U.S. regular retail gasoline prices averaged $2.17 per gallon (gal) in 2020, 44 cents/gal (17%) lower than in 2019 and the lowest annual average since 2016. Gasoline prices at the beginning of the year were more than $2.50/gal; however, responses to the COVID-19 pandemic resulted in widespread reductions in passenger travel and gasoline demand, contributing to lower gasoline prices across the United States.
