• Tad W Patzek. Patzek, a professor at UC Berkeley’s Department of Civil and Environmental Engineering. “Thermodynamics of the Corn-Ethanol Biofuel Cycle”. 24 March 2005 – Reviews and corrects the assumptions and calculations of the primary pro- and con- ethanol factions, and concludes that corn ethanol is a net loss to the environment and in energy, and a net contributor of CO2.

• Tad W. Patzek. “Sustainability of the Corn-Ethanol Biofuel Cycle”. U.C. Berkeley. 2004 – “I also show that in 2004 ethanol production will generate 8 million tonnes of CO2 over and above the amount of CO2 generated by burning gasoline with 115% of the ethanol energy content to account for oil recovery, refining, and transport.”
