Over the years, the MIT Energy Club has amassed a nice set of biofuels resources. I thought I'd bring them out from the darkness and put links all in one place....
MIT Energy Club Discussion: "Biodiesel: The Other Biofuel" (excellent slides on biodiesel from Kristian Bodek!)
MIT Energy Conference 2007: "Emerging Biofuels: Which Pathways will Enable Scale?"
MIT Energy Conference 2006: "Biofuels Futures: What Role will Biofuels Play in the U.S. by 2020 and How will We Get There?"
