Much as i dislike China i feel they are pragmatic. I don't know if it's justified but i always give them the benefit of the doubt that they don't do stupid things for no good reason. Unlike Western nations who have to please voters and look good, China has no such constraints and are far more transactional. They don't care about climate emissions. At all. If they think something will be good for them and their economy, they will do it. Another thing is that they take big risks, again they are beholden to nobody so they can. I think the way forward is to be realistic and honest. If renewables are cheaper we should go for them, why not? It's free. If not, not. Frankly having rolling blackouts in california is not a great argument for having more renewables, unless i'm missing something. It might be something for politicians to boast about next time they jet acrosss the world to attend self serving climate summits, but it doesn't help ordinary people. More fossil power plants would be more reliable then renewables. OT but Trump has a special dislike for green energy and i don't understand why, but it's obvious that if it can't compete, or come at least close to fossil fuels and nuclear then that should be fully acknowledged.
If i'm wrong about China and competely misreading the situation in california please let me know.
