After using fracking technology for over 60 yeas on 100,000 wells a year there is no evidence that fracking technology contaminates water wells according to the EPA. So why all the fuss? After all natural gas is a relatively clean and cheap fuel, and the use of fracking has massively increased Americas energy supply by 250 - 500 years, with more yet to be discovered.
Reason TV has been looking into the issue and has produced a video, but the real bottom line (my emphasis added):
The problem with fracking isn’t that it’s particularly new or dangerous. The methodology has been in use for decades, and it is as safe as other drilling processes. The real problem is that it could produce relatively cheap hydrocarbon energy for a very long time, and that’s what has environmentalists worried.
Why are the environmentalist worried? Because it competes with their wind and solar renewable fantasy. Cheap low carbon natural gas will makes these renewables non-competitive, while creating more real "brown"jobs than all the mythical "green" jobs combined. So, the envirnmentalist strategy is to eliminate or constrain the use of the very technology that makes this cheap low carbon energy avilable to American consumers. Tell the environmentalist to frack off, while consumers frack on.
