So a little fuel on the fire / convolution here: Cost of ownership is highly dependent upon cost of fuel.

Gas prices are historically relatively volatile. I don't believe that we can really safely make any assumptions about stability over a 10 year period. Electricity pricing by contrast is tightly regulated with minimal fluctuations. Moreover, the cost of electricity is also source dependent, whether people choose to subsidize green power grid alternatives or employ solar panels on their homes, there can still be substantial if stable variance between consumers, but it tends to be relatively constant for any given area.

For me, I will be an additional $1200 ahead at the end of 10 years if my PV array is entered into the equation after accounting for out of pocket expense for the array and net production over that same period.

Obviously it's not so simple as that for countless drivers, lacking solar arrays of their own or options to reduce their energy costs, but that brings me to another huge point for many EV owners: Never having to stop for gas. (My i3 is actually a range extended hybrid, but using gasoline is 100% optional.)

Because I very rarely travel outside my EV range, not only can I be assured of having full range every time I leave the house with charging at home, I never have to go out of my way or wait in line for fuel or spend time waiting for an attendant (yippee for anti-self serve law in Oregon).
