A windmill is a mill with sails or vanes which by the action of wind upon them drive machinery for grinding corn, pumping water, and so on.
Windmills were used in the east in ancient times. An Arabic document of the year 644 contains the first known reference to one. Piruz Nahavandi, a Persian Sasanian soldier who in that year assassinated the caliph Omar in the mosque at Medina was described as a Persian builder of windmills.
Nashtifan, a village in northern Iran, uses 1000-year-old windmills made of clay, straw, and wood as an energy source. The ancient windmills have served to protect the village from damaging winds and process grains for over a millennium.
In Europe windmills were first used in Germany and the Netherlands in the 12th century.
A wind turbine is a windmill-like structure specifically developed to generate electricity. The world's first-known structure by which electricity was generated from wind power was built by James Blyth in 1887 in the garden of his holiday cottage in Marykirk, Scotland.
Around the time of World War I, American windmill makers were producing 100,000 farm windmills each year, mostly for water-pumping.
The De Zwaan Windmill in Holland, Michigan is the only authentic Dutch windmill operating in the United States. It is not only a historic attraction, but also a functioning machine that produces healthy whole wheat flour for the local community and beyond.
In the Netherlands, the second Saturday in May is traditionally National Windmill Day.
The engineer William Kamkwamba was born in Malawi on August 5, 1987. At the age of 15 he taught himself how to build windmills out of junk from the scrap yard to provide electricity for his family. Later on he built another windmill to power water pumps to irrigate fields. He did all of this through library books, as his family couldn't afford schooling.
