The latest TIME cover story focuses on the pros and cons of pursuing America shale gas deposits to meet future energy needs.

Using new drilling methods pioneered by a Texas wildcatter, companies have been able to tap enormous quantities of gas from shale, leading to rock-bottom prices for natural gas even as oil soars. In a single year, the usually sober U.S. Energy Information Administration more than doubled its estimates of recoverable domestic shale-gas resources to 827 trillion cu. ft. (23 trillion cu m), more than 34 times the amount of gas the U.S. uses in a year. Together with supplies from conventional gas sources, the U.S. may now have enough gas to last a century at current consumption rates. (By comparison, the U.S. has less than nine years of oil reserves.)

Carolina Journal Radio listeners will recall that North Carolina government officials have been investigating this state’s shale gas potential.
