Switchgrass grown for biofuel production produced five times more energy than needed to grow, harvest and process it into cellulosic ethanol, finds a large farm study by researchers at the University of Nebraska-Lincoln published Monday.
The five year study also found greenhouse gas emissions from cellulosic ethanol made from switchgrass were 94 percent lower than estimated greenhouse gas emissions from gasoline production.
"This clearly demonstrates that switchgrass is not only energy efficient, but can be used in a renewable biofuel economy to reduce reliance of fossil fuels, reduce greenhouse gas emissions and enhance rural economies," said principal researcher Ken Vogel, a U.S. Department of Agriculture-Agricultural Research Service geneticist in the university's agronomy and horticulture department.
