Examining US official’s claim that data centres ‘don’t use water’

A recent public statement by United States Commerce Secretary Howard Lutnick has sparked widespread fact-checking scrutiny after he incorrectly asserted that data centers operate without consuming any water. The claim, which contradicts decades of industry data and environmental research, has drawn attention to the often-overlooked water footprint of the global digital infrastructure that powers cloud computing, artificial intelligence, and internet services worldwide.

Data centers, the centralized facilities that house thousands of servers to process, store, and distribute digital data, rely heavily on water for cooling purposes. Even the most advanced air-cooled data center designs require water for periodic system maintenance, while the more common water-based cooling systems used by large-scale hyperscale data centers pull millions of gallons of water annually to regulate the heat generated by running server equipment. Industry analysts note that as demand for AI computing and cloud storage surges, the water consumption of data centers has become an increasingly pressing environmental and community issue, particularly in regions facing chronic drought and water scarcity.

Fact-checking organizations and technology policy experts have quickly debunked Lutnick’s claim, pointing to public sustainability reports released by major tech companies that operate large data center networks. Companies including Google, Amazon, and Meta regularly disclose their annual water withdrawals for data center operations, acknowledging the industry’s significant water use and outlining plans to reduce consumption through efficiency improvements and alternative cooling technologies. The incorrect statement has also reignited debate over regulatory transparency for digital infrastructure development, as many local governments approving new data center projects face growing pushback from community groups concerned about strained local water supplies.
