The grass stretched as far as the eye could see, and hundreds more miles beyond that. An ocean of grass—deep enough Test plots of switchgrass at Auburn University have produced up to 15 tons of dry biomass per acre, and five- year yields average 11.5 tons—enough to make 1,150 gallons of ethanol per acre each year.

David Bransby, professor of energy crops at Auburn University, is an expert on switch grass, which President Bush mentioned in his State of the Union address. Bransby says switch grass is cheap to grow and provides a high yield crop that can make a lot of ethanol for a low cost. BLOCK: Switch grass. We figured we...

Creating Cellulosic Ethanol: Spinning Straw into Fuel The perennial grass has a deep root system, anchoring soils to prevent erosion and helping to build soil fertility. "As a native species, switchgrass is better adapted to our climate and soils," adds Nathanael Criers, NRDC Senior Policy Analyst.

Pimentel and Tad W. Patzek, professor of civil and environmental engineering at Berkeley, conducted a detailed analysis of the energy input-yield ratios of producing ethanol from corn, switch grass and wood biomass as well as for producing biodiesel from soybean and sunflower plants.

Switchgrass grown for biofuel production produced 540 percent more energy than needed to grow, harvest and process it into cellulosic ethanol, according to estimates from a large on-farm study. In contrast, corn grain ethanol biorefineries need to use natural gas or other sources of energy for the conversion process.

Much more energy efficient and environmentally friendly than corn ethanol, switchgrass ethanol may be a viable gasoline alternative, a new study says. Ethanol made from a prairie grass shows promise as a viable fuel that could be much more environmentally friendly and energy-efficient than corn ethanol, a new study says.

A new pilot plant that broke ground in Tennessee last week will be testing the use of switchgrass as a feedstock for cellulosic ethanol. Genera Energy is a partnership between the University of Tennessee and DuPont Danisco Cellulosic Ethanol LLC, a joint venture formed this year by DuPont and Genencor to...
