"High-altitude winds between 1,640 and 3,281 feet (500 and 10,000 meters) above the ground are stronger and steadier than surface winds. These winds are abundant, widely available, and carbon-free.

"The physics of wind power makes this resource extremely valuable. “When wind speed doubles, the energy it carries increases eightfold, triple the speed, and you have 27 times the energy,” explained Gong Zeqi "

thx for the link! just spent the last hr reading about windmills. and although I live in a country full of them I've often wondered, but never really paused to ponder about the intricacies that go into windmill design. fascinating stuff!

I work with statistics and joined a wind power forecast project, so I have been reading papers on wind power generation for the past month. There's other more complex formulas that the one shared on the link, but that was the first I found not pay walled.
