WASHINGTON – President Joe Biden will announce Tuesday another step to try to reduce prices for drivers who have been paying more to fill up their tanks: expanding the availability of biofuels.

While visiting an ethanol plant in Iowa, Biden will announce the administration plans on allowing gasoline that uses a 15% ethanol blend to be sold during the summer, according to senior administration officials who spoke on condition of anonymity.

Called E15, the blend can cost 10 cents per gallon less on average at the 2,300 gas stations where it’s sold, the officials said.

Regular gas is averaging around $4.11 a gallon compared with $2.86 a year ago, according to AAA, and Biden is under political pressure to show he is doing what he can to ease the price pain at the pump.

Inflation hits new high on oil price spike

His announcement comes the same day the the Labor Department said consumer prices leaped 8.5% since last March, the fastest pace since December 1981. Inflation has now notched new 40-year highs for five straight months.

Gasoline prices, which jumped 18.1% from March 2021 to March 2022, were the main reason for the inflation spike.

Anticipating that big number White House press secretary Jen Psaki on Monday said the administration expected inflation “to be extraordinarily elevated” because of the jump in oil prices after Russia invaded Ukraine. 

“We are taking a range of steps to reduce the price of gas to move us toward a long-term, more clean energy economy,” she also said.

Biden previously announced the U.S. would try to spur oil production and tap strategic reserves to ease gas prices, which spiked after Russia invaded Ukraine, prompting a ban on Russian oil imports.

Biofuels are limited, but EPA can grant waiver

Administration officials said the action Biden will announce Tuesday will increase the use of home-grown biofuels, reducing dependence on foreign fuels.

While almost all gasoline in the U.S. contains 10% ethanol, access to E15 is curtailed annually in some states from June 1 to Sept. 15 because it is believed to contribute to smog during warmer weather.
