My hon. Friend has already made a powerful case for investment in geothermal. In many constituencies, we have old mine workings and we have some pockets with natural currents of geothermal—Dr Whitehead has worked hard on that in the past. We do have some opportunities to extract relatively warm water and to use it for district heating. Indeed, one of the announcements I made today was about how we are going to bring forward some of the competitions to improve the way we collect waste heat and potentially reuse it. The projects in hon. Friend’s constituency are interesting, and I am sure he will continue to make strong representations about them.
