    FOTW #1144: U.S. Energy Savings Due to Light-Duty Plug-In Electric Vehicle Use Estimated at 44.8 Trillion Btu in 2019

    Originally posted by the Department of Energy Office of Energy Efficiency and Renewable Energy | Original Article

    Due to their efficiency, plug-in electric vehicles (PEVs) reduce the amount of energy used by light-duty vehicles compared to their internal combustion engine counterparts. Estimates show 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.

    Notes: Gasoline conversion to Btu using gross heating value 125,000 Btu/gallon. Electricity conversion to Btu using 3,412 Btu/kWh.

    FOTW #1138: New Light-Duty Vehicle Fuel Economy in the United States Has Nearly Doubled Since 1975

    Originally posted by the Department of Energy Office of Energy Efficiency and Renewable Energy | Original Article

    From 1975 to 2019, fuel economy for all new light-duty vehicles produced for sale in the United States has increased from an average of 13.1 miles per gallon (mpg) to 25.5 mpg, a 95% increase. This is a significant improvement considering the new vehicle mix has recently shifted heavily towards SUVs and pickups, which generally have lower fuel economy than cars. The car SUV category showed the most improvement from 1975 to 2019 with a 143% increase in fuel economy. Cars, truck SUVs and vans each increased by more than 100% in that same time frame, while pickups increased by 63%.

    Note: Data for 2019 are preliminary. Data are production weighted. The “Car SUV” category includes 2-wheel drive SUV with inertia weight of 4,000 lb. or less.
