From Investor's Business Daily:
If estimates hold up, energy experts say the shale gas that underlies large parts of the United States will be able [to] meet our country's needs for the next 100 years. The Department of Energy expects shale gas to account for 50% of natural gas production by 2020 if not sooner.
What's more, the same drilling techniques for shale gas are now being used in several European countries, including France and Poland, to extract their own supplies. Both China and India have huge shale-gas resources. Geologists say shale gas is so plentiful in some parts of the world that it could meet global needs for several centuries.
