what do you mean exactly when you say think economically, not individually? because we already know the entire world creating solar panels/batteries, as you seem to be implying is the way forward, doesn't scale: - we know that that effort would result in an uptick in carbon production (need to produce all this new stuff: factories, ship it everywhere, etc.) - we also know that as energy gets cheaper, people use more of it - there aren't enough rare earths to replace all transportation with EVs, and even if there were it's like 20% of emissions; this ignores rare earths needed for outside storage batteries/grid tech/... the only solution - happens to be economic - is massive shedding of consumption by basically the entire population of the earth, and if you think your standard of living won't decrease many-fold you aren't being realistic.
