In California, “sun-to-wheels” conversion processes that derive electricity or ethanol from corn or switchgrass did not perform as well as photovoltaic electricity for BEVs in a UC Santa Barbara and the Norweigan University of Science and Technology study. The study suggested that even the most land-use efficient biomass-based pathway requires 29 times more land than the PV-based alternative, and that PV PEV systems have the lowest life cycle GHG emissions in the US.
