So, is that supposed to be fast? When you consider the typical blade length for wind turbines, you see that the tip of the blade would easily go as fast as 100 mph to 180 mph depending on their RPM. A safe short answer to the question of "how fast does a wind turbine spin" would be "something around 100 RPM an up"! Image from Envato.
