Each of the prior four years had started anywhere from 50 percent higher to nearly 3 times higher than the prior year. This was no different for the year 2016. The year 2016 started 64% higher than the year 2015. What is different from previous years is that consumption in the year 2016 has been stable between 100,000 gallons and 140,000 gallons.

At the end of June, 2016, CNG consumption for vehicle use for the first six months of the year totaled 713,698 gallons, which was 30 percent higher than the amount of consumption in the first six months of 2015 (547,649 gallons). At the end of June, 2015, CNG consumption for vehicle use for the first six months of the year totaled 547,649 gallons, which was 56 percent higher than the amount of consumption in the first six months of 2014 (350,532 gallons). Consumption in 2014 climbed steadily higher through the year to a peak of 78,544 gallons in October. November's consumption dropped to 50,630 gallons, but bounced back in December to 70,774 gallons. At the year's end, CNG consumption for 2014 had jumped 67 percent higher than 2013's consumption.

The amount of compressed natural gas (CNG) consumed as vehicle fuel had been relatively stable from month to month during 2006 to mid-2011 with a bit of volatility thrown in in the summer and fall months. During August and September of 2011, CNG experienced a spike in consumption and then consumption skyrocketed in November and December. This increase in consumption was due to the drop in natural gas prices. Significantly lower natural gas prices continued into 2012, 2013, 2014, and 2015 and consumption continued to soar.

In 2016, annual CNG consumption for vehicle use was 1,419,612 gallons, which was 11 percent higher than consumption in 2015. In 2015, annual CNG consumption for vehicle use was 1,280,348 gallons, which was 70 percent higher than consumption in 2014. In 2014, annual CNG consumption for vehicle use was 753,561 gallons, which was 67 percent higher than consumption in 2013. In 2013, annual CNG consumption for vehicle use was 451,999 gallons, which was 70 percent higher than consumption in 2011. In 2012, annual CNG consumption for vehicle use was 267,475 gallons, which more than tripled consumption in 2011. In 2011, annual CNG consumption for vehicle use was 85,611 gallons, which was 87 percent higher than consumption in 2010. In 2010, annual CNG consumption for vehicle use was 45,891 gallons, which was 10 percent lower than consumption in 2009. CNG consumption in 2009 was three percent higher than consumption in 2008. CNG consumption in 2008 was eight percent higher than consumption in 2007. CNG consumption in 2007 was 21 percent lower than consumption in 2006.
