$2.50 for a full charge is roughly 0.16/kwh, so if that were your normal charging, it would make a dent in the savings. BUT, it's still like getting $1.25/gallon gasoline. You can go 60-70 miles for your $2.50, whereas a similar ICE vehicle might only go 1/4 that distance for $2.50 worth of gasoline (depending on the price of gasoline, of course).
Using sandage's calculations for the past 4 years, it means instead of spending $1610 on electricity (at 0.07/kwh), if the price goes to 0.16/kwh then they spend $3680 on electricity for the 4 years. That's still a savings of over $8500 for the four years - and that's using the most expensive electricity available! Some time of use (TOU) pricing can get down to 2 or 3 cents per kwh, but even with an average 11 cents the savings is close to 10k.
However, I've just noticed a chink in the armor of sandage's calculations: it assumes daily driving of roughly 63 miles! (92,000 miles / 365x4). That's technically possible, but doubt we can really rack up 23k miles of driving a year in the i. We're also ignoring battery pack degradation that will reduce range and accured costs for a new pack that must be paid in the 8-10 year timeframe. So, although the running costs are better in an EV, the fixed costs make the relative costs of an EV to an ICE closer to parity. Still, I find the driving experience so much nicer and the benefit to be driving more sustainably well worth it.
