Definition: Wind power
The amount of power available to a wind turbine depends on: air density, wind speed and the swept area of the rotor. While the power is proportional to air density and swept area, it varies with the cube of wind speed, so small changes in wind speed can have a relatively large impact on wind power.
- Wind power is the conversion of wind energy into a useful form, such as electricity, using wind turbines. By 2010, a single wind turbine can produce several MW of electric power.
