Even though there were significant drops in consumption in April and June of 2014, propane consumption had more than doubled compared to the same time period of the previous year. At the end of June, 2014, propane consumption for vehicle use for the first six months of the year totaled 1,075,865 gallons while consumption during the same time period in 2013 totaled 328,504 gallons. The year 2014 began slowly on the way down from the huge increase in consumption during the fall of 2013.
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 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.
