US Midterms and the Global Backlash Against Data Centre Expansion

The proliferation of data centres—the foundational infrastructure for AI services, web searches, and digital banking—has reached a critical turning point as public and political opposition intensifies. According to reporting by the BBC, the global landscape of these facilities is undergoing rapid expansion, with approximately 12,250 operational and pre-operational sites recorded, up from roughly 8,000 in 2021. As the industry scales to support AI, this growth is increasingly clashing with local environmental and resource concerns.

In the United States, this tension has migrated to the political stage ahead of the 3 November midterm elections. With 16 US states now proposing legislation to block or restrict new developments, the issue has divided major political factions. Both Republican and opposition Democratic candidates have expressed resistance to these facilities. This emerging policy conflict positions critics against US President Donald Trump, who has characterized the resistance as a "sick conspiracy."

Environmental and infrastructure concerns serve as the primary drivers of this backlash. Data centres collectively consume more electricity than the entire nation of France, a trend that is straining local grids and fueling fears regarding rising energy costs and increased carbon emissions. Furthermore, the reliance on vast quantities of water for cooling systems has prompted experts to warn of potential regional water shortages. Beyond these resource pressures, local communities are voicing concerns over the physical footprint of these sites and the noise they generate.

Technological projects are also testing local tolerance. For example, the Colossus campus, which includes the Colossus 2 facility intended to power xAI’s Grok chatbot with Nvidia chips, plans to utilize 41 methane gas turbines. While activists warn this could exacerbate local air pollution, regional regulators have stated that these turbines will adhere to required air quality standards.

Despite the controversy, proponents argue that data centres are essential for national security and economic growth. According to the BBC, supporters highlight that these sites attract investment and generate construction jobs. A report from the Brookings Center corroborates that data centres provide local employment, though it suggests the scale of job creation is often lower than industry claims, with the highest benefits found in “hyperscale” facilities operated by companies such as Amazon and Microsoft.

As the tech industry gears up for projected AI infrastructure spending of $765bn in 2026—climbing to over $1tn in 2027—the sector is seeking alternatives. Suggestions include moving data centres to space or the Moon to utilize solar energy, or decentralizing AI processing to reside directly within personal smartphones and computers.
