Energy triage

I found an interesting article on energy triage at http://www.plantservices.com/articles/2006/284.html. However, it's not clear to me when it was posted or if the ideas in it have been applied in practice.

Also in the same area, I found an old article on smokestack (industrial chimneys) with the same slant (http://ecoworld.com/features/1995/12/01/free-market-environmental-protec...)
