The proposed federal energy bill, currently back in committee for further debate, has targeted a dramatic increase in the use of renewable fuel sources, and that has helped focus a vast amount of attention on ethanol over the past year. By 2012, five billion gallons of renewable fuels would make up part of the nation’s fuel supply. That is nearly double the current amount of ethanol in use.
