The industrial sector consists of manufacturing, construction, mining, agriculture, and forestry organizations. Energy used by this sector to transport products to market or inputs to the organizations is included in the transportation sector.
For the residential, commercial, and industrial sectors, a net total or net energy consumption (less electrical system energy losses) is provided to indicate the energy actually consumed by these sectors. In addition, energy consumed in the generation, transmission, and distribution of electricity (electrical system energy losses) is allocated to each sector based on the electricity consumed by the sector. Thus, total energy consumption represents the energy consumed by the sector as well as that used to provide electricity to the sector.
Between 2010 and 2011, industrial sector net energy use increased 6.9 percent to 291.7 trillion British thermal units (Btu). Total energy consumption attributed to the industrial sector in 2011 was 371.9 trillion Btu, an increase of 6.0 percent from 2010. Petroleum use decreased 2.2 percent. Coal use increased 49.5 percent, renewable energy use increased 10.2 percent, electricity use increased 3.7 percent, and natural gas use increased 1.8 percent from 2010. Renewable energy consumption was comprised of ethanol, losses and co–products, and wood and waste.
In 2011, almost all of the industrial sector energy needs were met by renewable energy (38.9 percent), natural gas (30.0 percent), electricity (12.4 percent), and petroleum products (12.2 percent). Six point five (6.5) percent of the energy consumed in the industrial sector was coal. The majority of the petroleum products consumed by the industrial sector were diesel fuel (67.4 percent), asphalt and road oil (14.9 percent), motor gasoline (9.0 percent), and propane (7.5 percent); the rest of the products each comprised less than one percent.
Other petroleum products include sixteen (16) separate products, all of which are assigned to the industrial sector. The sixteen products are: aviation gasoline blending components; crude oil; motor gasoline blending components; natural gasoline, including isopentane; pentanes plus; petrochemical feedstocks, naphtha; petrochemical feedstocks, other oils; petrochemical feedstocks, still gas; petroleum coke; plant condensate; special naphthas; still gas; unfinished oils; unfractionated streams; waxes; and miscellaneous. Miscellaneous products vary from inexpensive (absorption oils similar to kerosene) to very expensive (hydraulic fluids) products. The greater part of the miscellaneous product line consists of finished petrochemicals, especially the aromatic hydrocarbons: benzene, toluene, and the xylenes.
