During the first six months of 2017, compressed natural gas (CNG) consumption for vehicle use was above the five–year range until May and June. During May and June, consumption was lower but still near the upper boundary of the five–year range.
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 from 2012 to the present. See Henry Hub data for spot price information.
The number of vehicles consuming compressed natural gas can be found in the report The Number of Registered Vehicles in Nebraska by the Fuel Consumed.
