SUPPORTERS SAY BIOFUELS STILL PRIORITY
Producers, farmers not sold on switch from liquid-fueled vehicles
The president and auto industry maintain the nation is on the cusp of a gigantic shift to electric vehicles and away from liquid-fueled cars, but biofuels producers and some of their supporters in Congress aren’t buying it. They argue that now is the time to increase sales of ethanol and biodiesel, not abandon them.
To help address climate change, President Joe Biden has proposed an infrastructure plan that includes billions of dollars to pay for 500,000 electric vehicle charging stations, electrify public vehicles and enhance the nation’s power grid. These moves follow initiatives in California and other states to mandate electric vehicle sales and a goal by General Motors to shift production fully to electric vehicles by 2035.
Yet any shift from liquid-fueled cars to electric would be gradual, given the fleet of 279 million petroleum-powered vehicles now on U.S. roads. And producers of corn-based ethanol and soybased biodiesel argue that biofuels will be needed for the foreseeable future.
The government’s promotion of electric vehicles comes as the U.S. works to reduce carbon emissions that worsen climate change and to compete in the increasingly electric global auto market. The transportation sector accounts for the largest share of U.S. greenhouse gas emissions, and more than 80 percent of that comes from cars, pickups and larger trucks, according to the Environmental Protection Agency.
LMC Automotive, a consulting firm, predicts more than 1 million electric vehicles will be sold in the U.S. in 2023, rising to over 4 million by 2030 — still less than one-quarter of normal annual new vehicle sales of around 17 million. Electric vehicles now comprise less than 2 percent of U.S. new-vehicle sales.
Citing a recent study from Harvard and Tuft universities that found ethanol emits 46 percent less carbon than gasoline, biofuels advocates say it’s imperative for the climate that the nation prioritize increased biofuel production.
Geoff Cooper, who heads the St. Louis-based Renewable Fuels Association, calls ethanol the “low-hanging fruit” for reducing carbon emissions and slowing global warming. He supports an immediate move from gasoline blended with 10 percent ethanol to a blend of 15 percent.
Each year, U.S. refineries produce about 15 billion gallons of ethanol — about 10 percent the volume of gasoline — and 1.5 billion gallons of biodiesel, which is typically blended with petroleum-based diesel for trucks and other heavy vehicles.
Plants around the country produce the fuel, but most are in the Midwest, led by Iowa with 43 ethanol refineries and 11 biodiesel plants. Nearly 40 percent of the U.S. corn crop is used for ethanol, and 30 percent of soybeans goes to biodiesel.
Despite assurances the move to electric will be gradual, many farmers see the shift as a threat to their livelihoods and doubt state and federal officials from urban areas will protect rural economies.
Over time, a switch to electric vehicles likely will force farmers to adapt, said Chad Hart, an agriculture economist at Iowa State University. Farmers in states such as Iowa and Illinois still will mainly grow corn and soybeans because the soil and climate are perfect, but farmers elsewhere will raise other crops, he said.
“Agriculture is always shifting the crop mix to fit whatever markets offer the best opportunity,” he said.
