what do wind turbines do
A wind turbine is a device that converts kinetic energy from the wind into electrical power. The term appears to have migrated from parallel hydroelectric technology (rotary propeller). The technical description for this type of machine is an aerofoil-powered generator.nshore wind turbines are installed in low wind speed areas and getting higher and higher towers. Usual towers of multi megawatt turbines have a height of 70m to 120m and in extremes up to 160m. All turbines are rotating with a speed, that the blade tip speed reach 80 m/s to 90 m/s.
