Environmental journalist Pahl (U. of Vermont) offers readers a timely crash course in five renewable energy technologies--solar, wind, water, biomass and biofuels, and geothermal--aiming to inspire individual and community action through abundant examples of energy independence projects around the world. The introductory chapter explores peak oil and other energy problems in the U.S., as well as government initiatives (and the lack thereof) that address them. The author then discusses the potential, the history, and (briefly) the technology of each renewable alternative, followed by case studies. Language is appropriate for a general audience, but community/urban planners and homeowners may find this book especially useful. Annotation ©2007 Book News, Inc., Portland, OR (booknews.com)
