Nebraska's total energy consumption in 2015 was 853 trillion British thermal units (Btu), which was a 1.9 percent decrease from 2014. Total energy consumption is consumption of primary resources and end–use energy. According to the Energy Consumption Comparison by State report, Nebraska had the 19th lowest energy consumption in the country, which was less than one percent (0.88 percent) of the nation's total consumption. Using energy consumption per capita for comparison, Nebraska was the 44th lowest or the 7th highest in the country.
Primary resource consumption includes energy used in the generation of electricity whether that electricity is used in Nebraska or not. In 2015, consumption of primary energy resources was 939.14 trillion Btu, which was a 0.4–percent decrease from 2014.
End–use energy consumption refers to the energy content of electricity and other fuels at the point of use by consumers. Unless otherwise noted, total energy consumption refers to total primary energy consumption adjusted for net interstate sales of electricity. Net interstate sales represent the difference between the energy in electricity sold, including the associated losses, and the energy input at electric utilities in Nebraska. Net interstate sales will be a negative number if Nebraska sold, or exported, electricity; and net interstate sales will be a positive number if Nebraska had to buy, or import, electricity. A percentage of the primary energy used to generate and distribute electricity is lost as waste heat. This loss is referred to as associated energy losses or electric system losses.
In 2015, Nebraska's energy needs were met by coal (28.4 percent), petroleum (25.1 percent), natural gas (18.1 percent), renewable energy (16.9 percent), and nuclear electric power (11.5 percent). See pie chart just below. In the area graph farther below, hydroelectric power is broken out of renewable energy. (To see a pie chart of electricity generation fuels, go to the Annual Electricity Generation by Fuel Type report.)
From 2014 to 2015, nuclear electric power use increased 2.2 percent and renewable energy use increased 9.4 percent. From 2014 to 2015, coal use decreased 3.7 percent, petroleum use decreased 0.14 percent, and natural gas use decreased 5.2 percent.
