The article explores how lower energy prices could impact biofuels production and agricultural markets. Using a global trade model, researchers found that a significant drop in petroleum prices would lead to a decrease in biofuel use and prices. To make ethanol competitive with gasoline, the cost of production in the U.S. would need to decrease by about 21 percent. This shows that energy prices play a crucial role in the biofuels industry and its competitiveness with traditional fuels.
