In recent years our usage and understanding of different types of energy has grown at a tremendous rate. The editor-in-chief, Cutler Cleveland, and his international team of associate editors have brought together approximately 400 authors to produce the Encyclopedia of Energy. This highly topical reference draws together all aspects of energy, covering a wealth of areas throughout the natural, social and engineering sciences. The Encyclopedia will provide easily accessible information about all aspects of energy, written by leading international authorities. It will not only be indispensible for academics, researchers, professionals and students, but also for policy makers, energy and environmental consultants, and all those working in business corporations and non-governmental organisations whose activities relate to energy and the environment.
