Things that would screw up if the sun got blocked: all photosynthesizing life, the hydrological cycle (it would freeze solid), the atmosphere (it would precipitate out). Merely having a fallback power solution would be the least of our problems.

Except we could produce food using artificial light, melt water, and evaporate the frozen atmosphere.

  That list - especially the last item - would take orders of magnitude more power than has ever been available from any human-engineered source.

    I meant locally for local use, not globally. We’d basically be living on a sunless Mars except with a lot more resources.

      I'm not sure how you'd bootstrap any of the measures you describe in an environment of extreme environmental hostility and complete societal breakdown. Reads like futurism blind to practical reality.

  Yeah, in vast airtight geothermally heated caverns that don't yet exist, using a closed cycle ark-ship ecology that has neither been perfected nor really even seriously tried, and with an "outside" that would be as ferociously hostile to human life as the surface of Pluto. Good anime setting, not really a plausible human future.
