I didn't say they have no environmental impact. I said EV's sound great if you don't factor in the environmental cost of their batteries.
And that's not even mentioning the cost of creating more electricity to charge them
On the one hand you won’t get the huge fuel cost savings in Iowa on electric over gas that most other states have because of Iowa’s socialist low gas prices.
On the other hand the electricity in the state is often among the highest % renewable in the US because of Iowa wind energy.
Iowans have close to if not the cleanest fuel for EVs, but they have the cheapest gas which naturally will make Iowa the last state to embrace EVs.
