"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 "

Switching to renewables makes a lot of sense from an economic and ecologic point of view but also geostrategically. Unfortunately, Western governments have pretty much lost the ability to act on those considerations. This is due to then being beholden to a few billionaires who would rather see civilisation as we know it end than accept a few percentage points revenue drop for a couple of quarters.
