Energy Grid Resilience

Debate between Lord Hunt of Kings Heath and Viscount Stansgate

Tuesday 6th May 2025 Lords Chamber

[Lord Hunt of Kings Heath (Lab)]

My Lords, as I think I have already said, the security of our energy system is clearly critical. I take the point the noble and right reverend Lord raised about cybersecurity. Noble Lords will have seen the devastating impact that this has had on retailers in the last few weeks. We work with the National Cyber Security Centre. We are very exercised about this. I can assure the noble and right reverend Lord that we are not at all complacent.

[Viscount Stansgate (Lab)]

My noble friend the Minister has already referred to the fact that the system operator is introducing innovative new approaches. Might that involve the application of AI to managing the grid? Looking further ahead, and in the light of the report from your Lordships’ Science and Technology Committee on long-duration energy storage, could the Minister indicate whether or when the Government might take the type of strategic interest in long-duration energy storage that we will need?

[Lord Hunt of Kings Heath (Lab)]

My noble friend is right about AI; that was one of the main points raised in the Tony Blair Institute report, which was raised earlier. We are giving long-duration energy storage a great deal of attention.

Internet Activity: Energy Use

Debate between Lord Hunt of Kings Heath and Viscount Stansgate

Monday 27th January 2025 Lords Chamber

[The Minister of State, Department for Energy Security and Net Zero (Lord Hunt of Kings Heath) (Lab)]

My Lords, the National Energy System Operator has estimated that data centres consume around 2.5% of the UK’s electricity. The UK is not a major centre for cryptocurrency mining. We estimate the share of power consumed in the UK for this purpose to be negligible.

[Viscount Stansgate (Lab)]

I thank my noble friend for that Answer. I do not know whether the House quite realises the staggering quantities of energy involved in normal internet activity and, in particular, in crypto mining. It has been estimated that the usage is approximately the same as that of a mid-sized European country, such as the Netherlands or Denmark. How much of this activity is based in the UK? Who is doing it and where? Does my noble friend agree that it has an adverse impact on carbon emissions and brings with it electronic waste? Will he agree to undertake an assessment of the potential adverse effects on carbon emissions of internet activity and, in particular, of crypto mining, so that we can have an honest discussion about the future and the effect of this on our climate change objectives?

[Lord Hunt of Kings Heath (Lab)]

My noble friend is right to raise this important question. I should say that the Government keep this under review. In fact, we reckon that only 0.2% of global crypto mining takes place in the UK. The International Energy Agency has estimated that, in 2022, 2% of total global energy demand came from data centres, cryptocurrencies and AI. It expects that to double by 2026. However, it makes the point that it expects that doubling to be met by an increase in clean energy sources. The lesson here for us is that we need to power on with our aim to get to clean power by 2030.
