"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 "

adding over 1tw of solar per year deserves a lot of praise. That they make everything for the world requires more power. Focusing on this is usually a pretext for doing much less energy transition work than China does.

Please redirect praise from China to countries who actually deserve it; like France, Sweden, Norway, and Finland. It's just fucking wild to praise China, a country that gets most of their power from coal, for doing well on power generation while shitting on a country that has done more than them.
