How much land, time, and money, per citizen, would it take to put down enough solar cells to generate each person's basic electrical supply? Is it less than $5K?
That said, we're hitting 2030 with ~20% of American electricity coming from solar and wind versus 40 to 60% under the IRA baselines. We may wind up in a long-term spiral where our adversaries have not only more manufacturing capability and structurally lower labour costs, but structurally cheaper energy, too.

$5500 in solar panels including a battery would be just enough to keep the AC on all summer, and that's being fairly high on the temperature, around 26.
So based on cost alone and not power draw, with the AC off you could comfortably power a fridge, PC, and water heater, I guess? But I'm talking out my ass here

It is also true that solar water heating has unpleasant failure modes.
The issue is winter: It gets down to -25c and there is very little sun (not that it would help due to snow on the panels). In January and February this year I generated a grand total of 5kWh :D
However my house is a new house, it's designed to modern building standards and has 30cm of PIR insulation in the walls and even more in the roof. There's just no way to properly renovate old buildings to be like that without basically rebuilding the whole thing. The actual cost of materials is not expensive though (for the west). In milder climates (UK I'm looking at you) there's really no reason all new houses cannot be net-zero.
Meanwhile, we have, in Europe a lot of buildings from late 19, early 20th century that are perfectly habitable today and often are ruined by modern standards that not respect old standards. For example basement addition that prevents the apartments from “breathing” and causes them to become damp.
On the global market, you can get the equipment for much less, the same inverter is a fraction of the cost that the UL listed American company version costs, the panels are a good bit less. But in the US, this stuff gets marked up pretty hard.
If your main load is for summer A/C, with a mild winter, the generation and usage line up much better.
It takes a lot more than $5K to build a system that can replace a household's energy use. For 24 hour coverage you need substantial battery capacity, too.
To cover theoretical EV charging it gets even more expensive.
Prices continue to come down, but it still takes a lot to actually replace all of a household's energy usage with solar.
diesel is widely used for things like shipping and other supply chain stuff, so expect knock-on price impacts.
semi-trucks might be viable electrically, none of the other options currently are.
it wouldn’t be impossible to electrify, but outside of a few specific intra-city corridors, no one has spent the capital to try.
Trucks will stop delivering trash (ex. China dollar store crap, lower margin non food items and a billion other nonessential items). Food prices go up, people will do without less desserts or fancy foods but enough deliveries continue with the fuel saved that no one starves.
Now imagine if we replaced only 10% of diesel trucks with electric. Hell just focus on the short haul trucks. That unburned diesel could have helped buffer the remaining fleet.
