The ag industry, some politicians and now automakers are pushing the idea that ethanol
made from corn will help reduce reliance on foreign oil. But, another study further
indicates that corn ethanol is not the best solution. The GLRC’s Lester Graham reports:


Despite the huge push for corn ethanol, a new study adds to the growing body of
evidence that indicates ethanol from corn is not a viable answer to replace gasoline. New
research from the University of Minnesota has been published by the Proceedings of
the National Academy of Sciences
. It shows that ethanol from corn only yields 25
percent more energy than it takes to produce it.


The study also found greenhouse gas emissions and air pollution improvements were
only slight using corn ethanol, a bit better using soy diesel. But, the researchers say even dedicating all U.S. corn and soybean production to bio-fuels instead of food would only
meet 12 percent of the demand for gasoline and six percent of the demand for diesel.


The researchers conclude that other more woody plants and wood by-products could
provide much greater supplies and environmental benefits than food-based bio-fuels.


For the GLRC, this is Lester Graham.
