Gas could be the cavalry in global warming fight

An unlikely source of energy has emerged to meet international demands that the United States do more to fight global warming: 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.
