The provision of sustainable energy supplies for an expanding and increasingly productive world is one of the major issues facing civilisation today. Renewable Energy examines both the practical and economic potential of the renewable energy sources to meet this challenge. The underlyingphysical and technological principles behind deriving power from direct solar (solar thermal and photovoltaics), indirect solar (biomass, hydro, wind and wave) and non-solar (tidal and geothermal) energy sources are explained, within the context of their environmental impacts, their economics andtheir future prospects.Together with its companion volume, Energy Systems and Sustainability, this book provides both perspective and detail on the relative merits and state of progress of technologies for utilizing the various 'renewables'. The analysis considers emissions, sustainability, cost implications and energysecurity, as political and economic pressures move society towards a low-carbon future. From an overview of basic energy conversion processes, through a discussion of the individual renewable sources, to a concluding examination of the prospects for their integration into national and internationalnetworks, this book provides a valuable insight into prospects for the renewables.Online Resource CentreThe Online Resource Centre to accompany Renewable Energy features:For students:* Self-assessment questions.* Links to further information and up-to-date energy statistics.For registered adopters of the book:* Figures from the book in electronic format.
