Energy Efficiency

My hon. Friend raises the interesting point of the possible life expectancy of nuclear power plants. I recognise that there is something of a dilemma in respect of old and new nuclear power stations and predictions of extensions, and that there are issues such as core cracking and whether extensions can be safely undertaken. He makes a fair point, however, that some extensions might be undertaken to bridge the gap. The key point, however, is that one of the best ways to ensure our energy supplies are secure over the coming period and that the generation meets the demand is to ensure that there is less demand for energy, and that the energy we do use is used much more efficiently.
