The image on the left shows an oil storage tank. Everything looks normal. But, an infrared view of the same tank taken at the same time, shows the tank is leaking methane. This is the sort of thing that drove the original conservationists batty -- the unnecessary and unproductive waste of valuable resources. Leaks like this -- from wells, storage tanks, and pipelines -- are commonplace and few companies do anything about them despite the fact that the EPA has evidence showing such fixes to be cost effective.

Given that nobody is seriously monitoring this, it is hard to get a real estimate of the problem. However, the EPA estimates a total of about 3 trillion cubic feet. This amount has the warming power of emissions from over half the coal plants in the United States. As people have begun to pay attention, government scientists and industry officials have come to the conclusion that the real figure is almost certainly higher.
