Ethanol isn't cure-all

Tuesday, July 11, 2006

Several newspapers carry a story by AP writer H. Josef Hebert on a report to be released soon in the Proceedings of the National Academy of Science:

Ethanol is far from a cure-all for the nation's energy problems. It's not as environmentally friendly as some supporters claim and would supply only 12 percent of U.S. motoring fuel - even if every acre of corn were used.

A number of researchers, the latest in a report Monday, are warning about exaggerated expectations that ethanol could dramatically change America's dependence on foreign oil by shifting motorists away from gasoline.

As far as alternative fuels are concerned, biodiesel from soybeans is the better choice compared with corn-produced ethanol, University of Minnesota researchers concluded in an analysis Monday.

But "neither can replace much petroleum without impacting food supplies," the researchers concluded in the paper published in the Proceedings of the National Academy of Sciences.
