"Clean Coal" is a meaningless marketing term. Unless you specify what that means. (It used to mean CCS - which doesn't exist at scale - or more efficient coal plants - which probably only makes a very minor difference, because they're still terribly inefficient.)

I know. I want it called out on the graph.

Since "Clean Coal" is more about marketing and some token gestures at carbon capture, it is already represented on this list.

But it is very surprising that hydro, wind and solar aren't on this list. It is a non-trivial component of the total power production of both the US and Europe.

What is “clean coal” other than nice sounding words?

That is for the "Clean Coal" with scrubbers and such that is used in the US and Europe. The coal numbers would look much worse if we were talking about plants in China.
