Power Coefficient - an overview | ScienceDirect Topics
The efficiency, or power coefficient, of wind turbines is not constant, and depends on the wind speed.A power curve shows how the power of a wind turbine varies with the wind speed. A typical power curve is depicted in Fig. 4.7.Wind turbines cannot generate electricity for very low (insufficient torque to overcome friction) or extremely high velocities (they will be damaged).

Interesting energy facts: Is wind power efficient enough?
The main problem with wind energy is the fact that windmills operate at around 40 percent of maximum production level. This is very small compared with 90 percent for coal and 95 percent for nuclear power, and wind energy will have to become much more efficient in years to come in order to compete with fossil fuels and nuclear energy.
