Data Centres: Energy and Water Consumption

Lord Wigley Excerpts

Tuesday 8th July 2025 Lords Chamber

[Lord Vallance of Balham (Lab)]

The AI Energy Council is set up as a joint council between the Secretary of States for DESNZ and for DSIT. The noble Earl is right that, at the moment, around 2.5% of current total energy consumption is in data centres. The total amount of electricity use is due to go up from seven to 62 terawatt hours by 2050. In relation to the overall increase in requirement for electric vehicles and others, that is still about 10% of the total. However, it is a really important issue that the energy council is looking at and it leads to questions about the supply, and work on small module reactors may be part of the solution.

[Lord Wigley (PC)]

My Lords, would the Minister accept that, for both energy and water, there may be significant implications for the devolved Governments in Scotland and Wales, particularly with water needed in north-west England, the Midlands and the Thames area coming from water supplies from Wales? Can he undertake to keep in close touch with the Governments of Wales and Scotland on these matters?

[Lord Vallance of Balham (Lab)]

The AI growth zones can be distributed right the way around the country. There is a very specific plan for each of those proposals, and they must be looked at with local engagement with the relevant authorities. I am sure there will be contact with the devolved Governments as part of that.
