In 1982 I connected an Anemometer to a Pet Computer and prospected for a wind power site.
My wife wrote the software.
I bought a prop with a 15:1 wind/tip speed ratio.
The guy who sold me the anemometer went on to be the project engineer at the Altamont wind farm in CA.
I came to the conclusion that wind power was not viable.
The wind has two big problems:
1) the wind can blow not hard enough
2) the wind can blow too hard
The energy available from wind is proportional to the wind speed cubed.
That shrinks too fast with low wind speed.
That blows up too fast with high wind speed. [machine must be shut down in high wind]
