This report focuses on those policies contained in the 2008 farm bill (the Food, Conservation, and Energy Act of 2008; P.L. 110-246) that support agriculture-based renewable energy, especially biofuels. The introductory sections briefly describe how these policies evolved and how they fit into the larger context of U.S. biofuels policy. Then, the policies specific to the 2008 farm bill are defined in terms of their function, goals, administration, funding, and implementation status. Finally, a section reviews the major emerging issues related to U.S. Department of Agriculture (USDA) energy programs, particularly as related to their possible inclusion in the next farm bill.
