dracodraconisBioelectricity better than biofuels for transport : Nature News
A recent study comparing the efficiency of crop-based ethanol versus electricity generated from burning biomass determined that biomass-fired electricity is more efficient when then entire supply chain is taken into account. The study specifically looked at the efficiency of powering automobiles using two metrics: kilometres vehicular travel per hectare and emissions per hectare. They determined that a vehicle powered by biomass-fired electricity would travel 81% farther with half the greenhouse-gas emissions compared to an ethanol-based vehicle.
