Energy Efficiency

I thank the hon. Lady for her comments, and they are good comments, but we are talking about energy efficiency. Nuclear power is very efficient; it has a low carbon footprint. One subject that has not been addressed is how we in this country use energy. I use card meters in my domestic home. When I bought my house, an old gentleman had lived in it beforehand, and he used card meters so I carried on using them. When my family was growing up, I was one of those dads who was always saying, "Switch the lights off." Using card meters started to make us change our habits and how we used energy in our home. The Government might want to consider that. Perhaps we could top up through the internet as we might with a T-Mobile phone—excuse me for unintentionally plugging a particular company. We might usefully consider how we obtain our energy.
