I am very grateful. I apologise to my right hon. Friend the Member for Hitchin and Harpenden (Mr Lilley), who is far more senior than I am.
The hon. Gentleman talks of how cheap onshore wind is as a renewable. Does he not accept that it must be backed up by fossil fuels, which are not so cheap? If the full system cost of onshore wind is taken into consideration, it is one of the least affordable renewable technologies that we have.
