You really need to get a clue McGrew...
Coal is one of many pollution sources from man... Cars, plastic factories, chemical factories, trains, cruise ships, deforestation, etc. We need to take action on all fronts and try to return this planet to a much healthier and better place for everyone. Yes, we need a global focus on all countries. But it all has to start somewhere. Why not here?
Nuclear is not the answer, it is incredibly dangerous and we have no real way to deal with the spent fuel. As global warming continues, out climate become more volatile and more hostile. As we all saw in Fukushima, bad things can happen when natural disasters come into contact with nuclear reactors.
Before you go off on new reactor technologies like PRISM reactors (aka integral fast reactors, aka liquid metal cooled nuclear reactor). The technology is not proven, it's only conceptual at this point. There are a ton of safety concerns and they may never be able to get it to work properly (liquid sodium suffers spontaneous combustion with water, produces a lot of hydrogen and is incredibly explosive. Explosive and radioactive are not a good combination). But I am open to the possibility provided we can make them safe (keep in mind that currently, there are not safe reactors in the world)
Think about this for a moment... What if every roof top in the US was solar? I'm not talking about solar panels, I am talking about solar shingles. The entire roof, direct and indirect, (panels could be used on flat roofs). All we would need to do is introduce a building code/rule that states all new construction must have a solar roof and all re-roofing must be solar. In 50 to 70 years, every roof top in the US would be producing electricity, far more electricity than we currently produce (but we would need it to power all the electric vehicles and electric trains)
