Executive Summary
- As artificial intelligence (AI) workloads are driving the demand for compute, Data Centres are under pressure to keep up with AI’s energy appetite.
- Operators are investing in technologies such as AI-powered management to reduce waste and cut emissions.
- Data Centres in the UK, alongside government support and industry collaboration, are attempting to strike a balance with AI’s increasing demand for energy
Artificial intelligence is changing the game for data centres across the world, from being used in internet searches, making daily life a bit easier, to assisting with more complex tasks. With this comes a huge surge in energy demand, which data centres are currently struggling to keep up with.
Not only is there a need for bigger servers that can cope with processing large amounts of data, but there is also an urgent call to implement efficient cooling solutions in data centres to help avoid overheating.
Data Centre Space Set to Nearly Double
According to the United Kingdom Data Centre Landscape 2025, data centre space and power are set to nearly double; its research uncovered 50 project announcements from 30 companies. And with this explosion of growth, the UK government has turned its attention to attract more investment in the growth of data centres; firstly, by declaring them ‘critical national infrastructure’ and secondly, by pledging to reform laws so it’s easier to build new centres.
However, this comes with concerns over energy and water consumption: it has been disclosed that Britain’s data centres use close to ten billion litres of potable water each year, which raises concerns of depleting local water supplies. In response, larger companies with data centres have pledged to be water positive by 2030, meaning they return more water to the environment than they consume.
With data centres being largely responsible for a significant share of energy consumption and the pressure to reduce carbon emissions increasing and with 2050 looming closer and closer, there has been a focus on adopting renewable energy, liquid cooling systems and energy-efficient designs, with the number of ‘green’ data centres on the rise.
Operators are turning to a long-term commitment to greener, more sustainable infrastructure, with heat waste recovery and carbon-neutral certifications, but the question is whether these future green data centres can still cope with the demand for more processing power.
Liquid and Hybrid Cooling Solutions
With more power comes more heat, and as we’ve seen already this year, operators have turned to liquid cooling, immersion cooling and hybrid cooling solutions to take the burden off traditional air cooling, which has struggled immensely to keep up with demand. We will be seeing more of this as 2026 begins and beyond, since these technologies have been proven to improve energy efficiency and ensure high-density data centres are more reliable.
This year has seen more AI-driven monitoring and maintenance, which is only set to increase going into 2026 because this has helped facilities teams optimise cooling systems, reduce downtime due to machine learning, and being able to anticipate possible hardware failures – all while cutting operational costs and achieving a higher efficiency with these tasks.
As 2025 draws to a close, the data centre industry and the rapid growth of artificial intelligence heads to a pivotal point in its production as they’re not only defined by innovation but also environmental responsibility. Whilst major strides have been taken to adopt more efficient, sustainable, smarter and resilient operations, will it be enough to ensure the future of data centres is green, innovative and successful long-term?
