A wind turbine is a rotating machine that converts the wind's kinetic energy into electrical energy.
James Blyth, inventor of the wind turbine, was born on April 4, 1839 in Marykirk, Scotland. In July 1887 he built a cloth-sailed wind turbine in the garden of his holiday home in Marykirk and used the electricity it produced to charge accumulators; the stored electricity was used to power the lights in his cottage, which thus became the first house in the world to be powered by wind-generated electricity.
Blyth was awarded a UK patent for his "wind engine" in November 1891. He later developed an improved model which served as an emergency power source at Montrose Lunatic Asylum for the next 30 years.

The Bahrain World Trade Center, a twin tower complex located in Manama, Bahrain, was completed on April 8, 2008. One of the most innovative features of the building is its integration of wind turbines into the design. The towers feature three large wind turbines, each 29 meters (95 feet) in diameter, which are mounted horizontally between the towers at a height of 95 meters (312 feet) above ground level. The turbines are designed to generate enough electricity to power about 300 homes each year, which helps to offset the energy used by the building. The incorporation of wind turbines into the design of the Bahrain World Trade Center was a pioneering effort to integrate sustainable energy solutions into modern architecture.
After being forced to quit school at 14 due to poverty, the Malawian teenager William Kamkwamba taught himself to build wind turbines out of trash. Using books from a local library, he transformed his village with electricity and became an international celebrity.
The tips of the blades of wind turbines move at speeds of up to 200mph (322 kmph).
Early wind turbines all turned anti-clockwise (as viewed from the front). Since 1978, however, changes in design mean they all turn clockwise.
Wind turbines are painted white to help them both blend in and to stand out. White or light grey helps them ‘blend' into the background, when the sky is cloudy. From the air the white color helps them stand out to planes. The same colour has two strikingly opposed purposes.
