The hon. Gentleman is being very generous. Some of us on the Opposition Benches consider energy to be a public good, and therefore if we are talking about the optimal way of funding this public good, it would be via the state. The RAB system that he is talking about is very complex and is actually being backed by the state, not the market. Ultimately, if he wants to bring the costs down and make the system more cost-effective and to be optimal—that is the term he used—we would have the state funding this area fully, as well as the rest of the energy roll-out that he is talking about.
The final point I will make is that the hon. Gentleman gave some examples about Heathrow and other large-scale projects, but the difference here is that the system that he is advocating will mean that bill payers will foot much of the risk and much of the bill if there is an overspend. The problem is that that proposal is regressive—it is like a poll tax on energy. The far more progressive way to fund things would be through progressive taxation.
