With the exception of February and March, propane consumption for vehicle use in 2019 was very comparable to 2018. Consumption started just under last year's point, under the five–year (2014-2018) average, and in the lower boundary of the five–year (2014-2018) range. From February through March, consumption stayed below the five–year average, the five-year range, and 2018's consumption. In July, consumption had a huge drop but it stayed in the center of the five–year range and at the five–year average, but above 2018's consumption. Consumption bounced back in August, peaking in October, although October was at the lower boundary of the five-year range and far below the five-year average and 2018's consumption. The year ended below 2018's consumption and the five-year average and in at the lower boundary of the five-year range. All of this can be seen in Figure 1 below.
According to the data table below, propane consumption as vehicle fuel had been a bit bumpy from month to month during past years and annual totals had been declining. In the latter half of 2013, though, consumption skyrocketed in August and September. Consumption did drop in October and November but did not return to previous year levels. Each month's consumption for October, November, and December remained above 200,000 gallons. During the fall of 2013, Nebraska and surrounding states experienced late harvest at the same time. Shortly after harvest was completed, cold weather set in. These two back–to–back events occurring in the region, not just the state, increased propane demand and lowered propane supplies. Consumption in 2014 to 2016 were double the consumption of previous years. Annual consumption in 2017, 2018, and 2019 dropped 12 percent, 2 percent, and 2.6 percent, respectively, from the prior year.
