Business of the House

I thank my hon. Friend for raising that important point. She will know that suppliers have to demonstrate to the regulator that they meet sustainability criteria, and there is a process by which the Treasury will arrive at what carve-outs it will do for particular sectors. We have been right to do that for emerging technologies, which cannot currently compete on cost. There is tidal power, for example. Space solar power is another example that we will no doubt look at in the future. She is right to raise the issue of getting value for money for British taxpayers.
