Why are data centres becoming a major issue in the US midterms?

Data centres have turned into a significant political battleground ahead of the US midterm elections on 3 November. Both Republican politicians and opposition Democrats are coming out against the development of these massive facilities. This growing political and public pushback places opponents of data centre expansion at loggerheads with Donald Trump, the American leader, who has rejected the grievances as a "sick conspiracy".

What are data centres and why are they growing so fast?

Data centres are giant, warehouse-like buildings that power virtually all internet activity, including web searches, emails, movie downloads, and online banking. They sit at the heart of the current artificial intelligence boom by accommodating the sophisticated processing units and servers that execute applications such as ChatGPT and Claude. According to Data Center Map, there are approximately 12,250 operational and pre-operational data centres globally, marking a sharp increase from around 8,000 sites in 2021. Data centres vary wildly in size, from small units fitting inside a garden shed to massive spaces sprawling across enormous territories internationally. The largest operational site on earth is managed by China Telecom located in Hohhot inside the Inner Mongolia region, occupying roughly one million square metres, an area matching about 140 Fifa football pitches. Meanwhile, even larger facilities are currently under construction exclusively to provide the computing power needed for AI. For instance, the Colossus 2 project, functioning as a component of the broader Colossus facility grouping, will accommodate hundreds of thousands of advanced Nvidia AI chips and power Elon Musk's xAI chatbot Grok.

Where are data centres located and how much power do they use?

Facilities housing digital infrastructure are most heavily concentrated within the United States, which hosts 4,767 sites, trailed by European nations where the United Kingdom and Germany take the lead. When looking at actual capacity, the US maintains an even larger lead, with China occupying the second position and Europe trailing far behind. Traditionally, these facilities were built near cities to easily access high-voltage power lines and water resources for cooling. However, as the sites grow larger, an increasing number are being constructed in rural areas. Globally, data centres are estimated to utilize greater quantities of electrical energy than the entire nation of France. This heavy reliance on electricity is escalating greenhouse gas output and putting severe pressure on municipal power networks, causing worries among analysts that electricity tariffs might climb.

What are the environmental and community concerns?

The rapid expansion of these digital warehouses has triggered a widespread public backlash over their environmental footprint and the strain they place on local resources. Cooling these systems demands substantial volumes of water, prompting certain specialists to caution about prospective scarcity issues. In addition, local residents worry about the noise the buildings generate and the sheer amount of space they take up. Air pollution is another major worry; for example, the xAI site powering Grok plans to use 41 methane gas turbines, which activists warn could significantly increase local air pollution, though local regulators insist that emission outputs will comply with established environmental protection rules.

How are politicians and local communities responding?

Public anger and environmental worries have translated directly into legislative action across the United States. Approximately sixteen American states have introduced legislative bills aimed at prohibiting or halting the construction of new complexes, setting up data centres as a focal point for the November midterm elections. Outside the United States, opposition has also surfaced in countries such as Mexico, France, Indonesia, and the UK. On the other side of the debate, supporters argue that safeguard systems and artificial intelligence advancement rely fundamentally on these facilities. Proponents also maintain that the facilities are positive for the economy by drawing in capital, producing tax receipts, and establishing employment opportunities.

What economic benefits do data centres actually bring?

While industry advocates highlight job creation, a recent report from the Brookings Center suggests that while data centres do create local jobs, the total is lower than claimed by the industry. The report found that the type of facility matters significantly. Hyperscale facilities, which are massive sites owned and operated by major technology conglomerates like Amazon and Microsoft, have a larger positive effect on local employment. Conversely, multi-tenant server facilities that rent out floor area to distant clients lacking any physical community presence deliver vastly reduced local advantages. Despite the mounting backlash and policy hurdles, tech industry spending on AI infrastructure is projected to reach $544bn this year and top $1tn next year. To address environmental concerns, the industry is exploring alternatives, such as placing data centres in space or on the Moon to harness solar energy, or shifting more AI processing directly into the hardware inside personal computers and smartphones.
