Do you have a link to this article? In their issue "The Truth about Biofuels", they report that "Cynics claim that it takes more energy to grow corn and distill it into alcohol than you can get out of the alcohol. However, according to the DOE, the growing, fermenting and distillation chain actually results in a surplus of energy that ranges from 34 to 66 percent." It seems that that includes these other costs.
While we do all this, the corn which was feeding the cows and chickens from which Mickey D's feeds half the population; will run out of burgers and strips!
