My Lords, first, I declare my interest as a director of Aldustria Ltd, which is an energy storage company. I thought the noble Lord, Lord Rooker—who I have huge regard for—was back into Corbynism there for just a moment. I knew someone who worked for the Central Electricity Generating Board. It was a great time in history.
The Minister mentioned both value for money and zero carbon, and I want to come back to both. One of the basic things about zero carbon is the circular economy, and one of the first questions on the decision tree of circular economy is whether you need something or not. I will go down that route in a minute. I have always been favourable to nuclear power but, over the last decade, facts have changed. That is why I am sceptical about the need for this type of nuclear development altogether. Let me say why.
First, we still have not solved the nuclear waste issue—and it is a real issue. Conversations with local authorities and communities are going on throughout the UK about finding a way forward but, even if we do, those facilities will not be ready for many decades, as we have seen from previous experience in Finland. Secondly, I come to the area of baseload because this is, if you like, a 1990s argument. One thing about nuclear power—particularly with Hinkley C, which I have visited, and Sizewell C—is that, for it to be effective, it needs to operate consistently: it does not go up and it does not go down. If we have large renewables in this country, nuclear must go up and down from hour to hour, day to day, week to week. It is not a technology suited to that. It becomes inefficient. It is inefficient not only operationally but in terms of what the Bill is trying to do, which is minimise capital costs. I know from my experience in industry that, when you have capital, you work it day and night as long as you can: you sweat the assets. With a large renewable input into our electricity system, that becomes not possible with nuclear power after a certain threshold.
Also, you come to costs, and this is where facts come in: the cost curve for nuclear has gone up while the cost curve on renewables has come down significantly, as we know. I congratulate the Government on part of their work in making sure that is the case. In terms of value for money, which was the Minister’s caveat on this nuclear project, it seems to clearly fail. The trend is going that way, but we have the largest energy cost crisis that we have had in many years at the moment, and we are told that it is not going away any time soon. Yet the Bill actually adds costs to consumers, when we have a cost-of-living crisis—fuelled by energy—that is more of a problem than it has been for some time. If I was an adviser to the Government—which I never have been or will be—and I wanted to use nuclear power, I would probably go down the Korean
route: you build a fleet of 20, you get your economies of scale and you finance it through the public purse, which has minimum interest cost. What do you have? You have a much cheaper capital cost, zero carbon and greater efficiency. The Government are not going down that route, but that has been shown as probably the only way that you can make nuclear power successful in the modern world.
There is an alternative—and, strangely enough, it is not renewables. It is that boring thing called energy efficiency. The Minister shakes his head, but every government publication with comparisons says that energy efficiency shows the highest return in terms of capital investment that there is. For the £20 billion that this will cost—probably more at the end of the day—it is my rough calculation that you can retrofit 2 million to 3 million homes; those would be some of the worst ones to bring up. This is important for social fuel poverty but also means that energy costs for consumers go down—whereas the Bill makes them go up. Page 55 of the 2019 Conservative manifesto says:
“We will help lower energy bills”—
somewhat ironic—
“by investing £9.2 billion in the energy efficiency of homes, schools and hospitals.”
Fantastic, but it is not enough. Here, twice that could be put towards it. I ask the Minister: how much of that £9.2 billion has already been spent, half way through the Parliament?
