Nebraskans spent more than eleven times as much on energy in 2020 as was spent in 1970. The amounts spent on energy in 2020 and in 1970 accounted for 6.9 percent and 11.5 percent, respectively, of consumer income. Looking at Figure 1, before the oil embargo of 1973–74, annual energy expenditures were roughly an 11–percent share of personal income. During the price shocks of the 1970s and early 1980s, energy's percent share of income rose to peak at 16.6 percent. Each year after peaking, the percentage steadily fell until it was under 10 percent. The percentage went as low as 7.7 percent in 1999. Then in 2000, the percentage started rising, and in 2005, energy's percent share of income was in double digits again. In 2009, the percentage dropped 20 percent from 2008 to 10.0 percent—a major factor was the decrease in energy prices. After that, the percentage was stable around 12 percent. In 2015, the percentage dropped to 8.5 percent due to a decrease in energy prices. From then on, the percentage was stable between 8.0 percent and 9.0 percent until 2020, when the percentage dropped to 6.9 percent. This was possibly due to COVID.
