The thing about EVs is that to make them you need Lithium, and producing Lithium pollutes more than a life-cycle of an average diesel car.
Sure, they don't pollute on the road, once they're made.
But how do you make the Lithium?
drill a hole (electric drill not diesel)
water pumped in then pressures brings out a 'brine'(alkali Salt) solution
reverse osmosis or just left to evaporate the water in a settling pond for a while
skimming/scraping the lithium layer
EV trucks(in the future) or electric pumps and pipes transport the condensed brine(skimmed/scraped layer).
electric powered factories run by renewables then do chemical separation
oh. they actually put carbon into the mix. meaning they are not evaporating carbon out but putting carbon into lithium. so good place to store carbon
...
dont worry they dont use millions of gallons of diesel in digger trucks. ..its a drill and a pump method
