> Solar is good during the day, but it doesn't work at night.
That old phrase about the sun never setting on the empire or whatever comes to mind.
Grid interconnection can in fact provide solar energy all day.
And storage's insufficency back then is debatable. Sure the batteries were less volume-efficient but that just means more of them. However, electrical demand was both lower than now, and suddenly investing a lot into both solar and storage would *also* have led to improvements we've since seen, except much faster since there would have been a meaningful amount of investment in the matter by someone other than random companies and the odd university.
> GNUclear reactor in my backyard was practical prior to the 1980s, but nuclear isn't allowed?
Transport of nuclear fuel is needlessly hazardous (great opportunity for theft and misuse) and compromises eventual autarky (so long as fusion isn't figured out) as it cannot be found everywhere in sufficient quantities (encourages foreign capitalist abusers).
> baseload
That is based on an obsolete view of grid production that is largely due to the fact that several non-solar/storage technologies *cannot* be shutdown or brought back up quickly, reasonably, safely or cost effectively so they have to *always* be working to at least some degree. It's a way to cope with technological limitations, not an inherently necessary or good way to meet energy demand.
Even hydro-electric dams/storage demonstrate some inflexibility in requiring minutes to adjust product or turn off.
