Personally I think they are quite cool - something hypotic \ calming about them.
It's not like digging a quarry for coal or having a huge oil refinery - if they are no longer wanted - take them down and you are left with a concrete foundation, which coudl be left, view unchanged - goes for onshore ones too.
It seems sensibe to produce the energy you want - generate electric and keep it as so, unlike gas \ coal for electric generation.
But hey - what do I know!
