The amount of electricity consumed by plug-in electric vehicles (PEV) in the United States has nearly doubled in the last two years – from 1.44 terawatt-hours in 2016 to 2.85 terawatt-hours in 2018. The share of electricity consumption from all-electric vehicles (EV) increased compared to the electricity consumption from plug-in hybrid electric vehicles (PHEV). In 2018, EV accounted for 61% of all PEV electricity consumption while PHEV accounted for the remaining 39%.
Note: Includes only light-duty vehicles.
