A Miracle In the Marcellus Shale?

by

It’s fair to say that lot of people, from shale gas operators to Pennsylvania state revenue collectors, see $$$ every time they think about the Marcellus shale. Only recalcitrant environmentalists worried about polluted drinking water do not salivate at the prospect that many years of U.S. gas supply will come from the Marcellus. Today I will not deal with the environmental issues. Instead, I want to examine the view that resources in the Marcellus are a big part of the shale gas cure-all for America’s energy problems.

Forever and a day

by

Talk with many green technology advocates and you might get the impression that we have forever and a day to make the transition from an unsustainable society to a sustainable one. But the most critical question is how much time we have to make the transition. A fully equipped hospital with on-duty surgeons and staff may be the ideal technology for a critically injured patient. But they mean little to such a patient if we are in the position of having to build the hospital and train the surgeons and staff before administering treatment.
