In 2016, there were six states with more than two plug-in vehicles (PEVs) registered per 1,000 people. California had the highest concentration of PEVs with 6.65 PEVs per 1,000 people. Hawaii had the second highest concentration with nearly four PEVs per 1,000 people followed by Washington and Oregon with about three PEVs per 1,000 people. Vermont and Georgia round out the top six with over two PEVs per 1,000 people. Mississippi had the lowest concentration of PEVs, but all 50 states and the District of Columbia had at least some PEVs. PEV registrations within a state are influenced by many factors, including state and local incentive programs, charging infrastructure, and fuel pricing.
