Wind power is the conversion of wind energy into a useful form of energy, such as using wind turbines to make electrical power, windmills for mechanical power, windpumps for water pumping or drainage, or sails to propel ships.
Distribution of wind speed
The strength of wind varies, and an average value for a given location does not alone indicate the amount of energy a wind turbine could produce there
High altitude winds
Power generation from winds usually comes from winds very close to the surface of the earth.
