What is a wind turbine and how it works? ACCIONA

WHAT IS A WIND TURBINE? A wind turbine is a device that converts kinetic energy from the wind into electricity. The blades of a wind turbine turn between 13 and 20 revolutions per minute, depending on their technology, at a constant or variable velocity, where the velocity of the rotor varies in relation to the velocity of the wind in order to reach a greater efficiency.

Small Wind Electric Systems Department of Energy

Wind turbines convert the kinetic energy in wind into clean electricity. When the wind spins the wind turbine's blades, a rotor captures the kinetic energy of the wind and converts it into rotary motion to drive the generator. Most turbines have automatic overspeed governing systems to keep the rotor from spinning out of control in very high winds.
