The US may be the Saudi Arabia of coal but coal has very real problems when compared to nuclear:
The waste from coal means gigatons of carbon dioxide going into the atmosphere. There is also the fly ash, slurry, and all the rest of the stuff. The sheer quantities get to be overwhelming. Eighty rail cars a day of coal, each one weighing a hundred tons goes into a 1-gigawatt coal-fired plant, and that multiplies to 19,000 tons of carbon dioxide, every day. Compare that to one year of a 1-gigawatt nuclear plant, which puts out 20 tons of very dense nuclear waste that goes into dry cask storage. You know exactly where it is and you monitor it, and it's not doing anything bad. That's a pretty strong contrast.
