> The reason I'm skeptical of that framing is it implies coal production is being replaced by clean energy, rather than total energy production being increased.

I wasn't intending to imply that. It's entirely possible China might get to 90% renewable energy production without shutting down a single coal plant.

> Lots of countries announce decarbonization goals, but I will remain skeptical until the data show progress.

Sure, but that doesn't conflict with having more and more of your energy production being renewable.
