Energy systems and sustainability Upplaga 1

Today energy and sustainability are areas of primary concern. "Energy Systems and Sustainability" provides a thorough introduction to the economic, social, environmental and policy issues raised by current systems of energy use, as well as describing their key physical and engineering features. The book begins with an introductory account of the present world energy situation. This is followed by chapters explaining basic energy concepts and describing the magnitudes and patterns of human energy needs. The central part of the book deals with the historical evolution and present status of the conventional fossil and nuclear fuelled energy systems that, along with hydropower and traditional biofuels, currently supply the majority of the world's commercial energy needs. A section on economics describes the basic methods by which the monetary costs of energy are calculated, and discusses the issue of the 'external' costs of energy production. The concluding sections then deal with the sustainability problems associated with both fossil and nuclear fuel use, and ways in which these might be ameliorated by various technological developments. The interdisciplinary approach of the book will appeal not only to specialists but also to non-specialist readers who wish to improve their understanding of these complex and increasingly important issues. This book will be an ideal companion to the forthcoming second edition of "Renewable Energy" by Godfrey Boyle, which deals with the different forms of renewable energy and how these can be utilised.
