This is misleading, because China has no gas, and they use coal power as dispatchable source with lower capacity factor (similar to gas elsewhere).

Coal+gas electricity is basically the same fraction in China than in the US.

But countries like Germany or Spain are significantly ahead in this regard, with much higher fraction of electrical energy coming from solar/wind.

Burning natural gas instead of coal should result in about half as much carbon emissions theoretically, although methane leaks will narrow the advantage.
