    The present and projected energy requirements for the United States are discussed. The energy consumption and demand sectors are divided into the categories: residential and commercial, transportation, and industrial and electrical generation (utilities). All sectors except electrical generation use varying amounts of fossile fuel resources for non-energy purposes. The highest percentage of non-energy use by sector is industrial with 71.3 percent. The household and commercial sector uses 28.4 percent, and transportation about 0.3 percent. Graphs are developed to project fossil fuel demands for non-energy purposes and the perdentage of the total fossil fuel used for non-energy needs.

    Energy issues such as pollution, resource depletion, global warming, nuclear power and waste are problems demanding timely solutions. This book provides a critical examination of the resources, market forces, and social impacts of modern energy production. The book addresses the dilemmas that have arisen due to society's crucial dependence on energy, particularly fossil fuels, and explores the available alternative energy producing technologies. The second edition has increased emphasis on those issues at the forefront of the current energy debate: energy sustainability, climate change, and the radical restructuring of the power industry due to deregulation. Assuming no prior technical expertise and avoiding complex mathematical formulation. The second edition, like the first, will be especially useful as a textbook for undergraduate programs in Science, Technology and Society (STS), and as a supplementary text in a variety of courses that touch on energy studies, including environmental and technology policy, environmental, mineral and business law, energy and resource economics.

    Dynich, Raman A., E-mail: dynich@solo.by [Institute of Social Educational Technologies (Belarus)

    2015-06-15

    The paper considers the energy exchange process of the electromagnetic wave with a spherical metal nanoparticle. Based on the account of the temporal dependencies of electric and magnetic fields, the author presents an analytical dependence of the energy flow passing through the spherical surface. It is shown that the electromagnetic energy, localized in metal nanoparticles, is not a stationary value and periodically varies with time. A consequence of the energy nonstationarity is a nonradiating exit of the electromagnetic energy out of the nanoparticle. During the time equal to the period of wave oscillations, the electromagnetic energy is penetrating twice into the particle and quits it twice. The particle warms up because of the difference in the incoming and outgoing energies. Such “energy breathing” is presented for spherical Ag and Au nanoparticles with radii of 10 and 33 nm, respectively. Calculations were conducted for these nanoparticles embedded into the cell cytoplasm near the frequencies of their surface plasmon resonances.

    Denmark has a long tradition of active energy policy, initiated by the first oil crisis in 1973. Over the years, numerous actions have been taken on the basis of a broad consensus in the Danish Parliament - both in order to reduce the energy consumption and in order to increase the share of renewable energy. Now, the cornerstones for the Danish energy future have also been laid. The Danish Government has set the long-term goal to abandon fossil fuels by 2050. An important milestone was reached in March 2012 with an Energy Agreement for the period 2012-2020 - again based on a broad consensus in the Danish Parliament. This Agreement contains a wide range of ambitious initiatives, bringing Denmark a good step closer to the target of 100% renewable energy. In the present publication, a selection of past and present Danish energy policies is presented, together with the results achieved in terms of energy savings, use of renewables etc. (LN)

    ⎯After the Fukushima disaster, European politicians began to reassess the energy strategy for their countries. The focus is now on renewable energy sources and as a result on decentralization. The decentralized generation, storage, and of course the consumption of energy is the central point. Now with the new develop-ments under the roof of energy turnaround the way back from the centralized architecture of our energy system to a more decentralized one is predetermined. Decentralization implies the change in the role of today’s consumers. They become energy prosumers. This is the basis for the crowd energy concept. In this position paper the crowd energy concept is introduced and necessary research fields are identified.

    The foundry industry is a significant user of energy, and therefore, a natural candidate for efforts to save energy and improve efficiency by both governmental agencies and technical/trade associations. These efforts are designed to both improve the national energy position and improve the industry's efficiency and profitability. Increased energy cost and the reduced availability of fossil fuels at certain times have provided the incentive to curb waste and to utilize purchased energy wisely. Energy costs now approach and sometimes exceed 10% of the sales dollar of many foundries. Although energy use by foundries has gradually decreased on a per/ton basis in recent years, the foundry industry must continue to find ways to utilize energy more efficiently. This workbook provides ways to achieve this goal.

    Hopkins, Matt

    Wind energy has emerged as one of the fastest growing energy sources in the United States over the course of the last decade. It is the renewable energy type most readily defining clean economy leadership. An uncertain policy context, public conflicts over the impacts of turbine installations, and unsorted connections to a national green development strategy raise questions about the continued viability of wind power in the U.S. This thesis attempts to document and question some of the issues raised by wind energy expansion in the U.S. generally, but in Maine in particular, in order to explain how environmental, social, and economic benefits accrue to places hosting wind projects. The available information combined with a targeted inquiry produce insights into how the state of Maine can improve its wind development policies and outcomes.

  7. Magnetic resonance energy and topological resonance energy.

    2016-04-28

    Ring-current diamagnetism of a polycyclic π-system is closely associated with thermodynamic stability due to the individual circuits. Magnetic resonance energy (MRE), derived from the ring-current diamagnetic susceptibility, was explored in conjunction with graph-theoretically defined topological resonance energy (TRE). For many aromatic molecules, MRE is highly correlative with TRE with a correlation coefficient of 0.996. For all π-systems studied, MRE has the same sign as TRE. The only trouble with MRE may be that some antiaromatic and non-alternant species exhibit unusually large MRE-to-TRE ratios. This kind of difficulty can in principle be overcome by prior geometry-optimisation or by changing spin multiplicity. Apart from the semi-empirical resonance-theory resonance energy, MRE is considered as the first aromatic stabilisation energy (ASE) defined without referring to any hypothetical polyene reference.

    Seiferlein, Katherine E. [USDOE Energy Information Administration (EIA), Washington, DC (United States)

    2000-07-01

    A generation ago the Ford Foundation convened a group of experts to explore and assess the Nation’s energy future, and published their conclusions in A Time To Choose: America’s Energy Future (Cambridge, MA: Ballinger, 1974). The Energy Policy Project developed scenarios of U.S. potential energy use in 1985 and 2000. Now, with 1985 well behind us and 2000 nearly on the record books, it may be of interest to take a look back to see what actually happened and consider what it means for our future. The study group sketched three primary scenarios with differing assumptions about the growth of energy use. The Historical Growth scenario assumed that U.S. energy consumption would continue to expand by 3.4 percent per year, the average rate from 1950 to 1970. This scenario assumed no intentional efforts to change the pattern of consumption, only efforts to encourage development of our energy supply. The Technical Fix scenario anticipated a “conscious national effort to use energy more efficiently through engineering know-how." The Zero Energy Growth scenario, while not clamping down on the economy or calling for austerity, incorporated the Technical Fix efficiencies plus additional efficiencies. This third path anticipated that economic growth would depend less on energy-intensive industries and more on those that require less energy, i.e., the service sector. In 2000, total energy consumption was projected to be 187 quadrillion British thermal units (Btu) in the Historical Growth case, 124 quadrillion Btu in the Technical Fix case, and 100 quadrillion Btu in the Zero Energy Growth case. The Annual Energy Review 1999 reports a preliminary total consumption for 1999 of 97 quadrillion Btu (see Table 1.1), and the Energy Information Administration’s Short-Term Energy Outlook (April 2000) forecasts total energy consumption of 98 quadrillion Btu in 2000. What energy consumption path did the United States actually travel to get from 1974, when the scenarios were drawn

Energy in Sweden 2004, together with its statistics supplement, Energy in Sweden: Facts and Figures 2004, is intended to provide decision-makers, journalists and the public with a single source of easily available information on conditions and developments in the energy sector. In recent years, Swedish energy and environmental policy has been increasingly concentrated on establishing or improving the long-term conditions for efficient energy markets and efficient use of energy. Restructuring of the Swedish electricity market, greater internationalisation and the effects of the energy system on the wider environment and on climate are important factors that influence the direction of energy policy and so also development of the energy markets. The line that was started by the 2002 Energy Policy Agreement, under the name of Working Together for a Reliable, Efficient and Environmentally Aware Energy Supply (Bill no. 2001/02:143), continues. The shift in taxation policy to encourage the move towards a sustainable energy system and reduced environmental impact continues, as exemplified by the introduction of the electricity certificate system on 1st May 2003. The negotiations that were started in 2003 with a view to progressive shut-down of nuclear power generation were broken off in October 2004 without having reached agreement with the nuclear power companies. As soon as the breakdown of the negotiations was announced, the Government, together with the Left Party and the Centre Party, stated that Barsebaeck 2 will be closed in 2005. Sweden's climate policy is based on the Climate Strategy Act (Bill no. 2001/02:55), which was adopted by Parliament in March 2002. It is expected that trading in emission rights, in accordance with the EU Emissions Trading Directive, will start in January 2005, with publication of national emission rights allocations on 30th September 2004.

    Energy acquisition through suckling has been widely studied in rat and human infants. Processes mediating energy conservation, however, have not received the attention that they deserve. This essay, in honor of Professor Jerry Hogan, discusses parallel behaviors used by rat and human mothers to minimize energy loss in their offspring. Parallel mechanisms underlying energy preservation have been identified in rats and humans, suggesting phylogenetic conservation and possibly continuity. This article is part of a Special Issue entitled: In Honor of Jerry Hogan.
