Blades fail all the time... double facepalm.
Storms have wreaked havoc on many a windmill, that factors into their average lifespan as well.
Solar power is completely viable almost anywhere, not just in equatorial regions and deserts. Germany makes a huge amount of power with it, and their climate is not sunny at all (look at their latitude on a globe).
Solar capacity factor in Germany is on average only about 10%. Where they really struggle is in winter months, when their power usage is actually higher, but solar is almost non-existent on many days. "viable" is a subjective term, but I wouldn't agree it makes a lot of sense in Germany. Wind is much more productive for them.
You are some decades back with your "knowledge".
Modern windmills last minimum 30 years
You must have been sleeping when they replaced the generators. Just because the same base is used, doesn't mean they were not replaced.
I am not an expert but I listen to experts. Do you not believe in science, engineering, maths?
You may not be listening to the right experts then, because nothing you stated is a problem that can't be managed.
Does it matter if the drone operator was in the wrong? That does not give the hillbilly permission to shoot it. How about the next time his pickup truck exceeds the speed limit or parks illegally, we set it on fire. Is that OK?
If he is remotely operating a large vehicle in such a dangerous fashion on your property, you might be we within your rights to do so.
