It is a mixed blessing.. But technology is morally agnostic. In the other hand nuclear waste (and the potential for accidental contamination) is a large price to pay. I hear that fusion has broken at the experimental stage (laser confinement), now if only that could be scaled up, that would be a potentially game changing fix...

Or if there was a possibility of solid state battery storage...

But definitely, nuclear power has given us a boost to efficiency of energy production, which is essential for a modern civilisation.
