I thank my noble friend for his intervention. However, I would err on the side of caution: if we do not look at this in greater detail, we might inadvertently restrict ourselves from looking at other technologies that may come on stream by putting into legislation things that are going to be restricted because we have mandated it in the legislation, when we are already doing many things that meet what noble Lords are asking for. It would probably be much more constructive to be able to say that this would not be necessary, given that we are already doing it. However, as with all things, I am very happy to talk to noble Lords outside the Room to see where they feel that I am not fulfilling this condition.
I would like to respond to the noble Lord, Lord Cameron, about new build and RHI. I do not have the details for that here, but perhaps he would allow me to write to him and send copies to other Members of the Committee.
I hope that the noble Lord, Lord Whitty, will withdraw his amendment.
