Answer:
the wind blows the wing things around which turns a large motor that creates power
(Where do they find these people?)
The wind is captured by the blades of the wind turbine, which are air-foil shaped. The force drives the blades which are precisely angled by a computer system to make the most efficient use of the available wind. The rotating motion of the blades attached to the hub, drives a gearbox which increases the rotating speed from the hub. The output of the gearbox spins a 3 phase generator at high speed that is computer matched to the existing grid frequency, supplying it with power.
