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.
Using an equivalent measure of million British thermal units (Btu), the graph below compares the prices of fuel. The prices are also in nominal dollars to provide a better comparison. In 2015, the highest price was for lubricants at $67.28 per million Btu. The price of electricity was $22.25, motor gasoline was $19.80, petroleum products in the 'other petroleum' category was $17.53 (see definition in next paragraph), kerosene was $17.07, propane was $16.61, diesel fuel was $14.95, asphalt and road oil was $12.02, natural gas was $4.31, wood and waste was $1.87, and coal was $1.71. The price of residual fuel was not reported.
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.
The price for ethanol is not tracked, and there are no direct fuel costs for hydroelectric, geothermal, wind, photovoltaic, or solar thermal energy, so no prices were reported.
