US residents consume roughly 10 million barrels per day of gasoline for transportation fuel. Using the ethanol yields projected to be attainable from advanced fermentation technology ( table 10.8 ), how many acres would need to be devoted to cellulosic biomass production to supply 10% of the miles traveled on gasoline using fermentation ethanol as the automotive fuel? Note that ethanol provides roughly 2/3 the miles per gallon attainable from gasoline. Compare your answer with the total area of France and of the state of California.
