Ethanol

WASHINGTON — President Biden announced on Tuesday a plan to suspend a ban on summertime sales of higher-ethanol gasoline blends, a move that White House officials said was aimed at reducing gas prices but that energy experts predicted would have only a marginal impact at the pump.The Environmental Protection Agency will issue a waiver that would allow the blend known as E15 — which is made of 15 percent ethanol — to be used between June 1 and Sept. 15. The White House estimated that approximately 2,300 stations in the country offer the blend and cast the decision as a move toward “energy independence.”“E15 is about 10 cents a gallon cheaper,” Mr. Biden said, speaking after taking a tour of a production facility that produces 150 million gallons of bioethanol annually. “And some gas stations offer an even bigger discount than that.”“When you have a choice, you have competition,” Mr. Biden added. “When you have competition, you have better prices.”The decision to lift the summertime ban comes as Mr. Biden faces growing pressure to bring down energy prices, which helped drive the fastest rate of inflation since 1981 in March. A gallon of gas was averaging $4.10 on Tuesday, according to AAA. Last month, the president announced a plan to release one million barrels of oil a day from the U.S. Strategic Petroleum Reserve over the next six months.Understand Inflation in the U.S.Inflation 101: What is inflation, why is it up and whom does it hurt? Our guide explains it all.Your Questions, Answered: Times readers sent us their questions about rising prices. Top experts and economists weighed in.Interest Rates: As it seeks to curb inflation, the Federal Reserve announced that it was raising interest rates for the first time since 2018.How Americans Feel: We asked 2,200 people where they’ve noticed inflation. Many mentioned basic necessities, like food and gas.Supply Chain’s Role: A key factor in rising inflation is the continuing turmoil in the global supply chain. Here’s how the crisis unfolded.Ethanol is made from corn and other crops and has been mixed into some types of gasoline for years as a way to reduce reliance on oil. But the blend’s higher volatility can contribute to smog in warmer weather. For that reason, environmental groups have traditionally objected to lifting the summertime ban, as have oil companies, which fear greater use of ethanol will cut into their sales.How much the presence of ethanol holds down fuel prices has been a subject of debate among economists. Some experts said the decision was likely to reap larger political benefits than financial ones.“This is still very very small compared with the strategic petroleum reserve release,” said David Victor, a climate policy expert at the University of California, San Diego. “This one is much more of a transparently political move.”Lawmakers in corn-producing states have been urging Mr. Biden to use biofuels to fill the gap created by the United States ban on importing Russian oil. Oil refiners are required to blend some ethanol into gasoline under a pair of laws, passed in 2005 and 2007, intended to reduce the use of oil and the creation of greenhouse gases by mandating increased levels of ethanol in the nation’s fuel mix every year. However, since passage of the 2007 law, the mandate has been met with criticism that it has contributed to increased fuel prices and has done little to reduce greenhouse gas pollution.Inflation F.A.Q.Card 1 of 6What is inflation?
