ENERGY USE IN INDUSTRY/MANUFACTURING

The United States is highly industrialized. Industry accounts for about one-third of the energy used in the country.

There are many different uses and a variety of different energy sources in the manufacturing sector. One main use is as boiler fuel, which means producing heat that is transferred to the boiler vessel to generate steam or hot water. Another use is as process heating, which is when energy is used directly to raise the temperature of products in the manufacturing process; examples are separating components of crude oil in petroleum refining, drying paint in automobile manufacturing, and cooking packaged foods.

Major End Uses of Some Common Energy Sources
(Percent of Energy Source Used for an End Use)

Industrial Distillate Fuel Oil Uses
Process Heat 13 percent
Boiler Fuel 26 percent
Other 61 percent

Industrial Electricity Use
Machine Drives 51 percent
Other 49 percent
Industrial Coal Use:
Boiler Fuel 69 percent
Other 31percent
Industrial Natural Gas Use:
Process Heat 48 percent
Boiler Fuel 38 percent
Other 14 percent

TYPES OF ENERGY FOR INDUSTRY/MANUFACTURING

In the manufacturing sector, the predominant energy sources are natural gas and electricity (a secondary source). Manufacturers also use other energy sources for heat, power, and electricity generation. Many uncommon energy sources are also used by manufacturers as a feedstock(a raw material used to make other products).

Sources of Energy Used for Industry and Manufacturing

TYPES OF ENERGY USED IN INDUSTRIAL AND MANUFACTURING
Natural Gas 38 percent
Other Sources 32 percent
Electricity 17 percent
Coal 6 percent
Fuel Oil 3 percent
Coke & Breeze 4 percent
LPG 1 percent.

ENERGY USE BY TYPE OF INDUSTRY

Every industry uses energy, but there are a handful of energy-intensive industries that use the bulk of the energy consumed by the industrial sector.

The chemical industry is the largest industrial consumer of energy, followed closely by petroleum refining. The refining, chemical, paper and metal industries together use:

94% of the feedstock
92% of the byproduct energy
70% of total inputs of energy for heat, power, and electricity generation
