In reply to Richard Baynes:
I also think that, as far as any development goes, wind turbines (particularly single turbines) have a relatively low level of long term impact on the surrounding area. In cases where there is already some kind of access track to the location, and grid connection is not overly laborious, should the turbine ever be removed, there would be little visible impact on the landscape (likely just a relatively small area of concrete or similar foundations).
As the life-time of most turbines is in the region of 20 years, at which point they are required (by the planning conditions) to be removed or replaced, I don't feel single turbines have the same long term scarring affect to a landscape as other industrial (or even residential etc.) developments.
This isn't to say that this necessarily mitigates the visual impact for those 20 years, but I think that, as said above, some perspective on the overall impact on the region should be considered.
In fact, in a community development such as this, (depending on their contractual obligations) there may be no reason why the turbine could not be removed after the 10 year payback time envisaged, should it be deemed detrimental to the local environment/tourist trade.
