Researchers say biofuels could replace 50% of global fuel supply without affecting food, pasture

January 11, 2011 |

In Illinois, researchers at the University of Illinois-Urbana Campaign have determined that half of the world’s current fuel consumption could be replaced with biofuels without competing with food or pastureland. A class of biofuel crops called low-impact high-diversity (LIHD) perennial grasses could produce bioenergy while maintaining grassland. Adding LIHD crops grown on marginal grassland to the marginal cropland estimate from earlier scenarios nearly doubled the estimated land area to 1,107 million hectares globally, even after subtracting possible pasture land – an area that would produce 26 to 56 percent of the world’s current liquid fuel consumption.
