Definitely it varies by location. The US national average price for fuel right now is 2.90, and the average cost per kWh for electricity is 0.12. Makes the running cost for the ICE vs EV even closer than my original numbers.
I kinda leave the European prices out of the discussion because what they pay tends to be extremely distorted by local taxes.
Based on a quick bit of TCO research, best I can tell is that without subsidies, EVs tend to have a TCO significantly higher than an efficient ICE vehicle. The market is young, obviously, and lots of EVs are aimed at people willing to pay a premium. A Model S, for example, has a TCO over five years of nearly 70 grand (!!). But, a Chevy Spark EV has a TCO of more like 20 grand, which is really showing how cheap they were due to GM dumping them at a loss and the big tax credit. A Prius is around 30K or so, for comparison.
I want an electric, and will get one as soon as there is something in the right price range with the characteristics I'm interested in (sporty, decent looking, sufficient range, reliable, good ergonomics). The Model 3 isn't too bad but it's more than I want to spend on a first-run car, and I won't buy any car with a single touchscreen as the sole interface.
