In the US in 2013 we planted 77.2 million acres of Soybeans. Of that, 10.9 million acres were used for Bio-diesel (14%). (Source HERE--I did the calculations for acres based on data given for bushels per acre. Data on Soybean for bio-diesel HERE)
The total number of acres used to grow "food for fuel" was 48.68 million acres. That is 28% of the total planted Corn and Soybean crop.
How much is 48.68 million acres?
The State of Nebraska is a little over 49 million acres. In other words, we have an energy and agricultural policy that diverts the whole State of Nebraska to producing fuel instead of food.
