I put a huge amount of personal energy into windmill electrical
generation between 1982 and 1984.

Your results are very dependent on the wind in your area.

The wind power available is proportional to the cube of the wind
speed.
If the wind is too low, you shut down.
If the wind is too high, you shut down.
If the wind is just right, you convert power.

The Seattle are is a terrible place for wind generation.
The wind is mostly too high or too low.
