"Gas can migrate ... from poor drilling into people's private water wells. ... We have had gas move from poorly done gas drilling through the ground and reach people's water wells. So there is a need for oversight ... gas does have some impacts. It is not perfectly clean. But compared to coal and oil, which are more dirty fossil fuels, natural gas can be produced and consumed in a manner that is cleaner than coal."
Filmmaker Josh Fox concedes that the states concluded that the fire wasn't caused by fracking, but he says the government regulators collude with industry, or don't use good science. His movie portrays Hanger as an indifferent bureaucrat. Hanger says the movie is just inaccurate. "Josh Fox has a mission. ... He is trying to shut down the gas -- drilling industry."
Frankly, I'm skeptical of all of them: lefty moviemakers who smear companies, companies with economic interests at stake and the regulators, who are often cozy with industry and lack essential knowledge. The surest environmental protectors are property rights -- and courts that assign liability to polluters.
But hydraulic fracturing is a wonderful thing. It's not new. Companies have done it for 60 years, but now they've found ways to get even more gas out of the ground. That's the reason gas is getting cheaper and panicky politicians no longer rant about America "running out of fuel."
Natural gas is not risk-free, but no energy source is. Perfect is not one of the choices.
