Ethanol Isn't Worth the Effort, Study Says

Posted on: Monday, 18 July 2005, 15:00 CDT

ALBANY, N.Y. - Farmers, businesses and state officials are investing millions of dollars in ethanol and biofuel plants as renewable energy sources, but a new study says the alternative fuels burn more energy than they produce.

Supporters of ethanol and other biofuels contend they burn cleaner than fossil fuels, reduce U.S. dependence on oil and give farmers another market to sell their produce.

But researchers at Cornell University and the University of California at Berkeley say it takes 29 percent more fossil energy to turn corn into ethanol than the amount of fuel the process produces. For switch grass, a warm weather perennial grass found in the Great Plains and eastern North America, it takes 45 percent more energy and for wood, 57 percent.

It takes 27 percent more energy to turn soybeans into biodiesel fuel and more than double the energy produced is needed to do the same to sunflower plants, the study found.

"Ethanol production in the United States does not benefit the nation's energy security, its agriculture, the economy or the environment," said the study by Cornell's David Pimentel and Berkeley's Tad Patzek. They conclude the country would be better off investing in solar, wind and hydrogen energy.
