Our Amazing Disappearing Mountains

Yep.

I agree with the purpose of this video and deplore the destruction of appalachia, but on a pedantic note, wasn't that a nuclear power plant at the end there? or is that sort of cooling tower also used for coal?

Cooling towers are used by all sorts of things, where the supply of cooling water is limited (ie mostly inland). Power stations of all sorts can have them and the curved concrete ones shown here are pretty common but not the only type you might see.
In the case of the video, the power station shown _is_ a coal fired one. At the start of the panning shot and to the left you can fairly clearly see the coal stockpile and conveyors.

Also agreeing with the sentiments of the video, one thing that annoys me is that when films or photos show "pollution" from the power station or large industrial process there is always a shot of cooling towers with big plumes of white stuff. It's only water vapour (OK so it's arguable there is some heat pollution there, but that's minor in the other environmental impacts). The real pollution, the real mountains in this video, are being expelled invisibly. Up the thin stacks in the background and out into the ash heaps.
