Right now it wouldn't be worth it for us to install roof solar as grid power is cheap.

:h I'm curious ... where is both grid power cheap and the air clean if there isn't a bunch of falling water or nuclear fission around?

For example, here in CA grid power is not cheap and the air is getting clean, but without much help from nuclear fission or falling water. I expect that solar and wind has something to do with our clean air. However, so far solar and wind ARE NOT bringing down the cost of grid power.

Right here in the Southwest - in probably the largest solar and wind farm area of the U.S. - the cost to charge EVs has nowhere to go but up unless EV owners throw up enough solar real estate on their roofs. What are the financing costs for decent sized roof solar panel systems, anyway? Are payback break-even points still several years out?

I'm not a fan of individual solar setups at personal residences. I'd rather see the grid still supplying the bulk of personal residence power - including EV charging - but with grid power becoming cheaper and cheaper as large solar and wind farms feeding the grid come on line more and more across the U.S.. IMHO, that's the most efficient way for non-fossil power to benefit the masses and Planet Earth -> use the huge grid system that is already in place but feed it with solar and wind generated energy. (My thouughts on solar and wind sourcing of power are assuming that nuclear fusion power is still a long way off, or impossible.)
