The UK Government is poised to “dismantle” planning regulations under a new AI Bill, which would facilitate the automatic approval of massive data centres nationwide, as reported.
This move could spell disaster for energy security, pose threats to our water resources, and severely hinder any ongoing decarbonisation efforts.
Revelations about these proposed modifications emerged in the same week that both the IMF and the Bank of England cautioned against the potential ramifications of an “AI bubble”.
Growth Claims
The administration is eager to present these new data centres as a catalyst for growth. However, the truth is that any positive outcomes for productivity will be marginal, primarily benefiting their US-based owners rather than local economies.
Job creation will be minimal, and the industry’s economic dynamics suggest that these massive investments will depreciate significantly within just a few years.
Data centres serve as the backbone of the internet, handling the vast amounts of data, from emails to viral videos, that characterize the modern web.
After years of relatively slow growth, the onset of ‘artificial intelligence’, which heavily relies on the analysis of extensive data sets, has dramatically increased their demand. ‘Hyperscale’ data centres, which contain 5,000 servers or more, are the largest of these.
AI-focused companies perceive size and scale as critical to their success, enabling them to perform increasing amounts of processing. Economic incentives drive the industry toward rapid expansion.
Hyperscale Insights
With greater processing capabilities comes an increase in electricity consumption, which constitutes part of a data centre’s resource needs. Additionally, as anyone who has used a laptop understands, as computer chips operate, they generate heat—excessive heat hampers their efficiency.
Consequently, over half of the energy consumed in a contemporary data centre is allocated to its cooling infrastructure.
This presents yet another obstacle: the most efficient cooling systems use water as a coolant. Due to the immense scale of data centres and the excessive heat generated by the chips, their cooling water requirements are staggering.
The statistics are astonishing: a hyperscale data centre could demand as much electricity as a town of 50,000 residents, alongside a similarly staggering amount of water. Reports indicate that data centres in the UK might already be consuming 10 billion litres of drinking water.
Regions like Buckinghamshire, which are already experiencing water supply challenges, are ill-suited to host new hyperscale data centres.
Water Crisis
Surprisingly, there is currently no national guideline on water usage for data centres, and operators have been reticent to disclose comprehensive information.
The industry often boasts about its air conditioning practices or the extent of its water recycling. However, both air-cooling and recycling bring their energy requirements, implying that a system designed to use less water may result in higher overall energy consumption.
This issue is escalating into a political crisis in the US, as seen in parts of Virginia, home to over a third of the world’s existing hyperscale data centres. Recent reports show electricity costs have surged by 267% since 2020, largely due to the energy demands created by the state’s data centres.
Last year, Virginia narrowly averted the first-ever “byte blackout“, when 20 data centres shut down, leading to a dangerous mismatch of supply and demand that threatened to disrupt thousands of homes.
It seems only a matter of time before an aging energy grid collapses under the heightened demand, and Britain’s grid, one of those under the most stress, is no exception.
Economic Discrepancies
The Trump administration acknowledges this challenge, dealing with it in its unique way.
In August, Donald Trump hosted the Pennsylvania Energy and Innovation Summit, where leaders from US Big Tech mingled with counterparts from US Big Oil, Gas, and Coal, all presented as immediate solutions to the energy needs arising from new data centres.
Nvidia’s CEO has cautioned the UK government that new gas generation will be necessary, yet the government’s own Committee on Climate Change has yet to offer forecasts on the impact of data centres on the UK’s carbon footprint.
This situation may be defensible if the economic advantages were clear, but they are not.
Data centres owned by US companies might impose significant strains on local communities, consuming precious water and overloading energy systems.
Profit Dynamics
Nonetheless, profits return to their overseas shareholders. Moreover, they yield minimal local employment. Data centres are fundamentally extensive arrays of computer systems that require very few personnel to operate.
For instance, BlackRock’s substantial £10 billion data centre campus in Blyth, Northumbria, is projected to create merely 400 full-time jobs, translating to an investment of £25 million per job. Essentially, it’s akin to constructing the energy-consuming equivalent of 50,000 homes for job creation comparable to that of a modest office building.
And not just any building, but one that will quickly deteriorate. Chips become outdated within a few years and require replacement, while the physical structures last somewhat longer.
This rapid expansion increasingly resembles a classic speculative bubble. What is required is stricter regulation and clearer guidelines regarding the construction and operation of significant data centres; however, we are currently witnessing the exact opposite.
