What does the capacity factor of wind mean? - Energy Numbers

The capacity factor is the average power generated, divided by the rated peak power. Let's take a five-megawatt wind turbine. If it produces power at an average of two megawatts, then its capacity factor is 40% (2÷5 = 0.40, i.e. 40%). To calculate the average power generated, just divide the total electricity generated, by the number of hours.

Wind power - Centre for Alternative Technology

When you double the diameter of a rotor it makes the swept area four times as big. This is because the area of a circle comes from the square of the radius (A = π r²). A rotor with a 10 metre diameter will therefore capture one hundred times as much wind as one with a one metre diameter. This means that very small turbines can't capture much wind.
