I'd be happy if coal is only used for making steel, where we really will need it as coking coal for some applications. Maybe one can make steel these days without coal at all, I'm not sure. I remember when Carter had that coal gassification plan built in the Dakotas, I think it is still operating. Very dumb idea.
Replacing coal with NG has advantages of course, but also means fracking continues.
Some don't like fracking. Some don't like nuclear. Well, OK then.
