"The report analyses the attitudes of the citizens of the European Union to energy and energy technology issues." -- P. 3.
Since the early 2000s, energy and environmental issues have led to a marked increase in electricity production from renewable energy sources. Sustainable development and concern for future generations constantly challenge us to develop new technologies for energy production, as well as new energy usage patterns. Their rapid emergence can make these new technologies difficult to understand and can thus affect perceptions. Directed towards a broad audience, this book contributes to a better understanding of new electricity generation technologies. It presents the issues, sources and means of conversion using a general approach, while developing scientific concepts to understand their main technical characteristics. This revised and extended second edition presents current data characterizing the development of these renewable energy sources, covering emerging photovoltaic and tidal technologies, offshore wind power, and recent developments on the integration of these sources into the electricity grid. The emergence of self-production and self-consumption is also addressed. In addition, several exercises provide the reader with an opportunity to evaluate their understanding.
Energy Balances and Energy Accounting, an extract from the book Energy Terminology: A Multilingual Glossary, is a multi-lingual glossary of different terms and concepts related to energy and energy accounting. The definitions covered in this book include general terms and concepts in the study of energy, energy balances, additional energy accounting terms, and energy use. Concise yet very informative, this book is a good reference for those who are studying or working in the field of physics, those who do not have English as their primary language, and those working in the countries that use French, Spanish, and German as their national language.
Energy Modelling Studies and Conservation documents the proceedings of seminar of the United Nations Economic Commission for Europe held in Washington D.C., on 24-28 March 1980. The volume begins with a Seminar Theme Paper that identifies background policy issues that lead to modeling; discusses points of view involved in energy policy modeling; defines the context of a set of energy conservation problems or questions being analyzed; and provides a forward-looking view of the subject and its problems. This is followed by 54 papers that are organized into three main topics: (1) energy models of major interest to individual countries; (2) the interaction between energy conservation measures and the economy; and (3) the international aspects of energy conservation models. The papers on Topic 1 cover forecasting methodologies, demand and conservation studies, and electricity and supply studies. The papers on Topic 2 present the experiences in countries such as Norway, UK, the USSR, and US. The papers on Topic 3 include studies on energy conservation policies in France, Germany, and Italy; and the MARKAL multi-period linear programming model for joint research and development in the field of new energy technologies of the 17 countries of the International Energy Agency.
Philosophy of logic and language, and of meaning and communication are central to this volume. The discussion of these issues involves analytical approaches, including semantics and semiotics, philosophy of science, mathematical logic, phenomenology, hermeneutics and some aspects of philosophical anthropology and aesthetics. Philosophy of the Absolute also belongs to this broad repertoire of philosophical problems and disciplines. A number of problems and viewpoints derive from the metaphysical system; any relativistic view on ethical values, for instance, makes sense in relation to some absolute. Metaphysical system building may have come to an end, but after all it belongs to philosophy to remind us of our past.
This timely volume provides a comprehensive review of current technology for all ocean energies. It opens with an analysis of ocean thermal energy conversion (OTEC), with and without the use of an intermediate fluid. The historical and economic background is reviewed, and the geographical areas in which this energy could be utilized are pinpointed. The production of hydrogen as a side product, and environmental consequences of OTEC plants are looked at. The competitiveness of OTEC with conventional sources of energy is analysed. Optimisation, current research and development potential are also examined. Separate chapters provide a detailed examination of other ocean energy sources. The possible harnessing of solar ponds, ocean currents, and power derived from salinity differences is considered. There is a fascinating study of marine winds, and the question of using the ocean tides as a source of energy is examined, focussing on a number of tidal power plant projects, including data gathered from China, Australia, Great Britain, Korea and the USSR. Wave energy extraction has excited recent interest and activity, with a number of experimental pilot plants being built in northern Europe. This topic is discussed at length in view of its greater chance of implementation. Finally, geothermal and biomass energy are considered, and an assessment of their future is given. Each chapter contains bibliographic references. The author has also distinguished between energy schemes which might be valuable in less-industrialized regions of the world, but uneconomical in the developed countries. A large number of illustrations support the text. Every effort has been made to ensure that the book is readable and accessible for the specialist as well as the non-expert. It will be of particular interest to energy economists, engineers, geologists and oceanographers, and to environmentalists and environmental engineers.
