    FOTW #1151: Lithium-Ion Battery Capacity for New All-Electric Vehicles Sold in the United States Reached a Record High in 2019

    With a 1% increase in sales and increasing battery pack size, all-electric vehicles (EVs) captured a record amount of total plug-in vehicle battery capacity sold in 2019, 17.4 gigawatt-hours. Plug-in hybrid electric vehicles (PHEVs) accounted for a smaller portion of total plug-in vehicle battery capacity due to their lower sales volumes and because they require smaller battery packs than EVs, since they have gasoline-powered engines to extend total vehicle range. PHEV sales decreased 32% from 2018 to 2019, about the same as the decrease in PHEV battery capacity. Calendar year 2018 was the first full year of Tesla Model 3 sales, which accounted for the large increase in total battery capacity between 2017 and 2018.

    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.
