They get hot under the collar because the turbines are anti-human scale, they are inefficient, they wreck wildlife, they ruin the landscape (a new one near here, visible for miles around, sits atop the pristine landscape and ancient woodland of Dizzard Cliff), and they are an utter con designed to make already-wealthy farmers/landowners even richer (to the tune of £40-50,000 a year per windmill, better than a teacher's wages, all for taking up a few square metres and costing you nothing). You could cover the whole country with these useless abominations and still make far less green energy savings than a decent nationwide plan to conserve energy. But no, we erect these bloody things willy-nilly and just carry on wasting energy, all with that much clearer a conscience.
