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.

The wind facilities are used to provide electricity to isolated locations and utility companies increasingly buy surplus electricity.
Wind power, as an alternative to fossil fuels, is plentiful, renewable, widely distributed, clean, produces no greenhouse gas emissions during operation and uses little land. Any effects on the environment are generally less problematic than those from other power sources. 83 countries around the world are using wind power on a commercial basis. The monetary cost per unit of energy produced is similar to the cost for new coal and natural gas installations.

Power management techniques are having excess capacity storage, dispatchable backing supplies (usually natural gas), storage such as pumped-storage hydroelectricity, exporting and importing power to neighboring areas or reducing demand when wind production is low.
