Also if we're planning for the long term; wind and solar sound like bad options for going into major global catastrophes like large asteroid hits or a nuclear war. It'd be better as a matter of principle to be using systems that can cope with massive climate disruptions. I like to bring up https://en.wikipedia.org/wiki/Year_Without_a_Summer - an event like that will happen sooner or later and it'd be pretty rough if we've all gone too heavy with solar.

One of those hopefully-you-don't-need-it concerns but it is starting to become a more pressing with the uptick in wars and unrest that seems to be going on.
