President Joe Biden is all in on a new plan to bring down gasoline costs. It turns out that the move is also likely to make the air dirtier.
Biden is planning expanded sales of gasoline with a higher ethanol content than usual during the summer months. Most American fuel stations already carry gasoline mixed with about 10% ethanol, made from corn. But this summer, more drivers will be able to fill their cars up with E15 -- the 15 stands for 15% ethanol.
