If Americans aren’t motivated by environmental concerns they are at least moved to action, or in this case into just staying home, by the damage to their pocket book.

The Department of Transportation said figures from March show the steepest decrease in driving ever recorded.

Compared with March a year earlier, Americans drove an estimated 4.3 percent less — that’s 11 billion fewer miles, the DOT’s Federal Highway Administration said Monday, calling it “the sharpest yearly drop for any month in FHWA history.” Records have been kept since 1942.

According to AAA, for the first time since 2002, Americans said they were planning to drive less over the Memorial Day weekend than they did the year before.

Hopefully gas will hit $15 per gallon and then America will be the greenest country on the planet. Meanwhile others are claiming peak oil to be a hoax and blame rising prices on market manipulations.

Washington is trying to shift blame, as always, to Arab oil producers and the Organization of Petroleum Exporting Countries (OPEC). The problem is not a lack of crude oil supply. In fact, the world is in over-supply now. Yet the price climbs relentlessly higher. Why? The answer lies in what are clearly deliberate US government policies that permit the unbridled oil price manipulations.

The world is not in over-supply, if growth continues exponentially as it has in the past, we positively have reached ‘peak oil’. Yes, prices are being manipulated to the benefit of big oil and to the detriment of almost every other industry but what these reports show is conservation, more than any other tactic, renewable resource or, gasp, nuclear power, will have the biggest impact on the economy and the environment.
