It seems gusty wind is often the issue. If its constant they can be adjusted

of the blades to be adjusted than it does for the wind to change so after a
certain point they just put them into the safest config and stop them.

I often wonder if a huge array of smaller more responsive devices might work
better, after all across the span of on of those giants the air currents
could be vastly different, putting a strain on the mountings.

well no. the smaller ones would be vastly more expensive.

Anyway the issue is the old Irishism: If you want to generate reliable
electricity don't start with wind turbines.
