Yes, so it's puzzling that the small windmills (necessarily designed for low wind speeds) cost less per peak watt. You'd think getting more power per square meter higher up would reduce the cost per peak watt. Wind speeds are more consistent up there, too. The wildlife concerns are completely specious. The main reason you don't use them in the UK are that the wrong sort of people have political power.
