In December 2007, the Congress expanded the renewable fuel standard (RFS), which requires rising use of ethanol and other biofuels, from 9 billion gallons in 2008 to 36 billion gallons in 2022.  To meet the RFS, the Departments of Agriculture (USDA) and Energy (DOE) are developing advanced biofuels that use cellulosic feedstocks, such as corn stover and switchgrass. The Environmental Protection Agency (EPA)
administers the RFS.

This report examines, among other things, (1) the effects of increased biofuels production on U.S. agriculture, environment, and greenhouse gas emissions; (2) federal support for domestic biofuels production; and (3) key challenges in meeting the RFS. GAO extensively reviewed scientific studies, interviewed experts and agency officials, and visited five DOE and USDA laboratories.

The Energy Independence and Security Act of 2007 (EISA) establishes new renewable fuel categories and eligibility requirements.  EISA sets the first U.S. mandatory lifecycle GHG reduction thresholds for renewable fuel categories, as compared to those of average petroleum fuels used in 2005.  The regulatory purpose of the lifecycle greenhouse gas emissions analysis is to determine whether renewable fuels meet the GHG thresholds for the different categories of renewable fuel.

This report is the result of a thorough review process, based on research of recent publications (mainly until the end of 2008, but considering also eminent articles published before June 2009), and the involvement of many experts worldwide. In particular, the report benefitted substantially from the exchange with the Rapid Assessment workshop held by the International SCOPE biofuels project in Germany, September 2008, and the subsequent publication of the proceedings, which had involved about 75 scientists from all continents and reflected a broad range of different views concerning the analysis and assessment of biofuels.

This study follows a project that defined the scope and cost of a technology research and development program that demonstrated the feasibility of using an off the shelf, unmodified, large-bore diesel powered generator in a grid-connected application, utilizing various blends of BioDiesel as fuel.  The other primary goal of the project was to substantially reduce the Nitrous Oxide emissions from the burning of this fuel.

This White Paper provides a detailed  comparison of operating costs for buses used in a transit system arc investigated considering four alternative fuels: biodiesel, compressed natural gas, methanol, and diesel.  The study considers both tangible costs such as fuel, maintenance, and infrastructure, and intangible costs associated with different levels of bus engine operating
reliability under alternative fuels.
