Wind turbine - Wikipedia

A wind turbine is a device that converts the wind's kinetic energy into electrical energy.. Wind turbines are manufactured in a wide range of sizes, with either horizontal or vertical axes. It is estimated that hundreds of thousands of large turbines, in installations known as wind farms, now generate over 650 gigawatts of power, with 60 GW added each year.
