United States: Rethinking the American Dream

Biofuels (14/16)

U.S. President George W. Bush smells a bottle of ethanol as he tours Novozymes North America Inc. Bush recently proposed action to improve energy efficiency and independence. One of these policies is promoting wider use of biofuels. The Renewable Fuel Standard under the Energy Policy Act of 2005 mandates that a minimum of four billion gallons of renewable fuel must be used in the United States from 2006 on. Biofuels, however, are facing criticism due to uncertainty about how more ethanol production would affect agriculture and the environment. (Photo: Reuters)
