Wind Power, part of "A True Book" series, explains why the wind blows, how it affects local communities, how wind power was discovered, how wind power is used today, and how wind power will affect the future. Petersen starts off simply, connecting readers with the wind as a "rustling sound a breeze makes as it moves through the trees." From that small start, the reader then discovers wind as a major part of meteorology and global health. Next, Petersen shows how the wind can be harnessed as a clean source of energy. Many of the more difficult words such as "turbines" and "generators" are included in a glossary at the end of the book. The book also includes a list of additional books, organizations, and online sites for more information. There is also an index for easy reference. This is a good book for school reports or readers who are interested in clean energy, or conservation. 2004, Children's Press, Ages 8 to 12.
