I've heard conflicting stories about that. On the one hand, the people from TerraPower seem to have a solution with a good ecobalance. It was featured in the documentary about Bill Gates. On the other hand, I've heard several people claim that renewables are much cheaper and have better ecobalances, but I haven't seen the evidence for it.

So I'm personally undecided and with my limited knowledge believe that investing in renewable energy and new, modern nuclear power plants seems to be the right solution. In any case, change needs to occur as soon and fast as possible. But I'd be interested in sources to better information, particularly the claims I've heard that the costs for nuclear power plants is too high.

Is there an unbiased,reliable source for looking up complete ecobalances for energy sources, including the whole lifespan and all manufacturing of components and their disposal?
