Every dollar in solar/wind/etc is wasted since it can't support the population without falling back to coal and gas. Renewable are a crapshoot relying on new storage technology that doesn't exist to make then viable. Why not focus on something we can 100% guarantee will fix the issues instead of leaving it to chance?
It is not only a distraction, but pushing a non-viable technology reduces the credibility of everybody that is trying to solve the problem with technology.
Building new nuclear just usn't the most effective use of limited capital to reduce emmisions at this point.
