Count me among the clueless. One of the things that's been percolating in my mind as more and more devices run on DC and batteries is when the electric grid as it currently exists will be an anachronism for its then-current (no pun intended) use cases. Your mention of conversions brought this to the fore.

I get that pretty much everything short of solar is turbine-driven, which if I recall correctly is why we have an AC grid (high-school physics was a while ago, so I don't remember why). Since solar is the only residential-scale generation option, at what point does it start making sense to keep small-scale (say, neighbourhood level) DC needs separate from the AC that industry is designed around? I can't imagine there's anything to be gained from DC-AC-DC conversion.
