UK Greens Call for Moratorium on New Data Centres Amid Energy and Land Concerns
The United Kingdom’s Green Party has called for an immediate pause on the approval and construction of new data centres, arguing that the facilities place an unsustainable burden on the national electricity grid and compete with housing and agricultural land at a moment when both are in critically short supply. The demand signals that the fierce political battles over digital infrastructure already playing out in the United States and Ireland may be arriving in earnest on British shores.
Data centres have expanded rapidly across the UK in recent years, drawn by the country’s stable regulatory environment, strong fibre connectivity, and proximity to major financial markets. The greater London area in particular has emerged as one of Europe’s largest data centre hubs, a status that has brought jobs and investment but has also attracted growing scrutiny from planners, energy regulators, and environmental campaigners concerned about the cumulative impact of the facilities.
Grid Pressure and Green Objections
At the heart of the Green Party’s objection is electricity consumption. Data centres are energy-intensive by nature, and the surge in artificial intelligence workloads has pushed demand projections sharply higher across the industry. According to reports, some regional grid operators in England have already flagged lengthy queues for new grid connections, with data centre projects accounting for a significant share of pending applications. Critics argue that prioritising commercial computing infrastructure over renewable energy schemes or residential development represents a misallocation of scarce grid capacity.
The Greens are also raising concerns about land use, pointing to cases where proposed facilities on the edges of towns and cities have encountered local opposition over their visual impact, noise from cooling systems, and the loss of greenfield sites. These objections mirror tensions seen in parts of Ireland, the Netherlands, and several US states, where data centre growth has prompted moratoriums, planning restrictions, or outright bans in certain jurisdictions.
The party’s position stops short of calling for existing facilities to close or for the UK to retreat from the digital economy. Instead, according to reports, the Greens are seeking a temporary halt to new approvals while the government conducts a comprehensive review of how data infrastructure expansion can be reconciled with net-zero commitments and local planning needs. They are also understood to be pressing for stronger requirements that new facilities source power directly from renewable generation rather than drawing from the general grid.
The UK government has so far shown little appetite for restrictions. Ministers have publicly backed data centre investment as a pillar of the country’s artificial intelligence strategy, and the sector received formal recognition as critical national infrastructure last year — a designation that affords operators certain planning and security protections. Industry groups argue that modern facilities are already far more energy-efficient than their predecessors and that the sector’s economic contribution, including well-paid technical jobs, justifies continued expansion.
Whether the Green Party’s call gains traction beyond its own membership will depend partly on how the broader energy supply debate evolves. With the government under pressure to accelerate grid upgrades and expand renewable capacity simultaneously, competition for available power is likely to intensify. The data centre question may yet move from the margins of environmental politics toward the mainstream of UK energy and industrial policy, much as it has in several of its European neighbours.
