    Futurist writing about technology emerged in the late 19th century at the same time as new kinds of electrical technology were making utopian futures seem practically attainable. Electrical writers and novelists alike thus borrowed from the popular "science" fiction of Jules Verne, Edward Bellamy and others to try to create self-fulfilling prophecies of a future in which electrical gadgets and machines met all major practical needs of civilization. To the extent that many parts of our world are populated by the hardware that they forecast, they succeeded in their goal.

    Where will America's future electricity supply come from? According to Vice President Cheney's energy task force, the U.S. needs to build about one 1 GW generating facilty a week in perpetuity.^(1) What sort of facilities will they be? Can the economy sustain such growth? Are there other possibilities? One possibility that strikes a chord with physicists is conservation as a source of energy. In this regard, Vice President Cheney famously said that conservation is``a sign of personal virtue, but it is not a sufficient basis---all by itself---for a sound, comprehensive energy policy,''^(2) echoing the Ayn Rand Instituite's view that ``Conservation is not a long- or short-term solution to the energy crisis. Conservation is the un-American idea of resigning oneself to doing with less.''^(3) This poster will explore the possible energy futures, their advantages and disadvantages, with and without conservation. 1.

    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.

    While some agent-based models have been developed for analyzing the German electricity market, there has been little research done on the emerging issue of intra-German congestion and its effects on the bidding behavior of generator agents. Yet, studies of other markets have shown that transmission grid constraints considerably affect strategic behavior in electricity markets. In this paper, the implications of transmission constraints on power markets are analyzed for the case of Germany. Market splitting is applied in the case of congestion in the grid. For this purpose, the agent-based modeling of electricity systems (AMES) market package developed by Sun and Tesfatsion is modified to fit the German context, including a detailed representation of the German high-voltage grid and its interconnections. Implications of transmission constraints on prices and social welfare are analyzed for scenarios that include strategic behavior of market participants and high wind power generation. It can be shown that strategic behavior and transmission constraints are inter-related and may pose severe problems in the future German electricity market. (author)

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

    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.

    The Renewable Electricity Futures (RE Futures) Study investigated the challenges and impacts of achieving very high renewable electricity generation levels in the contiguous United States by 2050. The analysis focused on the sufficiency of the geographically diverse U.S. renewable resources to meet electricity demand over future decades, the hourly operational characteristics of the U.S. grid with high levels of variable wind and solar generation, and the potential implications of deploying high levels of renewables in the future. RE Futures focused on technical aspects of high penetration of renewable electricity; it did not focus on how to achieve such a future through policy or other measures. Given the inherent uncertainties involved with analyzing alternative long-term energy futures as well as the multiple pathways that might be taken to achieve higher levels of renewable electricity supply, RE Futures explored a range of scenarios to investigate and compare the impacts of renewable electricity penetration levels (30%-90%), future technology performance improvements, potential constraints to renewable electricity development, and future electricity demand growth assumptions. RE Futures was led by the National Renewable Energy Laboratory (NREL) and the Massachusetts Institute of Technology (MIT).

    The Renewable Electricity Futures Study (RE Futures) provides an analysis of the grid integration opportunities, challenges, and implications of high levels of renewable electricity generation for the U.S. electric system. The study is not a market or policy assessment. Rather, RE Futures examines renewable energy resources and many technical issues related to the operability of the U.S. electricity grid, and provides initial answers to important questions about the integration of high penetrations of renewable electricity technologies from a national perspective. RE Futures results indicate that a future U.S. electricity system that is largely powered by renewable sources is possible and that further work is warranted to investigate this clean generation pathway.

  9. Emissions trading and innovation in the German electricity industry

    Cames, Martin

    2010-07-01

    One major objective of the introduction of emissions trading in the European Union was to promote innovation towards mitigating climate change. Focusing on the German electricity industry, the extent to which this objective has been achieved up to now and how the design of the trading scheme could be improved towards achieving the intended objective shall be analyzed in this thesis. These questions are tackled in the thesis from a theoretical and an empirical perspective. The theoretical analysis was largely based on neoclassical environmental economics by using an algebraic model which allowed for comparison of the relevant companies' profits under various configurations of the analyzed design options. The empirical analysis was grounded on two surveys of the electricity industry - one before the start of emissions trading, the other after two and a half years of experience - which enabled identification of the concrete changes in the companies' perceptions and attitudes towards innovation due to the introduction of emissions trading. The analysis reveals some indications that the instrument has basically functioned as originally intended although it has certainly not yet developed its full potential in terms of promoting innovation towards a more climate friendly electricity system. From an environmental innovation perspective the following improvements are essential: (1) Closure provisions should be abolished as soon as possible because they basically extend the lifetime of old installations and thus rather delay innovation. (2) Fuel-specific allocation to new entrants should also be abandoned since it eliminates - at least partly - the incentives to shift investments towards technologies which use more carbon friendly fuels such as natural gas or biomass. (3) Introducing full auctioning for the electricity industry would remedy both of the above-mentioned weaknesses and at the same time eliminate the windfall profit generated by free allocation of

    Electricity resource planning is the process of identifying longer-term investments to meet electricity reliability requirements and public policy goals at a reasonable cost. Resource planning processes provide a forum for regulators, electric utilities, and electricity industry stakeholders to evaluate the economic, environmental, and social benefits and costs of different investment options. By facilitating a discussion on future goals, challenges and strategies, resource planning processes often play an important role in shaping utility business decisions. Resource planning emerged more than three decades ago in an era of transition, where declining electricity demand and rising costs spurred fundamental changes in electricity industry regulation and structure. Despite significant changes in the industry, resource planning continues to play an important role in supporting investment decision making. Over the next two decades, the electricity industry will again undergo a period of transition, driven by technological change, shifting customer preferences and public policy goals. This transition will bring about a gradual paradigm shift in resource planning, requiring changes in scope, approaches and methods. Even as it changes, resource planning will continue to be a central feature of the electricity industry. Its functions — ensuring the reliability of high voltage (“bulk”) power systems, enabling oversight of regulated utilities and facilitating low-cost compliance with public policy goals — are likely to grow in importance as the electricity industry enters a new period of technological, economic and regulatory change. This report examines the future of electricity resource planning in the context of a changing electricity industry. The report examines emerging issues and evolving practices in five key areas that will shape the future of resource planning: (1) central-scale generation, (2) distributed generation, (3) demand-side resources, (4

    Increased competition in bulk power and retail electricity markets is likely to lower electricity prices, but will also result in greater price volatility as the industry moves away from administratively determined, cost-based rates and encourages market-driven prices. Price volatility introduces new risks for generators, consumers, and marketers. Electricity futures and other derivatives can help each of these market participants manage, or hedge, price risks in a competitive electricity market. Futures contracts are legally binding and negotiable contracts that call for the future delivery of a commodity. In most cases, physical delivery does not take place, and the futures contract is closed by buying or selling a futures contract on or near the delivery date. Other electric rate derivatives include options, price swaps, basis swaps, and forward contracts. This report is intended as a primer for public utility commissioners and their staff on futures and other financial instruments used to manage price risks. The report also explores some of the difficult choices facing regulators as they attempt to develop policies in this area.

    To meet and adapt to the current and future trends and issues in technology and society, the science committee of The German Academic Society for Production Engineering (WGP) continues to define future topics for production technology. These themes represent not only the key focus for the scientific work of the WGP, but also the central themes of the first annual conference in June 2011, whose paper is publically available in this volume. Such themes, including electric mobility, medical technology, lightweight construction, and resource efficiency, as well as mass production ability have all been identified as future, large-scale, and long-term drivers of change. Future trends influence changes sustainably and fundamentally; they permeate society, technology, economics, and value systems and have an effect in virtually all areas of life. The WGP has, as part of its research, established for itself the goal of not only observing these emerging changes, but also of supervising and influencing their development...

    Patient participation within the German healthcare system is described at three different levels: the macro level as active patient influence on the regulation of medical care, the meso level in terms of institutions enhancing patient information and counselling, and the micro level focusing on the actual treatment decision-making process in the medical encounter. The main focus of the present publication is on the health care system-specific influences on patient participation in medical decision-making and on the current state of research and implementation of shared decision-making in Germany. We describe institutions promoting patient involvement, their aims and initiatives as well as recent changes in German legislation. Against the background of German health politics' endorsement of patient participation the German Ministry of Health funded a research consortium with shared decision-making intervention projects in various disease areas. The present state of the intervention projects' results is outlined as well as subsequently funded transfer projects and future perspectives of research grants. Supported by health politics and the utilisation of scientific evidence shared decision-making's transfer into practice is considered to be relevant to the German health care system.

    Within the German joint research project "concepts for future gravity satellite missions", funded by the Geotechnologies programme of the German Federal Ministry of Education and Research, options and concepts for future satellite missions for precise (time-variable) gravity field recovery are investigated. The project team is composed of members from science and industry, bringing together experts in geodesy, satellite systems, metrology, sensor technology and control systems. The majority of team members already contributed to former gravity missions. The composition of the team guarantees that not only geodetic aspects and objectives are investigated, but also technological and financial constraints are considered. Conversely, satellite, sensor and system concepts are developed and improved in a direct exchange with geodetic and scientific claims. The project aims to develop concepts for both near and mid-term future satellite missions, taking into account e.g. advanced satellite formations and constellations, improved orbit design, innovative metrology and sensor systems and advances in satellite systems.

    of new concepts to broaden the product portfolio in coming years). The second topic outlines the most likely development of liberalized electricity markets in various regions worldwide. It will be emphasized that in such markets the future prices for electricity will more and more reflect the different cost for bulk and peak power production. This will not only happen for industrial electricity customers - as already today in many countries - but also for private households. The third topic summarizes the existing data and facts by correlating peak power demand and prices traded in various stock exchange markets with delivered PV kWh. It will be shown that a high degree of correlation is existent. Combining the three topics and postulating reverse net metering the competitiveness of PV solar electricity as described is most likely to occur. The described price decrease of modules will also have a very positive impact on off-grid rural applications, mainly in 3rd world countries. It will be shown that this is strongly advanced due to the development of mini-grids starting from solar home systems - with mini grids looking very similar to on-grid applications in weak grid areas of nowadays electricity network.

    The paper describes the technical status and presents new concepts, models and approaches for the technical assistance of large scale wind power integration into the electrical energy supply system in Germany. It shows the technical and economic problems with the integration of high penetration of wind power plant in the network and the total electrical system. After an analysis of the effects of increased wind power generation on system planning and grid operation, we discuss innovative operational control concepts for large (offshore) wind farms. These concepts will provide a multitude of new possibilities to enable simple, flexible and undisturbed reaction to the demands of participants (wind farm operators, grid operators). These operational control strategies are mainly based on ISETs successful employed wind power prediction tools, operated by all German TSO's, and will enable energy and power control, as well as the provision of reactive power, in order to achieve comparable properties to conventional power plant types.

The analysis focused on the sufficiency of the geographically diverse U.S. renewable resources to meet electricity demand over future decades, the hourly operational characteristics of the U.S. grid with high levels of variable wind and solar generation, and the potential implications of deploying high levels of renewables in the future. RE Futures focused on technical aspects of high penetration of renewable electricity; it did not focus on how to achieve such a future through policy or other measures. Given the inherent uncertainties involved with analyzing alternative long-term energy futures as well as the multiple pathways that might be taken to achieve higher levels of renewable electricity supply, RE Futures explored a range of scenarios to investigate and compare the impacts of renewable electricity penetration levels (30%–90%), future technology performance improvements, potential constraints to renewable electricity development, and future electricity demand growth assumptions. RE Futures was led by the National Renewable Energy Laboratory (NREL) and the Massachusetts Institute of Technology (MIT).

    The development of the common French-German safety approach was accomplished on three working levels: the technical safety organisations GRS and IPSN provided the technical basis, the advisory groups GPR and RSK developed common recommendations, and the authorities BMU and DSIN adopted and issued the recommendations. The general safety approach issued in May 1993 contains safety objectives, general principles and some technical principles for future PWRs. Based on this general approach, more detailed recommendations have been developed in 1994 on key issues. The following period from 1995 on was characterised by a further refinement of the recommendations and the treatment of some new subjects such as digital I and C, man-machine-interface and core design.

    2015-01-01

    Use of high-power solar arrays, at power levels ranging from approximately 500 KW to several megawatts, has been proposed for a solar-electric propulsion (SEP) demonstration mission, using a photovoltaic array to provide energy to a high-power xenon-fueled engine. One of the proposed applications of the high-power SEP technology is a mission to rendezvous with an asteroid and move it into lunar orbit for human exploration, the Asteroid Retrieval mission. The Solar Electric Propulsion project is dedicated to developing critical technologies to enable trips to further away destinations such as Mars or asteroids. NASA needs to reduce the cost of these ambitious exploration missions. High power and high efficiency SEP systems will require much less propellant to meet those requirements.

    Planning for sustainable mobility is a complex and demanding task and the knowledge of how to trade off multiple, often conflicting, goals is not entirely clear. One of the most contentious and confounding issues has been, and continues to be, the place of the automobile within the sustainable...... mobility paradigm. The recent emergence of strong policy and planning support for the introduction of electric vehicles raises knotty questions as to whether or not this development will be complementary to or conflicting with other sustainable mobility planning goals, such as compact cities, restrictions...... on automobiles, promotion of walking and biking, and support for public transport. The results of a recent pilot study conducted in the Reykjavik city region suggest that electric vehicles may represent a continuation of the dominant transport engineering approach and may in fact draw scarce financial...

    The paper presents data and a methodology to allow preliminary definition of electric propulsion systems. The elements comprising the thrust system are described parametrically. As an example, thruster performance is presented as a function of specific impulse and propellant type. Two power management and control (PMAC) approaches are considered to illustrate the use of the methodology. Power source characteristics are disregarded in the system description. One PMAC concept assumes a dc power input to the thrust system and all thruster power conditioned in a conventional manner; the other PMAC approach assumes an ac power source.

    Brookhaven National Laboratory established a new technology for load forecasting for the Long Island Lighting Company and prepared an independent forecast of the demand for electricity in the LILCO area. The method includes: demand for electricity placed in a total energy perspective so that substitutions between electricity and other fuels can be examined; assessment of the impact of conservation, new technology, gas curtailment, and other factors upon demand for electricity; and construction of the probability distribution of the demand for electricity. A detailed analysis of changing levels of demand for electricity, and other fuels, associated with these new developments is founded upon a disaggregated end-use characterization of energy utilization, including space heat, lighting, process energy, etc., coupled to basic driving forces for future demand, namely: population, housing mix, and economic growth in the region. The range of future events covers conservation, heat pumps, solar systems, storage resistance heaters, electric vehicles, extension of electrified rail, total energy systems, and gas curtailment. Based upon cost and other elements of the competition between technologies, BNL assessed the likelihood of these future developments. An optimistic view toward conservation leads to ''low'' demand for electricity, whereas rapid development of new technologies suggests ''high'' demand. (MCW)

    2008-07-01

    This comprehensive final report for the Swiss Federal Office of Energy (SFOE) reviews work done on the development of new power transmission planning tools for restructured power networks. These are needed in order to face the challenges that arise due to economic, environmental and social issues. The integration of transmission, generation and energy policy planning in order to support a common strategy with respect to sustainable electricity networks is discussed. In the first phase of the project the main focus was placed on the definition of criteria and inputs that are most likely to affect sustainable transmission expansion plans. Models, concepts, and methods developed in order to study the impact of the internalisation of external costs in power production are examined. To consider external costs in the planning process, a concurrent software tool has been implemented that is capable of studying possible development scenarios. The report examines a concept that has been developed to identify congested transmission lines or corridors and evaluates the dependencies between the various market participants. The paper includes a set of three appendices that include a paper on the 28{sup th} USAEE North American conference, an abstract from Powertech 2009 and an SFOE report from July 2008.

    2011-03-15

    The transformation process from conventional electricity production to a sustainable power generation system based on renewable energy confronts market protagonists and lawmakers with huge technical and economic challenges. The rapid proliferation of wind power and photovoltaic plants in particular will raise electricity price volatility and require large investments in the expansion of transmission and distribution networks. It will also place high demands on the flexibility of the remaining electricity network, which will have to smoothen both the long and short-term fluctuations in supply from wind and photovoltaic energy. In view of the growing signs of delay in network expansion, the political leadership has taken to welcoming electricity storages as the ultimate solution to numerous challenges, as we read for example in the Energy Concept of the German Federal Government. While there may be reason for optimism, it is equally right to critically question the role that electricity storages might realistically play in the future given the need for reasonable price levels.

    This report offers perspectives on the future of the electric utility industry. These perspectives will be used in further research to assess the prospects for Integrated Resource Planning (IRP). The perspectives are developed first by examining economic, political and regulatory, societal, technological, and environmental trends that are (1) national and global in scope and (2) directly related to the electric utility industry. Major national and global trends include increasing global economic competition, increasing political and ethnic strife, rapidly changing technologies, and increasing worldwide concern about the environment. Major trends in the utility industry include increasing competition in generation; changing patterns of electricity demand; increasing use of information technology to control power systems; and increasing implementation of environmental controls. Ways in which the national and global trends may directly affect the utility industry are also explored. The trends are used to construct three global and national scenarios- ``business as usual,`` ``technotopia future,`` and ``fortress state`` -and three electric utility scenarios- ``frozen in headlights,`` ``megaelectric,`` and ``discomania.`` The scenarios are designed to be thought provoking descriptions of potential futures, not predictions of the future, although three key variables are identified that will have significant impacts on which future evolves-global climate change, utility technologies, and competition. While emphasis needs to be placed on understanding the electric utility scenarios, the interactions between the two sets of scenarios is also of interest.

  1. Long range thermal weapon sights for the German future infantryman program IdZ

    In December 2004 AIM started the series production of the HuntIR long range thermal weapon sight. The sight is fielded in the Germany Future Infantryman (IdZ) basic system and since that time in continuous service in various out of area missions with German participation. For very long identification ranges >1500m cooled technology still outperforms uncooled sights, even with respect to smaller size and lower weight because the typical F/1 design of uncooled systems overcompensates cooler weight for focal length >175mm. The HuntIR sight is therefore based on a cooled MWIR detection module for long range battlefield surveillance and target engagement. The device specifically is a perfect match to state of the art small arms like 0.50 cal sniper rifles or crew served weapons like the 40mm high velocity grenade machine gun (GMG) which provide engagement ranges >1500m and need an adequate sight performance beyond that. A recent modification of HuntIR was done to provide a wider field of view for improved situation awareness in urban operations and specifically to allow the engagement of the 40mm GMG in ranges between 250-1200m. The qualification tests of the sight by the German infantry were successfully completed mid 2006. To match the demand of the follow-up program IdZ-ES additional components have to be integrated. Most important are a laser range finder (LRF), 3 axis digital magnetic compass (DMC) and a wireless data link. LRF and DMC together with a highly sophisticated fire control computer provide improved first round hit probability, the DMC additionally improves the fire control in any case of steep trajectories or for pronounced ballistic trajectories to avoid any need to precisely level the GMG. This new sight is done under the brand name RangIR. An important additional feature is the interface for air burst ammunition (ABM). The optical distance is measured by the LRF, the fire control computer accurately evaluates the trajectory under the given angle

    Waste electrical and electronic equipment is a complex waste stream and treatment options that work for one waste category or product may not be appropriate for others. A comprehensive case study has been performed for plastic-rich fractions that are treated in German dismantling centres. Plastics from TVs, monitors and printers and small household appliances have been characterised extensively. Based on the characterisation results, state-of-the-art treatment technologies have been combined to design an optimised recycling and upgrade process for each input fraction. High-impact polystyrene from TV casings that complies with the European directive on the restriction of hazardous substances (RoHS) was produced by applying continuous density separation with yields of about 60%. Valuable acrylonitrile butadiene styrene/polycarbonate can be extracted from monitor and printer casings by near-infrared-based sorting. Polyolefins and/or a halogen-free fraction of mixed styrenics can be sorted out by density separation from monitors and printers and small household appliances. Emerging separation technologies are discussed to improve recycling results. © The Author(s) 2015.

    We have developed an analytic platform to analyze the electricity options, costs, and impacts for Kosovo, a nation that is a critical part of the debate over centralized versus distributed electricity generation and the role of fossil fuels versus cleaner electricity options to meet growing demands for power. We find that a range of alternatives exists to meet present supply constraints all at a lower cost than constructing a proposed 600 MW coal plant. The options include energy efficiency measures, combinations of solar PV, wind, hydropower, and biomass, and the introduction of natural gas. A 30 EUR ton-1 shadow price on CO2 increases costs of coal generation by at least 330 million EUR. The results indicate that financing a new coal plant is the most expensive pathway to meet future electricity demand.

    Public support schemes for electricity from renewable energy sources (RES-E) are undergoing a period of change. Two interrelated processes can be discerned at both the EU and member state (MS) levels. On the one hand, the RES-E Directive sets targets for consumption of renewable electricity for the year 2010 and opens the possibility that the European Commission sets a community support framework for RES-E promotion in the future. On the other hand, different types of support scheme have been and are used by countries in order to promote the deployment of renewable electricity. A move from tendering/bidding systems and feed-in tariffs to tradable green certificates can be observed in some MSs. This move may take place in the future in some other MSs while others will certainly continue to rely on their current scheme. This paper provides an overview and assessment of the instruments currently used to promote renewable electricity in Europe and considers some possible trends in the choice of support schemes in the future.

    In urban area, due to their beneficial effect on environment, electric vehicles, hybrid electric vehicles and fuel cell electric vehicles are an important factor for improvement of traffic and more particular for a healthier environment. Moreover, the need for alternative energy source is growing and the price competition of alternatives against oil is becoming more and more realistic. Electric vehicles, hybrid electric vehicles and fuel cell electric vehicles are offering the best possibility for the use of new energy sources, because electricity can result from a transformation with high efficiency of these sources and is always used with the highest possible efficiency in systems with electric drives or components. Some basic considerations about the situation today and in a mid and long-term perspective, are presented together with the infrastructure developments.

    As the Germans have decided to abandon nuclear energy, which today provides 23 % of their electricity, while fossil fuels provide 58%, the authors aim at answering two important questions. The first one is whether it is possible to cope without the non carbon nuclear energy while simultaneously reducing the CO{sub 2} emissions. Considering the current level of German CO{sub 2} emissions (over 9 tonnes per year per person), while the objective is to reach less than 2 tonnes per year by 2050, the second question is whether energy efficiency and renewable energies can be the solution. The authors present several scenarios meeting the overall emission objectives (a scenario dividing by two CO{sub 2} emissions between 2008 and 2050, and eight scenarios aiming at five times less emissions in 2050 than in 2008), with different transition periods for nuclear energy. Since in all the scenarios, there is no nuclear left in 2050, they examine the energy balance in 2050 and point out the main characteristics of the German energy mix at that time. Almost identical with another document with the same title, this version contains figures which are not present in the other one

    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

    Electricity consumption in German households accounts for more than 10 % of energy-related CO{sub 2} emissions. In spite of substantial improvements in, for example, the efficiency of household appliances, there is still a considerable electricity savings potential to be tapped in this sector. The possible contribution that the German residential sector can make to climate protection is correspondingly large. This paper aims to structure and quantify electricity savings potentials which could be exploited in German households either through investment measures or changed user behaviour. The total theoretical potential which can be tapped through the purchase of efficient household appliances and the replacement of electrical heaters and hot water generators (i.e. by encouraging investment) amounts to approx. 90 TWh/a. This corresponds to more than 60 % of the current electricity demand of all German households. By means of changed user behaviour, approx. 30 TWh of electricity could be saved according to our calculations. These results presented in this article were reached within the scope of the TRANSPOSE interdisciplinary research project. This project is funded within the framework of the 'Social-ecological Research' programme of the German Federal Ministry for Education and Research.

  12. Renewable Electricity Futures: Exploration of a U.S. Grid with 80% Renewable Electricity

    2013-04-01

    Renewable Electricity Futures is an initial investigation of the extent to which renewable energy supply can meet the electricity demands of the contiguous United States over the next several decades. This study explores the implications and challenges of very high renewable electricity generation levels: from 30% up to 90% (focusing on 80%) of all U.S. electricity generation from renewable technologies in 2050. At such high levels of renewable electricity penetration, the unique characteristics of some renewable resources, specifically geographical distribution and variability and un-certainty in output, pose challenges to the operability of the nation's electric system. The study focuses on key technical implications of this environment from a national perspective, exploring whether the U.S. power system can supply electricity to meet customer demand on an hourly basis with high levels of renewable electricity, including variable wind and solar generation. The study also identifies some of the potential economic, environmental, and social implications of deploying and integrating high levels of renewable electricity in the U.S. The full report and associated supporting information is available at: http://www.nrel.gov/analysis/refutures/.

    Future accelerators will make extensive use of superconductors made of Nb{sub 3}Sn, which allows higher magnetic fields than NbTi. However, the wind-and-react technology of Nb{sub 3}Sn superconducting magnet production makes polyimide Kapton® non applicable for the coils' electrical insulation. A Nb{sub 3}Sn technology compatible insulation material should be characterized by high radiation resistivity, good thermal conductivity, and excellent mechanical properties. Candidate materials for the electrical insulation of future accelerator's magnet coils have to be radiation certified with respect to potential degradation of their electrical, thermal, and mechanical properties. This contribution presents procedures and results of tests of the electrical and mechanical properties of DGEBA epoxy + D400 hardener, which is one of the candidates for the electrical insulation of future magnets. Two test sample types have been used to determine the material degradation due to irradiation: a untreated one (unirradiated) and irradiated at 77 K with 11 kGy/min intense, 4MeV energy electrons beam to a total dose of 50 MGy.

    Future accelerators will make extensive use of superconductors made of Nb3Sn, which allows higher magnetic fields than NbTi. However, the wind-and-react technology of Nb3Sn superconducting magnet production makes polyimide Kapton® non applicable for the coils' electrical insulation. A Nb3Sn technology compatible insulation material should be characterized by high radiation resistivity, good thermal conductivity, and excellent mechanical properties. Candidate materials for the electrical insulation of future accelerator's magnet coils have to be radiation certified with respect to potential degradation of their electrical, thermal, and mechanical properties. This contribution presents procedures and results of tests of the electrical and mechanical properties of DGEBA epoxy + D400 hardener, which is one of the candidates for the electrical insulation of future magnets. Two test sample types have been used to determine the material degradation due to irradiation: a untreated one (unirradiated) and irradiated at 77 K with 11 kGy/min intense, 4MeV energy electrons beam to a total dose of 50 MGy.

    The aim of the project is to elucidate how individual heating units for single family houses are best designed in order to fit into the future energy system. The units are based on solar energy, electrical heating elements/heat pump, advanced heat storage tanks and advanced control systems. Heat is produced by solar collectors in sunny periods and by electrical heating elements/heat pump. The electrical heating elements/heat pump will be in operation in periods where the heat demand cannot be covered by solar energy. The aim is to use the auxiliary heating units when the electricity price is low, e.g. due to large electricity production by wind turbines. The unit is equipped with an advanced control system where the control of the auxiliary heating is based on forecasts of the electricity price, the heat demand and the solar energy production. Consequently, the control is based on weather forecasts. Three differently designed heating units are tested in a laboratory test facility. The systems are compared on the basis of: 1) energy consumption for the auxiliary heating; 2) energy cost for the auxiliary heating; 3) net utilized solar energy. Starting from a normal house a solar combi system (for hot water and house heating) can save 20-30% energy cost, alone, depending on sizing of collector area and storage volume. By replacing the heat storage with a smart tank based on electric heating elements and a smart control based on weather/load forecast and electricity price information 24 hours ahead, another 30-40% can be saved. That is: A solar heating system with a solar collector area of about 10 m{sup 2}, a smart tank based on electric heating element and a smart control system, can reduce the energy costs of the house by at least 50%. No increase of heat storage volume is needed to utilize the smart control. The savings in % are similar for different levels of building insulation. As expected a heat pump in the system can further reduce the auxiliary electricity

    Researchers for the electricity industry, national laboratories, and state and federal agencies have begun to argue that the country could face water shortages resulting from the addition of thermoelectric power plants, but have not attempted to depict more precisely where or how severe those shortages will be. Using county-level data on rates of population growth collected from the US Census Bureau, utility estimates of future planned capacity additions in the contiguous United States reported to the US Energy Information Administration, and scientific estimates of anticipated water shortages provided from the US Geologic Survey and National Oceanic and Atmospheric Administration, this paper highlights the most likely locations of severe shortages in 22 counties brought about by thermoelectric capacity additions. Within these areas are some 20 major metropolitan regions where millions of people live. After exploring the electricity-water nexus and explaining the study's methodology, the article then focuses on four of these metropolitan areas - Houston, Texas; Atlanta, Georgia; Las Vegas, Nevada; New York, New York - to deepen an understanding of the water and electricity challenges they may soon be facing. It concludes by identifying an assortment of technologies and policies that could respond to these electricity-water tradeoffs. (author)

    In recent years, the amount of renewable energy sources in Europe has increased substantially. During the work on this thesis, wind and solar energy is added to the simulating tool, PSST. Where wind and solar energy are added the generation mix and the electricity prices are influenced. This is especially seen in Germany which has a lot of wind and solar energy at the present time, and are planning to increase an expansion in the future. In Germany this leads to a decrease in the use of lign...

    Electrical power is an indispensable tool in the industrialization of a developing country. An efficient, reliable source of electricity is a key factor in the establishment of a wide range of industries, and the supply of energy must keep pace with the increasing demand which economic growth creates in order for that growth to be sustained. As one of the most successful of all developing countries, Korea has registered impressive economic growth over the last decade, and it could be said that the rapid growth of the Korean economy would not have been possible without corresponding growth in the supply of electric power. Power producers in Korea, and elsewhere in Asia, are to be commended for successfully meeting the challenge of providing the necessary power to spur what some call an economic miracle. The future continues to hold great potential for participants in the electrical power industry, but a number of important challenges must be met in order for that potential to be fully realized. Demand for electricity continues to grow at a staggering rate, while concerns over the environmental impact of power generating facilities must not be ignored. As it becomes increasingly difficult to finance the rapid, and increasingly larger-scale expansion of the power industry through internal sources, the government must find resources to meet the growing demand at least cost. This will lead to important opportunities for the private sector. It is important, therefore, for those interested in participating in the power production industry and taking advantage of the newly emerging opportunities that lie in the Korean market, and elsewhere in Asia, to discuss the relevant issues and become informed of the specific conditions of each market.

    The future of the electricity industry will be shaped by five forces, already unleashed, and industry leaders` reaction to them. The opportunities for heady executives in well-positioned companies will extend far beyond the borders of today`s confined industry. How the game is played will determine whether utilities are the conquerors or vanquished. The future history of the industry will be written by those who are beginning to fashion their strategic responses to these forces: the deregulation of energy distribution, technological change, intellectual capital, interindustry convergence, and cultural dissonance. For most utilities, strategies are now being contemplated - come coherently, others inchoately - according to the perceived competences and weaknesses of each company in the eyes of its management and board.

    The volume of electricity sold to consumers in the voluntary green electricity market is growing continuously. On 1 January 2013 the Certificates of Origin Registry of the German Federal Environmental Office went into service. This authority obliges electricity suppliers in Germany to use its services if they wish to prove to their final customers that they are supplying them with electricity from ''other renewable resources''. This gives rise to the question as to how certificates of origin can contribute to the further development and to meaningful differentiation in the green electricity market.

    This document displays information and questions concerning the future organization of the French electric sector. The directive on the domestic electricity market was adopted in 1996 by the Council of the Ministers of European Union and Parliament. The member states were due to transpose the directive within their national legislation up to 19 February 1999. The directive establishes principles but provides large reaches of maneuver to the member states which can choose the organizational means according to their own expectations. These task is considered as feasible by the authors. It must reinforce the public service by giving added strength to the security of supply and ensuring everybody's access to a well marketed and high quality electric supply. By introduction of certain well controlled elements of competition this evolution should also contribute to cost lowering, boost of the national competitiveness and support of employment. The document contains seven chapters which expose the following items: 1. The objectives of reorganization; 2. The directive and its reach; 3. Strengthening the public service; 4. Revamping the electric service to promote the growth; 5. Preserving the grids for the general benefit; 6. Defining the place of EDF within the new organizational scheme; 7. Developing an efficient regulation. Finally, an appendix is given containing the Directive 96/92/CE of the European Parliament and Council of 19 October 1996, concerning the common rules for domestic electricity market.

  6. Future electricity production methods. Part 1: Nuclear energy

    The global warming challenge aims at stabilizing the concentrations of Green House Gas (GHG) in the atmosphere. Carbon dioxide is the most effective of the anthropogenic GHG and is essentially produced by consumption of fossil fuels. Electricity production is the dominant cause of CO2 emissions. It is, therefore, crucial that the share of 'carbon less' electricity production techniques increases at a fast pace. This is the more so, that 'clean' electricity would be useful to displace 'dirty' techniques in other fields such as heat production and transportation. Here we examine the extent to which nuclear energy could be operational in providing 'clean' electricity. A nuclear intensive scenario is shown to give the possibility to divide CO2 emissions by a factor of 2 worldwide, within 50 years. However, the corresponding sharp increase in nuclear power will put a heavy burden on uranium reserves and will necessitate the development of breeding reactors as soon as possible. A review of present and future reactors is given with special attention to the safety issues. The delicate question of nuclear fuel cycle is discussed concerning uranium reserves and management of used fuels. It is shown that dealing with nuclear wastes is more a socio-political problem than a technical one. The third difficult question associated with the development of nuclear energy is the proliferation risk. It is advocated that, while this is, indeed, a very important question, it is only weakly related to nuclear power development. Finally, the possibilities of nuclear fusion are discussed and it is asserted that, under no circumstances, could nuclear fusion give a significant contribution to the solution of the energy problem before 50 years, too late for dealing with the global warming challenge.

    Customer-sited photovoltaic (PV) systems in the United States are often compensated at the customer’s underlying retail electricity rate through net metering. Calculations of the customer economics of PV, meanwhile, often assume that retail rate structures and PV compensation mechanisms will not change and that retail electricity prices will increase (or remain constant) over time, thereby also increasing (or keeping constant) the value of bill savings from PV. Given the multitude of potential changes to retail rates and PV compensation mechanisms in the future, however, understanding how such changes might impact the value of bill savings from PV is critical for policymakers, regulators, utilities, the solar industry, and potential PV owners, i.e., any stakeholder interested in understanding uncertainties in and potential changes to the long-term customer economics of PV. This scoping study investigates the impact of, and interactions among, three key sources of uncertainty in the future value of bill savings from customer-sited PV, focusing in particular on residential customers. These three sources of uncertainty are: changes to electricity market conditions that would affect retail electricity prices, changes to the types of retail rate structures available to residential customers with PV, and shifts away from standard net-metering toward other compensation mechanisms for residential PV.

    The energy concept of the German federal government and the 2012 network development plan of the German Federal Network Agency both describe the future of the German energy supply system and in particular that of the electricity supply. A closer look reveals significant differences in the future projections of these scenarios. A comparison using the IKARUS energy supply system model shows that the differences are not negligible when it comes to assessing the German energy supply system as a whole. This concerns in particular future power plant capacities, CO{sub 2} emissions and the conversion costs incurred each year.

    This scoping study investigates the impact of, and interactions among, three key sources of uncertainty in the future value of bill savings from customer-sited PV, focusing in particular on residential customers. These three sources of uncertainty are: changes to electricity market conditions that would affect retail electricity prices, changes to the types of retail rate structures available to residential customers with PV, and shifts away from standard net-metering toward other compensation mechanisms for residential PV. We investigate the impact of a range of electricity market scenarios on retail electricity prices and rate structures, and the resulting effects on the value of bill savings from PV. The scenarios include various levels of renewable and solar energy deployment, high and low natural gas prices, the possible introduction of carbon pricing, and greater or lesser reliance on utility-scale storage and demand response. We examine the bill savings from PV with time-invariant, flat residential retail rates, as well as with time-varying retail rates, including time-of-use (TOU) rates and real-time pricing (RTP). In addition, we explore a flat rate with increasing-block pricing (IBP). We evaluate the bill savings from PV with net metering, as currently allowed in many states, as well as scenarios with hourly netting, a partial form of net metering. This scoping study is the first known effort to evaluate these types of interactions in a reasonably comprehensive fashion, though by no means have we considered every possible change to electricity market conditions, retail rate structures, or PV compensation mechanisms. It focuses solely on the private value of bill savings for residential PV and does not seek to quantify the broader social or economic cost or value of solar electricity. Our analysis applies assumptions based loosely on California’s electricity market in a future year (2030); however, it is neither intended to forecast California’s future

    Medical devices play a central role in the diagnosis and treatment of diseases but also bring the potential for adverse events, hazards or malfunction with serious consequences for patients and users. Medical device manufacturers are therefore required by law to monitor the performance of medical devices that have been approved by the competent authorities (post market surveillance). Conducting a nationwide online-survey in the German medical device sector in Q2/2014 in order to explore the current status of the use of post market instruments we obtained a total of 118 complete data sets, for a return rate of 36%. The survey included manufacturers of different sizes, producing medical devices of all risk classes. The post market instruments most frequently reported covered the fields of production monitoring and quality management as well as literature observation, regulatory vigilance systems, customer knowledge management and market observation while Post Market Clinical Follow-up and health services research were being used less for product monitoring. We found significant differences between the different risk classes of medical devices produced and the intensity of use of post market instruments. Differences between company size and the intensity of instruments used were hardly detected. Results may well contribute to the development of device monitoring which is a crucial element of the policy and regulatory system to identify device-related safety issues.

    This work addresses the effects of Geomagnetic Disturbances (GMDs) on the present bulk power system as well as the future smart grid, and discusses the mitigation of these geomagnetic impacts, so as to reduce the vulnerabilities of the electric power network to large space weather events. Solar storm characterized by electromagnetic radiation generates geo-electric fields that result in the flow of Geomagnetically Induced Currents (GICs) through the transmission lines, followed by transformers and the ground. As the ground conductivity and the power network topology significantly vary with the region, it becomes imperative to estimate of the magnitude of GICs for different places. In this paper, the magnitude of GIC has been calculated for New York State (NYS) with the help of extensive modelling of the whole NYS electricity transmission network using real data. Although GIC affects only high voltage levels, e.g. above 300 kV, the presence of coastline in NYS makes the low voltage transmission lines also susceptible to GIC. Besides this, the encroachment of technologies pertaining to smart grid implementation, such as Phasor Measurement Units (PMUs), Microgrids, Flexible AC Transmission System (FACTS), and Information and Communication Technology (ICT) have been analyzed for GMD impacts. Inaccurate PMU results due to scintillation of GPS signals that are affected by electromagnetic interference of solar storm, presence of renewable energy resources in coastal areas that are more vulnerable to GMD, the ability of FACTS devices to either block or pave new path for GICs and so on, shed some light on impacts of GMD on smart grid technologies.

  13. Performance requirements of automotive batteries for future car electrical systems

    Friedrich, R.; Richter, G.

    The further increase in the number of power-consuming functions which has been announced for future vehicle electrical systems, and in particular the effects of new starting systems on battery performance, requires a further optimization of the lead acid system coupled with effective energy management, and enhanced battery operating conditions. In the face of these increased requirements, there are proven benefits to splitting the functions of a single SLI battery between two separate, special-purpose batteries, each of which are optimized, for high power output and for high energy throughput, respectively. This will bring about a marked improvement in weight, reliability, and state of charge (SOC). The development of special design starter and service batteries is almost completed and will lead to new products with a high standard of reliability. The design of the power-optimized lead acid accumulator is particularly suitable for further development as the battery for a 42/36 V electrical system. This is intended to improve the efficiency of the generator and the various power-consuming functions and to improve start/stop operation thereby bringing about a marked reduction in the fuel consumption of passenger cars. This improvement can also be assisted by a charge management system used in conjunction with battery status monitoring.

    Wind and solar electricity is produced without direct CO2 emissions. However, the introduction of this electricity in the grid is delicate due to the intermittent character of its sources. Wind and solar production is characterized by multiple, strong variations in the electric power. These variations put stress on the grid where the total production of electricity must always be equal to the consumption. We present a synthesis of five studies conducted for Germany and France with different assumptions of electricity mixes, all with large shares of wind and solar power. These mixes are subjected to the dynamics of wind and solar production as recorded in 2010 (Germany), 2012 and 2013 (Germany and France). Common structural trends are exhibited when the results of simulations (instantaneous power distributions and average annual values) are expressed as a percentage of the annual reduced load to be produced by these intermittent energies. We focus on the evaluation of these trends and the resulting constraints on the grid. The results obtained make it possible to anticipate the problems brought about by a large share of renewable intermittent energies in the production of electricity. They show the need for backup production in order to complement the intermittent sources. This leads to CO2 emissions unless storage systems of large capacity are available.

    The German Insurance Association (GDV) analyzed the impacts of climate change for the German insurance market. The work was conducted in cooperation with Potsdam Institute for Climate Impact Research, Freie Universität Berlin and University of Cologne. Different approaches and data sets were used to analyze the impacts of winter storm, hail and floods. High-resolution loss records to residential buildings in Germany were provided. These daily records are available on a fine spatial level of administrative districts from 1997-2007. For the period of 1984-2008 daily losses to residential buildings were derived from motor vehicle own damage insurance, which shows a surprisingly high correlation between building losses and motor vehicle losses caused by natural hazards. Loss functions from GDVs own flood risk model were made available to estimate flood losses. As climate change will progress the mean annual losses in the private residential building insurance might increase. Until 2100 losses due to winter storm could rise by more than 50%. The increase is mainly attributable to the intensification of individual exceptionally severe storms. Climate change will also result in an increase of flood losses. By the end of the century mean losses are expected to be twice as high - depending on the given scenario they could remain constant or triple. Conversely extreme events with high cumulative losses are expected to become significantly more frequent. Storms with a today's return period of 50 years might occur every 10 years at the end of the century. Floods, now returning every 50 years, could arise every 25 years. For the first time hailstorms have been analyzed. It was noticed, that in particular East Germany might be hit more frequently. Despite these findings, i.e. the cost of insurance against natural hazards might increase, the extent of such an increase in Germany should still remain within limits that can be mastered by the insurance companies. But we have to

    2012-09-01

    Full Text Available The article contains scenarios for the power sector’s development until 2050, as proposed by students of Electrical High School No. 4 in Wloclawek. Many current trends in the development of technology have led the authors to attribute the verisimilitude to their selected visions of the future. The growing demand for energy, while fossil fuel resources and traditional methods of processing them are shrinking, will cause dissemination of the use of so-called environment-friendly sources of energy, such as wind or biomass. Energy will be commonly converted in domestic power stations equipped with energy storage capabilities and integrated with the grid by smart controllers for two-way energy transfer. The power grid role will change, and the existing energy consumers will become its prosumers. In the opinion of the authors the only alternative for this power sector development vision may be thermonuclear generation, which requires, however, incredibly high capital expenditures and level of technological development. However, launching thermonuclear power plants would free humanity from the fear of a future predominated by energy crisis.

    We present an overview of a complementary-approaches impact project dealing with the consequences of climate change for the natural hazard branch of the insurance industry in Germany. The project was conducted by four academic institutions together with the German Insurance Association (GDV) and finalized in autumn 2011. A causal chain is modeled that goes from global warming projections over regional meteorological impacts to regional economic losses for private buildings, hereby fully covering the area of Germany. This presentation will focus on wind storm related losses, although the method developed had also been applied in part to hail and flood impact losses. For the first time, the GDV supplied their collected set of insurance cases, dating back for decades, for such an impact study. These data were used to calibrate and validate event-based damage functions which in turn were driven by three different types of regional climate models to generate storm loss projections. The regional models were driven by a triplet of ECHAM5 experiments following the A1B scenario which were found representative in the recent ENSEMBLES intercomparison study. In our multi-modeling approach we used two types of regional climate models that conceptually differ at maximum: a dynamical model (CCLM) and a statistical model based on the idea of biased bootstrapping (STARS). As a third option we pursued a hybrid approach (statistical-dynamical downscaling). For the assessment of climate change impacts, the buildings' infrastructure and their economic value is kept at current values. For all three approaches, a significant increase of average storm losses and extreme event return levels in the German private building sector is found for future decades assuming an A1B-scenario. However, the three projections differ somewhat in terms of magnitude and regional differentiation. We have developed a formalism that allows us to express the combined effect of multi-source uncertainty on return

    Hospital information systems (HIS) should give support to nurses in their clinical and managerial duties. Though there are statistical data on the current use of HIS systems we know only little about the numbers of nursing modules implemented. We therefore conducted a nationwide survey in Germany (n = 2182) on the current state and future plans of HIS modules including nursing applications (response rate of 27.6 %). The findings show that management applications (84 % accounting) are still more frequent than clinical applications, in particular clinical patient record systems (19 %). What applied for HIS modules in general held also true for nursing on a lower level. Whereas 51 % of the hospitals had rostering systems in place only 6 % used care planning software.

    The paper describes the technical status and presents new concepts, models and approaches for the technical assistance of large scale wind power integration into the electrical energy supply system in Germany. It shows the technical and economic problems with the integration of high penetration of wind power plant in the network and the total electrical system. After an analysis of the effects of increased wind power generation on system planning and grid operation, we discuss innovative operational control concepts for large (offshore) wind farms. These concepts will provide a multitude of new possibilities to enable simple, flexible and undisturbed reaction to the demands of participants (wind farm operators, grid operators). These operational control strategies are mainly based on ISETs successful employed wind power prediction tools, operated by E.ON Netz (ENE), Vattenfall Europe Transmission (VE-T), RWE Transportnetz Strom (RWE) and will enable energy and power control, as well as the provision of reactive power, in order to achieve comparable properties to conventional power plant types.

    The topic ''CO{sub 2}-reduction within the electric power system'' should actually be preceded by a more general remark on the efficiency of energy policy from a macroeconomic perspective. An efficient and effective energy policy necessitates that the primary targets of such an energy policy, namely safeguarding a sustainable energy supply as well as considering environmental and climate objectives, are attained at the lowest possible costs. This corresponds to the general economic principle according to which given goals are to be achieved with relatively little effort and/or investments. That is beyond doubt because it means nothing else than to avoid any unnecessary waste of resources in order to reach such objectives.

    Recent US and European initiatives in Nuclear Propulsion lend themselves naturally to raising the question of comparing various options and particularly Nuclear Electric Propulsion (NEP) with Solar Electric Propulsion (SEP). SEP is in fact mentioned in one of the latest versions of the NASA Mars Manned Mission as a possible candidate. The purpose of this paper is to compare NEP, for instance, using high power MPD, Ion or Plasma thrusters, with SEP systems. The same payload is assumed in both cases. The task remains to find the final mass ratios and cost estimates and to determine the particular features of each technology. Each technology has its own virtues and vices: NEP implies orbiting a sizeable nuclear reactor and a power generation system capable of converting thermal into electric power, with minimum mass and volumes compatible with Ariane 5 or the Space Shuttle bay. Issues of safety and launch risks are especially important to public opinion, which is a factor to be reckoned with. Power conversion in space, including thermal cycle efficiency and radiators, is a technical issue in need of attention if power is large, i.e., of order 0.1 MW and above, and so is power conditioning and other ancillary systems. Type of mission, Isp and thrust will ultimately determine a large fraction of the mass to be orbited, as they drive propellant mass. For manned missions, the trade-off also involves consumables and travel time because of exposure to Solar wind and cosmic radiation. Future manned NEP missions will probably need superconducting coils, entailing cryostat technology. The on-board presence of cryogenic propellant (e.g., LH2) may reassure the feasibility of this technology, implying, however, a trade-off between propellant volume to be orbited and reduced thruster mass. SEP is attractive right now in the mind of the public, but also of scientists involved in Solar system exploration. Some of the appeal derives from the hope of reducing propellant mass because

    This study compares energy conversion systems for the generation of electrical power, with an emphasis on the Brazilian energy matrix. The financial model applied in this comparison is based on the Portfolio Theory, developed by Harry Markowitz. The risk-return ratio related to the electrical generation mix predicted in the National Energy Plan - 2030, published in 2006 by the Brazilian Energy Research Office, is evaluated. The increase of non-traditional renewable energy in this expected electrical generating mix, specifically, residues of sugar cane plantations and wind energy, reduce not only the risk but also the average cost of the kilowatt-hour generated.

  13. Using a policy mix to combat climate change. An economic evaluation of policies in the German electricity sector

    2010-01-28

    abatement under a policy mix of emissions trading and a tax, (2) it shows that the policy mix is in fact likely to reduce this inefficiency compared to a single suboptimal tax, and (3) it proposes modifications of emissions trading design which may bring down welfare losses under the policy mix even further. These new insights are necessary for the careful evaluation and design of a policy mix in the presence of multiple policy objectives and criteria. The third important contribution of this book is the evaluation of the climate policy mix in the German electricity sector - a case study that is very representative for the industrialized world. This evaluation can claim to be the most extensive analysis which is available for an existing policy mix. It applies the theoretical findings made in this book but also goes beyond them by considering further details of policy design and institutional environment. Particular attention is paid to the question which policies should complement emissions trading. It is shown that the additional implementation of energy efficiency labelling and low-interest loans promoting technological innovation and diffusion clearly raises efficiency. Support schemes for renewable energies and combined heat and power plants as well as energy-efficiency standards are likely to also produce welfare gains when combined with emissions trading. However, certain design features of these policies may impair the overall efficiency of the policy mix. Finally, it is argued that only electricity taxation and voluntary agreements cannot be justified as components of a policy mix. In summary, the German case study thus confirms that there may be many instances in which a policy mix is needed - but also that the details of policy design matter for the overall performance of the policy mix.

  14. The German way to an energy efficient future. Process and cross cutting technology improvements for CO{sub 2} reductions and a competitive economy

    Energy Technology Data Exchange (ETDEWEB)

    Radgen, P.

    1999-07-01

    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

    This report provides the analysis of environmental inventories for selected electricity supply systems considered as possible options to meet the expected electricity demand in Switzerland in year 2030. Two possible electricity demand level cases were postulated by VSE, both under the basic assumption of economic growth: a high-growth demand case corresponding to a yearly increase of 2% from year 1995 to year 2010 and 1% from year 2010 to year 2030, and a low-growth demand case corresponding to a yearly increase of 1% from year 1995 to year 2010 and 0.5% from year 2010 to year 2030. The base (i.e. secured) supply in year 2030 will be, according to VSE, totally dominated by hydro with rather minor contributions from combined heat-and-power plants, small gas turbines, incinerators and solar photovoltaic plants. Due to decommissioning of the currently operating nuclear power plants and expiration of long-term electricity import contracts there will eventually occur a gap between the postulated electricity demand and the base supply. VSE provided seven options to cover this gap, defined in terms of mixes with different contributions from gas, coal, nuclear and solar chains; in this context a distinction is also made with respect to shares of domestic and imported electricity. The systems considered represent advanced technologies, regarded as either typical or most suitable for the Swiss conditions. System-specific input to the present analysis has been partially generated based on direct contacts with the industry. Life Cycle Analysis (LCA) was used to establish environmental inventories for the systems analysed. The analysis has been performed on three levels:(1) individually for each system considered, (2) comparison of systems, (3) comparison of supply options. Results are also provided for these three levels.

    The electricity grid in the United States is organized around a network of large, centralized power plants and high voltage transmission lines that transport electricity, sometimes over large distances, before it is delivered to the customer through a local distribution grid. This network of centralized generation and high voltage transmission lines is called the “bulk power system.” Costs relating to bulk power generation typically account for more than half of a customer’s electric bill.1 For this reason, the structure and functioning of wholesale electricity markets have major impacts on costs and economic value for consumers, as well as energy security and national security. Diverse arrangements for bulk power wholesale markets have evolved over the last several decades. The Southeast and Western United States outside of California have a “bilateral-based” bulk power system where market participants enter into long-term bilateral agreements — using competitive procurements through power marketers, direct arrangements among utilities or with other generation owners, and auctions and exchanges.

    2008-07-01

    In the course of the next ten to fifteen years almost half of Germany's installed power plant capacity will need to be replaced by the construction of new facilities. The power plant investments required for this will be made in an environment marked by liberalisation and competition. This is the context of the present article, which analyses the causes behind the cyclical behaviour of power plant investment and identifies factors that influence it. Cycles in this connection are defined as recurring oscillations in power plant capacity and electricity prices. The authors also propose measures that could dampen the cyclical course of power plant investment over time. One of the major outcomes of the present model calculations is that the power production market, similarly to other capital-intensive branches of industry, is expected to experience strong price fluctuations in the future as well. As it has been framed up to now, the German electricity wholesale market will not be able to prevent the occurrence investment cycles in power plant construction. One way to counteract investment cycles would be to greatly expand the time horizon of the liquid spot market through greater activity on the part of trading firms.

    A heated discussion is being waged in Germany and large parts of Europe over the introduction of what are referred to as capacity mechanisms, whose purpose is to provide security of supply in the electricity sector. In this context two consulting firms have undertaken a both qualitative and quantitative study of the fitness of the present market design, which is based on the ''Energy-Only Market'' (EOM), to provide security of supply in the German electricity market. The authors come to the conclusion that, if suitably framed, the EOM can continue to provide a secure electricity supply in accordance with consumer preferences and at the lowest possible cost.

    Energy Technology Data Exchange (ETDEWEB)

    1999-07-01

    The economies of Estonia, Latvia and Lithuania developed in close association with the north-west region of the former Soviet Union. This is especially true for energy supply systems and electricity generation and transmission; the Baltic States depend on Russia for much of their primary energy needs, and export power to Russia and Belarus. In restructuring their electricity industries, the Baltic States hope to establish closer relationships and trade with Western Europe. The initial focus has been on changes to the legislative framework, industry restructuring and the establishment of new regulatory institutions. Vertically integrated utilities are in the process of being broken up into a number of separate generation, transmission and distribution companies. This restructuring is a prelude to privatisation. The states aim to establish a common power market among themselves, and hope to integrate this market with neighbouring (Nordic and European) markets. Despite the target set by the Baltic authorities of a common market by 2001, there is little clarity, as yet, on the framework and guidelines for the structure and functioning of the market. This process is supported by other players in the region, and the EU has recently prioritised closer co-operation and harmonisation of power networks in the Baltic Sea region. The Swedish National Energy Administration has identified cooperation on energy and environmental issues in the Baltic Sea region as one of its priorities. Consequently, the Administration commissioned ECON to analyse the conditions for closer linkages between the Baltic and Nordic electricity systems. This report presents the findings of this analysis.

  5. Critical review: Uncharted waters? The future of the electricity-water nexus.

    2015-01-06

    Electricity generation often requires large amounts of water, most notably for cooling thermoelectric power generators and moving hydroelectric turbines. This so-called "electricity-water nexus" has received increasing attention in recent years by governments, nongovernmental organizations, industry, and academics, especially in light of increasing water stress in many regions around the world. Although many analyses have attempted to project the future water requirements of electricity generation, projections vary considerably due to differences in temporal and spatial boundaries, modeling frameworks, and scenario definitions. This manuscript is intended to provide a critical review of recent publications that address the future water requirements of electricity production and define the factors that will moderate the water requirements of the electric grid moving forward to inform future research. The five variables identified include changes in (1) fuel consumption patterns, (2) cooling technology preferences, (3) environmental regulations, (4) ambient climate conditions, and (5) electric grid characteristics. These five factors are analyzed to provide guidance for future research related to the electricity-water nexus.

    2016-11-22

    Oriented external electric fields (OEEFs) as 'smart reagents' are no longer a theoretical dream. Here, we discuss the wide-ranging potential of using OEEFs to catalyse and control a variety of non-redox reactions and impart selectivity at will. An OEEF along the direction of electron reorganization (the so-called reaction axis) will catalyse nonpolar reactions by orders of magnitude, control regioselectivity and induce spin-state selectivity. Simply flipping the direction of the OEEF or orienting it off of the reaction axis, will control at will the endo/exo ratio in Diels-Alder reactions and steps in enzymatic cycles. This Perspective highlights these outcomes using theoretical results for hydrogen abstraction reactions, epoxidation of double bonds, C-C bond forming reactions, proton transfers and the cycle of the enzyme cytochrome P450, as well as recent experimental data. We postulate that, as experimental techniques mature, chemical syntheses may become an exercise in zapping oriented molecules with OEEFs.

    This study has been made to assess the needs, potential benefits and the applicability of early (circa year 2000) Nuclear Electric Propulsion (NEP) technology in conducting NASA science missions. The study goals are: to obtain the performance characteristics of near term NEP technologies; to measure the performance potential of NEP for important OSSA missions; to compare NEP performance with that of conventional chemical propulsion; to identify key NEP system requirements; to clarify and depict the degree of importance NEP might have in advancing NASA space science goals; and to disseminate the results in a format useful to both NEP users and technology developers. This is a mission performance study and precludes investigations of multitudes of new mission operation and systems design issues attendant in a NEP flight.

    We discuss in this paper the medium- and long- terms evolution of nuclear power in Brazil considering official governmental studies and reports prepared by research groups. The documents reviewed include the national energy balance (BEN, 2014), the short-term planning (PDEE, 2023) and long-term planning (PNE-2030) documents emitted by EPE, and studies conducted by independent institutions and researchers. The studies consider different scenarios regarding gross national product growth and institutional development for the country and conclude that nuclear power should increase its role in Brazil. The generation matrix should diversity by 2030 and 2040 with hydropower decreasing its share from today's 70 % to values between 47 and 57 %. Nuclear power is considered a viable alternative for base load electricity generation in Brazil; to reduce generation risks during dry seasons, and to facilitate the operation of the whole power generation system. The share of nuclear power may reach values between 8 % and 15 % by 2040 according to different scenarios. To meet such growth and facilitate new investments, it is necessary to change the legal framework of the sector, and allow private ownership of enterprises to build and operate nuclear power plants in the country.

    In this work, the study of germane flow rate in electrical properties of a-SiGe:H films is presented. The a-SiGe:H films deposited by low frequency plasma-enhanced chemical vapor deposition at 300 °C were characterized by Fourier transform infrared spectroscopy, measurements of temperature dependence of conductivity and UV–visible spectroscopic ellipsometry. After finding the optimum germane flow rate conditions, a-SiGe:H films were deposited at 200 °C and analyzed. The use of a-SiGe:H films at 200 °C as active layer of low-temperature ambipolar thin-film transistors (TFTs) was demonstrated. The inverted staggered a-SiGe:H TFTs with Spin-On Glass as gate insulator were fabricated. These results suggest that there is an optimal Ge content in the a-SiGe:H films that improves its electrical properties. - Highlights: • As the GeH{sub 4} flow rate increases the content of oxygen decreases. • Ge-H bonds show the highest value in a-SiGe:H films with GeH{sub 4} flow of 105 sccm. • Films with GeH{sub 4} flow of 105 sccm show the highest activation energy. • An optimum incorporation of germanium is obtained with GeH{sub 4} flow rate of 105 sccm. • At 200 °C the optimum condition of the a-SiGe:H films remain with no changes.

    The study investigates the development of the fossil fuel fired power generation in Europe up to 2030 and identifies the critical factors that influence its evolution. Through the application of the least-cost expansion planning methods, the technology and fuel mix of fossil fuel power plant portfolios emerging from the twenty-four techno-economic scenarios are described. The different scenarios present alternative views for the role of non-fossil fuel power generation, the development of the world fuel and carbon markets and the carbon capture power generating technologies. The study estimates the needs for new fossil fuel capacity and identifies the optimal power plant mix for all possible combinations of the cases mentioned above. The impacts of the resulting portfolios on the objectives of the European energy policy are assessed using as indicators the capital investment fo the construction of the required capacity, the fuel consumption, the composition of the fuel mix, the CO{sub 2} emission levels, and the average production cost of electricity from the fossil fuelled fleet. The report finds that high CO{sub 2} prices need to be maintained and carbon capture technology must be developed and become commercialised. If these conditions re met and medium or high fossil fuel prices prevail, the portfolio of fossil fuel power plants that will be deployed will be compatible wit the European goal for the development of a more sustainable and secure energy system. The key conclusion is that for a sustainable and secure energy system we need to invest, both in the increase of non-fossil fuel power generation and to ensure that carob n capture and storage technologies are ready to be deployed when needed. 46 refs.,

    China's oil imports and greenhouse gas (GHG) emissions have grown rapidly over the past decade. Addressing energy security and GHG emissions is a national priority. Replacing conventional vehicles with electric vehicles (EVs) offers a potential solution to both issues. While the reduction in petroleum use and hence the energy security benefits of switching to EVs are obvious, the GHG benefits are less obvious. We examine the current Chinese electric grid and its evolution and discuss the implications for EVs. China's electric grid will be dominated by coal for the next few decades. In 2015 in Beijing, Shanghai, and Guangzhou, EVs will need to use less than 14, 19, and 23 kWh/100 km, respectively, to match the 183 gCO2/km WTW emissions for energy saving vehicles. In 2020, in Beijing, Shanghai, and Guangzhou EVs will need to use less than 13, 18, and 20 kWh/100 km, respectively, to match the 137 gCO2/km WTW emissions for energy saving vehicles. EVs currently demonstrated in China use 24-32 kWh/100 km. Electrification will reduce petroleum imports; however, it will be very challenging for EVs to contribute to government targets for GHGs emissions reduction.

    Hydropower is a well established electricity system on the global scene. Global electricity needs by far exceed the amount of electricity that hydrosystems can provide to meet global electricity needs. Much of the world's hydropower remains to be brought into production. Improved technology, better calibrated environmental parameters for large projects have become the norm in the past 15 years. How and why does hydropower retain a prominent role in electricity production? How and why does hydropower find social acceptance in diverse social systems? How does hydropower project planning address issues beyond electricity generation? How does the systems approach to hydropower installations further analysis of comparative energy sources powering electricity systems? Attention to the environmental impact of hydropower facilities forms an integral part of systems analysis. Similarly, the technical, political and economic variables call for balanced analysis to identify the viability status of hydro projects. Economic competition among energy systems requires in context assessments as these shape decision making in planning of hydropower systems. Moreover, technological change has to be given a time frame during which the sector advances in productivity and share in expanding electricity generation. The low production costs per kWh assure hydropower at this juncture, 2009, a very viable future. (author)

    Full Text Available Brazil’s status as a rapidly developing country is visible in its need for more energy, including electricity. While the current electricity generation mix is primarily hydropower based, high-quality dam sites are diminishing and diversification to other sources is likely. We combined life-cycle data for electricity production with scenarios developed using the IAEA’s MESSAGE model to examine environmental impacts of future electricity generation under a baseline case and four side cases, using a Monte-Carlo approach to incorporate uncertainty in power plant performance and LCA impacts. Our results show that, under the cost-optimal base case scenario, Brazil’s GHGs from electricity (excluding hydroelectric reservoir emissions rise 370% by 2040 relative to 2010, with the carbon intensity per MWh rising 100%. This rise would make Brazil’s carbon emissions targets difficult to meet without demand-side programs. Our results show a future electricity mix dominated by environmental tradeoffs in the use of large-scale renewables, questioning the use tropical hydropower and highlighting the need for additional work to assess and include ecosystem and social impacts, where information is currently sparse.

    2013-09-01

    Recent studies on the relationship between thermoelectric cooling and water resources have been made at coarse geographic resolution and do not adequately evaluate the localized water impacts on specific rivers and water bodies. We present the application of an integrated electricity generation-water resources planning model of the Apalachicola/Chattahoochee/Flint (ACF) and Alabama-Coosa-Tallapoosa (ACT) rivers based on the regional energy deployment system (ReEDS) and the water evaluation and planning (WEAP) system. A future scenario that includes a growing population and warmer, drier regional climate shows that benefits from a low-carbon, electricity fuel-mix could help maintain river temperatures below once-through coal-plants. These impacts are shown to be localized, as the cumulative impacts of different electric fuel-mix scenarios are muted in this relatively water-rich region, even in a warmer and drier future climate.

    Carbon dioxide emissions from electricity generation are a major cause of anthropogenic climate change. The deployment of wind and solar power reduces these emissions, but is subject to the variability of the weather. In the present study, we calculate the cost-optimized configuration of variable electrical power generators using weather data with high spatial (13-km) and temporal (60-min) resolution over the contiguous US. Our results show that when using future anticipated costs for wind and solar, carbon dioxide emissions from the US electricity sector can be reduced by up to 80% relative to 1990 levels, without an increase in the levelized cost of electricity. The reductions are possible with current technologies and without electrical storage. Wind and solar power increase their share of electricity production as the system grows to encompass large-scale weather patterns. This reduction in carbon emissions is achieved by moving away from a regionally divided electricity sector to a national system enabled by high-voltage direct-current transmission.

    Thailand has a critical need for effective long-term energy planning because of the country's rapidly increasing energy consumption. In this study, the demand for electricity by the residential sector is modeled using a framework that provides detailed estimates of the timing and spatial distribution of changes in energy demand. A population model was developed based on the Cohort-Component method to provide estimates of population by age, sex and urban/non-urban residency in each province. A residential electricity end user model was developed to estimate future electricity usage in urban and non-urban households of the seventy-six provinces in Thailand during the period 1999--2019. Key variables in this model include population, the number of households, family household size, and characteristics of eleven types of electric household appliance such as usage intensity, input power, and saturation rate. The methodology employed in this study is a trending method which utilizes expert opinion to estimate future variables based on a percentage change from the most current value. This study shows that from 1994 to 2019 Thailand will experience an increase in population from 55.4 to 83.6 million. Large percentage population increases will take place in Bangkok, Nonthaburi, Samut Prakarn, Nakhon Pathom and Chonburi. At a national level, the residential electricity consumption will increase from approximately 19,000 to 8 1,000 GWh annually. Consumption in non-urban households will be larger than in urban households, with respective annual increases of 8.0% and 6.2% in 2019. The percent increase of the average annual electricity consumption will be four times the average annual percent population increase. Increased electricity demand is largely a function of increased population and increased demand for high-energy appliances such as air conditioners. In 1994, air conditioning was responsible for xx% of total residential electricity demand. This study estimates that in

We show how the calibration of the market price of risk to actively traded futures contracts allows for efficient valuation of Nord Pool's Asian-style options written on the spot electricity price. Furthermore, we study the evolution of the market price of risk (and the risk premium) over a three year time period and compare the obtained results with those reported in the literature. (author)

    An Alternative Scenario for the electric energy future of the Pacific Northwest is presented. The Scenario includes an analysis of each major end use of electricity in the residential, commercial, manufacturing, and agricultural sectors. This approach affords the most direct means of projecting the likely long-term growth in consumption and the opportunities for increasing the efficiency with which electricity is used in each instance. The total demand for electricity by these end uses then provides a basis for determining whether additional central station generation is required to 1995. A projection of total demand for electricity depends on the combination of many independent variables and assumptions. Thus, the approach is a resilient one; no single assumption or set of linked assumptions dominates the analysis. End-use analysis allows policymakers to visualize the benefits of alternative programs, and to make comparison with the findings of other studies. It differs from the traditional load forecasts for the Pacific Northwest, which until recently were based largely on straightforward extrapolations of historical trends in the growth of electrical demand. The Scenario addresses the supply potential of alternative energy sources. Data are compiled for 1975, 1985, and 1995 in each end-use sector.

    Today´s written part of the medical state examination requires students to retrieve a comprehensive amount of knowledge in a limited period of time. Therefore, the main study objectives were to implement and to evaluate a two-day exam preparation course for the German Medical State Examination in obstetrics and gynecology. The project evaluation focused on acceptability, satisfaction and the gain of knowledge for the participants of such a face-to-face course. The two-day intensive training for senior medical students offered a review of the entire exam-relevant content in the field of obstetrics and gynecology in combination with interactive discussions along selected exam questions. Skill gains were assessed using pre- and post-course multiple choice tests. In addition, a qualitative questionnaire assessed attitudes and satisfaction of course participants. A total of 101 fifth year senior medical students from Heidelberg University Medical School participated in the two pilot courses (summer 2014 and winter 2015). Pre- and post-course tests showed a significant skill-gain from 14.9 to 18.0 points [of a maximum of 20; pre-post difference 95 % CI (2.21; 3.98), t test: p obstetrics and gynecology is feasible, effective and highly appreciated by senior medical students preparing for the Second German Medical State Examination. It further suggests surplus value for academic clinical departments to recruit future residents. Methods and tools presented in this paper are intended to inspire and guide clinical colleagues in implementing the format at their respective universities.

    2017-08-01

    Electrical energy storage could play a pivotal role in future low-carbon electricity systems, balancing inflexible or intermittent supply with demand. Cost projections are important for understanding this role, but data are scarce and uncertain. Here, we construct experience curves to project future prices for 11 electrical energy storage technologies. We find that, regardless of technology, capital costs are on a trajectory towards US$340 ± 60 kWh‑1 for installed stationary systems and US$175 ± 25 kWh‑1 for battery packs once 1 TWh of capacity is installed for each technology. Bottom-up assessment of material and production costs indicates this price range is not infeasible. Cumulative investments of US$175-510 billion would be needed for any technology to reach 1 TWh deployment, which could be achieved by 2027-2040 based on market growth projections. Finally, we explore how the derived rates of future cost reduction influence when storage becomes economically competitive in transport and residential applications. Thus, our experience-curve data set removes a barrier for further study by industry, policymakers and academics.

    Full Text Available In the mid-nineteenth century Franz Kugler and Karl Schnaase decisively shaped the conception of art history as a discipline. Both explored connections between art of former epochs and that of the present. They understood the art of their day to be the result of a tradition of modernity based on the Renaissance and pointing into the future. Schnaase took an evolutionistic view similar to that of the architect Gottfried Semper: both advised against planning a programmatic new style. For Semper, the potential of new developments lay in the continuation of design patterns inherited from the earliest humans.

    Organized futures markets adapt the prices to changed market conditions within seconds. The advantages of futures markets over long-term contracts are evident considering that the announcement of futures prices restricts the freedom of valuation. Electricity futures market analyses have shown that the futures trade is a feasible alternative for the electric power industry. In addition, the futures trade ensures an optimum allocation of risks by distributing risks among the strongest and most resistant parties, which must not necessarily come from the electric power sector. The fact that the present futures market does not really fulfil all the functions which it could fulfil does not imply that it is bound to fail. The coming years will show the trends of this market, and will reveal the development of the index trade. (orig.)

    Today's electrical grids enjoy a relatively clean separation of spatio-temporal scales yielding a compartmentalization of grid design, optimization, control and risk assessment allowing for the use of conventional mathematical tools within each area. In contrast, the future grid will incorporate time-intermittent renewable generation, operate via faster electrical markets, and tap the latent control capability at finer grid modeling scales; creating a fundamentally new set of couplings across spatiotemporal scales and requiring revolutionary advances in mathematics techniques to bridge these scales. One example is found in decade-scale grid expansion planning in which today's algorithms assume accurate load forecasts and well-controlled generation. Incorporating intermittent renewable generation creates fluctuating network flows at the hourly time scale, inherently linking the ability of a transmission line to deliver electrical power to hourly operational decisions. New operations-based planning algorithms are required, creating new mathematical challenges. Spatio-temporal scales are also crossed when the future grid's minute-scale fluctuations in network flows (due to intermittent generation) create a disordered state upon which second-scale transient grid dynamics propagate effectively invalidating today's on-line dynamic stability analyses. Addressing this challenge requires new on-line algorithms that use large data streams from new grid sensing technologies to physically aggregate across many spatial scales to create responsive, data-driven dynamic models. Here, we sketch the mathematical foundations of these problems and potential solutions.

    Introduction We investigated the preferences of medical residents in Germany with regard to future working place (hospital or private practice) and position (employment/self-employment in private practice; resp. specialist/senior or chief physician in the hospital). This is analysed in a gender comparative perspective, including the influence of parenthood. Methods Annual postal surveys among graduates of seven medical faculties in Germany from their last year ("Practical Year") until after four years of postgraduate training. The return rate at baseline was 48 % and the four surveys after reached rates from 85 % up. In all samples about two thirds were women, which corresponds to the actual gender differentiation in under- and postgraduate training. Descriptive statistics and regression analyses were performed. Results Compared to private practice the hospital is clearly preferred, although the attraction of hospital jobs decreased over the years. The decision for or against the hospital is connected to the discipline. Working in private practice is seen as possibility for part time work. Men prefer self-employment whereas women prefer to work under an employment contract. In the hospital, male doctors prefer to work in leading positions. Those positions are associated with full-time work. Leadership training especially takes place in university hospitals. Discussion Three trends are recognized: Reluctance against leading positions, growing interest for part time work and rising popularity of work as an employee in private practice. Those trends can be understood as a rejection of traditional professional role models. The realization of these preferences is easily feasible because of the current labour market situation. Therefore, emerging problems have to be faced in another way. A change of gender-typical role models was rarely detected. © Georg Thieme Verlag KG Stuttgart · New York.

  19. Renewable Electricity Futures. Operational Analysis of the Western Interconnection at Very High Renewable Penetrations

    The Renewable Electricity Futures Study (RE Futures)--an analysis of the costs and grid impacts of integrating large amounts of renewable electricity generation into the U.S. power system--examined renewable energy resources, technical issues regarding the integration of these resources into the grid, and the costs associated with high renewable penetration scenarios. These scenarios included up to 90% of annual generation from renewable sources, although most of the analysis was focused on 80% penetration scenarios. Hourly production cost modeling was performed to understand the operational impacts of high penetrations. One of the conclusions of RE Futures was that further work was necessary to understand whether the operation of the system was possible at sub-hourly time scales and during transient events. This study aimed to address part of this by modeling the operation of the power system at sub-hourly time scales using newer methodologies and updated data sets for transmission and generation infrastructure. The goal of this work was to perform a detailed, sub-hourly analysis of very high penetration scenarios for a single interconnection (the Western Interconnection). It focused on operational impacts, and it helps verify that the operational results from the capacity expansion models are useful. The primary conclusion of this study is that sub-hourly operation of the grid is possible with renewable generation levels between 80% and 90%.

  20. Report for the Prime Minister. Making the future French electric power organization a success; Rapport au Premier Ministre. Reussir la future organisation electrique francaise

    Dumont, J.L

    1998-12-31

    This report from the French Deputy of the Meuse region aims at taking stock of four main questions raised by the future organization of the French electric power industry in the context of the opening of the European power market: the public utility of electric power, the future missions of Electricite de france (EdF) company, the questions in relation with the personnel status in the electric power industry, and the status of the regulating authority. In order to give some elements of answer to these questions, the report has been divided into 2 parts: part 1 presents the power production, transport and distribution in the future electric power regulation (the renewal of nuclear facilities, the building of non-nuclear units, the exploitation of the power distribution network, the accounting dissociation and the transparency of accountancy, the organization of network access, the eligible clients, the direct power lines, the obligations of purchase, the distribution and the role of local authorities). Part 2 presents the four main stakes of the modernization of the French electric power sector: the electric power public utility (public concern and rights, government policy, sustain of innovation, environment protection and energy mastery, the transportation and distribution networks, the role of operators and the financing), the future evolution of EdF (missions and organization, future of the public company), the social modernization of the electric power sector (present day status, adaptation, evolution, pensions), the organization and role of the future regulation authority. The propositions of the author are reported in the appendix. (J.S.)

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

    This report presents a description of the present Norwegian electric power system, as well as a discussion of emerging trends and future developments in this system. The report provides the basis for FFI's current vulnerability analysis of the electric power system. Norway's electric power system is getting increasingly complex, due to a large-scale implementation of electronic components and information systems. Workforce reductions and efficiency improvements dominate the development of the electric power sector. Norway is also becoming increasingly dependent on foreign power sources. These trends provide for an entirely different electric power system than just a few years ago. Also, these trends make it virtually impossible to present a ''static'' description of the system. Thus, the report also contains a scenario, describing possible future developments of the system until 2010. (author)

    Various types of reactor designs, electric power conversion equipment, and reject-heat systems to be used in nuclear reactor power plants for future space missions were studied. The designs included gas-cooled, liquid-cooled, and heat-pipe reactors. For the power converters, passive types such as thermoelectric and thermionic converters and dynamic types such as Brayton, potassium Rankine, and Stirling cycles were considered. For the radiators, heat pipes for transfer and radiating surface, pumped fluid for heat transfer with fins as the radiating surface, and pumped fluid for heat transfer with heat pipes as the radiating surface were considered. After careful consideration of weights, sizes, reliabilities, safety, and development cost and time, a heat-pipe reactor design, thermoelectric converters, and a heat-pipe radiator for an experimental program were selected.

  11. Distributed generation in European electricity markets. Current challenges and future opportunities

    Ropenus, S. (Technical Univ. of Denmark, Risoe National Lab. for Sustainable Energy. Systems Analysis Div., Roskilde (Denmark))

    This Ph.D. thesis studies the role of distributed generation in European electricity markets. It focuses primarily on the interactions of economics and policy with the aim of contributing to the understanding of how distributed generation is embedded in the present regulatory and market framework, which barriers exist, and which role it may possibly play in the future. To capture the interdisciplinarity of the topic, a combination of qualitative and quantitative methods is applied. Subsequent to the identification of barriers, this thesis turns to the microeconomic perspective on the interplay of vertical structure, regulation and distributed generation. This is done through the application of quantitative methods in the form of partial equilibrium models focusing on the effects induced by the vertical structure of the network operator, either a combined operator or a distribution system operator, in a market with small distributed producers. In areas where the promotion of renewable energy sources and combined heat and power has induced a substantial increase in distributed generation, new challenges in system integration arise. In particular, high levels of generation from intermittent energy sources, such as wind, add to the complexity of network operation and control, which can hardly be tackled with the present 'fit and forget' approach. The conclusion is that distributed generation has great potential to enhance competitiveness, sustainability and security of supply in European electricity markets. A prerequisite is the removal of market and regulatory barriers, taking the interdependencies of vertical structure, support mechanisms and network access into account. In the future, higher penetration levels of distributed generation necessitate changes in the power system and the adoption of new technologies, where hydrogen production by grid connected electrolysis constitutes one example.

    The electricity grid of the Netherlands is changing. There is a call of society to use more underground cables, less overhead lines (OHL) and to reduce magnetic emissions. At the same time, parts of the future transmission grid need strengthening depending on the electricity demand in the coming decades [1]. Novel high temperature superconductor (HTS) AC transmission cables can play a role in strengthening the grid. The advantages as compared to alternatives, are: economic, underground, higher power capacity, lower losses, reduced magnetic field emissions in (existing) OHL, compact: less occupation of land and less permits needed, a possibility to keep 380 kV voltage level in the grid for as long as needed. The main obstacles are: the relatively high price of HTS tapes and insufficient maturity of the HTS cable technology. In the paper we focus on a 34 km long connection in the transmission grid (to be strengthened in three of the four of TenneT scenarios [1]), present the network study results, derive the requirements for corresponding HTS transmission cable system and compare HTS system to the alternatives (OHLs and XLPE cables).

    NASA Glenn Research Center, in collaboration with the aerospace industry and academia, has begun the development of technology for a future hybrid-wing body electric airplane with a turboelectric distributed propulsion (TeDP) system. It is essential to design a subscale system to emulate the TeDP power grid, which would enable rapid analysis and demonstration of the proof-of-concept of the TeDP electrical system. This paper describes how small electrical machines with their controllers can emulate all the components in a TeDP power train. The whole system model in Matlab/Simulink was first developed and tested in simulation, and the simulation results showed that system dynamic characteristics could be implemented by using the closed-loop control of the electric motor drive systems. Then we designed a subscale experimental system to emulate the entire power system from the turbine engine to the propulsive fans. Firstly, we built a system to emulate a gas turbine engine driving a generator, consisting of two permanent magnet (PM) motors with brushless motor drives, coupled by a shaft. We programmed the first motor and its drive to mimic the speed-torque characteristic of the gas turbine engine, while the second motor and drive act as a generator and produce a torque load on the first motor. Secondly, we built another system of two PM motors and drives to emulate a motor driving a propulsive fan. We programmed the first motor and drive to emulate a wound-rotor synchronous motor. The propulsive fan was emulated by implementing fan maps and flight conditions into the fourth motor and drive, which produce a torque load on the driving motor. The stator of each PM motor is designed to travel axially to change the coupling between rotor and stator. This feature allows the PM motor to more closely emulate a wound-rotor synchronous machine. These techniques can convert the plain motor system into a unique TeDP power grid emulator that enables real-time simulation performance

    In this report, results and data from examinations concerning software-based electrical components and transmitters are evaluated. As failure modes of software-based com-ponents and failure causes differ fundamentally from non-software-based components, an evaluation of the operating experience of such components was carried out. This evaluation should show whether or not existing approaches for non-software-based components can be directly transferred to software-based components, or if a different approach has to be developed. To include failures in non-safety systems, events not fulfilling the incident reporting criteria of German authorities were also included in this evaluation. The data provided by licensees of six German NPPs (different Boiling Wa-ter Reactors and Pressurized Water Reactors) was recorded for at least 8 years. The software-based components used in the NPPs are identified and their operating experience is analyzed in order to identify relevant failure modes and to establish a II knowledge base for future failure rating. In addition, the state of the art and science concerning the specific components was described.

    This report provides a high-level indicator of the future electricity demand for additional electric power generation that is not met by existing generation sources between 2015 and 2050. The indicator is applied to coastal regions, including the Great Lakes, to assess the regional opportunity space for offshore wind. An assessment of opportunity space can be a first step in determining the prospects and the system value of a technology. The metric provides the maximal amount of additional generation that is likely required to satisfy load in future years.

    Because of its frequency, diverticular disease is a burden on health care systems. Only few formal guidelines covering all aspects of the disease exist. Here, some selected statements from the German guidelines are given. The guidelines include significant recommendations for the diagnosis and management of diverticular disease. Both diagnosis and management depend definitely on clear definitions of the situation of an individual patient. Therefore, a new classification is proposed that is based on earlier suggestions. An internationally established classification would not only enable better patient care but could also lead to studies with comparable results.

  19. An electricity-focused economic input-output model: Life-cycle assessment and policy implications of future electricity generation scenarios

    Science.gov (United States)

    Marriott, Joe

    The electricity industry is extremely important to both our economy and our environment. We would like to be able to examine the economic, environmental and policy implications of both future electricity scenarios which include advanced generation technologies such as gasified coal, and of the products and processes which will use them, along with the interaction of this industry with the rest of the economy. This work builds upon an existing economic input-output framework, by adding detail about the electricity industry, specifically by differentiating among the various functions of the sector, and the different means of generating power. The mix of electricity consumed at any stage in the life-cycle of a product, process or industrial sector has a significant effect on the associated inventory of emissions. Fossil fuel or nuclear generators, large-scale hydroelectric, and renewable options such as geothermal, wind and solar each have a unique set of issues---both in the production of electricity at the plant and throughout the supply chain. Decision makers need better information regarding the environmental and economic impact of the electricity industry, including full supply chain details---the interaction of the electricity industry with the other 500 sectors of the economy. A systematic method for creating updated state level and sector generation mixes is developed. The results show that most sector mixes are very close to the U.S. average due to geographic dispersion of industries, but that some sectors are different, and they tend to be important raw material extraction or primary manufacturing industries. We then build a flexible framework for creating new sectors, supply chains and emission factors for the generation, transmission and distribution portions of the electricity industry. We look at scenarios of the present and future, for electricity and for particular products, and develop results which show environmental impacts split up by generation

    This report addressed to the prime minister deals with the main four issues relating to the problem of revamping the French electricity sector. These are featured as: 1. The public electricity supply; 2. The future development of 'Electricite de France'; 3. The social renovation of the electricity sector; 4. Management and the role of policy. In turn these four chapters are detailed. Thus the first one addresses the problems: 1. Customizing the general interest supply; 2. Electricity general supply and the state policy; 3. Sustaining innovation, environmental protection and energy management; 4. The transport and distribution grid, the resistance structure of the public supply. Also, this chapter describes the role of the operators in the public electricity supply and tackles the problem of financing the commitments of the public supply. The second chapter sketches the tasks and management of EDF, considers establishing an agency to ensure accounting transparency, discusses the major significance of local collectivities and personnel. The third chapter addresses the following issues: 1. The range of application of the statute of electric and gas industries; 2. Adaptation of the statute; 3. Development of the statute; 4. Pensioners. The forth chapter deals with the definition of regulation, i.e. the management of the network authority and makes proposals for constituting relating commissions. In conclusion, the author pleads for maintaining and developing a major national operator ensuring public supply requirements as well as promotion of French electricity industry. The proposals made by the report's author concerning the operational ways of renewing the nuclear sector, the management of grid of electric transport, the role of local collectivities, creation of a professional trade, the founding regulation commissions and others are thought to prepare France to cope efficiently to the international competition in the years to come.

    Water is essential to electricity generation. Power plant cooling water is responsible for 40-50% of total freshwater withdrawals in Europe (Rübbelke et al., 2011) and the United States (Kenny et al., 2009). In accordance with growing demands for electricity generation, water demands could be increased. There is concern that the water demands for electricity generation could compete with other major water users. Additionally, many countries are required reviewing energy policies to mitigate climate change. Thermal power replaced low carbon power like renewable energy, nuclear power, Carbon Capture and Storage as a mitigation technology. However, influences of such climate change mitigation technologies on water demands are still uncertain. In this study, we calculated freshwater demands for electricity generation by using the data set of future electricity generation in the twenty-first century which estimated by the Asia-Pacific Integrated Model, and assessed the overall effects of electricity generation on water demands under the Shared Socio-Economic Pathways and the Representative Concentration Pathways which were adopted by IPCC AR5. Water demands for electricity generation depends on cooling types, such as once-through cooling and recirculating cooling. We also took into account cooling system pathways. The result might be useful for deciding energy policies which aim for reduction of water demands, especially in regions experiencing water scarcity.

    A major change is underway in the European Union electricity sector, where the electricity market will be partly opened for competition. There is a required minimum opening of the generation market, although countries may exceed it. However, given the very different structures, technological mixes and national cultures, will a single market be possible? This paper outlines three different scenarios of how the European electricity market might evolve. (au)

    German and Colombian strategic objectives, strengths and needs suit for a long-lasting cooperation ot mutual advantage in the fields of renewable energy resources (RES), energy efficiency biodiversity, biofuels: Colombia as a country rich of fossil primary energy carriers strives to substitute them by its abundant RES for the supply of electricity, heat (cold) and fuels, set them free for exporting to gain financial revenues for a self-determined technological development. Despite of its for a developing country relatively high technological level an indigenous industry of renewable energy hardly does not exist. Favourable interfaces in many regard prevail too in the energy related science, among others in biotechnology and the brand-new branch of urban agriculture. German middle-class enterprises and scientific institutes dispose of exactly suitable necessary technologies, engineering kow-how of their application and are increasingly obliged to look for foreign markets just in this segment. Joint research, development and implementation, including adapting high technologies to Colombian conditions is welcome to develop advanced knowledge and new applications. By growing cooperation of Latin American countries the chances for joint venturing with Colombian partners in the this market increase. FEE Foerdergesellschaft Erneuerbare Energien e.V. (Society for the Promotion of Renewable Energy) as a national network for innovations of enterprises, research institutes and experts has established a strong plexus to market relevant partners in Colombia since 2005, ready for manifold use by German partners in the branches of RES, energy efficiency and biofuels. FEE had been integrated into two Centres of Excellence recognized by the Colombian Research Council COLCIENCIAS. Powerful enterprises and associations signed official Letters of Interest.

    2009-03-15

    This paper reports theoretical economic production work and uses electricity futures trading to illustrate its argument. The focus is relationships between time, production and tradition both in Nicholas Georgescu-Roegen's analytical representation of the production process (i.e., flow/fund model) and in his dialectical scheme dealing with the evolutionary changes in the economic process. Our main arguments are (1) the flow/fund model is designed to be employed in conjunction with attention to how the boundaries of a given process are determined and (2) process boundaries are dialectical distinctions - between process and not-process - that are strongly related to time and tradition. We propose that Georgescu-Roegen's The Entropy Law and the Economic Process is best understood as the elaboration of a general theory of economic production and we developed two conceptual tools (time {open_square} and meta-funds), both of which are related to the dialectical distinction between process and not-process, which we use to operationalise this general theory. Finally, we demonstrate that, although trading in electricity futures is surprising if one uses a stock/flow vs services distinction (because electricity supply is classed as a service) it appears perfectly logical under Georgescu-Roegen's general theory: shortening time horizons, combined with a shift in the relationship between raw fuel supplies and power production procedures, lead to a shift in the status of electricity supply, from fund to flow.

  16. Super-sensing technology: industrial applications and future challenges of electrical tomography.

    Science.gov (United States)

    Wei, Kent Hsin-Yu; Qiu, Chang-Hua; Primrose, Ken

    2016-06-28

    Electrical tomography is a relatively new imaging technique that can image the distribution of the passive electrical properties of an object. Since electrical tomography technology was proposed in the 1980s, the technique has evolved rapidly because of its low cost, easy scale-up and non-invasive features. The technique itself can be sensitive to all passive electrical properties, such as conductivity, permittivity and permeability. Hence, it has a huge potential to be applied in many applications. Owing to its ill-posed nature and low image resolution, electrical tomography attracts more attention in industrial fields than biomedical fields. In the past decades, there have been many research developments and industrial implementations of electrical tomography; nevertheless, the awareness of this technology in industrial sectors is still one of the biggest limitations for technology implementation. In this paper, the authors have summarized several representative applications that use electrical tomography. Some of the current tomography research activities will also be discussed. This article is part of the themed issue 'Supersensing through industrial process tomography'.

    2012-07-01

    Compared to the previous year the German coal market recorded a slight fall in total consumption by 0.7% to 57.5 mill. coal units. Whereas coking coal and coke consumption of the steel industry clearly increased (+4.3%) due to the boom, sale of power station coals declined considerably in 2011 (-2.5%). However, electricity generation in Germany fell by almost the same amount (-2.2%). Primary energy consumption even declined by a good 5% to its lowest level since 1990 - probably because of the mild weather - and this despite economic growth of 3% in 2011. It must be stated that there was no increase in generation of electricity from bituminous coal following shutdown of eight of the 17 German nuclear power stations in the wake of the events at Fukushima although this was not the case with renewable energy and lignite. The political decisions in 2011 to expedite the energy turning point in Germany also do not suggest a continuous upward trend in the future. Bituminous coal occupied third place in the national energy mix in 2011 both in primary energy consumption and generation of electricity. Within the German coal market imported coal again compensated for the reduced contribution of indigenous coal. The indigenous coal mining industry has continued its politically prescribed decline according to plan. With the Council decision concerning coal subsidies in the EU, which came into force on 1 January 2011, and the deletion of the review clause in the Coal Financing Act approved by the German legislators cessation of the coal production in Germany at the end of 2018 has now become final and irreversible. At the same time the closure plan for the German coal mining industry extending to 2018 was approved by the EU Commission in December 2011. Meanwhile the RAG group is preparing its future after the end of the active mining industry inter alia by the use of available mining infrastructure for forms of renewable energy. (orig.)

    The emergence of distributed energy resources (DERs) that can generate, manage and store energy on the customer side of the electric meter is widely recognized as a transformative force in the power sector. This report focuses on two key aspects of that transformation: structural changes in the electric industry and related changes in business organization and regulation that are likely to result from them. Both industry structure and regulation are inextricably linked. History shows that the regulation of the power sector has responded primarily to innovation in technologies and business models that created significant structural changes in the sector’s cost and organizational structure.

  8. Water Resource Impacts Embedded in the Western US Electrical Energy Trade; Current Patterns and Adaptation to Future Drought

    2013-12-01

    Water resources are a key element in the global coupled natural-human (CNH) system, because they are tightly coupled with the world's social, environmental, and economic subsystems, and because water resources are under increasing pressure worldwide. A fundamental adaptive tool used especially by cities to overcome local water resource scarcity is the outsourcing of water resource impacts through substitutionary economic trade. This is generally understood as the indirect component of a water footprint, and as ';virtual water' trade. This work employs generalized CNH methods to reveal the trade in water resource impacts embedded in electrical energy within the Western US power grid, and utilizes a general equilibrium economic trade model combined with drought and demand growth constraints to estimate the future status of this trade. Trade in embedded water resource impacts currently increases total water used for electricity production in the Western US and shifts water use to more water-limited States. Extreme drought and large increases in electrical energy demand increase the need for embedded water resource impact trade, while motivating a shift to more water-efficient generation technologies and more water-abundant generating locations. Cities are the largest users of electrical energy, and in the 21st Century will outsource a larger fraction of their water resource impacts through trade. This trade exposes cities to risks associated with disruption of long-distance transmission and distant hydrological droughts.

    We estimate the consumptive water footprint (WF) of electricity and heat in 2035 for the four energy scenarios of the International Energy Agency (IEA) and a fifth scenario with a larger percentage of solar energy. Counter-intuitively, the 'greenest' IEA scenario (with the smallest carbon footprint) shows the largest WF increase over time: an increase by a factor four over the period 2010-2035. In 2010, electricity from solar, wind, and geothermal contributed 1.8% to the total. The increase of this contribution to 19.6% in IEA's '450 scenario' contributes significantly to the decrease of the WF of the global electricity and heat sector, but is offset by the simultaneous increase of the use of firewood and hydropower. Only substantial growth in the fractions of energy sources with small WFs - solar, wind, and geothermal energy - can contribute to a lowering of the WF of the electricity and heat sector in the coming decades. The fifth energy scenario - adapted from the IEA 450 scenario but based on a quick transition to solar, wind and geothermal energy and a minimum in bio-energy - is the only scenario that shows a strong decline in both carbon footprint (-66%) and consumptive WF (-12%) in 2035 compared to the reference year 2010.

    The EPA-MARKAL model of the U.S. electricity sector is used to examine how imposing emissions fees based on estimated health and environmental damages might change electricity generation. Fees are imposed on life-cycle emissions of SO(2), nitrogen oxides (NO(x)), particulate matter, and greenhouse gases (GHG) from 2015 through 2055. Changes in electricity production, fuel type, emissions controls, and emissions produced under various fees are examined. A shift in fuels used for electricity production results from $30/ton CO(2)-equivalent GHG fees or from criteria pollutant fees set at the higher-end of the range of published damage estimates, but not from criteria pollutant fees based on low or midrange damage estimates. With midrange criteria pollutant fees assessed, SO(2) and NOx emissions are lower than the business as usual case (by 52% and 10%, respectively), with larger differences in the western U.S. than in the eastern U.S. GHG emissions are not significantly impacted by midrange criteria pollutant fees alone; conversely, with only GHG fees, NO(x) emissions are reduced by up to 11%, yet SO(2) emissions are slightly higher than in the business as usual case. Therefore, fees on both GHG and criteria pollutants may be needed to achieve significant reductions in both sets of pollutants.

    Much of modern society is powered by inexpensive and reliable electricity delivered by a complex and elaborate electric power network. Electrical utilities are currently using the Global Positioning System-NAVSTAR (GPS) timekeeping to improve the network`s reliability. Currently, GPS synchronizes the clocks on dynamic recorders and aids in post-mortem analysis of network disturbances. Two major projects have demonstrated the use of GPS-synchronized power system measurements. In 1992, the Electric Power Research Institute`s (EPRI) sponsored Phase Measurements Project used a commercially available Phasor Measurements Unit (PMU) to collect GPS-synchronized measurements for analyzing power system problems. In 1995, Bonneville Power Administration (BPA) and Western Area Power Administration (WAPA) under DOE`s and EPRI`s sponsorship launched the Wide Area Measurements (WAMS) project. WAMS demonstrated GPS-synchronized measurements over a large area of their power networks and demonstrated the networking of GPS-based measurement systems in BPA and WAPA. The phasor measurement technology has also been used to conduct dynamic power system tests. During these tests, a large dynamic resistor was inserted to simulate a small power system disturbance.

    1992-08-25

    Much has been written about ceramic superconductors since their discovery in 1986. Most of this writing reports and describes scientific research. However, some authors have sought to put this research in context: to assess where the field stands, what might be technically feasible, what might be economically feasible, and what potential impacts ceramic superconductors will bring to the electric power sector. This report's purpose is to make the results of already published assessments readily available. To that end, this report lists and provides abstracts for various technical and economic assessments related to applications of High-Temperature Superconductors (HTS) to the electric power sector. Those studies deemed most important are identified and summarized. These assessments were identified by two means. First, members of the Executive Committee identified some reports as worthy of consideration and forwarded them to Argonne National Laboratory. Twelve assessments were selected. Each of these is listed and summarized in the following section. Second, a bibliographic search was performed on five databases: INSPEC, NTIS, COMPENDEX, Energy Science Technology, and Electric Power Database. The search consisted of first selecting all papers related to High Temperature Superconductors. Then papers related to SMES, cables, generators, motors, fault current limiters, or electric utilities were selected. When suitable variants of the above terms were included, this resulted in a selection of 493 citations. These citations were subjected to review by the authors. A number of citations were determined to be inappropriate (e.g. a number referred to digital transmission lines for electronics and communications applications). The reduced list consisted of 200 entries. Each of these citations, with an abstract, is presented in the following sections.

However, some authors have sought to put this research in context: to assess where the field stands, what might be technically feasible, what might be economically feasible, and what potential impacts ceramic superconductors will bring to the electric power sector. This report`s purpose is to make the results of already published assessments readily available. To that end, this report lists and provides abstracts for various technical and economic assessments related to applications of High-Temperature Superconductors (HTS) to the electric power sector. Those studies deemed most important are identified and summarized. These assessments were identified by two means. First, members of the Executive Committee identified some reports as worthy of consideration and forwarded them to Argonne National Laboratory. Twelve assessments were selected. Each of these is listed and summarized in the following section. Second, a bibliographic search was performed on five databases: INSPEC, NTIS, COMPENDEX, Energy Science & Technology, and Electric Power Database. The search consisted of first selecting all papers related to High Temperature Superconductors. Then papers related to SMES, cables, generators, motors, fault current limiters, or electric utilities were selected. When suitable variants of the above terms were included, this resulted in a selection of 493 citations. These citations were subjected to review by the authors. A number of citations were determined to be inappropriate (e.g. a number referred to digital transmission lines for electronics and communications applications). The reduced list consisted of 200 entries. Each of these citations, with an abstract, is presented in the following sections.

    This research assesses climate, technological, and policy impacts on consumptive water use from electricity generation in the Southwest over a planning horizon of nearly a century. We employed an integrated modeling framework taking into account feedbacks between climate change, air temperature and humidity, and consequent power plant water requirements. These direct impacts of climate change on water consumption by 2095 differ with technology improvements, cooling systems, and policy constraints, ranging from a 3-7% increase over scenarios that do not incorporate ambient air impacts. Upon additional factors being changed that alter electricity generation, water consumption increases by up to 8% over the reference scenario by 2095. With high penetration of wet recirculating cooling, consumptive water required for low-carbon electricity generation via fossil fuels will likely exacerbate regional water pressure as droughts become more common and population increases. Adaptation strategies to lower water use include the use of advanced cooling technologies and greater dependence on solar and wind. Water consumption may be reduced by 50% in 2095 from the reference, requiring an increase in dry cooling shares to 35-40%. Alternatively, the same reduction could be achieved through photovoltaic and wind power generation constituting 60% of the grid, consistent with an increase of over 250% in technology learning rates.

    Hybrid, plug-in hybrid, and battery electric vehicles--known collectively as electric drive vehicles (EDVs)--may represent a clean and affordable option to meet growing U.S. light duty vehicle (LDV) demand. The goal of this study is 2-fold: identify the conditions under which EDVs achieve high LDV market penetration in the U.S. and quantify the associated change in CO2, SO2, and NOX emissions through midcentury. We employ the Integrated MARKAL-EFOM System (TIMES), a bottom-up energy system model, along with a U.S. data set developed for this analysis. To characterize EDV deployment through 2050, varying assumptions related to crude oil and natural gas prices, a CO2 policy, a federal renewable portfolio standard, and vehicle battery cost were combined to form 108 different scenarios. Across these scenarios, oil prices and battery cost have the biggest effect on EDV deployment. The model results do not demonstrate a clear and consistent trend toward lower system-wide emissions as EDV deployment increases. In addition to the trade-off between lower tailpipe and higher electric sector emissions associated with plug-in vehicles, the scenarios produce system-wide emissions effects that often mask the effect of EDV deployment.

    The United States Department of Energy's SunShot Initiative has set cost-reduction targets of $1/watt for central-station solar technologies. We use SWITCH, a high-resolution electricity system planning model, to study the implications of achieving these targets for technology deployment and electricity costs in western North America, focusing on scenarios limiting carbon emissions to 80% below 1990 levels by 2050. We find that achieving the SunShot target for solar photovoltaics would allow this technology to provide more than a third of electric power in the region, displacing natural gas in the medium term and reducing the need for nuclear and carbon capture and sequestration (CCS) technologies, which face technological and cost uncertainties, by 2050. We demonstrate that a diverse portfolio of technological options can help integrate high levels of solar generation successfully and cost-effectively. The deployment of GW-scale storage plays a central role in facilitating solar deployment and the availability of flexible loads could increase the solar penetration level further. In the scenarios investigated, achieving the SunShot target can substantially mitigate the cost of implementing a carbon cap, decreasing power costs by up to 14% and saving up to $20 billion ($2010) annually by 2050 relative to scenarios with Reference solar costs.

    Full Text Available China had set an ambitious development target of electric vehicles (EVs to mitigate the environmental pollution. However, the actual situation of EVs far lagged behind the goals. This paper analyzes the elements impeding EVs’ development, which are identified into four contributors, including deficient EV subsidy policies, embarrassed EV market, local protectionism, and unmatched charging infrastructure. Based on the actual situation of China, this paper discusses corresponding policy suggestions and explores the alternative roadmap of EVs. In the initial development stage of EVs, it is important to select the appropriate charging mode for EVs according to different characteristics across users. Moreover, the development of hybrid electric vehicle (HEV may open the EV market faster than battery electric vehicle (BEV. In addition, the low-speed EVs may be a good choice for the rural market and should be well developed. With the promotion of EVs, China central and local governments should make rational policies to promote EVs’ development, which is the crucial force to drive the uptake of EVs.

  9. Electric vehicles — are they a realistic option for the future?

    Science.gov (United States)

    Dunckley, M.

    In the 1970s, as a result of rising oil prices and supply shortages, the concept of an 'electric vehicle programme' saw increased attention from legislative bodies, the automotive industry and general public groups. At that time, numerous 'experts' foresaw oil and fossil fuels running out early in the twenty-first century. As a result, a number of key issues came to the fore under the broad heading 'energy conservation'. A major part of this initiative was the need for a rethink of the automotive vehicle — the electric vehicle was considered a solution. In the event, the oil crisis of the 1970s came and went and the pressing debate for energy conservation and new vehicles went back into a more considered perspective. What emerged in the early 1980s was a new way of looking at automobiles. Cars were to become generally smaller and more fuel efficient. To add to the development of the car of the 1980s came a further new issue — the environment itself. The car became known as the single largest contributant to pollution. Increasing numbers of vehicles came to be seen as literally choking to death the planet earth. The next step in the story of the evolution of the vehicle was to control exhaust-gas emissions. One city, Los Angeles, even went so far as to legislate that by 1998, 2% of all new vehicles in the State must be 'zero gas' emitting. More North American states were to follow, to a point that every major car manufacturer in the world took note and has now embarked on a programme to develop a 'zero-gas' emitting vehicle. Today, the concept of an electric vehicle is back in focus. Throughout the world, the media are highlighting the electric vehicle as the next generation of transportation. The cynics argue that they have heard it all before, others believe that this time it could actually happen. For the battery industry, the implications could be enormous, and would change the industry as it is known worldwide. This paper discusses the options and

    The vision of an advanced information system is proposed to cope with the future social demand and business environmental change in electric utilities. At the large turning point such as drastic reconsideration of Electricity Utilities Industry Law, further improvement of efficiency and cost reduction are requested as well as business innovation such as proposal of a new business policy. For that purpose utilization of information and its technology is indispensable, and use of multimedia and common information in organization are the future direction for improving information basis. Consequently, free information networks without any limitation due to person and media are necessary, and the following are important: high-speed, high-frequency band, digital, easily connectable and multimedia transmission lines, and cost reduction and high reliability of networks. Based on innovation of information networks and the clear principle on advanced information system, development of new applications by multimedia technologies, diffusion of communication terminals, and promotion of standardization are essential. 60 refs., 30 figs., 5 tabs.

    The growth of economy and population together with the higher demand in energy has created many concerns for the Indian electricity industry whose capacity is at 211 gigawatts mostly in coal-fired plants. Due to insufficient fuel supply, India suffers from a shortage of electricity generation, leading to rolling blackouts; thus, performance evaluation and ranking the industry turn into significant issues. By this study, we expect to evaluate the rankings of these companies under control of the Ministry of Power. Also, this research would like to test if there are any significant differences between the two DEA models: Malmquist nonradial and Malmquist radial. Then, one advance model of MPI would be chosen to see these companies' performance in recent years and next few years by using forecasting results of Grey system theory. Totally, the realistic data 14 are considered to be in this evaluation after the strict selection from the whole industry. The results found that all companies have not shown many abrupt changes on their scores, and it is always not consistently good or consistently standing out, which demonstrated the high applicable usability of the integrated methods. This integrated numerical research gives a better "past-present-future" insights into performance evaluation in Indian electricity industry.

    Many regulators, utilities, customer groups, and other stakeholders are reevaluating existing regulatory models and the roles and financial implications for electric utilities in the context of today’s environment of increasing distributed energy resource (DER) penetrations, forecasts of significant T&D investment, and relatively flat or negative utility sales growth. When this is coupled with predictions about fewer grid-connected customers (i.e., customer defection), there is growing concern about the potential for serious negative impacts on the regulated utility business model. Among states engaged in these issues, the range of topics under consideration is broad. Most of these states are considering whether approaches that have been applied historically to mitigate the impacts of previous “disruptions” to the regulated utility business model (e.g., energy efficiency) as well as to align utility financial interests with increased adoption of such “disruptive technologies” (e.g., shareholder incentive mechanisms, lost revenue mechanisms) are appropriate and effective in the present context. A handful of states are presently considering more fundamental changes to regulatory models and the role of regulated utilities in the ownership, management, and operation of electric delivery systems (e.g., New York “Reforming the Energy Vision” proceeding).

  16. Historical Costs of Coal-Fired Electricity and Implications for the Future

    We study the costs of coal-fired electricity in the United States between 1882 and 2006 by decomposing it in terms of the price of coal, transportation costs, energy density, thermal efficiency, plant construction cost, interest rate, and capacity factor. The dominant determinants of costs at present are the price of coal and plant construction cost. The price of coal appears to fluctuate more or less randomly while the construction cost follows long-term trends, decreasing from 1902 - 1970, increasing from 1970 - 1990, and leveling off or decreasing a little since then. This leads us to forecast that even without carbon capture and storage, and even under an optimistic scenario in which construction costs resume their previously decreasing trending behavior, the cost of coal-based electricity will drop for a while but eventually be determined by the price of coal, which varies stochastically but shows no long term decreasing trends. Our analysis emphasizes the importance of using long time series and compari...

    AIM: To evaluate the current state-of-the-art of gastric electrical stimulation to treat obesity. METHODS: Systematic reviews of all studies have been conducted to evaluate the effect of different types of gastric electrical stimulation(GES) on obesity.RESULTS: Thirty-one studies consisting of a total of 33 different trials were included in the systematic review for data analysis. Weight loss was achieved in most studies, especially during the first 12 mo, but only very few studies had a follow-up period longer than 1 year. Among those that had a longer follow-up period, many were from the Transcend(Implantable Gastric Stimulation) device group and maintained significant weight loss. Other significant results included changes in appetite/satiety, gastric emptying rate, blood pressure and neurohormone levels or biochemical markers such as ghrelin or HbA1 c respectively. CONCLUSION: GES holds great promises to be an effective obesity treatment. However, stronger evidence is required through more studies with a standardized way of carrying out trials and reporting outcomes, to determine the long-term effect of GES on obesity.

    Full Text Available This paper describes the Experimental Power Grid Centre (EPGC microgrid test facility, which was developed to enable research, development and testing for a wide range of distributed generation and microgrid technologies. The EPGC microgrid facility comprises a integrated electrical and thermal grid with a flexible and configurable architecture, and includes various distributed energy resources and emulators, such as generators, renewable, energy storage technologies and programmable load banks. The integrated thermal grid provides an opportunity to harness waste heat produced by the generators for combined heat, power and cooling applications, and support research in optimization of combined electrical-thermal systems. Several case studies are presented to demonstrate the testing of different control and operation strategies for storage systems in grid-connected and islanded microgrids. One of the case studies also demonstrates an integrated thermal grid to convert waste heat to useful energy, which thus far resulted in a higher combined energy efficiency. Experiment results confirm that the facility enables testing and evaluation of grid technologies and practical problems that may not be apparent in a computer simulated environment.

    2015-12-01

    Full Text Available In the country like India with over millions of kilometers of transmission lines and billions of consumers, task of collecting information related to energy consumption of every consumer is a critical job. The meter reader has to travel a long distance and take reading manually to collect the data. This reading is then feed in a central database. Then the bill gets generated later with help of software. This project intends to reduce this tedious work by automating the process of collecting data from consumer’s electricity meter. This would be done by implementing Advanced Metering Infrastructure that unites all the various metering devices of a building in one network and provides the metering data in real-time, locally and from remote. Here, AMI uses ZigBee to build up high-rise building area network of connected metering devices.

    Full Text Available The experience of current outcomes influences future decisions in various ways. The neural mechanism of this phenomenon may help to clarify the determinants of decision-making. In this study, thirty-nine young adults finished a risky gambling task by choosing between a high- and a low-risk option in each trial during electroencephalographic data collection. We found that risk-taking strategies significantly modulated mean amplitudes of the event-related potential (ERP component P3, particularly at the central scalp. The event-related spectral perturbation and the inter-trial coherence measurements of the independent component analysis (ICA data indicated that the stay vs. switch electrophysiological difference associated with subsequent decision-making was mainly due to fronto-central theta and left/right mu independent components. Event-related cross-coherence results suggested that the neural information of action monitoring and updating emerged in the fronto-central cortex and propagated to sensorimotor area for further behavior adjustment. Based on these findings of ERP and event-related oscillation (ERO measures, we proposed a neural model of the influence of current outcomes on future decisions.

    Global Plants, a collaborative between JSTOR and some 300 herbaria, now contains about 2.48 million high-resolution images of plant specimens, a number that continues to grow, and collections that are digitizing their specimens at high resolution are allocating considerable recourses to the maintenance of computer hardware (e.g., servers) and to acquiring digital storage space. We here apply machine learning, specifically the training of a Support-Vector-Machine, to classify specimen images into categories, ideally at the species level, using the 26 most common tree species in Germany as a test case. We designed an analysis pipeline and classification system consisting of segmentation, normalization, feature extraction, and classification steps and evaluated the system in two test sets, one with 26 species, the other with 17, in each case using 10 images per species of plants collected between 1820 and 1995, which simulates the empirical situation that most named species are represented in herbaria and databases, such as JSTOR, by few specimens. We achieved 73.21% accuracy of species assignments in the larger test set, and 84.88% in the smaller test set. The results of this first application of a computer vision algorithm trained on images of herbarium specimens shows that despite the problem of overlapping leaves, leaf-architectural features can be used to categorize specimens to species with good accuracy. Computer vision is poised to play a significant role in future rapid identification at least for frequently collected genera or species in the European flora.

    2012-01-01

    Whole building input models for energy simulation programs are frequently created in order to evaluate specific energy savings potentials. They are also often utilized to maximize cost-effective retrofits for existing buildings as well as to estimate the impact of policy changes toward meeting energy savings goals. Traditional energy modeling suffers from several factors, including the large number of inputs required to characterize the building, the specificity required to accurately model building materials and components, simplifying assumptions made by underlying simulation algorithms, and the gap between the as-designed and as-built building. Prior works have attempted to mitigate these concerns by using sensor-based machine learning approaches to model energy consumption. However, a majority of these prior works focus only on commercial buildings. The works that focus on modeling residential buildings primarily predict monthly electrical consumption, while commercial models predict hourly consumption. This means there is not a clear indicator of which techniques best model residential consumption, since these methods are only evaluated using low-resolution data. We address this issue by testing seven different machine learning algorithms on a unique residential data set, which contains 140 different sensors measurements, collected every 15 minutes. In addition, we validate each learner's correctness on the ASHRAE Great Energy Prediction Shootout, using the original competition metrics. Our validation results confirm existing conclusions that Neural Network-based methods perform best on commercial buildings. However, the results from testing our residential data set show that Feed Forward Neural Networks, Support Vector Regression (SVR), and Linear Regression methods perform poorly, and that Hierarchical Mixture of Experts (HME) with Least Squares Support Vector Machines (LS-SVM) performs best - a technique not previously applied to this domain.

  11. Demands For Solar Electricity From The BRICS Countries In The Future

    Science.gov (United States)

    Fan, Y.

    2015-12-01

    BRICS countries are presently among the leading the economic powers globally, but their increasing demands for energy and sustainable future requires renewed technical progress on implementation of renewable energy (e.g., solar energy) and a sustainable solution rather than extracting finite natural resources. BRICS countries (Brazil, Russia, India, China and South Africa) face both social and environmental pressures as their economy keeps growing. The rapid development of technology in BRICS inevitably altered their culture and behavior, as reflected by education, gender equality, health, and other demographic/socio-economic indicators. These changes coupled with land use/land cover change have altered ecosystem services, as reflected by NEE (Net Ecosystem Exchange of CO2) and NDVI (Normalized Difference Vegetation Index). Global climatic changes also drives the demand for sustainable energy. With a focus on solar energy, we analyzed time series of energy consuming behaviors, government policies, and the ecosystem services. Structural equation modeling was applied to confirm the relationships among societal transition, ecosystem services, and climate change. We compared the energy consumption patterns for the five countries and forecasted the changes through 2025. We found that government policies significantly influenced energy consumption behaviors for BRICS and that solar energy usage would continue to increase to 2025 and beyond.

    Traditional management of electricity portfolios is focused on the day-ahead market and futures of longer maturity. Within limits, market participants can however also resort to the balancing energy market to close their positions. In this paper, we determine strategic positions in the balancing energy market and identify corresponding economic incentives in an analysis of the German balancing energy demand. We find that those strategies allow an economically optimal starting point for real-time balancing and create a marketplace for flexible capacity that is more open than alternative marketplaces. The strategies we proffer in this paper we believe will contribute to an effective functioning of the electricity market. (author)

  14. Lead-acid and lithium-ion batteries for the Chinese electric bike market and implications on future technology advancement

    Science.gov (United States)

    Weinert, Jonathan X.; Burke, Andrew F.; Wei, Xuezhe

    China has been experiencing a rapid increase in battery-powered personal transportation since the late 1990s due to the strong growth of the electric bike and scooter (i.e. e-bike) market. Annual sales in China reached 17 million bikes year -1 in 2006. E-bike growth has been in part due to improvements in rechargeable valve-regulated lead-acid (VRLA) battery technology, the primary battery type for e-bikes. Further improvements in technology and a transition from VRLA to lithium-ion (Li-ion) batteries will impact the future market growth of this transportation mode in China and abroad. Battery performance and cost for these two types are compared to assess the feasibility of a shift from VRLA to Li-ion battery e-bikes. The requirements for batteries used in e-bikes are assessed. A widespread shift from VRLA to Li-ion batteries seems improbable in the near future for the mass market given the cost premium relative to the performance advantages of Li-ion batteries. As both battery technologies gain more real-world use in e-bike applications, both will improve. Cell variability is a key problematic area to be addressed with VRLA technology. For Li-ion technology, safety and cost are the key problem areas which are being addressed through the use of new cathode materials.

  15. Bright future of photovoltaic-hybrid systems as main option for electricity generation in remote communities

    Zahedi, Ahmad [Solar Energy Applications Research Group (Australia)

    2000-07-01

    The most common power option for remotely located communities, facilities, schools, etc., is the engine generator powered by diesel fuel. Over the past 15 years, many remote communities with limited and costly site access for maintenance and fuel delivery have had their engine-based power systems modified to photovoltaic hybrid power systems. As a result, hybrid power systems with photovoltaic as the main generator are becoming the preferred power option. The reasons for this change are simple: the engine-based power systems require regular oil and filter changes (in average after 150 hrs of operation); the maintenance cost is relatively high; the cost of travel to and from the site to perform maintenance is restricted during certain time of the year and can be more expensive than the actual maintenance itself. Photovoltaic generators are gradually replacing the diesel generators and thus are becoming the primary source in remote communities. As electricity is required for 24 hours of operation and photovoltaic are not able to generate power for 24 h, batteries are added to the system as storage units, and the diesel generators are used as a back-up power supply. The objective of this paper is to present the results obtained from a study which has been carried out on a PV-hybrid power system from the desired performance point of view. [Spanish] La opcion mas comun de energia para las comunidades, instalaciones, escuelas, etc. localizadas en lugares remotos, es el generador que utiliza diesel como combustible.

Como resultado, los sistemas hibridos de energia con generadores fotovoltaicos como principal generador se estan convirtiendo en la opcion preferida de generacion de electricidad.

    Carbon capture and utilization (CCU) is a field of key emerging technologies. CCU can support the economy to decrease the dependency on fossil carbon raw materials, to stabilize electricity grids and markets with respect to a growing share of fluctuating renewable energy. Furthermore, it can contribute to mitigate anthropogenic CO2 emissions. The German Federal Ministry of Education and Research has provided substantial financial support for research and development projects, stimulating research, development, and innovations in the field of CO2 utilization. This review provides an overview over the most relevant funding measures in this field. Examples of successful projects demonstrate that CCU technologies are already economically viable or technologically ready for industrial application. CCU technologies as elements of a future "green economy" can contribute to reach the ambitious German sustainability targets with regard to climate protection as well as raw material productivity.

  17. History of German pediatric cardiology.

    Heintzen, P

    2002-01-01

    Due to the isolation of German medicine in World War II accompanied by the destruction of many hospitals, German pediatricians did not show any serious interest in the treatment of children with congenital heart diseases, nor did they take notice of the progress achieved by Helen Taussig, Alfred Blalock and other cardiologists and surgeons in the western world. This problem was even worse in East Germany. Only a few German internists and forward-looking surgeons were able and ready to take care of this group of principally operable children in places like Bonn/Düsseldorf, Marburg/Munich, Berlin, and Hamburg. However, in the early 1950s some directors of pediatrics at university hospitals--largely motivated by the cardiac surgeons--allowed or even encouraged younger colleagues to concentrate on pediatric cardiology and to begin application of heart catheterization and angiocardiography. In 1960 a group of colleagues interested in pediatric cardiology met for the first time in Frankfurt and became the nucleus of the future "working group" (1969) and finally the "German Society of Pediatric Cardiology" (1974). By 1972 pediatric cardiology had been approved as an independent (sub)specialty. Colleagues and friends from surrounding countries (Austria, Great Britain, Sweden, Switzerland, and the Netherlands) and also from the US and some eastern countries were either members or regular guests during or between the meetings. Pediatric cardiology is now represented in Germany by specialized practitioners, trainees and assistants who work in both community and university hospitals, and in specialized departments. Due to the foresightedness of the Chief of Pediatrics, Prof. G. Joppich, the first Chair of Pediatric Cardiology was founded in Göttingen in 1960 under the direction of A. Beuren. Another model of interdisciplinary cooperation between pediatric cardiologists, bioengineers, mathematicians and computer scientists was established in Kiel in 1966. In other places

  18. Impacts of compact growth and electric vehicles on future air quality and urban exposures may be mixed.

    'Smart' growth and electric vehicles are potential solutions to the negative impacts of worldwide urbanization on air pollution and health. However, the effects of planning strategies on distinct types of pollutants, and on human exposures, remain understudied. The goal of this work was to investigate the potential impacts of alternative urban designs for the area around Tampa, Florida USA, on emissions, ambient concentrations, and exposures to oxides of nitrogen (NOx), 1,3-butadiene, and benzene. We studied three potential future scenarios: sprawling growth, compact growth, and 100% vehicle fleet electrification with compact growth. We projected emissions in the seven-county region to 2050 based on One Bay regional visioning plan data. We estimated pollutant concentrations in the county that contains Tampa using the CALPUFF dispersion model. We applied residential population projections to forecast acute (highest hour) and chronic (annual average) exposure. The compact scenario was projected to result in lower regional emissions of all pollutants than sprawl, with differences of -18%, -3%, and -14% for NOx, butadiene, and benzene, respectively. Within Hillsborough County, the compact form also had lower emissions, concentrations, and exposures than sprawl for NOx (-16%/-5% for acute/chronic exposures, respectively), but higher exposures for butadiene (+41%/+30%) and benzene (+21%/+9%). The addition of complete vehicle fleet electrification to the compact scenario mitigated these in-county increases for the latter pollutants, lowering predicted exposures to butadiene (-25%/-39%) and benzene (-5%/-19%), but also resulted in higher exposures to NOx (+81%/+30%) due to increased demand on power plants. These results suggest that compact forms may have mixed impacts on exposures and health. 'Smart' urban designs should consider multiple pollutants and the diverse mix of pollutant sources. Cleaner power generation will also likely be needed to support aggressive adoption

  2. Can transcranial electrical stimulation improve learning difficulties in atypical brain development? A future possibility for cognitive training.

    Krause, Beatrix; Cohen Kadosh, Roi

    2013-10-01

    Learning difficulties in atypical brain development represent serious obstacles to an individual's future achievements and can have broad societal consequences. Cognitive training can improve learning impairments only to a certain degree. Recent evidence from normal and clinical adult populations suggests that transcranial electrical stimulation (TES), a portable, painless, inexpensive, and relatively safe neuroenhancement tool, applied in conjunction with cognitive training can enhance cognitive intervention outcomes. This includes, for instance, numerical processing, language skills and response inhibition deficits commonly associated with profound learning difficulties and attention-deficit hyperactivity disorder (ADHD). The current review introduces the functional principles, current applications and promising results, and potential pitfalls of TES. Unfortunately, research in child populations is limited at present. We suggest that TES has considerable promise as a tool for increasing neuroplasticity in atypically developing children and may be an effective adjunct to cognitive training in clinical settings if it proves safe. The efficacy and both short- and long-term effects of TES on the developing brain need to be critically assessed before it can be recommended for clinical settings.

  3. A Review of Additive Mixed-Electric Discharge Machining: Current Status and Future Perspectives for Surface Modification of Biomedical Implants

    Directory of Open Access Journals (Sweden)

    2017-01-01

    Full Text Available Surface treatment remained a key solution to numerous problems of synthetic hard tissues. The basic methods of implant surface modification include various physical and chemical deposition techniques. However, most of these techniques have several drawbacks such as excessive cost and surface cracks and require very high sintering temperature. Additive mixed-electric discharge machining (AM-EDM is an emerging technology which simultaneously acts as a machining and surface modification technique. Aside from the mere molds, dies, and tool fabrication, AM-EDM is materializing to finishing of automobiles and aerospace, nuclear, and biomedical components, through the concept of material migrations. The mechanism of material transfer by AM-EDM resembles electrophoretic deposition, whereby the additives in the AM-EDM dielectric fluids are melted and migrate to the machined surface, forming a mirror-like finishing characterized by extremely hard, nanostructured, and nanoporous layers. These layers promote the bone in-growth and strengthen the cell adhesion. Implant shaping and surface treatment through AM-EDM are becoming a key research focus in recent years. This paper reports and summarizes the current advancement of AM-EDM as a potential tool for orthopedic and dental implant fabrication. Towards the end of this paper, the current challenges and future research trends are highlighted.

  4. Advanced medium-voltage bidirectional dc-dc conversion systems for future electric energy delivery and management systems

    2011-12-01

    The distributed renewable energy generation and utilization are constantly growing, and are expected to be integrated with the conventional grid. The growing pressure for innovative solutions will demand power electronics to take an even larger role in future electric energy delivery and management systems, since power electronics are required for the conversion and control of electric energy by most dispersed generation systems Furthermore, power electronics systems can provide additional intelligent energy management, grid stability and power quality capabilities. Medium-voltage isolated dc-dc converter will become one of the key interfaces for grid components with moderate power ratings. To address the demand of medium voltage (MV) and high power capability for future electric energy delivery and management systems, the power electronics community and industry have been reacting in two different ways: developing semiconductor technology or directly connecting devices in series/parallel to reach higher nominal voltages and currents while maintaining conventional converter topologies; and by developing new converter topologies with traditional semiconductor technology, known as multilevel converters or modular converters. The modular approach uses the well-known, mature, and cheaper power semiconductor devices by adopting new converter topologies. The main advantages of the modular approach include: significant improvement in reliability by introducing desired level of redundancy; standardization of components leading to reduction in manufacturing cost and time; power systems can be easily reconfigured to support varying input-output specifications; and possibly higher efficiency and power density of the overall system. Input-series output-parallel (ISOP) modular configuration is a good choice to realize MV to low voltage (LV) conversion for utility application. However, challenges still remain. First of all, for the high-frequency MV utility application, the low

    1997-05-01

    Full Text Available This article analyses the issue of how the “post-socialist" civil society of the former GDR can be reconstructed to reduce dependence of the media on the state and on future private ownership, thereby maximising freedom of communication. The media had a powerful impact on the transitional phase following reunification. Before 1989 West German television and radio stations were "windows to the West". After reunification East Germans preferred to have their own newspapers, to watch their own television programmes or to listen to their own radio programmes. There has been some criticism about the quality of the media, but the majority of the contemporary audience is satisfied now. To meet the expectations of their audience the journalists themselves have learned to devote special attention to East German problems. One problem of concern is media concentration. Privatisation entails the danger that monopolising trends in mass media, especially in newspaper publishing, will continue in the new East German Lánder. Deregulation and quality programming offer an opportunity for a major breakthrough and new forms of media organisation and management. The period of acclimatisation following the reunification has, however, been too short for the mass media. Nevertheless, owing to specific characteristics of reunification, the transition East Germans have had to make has been largely successful.

    The German Neutron Scattering Conference 2012 - Deutsche Neutronenstreutagung DN 2012 offers a forum for the presentation and critical discussion of recent results obtained with neutron scattering and complementary techniques. The meeting is organized on behalf of the German Committee for Research with Neutrons - Komitee Forschung mit Neutronen KFN - by the Juelich Centre for Neutron Science JCNS of Forschungszentrum Juelich GmbH. In between the large European and international neutron scattering conferences ECNS (2011 in Prague) and ICNS (2013 in Edinburgh), it offers the vibrant German and international neutron community an opportunity to debate topical issues in a stimulating atmosphere. Originating from ''BMBF Verbundtreffen'' - meetings for projects funded by the German Federal Ministry of Education and Research - this conference series has a strong tradition of providing a forum for the discussion of collaborative research projects and future developments in the field of research with neutrons in general. Neutron scattering, by its very nature, is used as a powerful probe in many different disciplines and areas, from particle and condensed matter physics through to chemistry, biology, materials sciences, engineering sciences, right up to geology and cultural heritage; the German Neutron Scattering Conference thus provides a unique chance for exploring interdisciplinary research opportunities. It also serves as a showcase for recent method and instrument developments and to inform users of new advances at neutron facilities.

    Full Text Available Introduction. New neurorehabilitation together with conventional techniques provide methods and technologies for maximizing what is preserved from the sensory motor system after cerebrovascular insult. The rehabilitation technique named functional electrical therapy was investigated in more than 60 patients in acute, subacute and chronic phase after cerebrovascular insult. The functional sensory information generated by functional electrical therapy was hypothesized to result in the intensive functional brain training of the activities performed. Functional Electrical Therapy. Functional electrical therapy is a combination of functional exercise and electrical therapy. The functional electrical therapy protocol comprises voluntary movement of the paretic arm in synchrony with the electrically assisted hand functions in order to perform typical daily activities. The daily treatment of 30 minutes lasts three weeks. The outcome measures include several tests for the evaluation of arm/hand functionality: upper extremity function test, drawing test, modified Aschworth scale, motor activity log and passive range of movement. Results of Functional Electrical Therapy Studies. Results from our several clinical studies showed that functional electrical therapy, if applied in acute and subacute stroke patients, leads to faster and greater improvement of functioning of the hemiplegic arm/hand compared to the control group. The outcomes were significantly superior at all times after the treatment for the higher functioning group. Discussion. Additional well-planned clinical studies are needed to determine the adequate dose of treatment (timing, duration, intensity with functional electrical therapy regarding the patient’s status. A combination with other techniques should be further investigated.

    The German transmission system operators are obliged to make and publish forecasts on the development of the nationwide EEG apportionment on a calendar year basis. An important part of this study is a forecast of the electricity consumption to final consumers. In addition the electricity consumption of the self-suppliers,the final consumption is to be investigated according to the privilege categories for which the EEG apportionment has to be paid in a reduced amount. The final consumption amounted to about 463 TWh in 2014 and falls steadily to about 446 TWh by 2020. In 2016 the final consumption is about 460 TWh. The decline in final consumption is slightly more pronounced than in the case of net electricity demand, which is attributable to the rising self-supply. The net electricity demand in 2014 was about 513 TWh, which is about 15 TWh lower than in 2013. The decline is due in part to an increase in energy efficiency in electricity-based applications and on the other hand to mild weather. In the reference scenario, net electricity demand will decline from about 512 TWh in 2016 to about 506 TWh in 2020. The net electricity demand in the sectors of households and industry is decreasing, but increasing in the area of the TCS sector and the transport sector. In the course of the renewal of the EEG in 2014, regulations for the self-supply of electricity have been introduced for the first time, according to which operators of new plants larger than 10 kW and an annual self-sufficiency of more than 10 MWh have to pay a proportionate EEG apportionment, which increases in the subsequent years. While this regulation in the TCS sector leads to a stagnation of self-supply, the industrial sector is expected to continue replacement construction. An increase in the PV self-supply volume is expected for private households. Self-supply will increase from around 52 TWh in 2016 to around 53 TWh in 2020. The development of the future non-privileged final consumption, which is

    In January 1990 thirty-two experts from twelve countries convened for a five-day working Seminar on the Berkeley Campus of the University of California to discuss electricity supply and demand. The participants brought with them deep and diverse backgrounds in energy issues. A major concern of the First 1990 Group on Electricity was the potential impact of electricity shortages on the environment, just at a time of growing awareness of environmental deterioration. These concerns extend from local problems to nations, regions and global impacts. Indeed, because of the importance of electricity in our lives, potential electric power shortages already foreseeable in this decade could overwhelm public concern for the environment, unless critical, long-leadtime measures are taken very soon. The First 1990 Group on Electricity's Findings and Conclusions, the thinking that led to them, and the impact of events in the intervening year form the content of this book.

    "German is the language of science" I remember my father telling me as a boy growing up in the Bronx in New York during the 1970s. As I watched astronomy programmes on TV with my father and older brothers, I imagined having to speak ceaselessly in fluent German if I was ever to become a scientist as a grown-up. But when I started my studies at university in New York in the 1980s, I realized my father's advice - sought from weekly trips to the neighbourhood public library - was way out of date. Not only did my physics professors present their research in English at conferences all around the world, but they also published in English-language journals - thus seemingly not needing a single word of German.

    The research project examines whether a fleet of vehicles with electric propulsion system (xEV) can be integrated into existing and future energy supply systems for effective integration of fluctuating power production as well as for energy storage. A multi-sectoral, system-wide scenario analysis is performed to evaluate the grid integration of electric vehicles. The effect of an xEV fleet and the impacts of various battery charging scenarios, including the option of feeding power back into the grid, are addressed by detailed technical and economic models and summarized by an energy system model. The suitability of different powertrain concepts is analysed, giving consideration to their individual applications by users. Based on the results of a German nationwide survey of mobility patterns and analyses of 47 test subjects, individual driving profiles for private cars are drawn up and stored in a database. They are used as input for the vehicle energy model. This model calculates the energy requirements of different xEV concepts and facilitates optimized powertrain design and battery sizing for the respective applications. The results show that if the batteries are charged overnight it is possible to cover a major fraction of daily driving distances by electric power. Additional charging during the day does not significantly improve this fraction. The auxiliaries have a greater influence on the vehicle's energy demand than individual driving patterns. Battery lifetime is extended by recharging the battery as required and preferably as late as possible before the next trip. In most cases, using the batteries for grid services reduces battery lifetime and leads to higher specific costs. Models of the transmission grid and typical distribution grids are developed. It is shown that charging one million xEV in 2020 and six million in 2030 (as envisaged by the German Federal Government) is technically feasible without major structural modifications of the

    Full Text Available In August 1914 the majority of German Jews expressed their patriotic approval of the war and their loyalty to the German state. They identified with Germany, and a large number signed up voluntarily for military service at the front. The Jewish population in Germany affirmed the war not least because it was directed against Russia, the harshest adversary of the Jews. This paper concentrates on the first acts of war conducted by the German military forces during the German occupation of Belgium; it examines whether and in what way German-Jewish Intellectuals perceived Germany’s violation of Belgian neutrality and the new feature of war as a war against a civilian population. The first part examines autobiographical sources to reconstruct the experiences and the perception of German Jewish soldiers, German military rabbis, and other German Jewish witnesses to the war. The second part then analyzes the coverage of German Jewish newspapers regarding the warfare against Belgium; and, finally, the third and last part scrutinizes the commentaries of German Jewish intellectuals and socialist Jews [Jewish socialists?] regarding the German war against Belgium.

    The road transportation sector in Switzerland accounts for 44% of the whole greenhouse gas emissions of the country (around 52 million tons of CO{sub 2} equivalent, of which around 44 million tons of CO{sub 2}). The share of private cars is 72% of the road transportation emissions. The efficiency of electric vehicles is near 40% (useful energy/primary energy) in comparison to that of fossil fuel vehicles (15-20%). The European Union (EU) market average of CO{sub 2} emissions from passenger cars was about 160 g CO{sub 2}/km in 2005 and the average EU mix of electricity production had specific emissions of 410 g CO{sub 2}/kWh in the same year. In comparison the Swiss production mix was 34 CO{sub 2}/kWh in 2005, but the relevant Swiss consumption mix was 112 g CO{sub 2}/kWh, due to imports of electricity (with around 21% of the demand covered by imports). Hence a typical electric car will produce CO{sub 2} emissions of around 80 g CO{sub 2}/km in Europe, what is already twice better (in Switzerland: 23 g CO{sub 2}/km with the present consumption mix). By 2030 it is assumed that the EU electricity production mix will diminish to 130 g CO{sub 2}/kWh, and in Switzerland the consumption mix would be around 55 g CO{sub 2}/kWh (still calculated with 21% imports and with the same Swiss production mix), resulting in emissions from electric car in Europe of less than 30 g CO{sub 2}/km, and in Switzerland less than 13 g CO{sub 2}/km (all calculations made with a specific electric demand of 18-20 kWh/100 km). In summary, electrical vehicles retain a tremendous comparative advantage with respect to internal combustion engine vehicles. If 15% of the Swiss cars (i.e. 720,000 units) would be replaced by electrical vehicles, yearly CO{sub 2} emissions would decrease by about 1.2 million tons. This figure must be compared with the international commitment of Switzerland concerning its reduction of the global greenhouse gas emissions by 20%, i.e. 10.5 million tons of CO{sub 2

    The emergence of power exchanges is one of the key phenomena accompanying the liberation of the electricity industry. Apart from the Nordic countries, this is a recent event, especially for the countries of continental Europe. In this study, we will be focusing on the German electricity market for several reasons. Firstly, Germany has the largest market for electrical power in Europe. As the electricity sector is in the process of opening up to competition, this country is one of the 'good pupils' in the field of electrical deregulation. Next, it is a good idea to draw up an initial overview of the German experience following the launch on 27.11.2001 of an organised market in France (the PowerNext exchange). Currently, there are three exchanges able to negotiate contracts in the German hub: the Amsterdam Power Exchange (APX), the European Energy (EEX) and the Leipzig Power Exchange (LPX). The exchanges were created between May 1999 (APX) and August 2000 (EEX). They are in a situation of direct competition in the German market. This competition is particularly keen since the three players are well aware of the challenge at stake: becoming the leading exchange for the German market and (possibly) in a future integrated European market. The announcement of a merger between LPX and EEX in 2002 (published on 26.10.2001 on the sites of both exchanges) underlines the importance of these strategic issues. The purpose of this work is to carry out an assessment of the three exchanges during their first months in existence. Using an econometric analysis, we offer conclusions concerning the capacity of these exchanges to supply a reference price. The opportunities for arbitration are also examined. Despite the difficulties of the market launches, the exchanges have successfully maintained a certain degree of coherence in their prices and may now sit back a little and plan their expansion. It is difficult at this stage to see who the eventual 'winner' will

    Climate change has the potential to exacerbate reliability concerns for the power sector through changes in water availability and air temperatures. The power sector is responsible for 41% of U.S. freshwater withdrawals, primarily for power plant cooling needs, and any changes in the water available for the power sector, given increasing competition among water users, could affect decisions about new power plant builds and reliable operations for existing generators. Similarly, increases in air temperatures can reduce power plant efficiencies, which in turn increases fuel consumption as well as water withdrawal and consumption rates. This analysis describes an initial link between climate, water, and electricity systems using the National Renewable Energy Laboratory's (NREL) Regional Energy Deployment System (ReEDS) electricity system capacity expansion model. Average surface water runoff projections from Coupled Model Intercomparison Project 5 (CMIP5) data are applied to surface water available to generating capacity in ReEDS, and electric sector growth is compared with and without climate-influenced water availability for the 134 electricity balancing regions in the ReEDS model. In addition, air temperature changes are considered for their impacts on electricity load, transmission capacity, and power plant efficiencies and water use rates. Mean climate projections have only a small impact on national or regional capacity growth and water use because most regions have sufficient unappropriated or previously retired water access to offset climate impacts. Climate impacts are notable in southwestern states, which experience reduced water access purchases and a greater share of water acquired from wastewater and other higher-cost water resources. The electric sector climate impacts demonstrated herein establish a methodology to be later exercised with more extreme climate scenarios and a more rigorous representation of legal and physical water availability.

    The main objective of the German Environmental Specimen Bank (ESB) is the long-term storage of environmental and human samples under stable deep-freeze conditions for future research. The ESB is unique in providing a continuous historical record of environmental and human exposure to chemicals in Germany. ESB was started parallel to the development of the first German Chemicals Legislation in the late 1970s. In 1979, the ESB test operation began. After the Chemicals Law came into force in 1982, the ESB was established as a permanent facility in 1985. With the new European Chemicals Legislation, REACH, in 2007 responsibility for the safety of commercial chemicals and risk assessment was assigned to the industry. Since then, the ESB has become even more important in verifying the self-assessment of the industry, in evaluating the effectiveness of regulations, thus ensuring the protection of humans and the environment against adverse effects caused by exposure to chemicals. These objectives are pursued by the regular monitoring of contaminations and the assessment of temporal trends. Demonstrating the necessity of deriving exposure reduction measures, ESB results serve as key information for policy-makers. Information on preventing exposure to chemicals is available to the general public and to the public health services. The ESB is thus an important monitoring instrument of the Federal Ministry for the Environment, Nature Conservation, Building and Nuclear Safety. The Federal Environment Agency operates the ESB based on its own concepts, heads the scientific data evaluation and transfers results into the environmental policy arena and to the general public.

    2014-01-01

    Full Text Available Polymer nanocomposites have recently been attracting attention among researchers in electrical insulating applications from energy storage to power delivery. However, partial discharge has always been a predecessor to major faults and problems in this field. In addition, there is a lot more to explore, as neither the partial discharge characteristic in nanocomposites nor their electrical properties are clearly understood. By adding a small amount of weight percentage (wt% of nanofillers, the physical, mechanical, and electrical properties of polymers can be greatly enhanced. For instance, nanofillers in nanocomposites such as silica (SiO2, alumina (Al2O3 and titania (TiO2 play a big role in providing a good approach to increasing the dielectric breakdown strength and partial discharge resistance of nanocomposites. Such polymer nanocomposites will be reviewed thoroughly in this paper, with the different experimental and analytical techniques used in previous studies. This paper also provides an academic review about partial discharge in polymer nanocomposites used as electrical insulating material from previous research, covering aspects of preparation, characteristics of the nanocomposite based on experimental works, application in power systems, methods and techniques of experiment and analysis, and future trends.

    Affordable reliable energy made possible a large middle class in the industrial world. Concerns about climate change require a transition to nuclear, wind, and solar—but these energy sources in current forms do not have the capability to meet the requirements for variable affordable energy. Researchers from the Massachusetts Institute of Technology, the University of Tokyo, the Tokyo Institute of Technology and the Institute for Energy Economics are undertaking a series of studies to address how to make this transition to a low carbon world. Three areas are being investigated. The first area is the development of electricity grid models to understand the impacts of different choices of technologies and different limits on greenhouse gas emissions. The second area is the development of technologies to enable variable electricity to the grid while capital-intensive nuclear, wind and solar generating plants operate at full capacity to minimize costs. Technologies to enable meeting variable electricity demand while operating plants at high-capacity factors include use of heat and hydrogen storage. The third area is the development of electricity market rules to enable transition to a low-carbon grid.

    Economic impact of introduction in the future of photovoltaic power generation (PV) systems into the commercial power system is discussed from the electric utilities` point of view. In the discussion, future demand for power is predicted from the demand for power in the base year, and the optimum power source configuration corresponding to the future demand and power generation curve are worked out by use of linear programming. Then, the fixed cost and variable cost are calculated for each of the power source components, and then the expected reduction in cost per unit of power generated is calculated. As the power sources, the hydroelectric, pumped storage, oil-fired, coal-fired, LNG-fired, combined cycle, and atomic technologies are considered. The conclusion is stated below. Upon introduction of PV power equivalent to 10% of the maximum demand power, the maximum power in the service area of Chubu Electric Power Co., Inc., will be reduced by 1.23GW in 2025, and the yearly demand power by 5472GWh. Since PV lowers the peak, an increased number of power sources low in variable cost will be used although such will be low in tracking capability. An increase in power demand will enhance the cost reducing effect of the PV system. 5 refs., 4 figs., 3 tabs.

    Full Text Available It is known that the prejudices, which have emerged in the historical process, are engraved in the social memory of the nations; conveyed from the past to the future in language, art, literature, history and many other fields; and reproduced via media especially in the periods of crisis.Firstly, Turkish-German relations must be examined in the historical process in order to understand how Turkey and Turks are represented in the German media. Accordingly, Turkish-German relations are also important in terms of drawing a general framework on how the West, which has been preserving its topicality for centuries, sees Turkey.How the subjects and groups are represented in the media texts and what kind of an image are formed in relation with them reveals the social memory of the countries in which the media texts are produced.The prejudices which have emerged in the social memory of the German people in the historical process have an effect in forming the negative image of Turks by being reproduced via active media especially in the periods of crisis. A negative image of Turks is brought forward with the concepts such as human rights violations, fundamentalism, oppression against the women and the minorities, Kurdish-Turkish discrimination and Alawi-Sunni discrimination.German media uses as evidence and tries to emphasize their justness on the publications, photographs and images that take place in the Turkish media in terms of especially the concepts mentioned above.Media texts are dialogues which are formed between the target audience and the narrator who reflects the opinions of the authority elites that are the sources of news. For that reason, representation forms of Turkey and Turks will be associated with the historical prejudices and analyzed with the critical discourse analysis approach in the scope of this study.

  18. The past, present, and future of the U.S. electric power sector: Examining regulatory changes using multivariate time series approaches

    Science.gov (United States)

    Binder, Kyle Edwin

    The U.S. energy sector has undergone continuous change in the regulatory, technological, and market environments. These developments show no signs of slowing. Accordingly, it is imperative that energy market regulators and participants develop a strong comprehension of market dynamics and the potential implications of their actions. This dissertation contributes to a better understanding of the past, present, and future of U.S. energy market dynamics and interactions with policy. Advancements in multivariate time series analysis are employed in three related studies of the electric power sector. Overall, results suggest that regulatory changes have had and will continue to have important implications for the electric power sector. The sector, however, has exhibited adaptability to past regulatory changes and is projected to remain resilient in the future. Tests for constancy of the long run parameters in a vector error correction model are applied to determine whether relationships among coal inventories in the electric power sector, input prices, output prices, and opportunity costs have remained constant over the past 38 years. Two periods of instability are found, the first following railroad deregulation in the U.S. and the second corresponding to a number of major regulatory changes in the electric power and natural gas sectors. Relationships among Renewable Energy Credit prices, electricity prices, and natural gas prices are estimated using a vector error correction model. Results suggest that Renewable Energy Credit prices do not completely behave as previously theorized in the literature. Potential reasons for the divergence between theory and empirical evidence are the relative immaturity of current markets and continuous institutional intervention. Potential impacts of future CO2 emissions reductions under the Clean Power Plan on economic and energy sector activity are estimated. Conditional forecasts based on an outlined path for CO2 emissions are

    2015-01-01

    Full Text Available The growth of economy and population together with the higher demand in energy has created many concerns for the Indian electricity industry whose capacity is at 211 gigawatts mostly in coal-fired plants. Due to insufficient fuel supply, India suffers from a shortage of electricity generation, leading to rolling blackouts; thus, performance evaluation and ranking the industry turn into significant issues. By this study, we expect to evaluate the rankings of these companies under control of the Ministry of Power. Also, this research would like to test if there are any significant differences between the two DEA models: Malmquist nonradial and Malmquist radial. Then, one advance model of MPI would be chosen to see these companies’ performance in recent years and next few years by using forecasting results of Grey system theory. Totally, the realistic data 14 are considered to be in this evaluation after the strict selection from the whole industry. The results found that all companies have not shown many abrupt changes on their scores, and it is always not consistently good or consistently standing out, which demonstrated the high applicable usability of the integrated methods. This integrated numerical research gives a better “past-present-future” insights into performance evaluation in Indian electricity industry.

    The 2003 drought event in Europe had major implications on many societal sectors, including energy production, health, forestry and agriculture. The reduced availability of water accompanied by high temperatures led to substantial economic losses on the order of 1.5 Billion Euros, in agriculture alone. Furthermore, soil droughts have considerable impacts on ecosystems, forest fires and water management. Monitoring soil water availability in near real-time and at high-resolution, i.e., 4 × 4 km2, enables water managers to mitigate the impact of these extreme events. The German drought monitor was established in 2014 as an online platform. It uses an operational modeling system that consists of four steps: (1) a daily update of observed meteorological data by the German Weather Service, with consistency checks and interpolation; (2) an estimation of current soil moisture using the mesoscale hydrological model; (3) calculation of a quantile-based soil moisture index (SMI) based on a 60 year data record; and (4) classification of the SMI into five drought classes ranging from abnormally dry to exceptional drought. Finally, an easy to understand map is produced and published on a daily basis on www.ufz.de/droughtmonitor. Analysis of the ongoing 2015 drought event, which garnered broad media attention, shows that 75% of the German territory underwent drought conditions in July 2015. Regions such as Northern Bavaria and Eastern Saxony, however, have been particularly prone to drought conditions since autumn 2014. Comparisons with historical droughts show that the 2015 event is amongst the ten most severe drought events observed in Germany since 1954 in terms of its spatial extent, magnitude and duration.

    Full Text Available The article focuses on the toponymy of the Eastern part of modern Germany where Slavic and Germanic tribes were in contact during several centuries: in the 7th century the Slavs ousted Germanic tribes from this territory; then, since the early 10th century, the area started being repopulated by the Germans, which led to a Slavic-Germanic bilingualism (by the 13th century the domination of the Germanic population became evident. The author argues that these ethnic and linguistic contacts are reflected in the borrowing of geographic names and terms, as well as in Germanic-Slavic “hybrid” place names that the author proposes to call hybridonyms. The Slavs readily borrowed Old Germanic (“Pre-German” toponyms, the hybridonyms bearing traces of the late Proto-Slavic language. The author thoroughly analyzes a number of hybrid place names (Borgishain, Jenz, Leipzig, Jenzig reducing them to one toponymic type consisting of a Germanic stem and Slavic suffixes. A large part of the paper discusses the terms hybrid and hybridization as applied to place names and seeks to theoretically substantiate the term hybridonym.

    Full Text Available This study focuses on the development of electric vehicles (EV in the private passenger vehicle fleet in Beijing (China, analyzes how EVs will penetrate in the market, and estimates the resulting impacts on energy consumption and CO2 emissions up to 2030. A discrete choice model is adopted with consideration of variables including vehicle technical characteristics, fuel prices, charging conditions and support policies. Results show that by 2030, without technological breakthrough and support policies, the market share of EV will be less than 7%, with gasoline dominating the energy structure. With fast technological progress, charging facility establishment, subsidies and tax breaks, EVs will account for 70% of annual new vehicle sales and nearly half of the vehicle stock by 2030, resulting in the substitution of nearly 1 million tons of gasoline with 3.2 billion kWh electricity in 2030 and the reduction of 0.6 million tons of CO2 emission in 2030. Technological progress, charging conditions and fuel prices are the top three drivers. Subsidies play an important role in the early stage, while tax and supply-side policies can be good options as long-term incentives.

  9. Charging a renewable future: The impact of electric vehicle charging intelligence on energy storage requirements to meet renewable portfolio standards

    Increased usage of renewable energy resources is key for energy system evolution to address environmental concerns. Capturing variable renewable power requires the use of energy storage to shift generation and load demand. The integration of plug-in electric vehicles, however, impacts the load demand profile and therefore the capacity of energy storage required to meet renewable utilization targets. This study examines how the intelligence of plug-in electric vehicle (PEV) integration impacts the required capacity of energy storage systems to meet renewable utilization targets for a large-scale energy system, using California as an example for meeting a 50% and 80% renewable portfolio standard (RPS) in 2030 and 2050. For an 80% RPS in 2050, immediate charging of PEVs requires the installation of an aggregate energy storage system with a power capacity of 60% of the installed renewable capacity and an energy capacity of 2.3% of annual renewable generation. With smart charging of PEVs, required power capacity drops to 16% and required energy capacity drops to 0.6%, and with vehicle-to-grid (V2G) charging, non-vehicle energy storage systems are no longer required. Overall, this study highlights the importance of intelligent PEV charging for minimizing the scale of infrastructure required to meet renewable utilization targets.

    Science.gov (United States)

    Schmitt, Stéphane

    2009-01-01

    German biologist Ernst Haeckel (1834-1919) is often considered the most renowned Darwinian in his country since, as early as 1862, he declared that he accepted the conclusions Darwin had reached three years before in On the Origin of Species, and afterwards, he continuously proclaimed himself a supporter of the English naturalist and championed the evolutionary theory. Nevertheless, if we examine carefully his books, in particular his General Morphology (1866), we can see that he carries on a tradition very far from Darwin's thoughts. In spite of his acceptance of the idea of natural selection, that he establishes as an argument for materialism, he adopts, indeed, a conception of evolution that is, in some respects, rather close to Lamarck's views. He is, thus, a good example of the ambiguities of the reception of Darwinism in Germany in the second part of the 19th century.

    This document is an announcement of the Superior Council of Electricity and Gas (CSEG) concerning the future gas system of France. It was asked by the Secretary of State for industry having in view the preparation of the law of organization of gas sector. Without refraining to reveal the internal divergences, the CSEG intended to provide a framework of exchanges on the definition of Public Service in the field of natural gas, on regulation, on juridical regime of the gas transport and various relating subjects, as well as on the social questions. Also, the CSEG aimed at emphasizing a number of predominant points of view. It is stressed that the future law concerning the gas system should take into consideration the peculiarities of the activity in the gas sector, since the mere transposition into the gas sector of the measures valid in the electricity sector could is inadequate. The CSEG underlines its firm attachment to the notion of Public Service and the principle of subsidiarity. It also signals out the necessity of taking into account the industrial problems, i.e., placing the French gas operators into a more open position, turning synergically to good account the EDF, developing gas partnerships downstream and upstream and using vigorously its advantages. These issues should be also taken into account in case of industrial gas customers to ensure their competing European position. Price lowering as well as increasing the quality of services should be pursued actively. The document contains the following sections: I. The Public Service; II. The regulation; III. The juridical regime of transport, the distribution and the storage; IV. The social question.

    There are two principal pathways conceivable for the electric power industry to reduce CO[sub 2] emissions: 1. in supply (power generation, transmission and distribution); 2. in demand (rational use of energy). In power generation, this may be effected by improved efficiencies of conventional power stations; combined heat and power systems, energy carrier substitution, optimization models. In demand, this can be effected by savings (Negawatts) or efficiency enhancements in energy applications by means of multiple use of electric power (ecowatts). (BWI)

    Integrated assessment models project the future electricity generation mix under different policy, technology, and socioeconomic scenarios, but they do not directly address site-specific factors such as interconnection costs, population density, land use restrictions, air quality, NIMBY concerns, or water availability that might affect the feasibility of achieving the technology mix. Moreover, since these factors can change over time due to climate, policy, socioeconomics, and so on, it is important to examine the dynamic feasibility of integrated assessment scenarios "on the ground." This paper explores insights from coupling an integrated assessment model (GCAM-USA) with a geospatial power plant siting model (the Capacity Expansion Regional Feasibility model, CERF) within a larger multi-model framework that includes regional climate, hydrologic, and water management modeling. GCAM-USA is a dynamic-recursive market equilibrium model simulating the impact of carbon policies on global and national markets for energy commodities and other goods; one of its outputs is the electricity generation mix and expansion at the state-level. It also simulates water demands from all sectors that are downscaled as input to the water management modeling. CERF simulates siting decisions by dynamically representing suitable areas for different generation technologies with geospatial analyses (informed by technology-specific siting criteria, such as required mean streamflow per the Clean Water Act), and then choosing siting locations to minimize interconnection costs (to electric transmission and gas pipelines). CERF results are compared across three scenarios simulated by GCAM-USA: 1) a non-mitigation scenario (RCP8.5) in which conventional fossil-fueled technologies prevail, 2) a mitigation scenario (RCP4.5) in which the carbon price causes a shift toward nuclear, carbon capture and sequestration (CCS), and renewables, and 3) a repeat of scenario (2) in which CCS technologies are

  3. Surplus from and storage of electricity generated by intermittent sources

    2016-12-01

    Data from the German electricity system for the years 2010, 2012, 2013, and 2015 are used and scaled up to a 100% supply by intermittent renewable energy sources (iRES). In the average, 330GW wind and PV power are required to meet this 100% target. A back-up system is necessary with the power of 89% of peak load. Surplus electricity accrues at high power levels. Curtailing surplus power to a large extent is found to be uneconomic. Demand-side management will suffer from the strong day-to-day variation of available surplus energy. A day storage is ineffective because of the day-night correlation of surplus power during winter. A seasonal storage loses its character when transformation losses are considered because it can contribute only after periods with excessive surplus production. The option of an oversized iRES system to feed the storage is also not effective because, in this case, energy can be taken directly from the large iRES supply, making storage superfluous. The capacities to be installed stress the difficulty to base heat supply and mobility also on iRES generated electricity in the future. As the German energy transition replaces one CO2-free electricity supply system by another one, no major reduction in CO2 emission can be expected till 2022, when the last nuclear reactor will be switched off. By 2022, an extremely oversized power supply system has to be created, which can be expected to continue running down spot-market electricity prices. The continuation of the economic response -to replace expensive gas fuel by cheap lignite- causes an overall increase in CO2 emission. The German GHG emission targets for 2020 and beyond are therefore in jeopardy.

    Students in developing countries interested in STEM disciplines (science, technology, engineering & math) often choose majors that will improve their job opportunities in their home country when they graduate, e.g. engineering or medicine. Geoscience might be chosen as a sub-discipline of civil engineering, but rarely as a primary major unless there are local economic natural resources. The Institute of International Education administers the ExxonMobil Middle East and North Africa region scholars program designed to develop skilled students with a focus on geoscience and to build relationships with academic leaders by offering select faculty the opportunity to participation in the AGU fall meeting. At the Jordan University of Science and Technology (JUST), research in electrical engineering applied to medicine has potential links to geosciences. In geophysics, neural wavelet analysis (NWA) is commonly used to process complex seismic signals, e.g. for interpreting lithology or identifying hydrocarbons. In this study, NWA was used to characterize cardiac arrhythmias. A classification scheme was developed in which a neural network is used to identify three types of arrhythmia by distinct frequency bands. The performance of this scheme was tested using patient records from two electrocardiography (ECG) databases. These records contain normal ECG signals, as well as abnormal signals from atrial fibrillation (AF), ventricular tachycardia (VT) and ventricular fibrillation (VF) arrhythmias. The continuous wavelet transform is applied over frequencies of 0-50 Hz for times of 0-2s. For a normal ECG, the results show that the strongest signal is in a frequency range of 4-10 Hz. For AF, a low frequency ECG signal in the range of 0-5 Hz extends over the whole time domain. For VT, the low frequency spectrum is in the range of 2-10 Hz, appearing as three distinct bands. For VF, a continuous band in the range of 2-10 Hz extends over the whole time domain. The classification of

    A smart integration of electric vehicles into the future energy grid guarantees for matching energy demand and supply. To sufficiently integrate electric vehicles into the energy grid, it is necessary to maximize the vehicles' availability for intelligent charging processes. However, the availability highly depends on the motivation and skills of their users. Future drivers have to decide whether they want to initiate direct or intelligent charging processes. In case of intelligent charging processes, the systems require information about upcoming departure times and trip lengths. Inaccurate user predictions may reduce vehicles' availability for intelligent charging processes or may lead to insufficient battery levels. In the present paper, we investigate the influence of user variables on electric vehicles' availability for smart integration. We use data from psychological research that allows for comparing mobility predictions with actual mobility. We further technologically interpret data and display means to account for user variables in future charging scenarios. (orig.)

    In the current draft of the law on the reform of the support structures of hospital provision (German Hospital Structure Law) the future quality of provision is highly significant. Quality assurance measures are mandatory for hospitals. The Federal General Committee was legally charged with developing the relevant quality indicators for structural, procedural and outcome quality that are designed to form the criteria and the basis for planning decisions in the federal states. This involves a paradigm shift in quality assurance measures in hospitals. In the future, subject to the verified quality, this should have an influence on hospital planning, and the funding or regulation of hospital departments should also adhere to this prescribed quality. This review reveals the course of quality or quality assurance measures in medical services in Germany. The status of the institutions responsible for the quality of care in hospitals and the significance of quality indicators are explained.

    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.

    The ongoing transition of the German electricity supply toward a higher share of renewable and sustainable energy sources, called Energiewende in German, has led to dynamic changes in the environmental impact of electricity over the last few years. Prominent scenario studies predict that comparable dynamics will continue in the coming decades, which will further improve the environmental performance of Germany's electricity supply. Life cycle assessment (LCA) is the methodology commonly used to evaluate environmental performance. Previous LCA studies on electric vehicles have shown that the electricity supply for the vehicles' operation is responsible for the major part of their environmental impact. The core question of this study is how the prospective dynamic development of the German electricity mix will affect the impact of electric vehicles operated in Germany and how LCA can be adapted to analyze this impact in a more robust manner. The previously suggested approach of time-resolved LCA, which is located between static and dynamic LCA, is used in this study and compared with several static approaches. Furthermore, the uncertainty issue associated with scenario studies is addressed in general and in relation to time-resolved LCA. Two scenario studies relevant to policy making have been selected, but a moderate number of modifications have been necessary to adapt the data to the requirements of a life cycle inventory. A potential, fully electric vehicle powered by a supercapacitor energy storage system is used as a generic example. The results show that substantial improvements in the environmental repercussions of the electricity supply and, consequentially, of electric vehicles will be achieved between 2020 and 2031 on the basis of the energy mixes predicted in both studies. This study concludes that although scenarios might not be able to predict the future, they should nonetheless be used as data sources in prospective LCA studies, because in many cases

    Following expiry of the coal policy agreement dated 13{sup th} March 1997 at the end of 2005 a basic discussion of the future of the German coal mining industry began in 2006 and culminated on 7{sup th} February 2007 in the historic decision to cease production in 2018 together with a revision of the decision in 2012. Despite the unclear future prospects in 2006 the retrenchment process in the German coal mining industry continued with further reduction of production and job cuts. The remaining eight collieries produced 21.4 mill. t coal units. The total sales of German coal and coke in 2006 amounted to 22.4 mill. t coal units and were thus 4.4 mill. t coal units less than in the previous year. By contrast the total German coal market in 2006 increased by 1.1 mill. to coal units (+1.7%) to 64.0 mill. t coal units. About one third of the German coal market was supplied with German coal, two thirds with imported coal. Deliveries of the German coal mining industry to power stations fell by 9.9% to 18.3 mill. to coal units. The steel industry reduced its purchases by 2.4 mill. t coal units (39.1%) to 3.7 mill. t coal units. The number of employees in the German coal mining industry fell by 2,267 to 32,453 between the beginning and the end of 2006. (orig.)

    The German Federal Government published its energy concept in September 2010 with a description of the road into the era of renewable energies. Therefore, the future renewable energy installed in Germany is expected to consist mostly of wind and solar, which are subject to intermittency of supply and significant fluctuations. The growing portion of energy generation by fluctuating sources is turning to a big challenge for the power plant unit commitment and the investment decisions as well. In this thesis, a fundamental electricity market model with combined modeling of these two aspects is developed. This model is subsequently applied to the German electricity market to investigate what kind of power plant investments are indispensable, considering the steadily increasing portion of energy generation from fluctuating sources, to ensure a reliable energy supply in a cost-effective way in the future. In addition, current energy policy in Germany regarding the use of renewable energy and nuclear energy is analyzed.

For the period 1975-2003 we find that inflation news is the main driving force behind this comovement. When news is coming to the US market that future US...... in expected future inflation is the main reason for bond market comovement....... inflation will increase, there is a tendency that German inflation will also increase. This is regarded bad news for the bond market in both countries whereby bond prices are bid down leading to immediate negative return innovations and changing expectations of future excess bond returns.

    Full Text Available Due to the intermittent nature, renewable energy sources (RES has brought new challenges on load balancing and energy dispatching to the Smart Grid. Potentially served as distributed energy storage, Electric Vehicle’s (EV battery can be used as a way to help mitigate the pressure of fluctuation brought by RES and reinforce the stability of power systems. This paper gives a comprehensive review of the current situation of EV technology and mainly emphasizing three EV discharging operations which are Vehicle to Grid (V2G, Vehicle to Home (V2H, and Vehicle to Building (V2B, respectively. When needed, EV’s battery can discharge and send its surplus energy back to power grid, residential homes, or buildings. Based on our data analysis, we argue that V2G with the largest transmission power losses is potentially less efficient compared with the other two modes. We show that the residential users have the incentive to schedule the charging, V2G, and V2H according to the real-time price (RTP and the market sell-back price. In addition, we discuss some challenges and potential risks resulting from EVs’ fast growth. Finally we propose some suggestions on future power systems and also argue that some incentives or rewards need to be provided to motivate EV owners to behave in the best interests of the overall power systems.

    Over the past few months a number of studies on the future development of the electricity production costs associated with the various green electricity production technologies have been presented, contributing to the discussion on the costs of the energy turnaround and the consequent necessity to amend the German Renewable Energy Law (EEG). However, the calculation base used in these cost surveys deserves questioning. More preferable would be a broadly based model which also takes account of systemic effects. This should also provide the basis for political decisions on the further course of development of renewable energy.

  18. Structural problems in the German hospital system.

    Science.gov (United States)

    Krukemeyer, M G

    2004-09-01

    The German health care system has been based on the Hospital Financing Act, which the German government introduced in 1972. According to that, the federal states plan hospitals and make investments. The health insurance funds finance the operating costs. But now the Hospital Financing Act is obsolete, because both the health insurance funds and the federal states are in financial trouble and try to avoid the costs, which are nevertheless rising. In order to freeze costs, the legislators have introduced a new remuneration system, called DRGs (Diagnosis Related Groups), which will be mandatory from 2007 onwards. In this system, the treatment provided will be coded and remunerated on the basis of the primary diagnosis. Periods of hospitalisation and different remuneration systems will no longer be relevant. Transparency and quality will thus be promoted, and the upshot will be more competition among the hospitals. Hospitals that cannot meet quality standards will lose patients and will ultimately have to close. Other participants in the health care system, such as, for example, nursing staff, physicians, pharmacies, rehabilitaion centres and patients, will also be concerned in many ways. The consequences of the DRGs for the health care system, its future development and possible alternatives are discussed in this article.

First important publications in the 1950s and basic empirical investigations in the 1960s and 1970s were followed by the foundation of psychogerontological educational programs at the Universities of Kassel, Osnabrück-Vechta, Erlangen-Nuremberg and Heidelberg. With the foundation of the Deutsches Zentrum für Alternsforschung DZFA in 1996, German psychogerontology is now supported in a substantial way. In psychogeronotological research the Max-Planck-Institutions in Berlin and Munich play an influential role. Some major psychogerontological research projects and future developments in research are mentioned. Fundamental characteristics of the psychogerontological educational programs at the Universities of Kassel, Osnabrück, Erlangen-Nuremberg and Heidelberg are presented finally.

    After more than 25 years of development of nuclear power and almost 10 years of research and development in numerous areas of nonnuclear energy, there is now a good basis for judging the future prospects of energy technologies in the Federal Republic of Germany. The development of nuclear power has provided an important and economically advantageous new source of energy. Further efforts are needed to establish the nuclear fuel cycle in all stages and to exploit the potential of advanced reactors. In all other areas of energy technology, including energy conservation, new energy sources, and coal, economics has turned out to be the key problem, even at today's energy prices. Opportunities to overcome these economic problems through additional R & D are limited. There is some potential for special applications, and there are many technologies that could contribute to the energy supply of developing countries. In general, however, progress in energy conservation and the use of renewable energy sources will depend on the degree to which energy policy measures can improve their economic basis. For some technologies, such as solar thermal power stations and coal liquefaction, large-scale economic deployment cannot be foreseen today. Instead of establishing costly demonstration projects, emphasis will be put on improving key components of these technologies with the aim of having the most advanced technology available when the economic parameters are more favorable.

    The Deutsche Gesellschaft für Urologie (German Urological Association), established in 1907, was a German-Austrian medical society in which Jewish physicians held important positions. When the Nazis seized power in 1933, the Austrian Hans Rubritius was president of the society. The non-German presidency and the exclusion of Jewish colleagues from the professional society and medical practice led to a halt of the society's activities. At the same time in the mid 1930s, German urologists founded the Gesellschaft Reichsdeutscher Urologen (Association of Reichs-German Urologists) whose members aligned themselves with Nazi health policies and in turn received professional and personal benefits.

    1999-06-01

    The article discusses aspects of the establishment of a power exchange in Germany. For the time being, German traders in the energy sector and competitors in the European internal market for electricity perform exchange transactions on the stock exchanges in other European countries, as for instance on the recently established spot market APX in Amsterdam/Netherlands, which is open for traders from Germany and Belgium. Denmark will soon be admitted to the Scandinavian NordPool, so that German traders will have at their disposal a further spot market and a forward exchange. So far, initiatives for establishing a German power exchange got stuck in debates about the location, or inconsistency of goals, as the parties involved are at dispute about whether to establish a spot market first, or a forward exchange. The author nevertheless is of the opinion that the German government should not intervene but give time to the private sector to solve the conflicts. (orig./CB)

    Renewable resources will be an increasingly important issue for the chemical industry in the future. In the context of white biotechnology, they represent the intersection point of agriculture and the chemical industry. The scarcity and related increase in the price of fossil resources make renewable resources an interesting alternative. If one considers the production of bulk chemicals, it is evident that for this area besides the C sources, sugar and starch, new sources of raw materials must be opened up. One possible solution is to utilize lignocellulose both for materials and energy. This article discusses this interesting prospective for the future, particularly from the point of view of the German industry.

    The Square Kilometre Array (SKA) is the most ambitious radio telescope ever planned. With a collecting area of about a square kilometre, the SKA will be far superior in sensitivity and observing speed to all current radio facilities. The scientific capability promised by the SKA and its technological challenges provide an ideal base for interdisciplinary research, technology transfer, and collaboration between universities, research centres and industry. The SKA in the radio regime and the European Extreme Large Telescope (E-ELT) in the optical band are on the roadmap of the European Strategy Forum for Research Infrastructures (ESFRI) and have been recognised as the essential facilities for European research in astronomy. This "White Paper" outlines the German science and R&D interests in the SKA project and will provide the basis for future funding applications to secure German involvement in the Square Kilometre Array.

    In view of an ever-increasing infiltration of the German medical vocabulary by Britishisms and Americanisms, a linguistic attempt was made to categorize this phraseology as follows: more or less incorporated terminology, "internationalized" terms, identical translations, unnecessary use of English expressions instead of German synonyms, borrowing from the English with an alteration of the original meaning, and German neologisms on the basis of English vocabular material. Specimens from all these categories are enumerated.

Later, Metrical Phonology localized German stress close to the right edge of the stem, depending on the syllable weight. It will be shown that an algorithm based on a polytomous scale of syllable weight rather than a dichotomous one (heavy - light) is well able to predict German lexical stress. However, within the word class of proper names the algorithm fails....

  7. A Top-Down Spatially Resolved Electrical Load Model

    Directory of Open Access Journals (Sweden)

    Martin Robinius

    2017-03-01

    Full Text Available The increasing deployment of variable renewable energy sources (VRES is changing the source regime in the electrical energy sector. However, VRES feed-in from wind turbines and photovoltaic systems is dependent on the weather and only partially predictable. As a result, existing energy sector models must be re-evaluated and adjusted as necessary. In long-term forecast models, the expansion of VRES must be taken into account so that future local overloads can be identified and measures taken. This paper focuses on one input factor for electrical energy models: the electrical load. We compare two different types to describe this, namely vertical grid load and total load. For the total load, an approach for a spatially-resolved electrical load model is developed and applied at the municipal level in Germany. This model provides detailed information about the load at a quarterly-hour resolution across 11,268 German municipalities. In municipalities with concentrations of energy-intensive industry, high loads are expected, which our simulation reproduces with a good degree of accuracy. Our results also show that municipalities with energy-intensive industry have a higher simulated electric load than neighboring municipalities that do not host energy-intensive industries. The underlying data was extracted from publically accessible sources and therefore the methodology introduced is also applicable to other countries.

    . Microsimulation helps to overcome these problems. It compares policy options - actual reforms or reform plans - simultaneously and provides a comparable measure: the disposable income of model families. This article uses a type-case approach to investigate recent reforms of the German parental leave benefit....... Simulation makes those reforms comparable over time and across countries. Results show that the profile of the German scheme is changing from "general family" towards "dual-earner" support. Furthermore, the recent reforms make the German scheme converge towards the Swedish leave scheme. The recent reforms...... introduce a new concept of fairness and a focus on gender equality to German family policies....

  9. The Proto-Germanic n-stems

    DEFF Research Database (Denmark)

    Kroonen, Guus Jan

    The n-stems are an intriguing part of Proto-Germanic morphology. Unlike any other noun class, the n-stems have roots that are characterized by systematic consonant and vowel alternations across the different Germanic dialects. This monograph represents a diachronic investigation of this root...... variation. It traces back the Germanic n-stems to their Indo-European origin, and clarifies their formal characteristics by an interaction of sound law and analogy. This book therefore is not just an attempt to account for the typology of the Germanic n-stems, but also a case study of the impact that sound...

    Full Text Available There are 27 municipal libraries including the Central Public Library in Munich. The other important libraries in the city are Bayern State National Library, Maximillian University Library, a technical highschool library and the "Deutsches Musuem" Library. All these libraries are financed locally. The author introduces these libraries briefly and compares German libraries with Turkish libraries. He concludes that although theoretically there are not distinctive differences, in practice, buildings and their layout are better in Germany where more variety of services are offered. In Turkey standardization has not been realized yet. Turkey needs to computerize and network to improve the services offered in an efficient way.

    2012-08-15

    In the brochure under conideration, the Federal Environment Agency (Dessau-Rosslau, Federal Republic of Germany) reports on a sustainable electricity supply in the future. The costs and benefits of the transformation to 100% renewable energy sources are considered. The Federal Environment Agency concludes: A sustainable power supply requires the transition to a fully renewable energy supply. A full supply of electricity from renewable sources by 2050 is feasible technically. Thereby electricity from wind power and solar energy may play a central role in any ambitious expansion scenarios. The cost of power generation from renewable energy already are sunk. This trend will continue. Since the conventional power generation is more expensive in the future, renewable energy pays off more and more. Environmentally harmful subsidies and the lack of consideration of the social costs caused by the fossil and nuclear power generation massively distort the competition at the expense of renewable energy. The transformation of the energy system is worthwhile macroeconomically. The promotion of renewable energies avoids social follow-up costs caused by environmental damages and health related harms. Jobs are created. The regional value added is increased. It also improves the competitiveness of the fast-growing world markets for renewable energy technologies.

    2004-08-01

    Ludolph Brauer (1865-1951) played an influential role in the history of aviation medicine in Germany. The Treaty of Versailles had put a stop to the development of German aviation and associated medical activities at the end of World War I. Brauer deserves credit for restarting civilian aviation medicine in Germany in the 1920s, paving the way for it to flourish in the 1930s. As Medical Director of the Hamburg-Eppendorf General Hospital, Brauer established the first German Institute of Aviation Medicine (GIAM) in 1927 in affiliation with the Tuberculosis Research Institute with its two large pneumatic chambers. The GIAM was active in altitude research and the selection of pilots, as well as educating medical students in aviation medicine, training Aviation Medical Examiners, and exploring clinical applications of hypobaric and climatic therapy. Brauer was forced to retire in 1934 for political reasons as the GIAM came under the influence of the military; in 1939 it was made part of the Aeromedical Research Institute of the "Reichsluftfahrt" Ministry. Brauer was a co-editor of the journal Luftfahrtmedizin in the 1930s and 1940s. He died in Munich on November 25th, 1951.

  11. Is the future of utilizing wind power on sea?; Liegt die Zukunft der Windenergienutzung auf dem Meer?

    Energy Technology Data Exchange (ETDEWEB)

    Hamerak, Kurt

    2010-07-01

    The German Federal Government is determined to produce nearly 28 % of the total electric power from renewable energy sources up to the year 2020 in order to become independant from the energy supplies of the neighboring countries. The largest share of electrical energy generated in Germany results from renewable energy sources of wind energy. Currently, about 7 % of total gross electricity demand are covered by wind converters. Wind power stations are not base loadable. Thus, wind power stations cannot replace completely power plants powered by fossil fuels or nuclear energy. Under this aspect, the author of the paper under consideration examines the question of whether the future of wind energy use is on the sea.

    Energy Technology Data Exchange (ETDEWEB)

    Roennelid, Mats; Estevez, Nicolas Sebastian

    2007-12-28

    Due to the continued growth of installed area of Photovoltaic (PV) panels, Sweden will face a problem with electricity overproduction when PV panel production accounts for about 9% of total yearly electricity demand. Although this scenario might be over a decade away from happening it is important to look ahead now and make sure that our current practices and standards do not lead us into trouble in the future. This thesis explores the issue of Photovoltaic electricity overproduction in Sweden. The methodology of this work includes analyzing hourly weather data measured in five Swedish cities over several years and hourly electricity demand data of whole Sweden. A solar simulation program was written that would use the hourly weather data and calculate hourly insolation on tilted surfaces. The solar simulator output was used to calculate the area of PV when overproduction becomes a problem in Sweden and to explore the effect of surface tilt and orientation on yearly usable electricity production when the PV area grows beyond that point. This area is referred to as A{sub 0} in this text, and the best guess for Sweden was about 128 million square meters. Some scenarios with an installed PV area equal to different multiples of A{sub 0} were studied. Options of varying tilt and orientation angle could be evaluated to see which one would result in the highest yearly output. For example when the installed area equals 2 x A{sub 0} the highest output from the PV panels result from pointing the panels in the same way as with no overproduction. Only a 6% overproduction loss is suffered from doubling the Max Area of Zero Over-production and PV would be able to cover about 17% of the yearly Swedish electric demand. Beyond doubling of A{sub 0} the angles become less important. This is because as the overproduction becomes higher for the optimal angles the non-optimum angles which are able to avoid overproduction will still have comparable yield. However the best yields are

  13. De novo transcriptome of the Hemimetabolous German cockroach (Blattella germanica.

    Directory of Open Access Journals (Sweden)

    Xiaojie Zhou

    Full Text Available BACKGROUND: The German cockroach, Blattella germanica, is an important insect pest that transmits various pathogens mechanically and causes severe allergic diseases. This insect has long served as a model system for studies of insect biology, physiology and ecology. However, the lack of genome or transcriptome information heavily hinder our further understanding about the German cockroach in every aspect at a molecular level and on a genome-wide scale. To explore the transcriptome and identify unique sequences of interest, we subjected the B. germanica transcriptome to massively parallel pyrosequencing and generated the first reference transcriptome for B. germanica. METHODOLOGY/PRINCIPAL FINDINGS: A total of 1,365,609 raw reads with an average length of 529 bp were generated via pyrosequencing the mixed cDNA library from different life stages of German cockroach including maturing oothecae, nymphs, adult females and males. The raw reads were de novo assembled to 48,800 contigs and 3,961 singletons with high-quality unique sequences. These sequences were annotated and classified functionally in terms of BLAST, GO and KEGG, and the genes putatively coding detoxification enzyme systems, insecticide targets, key components in systematic RNA interference, immunity and chemoreception pathways were identified. A total of 3,601 SSRs (Simple Sequence Repeats loci were also predicted. CONCLUSIONS/SIGNIFICANCE: The whole transcriptome pyrosequencing data from this study provides a usable genetic resource for future identification of potential functional genes involved in various biological processes.

    In this study, the authors report on the development of English and German versions of the Adolescent Time Attitude Scale (ATAS). The ATAS consists of six subscales assessing Past Positive, Past Negative, Present Positive, Present Negative, Future Positive, and Future Negative time attitudes. The authors describe the development of the scales and present data on the reliability and structural validity of ATAS scores in samples of American (N = 300) and German (N = 316) adolescents. Internal consistency estimates for scores on the English and German versions of the ATAS were in the .70 to .80 range. Confirmatory factor analyses indicated that a six-factor structure yielded the best fit for scores and that the scores were invariant across samples.

    Diana Olegovna Dushkova

    2016-06-01

    Full Text Available The paper presents a concept of urban green infrastructure and analyzes the features of its implementation in the urban development programmes of German cities. We analyzed the most shared articles devoted to the urban green infrastructure to see different approaches to definition of this term. It is based on materials of field research in the cities of Berlin and Leipzig in 2014-2015, international and national scientific publications. During the process of preparing the paper, consultations have been held with experts from scientific institutions and Administrations of Berlin and Leipzig as well as local experts from environmental organizations of both cities. Using the German cities of Berlin and Leipzig as examples, this paper identifies how the concept can be implemented in the program of urban development. It presents the main elements of green city model, which include mitigation of negative anthropogenic impact on the environment under the framework of urban sustainable development. Essential part of it is a complex ecological policy as a major necessary tool for the implementation of the green urban infrastructure concept. This ecological policy should embody not only some ecological measurements, but also a greening of all urban infrastructure elements as well as implementation of sustainable living with a greater awareness of the resources, which are used in everyday life, and development of environmental thinking among urban citizens. Urban green infrastructure is a unity of four main components: green building, green transportation, eco-friendly waste management, green transport routes and ecological corridors. Experience in the development of urban green infrastructure in Germany can be useful to improve the environmental situation in Russian cities.

    The iron and steel sector is the largest industrial CO2 emitter and energy consumer in the world. Energy efficiency is key to reduce energy consumption and GHG emissions. To understand future developments of energy use in the steel sector, it is worthwhile to analyze energy efficiency developments over the past two decades. This paper analyses the development of the specific energy consumption (SEC) (measured as primary energy use per unit of product) in the German steel sector between 1991 and 2007. We found that the total SEC declined by 0.4%/year. Of this 75%, or 0.3%/year, is due to a structural change towards more electric arc furnaces (EAF). Energy efficiency improvement accounts for about 25% of the observed change in SEC, or 0.1%/year. Energy efficiency improvements are found, especially in rolling (1.4%/year). The net SEC of blast furnaces decreased due to increased top gas recovery by 0.2%/year per tonne iron. Improvements in other processes were very limited or non-existent. In basic oxygen furnaces (BOF) net SEC increased due to a 60% decrease in BOF gas recovery between 1993 and 2007. In EAF and sinter plants the SEC remained constant or, respectively, even increased by 9% between 1991 and 2007 per tonne sinter.

  19. [The boycott against German scientists and the German language after World War I].

    Science.gov (United States)

    Reinbothe, R

    2013-12-01

    After the First World War, the Allied academies of sciences staged a boycott against German scientists and the German language. The objective of the boycott was to prevent the re-establishment of the prewar dominance of German scientists, the German language and German publications in the area of international scientific cooperation. Therefore the Allies excluded German scientists and the German language from international associations, congresses and publications, while they created new international scientific organizations under their leadership. Medical associations and congresses were also affected, e. g. congresses on surgery, ophthalmology and tuberculosis. Allied physicians replaced the "International Anti-Tuberculosis Association" founded in Berlin in 1902 with the "Union Internationale contre la Tuberculose"/"International Union against Tuberculosis", founded in Paris in 1920. Only French and English were used as the official languages of the new scientific organizations, just as in the League of Nations. The boycott was based on the fact that the German scientists had denied German war guilt and war crimes and glorified German militarism in a manifesto "To The Civilized World!" in 1914. The boycott first started in 1919 and had to be abolished in 1926, when Germany became a member of the League of Nations. Many German and foreign physicians as well as other scientists protested against the boycott. Some German scientists and institutions even staged a counter-boycott impeding the resumption of international collaboration. The boycott entailed an enduring decline of German as an international scientific language. After the Second World War scientists of the victorious Western Powers implemented a complete reorganization of the international scientific arena, based on the same organizational structures and language restrictions they had built up in 1919/1920. At the same time scientists from the U.S.A. staged an active language and publication policy, in

    Every year CERN welcomes thousands of pupils from schools worldwide for a half-day visit to the Laboratory. However, since 2011 about ten selected students from Germany have been given the opportunity to experience CERN in much greater depth. They are fully sponsored by the German Ministry of Education and supported by an organising structure at TU Dresden - the Dresden University of Technology - led by Michael Kobel. It’s an investment that's paying off in Germany.   The German teachers who participated in the “Netzwerk Teilchenwelt” project, at CERN last week. “Netzwerk Teilchenwelt” is a project that involves 23 German universities, the DESY Laboratory, several schools and, of course, CERN.

    2004-10-01

    In many areas of nanotechnology, Germany can count on a good knowledge basis due to its diverse activities in nanosciences. This knowledge basis, when paired with the production and sales structures needed for implementation and the internationally renowned German talent for system integration, should consequently lead to success in the marketplace. And this is exactly the field of application for the innovation initiative "Nanotechnologie erobert Märkte" (nanotechnology conquers markets) and for the new BMBF strategy in support of nanotechnology. Until now, aspects of nanotechnology have been advanced within the confines of their respective technical subject areas. However, the primary aim of incorporating them into an overall national strategy is to build on Germany's well-developed and internationally competitive research in science and technology to tap the potential of Germany's important industrial sectors for the application of nanotechnology through joint research projects (leading-edge innovations) that strategically target the value-added chain. This development is to be supported by government education policy to remedy a threatening shortage of skilled professionals. To realize that goal, forward-looking political policymaking must become oriented to a uniform concept of innovation, one that takes into consideration all facets of new technological advances that can contribute to a new culture of innovation in Germany. And that includes education and research policy as well as a climate that encourages and supports innovation in science, business and society.

  12. A German Perspective on Security Research

    Prior to 2007, there was no coherent federal approach to conceptualise and fund security research in Germany. This changed with the initiation of the national program for civil security research, managed by the German Ministry for Education and Research (BMBF). Over the course of only four years a continuous build-up of national capacities on civil security was established to better protect German citizens, commodities and infrastructures against terrorism, organised crime and the effects of man-made and natural disasters.

  16. Consortium for Electric Reliability Technology Solutions Grid of the Future White Paper on Review of Recent Reliability Issues and Systems Events

    Energy Technology Data Exchange (ETDEWEB)

    Hauer, John F.; Dagle, Jeffery E.

    1999-12-01

    This report is one of six reports developed under the U.S. Department of Energy (DOE) program in Power System Integration and Reliability (PSIR). The objective of this report is to review, analyze, and evaluate critical reliability issues demonstrated by recent disturbance events in the North America power system. Eleven major disturbances are examined, most occurring in this decade. The strategic challenge is that the pattern of technical need has persisted for a long period of time. For more than a decade, anticipation of market deregulation has been a major disincentive to new investments in system capacity. It has also inspired reduced maintenance of existing assets. A massive infusion of better technology is emerging as the final option to continue reliable electrical services. If an investment in better technology will not be made in a timely manner, then North America should plan its adjustments to a very different level of electrical service. It is apparent that technical operations staff among the utilities can be very effective at marshaling their forces in the immediate aftermath of a system emergency, and that serious disturbances often lead to improved mechanisms for coordinated operation. It is not at all apparent that such efforts can be sustained through voluntary reliability organizations in which utility personnel external to those organizations do most of the technical work. The eastern interconnection shows several situations in which much of the technical support has migrated from the utilities to the Independent System Operator (ISO), and the ISO staffs or shares staff with the regional reliability council. This process may be a natural and very positive consequence of utility restructuring. If so, the process should be expedited in regions where it is less advanced.

    2015-06-01

    Germany is confronted with a lack of medical doctors and an increasing need for neurologists in particular. In order to recruit future doctors in neurology it is essential to attract young students when still at university. This article presents the first German national survey of medical students' acceptance of teaching methods in neurology. The participants evaluated teaching methods and examination formats and were asked about their preferences. The survey was based on a questionnaire distributed to 22 German medical schools and 1245 participating students. Interactive teaching methods, especially courses in practical examinations, clinical internships and bedside teaching were highly rated among the students. In contrast, multiple choice tests, as one of the most widespread examination methods, were poorly rated compared to practical and oral examinations. For most of the students it was not decisive, in which semester teaching of neurology took place, while the majority asked for additional and more intensive neurological education. The data give an overview of teaching of neurology in Germany and students' assessment of various approaches. The results should be utilized towards reorientation of future curricula that should aim at innovative and even more practically oriented teaching.

    This work reviews proposed safety criteria prepared by the German Bundesministerium des Innern (BMI) for future licensing of gas-cooled high-temperature reactor (HTR) concepts in the Federal Republic of Germany. Comparison is made with US General Design Criteria (GDCs) in 10CFR50 Appendix A and with German light water reactor (LWR) criteria. Implications for the HTR design relative to the US design and safety approach are indicated. Both inherent characteristics and design features of the steam cycle, gas turbine, and process heat concepts are taken into account as well as generic design options such as a pebble bed or prismatic core.

    2017-02-01

    German and Turkish-speaking patients were recruited for a chronic heart failure management program. So far little is known about the special needs and characteristics of Turkish-speaking patients with chronic heart failure; therefore, the aim of this study was to examine sociodemographic and illness-related differences between German and Turkish-speaking patients with chronic heart failure. German and Turkish-speaking patients suffering from chronic heart failure and insured with the AOK Rheinland/Hamburg or the BARMER GEK health insurance companies and living in Cologne, Germany, were enrolled. Recruitment took place in hospitals, private practices and at information events. Components of the program were coordination of a guideline-oriented medical care, telemonitoring (e.g., blood pressure, electrocardiogram, and weight), a 24-h information hotline, attendance by German and Turkish-speaking nurses and a patient education program. Data were collected by standardized interviews in German or Turkish language. Data were analyzed with descriptive measures and tested for significance differences using Pearson's χ(2)-test and the t‑test. A total of 465 patients (average age 71 years, 55 % male and 33 % Turkish-speaking) were enrolled in the care program during the study period. Significant differences between German and Turkish-speaking patients were found for age, education, employment status, comorbidities, risk perception, knowledge on heart failure and fear of loss of independence. The response rate could be achieved with the help of specific measures for patient enrollment by Turkish-speaking integration nurses. The differences between German and Turkish-speaking patients should in future be taken into account in the care of people with chronic heart failure.

  11. The electric field of the Earth after the occurrence of the February 14th, 2008, Ms = 6.7R EQ in Greece. Its implications towards the prediction of a probable future large EQ

    2008-01-01

    The electric field of the Earth registered by three monitoring sites (ATH, PYR, HIO) located in Greece, is investigated and analyzed after the occurrence of the Methoni EQ (14th of February, 2008, Ms =6.7R). The period of analysis is performed for 2 days (21st-22nd of February) and 7 days after the occurrence of the main seismic event. The obtained results suggest that the seismogenic area generates electrical signals denoting a specific epicentral area. This area coincides with the already seismically activated area. An estimate for the time of occurrence of this EQ is made by the application of the Oscillating Lithospheric Plate Model. The analysis of the seismic potential of the regional area suggests that the remaining stored seismic energy is capable of producing a large earthquake in the same area. The expected maximum magnitude (Ms) of a future earthquake which could take place in the same seismogenic area is estimated as Ms = 7.24R by the application of the Lithospheric Seismic Energy flow model.

    Martin, M; Fangerau, H; Karenberg, A

    2016-08-01

    The article discusses the consequences for neurology as a discipline which resulted from neurologists' participation in the crimes committed under National Socialism (NS). Chronologically, the current literature distinguishes mainly four overlapping stages: (1) a first phase was characterized by legal persecution and "denazification", which was also the time of the Nuremberg doctors' trial in which no neurologists were on trial. A detailed documentation of the trial for the German medical profession was published by Alexander Mitscherlich. (2) In the subsequent practice of wide amnestying and reintegration of former Nazi followers during the 1950s, neurologists were no exception as its elite continued in their positions. The year 1953 was the year of the Lisbon scandal, when chiefly Dutch representatives protested against the participation of Julius Hallervorden in the International Congress of Neurology. The newly founded societies, the German Society for Neurology (Deutsche Gesellschaft für Neurologie, DGN) and the German Society for Psychiatry and Neurology (Deutsche Gesellschaft für Psychiatrie und Neurologie, DGPN), unanimously supported their member. (3) The next period was characterized by a nascent criticism of the prevailing attitude of covering up the crimes committed by physicians during the Nazi period. The discovery of incriminating brain sections at various Max Planck Institutes brought neurology to the focus of the debate. (4) Since the 1980s and 1990s historians (of medicine) have been systematically examining medicine's Nazi past in a professional way, which resulted in a noticeable increase of knowledge. Additionally, a new generation of scholars provoked a change of mind insofar as they recognized medicine's responsibility for the crimes committed between 1933 and 1945. We expect that future historical research will further elucidate the history of neurology during the NS regime and have consequences for our current understanding of research

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

    Energy Technology Data Exchange (ETDEWEB)

    Pfaffenberger, W.

    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.

    第一辆混合动力汽车(HEV)诞生100多年了。近15年来,技术手段趋于成熟,在美国、日本和中国有很多混合动力乘用车投入使用。然而,在中国和美国,混合动力乘用车的市场份额依然很小。为使混合动力车辆更加成功,与传统内燃机车辆相比具竞争性,混合动力车就必须价格更便宜、性能更好。本文回顾了混合动力车辆的现状与发展趋势,并讨论了几种可以运行多行星齿轮排、多模式和全轮驱动的技术方案,这些技术方案将有助于实现混合动力车辆性能突破。这些方案对于将混合动力车辆技术从乘用车扩展到轻型卡车(LTs)和运动型多用途汽车(SUVs)十分重要。%The ifrst hybrid electric vehicle (HEV) was built more than 100 years ago. Over the last 15 years, the technologies have matured and many hybrid passenger cars are offered in US, Japan and China. However their market shares are stil very smal in both China and in the US. To make HEVs more successful, they must become more affordable, and have better performance, so that they can become more competitive compared with the traditional powertrain vehicles that only run on international combustion engines. This paper reviews the current status, and discusses several technology concepts to enable multi-planetary gear, multi-mode and al-wheel drive operations. These concepts likely wil help to achieve the needed performance breakthrough. These concepts are especialy important to extend the HEV technologies beyond passenger cars, to light trucks (LTs) and Sport Utility Vehicles (SUVs).

In addition, all the process was backed up to the end by the strong cooperation between the French and the German. Safety Authorities, which have a long lasting cooperation to define common requirements, which have to be applied to future Nuclear Power Plants. Furthermore an organization has been set up to elaborate common codes related to the EPR design, at the level of the French design and construction rules (RCC) or the German KTA safety standards, the so-called EPR technical codes (ETC). On the other side, the European utilities co-operate on a much broader basis for the establishment of European Utilities Requirements (EUR). These requirements are prepared by a group of European utilities that represent the major European electricity generating companies that are determined to keep the nuclear option open. The technical requirements specified in the EUR document define the boundaries in which future plants need to be designed in order to be acceptable for the needs of the utilities and in order to fulfill the basic requirements of competitive power generation costs and licensability in all countries represented in the EUR group.

  20. German Water Infrastructure in China: Colonial Qingdao 1898-1914.

    Science.gov (United States)

    Kneitz, Agnes

    2016-12-01

    Within the colorful tapestry of colonial possessions the German empire acquired over the short period of its existence, Qingdao stands out because it fulfilled a different role from settlements in Africa-especially because of its exemplary planned water infrastructure: its technological model, the resulting (public) hygiene, and the adjunct brewery. The National Naval Office (Reichsmarineamt), which oversaw the administration of the future "harbour colony"-at first little more than a little fishing village-enjoyed a remarkable degree of freedom in implementing this project. The German government invested heavily in showing off its techno-cultural achievements to China and the world and thereby massively exploited the natural resources of the mountainous interior. This contribution focuses on Qingdao's water infrastructure and its role in public hygiene and further area development. This article will not only use new empirical evidence to demonstrate that the water infrastructure was an ambivalent "tool of empire". Relying on the concept of "urban metabolism," this paper primarily traces the ecological consequences, particularly the landscape transformation of the mountains surrounding the bay and the implications for the region's water resources. When evaluating colonial enterprises, changes in local ecology should play a significantly greater role.

  1. Darwin: German mystic or French rationalist?

    Science.gov (United States)

    Ghiselin, Michael T

    2015-01-01

    The notion that Charles Darwin embraced the German Romantic tradition seems plausible, given the early influence of Alexander von Humboldt. But this view fails to do justice to other scientific traditions. Darwin was a protégé of the Englishman John Stevens Henslow and was a follower of the Scott Charles Lyell. He had important debts to French scientists, notably Henri Milne-Edwards, Etienne and Isidore Geoffroy Saint-Hilaire, and Alphonse de Candolle. Many Germans were quite supportive of Darwin, but not all of these were encumbered by idealistic metaphysical baggage. Both Darwin and Anton Dohrn treated science as very much a cosmopolitan enterprise.

  3. Oil pollution dangers on the German coast

    1984-03-01

    Helgoland waters in the German Bight are a vital wintering area for seabirds. As long as the discharge of waste oil and oily water is not completely avoided, large amounts of oil will continuously get into the sea. Therefore, the danger to the marine life, especially seabirds, increases. Helgoland presents the possibility of determining the extent and the effect of the oil pollution of the North Sea, since it is placed in the point of intersection of important steamship routes and also oil slicks drifted by the north-west winds along the German Bight. Seabirds are indicators for the quantity, the type and the temporal distribution of oil.

    Full Text Available The paper builds on our previous work in the field of bilingual education and/ or the process of natural bilingualisation of Slovak-German bilinguals in Slovak educational diasporas (educational islands in Austria. Starting point of psycholinguistic testing based on classic American Peabody Picture Vocabulary Test ( PPVT -III in its revised and German version presented in this paper is the thesis of initial lagging behind of linguistic (lexical, grammatical competence level of language L2 of bilingual children from preschool age in relation to various sociolinguistic variables, which, however, with age may, under certain favourable conditions nearly equal competence of monolinguals and in the area of reception of language even exceed it. For testing the reception levels of German mental lexicon we used two approximately equally large groups of respondents in a bilingual secondary grammar school in Bratislava and Vienna. The hypothesis of our research was that bilingual Austrian-Czech/Slovak bilinguals from Austria would achieve significantly better results than the Slovak-German bilinguals from Slovakia. The test results, however, surprisingly disproved our hypothesis and want to contribute to the debate on setting minimum standards of language competence of bilinguals as well as on optimisation of conditions of bilingual or monolingual education of not only Slovaks abroad.

    Modern motor vehicles are increasingly determined by electrical and electronic systems. Experts have estimated that, in future, 90% of all innovations in automotive engineering would not be possible without the use of electronic components and the corresponding software. But, when it comes to integrating all of these new electric components and drives, the developers come up against a natural boundary - the space available in the vehicle itself. Future developments in automotive engineering will therefore be largely determined by the spatial integration of electrical and electronic systems in the vehicle. This - besides other factors - is the main reason for the major importance of mechatronics in automotive engineering. (orig.) [German] Moderne Kraftfahrzeuge werden immer mehr von der Elektrik und Elektronik gepraegt. Nach Einschaetzung von Experten werden kuenftig 90% aller fahrzeugtechnischen Innovationen durch die Verwendung elektronischer Komponenten und entsprechender Software erst moeglich werden. Bei der Integration aller neuen elektrischen Komponenten und Antriebe stossen die Entwickler aber auf eine natuerliche Grenze - den im Automobil vorhandenen Bauraum. Die kuenftige Entwicklung im Automobil wird daher massgeblich durch die raeumliche Integration der Elektrik und Elektronik im Kfz bestimmt. Dies ist - neben anderen Faktoren - der wesentliche Treiber fuer die zunehmende Bedeutung der Mechatronik im Automobilbau. (orig.)

    Full Text Available Germany’s defeat in World War I and proclamation of the first German republic significantly influenced the change of the role of the army in the German state. At the stage of reorganization of the Kaiser’s army into the Reichswehr (1918–1921 the main result of this transformation became the creation of a new model of the German Army in which the principle of “distancing” the army from politics was replaced by new legislative and political realities that raised the question of inevitability of relationship between the army and the state. The Versailles Treaty and the Weimar constitution put forward the task of turning the German army into integral part of the state apparatus which led to losing its apoliticality. They also contributed to the emergence of Reich Ministry and the post of Reich Minister combined in one person the representative of the army and the state power. Besides, they helped to form a united German professional army and provided joint search of allies in the field of armaments by politicians and military men. The army tried to defend the old Prussian military traditions in terms of the German State called itself the Reich, and Weimar politicians sought to put the army under a parliamentary-presidential control. At the later stage of the Weimar Republic political generals will appear in the army, and important government positions will be taken by the representatives of the Generalitat. But the outcome of the force balance already at the stage of development of the temporary Reichswehr, when the real power in the army was in hands of the commander of the ground forces, and not of the Reich President and Reich Minister largely predetermined the strength of the conservative military elite in the future.

    Recently, the German Federal Government made the consequential decision to change its energy program. This not only as a result of the decision to shut down the existing nuclear power plants within the next few years, but also due to vital challenges like climate change and security of energy supply. The shift in the energy-technology paradigm from fossil fuel technologies to regenerative energies constitutes a major technical process but also new economic and social constellations. This paper focuses on hydrogen and fuel cell technologies in Germany. The institutional set up in this field is analysed and the new organizational actors are identified who have actively lobbied towards a political consensus. However, the experts in this field could not attain the required leadership in the public discourse on these technologies. It seems that an attractive guiding vision of a post-fossil energy future and a broad acceptance in daily use would have been major prerequisites for such leadership. (orig.)

  7. Is there a need for government interventions to adapt energy infrastructures to climate change? A German case study

    Science.gov (United States)

    Groth, Markus; Cortekar, Jörg

    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

    Electric vehicles that can't reach trolley wires need batteries. In the early 1900's electric cars disappeared when owners found that replacing the car's worn-out lead-acid battery costs more than a new gasoline-powered car. Most of today's electric cars are still propelled by lead-acid batteries. General Motors in their prototype Impact, for example, used starting-lighting-ignition batteries, which deliver lots of power for demonstrations, but have a life of less than 100 deep discharges. Now promising alternative technology has challenged the world-wide lead miners, refiners, and battery makers into forming a consortium that sponsors research into making better lead-acid batteries. Horizon's new bipolar battery delivered 50 watt-hours per kg (Wh/kg), compared with 20 for ordinary transport-vehicle batteries. The alternatives are delivering from 80 Wh/kg (nickel-metal hydride) up to 200 Wh/kg (zinc-bromine). A Fiat Panda traveled 260 km on a single charge of its zinc-bromine battery. A German 3.5-ton postal truck traveled 300 km with a single charge in its 650-kg (146 Wh/kg) zinc-air battery. Its top speed was 110 km per hour.

    Cretaceous Tendaguru palaeoecosystems. To put the German-Tanzanian Tendaguru expedition in perspective, a brief review of previous activities is given and future research objectives are outlined. Die berühmte Fossilfundstätte Tendaguru (Tansania, Ostafrika ist seit Anfang des 20. Jahrhunderts weltweit für ihre Dinosaurier aus der späten Jura-Zeit bekannt. Im Rahmen des Deutsch-Tansanischen Tendaguru Projekts fand im August und September 2000 eine Expedition in die Umgebung des Tendaguru-Hügels statt. Ziel der Expedition war es, umfangreiche Fossilaufsammlungen von Mikrovertebraten, Mikro- und Makroinvertebraten und pflanzlichen Fossilien durchzuführen und neue sedimentologische und stratigraphische Daten aufzunehmen. Unter Anwendung eines interdisziplinären Forschungsansatzes wurden mit den gesammelten Daten verschiedene, bisher kontrovers diskutierte Aspekte der Tendaguru-Schichten untersucht. Offene Fragen umfassten die genaue Alterseinstufung, eine Interpretation der Ablagerungsräume und die Rekonstruktion der Paläoökosysteme, in denen die Dinosaurier lebten. Die erste Auswertung der Geländedaten führte zu einem neuen Standardprofil für die Tendaguru-Schichten. Vorläufige biostratigraphische Ergebnisse, die auf Ammoniten, Charophyten und Palynomorphen basieren, sprechen für ein Ober-Kimmeridgium Alter der Nerineen Schicht, Unteres Tithonium für die Trigonia smeei Schicht und Untere Kreide (möglicherweise Valanginium bis Hauterivium für die Trigonia schwarzi Schicht. Die Lebens- und Ablagerungsräume der Tendaguru-Schichten reichten von sturm- und gezeitenbeeinflussten, küstennahen, siliziklastischen Barrieresystemen und Kalkooid-Barren über ausgedehnte Wattflächen bis zu sabkha-artigen Küstenebenen mit brackischen Seen und Tümpeln.

    Full Text Available This article presents the findings from a qualitative study of the German Wikipedia community, focusing on how people engaged with Wikipedia make sense of norms, collaborative practices and means of regulation within the community. The study highlights the strong focus on the quality of the end-product (the encyclopedia in the German community, stressing that article quality is seen as more important than the wiki-process as such. As the community has grown, an increasing number of rules and mechanisms have been deployed to resolve various issues and conflicts, however the interviewees do not perceive Wikipedia as being bureaucratic, but rather describe it as a “rule-governed anarchy”. The findings suggest that people contribute for a variety of reasons, yet point to reactions from and interactions with fellow Wikipedians as one of the strongest motivational drivers for participation.

    Full Text Available This review discusses the volume Debating German Heritage, a special issue of the journal Kunstiteaduslikke Uurimusi. This issue focuses heritage and art historical knowledge production in relation to nationalism, containing an introduction and six essays on a variety of subjects related to this main theme. The essays each approach heritage practices in the nineteenth century from different a perspective, ranging from canon formation to heritage preservation efforts at theatres of war. This review takes a closer look at each of the essays and studies the main contribution of the volume to the field of art history and heritage scholarship. Overall, this special issue offers interesting insights in the relationship between the dynamics of heritage preservation, art historical scholarship and nationalism from the point of view of Eastern and Central European scholarship with a ‘German connection’. In all, the essays are invariably well researched, often innovative in their approach and pleasant to read.

    Full-coverage maps on the distribution of marine biotopes are a necessary basis for Nature Conservation and Marine Spatial Planning. Yet biotope maps do not exist in many regions. We are generating the first full-coverage biotope map for the German Baltic Sea according to the HELCOM Underwater biotope and habitat classification system (HUB). Species distribution modelling is applied to create full-coverage spatial information of biological features. The results of biomass modelling of twelve target taxa and presence/absence modelling of three target taxa enabled the identification of biological levels up to HUB level 6. Environmental data on bathymetry, light penetration depth and substrate are used to identify habitat levels. HUB biotope levels were combined with HUB habitat levels to create a biotope map. Altogether, 68 HUB biotopes are identified in the German Baltic Sea. The new biotope map combining substrate characteristics and biological communities will facilitate marine management in the area.

    Although the significance of psychosocial issues of manned space flights has been discussed very often in recent literature, up to now, very few attempts have been made in North-America or Europe to provide astronaut candidates or spacecrew members with some kind of psychological training. As a first attempt in this field, a psychological training program for science astronauts is described, which has been developed by the German Aerospace Research Establishment and performed as part of the mission-independent biomedical training of the German astronauts' team. In contrast to other training concepts, this training program focused not only on skills needed to cope with psychosocial issues regarding long-term stays in space, but also on skills needed to cope with the different demands during the long pre-mission phase. Topics covered in the training were "Communication and Cooperation", "Stress-Management", "Coping with Operational Demands", "Effective Problem Solving in Groups", and "Problem-Oriented Team Supervision".

  3. Can German wine cooperatives compete on quality?

    Directory of Open Access Journals (Sweden)

    Schamel Guenter H.

    2015-01-01

    Full Text Available The paper analyzes how German cooperative wineries compete with private (i.e. non-cooperative wineries regarding reputation, quality categorization and varietal selection. Among the reasons why German cooperatives lag behind in terms of reputation for quality wine are organization principles of cooperatives and the difficulty to manage growers supplying grapes of different qualities. Cooperatives turn their supply of grapes into wine often classified as quality wine without much distinction. Conversely, privately owned wineries growing their own grapes may have more control over quality along their production chain and are able to produce more distinctive wines. In turn, they gain more reputation with final consumers with respect to quality. We analyze data for private and cooperative wineries from Germany. Our objective is to identify key differences in terms of reputation for quality wine production. Specifically, we look at interaction effects based on organizational form (cooperative vs. private and the German wine quality categorization (i.e. basic quality wine vs. Kabinett, Spätlese, or Auslese as well as varietal effects. We employ a hedonic pricing model to test the hypothesis that wines produced by private producers receive a reputation premium relative to cooperatives. Moreover, we hypothesize that private wineries receive a price premium relative to coopera- tives for other than basic quality wines and distinct varieties such as Riesling and Pinot Noir. The empirical analysis confirms both hypotheses. The estimated coefficients indicate that cooperatives are unable to gain quality premium for most quality cat- egories and gain price premiums only for non-distinct varieties such as Lemberger and Dornfelder. We can argue that German cooperatives are stuck in the low quality corner of the quality and variety spectrum and are currently not able to compete with private wineries in terms of quality. This result supports the observation

  5. Interaction of oxygen vacancies in yttrium germanates

    2012-01-01

    Forming a good Ge/dielectric interface is important to improve the electron mobility of a Ge metal oxide semiconductor field-effect transistor. A thin yttrium germanate capping layer can improve the properties of the Ge/GeO 2 system. We employ electronic structure calculations to investigate the effect of oxygen vacancies in yttrium-doped GeO 2 and the yttrium germanates Y 2Ge 2O 7 and Y 2GeO 5. The calculated densities of states indicate that dangling bonds from oxygen vacancies introduce in-gap states, but the system remains insulating. However, yttrium-doped GeO 2 becomes metallic under oxygen deficiency. Y-doped GeO 2, Y 2Ge 2O 7 and Y 2GeO 5 are calculated to be oxygen substoichiometric under low Fermi energy conditions. The use of yttrium germanates is proposed as a way to effectively passivate the Ge/dielectric interface. This journal is © 2012 the Owner Societies.

  6. [Propagating outsider methods at German universities].

    Ostendorf, G M

    1993-06-01

    According to the general-even legal-opinion and as I see it myself, the work at universities has to be carried out scientifically. Nevertheless, in the field of medicine it appears that at some German universities scientifically not generally acknowledged methods (outsider methods) are propagated uncritically. The violation of rules of scientific working methods, which obviously does not happen by chance, but rather systematically, can be proved in a number of publications. However, this can neither lead to the conclusion that German medical faculties do not work scientifically in principle, nor should it be regarded as a demand to stop the research into controversial methods of the scientifically not generally acknowledged medicine. In the face of the great number of scientifically not generally acknowledged methods as well as the limited funds and restricted research capacities at German universities, it would be sensible to continue the research only into unconventional methods which base on a plausible theory of effectiveness and where due to the results up to now a certain success can be expected.

  7. APPOSITIONS IN GERMAN AND IN TURKISH

    Directory of Open Access Journals (Sweden)

    Umut BALCI

    2012-03-01

    Full Text Available Turkish and German grammar books include word parts combined with secondary nouns. We call these, which exemplify the noun, as apposition. Turkish grammar books draw different conclusions from the term Apposition and it shows that it needs to be especially explicated. The apposition can be seen as resumption of same meaningful lexical units considered as a stylistic device providing a context-dependent credibility of expression, coherence, clarity, variation, adequacy and facility. We use many appositions consciously or unconsciously both in speaking and written language. When we compare the frequency of apposition usage with the relative clause, displaying the same function, apposition is surprisingly higher. According to statistical data, in every 100 sentences chosen from any text, there are about 30 appositions. Nevertheless, the apposition receives little attention especially in grammar teaching books, sometimes it even does not. Although it’s rare occurrence in the grammar books, we constantly encounter their syntactic, semantic and pragmatic dimensions in various types of texts. The reason why the Apposition in grammar teaching has received little discussionmight be a topic of other studies and we are not going to deal with this issue here. The purpose of this particular study is to reveal how much the Apposition is known as a grammatical category by our students and what can be done to increase the related awareness in this regard. Within the scope of this research study, the relative clauses present significance, as they are the most preferred and used ones among the Turkish learners who learn German as a foreign language. Due to their morphosyntactic structural difficulties, they are often memorized more than other forms of sentence. Moreover, they require more effort and in spoken form, they are economically impractical. However, it does not mean that theyarenotused or exaggerated in their usage because each mode of expression has

    2007-08-01

    Full Text Available History and memory appear to be increasingly important to discussions of European values and identity, as exemplified by references to ‘bitter experiences’ and ‘divided pasts’ in the draft EU constitution. The article takes recent suggestions that Europe could learn from German experiences of confronting multiple difficult pasts as its starting point, and considers critically what lessons those German experiences might in fact hold for ‘Europe’. It explores similarities and differences in the two integration contexts and their dominant approaches to, and assumptions about history and public memory. Specifically, it considers debates about the east-west division of the Cold War and about the place of communism and nazism in public memory. Contrary to common assumptions, the article argues that German experiences are not necessarily worth of European emulation.

    Full Text Available After consistently bad results in every PISA test (Programme for International Student Assessment and an accompanying prediction of lack of skills in its future workforce, Germany might be on track for losing out in international competition. Because of PISA’s overwhelming marketing presence, its results are a major political influence. The OECD PISA committee’s recommendations based on the results are challenging the fundamental structure of Germany’s three-tiered educational system, aiming to eliminate its segregational effects on social classes. In order to analyze PISA’s effects on German society from the angle of educational policy, this study compares the goals stated in its documentation with its effects on the public perception of Germany’s future workforce. Three fields of research are considered: Education as a concept for furthering society as a whole, assessment logic, and the educational system as a functional module of the nation state. The study will show that PISA’s test results are valid in indicating an urgent necessity to improve the teaching of basic skills, such as mathematics, reading, and writing. The interpretations of and recommendations based on these results, however, are reflecting a solely utilitarian view of educational systems as supplying human resources for industry.

    The German Cardiac Society is the oldest national cardiac society in Europe, founded on June 3, 1927, in Bad Nauheim by Dr. Bruno Kisch and Professor Arthur Weber. They were actively supported by Dr. Franz Groedel, who together with Kisch became co-founders of the American College of Cardiology in 1949. Both Groedel and Kisch would be proud to see the fulfillment of their visions and dreams, which was commemorated at the joint session of the two societies held during the 78th annual meeting of the German Cardiac Society in Mannheim, Germany. "It is ironic that their dreadful years in Germany and their loss to German Cardiology helped to contribute to advances in American and international Cardiology," said Dr. Simon Dack, American College of Cardiology president in 1956 and 1957. The legacy of Groedel might be reflected by his own words: "We will meet the future not merely by dreams but by concerned action and inextinguishable enthusiasm".
