Want to go green? Go nuclear. While wind power and hydroelectric are the cleanest, they can only be located in certain regions. If yours is not one of those locations, then you have to rely on coal fired power plants.

Unfortunately, coal fired plants release 520 times more carbon dioxide than a nuclear plant. And while the specter of a melt down is always present, coal fired carbon dioxide is a given.

So, if you want to go green, it looks like nuclear power is the answer for now.
