Why Are Communities Fighting Back Against the Datacentre Boom?

Massive computing facilities known as hyperscale datacentres are facing a growing backlash because nearby residents say they ruin local living conditions through continuous noise, air pollution, and blocked sunlight, while placing enormous pressure on power grids. As artificial intelligence models expand, communities from South Wales to east London argue these resource-intensive sites deliver corporate profits to technology companies while offering few local benefits.

What is a hyperscale datacentre and why are so many being built?

Hyperscale datacentres are industrial-scale computing installations that typically contain at least 5,000 computer servers and cover a floor area of at least 10,000 square feet. Tech companies rely on these facilities to supply the immense processing power required for advanced artificial intelligence models, cloud services, and everyday data storage. Digital storage originally relied on floppy discs, internal hard drives, and corporate server rooms through the 1980s and 1990s. The sector shifted toward off-site infrastructure during the 2010s with cloud services like Google Drive, before surging again in the 2020s to support generative AI tools like ChatGPT.

Technology companies claim that larger and more centralised server compounds are necessary to handle growing processing demands. Speculative investment in these facilities has increased sharply, with global spending projected to reach $7 trillion by 2030. Figures published by The Guardian indicate that this projected expenditure would be more than double the inflation-adjusted cumulative price tag of the Apollo space programme, post-Second World War European rebuilding under the Marshall Plan, and the New Deal combined.

Why are local residents in Newport opposing their neighbouring site?

In Newport, South Wales, suburban homeowners living directly beside an expanding 46-acre datacentre campus say the complex has severely disrupted their daily lives. Dale Johnston, a former chemical company employee, has a 23-metre-high prefabricated grey building towering over his suburban garden, which completely blocks the sunlight his family previously enjoyed. Johnston told The Guardian that the treatment of the enclave of 27 neighbouring homes was "disgusting," adding that local councillors and MPs who championed the development refused to visit his garden to see the impact firsthand.

Residents on the site perimeter face continuous operational disruption even before the newest unit is fully switched on. Johnston already keeps his bathroom window shut to muffle an existing low hum from another building on the campus. His wife, who works night shifts as a nurse, struggles to sleep. To stop computer chips from overheating, the newly completed facility will run 36 sets of air blast coolers around the clock, coupled with routine operational runs of 60 auxiliary diesel generators designed to maintain data services during electrical outages. Johnston fears the testing of these diesel engines will expose nearby families to toxic exhaust fumes.

How much power will the UK datacentre pipeline consume?

The queue of planned datacentre projects across the UK requires unprecedented amounts of electricity from the national grid, the network that transports power from plants to homes and businesses. There are currently 315 hyperscale datacentres waiting for connections to the UK national grid. Combined, these prospective facilities will require 73 gigawatts of power. To put that into perspective, the typical peak energy demand across the entire country on a freezing winter day is 45 gigawatts, meaning the datacentre queue alone demands 28 gigawatts more than the nation's coldest peak load.

Wales has become a key focus area outside London, already possessing the largest datacentre capacity in Britain beyond the capital city. New developments are targeting urban and former industrial locations. The Keir Starmer-led Labour government treated this growth as an inevitable change that the country had to accept to remain competitive, creating five AI growth zones designed to accelerate planning approvals and national grid hookups. Prime Minister Andy Burnham has indicated that this strategy will continue, rejecting requests for a construction moratorium and maintaining that the facilities deliver economic gains.

Where else is community opposition emerging across Britain?

Community opposition is spreading rapidly beyond South Wales to other parts of the United Kingdom. In east London, residents are fighting the construction of a datacentre on Brick Lane. Campaigners demonstrated outside the offices of Communities Secretary Angela Rayner after she stepped in to overturn a local council decision that had rejected the scheme. Similar grass-roots groups are mobilising in rural areas such as Hertfordshire and Northumberland, where residents express frustration over the loss of traditional quality employment.

Owen Espley, a campaigner with the environmental charity Global Action Plan, works with numerous local groups resisting planned developments. Espley told The Guardian that "communities are in uproar, and most politicians are playing catch-up." He observed that petitions collect thousands of signatures within days as residents increasingly question the government position that market-driven datacentre expansion is unavoidable.

What warning signs are emerging from the United States?

British anti-datacentre campaigns point to the United States, which currently hosts roughly half of global hyperscale capacity and is experiencing an intense public backlash. Three-quarters of Americans now oppose datacentre development, citing higher domestic power bills, toxic emissions, and depleted water reserves in drought-stricken regions. In response, more than 500 American counties and municipalities have enacted temporary or permanent bans on new facilities.

The fallout from heavily clustered facilities is starkly visible in Loudoun County, northern Virginia, nicknamed Data Center Alley on account of hosting the highest concentration of datacentres anywhere on the globe. Greg Pirio, a former Voice of America radio employee, lives 150 metres from a gas-powered centre that opened last year. Pirio told The Guardian that the site's eight gas turbines roar like an airport, causing frequent headaches for neighbours and disrupting children's sleep. He reported developing chest tightness and dry eyes, and once had to leave his property due to breathing difficulties, stating that he could immediately feel the diesel generator exhaust in his lungs whenever tests occurred.

Are there alternative models for developing data infrastructure?

Campaigners argue that governments do not have to rely exclusively on large commercial developers seeking to maximise corporate earnings. Alternative approaches include implementing stricter statutory environmental regulations and investing in publicly owned data infrastructure tailored to public welfare rather than private profit. An example highlighted in The Guardian is Bristol University's new Isambard system, which focuses its computing capabilities directly on public medical research, including studies into heart disease and dementia.
