I dont know how relevant this is from grid level, but the Hotel Marcel refurbed a building with DC power. People point out how they use PoE for room lighting, and there are more benefits. https://www.smartbuildingstech.com/intelligent-building-syst...

A net-zero building next to a six-lane road next to a ten-lane highway. I'm not sure if the lighting in that building is the right thing to focus on.

By that argument you can never focus on anything, since there will always be a worse offender somewhere.

That's right: we should postpone all other attempts to improve our energy infrastructure till our network of highways is destroyed or at least reduced to 2 lanes everywhere.
