Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.
Setback is generally handled on the county level.  Sometimes (like in New York State and Washington state) there is a state permit process that is expensive and complicated, but serves as an alternative if a county enacts overly restrictive rules.

There are lot's of places (mostly in Texas) with zero zoning or even permit requirements.  You can just put anything you want wherever you want.  In this cases, you only have to comply with federal laws, like the endangered species act.  

Other places have extremely strict rules with crazy setbacks of 1 mile or more.  In those cases, there generally aren't any wind turbines in operation.  Those big setbacks effectively serve as a ban on utility scale turbines.  You can see the in various counties in New York, Washington, and Wisconsin. (AND Bayern!)  They are generally the result of an active anti-wind community that holds political sway with the county council (OR the local Seehofer.) The objective rationale for such rules are typically infra-sound and "wind turbine syndrome".

Most reasonable locations have setbacks of 1 or maybe 1.1 times fall-down height (Unplanned Rapid Disassembly Event) from roads and power lines and something like 1000 feet or maybe a bit more (1/4 mile is common) to either a non-participating property line or a residence (property line being moe restrictive).  Sound ordinances are all over the board, but range from 35dBA to 45dBA, either measured at a residence or at a property line.  Badly written ordinances have requirements for infra-sound.

There are often rules related to shadow flicker, and also to wake shadow.  Shadow flicker is usually defined by hour/year that a residence has flicker.  It can range from about 3 hours to about 30 hours.  Wind shadow is usually ignored.  Riverside county in CA has what I consider to be one of the better zoning laws, especially regarding wakes (downwind loss of energy). They require a 10 (I think- maybe it's only 5) Rotor Diameter separation from a non-participating land owner in the downwind direction.

In most cases serious restrictions have zero to do with citizen protection and much to do with utility protection.

Thanks. I'm hoping that the senator will reply to tell us where he got the information that "the Americans have just decided to fix setback at 2,000 metres".

He did mention "some German länder" where setback is at 1,500 metres. As far as I've been able to see, that's indeed Bayern. Do you know of any others?

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.
