Does the Minister agree that the energy crisis is a matter not just of supply but of demand, and that the cheapest bill is the one that does not have to be paid because the energy is not being used? Does he intend to announce today ways of tackling the demand side? We could, for example, ensure that all new buildings are built to net zero standards, and announce a timeline for getting to that point as soon as possible. We could also announce a nationwide, street-by-street insulation programme to tackle the need for energy efficiency; that is the cheapest and quickest way to address the energy crisis. If he is not going to make those announcements today, when will they be made?
