I'll kick this off by saying, I believe our future would be better off with a strong dependence on wind, water, and solar power.
At least in this country however, our grid is not capable of supporting that.
Currently in the USA, we are very near approaching the point of demand overcoming supply of energy.
This leaves us with some major issues, are costly nuclear plants, with their safe and green operation, worth the price to build and run? As opposed to cheaper and more harmful Coal and Gas operations.
My opinion is yes. The designs of modern plants waiting to be built are smaller and more cost efficient.
I'll explain the USA's current nuclear waste situation if anyone has any questions on that worrisome subject.
