They also are building more coal, gas, and nuclear than anyone else at epic yearly increases.

That they have the internal political means to get large infrastructure projects done is laudible - they can actually build transmission lines that make unreliable energy sources like solar and wind feasible. In the US that is effectively impossible due to the NIMBY legal situation.

That they lead in battery production is going to be pretty interesting to watch. I admit I was skeptical that current battery tech could be scaled up enough to make it financially doable, but China is very close to making me wrong on the topic. If they can be the first to truly seasonal storage that works without hand-waving games like pretending you can "just use another source" when you run out of storage I'll be very impressed.

They seem to understand that you need to back unreliable sources with reliable sources - and have the political means to build a coal plant that will sit idle 95% of the time.

No other country is close - it's parlor tricks at the moment. China seems to understand how energy works, and that you need a reliable grid to run an industrial economy. They are very much being pragmatic in how they are building out everything they possibly can. The West has forgotten this.
