Betz limit: The theoretical upper limit to wind power's capacity
factor, that is to the percent of available energy that a wind
turbine can actually capture as usable energy. Capacity Factor:
The percent of theoretically available energy that is actually
converted to usable energy; a percentage comparing a "plant's
actual production over a given period of time with the amount of
power the plant would have produced if it had run at full
