Communities on both sides of the Atlantic are pushing back against the rapid growth of data centres, which are pivotal for the expanding artificial intelligence sector. This backlash is generating heated political and environmental debates, forcing countries to wrestle with complex questions about how technological advancements intersect with local interests and national priorities.
Mounting Political Tensions in the US and UK
The escalating need for artificial intelligence has triggered a surge in demand for sprawling data centres, high-powered sites filled with processors carrying out trillions of calculations each moment. Despite their largely invisible operations, data centres are generating significant real-world consequences: their high energy requirements are driving up electricity prices and prompting widespread resistance that is now influencing policy across the United States and United Kingdom.
Bipartisan unease about the spread of data centres is most pronounced within progressive circles in the US. For instance, Democratic Senator Bernie Sanders has put forward a proposal for a moratorium on new centres, highlighting the public’s doubts about the unchecked pace of technological development, the deficit in local governance, and increasing fears regarding electricity and water use. Sanders commented, “People are looking around worried about how quickly the technology is moving, how little control they have over it, how will data centres impact their community in terms of electric rates and water utilisation.”
Rising Public Opposition Reflected in Polls
The extent of community opposition is starkly illustrated in recent polling. According to a Gallup poll released in May, 71% of Americans surveyed were opposed to hosting a data centre in their vicinity—a level of resistance even greater than that for nuclear power facilities. Over the past two years, this discontent has grown, with some surveys showing that up to half of Americans support a total stop to building new sites.
The political consequences of these attitudes were on display during the 2023 gubernatorial races in New Jersey and Virginia, both areas with dense clusters of data centres. Voters, frustrated by hikes in electricity rates linked to the industry’s expansion, favoured Democratic candidates who advocated for more rigorous oversight of the use of water and power by these facilities.
Elsewhere, popular backlash has led to the ousting of city councils, and both Democrat- and Republican-controlled states have taken steps to curtail or outright halt further data centre construction. Grievances often centre on the strain placed on local power grids and water systems, as well as higher household bills.
Pressure Builds in the UK as Data Centres Multiply
Similar tensions are present in the UK, which is the third largest host of data centres worldwide. Locals in areas including Slough and East London are objecting to multiple data centre proposals, expressing unease over the environmental burden, missed opportunities to build social housing, and skepticism about anticipated economic gains.
In Slough, now considered the top data centre hub in Europe, more than 500 residents signed a petition to stall further expansion. There was notable outrage over a particular project built on land once designated for 1,000 new homes. The local council repurposed the area due to a pressing need to address municipal debts, prompting public anger.
Elsewhere in London, such as Brick Lane, critics contend that planned data centre developments—likely geared toward supporting the City’s high-frequency trading—are threatening affordable housing and established businesses. Baroness Pola Uddin, a former Labour peer, has called for policies that better protect the welfare of area residents, arguing there should be “proper consideration of the health and wellbeing of the local population… We must consider the option of more industrial areas.”
Regulatory Shifts and Political Change
To hasten the construction of essential projects, the British government last year recognized data centres as Critical National Infrastructure. Officials maintain that these facilities are necessary for both public service delivery and the nation’s global competitiveness. However, such national imperatives often lead to conflict with local authorities, especially when ministerial decisions override local council input—as occurred in Buckinghamshire, where the approval of a contentious green-belt project was later reversed by campaigners in court.
Another core concern is water supply. In submissions to a Commons committee, the trade group Water UK criticized the government for neglecting to address water supply risks in its strategies, stating, “There appears to be an assumption that the country will always have enough water for its economic needs. Nothing could be further from the truth.”
Efforts to increase British data centre output—targeting 6 gigawatts (GW) of continuous electricity demand by 2030, a threefold rise—have sparked debate about the implications for the UK’s net zero goals. Forthcoming updates in the National Policy Statement are set to introduce new benchmarks for what qualifies as a “nationally significant” infrastructure project.
The evolving landscape is further complicated by the recent shift in national leadership, with Labour Prime Minister Andy Burnham promising “growth in every postcode.” This pledge brings into focus the friction between centralized initiatives and demands for robust local oversight, particularly as environmental organizations and the Green Party advocate for a pause on new data centres.
Economic Implications and International Competition
Though the UK’s projected AI-driven data centre expansion is on a much smaller scale compared to the US—the British 2030 target is just a twentieth of the American goal—it remains a contentious subject. Supporters argue that building domestic infrastructure protects “data sovereignty” and reduces dependency on outside providers, whereas detractors emphasize that these facilities create few permanent jobs and present unresolved sustainability issues.
In contrast, US lawmakers who previously welcomed data centres with tax breaks for data centres are reversing course, now considering tougher regulations, increased taxation, or even criminal penalties for operators if linked AI systems endanger children’s safety online.
Even as tech figures such as Jensen Huang of Nvidia champion AI infrastructure as essential for revitalising industry and addressing climate action, the fate of AI’s physical underpinnings remains uncertain. Local protests and recalibrated political strategies across the US, UK, and beyond ensure that the debate over data centres is far from settled.
