Artificial intelligence-driven data centers are rapidly expanding in already water-scarce regions, sparking environmental concerns. These facilities are essential for AI operations but consume enormous amounts of water for cooling, exacerbating local shortages and provoking protests globally. As AI continues to grow, the competition for limited water resources intensifies, challenging tech companies to balance innovation with sustainability.

**The big picture:** The rise in AI data centers has led to a 70% increase in facilities in water-stressed areas since 2022.
– About two-thirds of new data centers are being built in regions with high water stress, with five U.S. states accounting for 72% of these centers.
– Countries like Saudi Arabia and the UAE are seeing similar trends due to the AI boom.

**Why this matters:** The expansion of data centers threatens local water supplies, agriculture, and energy production.
– Communities in water-scarce areas may face increased competition for clean water, potentially leading to conflicts.
– The environmental impact challenges tech companies’ sustainability commitments, including reducing carbon footprints and becoming water positive by 2030.

**Key details:** AI data centers consume millions of liters of water daily, contributing significantly to water stress.
– An average 100-megawatt data center uses about 2 million liters of water per day, equivalent to the usage of 6,500 households.
– Globally, data centers consume around 560 billion liters of water annually, a figure projected to rise significantly by 2030.

**What they’re saying:** Experts emphasize the need for transparency and innovative solutions to address the water-energy nexus.
– “It is very much a growing issue — and it is spreading everywhere,” said Newsha Ajami from Lawrence Berkeley National Laboratory.
– Tech companies like Microsoft are exploring new cooling technologies to reduce water usage, though these often require more energy.

**Searching for a solution:** Companies are experimenting with alternative cooling methods to mitigate water use.
– Innovations include closed-loop cooling systems that recycle water and immersion cooling technologies.
– Despite efforts, most AI data centers still rely on evaporation-based cooling systems, which are water-intensive.

**Lack of transparency:** There’s a call for tech companies to be more transparent about their water usage.
– Some firms, like Google, have begun providing more detailed reports, but many data centers remain opaque regarding their water consumption.
– Efforts by local governments to obtain data center water usage information have often been met with resistance.

**The bottom line:** As the AI industry continues to expand, balancing technological advancement with environmental sustainability remains a critical challenge.
– The ongoing development of data centers in water-stressed regions underscores the urgent need for innovative solutions and transparent practices to ensure water resources are managed sustainably.
