Originally published in 1986, this book takes an inter-disciplinary approach to the options for energy in the future. Written in a clear, easy-to-read style, it proposes that future solutions should not be based solely on cost, given our plentiful energy resources, but on ecological, human and ethical considerations. The book features a quantittive review of energy sources, supported by numerous figures and tables, that includes such long-term solutions as nuclear fission and solar energy. The book allows engineers and students to easily weigh the pros and cons of all energy options to realistically plan for the future.
