Get away from your keyboard and go and look at a large wind farm. I drove past one at sacramento I think it was. About 10 kms long (thats about 9 times the size of this hole) and the whole mountain range had been sprayed off with herbicide, not a blade of grass to be seen. The erosion down the runoff areas was horrendous. It It looked like what would be left after an apocalypse. Im guessing all those mills would be in land fill by now. And by the way where do you think that the materials came from to build such a disaster? Yep........ out of a hole like the one that you have just posted. Emotional clap trap.
