Those are probably Vestas, They just opened a facility in my town. But on the Coal side, I had this video that is on my Facebook page. A tape of a coal blast to clear rock...Awesome video. My Mother in law works at a coal mine so when we visit and if we make it to the mine, near Gillette WY, we get to see a blast... Impressive.
The reclamation around the mine is impressive too. The area where the coal has already been mined from looks like it is due for mine expansion. It looks untouched. The only indication that there was a mine there are piles of rocks to allow wildlife areas of "self preservation" from predators, raptors and canines. Mostly for small animals. Hell they have even begun to drill through the reclaimed areas to get to oil (much deeper than coal) and it is stable enough to support the wells.
