That really depends on what you mean by clean. If you're just talking about active waste during power generation, solar has zero, while nuclear produces waste that is notoriously difficult to deal with, albeit in very small amounts. Things get wild when you talk about the waste created during construction, but it's not like nuclear plants grow naturally either.

I don't care much about what part of the life cycle produces the waste, emissions, deaths etc. As long as they're produced somewhere sometime, they matter. In terms of total life cycle nuclear has the smallest environmental footprint and deathprint per unit energy.
