Here we go again. In a scene that is being repeated continually in many corners of the world, a windfarm developer - in this case, unusually, Vestas - has had its application thrown out by a combination of planners and local politicians.

Vestas makes wind turbines and has a blade manufacturing unit on the Isle of Wight. And yet, the company which employs 600 on this tiny island is not able to site a wind turbine there.

Windpower is increasing worldwide, but far, far more windpower projects never get off the drawing board because of planning objections. That's why I think there's a strong case for the industry concentrating on sparsely populated poor countries and exporting it through high voltage transmission cables to richer countries.
