Less Corn, Less Land Required to Produce Ethanol

Less corn is required in order to produce ethanol, according to a report by the USDA Office of Energy Policy and New Uses. Ethanol yields have increased 10 percent for the past 20 years, requiring less corn for production. Corn yields also have increased by 39 percent over the past 20 years, requiring less land to produce the biofuel. Based on the report, ethanol has made the transition from an energy sink to a substantial net energy gain. View the report.
