In 2020, total U.S. energy consumption fell to 93 quadrillion British thermal units (quads), down 7% from 2019, according to EIA’s Monthly Energy Review. Last year marked the largest annual decrease in U.S. energy consumption in both percentage and absolute terms in our consumption data series that dates back to 1949. Much of the 2020 decrease in energy use is attributable to economic responses to the COVID-19 pandemic that began in the United States during the spring of 2020.
