The point about fracking stands though, right? Isn't the argument that we may have to cause some environmental damage in the name of plentiful, cheap energy? Then that energy gets harvested and, guess what, it isn't plentiful or cheap either.
One aspect of fracking that I want to know more about is geothermal: no need for chemicals, renewable, under-explored for now. It could be worst because it’s usually deeper, or it could help a lot. Experts mention there has been progress on earthquakes…
Then again, saying that means oil companies will frack for natural gas, claim it’s for geothermal research and leave the whell untapped when the price goes down.
