Science Magazine reports that converting biomass to ethanol fuel for vehicles powered by internal combustion engines is much less efficient than burning biomass to generate electricity for batteries of electric vehicles. The same acre of switchgrass, for example, could propel an electric powered car 7,000 miles further than a car with a combustion engine. The study concluded that “bioelectricity outperforms ethanol across a range of feedstocks, conversion technologies, and vehicle classes. Bioelectricity produces an average 81% more transportation kilometers and 108% more emissions offsets per unit area cropland than cellulosic ethanol.”
