Wind turbine schematic.
An important factor in how much power your wind turbine will produce is the height
of its tower. The power available in the wind is proportional to the cube of its speed.
This means that if wind speed doubles, the power available to the wind generator
increases by a factor of 8 (2 x 2 x 2 = 8). Since wind speed increases with height,
increases to the tower height can mean enormous increases in the amount of
electricity generated by a wind turbine.
