What if a kindergarten or refugee home is built next to you? After all, you buy the plot of land you build on, but not the surroundings.
There are often local protests there as well. It's just usually smaller in terms of the area affected. You can see a wind turbine from much farther away, so it feels like more people get involved, even if they themselves aren’t direct neighbors. (See, for example, arguments like "But it ruins our landscape view!!") Otherwise, this is just a topic at many different places in Germany at the same time, so on the one hand it is simply more present and on the other hand it is probably easier to find arguments for it than for why the new kindergarten in Hintertupfingen in the district of Kleinhausen locally worsens the traffic situation too much and causes noise disturbance for the 2 nearby residents.
Isn’t that its own risk with every investment?
Sure, but that’s always easy to say when you’re not personally affected at the moment. Basically, it’s often actually the case that there is probably an equally good if not better suitable location somewhere else (often even nearby). And when you’re affected yourself, you take a closer look. "Look, it would be much better over there, why here?! That’s just really stupid!" And the answers to that are often not exactly very satisfying for the residents either. (The one wind turbine here was built, among other things, through a lot of initiative by the farmer who owned the land. The answer to "why here and not there" in that case is therefore "because someone owned it who was willing to push it forward," and far from "because it was the best location for it"). Basically, though, I agree with you that there is always a certain risk that something in the surroundings will change.
