Yea they massively change the views in the local area. How ugly they are is probably the top complaint in the UK about them
As unlike a lot of the American commenters here saying we don’t have huge sprawling areas of nothing (Except Scottish highlands) just waiting to be filled with something. So for rural voters that live in the countryside for the views damaging/changing the views is unsurprisingly not that popular.
In 2015 because of lots of local opposition the government made it easier to object to wind farms in your areas but people have since said that those rules make it too easy to get planning permission rejected.
Recent polls seem to suggest people care less now though lack of increase in planning permissions for onshore wind seem to show that people like it more in theory than when the wind turbines will be built in their view.
