Scott Grannis points to this excellent Salon article "Everything You've Heard About Fossil Fuels May Be Wrong" about natural gas and fracking, here are some excerpts:

"According to the conventional wisdom, the U.S. and other industrial nations must undertake a rapid and expensive transition from fossil fuels to renewable energy for three reasons: The imminent depletion of fossil fuels, national security and the danger of global warming. What if the conventional wisdom about the energy future of America and the world has been completely wrong?

The U.S., Canada and Mexico, it turns out, are sitting on oceans of recoverable natural gas. Shale gas is combined with recoverable oil in the Bakken "play" along the U.S.-Canadian border and the Eagle Ford play in Texas. The shale gas reserves of China turn out to be enormous, too. Other countries with now-accessible natural gas reserves, according to the U.S. government, include Australia, South Africa, Argentina, Chile, France, Poland and India.

Because shale gas reserves are so widespread, the potential for blackmail by Middle Eastern producers and Russia will diminish over time. Unless opponents of fracking shut down gas production in Europe, a European Union with its own natural gas reserves will be far less subject to blackmail by Russia. The U.S. may become a major exporter of natural gas to China -- at least until China borrows the technology to extract its own vast gas reserves.

Two arguments for switching to renewable energy -- the depletion of fossil fuels and national security -- are no longer plausible.

The arguments for converting the U.S. economy to wind, solar and biomass energy have collapsed. The date of depletion of fossil fuels has been pushed back into the future by centuries -- or millennia. The abundance and geographic diversity of fossil fuels made possible by technology in time will reduce the dependence of the U.S. on particular foreign energy exporters, eliminating the national security argument for renewable energy.
