Internet Activity: Energy Use

Lord Holmes of Richmond Excerpts

Monday 27th January 2025 Lords Chamber

[Lord Hunt of Kings Heath (Lab)]

The work of NESO in mapping out how we get to clean power by 2030 is the start of this process, and we will keep those matters within the review. We are working very hard with the network companies and Ofgem to accelerate investment and reform in the grid and in connection. That is a crucial matter in wanting to see an expansion of data centres in the UK where we have a significant advantage and an increasingly important market.

[Lord Holmes of Richmond (Con)]

My Lords, I declare my technology interests as set out in register. Does the Minister agree that, going broader, we need far greater transparency about all the power that it takes to fuel these new technologies—compute power, energy power, and financial and natural resources? Is it time that we reviewed the power usage effectiveness measure, or PUE, for data centres? Is it the case that all these new technologies need to be considered not just in respect of how efficient they are and how effectively they are fuelled but, crucially, that this is done in a sustainable manner?

[Lord Hunt of Kings Heath (Lab)]

My Lords, I certainly accept the challenge from the noble Lord: as we wish to see the encouragement of data centres and the use and development of AI in the UK, clearly we want it to be sustainable. I make the point that, in the first place, newer cryptocurrencies use less energy than the original ones, and, secondly, that data centres are increasingly looking to energy efficiency methods. AI can be used as one way in which to improve our management of energy efficiency.
