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 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.

How much carbon dioxide is emitted by the average U.S. car driving one mile?

  • Sorry, that’s incorrect.

    The average U.S. car gets 21.4 mpg. About 19 pounds of carbon dioxide are emitted for every gallon burned, or 0.9 lb/mile.

Energy Defined

Climate Change

The process of shifting from one prevailing state in regional or global climate to another. Often used interchangeably with “global warming,” scientists sometimes also use the term to refer to periods of climatic cooling. Climate change is typically the preferred term over “global warming” because it helps convey that there are climate changes in addition to rising temperatures.
