Don't know about the others, but Illinois permanently shut down (and demolished or repurposed the land) the majority of its coal power plants over the past couple decades.

Illinois gets about half its power from nuclear (we have 6 plants and 11 reactors), followed by natural gas at around 20%, and then about equal amounts of coal and wind, at around 10-15%.

So Illinois is actually a pretty decent place to build datacenters, from a clean power generation perspective.
