Cheap solar, cheaper storage. Battery technology is now a very hot area, with a lot of R&D and constant improvements, like silicon chips in 1990s when the demand for computers started to turn truly massive. Now we have massive demand for EVs, large-scale storage, and the usual mobile device power.
I doubt technology is going to solve our environmental issues. I see this assumption all the time, that the same thinking that got us into these problems is going to get us out of them. Technology rarely delivers on its promises.
