Interesting story on the connection between farming, energy and midwestern primary elections on the Des Moines Register yesterday.
Good to see that there is talk of fuel efficiency in at least one of the bills. The US is going to use around 177 000 million gallons of gasoline this year, its already using 20% of the corn crop to produce around 5000 million gallons of ethanol via fermentation. That cannot be unless there is a big change in consumption, the volume of corn that will be used in the short term will become unsustainable pretty quickly. Of course auto engines need to change to accept higher ethanol blends... and the fuel needs to be more widely available.
