Current production of ethanol is about 3.4 billion gallons per year, but that total could reach 80 billion gallons or more under the scenario outlined in this report. Such an increase in ethanol production would see transportation fuels from biomass increase from 0.5 percent of U.S. consumption in 2001 to 4 percent in 2010, 10 percent in 2020 and 20 percent in 2030. In fact, depending on several factors, biomass could supply 15 percent of the nation's energy by 2030.
Meanwhile, biomass consumption in the industrial sector would increase at an annual rate of 2 percent through 2030, while biomass consumption by electric utilities would double every 10 years through 2030. During the same time, production of chemicals and materials from bio-based products would increase from about 12.5 billion pounds, or 5 percent of the current production of target U.S. chemical commodities in 2001, to 12 percent in 2010, 18 percent in 2020 and 25 percent in 2030.
Nearly half of the 2,263 million acres that comprise the land base of the U.S. has potential for growing biomass. About 33 percent of the land area is classified as forest, 26 percent as grassland, 20 percent as cropland, 13 percent as urban areas, swamps and deserts, and 8 percent as special uses such as public facilities.
The report, titled "Biomass as Feedstock for a Bioenergy and Bioproducts Industry: The Technical Feasibility of a Billion-Ton Annual Supply," was sponsored by DOE's Office of Energy Efficiency and Renwable Energy, Office of Biomass Program. Lynn Wright and Anthony Turhollow of ORNL, Bryce Stokes of the USDA Forest Service and Don Erbach of the USDA Agriculture Research Service are co-authors of the report.
