There's a long and thorough going piece over on Farm Futures about the Biofuel Smear Campaign. I'm not sure that I agree with it entirely. It is based on the US experience, and that as far as it goes is OK. In the US the price of food is only partly determined by the price of food based ingredients, if food is processed then energy is used to do the processing. So the rising price of corn (up 67% in two years) is less important in the price paid by the consumer of a box of breakfast cereal fortified with sugar, salt and 97 vitamins, than it is to people who mill their own grains to make their food directly.
That said. I like the parts about US Farm policy and the sign off paragraph, which I could have written myself.
Biofuels are not a perfect answer to the problem. They are only one piece of the puzzle. But to dismiss their potential impact on foreign oil dependence is short-sighted at best. There is no more cheap petroleum in the world. American consumers need to wake up and realize the goal to move beyond oil is attainable, but not without a change in attitude and yes, some sacrifice.
