Therefore, bioenergy should maximize land-use efficiency when addressing transportation and climate change goals. Biomass could power either internal combustion or electric vehicles, but the relative land-use efficiency of these two energy pathways is not well quantified. Here, we show 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. These results suggest that alternative bioenergy pathways have large differences in how efficiently they use the available land to achieve transportation and climate goals.

With corn and soy prices hitting record high prices and an ethanol glut flooding the market, ethanol’s profit margin per gallon has dropped to a meager 25 cents from $2. That’s causing numerous ethanol and biodiesel plants to get put on hold or downright canceled. Hundreds of millions of gallons of production capacity and hundreds of millions of dollars in biofuel investments are now hanging in limbo, as investors hope prices will level out.
