The number of electric vehicle miles traveled (eVMT) has been increasing each year since the introduction of the first mass market plug-in vehicles in late 2010. Beginning in 2014, annual all-electric vehicle eVMT has exceeded that of plug-in hybrid electric vehicles in the US, reaching a new high of nearly 10 billion miles in 2020.
Between 2015 and 2020, the eVMT of all plug-in electric vehicles more than quadrupled.

More than 1.7 million PEVs have been sold, driving 52 billion miles on electricity since 2010, thereby reducing national gasoline consumption by 0.42% in 2020 and 1.9 billion gallons cumulatively through 2020.
In 2020, PEVs used 4.4 terawatt-hours of electricity to drive 13.7 billion miles, offsetting 500 million gallons of gasoline. Since 2010, 68% of PEVs sold in the United States have been assembled domestically, and 77 gigawatt-hours of lithium-ion batteries have been installed in vehicles to date.
