(AP) - General Motors says it has formed a partnership with a renewable energy company, a rare move by a major automaker into the production of non-fossil fuels.
The industry titan has taken an ownership stake with Coskata, a company with plans to produce ethanol from agricultural leftovers and municipal and industrial waste.
GM's chief executive says it will take more than 12 years to replace most of the vehicles on the road with more energy efficient ones.
He says if all the flex-fuel vehicles produced by major U.S. automakers, plus those the companies have committed to producing by 2010, were to run on ethanol, they would displace 29 billion gallons of gasoline annually.
The ethanol being developed by Coskata's technology won't be available at gas stations until the end of 2010 at the earliest.
