I just received the following from a friend that is in the business of testing and designing additives for biofuels. Found it interesting.
Unintended Consequences
Biofuel Crops Actually Increase Carbon Dioxide Emissions according to two studies conducted by the University of Minnesota (a state that mandates using B2) and Princeton University
Converting existing farmland from food to biofuel increases greenhouse gases as food production is shifted to other parts of the world OR worse that rain forests are cleared to produce biofuels
A US cornfield devoted to producing ethanol would have to be farmed for 167 years to achieve a net reduction in emissions
Cutting down a tropical rainforest in Brazil to grow soybeans increases emissions for 319 years
Clearing an Indonesian peat land rainforest to make way for a biofuels plantation releases so much carbon that a net reduction in emissions would not begin for 423 years
