The stats on domestic natural gas are also eye-opening. Recoverable natural gas in North America is estimated at 4.2 quadrillion — or 4,244 trillion — cubic feet. At the current rate of consumption, that’s enough natural gas to power North America for the next 175 years. And it means that our continent has more robust gas reserves than Russia, Iran, Qatar, Saudi Arabia, and Turkmenistan — combined. Roughly 272.5 trillion cubic feet of that total are in the United States. … In the late 1990s, pundits were predicting a sharp uptick in natural gas prices due to a decline in reserves. Just a few years later, American production actually increased dramatically. The reason? Human imagination bred breakthrough technological innovation. Developers built new extraction tools, making it economical to tap into reserves buried in shale and other tight rock formations. (Forbes.com, Robert Bradley, 12/27/11)
