>>One study suggested that overhead electric lines are the cheapest in the long run, except for initial capital costs.

There's something related going on in Germany: stretches of highways in which the right hand lane is equipped with overhead wires, like those over electric RRs. Electric trucks can run under these lines, picking up power using trapezes similar to what's used on the RRs, both to keep moving and to charge batteries for the non-highway portion of their trip. Again, the issue is initial capital costs - but they're doing this now.

Agreed on issues with the grid. My cohousing community ran smack into this when we tried to put solar carports over our non-garage parking areas - the utility doesn't have the capacity to interconnect so we can feed power in (PV panels) and out (car chargers). We've given them a good bit of money so they can run a study to figure out what's possible - and for how much.

I expect that there's a lot of this going on across the country.

Working remotely is quite possible with a lot less than 25 Mb/s. If you are using, say, OpenVPN, and running RDP over that, it's possible to work remotely at a PC that's either in the office or in the cloud with under 2. The only slowdown comes when you need to print something really big right where you are. I'm up on this because I semi-retired from development into IT for a small financial firm. I found the simplest way to protect client data was to never let it out of the office (so everyone had remote connects to their office PCs) - which worked fine over DSL speeds.

Finally, I 100% agree that it's time to move a lot of manufacturing back to this continent - and I'd argue that presenting "build back better" as a way to bring production jobs back home (albeit of a lower number due to automation) is a winning strategy for the dems.
