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.
Total industrial sector expenditures on energy increased 13.0 percent to $2,043.9 million from 2010 to 2011. In 2011, the industrial sector spent $681.0 million for electricity, $603.1 million for diesel fuel, $483.2 million for natural gas, $95.3 million for motor gasoline, $65.4 million for propane, $57.1 million for asphalt and road oil, $35.2 million for coal, $13.6 million for lubricants, $7.1 million for other petroleum products (a definition is in the next paragraph), $2.7 million for wood and waste, and $0.1 million for kerosene. There were no consumption, prices, or expenditures reported for residual fuel. There were no direct fuel costs for hydroelectric, geothermal, wind, photovoltaic, or solar thermal energy. The cost for ethanol is not being tracked.
Other petroleum products included sixteen (16) separate products, all of which were assigned to the industrial sector. The sixteen products were: 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 varied from inexpensive (absorption oils similar to kerosene) to very expensive (hydraulic fluids) products. The greater part of the miscellaneous product line consisted of finished petrochemicals, especially the aromatic hydrocarbons: benzene, toluene, and the xylenes.
Nearly all of the money spent in the industrial sector on energy in 2011 went to petroleum products (41 percent), electricity (33 percent), and natural gas (24 percent) expenditures. Within the petroleum category, expenditures on diesel fuel comprised 30 percent of the total expenditures, motor gasoline expenditures were 5 percent, propane expenditures were 3 percent, and asphalt and road oil expenditures were 3 percent. Expenditures on each of the rest of the petroleum products were less than 1 percent. Coal expenditures were 2 percent of the total expenditures. Renewable energy expenditures were 0.1 percent of the industrial sector's energy expenditures; renewable energy expenditures were comprised of wood and waste.
The expenditures are in nominal dollars to provide a better comparison.
