 Purchased
electricity was 13 percent higher in 1998 than it was in 1994. See Purchased
Expenditures.
Other
energy sources such as wood waste, hydrogen, or waste oils and tars, were
40 percent lower in 1998 as compared to 1994. With the exception
of the petroleum industry, the major industries--including food and primary
metals--had large reductions in these energy sources.
In
1998, almost one half (42 percent) of the utility-supplied electricity
was purchased by only three manufacturing industries--paper, chemicals,
and primary metals.

Notes:
See fuel consumption for a comparison
of net electricity using the 1998 SIC and NAICS classifications showing
very little difference in the estimates; all of the 1994-1998 comparisons
are statistically significant. Exceptions are noted by "NS."

In
1994 the chemical industry purchased most of the nonutility supplied electricity
(79%). In 1998, 90 percent of the nonutility supplied electricity
was purchased by other industries as the chemical industry's share fell
to 10 percent.
Although
electricity purchased from a nonutility was more than 3 times higher in
1998 than in 1994, it is still only 9 percent of the total.
Natural gas purchases have been deregulated for several years--in 1998,
68 percent of purchases came from nonutilities.
Steam purchases from nonutilities almost doubled--a growth in the outsourcing
of onsite steam production may have assisted this increase.
