The future of biofuels is not in corn
...tes show that corn ethanol could reduce greenhouse gas
emissions by 18 percent to 28 percent, while cellulosic ethanol is estimated to offer a reduction of 87 percent compared to gasoline. Ethanol is not the solution to revitalizing rural America. While higher commodity prices and cooperatively owned...
