Isn't Virginia a huge coal-mining state? I'm surprised nuclear is that high of a percentage.

I recall visiting a coal-mining museum in some state that had a big coal industry, and it was amazing how optimistic and pro-coal the whole thing was. (Note that I said "amazing", not "surprising".)

There's some here, but most of the coal mining activity is further west. West Virginia is the biggest coal state on the east coast and second biggest in the US. Nice map here:

It looks like their electricity is absolutely dominated by coal.

Even though not much in mined in state, we're close enough to WV and others that it seems like it would still be the obvious source here. I'm not sure why it's not, although I'm glad!
