Generally for EVs it matters where the electricity comes from. (From memory), coal fired electricity has a EV break even at 110k miles, hydro power break even is down at 20k. (I'm on a phone, but can try to dig out the article that looked at this exact question - it also mentioned that a lot of places where we get rare minerals for the batteries are run by warlords which use child labor.. so it is not all roses)
