True Cost of Ownership

[ikjadoon]

I know not everyone's a math wiz, but (0.333 x 12) does not equal 3. (HINT: it's 4.) (0.333 kWh/mi x $0.12/kWh = 4 cents per mile)

Main point:
With today's low gasoline prices, if you pay average or higher-than-average electricity prices, there's not a big difference in fuel cost between an EV and an efficient ICE vehicle.

For example, at $2/gallon and $0.12/kWh, a 50 mpg Gen 3 Prius has exact the same fuel costs as a 333 Wh/mi EV.
And at $0.15kWh, a Model S's fuel costs are comparable to a whole slew of 40mpg mid-size hybrid sedans.
(I know the Tesla is bigger and better. Just sayin'.)

Oh, shucks, I've no idea where the 3 came from (or do I? Maybe the number is my subconscious now). I was just playing around with the range calculator, tbh. Thanks for the correction, mate.

Right you are, but there is still a lot of range in fuel prices that is difficult to generalize. I currently own a Prius Vagon and a LEAF. We drive both cars gently and end up about 50 mpg in the ICE and 5.2 miles/kWh in the EV.

I pay about 4 cents a mile for the ICE, but from next week after my PV is up and running I'll pay about 0.5 cents a mile for the EV. Home PV is not available to everybody, but it can be an option for enough people that it should not be ignored in the discussion.

And frankly ? EV ownership is half-baked. EV+PV is the whole pie.

Also, the cost of electricity doesn't fluctuate like the price of gas does either. You won't end up paying an extra few dollars just because you decided to fill up your car today instead of yesterday.

It was obviously a typo
