What makes a windmill spin fast?

The combination of lift and drag causes the rotor to spin like a propeller. A series of gears increase the rotation of the rotor from about 18 revolutions a minute to roughly 1,800 revolutions per minute — a speed that allows the turbine’s generator to produce AC electricity.

What RPM do wind turbines spin at?

10 to 20 revolutions per minute
Wind power is generated by the force wind exerts on the blades of a turbine, causing the turbine’s shaft to rotate at a speed of 10 to 20 revolutions per minute (rpm).
