We need to develop nuclear energy using Thorium technology:

I agree, thorium seems to have a lot of potential (pun intended!)
Also take a look at how new companies like Hyperion are repackaging the nuclear power plant using modern technologies:

I often point out that no US nuke plant has been designed or built since the development of the microprocessor. Think about that - the control system at Three Mile Island was a lot closer to that of a steam locomotive than to what’s inside an iPhone. OK, that’s hyperbole but you see my point - since that damned movie with Jane Fonda we’ve run not just walked away from nuclear power and it’s high time we revisited it, with 40 years of technology innovations in our toolbox.
