"In the US today, about 95 percent of our ethanol is derived from corn kernels. Because corn is such an energy-intensive plant to grow, and because the methods to process corn into ethanol are also energy intensive, it takes seven barrels of oil to produce eight barrels of corn ethanol, from field to processing plant, according to research by the traditionally right-leaning Cato Institute. So when you factor in production, ethanol curbs climate-changing vehicle emissions by a mere 12 percent over gasoline, according to a 2006 University of Minnesota study by Jason Hill and David Tilman. (With blends like E85—85 percent ethanol, 15 percent gas—that emissions reduction plummets to 2 percent.) And that’s only if the corn is grown on existing fields. Converting wildlife preserves to cropland to grow more ethanol would result in a net greenhouse gas release that would exacerbate global warming and negate any benefit, Hill told the University of Minnesota’s alumni magazine.
"An earlier study published in BioScience in 2005 concurs with Hill and Tilman’s findings. The researchers looked at the carbon dioxide (CO2) emissions, cropland area requirements, and other environmental consequences of growing corn and sugarcane to produce fuel ethanol, and found that “the environmental impacts far exceed any value in developing this energy resource on a large scale.”
