Energy Efficiency

If the hon. Gentleman could hold on for a second and let me make a bit of progress, I will be delighted to give way. I have not even begun the argument yet—I have only announced the subject matter—and he is already having a pop. Let me take hon. Members back to last March and how people felt on the day before the clocks changed and on the day after. There is a natural feel-good factor for people when that lighter evening comes in, but it goes beyond that: there is also a financial benefit and an effect on the environment. Electricity prices would go down because we would be naturally aligning the time spent at our workplace during the day with the time when the sun, the last form of free energy, is in the sky. There is a natural recognition of how we could better use that time. When the sun is in the sky and we are all in bed, that is wasted energy. Before I make further progress, I will give way to the hon. Member for Dunfermline and West Fife (Thomas Docherty), as I promised.
