Solar is just one technology. Decarbonizing successfully requires still further huge investments in batteries, modular nuclear reactors, CO2 removal, zero-carbon steel production, aviation e-fuels, non-fossil plastics, etc. But yes, hopefully we've unlocked enough economic advantage with just that one technology to get us 90% of the way there just on the basis of economics. (If the current administration doesn't find some way to sabotage it.)

It's just a shame that they didn't end up enjoying the spoils very long. They had very good panels that were researched and produced in Germany but they got completely wiped out by cheap Chinese products
