Biomass or Biomess? Are Biofuels more costly than they are worth?

There is a new study out that was conducted jointly by UC Berkeley and Cornell that gives lie to the idea that biomass derived fuels and fuel additives are good for the environment. Ethanol, the favorite of Donks and treehuggers everywhere is one of the worst. It requires between 1 1/3 to 1 1/2 TIMES the amount of fossil fuel to make than is produced depending on the biomass source. Biodiesel is even worse requiring between 127% and 218% of the fossil fuel to make. Using waste that would normally be discarded to make these products, like used cooking oil and lawn waste etc., if it can be done with minimal additional fossil energy input is one thing, but growing these crops for the express purpose of making fuel from them is just plain STUPID!
