In 2005, Congress passed a law (RFS) requiring that gasoline sold by refiners, importers and blenders must contain an increasing amount of renewable fuel, such as ethanol or biodiesel, starting at 4 billion gallons in 2006, increasing each year by 700 million gallons, and reaching a level of 7.5 billion gallons in 2012.
If that wasn't bad enough, in 2007, Congress passed RFS2 requiring refiners, etc, to blend in 36 Billion gallons of renewable fuels (think ethanol) into gasoline by 2022 or the equivalent of 26% ethanol.
What is gut wrenching sick about this is the corn lobby spent $millions buying votes to pass these laws when corn based ethanol does not reduce our need to import
oil.
