Millions of acres of marginal farmland in the Midwest — land that isn't in good enough condition to grow crops — could be used to produce liquid fuels made from plant material, according to a study in Nature. And those biofuels could, in theory, provide about 25 percent of the advanced biofuels required by a 2007 federal law.

Wind isn’t the only alternative energy industry to get a boost from the Fiscal Cliff deal. Also included is a tax credit for algae growers encouraging biofuel production that could one day power cars and boats.
