Wind turbine design is the process of defining the form and configuration of a wind turbine to extract energy from the wind. [1] An installation consists of the systems needed to capture the wind's energy, point the turbine into the wind, convert mechanical rotation into electrical power, and other systems to start, stop, and control the turbine.
Energy from wind, sunlight or other renewable energy is converted to potential energy for storage in devices such as electric batteries or higher-elevation water reservoirs. The stored potential energy is later converted to electricity that is added to the power grid, even when the original energy source is not available.
Windmill ship – wind energy conversion system ship or wind energy harvester ship propels itself by use of a windmill to drive a propeller. Wind-powered land vehicles. Formula AE – a solar and wind powered car. Initial startup is by solar power; as the car travels at faster speeds, strategically placed air intakes are designed to direct air ...
The passive yaw systems utilize the wind force in order to adjust the orientation of the wind turbine rotor into the wind. In their simplest form these system comprise a simple roller bearing connection between the tower and the nacelle and a tail fin mounted on the nacelle and designed in such a way that it turns the wind turbine rotor into ...
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 ]
They usually produce between 500 W and 10 kW, with some as small as 50 W. The Canadian Wind Energy Association considers small wind turbines to be up to 300 kW, [1] while the IEC 61400 standard defines them as having a rotor area smaller than 200 m 2 and generating voltage below 1000 Va.c. or 1500 Vd.c.

For a wind turbine, the power harvested is given by the following formula: = where is the aerodynamic power and is the density of the air. The power coefficient is a representation of how much of the available power in the wind is captured by the wind turbine and can be looked up in the graph above.
