Actually, fossil fuel power plants release more radioactive waste than nuclear ones.

Nuclear power really is a darn good solution to our energy problems, and is more feasible and entirely more humane than using less energy. Our growing energy demands are not just a result of us being spoiled, they are a direct result of our need to sustain more and more people. Cut down on the energy, and you quickly fund yourself cutting down on progress and on the welfare of the poor.

Progress has created a lot of problems, but we can't really slow down in any significant way. Our only hope is to use our momentum to find solutions.
