Waterless fracking
There are already several processes that allow fracking without the use of water. This only reduces some of the hazards of fracking and it doesn't add to the limited affect that fracking will have on the overall longevity of the fossil energy paradigm. It's just one of the last desperate acts of dependent consumption of a finite declining resource. Unfortunately, we are only in the early stages of this phase and we'll see quite a bit more before we make the transition (apparently with minimum preparation) to a more sustainable energy source.
