Nebraska's total expenditures on energy increased 14.8 percent to $9,971.2 million (or $10.0 billion) from 2010 to 2011. The first table below shows that, in 2011, $6,545.0 million (or $6.5 billion) was spent on petroleum, $1,073.8 million (or $1.1 billion) was spent on natural gas, $437.9 million was spent on coal, $48.8 million was spent on nuclear fuel, and $14.1 million was spent on renewable energy. Wood and waste make up the cost associated with renewable energy since there are no direct fuel costs for hydroelectric, geothermal, wind, photovoltaic, or solar thermal energy and expenditures on ethanol were not tracked this year.
Expenditures on petroleum were over half (65.6 percent) of Nebraska's total expenditures on energy in 2011 with natural gas comprising the other major portion (10.8 percent). Four and four–tenths percent (4.4%) of Nebraska's expenditures were spent on coal, 0.49 percent was spent on nuclear fuel, and 0.14 percent was spent on renewable energy.
Petroleum is divided into ten fuels or categories of fuels, as shown in the second table below: distillate fuel (46.8 percent), motor gasoline (44.4 percent of petroleum), propane (4.15 percent), lubricants (1.95 percent), jet fuel (1.65 percent), asphalt and road oil (0.87 percent), other petroleum (0.11 percent), aviation gasoline (0.11 percent), kerosene (0.005 percent), and residual fuel (0.002 percent). Other petroleum includes 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.
