What's Right with Biofuels

From Business Week, "In addition, greenhouse gas analyses of burning soy- and canola-based biodiesel are quite favorable. A definitive study conducted by the U.S. Energy Dept. shows that biodiesel cuts carbon emissions by 78% compared with petroleum diesel. And for every unit of energy that goes into making biodiesel, we get 3.5 units of energy in return....

...But perhaps the greatest weakness in the recent critiques of biofuel sustainability is a failure to address the many shortcomings of sticking with petroleum. Quenching the world population's growing thirst for fuel requires oil companies to use more invasive production methods, more energy to extract it, and more land—including pristine ecosystems."
