Natural Gas Changes the Energy Map

Deep drilling: At Range Resources’ site in Washington County, PA, a specially designed rig is used to drill more than a thousand meters down and gradually turn 90° to follow the gas-rich shale deposit. The rig will drill half a dozen wells at the site. Beside it is a pond holding debris and mud from a well. Credit: Roy Ritchie

From Technology Review:

Vast amounts of the clean-burning fossil fuel have been discovered in shale deposits, setting off a gas rush. But how it will affect our energy use is still uncertain.

The first sign that there's something unusual about the flat black rocks strewn across the shore of Lake Erie comes when Gary Lash smashes two of them together. They break easily and fall into shards that give off the faint odor of hydrocarbons, similar to the smell of kerosene. But for Lash, a geologist and professor at nearby SUNY Fredonia, smashing the rocks is a simple trick designed to catch the attention of a visitor. The black outcroppings that protrude from the nearby bluff onto the narrow beach are what really interest him.
