Nuclear energy is the cleanest energy form we have, besides solar.
And solar is intermittent. And works well only where there is a lot of sun.
The best way and a necessary way to replace fossils is to use nuclear.
Even the IPCC and James Hansen have realized that.
Saying no to nuclear is being very cynical and a hypocrite, if you are informed, and truly believe fossils and CO2 to be the major threat to our future. You have to make up your mind.
