SUBSCRIBE to the Fact of the Week

In 2015, there were five states with more than two plug-in vehicles (PEVs) registered per 1,000 people. California had the highest concentration of PEVs with 4.68 PEVs per 1,000 people. Hawaii had the second highest concentration with nearly three PEVs per 1,000 people followed by Washington, Georgia, and Oregon with about two PEVs per 1,000 people. Georgia is the only eastern state with over 2 PEVs per 1,000 people, likely due to generous state incentives that were offered until the summer of 2015. Mississippi had the lowest concentration of PEVs, but all 50 states and the District of Columbia had at least some PEVs.
