In 2020, energy production in the United States fell to just below 96 quadrillion British thermal units (quads), down more than 5% from 2019’s record high, according to our Monthly Energy Review. In absolute terms, the drop from 101.3 quads in 2019 to 95.8 quads in 2020 marked the largest annual decrease in U.S. energy production on record. Economic responses to the COVID-19 pandemic that began during the spring of 2020 drove most of this decrease.
