I wanted to answer the hon. Gentleman’s question about evidence of an effect on house prices. A study in Cornwall analysed 201 sales transactions of
houses within half a mile of a 16-turbine wind farm and found a noticeable effect. It said that both the noise and the flicker from turbine blades could blight certain properties, and that the view of the countryside enjoyed by the occupier had some value, which might be affected by a wind farm. The Royal Institution of Chartered Surveyors argues that there is evidence suggesting an effect on house prices. The matter is not evidence-free. There is growing evidence of an effect, certainly while there is uncertainty about whether a development will be built.
