PATTERNS OF FUEL SUPPLY AND DEMAND

This section presents statistical data for the U.S. patterns of fuel supply and demand (SRI 1972) in 1968 and projections for these patterns for 1985 (Dupree and West 1972). Although many projections have been made for 1985, for the purposes of this report, we will consider only the projections of the U.S. Department of the Interior (Dupree and West 1972).

In 1968, the amount of fuel consumed in the U.S. was about 57 quads (1 quad=1015 Btu) exclusive of about 3 quads used as feedstock materials. It was distributed among the fuel sources approximately as follows:

Petroleum products

43.5%

Coal

23.0%

Natural Gas

32.0%

Nuclear and hydrostatic head

1.5%

 

100%

It was consumed in the major sectors of the economy in the amounts shown in the first and second columns of Table 9–1, namely 41 percent in the industrial sector, 34 percent in the residential and commercial sector, and 25 percent in the transportation sector. Some of the fuel was consumed in the form of electricity (columns 3 and 4, Table 9–1) which was primarily (92 percent) from utilities and to a lesser degree (8 percent) generated as by-product of industrial processes. The fuels used in electricity generation were 53.5 percent coal and 46.5 percent others.

The principal end-uses of fuels in industry in 1968 can be classified in the four major catagories shown at the bottom of Figure 9–1 among which the fuels are distributed as follows:
