I mean, in BTTF II/III, the DeLorean was upgraded with a Mr Fusion and made a flying car but it still used an ICE to drive. How weird is that?
Meanwhile, it's no longer a question that solar and wind are going to comprise a large fraction of our energy supply in the near future; it's only a question of how much, how quickly, whether it will cut CO2 emissions enough, and what the waste/lifecycle costs will amount to. Electric cars are the way things are going; even if Tesla collapsed into its own hype-bubble, every other car manufacturer now produces electric cars, people are buying them, the charging infrastructure is getting built out. The only questions left are what (large) fraction of the market electric vehicles will eventually grow to, how quickly they'll reach it, and whether it will again help our CO2 emissions enough, fast enough, and what waste/lifecycle problems will EV introduce.
It's weird to me that between renewables and EV we have a real chance at Y2K'ing global warming.
Electric cars are older than gas cars, and never really went away, though they spent a long time as niche vehicles.
The Chevy EV1 proved electric vehicles "desirable" before Tesla existed.
