How Shale Gas Is Going to Rock the World

There's an energy revolution brewing right under our feet.

Over the past decade, a wave of drilling around the world has uncovered giant supplies of natural gas in shale rock. By some estimates, there's 1,000 trillion cubic feet recoverable in North America alone—enough to supply the nation's natural-gas needs for the next 45 years. Europe may have nearly 200 trillion cubic feet of its own.

We've always known the potential of shale; we just didn't have the technology to get to it at a low enough cost. Now new techniques have driven down the price tag—and set the stage for shale gas to become what will be the game-changing resource of the decade.

I have been studying the energy markets for 30 years, and I am convinced that shale gas will revolutionize the industry—and change the world—in the coming decades. It will prevent the rise of any new cartels. It will alter geopolitics. And it will slow the transition to renewable energy.

To understand why, you have to consider that even before the shale discoveries, natural gas was destined to play a big role in our future. As environmental concerns have grown, nations have leaned more heavily on the fuel, which gives off just half the carbon dioxide of coal. But the rise of gas power seemed likely to doom the world's consumers to a repeat of OPEC, with gas producers like Russia, Iran and Venezuela coming together in a cartel and dictating terms to the rest of the world.

The advent of abundant, low-cost gas will throw all that out the window—so long as the recent drilling catastrophe doesn't curtail offshore oil and gas activity and push up the price of oil and eventually other forms of energy. Not only will the shale discoveries prevent a cartel from forming, but the petro-states will lose lots of the muscle they now have in world affairs, as customers over time cut them loose and turn to cheap fuel produced closer to home.

The shale boom also is likely to upend the economics of renewable energy. It may be a lot harder to persuade people to adopt green power that needs heavy subsidies when there's a cheap, plentiful fuel out there that's a lot cleaner than coal, even if gas isn't as politically popular as wind or solar.
