In a recent report assessing multiple properties of plug-ion electric vehicles (PEVs) solid in the US, a team from Argonne National Laboratory (ANL) estimates that the energy savings in the United States due to light-duty PEVs in 2019 was 44.8 trillion Btu, up 47% from 2018.
The reduction of energy use by plug-in electric vehicles translates to a savings of 470 million gallons of gasoline in 2019.

More than 1.4 million PEVs have been sold, driving more than 37 billion miles on electricity since 2010, thereby reducing national gasoline consumption by 0.34% in 2019 and 1.4 billion gallons cumulatively through 2019.
In 2019, PEVs used 4.1 terawatt-hours of electricity to drive 12.7 billion miles, offsetting 470 million gallons of gasoline.
Since 2010, 69% of all PEVs in the US have been assembled in the United States, and more than 60 gigawatt-hours of lithium-ion batteries have been installed in the vehicles to date.
