Burning Food or Burning Fuel?

I was just reading and interesting article at organicconsumers.org (Corn to Ethanol) pertaining to the negative economic and social value of producing ethanol from corn. The article discusses the negative impact of the energy needed to produce just one gallon of ethanol and all the negative nuances that trickle down, one of the main things that resonated with me was the amount of fossil fuel needed to produce ethanol from corn is more than the end product of ethanol that will be created, so to clarify we/us (The U.S.) are burning more and more fossil fuel to produce much less ethanol. I was reading about this issue months ago when the chatter became amped up about alternative fuel sources and ethanol from corn was being played up in the media. I was skeptical that the source may have been some oil company consultant with an axe to grind over alternative fuels. But now I am starting to believe that ethanol from corn may not be the best way to go about the alternative fuel route, also I have read articles about ethanol being derived from switch grass and other weeds something in which we have plenty of in the US and may be worth looking into.
