Natural Gas in Pennsylvania

Pennsylvania's Natural Gas reserves alone could power the US for 10-15 years, according to this article on the Chesapeake Bay Foundation's website. Like any kind of mining, extraction can be environmentally difficult, though it sounds like appropriate care can mitigate a lot of the problems. However nasty it might be, I'd much rather have it going on in this country where it can be carefully monitored instead of leaving it to be extracted in the Middle East or other places and then have it traveling here in tankers.
