Research and outreach website. This project was directed by Gregmar I. Galinato, with co-directors Suzette P. Galinato, C. Richard Shumway, and Jonathan K. Yoder. In an era of increased concern about the influence of carbon on the environment, the U.S. government has intervened, requiring the use of biofuels in an attempt to reduce dependence on fossil fuels. This project focuses on one of those biofuels, cellulosic ethanol, and the countervailing forces influencing its development, especially in the Pacific Northwest.
