Use of the energy in winds to produce power. Though wind is irregular and spread out, it contains tremendous amounts of energy. Sophisticated wind turbines have been developed to convert this energy to electric power. The use of wind-energy systems grew considerably in the 1980s and '90s. Germany today produces more wind energy than any other country. Some 15,000 wind turbines are now in operation in California. See also windmill.
