Wind energy today is a booming worldwide industry. The technology has truly come of age, with better, more reliable machinery and a greater understanding of how and where wind power makes sense -- from the independent homestead to a grid-connected utility-wide perspective. Heightened concerns about our environment mean that this resurgence of interest in wind -- a natural and widespread power source -- is here to stay. Wind Power is the completely revised and expanded edition of Paul Gipes definitive 1993 book, Wind Power for Home and Business. In addition to expanded sections on gauging wind resources and siting wind turbines, this edition includes new examples and case studies of successful wind systems, international sources for new and used equipment, and hundreds of color photographs and illustrations.
