As far as I know (i can ask my repowering Guru), the restrictive special setback law is only in Bayern, and only to prevent most installations. Setback is 10x turbine height, or some 2 km.

I'll let Mothers Against Turbines explain it best:

Fighting Big Wind

I understand there's been positive buildout in Hesse and Baden Würtemberg, so they can't have such restrictive restrictions. In NRW, the coal lobby has put in place some minor restrictions, but they have no wind anyway. The rest of 'Schland?  Wind is saving the poor lands asses.

But your Senator is simply very wrong about amurka; with some small exceptions in "densely" populated rural areas. And remember, some restrictions are to prevent upwind projects from stealing too much wind from downwind projects/landowners.

Along with Elvis, rational discussion about energy has long left the building.
