Wind turbines, plenty of them seen from here. Started counting one clear day, got to 80
and rather lost interest. They've certainly had a windy couple of years. The question is
what is their working life?

Planning applications usually give a working life of 20 years and some
are now already more than half-way through this. A more important
point is what happens when the 20 years is up? Will they be left as rusting
monuments or replaced by even larger turbines?
