It should come as no surprise that California has more electric/hybrid vehicles, as a percentage of all vehicles on the road statewide, than any other state.
The state — which has the highest average gas price among the states — offers rebates and other credits for owners of hybrid or electric vehicles.
The California Vehicle Rebate Program will pay up to $7,000 for qualified purchasers or leasers of electric and hybrid vehicles; that amount varies based on household income, however.
In this graphic, the data for which came from Insurify, it’s notable that higher gas prices in a given state don’t always translate directly to a higher proportion of electric or hybrid cars.
