1) China consumes more coal than the rest of the world combined.
2) Environmental regulations in China range from "minimal" to "non-existent". Do you need sources on that as well?

Yes, China does produce a lot of solar but what percentage of electricity is that?

You are speaking in generalities and not using hard data. That is no way to analyze a problem.
I'm not sure why this is confusing.
I'm also not sure why people are modding down factual posts. That type of behavior is exactly what's given you President Trump.

By "bearing the brunt" you mean "having jobs"? Have you asked them whether they would rather have jobs or not?
Also, they know perfectly well that closing their coal mines doesn't mean that coal doesn't get mined and burned. It just gets mined and burned in other countries where environmental regulations are non-existent.
The simplistic "coal is bad" thesis has a) put a huge number of Americans out of work and b) made the global environment worse.
