CHRISTINE Harbottle may be happy to see the whole the countryside covered with wind turbines based on the opinions of a few holiday makers sitting on a beach last summer, but I am not. The 'research'  she recommends is nothing more than a month-long survey, commissioned and paid for by the green energy companies who have a vested interest in the erection of still more turbines. It would be deeply unsatisfactory to use 'evidence' of this anecdotal nature as a guide for making government policy, even at a local level. As I stated in my earlier letter, wind turbines have massively increased, both in size and in number, countrywide over the last six years, yet no further independent and academic research into any negative effects they may have has been done. The Hutton Institute report Ms Harbottle mentions includes virtually no new evidence, it is merely a literature review of existing research, the most recent of which is still the Moffat Report of 2008. The one thing we definitely know about wind turbines is that they have failed to contribute to any meaningful reduction of CO² emissions Europe-wide because we have had to continue to operate the traditional fossil fuel power stations to make up for the unreliable power supply from wind alone. Tourists questioned for that report admitted to being disposed to look more favourably on wind turbines because they were helping save the planet by producing green energy. What would they have said if they had known that this was not the case? We don't know because no-one has asked them. Let us present tourists with all the facts about wind turbines before we rely too much on their opinions to influence planning decisions regarding the erection of even more turbines.   Rebecca Bartleet Latchley Gunnislake
