Transportation accounts for approximately 25 percent of total U.S. energy consumption and about 60 percent of U.S. petroleum consumption. Practically all of this energy is in the form of petroleum products with very minor amounts of electric energy and natural gas. Thus, the transportation sector is very important in analyses of energy demand and the potential for energy conservation.

This report attempts to forecast the extent to which the manufacturing sector will economize in its use of scarce energy resources. Six industries are the primary focus of the report and include: paper and allied products; chemicals and allied products; stone, clay, glass, hydraulic cement, and glass containers; primary metals; and food and kindred products.
