China is Building 74% of All Current Solar and Wind Projects (ft.com) 87
Almost three-quarters of all solar and wind power projects being built globally are in China, says a new report that highlights the country's rapid expansion of renewable energy sources. From a report: China is building 510 gigawatts of utility-scale solar and wind projects, according to data from the Global Energy Monitor, a non-governmental organisation based in San Francisco. That compares with about 689GW under construction globally, GEM said.
A rough rule of thumb is that a gigawatt can potentially supply electricity for about 1mn homes. "China is [...] leading the world in global renewable energy build-out," the report said. "It continues to add solar and wind power at a record pace." China's expansion of clean energy sources is important for efforts to fight climate change, given the country's dominant role in global manufacturing.

The combination tends to work well.
True as long as you have good grid connectivity so you can ship wind power in from a distance, which China is also building. Dealing with these variable sources is getting better and better. Storage over 24 hour periods and possibly even weeks also seems to be moving towards being a solved problem with new technologies coming online. Find a mineshaft or a hill, lift a weight from the bottom to the top, then store it nearby. Lower it down when you need energy back. Alternatively, pump water out of an underwater concrete dome or pump water up a hill and so on. It's also possible to convert iron oxide into iron powder that can later be burned for energy. That's all before you start talking about more expensive but convenient solutions like batteries.
China will now have a vast amount of energy that they can start testing those solutions on as well as finding industrial processes that can run intermittently when there's super cheap energy available. That converts this from a tactical gain into a strategic one. Once those industrial processes are mostly based in China they can keep learning to optimize them at scale in a way nobody else will be able to.

If America fails then it will be because they did not spend enough on nuclear power. Consider that any nation considered a military "superpower" they must have nuclear powered aircraft carriers and submarines. That list is very short.

Sun shine is NOT more dependable than wind. The sun is guaranteed not to shine at night, every night. In windy places that are used for wind farms, the wind tends to blow constantly. West Texas is a great example, the wind rarely stops, and usually blows at about 30 mph. It does slow during the day, when the sun is shining, but picks up at night, when the sun is not shini

That's like saying that oxygen is one of the most toxic substances known to man, in its modification known as ozone. Phosphorus is not toxic; it is in fact one of the essential elements for life. The backbone of DNA molecules are phosphates; no phosphorus, no life.
And the amount of phosphorus in solar panels is absolutely trivial-- it's a dopant, about 100 ppm in the emitter of the cell, a layer roughly a micron thick. It is not "white phosphorus".
