Sir, So the Pendine wind farm is to be more than doubled in size. Carmarthenshire County Council say this is acceptable. But when the original scheme was proposed some years ago, the county council opposed it on environmental grounds! They are doing more than they need to under the terms of TAN 8, the guidance document from the Welsh Assembly Government. Where will it end? What those of us who have been opposing turbines for many years have forecast is now coming to pass. Before long there won't be a viewpoint in the 'Garden of Wales' from which you will not see these machines, which will be making a lot of money for a few developers and landowners while producing comparatively little electricity and only for a third of the time most. And as for helping to combat climate change, the latest research conducted by Jesse Ausubel, Professor of Environmental Science and Director of the Human Environment Programme at Rockefeller University in New York, indicates that huge swathes of countryside would need to be industrialised to produce really significant reductions in CO2 emissions (The Guardian, 25.07.07). Is this really what we want so that we can carry on behaving as if there were no tomorrow?
