Fracking produces natural gas which is about as green of energy as you can get.If we were to pump money into building the infrastructure to utilize all the natural gas the fracking wells burn off, it would be an economic boon. It is also the way to get us out of OPEC and away from dependence on the petro dollar. Fracking enables the US to be energy independent. It is breaking through the earth to hit shale. The jury is still out IMO on environmental impact. IMO any sort of mining is undesirable. But we need oil.
