Industry

About one-third of the energy used in the United States in 2006 went to industry. That’s not so surprising when you consider everything that falls under this economic sector. Every product we rely on—from aluminum cans to fertilizer to glass to paper products—takes energy to produce. The use of energy in industry affects every single citizen personally through the cost of goods and services, the quality of manufactured products, the strength of the economy, and the availability of jobs.

The industrial sector uses energy in many ways. Often energy is needed directly to raise the temperature of components in the manufacturing process, which is called process heating. Refining crude oil, where heat is used to separate various products, is an example of this. Another common use of energy in industry is to heat a boiler that generates steam or hot water.

Natural gas and oil are heavily relied upon in industry and manufacturing. Electricity, a secondary energy source, is also critical for powering operations. (Explore Our Energy System to see how industry fits into the big energy picture.) While a broad range of activities is included in this sector, a few stand out as the biggest energy users. The chemical, forest products, and petroleum refining industries draw a large amount of energy, as do aluminum, glass, metal casting, mining, and steel. In fact, those industries consume about 75% of the energy used by this sector. For this reason, many efforts to improve the nation’s energy efficiency focus on industry and manufacturing.

Energy Defined

Global Warming

A term used to describe the phenomenon of Earth’s rising average near-surface temperature. Although such fluctuations have occurred in the past due to natural causes, the term is most often used today to refer to current warming trends. Most scientists have concluded that this is very likely due to the observed increase in human-generated greenhouse gas concentrations in the atmosphere.
