Good news is developing on the natural gas price front, at least for commodity bulls, as a number of signs suggest that the worst could finally be over for the fuel.

Over the past four years, while silver, corn and other commodities have been on a tear, natural gas has headed south.

The current price near $2.89 (U.S.) per million British thermal units, a measure of the gas’s energy content, is less than a third of the $8.90 that prevailed as recently as 2008. In April, during a panicky lurch downward, prices cratered to less than $2.
