Action that President Barack Obama will take Monday to allow California and other states to require stricter tailpipe emissions and automobile fuel efficiency standards shouldn't just please environmentalists.

If you're concerned about Peak Oil and the United States' dependence on foreign oil, this is also a win for energy conservation. This could be a market force that Detroit cannot ignore, pushing fuel efficiency farther faster. Conservation isn't everything, but for a society so totally unprepared, it's one span in the bridge to the energy future.

The New York Times is reporting tonight that President Barack Obama will reverse Bush Administration environmental policy tomorrow and allow California and other states to mandate their stricter rules.

California Gov. Arnold Schwarzenegger had requested and been denied by the U.S. Environmental Protection Agency in 2007 a waiver to set California automobile emission standards higher than federal guidelines. The Bush Administration told California and several other states that 2007 increases in federal fuel efficiency guidelines for cars and light trucks made their efforts moot and that a national patchwork of differing emissions laws would be untenable.

This is a win not only for environmentalists but also those concerned about the Peak Oil crisis and America's continued over reliance on fossil fuels. The stricter standards set by states will be a market force that the Big Three and other automakers will not be able to ignore. According to the Times' reporting, California's action alone could have a great effect on fuel efficiency in the nation's car and truck fleet:

The California law, which was originally meant to take effect in the 2009 model year, requires automakers to cut emissions by nearly a third by 2016, four years ahead of the federal timetable. The result would be an increase in fuel efficiency in the American car and light truck fleet to roughly 35 miles per gallon from the current average of 27.

In order to deal with the strategic, economic and societal changes which will brought on by a world where oil is harder to find and harder to extract, the U.S. and other nations will need to build bridges to the next energy economy. Actions such as the one Obama will take on Monday will make it easier to build the "conservation" span of our nation's bridge.

One question remains -- will the Big Three automakers fight this in court? Probably, but they should be shamed out of the courthouse. U.S. taxpayers are keeping two out of three of them afloat. They should be discouraged from using our cash to fight our government ...
