In this section, we focus on the environmental impacts of drilling for natural gas in the Marcellus Shale formations using the fracking or fracturing method (some background info is given on the Marcellus Shale page). Thoughts about use of the resultant natural gas itself can be found in the Energy section in the piece by Dennis Lieb: "The Drive-in Utopia is Closed". The … [Read more...] about Impacts of drilling in Marcellus Shale
Most experts now agree that 'Hubbert's Peak' — the point at which world oil production starts to decline—has either already passed or will occur within the next year or so. Some of the world's largest fields, in Saudi Arabia, Mexico, and Kuwait, have already peaked. (U.S. production peaked 30 years ago.) Even as oil and gas production are declining, consumption continues at … [Read more...] about What is ‘Peak Oil’?

The technique is basically to blast the top of the mountain and push the rubble off into the valleys to expose the coal seam, which is then trucked away. Then another round of blasting takes them down to the next layer, and so on. The practice uses far fewer miners than … [Read more...] about MountainTop Removal mining (MTR)
