Why should the gas lines of the 1970s become a permanent part of American life in the 1980s? The international energy system is now so precariously balanced that a critical supply interruption can occur at any time. Gasoline rationing could be the immediate response in a new crisis. But is the United States ready? This volume analyzes these urgent issues. It is the result of a special symposium of the nation's leading experts convened by the International Energy Seminar at Harvard's Center for International Affairs to explore the various options for reshaping gasoline demand. There is no easy answer, but the worst course is to do nothing. If we are to solve the dependence dilemma, we must do it ourselves.
