Re: Nuclear gets my vote
You can't pile up that much coal near a plant. Google "Spontaneous Coal Fire" and "Coal Stockpile Fires". Even skipping over the fire isse, if you leave coal out long enough it oxidizes and weathers; bad stuff leaches out, nasty gasses are emitted, and the coal swells with water and becomes less efficient to burn. Plants in the US keep at most a few days available to lower their risk and keep their efficiency up.
