I suppose that if the blade came apart and one of the atoms were to split in the process, it could cause a nuclear chain reaction that would wipe out entire cities. I like to discuss things that could actually happen.
An entire wind generator blade on the ground would occupy about .05 acres. The entire blade won’t fall on crops because the base of each wind generator has an area cleared of foliage, so you can expect about 1/4 of the blade to land there, leaving only .0375 acres impacted by the blade. Further, crops are planted in rows, so only a negligible portion of the crop would be impacted. Depending on the time of the failure, the crop may not be impacted at all.
I have never seen a field cleared because of a wind generator failure. Have you? Have you ever seen a wind generator failure in a field of crops?
There are plenty of legitimate arguments against wind farms without introducing misinformation. Misinformation only harms the legitimate arguments.
This took me ten seconds to find.
