Question

what is the maximum speed of a wind to run a wind mill to maintain the necessary speed of turbine of an electric generator?

Answer 1

In general, wind speeds are as follows: 8 kph (2 m/s) minimum is required to start rotating most small wind turbines. 12.6 kph (3.5 m/s) is the typical cut-in speed, when a small turbine starts generating power. 36–54 kph (10–15 m/s) produces maximum generation power.

Answer 2

80 m per second is that speed
