Answer:
The cut-in speed of a wind turbine is the minimum wind speed at which the turbine begins to generate usable electrical power. Typically, this speed ranges from 3 to 4 meters per second (m/s) or approximately 6.7 to 9 miles per hour (mph). Below this wind speed, the turbine will not produce power as the wind is not strong enough to overcome the system's mechanical inertia and start the blades spinning at an operational rate.
