German Wind Turbine? Let’s Do Some Math

The turbine presented here has blades that are 0.5 meters in length, and the average home requires 1.2 KW.

When we plug this into a wind power calculator, we learn that we’ll need an average wind speed of 37 mph.

Since the average wind speed in Germany is 11 mph and power is proportionate to the cube of the wind speed, the average German will need 38 of these to power his house.
