U.S. fuel ethanol production fell dramatically during late March and in April 2020, driven by significant reductions in motor gasoline demand as a result of mitigation efforts for the 2019 novel coronavirus disease (COVID-19). Fuel ethanol production fell to 537,000 barrels per day (b/d) in the week ending April 24, which was the lowest level on record since June 2010, when the U.S. Energy Information Administration (EIA) began collecting weekly fuel ethanol production data. Because almost all finished motor gasoline sold in the United States is blended with 10% ethanol (E10), the drop in gasoline demand has driven similar decreases in fuel ethanol demand and, correspondingly, fuel ethanol production.
