<P> The largest volume held in storage was 8.29 trillion cubic feet in October 2012 . This was equivalent to 26 percent of the total US production in 2014 . The small mid-summer increase shown on the consumption graph is due to increased gas use for electrical power in the summer . Unlike residential, commercial, and industrial use, all of which are higher in winter, electrical power generation uses more gas in the summer . </P> <P> From the processing plant, natural gas is sold mostly to gas utility companies . In 2014, 46% of the marketed gas was used by commercial and industrial users, 33% by electrical power generators, and 21% by residential consumers . </P> <P> Since 2009, electricity generation has been the largest use of natural gas in the US . Electricity generated by natural gas has been by far the fastest - growing source of electricity in the US since the 1990s . Natural gas became the second - largest source of US electricity in 2006, when it surpassed nuclear power . In late 2015, natural gas surpassed coal as the largest source of electricity generated in the United States . </P> <P> In the decade 2005 to 2015, electricity generated by natural gas increased by 574 billion kilowatt - hours, more than triple the increase of the second - fastest - growing source, wind energy, which increased 173 billion kilowatt - hours over the same period . Natural gas - generated electricity increased its share of total US electricity from 18.8 percent in 2005, to 32.6 percent in 2015 . The increase in gas - generated electricity was mostly at the expense of coal power, which fell from 49.6 percent of US electricity in 2005, to 33.2 percent in 2015 . Natural gas surpassed coal as the number one generator of US electricity in late 2015 . During the 12 - month period through August 2016, natural gas generated 34.5 percent of US electricity, versus 29.8 percent for coal . </P>
