The economics are worse than that. You don’t have to post a bond to build these infernal machines. So in 20 years when they are all worn out and the companies are all bankrupt and out of business, they will just stand there producing nothing and blighting the landscape forever. Unless the government comes in and spends a billion dollars to tear them all down and dig up tens of millions of tons of concrete in the ground.
You can’t get away with that with any surface mine. You have to post a huge surety bond before you open the mine. That money is used to reclaim the land when you are done mining. Only wind and solar get away with this crap.
