Gas Could Be the Cavalry in Global Warming Fight

"It's cleaner than coal, cheaper than oil and a 90-year supply is under our feet."
It's natural gas, the same fossil fuel that was in such short supply a decade ago that it was deemed unreliable. It's now being uncovered at such a rapid pace that its price is near a seven-year low. Long used to heat half the nation's homes, it's becoming the fuel of choice when building new power plants. Someday, it may win wider acceptance as a replacement for gasoline in our cars and trucks.
Natural gas' abundance and low price come as governments around the world debate how to curtail carbon dioxide and other pollution that contribute to global warming. The likely outcome is a tax on companies that spew excessive greenhouse gases. Utilities and other companies see natural gas as a way to lower emissions—and their costs. Yet politicians aren't stumping for it.
Utilities in the U.S. aren't waiting for Washington to jump on the gas bandwagon. Looming climate legislation has altered the calculus that they use to determine the cheapest way to deliver power. Coal may still be cheaper, but natural gas emits half as much carbon when burned to generate the same amount of electricity.
Energy experts believe that the huge volume of supply now will ease price swings and supply worries.
"The question now is how does this change the energy discussion in the U.S. and by how much?" says Daniel Yergin, a Pulitzer Prize winning author and chairman of IHS CERA, an energy consultancy. "This is domestic energy. . .it's low carbon, it's low cost and it's abundant. When you add it up, it's revolutionary."
