I was looking for something else and came across this interesting paragraph in a local paper, The Forecaster:
Any volunteers to dig out comparable numbers for the other New England states?According to the Maine Bureau of Motor Vehicles, more than 800 electric and gas hybrids were registered in the state as of Dec. 29, 2014. Of those, 154 are completely electric: 98 Chevy Volts, 42 Nissan Leafs, and 14 Teslas.
