 Patzek, T.W., "The Midwest's favorite subsidy," The Chicago Tribune (Editorial), Feb 3, 2004.
Press article based on interview.
... That conclusion was reached independently last year by Cornell University agricultural scientist David Pimentel and University of California geoengineering professor Tad W. Patzek ... Pimentel called ethanol "subsidized food burning." Patzek has slammed the ethanol subsidy as one of the most misguided public policy decisions in recent history. "We are burning the same amount of fuel twice to drive a car once," Patzek wrote...
