Wind power scales with the cube of wind speed and the square of rotor diameter — which is why turbines keep getting bigger and why a windy site is worth so much more. No turbine can extract more than 59.3% of the wind's energy (the Betz limit); real machines reach about 45%. Below cut-in and above cut-out speeds they produce nothing.

Governing equation

P = \frac{1}{2} ρ A v^{3} C_{p} = \frac{1}{2} (1.225) (6362) (10)^{3} (0.42) = 1.64 MW

Reading this result: In the ramp region power climbs with the cube of wind speed, so even a small gust adds a large jump in output.
