I am very much aware of that study and obviously agree with what Professor Styles found. The interesting thing is that, as turbines get larger, amplitude modulation is generated over a slightly larger area. We have gone past the 80-metre stage. My constituency has dozens of wind turbines of 126.5 metres and upwards. That is about the size of the London Eye. When the blades move around and chop the wind, they create amplitude modulation. There is an understanding now that this is happening, so we need a suitable and sensible planning condition to ensure local communities affected by this problem have a way of stopping it happening to them.

This is why I wanted to talk about the application of an amplitude modulation planning condition, such as the one that came forward in 2009 for Den Brook in Devon. That represented a serious risk to the wind
industry, which fought it tooth and nail. A planning condition of this type can add cost and make it more difficult to get turbines through the planning process. People might well decide to campaign even more against a big industrial turbine being placed near them if it has potential health risks.
