Energy Efficiency

On that I stop agreeing with the hon. Lady. We are not talking about a technology that may or may not work. We know that it can work; it is a matter of harnessing it. Experiments have already been done. To park the issue, or put it on the back burner—that is probably the wrong phrase—would be wrong. If we can harness the technology we can roll it out, not only in Britain but in other countries, particularly developing countries that are thinking of using nuclear fission. We could say to Iran, "Here is nuclear fusion." An atomic bomb cannot be made out of a nuclear fusion reactor. This therefore makes sense in the long term, and generations will thank us for it. Given the position we are in, I am afraid that we cannot survive over the next 20 years without investing, reluctantly though it will be, in nuclear power. I think that there is agreement on that in all parts of the House. Let me spend a few moments explaining why nuclear fusion is so important and useful. It is the fusion of hydrogen atoms to form helium, and an awful lot of energy. It is a safe process whereby there are no nasty by-products. Of course, hydrogen is found in water, so fusion power is a potentially limitless source of energy. In fact, it is recognised that in 100 years' time nuclear fission will be in the past, and everything will be powered by nuclear fusion. That may sound scatty, too advanced or too romantic, but it is the case. However, I am afraid that we will slow down that harnessing of power unless we are able to ensure that we join with other countries to guarantee that money is not wasted or taken away to be spent on other important related products, as the hon. Member for Brighton, Pavilion (Caroline Lucas) passionately said. The main focus of my speech is not nuclear fusion or carbon capture and storage, but the subject of my intervention at the beginning of the debate. It is about a very simple way of reducing carbon emissions, saving the Government money, and creating a feel-good factor—that is, moving our clocks one hour forward.
