All-electric vehicles (EVs) and plug-in hybrid electric vehicles (PHEVs) traveled a combined 19 billion miles on electricity in 2021, according to the data released by the Department of Energy (DOE).
This includes all miles traveled in EVs and the electric portion of miles traveled in PHEVs.
EV miles driven increased by 57% from 2020 to 2021, while electric miles driven in PHEVs increased by 24%. Total electric miles were still less than 1% of the 2.9 trillion vehicle miles driven in 2021, however.
In a related news, in 2021, 73% of all plug-in vehicles on the road were assembled in North America, with 65% of them built in the United States. Japan was a distant second at 12%, followed by Germany at 6%.
Since 2011—the first full year of mass market plug-in vehicle sales in the U.S.— a greater share of plug-in vehicles has been assembled domestically than conventional internal combustion-powered vehicles.
