[[fossil energy]]
Ethanol is also a [[biofuel]] made from [[alcohol]] and is an [[oxygenate]] that is added to [[gasoline]] to increase the [[octane]] rating. The product is produced through the [[fermentation]] of [[corn]], or other cellulosic material.
However, it is not economically viable as a fuel: "corn requires 29% more [[fossil energy ]] than the fuel produced". [http://www.globalwarminghoax.com/news.php?extend.7]
