Average US price for electricity is ~$.15/kwh. A Model 3 will use ~330 wh/mile at highway speeds, and if you charged _very_ inefficiently (level 1), you'd see gross of around 360 wh/mile.

Compared to a gas car that can get 40 mpg on the highway this works out to: 40 mpg == 1 gallon == ~$2.85 (current price here) == 0.07125/mile EV == .360 * .15 == .054/mile

Of course, if you have time of use rates, you might pay half that for the EV. If you drive in town, your efficiency might be more like 270wh/mile too.

Similarly, that MPG is... very arbitrary. But the bottom line is that most people are getting a significantly lower $/mile purely on energy usage.

Gasoline is very expensive. If it wasn't so expensive, we'd burn it to make electricity.



We do, it's called an alternator.


Well, yeah, and people use gas generators in remote places occasionally. But I meant at utility scale. :)
