Data centre backlash grows ahead of US midterms - here's what you need to know - BBC News
Data centers, vital for AI and internet activity, are rapidly expanding, leading to a growing public backlash due to their immense electricity and water consumption, environmental impact, and local resource strain, becoming a key issue in US politics.

The rapid proliferation and increasing scale of data centers, essential infrastructure for the AI boom, are sparking significant public opposition globally. Concerns primarily revolve around their massive energy and water demands, environmental footprint, and local impact, transforming them into a contentious political issue, particularly in the US ahead of midterm elections.
Imagine giant computer brains that help run all your online games and videos. These brains need huge buildings, called data centers, and they drink a lot of electricity and water, like a thirsty giant. People are getting worried because there are so many of them, and they're getting so big, that they might use up too much power and make too much noise in our towns.
Analysis
The rapid proliferation of data centers, the foundational infrastructure for the burgeoning AI industry, is encountering significant public and political resistance. These colossal facilities, which underpin virtually all digital activities from web searches to advanced AI models like ChatGPT, have seen their numbers surge globally. According to Data Center Map, there are approximately 12,250 operational and pre-operational sites worldwide, a substantial increase from around 8,000 in 2021. The United States leads this expansion with 4,767 sites, followed by Europe, with the UK and Germany at the forefront. While historically located near urban centers for power and water access, the increasing size of these facilities is pushing new developments into rural areas, intensifying local concerns. This geographical shift often brings these massive, resource-intensive operations into closer proximity with communities unaccustomed to such industrial scale, fueling the growing opposition.
12,250 Data Centres
The sheer scale of data center expansion is a primary driver of the growing backlash. The global count of these facilities has jumped dramatically in just a few years, reflecting the escalating demand for computing power, particularly from the AI sector. This growth is most pronounced in the US, which hosts a disproportionate share of the world's data centers and capacity, creating a widening gap with regions like Europe. Experts warn that Europe's lag in data center capacity could hinder its ability to fully capitalize on the economic benefits of the AI boom, potentially impacting its competitive standing in the global tech landscape.
The strategic placement of these centers is also evolving. Traditionally, proximity to high-voltage power lines and water sources for cooling dictated their location, often near major cities. However, as individual data centers grow to immense proportions, developers are increasingly seeking out larger, more affordable land parcels in rural settings. This shift, while practical for developers, often brings significant infrastructure demands and environmental impacts to communities less equipped to handle them, leading to localized protests and political mobilization against new projects.
Colossus 2
The scale of individual data center projects underscores the immense resource requirements of modern AI. An illustrative example is Colossus 2, part of a larger campus, designed to house hundreds of thousands of advanced AI chips from tech giant Nvidia. This facility is also slated to train xAI's chatbot, Grok, highlighting its critical role in cutting-edge AI development. To power such an enormous operation, Elon Musk's company plans to utilize 41 methane gas turbines.
This reliance on methane gas has drawn sharp criticism from environmental activists, who warn that these turbines could "significantly increase" local air pollution. While local regulators assert that the turbines will meet air quality standards, the controversy exemplifies the tension between technological advancement and environmental stewardship. The sheer energy density and computational demands of training large AI models necessitate power solutions that often come with substantial environmental footprints, making projects like Colossus 2 focal points for public debate and regulatory scrutiny.
France's Electricity Consumption
The environmental and resource burden of data centers is a central theme in the public backlash. Globally, these facilities are estimated to consume more electricity than the entire country of France, a staggering figure that highlights their collective impact on energy grids and carbon emissions. This insatiable hunger for power is not only driving up carbon footprints but also putting immense pressure on local electricity grids, leading to fears of increased energy prices for residents and businesses in affected areas.
Beyond electricity, data centers also require vast amounts of water for cooling their systems, a demand that some experts warn could lead to water shortages in regions already facing scarcity. The combined impact of noise pollution, land occupation, and resource strain has galvanized opposition, particularly in the US, where 16 states have proposed laws to ban or temporarily block new facilities. This issue is poised to be a significant factor in upcoming midterm elections, demonstrating how the infrastructure of the AI boom is becoming a potent political battleground, extending beyond the US to countries like Mexico, France, Indonesia, and the UK.
Key points
- Data centers, essential for AI and internet services, are rapidly increasing in number and size globally.
- Their immense electricity and water consumption, along with noise and land use, are fueling a significant public backlash.
- The issue has become a political flashpoint in the US, with proposed laws to ban or block new facilities in 16 states.
- Globally, data centers consume more electricity than the entire country of France, contributing to carbon emissions.
- While supporters highlight economic benefits like jobs and investment, critics point to environmental and resource pressures.
Supporters argue that data centers are vital for national security and AI development, attracting investment, generating tax revenue, and creating jobs, particularly for hyperscale facilities. Future innovations like space-based data centers or localized processing on devices could also mitigate current environmental concerns.
The unchecked growth of data centers risks exacerbating local resource strains, including water shortages and pressure on electricity grids, potentially driving up energy prices and increasing carbon emissions. The growing public and political opposition could lead to bans or significant regulatory hurdles, hindering AI infrastructure development.
