Everything you've heard about fossil fuels may be wrong.

CORRECTION: Everything you've heard about fossil fuels may be IS wrong.

As everyone who follows news about energy knows by now, in the last decade the technique of hydraulic fracturing or "fracking," long used in the oil industry, has evolved to permit energy companies to access reserves of previously-unrecoverable “shale gas” or unconventional natural gas. According to the U.S. Energy Information Administration, these advances mean there is at least six times as much recoverable natural gas today as there was a decade ago.

Natural gas, which emits less carbon dioxide than coal, can be used in both electricity generation and as a fuel for automobiles.

The implications for energy security are startling. Natural gas may be only the beginning. Fracking also permits the extraction of previously-unrecoverable “tight oil,” thereby postponing the day when the world runs out of petroleum. There is enough coal to produce energy for centuries. And governments, universities and corporations in the U.S., Canada, Japan and other countries are studying ways to obtain energy from gas hydrates, which mix methane with ice in high-density formations under the seafloor. The potential energy in gas hydrates may equal that of all other fossils, including other forms of natural gas, combined.

If gas hydrates as well as shale gas, tight oil, oil sands and other unconventional sources can be tapped at reasonable cost, then the global energy picture looks radically different than it did only a few years ago. Suddenly it appears that there may be enough accessible hydrocarbons to power industrial civilization for centuries, if not millennia, to come.
