Global Data-Centre Boom Meets Water and Power Backlash

Core Event: Expanding Data Centres Face Growing Scrutiny over Water and Energy Use
Tech companies are rapidly building new data-centre facilities to meet soaring demand for artificial-intelligence services. The expansion has sparked public anger and regulatory attention in the United States, Australia, and South Africa because of the facilities’ high water consumption for cooling and their substantial electricity needs. Industry leaders claim new technologies can curb water use, while critics warn that trade-offs may shift the burden to power grids and raise costs for households.
Background & Context
The launch of ChatGPT in 2022 accelerated demand for AI-driven computing, prompting cloud providers to enlarge their server farms. In the United States, data centres already consume billions of litres of water for cooling; in Australia, investment has positioned the country as a potential “data-centre capital of the world.” South Africa is courting foreign tech firms to become Africa’s primary data hub, despite concerns about scarce resources.
Official Statements & Responses
- Nvidia reports its DSX system can “eliminate water consumption almost entirely” at select sites by employing a closed-loop cooling loop that circulates warmer liquid (45 °C) directly through servers.
- Microsoft, AWS and Meta assert their closed-loop systems involve “no net water loss,” emphasizing reliance on simple fans for most cooling needs.
- Prime Minister Anthony Albanese announced a forthcoming legal framework—effective for new proposals from 2027—that will require large-scale data centres to underwrite power supplies, limit water use, and fund additional water infrastructure.
Criticism & Opposition
- Andy Masley, an independent AI-data-centre researcher, notes a direct trade-off: reducing water use typically increases electricity consumption because the warmed liquid still requires cooling.
- Environmental groups in Sydney warn that the proposed facilities could strain water supplies and undermine net-zero targets, while local business owners face relocation or job losses.
- South African civil-rights organisations have called for a pause on new projects until comprehensive assessments of water, land, and electricity impacts are completed; the South African Human Rights Commission has received over 250 submissions following a May call for input.
Conflicting Reports & Gaps
- ESG reporting consistency: Microsoft and AWS publish sustainability data, but firms such as SpaceX have not released ESG reports, creating an “absence of industry-wide consistency” in disclosed water-use metrics.
- Indirect water use: The water required to generate electricity and manufacture hardware can be twice the amount directly consumed by a data centre, though precise figures vary across studies.
What’s Next
- Australia: Legislation slated for 2027 will impose water-use limits and infrastructure-funding obligations on new large-scale data centres.
- United States: Public pressure may compel additional companies to adopt Nvidia-style closed-loop cooling or disclose more detailed water-use data.
- South Africa: The Human Rights Commission’s review of the 250 submissions will inform any regulatory adjustments before further approvals.
The worldwide surge in data-centre construction is reshaping the balance between digital growth and resource sustainability, prompting a mix of technological promises, policy responses, and community resistance.
