"Estimate Places Natural Gas Reserves 35% Higher"

"Thanks to new drilling technologies that are unlocking substantial amounts of natural gas from shale rocks, the nation's estimated gas reserves have surged by 35 percent, according to a study due for release on Thursday.

The report by the Potential Gas Committee, the authority on gas supplies, shows the United States holds far larger reserves than previously thought. The jump is the largest increase in the 44-year history of reports from the committee.

The finding raises the possibility that natural gas could emerge as a critical transition fuel that could help to battle global warming. For a given amount of heat energy, burning gas produces about half as much carbon dioxide, the main cause of global warming, as burning coal."
