  1. Prospects for hydrogen in the German energy system

    The focus of the paper concerns the current discussion on the contribution of the hydrogen economy to a 'sustainable energy system'. It considers whether advantages for the environmental situation and energy carrier supply can be expected from the already visible future characteristics of hydrogen as a new secondary energy carrier. Possible production paths for hydrogen from hydrocarbon-based, renewable or carbon-reduced/-free primary energy carriers are evaluated with respect to primary energy use and CO 2 emissions from the fuel cycle. Hydrogen has to be packaged by compression or liquefaction, transported by surface vehicles or pipelines, stored and transferred to the end user. Whether generated by electrolysis or by reforming, and even if produced locally at filling stations, the gaseous or liquid hydrogen has to undergo these market processes before it can be used by the customer. In order to provide an idea of possible markets with special emphasis on the German energy sector, a technical systems analysis of possible hydrogen applications is performed for the stationary, mobile and portable sector. Furthermore, different 'business as usual' scenarios are analysed for Germany, Europe and the World concerning end energy use in different sectors. The very small assumed penetration of hydrogen in the analysed scenarios up to the year 2050 indicates that the hydrogen economy is a long-term option. With reference to the assumed supply paths and analysed application possibilities, hydrogen can be an option for clean energy use if hydrogen can be produced with carbon-reduced or -free primary energy carriers like renewable energy or biomass. However, the energetic use of hydrogen competes with the direct use of clean primary energy and/or with the use of electric energy based on renewable primary energy. As a substitution product for other secondary energy carriers hydrogen is therefore under pressure of costs and/or must have advantages in comparison to the use of

    In Germany, energy shift has now caused that a quarter of the total consumed power is obtained from renewable energy sources. There, a shift from nuclear energy has been achieved, and the dissemination of renewable energy as industrial creation has been demanded. However, the Renewable Energy Act, which was the promoter of the above process, was revised drastically in August 2014. Although evaluation on the revised Renewable Energy Act is a future work, it is said that this revision is quite severe for the parties who have promoted the renewable energy business in local regions and enjoyed the profiles locally. Regarding electricity, the German government has a strong industrial protection policy. This paper summarized the basic stance of the German government, by taking up the specific examples of actual electricity fee and the reduction/exemption system of levies on power consumption type companies. The German government clearly shows its willingness to adhere to be an industrial nation. In Germany, the wholesaling spot price of electricity declined due to the spread of renewable energy. This also comes from the mechanism of the FIT system. Unlike Germany where FIT system started in 2000, levies are still small affecting less in Japan where the FIT system has just begun. However, in Germany, it is a big problem. In order to discuss the ideal way of FIT system in Japan, it is necessary to know as accurately as possible what the reality is, including about overseas precedents. (A.O.)

  5. Managing the resilience space of the German energy system - A vector analysis.

    2018-07-15

    The UN Sustainable Development Goals formulated in 2016 confirmed the sustainability concept of the Earth Summit of 1992 and supported UNEP's green economy transition concept. The transformation of the energy system (Energiewende) is the keystone of Germany's sustainability strategy and of the German green economy concept. We use ten updated energy-related indicators of the German sustainability strategy to analyse the German energy system. The development of the sustainable indicators is examined in the monitoring process by a vector analysis performed in two-dimensional Euclidean space (Euclidean plane). The aim of the novel vector analysis is to measure the current status of the Energiewende in Germany and thereby provide decision makers with information about the strains for the specific remaining pathway of the single indicators and of the total system in order to meet the sustainability targets of the Energiewende. Within this vector model, three vectors (the normative sustainable development vector, the real development vector, and the green economy vector) define the resilience space of our analysis. The resilience space encloses a number of vectors representing different pathways with different technological and socio-economic strains to achieve a sustainable development of the green economy. In this space, the decision will be made as to whether the government measures will lead to a resilient energy system or whether a readjustment of indicator targets or political measures is necessary. The vector analysis enables us to analyse both the government's ambitiousness, which is expressed in the sustainability target for the indicators at the start of the sustainability strategy representing the starting preference order of the German government (SPO) and, secondly, the current preference order of German society in order to bridge the remaining distance to reach the specific sustainability goals of the strategy summarized in the current preference order (CPO

  6. Cost efficient utilisation of biomass in the German energy system in the context of energy and environmental policies

    2011-01-01

    The possible uses of biomass for energy provision are manifold. Gaseous, liquid and solid bioenergy carriers can be alternatively converted into heat, power or transport fuel. The contribution of the different utilisation pathways to environmental political targets for greenhouse gas (GHG) emission reduction and energy political targets for the future share of renewable energy vary accordingly to their techno-economic characteristics. The aim of the presented study is to assess the different biomass options against the background of energy and environmental political targets based on a system analytical approach for the future German energy sector. The results show that heat generation and to a lower extent combined heat and power (CHP) production from solid biomass like wood and straw are the most cost effective ways to contribute to the emission reduction targets. The use of energy crops in fermentation biogas plants (maize) and for production of 1st generation transportation fuels, like biodiesel from rapeseed and ethanol from grain or sugar beet, are less favourable. Optimisation potentials lie in a switch to the production of 2nd generation biofuels and the enhanced use of either biomass residues or low production intensive energy crops. - Research Highlights: → Heat generation and CHP generation from biomass can contribute cost efficiently to emission reduction targets. → Biofuel production represenst the least cost efficient option for emission reduction when using biomass energetically. → The energetical use of biomass shows a high potential to contribute to energy and envirnoment political targets.

    2017-09-01

    Full Text Available European energy system is undergoing a deep transition to low-emission energy sources, mainly wind farms. This transition is caused mostly by energy politics of European Union (EU and its goals in the topic of renewable energy. European wind energy is dominated by Germany that produces half of total wind energy in EU. The aim of this article is to present support systems for wind farms existing in Germany in the context of introducing in Poland the Act of 20 May 2016 on Wind Energy Investments limiting onshore wind farms localization and Act of 22 June 2016 introducing changes to the Act on Renewable Energy Sources (RES and some other acts. It is postulated to make amendments of acts regulating RES while considering German solutions.

    In the framework of the Intersolar Europe 2012 exhibition, the French-German office for Renewable energies (OFAEnR) organised a conference on photovoltaic energy and the transformation of the French-German energy systems. During this French-German exchange of experience, participants exchanged views on the increasing integration of renewable energies to power grids, and on the necessity to develop new energy management and business models for projects financing. This document brings together the available presentations (slides) made during this event: 1 - System integration of PV in Germany and France: Comparing results of the ReS Integration Study (Jan-Benjamin Spitzley, Filip Jirous); 2 - The role of solar PV in France: current status and development opportunities (Xavier Daval); 3 - The European project PV GRID and the relevance of PV in the European power system (Thomas Chrometzka); 4 - Business Models beyond the EEG Act. When feed-in tariffs are no longer sufficient: what project financing models for solar power plants in France and Germany? (Herbert Muders)

    In 2014 the German government's primary goal of engaging German power suppliers to step up their production of renewable energy while speeding up energy efficiency improvement measures continued to dominate the debate. The present article provides an updated overview of the German energy market. Following on from last year's edition it gives a condensed synopsis of key indicators of the energy economy. Besides summarising general facts about the energy mix it goes into detail about the following individual energy resources: crude oil, natural gas, brown coal, hard coal, nuclear energy and renewable energies. It also explains current price trends in both the international and domestic markets.

  11. Evolution of the German energy policy

    The author first recalls the main events and decisions regarding the German policy from 1998 to 2011, and notably the decisions related to nuclear energy. He gives the main data of the German energy system (production capacity, production of the different primary sources) and indicates the main characteristics and assumptions of the 2011 turnaround (decision of shutting down 17 nuclear plants by 2022, objectives in terms of renewable energy production and share, of electricity consumption, and of greenhouse gas emission). The author then presents how the law on renewable energies (EEG) operates, indicates energy prices in Germany for individuals and industries and CO 2 emissions per electric sector, and compares them with the French ones. He outlines the need of construction of new energy transport lines, and identifies and comments other implications of the intermittent character of renewable energies in terms of electricity market organisation, of construction of combustion-based thermal plants, and of flexibility requirements. He discusses successes and difficulties of this evolution of energy policy, and the implication of this new policy for the European Union and for border countries

    Since the publication of the draft ''Climate Protection Plan 2050'' and the ''Green Paper on Energy Efficiency'', it is clear that the Federal Government is focusing on the electrification of the heat and transport sector in order to increase the share of renewable energies in these sectors. This step is not uncontroversial, and represents a paradigm shift in science and politics, because the reduction of the cross electricity consumption move into the background. It is now necessary to clearly distinguish between the conventional power consumption, which must continue to be tested for energy savings and efficiency potential, and the new power consumption, here referred to as the coupling current, which is accepted in order to achieve the objectives of the energy transition. Since the consideration of the energy transition as a purely national project is too short, possible positive and negative effects of the European Union Emission Trading System (EU ETS) deserve particular attention with regard to this reorientation.

  13. Hydrogen as a link between sustainable mobility and transition of the German energy system

    2013-06-01

    Even 15 years ago, the predictions with regard to the market penetration of fuel cell automobiles or of so-called fuel cell heaters were communicated with differing statements. Daimler Benz AG, as it still was back then, had put their faith in the rapid integration of a fuel cell into the vehicle, whereas companies such as Vaillant, Hamburger Gas Consult, Sulzer Hexis or even MTU and Siemens were working on stationary fuel cell systems. The expectations at that time with regard to market and technology development have still not yet been fulfilled. Today, the subject has been given a new lease of life thanks to the public discussions regarding the energy transition and the current framework conditions. Many concepts that have already been under consideration, but which very few have considered realistic in the short-term, now appear at least to have come within reach. As a result of the fluctuations in the generation of renewable energies, Germany needs loads that can be switched and, above all, methods of storing energy. In conjunction with new technologies, such as PEM electrolysis and the pressure which has been put on politics to react and to create the necessary framework conditions, a new momentum has developed with regard to the use of hydrogen. This article analyses to what extent synergies between energy transition and mobility can be expected within the context of hydrogen. With a view to quantity, times and local relationships, quality and price, we have been able to determine that the relevant amounts and dependencies have a positive and relevant magnitude to one another, thus synergies are present. It should be noted that hydrogen will not be the sole solution for the Federal Government when it comes to achieving CO{sub 2} reduction aims. Electrical mobility with approaches for bidirectional charging, new storage technologies and alternative energy carriers, switchable loads as well as the local public transport systems and new mobility concepts will

  14. The system of legal regulations and supervisory powers in the German Atomic Energy Law

    International Nuclear Information System (INIS)

    Weber, K.H.

    1984-01-01

    The first part of the book deals with the practical implementation of the legal provisions governing examination and subsequent licensing and judicial restraint, and the effects of actual practice on the energy industry, for the purpose of showing the chain of cause and effect of the frequently lamented delays in the further utilisation of nuclear energy, and of analysing the role of the administrative courts in the process, pointing to the explosiveness in terms of economics of this issue. The second part analyses the risk assessments from the legal and technical point of view in order to ascertain whether the findings of risk assessments are suitable to serve as scale models for decisions to be taken by the courts. The third part is a critical evaluation of the numerous attempts to incorporate the general doctrine of discretionary power into the system of atomic energy law in a way conformable with the existing system. This analysis resulting in the statement that the attempts have failed so far, the fourth part of the book discusses the necessity to look for other solutions, among other things by critically screening the dogma of discretionary power. The author comes to the conclusion that judicial restraint is to be cut back in the licensing procedure, however not to the extent that control over the authorities is abandoned altogether, but rather in such a way that the power of administrative courts does not develop into judgments executing the law. It is to be avoided that licensing procedures for nuclear power plants degenerate into 'administrative procedures preceded by administrative procedures'. This may not be confounded with giving up all possibilities of legal protection. (orig./HSCH) [de

Ausgehend davon werden die Moeglichkeiten und Grenzen einer weitergehenden Wasserkraftnutzung im Energiesystem Deutschland diskutiert. (orig.)

  17. German energy policy in deregulated Europe

    International Nuclear Information System (INIS)

    Kuhnt, D.

    2000-01-01

    The author argues in favor of a more fact-oriented German energy policy: Firstly, German energy policy must accept the new European framework of a market economy. This means that German utilities must no longer be burdened with the implementation of political objectives. The German power industry needs a level playing field for competition on a European scale. Consequently, also the European partner countries should not limit themselves to the minimum conditions of the Single Market Directive in opening their markets. Secondly, German energy policy must develop new forms of cooperation with the power industry so as to maintain domestic employment and the addition of value despite considerably stronger competitive pressure. Also the conflicting targets of sustainability, continuity of supply, and economic viability must not only be discussed, but must be turned into productive approaches. Thirdly, this means that there must be no inadmissible solution in matters nuclear. If the German power industry is to remain strong, in the interest of domestic jobs and opportunities for the future, it must not lose any more domestic market share to other European companies. Fourthly, we need a new energy policy which takes cognizance of the results of market development in a more rational, less emotional way. In this respect, it should be limited henceforth to supporting renewable energies and technologies so as to enhance energy efficiency in line with market requirements. Fifthly, German energy policy must not commit the mistake of enforcing deregulation and, at the same time, exempting large segments of the market from competition. Thus, the planned expansion of renewable energies, and the increase in cogeneration to more than thirty percent of the German electricty generation, by way of quotas and revenues for electricity from these sources fed into the public grid, are incompatible with competition in Europe. The electricity tax within the framework of the eco tax, the

He is further of the opinion that the expansion of nuclear energy - in spite of internal political difficulties - will continue in the long term. Hence breeders and reconditioning will become realities. For German foreign policy this means that it must also carry responsibilities on a global scale in this respect. (orig.) [de

    The book presents a comprehensive and systematic account of the concept, the current status and the costs of the German energy transition: the Energiewende. Written by an insider who has been working in the German energy industry for over 20 years, it follows a strictly non-political, neutral approach and clearly outlines the most relevant facts and figures. In particular, it describes the main impacts of the Energiewende on the German power system and Germany's national economy. Furthermore, it addresses questions that are of global interest with respect to energy transitions, such as the cost to the national economy, the financial burden on private households and companies and the actual effects on CO{sub 2} emissions. The book also discusses what could have been done better in terms of planning and implementing the Energiewende, and identifies important lessons for other countries that are considering a similar energy transition.

    2001-01-01

    This contribution is a comprehensive analysis of EC law on state aid and resulting possible impacts on the German legal system for the energy sector. The analysis reveals that, depending on the legal interpretation of Art. 87 of the EC Treaty, further non-compliance issues such as that currently under debate in connection with German legislation supporting market penetration of electricity from renewable energy sources, may arise in the future. Further examples referred to are the German system of liability reserves for the decommissioning of nuclear power plants, and the system of third party liability for nuclear power plant operators. The author addresses various problem areas and uses characteristic examples in explaining conceivable matters of conflict. (orig./CB) [de

  4. Is the German energy transition sustainable?

    International Nuclear Information System (INIS)

    Beeker, Etienne; Godot, Clelia

    2012-09-01

    In 2011, Germany began a radical energy policy, or 'Energiewende', with the aim of completely abandoning nuclear power by 2022 and then achieving an 80-95% reduction in the country's greenhouse gas emissions by 2050. By this date, the country will therefore have to be producing its electricity almost completely without the use of gas, oil and coal, having replaced 80% of these sources with renewable energies. Germany is a rich country with one of the most competitive industries in the world. Its environmental commitments have been clearly stated and Energiewende, which is widely discussed throughout the country, has so far seen strong support from the population, despite the expected increases in the price of electricity which, however, is already almost twice as expensive as in France. Germany therefore seems to hold the winning cards required to successfully implement its energy transition. However, many difficulties need to be overcome if this energy policy is to succeed, such as the development of the national power grid, the cost and financing of the necessary investments, improved electricity storage techniques, the acceptability of the planned increases in the price of electricity or the financial difficulties experienced by solar panel manufacturers as a result of the sharp reduction in subsidies and competition from Asia. In addition, recent political dissent within the government regarding the measures implemented to achieve its stated goal has slowed down the federal decision-making process on this matter. Finally, Germany's decision is not without consequences for its European neighbours. It is upsetting and weakening the supply and demand balance of the European energy system and putting some operators in a difficult position. The eyes of all energy world observers are therefore riveted on the changes taking place in Germany, because they will have significant consequences for the entire European Union, and even beyond.

  5. German Atomic Energy Act turns fifty

    2009-01-01

    The German Atomic Energy Act entered into force on January 1, 1960. It turns fifty at the beginning of 2010. Is this a reason to celebrate or rather the opposite? Lawyers, in principle, can view old pieces of legislation from 2 perspectives: On the one hand, aged laws are treated in a spirit of veneration and are celebrated as proven. On the other hand, an anniversary of this kind can be a welcome reason for demands to abolish or, at least, fundamentally renew that law. Over the past half century, the German Atomic Energy Act went through stormy and varied phases both of a legal and a political character. Its 50 th anniversary is likely to spark off very conflicting evaluations as well. A review of legal history shows that the German or, rather, the Federal German Atomic Energy Act (AtG) was not a first-of-its-kind piece of legislation but stemmed from the 1957 EURATOM Treaty, in a way representing a latecomer of that treaty. The Atomic Energy Act experienced a number of important developments throughout its history: - In 1975, compulsory licensing of fuel element factories was introduced. - The back end of the fuel cycle, especially final storage, were incorporated in the Atomic Energy Act comprehensively first in 1976. - In 1985, legislators decided in favor of unlimited nuclear liability. - In 1994 and 1998, only some innovations in special items were introduced under the headings of environmental impact assessment and suitability for repository storage because the controversy about nuclear power did not permit a fundamental alignment towards a more comprehensive modern safety law. - The decision to opt out of the peaceful uses of nuclear power in 2002 drew the final line so far of decisions about directions of nuclear law in a major amendment. In parallel, the decisions by the Federal Constitutional Court and the Federal Administrative Court in the late 1970s and, above all, the 1980s provided important assistance which has remained valid to this day.

    As Germany has decided to phase out nuclear by 2022 while aiming at ambitious objectives in terms of energy savings and reduction of greenhouse gas emissions, this report first highlights the interest of such an energy transition. It discusses the immediate consequences of the shutting down of the first eight reactors. It gives an overview of the German energy mix and discusses the objectives and challenges of the energy policy, and how this policy is implemented (by restructuring the electric grid, by building flame-based thermal power stations, by searching for a solution for electricity mass storage, by creating the conditions of an efficient energy saving policy). It discusses the consequences of this policy for the European and French energy policy

    This study examines the long-memory properties of German energy price indices (specifically, import and export prices, as well as producer and consumer prices) for hard coal, lignite, mineral oil and natural gas adopting a fractional integration modelling framework. The analysis is undertaken using monthly data from January 2000 to August 2011. The results suggest nonstationary long memory in the series (with orders of integration equal to or higher than 1) when breaks are not allowed for. However, endogenous break tests indicate a single break in all series except for producer prices for lignite for which two breaks are detected. When such breaks are taken into account, and with autocorrelated disturbances, evidence of mean reversion is found in practically all cases.

  10. Promoting the market and system integration of renewable energies through premium schemes—A case study of the German market premium

    2013-01-01

    With the share of renewable energies within the electricity sector rising, improving their market and system integration is of increasing importance. By offering plant operators a premium on top of the electricity market price, premium schemes represent an option to increase the alignment of renewable electricity production with market signals, and have been implemented by several EU member states. This paper examines the case study of the German market premium scheme adopted in 2012. Building on an evaluation of early experiences, we discuss whether the market premium contributes to the aims of market and/or system integration (effectiveness), and what potential efficiency gains and additional costs of “administering integration” are associated with it (efficiency). While exposing renewables to price risks is not the scheme’s purpose, it has successfully increased participation in direct marketing. However, risks of overcompensating producers for marketing and balancing costs are high, and the benefits of gradually leading plant operators towards the market are questionable. Incentives for demand-oriented production are established, but they seem insufficient particularly in the case of intermittent renewable energy sources. To conclude, we provide an outlook on alternative designs of premium schemes, and discuss whether they seem better suited for addressing the challenges ahead. - Highlights: • Premium schemes are used to align renewable energy sources (RES) with market signals. • We examine the effectiveness and efficiency of the German market premium scheme. • Participation in direct marketing has increased, but so have support costs. • For intermittent RES, incentives for demand-oriented production are insufficient. • Efficiency gains from exposing RES to market risks entail several trade-offs

    2017-06-01

    Full Text Available During the last two decades renewable sources of energy as an environmentally friendly alternative to fossil fuel energy have gained more and more importance within the German electricity system. Their share has increased from less than 4 % to roughly one third of the gross electricity production in the last 25 years. Against this background, the goal of this paper is to present briefly the current status of the use of renewables within the German electricity system, to assess selected developments taking place during this development process as well as to identify given challenges and needs as well as necessary actions to pave the road for a further use of renewable sources of energy within the German electricity provision system. The political driver for the latter is the overarching goal to reduce Greenhouse Gas (GHG emissions which has been confirmed within the Paris agreement signed by the end of 2015.

  13. Major energy users and reforms of the German energy industry

    Energy Technology Data Exchange (ETDEWEB)

    1994-06-01

    There is a historic tradition of industrial autoproduction of electricity in Germany. Major energy users in the past used to be and today often still are autoproducers of electric power. The public utility sector, according to present legal standards, operates in a framework that protects local and regional monopolies. The large consumers and autoproducers are an important countervailing power in the whole system of the electricity supply industry. Electric utilities (EU) in Germany are semi-public or private enterprises of a wide variety of size. The large producer utilities operate the high voltage grid on the basis of private contracts. Regional distribution companies mostly without a considerable share in production often in cooperation with local distributors deliver electricity (el) in the non-urban areas whereas mostly city owned EU supply the large cities often on the basis of considerable parts of autoproduction and often also with a considerable share of el produced in cogeneration plants. The equilibrium between the parts of this system in the past was ensured by a legal framework protecting local monopolies as well as long term contracts between producers and distributors. Deregulation trends inherent in European legislation on competition have threatened this stability. In the first phase resistance against a more competitive order seemed unanimous. In the meantime however the different actors had time to rethink their position: The European Council has now proposed a more moderate regulation. The German Government has made a proposal for some important changes in the Energy Law and connected passages in the Competition Law, which would introduce some more competitive elements into the system without anticipating the results of a competitive process.

    Since the publication of the draft ''Climate Protection Plan 2050'' and the ''Green Paper on Energy Efficiency'', it is clear that the Federal Government is focusing on the electrification of the heat and transport sector in order to increase the share of renewable energies in these sectors. This step is not uncontroversial, and represents a paradigm shift in science and politics, because the reduction of the cross electricity consumption move into the background. It is now necessary to clearly distinguish between the conventional power consumption, which must continue to be tested for energy savings and efficiency potential, and the new power consumption, here referred to as the coupling current, which is accepted in order to achieve the objectives of the energy transition. Since the consideration of the energy transition as a purely national project is too short, possible positive and negative effects of the European Union Emission Trading System (EU ETS) deserve particular attention with regard to this reorientation. [German] Spaetestens seit der Veroeffentlichung des Entwurfs zum ''Klimaschutzplan 2050'' und des ''Gruenbuch Energieeffizienz'' ist klar, dass die Bundesregierung auf die Elektrifizierung des Waerme- und Verkehrssektors setzt, um den Anteil der erneuerbaren Energien in diesen Sektoren zu steigern. Dieser Schritt ist nicht unumstritten und stellt einen Paradigmenwechsel in Wissenschaft und Politik dar, denn auf einmal rueckt die Senkung des Bruttostromverbrauchs in den Hintergrund. Es gilt jetzt, klar zu trennen zwischen dem herkoemmlichen Stromverbrauch, der weiterhin auf Energieeinspar- und -effizienzpotenziale hin untersucht werden muss, und dem neuen, hier Koppelstrom genannten Stromverbrauch, welcher in Kauf genommen wird, um die Ziele der Energiewende zu erreichen.

    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 purpose of this paper is to describe the nature of medical care within the German penal system. German prison services provide health care for all inmates, including psychiatric care. The reached level of equivalence of care and ethical problems and resource limitations are discussed and the way of legislation in this field since 2006 reform on federal law is described. The article summarizes basic data on German prison health care for mentally ill inmates. The legislation process and factors of influence are pointed out. A description of how psychiatric care is organized in German prisons follows. It focuses on the actual legal situation including European standards of prison health care and prevention of torture, psychiatric care in German prisons themselves, self harm and addiction. Associated problems such as blood born diseases and tuberculosis are included. The interactions between prison staff and health care personal and ethic aspects are discussed. The legislation process is still going on and there is still a chance to improve psychiatric care. Mental health problems are the major challenge for prison health care. Factors such as special problems of migrants, shortage of professionals and pure statistic data are considered. The paper provides a general overview on psychiatric services in prison and names weak points and strengths of the system.

    Taking into account the strategic and economic stakes that are associated with the security of energy supplies, the German federal government has made of this question one of the priorities of its european presidency. In this note, the author observes a radical change in the German energy policy with the future phaseout of nuclear energy and the perspectives of Russian gas supply. The author also reviews the challenges of the elaboration of a European energy policy, with certain member States refusing to transfer their sovereignty in the energy domain, and the large split between national requirements and community exigencies in this field

    The author gives a brief survey on the short, but relatively successful story of nuclear energy in the Federal Republic of Germany (FRG). Like many other countries, FRG had to go through a very difficult period of political indecision and violent opposition from antinuclear groups, supported by large parts of the media. The licensing procedures have been streamlined, nuclear power plants are being built without major interference, and the FRG is making good progress in closing the fuel cycle. This means that nuclear power will play an important role in the energy supply system, although on a lower level than originally anticipated

    The energy consumption of industry and private households in a country is closely linked with the amount and development of the GNP and the available income. Instead of extrapolations, a dynamic econometric model was developed based on the Keynesian theory and the data of 1960 to 1974 relating to national accounts. The economic ties between Baden--Wuertemberg and the FRG are to be insured by a subsequent coupling to an FRG model. The first part of this paper basically deals with the fundamentals of the model. An introduction to the problems given by the project is followed by the theoretical economic conception and methodical bases of the model, as well as a discussion of various possible versions of behavior equations. From a set of possible versions of a behavior equation one version, possibly with an alternative for the model simulation in the second part, is selected.

    The energy consumption of industry and private households in a country is closely linked with the amount and development of the GNP and income available. Instead of extrapolations, a dynamic econometric model was developed based on the Keynesian theory and the data of 1960 to 1974 relating to national accounts. The economic ties between Baden--Wuerttemberg and the FRG are to be ensured by a subsequent coupling of the FRG-model. In the second part of this paper the equations selected in the first part are checked due to revised basic data, and a complete set of equations is combined as a model. The behavior of this model is tested by comparing simulation results with basic data and by means of a regulative theoretical stability analysis. While the simulation data repeat the course of the GNP and the available income sufficiently precise, yields, private capital investments and the unemployment ratio are superimposed with larger variations. The stability analysis proved a model behavior to be oscillatory stable.

    The regional conference was devoted to the legal problems that ensue from German reunification against the background of the integration of German atomic energy law within international law. The elements of national atomic energy legislation required by international law and recent developments in international nuclear liability law were discussed from different perspectives. The particular problems of the application of the German Atomic Energy Act in the 5 new Laender (the territories of the former GDR) were presented and discussed, namely: The continued validity of old licences issued by the GDR; practical legal problems connected with the construction of nuclear power plants in the 5 new Laender; the legal issues connected with the final repository for radioactive wastes at Morsleben; and the new developments in radiation protection law following from the Unification Treaty and the new ICRP recommendations. All 14 lectures have been abstracted and indexed individually. (orig.) [de

    Significant reduction of CO 2 -emissions is essential in order to prevent a worsening of ongoing climate change. This thesis analyses two different pathways for the mitigation of CO 2 -emissions in electricity generation. It focuses on the calculation of CO 2 -mitigation costs of renewable energy sources (RES) as well as of power plants with carbon capture and storage (CCS). Under the frame of long-term CO 2 reductions targets for the German electricity sector future CO 2 -mitigation costs are calculated on a system-based and a technology-based approach. The calculations show that RES have lower system-based mitigation costs in all scenarios compared to a system based on CCS. If the retrofit of power plants is taken into consideration, the results are even more clearly in favour of RES. Further, the thesis investigates whether CCS can serve as a bridge towards a sustainable energy system based on RES. Findings of different scientific disciplines suggest that CCS is not the optimal choice. These findings lead to the conclusion that CCS cannot support an easier integration of RES. CCS rather has the potential to further strengthen the fossil pathway and delaying the large-scale integration of RES. Hence, CCS is rather unsuited as a bridging technology towards a system mainly based on RES.

    The given basic orientation of the energy concept of the federal government for the German energy supply increased towards renewable energy while increasing energy efficiency determines the market trend. In the present case, a current overview of the German energy market will be given of this year providing a concentrated compilation of the central main features of the energy industry. As in previous years, the article summarizes not only general facts about the energy, but also goes in detail on the development of the individual fuels such as oil, natural gas, lignite and hard coal, nuclear energy and renewable energies. Furthermore, the price trends are described in the international markets and in the domestic market.

    Full Text Available The article deals with the description and analysis of functioning of the German national system of economic diplomacy. The author provides a brief summary of historical and economic background, stages and conditions of its development from the 1950-s to present time. He casts light upon the procedures and mechanisms of interaction between the key national economic-diplomatic agents i.e. ministries, agencies, other authorized bodies, public and private institutes outlining their usage of concrete economic, administrative and legal instruments in the course of respective policy measures. The author looks into the distinctive features which encompass the essence of the model: a two-level system with three pillars: foreign representations of the MFA, Germany Trade and Investment Agency, chambers of commerce. The above elements do not overlap each other's functions, but complement them; their functioning is based upon interministeriality and the single window concept. A special focus is made on the practice of economic-diplomatic agents, especially chambers of commerce, using private public partnership instruments. In general, notwithstanding recurring negative trends of the domestic and global business climate (oil crisis in the 1970-s, recession of the late 2000s - early 2010s the German economy demonstrated of high resistibility to exogenous shocks compared to other economies and according to the absolute values of its macroeconomic indicators. Alongside other economic and noneconomic factors this stability can to a certain extent be explained by an efficient system of economic diplomacy. Established in the 1970s it keeps on evolving in order to stand up to new challenges. At any stage of the business cycle it constitutes a pillar of the German economy and, ultimately, of the economy of the European Union.

  10. Mid-point review of the German energy transition

    Lauer, H.; Safa, H.; Guidez, J.

    2017-01-01

    The result of the 2015 review of the German energy transition is lukewarm. First: generating 20 % of the electricity production through wind power and solar energy appears to be very costly in Germany. Secondly there is practically no effect on the reduction of CO_2 releases as coal has been re-introduced to play the role of nuclear energy which was carbon-free to counter-balance the intermittency of renewable energies. Thirdly a necessity to keep all thermal plants ready to operate in order to cope with the intermittency of renewable energies as no adequate means of energy storage is available, appears to be a luxury that only Germany can afford. And fourthly, the cost of electric power for households and small enterprises is all the higher as the government economic policy is to spare German electro-intensive industry. One of the side effects of the German energy transition policy is to disturb the European market of electricity when favourable climate conditions make green electricity very abundant. In this situation electricity prices drop sharply and can even become negative while green electricity is always paid to the producer at a steady price guaranteed by the state. (A.C.)

    With the aim of reducing greenhouse gas emissions, comprehensive climate protection measures have already been adopted both nationally and internationally. This raises the question of how economically and ecologically useful system infrastructure looks, which at the same time ensures the supply reliability of all consumers. The regenerative energy model (REMod) presented in this book has been developed to provide answers. The sectors electricity, heat, transport and industry are considered for the first time simultaneous in an energy system model. In particular, in order to satisfy the criterion of reliability of supply, the model calculates the energy flows in hourly resolution for the period from today (2015) to 2050. The system is optimized with regard to minimum overall costs and under the boundary condition that a maximum set quantity of permitted greenhouse gas emissions is not exceed. On the example of Germany (REMod-D), the results show that, in particular, the interaction of the sectors can lead to strong differences in the design of the system infrastructure. [German] Mit dem Ziel den Ausstoss der Treibhausgase zu reduzieren, wurden bereits national wie international umfangreiche Klimaschutzmassnahmen verabschiedet. Hieraus ergibt sich die Frage wie eine oekonomisch und oekologisch sinnvolle Systeminfrastruktur aussieht, die gleichzeitig die Versorgungssicherheit aller Verbraucher gewaehrleistet. Das in diesem Buch vorgestellte Regenerative Energien Modell (REMod) wurde entwickelt um hierauf Antworten zu liefern. Beruecksichtigt werden erstmalig in einem Energiesystemmodell die Sektoren Strom, Waerme, Verkehr und Industrie gleichzeitig. Insbesondere um dem Kriterium der Versorgungssicherheit gerecht zu werden, berechnet das Modell die Energiefluesse in stuendlicher Aufloesung fuer den Zeitraum von heute (2015) bis 2050. Optimiert wird das System hinsichtlich minimaler Gesamtkosten und unter der Randbedingung, dass eine maximal vorgegebene Menge erlaubter

    2016-01-01

    COP21 is the cornerstone for the decarbonization of energy markets globally: for the first time a commitment for the reduction of GHG emissions was reached on a global level. Although the national emission reduction contributions (INDC) don't yet fulfill a 2 degree of C path, they mark a big move in mind set for the need of emission reduction to limit climate change. But how can this goal be reached while sustaining energy supply security and affordability of energy. Germany is a pioneer in terms of a radical change of national energy system, but is the German 'Energiewende' a blue-line print for energy transition in general? Germany has made big progress in the installation of renewables esp. Wind and Solar PV. Installed capacity for Wind and Solar power reached more than 80 GW in 2015, but new installations esp. for Solar PV have significantly slowed down in the recent past after some years of record installation of 7-8 GW per year in 2010-2012. With the growing share of fluctuating renewables such and wind and solar PV the system integration became an issue. There are huge differences in Wind and Solar PV installations between the North and South of Germany. Peaks in power generation either from Wind or Solar can't be operated within the regions anymore. While the transmission line from North to South are missing and construction is substantially delayed, the temporary regional oversupply is managed more or less by power flows into neighbouring countries. Beside the technical aspects there are also economic issues. Despite significant cost reduction for renewables the EEG levy is continuously growing. Due to the regional imbalances the efforts for redispatch of conventional power plants are increasing and thereby the cost for system balance. The share of levies and taxes on retail electricity prices is above 50 percent since some years. So far the policy failed to limit the increase of retail electricity prices but affordability of energy became a greater

    An estimated 15.7 million Germans are currently practicing yoga or are at least interested in starting to practice, and they often perceive yoga as a therapeutic approach. From a healthcare system perspective, the situation is less clear. Here, yoga is only recognized as a recreational or preventive activity. When yoga teachers fulfill specific qualifications, their preventive yoga classes are covered by the statutory health insurances. Only those with additional qualifications in medicine or psychotherapy, however, can independently use and promote "yoga therapy." The general perception of yoga in Germany as a preventive practice is reflected in the professional organization of yoga providers. Most providers are considered to be yoga teachers rather than yoga therapists and are organized mainly in yoga teacher associations. Despite the uncertain legal framework, yoga is now considered in a number of medical guidelines; in a number of hospitals, yoga is part of multimodal inpatient treatment programs and is delivered by physical therapists or members of other health professions. An increasing number of yoga therapy clinical trials are conducted in Germany, and efforts are underway to establish yoga therapy as an accepted adjunct treatment approach for selected medical conditions within the German healthcare system.

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

    1982-01-01

    The liability of operators of nuclear installations in the FRG is limited under current law to the sum of one thousand million DM (section 31 of the Atomic Energy law). Since about the autumn of 1979, the Federal Ministry of the Interior is making inquiries into the necessity and appropriateness of abandoning the provision on liability limitations, in order to improve the victims compensation. The legal problems involved in this decision are presented by the author, trying to answer the question of whether the current system of liability limitations should be maintained or abandoned by discussing this issue from the point of view of the legal functions ''justice'' and ''expedience'' of this provision. The manifold international interlacement of the atomic energy law does not allow this study to be restricted to the law of the FRG. A brief review of the development and current state of the international nuclear liability law is the basis of this study into the problems of a possible modification of the German nuclear liability provisions. The study is carried out with the purpose of elaborating model solutions. (orig./HP) [de

    The German Federal Government pledged itself to make a 25% reduction in national CO{sub 2} emissions by 2005 on the basis of 1990 CO{sub 2} emissions. This reduction target is valid for the entire Federal Republic. Within that context the Federal Ministry of Education, Science, Research and Technology initiated the IKARUS project (Instruments for Greenhouse Gas Reduction Strategies) in 1990. The aim of the project is to provide tools for developing strategies to reduce energy-related emissions of greenhouse gases in Germany. A range of instruments has been developed consisting of models, a data base and various tools with the aid of which different action sequences can be simulated and evaluated until the year 2020. By using the database and mainly one of the models of the project a scenario in terms of energy and carbon dioxide emissions will be sown as it could be expected for the year 2005. For this scenario as base two different strategies that hit the 25% reduction target will be discussed. Special attention is given to the transport sector. (au)

    The simultaneous implementation of the German 'Energiewende' and the French 'Transition energetique' prompted both country's governments to sign various cooperation agreements. As both 'Energiewende' and 'Transition energetique' put a strong focus on decentralization of energy supply, establishing close inter-communal cooperation is particularly promising. The project TANDEM, which is jointly led by Klima-Buendnis and Energy Cities - both local authority networks - and co-funded by Germany's Federal Environment Agency (UBA) and the French Energy Agency ADEME provides French and German local authorities with a unique opportunity to exchange experiences and create partnerships for climate protection having the following objectives: - Creating broad mutual understanding for the respective situation, challenges and framework in energy and climate policy; - Encourage exchanges with regard to obstacles and success factors concerning the realization of ambitious energy- and climate-goals and promoting mutual transfer of know-how; - Stimulating close collaboration between local authorities from both countries while involving and supporting local stakeholders and citizens; - Implementing initial stages of cooperation projects during the lifetime of the TANDEM project and creating a foundation for long-term cooperation; - Raise awareness for demands, requirements and concerns of local authorities on a national and European level in order to strengthen their influence and enlarge their scope of action. In this document, the authors briefly present the French, German and European contexts and the organization of both countries regarding energy transition. Then, a parallel is made between the national energy-climate plans of both countries ('Klimaschutzkonzepte' and 'Plans Climat-Energie Territoriaux') to identify the similarities and differences in order to learn from each other and to be able to create cooperations between both policy mechanisms

  20. Profitability of Management Systems on German Fenlands

    Full Text Available Fens are organic sites that require drainage for agricultural use. Lowering the groundwater level leads to trade-offs between economic benefits and environmental impacts (i.e., CO2 and nutrient emissions. To identify management options that are both environmentally and economically sustainable, a propaedeutic systematic analysis of the costs, income and profit of different land use and management systems on fenlands is necessary. This study provides an overview of the profitability, labor demand and comparative advantages of feasible management systems on German fenlands. Twenty management practices in four land use systems are analyzed. The results indicate that most management systems are profitable only with subsidies and payments for ecosystem services. In addition to sales revenue, these payments are indispensable to promote peat-saving agricultural practices on fenlands. Regarding the labor aspect, intensive management systems caused an increase in working hours per hectare, which may positively affect employment in rural areas. The calculations obtained in this study can be used as a basis for estimations of greenhouse gas (GHG mitigation costs when management systems are associated with GHG emission values.

    The German EnWG (energy industry law) for deregulation of the energy sector and implementation of the Internal Energy Market Directive of the EU contains an obligation to contract and make rules for establishing a legally binding system for access to and use of third parties of transmission and distribution networks in the competitive electricity market. The design of such contracts under private law as well as the grid code for network operation primarily being a matter of the contracting parties, the legal basis and opportunities for governmental supervisory functions are embodied in various laws. The legal analysis of this contribution examines the current situation and asks whether the existing provisions of the German BGB (Civil Code), antitrust law and the EnWG offer practicable means in case of need for governmental supervisory action in order to ensure evolution and adherence to a legal framework that will ensure the objectives of the politically willed deregulation of the energy sector and foster development of an open market serving the public welfare.

  2. German energy transition at the crossroad: global pressures or green energy island

    International Nuclear Information System (INIS)

    Umbach, Frank

    2015-05-01

    In reaction to the March 2011 nuclear disaster that occurred in Fukushima/Japan, Germany has unilaterally decided to launch an energy transition of hitherto unseen dimensions. Berlin set extremely ambitious objectives such as phasing out nuclear energy by 2020, as well as, in the long run, the creation of a sustainable and autarkic energy system. Reactions to this decision differed. Within her own country, Angela Merkel's energy transition was largely acclaimed, although it represented a total u-turn with respect to the previous policy which consisted of prolonging nuclear reactors' lifespan. Abroad and notably among Germany's European partners, it has, in turn, been heavily criticized. These partners had not been consulted prior to decisions being taken, despite the huge impact these decisions had and continue to have on their own energy security. Four years after Angela Merkel announced the German energy transition, it is obvious that a lot of effort still needs to be put into it and that the objectives defined are far from having been reached. German energy policy has failed to adapt to its global context, notably characterized by the U.S. shale gas revolution, geopolitical upheaval, the great polluters' absent willingness to commit to climate protection, etc. At the time being, it has also failed to find a sustainable equilibrium between environmental protection, energy security and economic competitiveness. Moreover, Germany needs to act in accordance with its European partners, without whom it will not be able to tackle the global challenge of climate change and attain to European energy security. If Germany fails to reach these objectives, it may see its competitiveness and geopolitical influence decline at the global level, which would also have repercussions on the EU's standing in the world.

    2017-08-01

    This article proposes an overview of the German situation regarding the implementation of its energy transition policy (Energiewende) which mainly comprised phasing out nuclear and fossil energies, and their replacement by renewable energies. The authors notably comment figures and tables which illustrate the evolution of greenhouse gas emissions in Germany, France and Europe, the evolution of wind and photovoltaic installations in Germany, the status of the energy mix and the shares of renewable energies in primary consumption in Germany and in France, the electricity productions from the different sources in Germany and in France, the structure of electric power tariffs in Germany and in France. Focusing on the German case, they outline that the objectives defined for 2020 for renewable energies are almost reached, but what comes next remains uncertain. They also notice that the objective of phasing out nuclear in 2022 is kept. They discuss the various difficulties faced by the Energiewende: a too slow improvement of energy efficiency, a development of electric vehicles facing realities of the automotive industry, a difficult but necessary phasing out coal. They outline two main challenges: to face some resistance by the population: the risk of black-outs due to the difficult management of renewable intermittency, and a high level of expenses which are mainly paid by small consumers. The future of this policy may also been put into question again after the elections of September 2017

    Linkohr, R.

    2013-01-01

    Shortly after the Fukushima accident, the German chancellor, Angela Merkel, announced a new course for the country's energy policy: nuclear power is to be fully abandoned by 2022, owing to a massive recourse to renewable sources of energy. The proclaimed goal is for renewable energy to make up 35% of the country's energy mix by 2035 and even 80% by 2050. This energy transition, though benefiting from a consensus, has run up against several difficulties: an unadapted electric power grid, the excessively high costs of investment, and exorbitant electricity rates for consumers.... Till now, this energy policy's basis principles have not come under question, but questioning are arising about the pace and cost of this transformation. (author)

    The 2009 version of the German DRG system brought significant changes for urology concerning coding of diagnoses, medical procedures and the DRG structure. In view of the political situation and considerable economic pressure, a critical analysis of the 2009 German DRG system is warranted. Analysis of relevant diagnoses, medical procedures and G-DRGs in the versions 2008 and 2009 based on the publications of the German DRG-institute (InEK) and the German Institute of Medical Documentation and Information (DIMDI). The relevant diagnoses, medical procedures and German DRGs in the versions 2008 and 2009 were analysed based on the publications of the German DRG Institute (InEK) and the German Institute of Medical Documentation and Information (DIMDI). Changes for 2009 focus on the development of the DRG structure, DRG validation and codes for medical procedures to be used for very complex cases. The outcome of these changes for German hospitals may vary depending in the range of activities. The German DRG system again gained complexity. High demands are made on correct and complete coding of complex urology cases. The quality of case allocation in the German DRG system was improved. On the one hand some of the old problems (e.g. enterostomata) still persist, while on the other hand new problems evolved out of the attempt to improve the case allocation of highly complex and expensive cases. Time will tell whether the increase in highly specialized DRG with low case numbers will continue to endure and reach acceptable rates of annual fluctuations.

  7. German enterprises and the changes in energy economics due to increased concerns regarding environmental sustainability

    2015-06-01

    Full Text Available This article is part of a first year doctoral research regarding the current state of knowledge in environmental sustainability, energy economics and their impact on European enterprises. As the current changes and modifications of the German energy economics system are observed by people all around the globe, the current paper analyzes what has been said until now in the scientific literature on character of the new strategy for energy consumption and production in Germany and its impact on environmental and social sustainability. With the help of two questionnaire-based surveys conducted in 2013 and 2014 through the German DIHK1, German enterprises were surveyed in order to: identify potential differences and similarities between the two periods, identify the effects of the energy transition on companies’ profitability, and analyze these effects and compare the results in terms of potential trend developments. The research findings confirmed that changes in the energy system affect not only the environmental sustainability only, but also the economy, in some cases even independent of the stage in which the changing system of the economy presently is.

    This comprehensive final report for the Swiss Federal Office of Energy (SFOE) examines the efficiency of 'park and ride' (P+R) systems from the energy-efficiency point of view. 'Park and ride' means: 'Leave your car on a parking area and travel by public transport services for the second part of your journey'. Five hypotheses are examined: that P+R helps improve the general energy-efficiency of traffic, P+R installations are not an economically advantageous measure for improving the energy-efficiency of traffic, that they are not cost-effective, that they are financed by other public transport services and that their contribution to energy efficiency is dependent on the characteristics of their particular locations. The study looks at the positive and negative effects of P+R on energy efficiency and develops criteria for choosing locations. Three typical P+R installations are looked at - at a main station in a city centre, on the edge of a city and on a main city access road. These locations are analysed with respect to their energy and financial balances and their cost-effectiveness. Also, the use of P+R installations is analysed and the importance of the results of the study for traffic planning is discussed.

    This market survey for Germany is on the subject of renewable energy and energy efficient constructing and housing improvement. In order to meet sectoral or thematic information needs of Dutch exporting industries and investing companies, the EVD facilitates the realisation of up-to-date market surveys on promising markets in selected countries. The requested study is very relevant for the Dutch exporting industry, as the German building and construction market is of increasing importance to the Dutch building, installation and equipment building sector. Moreover the German market is a European innovator on renewable energy (RE) and energy efficient (EE) homes or even so-called 'passive' houses. The developments in the German market can guide the Dutch industry in the development of their export strategies. The main target groups for the market surveys are small- and medium-sized enterprises (SMEs) in the Netherlands. Interesting groups among these SMEs are those enterprises that start their business on a foreign market [nl

  12. Ideas on a competitive structure for German energy supplies

    Energy Technology Data Exchange (ETDEWEB)

    Bennigsen-Foerder, R v

    1985-12-20

    The author expresses the future need for action on the part of energy policy at Federal level in no uncertain terms. Regional experiments in energy policy and state-induced limits on competition in the heat market have documented the fact that watchfulness is to be recommended even in a relatively relaxed energy market. The author does admit that the level of electricity prices in the Federal Republic is comparatively high; overall, however, energy prices are in line with the world market situation. This can only be explained by deliberate renunciation of extensive state control of the primary energy structure. The competitiveness of German energy supplies can thus be closely linked up to the question as to what strategy will be pursued with regard to preparations for 'crisis contingency X', i.e. for another sudden explosion of energy costs. The author supports the thesis 'that it is more expensive from the point of view of the economy as a whole to prepare ex-ante for 'Day X' than it is to adapt to it ex-post'.

    2014-04-01

    Bilateral relations between Germany and Algeria are officially described, by both sides, as good and friendly. Nevertheless, in Germany, errors in assessment of the 'Arab spring' led to a lack of interest in Algeria, and still affect German foreign policy. Furthermore, the lack of reform in Algeria isolates the country both politically and economically, while it looks as if the evolution of the world energy market will be decisive for its development. The two countries have under-exploited, even totally neglected, the possibilities for cooperation on the energy market. Algeria may currently be one of the most stable countries in North Africa, but it will undergo some turmoil within the next fifteen years. This perspective should provoke a stronger response from the whole of Europe, and Germany in particular, leading it to engage more with the biggest African country, and still the richest one.

    The 11 th German Atomic Energy Law Symposium organized by the Federal Ministry for the Environment, Nature Conservation, and Nuclear Safety (BMU) was held in Berlin on October 9 and 10, 2001. Approximately 250 participants from industry, politics, administration, science, and associations had accepted the invitation by BMU and discussed a variety of questions arising mainly out of the new nuclear energy policy of the federal government. In the introductory session, Federal Minister for the Environment Juergen Trittin sketched the framework of federal policy resulting from the criteria set forth by the federal government and the negotiations with the power utilities after the agreement on the future use of nuclear power had been signed. The following seven technical sessions dealt with basic constitutional matters as well as problems of public law and economic law stemming from the nuclear power policy of the federal government. Major points included the amendment to the Atomic Energy Act, interim storage, the redefined objectives of final storage, and problems relating to yardsticks by which to gauge safety, and problems of ensuring safety. Among other subjects, also the relationship between the federal government and the federal states in nuclear regulatory matters as well aspects of power economy and energy policy were debated.

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

    The promotion of Blue Growth in aquaculture requires an understanding of the economic drivers influencing the sector at farm level, but the collection of reliable and comparable data at this level is time-consuming and expensive. This study suggests an alternative strategy for qualitative sampling...... of freshwater trout farms in Germany, Denmark and Turkey, using a combination of existing data, group discussions and interviews with trout farmers, consultants and researchers. Nine 'typical' trout farming models are described, focusing on profitability, productivity and energy efficiency and allowing in......-depth comparative economic analyses of different production systems at farm level, across regions. Our results show that the majority of the farms investigated have been profitable. Turkish farms benefit from competitive advantages due to low wages, low capital investment and favourable climate conditions. Large...

    On January 14, 2009, the German federal government introduced into parliament the 10th Act Amending the Atomic Energy Act. In the first reading in the federal parliament, Federal Minister for the Environment Gabriel emphasized 2 main points: Intensified protection of nuclear facilities and of transports of radioactive substances against unauthorized interventions; transfer by law to the Federal Office for Radiological Protection (BfS) of decommissioning of the Asse mine. Reliability review: The amendment to Sec.12 b of the Atomic Energy Act is to meet the different safety and security conditions after the terrorist attacks on September 11, 2001 in the United States and other terrorist activities afterwards (London, Madrid) also with respect to hazards arising to nuclear facilities and nuclear transports. The bill must be seen in conjunction with the Ordinance on Reliability Reviews under the Atomic Energy Act dated July 1, 1999 which covers reviews of reliability of persons holding special responsibilities. Asse II mine: The competence of the Federal Office for Radiological Protection is achieved by an amendment to Sec.23, Para.1, Number 2, Atomic Energy Act, in which the words ''and for the Asse II mine'' are added after the word ''waste.'' Further proceedings depend on the additional provision in a new Sec.57 b, Atomic Energy Act. Accordingly, the operation and decommissioning of the Asse II mine are subject to the regulations applicable to facilities of the federation pursuant to Sec.9a, Para.3. In this way, Asse II is given the same legal status as the federal waste management facilities. Moreover, it is stipulated that the mine is to be shut down immediately. (orig.)

  3. The market premium of the German Renewable Energy Sources Act 2012. Does it really contribute to both market and system integration of renewables?; Die Marktpraemie im EEG 2012. Ein sinnvoller Beitrag zur Markt- und Systemintegration erneuerbarer Energien?

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

  4. The German experience with grid-connected PV-systems

    Grid-connected photovoltaics experienced increasing attention in Germany in recent years and are expected to face a major boost at the beginning of the new millennium. Highlights like the German 100,000-Roofs-Solar-Programme, PV programmes at schools financed by utilities and governments (e.g. 'SONNEonline' by PreussenElektra, 'Sonne in der Schule' by BMWi and 'Sonne in der Schule' by Bayernwerk) and large centralised installations of MW size ('Neue Messe Munchen' by Bayernwerk and 'Energiepark Mont-Cenis' by state Nordrhein-Westfalen, Stadtwerke Herne and European Union) count for the potential of grid-connected PV. Today in Germany a typical grid-connected PV installation of 1 kW nominal power produces average annual energy yields of 700 kWh (dependent on location and system components) and shows a high operating availability. The price per kWh from PV installations is still significantly higher than the price for conventional energy, but new funding schemes and cost models (like the large increase of feed-in tariff in Germany due to the Act on Granting Priority to Renewable Energy Sources in 2000) give optimism about the future.

  5. Integration of renewable energies into the German power system and their influence on investments in new power plants. Integrated consideration of effects on power plant investment and operation

    2015-01-14

    The increasing share of renewable energies in the power sector influences the economic viability of investments in new conventional power plants. Many studies have investigated these issues by considering power plant operation or the long-term development of the power plant fleet. However, power plant decommissioning, investment and operation are intrinsically linked. This doctoral thesis therefore presents a modelling framework for an integrated consideration of power plant decommissioning, investment and operation. In a case study focusing on Germany, the effects of the integration of renewable energies on power plant decommissioning, investment and operation are evaluated in the context of different assumptions regarding the remaining lifetime of nuclear power plants. With regard to the use of nuclear power, a phase-out scenario and a scenario with lifetime extension of nuclear power plants (by on average 12 years) are considered. The results show that static decommissioning (i.e. considering fixed technical lifetimes) underestimates the capacity available in the power sector in the scenario without lifetime extension since retrofit measures (versus decommissioning) are not taken into account. In contrast, capacity available in the case of nuclear lifetime extension is overestimated since mothballing (versus regular operation) is not considered. If the impact on decommissioning decisions of profit margins accrued during power plant operation are considered (''dynamic decommissioning''), the electricity price reduction effect due to a lifetime extension is reduced by more than half in comparison to static decommissioning. Scarcity situations do not differ significantly between the scenarios with and without lifetime extension with dynamic decommissioning; in contrast, there is a significantly higher need for imports without lifetime extension with static decommissioning. The case study demonstrates that further system flexibility is needed for

    The German DRG (diagnosis-related groups) system has been modified and updated into version 2008. For orthopedic and trauma surgery significant changes concerning coding of diagnoses, medical procedures and the DRG structure were made. The modified version has been analyzed in order to ascertain whether the DRG system is suitably qualified to fulfill the demands of the reimbursement system or whether further improvements are necessary. Analysis of the severity of relevant side-effect diagnoses, medical procedures and G-DRGs in the versions 2007 and 2008 was carried out based on the publications of the German DRG institute (InEK) and the German Institute of Medical Documentation and Information (DIMDI). Changes for 2008 focused on the development of DRG structure, DRG validation and codes for medical procedures. The outcome of these changes for German hospitals may vary depending on the range of activities. G-DRG system has become even more complex and the new regulations have also resulted in new problems associated with complications.. High demands are made on correct and complete coding of complex orthopedic and trauma surgery cases. Quality of case allocation within the G-DRG system has been improved. Nevertheless, further improvements of the G-DRG system are necessary, especially for cases with severe injuries.

    In this article we demonstrate how challenging greenhouse gas reduction targets of up to 95% until 2050 can be achieved in the German electricity sector. In the analysis, we focus on the main requirements to reach such challenging targets. To account for interdependencies between the electricity market and the rest of the economy, different models were used to account for feedback loops with all other sectors. We include scenarios with different runtimes and retrofit costs for existing nuclear plants to determine the effects of a prolongation of nuclear power plants in Germany. Key findings for the electricity sector include the importance of a European-wide coordinated electricity grid extension and the exploitation of regional comparative cost effects for renewable sites. Due to political restrictions, nuclear energy will not be available in Germany in 2050. However, the nuclear life time extension has a positive impact on end consumer electricity prices as well as economic growth in the medium term, if retrofit costs do not exceed certain limits.

    Bizet, Jean

    2014-01-01

    As the French-German energy cooperation has been, until now, focused on the transition towards renewable energies, this report studies this issue of energy transition by distinguishing the purely technical dimension and the macro-economic aspect. The author first identifies the various reasons of the difficulties met by energy transition (they are essentially based on the intermittency). In order to be efficient, the cooperation must therefore comprise a portion dealing with the economic management of the energy system in order to protect markets from abnormal disturbances. As far as the technical dimension is concerned, the author discusses the multitude of still immature techniques to deal with intermittency and hazard, or with energy savings or recovery. He also addresses the technical diptych constituted by storage and grid (energy storage and smart grids are two different but related techniques). In the second part, the author addresses the economic dimension. He highlights the unsustainable cost of a transition made at a forced march, and discusses the relationship between price regulation, market management, and transition rate. Here, he outlines that nuclear energy remains indispensable to transition. Appendices present the main recent steps of the French-German energy cooperation, a comparison of the energy mix of these both countries, the German energy policy, and a discussion of a targeted energy mix

    Misconceptions and biases in energy perception could influence people's support for developments integral to the success of restructuring a nation's energy system. Science education, in equipping young adults with the cognitive skills and knowledge necessary to navigate in the confusing energy environment, could play a key role in paving the way for informed decision-making. This study examined German students' knowledge of the contribution of diverse energy sources to their nation's energy mix as well as their affective energy responses so as to identify implications for science education. Specifically, the study investigated whether and to what extent students hold mistaken beliefs about the role of multiple energy sources in their nation's energy mix, and assessed how misconceptions could act as self-generated reference points to underpin support/resistance of proposed developments. An in-depth analysis of spontaneous affective associations with five key energy sources also enabled the identification of underlying concerns driving people's energy responses and facilitated an examination of how affective perception, in acting as a heuristic, could lead to biases in energy judgment and decision-making. Finally, subgroup analysis differentiated by education and gender supported insights into a 'two culture' effect on energy perception and the challenge it poses to science education.

    The author first presents and discusses the new German legal framework which has been introduced in July 2011 and defined a new energy policy. This policy notably decides to shut down some nuclear reactors and to phase out nuclear by 2022, with a massive use of renewable energies and a decrease of energy consumption. The author discusses the consequences of this important change on the European electric system for the years to come. He also discusses the impact of these decisions on the European energy policy in terms of electricity market and price, greenhouse gas emissions and CO 2 price. He finally examines perspectives for Germany in terms of economic risks and possible industrial breakthrough

    Schiffer, Hans-Wilhelm; RWTH Aachen Univ.; World Energy Council, London

    2014-01-01

    The present book provides an overview of the energy market of the German Federal Republic. Its main emphasis is on structures of demand and supply in the markets for crude oil, brown coal, hard coal, natural gas and electricity. A special chapter has been dedicated to renewable energy resources. Another focal area are the price formation mechanisms for oil, coal, natural gas and electricity. The development of energy demand is analysed, differentiating between the sectors industry, transport, households and trade/industry/services. The book addresses the international climate protection treaties, the legal framework for climate protection activities at the European level and the implementation of trade in greenhouse gas emission permits in Germany. It presents current forecasts and scenarios, thus pointing out possible perspectives in the German energy market. It also discusses the framework conditions for Germany's energy policy. The energy markets are portrayed through facts and figures compiled in a total of 125 tables and 148 diagrams. Details of ownership of more than 100 utility companies are made transparent. The chapter on energy in the coalition agreement of 27 November 2013 between the Christian Democratic Union, Christian Social Union and the Social Democratic Party is documented verbatim. Rounding off the publication is a detailed glossary that will facilitate the reader's understanding of complex matters in the field of energy economy.

    The German Diagnosis-Related Groups (DRG) System was further developed into its 2007 version. For orthopedic and trauma surgery, significant changes were made in terms of the coding of diagnoses and medical procedures, as well as in the DRG structure itself. The German Societies for Trauma Surgery and for Orthopedics and Orthopedic Surgery (Deutsch Gesellschaft für Unfallchirurgie, DGU; and Deutsche Gesellschaft für Orthopädie und Orthopädische Chirurgie, DGOOC) once again cooperated constructively with the German DRG Institute InEK. Among other innovations, new International Classification of Diseases (ICD) codes for second-degree burns were implemented. Procedure codes for joint operations, endoprosthetic-surgery and spine surgery were restructured. Furthermore, a specific code for septic surgery was introduced in 2007. In addition, the DRG structure was improved. Case allocation of patients with more than one significant operation was established. Further DRG subdivisions were established according to the patients age and the Patient Clinical Complexity Level (PCCL). DRG developments for 2007 have improved appropriate case allocation, but once again increased the system's complexity. Clinicians need an ever growing amount of specific coding know-how. Still, further adjustments to the German DRG system are required to allow for a correct allocation of cases and funds.

    The overall good performance of the West German energy industry in terms of energy policy objectives such as security of supplies, competitiveness, efficient use of energy and environmental protection, is attributable to an energy policy based on the principles of the market economy and steady application of these same principles. Today, though, a debate, at times controversial, on whether more market influence or more government intervention is required is underway in West Germany; in view of the successes of energy policy and the balance struck between free enterprise and the government in the past, this debate has met with little understanding in some quarters. It is generally agreed, though, that the quality of the challenges energy policy and the energy industry in West Germany will confront in the future will remain essentially unchanged. West German energy policy will have to deal with: reestablishing a consensus on coal and nuclear power policy; achieving a high standard of environmental protection in the European Communities, and strengthening the position of the energy industry as efforts are made to get moves underway to create a single European market for energy underway. No fundamental change in the course of energy policy in the Federal Republic of Germany is needed to solve current energy policy issues or to preserve the underlying goals of this policy. An energy policy which continues to give priority where possible to market mechanisms as a means of adjustment and provides energy suppliers and users with a stable and reliable framework in which to operate, offers the best promise for meeting the challenges of the future.

  3. Business model innovation for sustainable energy: German utilities and renewable energy

    International Nuclear Information System (INIS)

    Richter, Mario

    2013-01-01

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

    The German energy turnaround is at the heart of its climate and energy policy, but also determines Germany's attitude in international negotiations. Apart from the necessary revision of the Renewable Energy Act, the new coalition that took power in December 2013 will probably continue the previous climate and energy policy. The main changes are of a structural nature, and relate to a new distribution of competences between the Economy and Environment Ministries, which are, furthermore, for the first time headed by members of the same political party. At the EU level, Berlin could recover, thanks to a unified approach, its ability to influence climate and energy policies, and thus facilitate an agreement on the 2030 climate and energy package. Besides, for its own interests, Germany needs Europe to have high ambitions in so far as its national goals would be less difficult and costly to attain if they form part of an overall European approach. The personal engagement of the chancellor would certainly be an important variable in the negotiations, since Germany will chair the G7 in 2015. Similarly, in view of France hosting the United Nations climate summit (COP 21) in Paris in the same year, enhanced Franco-German cooperation would be in the interest of both countries and generate a strong political dynamic.

    Since 1999, the German photovoltaic market has been growing rapidly. In 2003, more than 130 MWp PV systems were installed in Germany; in 2004, more than 200 MWp are expected to be installed additionally. The main reason for this impressive market success has been the market stimulation policy of the German government. In January 1999, the 100.000 Roofs Programme for photovoltaic systems had started, offering interest-reduced loans for PV systems. In April 2000, it was backed by the Renewable Energy Sources Act (EEG), which considerably increased the feed-in tariff to 99 Pfennig (0.51 euros) per kWh. Since then, the PV market has boomed. In 2003, the 100,000 Roofs Programme (HTRP) ended successfully, after loans for more than 300 MWp PV systems had been granted. In order to fill the gap created by the termination of the programme, the government decided to increase the feed-in tariff provided by the EEG. Since January 2004, grid-connected PV systems on roofs and facades receive a tariff between 0,540 euros and 0,624 euros per kWh over 20 years. This improvement of the EEG further increased the interest in photovoltaics. The growth rate of the photovoltaic market, exceeding 50% in 2004, has led to the demand being higher than the available supply of PV systems. (author)

    Both France and Germany have ratified the Paris Agreement on Climate Change and are pursuing broad, long-term strategies to deeply decarbonize their economies by 2050. (France aims to reduce GHG emissions by 75% and Germany by 80 to 95% relative to their 1990 levels.) This strong political commitment to fighting climate change is deeply rooted in values and beliefs of German and French citizens and enjoys broad public support in both countries. The French Transition Energetique and the German Energiewende form the backbones of their respective decarbonization strategies. Both envisage step-by-step changes in the energy system, encompassing the power, transport and heating and cooling sectors

    Not at least because of 'Fukushima accident', Emergency power supply (EPS) systems with diesel engines are regarded as higher safety-important as 20 years ago. This presentation shows the design and approval of the emergency power facilities of the German nuclear power plants. It deals with the essential details e. g.: EPS Diesel integration to main power grid of the German BWR and PWR; Procedure for 'Loss of off-site power (LOOP)-Design'; Design robustness of AC Power Supply (Design requirements: independent redundancies, airplane crash, explosion pressure wave, earth-quake); Cooling systems (chilled by river water, air, well water, stored water volume); Layout of the stationary emergency Diesel generator (fuel supply, starting system); Layout of the bunkered EDG with directly driven emergency feed water pump; Robustness of AC power supply beyond design; Layout of mobile chilling equipment for diesel engines; Layout of mobile Diesel gen-sets (200 kVA and 1250 kVA); German Requirements of KTA 3702 versus US-IEE 323; Construction, Materials and Testing of EDG; Maintenance (in-service inspections, operation, Repair); Lessons learned (e. g. crank house cracks, start failure due to too much oil in the combustion chamber) (author)

  11. The German quality system for waste repositories

    1993-01-01

    The Bundesamt fuer Strahlenschutz (BfS)--Federal Office for Radiation protection--has to guarantee that the requirements resulting from different regulations concerning planning, design, construction, operation and decommissioning of a waste repository are fulfilled. In addition, the results of the safety assessments lead to nuclear-specific requirements on the design of the plant as well as to requirements on the radioactive waste packages intended to be disposed of. Therefore, the implementation of a quality assurance (QA) and quality control (QC) system is an essential task in order to ensure that the designed quality is achieved so that the necessary precaution against damage is taken. In this paper, a detailed description of QA and QC to be applied to the planned Konrad repository as well as the basic principles and the present status of the waste package QC are indicated and discussed

  12. Smart border initiative: a Franco-German cross-border energy optimisation project

    Integrated and optimised local energy systems will play a key role in achieving the energy transition objectives set by France and Germany, in line with the Energy Union's goals, and contribute to ensuring a secure, affordable and climate-friendly energy supply in the EU. In order to capitalise on the French and German expertise and experiences in developing such systems and to continue strengthening the cross-border cooperation towards a fully integrated European energy market, both Governments have decided to launch a common initiative to identify and structure a cross-border energy optimisation project. Tilia and Dena have undertaken this mission to jointly develop the Smart Border Initiative (SBI). The SBI will, on the one hand, connect policies designed by France and Germany in order to support their cities and territories in their energy transition strategies and European market integration. It is currently a paradox that, though more balanced and resilient energy systems build up, bottom-up, at the local level, borders remain an obstacle to this local integration, in spite of the numerous complementarities observed in cross-border regions, and of their specific needs, in terms of smart mobility for example. The SBI project aims at enabling European neighbouring regions separated by a border to jointly build up optimised local energy systems, and jointly develop their local economies following an integrated, sustainable and low-carbon model. On the other hand, this showcase project will initiate a new stage in the EU electricity market integration, by completing high voltage interconnections with local, low voltage integration at DSO level, opening new optimisation possibilities in managing the electricity balance, and enabling DSOs to jointly overcome some of the current challenges, notably the increased share of renewable energy (RE) and ensuring Europe's security of supply

    LEPC, the Large Electron Positron Collider being built at CERN, will be ready for experiments in 1988. A large array of bismuth germanate crystals will be part of one of the first experiments to be installed. Particles (including photons) resulting from the collisions will be identified and measured in the surrounding detector. At the center of this composite detector is a tracking device to observe the trajectories of all particles. Beyond this is the bismuth germanate array; it will measure the energy of electrons and photons from a few MeV to 100 GeV. This is surrounded by the hadron calorimeter. The bismuth germanate calorimeter will consist of about 12,000 individual bismuth germanate crystals. Each crystal will have an independent readout system. This system uses silicon photodiodes, each with its own ADC, to measure the scintillation light from each crystal. The ADC is implemented in software in a single chip microcomputer, using a modification of successive approximation, which produces a very wide dynamic range. The microcomputer also provides data buffering and several other housekeeping functions. The initial design of the readout system, presented in this paper, evolved from an attempt to minimize the size requirements and the number of cables needed, and to meet the dynamic range requirement in a practical way.

  17. Distributional Challenges of Sustainability Policies—The Case of the German Energy Transition

    Erik Gawel

    2015-12-01

    Full Text Available Sustainability policies based on the economic rationale of providing incentives to get prices right inevitably place a significant burden on society and often raise distributional concerns. The social acceptability of Germany’s energy transition towards more sustainable generation and usage of energy is frequently the subject of such critical appraisals. The discourse centres upon the burden imposed on electricity users as a result of the promotion of renewable energy sources in the electricity sector in accordance with the German Renewable Energy Sources Act (EEG. A regressive EEG surcharge is suspected of driving up energy prices unreasonably and of being socially unjust. It is also argued that high-income utility owners profit from the EEG system at the expense of low-income electricity consumers (redistribution from bottom to top. The aim of this paper is to examine the validity of these two hypotheses and to show that both exhibit substantial theoretical and empirical weaknesses, with climate and environmental policy being played off against social policy in a questionable manner. At the same time, the article points out remaining conflicts between energy policy and social policy and makes corresponding policy recommendations for their resolution, thus contributing to reconciling distributional concerns arising in the context of incentive-oriented sustainability governance.

    Although the Brussels Nuclear Ship Liability Convention of 1962, whose incorporation into German law was agreed upon by the German Federal Parliament (the Bundestag) in 1975, will have only minor international significance once it has entered into force, it will yet provide a new legal basis for the nuclear liability of the German vessel N.S. 'Otto Hahn' for the periods of her stay within the Federal Republic of Germany. However, there is no smooth concurrence of the Brussels Convention and the German Atomic Energy Act adapted to the Paris Liability Convention in 1975. This means that a number of questions still need to be resolved with respect to the protection of victims and the liability of shipowners. (orig.) [de

    1977-01-01

    The essay deals with utilizable regenerative energy sources: geothermal energy, tidal energy, solar energy, running water energy, and wind energy. Tests for the development of these sources have been carried out, but only one of them has a considerable share in meeting the energy demand--that gained from running water. The others are only of regional importance (geothermal energy, tidal energy) or have lost the importance they once had (wind energy, biochemical energy in the form of wood). The latest discussions about the restrictions on fossil and nuclear energy sources and the environmental effects of the technologies necessary for their utilization have increased the interest in the ''inexhaustible'' energy sources. This is why the author outlines the possible importance of renewable energy sources.

  1. Energy production from grassland - Assessing the sustainability of different process chains under German conditions

    In many regions of Europe, grassland shapes the landscape and fulfils important functions in protecting nature, soil, and water. However, the traditional uses of grassland for forage production are vanishing with progress in breeding and structural adaptations in agriculture. On the other hand, the demand for biomass energy is rising due to political sustainability goals and financial measures to support renewable energy. Against this background, the Institute for Technology Assessment and Systems Analysis investigated the applicability, economic efficiency, and sustainability of different techniques for energy production from grassland as well as from grassland converted into maize fields or short-rotation poplars under German conditions. The results show that despite relatively high energy prices and the financial support for bioenergy, the effects of energy production from grassland on employment in agriculture and farmers' income are modest. What is beneficial are savings in non-renewable energy, reductions in greenhouse gas emissions, and local provision of energy carriers. If grassland biomass (grass silage or hay) is used for energy purposes, this brings the further advantages of preserving biodiversity and the cultural landscape and protecting of soil and groundwater. Negative impacts on sustainable development result from an increase in emissions, which leads to acidification, eutrophication, and risks to human health. The overall evaluation indicates that short-rotation poplars are comparatively advantageous from the economic and ecological point of view. Therefore, a development plan for grassland is required to identify areas where grassland could be used as an energy resource or where it would be favourable to install energy plantations with fast-growing perennial plants

    In 2008, a program was established in Germany to provide grants for energy audits in small- and medium-sized enterprises. It aims to overcome barriers to energy efficiency, like the lack of information or a lack of capacity, and is intended to increase the adoption of energy efficiency measures. We evaluate the program's impact in terms of energy savings, CO2 mitigation, and cost-effectiveness. We find that firms adopt 1.7-2.9 energy efficiency measures, which they would not have adopted without the program. Taking a firm's perspective, the program shows a net present value ranging from -0.4 to 6 euro/MWh saved, which very likely implies a net benefit. For the government, each ton of CO2 mitigated costs between 1.8 and 4.1 euro. Each euro of public expenditure on audit grants led to 17-33 euro of private investment. The cost-effectiveness of the program for firms and the low share of public expenditure underline its value for the German energy efficiency policy mix and suggest that it should be expanded in Germany. Further, the good experiences with the program in Germany should encourage countries which have not yet established an audit program to do so.

    Analyzing the chemical industry’s energy use is challenging because of the sector’s complexity and the prevailing uncertainty in energy use and production data. We develop an advanced bottom-up model (PIE-Plus) which encompasses the energy use of the 139 most important chemical processes. We apply this model in a case study to analyze the German basic chemical industry’s energy use and energy efficiency improvements in the period between 1995 and 2008. We compare our results with data from the German Energy Balances and with data published by the International Energy Agency (IEA). We find that our model covers 88% of the basic chemical industry’s total final energy use (including non-energy use) as reported in the German Energy Balances. The observed energy efficiency improvements range between 2.2 and 3.5% per year, i.e., they are on the higher side of the values typically reported in literature. Our results point to uncertainties in the basic chemical industry’s final energy use as reported in the energy statistics and the specific energy consumption values. More efforts are required to improve the quality of the national and international energy statistics to make them useable for reliable monitoring of energy efficiency improvements of the chemical industry. -- Highlights: ► An advanced model was developed to estimate German chemical industry’s energy use. ► For the base year (2000), model covers 88% of the sector’s total final energy use. ► Sector’s energy efficiency improved between 2.2 and 3.5%/yr between 1995 and 2008. ► Improved energy statistics are required for accurate monitoring of improvements.

  4. Constitutional compatibility of energy systems

    1983-01-01

    The paper starts from the results of the Enquiry Commission on 'Future Nuclear Energy Policy' of the 8th Federal German Parliament outlining technically feasible energy futures in four 'pathways'. For the purpose of the project, which was to establish the comparative advantages and disadvantages of different energy systems, these four scenarios were reduced to two alternatives: cases K (= nuclear energy) and S (= solar energy). The question to Ge put is: Which changes within our legal system will be ushered in by certain technological developments and how do these changes relate to the legal condition intended so far. Proceeding in this manner will not lead to the result of a nuclear energy system or a solar energy system being in conformity or in contradiction with the constitutional law, but will provide a catalogue of implications orientated to the aims of legal standards: a person deciding in favour of a nuclear energy system or a solar energy system supports this or that development of constitutional policy, and a person purishing this or that aim of legal policy should be consistent and decide in favour of this or that energy system. The investigation of constitutional compatibility leads to the question what effects different energy systems will have on the forms of political intercourse laid down in the constitutional law, which are orientated to models of a liberal constitutional tradition of citizens.

    1988-01-01

    The book investigates the question whether the peaceful use of nuclear energy is a technology accepted and mastered by society in the G.D.R., i.e. in a system of real socialism. The author first reviews the history of nuclear technology and its changing role from a source of hope and trust in progress to a fill-in. Then the question is discussed whether the combination of nuclear technology and socialism has proven the world to be a successful symbiosis. It is shown that discussions about the advantages or disadvantages of nuclear technology, actually a means of forming public opinion, are kept behind closed doors and are by no means intended to include participation of the public. The author concludes that nuclear technology is not controlled by society. Its development was determined by feasibility speculations, economic pretentions, and vague prognostics rather than by sound projecting and planning on the basis of technical, economic and energy policy principles. Real socialism, too, puts an unmeasurable risk on society by supporting nuclear technology. Public opinion making by no means allows controversial discussions about assessment of nuclear technology, its value, or the acceptable risk associated with it. (orig./HSCH) [de

  8. Interactions between the German Electricity Spot Market and the Reserve Energy Market

    International Nuclear Information System (INIS)

    Graeber, Bernhardt

    2005-01-01

    Eight years after market opening, Germany has well established spot and future markets for electricity. Besides OTC and Internet broker platforms the main market place is the European Energy Exchange in Leipzig (EEX) with its spot and future market. Less known is the reserve energy market in Germany. The four German transmission system operators (TSOs) EnBW, EON, RWE and Vattenfall purchase network services on the reserve energy market. Products with specific technical requirements are primary, secondary and tertiary reserve. (Details about the technical requirements and typical means for providing the required services will be presented.) Each TSO organises a separate auction for these products - for primary and secondary reserve half-yearly, for tertiary reserve daily. Due to the technical requirements the liquidity on these markets is limited, but especially on the tertiary reserve market it is recently growing significantly due to new participants marketing several smaller municipal and industrial reserve power plants as combined bids which meet the 30 MW min. capacity requirement. Every power plant or interruptible load could not only be offered as capacity on the reserve market but could also be dispatched for the spot market. Therefore the developments of prices on these markets are not independent and opportunity costs against the spot market can be estimated for different type of plants bidding in the reserve market. Another interaction between reserve and spot market is caused by the balancing price system in Germany. Prices for balancing energy meeting deviations between load, trading balance and production of a market participant are based on quarter-hourly reserve energy costs encountered by the TSO. As unbiased load and production forecasts are not strictly enforced by the TSOs so far, part of the planned demand could be met with balancing energy if EEX spot market prices rise above expected balancing energy prices. This interrelationship has a

    2011-01-01

    The housing sector is a major consumer of energy. Studies on the future energy demand under climate change which also take into account future changes of the building stock, renovation measures and heating systems are still lacking. We provide the first analysis of the combined effect of these four influencing factors on the future energy demand for room conditioning of residential buildings and resulting greenhouse gas (GHG) emissions in Germany until 2060. We show that the heating energy demand will decrease substantially in the future. This shift will mainly depend on the number of renovated buildings and climate change scenarios and only slightly on demographic changes. The future cooling energy demand will remain low in the future unless the amount of air conditioners strongly increases. As a strong change in the German energy mix is not expected, the future GHG emissions caused by heating will mainly depend on the energy demand for future heating. - Highlights: → The future heating energy demand of German residential buildings strongly decreases. → Extent of these changes mainly depends on the number of renovated buildings. → Demographic changes will only play a minor role. → Cooling energy demand will remain low in future but with large insecurities. → Germany's 2050 emission targets for the building stock are ambitious.

    In German, the coalition political power of SPD and Gruene decided the present nuclear policy on 20th October 1998. It consisted of three steps: the first step is amendment of the present Atomic Energy Law, the second step the consensus conference with the power industry for one year and the third step is enactment of law to decrease nuclear power with compensation. The first consensus conference opened 26th January 1999. The content was that the stop of reprocessing did not decide the limit and the atomic power plants were operated until obtaining consensus. Then, Muller Secretary of Commerce and the power industry carried out unofficial meeting and decided the following: limit of operating atomic power plants is 35 years (until 2024), reprocessing can be done until 2004 and the undertakers do not request compensation to the governmental agencies. However the environmental secretary and Gruene objected to them. 570 of German scientists and technologists published memorandum for discussing the present conditions of German and the earth. England and France opposite limit of reprocessing spent fuel. A joint concern between Siemens (German) and Framatome (France) is going to establish. The point under discussion about present power policy is selection of energy. There are many problems in German. (S.Y.)

  13. Unruly energies: Provocations of renewable energy development in a northern German village

    Science.gov (United States)

    Carlson, Jennifer D.

    This dissertation asks how inhabitants of a sustainable village are living out Germany's transition from nuclear to renewable energy. The sustainable village remains a locus of optimistic attachments for renewable energy advocates, who argue that a decentralized power grid will enable people to more directly participate in power production and politics as "energy citizens." Yet while rural areas have become sites of speculation, innovation and growth, few rural-dwellers are enfranchised in (or profiting from) the technoscientific projects in their midst. I draw upon 13 months of fieldwork in a northern German village transformed by wind turbines, photovoltaics and biofuels to consider why, asking what kinds of public life flourish in the absence of democratic engagement with renewable technologies. This ethnography engages the village as multiply constituted across domains of everyday life, including transit, farming, waste management, domestic life, and social gatherings. I found that environmental policy, everyday practices, and the area's material histories combined to produce ontologies---senses of what exists---that circumscribe citizen participation in the energy sector, affording more formal opportunities to men than to women, and privileging farmers' interests in plans that impacted the larger community. These findings illuminate how many villagers become ambivalent toward the project of the energy transition and disenfranchised from its implementation. Yet many who were excluded from formal participation also engaged with renewable technologies as they sensed out their worlds, using tropes of sustainable energy and technoscientific materials to place themselves in this emerging energy polity. Their everyday worldmaking brimmed with what I call unruly energies, structures of feeling that registered more as affects than as discourse. In the village, these took form as sensory disturbances, disquiet among neighbors, technoscientific optimism and skepticism

    In 1998 the German electricity market became fully liberalised for competition. Prices for all consumer groups recorded a considerable drop. Service centres accepted measures for cost reduction, new strategies resulted in mergers. However, in view of economic efficiency, the German Government set life surroundings as the primary task. With new electricity market regulation numerous grants were introduced into renewable energy sources as well as the combined production of heat and electricity, which had a destabilising effect on all price savings on the part of the competition.(author)

  16. Atomic energy law after the opt-out. Alive and fascinating. Report about the 14th German atomic energy law symposium 2012

    Atomic energy law remains a living, fascinating subject matter. Nearly 200 participants were convinced of this impression at the 14 th German Atomic Energy Law Symposium held in Berlin on November 19-20, 2012. Under the scientific chairmanship of Professor Dr. Martin Burgi, Ludwig Maximilian University of Munich, the German Federal Ministry for the Environment, Nature Conservation and Nuclear Safety (BMU), after an interruption of 5 years, again organized a scientific conference about practice-related topics of atomic energy and radiation protection law. Atomic energy law once again proved to be a reference area for sophisticated issues of constitutional law and administrative law above and beyond its technical confines. The agenda of the 14 th German Atomic Energy Law Symposium featured a broad spectrum of topics ranging from backfitting of nuclear power plants to European atomic energy and radiation protection law, to challenges facing national legal systems in the execution of atomic energy law, to legal issues connected with decommissioning and waste management, and on to the topical subject of finding a repository site. The 14 th German Atomic Energy Law Symposium, on the whole, again demonstrated that an open discourse between science and practice is able to furnish important contributions to the implementation of laws in a balanced way rooted in practice. Especially the contributions dealing with the independence of public authorities and their organization, the doctrine of the reservation of functions of the executive branch, and planning by laws contain additional provisions able to influence the continued development of administrative law also above and beyond atomic energy law. The BMU also referred to a decision just heard from Brussels to the effect that a new European Safety Directive would be published as early as in 2013. As a consequence of the nuclear stress tests conducted EU-wide, the Directive is to lay down provisions about transparency

    The portfolio of the BMFT (Federal Ministry of Research and Technology) covers under the competence of the Federal Government all activities in the field of nuclear science and engineering for peaceful uses of nuclear energy, reactor safety research, and research on non-nuclear energy sources and technology. The draft budget for 1989 shows a total expenditure of DM 7.65 billions in the section 30, portfolio of the BMFT. This is about 1.2% more than in the draft budget of 1988. Broken down into programmes, DM 1.853 billions are earmarked for energy research and technology (1988: DM 1.854 billions), of these DM 398.5 millions for the promotion of non-nuclear energy research and technology.

    2015-01-01

    As France and Germany are both defining new energy policies, but in different ways (Germany has focused on a reform of the law on renewable energies, and France aims at a reduction of the nuclear share from 75 to 50 per cent by 2025), the author examines whether the French strategy is realistic and how it can be explained from a political point of view, how energy transition can be successfully implemented, and to what extent it may influence the German policy within the framework of present discussions on the EU energy-climate package and of bilateral cooperation. The author first outlines the powerful role of nuclear energy in the history of French energy policy, proposes a brief overview of the evolution of debates in France on energy policy from the beginning of the 2000's, indicates and discusses the main objectives of the present bill project on energy transition, and proposes a comparison of French and German objectives regarding energy transition by 2020, 2030 and 2050. He evokes some practical aspects (discussion about Fessenheim plant shutting down, issues of energy prices). He comments the planned implementation of a new economic model based on a green growth, discusses the issue of energy transition in the electricity sector and in the transport sector, and the relationship between energy transition and decentralisation. Perspectives are briefly discussed regarding the credibility of the French policy and the commitment of both countries in energy transition

    If, to lay the foundations of the European Community of Steel and Coal (ECSC), the founding fathers of Europe had waited for the steelworks belonging to the Krupp family and the Creusot foundries to decide of their own accord to work closer together, the European Union would simply not have been created. Even today an ambitious European energy strategy cannot materialise unless it is supported by France and Germany. A political agreement is indeed necessary given the complexity of the market and the interplay of both public and private factors. Energy strategies in France and Germany have remained far too national, sometimes going as far as to diverge, which makes no sense in the context of European integration. The resulting incoherence has prevented the pooling of industrial investments at the very moment European energy markets are increasingly integrated and European industrialists are at risk of being outrun, both technologically and commercially, by their foreign competitors. On the occasion of the 50. anniversary of the Elysee Treaty France and Germany have tried to renew energy cooperation admitting that they face similar challenges in terms of energy transition and that they would have everything to gain by working together to rise to those challenges. Ideas were put forward which should be clarified, completed and made into a reality. Indeed there is a rare opportunity for a vast bilateral cooperation project consistent with the two countries' responsibility towards Europe. The objection over the disparity of energy choices between France and Germany, in terms of electricity production could be solved if we acknowledge that the markets and issues associated with energy transition extend beyond our national borders. Basically this means having quite an ambitious political vision of the constructive, coherent governance of energy transition. (authors)

    Having crossed the threshold into the new millennium the power utilities business finds itself confronted by new challenges. In worldwide terms the uppermost objective is, while taking due account of climatic factors and of the obligations resulting from the various World Climate Conferences held so far, to ensure a sufficient and reliable supply of energy for the world's growing population. The gap between the supply of energy and the demand for energy must be closed. In European terms the situation looks a little different. The supply structure is excellent - characterized more by over-capacity than energy shortage. As a result of the liberalization process that has started, the European power utilities have undergone vital changes. Market influences on the power utilities corporations are massive. Fusions and takeovers are the order of the day. The German power business, like others in Europe, is feeling the effects of these two aspects. Also, at national level in Germany, there is the attempt to reach a new energy consensus. An agreement was reached on the 14. of June 2000 between the German federal government and the power utilities. This laid down regulations on the future operation of German nuclear power plants and the disposal of spent fuel elements - to apply up until the government's planned withdrawal from nuclear power. However, the politicians have yet to answer the question of how, in the long term, a sensibly balanced German energy mix might look. There is not as yet - nor in the foreseeable future is there likely to be - an energy consensus in Germany supported by all social and political groups. The respective approaches and ideas differ too widely. The failure, in the so-called 'Energy dialog 2000', of political parties, environmental organizations, and representatives from industry to achieve any results that might point the way forward and tell us where we are heading shows this all too clearly.

    1979-02-01

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

  5. Institutional change in European natural gas markets and implications for energy security: Lessons from the German case

    International Nuclear Information System (INIS)

    Westphal, Kirsten

    2014-01-01

    This article focuses on institutional change in the German gas market driven by EU internal market and climate policies. It argues that institutional change has functional externalities for energy security. The German gas market provides a useful case study, as Germany is the biggest continental gas market, a major hub and transport country which has largely privatised, unbundled and separated its natural gas undertakings. Transition is ongoing, tending towards an internal market. Inter/national natural gas economics is in flux. Institutional evolution has repercussions for corporate and market structures, the operating of the system and the realization of transactions. Changes in the institutional framework crucially affect energy security, which is often associated with institutional stability. On the basis of this case study, it is argued herein that the security of natural gas supplies should be reexamined in the context of the developments described above, since overall the institutional changes in natural gas security lag behind the EU’s internal natural gas market development. - Highlights: • EU natural gas market regulation primarily aims to establish competitive markets. • German/EU regulatory approach has externalities for supply security. • Institutional changes and breaks with path dependencies take place in Germany/the EU. • Institutional change results in increasing uncertainty and complexity. • Subsequent change in perceptions and expectations may destabilise trade relations

    2009-01-01

    The German Renewable Energy Act (EEG) has been very successful in promoting the deployment of renewable electricity technologies in Germany. The increasing share of EEG power in the generation portfolio, increasing amounts of fluctuating power generation, and the growing European integration of power markets governed by competition calls for a re-design of the EEG. In particular, a more efficient system integration and commercial integration of the EEG power is needed to, e.g. better matching feed-in to demand and avoiding stress on electricity grids. This article describes three different options to improve the EEG by providing appropriate incentives and more flexibility to the promotion mechanism and the quantitative compensation scheme without jeopardising the fast deployment of renewable energy technologies. In the 'Retailer Model', it becomes the responsibility of the end-use retailers to adapt the EEG power to the actual demand of their respective customers. The 'Market Mediator Model' establishes an independent market mediator responsible to market the renewable electricity. This model is the primary choice when new market entrants are regarded as crucial for the better integration of renewable energy and enhanced competition. The 'Optional Bonus Model' relies more on functioning markets since power plant operators can alternatively choose to market the generated electricity themselves with a premium on top of the market price instead of a fixed price

    Kuhnt, D. [RWE Energie AG, Essen (Germany)

    2000-07-01

    The author argues in favor of a more fact-oriented German energy policy: Firstly, German energy policy must accept the new European framework of a market economy. This means that German utilities must no longer be burdened with the implementation of political objectives. The German power industry needs a level playing field for competition on a European scale. Consequently, also the European partner countries should not limit themselves to the minimum conditions of the Single Market Directive in opening their markets. Secondly, German energy policy must develop new forms of cooperation with the power industry so as to maintain domestic employment and the addition of value despite considerably stronger competitive pressure. Also the conflicting targets of sustainability, continuity of supply, and economic viability must not only be discussed, but must be turned into productive approaches. Thirdly, this means that there must be no inadmissible solution in matters nuclear. If the German power industry is to remain strong, in the interest of domestic jobs and opportunities for the future, it must not lose any more domestic market share to other European companies. Fourthly, we need a new energy policy which takes cognizance of the results of market development in a more rational, less emotional way. In this respect, it should be limited henceforth to supporting renewable energies and technologies so as to enhance energy efficiency in line with market requirements. Fifthly, German energy policy must not commit the mistake of enforcing deregulation and, at the same time, exempting large segments of the market from competition. Thus, the planned expansion of renewable energies, and the increase in cogeneration to more than thirty percent of the German electricty generation, by way of quotas and revenues for electricity from these sources fed into the public grid, are incompatible with competition in Europe.

    In May 2003, the Federal Republic of Germany and the Republic of France awarded a contract to RHEINMETALL LANDSYSTEME GmbH, Germany), MBDA (France; THALES, France) for the joint development and manufacturing of a technology demonstrator for a vehicle-based close-in countermine system. The objective of this cooperation project, known as MMSR-SYDERA, is to show that, in a full-scale development program, it will be possible to fulfill the joint operational requirements issued by the German and French armies, which are based on the following missions: Fast route opening, Sensitive route opening and Area Clearing . In order to fulfill the three different missions and deal with an extensive array of mine threats, the MMSR-SYDERA countermine system combines two modes of countermine operation, i.e. triggering mines by decoying or detecting mines with sensors for low-order clearing. Thus, the plan calls for the MMSR-SYDERA system to be composed of five vehicles deployed in different configurations in a convoy on the roads to be cleared. This program takes advantage of the latest technologies to reach the objective performances: some innovative decoy tools already validated during real trials and optimized for MMSRSYDERA program, the latest ambitious technologies for detection and confirmation, and state-of-the-art remote-control capabilities, including tele-operation and semi-autonomous autofollow mode, with the highest established performances. An evaluation of the system demonstrator will be carried out at the beginning of 2007.

    Results of the fast growing wind energy market in 1994 are the turnover reaching more than 800 million DM, and the number of employees to about 3,700. In 1995 the manufacturers expect to need less than 4 employees to build and to install 1 MW rated power and to decrease the ratio of manufacturer's turnover per installed power unit to about 1900 DM/kW. In spite of this development it is expected that the turnover and the number of employees will increase due to the still fast growing market. (orig.)

    Highlights: • Solar gains exploitation by utilizing large glass facades and concrete core thermal energy storing capacity. • Efficient Building Energy Management in a well-insulated modern building construction. • Energy consumption reduction by maintaining user comfort. • High inertia large scale office building test case, located in Germany. - Abstract: Energy efficient passive designs and constructions have been extensively studied in the last decades as a way to improve the ability of a building to store thermal energy, increase its thermal mass, increase passive insulation and reduce heat losses. However, many studies show that passive thermal designs alone are not enough to fully exploit the potential for energy efficiency in buildings: in fact, harmonizing the active elements for indoor thermal comfort with the passive design of the building can lead to further improvements in both energy efficiency and comfort. These improvements can be achieved via the design of appropriate Building Optimization and Control (BOC) systems, a task which is more complex in high-inertia buildings than in conventional ones. This is because high thermal mass implies a high memory, so that wrong control decisions will have negative repercussions over long time horizons. The design of proactive control strategies with the capability of acting in advance of a future situation, rather than just reacting to current conditions, is of crucial importance for a full exploitation of the capabilities of a high-inertia building. This paper applies a simulation-assisted control methodology to a high-inertia building in Kassel, Germany. A simulation model of the building is used to proactively optimize, using both current and future information about the external weather condition and the building state, a combined criterion composed of the energy consumption and the thermal comfort index. Both extensive simulation as well as real-life experiments performed during the unstable German

    A joint venture for a nuclear power plant in operation or under construction poses for more open questions than a joint venture for a western-standard plant still to be erected. Both solutions have in common that resistance against the peaceful uses of nuclear energy in the former GDR is groving. It is too early to make a statement concerning joint ventures regarding other nuclear facilities, e.g. final repositories. That there will be no 'nuclear export' as such after unification does not imply a lot. The changes in eastern Europe are one of the biggest challenges in history. They are to be conquered by joining forces. This also goes for nuclear energy where not only safety but also the environment is at stake. Legislation should pay appropriate heed to these problems.

    Attempts to change people's lifestyles in order to adapt to and mitigate the consequences of climate change are not reasonable without considering the question whether climate change matters to people or not and which aspects of the topic are crucial to them and why. The study is based on two quantitative surveys among 188 Iranian students from three different high schools in Tehran and 188 German students from two educational institutions in Berlin and Bonn conducted in 2009 and 2010. The aim of the surveys was to find out about the attitudes on environmental protection and awareness and knowledge on climate change and its consequences among students and to analyse existing consumption behaviour regarding mobility and energy consumption and energy saving within their families. The study analyses and compares the results from German and Iranian students.

    The execution of the strategies of waste treatment and disposal calls for the laws and regulations on the obligations of the owners of equipments and facilities and of the state for securing safety and the final elimination of radioactive wastes, which are defined mainly in Article 9 of Atomgesetz and Section 2 (Article 44 - 48) of the order on protection from radiation. The owners of equipments and facilities of atomic energy technology shall limit the emission of radiation to about 6% of internationally permissible values, avoid uncontrolled emission without fail, inspect emission and submit reports yearly to government offices. The owners have attention obligations to utilize harmlessly produced radioactive residues and the expanded or dismantled parts of radioactive equipments or to eliminate orderly such things as radioactive wastes, only when such utilization is unable technically or economically, or not adequate under the protection aims of Atomgesetz. The possessors of radioactive wastes shall deliver the wastes to the accumulation places of provinces for intermediate storage, to the facilities of the Federal Republic for securing safety or final storage, or the facilities authorized by government offices for the elimination of radioactive wastes. Provinces shall install the accumulation places for the intermediate storage of radioactive wastes produced in their territories, and the Federal Republic shall set up the facilities for securing safety and the final elimination of radioactive wastes (Article 9, Atomgesetz).

    Hand surgery often needs only a short length of stay in hospital. Patients' comorbidity is low. Many hand surgery procedures do not need inpatient structures. Up until 2006 special procedures of hand surgery could not be coded. The DRG structure did not separate very complex and less complex operations. Specialized hospitals needed a proper case allocation of their patients within the G-DRG system. The DRG structure concerning hand surgery increased in version 2007 of the G-DRG system. The main parameter of DRG splitting is the complexity of the operation. Furthermore additional criteria such as more than one significant OR procedure, the patients' age, or special diagnoses influence case allocation. A special OPS code for complex cases treated with hand surgery was implemented. The changes in the DRG structure and the implementation of the new OPS code for complex cases establish a strong basis for the identification of different patient costs. Different case allocation leads to different economic impacts on departments of hand surgery. Whether the new OPS code becomes a DRG splitting parameter has to be calculated by the German DRG Institute for further DRG versions.

  17. Residual risks of the 13th amendment to the German Atomic Energy Act

    International Nuclear Information System (INIS)

    2011-01-01

    The 13th amendment to the German Atomic Energy Act, which was adopted by the German federal parliament on June 30 and entered into force on August 6, 2011, must be judged in the light of its genesis. Federal Chancellor Merkel, in her government declaration of June 9, 2011, had mentioned topics such as residual risk, safety standards, and risk assumptions, on which the federal government, in the week after the event of March 11, 2011, had commissioned the Advisory Committee on Reactor Safeguards (RSK) to conduct a comprehensive safety review of all German nuclear power plants, and appointed an Ethics Committee to write an opinion on safe energy supply. On the basis of quickly drafted reports, the federal cabinet, without any international harmonization (EU, IEA), adopted a draft opt out law on June 6, 2011. How should the declarations by the Federal Chancellor on June 9, 2011 be classified in terms of atomic energy law? In her words, it all revolved around the residual risk. The debate, which has been shifted to the realm of constitutional law, is open to considerations and steps to attack the new opt out law on grounds of material unconstitutionality (violation of the property guarantee under Sec. 14 or the principle of equality under Art.3 of the Basic Law). As far as final storage is concerned, the amendment to the German Atomic Energy Act announced still for this year, also for transposition of the EURATOM Directive of July 19, 2011 about nuclear waste management, the ''re-assessment of the residual risk'' is not likely to play a role. All these events are reminiscent of a sentence by former Federal Chancellor Schmidt: ''The history of the NATO dual-track decision remains a textbook case showing that even in a democracy emotions using ethical arguments, mixed with demagogy, can become strong enough to cast aside balanced reason.'' There is also a distinction by Max Weber between ''ethics of ideology'' and ''ethics of responsibility''. (orig.)

  19. Renewable energy and CCS in German and European power sector decarbonization scenarios

    Energy Technology Data Exchange (ETDEWEB)

    Ludig, Sylvie

    2013-11-06

    system costs are lower when transmission and storage are available. Restrictions on transmission expansion induce high amounts of storage since high local shares of solar PV lead to large output variations. In contrast, a highly interconnected European power grid allows for optimized renewable power generation siting in regions with highest potentials, which requires large-scale transmission expansions but limits total power system costs. Results from a detailed study for Germany show that the level of power demand is strongly relevant for the realization of high renewable shares and ambitious decarbonization targets. A broad technology portfolio allows to hedge against the failure to meet efficiency goals for electricity demand. CCS is necessary to reach ambitious government targets if power demand is not sufficiently decreased by efficiency measures, as is offshore wind energy. Even in case of decreasing demand, at least one of both technologies needs to be available. The choice of transmission expansion corridors is strongly influenced by technology availability: in scenarios without offshore wind energy, north-south interconnections, which are crucial in all other scenarios, only play a minor role. The studies in this thesis show that a large-scale decarbonization of the German and European power sectors is achievable through large shares of renewable energy technologies for electricity generation. CCS is not a prerequisite for successful CO{sub 2} emission strategies, but allows reaching mitigation targets at a lower cost. A portfolio of renewable energy integration options is essential to manage temporal and spatial fluctuations; the optimal technology mix is determined by the underlying power system.

    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

  1. Under new auspices: transition process and cooperation models in the French-German energy relations

    Cooperation on energy matters has been a matter of priority in Franco-German consultations for some time. Not only is close coordination advisable due to the geographic proximity of Europe's two largest national energy markets. Their growing degree of economic (and energy) integration makes it necessary. The significance of energy policy for industrial policy on both sides of the Rhine is unmistakable. While policy approaches in the two countries' energy sectors have differed in the past and in some ways continue to do so, this has not diminished the topic's relevance or lessened the importance of cross-border cooperation. What is new is that both states are now pursuing the same goal: energy transformation (known as Energiewende, or 'transition energetique', depending on which side of the Rhine you are on). There are therefore plenty of good reasons to strive for closer cooperation on matters of energy policy and, in doing so, help bridge some of the gaps in the sputtering Franco-German relationship.

    This debate is based on a study recently published by Ifri's Energy Program (Les relations franco-allemandes dans le secteur de l'energie, by Jan Horst Keppler, Sophie Meritet and Kristina Notz). Franco-German energy relations are often dominated by debates on nuclear power and, for many observers, the two countries seem far apart on this question. Indeed, very different political decisions have been made by either country on the issue. Surprisingly, opinion polls have shown that public opinion on nuclear energy is quite similar in both countries. Furthermore, the cooperation between Areva and Siemens in the nuclear field is one of the best examples of Franco-German industrial cooperation. In more general terms, France and Germany have a quite different energy mix and hence both countries have divergent positions concerning some aspects of European energy policy. Positions on nuclear energy phasing-out, electricity networks, energy security and gas supply, fuel substitution, climate change and the development of renewable energy sources, etc. are discussed

    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.

  6. German coal and the Ruhrkohle AG in an energy policy context

    International Nuclear Information System (INIS)

    Hessling, M.

    1993-01-01

    German coal output has fallen since 1957. The Ruhrkohle AG was established in 1968 to reorganise the mining industry in the Ruhr district. It comprised 52 collieries with 186000 employees. The number of collieries was reduced to 15 and the number of employees to 79000 by 1992. Output fell from 91 to 46 mill. t/a. A time frame was created by Coal Concept 2005. The contribution of German coal to energy supply has been reduced for financial policy reasons, but the mining industry has acquired long-term prospects. The required retrenchment is already extremely difficult to implement and handle according to the agreements of November 1991, but the current steel crisis has necessitated that the measures be brought forward.

    2014-06-01

    This French-German conference on hydrogen energy was jointly organised by the French embassy in Berlin and the French-German office for renewable energies. The conference brought together about 200 scientific experts, industrialists and politicians from both countries. The conference approached first the regulatory aspects of hydrogen energy in both countries. Then, several R and D presentations were given by representatives of industrial groups, small companies and research organisations about some technological aspects of PEM fuel cells, solid storage, and materials for H 2 production. Next, some applications of hydrogen energy were discussed in particular in transportation systems. Finally, the last part of the conference was devoted to the challenges and perspectives of hydrogen energy, together with its social acceptability. This document brings together the different presentations (slides) given by the participants: 1 - Hydrogen Energy and Fuel Cells in France Today, and prospective (Luc Bodineau); 2 - The situation of Energy Policy in Germany and the challenges for the Hydrogen Technology (Georg Menzen); 3 - PEM-Electrolysis - a technological bridge for a more flexible energy system (Gaelle Hotellie); 4 - Unlocking the Hydrogen Potential for Transport and Industry (Peter Erich Arnold); 5 - Hydrogen storage possibilities - the solid storage example (Pascal Mauberger); 6 - Innovative Materials and Manufacturing Technologies for H2 Production and H 2 Storage (Lars Roentzsch); 7 - Scientific development and industrial strategy, experience feedback from the Myrte platform and perspectives in the framework of the energy transition (Philippe Poggi, Thierry Gervais); 8 - 'Power to Gas' - Important partner for renewables with big impact potential (Guenther Schneider); 9 - Developing a Hydrogen Infrastructure for Transport in France and Germany.

    2013-01-01

    Stocks of German renewable energy companies have commonly been regarded as lucrative investment opportunities. Their innovative line of business initially seemed to promise considerable future earnings. As shown by two powerful bubble tests, the positive sentiment for renewable energy stocks even led to explosive price behavior in the mid-2000s. However, intense sector competition and the economic downturn following the global financial crisis erased profit margins to a large extent. As a result, the former fad stocks have recently turned into losers, loading negatively on price momentum and delivering significantly negative Carhart four-factor alphas. The radical shift in Germany's energy policy following the 2011 Fukushima nuclear disaster in Japan could thus only temporarily halt the continuing decline in alternative energy stock prices. - Highlights: ► We examine the return behavior of German renewable energy stocks between 2004 and 2011. ► The former fad stocks have recently turned into loser stocks. ► They produced significantly negative Carhart four-factor alphas since 2008. ► The price behavior before 2008 was considerably driven by explosiveness. ► Upbeat sector sentiment in the mid-2000s might have caused this speculative bubble

  12. Effects of European energy policy on German nuclear phase-out policy

    International Nuclear Information System (INIS)

    Buedenbender, Martin

    2009-01-01

    After the election of the new German government on September 27th, 2009, the nuclear power phase-out decision appears back on top of the political agenda. Hence, an up to date survey of all relevant arguments seems absolutely necessary. In that matter, the scope should not remain national but should also take the European dimension into account. On the European level, a position in favour of nuclear power becomes apparent. Recent political decisions among the 27 member states show a renaissance of atomic energy. EU-Parliament, EU-Commission and EU-Council have all voted for the extensive, long term use of nuclear power in Europe. With its phase-out decision still valid, Germany is part of a minority in Europe. Germany is part of a European market for electricity whose national barriers will blur more and more in the future to form a fully integrated pan-European market in the end. Since nuclear power will provide a major share of the European electricity generation mix, Germany will always be supplied with atomic energy in the long term. This is imperative, regardless of nuclear power plants operating within the borders of Germany or not. Shutting down these facilities in Germany will hence not make the risks associated with atomic energy disappear. It will only add energy-technical challenges to assure long-term supply security. Thus, the new German government should withdraw the phase-out decision. (orig.)

  13. The energy demand in the British and German industrial sectors. Heterogeneity and common factors

    Agnolucci, Paolo

    2009-01-01

    This paper estimates energy demands for the German and British industrial sectors over the 1978-2004 and the 1991-2004 samples. From time series models we can conclude that there is a considerable variation in the value of the coefficients across sectors, even though energy demands with sensible parameters can rarely be estimated. When using a panel approach, the ability of some estimators to allow for diversity across subsectors was an important factor in explaining the estimates for price elasticity. On the other hand, correlation across panel members or common factors did not markedly influence our results. With regard to the estimated parameters, our preferred choice for elasticity of economic activity and price in the longer sample is 0.52 and - 0.64. Similar values are found in the case of the shorter samples. Bearing in mind the high price elasticity, energy taxes can be considered an effective strategy for reducing energy consumption. (author)

  14. The diverging paths of German and United States policies for renewable energy: Sources of difference

    International Nuclear Information System (INIS)

    Laird, Frank N.; Stefes, Christoph

    2009-01-01

    The United States and Germany started out with very similar policies for renewable energy after the energy crisis of the 1970s. By the year 2000 they were on very different policy paths and, as a result, the German renewable energy industry has moved well ahead of that in the United States, both in terms of installed capacity in the country and in terms of creating a highly successful export market. In this paper, we reject some of the conventional explanations for this difference. Instead, these differences arise from the intersection of contingent historical events with the distinctive institutional and social structures that affect policy making in each country. Our analysis of the historical path-dependent dynamics of each country suggests that those who wish to further renewable energy policy in the United States need to take into account these institutional and social factors so that they will better be able to exploit the next set of favorable historical circumstances.

  15. Long-term impacts of battery electric vehicles on the German electricity system

    Heinrichs, H. U.; Jochem, P.

    2016-05-01

    The emerging market for electric vehicles gives rise to an additional electricity demand. This new electricity demand will affect the electricity system. For quantifying those impacts a model-based approach, which covers long-term time horizons is necessary in order to consider the long lasting investment paths in electricity systems and the market development of electric mobility. Therefore, we apply a bottom-up electricity system model showing a detailed spatial resolution for different development paths of electric mobility in Germany until 2030. This model is based on a linear optimization which minimizes the discounted costs of the electricity system. We observe an increase of electricity exchange between countries and electricity generated by renewable energy sources. One major result turns out to be that electric vehicles can be integrated in the electricity system without increasing the system costs when a controlled (postponing) charging strategy for electric vehicles is applied. The impact on the power plant portfolio is insignificant. Another important side effect of electric vehicles is their substantial contribution to decreasing CO2 emissions of the German transport sector. Hence, electric mobility might be an integral part of a sustainable energy system of tomorrow.

    2010-01-01

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

    2016-01-01

    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. [de

    HIV associated neuromanifestations are of growing importance in the in-patient treatment of HIV infected patients. In Germany, all in-patients have to be coded according to the ICD-10 classification and the German DRG-system. We present recommendations how to code the different primary and secondary neuromanifestations of HIV infection. These recommendations are based on the commentary of the German DRG procedures and are aimed to establish uniform coding of neuromanifestations.

    The Energy Transition (''Energiewende'') is one of the hot topics of the political debate in Germany for some years. As a consequence of ongoing European integration, EU level politics have gained growing importance. The focus of this study is on the interaction of German and EU energy and climate policies. How have German actors influenced EU policy-making processes and in how far are EU policies relevant for national policy-making in Germany? Three case studies look at processes in the fields of electricity market regulation, renewable energy policy and climate protection between 2007 and 2013.

    To what extend are renewable energy sources used in German hospitals? This is the main objective, this is paper is dealing with. The energy consumption profile is very specific in hospitals. In a questionnaire based study, 79 hospitals have been questioned to elucidate the current situation in German hospitals with respect to energy consumption, and to get an idea of the proportion of alternative energy sources already in use. Our analysis reveals that 14% of the hospitals analysed are already using renewable energy sources. Main sources already utilized are photovoltaic, solar thermal devices, and to a lower extend geothermic energy as well comes into operation. Almost three quarters of the questioned institutions claim, they are aware of funding possibilities and the option of contracting with respect to providing financial support in relation to aquisition of new establishments of alternative energy systems within their institution. Roughly half of the hospital's technical supervisors are aware of the precise energy potential of their institution. The situation about information and awareness with respect to possibilities related to the usage of green energy is deficient and should be improved, but the openness with respect to the topic in general seems to be very positive and advantage of that climate should be taken. Our survey allowed to get an initial estimate on the green energy situation in German hospitals. The focus of the discussion is channeled towards the environmental aspects of the energy production. The survey data allow to conclude that the current information situation is deficient. The data further provide insight into what are the main barriers with respect to the use of renewable energy. Based on our results future analyses can not focus on specific aspects and further evaluate approaches allowing to extend the usage of alternative energy sources in hospitals. (orig.)

  5. The impact of energy performance certificates: A survey of German home owners

    2012-01-01

    The building sector accounts for about 40% of the final energy consumption in Germany. At the same time, the sector is regarded as one of the most cost-effective options for saving CO 2 emissions. To target this potential, the European Union introduced energy performance certificates (EPC). EPCs should provide clear information about the energy performance of buildings to building purchasers, owners and tenants. This study analyses, in how far EPCs have helped purchasers of owner-occupied dwellings in Germany to incorporate energy efficiency in their purchasing decisions. The results suggest that the effectiveness of EPCs is limited. Main reasons are first, that the certificates are not helpful for understanding the financial implications of energy efficiency. Second, EPCs are not viewed for most buildings due to their legal status. Third, energy efficiency is only a minor purchasing criterion for dwelling purchases. The results of the study however also point to the potential of EPCs, as these barriers can be removed. From 2013 onwards the use of the EPC will be increased due to the new EU Energy Performance of Buildings Directive (EPBD). Changes to the design of the EPC could further increase the importance of energy performance certificates and of energy efficiency. - Highlights: ► Study examines impact of EU energy performance certificate on German housing market. ► Low impact of EPC on purchasing decisions found. ► Reasons are limitations in design, legal status, importance of energy efficiency. ► Study is relevant because of low previous coverage and because of update of directive.

    2014-06-01

    Full Text Available The article presents the properties of exogenous word-formation system taking into account the existence of two word-formation systems in modern German. On the basis of foreign research which reveal modern trends in German word-formation connected with the internationalization and the development of new European Latin language. The author defines key features of exogenous word-formation, i.e. foreign origin of wordformation units, unmotivated units, unmotivated interchange in base and affixes as well as limited distribution rules in combination with German word-formation. The article analyzes various approaches to word-division, as well as motivated and unmotivated interchange of consonants in bases and in affixes. Unmotivated interchange showcases a special status of the exogenous word-formation within German. Another item covered by the article is the issue of confix. The article has opinions of researchers about correctness of its separation and a list of its features. The author presents his definition of confix: a confix is a bound exogenous word-formation unit with a certain lexical and semantic meaning and joining other units directly or indirectly (through linking morpheme -o-, which is able to make a base. Moreover, some confixes are able to participate at word-combination and have unlimited distribution. So far, confix showcases the integration of exogenous word-formation and traditional German word-formation. The research proves the special status of exogenous word-formation in German. Its results can be used as a base for further analysis of co-existing word-formation systems in German and determination of their characteristic features.

  7. What are community energy companies trying to accomplish? An empirical investigation of investment motives in the German case

    Holstenkamp, Lars; Kahla, Franziska

    2016-01-01

    Community energy has become an increasingly important issue in academia and in energy policy circles worldwide. Citizens jointly investing in and operating renewable energy installations have played an essential role in countries such as Germany or Denmark. Building on and extending previous studies, we collect survey data on investment motives for a stratified random sample of German community energy companies. Structural variables are selected using a socio-ecological-technical systems framework. This study aims to identify differences within the community energy sector to better understand investment behaviour and the effects of policy changes. Despite the small sample coverage at the individual member level, the preliminary results of this study suggest that, first, community energy forms a specific type of social investment and that, second, there are significant differences between community energy companies, especially regarding the assessment of the return motive. This motive plays a more prominent role in limited partnerships than in cooperatives and for community wind than for companies focusing on solar or biomass. While these and other factors are highly interrelated, our data indicate that the social setting and geographical and climatic conditions are the critical ones here. These findings may guide further research. - Highlights: • Community energy companies form a specific part of the impact investment sector. • Differences in the valuation of investments exist mainly regarding the return motive. • There are significant differences between North vs South and cooperatives vs LPs. • The return motive plays a higher role for community energy founded 2009–2011. • These differences have to be taken into account when assessing policy changes.

  8. A True Proteus: A history of energy conservation in German science and culture, 1847-1914

    Wegener, F. D. A.

    2009-11-01

    This thesis follows the career of the law of energy conservation in German science and culture between 1847 and 1914. There is an interesting contrast between the initial reception of Hermann Helmholtz’ 1847 treatise ‘Über die Erhaltung der Kraft’, which was rejected by the editor of the Annalen der Physik, and its later status as a classic of science. ‘Energy’ was the shared concept of the disciplines. It was used by physiologists, physicists, psychologists, sociologists and philosophers. Moreover, the law of energy conservation also made a huge cultural impact. The period around 1900 has justly been called an energetic era. Why did the law of energy conservation become such a universal success? The obvious way to explain this success would be to say: because it is true, and subsequently comment upon its great scientific value. This thesis adopts a different perspective. It adopts Wittgenstein’s definition of meaning as use in language. Consequently, the meaning of the law is only referred to in relation to the way in which it was put to use in communicative practice. From this perspective it is immediately evident that the understanding of the law of energy conservation was subject to considerable change. Helmholtz initially conceptualized the law in terms of atoms and forces; Gustav Kirchhoff and Ernst Mach, rejected atoms and forces as hypothetical entities and they preferred to use the more mundane concept of work instead; Wilhelm Ostwald, finally, thought of energy as an immaterial substance. This thesis meticulously follows the changes in use and understanding to which the law was subject as it penetrated German science and culture. Communication and interests, rather than natural essences, are the central explanatory concepts of the thesis. From 1847 onwards Helmholtz and Du Bois-Reymond actively sought to spread the law of energy conservation among their colleagues and the general public. They told their fellow physiologists, for example, that

  9. Tele-Coupling Energy Efficiency Polices in Europe: Showcasing the German Governance Arrangements

    Marc Ringel

    2018-05-01

    Full Text Available Climate change entails many situations of tele-coupling. We analyze an example in the field of European climate and energy policy. The EU aims at an almost full decarbonisation of its economy by 2050. Achieving this objective asks for transforming the energy sectors of EU Member States. These are responsible for 80% of carbon emissions. Further to this policy coupling, the EU transformation objectives have to be implemented by the Member States, regions and local actors. This proves especially complex in the field of energy efficiency. Here, a variety of policy instruments and actors are in place. In our contribution, we investigate in the question how multi-level governance arrangements in the energy efficiency field are designed. We focus on Germany as example for a federal state setting. Our review method comprises literature content analysis, primary sources, expert interviews and an in-depth screening of the German Sustainable Energy Action Plans. We find that formal vertical coordination has been successfully backed up by horizontal and especially informal governance mechanisms, leading to a model of polycentric governance. This model might serve as blueprint for other multi-level governance arrangements. Yet, we find that the “last mile” of this coordination still needs strengthening: Local actors need more active engaging and empowering to reap the full potential of the governance arrangements.

  10. Future prospects of the brown coal of central and east Germany in the all-German energy industry. Perspektive der mittel- und ostdeutschen Braunkohle in der gesamtdeutschen Energiewirtschaft

    Against a background of different basic conditions the energy industry in the former German Democratic Republic during the last 30 years underwent an entirely different development to that which occurred in the former Federal Republic of Germany. In the Federal Republic, oriented to a free market system, a structural change took place from the 1960s onwards, that is to say, away from solid fuels and towards a mixed energy utilization, in which mineral oil and natural gas in particular play a significant part. The principal market for coal, especially brown coal, is the important power generation sector. The German Democratic Republik, on the other hand, in keeping with its autarchic energy policy relied on the only source of energy available in large quantities, namely brown coal. The reason for this lay in the fact that the system made it impossible to participate in an international exchange of commidities. As a result of the ton-quota ideology and inefficiency in all sectors of energy winning, conversion and utilization the consumption both of primary energy and also of electricity in the former German Democratic Republic was high compared to that in the Federal Republic, and this in spite of the fact that the per capita economic strength was less than half that of the Federal Republic. Two changes are likely to occur in future. On the one hand, a medium-term mixed energy utilization will develop in the primary energy sector, as has been the case in the Federal Republic. On the other hand, it can be assumed that simultaneously with this development consumption will tend to decrease. As in the Federal Republic, the future prospect to brown coal, which has hitherto played a dominating role, will in the first place lie in its utilization in conjunction with the power industry and only secondarily on the thermal energy market.

    Significant reduction of CO{sub 2}-emissions is essential in order to prevent a worsening of ongoing climate change. This thesis analyses two different pathways for the mitigation of CO{sub 2}-emissions in electricity generation. It focuses on the calculation of CO{sub 2}-mitigation costs of renewable energy sources (RES) as well as of power plants with carbon capture and storage (CCS). Under the frame of long-term CO{sub 2} reductions targets for the German electricity sector future CO{sub 2}-mitigation costs are calculated on a system-based and a technology-based approach. The calculations show that RES have lower system-based mitigation costs in all scenarios compared to a system based on CCS. If the retrofit of power plants is taken into consideration, the results are even more clearly in favour of RES. Further, the thesis investigates whether CCS can serve as a bridge towards a sustainable energy system based on RES. Findings of different scientific disciplines suggest that CCS is not the optimal choice. These findings lead to the conclusion that CCS cannot support an easier integration of RES. CCS rather has the potential to further strengthen the fossil pathway and delaying the large-scale integration of RES. Hence, CCS is rather unsuited as a bridging technology towards a system mainly based on RES.

    2013-08-01

    Studies assessing the quality of the German health-care system in an international comparison come to different results. Therefore, this review aims to investigate how the German health-care system is evaluated in comparison to other health-care systems by reviewing international publications. Results show starting points for ways to improve the German health-care system, to maintain and expand its strengths as well as to derive strategies for solving identified problems. A systematic review searching different databases [library catalogues, WorldCat (including MEDLINE and OAIster-search), German National Library, Google Scholar and others]. Search requests were addressed to English or German language publications for the time period 2000-2010 (an informal search was conducted in October 2011 for an update). Results of the identified studies were aggregated and main statements derived. In total, 13 publications assessing the German health-care system in an international comparison were identified. These comparisons are based on 377 measures. After aggregation, 244 substantially different indicators remained, which were dedicated to 14 categories. It became apparent that the German health-care system can be characterised by a high level of expenses, a well-developed health-care infrastructure as well as a high availability of personal and material resources. Outcome measures demonstrate heterogeneous results. It can be stated that, particularly in this field, there is potential for further improvement. The utilisation of health-care services is high, the access is mostly not regulated and out of pocket payments can pose a barrier for patients. Waiting times are not regarded as a major weakness. Although civic satisfaction seems to be acceptable, a large portion of the citizens calls for elementary modifications. Especially, more patient-centred health-care delivery should be addressed as well as management of information and the adoption of meaningful electronic

    Transcranial sonography of the substantia nigra for diagnosing premotor stages of Parkinson disease has been attracting increasing interest. Standard reference values defining an abnormal increased echogenic size (hyperechogenicity) of the substantia nigra have been established in several populations using high-end stationary ultrasound systems. It is unknown whether a portable ultrasound system can be appropriately used and how the Filipino population would compare with the well-studied white population. We prospectively studied substantia nigra echogenic sizes and third ventricle widths in 71 healthy adult German participants and 30 age- and sex-matched Filipino participants using both a well-established stationary ultrasound system (in the German cohort) and a recently distributed portable ultrasound system (in both ethnic cohorts). Mean substantia nigra echogenic sizes, cutoff values defining abnormal hyperechogenicity, and intra-rater reliability were similar with both systems and in both ethnic cohorts studied. The Filipino and German participants did not differ with respect to the frequency of insufficient insonation conditions (each 3%) and substantia nigra hyperechogenicity (10% versus 9%; P = .80). However, third ventricle widths were smaller in the Filipino than the German participants (mean ± SD, 1.6 ± 1.1 versus 2.4 ± 1.0 mm; P = .004). The frequency of substantia nigra hyperechogenicity appears to be homogeneous in white and Asian populations. Screening for this feature may well be performed with a present-day portable ultrasound system.

  4. German Democratic Republic State system of accounting for and control of nuclear material

    The system of accountancy for and control of nuclear material in the German Democratic Republic (GDR) with its legal bases and components is embedded in the overall State system of protection in the peaceful uses of nuclear energy. As the competent State authority, the Nuclear Safety and Radiation Protection Board of the GDR is also responsible for meeting the GDR's national and international tasks in the control of nuclear material. At enterprise level, the observance of all safety regulations for nuclear material, including the regulations for the control, is within the responsibility of managers of establishments, which are in any way concerned with the handling of nuclear material. To support managers and to function as internal control authorities, nuclear material officers have been appointed in these establishments. Design information, operating data, physical inventory of nuclear material and the respective enterprise records and reports are subject to State control by the Nuclear Material Inspectorate of the Nuclear Safety and Radiation Protection Board. This Inspectorate keeps the central records on nuclear material, forwards reports and information to, and maintains the necessary contacts with, the IAEA. For the nuclear material in the GDR four material balance areas have been established for control purposes. To rationalize central recording and reporting, electronic data processing is increasingly made use of. In a year-long national and international control of nuclear material, the State control system has stood the test and successfully co-operates with the IAEA. (author)

  7. Advocates or cartographers? Scientific advisors and the narratives of German energy transition

    International Nuclear Information System (INIS)

    Leipprand, Anna; Flachsland, Christian; Pahle, Michael

    2017-01-01

    Political debate on energy in Germany has been shaped by two historically opposed discourses, one pushing for a transition to renewables, the other holding on to the status quo. Scientific policy advice (SPA) has been involved in their evolution from the beginning. This paper draws on the Advocacy Coalition Framework and on discourse and narrative theory to study the role of SPA in recent German energy policy. We explore 1) whether scientific advisors have been members of advocacy coalitions, and 2) how their contributions may have interacted with the evolution of the discourses and major narratives. We perform a qualitative text analysis of 50 SPA reports published between 2000 and 2015. We find that the majority of studies clearly take sides in the debate, and that in most cases the reports’ positions are fully transparent. Despite the polarization, SPA provides differentiated information on key aspects of the discourses, and alternative design options for policy instruments. We conclude that SPA contributions have improved the conditions for political consensus and compromise. Collectively, SPA studies provide a basis for mapping different policy pathways and their consequences. In the future, SPA should address additional critical issues such as coal phase-out and international leadership. - Highlights: • We explore the role of scientific policy advice in Germany's energy transition. • There is widespread, mostly transparent advocacy in scientific advisory reports. • We conclude that scientific policy advice has facilitated dialogue and compromise. • We discuss implications for future advisory activity and further improvements.

    This paper gives an account of the impacts of the liberalisation of the German electricity market and describes the existing energy policy and recent responses to the liberalisation with respect to the electricity sector. In the first section, electricity supply, electricity consumption and the structure of the electricity market are described. In the second section, the legal framework for the liberalisation of the electricity market in Germany and the consequences for prices, market structure, legal form of utilities, investment, cogeneration and products offered are presented. The final section first provides an overview of the national and international climate policy targets as well as the agreed upon phase-out of nuclear energy. Finally, existing electricity policy instruments and policy responses to the liberalised electricity market are reported. These policy instruments include support for hard coal and lignite, the new ecological-tax reform, the promotion of renewable energy sources, support for cogeneration, voluntary agreements, and the flexible mechanisms for greenhouse gas emission reductions as introduced in the Kyoto protocol.

  11. Feasibility and potential of thermal demand side management in residential buildings considering different developments in the German energy market

    International Nuclear Information System (INIS)

    Wolisz, Henryk; Punkenburg, Carl; Streblow, Rita; Müller, Dirk

    2016-01-01

    Highlights: • A scenario analysis for the German energy market in the year 2030 is performed. • Growing demand for flexible electric capacities is identified in all scenarios. • Significant potential for domestic demand side management is identified. • A distinct potential for dynamic operation of domestic supply systems is found. • The necessity for a quick introduction of smart metering and control is found. - Abstract: A transition in the electricity market is required to manage the volatility of increasing renewable energy generation. These fluctuations can be faced with flexible consumption through Demand Side Management (DSM), establishment of further centralized storage capacities and provisioning of dynamic back up generation capacities. At least the latter two options can impose large establishment and operation costs upon the electricity market. Therefore, the feasibility and the resulting potential of coupling the electricity grid with the thermal supply of residential buildings is analysed in this paper. Thereby, inexpensive and widespread thermal storage capacities could be used to improve the integration of dynamic renewable electricity generation. In this paper the technical and economical key impact factors for such thermal DSM approach are elaborated. Based on a literature review, the identified key factors are aggregated to form consistent scenarios of the German “Energiewende” (turnaround in energy policy). The practicability and possible magnitude of the intended DSM is then analysed based on the identified scenarios. All resulting scenarios highlight the growing demand for a flexible electricity market. Especially in scenarios with strong growth of renewable electricity generation, up to 45 GW of flexible electric capacities would be required in Germany by the year 2030. Furthermore, the analysis demonstrates that independently of the energy market development, it is very likely that electricity coupled supply systems will

    Energy Transition has already led to changes in the energy landscape and will continue to initiate changes. However, it also raises questions that need to be answered: What are the objectives to be achieved by 2020, what are the objectives of a more or less threatening failure? Which instruments and measures have proved to be helpful, which to be (largely) ineffective? What caused the likely heterogeneous goal fulfillment? What are the relevant exogenous causes, which are characterized by the fact that the national energy policy can not have any influence on it? And what are the endogenous causes, which lead to concrete indications of a necessary re-control of the energy transition? Obviously, the answers to these questions are relevant not only from a historical perspective, but also for the question of how the energy tansition will be successfully continued in the 2020-2030 period, and how possible failures can be avoided or at least reduced. [German] Die Energiewende hat bereits heute zu Umbruechen in der Energielandschaft gefuehrt und wird auch weiter Veraenderungen anstossen. Dennoch wirft sie auch Fragen auf, die beantwortet werden wollen: Welche Ziele duerften bis zum Jahr 2020 erreicht werden, bei welchen Zielen droht eine mehr oder weniger starke Verfehlung? Welche Instrumente und Massnahmen haben sich als hilfreich erwiesen, welche als (weitgehend) wirkungslos? Worauf ist die voraussichtlich heterogene Zielerfuellung zurueckzufuehren? Was sind die dafuer massgebenden exogenen Ursachen, die dadurch gekennzeichnet sind, dass die nationale Energiepolitik darauf grundsaetzlich keinen Einfluss nehmen kann? Und was sind die endogenen Ursachen, woraus sich konkrete Hinweise auf ein erforderliches Nachsteuern der Energiewende ergeben? Offensichtlich sind die Antworten auf diese Fragen nicht nur aus historischer Perspektive relevant, sondern auch fuer die Frage, wie die Energiewende im Zeitraum 2020 bis 2030 erfolgreich weitergefuehrt und wie allfaellige

    The German DRG-System was advanced into version 2009. For orthopedic and trauma surgery significant changes concerning coding of diagnoses, medical procedures and concerning the DRG-structure were made. Analysis of relevant diagnoses, medical procedures and G-DRGs in the versions 2008 and 2009 based on the publications of the German DRG-institute (InEK) and the German Institute of Medical Documentation and Information (DIMDI). Changes for 2009 focussed on the development of DRG-structure, DRG-validation and codes for medical procedures to be used for very complex cases. The outcome of these changes for German hospitals may vary depending in the range of activities. G-DRG-System gained complexity again. High demands are made on correct and complete coding of complex orthopedic and trauma surgery cases. Quality of case-allocation within the G-DRG-System was improved. Nevertheless, further adjustments of the G-DRG-System especially for cases with severe injuries are necessary.

    Full Text Available This paper explores the integration of different social fields within the German Energy Transition (Energiewende discourse in the election year 2013 by analysing the hyperlink structures online. Energiewende describes the fundamental transition from non-renewable energy to sustainable sources. This goal is both ambitious and controversial. Numerous stakeholders try to make their voices and interests heard and as such politics has to both disseminate and collect information in order to include all relevant groups from different social fields in the political process. This discourse is also visible online. By analysing the hyperlink structures we are able to see the attention distribution of different actor groups in the network. This study shows that most actors tend to link within their own social field and do not aim for a more integrated public sphere. Especially political actors appear to be lone warriors who neither look left or right and mostly link within their own party and ignore other actors. Whereas social field as the media or public administration are relevant within the network we find that scientific actors are ignored by all fields, except for their own.

    As this publication shows, recent changes in the energy sector have been so momentous that its development over the past years can hardly be compared with that of any other branch of industry. The need to meet a continuously growing body of regulatory requirements, technical innovations such as smart metering infrastructures and the complex tasks associated with an efficient decentralised energy supply all place high demands on the energy sector and its IT infrastructure. Especially the technologies surrounding smart metering confront companies of the energy sector with great challenges. Optimisation of process costs along the entire value chain will in future be an important ingredient to successful business in the sector. Thus, selecting the right accounting and billing solutions and putting them to their best possible use is a prerequisite for successful market cultivation. Based on an empirical study the present publication undertakes to determine what factors are relevant in selecting and operating IT solutions in the energy sector and what marketing design concepts software producers should opt for in order to ensure long-term customer satisfaction and hence loyalty.

    Peak and average energy usage in domestic and industrial environments is growing rapidly and absence of detailed energy consumption metrics is making systematic reduction of energy usage very difficult. Smart energy management system aims at providing a cost-effective solution for managing soaring energy consumption and its impact on green house gas emissions and climate change. The solution is based on seamless integration of existing wired and wireless communication technologies combined with smart context-aware software which offers a complete solution for automation of energy measurement and device control. The persuasive software presents users with easy-to-assimilate visual cues identifying problem areas and time periods and encourages a behavioural change to conserve energy. The system allows analysis of real-time/statistical consumption data with the ability to drill down into detailed analysis of power consumption, CO2 emissions and cost. The system generates intelligent projections and suggests potential methods (e.g. reducing standby, tuning heating/cooling temperature, etc.) of reducing energy consumption. The user interface is accessible using web enabled devices such as PDAs, PCs, etc. or using SMS, email, and instant messaging. Successful real-world trial of the system has demonstrated the potential to save 20 to 30% energy consumption on an average. Low cost of deployment and the ability to easily manage consumption from various web enabled devices offers gives this system a high penetration and impact capability offering a sustainable solution to act on climate change today.

    By subjecting to the massive usage of electrical energy in Malaysia, energy efficiency is now one of the key areas of focus in climate change mitigation. This paper focuses on the development of an energy efficiency system of household electrical appliances for residential areas. Distribution of Questionnaires and pay a visit to few selected residential areas are conducted during the fulfilment of the project as well as some advice on how to save energy are shared with the participants. Based on the collected data, the system developed by the UTHM Energy Team is then evaluated from the aspect of the consumers' behaviour in using electrical appliances and the potential reduction targeted by the team. By the end of the project, 60% of the participants had successfully reduced the electrical power consumption set by the UTHM Energy Team. The reasons for whether the success and the failure is further analysed in this project.

    Atomic energy law remains a living, fascinating subject matter. Nearly 200 participants were convinced of this impression at the 14{sup th} German Atomic Energy Law Symposium held in Berlin on November 19-20, 2012. Under the scientific chairmanship of Professor Dr. Martin Burgi, Ludwig Maximilian University of Munich, the German Federal Ministry for the Environment, Nature Conservation and Nuclear Safety (BMU), after an interruption of 5 years, again organized a scientific conference about practice-related topics of atomic energy and radiation protection law. Atomic energy law once again proved to be a reference area for sophisticated issues of constitutional law and administrative law above and beyond its technical confines. The agenda of the 14{sup th} German Atomic Energy Law Symposium featured a broad spectrum of topics ranging from backfitting of nuclear power plants to European atomic energy and radiation protection law, to challenges facing national legal systems in the execution of atomic energy law, to legal issues connected with decommissioning and waste management, and on to the topical subject of finding a repository site. The 14{sup th} German Atomic Energy Law Symposium, on the whole, again demonstrated that an open discourse between science and practice is able to furnish important contributions to the implementation of laws in a balanced way rooted in practice. Especially the contributions dealing with the independence of public authorities and their organization, the doctrine of the reservation of functions of the executive branch, and planning by laws contain additional provisions able to influence the continued development of administrative law also above and beyond atomic energy law. The BMU also referred to a decision just heard from Brussels to the effect that a new European Safety Directive would be published as early as in 2013. As a consequence of the nuclear stress tests conducted EU-wide, the Directive is to lay down provisions about

    With introduction of a diagnosis-related groups system (DRG-system) in Germany the previous duration of stay based refunding is also replaced for the radioiodine therapies by a performance oriented reimbursement system. Since the at first optional start of the DRG-system in 2003 the adaptations which take place every year should lead, up to the planned end of the convergence phase in 2009, to a transparent, fair and economical financing system of the stationary hospital service. The physician is responsible for the right and complete coding of the diagnoses and procedures, which serve as essential parameters for the determination of the diagnosis related group (DRG) of a hospital case. In the actual version of the year 2005 the DRG-system still supplies for radioiodine therapy of thyroid carcinoma some unclarity in the coding of the diagnosis, as well as clear inadequacy with the fair mapping of the therapy costs.

    2002-01-01

    The Chernobyl accident led to a widespread contamination of the environment in most European countries. In Germany, like in all other countries, it took some time to evaluate the radiological situation, time which is extremely valuable in the early phases of an accident when decisions on countermeasures like sheltering, iodine prophylaxis or evacuation have to be taken. For a better emergency preparedness the Integrated Information and Measurement System (IMIS) has been developed and established in Germany. In case of a widespread contamination of the environment, the system will provide the decision makers with all information necessary to evaluate the radiological situation and to decide on countermeasures. Presently this system is upgraded due to the adoption of the European decision supporting system RODOS and by the improvement of the national information exchange. For this purpose the web based information system ELAN has been developed. The national systems have to be integrated into the European and international communication systems. In this presentation the IMIS system is briefly described and the new features and modules of the system are discussed in greater detail

    The Living Systems Energy Module, renamed Voyage from the Sun, is a twenty-lesson curriculum designed to introduce students to the major ways in which energy is important in living systems. Voyage from the Sun tells the story of energy, describing its solar origins, how it is incorporated into living terrestrial systems through photosynthesis, how it flows from plants to herbivorous animals, and from herbivores to carnivores. A significant part of the unit is devoted to examining how humans use energy, and how human impact on natural habitats affects ecosystems. As students proceed through the unit, they read chapters of Voyage from the Sun, a comic book that describes the flow of energy in story form (Appendix A). During the course of the unit, an ``Energy Pyramid`` is erected in the classroom. This three-dimensional structure serves as a classroom exhibit, reminding students daily of the importance of energy and of the fragile nature of our living planet. Interactive activities teach students about adaptations that allow plants and animals to acquire, to use and to conserve energy. A complete list of curricular materials and copies of all activity sheets appear in Appendix B.

    The Coventry (Lanchester) Polytechnic Wave Energy Group has been involved in the United Kingdom wave energy research programme since its inception in 1975. Whilst the work of the group is mainly concerned with wave energy, and currently is directed towards the design of a wave energy device tailored to the needs of isolated/island communities, it has some involvement with other aspects of the alternatives. This conference, dealing with alternative energy systems and their electrical integration and utilisation was engendered by the general interest which the Polytechnic group members have in the alternatives and their use. The scope for electrical integration and utilisation is very broad. Energy for family groups may be provided in a relatively unsophisticated way which is acceptable to them. Small population centres, for example island communities relying upon diesel equipment, can reap the benefits of the alternatives through their ability to accept novel integration schemes and a flexible approach to the use of the energy available. Consumers already enjoying the benefits of a 'firm' electricity grid supply can use energy from a variety of alternative systems, via the grid, without having to modify their energy consumption habits. In addition to the domestic and industrial applications and coastal possibilities, specialist applications in isolated environments have also emerged. The Proceedings detail practical, technical and economic aspects of the alternatives and their electrical integration and utilisation.

In spite of the large quantity of lectures and following the tradition of our former events, the conference will again last only two days, offering a chance to all those who have difficulties to find the time to inform themselves about the latest technical and scientific developments and experience in the field of wind energy. The fast-growing world-wide application of wind energy with the resulting new challenges for technology and operation leads us more than ever to place particular emphasis on the combination of theory and application of wind energy when defining the main technical and scientific topics of the conference. With a total number of 109 proposals for lectures, 27 of which are in English, from 17 different countries, DEWEK 2000 already met with a very favourable response. For the first time there will be a German-English simultaneous translation during the conference, to allow participants from foreign countries to follow the lectures. The exceptionally high quality of the papers proposed made it extremely difficult for us this time to make the necessary distinction between lecture and poster contributions. To an extent that we never reached before, the papers deal with very concrete aspects of the application of wind energy, and thus reflect the operating conditions varying from site to site of a new energy technology spreading rapidly all over the world.

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

    IMIS is being set up as part of the German Government's National Response Plan for dealing with the consequences of a large scale radioactive contamination of the environment. The IMIS system has three operational action levels. Level 3 covers the collection of radiological data from state-of-the-art monitoring networks and measurement laboratories. Level 2 involves computerised data processing and quality control, based on standardised procedures for the collection and presentation of measurements. This level also includes the use of transport and dose assessment models. Level 1 includes evaluation of the data, management of the consequences of a given situation, legal enforcement of protective measures and provision of information to the public. In its final form the IMIS system will consist of a total of 75 RISC computers linked together by an efficient packet-switched Wide Area Network. Owing to various demands of the individual users, three different types of RISC computers are used. The system software includes ULTRIX, TCP/IP and X windows. The relational database management system ORACLE is used together with the query language SQL-Plus. Statistical analyses are carried out with the standard product SAS. The geographical information system TERRA provides all the tools necessary for a detailed geographic presentation of the data. (author)

    Orthopedics and trauma surgery are subject to continuous medical advancement. The correct and performance-based case allocation by German diagnosis-related groups (G-DRG) is a major challenge. This article analyzes and assesses current developments in orthopedics and trauma surgery in the areas of coding of diagnoses and medical procedures and the development of the 2012 G-DRG system. The relevant diagnoses, medical procedures and G-DRGs in the versions 2011 and 2012 were analyzed based on the publications of the German DRG Institute (InEK) and the German Institute of Medical Documentation and Information (DIMDI). Changes were made for the International Classification of Diseases (ICD) coding of complex cases with medical complications, the procedure coding for spinal surgery and for hand and foot surgery. The G-DRG structures were modified for endoprosthetic surgery on ankle, shoulder and elbow joints. The definition of modular structured endoprostheses was clarified. The G-DRG system for orthopedic and trauma surgery appears to be largely consolidated. The current phase of the evolution of the G-DRG system is primarily aimed at developing most exact descriptions and definitions of the content and mutual delimitation of operation and procedures coding (OPS). This is an essential prerequisite for a correct and performance-based case allocation in the G-DRG system.

    The ATLAS tier centers in Germany provide their computing resources for the ATLAS experiment. The stable and sustainable operation of this so-called DE-cloud heavily relies on effective monitoring of the Tier-1 center GridKa and its associated Tier-2 centers. Central and local grid information services constantly collect and publish the status information from many computing resources and sites. The cloud monitoring system discussed in this presentation evaluates the information related to different cloud resources and provides a coherent and comprehensive view of the cloud. The main monitoring areas covered by the tool are data transfers, cloud software installation, site batch systems, Service Availability Monitoring (SAM). The cloud monitoring system consists of an Apache-based Python application, which retrieves the information and publishes it on the generated HTML web page. This results in an easy-to-use web interface for the limited number of sites in the cloud with fast and efficient access to the required information starting from a high level summary for the whole cloud to detailed diagnostics for the single site services. This approach provides the efficient identification of correlated site problems and simplifies the administration on both cloud and site level.

    This article argues that two core domains of the German coordinated market economy have undergone transformative institutional change: the welfare state and the vocational training system. We argue that this process is best described as a process of liberalization resulting from the exhaustion of traditional institutions. Exhaustion describes a mechanism of institutional change in which endogenous negative feedback effects, caused by the overextension of resources, lead to a transformation of...

  12. Determination of cost–potential-curves for wind energy in the German federal state of Baden-Württemberg

    International Nuclear Information System (INIS)

    McKenna, R.; Gantenbein, S.; Fichtner, W.

    2013-01-01

    The new federal government in the German federal state of Baden-Württemberg has set a target for 10% of gross electricity generation from wind energy by 2020. Given that currently around 0.1% of the electricity generation comes from wind energy, this paper examines the technical feasibility and economic costs associated with realising this goal. The technical potential for wind energy in Baden-Württemberg is determined, along with the costs of electricity generation, which together lead to the derivation of cost–potential-curves. The technical potential is calculated by identifying the available area with the aid of a geographical information system (GIS) and land use information. With the help of a regional wind atlas, turbine power curves and an assumed wind speed frequency distribution, the spatially distributed electricity generation potential on a district level is estimated. The costs of wind energy are investigated for the year 2010 and projected for the years 2020 and 2030 on the basis of learning curves. The result is a suitable area for wind energy of 2119 km², which amounts to 5.9% of the total area of Baden-Württemberg. Depending on the wind turbine selected, a capacity of 18.5 GW up to 24.5 GW could be installed and depending on the hub height and the turbine, an electricity yield of 29.3 TWh up to 40.7 TWh could be generated. The costs of electricity, depending on the type of turbine and the average wind speed, but lie for 2010 between 3.99 and 21.42 €-cents/kWh, reducing by 2030 to 3.33–17.84 €-cents/kWh. - Highlights: ► Baden-Württemberg has a goal of 10% of electricity from wind energy by 2020. ► This is examined with cost–potential curves on district level. ► The result is a suitable area for wind energy of 2119 km². ► A capacity of 19–25 GW or an electricity yield of 29–41 TWh could be generated. ► The costs of electricity lie for 2010 between 3.99 and 21.42 €-cents/kWh

  13. Which goals are driving the Energiewende? Making sense of the German Energy Transformation

    In 2010, Germany agreed a plan to increase the share of renewables in power consumption to 80% by 2050, and in 2011 the decision was taken to phase-out nuclear power by 2022. This policy is now widely known as the “Energiewende”. While many global observers consider this program to be primarily driven by the need to tackle climate change, the precise political goals of the Energiewende are, by and large, unclear. In our study we compiled a list of 14 goals put forward in political debates and conducted a “mapping” survey among more than 50 policy experts. We asked them to prioritize the goals based on their personal views and provide arguments for their rankings in ensuing interviews. Our main findings are as follows: (i) a large majority named climate protection among the top-level goals of the Energiewende; at the same time, around 80% of all participants also identified additional goals; (ii) when asked if the Energiewende would make sense even if climate change did not exist, two thirds of the participants agreed, which, when taken with the first finding, demonstrates that the goals and motivations driving the Energiewende are more complex than often assumed. We conclude that for the sake of effective and efficient policies and ever rising climate policy ambition, a public debate and clear specification of the top-level goals are indispensable. - Highlights: •We examine the goals of German energy policy called the “Energiewende”. •We show that policy experts relate up to 14 goals with the Energiewende. •So far the political goals of the Energiewende, and especially their ranking is unclear. •We call for a public debate and a clear specification of the top-level goals of the Energiewende.

    This thesis presents scenarios of future energy systems, a cost-benefit analysis of measures to avoid greenhouse-gas emissions, an analysis of the effect of energy prices on end-use efficiencies and fuel choices, and an evaluation of financial-incentive programs designed to induce investments in efficient energy use. Twelve integrated energy supply/demand scenarios for the Swedish heat-and-power sector are presented to illustrate the potential for improvements in end-use efficiency and increased utilization of renewable energy sources. The results show that greenhouse-gas emissions could be reduced by 35 per cent from 1987 levels by 2010, with a net economic benefit compared to a business-as-usual scenario. A generalized methodology for calculating the net costs of reducing greenhouse-gas emissions is applied to a variety of fuel choices and energy end-use technologies. A key finding is that a combination of increased end-use efficiencies and use of renewable energy systems is required to achieve maximum cost-effective emissions reductions. End-use efficiencies and inter-fuel competition in Denmark and Sweden are compared during a time period in which real electricity prices were declining in Sweden and increasing in Denmark. Despite these different price environments, efficiencies and choices of heating fuels did not generally develop as expected according to economic theory. The influences of counter-price and non-price factors are important in understanding this outcome. Relying on prices alone injects considerable uncertainty into the energy planning process, and precludes efficiency improvements and fuel choices attainable with other mechanisms. Incentive programs can be used to promote energy-efficient technologies. Utilities in Europe have recently offered financial incentives intended to stimulate the adoption of compact-fluorescent lamps. These programs have been cost-effective in comparison to new electric supply. (au).

    The EU project Weather Impacts on Natural, Social and Economic Systems (WISE) has analysed impacts of current climate variability to evaluate the sensitivity of today's society to extreme weather. Unlike studies of anticipated impacts of climate change, WISE did not rely on scenarios and projections, but on existing and newly collected data. The research involved (i) the statistical modelling of meteorological and sectoral time series, aimed at quantifying the impacts of changing weather variables on sector output, (ii) a population survey, aimed at investigating public perception of and behavioural response to unusually hot and dry summers and mild winters, and (iii) a management survey, aimed at obtaining insight into managers' awareness and perception of the importance of extreme weather on their operations. The three activities revealed a wealth of data and information, providing relevant insights into Germany's sensitivity to and perception of extreme weather events. Sectors that were analysed included agriculture, outdoor fire, water supply, human health, electricity and gas consumption and tourism. It appears from the statistical modelling that extreme weather can have impressive impacts on all sectors, especially when expressed in monetary terms. However, weather variability is generally considered a manageable risk, to which sectors in Germany appear reasonably well-adapted. The population and management surveys reveal both positive and negative impacts of extreme weather. People generally respond to these impacts by adjusting their activities. The utilities (electricity, gas and water) indicate that they are robsut to the current level of weather variability and do not consider climate change an important threat to their operations. The tourism sector experiences impacts but typically takes a reactive approach to adaptation, although it is also developing weather-insensitive products. (orig.)

    The development of a centralised and sustainable heat supply through the construction of heat grids offers consumers numerous advantages compared to a decentralised energy supply of residential and commercial properties. Where the migration to centralised heat supply relegates fossil fuels through the long-term incorporation of sustainable renewable energy sources, the projects make an important contribution towards meeting the government's climate protection goals. Heat generation and heat sales from renewable energy sources should be ensured in the long term. In the countryside, biogas plant operators are frequently the initiators of heat grid investments, or they take on the role of supplier for the provision of low-cost CHP heat from cogeneration units. In view of the limited remuneration period under the terms of the German Renewable Energy Act, the clock is ticking for the establishment of a centralised heat supply. This paper presents the advantages and disadvantages of a centralised, sustainable heat supply and additionally considers the flexibi/isation of biogas plants in view of the construction of the heat grid and the associated infrastructure. A focus is placed on the security of supply for customers after the discontinuation of remuneration under the German Renewable Energy Act and on how a competitive heat price from alternative energy sources can continue to be ensured.

WWith the first ''Social sustainability barometer of the energy transition'', published in November 2017, the IASS presents a monitoring instrument with a comprehensive, empirically sustainable database on the social dimensions of energy turnaround: it records annually the attitudes, justice sensations, experiences and expectations of different population groups in Germany with regard to the energy transition and identifies social challenges and political needs for action.

    Full text: Nuclear safety experts concluded a seven-day mission to review the German Regulatory System, conducted from 4-10 September in Bonn, Stuttgart and Berlin. At the request of the Government of the Federal Republic of Germany, the International Atomic Energy Agency assembled a peer-review team of six high-level regulatory experts from six nations (Finland, France, the Netherlands, Switzerland, the UK, the US and three IAEA senior staff members) to conduct a follow-up assessment of an Integrated Regulatory Review Service (IRRS) mission conducted in 2008. This follow-up IRRS mission examined the progress in acting upon the recommendations and suggestions made during the 2008 IRRS mission and reviewed the areas of significant regulatory changes since that review at both the Federal Ministry of Environment, Nature Conservation and Nuclear Safety (BMU) and the Ministry of Environment of the federal state of Baden-Wurttemberg (UM BW). The first mission reviewed Germany's regulatory framework against IAEA Safety Standards and fostered the exchange of information and experience on safety regulation. This is a peer review based on IAEA Standards. It is not an inspection, nor an audit. The scope of the mission was limited to the safety regulation of nuclear power plants. IRRS team leader, Mr. McCree, of the US Nuclear Safety Commission (USNRC), said, ''This was an important IRRS mission, particularly given the recent Fukushima Daiichi Nuclear Power Plant accident and the related insights which underscore the importance of having an independent, credible nuclear safety regulator.'' ''The IRRS team identified several strengths of the German nuclear safety regulators, including the prompt and coordinated incident response activities of BMU and UM BW to the Fukushima accident. Some suggestions were also made to further strengthen nuclear safety regulations concerning the future work of BMU,'' he said. The review team found that important progress has been made toward

    The contemporary industrial metabolism is not sustainable. Critical problems arise at both the input and the output side of the complex: Although affordable fossil fuels and mineral resources are declining, the waste products of the current production and consumption schemes (especially CO(2) emissions, particulate air pollution, and radioactive residua) cause increasing environmental and social costs. Most challenges are associated with the incumbent energy economy that is unlikely to subsist. However, the crucial question is whether a swift transition to its sustainable alternative, based on renewable sources, can be achieved. The answer requires a deep analysis of the structural conditions responsible for the rigidity of the fossil-nuclear energy system. We argue that the resilience of the fossil-nuclear energy system results mainly from a dynamic lock-in pattern known in operations research as the "Success to the Successful" mode. The present way of generating, distributing, and consuming energy--the largest business on Earth--expands through a combination of factors such as the longevity of pertinent infrastructure, the information technology revolution, the growth of the global population, and even the recent financial crises: Renewable-energy industries evidently suffer more than the conventional-energy industries under recession conditions. Our study tries to elucidate the archetypical traits of the lock-in pattern and to assess the respective importance of the factors involved. In particular, we identify modern corporate law as a crucial system element that thus far has been largely ignored. Our analysis indicates that the rigidity of the existing energy economy would be reduced considerably by the assignment of unlimited liabilities to the shareholders.

    Full text: An international expert team has today completed a two-week IAEA review of Germany's nuclear regulatory system. The team identified good practices within the system and gave advice on some areas for further improvement. The IAEA has conveyed the initial findings to German authorities but the final report will be submitted within two months. At the request of the Government of the Federal Republic of Germany, the International Atomic Energy Agency (IAEA) assembled a team of 14 experts to conduct an Integrated Regulatory Review Service (IRRS) mission. This is a peer review based on IAEA Standards. It is not an inspection, nor an audit. The scope of the mission was limited to the safety regulation of nuclear power plants. Experts from Canada, the Czech Republic, Finland, France, Japan, the Netherlands, Republic of Korea, Spain, Switzerland, the UK, the US and from the IAEA took part in the mission, which was conducted from 7 to 19 September in Bonn, Stuttgart and Berlin. The main basis for the review was a well-prepared self-assessment made by the Federal Ministry of Environment, Nature Conservation and Nuclear Safety (BMU) and the Ministry of Environment of the federal state of Baden-Wuerttemberg (UM BW). 'The team members were impressed by the extensive preparation and dedication of the staff both at BMU and UM BW to excellence in nuclear safety,' said Mike Weightman, IRRS Team Leader and Chief Inspector of the UK nuclear regulatory body, the Nuclear Directorate of the Health and Safety Executive. 'We hope the IRRS mission will facilitate further improvements in the safety regulation of nuclear power in Germany and throughout the world.' 'Germany's invitation to undergo such a detailed review is a clear demonstration of its openness and commitment to continuously improve nuclear safety regulation,' said Philippe Jamet, Director of the IAEA's Nuclear Installation Safety Division.

    A new GeO2-Ga2O3-Na2O-BaO-La2O3 germanate glass doped with Ho2O3, Tm2O3, and Er2O3 has been investigated for application as a laser material at the 2 μm region. The spectroscopic properties and energy transfer mechanisms of Ho3+ sensitized by Tm3+ and Er3+ are analyzed. Based on the measurement of absorption spectra, the Judd-Ofelt intensity parameters, radiation emission probability, branching ratio, and lifetime of Ho3+ are calculated to evaluate the spectroscopic properties. The maximum value of emission cross section of Ho3+ around 2.05 μm is 8.003×10-21 cm2, which indicates that the germanate glass may provide high gain as a good medium in high-power level laser system. It is also found that the 2.05 μm emission of Ho3+:5I7→5I8 can be greatly enhanced by adding the proper amount of Er2O3 and Tm2O3 under excitation at 808 nm. With the large energy transfer coefficient, the high efficient energy transfer process among Ho3+, Tm3+, and Er3+ ions is proven.

    Intensive care medicine is extremely heterogeneous, expensive and can only be partially planned and controlled. A correct and fair representation of intensive care medicine in the G-DRG system is an essential requirement for the use as a pricing system. From the perspective of intensive care medicine, pertinent changes of the DRG structure and differentiation of relevant parameters have been established within the G-DRG systems 2003-2010. Analysis of relevant diagnoses, medical procedures, co-payment structures and G-DRGs in the versions 2003-2010 based on the publications of the German DRG Institute (InEK) and the German Institute of Medical Documentation and Information (DIMDI). Since the first G-DRG system version 2003, numerous measures improved quality of case allocation of intensive care medicine. Highly relevant to the system version 2010 are duration of mechanical ventilation, the intensive care treatment complex and complicating constellations. The number of G-DRGs relevant to intensive medical care increased from n = 3 (2003) to n = 58 (2010). For standard cases, quality of case allocation and G-DRG reimbursement are adequate in 2010. The G-DRG system gained complexity again. High demands are made on correct and complete coding of complex cases. Nevertheless, further adjustments of the G-DRG system especially for cases with extremely high costs are necessary. Where the G-DRG system is unable to cover extremely high-cost cases, reimbursement solutions beyond the G-DRG structure should be taken into account.

    German governments throughout the last 25 years have accepted the sustainability paradigm und put forth an energy policy that supports the development of renewable energies, the reduction of greenhouse gas emissions and the improvement of energy efficiency. Together with the process of seeking to phase out nuclear power, these objectives constitute the ‘Energiewende’ (energy transition) the Energiewende has reached a level that reveals its challenges and thus makes it a valuable case study. Based on a multi-method stakeholder analysis, frequently debated controversial issues related to the Energiewende have been identified and will be confronted with “reality” in this paper. The set of controversial issues includes the following five aspects: security of electricity supply, rising electricity prices for industry and commerce, rising electricity prices for consumers, impacts of the energy transition on employment, and the effects of the politically instigated speed of the Energiewende on its practical implementation.

    The decision to raise the levy imposed by the Renewable Energies Law has kindled the discussion as to how the energy turnaround can best be implemented and made affordable in the first place. The search for solutions should be founded on as full a picture of the situation as possible as well as a fact base shared by all. The aspiration and purpose of the German 2020 Energy Turnaround Index created by McKinsey and Company is to create precisely such a fact base. Every 3 months the index gives an update on the status of the energy turnaround based on 15 indicators. The present update additionally takes a closer look at the aspect of economic efficiency, which together with climate and environment protection and security of supply forms the triad of imperatives driving the energy turnaround.

    A power system for connecting a variable voltage power source, such as a power controller, with a plurality of energy storage devices, at least two of which have a different initial voltage than the output voltage of the variable voltage power source. The power system includes a controller that increases the output voltage of the variable voltage power source. When such output voltage is substantially equal to the initial voltage of a first one of the energy storage devices, the controller sends a signal that causes a switch to connect the variable voltage power source with the first one of the energy storage devices. The controller then causes the output voltage of the variable voltage power source to continue increasing. When the output voltage is substantially equal to the initial voltage of a second one of the energy storage devices, the controller sends a signal that causes a switch to connect the variable voltage power source with the second one of the energy storage devices.

    The German diagnosis-related Group (G-DRG) System has recently been published in its third version. From 2005 on, this system will be the definite measure for the budgets of nearly all german hospitals. The preliminary phase with no budget reduction or redistribution being made and in which an inappropriate classification system had no negative impact on reimbursement has, thus, come to an end. At present, many hospitals are struggling in an economic competition about the independence or maintenance of the hospital or several sub-departments. The changes in the classification system with regard to a marked increase in the number of G DRGs, a modified grouping-logic, more properly determined reductions and extra charges for low and high outlier as well as the introduction of further additional charges contribute thereby to a better covering of services and treatments of cardiovascular patients. However, while many of the known problems have been eliminated, there are still weaknesses in the G-DRG System even concerning cardiovascular medicine. The G-DRG System has to be adapted continuously with consultation of the clinical expertise of the respective medical societies. The most important new aspects and changes in the G-DRG System 2005 and the accompanied execution regulations are explained with special view on cardiology.

    2013-03-01

    The purpose of this paper is to develop ways to improve patient-level cost apportioning (PLCA) in the English and German inpatient 'DRG' cost accounting systems, to support regulators in improving costing schemes, and to give clinicians and hospital management sophisticated tools to measure and link their management. The paper analyzes and evaluates the PLCA step in the cost accounting schemes of both countries according to the impact on the key aspects of DRG introduction: transparency and efficiency. The goal is to generate a best available PLCA standard with enhanced accuracy and managerial relevance, the main requirements of cost accounting. A best available PLCA standard in 'DRG' cost accounting uses: (1) the cost-matrix from the German system; (2) a third axis in this matrix, representing service-lines or clinical pathways; (3) a scoring system for key cost drivers with the long-term objective of time-driven activity-based costing and (4) a point of delivery separation. Both systems have elements that the other system can learn from. By combining their strengths, regulators are supported in enhancing PLCA systems, improving the accuracy of national reimbursement and the managerial relevance of inpatient cost accounting systems, in order to reduce costs in health care.

    One fundamental challenge of the German energy transition for the electricity market is the growing imbalance between inflexible generation and generally inelastic load. Against this background, we investigate the future potential of decentralized Power-to-Heat (P2H) as an additional demand-side flexibility option for the German electricity system. Precisely, we analyze the case of hybrid systems, where conventional gas and oil condensing boiler systems are equipped with an electric heating rod. In contrast to previous approaches, we set our focus on the economic incentives at household level: only if the switch to a P2H-hybrid system can reduce individual heating expenses significantly, a considerable number of these systems will be installed. For this purpose, we implemented an integrated approach combining three distinct simulation modules. First, a stochastic simulation of the electricity spot market prices in 2020 was conducted. Second, average heat load profiles were generated based on a standard bottom-up analysis. Both results were then fed into an optimization model calculating the cost-minimizing paths of heat generation at household level during the year 2020. The simulated annual savings prove modest as long as household electricity prices are not heavily reduced through political influence. - Highlights: • We investigate the future potential of decentralized Power-to-Heat. • Focus lies on hybrid Power-to-Heat systems with condensing gas or oil boiler. • We analyze the economic incentives at household level. • Simulation of heat load profiles and spot prices in 2020. • Savings prove modest as long as household electricity prices are not heavily reduced.

    On the basis of distubances which actually have occurred in German nuclear power plants a case-study has been performed to evaluate the feasibility of the computer-based disturbance analysis system STAR. By means of a compact plant simulator the disturbances collected have been remodelled and anlysed, on-line, with the disturbance analysis system STAR. In the last phase of the project experiments have been performed with reactor operators to get their reaction to, and opinion on, computerbased-operator aids. (orig.) [de

    Diagnosis-related groups (DRGs) are a patient classification system grouping related types of patients treated to the resources they consumed. In this analysis we compared the Italian and the German DRG systems regarding hand surgery with an emphasis on reimbursement of clinical cases. The 15 most common hand surgical diagnoses and their corresponding operative treatment in our clinic in 2009 were processed using a DRG grouper. The underlying data were transferred to the Italian system. Thus, the length of stay and the reimbursement of both countries could be obtained and compared. The latter was adjusted and corrected by the purchasing power of each country. The mean of the upper threshold of length of stay was 10 days in the German as well as the Italian system whereas the median was 2 times higher in Italy (6 vs. 12 days). Fifteen out of 19 cases showed higher reimbursement in Germany. The case mix index (CMI) of 0.917 in Germany represents a mean payment of 2,676 € per case. In Italy the hypothetical CMI of 0.635 resulted in a mean reimbursement of 1,853 € per case. The biggest difference in remuneration could be found for replantation of multiple fingers. For this service the German health-care system pays 12,320 € more than the Italian. Total proceeds of the top 15 diagnoses applying the number of cases treated in our clinic revealed 1.7 million € in the German and 1.2 million € in the Italian DRG system. Considering the purchasing power utilizing consumer prize parities, the difference of reimbursement between the countries decreased to 300,000 €. There is no mean length of stay per DRG in Italy, only the upper threshold of length of stay is determined. In most cases the latter is higher in Italy compared to Germany. The consumption of resources for finger replantation is not adequately represented in the Italian DRG system compared to finger amputation. Reimbursement of inpatient care is influenced by multiple factors not being subject

    Wellons Canada is a British Columbia-based company that specializes in the manufacture and installation of lumber drying and energy conversion equipment. This brochure provided details of the Wellons energy system designed for oriented strand board (OSB) plants. The brochure outlined the system's scope of supply, and provided illustrations of system procedures from the initial wet fuel bin through to the electric precipitator used for air clean-up. During the process, fuel was conveyed from the bin to metering bins into combustors and through a cyclo-blast cell. Forced draft fan systems were then used to provide primary and secondary combustion air. Radiant heaters were then used. A drop-out chamber was supplied to allow for complete combustion of fuel particles and to provide a drop-out of ash. A fan was then used to deliver diluent air to maintain the set point temperature in the hot gas stream. Refractory lined hot gas ducts were used to deliver heat to the dryers. Hot gas was then drawn through a multi-cyclone collector for ash removal. Electrostatic precipitators were used to clean up emissions on a continuous operating basis. An automatic system was used to collect ash from the combustion system grates and other areas. Details of installation services provided by the company were also included. 42 figs.

    Prediction is very difficult, especially if it's about the future. This witticism, which has been alternatively ascribed to Mark Twain, Karl Valentin, Niels Bohr and Winston Churchill, could hardly be truer than when applied to the wind and sun, especially in the case of long-term forecasts. Wind power and photovoltaic plant capacities are what needs to grow most if renewable energies really are to cover 80% of Germany's energy supply by the year 2050. Other renewable energy resources do not have the potential to contribute substantially to achieving the goals proclaimed by the German federal government. Some 64% of electricity production and 70% of installed power capacity will be coming from the wind and sun in the year 2050, according to recent calculations. A study prepared by Prognos AG on behalf of the German National Committee of the World Energy Council has investigated the question as to what extent international hydropower storages are capable of taking up surplus electricity and holding it available as a power reserve.

    In February 2000, the German Bundestag established a Study Commission on 'Sustainable Energy Supplies in View of Globalisation and Liberalisation' (cf. Final Report, 2002). The Commission's Final Report is a contribution made by Germany toward implementing the sustainable development objectives defined in 1992 at the World Summit in Rio de Janeiro (Agenda 21). Despite minority votes of several members of the Study Commission, the main outcomes of the Final Report are worthwhile discussing in other industrial countries. The Commission had been given the mandate to identify 'robust, sustainable development paths' for the energy sector for the period up to 2050, which represent a scientific basis for the German parliament's further decision-making in the field of long-term energy policy. The applied backcasting approach showed that an ambitious climate-protection goal--reducing CO 2 emissions by 80% by 2050 - is technically and economically feasible. The main strategies and instruments for protecting the climate while ensuring a sustainable energy supply are summarised

    The wind energy conversion system includes a wind machine having a propeller connected to a generator of electric power, the propeller rotating the generator in response to force of an incident wind. The generator converts the power of the wind to electric power for use by an electric load. Circuitry for varying the duty factor of the generator output power is connected between the generator and the load to thereby alter a loading of the generator and the propeller by the electric load. Wind speed is sensed electro-optically to provide data of wind speed upwind of the propeller, to thereby permit tip speed ratio circuitry to operate the power control circuitry and thereby optimize the tip speed ratio by varying the loading of the propeller. Accordingly, the efficiency of the wind energy conversion system is maximized.

    The present book provides an overview of the energy market of the German Federal Republic. Its main emphasis is on structures of demand and supply in the markets for crude oil, brown coal, hard coal, natural gas and electricity. A special chapter has been dedicated to renewable energy resources. Another focal area are the price formation mechanisms for oil, coal, natural gas and electricity. The development of energy demand is analysed, differentiating between the sectors industry, transport, households and trade/industry/services. The book addresses the international climate protection treaties, the legal framework for climate protection activities at the European level and the implementation of trade in greenhouse gas emission permits in Germany. It presents current forecasts and scenarios, thus pointing out possible perspectives in the German energy market. It also discusses the framework conditions for Germany's energy policy. The energy markets are portrayed through facts and figures compiled in a total of 125 tables and 148 diagrams. Details of ownership of more than 100 utility companies are made transparent. The chapter on energy in the coalition agreement of 27 November 2013 between the Christian Democratic Union, Christian Social Union and the Social Democratic Party is documented verbatim. Rounding off the publication is a detailed glossary that will facilitate the reader's understanding of complex matters in the field of energy economy.

    Fossil fuels (i.e., petroleum, natural gas and coal), which meet most of the world's energy demand today, are being depleted fast. Also, their combustion products are causing the global problems, such as the greenhouse effect, ozone layer depletion, acid rains and pollution, which are posing great danger for our environment and eventually for the life in our planet. Many engineers and scientists agree that the solution to these global problems would be to replace the existing fossil fuel system by the hydrogen energy system. Hydrogen is a very efficient and clean fuel. Its combustion will produce no greenhouse gases, no ozone layer depleting chemicals, little or no acid rain ingredients and pollution. Hydrogen, produced from renewable energy (e.g., solar) sources, would result in a permanent energy system, which we would never have to change. However, there are other energy systems proposed for the post-petroleum era, such as a synthetic fossil fuel system. In this system, synthetic gasoline and synthetic natural gas will be produced using abundant deposits of coal. In a way, this will ensure the continuation of the present fossil fuel system. The two possible energy systems for the post-fossil fuel era (i.e., the solar-hydrogen energy system and the synthetic fossil fuel system) are compared with the present fossil fuel system by taking into consideration production costs, environmental damages and utilization efficiencies. The results indicate that the solar-hydrogen energy system is the best energy system to ascertain a sustainable future, and it should replace the fossil fuel system before the end of the 21st century

    For several years, researchers at Princeton University`s Center for Energy and Environmental Studies have carried out technical and economic assessments of hydrogen energy systems. Initially, we focussed on the long term potential of renewable hydrogen. More recently we have explored how a transition to renewable hydrogen might begin. The goal of our current work is to identify promising strategies leading from near term hydrogen markets and technologies toward eventual large scale use of renewable hydrogen as an energy carrier. Our approach has been to assess the entire hydrogen energy system from production through end-use considering technical performance, economics, infrastructure and environmental issues. This work is part of the systems analysis activity of the DOE Hydrogen Program. In this paper we first summarize the results of three tasks which were completed during the past year under NREL Contract No. XR-11265-2: in Task 1, we carried out assessments of near term options for supplying hydrogen transportation fuel from natural gas; in Task 2, we assessed the feasibility of using the existing natural gas system with hydrogen and hydrogen blends; and in Task 3, we carried out a study of PEM fuel cells for residential cogeneration applications, a market which might have less stringent cost requirements than transportation. We then give preliminary results for two other tasks which are ongoing under DOE Contract No. DE-FG04-94AL85803: In Task 1 we are assessing the technical options for low cost small scale production of hydrogen from natural gas, considering (a) steam reforming, (b) partial oxidation and (c) autothermal reforming, and in Task 2 we are assessing potential markets for hydrogen in Southern California.

    Severely injured patients represent a relevant financial cost factor in the health system especially for high level trauma centres. The introduction of a"diagnosis-related group" (DRG) system in Germany further revealed the potential negative economic impact of severely injured patients for trauma centres. In recent years several changes of the specific DRG for severely injured patients occurred with the aim of a convenient reimbursement for the trauma patient. The present study analysed 38 multiply injured patients admitted in the first half of the year 2004. These patients were analysed in terms of the respective DRG that was attributed to the patient on the basis of the definition criteria for 2004 and 2005. In addition for the same patient group the total inpatient treatment costs were calculated according to the algorithm developed by the Working Group on Polytrauma of the German Trauma Society. The analysis revealed three major problems in the reimbursement for severely injured patients according to the German DRG system: (1) In spite of the additional payment for blood compounds on top of the DRG reimbursement in 2005 a mean economic deficit of more than 4000 euro remains for each severely injured patient. (2) In 30% of the analysed trauma patients the combination of the diagnosis and operations did not lead to a specific polytrauma DRG or to an intensive care medicine DRG. (3) In the patients that could not be attributed to a polytrauma DRG, the economic deficit was with an average of more than 9000 euro even higher. This attribution aspect is also currently relevant, since the definition criteria for a polytrauma DRG were not changed in 2006 or 2007. We conclude that besides the recent changes in the reimbursement for polytrauma DRGs, which have been at least partly adapted to the real financial burden of these patients, the definition of a severely injured patient in the German DRG system may also need to be revised.

    Diagnosis-Related Groups (DRG) are a patient classification system grouping related types of patients treated to the resources they consumed. In this analysis, we compared the Austrian and the German DRG systems. The 15 most common hand surgical diagnoses and their corresponding operative treatment were transferred into the Austrian system. Thus, the length of stay and the reimbursement of both countries could be obtained and compared. The mean values and the median values of the upper and lower thresholds of length of stay as well as the average length of stay were all lower in Austria compared to Germany. Reimbursement in Germany was higher in 13 of 19 cases. Total proceeds amounted to 1.67 million in the German and 1.70 million in the Austrian health care system. Considering the purchasing power applying consumer prize parities, the difference of reimbursement between the countries rose to 130,000 which equals a difference of almost 8%. Reimbursement of the top 15 diagnoses in hand surgery in Austria is 8% higher than in Germany. Except for one case, mean values as well as upper and lower thresholds of length of stay are considerably shorter in Austria. Comparison of international data to refine a national compensation system is advocated.

    Critically injured patients are a very heterogeneous group, medically and economically. Their treatment is a major challenge for both the medical care and the appropriate financial reimbursement. Systematic underfunding can have a significant impact on the quality of patient care. In 2009 the German Trauma Society and the DRG-Research Group of the University Hospital Muenster initialised a DRG evaluation project to analyse the validity of case allocation of critically injured patients within the German DRG system versions 2008 and 2011 with additional consideration of clinical data from the trauma registry of the German Trauma Society. Severe deficits within the G-DRG structure were identified and specific solutions were designed and realised. A retrospective analysis was undertaken of standardised G-DRG data (§ 21 KHEntgG) including case-related cost data from 3 362 critically injured patients in the periods 2007 and 2008 from 10 university hospitals and 7 large municipal hospitals. For 1 241 cases of the sample, complementary detailed information was available from the trauma registry of the German Trauma Society to monitor the case allocation of critically injured patients within the G-DRG system. Analyses of coding and grouping, performance of case allocation, and the homogeneity of costs in the G-DRG versions 2008 and 2011 were done. The following situations were found: (i) systematic underfunding of trauma patients in the G-DRG-Version 2008, especially trauma patients with acute paraplegia; (ii) participation in the official G-DRG development for 2011 with 13 proposals which were largely realised; (ii) the majority of cases with cost-covering in the G-DRG version 2011; (iv) significant improvements in the quality of statistical criteria; (v) overfunded trauma patients with high intensive care costs; (vi) underfunding for clinically relevant critically injured patients not identified in the G-DRG system. The quality of the G-DRG system is measured by the

    The reimbursement of intensive care and nursing services in the German health system is based on the diagnosis-related groups (G-DRG) system. Due to the lack of a central hospital planning, the G‑DRG system has become the most important influence on the development of the German health system. Compared to other countries, intensive care in Germany is characterized by a high number of intensive care beds, a low nurse-to-patient ratio, no official definition of the level of care, and a minimal available data set from intensive care units (ICUs). Under the given circumstances, a shortage of qualified intensive care nurses and physicians is currently the largest threat for intensive care in Germany. To address these deficiencies, we suggest the following measures: (1) Integration of ICUs into the levels of care which are currently developed for emergency centers at hospitals. (2) Mandatory collection of structured data sets from all ICUs including quality criteria. (3) A reform of intensive care and nursing reimbursement under consideration of adequate staffing in the individual ICU. (4) Actions to improve ICU staffing and qualification.

    For more than 30 years, there has been close cooperation between Japanese and German scientists with regard to information systems in health care. Collaboration has been formalized by an agreement between the respective scientific associations. Following this agreement, two joint workshops took place to explore the similarities and differences of electronic health record systems (EHRS) against the background of the two national healthcare systems that share many commonalities. To establish a framework and requirements for the quality of EHRS that may also serve as a basis for comparing different EHRS. Donabedian's three dimensions of quality of medical care were adapted to the outcome, process, and structural quality of EHRS and their management. These quality dimensions were proposed before the first workshop of EHRS experts and enriched during the discussions. The Quality Requirements Framework of EHRS (QRF-EHRS) was defined and complemented by requirements for high quality EHRS. The framework integrates three quality dimensions (outcome, process, and structural quality), three layers of information systems (processes and data, applications, and physical tools) and three dimensions of information management (strategic, tactical, and operational information management). Describing and comparing the quality of EHRS is in fact a multidimensional problem as given by the QRF-EHRS framework. This framework will be utilized to compare Japanese and German EHRS, notably those that were presented at the second workshop.

    The principal point of the author was to discuss energy systems (ES) in transition, transition addresses the next 10-25 years, and strategy of the transition. He considers different scenarios of future development of ES. Further he presents considerations elaborated during the last years on the concept of novel horizontally integrated ES which gives promise to be at least an approximation to the desired object of no emissions. The main ideas of the concept are: to decompose and thereby clean all the primary inputs before they are brought to combustion; to develop a network combining all the primary inputs to an integrated supply structure of high absorption, buffer, and storage capacity that resembles in some way the supply and utility functions of the well established electric grid but completes it at best on the basis of mass flows; to achieve a high flexibility in supplying the final energy. The author considers the long run perspective of hydrogen, solar, and nuclear energy with respect to alternative energy sources. 6 refs, 24 figs

    The 13th amendment to the German Atomic Energy Act, which was adopted by the German federal parliament on June 30 and entered into force on August 6, 2011, must be judged in the light of its genesis. Federal Chancellor Merkel, in her government declaration of June 9, 2011, had mentioned topics such as residual risk, safety standards, and risk assumptions, on which the federal government, in the week after the event of March 11, 2011, had commissioned the Advisory Committee on Reactor Safeguards (RSK) to conduct a comprehensive safety review of all German nuclear power plants, and appointed an Ethics Committee to write an opinion on safe energy supply. On the basis of quickly drafted reports, the federal cabinet, without any international harmonization (EU, IEA), adopted a draft opt out law on June 6, 2011. How should the declarations by the Federal Chancellor on June 9, 2011 be classified in terms of atomic energy law? In her words, it all revolved around the residual risk. The debate, which has been shifted to the realm of constitutional law, is open to considerations and steps to attack the new opt out law on grounds of material unconstitutionality (violation of the property guarantee under Sec. 14 or the principle of equality under Art.3 of the Basic Law). As far as final storage is concerned, the amendment to the German Atomic Energy Act announced still for this year, also for transposition of the EURATOM Directive of July 19, 2011 about nuclear waste management, the ''re-assessment of the residual risk'' is not likely to play a role. All these events are reminiscent of a sentence by former Federal Chancellor Schmidt: ''The history of the NATO dual-track decision remains a textbook case showing that even in a democracy emotions using ethical arguments, mixed with demagogy, can become strong enough to cast aside balanced reason.'' There is also a distinction by Max Weber between ''ethics of ideology

The implications are supposed to affect the generation mix of utilities, distribution grid utilization, and electricity price. Using a techno-economic optimization model of a household system, we endogenously dimension PV system and stationary battery storage (SBS). The results of the reference scenario show positive net present values (NPV) for PV systems of approx. 500–1,800 EUR/kW_p and NPV for SBS of approx. 150–500 EUR/kWh. Main influences are the demand of the households, self-consumption rates, investment costs, and electricity prices. We integrate electric vehicles (EV) with different charging strategies and find increasing NPV of the PV system and self-consumption of approx. 70%. With further declining system prices for solar energy storage and increasing electricity prices, PV systems and SBS can be profitable in Germany from 2018 on even without a guaranteed feed-in tariff or subsidies. Grid utilization substantially changes by households with EV and PV-SBS. We discuss effects of different incentives and electricity tariff options (e. g. load limits or additional demand charges). Concluding, solar energy storage systems will bring substantial changes to electricity sales. - Highlights: • Domestic photovoltaics (PV) and storage systems are techno-economically analyzed. • PV & storage are profitable in the medium term due to high self-consumption rates. • Controlled electric vehicle charging improves load flexibility and self-generation. • External procurement of electricity drastically changes and decreases to 48–58%. • Dynamic tariffs e. g. with load limits or demand charges incentivize load shifting.

  6. The 2002 amendment to the German atomic energy act concerning the phase-out of nuclear power

    International Nuclear Information System (INIS)

    Vorwerk, A.

    2002-01-01

    The phase-out of the use of nuclear power for electricity production has now been legally regulated by the 2002 Atomic Energy Act, based on the Agreement between the German Government and the energy utilities. The provisions of this Act comply with constitutional and European law, and take account of Germany's international commitments. The new 2002 Atomic Energy Act is supplemented by additional steps towards the phase-out, in particular in the area of nuclear disposal. These steps are being taken primarily within the framework of a planned national disposal plan and a procedure to be enveloped for the selection of a location for a final disposal site for radioactive wastes. The key task for the Laender authorities and the Federal Ministry for the Environment, Nature Conservation and Nuclear Safety continues to be to ensure that operators of nuclear power plants comply with a high standard of safety during the residual operating periods of their plants.

    As renewable energy use expands there will be a need to develop ways to balance its variability. Storage is one of the options. Presently the main emphasis is for systems storing electrical power in advanced batteries (many of them derivatives of parallel developments in the electric vehicle field), as well as via liquid air storage, compressed air storage, super-capacitors and flywheels, and, the leader so far, pumped hydro reservoirs. In addition, new systems are emerging for hydrogen generation and storage, feeding fuel cell power production. Heat (and cold) is also a storage medium and some systems exploit thermal effects as part of wider energy management activity. Some of the more exotic ones even try to use gravity on a large scale. This short book looks at all the options, their potentials and their limits. There are no clear winners, with some being suited to short-term balancing and others to longer-term storage. The eventual mix adopted will be shaped by the pattern of development of other balancing measures, including smart-grid demand management and super-grid imports and exports.

  8. THE RECONFIGURATION OF THE JUDGE`S ROLE IN THE ROMANO-GERMANIC LAW SYSTEM

    Directory of Open Access Journals (Sweden)

    ELENA ANGHEL

    2013-05-01

    Full Text Available The role assigned to the judge varies from one legal system to another. In the Anglo-Saxon legal systems, in the context of the absence of an independent legislative body, judge is the one who creates law; his mission consists in solving a specific case, given the existing judicial precedents; if he can not find an appropriate rule of law, the judge has to create one and to apply it. On the other hand, in the continental system, creation of law is the mission of the legislator. Evolving under the influence of Roman law, the continental law systems differ from the Anglo-Saxons by: the assuming of Corpus iuris civilis; the tendency to abstraction, leading to the creation of a rational law; the rule of law, with the consequence of blurring the role of jurisprudence. In spite of these essential differences, the last decades of the twentieth century have found out the convergence of the written coded system and the common law system. Thus, the increasing of the legislature`s role in common law system is accompanied by the reconsideration of the judge`s role in the Roman-Germanic legal system. While Anglo-Saxons accept the "compromise" of coding, Continentals shyly step towards rethinking the status of law source of the jurisprudence. History has shown that, one by one, law and jurisprudence have disputed the the role of prime creator of law. Emphasizing the creative force of jurisprudence, Vladimir Hanga wrote: "The law remains in its essence abstract, but the appreciation of the jurisprudence makes it alive, as the judge, understanding the law, examining the interests of parties and taking inspiration from equity, ensures the ultimate purpose of the law: suum cuique tribuere”1. However, as we shall see below, in the Roman-Germanic law system, the creative role of jurisprudence still raises controversy.

    Franz, D; Roeder, N; Hörmann, K; Alberty, J

    2007-07-01

    The German DRG system has been further developed into version 2007. For ENT and head and neck surgery, significant changes in the coding of diagnoses and medical operations as well as in the the DRG structure have been made. New ICD codes for sleep apnoea and acquired tracheal stenosis have been implemented. Surgery on the acoustic meatus, removal of auricle hyaline cartilage for transplantation (e. g. rhinosurgery) and tonsillotomy have been coded in the 2007 version. In addition, the DRG structure has been improved. Case allocation of more than one significant operation has been established. The G-DRG system has gained in complexity. High demands are made on the coding of complex cases, whereas standard cases require mostly only one specific diagnosis and one specific OPS code. The quality of case allocation for ENT patients within the G-DRG system has been improved. Nevertheless, further adjustments of the G-DRG system are necessary.

    The reliability analyses for Phase B of the German Risk Study taken into account an improved reliability data base, best-estimate minimal requirements for the relevant system functions and the design modifications, which have been carried out after completion of Phase A. These points and their influence on the frequency of core melt accidents are discussed, emphasizing the reliability data. Although the detailed evaluation of operating experience for the estimation of the reliability data does result in an increase of contributions, the best-estimate minimal requirements and the system modifications carried out for the reference plant reduce the core melt frequency due to those initiating events which were dominant in Phase A of the German Risk Study. The detailed investigation of additional initiating events which had already been recognized as important during Phase A leads to additional contributions to the frequency of core melt accidents. Such initiating events are the main steam line break and the steam generator tube rupture and altogether, the evaluated contributions to the frequency of core melt are lower than the values assessed in Phase A.

    Löhrer, M.; Ziesen, N.; Altepost, A.; Saggiomo, M.; Gloy, Y. S.

    2017-10-01

    The mid-sized embossed German textile industry must face social challenges e.g. demographic change or technical changing processes. Interaction with intelligent systems (on machines) and increasing automation changes processes, working structures and employees’ tasks on all levels. Work contents are getting more complex, resulting in the necessity for diversified and enhanced competencies. Mobile devices like tablets or smartphones are increasingly finding their way into the workplace. Employees who grew up with new forms of media have certain advantages regarding the usage of modern technologies compared to older employees. Therefore, it is necessary to design new systems which help to adapt the competencies of both younger and older employees to new automated production processes in the digital work environment. The key to successful integration of technical assistance systems is user-orientated design and development that includes concepts for competency development under consideration of, e.g., ethical and legal aspects.

    Vollerthun, A.; Wieser, M.

    2002-03-01

    Since Europe is considering to establish a "market-driven" European Global Navigation Satellite System, the German Center of Aerospace initiated a market research to justify a German investment in such a European project. The market research performed included the following market segments: aviation, railway, road traffic, shipping, surveying, farming, military, space applications, leisure, and sport. In these market segments, the forementioned inputs were determined for satellite navigation hardware (receivers) as well as satellite navigation services. The forecast period was from year 2007 to 2017. For the considered period, the market amounts to a total of DM 83.0 billion (approx. US $50 billion), whereas the satellite navigation equipment market makes up DM 39.8 billion, and charges for value-added-services amount to DM 43.2 billion. On closer examination road traffic can be identified as the dominant market share, both in the receiver-market and service-market. With a share of 96% for receivers and 73% for services the significance of the road traffic segment becomes obvious. The second part of this paper investigates the effects the market potential has on the Value-Adding-Chain. Therefore, all participants in the Value-Adding-Chain are identified, using industrial cost structure models the employment effect is analyzed, and possible tax revenues for the state are examined.

  1. Levelling vs competition – political trend reversal in the German healthcare system?

    Directory of Open Access Journals (Sweden)

    Sascha Wolf

    2014-12-01

    Full Text Available For almost 20 years, the German federal government has declared that competition is the key to ensuring the financial sustainability of the healthcare system. The aim of this paper is to investigate if German government indeed has followed a direct path to enhancing competition. For this purpose, a qualitative analysis of the most important healthcare reform acts has been conducted. In conclusion, especially since the introduction of the Health Fund in 2009, a clear trend towards more levelling and regulation can be observed. This trend is confirmed by the most recent healthcare reform act in June 2014. The abolishment of flat-rate premiums is the expression of the government’s fear that competitive pressure could endanger the solvency and viability of sickness funds (statutory health insurance funds. In contrast, on the market for selective contracts, an ambivalent picture emerges. On the one hand, several possibilities for establishing new forms of healthcare and strengthening competition have been introduced. On the other hand, sickness funds as well as service providers are often reluctant to enter into selective contracts.

    2018-02-15

    According to German law, liability for damage caused by radioactivity can arise from several regulations. In most cases, liability under the Paris Convention on Third Party Liability in the Field of Nuclear Energy, which applies in the field of nuclear power, is at the forefront of discussion. According to paragraph 26 of the German Atomic Energy Act, liability is somewhat in the shadow of the Paris Convention. It applies to the handling of radioactivity in medicine, research and industry (e.g. for test emitters) as well as activities involving natural and depleted uranium and nuclear fusion. The article outlines the basic elements of liability under Section 26 of the German Atomic Energy Act, which may become increasingly important in future due to recent developments such as the phasing out of nuclear power in Germany.

  6. Foreign competition and disintermediation: no threat to the German banking system?

    Directory of Open Access Journals (Sweden)

    Claudia M. Buch

    2000-06-01

    Full Text Available The German financial system is characterized by low degrees of penetration by foreign commercial banks and of (bank disintermediation compared to, for instance, the United States. This could be attributed to the fact that universal banking in Germany creates implicit barriers to entry. Yet, regulatory and informational differences which are unrelated to universal banking could be responsible for the observed difference. This paper provides a stylized theoretical model of the banking industry, which suggests that market segmentation and limited market entry can be due to a number of factors, including information costs. Preliminary empirical evidence does not provide clear evidence for the hypothesis that universal banking is the reason for the observed differences in financial systems.

  7. Farm management information systems: A case study on a German multifunctional farm

    2014-01-01

    Full Text Available Accurate and easy to use Farm Management Information Systems (FMIS are of fundamental importance for a successful operational farm management. However, still today many farmers do not use FMISs for various reasons, like lack of knowledge and the complexity of many available FMISs. In particular for small to medium-sized farms and for multifunctional farms appropriate FMISs hardly exist. This paper aims on the deduction of a concrete FMIS from a general FMIS. The concrete FMIS has to focus on the needs of medium-sized and multifunctional farms. This means that the farmer has to be empowered to allocate the scarce resources of the farm. Therefore, we picked a German farm from the state North Rhine Westphalia as a case-study to apply a system analysis. The case study farm helps to identify and to analyze relevant material and information flows, production processes, and their interconnections and synergies.

    As well for optimized emergency management in individual cases as for optimized mass medicine in disaster management, the principle of the medical doctors approaching the patient directly and timely, even close to the site of the incident, is a long-standing marker for quality of care and patient survival in Germany. Professional rescue and emergency forces, including medical services, are the "Golden Standard" of emergency management systems. Regulative laws, proper organization of resources, equipment, training and adequate delivery of medical measures are key factors in systematic approaches to manage emergencies and disasters alike and thus save lives. During disasters command, communication, coordination and cooperation are essential to cope with extreme situations, even more so in a globalized world. In this article, we describe the major historical milestones, the current state of the German system in emergency and disaster management and its integration into the broader European approach.

    Hvelplund, F.

    2001-01-01

    The 'political quota-/certificate price market' system introduces an inefficient competition between energy robots, and weakens the increasingly important competition between equipment producers. It hampers the competition between investors by making it difficult for neighbours and local investors to invest in wind turbines. Due to its mono price character, it gives too high profits to wind turbine owners at very good wind sites, and not high enough to wind turbine owners at poor wind sites. The 'political quota-/certificate price market' system is very far from being a market model, as the RE amount is politically decided and the certificate market price is also political influenced. The conclusion, therefore, is that it is time to find a RE governance model that considers the specific needs and characteristics of RE technologies. The present analysis strongly indicates that a 'political price-/amount market' model in this connection is far better than the 'political quota-/certificate price market' model. Furthermore, a common EU model, based on the principle of site efficiency, would be much more flexible, cheaper and easier to pursue than the 'political quota-/certificate price market', or mono price model, which is designed for uranium and fossil fuel technologies, and represents a governance model designed for the technologies of yesterday.

    The simultaneous implementation of the 'Transition energetique' process in France and of the 'Energiewende' process in Germany has resulted in the signature of a number of cooperation agreements between the two States. Since both these energy transition processes are largely based on decentralising energy supplies, close local authority cooperation looks promising. The TANDEM project is jointly led by two local authority networks, Energy Cities and Klima-Buendnis, with co-funding from ADEME (French Environment and Energy Management Agency) and UBA (German Federal Environment Agency). The TANDEM project provides French and German local authorities with a unique opportunity to share information and cooperate on climate protection issues in order to: provide improved mutual understanding of the situation, challenges and framework of climate and energy policies; encourage exchanges on the obstacles and leverages impeding or fostering the attainment of ambitious energy and climate objectives and encourage knowledge transfer; boost close cooperation between local authorities from both countries, involving local stakeholders and citizens; implement the first stages of cooperation projects during the lifetime of the TANDEM project and lay solid foundations for long-term cooperation; relay local authorities' claims and concerns at both national and European levels, aimed at providing them with greater latitude and freedom of action. Approaches specific to each country have been developed to promote energy transition at the local level. A comparative analysis of existing practices, tools and experiences involving research work and interviews will be conducted and made available to the participating authorities as well as to national organisations. This analysis will be used by national organisations to develop and enhance their action and by local authorities to improve mutual understanding during their discussions.

    Full Text Available Multi-Criteria Decision Analysis (MCDA can assist local decision processes towards selecting renewable energy systems as it is able to manage qualitative data and offers opportunities to integrate knowledge from local stakeholders. However, little experience is available regarding practical applications of MCDA in real decision processes in communities on their path towards a renewable energy supply. Within the “Bioenergy-Region Ludwigsfelde” project, an MCDA evaluation has been applied to a small village on its way to becoming a “bioenergy village”. Here, MCDA has been combined with already established tools accompanying the process to becoming a “bioenergy village”, such as planning workshops, citizens’ meetings and best-practice trips. A comprehensive set of sustainability criteria was applied aimed at addressing the questions of local actors. An emphasis was placed on social criteria that comprise the perceived values of local impacts. In general, it was observed that MCDA provides many benefits for this application context. In particular, the group weighting using the SIMOS method demonstrated good results in the process. However, for real-world applications of MCDA, the challenge of data compilation in particular must be addressed.

    Background  In the German hospital reimbursement system (G-DRG) endoscopic procedures are listed in cost center 8. For reimbursement between hospital departments and external providers outdated or incomplete catalogues (e. g. DKG-NT, GOÄ) have remained in use. We have assessed the cost for endoscopic procedures in the G-DRG-system. Methods  To assess the cost of endoscopic procedures 74 hospitals, annual providers of cost-data to the Institute for the Hospital Remuneration System (InEK) made their data (2011 - 2015; § 21 KHEntgG) available to the German-Society-of-Gastroenterology (DGVS) in anonymized form (4873 809 case-data-sets). Using cases with exactly one endoscopic procedure (n = 274 186) average costs over 5 years were calculated for 46 endoscopic procedure-tiers. Results  Robust mean endoscopy costs ranged from 230.56 € for gastroscopy (144 666 cases), 276.23 € (n = 32 294) for a simple colonoscopy, to 844.07 € (n = 10 150) for ERCP with papillotomy and plastic stent insertion and 1602.37 € (n = 967) for ERCP with a self-expanding metal stent. Higher costs, specifically for complex procedures, were identified for University Hospitals. Discussion  For the first time this catalogue for endoscopic procedure-tiers, based on § 21 KHEntgG data-sets from 74 InEK-calculating hospitals, permits a realistic assessment of endoscopy costs in German hospitals. The higher costs in university hospitals are likely due to referral bias for complex cases and emergency interventions. For 46 endoscopic procedure-tiers an objective cost-allocation within the G-DRG system is now possible. By international comparison the costs of endoscopic procedures in Germany are low, due to either greater efficiency, lower personnel allocation or incomplete documentation of the real expenses. © Georg Thieme Verlag KG Stuttgart · New York.

    Full Text Available At the European level the recognition of local self-government is a peaceful matter after being approved in the European Charter of Local Autonomy. However, the scope of this local financial autonomy varies according to the model of public finances that each country adopts. In this article we analyze the German and British models of local finance, two opposite examples in the way of organizing their treasure that directly affect the scope of the local autonomy of their municipalities. After a first part where the legal basis of the local autonomy is analyzed, the main sources of municipal financing are studied in each model, and it concludes with an assessment of the financial autonomy of the local entities within the Spanish system in comparison with the exposed models.

  3. Smart Energy Systems and Energy Transition

    2016-01-01

    Transition to decarbonized energy systems is becoming more attractive with fall of investment costs of renewables and volatile prices and political insecurity of fossil fuels. Improving energy efficiency, especially of buildings and transport, is important, but due to long life of buildings, it will be a slow way of decarbonization. The renewable energy resources are bountiful, especially wind and solar, while integrating them into current energy systems is proving to be a challenge. Solar has reached grid parity making it cheapest electricity source for retail customers in most of the World, creating new prosumer markets. It has started to reach cost parity in sunny countries, and soon solar energy will be cheapest everywhere. The limit of cheap and easy integration for wind is around 20% of yearly electricity generation, while a combined wind and solar may reach 30%. Going any further asks for implementation of completely free energy markets (involving day ahead, intraday and various reserve and ancillary services markets), demand response, coupling of wholesale and retail energy prices, and it involves integration between electricity, heat, water and transport systems. The cheapest and simplest way of increasing further the penetration of renewables is integrating power and heating/cooling systems through the use of district heating and cooling (which may be centrally controlled and may have significant heat storage capacity), since power to heat technologies are excellent for demand response. District cooling is of particular importance to historic cities that want to remove split systems from their facades. In countries with low heat demand water supply system may be used to increase the penetration of renewables, by using water at higher potential energy as storage media, or in dry climates desalination and stored water may be used for those purposes, and reversible hydro may be used as balancing technology. Electrification of personal car transport allows

    A review of the energy situation with regard to energy management and technological developments in Germany is presented. It is observed that the industrial consumption of energy is considerably lower than that of households and authorities of all kinds, leading to the conclusion that the greatest scope for saving on energy raw materials, particularly oil, lies in the area of households and small consumption areas. Some data and measures for conservation in the five most energy-intensive industries are briefly discussed. Examples of the national use of energy are given. (MCW)

    2006-03-01

    The German refined diagnosis-related-groups (G-DRG) system was introduced on 1st January 2003, initially on a voluntary basis and on 1st January 2004 the use of a G-DRG costing for stationary hospital treatment became obligatory. The possibility of a description of acute and chronic pain therapy in the G-DRG system was initially rudimentary and not logically planned and also a fair allotment of proceeds according to resources was not possible. By further development of the G-DRG system, pain therapeutic treatment could be improved in some areas, but in others it still remains unsatisfactory. This article offers a summary of the underlying systematics of the G-DRG system and consideration of chronic and current pain therapy in the G-DRG system 2006. In addition to information on currently available possibilities of a pain therapeutical coding in conformation with the G-DRG system, the tasks which are still outstanding will be outlined.

    2003-01-01

    The Polish energy-system needs intensive investments in new technologies, which are energy efficient, clean and cost effective. Since the early 1990s, the Polish economy has had practically full access to modern technological devices, equipment and technologies. Introducing new technologies is a difficult task for project teams, constructors and investors. The author presents a set of principles for project teams useful in planning and energy modernisation. Several essential features are discussed: Energy-efficient appliances and systems; Choice of energy carriers, media and fuels; Optimal tariffs, maximum power and installed power; Intelligent, integrated, steering systems; Waste-energy recovery; Renewable-energy recovery. In practice there are several difficulties connected with planning and realising good technological and economic solutions. The author presents his own experiences of energy-system modernisation of industrial processes and building new objects. (Author)

    For the simulation of severe accident propagation in containments of nuclear power plants it is necessary to assess the efficiency of a severe accident measures under conditions as realistic as possible. Therefore the German containment code system COCOSYS is under development and validation at GRS. The main objective is to provide a code system on the basis of mostly mechanistic models for the comprehensive simulation of all relevant processes and plant states during severe accidents in the containment of light water reactors covering the design basis accidents, too. COCOSYS is being used for the identification of possible deficits in plant safety, qualification of the safety reserves of the entire system, assessment of damage-limiting or mitigating accident management measures, support of integral codes in PSA level 2 studies and safety evaluation of new plants. COCOSYS is composed for three main modules, which are separate executable files. The communication is realized via PVM (parallel virtual machine). The thermal hydraulic main module (THY) contains several specific models relevant for the simulation of severe accidents. Beside the usual capabilities to calculate the gas distribution and thermal behavior inside the containment, there are special models for the simulation of Hydrogen deflagration, pressure suppression systems etc. Further detailed models exist for the simulation of safety systems, like catalytic recombiners (PAR's), safety relief valves (used in WWR-440/V-230 type plants), ice condenser model, pump and spray system models for the complete simulation of cooling systems. The aerosol and fission product part (AFP) describes the aerosol behavior of nonsoluble and as well as hygroscopic aerosols, iodine chemistry and fission transport. Further the decay process of nuclides is considered using ORIGIN like routines. The corium concrete interaction (CCI) main module is based on an improved version of WECHSL extended by the ChemApp module for the

    2015-04-01

    The option of adapting to climate change is becoming more and more important in climate change policy. Hence, responding to climate change now involves both mitigation to address the cause and adaptation as a response to already ongoing and expected changes. These changes also have relevance for the current and future energy sector in Germany. An energy sector that in the course of the German Energiewende also has to deal with a fundamental shift in energy supply from fossil fuel to renewable energies in the next decades. Thereby it needs to be considered that the energy sector is one critical infrastructure in the European Union that needs to be protected. Critical infrastructures can be defined as organisations or facilities of special importance for the country and its people where failure or functional impairment would lead to severe supply bottlenecks, significant disturbance of public order or other dramatic consequences. Regarding the adaptation to climate change, the main question is, whether adaptation options will be implemented voluntarily by companies or not. This will be the case, when the measure is considered a private good and is economically beneficial. If, on the contrary, the measure is considered a public good, additional incentives are needed. Based on a synthesis of the current knowledge regarding the possible impacts of climate change on the German energy sector along its value-added chain, the paper points out, that the power distribution and the grid infrastructure is consistently attributed the highest vulnerability. Direct physical impacts and damages to the transmission and distribution grids, utility poles, power transformers, and relay stations are expected due to more intense extreme weather events like storms, floods or thunderstorms. Furthermore fundaments of utility poles can be eroded and relay stations or power transformers can be flooded, which might cause short circuits etc. Besides these impacts causing damage to the physical

    Full Text Available A coastal observing system for Northern and Arctic Seas (COSYNA aims at construction of a long-term observatory for the German part of the North Sea, elements of which will be deployed as prototype modules in Arctic coastal waters. At present a coastal prediction system deployed in the area of the German Bight integrates near real-time measurements with numerical models in a pre-operational way and provides continuously state estimates and forecasts of coastal ocean state. The measurement suite contributing to the pre-operational set up includes in situ time series from stationary stations, a High-Frequency (HF radar system measuring surface currents, a FerryBox system and remote sensing data from satellites. The forecasting suite includes nested 3-D hydrodynamic models running in a data-assimilation mode, which are forced with up-to-date meteorological forecast data. This paper reviews the present status of the system and its recent upgrades focusing on developments in the field of coastal data assimilation. Model supported data analysis and state estimates are illustrated using HF radar and FerryBox observations as examples. A new method combining radial surface current measurements from a single HF radar with a priori information from a hydrodynamic model is presented, which optimally relates tidal ellipses parameters of the 2-D current field and the M2 phase and magnitude of the radials. The method presents a robust and helpful first step towards the implementation of a more sophisticated assimilation system and demonstrates that even using only radials from one station can substantially benefit state estimates for surface currents. Assimilation of FerryBox data based on an optimal interpolation approach using a Kalman filter with a stationary background covariance matrix derived from a preliminary model run which was validated against remote sensing and in situ data demonstrated the capabilities of the pre-operational system.

  12. Interdependencies between fossil fuel and renewable energy markets. The German biodiesel market

    2010-12-15

    With this paper, we provide the first quantitative investigation of vertical price transmission in the biodiesel supply chain in Germany with the focus on the developments during the food crisis and the impact of subsidized US biodiesel exports. With the strong promotion of the production and use of biodiesel during the first half of the past decade, the German biodiesel market became the largest national biodiesel market worldwide. This analysis utilizes prices of rapeseed oil, soya oil, biodiesel and crude oil over a sample period covering the rapid growth of the German demand in 2002 until its decline in 2009. The effects of both the market development and different policies on price transmission are analyzed in detail. Due to the numerous changes in the market, a regime-dependent Markov-switching vector error correction model is applied. The results indicate that regimes with differing error-correction behavior govern the transmission process among the various prices. Evidence was found for a strong impact of crude oil price on biodiesel prices, and of biodiesel prices on rapeseed oil prices. However, in both cases, the price adjustment behavior is found to be regime dependent, and the regime occurrence in both market segments shows similar patterns. In relation to crude oil a weak adjustment of biodiesel prices is found to be dominating in the phase of market expansion. This changed from 2007 on when stronger error-correction is found, reflected by a stronger role of the crude oil price developments. In the relationship of biodiesel to the vegetable oils, most of the growth period was dominated by a regime characterized by weak price adjustments. From 2007 on, past own price changes and past changes in soya oil prices had a strong impact particularly on rapeseed oil prices. The biodiesel price development was less important. Reasons for this are substantial changes in the market structure. The biodiesel market developed as an insulated market; biodiesel was

  14. Life extension of German nuclear power plants only with the consent of the Federal Council? The importance and extent of the need for consent to an amendment to the German Atomic Energy Act

    International Nuclear Information System (INIS)

    Schneider, Horst

    2010-01-01

    In its coalition agreement of October 26, 2009, the new German federal government plans ''to extend the service life of German nuclear power plants while, at the same time, complying with the strict German and international safety standards.'' This has triggered a debate not only about (nuclear) energy, as in the past election campaign in the summer of 2009, but also about the constitutional law issue whether an amendment to the Atomic Energy Act resulting in longer operating life of nuclear power plants required the consent of the Federal Council (the ''Bundesrat,'' the second chamber of parliament). After the election to the state parliament in North Rhine-Westphalia on May 9, 2010, majority in the Federal Council changed. As a consequence, no consent to an amendment to the Atomic Energy Act must be expected. In view of the large number of recent statements about constitutional law in opinions for various federal and ministerial accounts as well as firms and associations, the outline by R. Scholz in the May issue of atw 2010 will be followed in this issue by the key points of examination of the need for consent, under aspects of constitutional law, and an attempt will be made to explain the evaluations underlying the generation of a legal concept about these items. The decision by the German Federal Constitutional Court of May 4, 2010, published on June 11, 2010, plays a major role in this respect because it established clarity in some important aspects of a legal subject matter in the field of state admini-stration on behalf of the federation, albeit in the field of air traffic law, not nuclear law. However, the structures of the norms in the German Basic Law (Art. 87c and Art. 87d, para.2) to be applied are almost identical. The energy policy and energy economy aspects of a plant life extension are considered along with the option of an appeal to the Federal Constitutional Court against any plant life extension. Finally, the key findings are summarized briefly

    2017-06-01

    This study aimed to empirically compare incident reporting systems (IRS) in two European countries and to explore the relationship of IRS characteristics with context factors such as hospital characteristics and characteristics of clinical risk management (CRM). We performed exploratory, secondary analyses of data on characteristics of IRS from nationwide surveys of CRM practices. The survey was originally sent to 2136 hospitals in Germany and Switzerland. Persons responsible for CRM in 622 hospitals completed the survey (response rate 29%). None. Differences between IRS in German and Swiss hospitals were assessed using Chi2, Fisher's Exact and Freeman-Halton-Tests, as appropriate. To explore interrelations between IRS characteristics and context factors (i.e. hospital and CRM characteristics) we computed Cramer's V. Comparing participating hospitals across countries, Swiss hospitals had implemented IRS earlier, more frequently and more often provided introductory IRS training systematically. German hospitals had more frequently systematically implemented standardized procedures for event analyses. IRS characteristics were significantly associated with hospital characteristics such as hospital type as well as with CRM characteristics such as existence of strategic CRM objectives and of a dedicated position for central CRM coordination. This study contributes to an improved understanding of differences in the way IRS are set up in two European countries and explores related context factors. This opens up new possibilities for empirically informed, strategic interventions to further improve dissemination of IRS and thus support hospitals in their efforts to move patient safety forward. © The Author 2017.

    2015-09-01

    Hospital inpatient stays are reimbursed on the basis of German diagnosis-related groups (G-DRG). The G-DRG classification system is based on complex coding guidelines. The Medical Review Board of the Statutory Health Insurance Funds (MDK) examines the encoding by hospitals and delivers individual expertises on behalf of the German statutory health insurance companies in cases in which irregularities are suspected. A study was conducted on the inter-rater reliability of the MDK expertises regarding the scope of the assessment. A representative sample of 212 MDK expertises was taken from a selected pool of 1 392 MDK expertises in May 2013. This representative sample underwent a double-examination by 2 independent MDK experts using a special software based on the 3MTM G-DRG Grouper 2013 of 3M Medica, Germany. The following items encoded by the hospitals were examined: DRG, principal diagnosis, secondary diagnoses, procedures and additional payments. It was analysed whether the results of MDK expertises were consistent, reliable and correct. 202 expertises were eligible for evaluation, containing a total of 254 questions regarding one or more of the 5 items encoded by hospitals. The double-examination by 2 independent MDK experts showed matching results in 187 questions (73.6%) meaning they had been examined consistently and correctly. 59 questions (23.2%) did not show matching results, nevertheless they had been examined correctly regarding the scope of the assessment. None of the principal diagnoses was significantly affected by inconsistent or wrong judgment. A representative sample of MDK expertises examining the DRG encoding by hospitals showed a very high percentage of correct examination by the MDK experts. Identical MDK expertises cannot be achieved in all cases due to the scope of the assessment. Further improvement and simplification of codes and coding guidelines are required to reduce the scope of assessment with regard to correct DRG encoding and its

    The study ascertains the equipment and material resources of German data centres for the reference year 2008 and predicts its development until the year 2015 in two scenarios (''business as usual'' and ''Green IT''). Similar studies for other countries or regions are not known so far. In the study a methodology is developed, which allows to calculate the number of data centres in different size classes and their average equipment with IT components and infrastructure elements such as air conditioning systems and power supplies. Reference products are defined and on this basis a detailed determination of the material composition of data centre components is made. This allows to make detailed statements on the material equipment of approximately 53,000 data centres in Germany. In the year 2008 in German Data centres approx.12.000 tonnes of electronics, 17,000 tonnes of copper, 7,000 tonnes of aluminium, 11,000 tonnes of plastics and 58 000 tonnes of iron were used. The electronic material contains 1.8 tonnes of gold, 7.5 tonnes of silver and 0.8 tonnes of palladium. Nearly 30% of the materials are bound in almost 50 major data centres. In the scenario ''business as usual'' the amount of electronics in the German data centres increases from 2008 to 2015 by about 60% up to 20,000 tonnes. This includes almost 3 tonnes of gold, 21 tonnes of silver and 1.8 tonnes of palladium. The amounts of copper, aluminium and iron will increase by over 50%. Even in the scenario ''Green IT'' when the energy needs of data centres in Germany decreases by 40%, the material stock in the data centres would not reduce, especially the electronic material will increase significantly by more than 20%. The study points to significant further research. In particular there is a need to ascertain detailed data on the material composition of IT products (servers, etc.).

    In this paper, we identify key drivers and barriers for the adoption of building energy retrofits in Germany, which is promoted by public policy as an important measure to address the future challenges of climate change and energy security. We analyze data from a 2009 survey of more than 400 owner-occupiers of single-family detached, semidetached, and row houses in Germany, that was conducted as a computer-assisted personal interview (CAPI). In the survey, respondents were asked directly for reasons for and against retrofitting their homes, but also faced a choice experiment involving different energy retrofit measures. Overall, we find that house owners who are able to afford it financially, for whom it is profitable, and for whom there is a favorable opportunity are more likely to undertake energy retrofit activities. The latter point seems to be of particular importance in explaining the persistent low retrofit rate in Germany. Our results suggest that professional energy advice could stimulate the demand for building energy retrofits. - Highlights: • Survey data of 400 owner-occupiers from Germany is analyzed. • Drivers and barriers for the adoption of building energy retrofits are identified. • Descriptive and econometric results underline the importance of economic factors. • The simulated incentive effect of expert recommendations is notable in magnitude. • Professional energy advice thus may help to stimulate energy retrofit activities

    Energy Technology Data Exchange (ETDEWEB)

    2011-11-30

    SEDS is an economy-wide energy model of the U.S. The model captures dynamics between supply, demand, and pricing of the major energy types consumed and produced within the U.S. These dynamics are captured by including: the effects of macroeconomics; the resources and costs of primary energy types such as oil, natural gas, coal, and biomass; the conversion of primary fuels into energy products like petroleum products, electricity, biofuels, and hydrogen; and lastly the end- use consumption attributable to residential and commercial buildings, light and heavy transportation, and industry. Projections from SEDS extend to the year 2050 by one-year time steps and are generally projected at the national level. SEDS differs from other economy-wide energy models in that it explicitly accounts for uncertainty in technology, markets, and policy. SEDS has been specifically developed to avoid the computational burden, and sometimes fruitless labor, that comes from modeling significantly low-level details. Instead, SEDS focuses on the major drivers within the energy economy and evaluates the impact of uncertainty around those drivers.

    2012-11-01

    This study examines the lobbying strategies employed by the interest organizations of Germany's energy industries in the process leading up to the EU's Renewable Energy Directive. How did they lobby, and what does this reveal about their perceptions of power relations in the EU? This report focuses on the most controversial part of the Directive: legal prescriptions for support mechanisms to increase the production of renewable energy in Europe. The utilities and the renewables industries disagreed deeply, with the utilities industry favouring an EU-wide green certificate scheme, while the renewables industry pressed for national feed-in tariffs. Nine interest organizations representing these sectors, five German and four at the EU level, serve as cases in this study. Expectations as to lobbying behaviour based on the two theories/theory perspectives of liberal intergovernmentalism (LI) and multi-level governance (MLG) are formulated and tested in a most-likely case design. Result: observations are better described by the MLG perspective than by LI.(auth)

    State-certified occupational physicians who work as civil servants in the Federal Republic of Germany are key players in the German Public Health system. They control i.e. the legal compliance in occupational health and participate in the occupational disease procedures. Despite the role model function of the German Public health system for many developing countries, this area of Public health is debated to have been hampered in the past years by a disregard concerning structural developments. Different databases were screened for occupational health benchmarks. Obtained data were compared to socioeconomic data and indices were calculated. The overall numbers of State-certified occupational physicians decreased in Germany between 1992 and 2012 from 136 to 86 (63 %). On the single state level, the ratios of State-certified occupational physicians per 1 Mio. working population ranged from 8 for the state of Saarland to 0.8 for the state of North Rhine Westphalia. A general difference was found for old versus new German states. Also, large differences were present for the ratios of State-certified occupational physicians per 10 6 employees towards public debt per capita (€) and the ratios of State-certified occupational physicians per Gross Domestic Product (GDP) in the 16 German states in 2012. In striking contrast to the WHO document on the Occupational safety and health (OSH) system that states in its executive summary that the human and institutional capacities of the German occupational health system are very strong in both quantity and quality, we here show extreme imbalances present at the single state levels that developed over the past 20 years. With a regard to the increasing complexity of the economic system a reversal of this trend should be demanded.

  12. What encourages local authorities to engage with energy performance contracting for retrofitting? Evidence from German municipalities

    Municipalities aiming at mitigating climate change by implementing new energy efficiency technologies face budgetary and capacity constraints. Outsourcing through energy service contracting could provide a solution. This paper reports results from a survey of 1298 municipalities concerning barriers to retrofitting public street lighting and the possible role of energy service contracting to overcome these barriers. Using a logistic regression analysis, the authors investigate determinants of opting for energy service contracts in the specific context of LED retrofits. Results point to an advantage of outsourcing in a financially and capacity-constrained environment, which corresponds with the main reasons for engaging in contracting: minimising investments and financial risks. However, municipalities often do not fully grasp the risks associated with retrofitting especially using a novel technology such as LED. In relation to that they underestimate the risk reduction potential of energy performance contracts (EPC). Previous experience with outsourcing increases the probability to engage in servitization although certain existing partnerships, particularly with utilities, prevent municipalities from considering energy performance contracts. Interestingly, engaging an energy consultant has a negative propensity to use energy service contracts, while pre-negotiated standardised contracts for energy performance contracts have a positive influence. - Highlights: •Barriers to retrofitting can be addressed through energy performance contracts (EPC). •Outsourcing has the potential to alleviate personnel and financial constraints. •Standardised contracts and previous experience with outsourcing facilitate use of EPC. •Engaging energy consultants has a negative influence on the willingness to adopt EPC. •Policy makers could support facilitators and standard contracts to boost EPC market.

    The aim of the paper is to show how Germany tries to improve the energy efficiency of the economy and reduce carbon dioxide emissions without affecting the competitiveness of the industry. Between 1990 to 1995 Germany has reduced its CO{sub 2} emission from 1029 to 933 million tonnes, which is equivalent to an emission reduction of 9%. To analyse and compare different options to reach the emission reduction target, multiple tools have been developed and can be used to help in setting policy priorities. The IKARUS model and database together with the use of energy efficiency indicators helps to keep the development of energy consumption and emission reduction on track to the reduction target. Voluntary agreements between industry and government had been worked out, to limit the emissions in the energy intensive sectors of the German industry. Results from the monitoring of this efforts will be presented together with a short evaluation of the factors influencing the improvements in energy efficiency. As energy related emissions can be reduced significantly by closing energy and material flows, the effect of recycling of energy intensive materials such as steel, glass, plastics, and paper is discussed. The possible role of renewables as energy carrier and feedstock is evaluated for the production of surfactants. If more oleochemical surfactants could be applied, this will help to reduce the CO{sub 2} emissions from the use of fossil fuels as feedstock. The efficiency improvement by cross cutting technologies will be discussed for furnaces, compressed air systems and electric motors. Most of these improvement potentials are economic at present energy prices, but some barriers for their application has to be overcome. One way to help decision makers in industry is the use of energy benchmarking. Benchmarking helps to analyse the energy efficiency of the own company in comparison to the competitors and to set appropriate targets and to prepare a road map of measures to

    2014-05-01

    In order to mitigate climate change, extraordinary measures are necessary in the future. The building sector, in particular, offers considerable potential for transformation to lower energy demand. On a national level, however, successful and far-reaching measures will likely be taken only if reliable estimates regarding future energy demand from different scenarios are available. The energy demand for space heating and cooling is determined by a combination of behavioral, climatic, constructional, and demographic factors. For two countries, namely Germany and the Netherlands, we analyze the combined effect of future climate and building stock changes as well as renovation measures on the future energy demand for room conditioning of residential buildings until 2060. We show how much the heating energy demand will decrease in the future and answer the question of whether the energy decrease will be exceeded by an increase in cooling energy demand. Based on a sensitivity analysis, we determine those influencing factors with the largest impact on the future energy demand from the building stock. Both countries have national targets regarding the reduction of the energy demand for the future. We provide relevant information concerning the annual renovation rates that are necessary to reach these targets. Retrofitting buildings is a win-win option as it not only helps to mitigate climate change and to lower the dependency on fossil fuels but also transforms the buildings stock into one that is better equipped for extreme temperatures that may occur more frequently with climate change. For the Netherlands, the study concentrates not only on the national, but also the provincial level, which should facilitate directed policy measures. Moreover, the analysis is done on a monthly basis in order to ascertain a deeper understanding of the future seasonal energy demand changes. Our approach constitutes an important first step towards deeper insights into the internal dynamics

    Full text: The global energy crisis is forcing every country worldwide to review its policies on energy. The environmental disaster at Japan's Fukushima Daiichi nuclear power plant has accelerated this process. Many people around the world are citing the disaster as evidence that nuclear power would endanger the survival of mankind on earth and should be banned. Today we need to focus more substantially on energy saving, especially using smart devices with low power consumption. We have also to review the approach to the exploitation of energy and move from a philosophy 'from the ground to the subsurface' to another 'from the earth to the sun'. This paper highlights the increasing importance of solar power in meeting energy needs while achieving security of supply and minimising carbon dioxide (CO{sub 2}) emissions. It deals also with the development of solar power plants, which require a supervisory control system that improves their efficiency and reliability. (author)

    The Energy Transition (''Energiewende'') is one of the hot topics of the political debate in Germany for some years. As a consequence of ongoing European integration, EU level politics have gained growing importance. The focus of this study is on the interaction of German and EU energy and climate policies. How have German actors influenced EU policy-making processes and in how far are EU policies relevant for national policy-making in Germany? Three case studies look at processes in the fields of electricity market regulation, renewable energy policy and climate protection between 2007 and 2013.

    Diagnosis-Related Groups (DRGs) are a patient classification system grouping related types of patients to the resources they have consumed. In this analysis, we compared pedicle and free flaps in plastic and reconstructive surgery in the actual German DRG system. After grouping common flaps while systematically modifying the diagnosis, the operative procedure(s), and the receptor site, reimbursement and thresholds of length of stay were identified. The mean value of the average length of stay was higher in free flaps as compared to pedicle flaps (15 vs. 9 days) and the mean reimbursement in free flaps was almost twice as high as in pedicle flaps (8 936 € vs. 4 582 €). Regarding the diagnosis, third-grade open fractures in pedicle flaps and full-thickness burns in free flaps are in the vanguard of reimbursement. Higher DRG conformity is generally found with free flaps. Different possibilities in coding the procedures and the strong dependence on the underlying diagnosis lead to variations of remuneration and length of stay, which are not explainable and sometimes even seem paradoxical. Furthermore, mixed calculation creates DRGs that lose the ability to describe the real effort. © Georg Thieme Verlag KG Stuttgart · New York.

  4. Decarbonization of Croatian Energy System

    2012-01-01

    Energy system decarbonization is reduction of greenhouse gases (CO 2 ) emission, chiefly from the fossil fuels (coal, oil, natural gas) combustion. The main objective of an energy system decarbonization is the climate change mitigation, and at the same time development of local industry and employment, better environment and health protection, as well as reduction of the fossil fuels import and foreign debt. Croatia has small fossil fuels reserves and large renewable energy sources (RES) reserves, energy efficiency (ENEF) is relatively low, and energy import, according to the actual Energy strategy 2009, should increase from 50% to 70% until 2020. Croatian energy system participates with about one third in the Croatian foreign trade deficit. The main measures of the Croatian energy system decarbonization should be: increasing ENEF (energy savings), switch from fossil fuels to RES, administrative measures (low carbon development strategy, environmental tax reform, and decoupling income from energy sales). By urgent application of these measures, Croatia could become fossil fuels free until the year 2050.(author)

    The objective of this paper is to identify and analyse factors that are important for winning acceptance of wind-energy parks on the local level. The developers of wind-energy parks need to know how to manage 'social acceptance' at the different stages of planning, realisation and operation. Five case studies in France and Germany focused on factors of success in developing a wind-energy project on a given site and illuminated how policy frameworks influence local acceptance. Our hypothesis is that these factors fall into two categories: institutional conditions, such as economic incentives and regulations; and site-specific conditions (territorial factors), such as the local economy, the local geography, local actors, and the actual on-site planning process (project management)

    Significant benefits are connected with an increase in the flexibility of the Danish energy system. On the one hand, it is possible to benefit from trading electricity with neighbouring countries, and on the other, Denmark will be able to make better use of wind power and other types of renewable energy in the future. This paper presents the analysis of different ways of increasing flexibility in the Danish energy system by the use of local regulation mechanisms. This strategy is compared with the opposite extreme, i.e. trying to solve all balancing problems via electricity trade on the international market. The conclusion is that it is feasible for the Danish society to include the CHP plants in the balancing of fluctuating wind power. There are major advantages in equipping small CHP plants as well as the large CHP plants with heat pumps. By doing so, it will be possible to increase the share of wind power from the present 20 to 40% without causing significant problems of imbalance between electricity consumption and production. Investment in increased flexibility is in itself profitable. Furthermore, the feasibility of wind power is improved

    An attempt is made to compare and judge the 'soft' and 'hard' technologies that have become standard terms in the discussion on future energy supply. This comparison is made difficult by the fact that the emphasis on 'soft' technology is not on economic but on sociopolitical factors. Present figures show that 'soft' technologies are the most capital-intensive of the alternative energy sources for the substitution of oil and gas. Also, one of their preconditions is a social change that is hard to imagine. At least from an economic point of view, further growth can only be realized the 'hard' way.

    Photovoltaics are one of the fastest growing energy sources in the world. Despite high costs and a limited energy yield, attractive support schemes particularly the German renewable energy law have paved the way for the strong market growth of this technology within the last decade. Here the question arises as to when photovoltaics will reach a competitive level in Germany without the support of subsidies. The prominent grid parity approach is simple and considered critical in this discussion. It is critical because of the different references regarding the costs of electricity generated by a newly installed PV system and the electricity price of private households, which consists of electricity generation, distribution, sales as well as taxes and duties on the one hand. On the other hand, there are different time references in the calculation of electricity generation costs and electricity prices of private households. Transferring the approach of Levelized Costs of Electricity (LCOE) to all power generation plants within the energy mix means a redefinition of the grid parity of photovoltaics will be carried out. Here the electricity generation costs of photovoltaics as well as the energy mix will be calculated in the same way. The LCOE calculation refers to the whole life cycle of every power generation plant. That is why a balance between the high investment costs of photovoltaics and the increasing operation costs of fossil fuelled power plants is made. It can be shown that the reaching of competitiveness of photovoltaics in Germany depends on structural changes in electricity generation and it is to be realized within the anticipated time frame until the year 2020.

    The German government has committed itself to a 40 percent reduction of climate-relevant gases by 2020, as compared to 1990. In 2007, the government presented an integrated energy and climate protection programme (IEKP) with a catalogue of measures to achieve this goal. The IEKP was to be revised from 2010 by monitoring every two years. If the monitoring were to show that the CO2 reduction goal could not be achieved by the measures taken, suggestions will be made on how to improve CO2 reduction technologies. This study, carried out on behalf of the Federal Minister of Environment, Conservation and Reactor Safety, presents a data base for this monitoring. It is based on work carried out by the Federal Environmental Office, the BMU, and other institutions. (orig.)

    Full Text Available This article is devoted to the description of the phraseological syntax of the modern German language «Was für + Sub1-4!». The relevance of the study is due to the insufficient study of this subject, but also to its high relevance for the practice of communication. The following methods were used in the research: descriptive, method of component analysis of the semantic structure of the sentence, syntactic modeling, phraseological analysis, transformation method, and also the method of etymological, contextual and discursive analysis. The phrase «Was für + Sub1-4!» is described in the structural, semantic, etymological, paradigmatic, syntagmatic, stylistic, phraseological and functional aspects. The article substantiates the phraseological status of the given phrase-scheme and its belonging to the phraseological subsystem of the language. It is established that the phraseological scheme has two obligatory components (unchangeable and variable, characterized by signs of reproducibility, structural and semantic stability and integrity, idiomatic and expressive, possesses an unchangeable structure serving as a model for constructing similar propositions. In general, the phraseology «Was für + Sub1-4!» is quite frequent in the practice of communication, which is due to its systemic and functional characteristics. Its use in colloquial speech increases the effectiveness of the communication process, gives it a relaxed character.

    We present our results on energy transfer between donor and acceptor molecules or quantum dots near a plasmonic nanoparticle. In such systems, the Förster resonance energy transfer is strongly modified due to plasmon-mediated coupling between donors and acceptors. The transfer efficiency is determined by a competition between transfer, radiation and dissipation that depends sensitively on system parameters. When donor and accepror spectral bands overlap with dipole surface plasmon resonance, the dominant transfer mechanism is through plasmon-enhanced radiative coupling. When transfer takes place from an ensemble of donors to an acceptor, a cooperative amplification of energy transfer takes place in a wide range of system parameters. (paper)

    In this report the authors describe results from technical and economic assessments carried out during the past year with support from the USDOE Hydrogen R&D Program. (1) Assessment of technologies for small scale production of hydrogen from natural gas. Because of the cost and logistics of transporting and storing hydrogen, it may be preferable to produce hydrogen at the point of use from more readily available energy carriers such as natural gas or electricity. In this task the authors assess near term technologies for producing hydrogen from natural gas at small scale including steam reforming, partial oxidation and autothermal reforming. (2) Case study of developing a hydrogen vehicle refueling infrastructure in Southern California. Many analysts suggest that the first widespread use of hydrogen energy is likely to be in zero emission vehicles in Southern California. Several hundred thousand zero emission automobiles are projected for the Los Angeles Basin alone by 2010, if mandated levels are implemented. Assuming that hydrogen vehicles capture a significant fraction of this market, a large demand for hydrogen fuel could evolve over the next few decades. Refueling a large number of hydrogen vehicles poses significant challenges. In this task the authors assess near term options for producing and delivering gaseous hydrogen transportation fuel to users in Southern California including: (1) hydrogen produced from natural gas in a large, centralized steam reforming plant, and delivered to refueling stations via liquid hydrogen truck or small scale hydrogen gas pipeline, (2) hydrogen produced at the refueling station via small scale steam reforming of natural gas, (3) hydrogen produced via small scale electrolysis at the refueling station, and (4) hydrogen from low cost chemical industry sources (e.g. excess capacity in refineries which have recently upgraded their hydrogen production capacity, etc.).

    Understanding what drives the regional implementation of renewable energy is a prerequisite for energy transitions toward a post-fossil-based energy economy. This paper presents an empirical analysis of driving factors for the regional implementation and use of renewable energy. We tested literature-derived driving factors in a comparative analysis of 18 selected study regions using Rough Set Analysis and performance analysis. We paid special attention to common combinations of driving factors, which we understand as established practices concerning the use and implementation of renewable energy. Our findings confirm most of the driving factors identified in the literature, for example the existence of key actors, knowledge exchange, or the use of goals and milestones. We also observe differences in key driving factors between highly successful and less successful regions, especially regarding funding opportunities. The results may support policy makers who aim to successfully implement renewable energy at a regional level. - Highlights: • We analyzed driving factors for RE implementation in 18 best-practice regions. • Most driving factors from transition and governance literature were confirmed. • We identified common successful practices concerning RE implementation.

    After the nuclear catastrophe in Fukushima Finland and Sweden have chosen completely different paths compared to Germany: both countries plan to build new nuclear power plants. The contribution discusses the historical development of nuclear power in these countries. In Sweden a political polarization exists between those who want to use renewable energies and those who expect increasing greenhouse gas emissions in case of nuclear power phaseout. In Finland no important anti-nuclear movement has been formed. The authors do not expect a change of policy in Sweden and Finland.

    International Nuclear Information System (INIS)

    2007-12-01

    Developing nuclear energy that is sustainable, safe, has little waste by-product, and cannot be proliferated is an extremely vital and pressing issue. To resolve the four issues through free thinking and overall vision, research activities of 'innovative nuclear energy systems' and 'innovative separation and transmutation' started as a unique 21st Century COE Program for nuclear energy called the Innovative Nuclear Energy Systems for Sustainable Development of the World, COE-INES. 'Innovative nuclear energy systems' include research on CANDLE burn-up reactors, lead-cooled fast reactors and using nuclear energy in heat energy. 'Innovative separation and transmutation' include research on using chemical microchips to efficiently separate TRU waste to MA, burning or destroying waste products, or transmuting plutonium and other nuclear materials. Research on 'nuclear technology and society' and 'education' was also added in order for nuclear energy to be accepted into society. COE-INES was a five-year program ending in 2007. But some activities should be continued and this roadmap detailed them as a rough guide focusing inventions and discoveries. This technology roadmap was created for social acceptance and should be flexible to respond to changing times and conditions. (T. Tanaka)

  7. Comparative Analysis of the Numeral Systems of Ígálà, Yoruba, German and English

    2012-01-01

    Full Text Available This study undertakes a comparative analysis of the numeral systems of Igala, Yoruba, English and German. An essential part of data collation for the study comprises compilation of comparative wordlists of Ígálà, Yoruba, German and English numeral systems in addition to the writer's personal observation and knowledge of the systems. The investigation reveals that the complexity of deriving especially non-basic numerals in the languages involves three predominant arithmetic processes of addition, subtraction (Yoruba in particular and multiplication in addition to certain grammatical processes, especially vowel elision, clipping, compounding and so on. In addition, the summary of the quasi constraints or derivational patterns for the languages reveals that whereas German and English maintain very similar patterns because of their very close affinity as sisters from the same parent, it is not so with Ígálà and Yoruba even though both belong to the same language family. Incorporating insights from optimality theory, the paper argues that even though numeracy and the constraints that ensure well-formedness of numerals are somewhat universal, parametric variations abound. The actual patterning of the sequences of the derivational processes in individual languages may be very similar but definitely not the same, no matter how closely related the languages concerned may be. If not, they would cease to represent core grammars of different languages.

    2017-09-01

    Full Text Available Since the majority of network concession contracts in Germany were set to expire some time between 2005 and 2016, a window of opportunity arose in which to rebuild and remunicipalise the local energy supply. As a result, 72 new local power companies were established in Germany within the space of just seven years (between early 2005 and late 2012. This paper provides an introduction to the topic of establishing municipal utilities in Germany. The findings were identified on the basis of the comprehensive screening of all newly established municipal utilities in Germany. Our analysis provides information about regional concentration, the size of municipalities, the legal forms of the newly founded municipal public utilities and the role of strategic partnerships. The key findings are that remunicipalisation is not a question of size and that knowledge gaps may be closed by entering into close strategic partnerships.

    2012-01-01

    Efficiency is one of the most frequently used terms in thermodynamics, and it indicates how well an energy conversion or process is accomplished. Efficiency is also one of the most frequently misused terms in thermodynamics and is often a source of misunderstanding. This is because efficiency is often used without being properly defined first. This book intends to provide a comprehensive evaluation of various efficiencies used for energy transfer and conversion systems including steady-flow energy devices (turbines, compressors, pumps, nozzles, heat exchangers, etc.), various power plants, cogeneration plants, and refrigeration systems. The book will cover first-law (energy based) and second-law (exergy based) efficiencies and provide a comprehensive understanding of their implications. It will help minimize the widespread misuse of efficiencies among students and researchers in energy field by using an intuitive and unified approach for defining efficiencies. The book will be particularly useful for a clear ...

    Full Text Available Wind is an attractive renewable source of energy. Recent innovations in research and design have reduced to a few alternatives with limited impact on residential construction. Cost effective solutions have been found at larger scale, but storage and delivery of energy to the actual location it is used, remain a critical issue. The Integrated Roof Wind Energy System is designed to overcome the current issues of urban and larger scale renewable energy system. The system is built up by an axial array of skewed shaped funnels that make use of the Venturi Effect to accelerate the wind flow. This inventive use of shape and geometry leads to a converging air capturing inlet to create high wind mass flow and velocity toward a vertical-axis wind turbine in the top of the roof for generation of a relatively high amount of energy. The methods used in this overview of studies include an array of tools from analytical modelling, PIV wind tunnel testing, and CFD simulation studies. The results define the main design parameters for an efficient system, and show the potential for the generation of high amounts of renewable energy with a novel and effective system suited for the built environment.

    The German system to prevent, detect and respond to illicit uses of nuclear materials and radioactive sources consists of a variety of different elements: International and national laws and regulations covering safeguards, physical protection, and import/export control; Licensing and regulatory supervision of all activities related to nuclear materials and radioactive sources, including import and export; Responsibility of the licensee to ensure compliance with licensing conditions; sanctions; Law enforcement by police, security and customs authorities; prosecution and penalties; Detection of illicitly trafficked radioactive materials through intelligence and technical means; analysis capabilities; Response arrangements for normal and for severe cases of illicit use of nuclear materials; Participation in international programmes and POC-systems. Safeguards measures have been implemented in Germany in accordance with the Non- Proliferation Treaty and with safeguards agreements based on INFCIRC/153. As Germany is a member of the European Union, the Euratom Treaty and the Euratom-Ordinance Nr. 3227/76 together with the Verification Agreement between the IAEA, the European Commission and the European Member States have led to safeguards measures jointly implemented by the IAEA and by Euratom. The relevant international law for the physical protection of nuclear material in force in Germany is the Convention on the Physical Protection of Nuclear Material. The recommendations on physical protection objectives and fundamentals and on physical protection measures specified in INFCIRC/225/Rev. 4 have been taken into account in various national regulations pertaining to the national design basis threat, the physical protection of LWR nuclear power plants, of interim spent fuel storage facilities, of facilities containing category III material, of nuclear material and radioactive waste transports by road or railway vehicles, aircraft or sea vessels; additional guidelines

    World attention is now attracted to the concept of Novel Horizontally Integrated Energy System (NHIES). In NHIES, all fossil fuels are fist converted into CO and H 2 . Potential environmental contaminants such as sulfur are removed during this process. CO turbines are mainly used to generate electric power. Combustion is performed in pure oxygen produced through air separation, making it possible to completely prevent the formation of thermal NOx. Thus, NHIES would release very little amount of such substances that would contribute to acid rain. In this system, the intermediate energy sources of CO, H 2 and O 2 are integrated horizontally. They are combined appropriately to produce a specific form of final energy source. The integration of intermediate energy sources can provide a wide variety of final energy sources, allowing any type of fossil fuel to serve as an alternative to other types of fossil fuel. Another feature of NHIES is the positive use of nuclear fuel to reduce the formation of CO 2 . Studies are under way in Japan to develop a new concept of integrated energy system. These studies are especially aimed at decreased overall efficiency and introduction of new liquid fuels that are high in conversion efficiency. Considerations are made on the final form of energy source, robust control, acid fallout, and CO 2 reduction. (Nogami, K.)

    Raw material deposits are not mobile, so globalisation has always been an important element of raw materials production and trade. Raw materials production and transport should be regarded as a large-scale system. Lower freight rates have made overseas transport possible even for bulk raw materials. If we look at Germany's raw materials supply, we find that we are customers buying from the whole world. [German] Da Lagerstaetten ortsgebunden sind, ist Globalisierung seit jeher ein wesentliches Element von Rohstoffgewinnung und handel.

    Countries vary in dimensions such as culture, language, business practices, policy-making, regulations, etc. Research shows that distances between countries concerning these dimensions affect foreign direct investment (FDI) flows. The higher the distances, the higher the difficulties for businesses, as managers’ decision-making is based on their perception of those distances. This paper analyzes the perception of distances between China and Germany by surveying Chinese managers who invested in Germany in the renewable energy (RE) sector, using Child et al.’s (2009) measure of psychic distance (PD) as a guide. The RE sector is young and highly dynamic, and the dimensions of PD are constantly changing. Mismatches in the perception of PD ex ante and ex post the decision to engage in FDI may lead to possible FDI failure. We use a five-company multiple case study to analyze if Chinese managers perceive distances in various dimensions, particularly regulation-based, and if there is a mismatch of perceptions between the pre-market and post-market entry period to investigate if managers’ perceptions change over time. Our findings lead to recommendations for practitioners and international business scholars, and policy making in the RE sector, by showing that operationalizing the PD construct should be complemented by dynamic analysis. - Highlights: • Chinese managers investing in Germany cope with distances on various dimensions • Decision-making is based on managers’ perception of those distances • This is particularly true for the RE sector and the relative regulation-based dimensions • “Prior experience” is a moderating variable and impacts managers’ perceptions. • Literature gap: perceptions vary over time and learning effects are detected.

    The President of the Deutsches Atomforum, Dr. Walter Hohlefelder, emphasized in his opening address at the 2008 Annual Nuclear Technology Conference in Hamburg that the German special approach to nuclear power utilization led straight into a dead end of energy policy. ''The outcome is foreseeable: The ambitious German goals of carbon dioxide reduction are missed, the competitiveness of the country is jeopardized, dependency on foreign energy imports rises,'' Dr. Hohlefelder stated. In view of the growing challenges in energy policy Germany had no alternative but to reassess nuclear power. The only outcome of this reappraisal could be extension of the life of nuclear power plants currently in operation. This was necessary also in order to avoid an impending gap in German electricity supply, Dr. Hohlefelder added. He invited all stakeholders to join in an open, unbiased dialog. Dr. Hohlefelder openly criticized the continued ban on research into the development of new reactors. ''A policy of this kind, a policy which bans thinking, is unacceptable in a technology-oriented, industrialized nation such as Germany.'' Nuclear power technology as a high-tech area was a unique achievement which had contributed to the prosperity of the country. The Annual Nuclear Technology Conference, which was held for the 39th time this year, is one of the biggest specialized conferences in the nuclear field with an attendance, this year, of approximately 1300 participants from more than twenty nations.

    With introduction of a diagnosis-related groups system (DRG-system) in Germany the previous duration of stay based refunding is also replaced for the radioiodine therapies by a performance oriented reimbursement system. Since the at first optional start of the DRG-system in 2003 the adaptations which take place every year should lead, up to the planned end of the convergence phase in 2009, to a transparent, fair and economical financing system of the stationary hospital service. The physician is responsible for the right and complete coding of the diagnoses and procedures, which serve as essential parameters for the determination of the diagnosis related group (DRG) of a hospital case. In the actual version of the year 2005 the DRG-system still supplies for radioiodine therapy of thyroid carcinoma some unclarity in the coding of the diagnosis, as well as clear inadequacy with the fair mapping of the therapy costs.

    This paper briefly reviews the need for renewable power generation and describes a medium-power Autonomous Renewable Energy Conversion System (ARECS), integrating conversion of wind and solar energy sources. The objectives of the paper are to extract maximum power from the proposed wind energy conversion scheme and to transfer this power and the power derived by the photovoltaic system in a high efficiency way to a local isolated load. The wind energy conversion operates at variable shaft speed yielding an improved annual energy production over constant speed systems. An induction generator (IG) has been used because of its reduced cost, robustness, absence of separate DC source for excitation, easier dismounting and maintenance. The maximum energy transfer of the wind energy is assured by a simple and reliable control strategy adjusting the stator frequency of the IG so that the power drawn is equal to the peak power production of the wind turbine at any wind speed. The presented control strategy also provides an optimal efficiency operation of the IG by applying a quadratic dependence between the IG terminal voltage and frequency V {approx} f{sup 2}. For improving the total system efficiency, high efficiency converters have been designed and implemented. The modular principle of the proposed DC/DC conversion provides the possibility for modifying the system structure depending on different conditions. The configuration of the presented ARECS and the implementation of the proposed control algorithm for optimal power transfer are fully discussed. The stability and dynamic performance as well as the different operation modes of the proposed control and the operation of the converters are illustrated and verified on an experimental prototype.

    The development of a centralised and sustainable heat supply through the construction of heat grids offers consumers numerous advantages compared to a decentralised energy supply of residential and commercial properties. Where the migration to centralised heat supply relegates fossil fuels through the long-term incorporation of sustainable renewable energy sources, the projects make an important contribution towards meeting the government's climate protection goals. Heat generation and heat sales from renewable energy sources should be ensured in the long term. In the countryside, biogas plant operators are frequently the initiators of heat grid investments, or they take on the role of supplier for the provision of low-cost CHP heat from cogeneration units. In view of the limited remuneration period under the terms of the German Renewable Energy Act, the clock is ticking for the establishment of a centralised heat supply. This paper presents the advantages and disadvantages of a centralised, sustainable heat supply and additionally considers the flexibi/isation of biogas plants in view of the construction of the heat grid and the associated infrastructure. A focus is placed on the security of supply for customers after the discontinuation of remuneration under the German Renewable Energy Act and on how a competitive heat price from alternative energy sources can continue to be ensured.

    The energy consumption issue in distributed computing systems raises various monetary, environmental and system performance concerns. Electricity consumption in the US doubled from 2000 to 2005.  From a financial and environmental standpoint, reducing the consumption of electricity is important, yet these reforms must not lead to performance degradation of the computing systems.  These contradicting constraints create a suite of complex problems that need to be resolved in order to lead to 'greener' distributed computing systems.  This book brings together a group of outsta

    1991-05-01

    The Federal German Government is pushing more entrepreneurial responsibility, more deregulation and more competition. Consequently, the option 'A' - boosting of governmental planning competence - is eliminated. To be realized is option 'C' - modernization of the law without fundamental change of its substance. Within, the meaning of option 'B' - boosting of the undertakers' and consumers' own responsibility by deregulation - it is necessary to carefully review each individual instance described in the law in order to decide whether it can be rendered superfluous by less stringent regulation of the market. With regard to ten problems, the article indicates the attitude taken by the Federal German ministry of economy in the light of talks so far held, e.g.: enlargement of the catalogue of targets by pollution abatement and careful management of resources; equal regulatory effort for electric power and gas; federally uniform approval procedure for overhead power transmission lines from 110 kV; energy-economic investments supervision etc. (HSCH).

    Basically, the solar photovoltaic power system consists of: Array of solar panels; Charge/voltage stabilizer; Blocking diode and Storage device. The storage device is a very important part of the system due to the necessity to harmonize the inevitable time shift between energy supply and demand. As energy storage, different devices can be utilized, such as hydropumping, air or other gas compression, flywheel, superconducting magnet, hydrogen generation and so on, but actually secondary (rechargeable) electrochemical cells appear to be the best storage device, due to the direct use for recharge of the d.c. current provided by the solar panels, without any intermediate step of energy transformation and its consequent loss of efficiency

    The German DRG system (G-DRG system) is required to assign medical cases with similar costs correctly into a particular group, each case within the group receiving the same amount of reimbursement. At the same time the system should allow all-inclusive reimbursement, not necessarily reflecting the exact costs of each case. These opposite goals and the so far limited calculation basis raise the question of how the G-DRG system actually processes and reimburses empirically collected in-hospital treatment data. In 2005, 112 patients were admitted to the University Eye Hospital, University of the Saarland. All patients had diabetic retinopathy and required at least one vitreoretinal procedure. Demographic and clinical data were collected by using the hospital information system and the coding software KODIP. For statistic evaluation, principal diagnoses, ancillary diagnoses and procedures were each reassigned to particular groups. Reimbursement was calculated based on the case data of the year 2005. Also, the case data were reassigned with respect to calculation of reimbursement for the years 2006 and 2007. The results were compared with federal G-DRG calculation data. Mean age of the patients was 65.8 +/- 11.1 years, length of stay in-hospital was 9.3 +/- 3.2 days. In the 66 patients requiring general anaesthesia the cumulative length of stay in the operation room was 148.4 +/- 39.5 minutes, the cumulative duration of surgery was 86.3 +/- 34.1 minutes. In the 50 patients requiring local anaesthesia the cumulative length of stay in the operation room was 137.8 +/- 51.8 minutes, the cumulative duration of surgery was 81.6 +/- 43.6 minutes. The patients had 1.9 +/- 0.8 principal diagnoses, 14.4 +/- 5.8 ancillary diagnoses and 3.4 +/- 1.6 procedures. Twenty-five of 112 patients (22.3 %) were assigned to DRG C 03Z (1), 82 of 112 patients (73.2 %) were assigned to DRG C 17Z (2). Five patients were assigned to other DRG.

    The decision of the German parliament to gradually close down nuclear power plants mainly located in the south of Germany and to support wind farms in the North Sea mud flats as the dominant regenerative energy source requires the strengthening and enlargement of the power supply system with the installation of new long distance high voltage power lines. The legally fixed dimension and formality of the actual planning process are discussed as well as the legal regulations for the protection of human health. Guided by the assessment of IARC a ''possible'' carcinogenic effect of low frequency electromagnetic fields on people living in the vicinity of high voltage power lines has to be considered. Therefore from a preventive viewpoint the minimal distance of 400 m between newly planned high voltage power lines and human settlements required by law seem justified.

The collaboration in IC was triggered by the contract between Rovno NPP (Ukraine) and Siemens (Germany) on procurement of digital emergency protection system for Unit 4. The collaboration has been realized between regulatory authorities and supporting organizations of both countries: GRS/ISTec - Germany and Nuclear Regulatory Authority and State Scientific Technical Center of Nuclear and Radiation Safety (SSTC NRS) - Ukraine. From the beginning the collaboration was intended to cover not only the single specific system, but also a great number of tasks concerned with safety assessment of digital IC systems. As a result the existing Ukrainian standards on IC assessment have been re-evaluated and supplemented by requirements concerning software-based digital IC safety systems. (authors)

    This report systematically compares, within a consistent framework, the technical and economic characteristics of energy-conserving irrigation systems with those of conventional irrigation systems and to determine total energy savings. Levelized annual costs of owning and operating both energy-conserving and conventional irrigation systems have been developed and compared for all 17 states to account for the differences in energy costs and irrigation conditions in each state. Market penetration of energy-conserving systems is assessed for those systems having lower levelized annual costs than conventional systems performing the same function. Annual energy savings were computed by matching the energy savings per system with an assumed maximum market penetration of 100 percent in those markets where the levelized annual costs of energy-conserving systems are lower than the levelized annual costs of conventional systems.

  8. An illustrative note on the system price effect of wind and solar power. The German case

    2014-01-01

    Exposing wind and solar power to the market price signal allows for cost-efficient investment decisions, as it incentivizes investors to account for the marginal value (MV el ) of renewable energy technologies. As shown by Lamont (2008), the MV el of wind and solar power units depends on their penetration level. More specifically, the MV el of wind and solar power units is a function of the respective unit's capacity factor and the covariance between its generation profile and the system marginal costs. The latter component of the MV el (i.e., the covariance) is found to decline as the wind and solar power penetration increases, displacing dispatchable power plants with higher short-run marginal costs of power production and thus reducing the system marginal costs in all generation hours. This so called 'system price effect' is analyzed in more detail in this paper. The analysis complements the work Lamont (2008) in two regards. First of all, an alternative expression for the MV el of wind and solar power units is derived, which shows that the MV el of fluctuating renewable energy technologies depends not only on their own penetration level but also on a variety of other parameters that are specific to the electricity system. Second, based on historical wholesale prices and wind and solar power generation data for Germany, a numerical 'ceteris paribus' example for Germany is presented which illustrates that the system price effect is already highly relevant for both wind and solar power generation in Germany.

    Despite evidence that a rising number of municipalities in Germany are striving for energy self-sufficiency, there is little understanding of the driving factors behind this development. We investigate economic, ecological, social and energy system related factors that drive municipalities to strive for energy self-sufficiency with a focus on electricity supply. The empirical data for this study is based on insights generated through expert interviews (N =19) with mayors, energy experts and scientists as well as a quantitative study among mayors and energy officers (N =109) of German municipalities. Results show that environmental awareness, tax revenues and greater independence from private utilities are positively related to the mayors’ attitude towards the realization of energy self-sufficiency. Furthermore, citizens, the political environment, the mayor's political power, and his/her financial resources are relevant factors for a municipality striving for energy self-sufficiency. Policymakers need to decide whether or not to support mayors in this development. For suitable policy interventions, the results suggest the importance of an integrated approach that considers a combination of identified factors. Finally, we propose a morphological box to structure different aspects of energy self-sufficiency and categorize the present study. - Highlights: • Municipalities striving for energy self-sufficiency can play a key role in the transition of the energy system. • Tax revenues and environmental awareness main drivers behind mayors’ attitude towards energy self-sufficiency. • Citizens and the political environment main influencers of mayors striving for energy self-sufficiency. • 19 expert interviews analyzed for the framework of the study based on the theory of planned behavior (TPB). • 109 mayors and energy officers participated in the quantitative main survey.

    The oil crisis of autumn 1973 was a turning point of the seventies. Citizens of industrialized countries were brought to realize their dependence on Arab imported oil the hard way. Using the example of German-French relations, the author investigates if there were instances of cooperation in energy policy, and in what concrete manner. Using historical primary energy sources, she starts by investigating the actions and political strategies of the German and French governments and also describes the search for multilateral solutions. Examples are presented to show how civil society is affected. This first systematic analysis of German-French relations shows that energy policy had great importance for the bilateral relation even though results of German-French cooperation were few and far between.

    It is well-documented that energy and energy systems have a central role in social and economic development and human welfare at all scales, from household and community to regional and national (41). Among its various welfare effects, energy is closely linked with people s health. Some of the effects of energy on health and welfare are direct. With abundant energy, more food or more frequent meals can be prepared; food can be refrigerated, increasing the types of food items that are consumed and reducing food contamination; water pumps can provide more water and eliminate the need for water storage leading to contamination or increased exposure to disease vectors such as mosquitoes or snails; water can be disinfected by boiling or using other technologies such as radiation. Other effects of energy on public health are mediated through more proximal determinants of health and disease. Abundant energy can lead to increased irrigation, agricultural productivity, and access to food and nutrition; access to energy can also increase small-scale income generation such as processing of agricultural commodities (e.g., producing refined oil from oil seeds, roasting coffee, drying and preserving fruits and meats) and production of crafts; ability to control lighting and heating allows education or economic activities to be shielded from daily or seasonal environmental constraints such as light, temperature, rainfall, or wind; time and other economic resources spent on collecting and/or transporting fuels can be used for other household needs if access to energy is facilitated; energy availability for transportation increases access to health and education facilities and allow increased economic activity by facilitating the transportation of goods and services to and from markets; energy for telecommunication technology (radio, television, telephone, or internet) provides increased access to information useful for health, education, or economic purposes; provision of energy

    Full Text Available In the last five years or so, biofuels have been given notable consideration worldwide as an alternative to fossil fuels, due to their potential to reduce greenhouse gas emissions by partial replacement of oil as a transport fuel. The production of biofuels using a sustainable approach, should consider local production of biofuels, obtained from local feedstocks and adapted to the socio-economical and environmental characteristics of the particular region where they are developed. Thus, decentralized energy from waste systems will exploit local biomass to optimize their production and consumption. Waste streams such as agricultural and wood residues, municipal solid waste, vegetable oils, and algae residues can all be integrated in energy from waste systems. An integral optimization of decentralized energy from waste systems should not be based on the optimization of each single process, but the overall optimization of the whole process. This is by obtaining optimal energy and environmental benefits, as well as collateral beneficial co-products such as soil fertilizers which will result in a higher food crop production and carbon dioxide fixation which will abate climate change.

    In liberalized, regulated energy markets, the different participants - namely producers and consumers of energy, transmission and distribution system operators as well as regulatory authorities - have partly divergent and partly convergent interests. Loads, power plants and grid operators try to maximize their own benefit in this highly complex environment accepting to act detrimentally to others. Although the relationship between the participants is mostly competitive, there are some fundamental shared interests, e.g. voltage stability, a constant system frequency or efficient energy production, transmission and distribution, which are endangered e.g. by increased injection of volatile sources in low and medium voltage grids, displacement of stabilizing bulk generation and the slowly progressing extension of the electric grid. There is a global consensus, that the resulting challenges can efficiently be faced using information and communication technologies to coordinate grid utilization and operation. The basic idea is to benefit from unused reserves by participating in deployment of system services e.g. reactive power supply to keep the voltage within certain bounds. The coordination can best be done by the grid operator. All activities of that kind are summarized under the umbrella term ''Smart Grid''. To simultaneously model the behavior and interests of different types of market participants and their convergent and divergent interests, multi-agent systems are used. They offer a perfectly fitting framework for this sort of game theory and can easily be adapted to all kinds of new challenges of electricity markets. In this work, multi-agent systems are used to either cooperatively or competitively solve problems in distribution and transmission systems. Therefore, conventional algorithms have to be modified to converge into multiple local optima using only small pieces of the entire system information. It is clearly stated, that personal

The decentralized energy systems are in the focus because it is expected that they will gain in significance in the course of restructuring and liberalisation of the energy markets and growing commitment to greenhouse gas mitigation. The subjects of the papers are the cogeneration technology in general, and specific systems for combined generation of heat, power and cold,(CHPC systems), systems for renewable energy generation, industrial energy technology, and analysis and optimization of energy systems. The report is intended to serve as a source of guidance and reference for manufacturers and operators of decentralized energy systems, for decision-making on energy policy, and for the energy industry, counselling firms and regulatory/surveillance bodies, and members of universities involved in relevant research and development work. (orig./CB) [German] Themenschwerpunkt des VDI-Berichts sind die dezentralen Energiesysteme, die im Spannungsfeld von fortschreitender Liberalisierung der Energiemaerkte und der Bemuehungen um die Reduzierung von Emissionen an Bedeutung gewinnen.

  16. Energy Efficiency in Manufacturing Systems

    CERN Document Server

    Thiede, Sebastian

    2012-01-01

    Energy consumption is of great interest to manufacturing companies. Beyond considering individual processes and machines, the perspective on process chains and factories as a whole holds major potentials for energy efficiency improvements. To exploit these potentials, dynamic interactions of different processes as well as auxiliary equipment (e.g. compressed air generation) need to be taken into account. In addition, planning and controlling manufacturing systems require  balancing technical, economic and environmental objectives. Therefore, an innovative and comprehensive methodology – with a generic energy flow-oriented manufacturing simulation environment as a core element – is developed and embedded into a step-by-step application cycle. The concept is applied in its entirety to a wide range of case studies such as aluminium die casting, weaving mills, and printed circuit board assembly in order to demonstrate the broad applicability and the benefits that can be achieved.

    The possibility of improving the thermal efficiency of energy systems from an exergy point of view is discussed. In total energy systems, we should employ multi-pass recycling consisting of thermal and chemical energies. The recycling system is supported by electrical energy, which is provided by a renewable energy source or by excess commercial electric power. This total energy system should be considered not only in one country, but all around the globe. (author). 6 figs., 4 tabs., 8 refs

  18. On the dynamics of compound bedforms in high-energy tidal channels: field observations in the German Bight and the Danish Wadden Sea

    Tidal inlets are a common feature along much of the world's coastlines. They interrupt the alongshore continuity of shoreline processes, and by being exposed to both wave and current forcing, tidal inlets belong to the morphologically most dynamic and complex coastal systems on Earth. The tidal channels in these inlets are characterized by high flow velocities and, accordingly, the channel beds are typically sandy and covered with bedforms. The bedform fields in nature are often complex systems with larger primary-bedforms superimposed by smaller secondary-bedforms (cf. Bartholdy et al., 2002). There is a considerable amount of detailed field investigations on the dynamics of primary-bedforms at various temporal scales, ranging from short- to long-term tide-related cycles to flood hydrographs to seasonality. However, Julien et al. (2002) stated that a composite analysis of primary- and secondary-bedforms is recommended for future studies on resistance to flow. Such knowledge on the behaviour of compound bedforms is still deficient. In this study, we combine the findings on the dynamics of primary- and secondary-bedform height from detailed field investigations carried out in two high-energy tidal channels during 2007 and 2008: the Knudedyb tidal inlet channel in the Danish Wadden Sea and the Innenjade tidal channel in the Jade Bay, German Bight (both survey areas being ebb-dominated). We provide process-based explanations of the bedform behaviour and present a conceptual model of compound bedform dynamics. The conducted field investigations comprised repetitive, simultaneous measurements of high-resolution swath bathymetry (using a multibeam echosounder system) and flow velocity (using an acoustic Doppler current profiler) in combination with detailed spatial mapping of bed material characteristics (from grab sampling of bed material). For an objective and discrete analysis of primary- and secondary-bedforms a modified version of the bedform tracking tool

    On 17th December 2008 the German Federal Cabinet adopted the German Strategy for Adaptation to Climate Change (DAS: Deutsche Anpassungsstrategie) (BUNDESREGIERUNG 2008). The DAS has created the framework for adapting to the consequences of climate change in Germany. First and foremost, the DAS contributes its guidelines at Federal level, to provide guidance for agents at other levels. The Strategy lays the foundation for a medium-term process. In conjunction with the individual Federal States and other groups representing various sectors of society, the Strategy provides a step-by-step assessment of the risks of climate change. Furthermore, it states the potential requirements for action, and defines the appropriate goals and potential adaptation measures to be developed and implemented in the process. The Strategy is divided into 13 action fields and two cross-sectional fields (=14+15). (1) Human health (2) Building sector (3) Water regime, water management, coastal and marine protection (4) Soil (5) Biological diversity (6) Agriculture (7) Woodland and forestry (8) Fishery (9) Energy industry (conversion, transport and supply) (10) Financial services industry (11) Transport, transport infrastructure (12) Trade and industry (13) Tourism industry (14) Spatial, regional and physical development planning (15) Civil protection. In due course, the Federal Environment Agency (UBA) will design a comprehensive set of tools to support and implement the DAS. This will be made available for download from www.anpassung.net. An integral part of this will be the 'Tatenbank' (www.tatenbank.anpassung.net), the 'Klimalotse' (www.klimalotse.anpassung.net), FISKA (special information system 'Adaptation') and an Indicator System to aid adaptation. The latter is one of the key tasks identified for the DAS. As far as the Indicator System is concerned, it has been decided to prepare a Report on Indicators for the challenges facing Germany and the

  1. An illustrative note on the system price effect of wind and solar power. The German case

    2014-07-15

    Exposing wind and solar power to the market price signal allows for cost-efficient investment decisions, as it incentivizes investors to account for the marginal value (MV{sup el}) of renewable energy technologies. As shown by Lamont (2008), the MV{sup el} of wind and solar power units depends on their penetration level. More specifically, the MV el of wind and solar power units is a function of the respective unit's capacity factor and the covariance between its generation profile and the system marginal costs. The latter component of the MV{sup el} (i.e., the covariance) is found to decline as the wind and solar power penetration increases, displacing dispatchable power plants with higher short-run marginal costs of power production and thus reducing the system marginal costs in all generation hours. This so called 'system price effect' is analyzed in more detail in this paper. The analysis complements the work Lamont (2008) in two regards. First of all, an alternative expression for the MV{sup el} of wind and solar power units is derived, which shows that the MV{sup el} of fluctuating renewable energy technologies depends not only on their own penetration level but also on a variety of other parameters that are specific to the electricity system. Second, based on historical wholesale prices and wind and solar power generation data for Germany, a numerical 'ceteris paribus' example for Germany is presented which illustrates that the system price effect is already highly relevant for both wind and solar power generation in Germany.

    Also called energy scavenging, energy harvesting captures, stores, and uses ""clean"" energy sources by employing interfaces, storage devices, and other units. Unlike conventional electric power generation systems, renewable energy harvesting does not use fossil fuels and the generation units can be decentralized, thereby significantly reducing transmission and distribution losses. But advanced technical methods must be developed to increase the efficiency of devices in harvesting energy from environmentally friendly, ""green"" resources and converting them into electrical energy.Recognizing t

    2017-12-01

    Towards meeting Paris` climate change goals, a rapid shift towards clean energy sources is needed. While the deployment of centralized solar photovoltaic (PV) power plants has been remarkable in Germany and -in the last years- also in Chile, the residential PV installations in Chile lag greatly in contrast to Germany. In fact, Chile's largest PV system until 2012 was smaller than 25 kW. And, although the recently implemented net-billing scheme has brightened this scenario, most of Chile's roofs keep being bald. Beyond the evident economic contrasts among both countries, there are many other underlying differences in public acceptance of renewable technologies. Understanding them is of both conceptual and practical importance. Here, we study the variables that determine the public acceptance of residential PV systems in Germany and Chile. We survey the positions of laypersons on the support of climate change goals, on the necessity of renewable technologies, on their auto-sustainability (how much I identify myself with being sustainable), and on their auto-effectiveness (do I believe that my behavior has impact on global targets). The sample is further characterized by socioeconomic status, knowledge and experience and proximity to solar systems, esthetic perception of the systems, security of the neighborhood and house ownership, willingness of installing solar systems, and trust in the technology. We identify the main factors via data correlation analysis. From our findings, actions to improve the acceptance and literacy of solar technologies in Chile can be derived.

He comments the German energy mix for 2010 in terms of electricity production per origin (nuclear, coal and lignite, gas, oil, wind, solar photovoltaic, other renewable sources) and of installed capacities per origin. He notices that gas and coal still have a major weight in this mix, and discusses the content of a scenario based 100 per cent renewable energies as it has been studied by the Fraunhofer Institute, notably in terms of production level and of costs

    Introduced in autumn 2012 and updated twice a year since, the German 2020 Energy Transition Index (EWI) shows its first signs ever of a favourable trend. At last the indicators have got moving, even though one can hardly speak of a breakthrough yet. In spite of the positive trend, especially in regard to electricity consumption and the rate of newly installed offshore wind power capacity, the envisaged goals are still a long way off. This holds particularly for major indicators such as CO{sub 2} emissions and price levels of household and industrial electricity.

  11. Integrating renewables into energy systems

    International Nuclear Information System (INIS)

    1999-03-01

    An analysis of renewable energy schemes was undertaken via case studies in China, India, Indonesia, Kenya, South Africa, Thailand and Zimbabwe, that provided an insight into the application of best practice for overcoming market, technical and financial barriers to the establishment of the sustainable markets required for the large-scale deployment of renewable energy technologies. The project showed clearly the need to select and target interventions according to the context. Lessons were extracted against a number of themes, as well as against the various technologies analysed and simple guides to the principles of best practice were derived under the following headings:- experience of gaining access to (micro) finance; the technical and non-technical issues raised when small, typically independent, generators seek access to central electricity grid systems; how to best undertake awareness raising and dissemination activities; promoting, building and operating biogas systems; promoting, building and operating solar (photovoltaic) home systems; promoting, building and operating grid connected wind power; promoting, building and operating solar hot water systems; promoting agricultural cogeneration using crop residues.

    Crystalline products of sodium germanate glasses system with composition from 10 mol% to 50 mol% Na 2 O have been investigated using 23 Na magic angle spinning (MAS) nuclear magnetic resonance (NMR) spectroscopy and x-ray diffraction (XRD). Fitting of the 23 Na NMR spectra of the crystalline phases concerning different crystallographically sodium atom in sodium germanate system are reasonably reproducible as observed by the spectra obtained. The line shape simulations of the 23 Na NMR spectra yielded NMR quadrupolar parameters such as nuclear quadrupole coupling constants (C Q ), asymmetry parameters (η), and isotropic chemical shifts (δ i ). 23 Na NMR isotropic chemical shift may also provide further information on the structural environment of the sodium atom. A simple correlation between structure and NMR parameters to be tested can be used to probe the structure of sodium germanate glasses. The experimental 23 Na chemical shifts correlate well with an empirical shift parameter based on the total oxygen-cation bond valence and Na-O distances of all oxygen atoms in the first coordination sphere of the sodium cation. In this study the different phases in the sodium germanate system were identified. These results show that 23 Na NMR can provide examples of the types of structural information for sodium germanate system. (Author)

    The computer program SYSOPT, intended as a tool for optimizing the subsystem sizing, performance, and economics of integrated wind and solar energy systems, is presented. The modular structure of the methodology additionally allows simulations when the solar subsystems are combined with conventional technologies, e.g., a utility grid. Hourly energy/mass flow balances are computed for interconnection points, yielding optimized sizing and time-dependent operation of various subsystems. The program requires meteorological data, such as insolation, diurnal and seasonal variations, and wind speed at the hub height of a wind turbine, all of which can be taken from simulations like the TRNSYS program. Examples are provided for optimization of a solar-powered (wind turbine and parabolic trough-Rankine generator) desalinization plant, and a design analysis for a solar powered greenhouse.

    2008-03-01

    A total of 452 samples from hot water systems of randomly selected single family residences in the suburbs of two German cities were analysed for the occurrence of Legionella. Technical data were documented using a standardized questionnaire to evaluate possible factors promoting the growth of the bacterium in these small plumbing systems. All houses were supplied with treated groundwater from public water works. Drinking water quality was within the limits specified in the German regulations for drinking water and the water was not chlorinated. The results showed that plumbing systems in private houses that provided hot water from instantaneous water heaters were free of Legionella compared with a prevalence of 12% in houses with storage tanks and recirculating hot water where maximum counts of Legionella reached 100,000 CFU/100ml. The presence of L. pneumophila accounted for 93.9% of all Legionella positive specimens of which 71.8% belonged to serogroup 1. The volume of the storage tank, interrupting circulation for several hours daily and intermittently raising hot water temperatures to >60 degrees C had no influence on Legionella counts. Plumbing systems with copper pipes were more frequently contaminated than those made of synthetic materials or galvanized steel. An inhibitory effect due to copper was not present. Newly constructed systems (water preparation had a marked influence. More than 50% of all houses using district heating systems were colonized by Legionella. Their significantly lower hot water temperature is thought to be the key factor leading to intensified growth of Legionella. Although hot water systems using solar energy to supplement conventional hot water supplies operate at temperatures 3 degrees C lower than conventional systems, this technique does not seem to promote proliferation of the bacterium. Our data show convincingly that the temperature of the hot water is probably the most important or perhaps the only determinant factor for

  17. Advanced Energy Efficient Roof System

    2008-09-30

    Energy consumption in buildings represents 40 percent of primary U.S. energy consumption, split almost equally between residential (22%) and commercial (18%) buildings.1 Space heating (31%) and cooling (12%) account for approximately 9 quadrillion Btu. Improvements in the building envelope can have a significant impact on reducing energy consumption. Thermal losses (or gains) from the roof make up 14 percent of the building component energy load. Infiltration through the building envelope, including the roof, accounts for an additional 28 percent of the heating loads and 16 percent of the cooling loads. These figures provide a strong incentive to develop and implement more energy efficient roof systems. The roof is perhaps the most challenging component of the building envelope to change for many reasons. The engineered roof truss, which has been around since 1956, is relatively low cost and is the industry standard. The roof has multiple functions. A typical wood frame home lasts a long time. Building codes vary across the country. Customer and trade acceptance of new building products and materials may impede market penetration. The energy savings of a new roof system must be balanced with other requirements such as first and life-cycle costs, durability, appearance, and ease of construction. Conventional residential roof construction utilizes closely spaced roof trusses supporting a layer of sheathing and roofing materials. Gypsum board is typically attached to the lower chord of the trusses forming the finished ceiling for the occupied space. Often in warmer climates, the HVAC system and ducts are placed in the unconditioned and otherwise unusable attic. High temperature differentials and leaky ducts result in thermal losses. Penetrations through the ceilings are notoriously difficult to seal and lead to moisture and air infiltration. These issues all contribute to greater energy use and have led builders to consider construction of a conditioned attic. The

    2013-02-15

    In this thesis, we consider the control of two different industrial applications that belong at either end of the electricity grid; a power consumer in the form of a commercial refrigeration system, and wind turbines for power production. Our primary studies deal with economic model predictive control of a commercial multi-zone refrigeration system, consisting of several cooling units that share a common compressor, and is used to cool multiple areas or rooms, e.g., in supermarkets. For control of the commercial refrigeration application as well as the wind turbine application, we propose an economic optimizing model predictive controller, economic MPC. Our investigations are primarily concerned with: 1) modeling of the applications to suit the chosen control framework; 2) formulating the MPC controller laws to overcome challenges introduced by the industrial applications, and defining economic objectives that reect the real physics of the systems as well as our control objectives; 3) solving the involved, non-trivial optimization problems eciently in real-time; 4) demonstrating the feasibility and potential of the proposed methods by extensive simulation and comparison with existing control methods and evaluation of data from systems in actual operation. We demonstrate, i.a., substantial cost savings, on the order of 30 %, compared to a standard thermostat-based supermarket refrigeration system and show how our methods exhibit sophisticated demand response to real-time variations in electricity prices. Violations of the temperature ranges can be kept at a very low frequency of occurrence inspite of the presence of uncertainty. For the power output from wind turbines, ramp rates, as low a 3 % of the rated power per minute, can be effectively ensured with the use of energy storage and we show how the active use of rotor inertia as an additional energy storage can reduce the needed storage capacity by up to 30 % without reducing the power output.

    2012-12-10

    Energy Return On Investment (EROI) is an important figure of merit for assessing the viability of energy alternatives. Too often comparisons of energy systems use efficiency when EROI would be more appropriate. For geothermal electric power generation, EROI is determined by the electricity delivered to the consumer compared to the energy consumed to construct, operate, and decommission the facility. Critical factors in determining the EROI of Engineered Geothermal Systems (EGS) are examined in this work. These include the input energy embodied into the system. Embodied energy includes the energy contained in the materials, as well as, that consumed in each stage of manufacturing from mining the raw materials to assembling the finished system. Also critical are the system boundaries and value of the energy heat is not as valuable as electrical energy. The EROI of an EGS depends upon a number of factors that are currently unknown, for example what will be typical EGS well productivity, as well as, reservoir depth, temperature, and temperature decline rate. Thus the approach developed is to consider these factors as parameters determining EROI as a function of number of wells needed. Since the energy needed to construct a geothermal well is a function of depth, results are provided as a function of well depth. Parametric determination of EGS EROI is calculated using existing information on EGS and US Department of Energy (DOE) targets and is compared to the minimum EROI an energy production system should have to be an asset rather than a liability.

In Germany, successive governments have specified their ideas on sustainable development and the related energy system. Detailed objectives make the vision of the Energiewende – the transformation of the energy sector – more concrete. Many Germans hope that the country sets a positive example for other nations whose energy systems also heavily rely on fossil fuels. A glance at the historical dimensions of this transformation shows that the origins of German energy objectives lie more than thirty years in the past. The realization of these goals has not been free from tensions and conflicts. This article aims at explaining Germany's pioneering role in the promotion of an energy system largely built on renewable energy sources by disclosing the drivers that have successively led to the Energiewende. To reveal these drivers, the historical emergence of energy politics in Germany was analyzed especially with respect to path dependencies and discourses (and their underlying power relations) as well as exogenous events that have enabled significant shifts in the political energy strategy of Germany. - Highlights: • Analysis of key drivers of the German Energiewende. • Enabled by special constellation of political developments and external incidents. • Resulted in changing power constellations and discourse dynamics. • Contended political process spurred strong economic leaders to support renewables. • Their impact drove all political parties towards nuclear phase-out and Energiewende.

    Several years ago when the author was working in the chemicals division of a paper company in Instrumentation and Controls, one experience had a lasting impact on his work approach which is systems approach. The maintenance manager told the author that a very important piece of boiler instrument of the power plant had broken down and delivery of the replacement needed to be expedited. The instrument was ordered over the phone in another city. The purchase order was personally delivered at the supplier's office and arrangements were made so the instrument was put on the next flight. A week later the maintenance manager indicated that the particular instrument still had not arrived in the plant and he could not run the power plant. Thus the company incurred substantial losses. Further inquiries showed that the instrument did indeed arrive at the plant stores on time. But, in the absence of any instructions thereon, the instrument was not delivered to the power plant. The sense of urgency was lost in the existing delivery process. In other words, the process or system failed. The whole process from requisitioning to delivery of ordered items was analyzed and corrective procedures were incorporated to prevent future repetitions. This brings up the subject of systems approach in engineering management in general and energy management in particular. This involves defining an objective and designing a system for an effective way of getting there

  12. SMES for wind energy systems

    simulation results the utility of SMES in voltage sag mitigation for momentary interruptions. The 1MJ SMES mitigates voltage sags for a useful duration ~50 seconds. In conclusion (Chapter 7), we believe that in this dissertation, we have documented the design of SMES for both momentary and sustained interruptions in wind turbines. We have put forth some novel and relevant hypotheses, developed and performed suitable simulation studies to validate these hypotheses. By doing so, we have been able to expand our knowledge in our quest to grasp the underlying mechanisms of storage systems in wind energy integration. Although the resulting analysis has allowed us to gain valuable insight, we feel that it is only the tip of the iceberg, and that many yet unknown discoveries are to be made. We remain hopeful that the future of SMES for wind energy will only look brighter from here onward. (Abstract shortened by UMI.).

    Investments in renewable energy are more attractive due to the contribution of two key federal tax incentives. The investment tax credit (ITC) and the Modified Accelerated Cost Recovery System (MACRS) depreciation deduction may apply to energy storage systems such as batteries depending on who owns the battery and how the battery is used. The guidelines in this fact sheet apply to energy storage systems installed at the same time as the renewable energy system.

  16. An Optimal Power and Energy Management by Hybrid Energy Storage Systems in Microgrids

    Full Text Available A novel optimal power and energy management (OPEM for centralized hybrid energy storage systems (HESS in microgrids is presented in this paper. The proposed OPEM aims at providing multiple grid services by suitably exploiting the different power/energy features of electrochemical batteries (B and supercapacitors (S. The first part of the paper focuses on the design and analysis of the proposed OPEM, by highlighting the advantages of employing hand-designed solutions based on Pontryagin’s minimum principle rather than resorting to pre-defined optimization tools. Particularly, the B power profile is synthesized optimally over a given time horizon in order to provide both peak shaving and reduced grid energy buffering, while S is employed in order to compensate for short-term forecasting errors and to prevent B from handling sudden and high-frequency power fluctuations. Both the B and S power profiles are computed in real-time in order to benefit from more accurate forecasting, as well as to support each other. Then, the effectiveness of the proposed OPEM is tested through numerical simulations, which have been carried out based on real data from the German island of Borkum. Particularly, an extensive and detailed performance analysis is performed by comparing OPEM with a frequency-based management strategy (FBM in order to highlight the superior performance achievable by the proposed OPEM in terms of both power and energy management and HESS exploitation.

    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.

    In Germany, the Association for Radiation Protection (member of IRPA) defined a new standard for the monitoring of workers occupationally exposed to radioactive material. During the last two years this draft has been accepted by the German government in the form of three directives. The purpose of our approach was the installation of a system defining clear criteria for the necessity of regular and special monitoring programs, giving directives for monitoring programs ensuring that dose assessments are as reliable as necessary with the lowest possible expenses, standardizing as far as possible the procedures of dose assessments, and guaranteeing the necessary quality standards. The most important features of these regulations will be discussed in this contribution and their application will be exemplified for the specially difficult monitoring of thorium intakes.

    This paper outlines the background, development, and assessment of a prototype enterprise energy information system (EEIS) that supports strategic energy-management by providing comprehensive energy monitoring and targeting, integrating with energy modelling software and enterprise business databases, and supporting measurement and verification (M and V). The EEIS prototype system was developed and assessed in an industrial site and a third-level education institution with colleges throughout Dublin. The industrial site provided the opportunity for the EEIS to meet the requirements of a large energy intensive site, and to integrate with energy modelling software. The higher education establishment accommodated the development of a networked energy-information system. (author)
