We should be investing solar in lower income communities, as those people could really use cheaper utilities, and any saving they get would immediately go back into their communities.
Those who are most able to pay for it are those who are paying for the highest initial costs, lowering the costs for everyone else by improvements in the technology, and making it easier for others to adopt later. Early adopters take lots of risk on things not working out well, and learning what things can go wrong and how to fix them (at additional expense, too.)
This is much better than those who are least able to pay being made to shoulder the cost and risks of being early adopters.
That money should have been spent to fund R&D/capital expenditures to make cheaper electric vehicles and solar cells for everyone, TBH.
It kinda was, it's just that it was spend in China and the US government got the money back by putting tariffs on the imports.
The tariffs are paid by the importer, whose customers also gets a government subsidy paid for by the tariffs that the electorate is told are paid by the exporter, so they get to feel like they're getting a good deal and the voters get to feel patriotic, and why isn't my MSCI China investment doing better…
