One comment from that link made me curious.

"They should install wind turbines around the perimeter of the hole and take advantage of it! New form of renewable energy – hole in the ground energy!"

Clearly a form of joke, but im intrigued to know why this won't work. (Or why it could work)

If you are digging really big holes, there are presumably more efficient geothermal schemes.

These typically require large investments to build and suffer from other problems like salt corrosion, whereas putting wind turbines in seems like a very quick win.

Sure, absolutely - but that hole is already there. Is there any way to use it for generating energy somehow?
