Lord Hamilton of Epsom (Con)

My Lords, I first apologise to the House. On the first day in Committee, I extolled the virtues of small modular reactors and said that Rolls-Royce were in a very good position to supply these, because I knew about what they had done on nuclear powered submarines. I then remembered afterwards that I am a shareholder of Rolls-Royce, although not a big enough one to bother the Registrar of Lords’ Interests. I hope that I can now apologise unequivocally to the House that I did not mention this earlier, and that noble Lords will forgive me for not having raised it at the time. I will pick up the remarks of the noble Baroness, Lady Boycott, who said how popular net zero was. I would slightly caveat that, because at the end of the day, the whole concept of net zero is extremely popular until people have to start paying for it. It was certainly a big problem when it became apparent that people were going to have to pay £15,000 for a heat exchanger to replace their gas boilers. I know that this proposal has now been withdrawn, but that was just an example of the problems caused by careering very fast towards a very near date of net zero, because the bills start rising all the more markedly. One could argue that people are already paying some of the highest prices in the G7 for energy, and that is largely to do with our drive towards net zero, which has not produced cheaper energy now. We just have to hope that it does in the future, but there is no evidence of that actually happening, and I am not sure there is much in this Bill, either, to encourage one that we are going to see a great era of cheap energy. It is quite interesting that the newspapers today said that we had reached 70% of energy being produced by renewable sources—wind, solar and so forth. What they did not mention was that the week earlier, we had gone through a period when the whole country was covered in cloud and there was no wind whatsoever, so we had a combination of neither solar panels nor wind turbines working. At that stage, 70% of our energy was coming from natural gas. It veers from one extreme to another. The problem with most forms of renewable energy is that they do not work all the time. If they did, it might be possible to get the price down to something slightly more reasonable. We need to be very wary. The noble Lord, Lord Whitty, raised the problem of training enough people to carry out all the tasks that we are envisaging. There seem to be a number of things that are checking the process and involve the spending of money of one sort or another. I am far from sure that we are going to see all this forthcoming in the timescale to hit these very near targets for when we want to reach net zero in this country. We must be wary of being too optimistic that somehow GB Energy is going to solve all these problems. I do not think there is any evidence whatsoever that it will do so.
