Most of those effects are from earlier turbines. For new wind parks, shadows are modelled to ensure that no residential buildings are in the shadow. Often no problem if they're close to farmland, there's usually only one inhabited building in a larger radius.

I completely agree with you.

(It's worth nothing that fracking and coal mining are even worse.)

Yeah, my current apartment is in the path of a small urban one for a little while in the spring and fall when the sun is in the right place. It is surprisingly annoying, but tolerable for me since it is just a short time of day for a short part of the year (and I don't get seizures, important since it seems to flash at seizure-triggering speeds). The big ones look like they are slow enough to avoid triggering seizures but would otherwise be worse, lasting longer each day and for more of the year and would be just as annoying. I never considered this side effect until it happened to me.

If by "constant" you mean "for a short period of time in the morning/evening". A tree waving in the breeze creates the same effect, and people seem to live with that.

A tree in the wind is random, a turbine is not.

edit: I love wind noise, it doesn't mean I also love car alarms because they are also noise.

That sucks. I wonder for how many weeks a year the angle of the sun is such that the shadow hits that house.
