Geothermal technology uses the earth’s natural thermal energy—a renewable resource—to heat your home. While outdoor temperatures fluctuate substantially with the seasons, subsurface ground and water temperatures remain relatively constant year–round. A geothermal loop, running underground or underwater, capitalizes on these constant temperatures.

In Nebraska, most ethanol is sold in a blended fuel–10 percent ethanol with 90 percent gasoline (called E–10) or 85 percent ethanol with 15 percent gasoline (called E85). 

As of July 2025, the rack price of ethanol was $1.82 versus $2.34 for unleaded 87–octane gasoline—a difference of 52 cents per gallon. The average ethanol rack price was three cents higher from last month's price but 17 cents lower from last year. Unleaded 87–octane gasoline's average rack price was three cents lower than last month's price and 34 cents lower from last year. Unleaded 84–octane gasoline's average rack price was two cents lower from last month's price and 35 cents lower from last year.

In Figure 1, the average annual rack prices for each type of fuel are shown.

In Nebraska, most ethanol is sold in a blended fuel—10 percent ethanol with 90 percent gasoline (called E–10) or 85 percent ethanol with 15 percent gasoline (called E85). Of the total gasoline and ethanol–blended fuel sold in the state in 2024, 85.6 percent was an ethanol blend. In Figure 1 and the data table below, the market share of ethanol–blended fuel is shown.
