The Biden administration on Wednesday increased the amount of biofuels that must be blended into the nation’s fuel supplies over the next three years, but held production totals steady for corn-based ethanol, disappointing the biofuel industry and farm advocates. Regan said the final rule would reduce U.S. reliance on oil and support continued growth of biofuels that help combat global warming. (AP Photo/Nathan Howard, File)
