Cal and Cornell: Biofuels are Bunk

Two recent University studies you may never hear of find that biofuels aren't all their cracked up to be:

For ethanol production, the study found that:

* Corn requires 29 percent more fossil energy than the fuel produced.
* Switch grass requires 45 percent more fossil energy than the fuel produced.
* Wood biomass requires 57 percent more fossil energy than the fuel produced.

For biodiesel production, the study found that:

* Soybean plants requires 27 percent more fossil energy than the fuel produced.
* Sunflower plants requires 118 percent more fossil energy than the fuel produced.
