  1. International Agriculture and Food Workshop University of Wisconsin Law SchoolApril 21, 2009 Dr. John M. Greenler

  2. Cellulosic (Second Generation) Biofuels: Sustainability and Food Security

  3. The Biofuels Ideal

  4. Biomass: currently 10% of global energy flow

  5. World Biomass Energy Flows United Nations IPCC 4th Assessment Report ( 2007)

  6. C. Cleveland and R. Kaufmann, Fundamental principles of energy, 2008, Encyclopedia of Earth

  7. Bureau of Transportation Statistics, “Figure 14-1: U.S. Energy Consumption by Sector, 1994–2004” (2005); http://www.bts.gov/publications/transportation_statistics_annual_report/2005/html/chapter_02/figure_14_01.html

  8. Creating Cellulosic Biofuels • What is Cellulose? • Tough to Breakdown: • Cellulose is the most abundant biological material on Earth

  9. How Cellulosic Ethanol is Made

  10. Plant Breeding for Greater Biofuels Potential

  11. Bioprospecting - Thermophiles at Yellowstone

  12. Improved Biomass Conversion Long-Term Strategy for Improved Fuel/Ethanol Yields 1) Aerobic growth: optimize production of extracellularenzymes (lignocellulases) 2) Anaerobic growth: optimize production of enzymes, transporters, & pathways to funnel carbon to fuel production (ethanol, others)

  13. Developing Improved Enzymes for Biomass Processing “Breaking the Biological Barriers to Cellulosic Ethanol: A Joint Research Agenda”, DOE

  14. High Input, Low Diversity (annuals) Low Input, High Diversity (perennials) Sustainable Bioenergy Practices Sustainability: Economic, Environmental and Social Goal: Predict Behavior of Bioenergy Production Systems Continuous Corn Corn-Soybean-Canola Monoculture switchgrass Switchgrass - Legumes Poplars Early successional Native prairie

  15. Are There Win-Win Scenarios? Ecosystem services: Food, pharmaceuticals, energy, climate regulation, pollination, nutrient cycling, recreation…

  16. Where Should Biofuels Crops Be Grown? - Global Perspectives

  17. GLBRC is one of three Bioenergy Research Centers funded by the Department of Energy to conduct transformational biofuels research DOE Bioenergy Research Centers (BRCs)
