Wind power is the use of wind energy to generate useful work. Historically, wind power was used by sails , windmills and windpumps , but today it is mostly used to generate electricity. This article deals only with wind power for electricity generation.
The WENDI Gateway had two main components: a wind energy metadata clearinghouse and the wind energy WebGIS Application. The WENDI Gateway also provided pages about the basics of how wind energy works, lists of major turbine manufacturers, a list of renewable resource educational programs, and a page about wind energy's effects on wildlife.
Commonly known in the US and Canada as a "weathercock" because it behaves much like a traditional weather vane, moving with the direction of the wind (but also measuring wind speed).The Butler brand added improvements to the technology of windpumps in 1897, 1898 and 1905 [11] A 16 ft (4.8 m) diameter wind pump can lift up to 1600 US gallons ...
Wind turbine – a turbine that converts wind energy into mechanical energy. Windmill – a machine which converts the energy of wind into rotational energy by means of vanes called sails or blades. Windpump – a windmill used for pumping water, either as a source of fresh water from wells, or for draining low-lying areas of land.
In the event of skew winds the "wind pressure" on the swept area causes a yawing moment around the tower axis (z-axis) which orients the rotor. [1] The tail fin (or wind vane) is commonly used for small wind turbines since it offers a low cost and reliable solution. It is however unable to cope with the high moments required to yaw the nacelle ...
A wind turbine is a device that converts the kinetic energy of wind into electrical energy. As of 2020 [update] , hundreds of thousands of large turbines , in installations known as wind farms , were generating over 650 gigawatts of power, with 60 GW added each year. [ 1 ]

Wind-turbine blades in laydown yard awaiting installation. The primary application of wind turbines is to generate energy using the wind. Hence, the aerodynamics is a very important aspect of wind turbines. Like most machines, wind turbines come in many different types, all of them based on different energy extraction concepts.
