They are growing all over the world at a phenomenal rate, but I think it just takes some amount of time. They have only been the cheapest option for a few years now.

And in the U.S., Republicans have done everything they can to hamstring the transition and destroy the billions of dollars invested by automakers into EVs prior to 2025. But even that can only postpone the transition.

Also they’re only the cheapest at the point of generation, you then need to transfer that energy where it’s needed, and when it’s needed (storage). Also manufacturing capacity for renewables infrastructure, vehicles, batteries, etc, etc, is constrained. And then there are products that can’t be substituted by renewables such as plastics, fertiliser, etc. So many factors. It can’t happen too soon, but it will take many decades.
