    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. Dazu werden - neben einer Diskussion des derzeitigen energiewirtschaftlichen Rahmens - fuer die

    To judge future trends in work on the exploitation of renewable energy sources for overall energy supply, it is necessary to know the following: the rules that nature abides by, the principles of technical exploitation of these energies, and the basic data for the current state of development. The above information is compiled in this publication for those renewable energy sources on which topical discussion centres: solar radiation and wind. For the remaining renowable energy sources (e.g. biomass, tidal power, geothermal energy), some examples of use are mentioned and advanced literature is indicated. (orig./HSCH).

    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 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. Kasseler Symposium Energie-Systemtechnik - Erneuerbare Energien und Rationelle Energieverwendung. 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. Kritische Zustaende koennen entdeckt und in der Entwicklung der Hardware entsprechend beruecksichtigt werden. Fehler

    The Erneuerbare-Energien-Waermegesetz (EEG) is the first legislation ever that dictates the use of renewable energy sources for new buildings. By 2020, the share of renewables in end use energy consumption is to amount to 14 %. The new law came into force on 1 January 2009 and has initiated all kinds of prognoses. It appears that a world-wide energy revolution may have begun. This is the first of a series of articles in ISOLIERTECHNIK on all relevant renewable energy sources. (orig.)

    The German Renewables Act, EEG, specified a guaranteed reimbursement rate for electric power from renewable energy sources. Normally, the reimbursement rate is far higher than the market value of the power generated and thus makes the plant economically interesting for its owner. It remains to be seen if the renewable energy sources with the biggest potential, i.e. wind power and solar power, will have to be subsidized indefinitely, or whether they can find their place in the electricity market also without the EEG and other funding mechanisms.

    The number of jobs in the field of renewable energy sources is disproportionately high as compared to conventional energy sources. For example, the German wind industry has 30,000 jobs for a 3% share in power supply. According to the White Book on Renewable Energy Sources of the European Commission, the share of renewable energy sources is to be increased to 12% by 2010. This will mean 1.2 million new jobs. If the share is increased to 20%, 2 million new jobs will be created in the European Union according to an EUROSOLAR study. [German] Die erneuerbaren Energien haben im Verhaeltnis zu konventionellen Energietraegern ein ueberproportional hohes Arbeitsplatzangebot. So sind bereits heute in der deutschen Windenergiebranche, die zur Zeit etwa 3 Prozent des Stromverbrauchs deckt, 30000 Menschen beschaeftigt. Das Weissbuch der Europaeischen Kommission ueber erneuerbare Energien hat das Ziel formuliert, den Anteil der erneuerbaren Energien bis zum Jahr 2010 auf 12 Prozent zu steigern. Die Europaeische Kommission sieht damit die Schaffung von 1,2 Millionen Arbeitsplaetzen verbunden. Wenn der Anteil der erneuerbaren Energien in der Europaeischen Union auf 20 Prozent erhoeht wird, werden gemaess einer EUROSOLAR - Studie in der EU sogar 2 Millionen neue Arbeitsplaetze entstehen.

    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.

    The petroleum resources are diminishing; resource conflicts invoke the new wars of our century. With increasing energy demand the world races to its existential crisis. The renaissance of nuclear energy is therefore strongly promoted and energy industry is trying by all means to keep their predominance. It is gaming with fire, since only a holistic change over to the use of renewable energy sources can secure global energy demand. Why is rethinking so difficult and what strategies and technologies can help? Hermann Scheer descibes in his new book the manifold mental barriers, the power of traditional energy-thinking, but he also shows, how the change to renewables can be done and made irreversible. The archimedic point is energy autonomy - a manifold feasible, technological, and economical concept. Energy autonomy can only be achieved with renewables and can be used at once and anywhere: decentralized, individually, with immediate noticable consequences. The new policy for renewables, developed by Scheer, frees the energy discussions from its prison fo specialized energy thinking. A ideational and practical guideline for the overdue energy change.

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

Renewable energy 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. Dies bedeutet nicht automatisch, dass in diesen Situationen Grossstoerungen (''Blackouts'') entstanden waeren, da die Betrachtung

    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.

    This comprehensive, illustrated report for the Swiss Federal Office of Energy (SFOE) presents the findings of a project that examined the electricity consumption of saw-mills and ways in which the amount of electrical power used in such facilities could be reduced. The Schilliger Holz AG company was taken as an example of a saw-mill in Switzerland. Its power consumption in 2001 was almost 6 gigawatt-hours. The work done in the two phases of the project is described and commented on. The first phase involved the measurement and analysis of power consumption; in the second phase measures to be taken to help save energy were developed. The various machinery and installations in this saw mill are described. These include various systems for the processing of the raw timber through to finished products that include wood for building, decoration and laminates. Measurement data is presented and commented on. Potentials for saving electricity and measures to be taken are described in detail for the various processing plants in the saw-mill.

    The sustainable and efficient production of renewable energy from agricultural resources is an active contribution to the climate protection. This is a serious issue for farmers, particularly as the climatic change affects the production of the farmers. The brochure under consideration shows how farmers can not only produce energy efficiently, but also use energy at their own farms. With this, not only an independence from the energy suppliers is achieved, but also the energy supply is supplied.

    Making use of energy from renewable sources has strategic and security-policy relevance. Since DB AG is a major energy consumer, the use of energy from renewable sources in railway operations will make economic sense in the long run. The railways depend on a very high security of energy supply nationwide. Efficient energy management can help enhance the security of supply to the railways. In addition, there are large potential energy savings to be made in railway operations. Major efforts are required to reach this objective. Using energy from renewable sources and increasing energy efficiency are two indispensable prerequisites for a sustainable energy supply to the railways as well as for increasing their attractiveness.

    This brochure presents a picture of the rapid development of renewable energy sources in the years between 1990 and 2007. It shows the rapid growth and informs on the importance of renewable energy sources for climate protection. The new CDU/FDP government headed by Angela Merkel stressed its intention to develop the potential of renewable energy sources. Apart from the effect of higher energy efficiency, this will also help Germany to make an ambitious contribution to climate protection world-wide. Renewable energy sources are to provide the biggest share of power supply in the future. By 2020, the EEG (German Renewables Act) envisages at least a 30 percent share for renewable energy sources as an intermediate goal. In the field of heat supply, at least 14 percent are envisaged fro 2020. (orig./RHM)

    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.

    In contrast to the record breaking speed with which the German government presented its new energy concept in response to the Fukushima reactor disaster, the practical task of transforming our energy supply system will take decades. One of the greatest challenges involved in the energy turnaround will be that of integrating renewable energies into the power supply system. A holistic analysis and assessment of all aspects involved in this is therefore of utmost importance. Under the focal topic of its new publication ''Energie fuer Deutschland 2011'', Weltenergierat Deutschland e.V. presents a detailed summary of this challenge, thus providing a basis for further discussion. It shows that efficient integration of renewable energies must necessarily involve a combination of systems engineering and organisational measures.

    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.

    The present publication is dedicated to renewable energies. The move to a new energy and climate policy impinges on many central humanistic issues (including issues of a legal, economic, sociological, ethical and politological nature). How is it possible to resolve the ambivalences that are associated with the use of renewable energies and which draw our attention not only to renewable energies as such but also to issues of energy efficiency and sufficiency. What political and economic instruments are needed in order to accelerate the market entry of renewable energies and at the same time contain the ambivalences associated with them? And what questions of legal interpretation result from the application of such instruments in practice, be it in the context of subsidies under the Renewable Energy Law or the laws on the planning of building projects. And where lie the causes of the fact seen here that so many individuals in business, the political realm and the public at large are finding it hard to go with the transition to renewable energies?.

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

    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 heating sector holds high potentials for cutting CO{sub 2} emissions by using renewable energy. These potentials can be tapped either by substituting fossil fuels in individual heating units or by using renewable energy in district heating networks, which may be more efficient. This paper asks for the options to increase the share of renewable energy in Germany's district heating infrastructure and for the restrictions that are hampering further development in this field. It critically discusses the relevant technical, political and economic challenges and determinants. District heating networks fuelled by renewable energy are not only competing with fossil fuels in individual heating units. They are also facing the more fundamental question regarding the preconditions for a profitable and worthwhile operation of grid-bound heat supply. The economic viability of heat grids has to be analyzed on a case-by-case basis, since it depends predominantly on individual framework conditions. Those include a decreasing heat demand due to improving energy performance of buildings, competing gas grids already in place and the complex interest structures of the actors involved. The growth rates that were observed in the last years were predominantly achieved in small renewably fuelled district heating networks. Even under favourable framework conditions, there is a need for additional supportive measures to increase the share of renewable energy in district heating grids. This mix of policy instruments should encompass measures to increase the implementation rates of municipal heat utilization concepts, measures to decrease the initial investments needed, as well as public relations to improve the user perception of grid-bound heat supply. However, the options to increase the share of renewable heat in existing large-scale grids are considered to be rather limited. (orig.)

    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.

    Capacity markets such as the decentralised performance market as demanded by the electricity economy put wind power and photovoltaic plants at a disadvantage. The author therefore argues against the establishment of a capacity market and in favour of making better use of the electricity market's already existing significant potential for further development, specifically through: flexibilisation of exchange electricity markets, closer coupling between exchange electricity markets and control energy markets, and incorporation of electricity consumers into the market mechanism. This would at the same time serve to meet a decisive prerequisite for a smooth transition from today's to tomorrow's electricity supply, and that is a single electricity market for conventional power plants as well as electricity production plants fuelled with renewable resources, whether or not entailing fuel costs, in which all types of plants compete with each other on a level playing field. If a capacity market should prove necessary after all in a few years, it can still be set up. Safeguarding security of supply is of vital importance for both the economy and society at large. For emergencies a strategic reserve with a capacity of several GW should therefore be created, and the Ordinance on Reserve Power Plants should be amended to this effect. The establishment by the Renewable Energy Law of 2014 of an obligation of direct marketing for wind power and photovoltaic plants appears to have been premature considering the deficits of the electricity market and the large fleet of inflexible conventional power plants. What is needed now is a near-term flexibilisation of the electricity market and reform of the CO{sub 2} emissions trading scheme.

    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 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

    This article examines different modes of electrolyzers in two future scenarios of the German energy system. It turns out that hydrolyzers need a high utilization to pay for themselves. An economic operation in 2030 in the scenario of moderate expansion of renewable energies is not possible. At strong expansion the investment is profitable when high revenues from secondary control power provision can be achieved. Generally it is clear that the secondary control power provision and also the direct sales of hydrogen in industry or in the transport sector allows higher revenues than the storage and reconversion. [German] Der Beitrag untersucht verschiedene Betriebsweisen von Elektrolyseuren in zwei Zukunftsszenarien des deutschen Energiesystems. Es zeigt sich, dass Elektrolyseure eine hohe Auslastung benoetigen, um sich zu amortisieren. Ein wirtschaftlicher Betrieb ist bis 2030 im Szenario mit moderatem Ausbau Erneuerbarer Energien nicht moeglich. Bei starkem Ausbau rentiert sich die Investition, wenn hohe Erloese aus Sekundaerregelleistungsvorhaltung erzielt werden koennen. Allgemein wird deutlich, dass die Sekundaerregelleistungsvorhaltung und auch der direkte Absatz von Wasserstoff in der Industrie oder im Verkehrssektor hoehere Erloese ermoeglichen als die Speicherung und Rueckverstromung.

    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.

    On 23rd January, 2008, the European Commission submitted its package to the climatic and energy policy. Beside the parliamentary bills for the reduction of the greenhouse gas emissions, a central component of this package is the parliamentary bill for the development of renewable energies in Europe. As a consequence, the race around the finite energy sources is intensified, and the dependence from imports will increase dramatically. Under this aspect, the author of the contribution under consideration reports on development strategies of the European Union for renewable energies. The guideline proposal, submitted at 23rd January, 2008, plans that the member states of the European Union transfer their ''origin certificates'' for electricity, thermal energy and coldness from renewable energies only to another country, if they achieved their respective intermediate objective. Additionally, the member states have to decide whether they participate at the certificate trade or not.

  13. Renewable energy in the tourism sector - For example at campgrounds; Erneuerbare Energien im Tourismussektor am Beispiel von Campingplaetzen

    2006-07-01

    Summary: The lecture deals with the use of renewable energies in the tourism sector e.g. at campgrounds. At campsites solar energy is mainly used to heat water and to supplement conventional heating; the production of solar energy, however, is rather the exception. Also wood as energy source is increasingly used at campsites whilst wind energy is a marginal source as considerable noise or shadow of the wind power plants would scare away holiday makers. Environmentally conscious tourist facilities additionally purchase 'green energy' to improve their climatic balance. CO{sub 2} emissions can be reduced through the use of biodiesel or vegetal oil as an engine fuel in in-house vehicles. (orig.)

    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)

    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.)

    South Africa's energy footprint is currently mainly based on fossil fuels. This gives the country access to very inexpensive electricity, but is also associated with high greenhouse gas emissions. The government's policy of inviting tenders for renewable energy projects not only aims at securing the energy supply but also pursues the goal of sustainable, environmentally acceptable growth and of creating incentives for the development of a domestic industry in this sector. To date the country's electricity production rests almost entirely with Escom, a state-owned energy supplier which also operates South Africa's transmission network. In response to this, efforts are now being made to diversify the energy supply system with the participation of new electricity producers. As a result, investment opportunities in the South African energy sector are on the whole becoming increasingly attractive for foreign investors.

    If we mean to secure the future of this planet in its present state we shall have to reduce drastically the emissions of trace gases influencing our climate like CO/sub 2/, CH/sub 4/, FCHC, ozone, N/sub 2/O and stratospheric H/sub 2/O. CO/sub -/neutral energy sources in clude nuclear energy and regenerative energies (solar, wind, water, biomass, tidal energy). These energy sources provide energy carriers in terms of electricity, heat, biofuels, synthesis gas and hydrogen. The author discusses the power/hydrogen energy system, electrolytic generation of hydrogen and its capacity for storage and transport from sunny solar-energy utilization areas (Central Africa). Hydrogen can then be used in drive systems, power generation (power stations) and for space heating and process heat. The author discusses its profitability and underlines the fact that hydrogen will figure in the energy economy of the future. (HWJ).

    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.

    Rural areas in Bavaria are faced with the same challenges as everywhere: Demographic chane, structural changes in agriculture and in small industries and trade, global climate change, and the requirements of the intended energy turnaround. This requires regional solutions. The contribution outlines the research project 'Integrative potential analysis for renewable energy sources' (ERNEUERBAR KOMM.) led by Prof. Dr. Klaerle (Ms.). Currently, the Mittelfranken regional development authority is carrying out two potential analyses in 12 communities, and five more regions with a total of 40 communities intend to participate as well.

    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.

    Technological innovations in the fields of renewable energy and energy efficiency are an essential basis of the global energy system transformation and act with appropriate implementation as value creation engine. The size and substantial growth of international markets for energy technologies and systems makes the positioning of German companies in these markets therefore become a topic of very far-reaching economic policy relevance. Hence the question of how Germany can benefit from a consistent implementation of the energy transition and its associated pioneering role in the international markets for energy technologies. [German] Technologische Innovationen in den Bereichen erneuerbare Energien und Energieeffizienz bilden eine wesentliche Grundlage der weltweiten Energiesystemtransformation und wirken bei geeigneter Implementierung als Wertschoepfungsmotor. Die Groesse und erhebliche Wachstumsdynamik der internationalen Maerkte fuer Energietechnologien und Systeme macht die Positionierung deutscher Unternehmen auf diesen Maerkten daher zu einem Thema von sehr weitreichender wirtschaftspolitischer Relevanz. Daraus ergibt sich die Frage, wie Deutschland von einer konsequenten Umsetzung der Energiewende und seiner damit verbundenen Vorreiterfunktion auf den internationalen Maerkten fuer Energietechnologien profitieren kann.

Darueber hinaus schaetzte ca. ein Viertel der Haushalte, die eine solarthermische Anlage installierten, den Einfluss der Kampagne eher hoch ein. Allerdings vermissten die Haushalte zum Teil weiterfuehrende Informationen. Auch die befragten Handwerker aeusserten eine relativ grosse Zufriedenheit mit der Kampagne. Sie nutzten die bereitgestellten Informationsmaterialien der Kampagne jedoch nur sehr selten. Die Evaluation der internen Grundlagen und Prozesse fuehrt zu ambivalenten Ergebnissen: Beispielsweise ist es der Kampagne auf der einen Seite gelungen, eine breite und heterogene Traegerschaft zu gewinnen und flexibel auf aeussere Anforderungen zu reagieren. Auf der anderen Seite stellten sich Probleme in der Steuerung und im Konfliktmanagement ein. Hierzu trugen u.a. eine nicht ausreichend integrierte Projektplanung sowie strukturelle Unterschiede zwischen den Partnern bei. Die Evaluation muendet in der zentralen Empfehlung, die Kampagne in modififizierter Form fortzusetzen. Verbesserungsmoeglichkeiten sehen die Evaluatoren u.a. in der verstaerkten Einbindung regionaler Aktvitaeten.

    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.

    Quota systems for the promotion of renewable energy sources are inferior to the reimbursement rates such as the German Renewable Energy Law (EEG). The reimbursement rates have been proven to be efficient and effective. Therefore companies demand no dismissal of the EEG because a dismissal reduces the security of investment and thwarts the expansion of renewable energies.

    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 energy turnaround has triggered a reorganisation of the German energy supply system and in the process has given rise to a number of complex problems. The challenge at hand is to find the optimal route into an energy supply landscape based largely on renewable resources. This article investigates two scenarios of a sustainable future, one based on largely fluctuating resources and the other including controllable renewable sources as well as the use of storages. The author has found there to be substantial differences between these two paths.

    In this paper we address the issue of whether renewable energy sources can be integrated into power markets if the use of renewable energies is extended at the desired speed. Market integration means that renewable energy sources have to cover their full costs from revenues on competitive markets. In the first part of this paper, we evaluate the long-term revenues of intermittent renewable energy sources using a high resolution power market model. Considering the renewable targets of the German lead study of 2010, we show that due to the merit order effect, intermittent renewable energy sources, such as wind power and photovoltaic, cannot be financed through power markets alone, even if their full costs fall below those of conventional power plants. This is also true for scenarios with high CO{sub 2}-prices and increasing spot market prices. In the second part of this paper, we discuss whether in the long run additional instruments such as green certificates or capacity markets would allow for a more competitive financing of renewable energy sources. Center stage in the discussion is the question under which circumstances these instruments increase competitive pricing and decentralised market decisions. (orig.)

    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

    The review under consideration reports on the acceptance and citizen participation in renewable energies. First of all, the authors define the term acceptance and describe the process of how this term is developed. Subsequently, the authors use the results of a representative survey by TNS Infratest (Munich, Federal Republic of Germany) in order to describe the peculiarity of the technology-specific acceptance of renewable energies in Germany. The facility-related acceptance of renewable energies is described in conjunction with the question whether there is a so-called NIMBY (Not in my backyard effect). Acceptable solutions for the problems of acceptance are presented based on two best practice examples by means of different procedures of the citizen's participation.

    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'

    In accordance with the operating principles, the Nordostschweizerische Kraftwerke (NOK) has decided on a comprehensive programme dedicated to opening up new sources of renewable energy and also to reducing demand by means of efficient power consumption. Intensive promotion, testing and information should ensure that, on the one hand, a premature condemnation of both possibilities and, on the other hand, exaggerated hopes can be avoided. (orig.).

    Electricity feed-in tariffs modelled on Germany's renewable energy law are giving impulses for growth and development in many other countries. However, the successes achieved with this concept should not mislead one into thinking that electricity feed-in laws are a universal promotion instrument that can be adapted to the situation of any country. Taking as an example the promotion scheme adopted in Brazil, a rising threshold country, it can be shown that there are alternative instruments for utilising the continuing cost decline to dynamise the market.

    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.

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. For the organizational- and project-success, however, the choice of investment volume

    Consumers of electricity pay for production, transport and distribution as well as for taxes and dues. Electricity rates depend on various influencing factors, e.g. different fuel and capital cost of the power plants and the ratio of supply and demand in the electricity stock markets. End user electricity rats also include taxes and dues as well as the cost of power transmission. The publication presents background information on the formation of electricity rates in Germany. In a second step, the different cost factors of fossil fuels, nuclear power and renewable energy sources are compared. In particular, the external cost is gone into which often tends to be neglected in the electricity markets.

    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 expansion of renewable energies is a central pillar of the energy transition. The development is positive: In 2016, renewable energies accounted for 31.7 percent of total gross electricity consumption. The brochure informs about the progress achieved in the further development of renewable energies in Germany, Europe and the world. The data on the development of renewable energies in Germany is based on the results of the Working Group on Renewable Energy Statistics (AGEE-Stat), which compiles the balance sheet of renewable energies for Germany on behalf of the BMWi. The data published here are a snapshot with the editorial deadline of August 2016 - they are still provisional in some places, especially for 2016. At the same time, current time series on the development of renewable energies in Germany since 1990 as well as a variety of graphs are published on the websites of the BMWi. These time series and graphs will be updated at the turn of the year 2017/2018. [German] Der Ausbau der erneuerbaren Energien ist eine zentrale Saeule der Energiewende. Die Entwicklung ist positiv: Im Jahr 2016 hatten die erneuerbare Energien einen Anteil von 31,7 Prozent am gesamten Bruttostromverbrauch.

    With the help of a sustainable power production, local bio energy projects connect ecological, economic and social solutions for the climate protection and the environment protection, for the support of the agriculture and forestry as well as for living together in the rural area. Past investigations concern primarily consider the collective commitment and the effects of such projects on the population. Under this aspect, the contribution under consideration is occupied with the acting of the initiators of the bio energy projects during the management of their tasks: Which conditions and motives of the initiators affect the conversion process? Under which conditions do the initiators arrive their goal? Which cognitive abilities, strategies of motivation and experiences particularly are important? For the qualitative investigation of these questions, five initiators of German local bio energy projects were interviewed. The results of these interviews are presented by means of paradigm models. It could be shown that both the person of the initiator and the relation of the person to the environment crucially contribute to the conversion of local bio energy projects.

    This work addresses the question of whether the ongoing transformation to a low-carbon energy system in Germany will also create market opportunities for innovative market participants, in particular for storage operators. The economic effects that occur in energy systems with high levels of variable renewable energy (vEE) can be measured by their integration costs. Scientific research into the additional storage and flexibility needs of such an energy system often addresses imbalances in the system balance sheet. The respective methods are, however, based on different assumptions and framework conditions, so that the results can only be compared with one another to a limited extent. The hourly fluctuating wholesale price on the electricity exchange is an important indicator to signal the need for flexibility. Many analyzes use historical or predicted pricing time series to evaluate storage options. However, while the feedback of the operation of an energy storage on the market prices is left out. Therefore, a method is developed in this work to estimate the impact of an increasing market volume of storage and other flexibility options on spot market prices. The influence of storage use on electricity demand and spot market prices in 2020 and 2030 is examined. The scenarios to be defined for the electricity market are model-based and evaluated. To answer the question, techno-economic models, e.g. The MICOES power market model for power plant deployment planning, the DeSiflex model for smoothing residual load through integrated flexibility options and the Arturflex model for estimating arbitrage gains through the use of flexibility options on the spot market.

    Policy strategies for the promotion of electricity from renewable energy sources differ significantly among the Member States of the European Union with respect to the amount of additional installed capacity as well as concerning the country-specific support costs. The present report aims to assess the effectiveness and the economic efficiency of the support policies in the EU based on both historical experiences and prospective model-based analysis. The main message of the investigation is that the most effective policy instruments tend to be cost-efficient at the same time. In particular, feed-in tariff systems were identified as a successful instrument for supporting renewable energies in terms of effectiveness and efficiency, whereas quota systems still have to prove themselves in practice. (orig.) [German] Bezueglich des Erfolges bei der Foerderung erneuerbarer Energietraeger im Stromsektor bestehen deutliche Unterschiede zwischen den Mitgliedsstaaten der Europaeischen Union. Dies betrifft sowohl den Zubau an installierter Kapazitaet als auch die laenderspezifischen Foerderkosten des Ausbaus. In diesem Projekt erfolgte eine vergleichende Betrachtung der Wirksamkeit und der oekonomischen Effizienz der Foerderpolitiken in den Laendern der EU basierend auf historischen Erfahrungen als auch auf prospektiven modellbasierten Analysen. Es zeigt sich, dass die wirksamsten Systeme auch haeufig die kostenguenstigsten sind. Insbesondere wird ersichtlich, dass garantierte Einspeisetarife ein sehr erfolgreiches Instrumentarium zur Foerderung erneuerbarer Energien im Stromsektor darstellen, nicht allein bezueglich des generierten Marktwachstums sondern auch im Hinblick auf die oekonomische Effizienz, wogegen Quotensysteme ihre Praxistauglichkeit bezogen auf die genannten Kriterien noch nachweisen muessen.

    In the First Technical Report the fundamental ideas for the realization of this project are presented and the future possible maximum gross employment effects of an expansion of renewable energy systems in North-Rhine-Westphalia with consideration of the present-day cost structure are quantified in an initial stage. In this connection gross employment effects are defined as exclusive positive job effects without consideration of possible negative employment effects on the basis of less investments in other sectors of the economy. Based on a subdivided presentation of the intended course of the project and a formulation of its main objectives, a detailed description of the theoretical background of the applied methods of input-output analysis is provided. After the presentation of some different methods and the necessary assumptions, the analysis takes the so-called `Keynesian income multiplier` into account to accommodate the effects of an increase in national income. To use a known investment distribution, grouped in 21 sub-divisions according to categories of applications, within the scope of an input-output-analysis, the investments are converted. After the determination of the matrices, necessary to quantify employment effects, the maximum possible gross effects concerning the future job market of the Federal Republic of Germany will be assessed with consideration of the fluctuations in productivity on sector level. A total of 700.000 new jobs can be expected, of which about 27% are due to the increase of personal disposable income and the resulting rise in consumer spending respectively.

    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

    A core component of the German government's Energy Concept is the expansion of electricity production from renewable energies. The German government also decided to decommission or not reactivate eight nuclear power plants following the nuclear catastrophe in Fukushima. For the outstanding reactors in Germany it determined shorter remaining lifetimes. As a result electricity production in Germany is facing extensive transformation. The feed-in of renewable energies influence power plant dispatch and thereby also the electricity price. Since renewable energies are supported by a set price for their feed-in, their production occurs independently of demand with the result that the electricity price on the spot markets falls. Similarly the electricity price on the spot markets is lower in the case of the lifetime extension of nuclear power plants than without such an extension as a result of the low marginal costs of such plants. Moreover an increased feed-in of renewable energies or the lifetime extension of nuclear power plants leads to a lower electricity production in other conventional (fossil) power plants. This has an impact on the dispatch of power plants and the long-term development of the power plant fleet (arising from decommissioned plants and new investments). A lower electricity price, fewer operating hours for fossil power plants and a lifetime extension for nuclear power plants can lead to the profitable operation of fossil power plants no longer being possible and such plants being either decommissioned or mothballed. Similarly, comparatively higher electricity prices resulting from a quicker phase-out of nuclear energy can lead to an improvement in profitability and thereby also a reactivation of mothballed power plants or the retrofitting of fossil power plants. In this research project an iterative consideration of the short-term dispatch of power plants in a dispatch model and of the long-term decommissioning and investment effects in a power

    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 its broad system approach, dena Grid Study II describes new ways of developing Germany's integrated grid with regard to the expansion of renewable energy sources and taking not only an economically optimised conventional power generation system but also European power trading into account. Basis for detailed grid planning. Having investigated many different transmission technologies, grid management measures and options for increasing flexibility on both the supply and demand side, the study does much more than simply identify grid expansion requirements, it shows the path towards overall optimisation of the energy supply system. In addition to robustly identifying grid expansion requirements, dena Grid Study II provides a very sound basis for further detailed grid planning and the identification of specific power routes in the German power transmission grid. Increasing grid expansion requirements. dena Grid Study II investigates the expansion of electricity generation from renewable energy sources to 39 percent by 2020. However, this is just an interim goal. By as soon as 2030, the German Federal Government is planning to raise the proportion of renewable electricity generation to 50 percent. This shows that even after 2020, further adaptation of grid infrastructure will still be necessary. Practical action required. If the grid expansion required to integrate renewable energy sources is to be achieved rapidly, there is an urgent need to back up the grid expansion scenarios presented in dena Grid Study II with practical action.

    In Switzerland, poor energy efficiency costs yearly about 12 billions CHF or 1700 CHF per inhabitant. More news: if renewable energies (solar and wind energy, biomass) would be promoted with concrete targets, job creation balance would result in the positive result of about 63,000 new jobs. These are conclusions from an economic study by Professor Ernst von Weizsaecker, ordered by the association 'Solar 91'. This confirms the energy policy adopted by the Swiss Association of air conditioning companies 'Clima Suisse'.

    Throughout Europe the energy economy faces two major challenges from new governmental regulation, namely regulation for the purposes of climate policy and regulation for the introduction of competition to what used to be monopolistic sectors. With regard to the growing regulatory influence of the European Union the author of this British-German comparative study analyses how diverging structures of governmental organisation and historical paths of development have led to different regulatory approaches to the market introduction of renewable energies and the liberalisation of the power economy. He offers an in-depth analysis of the differences in success the two countries success have had in developing sustainable electricity production systems and establishing competitive structures in the power sector.

    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 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 PhD thesis develops a stochastic model to explain pricing in Quota Obligation schemes for renewable energy (RE). It is based on the fact that electricity production from RE is depending on weather and other conditions, which leads to a random fluctuation. In the developed model the price for RE is depending on the probability of a lack of certificates at the end of an obligation period. In contrast to deterministic models, the stochastic model has a direct link between the price for RE and their high investment costs. Moreover, the stochastic model can be used to describe the development of prices over an obligation period. The model is adopted to the Swedish quota obligation. It is shown that the real RE prices there are much higher than the estimated prices derived from the model. This result is consistent to the fact that installed RE capacity in Sweden is much higher than necessary to fulfill the quota obligation.

    The inspiration for the design of an energy system of the future constitutes the necessary change of the power generation structure deriving from renewable energy sources such as wind power and solar energy. In Germany, the captured feeding volume of renewable energy amounts 89.1 TWh per annum in 2009. The high demands on a stable and efficient network operation require an intelligent networking of information and communication technology. This network enables the production facilities and consumption components to communicate with renewable energies. EWE AG (Oldenburg, Federal Republic of Germany) develops and implements an active smart grid as a distribution network with a virtual power plants and energy marketplaces, with network services and management algorithms and a new tariff system feedback sysem for the involvement of domestic consumers.

    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 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

    Regions with a large proportion of renewable energies offer particularly good prerequisites for testing out future decentralised supply systems. In the rural district of Harz, one of six model regions in the German government's E-Energy programme, more than 20 partners from various sectors of the electricity industry have developed technologies and business models for smart grids. Four municipal utility companies and two distribution network operators were involved in their implementation. The four-year RegModHarz research project, which is funded by the German Federal Ministry for the Environment, will be completed at the beginning of 2013. (orig.)

    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 application of innovative information technologies can make an important contribution to meet new requirements in many fields. Portal, content, management and integration technologies and new technologies for the web-based and mobile access to information are only a few of these. Development and conservation of the new information and communication systems mostly involve high costs. Increasingly, the funds required cannot be provided by the instances involved which is due to the scarce funds available in the public budgets. Individual developments, on the other hand, would not correspond with requirements of effective using and careful employment of the funds. One important tool which territorial authorities can use in order to meet these challenges is increased cooperation in developing and conserving information systems. In order to support the cooperation within the State of Baden-Wuerttemberg and also with the Federal Government and the other States, the R and D-project AJA (Application of JAVA-based and other efficient solutions in the areas of environment, traffic and administration) was created at the end of 1999.

    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.

    The conversion of energy supply based on renewable energies will be electricity based and the efficient provision of heating and cooling can be done by electric heat pumps. In cities, however, where the open areas for geothermal systems are scarce, groundwater-based systems can be a powerful option. The development of a large heat reservoir via a single bore is possible with vertical groundwater circulation systems and is described here. [German] Der Umbau der Energieversorgung auf erneuerbare Energien wird Strom basiert sein und eine effiziente Bereitstellung von Waerme und Kaelte kann durch elektrische Waermepumpen erfolgen. Innerstaedtisch sind die Freiflaechen fuer Geothermieanlagen allerdings knapp, so dass Grundwasser basierte Anlagen eine leistungsfaehige Option darstellen koennen. Die Erschliessung eines grossen Waerme-Reservoirs ueber nur eine Bohrung ist mit vertikalen Grundwasserzirkulationsanlagen moeglich und wird hier beschrieben.

    Aim: After the nuclear disaster at Fukushima in 2011, Germany decided to phase out atomic energy, without producing new CO 2 emissions. The article discusses the promotion systems that are used. Scope: The percentage of renewable energies in Germany's electricity consumption increased from 3 in 1990 to 23 in 2012. This development was introduced and guided by a law called Renewable Energy Sources Act. It guarantees a privileged acceptance of electricity and a fixed gratification for 20 years to the operators of regenerative power plants. It allows the operators to install regenerative power plants at a reduced risk. By contrast, the international means for CO 2 reduction is the trading of emission certificates, which is also valid for Germany. The article discusses how the promotion of the Erneuerbar-Energien-Gesetz (EEG) and other plant-based promotion systems fit into this condition. It also elucidates the actual decline of promotion, its problems to the country’s environmental economy and the approach of decentralized photovoltaic (PV) energy plants towards economical efficiency. Conclusions: Germany’s energy turnaround to a regenerative energy supply is characterized by a strong and differentiated promotion system. Substantial efforts have to be made as the percentage of the renewable energy sources has significantly increased but is still under 25%

    Hydrogen and fuel cells have great potential and are currently at the threshold of commercialization. Baden-Wuerttemberg and German companies and research institutions have created a good starting point for participating in these growth markets internationally. With dwindling fossil resources, the phasing out of nuclear energy and international targets for reducing greenhouse gas emissions, the entire energy system is fundamentally changing and will be fully converted over the long term to renewable energy sources. While in the past chemical sources of energy dominated as the primary source of energy, in the future these will be superseded in particular by electricity as a renewable, largely fluctuating primary energy. At the same time, however, the easy storage and transportability of energy is also partially lost. An intelligent combination of electricity, gas (methane, hydrogen), heat and fuels for mobility is a prerequisite for a robust, sustainable and sustainable energy supply in Germany. The coordinated interaction between generation, transmission, distribution, storage and consumption of electrical energy enables the efficient integration of renewable energies into the energy supply system and a secure transition to the regenerative energy age. Germany needs a robust and flexible energy strategy that can provide long-term planning security for all market players. [German] Wasserstoff und Brennstoffzellen haben ein grosses Potenzial und stehen derzeit an der Schwelle der Kommerzialisierung. Baden-wuerttembergische und deutsche Unternehmen und Forschungseinrichtungen haben sich eine gute Ausgangsbasis geschaffen, um international an diesen Wachstumsmaerkten zu partizipieren. Mit knapper werdenden fossilen Ressourcen, dem Ausstieg aus der Kernenergie und den internationalen Zielen zur Verringerung von Treibhausgasemissionen aendert sich das gesamte Energiesystem fundamental und wird langfristig vollstaendig auf erneuerbare Energietraeger umgestellt

    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.

    The expansion of electricity generation from renewable sources in Germany is promoted by the Erneuerbare-Energien-Gesetz (EEG), which was last amended in June 2008. In a review of the EEG the political parameters, the progress achieved, and the impacts of the Act itself are set out. This Progress Report addresses cross-sectoral aspects, notably CO 2 emissions reduction, job creation, investment and turnover in the renewables industry, and that industry's prospects for the future. Trends in the individual renewables sectors are described and policy recommendations formulated, as appropriate, on this basis. The policy recommendations have been incorporated into the new EEG from 6 June 2008. The overarching goal of the new EEG is to achieve a renewables share of at least 30% in Germany's electricity consumption in 2020. This underlines the need for radical modernisation of the energy system as a whole. This article presents an overview of the content of the Progress Report and supplements it with current statistical data and research findings contained in other publications from the Federal Ministry for the Environment (BMU). It also highlights the points on which the new EEG diverges from the policy recommendations contained in the Progress Report.

    In the long term, the sector coupling will convert other areas of consumption such as heat and transport to purely renewable energy sources. A model-based analysis of system costs across all stages of the value chain shows that the existing gas infrastructure in particular can make an important contribution to achieving a comprehensive energy turnaround at low cost. Preserving the gas networks in connection with the use of green gas as a further end energy carrier in addition to electricity leads to significantly lower overall costs than a comprehensive electrification of all end applications. This can also help overcome acceptance problems. [German] Mit der Sektorkopplung werden langfristig weitere Verbrauchsbereiche wie Waerme und Verkehr auf rein erneuerbare Energiequellen umgestellt. Eine modellgestuetzte Analyse der Systemkosten ueber alle Wertschoepfungsstufen hinweg zeigt, dass insbesondere die vorhandene Gasinfrastruktur einen wichtigen Beitrag leisten kann, eine umfassende Energiewende kostenguenstig zu erreichen. Ein Erhalt der Gasnetze in Verbindung mit der Nutzung von Gruenem Gas als weiterem Endenergietraeger neben Strom fuehrt zu deutlich niedrigeren Gesamtkosten als eine umfassende Elektrifizierung aller Endanwendungen. Zudem kann dies helfen, Akzeptanzprobleme zu ueberwinden.

    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.

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.

    The book investigates the acceptance of wind power in Austria, especially in the state of Burgenland where most wind power systems are sited. It starts by providing an analysis of the electric power industry as it is and then proceeds to compare the situation with other EU member states, especially Germany and Denmark which are leading in wind power. The results of the enquiry concerning social acceptance are presented and recommendations for action are presented. It was found that social acceptance of wind power systems in Austria is quite high even though the population providing the answers have to see them all the time. The book addresses all those who are faced with the prospect of having wind power systems constructed in their vicinity, as well as scientists and industrial organisations. (orig.)

    The energy transition - the conversion of our power supply to so-called ''Renewable Energy'' - will lead to disaster, economically as well as technically. Although the concept is not technically feasible, more than 500 billion Euros were spent for this purpose already. This money our economy will miss bitterly when it is needed it to go, sweep up the future shambles. Here explain two recognized experts why. ''The book, 'electric power is not the same power' pulled himself together again on a colossal effort. It dissects technically brilliant with the tools of logic, scientific reasoning a fatal mental aberration.''- Arnold Vaatz MP. [German] Die Energiewende - die Umstellung unserer Stromversorgung auf sogenannte ''Erneuerbare Energien'' - wird in eine Katastrophe fuehren, wirtschaftlich ebenso wie technisch. Obwohl das Konzept technisch nicht machbar ist, wurden hierfuer bereits mehr als 500 Milliarden Euro ausgegeben. Dieses Geld wird unserer Volkswirtschaft bitter fehlen, wenn sie darangehen muss, den kuenftigen Scherbenhaufen zusammenzukehren. Hier erklaeren zwei ausgewiesene Fachleute, warum. ''Das Buch 'Strom ist nicht gleich Strom' rafft sich noch einmal zu einer ungeheuren Kraftanstrengung auf. Es seziert handwerklich brillant mit den Mitteln der logischen, naturwissenschaftlichen Argumentation einen fatalen geistigen Irrweg.'' - Arnold Vaatz MdB.

    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.) [Deutsch] Im Rahmen einer von der Stiftung Energieforschung Baden-Wuerttemberg gefoerderten Neuentwicklung wurde eine Axialturbine als Entspannungsturbine entwickelt, mit der eine Energierueckgewinnung in allen Bereichen erfolgen kann, in denen Fluessigkeiten in Rohrleitungssystemen entspannt werden. Die Turbine zeichnet sich unter anderem dadurch aus, dass sie komplett, inklusive Generator, innerhalb einer Rohrleitung angeordnet ist und bei Netzausfall keine nennenswerte Druckschwankung erzeugt. Es werden die Turbine, deren Vorteile sowie der mit einem Prototypen durchgefuehrte Betriebsversuch beschrieben. Weiterhin werden ein Vergleich des Betriebsverhaltens mit einer rueckwaertslaufenden Pumpe, die rechnerische Optimierung der hydraulischen Formgebung sowie die Ergebnisse einer Marktanalyse behandelt.

    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.)

    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.

    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.

    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.

    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. In Hamburg gibt es seit rd. 10 Jahren verschiedene Pilotprojekte, die sich insbesondere mit Fragen der Infrastruktur zur Integration erneuerbarer Energiequellen in die bestehende Energieversorgung befassen. 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.

    A review is made about the consequences of the European directive on energy that entered into application in august 2000. It appears that most countries are opening their electricity and gas markets at a faster pace than required by the E.U. directive. European gas imports reached 480 Gm{sup 3} in 2000 and are expected to be over 700 Gm{sup 3} in 2015, so the question of the reliability of the gas suppliers has to be answered at the European level. The current time is marked by an increase of the complexity of the energy market that is due to different factors: 1) the delay in the implementation of European energy directives in France, 2) new arrangement is occurring in United-Kingdom in the energy sector, 3) the lack of a regulating authority in Germany, and 4) the difficulty of inter-connecting the different European energy networks. This transitory period may generate some economic imbalances and competition disturbances by allowing some enterprises to benefit from lower energy prices before others. (A.C.)

    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.

Daraus entstehen neue Herausforderungen. Zu deren Bewaeltigung hat das Bundeswirtschaftsministerium (BMWi) kuerzlich eine 10-Punkte-Agenda (ZPA) fuer die zentralen Vorhaben der Energiewende vorgelegt.

    For a long time, natural gas was considered as an ideal bridge technology for the energy transition because of the relatively low CO{sub 2} content. With increasing decarbonisation of electricity generation by renewable energies and the associated political vision of a far-reaching electrification of energy applications, in particular in the heat sector, the gas sector is, however, threatened to be overtaken by the renewables. This creates increasing uncertainty for business models and investments in the natural gas sector itself, but also potentially high macroeconomic costs of the energy transition. It can be shown that such a development is not unavoidable if the gas sector succeeds in using the existing possibilities cleverly. Thereby the continued use of existing gas infrastructure plays a central role. For use of the opportunities, however, a paradigm shift in politics, regulation and natural gas sector is necessary, whose key points are developed in this article. [German] Lange wurde Gas aufgrund des relativ geringen C0{sub 2}-Gehalts als ideale Brueckentechnologie fuer die Energiewende gehandelt. Mit zunehmender Dekarbonisierung der Stromerzeugung durch erneuerbare Energien und der damit verbundenen politischen Vision einer weitreichenden Elektrifizierung von Energieanwendungen insbesondere im Waermesektor droht die Gaswirtschaft allerdings von den Erneuerbaren ueberholt zu werden. Das schafft zunehmende Unsicherheit fuer Geschaeftsmodelle und Investitionen im Gassektor selbst, aber auch potenziell hohe gesamtwirtschaftliche Kosten der Energiewende. Es laesst sich zeigen, dass eine solche Entwicklung nicht unabwendbar ist, wenn es der Gaswirtschaft gelingt, die vorhandenen Moeglichkeiten clever zu nutzen. Dabei spielt der fortgesetzte Gebrauch der bereits vorhandenen Gasinfrastruktur die zentrale Rolle. Zur Nutzung der Chancen ist aber ein Paradigmenwechsel in Politik, Regulierung und Gaswirtschaft notwendig, dessen Eckpunkte in diesem Artikel entwickelt

    Die Übertragungsnetze stellen eine zuverlässige Versorgung von Haushalt, Gewerbe und Industrie mit elektrischer Energie sicher und sind damit Grundlage einer modernen Wirtschaft und Gesellschaft. Die mittlerweile unumkehrbaren Entwicklungen der nationalen und europäischen Energiewende stellen den Übertragungsnetzbetreiber in seinen Kernaufgaben, dem Bau und Betrieb von Netzen, dem Markt- und Netzzugang und der Integration der erneuerbaren Energien vor neue und große Herausforderungen. Verbrauchsnahe dezentrale Erzeugung wie verbrauchsferne zentrale Erzeugung muss im Sinne der Gewährleistung der Systemstabilität gemanagt und in Einklang mit dem Verbrauch gebracht werden. Erneuerbare Energien müssen zudem in einem solchen System ihren Beitrag zur System- und Marktintegration leisten. All das erfordert mehr Daten, um in einem Gesamtsystem dynamische Reaktionsmöglichkeiten gewährleisten zu können. Erst die "Digitalisierung" schafft dabei die notwendigen Voraussetzungen die Komplexität zu stemmen. Die Digitalisierung stellt daher ein Kernelement dieses Wandels des Übertragungsnetzbetreibers dar, die einerseits mit zum Entstehen der neuen Herausforderungen beiträgt, andererseits aber auch hilft Werkzeuge bereitzustellen, diesen Herausforderungen zu begegnen. Im folgenden Beitrag wird aufgezeigt, wie die Digitalisierung die Aufgaben und Instrumente des Übertragungsnetzbetreibers verändern. Ausgehend von den heutigen Aufgaben eines Übertragungsnetzbetreibers und dem gültigen Rechtsrahmen werden unter dem Begriff "Notwendiges Set für morgen" smarte Elemente und Werkzeuge beschrieben, die bereits heute im Einsatz sind oder in den nächsten Jahren notwendig werden. Im Anschluss erfolgt anhand einiger Beispiele aus unterschiedlichen Bereichen eine Konkretisierung der Einsatzzwecke der Digitalisierung beim Übertragungsnetzbetreiber. Ein kurzer Ausblick mit Fokus auf den weiteren Veränderungsprozess rundet den Beitrag ab.

    The term of the energy transition will not be translated as it travels around the world. He points to the urgency of the conversion of the energy supply for electricity, heat and mobility through renewable energies. Faster than many had expected the energy revolution has reached a pace of expansion, especially in the electricity sector, which many did not expect. However, it is not a voluntary measure, but is forced by the proneness of unsustainable production methods and lifestyles. It is also not a foregone conclusion. The many new initiatives, policies and programs are in competition with an old, fossil and nuclear energy system. From the hurdles that have already been taken in this race, the pace of expansion, innovation as well as the necessary reforms and diverse challenges of the energy transition, this book is dealing. [German] Der Begriff der Energiewende wird bei seinem Lauf um die Welt nicht uebersetzt. Er weist auf die Dringlichkeit der Umstellung der Energieversorgung bei Strom, Waerme und Mobilitaet durch erneuerbare Energien hin. Schneller als von vielen erwartet hat die Energiewende vor allem im Strombereich ein Ausbautempo erreicht, mit dem viele nicht gerechnet hatten. Sie ist allerdings keine freiwillige Massnahme, sondern wird durch die Krisenhaftigkeit von nicht nachhaltigen Produktions- und Lebensweisen erzwungen. Sie ist auch kein Selbstlaeufer. Die vielfaeltigen neuen Initiativen, Massnahmen und Programme befinden sich im Wettbewerb mit einem alten, fossilen und nuklearen Energiesystem. Von den Huerden, die in diesem Wettlauf bereits genommen wurden, vom Tempo des Ausbaus, von Innovationen sowie von den notwendigen Reformen und vielfaeltigen Herausforderungen der Energiewende handelt dieses Buch.

    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.

    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

There one drives innovation and investments with the objective of fulfilling by 2050 their own needs completely by renewable sources.

If successful, the region would be on climate protection well ahead of the national targets, the 2050 ''only'' provide a CO{sub 2} emission reduction of 75%. In addition to the Research and development (R and D) to many future ideas in Hauts-de-France but also some major projects for Security of European energy supplies are realized that show the local agility.

Die Orientierung dazu liefert Jeremy Rifkins Idee der dritten industriellen Revolution. Im Erfolgsfall laege die Region beim Klimaschutz deutlich vor den nationalen Zielen, die bis 2050 ''nur'' eine CO{sub 2}-Emissionsreduktion von 75 % vorsehen. Neben der Forschung und Entwicklung (F and E) zu vielen Zukunftsideen werden in Hauts-de-France aber auch einige Grossprojekte zur Absicherung der europaeischen Energieversorgung realisiert, die Ausweis der dortigen Agilitaet sind.

    The decarbonisation of the energy and, above all, the power system is the core component of any consistent climate protection strategy. For the electricity sector, this means, in the final analysis, the transition from a power supply based on lignite, hard coal, natural gas and other fossil fuels to one (almost) completely based on renewable energies by 2050. The fundamental technical feasibility of such a system, more than 90 percent of which would generate electricity from renewable energies, is no longer disputable today. The explanation for this is the partly rapid technological advances made in recent years, particularly those involving wind (on- and offshore) and solar energy, as well as the foreseeable further developments of central flexibility options (including flexible demand, battery storage and power-to-gas technologies). However, the question of the costs of this new electricity system has not yet been fully resolved. These cost calculations need to take into account, on the one hand, the total costs of an electricity system based on renewable energies and, on the other hand, the comparison to a power system that remains based on fossil fuels. Against this background, the present study provides a numerical analysis of the following questions: What are the technical and cost structures for a power system when 90 percent or more of the electricity is generated from renewable energies in 2050? How do the costs for different storage strategies (batteries vs. power-to-gas) differ? What technical, cost and emission structures result for a hypothetical fossil-based power system in 2050 if the further construction of electricity production plants based on wind and solar energy is immediately abandoned? How do the costs for various fossil-based power systems differ (conventional mix of lignite/hard coal/natural gas power plants vs. an electricity system based purely on natural gas)? For this purpose, a large number of model calculations with different

    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

    .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.

    1974-01-01

    The Detroit Energy Conference has highlighted the declining oil reserves, estimated worldwide at 95 billion tons vs. an annual rate of consumption of over 3 billion tons. The present problem is one of price; also, petroleum seems too valuable to be simply burned. New sources must come into action before 1985. The most abundant is coal, with 600 billion tons of easily recoverable reserves; then comes oil shale with a potential of 400 billion tons of oil. Exploitation at the rate of 55 go 140 million tons/yr is planned in the U.S. after 1985. More exotic and impossible to estimate quantitatively are such sources as wind, tides, and the thermal energy of the oceans--these are probably far in the future. The same is true of solar and geothermal energy in large amounts. The only other realistic energy source is nuclear energy: the European Economic Community looks forward to covering 60% of its energy needs from nuclear energy in the year 2000. Even today, from 400 mw upward, a nuclear generating plant is more economical than a fossil fueled one. Conservation will become the byword, and profound changes in society are to be expected.

    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.

    1981-01-01

    During the early 1960s, a plentiful, inexpensive supply of petroleum enabled Japanese industry to progress rapidly; however, almost all of this petroleum was imported. Even after the first oil crisis of 1973, the recent annual energy consumption of Japan is calculated to be about 360 million tons in terms of petroleum, and actual petroleum forms 73% of total energy. It is necessary for Japan to reduce reliance on petroleum and to diversify energy resources. The use of other fossil fuels, such as coal, LNG and LPG, and hydraulic energy, is considered as an established alternative. In this presentation, the author deals with new energy, namely soft energy and nuclear energy, and discusses their characteristics and problems. The following kinds of energy are dealt with: a) Solar energy, b) Geothermal energy, c) Ocean energy (tidal, thermal, wave), d) Wind energy, e) Biomass energy, f) Hydrogen, g) Nuclear (thermal, fast, fusion). To solve the energy problem in future, assiduous efforts should be made to develop new energy systems. Among them, the most promising alternative energy is nuclear energy, and various kinds of thermal reactor systems have been developed for practical application. As a solution to the long-term future energy problem, research on and development of fast breeder reactors and fusion reactors are going on. (author)

    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.

    Do Georgia needs nuclear energy? Nuclear energy is high technology and application of such technology needs definite level of industry, science and society development. Nuclear energy is not only source of electricity production - application of nuclear energy increases year-by-year for medical, science and industrial use. As an energy source Georgia has priority to extend hydro-power capacity by reasonable use of all available water resources. In parallel regime the application of energy efficiency and energy conservation measures should be considered but currently this is not prioritized by Government. Meanwhile this should be taken into consideration that attempts to reduce energy consumption by increasing energy efficiency would simply raise demand for energy in the economy as a whole. The Nuclear energy application needs routine calculation and investigation. For this reason Government Commission is already established. But it seems in advance that regional nuclear power plant for South-Caucasus region would be much more attractive for future

    Energy consumption has developed significantly since the Second World War and population growth and improved living standards should see needs increasing even more. Traditional forecasts show that this energy consumption will continue to depend heavily on fossil energy. However, resources are limited and their use have a negative impact on the greenhouse effect and climate change. There is therefore a need to develop large quantities of renewable energy sources, to intensify energy saving programs and to pursue research in certain key areas

    Today's less developed countries (LDCs) have access to energy technologies that did not exist when today's richer countries were at similar stages of development. Do LDCs therefore consume less energy per capita than rich countries in the past? And is their economic growth associated with a lower growth in energy consumption? Can they "leapfrog" to a lower-carbon economy? I use data on energy consumption, prices, and gross domestic product for 76 countries to estimate the energy intensity of ...

    Energy is an essential factor to economic and social development and improved standards of living in developing countries. Nigeria in particular. There is a strong need for greater energy efficiency in every sector of economy in order to reduce costs. enhance competitiveness, conserve energy resources and reduce environmental impacts associated with production, distribution and use of energy. Energy auditing and monitoring has a significant role in any energy management and conservation project. Energy auditing as an important part of industrial energy management on plant level, represents a complex of activities aiming at the efficient use of energy. The activities are undertaken by a team of experts who use a set of measuring instruments to monitor and evaluate all the necessary data to elaborate a package of recommendations on improvements in the field of energy efficiency and possible product quality. The inefficient conversion and use of energy have been identified as a central problem for all developing countries, Nigeria inclusive, since they all consume significantly higher amounts of energy per unit of GDP than OECD countries. This aggravates energy-related environmental problems and is also a burden on domestic resources and foreign exchange. Energy prices have risen drastically in many developing countries, while energy intensities remain high. Price changes alone are not rapidly translating energy efficiency improvements. Identifying and removing the obstacles to greater energy efficiency should be priority for government in developing countries. This is why the Energy Commission, an apex organ of government on Energy matters in all its ramifications is out to encourage relatively low-cost energy audits for the Textile industries - such audits can identify ''good house-keeping's' measures, such as simply process improvements, that reduce energy consumption and operating costs. This will be followed by the training of plant workers/energy managers

    In this book, the author aims at giving some explanations about the various terms regarding energy which are present in our everyday life, in speeches, in papers and magazines, on the air, in our energy bills, for instance: energy poverty, price of a barrel of oil, resources and proved reserves, intermittency and energy storage, fossil and renewable energies, and so on. In a first part, the author addresses issues ranging from the development needs of a society to the energy assessment of a country, i.e.: nature and quantity of needs in services provided by energy, analysis of the required quantity of energy products needed to satisfy these needs, stages between primary resources and service delivery, description of the French consumption of available final energy products (per product and per economic sector). In the second part, he addresses energy supply, energy sectors and environmental issues, thus focusing on the front end of the energy system, i.e. ways of production from primary energy resources to final energy products: main physical characteristics and description of the different fissile, fossil and renewable energies, description of the main sectors of production of final energy products (fuels, electricity, heat) with a specific attention to electricity. In this part, local, regional and global environmental issues related to the exploitation of these energy sectors are discussed: sources of atmospheric pollution related to energy, relationship between energy and global warming, role of the different greenhouse gases emitted by these sectors, and quantitative analysis of these emissions. The third part addresses the economy of energy systems. The author proposes a cost assessment method which can be used for the production analysis as well as the economic analysis of a specific energy product. He also described external costs and profits, and methods to take those hidden costs and profits into account. Other economic tools are discussed and compared

    Energy is necessary for any phenomenon to occur or any process to proceed. Nevertheless, energy is never consumed; instead, it is conserved. What is consumed is available energy, or exergy, accompanied by an increase in entropy. Obviously, the terminology, "energy consumption" is indeed a misnomer although it is ubiquitous in the…

    G.A. de Boer reacts to recently published criticism of his contribution to a report entitled 'Commentaar op het boek 'Tussen Kernenergie en Kolen. Een Analyse' van ir. J.W. Storm van Leeuwen' (Commentary on the book 'Nuclear Energy versus Coal. An Analysis by ir. J.W. Storm van Leeuwen), published by the Dutch Ministry of Economic Affairs. The contribution (Appendix B) deals with energy analyses. He justifies his arguments for using energy accountancy for assessing different methods of producing electricity, and explains that it is simply an alternative to purely economic methods. The energy conversion yield (ratio of energy produced to energy required) is tabulated for different sources. De Boer emphasises that his article purposely discusses among other things, definitions, forms of energy, the limits of the systems, the conversion of money into energy and the definition of the energy yield at length, in order to prevent misunderstandings.

    Renewable energy sources have a small environmental impact and can be easily integrated within existing structures. Moreover, the use of renewable energy sources can contribute to achieve a zero emission of carbon dioxide by 2100, provided an efficient environmental policy during the next 40 years. This includes a correct pricing policy of renewable energy sources with respect to nuclear energy and fossil fuel. The latter energy sources have been favoured in the past. In addition, an open market policy, the restructuring or conversion of existing international energy institutes, and international treaties for the protection of the natural environment are needed in view of achieving the zero carbon dioxide emission objective.

    Up to the present the production, transmission and distribution of energy has been considered mostly as a fragmented problem; at best only subsystems have been considered. Today the scale of energy utilization is increasing rapidly, and correspondingly, the reliance of societies on energy. Such strong quantitative increases influence the qualitative nature of energy utilization in most of its aspects. Resources, reserves, reliability and environment are among the key words that may characterize the change in the nature of the energy utilization problem. Energy can no longer be considered an isolated technical and economical problem, rather it is embedded in the ecosphere and the society-technology complex. Restraints and boundary conditions have to be taken into account with the same degree of attention as in traditional technical problems, for example a steam turbine. This results in a strong degree of interweaving. Further, the purpose of providing energy becomes more visible, that is, to make survival possible in a civilized and highly populated world on a finite globe. Because of such interweaving and finiteness it is felt that energy should be considered as a system and therefore the term 'energy systems' is used. The production of energy is only one component of such a system; the handling of energy and the embedding of energy into the global and social complex in terms of ecology, economy, risks and resources are of similar importance. he systems approach to the energy problem needs more explanation. This paper is meant to give an outline of the underlying problems and it is hoped that by so doing the wide range of sometimes confusing voices about energy can be better understood. Such confusion starts already with the term 'energy crisis'. Is there an energy crisis or not? Much future work is required to tackle the problems of energy systems.

    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.

  12. Energy infrastructure: hydrogen energy system

    Energy Technology Data Exchange (ETDEWEB)

    Veziroglu, T N

    1979-02-01

    In a hydrogen system, hydrogen is not a primary source of energy, but an intermediary, an energy carrier between the primary energy sources and the user. The new unconventional energy sources, such as nuclear breeder reactors, fusion reactors, direct solar radiation, wind energy, ocean thermal energy, and geothermal energy have their shortcomings. These shortcomings of the new sources point out to the need for an intermediary energy system to form the link between the primary energy sources and the user. In such a system, the intermediary energy form must be transportable and storable; economical to produce; and if possible renewable and pollution-free. The above prerequisites are best met by hydrogen. Hydrogen is plentiful in the form of water. It is the cheapest synthetic fuel to manufacture per unit of energy stored in it. It is the least polluting of all of the fuels, and is the lightest and recyclable. In the proposed system, hydrogen would be produced in large plants located away from the consumption centers at the sites where primary new energy sources and water are available. Hydrogen would then be transported to energy consumption centers where it would be used in every application where fossil fuels are being used today. Once such a system is established, it will never be necessary to change to any other energy system.

  13. Energy consumption and energy prices

    International Nuclear Information System (INIS)

    Bentzen, J.

    1993-01-01

    Data are presented on energy consumption and energy prices related to a number of OECD (Organisation for Economic Co-operation and Development) lands covering the period 1951-1990. The information sources are described and the development of energy consumption and prices in Denmark are illustrated in relation to these other countries. The energy intensity (the relation between energy consumption and the gross national product) is dealt with. Here it is possible to follow development during the whole post-war period. It is generally understood that Denmark saved large amounts of energy after 1973-74 but, taken over the whole post-war period, savings and decline in energy-gross national product relations are less dramatic compared to conditions in other OECD countries. Energy coefficients or elasticities show the relative rise in consumption compared to the relative rise in gross national product (growth rate). This is shown to be typically unstable and an eventual connection with the amount of energy price increase and/or the growth rate of the national economy is considered. Results of Granger causuality tests on energy consumption, national income and energy prices are presented. Effective energy prices were very low in Denmark up to 1970 when they suddenly began to increase. Since the oil crisis Denmark's energy consumption has fallen whereas the other countries have used rather more energy than before. Effective promotion of energy savings must be seen in relation to the fact that the 1970 basis level of energy consumption and intensity was unusually high. The high effective energy prices have also encouraged energy savings in Denmark. (AB)

    Today we know two forms of nuclear energy: fission and fusion. Fission is the decomposition of heavy nuclei, while fusion is the melting together of light nuclei. Both processes create a large surplus of energy. Technologically, we can currently only use fission to produce energy in today's nuclear power plants, but there is intense research worldwide in order to realize a controlled fusion process. In a practical context, today's nuclear energy is a sustained source of energy since the resource base is virtually unlimited. When fusion technology is realized, the resource supply will be a marginal problem. (AG)

    International Nuclear Information System (INIS)

    Davis, G.

    1991-01-01

    The possibility of energy catastrophes in the production of energy serves to make estimation of the true social costs of energy production difficult. As a result, there is a distinct possibility that the private marginal cost curve of energy producers lies to the left or right of the true cost curve. If so, social welfare will not be maximized, and underconsumption or overconsumption of fuels will exist. The occurrence of energy catastrophes and observance of the market reaction to these occurrences indicates that overconsumption of energy has been the case in the past. Postulations as to market reactions to further energy catastrophes lead to the presumption that energy consumption levels remain above those that are socially optimal

  11. Energy needs

    Maxey, M.N.

    1982-06-01

    There seems to be a trend towards expecting energy conservation to be a panacea for the world's ills. In fact, a global perspective on energy needs shows that more, not less, energy is needed and technological innovation in energy sources is essential in order to meet the needs of more than just the developed countries. Energy-intensive technology is the amplification of our natural resources rather than their depletion. A fundamental bioethical principle must be established if we are to analyze and organize scientific evidence about hazards from currently feasible energy resources, and separate genuine from counterfeit claims to credibility. In particular, public fears about radiation hazards and radioactive waste disposal are influenced too much by rhetorical cleverness and forensic skills of a vociferous minority. Potential hazard management is ethically equitable only if it is proportioned to actual basic harm that can be identified and reduced by expenditures of human effort, time and money

  12. Evaluating energy

    International Nuclear Information System (INIS)

    Gates, D.M.

    1985-01-01

    Intended as a primer on the relationship between the development and use of various energy resources and resulting ecological consequences, the book is designed for a course that can serve students with or without much background in the biological or physical sciences. A review is presented of the major concepts used in atmospheric science, the general picture of energy principles and laws, the status of energy resources both in the United States and worldwide, and an analysis of how questions of energy demand are approached. Three classes of energy sources are addressed: solar, biomass, and coal. The ecological impacts of carbon dioxide, acid deposition, petroleum, electrical power-generation, and nuclear technology are discussed. Also given is a discussion of alternative technologies in energy production

  13. Energy storage

    Kaier, U.

    1981-04-01

    Developments in the area of energy storage are characterized, with respect to theory and laboratory, by an emergence of novel concepts and technologies for storing electric energy and heat. However, there are no new commercial devices on the market. New storage batteries as basis for a wider introduction of electric cars, and latent heat storage devices, as an aid for solar technology applications, with satisfactory performance standards are not yet commercially available. Devices for the intermediate storage of electric energy for solar electric-energy systems, and for satisfying peak-load current demands in the case of public utility companies are considered. In spite of many promising novel developments, there is yet no practical alternative to the lead-acid storage battery. Attention is given to central heat storage for systems transporting heat energy, small-scale heat storage installations, and large-scale technical energy-storage systems.

    This Transportation Energy Project is comprised of four unique tasks which work within the railroad industry to provide solutions in various areas of energy conservation. These tasks addressed: energy reducing yard related decision issues; alternate fuels; energy education, and energy storage for railroad applications. The NIU Engineering and Technology research team examined these areas and provided current solutions which can be used to both provide important reduction in energy usage and system efficiency in the given industry. This project also sought a mode in which rural and long-distance education could be provided. The information developed in each of the project tasks can be applied to all of the rail companies to assist in developing efficiencies.

    2007-04-15

    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.

  18. Energy knowledge

    Energy Technology Data Exchange (ETDEWEB)

    Shove, E. [Lancaster Univ., Centre for the Study of Environmental Change (United Kingdom)

    1997-11-01

    James Thurber`s grandmother `lived the latter years of her life in the horrible suspicion that electricity was dripping invisibly all over the house`. The idea that electricity might leak from empty light sockets is both bizarre and at the same time strangely plausible. Delivered in a variety of forms, gas, electricity, oil, coal, wood etc.; energy permits countless services and is embodied in almost everything we find around us. Both everywhere, and nowhere, it remains a mysterious if not magical feature of everyday life. So the image of leaking light sockets is appealing not just because it is a quaintly ridiculous idea conjured up by a confused old lady but because it precisely articulates lingering uncertainty about the intangible qualities of this most pervasive resource. Taking the invisibility of energy as a point of departure, this paper explores the different kind of knowledge we have of energy use. Although the technologies of domestic energy measurement are familiar enough, we know what a meter looks like and we all get energy bills, it still requires an act of faith to believe in the `reality` of energy consumption. Those who have learned the official languages of energy efficiency have access to richer vocabularies of revealing terminology and can talk more confidently in terms of kilowatts, U values and the rest. But how do these different knowledge relate, and how do different ways of knowing energy influence perceptions of the possibilities and problems of energy conservation? In exploring these issues, the paper re-examines theories of energy and knowledge implicit in energy policy and energy related research. (au) 22 refs.

Comparisons are presented between the wind power performances and European Commission White Paper and Biomass action plan objectives. The sector covers the energy exploitation of all energy flows specifically supplied by the seas and oceans. At present, most efforts in both research and development and in experimental implementation are concentrated on tidal currents and wave power. 90% of today worldwide ocean energy production is represented by a single site: the Rance Tidal Power Plant. Ocean energies must face up two challenges: progress has to be made in finalizing and perfecting technologies and costs must be brought under control. (A.L.B.)

    A compact energy concept opposes the existing development course of energy supply. This concept does without projects for opening-up oil and gas occurrences in the Arctic and in offshore seas, and also without a further extension of nuclear energy. Energy consumption is to be stabilized in the long-run on today's level by a utilization of energy which is to be substantially improved in a technical and economic respect. Oil and gas are to be replaced by 'soft', regenerative, mainly decentralized energy sources, in the course of about 30 years time. Solar energy is to be used for heating and service water, biogas as motor fuel being generated primarily from reference which will come from agriculture and forestry. Wind and hydroelectric power are to be used for generating electricity. In the first part, concepts for the present and future energy policy are discussed, in the second part, a lot of figures are given, supporting the respective arguments. In the third part the relationships between social and energy-economic developments are pointed out. (UA) [de

    Geothermal energy has shown a revival for several years and should strongly develop in a near future. Its potentiality is virtually unexhaustible. Its uses are multiple and various: individual and collective space heating, heat networks, power generation, heat storage, heat exchanges etc.. Re-launched by the demand of renewable energy sources, geothermal energy has become credible thanks to the scientific works published recently which have demonstrated its economical and technical relevance. Its image to the public is changing as well. However, lot of work remains to do to make geothermal energy a real industry in France. Several brakes have to be removed rapidly which concern the noise pollution of geothermal facilities, the risk of bad results of drillings, the electricity costs etc. This dossier gives an overview of today's main research paths in the domain of geothermal energy: 1 - geothermal energy in France: historical development, surface and deep resources, ambitions of the French national energy plan (pluri-annual investment plan for heat generation, incentives, regional 'climate-air-energy' schemes), specific regulations; 2 - geothermal energy at the city scale - sedimentary basins: Ile-de-France 40 years of Dogger reservoir exploitation, potentialities of clastic reservoirs - the Chaunoy sandstones example; 3 - geothermal power generation: conventional reservoirs - the Bouillante model (Guadeloupe, French Indies); the Soultz-sous-Forets pilot plant (Bas-Rhin, France); the supercritical reservoirs - the Krafla geothermal area (Iceland).

Measuring instruments varies from a simple watt-meter to more sophisticated microprocessor control devices. The negative effects...... that fossil fuels induce on our environment has forced us to research renewable energy such as sunlight, wind etc. This new environmental awareness has also helped us to realize the importance of monitoring and controlling our energy use. The main purpose in this research is to introduce a more sophisticated...... but affordable way to monitor energy consumption of individuals or groups of home appliances. By knowing their consumption the utilization can be regulated for more efficient use. A prototype system has been constructed to demonstrate our idea....

    This paper develops economic definitions of energy quality for individual fuels and energy aggregates. There are use- and exchange-value concepts, as well as marginal and total measures, of energy quality. A factor augmentation or quality coefficients approach corresponds to the use-value definition while indicators based on distance functions and relative prices are exchange-value based definitions. These indicators are identical when the elasticity of substitution between fuels is infinity but diverge or cannot be computed for other interfuel elasticities of substitution. When the elasticity of substitution is zero only the quality coefficients approach is defined. I also show that 1) the ratio of an energy volume index to aggregate joules cannot be considered a complete indicator of aggregate energy quality as it does not account for quality changes in the component fuels 2) demand curve integrals do not provide information on relative use-values or fuel qualities when the elasticity of substitution is unity or less.

    Each of the major energy markets for oil, coal, natural gas, biofuels and electricity has its own character. But markets are dependent on each other in an often complicated way. This interconnection has become even more complex since the market for emissions trading began in Europe in 2005. This report describes the current situation of the different energy markets but also the relationships between them, and some possible future scenarios. The oil market is global, but is dominated by a few producing countries. Coal is traded on the international market with good competition and over time probably a stable price. Other markets are more regional or even local. One example is the natural gas market. In the current situation of natural gas is not particularly important for Sweden's energy supply, but very much so in a European perspective. There may be repercussions also in Sweden. The gas price ups and downs are important for the price of emission rights and electricity. Biofuel markets ranging from global markets, such as ethanol, to regional or local markets, depending on processing. Only with the creation of a single trading venue, Nordpool was a common pricing of electricity possible in the Nordic region. In the near future we will have a common electricity market covering at least the Nordic region and northwestern Europe. This does not mean that prices will become equalized, for that further expansion of the transmission capacity is needed. It is possible to imagine several scenarios for future energy markets, but the interaction between the different markets will persist. To develop appropriate instruments is of great importance to achieve the political objectives in the energy field the next decade

    This timely volume provides a comprehensive review of current technology for all ocean energies. It opens with an analysis of ocean thermal energy conversion (OTEC), with and without the use of an intermediate fluid. The historical and economic background is reviewed, and the geographical areas in which this energy could be utilized are pinpointed. The production of hydrogen as a side product, and environmental consequences of OTEC plants are considered. The competitiveness of OTEC with conventional sources of energy is analysed. Optimisation, current research and development potential are also examined. Separate chapters provide a detailed examination of other ocean energy sources. The possible harnessing of solar ponds, ocean currents, and power derived from salinity differences is considered. There is a fascinating study of marine winds, and the question of using the ocean tides as a source of energy is examined, focussing on a number of tidal power plant projects, including data gathered from China, Australia, Great Britain, Korea and the USSR. Wave energy extraction has excited recent interest and activity, with a number of experimental pilot plants being built in northern Europe. This topic is discussed at length in view of its greater chance of implementation. Finally, geothermal and biomass energy are considered, and an assessment of their future is given. The authors also distinguished between energy schemes which might be valuable in less-industrialized regions of the world, but uneconomical in the developed countries. A large number of illustrations support the text. This book will be of particular interest to energy economists, engineers, geologists and oceanographers, and to environmentalists and environmental engineers

    Full Text Available Geothermal technologies use renewable energy resources to generate electricity and direct use of heat while producing very low levels of greenhouse-gas (GHG emissions. 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.

    In France and in Europe, the political vision of energy production has not yet been taken to heart as much as its importance merits, despite a certain awareness of the gravity of the phenomena within the population. It would already be very difficult to halve the consumption of fossil fuels in France in 2050, without a swift and profound change in our energy-consumption choices (in particular in transport) and a considerable research effort. To divide it by four seems unrealistic, since France, unlike other countries, has already benefited from the transition from electricity produced from fossil fuels to nuclear electricity which does not emit CO 2 . A major evolution in energy, in Europe and throughout the World, is inevitable in the course of the century. To prevent this from being too violent and painful, a process of fundamental research and technological development should be launched forthwith, in all fields of energy production, storage and use, with a large effort supported by major research programmes. Some recommendations are given for the main research fields that should be: capture and long term storage of CO 2 , energy savings in transport, energy supply to large cities and nuclear power plant enhancement, hydrogen storage, wind energy and its unavailability problem, use of forest resources, photovoltaic electricity in rural and isolated regions, temporary storage of electricity

    2009-01-01

    There are 5 different ways of harnessing ocean energy: tides, swells, currents, osmotic pressure and deep water thermal gradients. The tidal power sector is the most mature. A single French site - The Rance tidal power station (240 MW) which was commissioned in 1966 produces 90% of the world's ocean energy. Smaller scale power stations operate around the world, 10 are operating in the European Union and 5 are being tested. Underwater generators and wave energy converters are expanding. In France a 1 km 2 sea test platform is planned for 2010. (A.C.)

    The yearly environmental conference will hold on September 2013 to evaluate the negotiations led at the national and local levels for december 2012. The government will have then to decide of an energy programming bill which will be submitted to the Parliament at the beginning of the year 2014. 30 main propositions have emerged of the decentralised debates. One of them is the ecological taxation which raise the question of the gas oil and petrol taxation. The current environmental taxes are for almost three quarters of them taxes on energy consumptions and mainly on fossil energies. The Economic, Social and Environmental Council, gives his opinion on the way to find resources to ensure the ecological and energy transition while reducing the public deficit of the State. (O.M.)

    One form of renewable energy production involves the growing of energy coppice on agricultural land. It is important as it can be grown on those areas of agricultural land which are surplus to agricultural production. Hence it can be seen as an alternative farm crop, and as such, a possible solution to the problem of agricultural surpluses as well as providing a source of energy. Studies have indicated that up to one million hectares of land surplus to agricultural production may be suitable for growing energy coppice. However, its development as an agricultural crop will only happen if it can be produced at costs competitive with alternative fuels and there is a reliable and long term market offering good returns.

    2004-01-01

    World energy demand is constantly rising. This is a legitimate trend, insofar as access to energy enables enhanced quality of life and sanitation levels for populations. On the other hand, such increased consumption generates effects that may be catastrophic for the future of the planet (climate change, environmental imbalance), should this growth conform to the patterns followed, up to recent times, by most industrialized countries. Reduction of greenhouse gas emissions, development of new energy sources and energy efficiency are seen as the major challenges to be taken up for the world of tomorrow. In France, the National Energy Debate indeed emphasized, in 2003, the requirement to control both demand for, and offer of, energy, through a strategic orientation law for energy. The French position corresponds to a slightly singular situation - and a privileged one, compared to other countries - owing to massive use of nuclear power for electricity generation. This option allows France to be responsible for a mere 2% of worldwide greenhouse gas emissions. Real advances can nonetheless still be achieved as regards improved energy efficiency, particularly in the transportation and residential-tertiary sectors, following the lead, in this respect, shown by industry. These two sectors indeed account for over half of the country CO 2 emissions (26% and 25% respectively). With respect to transportation, the work carried out by CEA on the hydrogen pathway, energy converters, and electricity storage has been covered by the preceding chapters. As regards housing, a topic addressed by one of the papers in this chapter, investigations at CEA concern integration of the various devices enabling value-added use of renewable energies. At the same time, the organization is carrying through its activity in the extensive area of heat exchangers, allowing industry to benefit from improved understanding in the modeling of flows.

    This article gives a general overview of the past and present development of geothermal energy worldwide and a more detailed one in Switzerland. Worldwide installed electrical power using geothermal energy sources amounts to 8900 MW el . Worldwide utilization of geothermal energy for thermal applications amounts to 28,000 MW th . The main application (56.5%) is ground-coupled heat pumps, others are thermal spas and swimming pools (17.7%), space heating (14.9%), heating of greenhouses (4.8%), fish farming (2.2%), industrial uses (1,8%), cooling and melting of snow (1.2%), drying of agricultural products (0.6 %). Switzerland has become an important user of geothermal energy only in the past 25 years. Earlier, only the exploitation of geothermal springs (deep aquifers) in Swiss thermal baths had a long tradition, since the time of the Romans. Today, the main use of geothermal energy is as a heat source for heat pumps utilizing vertical borehole heat exchangers of 50 to 350 meters length. 35,000 installations of this type with heating powers ranging from a few kW to 1000 kW already exist, representing the highest density of such installations worldwide. Other developments are geostructures and energy piles, the use of groundwater for heating and cooling, geothermal district heating, the utilization of draining water from tunnels and the project 'Deep Heat Mining' allowing the combined production of heat and electric power

    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.

Moreover and for the aim of assisting the developing countries to produce energy and emission models, the German-Swiss emissions model 'Handbuch der Emissionsfaktoren des Strassenverkehrs 1999' is studied, explained and examined. Also, a new approach was developed, within the framework of this study, 'Push-down and Push-up' with the aim of sustainable energy consumption in the transport sector. Finally, the application illustrates the technical, environmental, and economical benefits of the sustainable transport concept. (orig.)

    Research and development in the field of energy technologies was and still is a rational necessity of our time. However, the current point of main effort has shifted from security of supply to environmental compatibility and safety of the technological processes used. Nuclear fusion is not expected to provide an extension of currently available energy resources until the middle of the next century. Its technological translation will be measured by the same conditions and issues of political acceptance that are relevant to nuclear technology today. Approaches in the major research establishments to studies of regenerative energy systems as elements of modern energy management have led to research and development programs on solar and hydrogen technologies as well as energy storage. The percentage these systems might achieve in a secured energy supply of European national economies is controversial yet today. In the future, the Arbeitsgemeinschaft Grossforschungseinrichtungen (AGF) (Cooperative of Major Research Establishments) will predominantly focus on nuclear safety research and on areas of nuclear waste disposal, which will continue to be a national task even after a reorganization of cooperation in Europe. In addition, they will above all assume tasks of nuclear plant safety research within international cooperation programs based on government agreements, in order to maintain access for the Federal Republic of Germany to an advancing development of nuclear technology in a concurrent partnership with other countries.

    Large areas of the desert southwest are currently developed or being evaluated for construction of utility-scale renewable energy projects. These projects include numerous solar and wind energy facilities some of which will be massive. Unfortunately, peer-reviewed scientific publications are not yet available to evaluate the potential effects of solar-based utility-scale renewable energy development (USRED) on any species of wildlife, including amphibians and reptiles (herpetofauna). Scientific publications on the effects of wind-based USRED and operation (USREDO) are focused almost exclusively on flying wildlife including birds and bats. To the best of our knowledge the only publications on the effects of wind-based USREDO on herpetofauna are three publications on desert tortoise ecology at a wind energy facility near Palm Springs, California. Those studies suggested that not all effects of USREDO were detrimental in the short-term. However, additional research is required to determine if wind energy operation is compatible with conservation of this long-lived species over longer periods of time.

    The wind energy or eolic energy is a consequence of solar energy, the one which is absorbed by the atmosphere and is transformed into energy of movement of large bulks of air. In this process the atmosphere acts as the filter to the solar radiation and demotes the ultraviolet beams that result fatal to life in the Earth. The ionosphere is the most external cap and this is ionized by means of absorption process of ultraviolet radiation arising to the Sun. The atmosphere also acts as a trap to the infrared radiation, it that results from the continual process of energetic degradation. In this way, the interaction between Earth - Atmospheres, is behaved as a great greenhouse, maintaining the constant temperatures, including in the dark nights. Processes as the natural convection (that occur by the thermodynamic phenomenon), equatorial calmness, trade winds and against trade winds and global distribution of the air currents are described. The other hand, techniques as the transformation of the wind into energy and its parameters also are shown

    This set of questions is based on an inquiry from the years 1987 to 1989. About 250 people af all age groups - primarily, however, young people between 16 and 25 years of age - were asked to state the questions they considered particularly important on the subject of nuclear energy. The survey was carried out without handicaps according to the brain-storming principle. Although the results cannot claim to be representative, they certainly reflect the areas of interest of many citizens and also their expectations, hopes and fears in connection with nuclear energy. The greater part of the questions were aimed at three topic areas: The security of nuclear power-stations, the effects of radioactivity on people and the problem of waste disposal. The book centres around these sets of questions. The introduction gives a general survey of the significance of nuclear energy as a whole. After this follow questions to do with the function of nuclear power stations, for the problems of security and waste disposal - which are dealt with in the following chapters - are easier to explain and to understand if a few physical and technical basics are understood. In the final section of the book there are questions on the so-called rejection debate and on the possibility of replacing nuclear energy with other energy forms. (orig./HP) [de

    In a first part, the author proposes an overview of technological developments in the field of power production. He outlines that technological advances may increase assessments of oil and gas reserves but that the associated costs might be too high to keep on exploiting these resources. The problem is almost the same for coal for which the associated costs concern the reduction of pollution and the sequestration and storage of carbon emissions. Nuclear energy avoids this issue of emissions and researches aim at the development of fusion reactors (ITER project) which still are an economic challenge because of their much higher cost in comparison with fission reactors. The author comments the development of renewable energies which however will not be able to replace thermal and nuclear production to face the constant increase of energy consumption. In the second part, the author evokes the various advances in energy production for transports: fuel cells, energy storage, hydrogen storage, and emergence of a hydrogen economy. He finally evokes applications to military propulsions (ground vehicles, marine propulsion, and aircraft propulsion)

    Full Text Available Geothermal technologies use renewable energy resources to generate electricity and direct use of heat while producing very low levels of greenhouse-gas (GHG emissions. Geothermal energy is stored in rocks and in fluids circulating in the underground. Electricity generation 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. Geothermal technology, which has focused so far 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.

    Three major concerns face mankind's future: the impending energy crisis as caused by the depletion of the world's fossil fuel reserves, world atmospheric pollution as caused by the burning of these fuels, and mankind's destruction if the vast energy contained in nuclear weapons stockpiles is released in a global conflict. This paper describes an ambitious, combined solution to these problems by the use of deep underground detonations of thermonuclear devices/bombs to provide a virtually pollution free, world energy source into the far distant future, while achieving a significant increase in mutual trust between the superpowers and all nations. The key is believed to be thermonuclear geothermal stimulation to produce the electrical power needed for a hydrogen economy

    The designated successor to fossil fuels is nuclear fission/fusion and that turns out to be problematic. Alternative Energy Systems have great potential but political forces seem to be hampering their development and introduction. The technologies are flexible in their use and scale of operation. The learning curve will not be short but neither will it be as long and as costly as nuclear power. It is time that this is recognised and some serious rethinking takes place in what presently passes for energy policies both in the industrialised countries and in the Third World. Alternative energy systems are defined and some of them which are relevant to the United Kingdom are discussed. (author)

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.

    Geothermal energy is the natural heat of the earth. It represents an inexhaustible source of energy. In many countries, which are mostly located within the geothermal belts of the world, geothermal energy is being used since many decades for electricity generation and direct heating applications comprising municipal, industrial and agricultural heating. Outside the geothermal anomalous volcanic regions, hot ground water from deep rock formations at temperatures above 70 o C is used for process heat and space heating. Low prices for gas and oil hinder the development of geothermal plants in areas outside positive geothermal anomalies; the cost of drilling to reach depths, where temperatures are above 50 o C to 70 o C, is high. The necessary total investment per MW th installed capacity is in the order of 5 Mio- DM/MW th (3 Mio $/MW th ). Experience shows, that an economic break even with oil is reached at an oil price of 30$ per barrel or if an adequate bonus for the clean, environmentally compatible production of geothermal heat is granted. Worldwide the installed electric capacity of geothermal power plants is approximately 6 000 MW e . About 15 000 MW th of thermal capacity is being extracted for process heat and space heat. The importance of the terrestrial heat as an energy resource would be substantially increased, if the heat, stored in the hot crystalline basement could be extracted at economical production costs. Geothermal energy is a competitive energy source in areas with high geothermal gradients (relative low cost for drilling) and would be competitive in areas with normal geothermal gradients, if a fair compensation for environmental implications from fossil and nuclear power production would be granted.

    The energy problem is set out as it appears to an economist. The paper then explains the nature of the strategic arguments, differentiating particularly between options that might be available to the world as a whole and options that are available to the UK as such. It is concluded that in UK there are no options: that all possible sources of energy should be developed, and all opportunities taken for conservation, subject to broad economic considerations. Government policies and sociological aspects are discussed. (U.K.)

    Bioenergy systems can provide an energy supply that is environmentally sound and sustainable, although, like all energy systems, they have an environmental impact. The impact often depends more on the way the whole system is managed than on the fuel or on the conversion technology. The authors first describe traditional biomass systems: combustion and deforestation; health impact; charcoal conversion; and agricultural residues. A discussion of modern biomass systems follows: biogas; producer gas; alcohol fuels; modern wood fuel resources; and modern biomass combustion. The issue of bioenergy and the environment (land use; air pollution; water; socioeconomic impacts) and a discussion of sustainable bioenergy use complete the paper. 53 refs., 9 figs., 14 tabs

    Toward the future, the petroleum could stop to be the main energy source in the world and the oil companies will only survive if they are adjusted to the new winds that blow in the general energy sector. It will no longer be enough to be the owner of the resource (petroleum or gas) so that a company subsists and be profitable in the long term. The future, it will depend in great measure of the vision with which the oil companies face the globalization concept that begins to experience the world in the energy sector. Concepts like globalization, competition, integration and diversification is something that the companies of the hydrocarbons sector will have very present. Globalization means that it should be been attentive to what happens in the world, beyond of the limits of its territory, or to be caught by competitive surprises that can originate in very distant places. The search of cleaner and friendlier energy sources with the means it is not the only threat that it should fear the petroleum. Their substitution for electricity in the big projects of massive transport, the technology of the communications, the optic fiber and the same relationships with the aboriginal communities are aspects that also compete with the future of the petroleum

    Do we need nuclear energy. Is it safe. What are the risks. Will it lead to proliferation. The questions are endless, the answers often confused. In the vigorous debates that surround the siting and operation of nuclear power plants, it is all too easy to lose sight of the central issues amid the mass of arguments and counter-arguments put forward. And there remains the doubt, who do we believe. This book presents the facts, simply, straightforwardly, and comprehensibly. It describes the different types of nuclear reactor, how they work, how energy is produced and transformed into usable power, how nuclear waste is handled, what safeguards are built in to prevent accident, contamination and misuse. More important, it does this in the context of the real world, examining the benefits as well as the dangers of a nuclear power programme, quantifying the risks, and providing an authoritative account of the nuclear industry worldwide. Technically complex and politically controversial, the contribution of nuclear energy to our future energy requirements is a crucial topic of our time. (author)

It comprises 19 articles dealing with: the big bang of July 1, 2004 in the electricity and gas sector (on July 1, 2004, all professional consumers will have the possibility to chose their electricity and gas supplier. If Electricite de France (EdF) and Gaz de France (GdF) monopolies will split up, several questions remain unanswered for clients); the impossible penetration of the French market (3 weeks before the enhanced opening of power markets, EdF's competitors remain surprisingly limited and are mainly French actors. The big European competitors follow a wait-and-see policy); the independent power producer Compagnie Generale du Rhone wants to diversify its clients and is looking towards local authorities; Direct Energie: the 'low-cost' company for the mutualization of electricity purchases of small professionals; Endesa, the French daughter company of the Spanish electric utility, is looking for a balance between production and sales; HEW, daughter company of Vattenfall Europe and present in France since April 2000, wants to increase its margins more than its capacity; energy profilers are making consumption profiles for EdF's competitors; Poweo, energy retailing company built in 2002, is fetching very small companies; Atel, French daughter company of the Swiss power producer, does not foresee important changes in July 1; interview of F. Roussely, head of EdF about the liberalization of the electricity sector; the main energy groups favorable to deregulation; case study: Accor, the hotel trade group, has chosen Compagnie Generale du Rhone as power supplier; electricity: why prices are increasing; various foreign experiences; UK: the consolidation time (fully liberalized and privatized between several companies, the British energy market is under total re-building); USA: the deregulation process has failed and stays stuck to 24

    The ovulatory activity in the livestock depends on the readiness of nutritious energy with relationship to its use for the nursing. During the early nursing the cup of increment in the production of milk exceeds to the consumption of food, the difference in the energy consumption of the diet with relationship to the energy used for production is a negative energy balance. During the first weeks of nursing this reaches their maximum and it diminishes slowly with the increment in the consumption of dry matter. This first metabolic sign is in an increment in the pulses of hormone luteinizant that acts as and stimulate for the ovary and that with a great readiness of insulin, it takes to the ovarian follicles to respond to the stimulus. The sub-alimentation seems to affect the hypothalamic function and ovarian. The return to the positive energy balance in cows highly producers can be accelerated by the consumption of protected fat. The functions of the lipids are to provide energy for normal maintenance and production, to serve as source of essential fatty acids and eat payee of liposoluble vitamins. The importance of the addition of vegetable fat is that this is not degraded in the rumen but rather it is digested in its entirety in abomasa and absorbed in intestine. The addition of a source of Ca to diets with fats promotes the formation of insoluble soaps achieving that the fat doesn't inhibit the fiber fermentation; the chloride of Ca to be of high solubility in water it is completely ionized in rumen and it is more efficient in the formation of insoluble soaps of Ca. The addition of fat in the diet bears increase in the production of N microbial, inhibition of methane formation, increase and change in population of bacteria and mushrooms. The efficiency of the fat is superior when sources of fatty acids of long chain are used, the employment of these, in its protected form, in a diet, stimulates the number of follicles and it increases its size.

    The Business Council of Australia's study on Prospects for Improved Energy Efficiency and the Application of Renewable Energy Resources is summarised. The study estimates that replacement of all off-peak electric units in Australia with solar gas boosted systems would reduce electricity consumption for residential water heating by approximately 25% and almost halve carbon dioxide emissions resulting from residential water heating. Furthermore, substitution of all water heating units in Australia with solar gas systems would reduce total emissions by about 80%. The study concludes that while substitution on such a scale could not readily be achieved even within several decades, the estimates do indicate the significant benefits that might be realised by a long term program. 2 refs., 3 tabs

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

    The article discusses the identification of efficiencies that can minimise transaction costs in energy trading and marketing. The article describes what is meant by 'trade management'. It is argued that a trade management system should be able to dovetail with existing or future ERP, advanced risk management, and financial management systems, to provide total enterprise integration. With the right trade management systems, traders have all the necessary information to help them manage exposure to financial risks in a world where energy trading companies are forced to accept very small margins. A trade management system can cover many aspects of a business including the winning of contracts for transportation deals, including rail, car, truck, barge and pipeline. There appears to be unprecedented opportunities for companies specialising in development and provision of trade management systems.

    The regulations in the coalition agreement on the energy transition and the climate protection is sad: the 2020 climate protection goal is abandoned. At the same time, this makes the German contribution to the Parisian climate change agreement eroded. The goals are only general described, the paths to it must be a commission ''Growth, Structural change and Employment'' as a basis for a law. The statements on the energy revolution disappoint even more. On Proportion of about 65 percent renewable energy (RES) by 2030 is ''desired''. It would be desirable to cover the ''additional Electricity requirements for achieving the climate protection targets in transport, in buildings and in industry''; one senses: they have in fact already dealing with the sector coupling. But that for a sector coupling that allows to achieve the climate protection goals, a doubling of electricity production is necessary, one can do not read anywhere. Although the policy is committed to Power to X; also the deputy Bareiss of the CDU. But that, for example, at Power to gas only reaches about an efficiency of about 30 percent is hardly anyone speaks. An important reason for the non-binding nature of the statements not only the political dissent, but the high complexity of the Material. For example, the connection between the introduction of a CO{sub 2} tax and the electricity or energy taxation not on the hand. Therefore, the attempt should be made, the demands to set up a theses and briefly explain the connections. This post is intended as an invitation to discuss.

During this time the character of the questions has changed considerably. In the beginning people spoke of fear and anxiety over the plans for the application of this new technical development but later this fear and anxiety turned to protest and opposition. This brochure has been produced to enlighten people and try and answer their alarm, by exploring the many facets of the problems. Some of these problems are already being deeply discussed by the public, others play no role in the forming of public opinion. The points of view of the churches over nuclear energy are not expressed, the brochure endeavours to express that nuclear energy problems are a concern for the churches.

    The measurement of primary interaction cross sections and the incorporation of these data into Monte Carlo calculations provide detailed information about the initial spatial distribution of absorbed dose. Our theoretical energy transport studies have focused on the use of this information to predict the evolution of chemical species formed as a result of the energy deposition. This effort has led to a stochastic approach to diffusion kinetics that can account for the influence of track structure on the yield of free radicals in the radiolysis of water. Fluorescence studies with pulsed alpha particle and proton beams provided the first experimental test of our stochastic model of tract structure effects. Our experimental studies use time-resolved emission spectroscopy to investigate the mechanism of energy transport in nonpolar liquids. Studies of the concentration dependence of time-resolved emission from solutions of benzene in cyclohexane also show the importance of using low benzene concentrations to minimize the influence of benzene dimers on the emission kinetics

    1992-09-01

    Gasoline consumption by passenger cars and light trucks is a major source of air pollution. It also adds to the economy's dependence on petroleum and vulnerability to oil price shocks. Despite these environmental and other costs, called external cost, the price of gasoline, adjusted for inflation, has generally been declining since 1985, encouraging increased consumption. This paper reports that with these concerns in mind, the Chairman, Subcommittee on Environment, House Committee on Science, Space, and Technology, requested that GAO assess policy options for addressing the external costs of gasoline consumption. To do this, GAO identified six major policy options and evaluated whether they addressed several relevant objectives, including economic growth, environmental quality, equity, petroleum conservation, visibility of costs, energy security, traffic congestion, competitiveness, and administrative feasibility

    This is a general report presenting the section VII entitled Nuclear Power of the National Conference on Energy (CNE '94) held in Neptun, Romania, on 13-16 June 1994. The problems addressed were those relating to electric power produced by nuclear power plant, to heat secondary generation, to quality assurance, to safety, etc. A special attention was paid to the commissioning of the first Romanian nuclear power unit, the Cernavoda-1 reactor of CANDU type. The communications were grouped in four subsections. These were: 1. Quality assurance, nuclear safety, and environmental protection; 2. Nuclear power plant, commissioning, and operation; 3. Nuclear power plant inspection, maintenance, and repairs, heavy water technology; 4. Public opinion education. There were 22 reports, altogether

    1990-01-01

    In this book, the authors have produced an analysis of state energy taxation. Their factual findings are of particular relevance to California and other states in their consideration of severance taxes on oil production. It turns out, for example, that while California's tax burden on oil producers is slightly below average among the states, the combined revenues from taxes and royalties (expressed as a percent of the value of production) indicate that California is not easy on oil producers. In fact, California's oil tax system appears to be particularly well suited to its oil industry. Much of the production in the state is relatively high-cost and economically marginal. The state must tread carefully in taxing this production, lest it force it to be curtailed

    International Nuclear Information System (INIS)

    Heitzer, H.

    1977-01-01

    The author emphasizes the necessity and importance of nuclear energy for the energy supply and stresses the point that it is extremely important to return to objective arguments instead of having emotional disputes. In this connection, it would be necessary for the ministries in question to have clear-cut political responsibility from which, under no circumstances, they may escape, and which they cannot pass on to the courts either. Within the framework of listing present problems, the author is concerned with the possibility of improved site planning, the introduction of a plan approval procedure and questions concerning immediately enforceable nuclear licences. He also deals with a proposal, repeatedly made, to improve nuclear licensing procedures on the one hand by introducing a project-free site-appointment procedure, and on the other hand by introducing a simplified licensing procedure for facilities of the same kind. Splitting the procedure into site and facility would make sense solely for the reason that in many cases the objections are, above all, directed against the site. (HP) [de

    To ensure the economic and social development of the countries of Latin America and the Caribbean, one of the problems that have to be addressed is bridging the technology gap that separates the region's countries from those of the so-called First World. In order to achieve this, the indispensable first step is to learn about, evaluate, orient, and promote scientific and technical training of the region's human resources. In this context, OLADE, with the cooperation of the Andean Development Corporation (CAF), undertook an inventory of the region's energy sector training supply and demand in order to identify both the needs of the institutions involved in the sector's development and the training centers that can meet these needs. In order to mitigate and eliminate the impact of Y2K problem, governments, companies and other sector entities are carrying out specific actions, which are described along with the preventive activities that are being implemented by OLADES's Permanent Secretariat.

    The main purpose of the International Thermonuclear Experimental Reactor (ITER) is to develop an experimental fusion reactor through the united efforts of many technologically advanced countries. The ITER terms of reference, issued jointly by the European Community, Japan, the USSR, and the United States, call for an integrated international design activity and constitute the basis of current activities. Joint work on ITER is carried out under the auspices of the International Atomic Energy Agency (IAEA), according to the terms of quadripartite agreement reached between the European Community, Japan, the USSR, and the United States. The site for joint technical work sessions is at the MaxPlanck Institute of Plasma Physics. Garching, Federal Republic of Germany. The ITER activities have two phases: a definition phase performed in 1988 and the present design phase (1989--1990). During the definition phase, a set of ITER technical characteristics and supporting research and development (R ampersand D) activities were developed and reported. The present conceptual design phase of ITER lasts until the end of 1990. The objectives of this phase are to develop the design of ITER, perform a safety and environmental analysis, develop site requirements, define future R ampersand D needs, and estimate cost, manpower, and schedule for construction and operation. A final report will be submitted at the end of 1990. This paper summarizes progress in the ITER program during the 1989 design phase

    Live steam, transformed steam, and steam produced by expansion flashing are outlined with respect to their use in the production of electricity. The capacity, pressure, and temperature of a steam must be determined empirically by exploratory drilling. These factors are dependent on time and on the extent of nearby drilling-activity. Particulars of geothermal-steam power-plants such as steam dryness, hot-water flashing, condensation, gas extraction, and corrosion are discussed in detail. All available data (as per 1962) concerning the costs of operation and construction of geothermal power plants are tabulated. For space-heating purposes, two basic systems are utilized. When little corrosion or precipitation is expected, an open system is used, otherwise, closed systems are necessary. The space-heating system of Reykjavik, Iceland is cited as an example. A brief description of industrial applications of geothermal energy, such as the extraction of NaCl, D/sub 2/O, or boric acid, is provided. Thirty-two references are given.

    Hydrogen is seen by many as a key energetic vector for the 21{sup st} century. Its utilization in fuel cells enables a clean and efficient production of electricity. The possibility to obtain hydrogen from various sources, along with several types of potential applications of fuel cells, have called the attention and investment of developed countries. European Union, United States, Canada and Japan have important programs that establish tied goals for the utilization of fuel cells in transport and distributed energy generation. Aware of the importance of this technology for the energetic future of Brazil, IPEN started 13 years ago the development of fuel cells for stationary and distributed energy applications. Preliminary studies were carried out at the Materials Research Center due to IPEN expertise on nuclear materials development. Based on both, the good initial results and the proposition of the Brazilian Fuel Cell Program (ProH{sub 2} ) by the Ministry of 2 Science, Technology and Innovation (MCTI), IPEN decided to organize an institutional program on the subject, conducted at the Fuel Cell and Hydrogen Center - CCCH. The objectives of the IPEN/CCCH program are based on the MCTI national program, contributing significantly to the national development in this area. The R and D Program was structured in a cross-cutting way involving human and infrastructure resources from many IPEN technical departments. The Center comprises three main areas of interests: PEMFC (Proton Exchange Membrane Fuel Cell); SOFC (Solid Oxide Fuel Cell); and H{sup 2}-Production, mainly from ethanol reforming. More than 50 professionals were engaged at this development, although some in part time, including PhDs, MSc and graduate students and undergraduate students.

    Protocols of quantum energy teleportation (QET), while retaining causality and local energy conservation, enable the transportation of energy from a subsystem of a many-body quantum system to a distant subsystem by local operations and classical communication through ground-state entanglement. We prove two energy-entanglement inequalities for a minimal QET model. These relations help us to gain a profound understanding of entanglement itself as a physical resource by relating entanglement to energy as an evident physical resource.

    2012-01-01

    This paper discusses domestic energy use and energy behaviour. It shows some improvement in domestic energy consumption and adoption of good energy practice. The survey conducted indicated that 35% of homes could improve their energy efficiency by improved tank insulation. In the last 5 years condensing boilers have been installed only in 3% of homes, indicating that householders are unaware of their advantages. Although 88% of surveyed homes had purchased a major appliance in the last 2 years, only 16% had any idea of the energy rating of their new appliances. Use of energy saving light bulbs is predominant in kitchens compared to other rooms. 70–80% of householders undertook some kind of day-to-day energy efficiency measures. 20–35% of householders would like to invest in energy-saving measures but found cost to be a key barrier. Approximately 84% of those surveyed were unaware of the energy rating of their household appliances. Price and brand were the most important factors determining the purchase of a new appliance. Significant energy-saving could be achieved by providing appropriate information to the general public regarding temperature control, efficiency of appliances and energy-saving heating systems. - Highlights: ▶ Good practice in household energy use is being adopted but actual use is rising. ▶ Cost is dominant in energy related decisions purchasing of household appliances. ▶ Energy behaviour is improving but level of awareness needs more work.

    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.

    Economic development requires reliable, affordable electricity that is provided in sufficient quantities to satisfy the minimum energy requirements at a local, regional or national level. As simple as this recipe for economic development appears, technological, infrastructural, financial and developmental considerations must be analysed and balanced to produce a national energy strategy. Complicating that task is the historic fact that energy at the desired price and in the desired quantities can be neither taken for granted nor guaranteed. Energy economics and energy security determine the options available to nations working to establish a sustainable energy strategy for the future.

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

    Full Text Available The article examines the main problems and solutions of energy saving and energy supply in Ukraine. Low energy efficiency has become one of the main factors of the crisis in the Ukrainian economy. The most relevant scientific and methodical approaches to assessment of the level of energy consumption and saving are indicated. The comparative analysis of annual energy use has been made. A potential to solve energy supply problems is strongly correlated with the ability to ensure the innovative development of economy for efficient and economical use of existing and imported energy resources. The ways for reducing of energy resource consumption have been suggested. Creation of technological conditions for the use of alternative energy sources is considered to be rational also. The development of renewable sources of energy (alternative and renewable energy sources will provide a significant effect in reducing the use of traditional energy sources, harmful emissions and greenhouse gas. Under these conditions, increasing of energy efficiency of economy and its competitiveness can be real. Improvement of environmental and social conditions of citizens of the country will mark a positive step towards the EU, and also will cancel some problems of the future generation.

    Thellufsen, Jakob Zinck; Lund, Henrik

    2015-01-01

    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. By using energy system analysis to do hourly simulation...

    The 1996 edition of the World Energy Outlook to 2010 was reviewed. An overview of the energy projections was provided based on assumptions about economic growth and energy prices, geological potential, technological developments, the availability of traditional fuels outside the OECD and the future preferences of energy users. Demand vs. price movements were modelled, based on 'capacity constraints' and 'energy saving ' scenarios. Three major conclusions derived from the projections were: (1) world primary energy demand will grow steadily as it has over the past two decades, (2) fossil fuels will account for 90 per cent of total primary energy demand in 2010, and (3) a structural shift in the shares of different regions in world energy demand is likely to occur, i.e., the OECD share will fall in favor of the share of the ROW (rest of the world). 4 tabs., 9 figs

  14. Energy modeling: nuclear energy as China's main energy after 2040

    International Nuclear Information System (INIS)

    Guo Xingqu

    1987-01-01

    According to the energy modeling and the strategic forecast of China's economic development and population, the energy demand in China in the coming century has been calculated yearly by computer simulation. It is shown by the calculation results that the primary energy consumption in 2050 will be 3.37-4.25 times as that of 2000. The fossil energy will still be the main energy during the early stage of 21st century, but it will be cut down rapidly since 2020s as its annual consumption is increased to 1.656-2.044 x 10 9 tce/a. Because the fossil fuel ressources in China are limited, more and more fossil fuel will be mainly turned to chemical products, and the environmental pollution will be serious if we still use the fossil as a main fuel widely. The amount of renewable energy will be increasing, but its share in the primary energy consumption will be cut down from 36% to about 20% during the first half of next century and then will maintain this portion. In this case, the nuclear energy will be developed rapidly during the early stage of next century and will become the main energy since 2040. The methodology of energy forecast has also been reviewed

    International Nuclear Information System (INIS)

    2004-11-01

    Reports have kept domestic and international audience continuously informed about the latest relations and developments in the Croatian energy system. Annual report presents all characteristic indicators of the Croatian energy system in 2003, outlines their development over a longer past period, and suggests a future course of development of basic energy system indicators. Total primary energy supply in the Republic of Croatia in 2003 was 5.2 percent higher compared to the previous year. The gross domestic product increased by 4.3 percent over the same period. This means that energy intensity, primary energy supply per unit of gross domestic product, increased by 0.9 percent. Compared to the european Union average Croatian energy intensity was approximately 32 percent higher. Total primary energy production, on the other hand, decreased by 1.1 percent compared to 2002. This means that primary energy self-supply, which fell to 46.4 percent, reached its lowest level to-date in the observed period. The remaining energy needs were met by imports, which increased by 1.7 percent. In the structure of total primary energy supply, decrease has been observed only in energy conversion losses, while all other categories increased. Final energy demand increased by 6.7 percent in 2003, with the levels recorded in different sectors ranging from 2.5 percent in industry to 7.5 and 8 percent in transport and other sectors, respectively. In terms of final energy demand, an increase has been recorded in all energy forms except natural gas, whose consumption showed stagnation. This is due to lower consumption in the energy transformation sector and a significant 9.2 percent increase in its final energy demand. A continuous increase in electricity consumption - which reached 4.8 percent in the observed period - is worth nothing. Energy forms which recorded highest consumption increase levels in 2003 are coal (16 percent) and diesel fuel (15 percent). In contrast to the fast increase in

    A new dark energy model, named ''agegraphic dark energy'', has been proposed recently, based on the so-called Karolyhazy uncertainty relation, which arises from quantum mechanics together with general relativity. In this note, we extend the original agegraphic dark energy model by including the interaction between agegraphic dark energy and pressureless (dark) matter. In the interacting agegraphic dark energy model, there are many interesting features different from the original agegraphic dark energy model and holographic dark energy model. The similarity and difference between agegraphic dark energy and holographic dark energy are also discussed. (orig.)

    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. Electricity is

    A concept to produce hydrogen of an energy carrier using nuclear energy was proposed since 1970s, and a number of process based on thermochemical method has been investigated after petroleum shock. As this method is used high temperature based on nuclear reactors, these researches are mainly carried out as a part of application of high temperature reactors, which has been carried out at an aim of the high temperature reactor application in the Japan Atomic Energy Research Institute. On October, 2000, the 'First International Conference for Information Exchange on Hydrogen Production based on Nuclear Energy' was held by auspice of OECD/NEA, where hydrogen energy at energy view in the 21st Century, technology on hydrogen production using nuclear energy, and so on, were published. This commentary was summarized surveys and researches on hydrogen production using nuclear energy carried out by the Nuclear Hydrogen Research Group established on January, 2001 for one year. They contains, views on energy and hydrogen/nuclear energy, hydrogen production using nuclear energy and already finished researches, methods of hydrogen production using nuclear energy and their present conditions, concepts on production plants of nuclear hydrogen, resources on nuclear hydrogen production and effect on global environment, requests from market and acceptability of society, and its future process.

    Every organism takes needed materials or energy from outside and excretes unessential things to outside. This is called a metabolism or energy metabolism. Calculating the amount of energy consumed by human in the world by converting to the amount of metabolism of an animal to survive, the weight of a human being is corresponding to an animal with a weigh of 40 ton. Human beings can find a solution to dissolve energy obesity or can maintain a massive status by finding a new energy source in the universe.

  2. The energy yield of nuclear energy

    1983-01-01

    In this paper, a comparison is made between the energy produced in a nuclear cycle in a light-water reactor without recycling of plutonium or uranium on the one hand and the energy stored into the system to realize this energy production on the other. Only empirical data are used, which means that some energy costs are omitted because no empirical data were available (e.g. energy needed to waste processing and waste disposal). The following steps are taken into account: production and processing of ores, conversion and enrichment of fuels, construction and shutdown of the reactor itself. (Auth.)

  6. Renewable energy worldwide outlooks: solar energy

    International Nuclear Information System (INIS)

    Darnell, J.R.

    1994-01-01

    Solar energy yield is weak because it is very diffuse. The solar energy depends on the weather. The collectors need the beam radiation. Wavelength is important for some applications that include not only the visible spectrum but also infrared and ultraviolet radiation. The areas of the greatest future population growth are high on solar energy resources. We have different types of conversion systems where energy can be converted from solar to electric or thermal energy. Photovoltaic cells are made of silicone or gallium arsenide, this latter for the space use. For the solar energy applications there is a storage problem: electric batteries or superconducting magnets. Today, the highest use of solar energy is in the low temperature thermal category with over 90% of the world contribution from this energy. The penetration of solar energy will be higher in rural areas than in urban regions. But there are technical, institutional, economic constraints. In spite of that the use of solar energy would be increasing and will go on to increase thereafter. The decreasing costs over time are a real phenomenon and there is a broad public support for increased use of that energy. 15 figs

    Addressing energy poverty rather than energy equity conveniently evades the problem of the gap in energy consumption per capita in the developed and developing world. For energy security policies to adequately address energy poverty it requires a widening of scope from national to global. This is a comment to the forthcoming presentation of IEA's proposition for a new architecture for financing universal modern energy access to be presented at the conference 'Energy for all-Financing access for the poor' held in Oslo in October 2011. - Highlights: > Addressing energy poverty may elude the disparity in energy consumption between rich and poor. > A minimum threshold of energy for the poor does not itself address inequity in energy consumption. > Energy equity may be secured by widening scope from national to global, from the poorest to us all.
