The basis of the present contribution of the Federal Ministry of Environment, Nature Conservation and Nuclear Safety (Berlin, Federal Republic of Germany) is the data base of the working group renewable energy statistics. The sequential production of data to the development of the renewable energies in Germany is a more burdensome, constantly repeating process. On the basis of the available data and expert estimations a snapshot of the development of the renewable energies is prepared in each case. The alterations of the data documented here in particular traces back to additional data availability. These data are published in the internet on the topic side 'Renewable Energies' under www.erneuerbare-energien.de in the category 'data service/time series: Development starting from 1990'. These time series are available in Excel format as a download. This topic side also contains diagrams and tables with actual data and further information around the renewable energy.

Biogas in a future energy supply structure with a high proportion of fluctuating renewable energies; Biogas in einer zukuenftigen Energieversorgungsstruktur mit hohen Anteilen fluktuierender Erneuerbarer Energien

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

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).

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.

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.

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.

We investigate the corresponding relation between f(R) gravity and holographic dark energy. We introduce a type of energy density from f(R) that has the same role as holographic dark energy. We obtain the differential equation that specifies the evolution of the introduced energy density parameter based on a varying gravitational constant. We discover the relation for the equation of state parameter for low redshifts that contains varying G correction.

f(R in Holographic and Agegraphic Dark Energy Models and the Generalized Uncertainty Principle

Directory of Open Access Journals (Sweden)

Barun Majumder

2013-01-01

Full Text Available We studied a unified approach with the holographic, new agegraphic, and f(R dark energy model to construct the form of f(R which in general is responsible for the curvature driven explanation of the very early inflation along with presently observed late time acceleration. We considered the generalized uncertainty principle in our approach which incorporated the corrections in the entropy-area relation and thereby modified the energy densities for the cosmological dark energy models considered. We found that holographic and new agegraphic f(R gravity models can behave like phantom or quintessence models in the spatially flat FRW universe. We also found a distinct term in the form of f(R which goes as R 3 / 2 due to the consideration of the GUP modified energy densities. Although the presence of this term in the action can be important in explaining the early inflationary scenario, Capozziello et al. recently showed that f(R ~ R 3 / 2 leads to an accelerated expansion, that is, a negative value for the deceleration parameter q which fits well with SNeIa and WMAP data.

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.

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.

FR4-based electromagnetic energy harvester for wireless sensor nodes

Science.gov (United States)

Hatipoglu, G.; Ürey, H.

2010-01-01

Electromagnetic (EM) energy harvesting seems to be one of the most promising ways to power wireless sensors in a wireless sensor network. In this paper, FR4, the most commonly used PCB material, is utilized as a mechanical vibrating structure for EM energy harvesting for body-worn sensors and intelligent tire sensors, which involve impact loadings. FR4 can be a better material for such applications compared to silicon MEMS devices due to lower stiffness and broadband response. In order to demonstrate FR4 performance and broadband response, three moving magnet type EM generator designs are developed and investigated throughout the paper. A velocity-damped harvester simulation model is first developed, including a detailed magnetic model and the magnetic damping effects. The numerical results agree well with the experimental results. Human running acceleration at the hip area that is obtained experimentally is simulated in order to demonstrate system performance, which results in a scavenged power of about 40 µW with 15 m s-2 acceleration input. The designed FR4 energy scavengers with mechanical stoppers implemented are particularly well suited for nearly periodic and non-sinusoidal high- g excitations with rich harmonic content. For the intelligent tire applications, a special compact FR4 scavenger is designed that is able to withstand large shocks and vibrations due to mechanical shock stoppers built into the structure. Using our design, 0.4 mW power across a load resistance at off-resonance operation is obtained in shaker experiments. In the actual operation, the tangential accelerations as a result of the tire-road contact are estimated to supply power around 1 mW with our design, which is sufficient for powering wireless tire sensors. The normalized power density (NPD) of the designed actuators compares favorably with most actuators reported in the literature.

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?.

Energy autonomy. A new policy for renewable energies; Energieautonomie. Eine neue Politik fuer erneuerbare Energien

Energy Technology Data Exchange (ETDEWEB)

Scheer, H.

2005-07-01

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.

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 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.

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.

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.

Reconstructing an f(R) model from holographic dark energy: using the observational evidence

International Nuclear Information System (INIS)

Saaidi, Kh; Aghamohammadi, A

We investigate the correspondence relation between f(R) gravity and an interacting holographic dark energy (HDE). By obtaining the conditions needed for some observational evidence such as positive acceleration expansion of the Universe, crossing the phantom divide line and validity of the thermodynamics second law in an interacting HDE model and corresponding it with the f(R) model of gravity, we find a viable f(R) model that can explain the present Universe. We also obtain the explicit evolutionary forms of the corresponding scalar field, potential and scale factor of the Universe. (paper)

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. Dabei bleibt zumeist die Frage offen, wie viel Strom langfristig benoetigt wird. Ein Vergleich von vier sektoruebergreifenden Zielszenarien zeigt, dass der Stromverbrauch im Jahr 2050 je nach Annahmen und Interpretation der Klimaziele weitaus hoeher liegen koennte als bisher vielfach angenommen.

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.

In this work wormholes in viable f(R) gravity models are analyzed. We are interested in exact solutions for stress-energy tensor components depending on different shape and redshift functions. Several solutions of gravitational equations for different f(R) models are examined. The solutions found imply no need for exotic material, while this need is implied in the standard general theory of relativity. A simple expression for weak energy condition (WEC) violation near the throat is derived and analyzed. High curvature regime is also discussed, as well as the question of the highest possible values of the Ricci scalar for which the WEC is not violated near the throat, and corresponding functions are calculated for several models. The approach here differs from the one that has been common since no additional assumptions to simplify the equations have been made, and the functions in f(R) models are not considered to be arbitrary functions, but rather a feature of the theory that has to be evaluated on the basis of consistency with observations for the Solar System and cosmological evolution. Therefore in this work we show that the existence of wormholes without exotic matter is not only possible in simple arbitrary f(R) models, but also in models that are in accordance with empirical data.

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

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.

High Energy Gamma-rays from FR I Jets

CERN Document Server

Sikora, M

2003-01-01

Thanks to Hubble and Chandra telescopes, some of the large scale jets in extragalactic radio sources are now being observed at optical and X-ray frequencies. For the FR I objects the synchrotron nature of this emission is surely established, although a lot of uncertainties--connected for example with the particle acceleration processes involved--remain. In this paper we study production of high energy gamma-rays in FR I kiloparsec-scale jets by inverse-Compton emission of the synchrotron-emitting electrons. We consider different origin of seed photons contributing to the inverse-Compton scattering, including nuclear jet radiation as well as ambient, stellar and circumstellar emission of the host galaxies. We discuss how future detections or non-detections of the evaluated gamma-ray fluxes can provide constraints on the unknown large scale jet parameters, i.e. the magnetic field intensity and the jet Doppler factor. For the nearby sources Centaurus A and M 87, we find measurable fluxes of TeV photons resulting...

Renewable Energy Sources Act and Trading of Emission Certificates: A national and a supranational tool direct energy turnover to renewable electricity-supply in Germany

International Nuclear Information System (INIS)

Kirsten, Selder

2014-01-01

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%

High-energy neutrinos from FR0 radio galaxies?

Science.gov (United States)

Tavecchio, F.; Righi, C.; Capetti, A.; Grandi, P.; Ghisellini, G.

2018-04-01

The sources responsible for the emission of high-energy (≳100 TeV) neutrinos detected by IceCube are still unknown. Among the possible candidates, active galactic nuclei with relativistic jets are often examined, since the outflowing plasma seems to offer the ideal environment to accelerate the required parent high-energy cosmic rays. The non-detection of single-point sources or - almost equivalently - the absence, in the IceCube events, of multiplets originating from the same sky position - constrains the cosmic density and the neutrino output of these sources, pointing to a numerous population of faint sources. Here we explore the possibility that FR0 radio galaxies, the population of compact sources recently identified in large radio and optical surveys and representing the bulk of radio-loud AGN population, can represent suitable candidates for neutrino emission. Modelling the spectral energy distribution of an FR0 radio galaxy recently associated with a γ-ray source detected by the Large Area Telescope onboard Fermi, we derive the physical parameters of its jet, in particular the power carried by it. We consider the possible mechanisms of neutrino production, concluding that pγ reactions in the jet between protons and ambient radiation is too inefficient to sustain the required output. We propose an alternative scenario, in which protons, accelerated in the jet, escape from it and diffuse in the host galaxy, producing neutrinos as a result of pp scattering with the interstellar gas, in strict analogy with the processes taking place in star-forming galaxies.

Energy turnaround in South Africa. Opportunities for investment in renewable energy projects; Energiewende in Suedafrika. Investitionsmoeglichkeiten in erneuerbare Energie-Projekte

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.

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

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.

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)

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.

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.

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

2016-01-01

Modified theories of gravity have attracted much attention of the researchers in the recent years. In particular, the f(R) theory has been investigated extensively due to important f(R) gravity models in cosmological contexts. This paper is devoted to exploring an anisotropic universe in metric f(R) gravity. A locally rotationally symmetric Bianchi type I cosmological model is considered for this purpose. Exact solutions of modified field equations are obtained for a well-known f(R) gravity model. The energy conditions are also discussed for the model under consideration. The viability of the model is investigated via graphical analysis using the present-day values of cosmological parameters. The model satisfies null energy, weak energy, and dominant energy conditions for a particular range of the anisotropy parameter while the strong energy condition is violated, which shows that the anisotropic universe in f(R) gravity supports the crucial issue of accelerated expansion of the universe.

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.

f(R) gravity and chameleon theories

International Nuclear Information System (INIS)

Brax, Philippe; Bruck, Carsten van de; Davis, Anne-Christine; Shaw, Douglas J.

2008-01-01

We analyze f(R) modifications of Einstein's gravity as dark energy models in the light of their connection with chameleon theories. Formulated as scalar-tensor theories, the f(R) theories imply the existence of a strong coupling of the scalar field to matter. This would violate all experimental gravitational tests on deviations from Newton's law. Fortunately, the existence of a matter dependent mass and a thin-shell effect allows one to alleviate these constraints. The thin-shell condition also implies strong restrictions on the cosmological dynamics of the f(R) theories. As a consequence, we find that the equation of state of dark energy is constrained to be extremely close to -1 in the recent past. We also examine the potential effects of f(R) theories in the context of the Eoet-wash experiments. We show that the requirement of a thin shell for the test bodies is not enough to guarantee a null result on deviations from Newton's law. As long as dark energy accounts for a sizeable fraction of the total energy density of the Universe, the constraints that we deduce also forbid any measurable deviation of the dark energy equation of state from -1. All in all, we find that both cosmological and laboratory tests imply that f(R) models are almost coincident with a ΛCDM model at the background level.

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)

2017-08-15

The scalar-tensor f(R) theory of gravity is considered in the framework of a simple inhomogeneous space-time model. In this research we use the reconstruction technique to look for possible evolving wormhole solutions within viable f(R) gravity formalism. These f(R) models are then constrained so that they are consistent with existing experimental data. Energy conditions related to the matter threading the wormhole are analyzed graphically and are in general found to obey the null energy conditions (NEC) in regions around the throat, while in the limit f(R) = R, NEC can be violated at large in regions around the throat.

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.)

2013-01-01

With the second workshop on Energy for Sustainable Science wrapping up in the CERN Main Auditorium, Chairman Frédérick Bordry takes this opportunity to discuss how CERN is contributing to the Sustainable Science conversation.   The second workshop on energy for sustainable science ended with a clear conclusion: energy is a key parameter in future projects. When we design scientific experiments and the related infrastructures it is imperative to think ahead about how energy will be managed. At the same time, we can’t forget that our Organization, like other leading laboratories, was created when the climate was significantly different and when the concept of ‘sustainability’ hadn’t yet been coined! This means that existing facilities have to adopt an energy policy that informs new projects but can also gradually implement changes in existing operations. This is what is happening at CERN and in many other research facilities, as pre...

We consider FRW cosmology in f(R)= R + γR{sup 2} + δR{sup 3} modified framework. The Palatini approach reduces its dynamics to the simple generalization of Friedmann equation. Thus we study the dynamics in two-dimensional phase space with some details. After reformulation of the model in the Einstein frame, it reduces to the FRW cosmological model with a homogeneous scalar field and vanishing kinetic energy term. This potential determines the running cosmological constant term as a function of the Ricci scalar. As a result we obtain the emergent dark energy parametrization from the covariant theory. We study also singularities of the model and demonstrate that in the Einstein frame some undesirable singularities disappear. (orig.)

Power supply in future: ecological aspects; Kuenftige Stromversorgung: Oekologische Aspekte

Energy Technology Data Exchange (ETDEWEB)

The most important prerequisites for an ecological supply of energy in the future is the opting out of nuclear energy and the completion of the second and third phase of the socio-ecological tax reform. As a part of our energy will continue to be generated on the basis of fossil fuels in the foreseeable future, it is essential that a radical change takes place in the efficiency of fossil energy engineering. In addition to this, any possible energy-saving potential must be exploited; this includes the new energy-saving law, promoting the modernisation of old buildings and modern energy management (heat insulation, heating engineering, warm water heating etc.). For an ecological power supply the share of renewable energies must be increased to form a major pillar of our power supply. The '100,000-roof' programme of the German federal government and the development programme for near-market renewable energy sources form part of this approach. Energy research should shift its orientation and accelerate the conversion of our power supply: priority should be given to developing energy-saving technologies and renewable energy. Supporting municipalities and public utilities is especially important. This means revising the basic conditions of energy laws so that they assist public utilities to face competition as power utilities. (orig.) [German] Wichtigste Voraussetzung fuer eine kuenftige oekologische Stromversorgung sind der Ausstieg aus der Atomenergie sowie die Vollendung der zweiten und dritten Stufe der oekologisch-sozialen Steuerreform. Da in absehbarer Zeit ein Teil der Energieerzeugung weiterhin auf Basis fossiler Energietraeger erfolgen wird, ist eine Effizienzrevolution bei den fossilen Energietechnologien notwendig. Darueber hinaus muessen die erschliessbaren Energieeinsparpotentiale genutzt werden; dazu gehoeren die neue Energiesparverordnung, die Foerderung der Altbausanierung sowie ein modernes Energiemanagement (Waermedaemmung

The aim of this study is to discuss the long term analysis of post-Kyoto commitments, with the modelling tool ETSAP-TIAM-FR. Through the specification of CO2 mitigation targets scenarios covering the period 2000-2050, this analysis focuses on the effects of these carbon constraints on several indicators such as global and regional CO2 emissions, the cost of the climate policy, carbon marginal costs, the primary energy consumption and the energy mix. This paper compares global efforts of CO2 mitigation with the cost of carbon and finally discusses the development of CCS technologies.

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

Energy Technology Data Exchange (ETDEWEB)

Walter, M. [ECOCAMPING e.V., Konstanz (Germany)

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 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.

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.

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).

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.

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.

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.

Full Text Available Motivated by UV completion of general relativity with a modification of a geometry at high energy scale, it is expected to have an energy dependent geometry. In this paper, we introduce charged black hole solutions with power Maxwell invariant source in the context of gravity’s rainbow. In addition, we investigate two classes of F(R gravity’s rainbow solutions. At first, we study energy dependent F(R gravity without energy-momentum tensor, and then we obtain F(R gravity’s rainbow in the presence of conformally invariant Maxwell source. We study geometrical properties of the mentioned solutions and compare their results. We also give some related comments regarding thermodynamical behavior of the obtained solutions and discuss thermal stability of the solutions.

Integration of renewable energies in the electricity market; Integration erneuerbarer Energien in den Strommarkt

Energy Technology Data Exchange (ETDEWEB)

Schwarz, Eike

2014-08-15

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.

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.

In this paper, we investigate the late-time cosmic acceleration in mimetic f(R, T) gravity with the Lagrange multiplier and potential in a Universe containing, besides radiation and dark energy, a self-interacting (collisional) matter. We obtain through the modified Friedmann equations the main equation that can describe the cosmological evolution. Then, with several models from Q(z) and the well-known particular model f(R, T), we perform an analysis of the late-time evolution. We examine the behavior of the Hubble parameter, the dark energy equation of state and the total effective equation of state and in each case we compare the resulting picture with the non-collisional matter (assumed as dust) and also with the collisional matter in mimetic f(R, T) gravity. The results obtained are in good agreement with the observational data and show that in the presence of the collisional matter the dark energy oscillations in mimetic f(R, T) gravity can be damped.

We study FRW cosmology for a non-linear modified F(R) Horava-Lifshitz gravity which has a viable convenient counterpart. A unified description of early-time inflation and late-time acceleration is possible in this theory, but the cosmological dynamic details are generically different from the ones of the convenient viable F(R) model. Remarkably, for some specific choice of parameters they do coincide. The emergence of finite-time future singularities is investigated in detail. It is shown that these singularities can be cured by adding an extra, higher-derivative term, which turns out to be qualitatively different when compared with the corresponding one of the convenient F(R) theory.

Anaerobic processes have long been competing with composting of native organic waste materials. While they are technically more complex, they have advantages over composting. They are climate-neutral with regard to CO{sub 2} emissions. This supports the intention of the German government, i.e. to reduce climate-relevant gaseous emissions by 40% by 2020 as compared to 1990, and to have a 35% share of renewable energy sources in electric power supply by 2020. The German Renewables Act (EEG) provided a basis for the establishment and further development of fermentation technology since 2004. (orig.) [German] Die anaerobe Behandlung von organischen Abfaellen gewinnt immer mehr an Bedeutung. Die Entsorgungsaufgabe mit der Erzeugung von Energie zu verbinden wird dabei zunehmend akzeptiert. Vergaerungsverfahren lagen dabei lange Zeit im wirtschaftlichen Wettbewerb zur Kompostierung von nativ-organischen Abfaellen. Anaerobe Verfahren sind technisch aufwendiger, haben jedoch gegenueber der Kompostierung deutliche Vorteile. Sie arbeiten bezueglich der CO{sub 2}-Emissionen klimaneutral. Dies unterstuetzt die Vorgabe der Bundesregierung bis 2020 die treibhausrelevanten Gase gegenueber 1990 um 40% zu reduzieren sowie bis 2020 35% der Stromversorgung durch erneuerbare Energien bereitzustellen. Das Erneuerbare-Energien-Gesetz (EEG) hat seit 2004 die Etablierung und Weiterentwicklung der Vergaerungstechnologie dabei wesentlich gepraegt. (orig.)

This study intends to develop an efficient market design for the German electricity market, with particular regard to renewable energy sources. The German electricity market is disintegrated, i.e. market sectors are not coordinated by a central agency but by their own interactions. The first part of the investigation analyzes the interdependences of market sectors, while the second part will analyze funding instruments for renewable energy sources on this basis. (orig.)

Efficient integration of renewable energies in the German electricity market; Effiziente Integration erneuerbarer Energien in den deutschen Elektrizitaetsmarkt

Energy Technology Data Exchange (ETDEWEB)

Nabe, C.A.

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

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

The 21st century society will be facing growing demand of energy, global environmental issues and concerns about fossil fuel exhaustion. In this society, it is essential to seek for a sustainable energy system to solve these energy-related concerns. In order to find ways for solving these problems, 'Feasibility Study on Commercialized FR Cycle System' was launched in 1999 as a joint research project of JNC, electric utilities, JAERI, CRIEPI etc. This project aims to build promising FR cycle technologies for the 21st century. Now, we are in the second phase (JFY 2001-2005) of this project. At the end of the second phase, we will propose promising concepts through applying innovative technologies. We started this Feasibility Study with defining the development target, which ended in five items; safety, economy, environmental burden, resource utilization and nuclear non-proliferation. These items should also serve as basic viewpoints to evaluate achievements of the study. This paper describes how we evaluate FR cycle options to come up with the final promising candidates. This paper also describes a prospective scenario to introduce FR cycle system, which shows how the FR cycle will be replacing existing LWRs by using limited natural uranium resource and spent fuels.

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.

Energy transition and legal transition: renewable energies development in France

International Nuclear Information System (INIS)

Darson, Alice

2015-01-01

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

Subsidisation of renewable energy; Subventionierung von erneuerbarer Energie. Eine industrieoekonomische Analyse des strategischen Weettbewerbs in der Erneuerbaren-Energieindustrie bei unterschiedlichen staatlichen Regulierungen

Energy Technology Data Exchange (ETDEWEB)

Schaller, M.

2006-07-01

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

It is well known that f(R) gravity models formulated in the Einstein conformal frame are equivalent to Einstein gravity together with a minimally coupled scalar field. In this case, the scalar field couples with the matter sector and the coupling term is given by the conformal factor. We apply the holographic principle to such interacting models. In a spatially flat universe, we show that the Einstein frame representation of f(R) models leads to a constant ratio of energy densities of dark matter to dark energy.

The level structures of 211 Fr, 212 Fr and 213 Fr have been observed to high spins, approx. 28(h/2π) (and excitation energies approx. 8 MeV) using a variety of gamma-ray spectroscopic techniques. The structure of these nuclides is discussed in terms of couplings of single particle states through empirical shell model calculations. Good agreement with experiment is obtained. In 212 Fr and 213 Fr core-excited configurations are required to explain the properties of the highest states. A number of long lived states were observed in each nucleus some of which decay by by enhanced E3 transitions. The E3 transition strengths are discussed

Speaking from the platform of the XIIIth annual session of the International Atomic Energy Agency, at New Delhi, AEC managing director Michel Pecqueur made a solemn appeal to the world community for the decisions which are needed on energy. The present energy crisis can lead the world to a recession and be a factor in grave troubles for peace and balance in the world. The crisis cannot be resolved without accrued recourse to the use of nuclear energy. Two essential themes were outlined: the development of nuclear energy in the world, and the increased reduction of proliferation risks. In concluding, he expressed the hop that with a greater effort in information media, the nuclear fact-of-life would be better accepted by the general public in future, for it is there that lies a brake which may hinder nuclear energy development [fr

The simplest non-minimal matter-geometry coupling in the f(R, T) cosmology

f(R, T) gravity is an extended theory of gravity in which the gravitational action contains general terms of both the Ricci scalar R and the trace of the energy-momentum tensor T. In this way, f(R, T) models are capable of describing a non-minimal coupling between geometry (through terms in R) and matter (through terms in T). In this article we construct a cosmological model from the simplest non-minimal matter-geometry coupling within the f(R, T) gravity formalism, by means of an effective energy-momentum tensor, given by the sum of the usual matter energy-momentum tensor with a dark energy contribution, with the latter coming from the matter-geometry coupling terms. We apply the energy conditions to our solutions in order to obtain a range of values for the free parameters of the model which yield a healthy and well-behaved scenario. For some values of the free parameters which are submissive to the energy conditions application, it is possible to predict a transition from a decelerated period of the expansion of the universe to a period of acceleration (dark energy era). We also propose further applications of this particular case of the f(R, T) formalism in order to check its reliability in other fields, rather than cosmology. (orig.)

Sociology of the energy turnaround. Renewable energy sources and transition of rural regions; Soziologie der Energiewende. Erneuerbare Energien und die Transition des laendlichen Raums

Energy Technology Data Exchange (ETDEWEB)

Kunze, Conrad

2012-11-01

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.

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.

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.

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.

Experimental and theoretical investigations of the decays of 206Fr and 208Fr

International Nuclear Information System (INIS)

Ritchie, B.G.

1979-01-01

206 Fr and 208 Fr were mass separated and observed with large-volume semiconductor detectors in calibrated geometries. Alpha, gamma, and electron singles and gamma-gamma and gamma-electron coincidence data were taken. The alpha decay experiments permitted the determination of the alpha branching ratios for 206 208 Fr as well as 205 207 Fr. The method used includes the information obtained from the electron capture decay studies of those nuclei. The alpha branching ratios obtained are generally higher than those reported previously. Energies and half-lives are in general agreement with previous measurements. The alpha measurements also revealed the presence of a heretofore unobserved alpha-emitting isomer in 206 Fr. The isomer has a half-life of 0.7 +- 0.1 seconds, and the energy of the associated alpha decay is 6.930 +- 0.005 MeV. Gamma data taken with the alpha measurements suggest that the isomeric level is 531 keV above the 206 Fr ground state, with the associated alpha decay populating a level at 391 keV in the 202 At nucleus. Measured alpha branching ratios were analyzed with the Rasmussen reduced width formalism. All observed francium decays were deduced to be unhindered. This study produced detailed level schemes for 206 Rn and 208 Rn. The gamma and electron data permitted the determination of internal conversion coefficients, multipolarities, spins, and parities. It appears from systematics that two different bands of states above J/sup π/ = 4+ are populated by in-beam studies. The deduced level scheme of 208 Rn was studied in the interacting boson approximation (IBA) with the computer code PHINT. The level scheme is readily explained with this model up to around 2 MeV. Good agreement between theory and experiment was also obtained for 204 Rn and 206 Rn, but the limited detail in these decay schemes does not provide conclusive evidence for the applicability of the IBA. 28 figures, 10 tables

Future dynamics in f(R) theories

2015-01-01

The f(R) gravity theories provide an alternative way to explain the current cosmic acceleration without invoking a dark energy matter component used in the cosmological modeling in the framework of general relativity. However, the freedom in the choice of the functional forms of f(R) gives rise to the problem of the degeneracy among these gravity theories on theoretical and (or) observational grounds. In this paper we examine the question as to whether the future dynamics can be used to break the degeneracy between f(R) gravity theories by investigating the dynamics of spatially homogeneous and isotropic dust flat models in two f(R) gravity theories, namely the well known f(R) = R+αR n gravity and another byAviles et al., whose motivation comes from the cosmographic approach to f(R) gravity. We perform a detailed numerical study of the dynamics of these theories taking into account the recent constraints on the cosmological parameters made by the Planck Collaboration. We demonstrate that besides being useful for discriminating between these two f(R) gravity theories, the future dynamics technique can also be used to determine the finite-time behavior as well as the fate of the Universe in the framework of these f(R) gravity theories. There also emerges from our analysis the result that one still can have a dust flat FLRWsolution with a big rip, if gravity is governed by f(R) = R+αR n . We also show that FLRW dust solutions with f'' < 0 do not necessarily lead to singularities. (orig.)

Keys to evaluating and comparing FR fabric

Enright, M. [Westex Inc., Chicago, IL (United States)

Exposure to electric arc flashes can result in the ignition of clothing, and can kill people at distances of 10 feet. This article discussed recent standards and regulations passed to ensure that employees working on or near energized electrical equipment use protective clothing made of flame resistant (FR) fabrics. The codes will require companies to comply with CSA Standard Z462 and determine which protective garments and FR fabrics are available. Employers will also be required to perform flash hazard analyses in order to determine the potential energy of hazards. Flash hazard analyses are typically performed by calculating the potential incident energy of equipment. Protective clothing is required to meet corresponding hazard risk categories. The ASTM F1506 Standard was developed to provide minimum specifications for protective clothing. The standard requires that the fabric used in protective garments must be resistant to arc flashes of varying energy levels. Many companies are simplifying compliance to the standards by implementing uniform programs that meet the highest requirements of the Standards. Arc flash suits are then made available for tasks involving higher energy level equipment. It was concluded that it is important to identify potential hazards and obtain industry consensus standards before investing in FR protective clothing. 2 figs.

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

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 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.

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.

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

In-depth investigation of (α-γ)-coincidences at the 225 Ac decay is carried out. Twenty-one new weak γ-rays are found; 18 γ-rays earlier ascribed to the 225 Ac decay are not confirmed. The quantitative analysis of the (α-γ)-coincidences makes it possible to find the intensity of population of 221 Fr levels by the α decay and multipolarities of five weak γ-transitions. The conversion electron spectrum is investigated in the range of 5-24 keV with a high (some 20 eV) energy resolution. A new M1 type 10.6-keV γ-transition is found. The proposed 225 Ac decay scheme includes 31 excited 221 Fr states. Parities are established for 16 of them. Possible spin values are proposed for 221 Fr levels. Properties of excited 221 Fr states are satisfactorily described by the quasiparticle-phonon nuclear model without the assumption of static octupole deformation

IIn this paper, we determine regular black hole solutions using a very general f(R) theory, coupled to a nonlinear electromagnetic field given by a Lagrangian L{sub NED}. The functions f(R) and L{sub NED} are in principle left unspecified. Instead, the model is constructed through a choice of the mass function M(r) presented in the metric coefficients. Solutions which have a regular behaviour of the geometric invariants are found. These solutions have two horizons, the event horizon and the Cauchy horizon. All energy conditions are satisfied in the whole space-time, except the strong energy condition (SEC), which is violated near the Cauchy horizon.We present also a new theorem related to the energy conditions in f(R) gravity, re-obtaining the well-known conditions in the context of general relativity when the geometry of the solution is the same.

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

A Search for High-Energy Counterparts to Fast Radio Bursts

2018-01-01

We report on a search for high-energy counterparts to Fast Radio Bursts (FRBs) with the Fermi Gamma-ray Burst Monitor (GBM), Fermi Large Area Telescope (LAT), and the Swift Burst Alert Telescope (BAT). We find no significant associations for any of the 14 FRBs in our sample, but report upper limits to the high-energy fluence for each on timescales of ∼0.1, 1, 10, and 100 s. We report lower limits on the radio to high-energy fluence, fr / fγ, for timescales of ∼0.1 and 100 s. The non-detection of high-energy emission is expected if FRBs are analogous to the giant pulses seen from the Crab pulsar, but the observed radio fluences of FRBs are orders of magnitude larger than even the most extreme giant pulses would be at the implied cosmological distances. It has also been proposed that events similar to magnetar hyperflares produce FRBs; this might be a viable model, but our fr / fγ lower limits are in tension with the fr / fγ upper limit for the 2004 superburst of SGR 1806‑20, for 6 out of the 12 FRBs that we study. This demonstrates the utility of analyses of high-energy data for FRBs in tracking down the nature of these elusive sources.

Full text: Considerable attention has been given to nuclei with A = 220 - 230 recently. In this region there occurs transition from the spherical to the deformed nuclear shape, which gives rise to some specific features in the nuclear structure. In particular, negative parity levels with low excitation energies have been found in even-even nuclei from this region [1, 2]. One of the nuclei allowing experimental investigation of the above properties is 221 Fr. The nuclide 221 Fr is from the region of isotopes which does not include stable nuclei and thus it cannot be studied in several-nucleon transfer reactions. In addition, the neutron excess in this nucleus makes it impossible to study the nucleus in reactions with heavy ions. Experimental information on the 221 Fr level structure can only be gained from investigation of the 225 Ac (T 1/2 = 10 days) alpha decay or the 221 Rn (T 1/2 = 25 min) beta decay. In the latter case the possibilities of the investigation are restricted by difficulties in making of 221 Rn sources. Therefore, most information on the structure and properties of 221 Fr is derived from investigation of the 225 Ac α -decay [3]. In-depth investigation of ( α - γ )- coincidences at the 225 Ac decay is carried out. Twenty-one new weak γ - rays are found; 18 γ-rays earlier ascribed to the 225 Ac decay are not confirmed. The quantitative analysis of the ( α - γ )- coincidences makes it possible to find the intensity of 221 Fr levels by the decay and multipolarities of five weak γ -transitions.

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.

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.

Current study highlights the materialization of anisotropic compact stars in the context of f(R, G) theory of gravity. In particular, to gain insight in the physical behavior of three stars namely, Her X1, SAX J 1808-3658 and 4U 1820-30, energy density, and radial and tangential pressures are calculated. The f(R, G) gravity model is split into a Starobinsky like f(R) model and a power law f(G) model. The main feature of the work is a 3-dimensional graphical analysis in which, anisotropic measurements, energy conditions and stability attributes of these stars are discussed. It is shown that all three stars behave as usual for positive values of the f(G) model parameter n. (orig.)

Time-inconsistency can arise when a government attempts to convince private sector to use a particular alternative energy (gas, green electricity...) rather than petroleum products. By introducing taxes and feed-in prices, a government would encourage firms and households to switch to an alternative energy rather than use petroleum products.

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.)

Cosmological reconstruction of realistic modified F(R) gravities

International Nuclear Information System (INIS)

Nojiri, Shin'ichi; Odintsov, Sergei D.; Saez-Gomez, Diego

2009-01-01

The cosmological reconstruction scheme for modified F(R) gravity is developed in terms of e-folding (or, redshift). It is demonstrated how any FRW cosmology may emerge from specific F(R) theory. The specific examples of well-known cosmological evolution are reconstructed, including ΛCDM cosmology, deceleration with transition to phantom superacceleration era which may develop singularity or be transient. The application of this scheme to viable F(R) gravities unifying inflation with dark energy era is proposed. The additional reconstruction of such models leads to non-leading gravitational correction mainly relevant at the early/late universe and helping to pass the cosmological bounds (if necessary). It is also shown how cosmological reconstruction scheme may be generalized in the presence of scalar field.

2011-01-01

Theories of gravity other than general relativity (GR) can explain the observed cosmic acceleration without a cosmological constant. One such class of theories of gravity is f(R). Metric f(R) theories have been proven to be equivalent to Brans-Dicke (BD) scalar-tensor gravity without a kinetic term (ω = 0). Using this equivalence and a 3+1 decomposition of the theory, it has been shown that metric f(R) gravity admits a well-posed initial value problem. However, it has not been proven that the 3+1 evolution equations of metric f(R) gravity preserve the (Hamiltonian and momentum) constraints. In this paper, we show that this is indeed the case. In addition, we show that the mathematical form of the constraint propagation equations in BD-equilavent f(R) gravity and in f(R) gravity in both the Jordan and Einstein frames is exactly the same as in the standard ADM 3+1 decomposition of GR. Finally, we point out that current numerical relativity codes can incorporate the 3+1 evolution equations of metric f(R) gravity by modifying the stress-energy tensor and adding an additional scalar field evolution equation. We hope that this work will serve as a starting point for relativists to develop fully dynamical codes for valid f(R) models.

Planar spring as a mechanical resonator is very important in designing an electrodynamic vibration energy harvesting application (EVEH) to generate output power with high efficiency. Generally, component of the mechanical resonator is a cantilever beam that is designed using one cantilever with an inertial mass placed cantilever tip. In this study, a planar spring which has four arms cantilever beam was designed and fabricated using an extra-thin FR4-PCB material with a total thickness of 130 µm. There are four types of planar spring that were designed and fabricated in this research to produce resonant frequencies at about 30, 40, 50 and 60 Hz with 1 mm width cantilever arm and various length of 13.5, 11.2, 9.8 and 8.7 mm, respectively. FR4 resonator is fabricated using technology LASER-cutting in order to obtain results precisely. The resonant frequency generated by the mechanical resonator is characterized using vibrator system with certain acceleration. The resonant frequency of the planar spring was obtained at a frequency where the maximum induced voltage occurs. The resonant frequency generated by each type of planar spring was obtained at 24.81, 34.24, 40.2, and 46.8 Hz with three conditions of acceleration of 0.02, 0.06, and 0,1g (g=9.8 m/s2).

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.

In this work we investigate the equilibrium configurations of white dwarfs in a modified gravity theory, namely, f(R, T) gravity, for which R and T stand for the Ricci scalar and trace of the energy-momentum tensor, respectively. Considering the functional form f(R, T) = R+2λT, with λ being a constant, we obtain the hydrostatic equilibrium equation for the theory. Some physical properties of white dwarfs, such as: mass, radius, pressure and energy density, as well as their dependence on the parameter λ are derived. More massive and larger white dwarfs are found for negative values of λ when it decreases. The equilibrium configurations predict a maximum mass limit for white dwarfs slightly above the Chandrasekhar limit, with larger radii and lower central densities when compared to standard gravity outcomes. The most important effect of f(R, T) theory for massive white dwarfs is the increase of the radius in comparison with GR and also f(R) results. By comparing our results with some observational data of massive white dwarfs we also find a lower limit for λ, namely, λ > -3 x 10{sup -4}. (orig.)

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.

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

The energy debate raises deep controversies, as discussions on climate change or electricity markets' deregulation show. In this context, it is very difficult for the citizen to express himself in referendums and for the decision maker to slice between various options. Experts themselves deliver controversial evaluations and interest groups can benefit from them to suggest their own solution. This book enables to get a better insight and better understand energy-related controversies and the environmental and socio-economic impacts of energy. It deals with topics as complex and politically extreme as the exhaustion of fossil fuels, climate change, ionising radiations, renewable energy sources, energy consumption in Southern countries and the reorganisation of electricity markets. It starts with an article on the precaution principle and it ends with a glance on the future, devoted to education in the field of efficient energy use [fr

Radiating Fröhlich system as a model of cellular electromagnetism.

Science.gov (United States)

Šrobár, Fedor

2015-01-01

Oscillating polar entities inside the biological cells, most notably microtubules, are bound to emit electromagnetic radiation. This phenomenon is described by Fröhlich kinetic equations expressing, in terms of quantum occupancy numbers of each discrete collective oscillatory mode, the balance between incoming metabolic energy flow and losses due to linear and non-linear interactions with the thermal environs of the oscillators. Hitherto, radiation losses have not been introduced as part of the balance; it was assumed that they were proportional to the modal occupation numbers. It is demonstrated that this formulation is incorrect and the radiation losses must be taken into account in the kinetic equations explicitly. Results of a numerical study of kinetic equations, enlarged in this sense, are presented for the case of three coupled oscillators which was shown to evince the essential attributes of the Fröhlich systems. Oscillator eigenfrequencies were chosen, alternatively, to fall into the MHz and the THz frequency domains. It was found that large radiation levels destroy the main hallmark of the Fröhlich systems, the energy condensation in the lowest frequency mode. The system then functions as a convertor of metabolic energy into radiation. At more moderate radiation levels, both energy condensation and significant radiation can coexist. Possible consequences for the cell physiology are suggested.

We propose, as a novelty in the literature, the modeling of wormholes within a particular case of f(R, T) gravity, namely f(R, T) = R + αR{sup 2} + λT, with R and T being the Ricci scalar and trace of the energy-momentum tensor, respectively, while α and λ are constants. Although such a functional form application can be found in the literature, those concern compact astrophysical objects, such that no wormhole analysis has been done so far. The quadratic geometric and linear material corrections of this theory render the matter content of the wormhole remarkably able to obey the energy conditions. (orig.)

The source composition of the cosmic ray is usually calculated at an energy of a few GeV per nucleon. Recent measurements have however indicated that the source composition may be energy dependent. In order to give a quantitative answer to this question the source composition at 50GeV/nucleon has been calculated using an exponential distribution of path lengths and in the slab approximation. The results obtained at high energy agree very well with the source composition obtained at lower energies, except the abundance of carbon which is significantly lower than the generally accepted value of low energies [fr

In this work, we explore wormhole solutions in f(R, T) theory of gravity, where R is the scalar curvature and T is the trace of stress-energy tensor of matter. To investigate this, we consider a static spherically symmetric geometry with matter contents as anisotropic, isotropic, and barotropic fluids in three separate cases. By taking into account the Starobinsky f(R) model, we analyze the behavior of energy conditions for these different kinds of fluids. It is shown that the wormhole solutions can be constructed without exotic matter in few regions of space-time. We also give the graphical illustration of the results obtained and discuss the equilibrium picture for the anisotropic case only. It is concluded that the wormhole solutions with anisotropic matter are realistic and stable in this theory of gravity. (orig.)

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.

Can renewable energy sources be financed through competitive power markets in the long run?; Koennen sich erneuerbare Energien langfristig auf wettbewerblich organisierten Strommaerkten finanzieren?

Energy Technology Data Exchange (ETDEWEB)

Kopp, Oliver; Essler-Frey, Anke; Engelhorn, Thorsten [MVV Energie AG, Mannheim (Germany)

2012-12-15

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.)

Closed string tachyon driving f(R) cosmology

To study quantum effects on the bulk tachyon dynamics, we replace R with f(R) in the low-energy effective action that couples gravity, the dilaton, and the bulk closed string tachyon of bosonic closed string theory and study properties of their classical solutions. The α' corrections of the graviton-dilaton-tachyon system are implemented in the f(R). We obtain the tachyon-induced rolling solutions and show that the string metric does not need to remain fixed in some cases. In the case with H( t=‑∞ ) = , only the R and R2 terms in f(R) play a role in obtaining the rolling solutions with nontrivial metric. The singular behavior of more classical solutions are investigated and found to be modified by quantum effects. In particular, there could exist some classical solutions, in which the tachyon field rolls down from a maximum of the tachyon potential while the dilaton expectation value is always bounded from above during the rolling process.

The energy supplied to a body in the theory of relativity and the impulse-energy tensor of a compressible fluid

1979-01-01

In the relativity theory, the variation of a certain amount of energy supplied to a body, according to its speed, has been a matter of controversy. We study this variation either for a fluid that is submitted by a compression, or for a gas receiving heat from outward. It is shown that the problem is solved by a simple matter of definition of the energy received in the system of coordinate where the body is moving. Besides, we establish the impulse-energy tensor for a compressible fluid [fr

The Third International Symposium on large TPCs for low-energy rare-event detection was held at Carré des sciences, Poincaré auditorium, 25 rue de la Montagne Ste Geneviève in Paris on 11 12 December 2006. This prestigious location belonging to the Ministry of Research is hosted in the former Ecole Polytechnique. The meeting, held in Paris every two years, gathers a significant community of physicists involved in rare event detection. Its purpose is an extensive discussion of present and future projects using large TPCs for low energy, low background detection of rare events (low-energy neutrinos, dark matter, solar axions). The use of a new generation of Micro-Pattern Gaseous Detectors (MPGD) appears to be a promising way to reach this goal. The program this year was enriched by a new session devoted to the detection challenge of polarized gamma rays, relevant novel experimental techniques and the impact on particle physics, astrophysics and astronomy. A very particular feature of this conference is the large variety of talks ranging from purely theoretical to purely experimental subjects including novel technological aspects. This allows discussion and exchange of useful information and new ideas that are emerging to address particle physics experimental challenges. The scientific highlights at the Symposium came on many fronts: Status of low-energy neutrino physics and double-beta decay New ideas on double-beta decay experiments Gamma ray polarization measurement combining high-precision TPCs with MPGD read-out Dark Matter challenges in both axion and WIMP search with new emerging ideas for detection improvements Progress in gaseous and liquid TPCs for rare event detection Georges Charpak opened the meeting with a talk on gaseous detectors for applications in the bio-medical field. He also underlined the importance of new MPGD detectors for both physics and applications. There were about 100 registered participants at the symposium. The successful

The abundance of galaxy clusters is a powerful probe to constrain the properties of dark energy and gravity at large scales. We employed a self-consistent analysis that includes survey, observable-mass scaling relations and weak gravitational lensing data to obtain constraints on f(R) gravity, which are an order of magnitude tighter than the best previously achieved, as well as on cold dark energy of negligible sound speed. The latter implies clustering of the dark energy fluid at all scales, allowing us to measure the effects of dark energy perturbations at cluster scales. For this study, we recalibrated the halo mass function using the following non-linear characteristic quantities: the spherical collapse threshold, the virial overdensity and an additional mass contribution for cold dark energy. We also presented a new modeling of the f(R) gravity halo mass function that incorporates novel corrections to capture key non-linear effects of the Chameleon screening mechanism, as found in high resolution N-body simulations. All these results permit us to predict, as I will also exemplify, and eventually obtain the next generation of cluster constraints on such models, and provide us with frameworks that can also be applied to other proposed dark energy and modified gravity models using cluster abundance observations.

Combined generation of electric and heating energy in future development of Yugoslav energy sector until 2000

Djajic, Nenad; Zivanovic, Vladimir

2000-01-01

Development of the district heating system in the FR Yugoslavia, beside the combined generation of electric and heating energy presents a necessity for energy, economic and ecological reasons. Although the structure of energy reserves is rather unfavourable considering that the lignite is being predominantly used, available reserves of energy raw material are able to ensure the long-term development of Yugoslav energy sector, and to offer real possibilities for considerable substitution of foreign good quality fuels, especially in district heating systems. Their further development will depend, among other things: on the implementation of new technological solutions for the exploitation of local energy resources; need of reconstruction, revitalisation and transformation of old condensing thermal power plants into the cogeneration plants; installation of remote controlled transmission of heating energy as well as on development of heating plants and smaller co-generation plants based on local energy resources.

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

This paper presents comparison study of simulation and fabrication characterized two type planar springs at micro-fabricated electromagnetic power generator for an ambient vibration energy harvesting system. The power generator utilized a LASER-machined FR4-PCB planar spring, a copper coil, and NdFeB magnet. In order to change resonant frequency, we developed a gimbal suspension structure for the fabrication of spring. The NdFeB permanent magnet was applied as inertial mass. The system was specially designed to harvest low ambient vibrations from 20 to several hundred hertz and low acceleration. The dimension of fabricated energy harvester had 2.5 x 2.5 cm2 in size. In this study we present two different design of cantilever, which is has two and four cantilever, respectively. The different designed given different resonance frequency to the system. The result of simulation giving resonance frequency of two cantilever membrane 22.6 Hz and four cantilever membrane 110.3 Hz. The measurements result has generated 0.135 V with resonance frequency 39 Hz of two cantilever membrane appropriate for human motions, four cantilever membrane has generated 0.174 V with resonance frequency106 Hz appropriate for machine industries.

This statement implies, the definition of a French policy or energy production essentially based on national resources, uranium, and especially for long term, technical know how which allows using plutonium in breeder reactors. This policy implies an effort in R and D, and industrial development of nuclear field, both in reactor construction and at all levels of fuel cycle. This coherent scientific and financial effort has been pursued since the beginning of years 60, and has placed France among the first nuclear countries in the world.

We propose the generalized holographic dark energy model where the infrared cutoff is identified with the combination of the FRW universe parameters: the Hubble rate, particle and future horizons, cosmological constant, the universe lifetime (if finite) and their derivatives. It is demonstrated that with the corresponding choice of the cutoff one can map such holographic dark energy to modified gravity or gravity with a general fluid. Explicitly, F(R) gravity and the general perfect fluid are worked out in detail and the corresponding infrared cutoff is found. Using this correspondence, we get realistic inflation or viable dark energy or a unified inflationary-dark energy universe in terms of covariant holographic dark energy. (orig.)

It has been recently shown that, under some general conditions, it is always possible to find a fourth-order gravity theory capable of reproducing the same dynamics as a given dark energy model. Here, we discuss this approach for a dark energy model with a scalar field evolving under the action of an exponential potential. In the absence of matter, such a potential can be recovered from a fourth-order theory via a conformal transformation. Including the matter term, the function f(R) entering the generalized gravity Lagrangian can be reconstructed according to the dark energy model

Ductile crack growth simulation from near crack tip dissipated energy

International Nuclear Information System (INIS)

Marie, S.; Chapuliot, S.

2000-01-01

A method to calculate ductile tearing in both small scale fracture mechanics specimens and cracked components is presented. This method is based on an estimation of the dissipated energy calculated near the crack tip. Firstly, the method is presented. It is shown that a characteristic parameter G fr can be obtained, relevant to the dissipated energy in the fracture process. The application of the method to the calculation of side grooved crack tip (CT) specimens of different sizes is examined. The value of G fr is identified by comparing the calculated and experimental load line displacement versus crack extension curve for the smallest CT specimen. With this identified value, it is possible to calculate the global behaviour of the largest specimen. The method is then applied to the calculation of a pipe containing a through-wall thickness crack subjected to a bending moment. This pipe is made of the same material as the CT specimens. It is shown that it is possible to simulate the global behaviour of the structure including the prediction of up to 90-mm crack extension. Local terms such as the equivalent stress or the crack tip opening angle are found to be constant during the crack extension process. This supports the view that G fr controls the fields in the vicinity near the crack tip. (orig.)

Generation of spherically symmetric metrics in f(R) gravity

Energy Technology Data Exchange (ETDEWEB)

Amirabi, Z.; Halilsoy, M.; Mazharimousavi, S.H. [Eastern Mediterranean University, Department of Physics, Gazimagusa (Turkey)

2016-06-15

In D-dimensional spherically symmetric f(R) gravity there are three unknown functions to be determined from the fourth order differential equations. It is shown that the system remarkably may be integrated to relate two functions through the third one to provide a reduction to second order equations accompanied with a large class of potential solutions. The third function, which acts as the generator of the process, is F(R) = (df(R))/(dR). We recall that our generating function has been employed as a scalar field with an accompanying self-interacting potential previously, which is entirely different from our approach. Reduction of f(R) theory into a system of equations seems to be efficient enough to generate a solution corresponding to each generating function. As particular examples, besides the known ones, we obtain new black hole solutions in any dimension D. We further extend our analysis to cover non-zero energy-momentum tensors. Global monopole and Maxwell sources are given as examples. (orig.)

2015-01-01

A common approach for understanding people’s domestic energy behavior is to study the influence of deterministic factors, such as attitudes, norms and knowledge, on behavior. However, few studies have succeeded in fully explaining people’s behavior based on these factors alone. To further the understanding of people’s everyday energy use, a goal-oriented approach based on activity theory has been applied to discuss energy conservation from a multiple goal perspective based on the findings fr...

Proton scattering at intermediate energies

International Nuclear Information System (INIS)

Chaumeaux, A.; Layly, V.; Schaeffer, R.

1977-01-01

This article is devoted to the analysis of the most recent Saclay data of elastic and inelastic proton scattering on nuclei at incident energies around 1GeV ( 16 O, the Ca isotopes, the Ni isotopes, 90 Zr and 208 Pb). Various theories (Impulse or Glauber approximation) are comapred. It is shown that the reaction mechanism is very well understood at 1GeV and that, at these energies, absorption and distortion is small enough, so one can extract nuclear densities from the experiment. In particular, the shape of the neutron densities is given, and compared to the Hartree-Fock predictions. The uncertainties, especially in the determination of the neutron radii are discussed [fr

Adipose tissue remodeling in late-lactation dairy cows during feed-restriction-induced negative energy balance.

Excessive rates of demand lipolysis in the adipose tissue (AT) during periods of negative energy balance (NEB) are associated with increased susceptibility to disease and limited lactation performance. Lipolysis induces a remodeling process within AT that is characterized by an inflammatory response, cellular proliferation, and changes in the extracellular matrix (ECMT). The adipose tissue macrophage (ATM) is a key component of the inflammatory response. Infiltration of ATM-forming cellular aggregates was demonstrated in transition cows, suggesting that ATM trafficking and phenotype changes may be associated with disease. However, it is currently unknown if ATM infiltration occurs in dairy cows only during NEB states related to the transition period or also during NEB-induced lipolysis at other stages of lactation. The objective of this study was to evaluate changes in ATM trafficking and inflammatory phenotypes, and the expression of genetic markers of AT remodeling in healthy late-lactation cows during feed restriction-induced NEB. After a 14-d (d -14 to d -1) preliminary period, Holstein cows were randomly assigned to 1 of 2 feeding protocols, ad libitum (AL) or feed restriction (FR), for 4 d (d 1-4). Caloric intake was reduced in FR to achieve a targeted energy balance of -15 Mcal/d of net energy for lactation. Omental and subcutaneous AT samples were collected laparoscopically to harvest stromal vascular fraction (SVF) cells on d -3 and 4. The FR induced a NEB of -14.1±0.62 Mcal/d of net energy for lactation, whereas AL cows remained in positive energy balance (3.2±0.66 Mcal/d of NE L ). The FR triggered a lipolytic response reflected in increased plasma nonesterified fatty acids (0.65±0.05 mEq/L on d 4), enhanced phosphorylation of hormone sensitive lipase, and reduced adipocyte diameter. Flow cytometry and immunohistochemistry analysis revealed that on d 4, FR cows had increased numbers of CD172a + , an ATM (M1 and M2) surface marker, cells in SVF that

High energy radiation detector

International Nuclear Information System (INIS)

1975-01-01

The high energy radiation detector described comprises a set of closely spaced wedge reflectors. Each wedge reflector is composed of three sides forming identical isoceles triangles with a common apex and an open base forming an equilateral triangle. The length of one side of the base is less than the thickness of the coat of material sensitive to high energy radiation. The wedge reflectors reflect the light photons spreading to the rear of the coat in such a way that each reflected track is parallel to the incident track of the light photon spreading rearwards. The angle of the three isosceles triangles with a common apex is between 85 and 95 deg. The first main surface of the coat of high energy radiation sensitive material is in contact with the projecting edges of the surface of the wedge reflectors of the reflecting element [fr

1978-01-01

The history of nuclear energy development in Britain is outlined. Presently three major strategic decisions remain undecided. One is the choice of a thermal reactor type for the steady expansion of nuclear electricity capacity until the end of this century. Another is the reprocessing of spent oxide fuel which at present offers Britain its most promising foreign market. The third one is the future of fast breeders after the successfull demonstration of the 250 MWe prototype reactor at Dounreay [fr

Rational approximations of f(R) cosmography through Pad'e polynomials

Science.gov (United States)

Capozziello, Salvatore; D'Agostino, Rocco; Luongo, Orlando

2018-05-01

We consider high-redshift f(R) cosmography adopting the technique of polynomial reconstruction. In lieu of considering Taylor treatments, which turn out to be non-predictive as soon as z>1, we take into account the Pad&apose rational approximations which consist in performing expansions converging at high redshift domains. Particularly, our strategy is to reconstruct f(z) functions first, assuming the Ricci scalar to be invertible with respect to the redshift z. Having the so-obtained f(z) functions, we invert them and we easily obtain the corresponding f(R) terms. We minimize error propagation, assuming no errors upon redshift data. The treatment we follow naturally leads to evaluating curvature pressure, density and equation of state, characterizing the universe evolution at redshift much higher than standard cosmographic approaches. We therefore match these outcomes with small redshift constraints got by framing the f(R) cosmology through Taylor series around 0zsimeq . This gives rise to a calibration procedure with small redshift that enables the definitions of polynomial approximations up to zsimeq 10. Last but not least, we show discrepancies with the standard cosmological model which go towards an extension of the ΛCDM paradigm, indicating an effective dark energy term evolving in time. We finally describe the evolution of our effective dark energy term by means of basic techniques of data mining.

Energy dissipation of slot-type flip buckets

Wu, Jian-hua; Li, Shu-fang; Ma, Fei

2018-03-01

The energy dissipation is a key index in the evaluation of energy dissipation elements. In the present work, a flip bucket with a slot, called the slot-type flip bucket, is theoretically and experimentally investigated by the method of estimating the energy dissipation. The theoretical analysis shows that, in order to have the energy dissipation, it is necessary to determine the sequent flow depth h 1 and the flow speed V 1 at the corresponding position through the flow depth h 2 after the hydraulic jump. The relative flow depth h 2 / h 。 is a function of the approach flow Froude number Fr 。, the relative slot width b/B 。, and the relative slot angle θ/β. The expression for estimating the energy dissipation is developed, and the maximum error is not larger than 9.21%.

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

.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.

Dark energy from modified gravity with Lagrange multipliers

International Nuclear Information System (INIS)

Capozziello, Salvatore; Matsumoto, Jiro; Nojiri, Shin'ichi; Odintsov, Sergei D.

2010-01-01

We study scalar-tensor theory, k-essence and modified gravity with Lagrange multiplier constraint which role is to reduce the number of degrees of freedom. Dark Energy cosmology of different types (ΛCDM, unified inflation with DE, smooth non-phantom/phantom transition epoch) is reconstructed in such models. It is demonstrated that presence of Lagrange multiplier simplifies the reconstruction scenario. It is shown that mathematical equivalence between scalar theory and F(R) gravity is broken due to presence of constraint. The cosmological evolution is defined by the second F 2 (R) function dictated by the constraint. The convenient F(R) gravity sector is relevant for local tests. This opens the possibility to make originally non-realistic theory to be viable by adding the corresponding constraint. A general discussion on the role of Lagrange multipliers to make higher-derivative gravity canonical is developed.

Design and Analysis of the Power Control System of the Fast Zero Energy Reactor FR-0

This report describes the power control by means of the fine-control rod and the design of the control system of the fast zero energy reactor FR-0 located in Studsvik, Sweden. System requirements and some operational conditions were used as design criteria. Manual and automatic control is possible. Variable electronic end-stops for the control rod have been designed, because of the special construction of the reactor and control rod. Noise in the control system caused by the reactor, detector and electronics caused disturbances of the control system at the lower power levels. The noise power-spectrum was measured. Statistical design methods, using the measured noise power spectrum, were used to design filters, which will reduce the influence of the noise at the lower power levels. Root Loci sketches and Bode diagrams were used for stability analyses. The system was simulated on an analogue computer, taking into account even nonlinearities of the control system and noise. Typical cases of reactor operation were simulated and stability analysis performed.

An Advanced Energy System (AES) with nuclear reactors as an energy source has been proposed which supply electricity and heat to cities. The AES has three objectives: 1. Save energy resources and reduce green house gas emissions, attaining total energy utilization efficiency higher than 85% through waste heat recovery and utilization. 2. Foster a recycling society that produces methane and methanol for fuel cells from waste products of cities and farms. 3. Consume TRU produced in LWRs as fuel for FRs, and reduce long-lived radioactive wastes or environmental loads of long term geological disposal. References 1. Y. Kato, T. Nitawaki and K.

The first observation of the prompt and the delayed γ transitions involving the high spin states in 210 Fr is reported. The decay of the high spin states and the isomeric levels of 210 Fr, identified for the first time from the known sequence of low-lying transitions found earlier in the α decay of 214 Ac, were studied. High spin states of the doubly-odd 210 Fr, which were produced by the fusion evaporation reaction 197 Au ( 16 O, xn) 213-x Fr, were populated and the subsequent emitted γ rays were detected through the high-sensitivity germanium clover detector array INGA. The level scheme up to yrast levels of 5.3 MeV excitation energy and ∼20(ℎ/2π) angular momentum could be established for the first time through γγ, γγΔT coincidence, and DCO ratio measurements. A new low-lying isomeric transition at E γ = 203(2) keV was observed. The half-life was measured to be T 1/2 = 41(2) ns. The measured half-life was compared with the corresponding single-particle estimate, based on the level scheme obtained from the experiment.

The energy calibration and precision of a gamma spectrometry unit - Method using the electron annihilation energy as the only standard

International Nuclear Information System (INIS)

Hoclet, Michel

1971-06-01

Spectrometry using Ge(Li) detectors is discussed. The excellent resolution of this type of detector, the mathematical analysis of the spectral lines of the pulses, and the reproducibility of the spectrometer enable highly accurate measurements of the abscises (some 10 -5 ) corresponding to the peaks. A method using the annihilation energy of the electron as the only standard was developed. The method is applied to the measurement of the gamma ray energies of the radioelements: 22 Na, 24 Na, 56 Mn, 56 Co, 59 Fe, 72 Ga, 88 Y, 122 Sb, 124 Sb and 137 Cs. (author) [fr

In the present paper we generate a set of solutions describing the interior of a compact star under f(R, T) theory of gravity which admits conformal motion. An extension of general relativity, the f(R, T) gravity is associated to Ricci scalar R and the trace of the energy-momentum tensor T. To handle the Einstein field equations in the form of differential equations of second order, first of all we adopt the Lie algebra with conformal Killing vectors (CKV) which enable one to get a solvable form of such equations and second we consider the equation of state (EOS) p = ωρ with 0 < ω < 1 for the fluid distribution consisting of normal matter, ω being the EOS parameter. We therefore analytically explore several physical aspects of the model to represent behavior of the compact stars such as - energy conditions, TOV equation, stability of the system, Buchdahl condition, compactness and redshift. It is checked that the physical validity and the acceptability of the present model within the specified observational constraint in connection to a dozen of the compact star candidates are quite satisfactory.

Results experimentally obtained from jets of E(p)=10-10 3 GeV in nuclear emulsion show that the target nucleus in proton-nucleus collisions seems to present ''limiting fragmentation''. In the same energy range, proton-nucleus collisions resemble closely proton-proton collisions and asymmetric shape of rapidities is only caused by the break-up products of heavy targets [fr

Economic evaluation of innovative storage technologies in energy systems with a high share of renewable energies; Oekonomische Bewertung von innovativen Speichertechnologien in Energiesystemen mit einem hohen Anteil erneuerbarer Energien

Energy Technology Data Exchange (ETDEWEB)

Kondziella, Hendrik

2017-04-13

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.

Energy in the strategy to Sahel development : Situation- Perspectives- Recommendations

International Nuclear Information System (INIS)

1978-10-01

Energy plays an important role in the development of the Sahel Countries. For instance, in these countries, the use of wood fire is essential as a source of energy. However, the increase in the wood supply leads to environmental problems; hence the necessity for the states to promote alternative source of energy to replace the wood. Used in the field of agriculture, transport, industry and construction, energy in Sahel countries hurts to financial problems such as difficulties in the funding of oil import and supply security. It is then indispensable to develop energy resources in the Sahel countries. Energy policies must emphasize on hydroelectric energy, nuclear energy and also better reorganize certain sources of energy such as gas, oil, and coal. Thus this political assumption of responsibility through a comprehensive approach will contribute to generate the development of the Sahel countries [fr

Fast liberation of energy stored using superconductors

International Nuclear Information System (INIS)

Prost, G.; Sole, J.

1967-01-01

After a rapid description of the circumstances in which they first thought of using superconducting materials for the storage and liberation of energy, the authors examine, in comparison to condensers, the energy densities which can thus be stored, the methods used for introducing this energy into the superconducting circuit and for trapping it, and the law governing the discharge of this energy into a purely dissipative impedance. This leads to a derivation of the expression for the energy yield which depends on the characteristics of the switch used for opening the superconducting circuit. An experimental study has been made of a superconducting switch with a view to understanding the various parameters. As a result of this analysis, transitions of this switch, over the whole of its mass, were obtained for periods of a few microseconds, and energy yields close to unity were obtained. The obtention of fast discharges is now no longer a technological problem. (authors) [fr

2012-01-01

Magnetic characterization of creep-fatigue damage for welded specimens of austenitic stainless steel (SUS316FR) and high-chromium steel (Mod.9Cr-1Mo) steel was performed using magnetic force microscope and Hall sensor. In SUS316FR volume fraction of δ-ferrite at weld metal region decreased by creep or creep-fatigue and the remanent magnetic flux density at weld metal region also decreased. In Mod.9Cr-1Mo steel magnetic characteristics at weld metal region were different from those at base metal initially, however, during creep or creep fatigue the difference of magnetic characteristics between welded metal and base metal became small. It was found that the degradation mechanism for these energy structural materials during creep or creep fatigue could be clarified by magnetic characterization techniques. (author)

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.

Exact solutions for scalar field cosmology in f(R) gravity

Maharaj, S. D.; Goswami, R.; Chervon, S. V.; Nikolaev, A. V.

2017-09-01

We study scalar field FLRW cosmology in the content of f(R) gravity. Our consideration is restricted to the spatially flat Friedmann universe. We derived the general evolution equations of the model, and showed that the scalar field equation is automatically satisfied for any form of the f(R) function. We also derived representations for kinetic and potential energies, as well as for the acceleration in terms of the Hubble parameter and the form of the f(R) function. Next we found the exact cosmological solutions in modified gravity without specifying the f(R) function. With negligible acceleration of the scalar curvature, we found that the de Sitter inflationary solution is always attained. Also we obtained new solutions with special restrictions on the integration constants. These solutions contain oscillating, accelerating, decelerating and even contracting universes. For further investigation, we selected special cases which can be applied with early or late inflation. We also found exact solutions for the general case for the model with negligible acceleration of the scalar curvature in terms of special Airy functions. Using initial conditions which represent the universe at the present epoch, we determined the constants of integration. This allows for the comparison of the scale factor in the new solutions with that for current stage of the universe evolution in the ΛCDM model.

The first renewable marine energy projects were first presented during the so called Eole program in 1996, and then during a call for bids on offshore wind-power in 2004. Despite these initiatives and a second call for bids in 2011, only a few prototypes are being tested at the beginning of 2013. This study aims to determine if the French legislation is adapted to this emerging new activity of renewable marine energy installation implementation. The results of three-year research show that several advances have contributed to defining a legal framework favorable to the implementation of renewable marine energy production installation; yet, their legal regime has not been finalized. Nevertheless, a comparison with maritime and coastal legislations reveals solutions are worth considering and possible. As a result, an intervention from legislative or parliamentary authorities seems necessary to simplify the implementation of projects and to limit the risks of legal disputes [fr

Electron energy distribution in a weakly ionized plasma

International Nuclear Information System (INIS)

Cesari, C.

1967-03-01

The aim of this work is to determine from both the theoretical and experimental points of view the type of distribution function for the electronic energies existing in a positive-column type cold laboratory plasma having an ionization rate of between 10 -6 and 10 -7 . The theoretical analysis, based on the imperfect Lorentz model and taking into account inelastic collisions is developed from the Boltzmann equation. The experimental method which we have employed for making an electrostatic analysis of the electronic energies makes use of a Langmuir probe used in conjunction with a transistorized electronic device. A comparison between the experimental and theoretical results yields information concerning the mechanisms governing electronic energy transfer on a microscopic scale. (author) [fr

Detection system with a large angular acceptance and an energy high dynamics, for heavy ion physics at intermediate energies: M.E.ω. detector

International Nuclear Information System (INIS)

Monnet, F.

1985-01-01

Built for intermediate energy heavy ions nuclear physics, the M.E.ω. detector uses various and complementary detection methods: ionization chamber, parallel plate avalanche counter, plastic scintillators. With these techniques, velocity, energy, mass and charge of nuclei were measured over wide range. From the detailed theoretical study of each method, limitations and perturbation causes are deduced. The solutions used for optimizing the detector, and the main results are exposed. The internal sectorisation of the detector, which permits a modulation in counting rate and electronical adjustments, has been revealed to be very suitable for heavy ions intermediate energy physics. Results of the first experiment realised with M.E.ω. (Ar + Ag at 35 MeV/u) are commented [fr

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.

Distinguishing modified gravity from dark energy

International Nuclear Information System (INIS)

Bertschinger, Edmund; Zukin, Phillip

2008-01-01

The acceleration of the Universe can be explained either through dark energy or through the modification of gravity on large scales. In this paper we investigate modified gravity models and compare their observable predictions with dark energy models. Modifications of general relativity are expected to be scale independent on superhorizon scales and scale dependent on subhorizon scales. For scale-independent modifications, utilizing the conservation of the curvature scalar and a parametrized post-Newtonian formulation of cosmological perturbations, we derive results for large-scale structure growth, weak gravitational lensing, and cosmic microwave background anisotropy. For scale-dependent modifications, inspired by recent f(R) theories we introduce a parametrization for the gravitational coupling G and the post-Newtonian parameter γ. These parametrizations provide a convenient formalism for testing general relativity. However, we find that if dark energy is generalized to include both entropy and shear stress perturbations, and the dynamics of dark energy is unknown a priori, then modified gravity cannot in general be distinguished from dark energy using cosmological linear perturbations.

Energy and acceptability

International Nuclear Information System (INIS)

Gueron, Jules

1980-01-01

The controversy focusing on nuclear energy extends well beyond factual questions, whether with respect to the technology itself or the information of the public concerning it. A whole ensemble of political, economic, social and moral problems are raised on this occasion, only too frequently implicitly. Some authors put forward a social psycho-analysis of the situation, others keep to the analysis and refutation of the opposing theses or even do not hesitate to make use of the counter attack, not to mention, indulging in abuse. There are also those who, without concealing their own tendencies, assume a pedagogical approach and so one finds (sometimes under the same heading) the reasons for opposition to or approval of nuclear energy. The appreciation of the facts mingles with their description. Faced with such a choice of wealth -or lack of it- the reader finds it difficult to form his own judgment. The considerations unfolded in this article will perhaps help him to do so [fr

Non-Resonant Magnetoelectric Energy Harvesting Utilizing Phase Transformation in Relaxor Ferroelectric Single Crystals

Directory of Open Access Journals (Sweden)

Peter Finkel

2015-12-01

Full Text Available Recent advances in phase transition transduction enabled the design of a non-resonant broadband mechanical energy harvester that is capable of delivering an energy density per cycle up to two orders of magnitude larger than resonant cantilever piezoelectric type generators. This was achieved in a [011] oriented and poled domain engineered relaxor ferroelectric single crystal, mechanically biased to a state just below the ferroelectric rhombohedral (FR-ferroelectric orthorhombic (FO phase transformation. Therefore, a small variation in an input parameter, e.g., electrical, mechanical, or thermal will generate a large output due to the significant polarization change associated with the transition. This idea was extended in the present work to design a non-resonant, multi-domain magnetoelectric composite hybrid harvester comprised of highly magnetostrictive alloy, [Fe81.4Ga18.6 (Galfenol or TbxDy1-xFe2 (Terfenol-D], and lead indium niobate–lead magnesium niobate–lead titanate (PIN-PMN-PT domain engineered relaxor ferroelectric single crystal. A small magnetic field applied to the coupled device causes the magnetostrictive element to expand, and the resulting stress forces the phase change in the relaxor ferroelectric single crystal. We have demonstrated high energy conversion in this magnetoelectric device by triggering the FR-FO transition in the single crystal by a small ac magnetic field in a broad frequency range that is important for multi-domain hybrid energy harvesting devices.

The stochastic energy-Casimir method

Arnaudon, Alexis; Ganaba, Nader; Holm, Darryl D.

2018-04-01

In this paper, we extend the energy-Casimir stability method for deterministic Lie-Poisson Hamiltonian systems to provide sufficient conditions for stability in probability of stochastic dynamical systems with symmetries. We illustrate this theory with classical examples of coadjoint motion, including the rigid body, the heavy top, and the compressible Euler equation in two dimensions. The main result is that stable deterministic equilibria remain stable in probability up to a certain stopping time that depends on the amplitude of the noise for finite-dimensional systems and on the amplitude of the spatial derivative of the noise for infinite-dimensional systems. xml:lang="fr"

Bone X-ray absorptiometry using two energies

International Nuclear Information System (INIS)

Laval-Jeantet, A.M.; Laval-Jeantet, M.; Bloch, J.

1979-01-01

A method of X-ray absorptiometry using two energies (28 and 36 keV) as a means of determining mineralisation of a bone specimen is described. The ratio of coefficients determined at the different energies varies according to the total mineralisation of the bone studied. A model, representing a serie of bone specimens constructed to study this relationship is described. The coefficients of attenuation for a given wavelength were measured. The relation between the coefficients found at two energies for a given specimen of known mineral content was found to vary as a function of the mineralisation. It is possible to determine the coefficient of attenuation characteristic of a bone and hence its mineralisation and thickness by measurements at two different wavelengths using this function. Experimental results show this potential of the method, but also its high sensitivity to small measurements errors [fr

Out of these three compound nuclei, 213Fr is a shell closed (N=126 compound nucleus and the other two are away from the shell closure. From a comparison of the experimental fission cross-sections with the statistical model predictions, it is observed that the fission cross-sections are underestimated by the statistical model predictions using shell corrected finite range rotating liquid drop model (FRLDM fission barriers. Further the FRLDM fission barriers are reduced to fit the fission cross-sections over the entire measured energy range.

Any energy recovery, even partial, goes in the direction of savings in energy and should be sought for. The Tricastin plant, now in the course of being built, will be able to deliver several hundreds of MW for the purpose of urban and agricultural heating. The new Coredif project will more completely integrate the valorization of calories in its definition (choice of temperatures, design of the heat exchangers, recovery cycles). In fact the recent evolution in energy costs renders the otpimization of a plant equipped with a heat recovery system (1 to 2% on the cost of the uranium produced) now economically worth-while. In the same way, the choice of the site of the future plant may be conditioned by the possible uses of calories in its vicinity [fr

A number of underground stores have been developed in recent years in Denmark. The development has been subsidised with funds of `Development program renewable energy` launched by the Danish Ministry for Environment and Energy. First experience reports on underground storage show that more emphasis must be put on the development of storage sealing and cover construction. Hence research works currently focuses on the investigation of liner material and further development of floating cover constructions. The target is the development of underground storage using solar energy for heating that can compete with conventional heating systems technically and economically. (orig.)

The renewable energy sources have in the last ten years - not only in Germany, but also worldwide - can post disproportionately strong growth rates. This is especially true in the electricity production. Especially the new renewable energies have a stable, strong growth and gain as compared to the conventional generation ever more ground. Nevertheless, hydropower remains by far the most important source of renewable energy in electricity generation. An analysis shows that hydropower can make significant contributions to sustainable and climate-friendly energy supply by 2050, if it is possible to raise their still unused potential. [German] Die erneuerbaren Energien haben in den letzten zehn Jahren - nicht nur in Deutschland, sondern auch weltweit - ueberproportional starke Zuwachsraten verbuchen koennen.

Trotzdem ist die Wasserkraft unveraendert die mit Abstand bedeutendste erneuerbare Energiequelle in der Stromerzeugung. Eine Analyse zeigt, dass die Wasserkraft bis 2050 signifikante Beitraege zu einer nachhaltigen und klimaschonenden Energieversorgung leisten kann, wenn es gelingt, ihre noch ungenutzen Potenziale zu heben.

Hydro-power, biomass fuel, solar photovoltaic and wind power, are the renewable energy sources that Reunion island (Indian Ocean, FR) is developing to manage the security of its electric power system. In 2009, power generation reached 2618 GWh and was ensured at 67% by imported fossil fuels (47% coal and 20% hydrocarbons) and at 33% by renewable energies (20% hydraulic, 20% bagasse and 2% solar, wind and biogas). Total production capacity of the island reaches 625 MW. The average power used is of about 330 MW. Private companies supply 60% of the production and the remaining 40% are supplied by EdF who owns about 330000 clients. The average consumption of a Reunion inhabitant is 1259 kWh per year (2330 kWh/y for a metropolitan French). (J.S.)

Given the outlook for hydrocarbon depletion, three primary energy sources could enable supplies to be diversified, i.e. nuclear energy, coal and solar energy. These primary energy sources can rarely be used directly and must be converted into energy carriers such as electricity, hydrogen, substitute natural gas, liquid hydrocarbons derived from coal, etc. The nature of future gas carriers and their position in the national energy balance must be examined. Within the framework of an overall energy pattern. Many of the potential conversion processes are often interrelated through their production and consumption. Likewise, seasonal variations in consumption make it necessary to design production plants for peak demand or to create large-scale storage facilities. An initial model taking these interactions into consideration has been worked out to represent the variety of solutions possible. This model can be used to evaluate the technical paths to be followed within the framework of different assumptions concerning the future [fr

As regards electricity, the program lead to a transformation of production modes, manifested by an increased call upon nuclear energy and coal leading in turn to major consequences on costs. The competivity of electricity offers it the promise of strong penetration at the consumption level, but this should tend towards more rational utilizations and ones more adaptable to the new price structures. The industry could profit from the evolution now under way to improve its international competivity [fr

In this paper, we have analyzed the stability of cylindrically symmetric collapsing object filled with locally anisotropic fluid in f(R, T) theory, where R is the scalar curvature and T is the trace of stress-energy tensor of matter. Modified field equations and dynamical equations are constructed in f(R, T) gravity. The evolution or collapse equation is derived from dynamical equations by performing a linear perturbation on them. The instability range is explored in both the Newtonian and the post-Newtonian regimes with the help of an adiabatic index, which defines the impact of the physical parameters on the instability range. Some conditions are imposed on the physical quantities to secure the stability of the gravitating sources. (orig.)

Knowledge from the low energy results

Before being used at very high energies, in order to search for the quark-gluon plasma, nucleus-nucleus central collisions have been studied at low energy, between about 20 MeV per nucleon and 10 GeV per nucleon, with the same objective to explore the phase diagram of nuclear matter, but in a regime where both temperature and energy are too small for plasma formation. Approaching this very complicated problem of nuclear physics led to many difficulties. They are first reviewed, and various means developed in order to solve them are considered. These difficulties are then detailed along discussions about temperature and nuclear collective flow. Temperature is a concept which is commonly used but also a quantity which is difficult to measure. Nuclear collective flow is a very interesting compression effect; it has been observed experimentally after being predicted theoretically, but its interpretation in terms of the nuclear matter equation of state remains quite difficult [fr

Microanalysis by spectroscopy of transmitted electron energy losses

International Nuclear Information System (INIS)

Colliex, C.; Trebbia, P.

1978-01-01

Among the various signals which, in a transmission electron microscope, result from the interactions between the primary beam of well defined energy E 0 and the sample, the spectrum of the energy distribution of the electrons transmitted contains useful informations on the chemical and physical properties of the sample. Consequently the adaptation of an energy dispersive system on an electron microscope enables new fields of research to be investigated, particularly a localised chemical analysis technique with a space resolution scale equal to that of the electron microscope. It is this second aspect that we suggest describing in particular here. Already, this technique appears to be indispensable in the problems arising from the analysis of very small quantities of matter: detection limits in the order of 10 -19 to 10 -20 g (around 100 to 1000 atoms) would seem to be resonably possible [fr

Nuclear Energy Data 2013

International Nuclear Information System (INIS)

2013-01-01

Nuclear Energy Data is the OECD Nuclear Energy Agency's annual compilation of statistics and country reports documenting the status of nuclear power in the OECD area. Information provided by member country governments includes statistics on installed generating capacity, total electricity produced by all sources and by nuclear power, nuclear energy policies and fuel cycle developments, as well as projected generating capacity and electricity production to 2035, where available. Total electricity generation at nuclear power plants and the share of electricity production from nuclear power plants declined in 2012 as a result of operational issues at some facilities and suspended operation at all but two reactors in Japan. Nuclear safety was further strengthened in 2012 following safety reviews prompted by the Fukushima Daiichi nuclear power plant accident. Governments committed to maintaining nuclear power in the energy mix pursued initiatives to increase nuclear generating capacity. In Turkey, plans were finalised for the construction of the first four reactors for commercial electricity production. Further details on these and other developments are provided in the publication's numerous tables, graphs and country reports. This publication contains 'Statlinks'. For each StatLink, the reader will find a URL which leads to the corresponding spreadsheet. These links work in the same way as an Internet link [fr

World supply of nuclear energy

International Nuclear Information System (INIS)

Pecqueur, Michel.

1981-01-01

At the end of 1980 nuclear energy accounted for 9% of the world production of electricity stemming from 262 power stations, utilising mainly the process of water reactors and representing an installed capacity of 142 GWe. This production, apparently limited, already represents the equivalent of 150 million TOE. The 600 nuclear power stations in service, under construction or ordered represent a total of 450 GWe. In 1985, their production ought to cover 15% of the world requirements of electricity, which corresponds to a doubling of the share of nuclear energy within 6 years. During these recent years, the development of nuclear energy has undergone a significant slowing down and the number of orders for new nuclear power stations has dropped considerably in particular in the United States. Considering the time required and the available industrial capacity, the accumulated capacity which could be installed worlwide by 1990 could attain 530 GWe, equivalent to 650 MTOE covering 24% of the world production of electricity and 7% of the world consumption of primary energy. A determined effort for the end of this century could end up by the installation of 1200 GWe of capacity, generating 1.5 GTOE. The share of nuclear energy would then represent 35% of the production of electricity [fr

This paper aims to explore some realistic configurations of anisotropic spherical structures in the background of metric f(R) gravity, where R is the Ricci scalar. The solutions obtained by Krori and Barua are used to examine the nature of particular compact stars with three different modified gravity models. The behavior of material variables is analyzed through plots and the physical viability of compact stars is investigated through energy conditions. We also discuss the behavior of different forces, equation of state parameter, measure of anisotropy and Tolman-Oppenheimer-Volkoff equation in the modeling of stellar structures. The comparison from our graphical representations may provide evidence for the realistic and viable f(R) gravity models at both theoretical and the astrophysical scale. (orig.)

Study of Neutron-Deficient $^{202-205}$Fr Isotopes with Collinear Resonance Ionization Spectroscopy

CERN Document Server

De Schepper, Stijn; Cocolios, Thomas; Budincevic, Ivan

The scope of this master’s thesis is the study of neutron-deficient $^{202−205}$Fr isotopes. These isotopes are inside the neutron-deficient lead region, a region that has shown evidence of shape coexistence. For this thesis, this discussion is limited to the phenomenon where a low lying excited state has a different shape than the ground state. Shape coexistence is caused by intruder states. These are single-particle Shell Model states that are perturbed in energy due to the interaction with a deformed core. In the neutron-deficient lead region the main proton intruder orbit is the 3s$_{1/2}$orbit. When going towards more neutron-deficient isotopes, deformation increases. The $\\pi3s_{1/2}$orbit will rise in energy and will eventually become the ground state in odd- A bismuth (Z=83) isotopes. It is also observed in odd-A astatine (Z=85) isotopes, already in less neutron-deficient nuclei. The same phenomenon is expected to be present francium (Z=87) isotopes already at $^{199}$Fr. Although it is currently ...

Diesel engine cogeneration plants in the context of integration of renewable energy sources in power supply; Dieselmotor-Kraft-Waerme-Kopplungsanlagen im Kontext der Integration Erneuerbarer Energien in die Energieversorgung

Energy Technology Data Exchange (ETDEWEB)

Sievers, John

2010-10-29

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

The energy spectrum of the α particles emitted in the thermal neutron induced fission of 235 U was measured from 11.5 MeV down to 2 MeV using the parabola mass spectrometer Lohengrin at the ILL high flux reactor. A Monte Carlo program, that simulates the α particle motion to the spectrometer, has been developed. Numerical results of Monte Carlo calculations for differents values of parameter are reported. The overall energy spectrum is slightly asymmetric at low energy. The possible reasons for the existence of this asymmetry are discussed [fr

Flow with vibrational energy exchange, application to CO2 electric laser

International Nuclear Information System (INIS)

1974-01-01

The performances of a continuous wave (CO 2 , N 2 , He) laser ionized by an electron beam are calculated. Several types of phenomena are considered: energy exchange processes between molecules of laser medium, electron molecular excitation processes, aerodynamic phenomena: the energy exchanges accompanying the laser effect generate important quantities of heat, which have to be evacuated by the flow. After a survey of the fundamental assumptions on molecular phenomena, a computer code was developed for following, along the flow, the evolution of the thermodynamic parameters (pressure, temperature), of the laser gain, and of the electrical properties (electron density and temperature). To provide a finer description of the last ones, a model giving the energy distribution of the electrons in the laser medium was established [fr

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.

The contribution of safety issues to public perceptions of energy systems

International Nuclear Information System (INIS)

Otway, H.J.; Thomas, Kerry

1978-01-01

Public opposition is an important consideration for those responsible for energy planning. An attitude model was applied to identify the underlying determinants of public perceptions of five energy systems: nuclear, coal, oil, solar and hydro. Empirical results are reported in which these energy systems were found to be perceived in terms of four basic dimensions: psychological aspects; economics benefits; socio-political implications; environmental and physical safety issues. For the total sample, safety issues made an appreciable contribution to attitudes toward all of the systems except nuclear energy, where it was not significant. A differential analysis of two sub-samples, those respondents PRO and CON nuclear energy, showed that benefits and safety issues were important determinants of PRO attitudes while CON attitudes were primarily due to psychological aspects and concerns about personal and political power. The role of technical information in the formation of public attitudes toward technological policies is discussed [fr
