The question is not about peak oil, but just about consumption of gasoline by American drivers. Over the last several decades both miles driven and consumption of fuel have risen pretty steadily. However, one look at the automakers' sales numbers for the first half of 2008 clearly demonstrates that there is a fundamental shift in American behavior. The blend of gas over $4 a gallon and the general economic malaise has sent sales of the biggest, thirstiest vehicles into the toilet. People are also driving the vehicles that they have fewer miles than they have in previouis years. A new study by Cambridge Energy Research Associates indicates that the 2008 gasoline consumption will be lower than the 2007 peak and if oil prices stay at or near their current levels, gasoline consumption will continue to decline in the U.S. in the coming years and may never again reach 2007 levels. Combined with economic factors, the development of new vehicle
technologies will almost certainly continue to drive gasoline use downward although, it will likely remain a significant portion of our transportation system for many years to come.
