In 2009, unconventional shale gas emerged as the dominant driver in North American natural gas markets. Rapid increases in shale gas production and shale-driven upward revisions to the U.S....
Coal No More: What If?
An analysis of what risks would have to be taken to significantly reduce carbon emissions by using natural gas in the short run.
 and should add to the sources of greater stability for natural-gas prices in 2006/2007.
From 1994 through 2004 there was only one year (1998) in which U.S. natural-gas replacement did not exceed—often by a considerable margin—annual production of 18-20 Tcf/yr (see Table 6, Parts 1 and 2). Moreover, 2005 should be a banner year with a record of 27,397 gas well completions and a record average active rig count of 1,186.
In any event, the electric power industry will have to use caution in making natural-gas-fired combined-cycle power generation its preferred choice to reduce carbon emissions and meet demand increases. The uncertain outlook for natural-gas supplies and prices calls for increased reliance on wind power and new light water nuclear power, as well as accelerated commercialization of the IGCC process modified to convert the output to a hydrogen-CO 2 mixture with CO 2 removal and sequestration.
