Well, I was the person asking the questions, and I know that the Library notes are very thick. One survey, on buildings—particularly office buildings—was not conclusive, but on domestic homes and electricity peak demands, the evidence was to the contrary, which is why I am arguing that we need to consider gas consumption as well as electricity demands. We would then get a much clearer picture to show the benefits of energy savings.
In responding to my right hon. Friend the Member for Gordon (Malcolm Bruce), surely the hon. Gentleman might have pointed out that the Bill proposes more detailed research on such matters—research that I am convinced will lead to the sort of evidence to which he is referring.
