ABSTRACT
Many of us still remember the fuel shortages of the 1970s with long lines at filling stations, and buildings under-heated or closed in the winter. Others remember, more nostalgically, gasoline prices of 32 cents per gallon and spending the evening driving around on a dollar's worth of gas. Gasoline at that price is long gone, probably never to return, and a return to the days of fuel shortages may be lurking just around the corner. Whatever our reasons, energy conservation should be an important part of our pollution control strategies. There are many things, both small and inexpensive and large and costly, that can be done to improve the manner in which we use this valuable resource. Transportation is by far the largest single energy-consuming sector of the economy. The US has made some strides in improving the fuel efficiency of automobiles, buses, trucks and airplanes, although recently there has been a trend away from fuel efficient cars.
