Since early recorded history, people have been harnessing the energy of the wind. In the United States in the late 19th century, settlers began using windmills to pump water for farms and ranches, and later, to generate electricity for homes and industry. Industrialism led to a gradual decline in the use of windmills. The steam engine replaced European water-pumping windmills, and in the 1930s, the Rural Electrification Administration's programs brought inexpensive electric power to most rural areas in the United States. However, industrialization also sparked the development of larger windmills, wind turbines, to generate electricity.
