The taller the wind turbine, the harder they fall. And they sure are falling.
Wind turbine failures are on the uptick, from Oklahoma to Sweden and Colorado to Germany, with all three of the major manufacturers admitting that the race to create bigger turbines has invited manufacturing issues, according to a report from Bloomberg.

If it's happening, then it should be happening. Obviously there are some engineering shortcomings somewhere in the mix. That's the nature of reality (where leftists and other types fear to tread).
I saw miles and miles of these things on my ride down to Peoria IL from Chicago. My grandson says they’re everywhere in central Illinois.
IMH (mech eng) opinion, they underestimated the wind and resulting bending moment where the base of the wind turbine entered the ground.
If you have not seen “engineering disasters” about the Seattle Tacoma narrows bridge, there a videos here showing it flop around like a noodle and fall because the engineers miscalculated or neglected wind loads.

“..It’s gravity.....”
Gravity??!!! Surely you jest.
That old concept of “gravity” was brought about one of those bad, old, racist white men....I believe even his name reeks or “racism”: Sir Isaac Newton. “Sir” my black arse!!! Therefore, the concept of “gravity” is racist and must be rejected at all costs and considered a false concept around this flat world. (BTW, it ain’t round..that was another old racist white guy).
So why are these things toppling over? It’s because of Trump!!! Just ask the MadMaxiePad...it will tell ya exactly why it’s happening.
It's obvious that people have a fundamental misunderstanding of wind turbines. Too many are under the mistaken impression that the turbines are erected to generate 'electricity'. In reality, they are built to produce 'felicity', and they do indeed make environmentalists blissfully happy, whether the turbines are upright and functioning or laying in pieces on the ground...

Its caused by Rigid Resonance, my personal nomenclature. The base of the tower is set in concrete and the rotor head is not allowed to oscillate/flex while rotating, setting up a rigid fixture. Something like a flexible gimble head or shaft/gear box set on large rubber donuts to allow some flexing between the prop head and the tower will solve the problem. Admiral John F’ing Kerry knows all about that.
Correct. They should be being dismantled, not falling over willy nilly. They are corrupting my “view shed”. Remember when someone could stop a project by saying that?
> without special inspection of footings the contractors will cheat like crazy <
You sure are right about that. A guy I know (now retired) was a building inspector. Well, one day he made a surprise inspection at a hotel site. If I recall correctly, the specs for one section of concrete called for rebars 12 inches apart. The workers were laying them 18 inches apart. Just to save a few bucks.
“It is by faith alone that the wind turbine towers are able to stand.”
Yes, and in order to make sure that the towers don’t fall, all good liberals should extend their arms and spin in a circle for at least 3 minutes a day in order to transfer their spiritual energy to the turbines and help stabilize them. Preferably while blindfolded and standing next to a busy intersection.
Lay them down on the ground and they won’t fall. Problem solved.
From those pictures, it doesn’t look like the failure point is the connection between the concrete footings and the steel tube. The tube has deformed above the ground a good ways and failed like an empty pop can squeezed in the middle.
I had a girlfriend like that in college.
This is happening because they’re a poorly designed, bad idea, ineptly executed.
Oh, and a waste of time, money and resources.
Damned things are all over Germany, ruining the scenery. I didn’t realize how big they were until I stood next to one. In the past three years I’ve seen one fall, one burn, and one hanging lopsided missing a blade. I assume the laws of physics play a part in tearing these beasties apart.
“If you push something hard enough it will fall over.”
Do the other towers feel bad when one of their compatriots topples?
Judging by those photographs I didn’t see any failures in footings, I saw failure in hollow tubes disguised as structural towers.
