Worldwide attention to environmental issues combined with the energy crisis force us to reduce greenhouse emissions and increase the usage of renewable energy sources as a solution to providing an efficient environment. This book addresses the current issues of sustainable growth and applications in renewable energy sources. The fifteen chapters of the book have been divided into two sections to organize the information accessible to readers. The book provides a variety of material, for instance on policies aiming at the promotion of sustainable development and implementation aspects of RES.

Renewable Energy is energy generated from natural resources - such as sunlight, wind, rain, tides and geothermal heat - which are naturally replenished. In 2008, about 18% of global final energy consumption came from renewables, with 13% coming from traditional biomass, such as wood burning. Hydroelectricity was the next largest renewable source, providing 3% (15% of global electricity generation), followed by solar hot water/heating, which contributed with 1.3%. Modern technologies, such as geothermal energy, wind power, solar power, and ocean energy together provided some 0.8% of final energy consumption. The book provides a forum for dissemination and exchange of up - to - date scientific information on theoretical, generic and applied areas of knowledge. The topics deal with new devices and circuits for energy systems, photovoltaic and solar thermal, wind energy systems, tidal and wave energy, fuel cell systems, bio energy and geo-energy, sustainable energy resources and systems, energy storage systems, energy market management and economics, off-grid isolated energy systems, energy in transportation systems, energy resources for portable electronics, intelligent energy power transmission, distribution and inter - connectors, energy efficient utilization, environmental issues, energy harvesting, nanotechnology in energy, policy issues on renewable energy, building design, power electronics in energy conversion, new materials for energy resources, and RF and magnetic field energy devices.

This book presents an overview of current renewable energy sources, challenges and future trends. Drawing from their longtime expertise and deep knowledge of the field, the authors present a critic and well-structured perspective on sustainable power sources and technologies, including solar, wind, hydrogen and nuclear, both in large and small scale. Using accessible language they provide rigorous technological reviews and analyze the main issues of practical usage. The book addresses current questions in this area, such as: "Is there enough biomass to make a difference in energy needs? Should biomass be used in Energy Generation?"; "How mature is battery technology? Will it finally become cost effective, and will it make a significant difference this next decade?"; "How big a role will small and modular nuclear power generation play in the coming decades?"; "What will be the influence of national tax policies?". No prior technical knowledge is assumed of the reader. It is, therefore, ideal for professionals and students in all areas of energy and power systems, as well as those involved in energy planning, management and policy. Presents a realistic and clear overview of the key sustainable energy technologies that will play important roles in the world’s energy mix and their impact on the current power infrastructure. Discusses key societal and economic topics related to the implementation of sustainable energy sources in a straightforward way. Covers a broad variety of sustainable and renewable energy sources, including hydrogen and bioenergy. It also explores key issues on small modular nuclear facilities, advances in battery technologies, grid integration, off-grid communities and the most recent topics in energy economics and policy.

La victoire de l'économie de marché sur l'économie planifiée, à la suite de l'effondrement du communisme soviétique en 1989, nous condamne à nous développer économiquement pour progresser socialement. Ce développement suppose la disponibilité de ressources énergétiques en quantité suffisante. Or, nous avons pris récemment conscience de l'existence de deux contraintes dont nous devons impérativement tenir compte : - la Terre est un espace restreint aux ressources limitées ; - l'activité de l'Homme peut provoquer un désastre climatique. Il est alors apparu que le seul développement qui soit acceptable est " durable", c'est-à-dire un développement "qui réponde aux besoins du présent sans compromettre la capacité des générations futures à répondre aux leurs ". En se focalisant sur la production électrique, l'ouvrage se propose d'analyser les énergies renouvelables - éolien, solaire, hydraulique, biomasse, géothermique - en tant que parties intégrantes du développement durable, et de clarifier leur rôle au sein du mix énergétique.
