A gallon of ethanol has a lower energy content than a gallon of gasoline (as measured by BTU content).

In fact, the report envisages nuclear energy's contribution to vehicle fuel services in 10 years» time to be as important as ethanol is today.
And, as with the corn - ethanol debacle unfolding before our eyes, the alternatives to fossil fuel will simply never fill the gap between current and assumed future demand and supply of energy.
And while I'm not personally a fan of ethanol, the plant described at the following link seems to address many of the concerns about ethanol and big - scale farming by treating wastes from one process as feedstock into another and reducing the amount of energy required at each stage.

The National Commission on Energy Policy reported in December that, if fleet mileage in the U.S. rises to 40 mpg — somewhat below the current European Union fleet average for new vehicles of 42 mpg and well below the current Japanese average of 47 mpg - then as switchgrass yields improve modestly to around 10 tons / acre it would take only 30 million acres of land to produce sufficient cellulosic ethanol to fuel half the U.S. passenger fleet.
Because so little energy is required to cultivate crops such as switchgrass for cellulosic ethanol production, and because electricity can be co-produced using the residues of such cellulosic fuel production, reductions in greenhouse gas emissions for celluslosic ethanol when compared to gasoline are greater than 100 per cent.
