I strongly disagree. New nuclear designs can consume ALL the fuel, leaving a residual that will drop to background radiation levels in less than 100 years. Further, these designs make it physically impossible for a meltdown to occur. Finally thorium based reactors are even safer still and can be made very small (think 2 standard shipping containers) which will allow for a distributed power generation grid of much finer granularity.
This is the future, not wind and solar.
