Corn is delivered to the Green Plains ethanol plant in Shenandoah, Iowa, on Jan. 6, 2015. Roughly 100 trucks a day filled with corn flow into the ethanol plant in southwest Iowa even as crude oil prices continue to collapse. Oil prices may have dipped below $50 a barrel for the first time since April 2009, but ethanol plants across the nation continue to operate at a brisk pace in order to satisfy a domestic and export demand that hasn’t weakened.
