There’s a good article on the BBC website today from environmental analyst Roger Harrabin on some of the pros and cons of obtaining natural gas from shale rock deep underground. Gas bound within shale is more tightly contained than that within other types of more porous rock, and until recently it’s been commercially unfeasible to extract that gas. Now that “fracking” has solved the technological hurdles associated with recovering that gas, shale is increasingly being tapped to help as a domestic energy source.
While recovering vast stores of gas seems like a good thing, horror stories of the dangers associated with fracking continue to mount. Look for an EPA opinion on this practice in the near future . . .
