Data Centre Backlash Intensifies as Global Expansion Hits 12,250 Sites

Opposition to data centre expansion is intensifying across multiple countries as the facilities proliferate to support artificial intelligence services, according to a BBC analysis published on 25 October 2026.^[1] The issue has become prominent enough to feature in the US midterm elections on 3 November, with both Republicans and Democrats opposing further development in some areas.

There are now approximately 12,250 data centres worldwide, according to Data Center Map, a tracking service cited by the BBC.^[1] This represents a sharp increase from around 8,000 operational sites in 2021. The facilities, which house the computer servers powering internet activity from web searches to AI chatbots, have drawn criticism over their electricity consumption and environmental footprint.

US Political Pressure Mounts

Data centre opposition has put critics on a collision course with US President Donald Trump, who dismissed concerns as a "sick conspiracy" according to the BBC report.^[1] The bipartisan nature of the backlash ahead of the 3 November midterms indicates the strength of local feeling in affected areas.

The US hosts 4,767 data centre sites, the highest concentration globally, with Europe following behind.^[1] However, when measured by capacity rather than site count, the US lead is significantly larger, with China in second place and Europe lagging further behind. This gap is projected to widen, leading to warnings that Europe may miss economic benefits from the AI boom.

Scale and Energy Demands

Data centres vary dramatically in size. The world's largest operational facility is reportedly run by China Telecom in Hohhot, Inner Mongolia, covering approximately one million square metres (10.7 million square feet) - equivalent to about 140 FIFA football pitches, according to the BBC.^[1]

Even larger sites are under construction to meet AI computing requirements. These newer facilities are being built exclusively to provide the processing power needed for AI services. For example, Colossus 2, part of the wider Colossus campus, will house hundreds of thousands of advanced AI chips manufactured by Nvidia.^[1] The site will be used to train xAI's chatbot Grok, with Elon Musk's company deploying 41 methane gas turbines to power the facility.

Data centres have traditionally been located near cities where access to high-voltage power lines and water resources for cooling is easier. However, as facilities expand in size, more are being constructed in rural areas, bringing environmental debates to communities previously unaffected by the sector.^[1]

UK Register Context

Across the UK company register, 5,436,174 companies were recorded as active as of the most recent count, with 15,282 incorporations registered in the past seven days.^[2] These economy-wide figures reflect overall business formation activity across all sectors.

Daily incorporation totals across the entire UK register have varied significantly in recent weeks, ranging from 128 companies on 27 October 2026 to 3,540 on 30 September 2026.^[2] These fluctuations are typical of register-wide activity and reflect data processing timelines rather than specific sectoral trends.

London remains the dominant location for registered companies across the UK, with 1,064,399 companies having London addresses, followed by Manchester with 105,630 and Birmingham with 93,476.^[2] Other major business centres include Glasgow (71,658), Edinburgh (59,147), Cardiff (56,541), and Bristol (55,577). These are economy-wide totals across all industries.

Environmental and Infrastructure Concerns

The BBC report describes data centres as "giant, warehouse-like buildings" that power "virtually all our internet activity, from our web searches and emails to movie downloads and online banking."^[1] They are described as being "at the heart of the AI boom, housing the advanced computer chips and servers needed to run services like ChatGPT and Claude."

The speed of expansion, enormous electricity consumption, and environmental impact concerns are cited as primary drivers of the public backlash.^[1] The BBC notes that until a few years ago, many people may have been "blissfully unaware" of what a data centre was, but growing visibility and local impacts have changed public awareness.

The use of methane gas turbines at some facilities, such as the 41 turbines planned for the Colossus 2 site, has drawn criticism from environmental activists according to the BBC report.^[1] Water usage for cooling systems represents another contentious issue in areas facing water stress.

Economic Trade-offs

The data centre debate reflects broader tensions between economic development and environmental protection. Proponents argue the facilities are essential infrastructure for digital services and AI development, while opponents point to resource consumption and local disruption.

The warning that Europe risks missing economic benefits from the AI boom if capacity expansion lags behind the US and China illustrates the perceived stakes for policymakers.^[1] However, this economic imperative must be balanced against local environmental impacts and community concerns that have proven strong enough to unite opposing political parties in the US ahead of the midterm elections.

As data centre development continues to accelerate globally, the backlash documented by the BBC suggests regulatory and planning frameworks may need to evolve to address public concerns while meeting the infrastructure demands of AI and digital services.
