According to estimations referred to by the U.S. DOE’s Office of Energy Efficiency & Renewable Energy, in 2018 plug-in electric cars in the U.S. displaced 323 million gallons of gasoline (950 million gallons cumulatively).

The number was calculated assuming 8.6 billion miles driven on electricity by plug-ins (over 25 billion miles cumulatively), which used some 2.8 TWh of electricity.

The displacement of 323 million gallons of gasoline is equivalent to 0.23% of total gasoline usage in the country last year, and it increased by 42% year-over-year.

Assuming that plug-in sales will continue to grow, we hope for 1% gasoline displacement at the end of 2020.

U.S. plug-in vehicles, which include all-electric (EV) and plug-in hybrid electric vehicles (PHEV), have been saving increasing amounts of gasoline. In 2018, plug-in vehicles on the road displaced 323 million gallons of gasoline or about one quarter of a percent of all gasoline used in the United States. Gasoline displacement from plug-in vehicles is about 42% more than it was in 2017 and about twice as much as it was in 2016. The gasoline displacement from EV versus PHEV was split almost evenly in 2012 and 2013 but EV accounted for two-thirds of the gasoline displacement by 2018.

Note: Includes only light-duty vehicles.
