Energy companies have worked hard to promote the idea that natural gas is the fossil fuel of tomorrow, and they have found reliable allies among policy makers in Washington.
“The potential for natural gas is enormous,” President Obama said in a speech this year, having cited it as an issue on which Democrats and Republicans can agree.
The Department of Energy boasts in news releases about helping jump-start the boom in drilling by financing some research that made it possible to tap the gas trapped in shale formations deep underground.
In its annual forecasting reports, the United States Energy Information Administration, a division of the Energy Department, has steadily increased its estimates of domestic supplies of natural gas, and investors and the oil and gas industry have repeated them widely to make their case about a prosperous future.
But not everyone in the Energy Information Administration agrees. In scores of internal e-mails and documents, officials within the Energy Information Administration, or E.I.A., voice skepticism about the shale gas industry.
One official says the shale industry may be “set up for failure.” “It is quite likely that many of these companies will go bankrupt,” a senior adviser to the Energy Information Administration administrator predicts. Several officials echo concerns raised during previous bubbles, in housing and in technology stocks, for example, that ended in a bust.
