My Lords, does my noble friend agree that there are three elements to energy security? The first is the generation of energy, which is very important; the second is energy efficiency, which is also important, and I was very pleased with what he said about that; but the third is the distribution of energy, which is just as important and just as vulnerable. I declare an interest as the chairman of a resilience advisory company. In the light of constant cyberattacks on National Grid and the recent physical attacks on the Nord Stream pipeline, can my noble friend say a word or two about how we are addressing these vulnerabilities in the distribution of energy?
