I won't discuss the common sense and "as slow as they move" comment. I will just share a link that shows how fast they can be moving.Just plane ol common sense tells me, any bird that is so dumb they can't avoid a wind turbine blade, as slow as they move, won't survive long anyway, RIGHT?
From the article link.
"Regular turbines comfortably achieve speeds of 100mph, larger styles with heavier blades, reach speeds of 180mph."
