Is Fracking Good for the Environment?

“Is increased production of natural gas from shale deposits good for the environment? At first glance, yes: natural gas releases less CO2 into the atmosphere than coal, so replacing coal-fired electrical plants with gas-fired plants is a win for global warming. And since fracking makes natural gas cheaper, it helps stimulate a switch from coal to gas.

But wait: It turns out you also have to account for leakage. The problem is that natural gas is methane, a powerful greenhouse gas in its own right, and when you extract natural gas from shale formations, some of it inevitably leaks out. That’s decidedly badfor global warming. But David McCabe, an atmospheric scientist at the Clean Air Task Force, reports that the news is fairly good on this front:” “From the best of the collective work, we believe that burning natural gas for electricity produces about 30-50% less greenhouse gas than burning coal, even accounting for the emissions of methane (and carbon dioxide) from producing and transporting the natural gas.”

Regulation Is Lax for Water From Gas Wells

“The American landscape is dotted with hundreds of thousands of new wells and drilling rigs, as the country scrambles to tap into this century’s gold rush — for natural gas.

“The gas has always been there, of course, trapped deep underground in countless tiny bubbles, like frozen spills of seltzer water between thin layers of shale rock. But drilling companies have only in recent years developed techniques to unlock the enormous reserves, thought to be enough to supply the country with gas for heating buildings, generating electricity and powering vehicles for up to a hundred years.

“So energy companies are clamoring to drill. And they are getting rare support from their usual sparring partners. Environmentalists say using natural gas will help slow climate change because it burns more cleanly than coal and oil. Lawmakers hail the gas as a source of jobs. They also see it as a way to wean the United States from its dependency on other countries for oil.”
