How Rhode Island compares
Ranked by yearly saving, Rhode Island is 45th of 51. Savings run from $66 in Hawaii to $1,276 in Louisiana. The saving here is $342 less than the $1,084 a driver saves at the U.S. average price.
Gas would have to fall below $2.60 a gallon, from $4.33 now, before charging an EV in Rhode Island stopped saving money.
Public chargers averaged $0.42/kWh nationally on October 16, 2026, according to AAA. Divided by the 28.29¢/kWh home rate here, that makes public charging 1.5 times the home price, so every mile charged in public cuts the saving. Charging only at home would raise it to $778 a year.
One of its two neighbors saves more: Connecticut at $883.
