Wind Power

Wind has been used as a power source for over 5,000 years. Windmills weren't just decorations in idyllic country scenes, they were used for milling grain and irrigating crops. Now modern wind turbines are scattered throughout the United States. These giant sweeping machines harness the power of the wind and turn it into usable energy. This book explains how wind is turned into sustainable energy and the pros and cons of wind power as a viable energy source.
