Key figures (2022 Manufacturing Energy Consumption Survey, final results)
As of 6 November 2026, 00:58 KST (retrieved by this page at that time); most recently published results: the final results of the 2022 Manufacturing Energy Consumption Survey (MECS) from the U.S. Energy Information Administration (EIA), whose last data release was March 18, 2026; the highlights deck was last updated March 10, 2026. MECS is periodic, and the cited pages give no date for the next survey's results. Primary source: https://www.eia.gov/consumption/manufacturing/data/2022/pdf/2022%20MECS%20Results.pdf[1][2]

Comparison basis: values are as printed in EIA's 2022 MECS highlights, rounded as published (trillion Btu to whole numbers, shares to whole percents, dollars to one decimal in billions). MECS is not annual; the previous survey year is 2018. The single calculated change (+6.4%) is this page's, rounded half up to one decimal; EIA's text says 6%.[1]
In three lines
1. MECS is EIA's periodic survey of how U.S. manufacturing plants use energy, as fuel and as raw material.
2. In 2022, manufacturing first-use energy consumption was 20,687 trillion Btu, up 6% from 2018.
3. Manufacturers spent $191.7 billion on purchased energy, 40% of it by chemicals plants.[1]
What EIA says about the survey
Sample. MECS is a sample survey: EIA drew about 15,000 establishments from a national sample frame representing about 97% of manufacturing payroll. "We estimate the sample to represent at least that percentage of manufacturing energy consumption." Estimates with a relative standard error above 50% are withheld (marked Q). The cited pages describe establishments in the United States by census region and do not list territories. "EIA has conducted the MECS periodically since 1985." "The 2022 MECS is the 11th iteration."[1]
Fuel and nonfuel. Fuel consumption is the use of a substance burned for heat, power or electricity. "Nonfuel consumption is the use of energy as feedstock or raw material input." The 20,687 trillion Btu total is first-use consumption including nonfuel feedstock; it is not the amount of fuel burned, and 6.4 quadrillion Btu of it was nonfuel use.[1]
Expenditures. Expenditures are funds spent on energy purchased and paid for or delivered during the year. "For the MECS, expenditures include state and local taxes and delivery charges." They are payments for purchased energy, not a value placed on all energy used, which also includes energy produced and used onsite.[1]
Other definitions. For offsite-produced fuel: "It excludes fuel produced and consumed onsite, energy used as raw material input, and electricity losses." For fuel switching: "Fuel-switching capability does not depend on the relative prices of energy sources; it depends only on the characteristics of the equipment and certain legal constraints." On outside data: "Gross output estimates are sourced from the Bureau of Economic Analysis, Gross Output by Industry data series."[1]
Reading in pairs
First-use total vs offsite-produced fuel. First-use consumption was 20,687 trillion Btu, while offsite-produced fuel consumption was 12,060 trillion Btu; the 8,627 trillion Btu difference (this page's calculation) reflects the definitions: offsite-produced fuel excludes fuel produced and consumed onsite, energy used as raw material input and electricity losses.[1]
Two 74% figures. EIA's highlights give 74% twice. For spending, the expenditure chart shows the top five sectors as chemicals ($77.1 billion), petroleum and coal products ($26.3 billion), primary metals ($16.5 billion), food ($12.4 billion) and paper ($9.6 billion), which add to $141.9 billion, about 74.0% of the $191.7 billion total (this page's calculation); the accompanying sentence lists paper twice, as printed by EIA. For energy use, chemicals, petroleum and coal products, paper and primary metals held 74% of manufacturing energy consumption. One is a share of spending by five sectors and the other a share of energy use by four, so the two figures should not be treated as one.[1]
Energy use vs output. EIA reports manufacturing gross output up 19% from 2018 to 2022 against energy use up 6%, and energy intensity down 52% from 1998 to 2022. Gross output comes from the Bureau of Economic Analysis, not from MECS, so the comparison joins two sources.[1]
Survey rounds. First-use consumption was 22,394 trillion Btu in 2002, 18,834 in 2014, 19,436 in 2018 and 20,687 in 2022. Each round is a separate sample survey; the report does not establish why consumption fell and then rose.[1]
