These points may have been made earlier but I'll take the chance of pointing out:

Nuclear Plants create waste heat, but do not create greenhouse gases.
All fuel plants create waste heat AND greenhouse gases.

There are ways to process and store nuclear fuel byproducts, there are simply no 'perfect' ways to do so.

Many countries are well along the nuclear path, France chief among them. This is out of necessity.

The one sure way to foster energy conservation is to make energy expensive. This is happening naturally, but in the light of global warming, it might be a good idea for a global energy tax ("Yeah, right!" says China).
