Here's an excellent article that cuts through the hype on bio-fuels, and explores why their use is being pushed so hard with fraudulent environmental and economic claims. It appears the Bush admin is acting in the interests of the oil companies (insert shock here).

Bush's BioFuel Hidden Agenda
This year the Massachusetts Institute of Technology issued a report concluding that using corn-based ethanol instead of gasoline will have no impact on greenhouse gas emissions, and would even expand fossil fuel use due to increased demand for fertilizer and irrigation to expand acreage of ethanol crops. And according to MIT "natural gas consumption is 66% of total corn ethanol production energy," meaning huge new strains on natural gas supply, pushing prices there higher.

The idea that the world can "grow" out of oil dependency with bio-fuels is the PR hype being used to sell what is shaping up to be the most dangerous threat to the planet's food supply since creation of patented genetically manipulated corn and crops.
