Just imagine:
ALL the money that flew into "Fossil & Co" throughout the last, lets say, 50 or 60 years, including all implicit fundings, like state-building-streets or universities-masters-engineering-focus-ICE, all the money for lobbying, all the money for all the (counter)campaigns (from ALL sides), and all that money....
...WHAT IF we would have spent all of this money instead on Battery Research and all this Renewable Energy stuff?
Where would we be today on techdev curve? ;-) ;-)
We would probably be dramatically farther behind in the Materials Research conducted by the chemical companies underlying the fossil fuels industry, which has itself been necessary to the improvements in battery & semiconductor technologies we are now enjoying. Polyimides don’t invent themselves!
“What If?” history is fun, but there are always Tradeoffs.
We would have inefficient and polluting engines, leaded gasoline, steam engines burning coal, no high performance plastics, and probably more even wars around oil and gas and slower economy leading to less resource to fund battery research...
I mean, batteries and solar panels are cool, but thinking about the future doesn't mean we should forget the present. The advance we could have gotten by diverting funding away from fossil fuels and towards renewables and batteries is to balance with the damage caused by using outdated fossil fuel technology before the transition.
Cities are breathable now thanks to all the progresses modern engines have made. They will be even more breathable with zero emission cars, but I prefer to wait a bit more in these conditions than waiting a bit less in a smog filled city.
I'd love to see a 'manhattan project' to get off of oil, in any way possible eg batteries or algae-produced diesel, whatever works, for geopolitical purposes.
We might have shaven off ~10 years from the current timeline.
Batteries are only a part of the equation. Practical EVs were enabled not just by Li-ion batteries but by IGBTs. And semiconductor development moved about as fast as possible.
And then there's a gulf between lead-acid batteries and Li-ions. I think only NiMH batteries would have been a reasonable midpoint, and even they would have been impractical for full EVs.
Exactly the same as today.
Ungodly amount of money was spent on battery research since 1945, at least $100-150B since 2000 alone. Every combination of anode, cathode and electrolyte was tried, tested and evaluated. We got silver-zinc, Ni-Cd, NiMH and finally Li-Ion batteries as the result.
