The real question is "why are nukemen so desperately against renewables (and therefore by default in favor of fossil fuels)?" The all-nuclear future had its moment in the sun in the 70s and has been comprehensively lapped. Only France came close.

the machines that convert the energy, store it and distribute it are not. Minerals have to be mined, machines build, transported, installed and then disposed off

This is of course also a valid argument against nuclear power.
