Take 15K miles/year at 4 miles/kWh or 30 miles/gal. 3750kWh or 500 gallons of gas.
At MA electric rates, the electricity is $750, the gas is about $1500. It's unlikely that an electric car consumer would pay more than the $750 delta for the electric charging spot, and would likely be willing to pay only a smaller figure because they are unlikely to do all of their charging in that space or network of spaces.
That premium/willingness-to-pay won't even cover the all-in cost of installing a single EVSE in the first year.
Barring significant over-subscription, that's still a ~10 year payback. With massive over-subscription, it doesn't become a reliable charging source. (My prior post, which I'll leave unedited, was unclear/insufficient in stating it was longer than a one-year payback.)
Consumer/taxpayer demand for a solution, like most problems in a capitalist democracy.
I imagine streets where every nth parking spot has something that looks like a beefy parking meter, but will allow thick-ish extension cords to run from a car to it. Turn it on with an RFID tied to which house you belong to on the street (ensures only locals can use it, charges the electrical costs to the right house).
It's technically doable with the technology in our hands today and not very complicated to install. Give in 10 more years, there'll be even smarter ideas.
