General Motors (Charts), Ford (Charts) and DaimlerChrysler (Charts) recently announced plans to double their annual production of so-called flex fuel vehicles to two million cars and trucks by 2010.
It's the single largest commitment to renewable fuels in the history of the auto industry - a good move for the automakers, and for the planet, too.
That's because running cars and trucks on E85, a blend of 85 percent ethanol and 15 percent gasoline, could turn out to be a cost-effective way to reduce the carbon emissions that cause global warming and curb our dependence on imported oil.

Several reasons. First, selling ethanol could be a new profit center for Wal-Mart, since the retailing business is wide-open. It's also a way for the company to help its customers save money; the less money they pour into the tank, they more they have to spend at Wal-Mart.
Finally, Wal-Mart's interest in alternative fuels like ethanol comes as part of its sweeping efforts to adopt business practices that are better for the environment. To guide its efforts, Wal-Mart has organized more than a dozen "sustainable value networks" that are composed of suppliers, environmentalists, industry experts and government officials.
