I've seen these questions many times before, but no one seems to have an answer. It seems like the governments (and car companies) are just blindly pushing this through, and hoping it'll all get sorted out in the end. I think their time frames are way too aggressive, and there should be some alternative to electric cars that is easier and quicker to roll out... at least until the infrastructure has time to catch up.
It would be easy for the governments (at least in the US) to push e-85 again. That should have been required on new cars, and new gas stations when it first came out. It seems like that whole thing stagnated years ago. The synthetic fuels seem like the next new variant of that... that can pump and burn the same. If cars were running a clean burning synth fuel (or maybe hydrogen), they'd be better than electric cars right now too... since not all power plants are exactly clean burning.
If you're in California, I'd suggest you get some solar panels, if you don't already have them
