Originally published in 1979, provides a tour of the world of solar energy and asks two key questions: is solar energy the key to the future of our energy needs and what are the facts and potential of this source of renewable power. The book examines solar energy from the past to modern plans for designing domestic solar housing, and looks at the sites and the technology applied to harness the Sun's power, such as the energy potential of windmills and the equatorial oceans. Behrman reports on the progress of scientists and manufacturers in making solar energy a viable competitor in the energy market, and studies the projections of a future energy crop for energy plantations.
