1/9/2008 1 Bio-fuels and their impact on Agricultural Production Lecture 9 February 11 Geography 1000 Spring 2008 A summary, including controversies, so you can discuss this important debate with less baloney and more substance! Lecture Goals • Discuss current conditions in the US including legislation and production. • Introduce need for biomass-based fuels, including bio-fuels (ethanol) and bio-diesel. (see page 370-371 in text for quick summary) • Discuss how the fuels are made, where they are made, and the role of new technologies applied to new crops. Terms from the Lecture—and for life! • E85—internal combustion engine fuel with only 15% gasoline/ 85% ethanol. E10 will run in almost all currently manufactured cars. • Bio-diesel versus Ethanol: • Sugar platform (conversion of carbs to alcohol— ethanol) versus thermochemical platform (bioprocess cellulose and hemicellulose and even lignin) for biodiesel and some ethanol.

1/9/2008 4 Comparative Results Between Ethanol and Gasoline Are More Relevant to Policy Debate http://strathkirn.com/Presentations/ACSpresSTL07.pdf BUT……. . There are problems Pimentel and Patzek conclude that the energy outputs from ethanol produced using corn, switchgrass and wood biomass are less than the fossil energy inputs and that the same is true for producing biodiesel using soybeans and sunflower. They conclude that ethanol production using corn grain required 29 percent more fossil energy than the ethanol fuel produced,that ethanol production using wood biomass required 57 percent more fossil energy than the ethanol fuel produced and that biodiesel production using soybeans required 27 percent more fossil energy than the biodiesel fuel produced. We are JUST beginning to critically analyze the potential benefits of ethanol production on a significant scale! Critics say it’s not worth it, and is all about the subsidies and the “special interests”of large AG-conglomerates

1/9/2008 5 This report estimates the net energy balance of corn ethanol utilizing the latest survey of U.S. corn producers and the 2001 U.S. survey of ethanol plants. The results indicate that corn ethanol has a positive energy balance, even before subtracting the energy allocated to by-products. The
