The year 2014 began slowly on its way down from the huge increase in consumption during the fall of 2013, but at the end of June, 2014, propane consumption for vehicle use for the first six months of the year totaled 1,075,865 gallons, over 3 times more than consumption during the same time period in 2013, which totaled 328,504 gallons. Even though there were significant drops in consumption in several months of 2014, at the year's end, propane consumption had jumped 48 percent higher compared to the year 2013the same time period of the previous year.
Propane consumption as vehicle fuel had been a bit bumpy from month to month during the 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.
In 2014, annual propane consumption for vehicle use was 2,102,622 gallons, which was 48 percent higher than consumption in 2013. In 2013, annual propane consumption for vehicle use was 1,422,839 gallons, which was more than double the consumption in 2012. For about six prior years to 2012, consumption fell each year. In 2012, annual propane consumption for vehicle use was 2 percent lower than consumption in 2011. In 2011, annual propane consumption for vehicle use was 29 percent lower than consumption in 2010. In 2010, annual propane consumption for vehicle use was 2 percent lower than consumption in 2009. Propane consumption in 2009 was 1 percent lower than consumption in 2008. Propane consumption in 2008 was 6 percent lower than consumption in 2007. Propane consumption in 2007 was 1 percent lower than consumption in 2006.
