Sir, – I read with interest Joe Willis’ article (D&S, Nov 13) regarding wind turbines.

As somebody who has promoted wind farms in your paper, it might come as a surprise that I have sympathy with the view that wind farm developments in areas of the North- East have reached saturation point.

While a two kilometre standoff might work in sparsely populated Scotland, it would be hugely impractical in England. I suspect that were this approach adopted, it would leave only areas of outstanding natural beauty and national parks within which developments would be more than two kilometre from a dwelling.

While other parts of the country need to catch up with the wind farm developments in the North-East, I believe that there are emerging technologies which can take up the mantle.

An example of this would be the anaerobic digestion of waste products which can be used to produce both methane and an end substrate which can be used as a fertiliser. I believe it is important that the region continues to contribute towards the move to sustainable energy production and we should embrace these new technologies as part of a suite of measures adopted in this forward- thinking region.
