EIA data shows 10% “blend wall” broken in 2021 thanks to E15 and E85

In Washington, as higher ethanol blends like E15 and E85 continued to expand in the marketplace in 2021, thirty-five states and the District of Columbia blasted through the so-called 10% ethanol “blend wall,” according to data released recently from the U.S. Energy Information Administration. Minnesota and Iowa led the way in 2021, with ethanol accounting for 12.6% and 11.6%, respectively, of statewide gasoline consumption. California, Texas, and 12 other states had an average ethanol blend rate near 10.7%. The national average ethanol blend rate reached a record 10.32% in 2021, according to the data.
