If we ignore the cost of gas, it'll also change the math...
Needless to say, need to include all costs for a fair comparison. A few years ago when my wife had a Fiat 500e and I was commuting on a 1988 Honda CRX (~40 mpg). The energy cost was higher for the Fiat than the Honda at the time. (Electricity is very expensive in CA). Gas has gone up lately (but then, so has PG&E), I haven't run the numbers in recent years. Might be a wash now.
Gas an electricity prices vary widely so do the math for your area, but don't ignore any costs.
PGE EV-A rate plan has been $0.13/kWh. Fiat 500e gets about 4 mi/kWh, so about $0.0325 per mile. Assuming gas price over that period averaged $2.50, then at 40mpg gas cost $0.0625 per mile. Which looks like twice as much, not nearly the same.
I’m also in CA, and I ran the numbers on my plug-in C-MAX. It is roughly a wash (and the gas mileage is pretty unimpressive, at 35 MPG). It’s convenient to never have to go to the gas station (we average 110 MPG overall), but it’s sad that there’s no savings/incentive to actually be on electric with this vehicle).
It could be different for other vehicles that are more efficient (don’t have ICE components to lug around), or for people with their own solar charging.
