Grantham on Natural Gas

From the latest GMO quarterly letter:

"At the opposite end of the resource spectrum to record-priced Iowa farmland is natural gas. Natural gas is, for most purposes like home heating and electric utility plants, a better and cleaner fuel than oil or coal, but is for technical reasons in distress: there have been several recent decades in which the BTU equivalent price for natural gas did, at least for a second, reach parity with oil. But now it is at just 14% of BTU equivalency, the lowest in almost 50 years. Everyone who has a brain should be thinking of how to make money on this in the longer term."
