There's one big comparative that many miss out when comparing the running costs of an EV to an ICE vehicle, and that's the initial difference in cost to buy the EV. It must be a like for like car as well because you will find the EV costs about a third more than it's ICE equivalent. So if you divide this extra cost by mileage saving an EV gives you, you only start saving after 170,000/200,000 miles.
I can buy a diesel van and the exact same one in electric, but the electric is some £34,000 more. If I divide that by what I can save charging the electric version than buying diesel, it's some 200,000 miles before I break even.
So if someone says it's cheaper to charge an EV and their maintenance costs are lower, then yes, I agree. But overall, if I don't do over 170,000/200,000 miles, the EV is more expensive. And all I hear is, "Yeah, but EV prices will tumble". Actually, they've been increasing.
And in the van example, the electric version can't tow!!
AN EV will reduce your ICE carbon footprint by 17% to 30%, and it will also reduce the weight of your wallet because you have to pay the more expensive EV price at the start, or put it on a loan and pay interest on top of the extra cost.
