As we experience a significant increase in the price of petroleum, energy experts caution us to the coming of a time when easily accessed petroleum will begin to decline. The United States is confronted with the challenge of meeting current energy demands in the face of a declining and unstable energy supply. Alternative Energy systematically explores the most viable alternative sources of energy, discussing the technical, political, economic, and social feasibility of each technology in understandable terms. In addition, the book discusses the history of energy policy, as well as current policy. Intended for courses in energy and public policy, as well as for those interested in developing energy-efficient plans for sustainable communities, Alternative Energy will help laypersons become active participants in making future energy choices for their communities. Includes an interactive model of alternative energy mixes and estimated prices.
