how much water has ai used in 2025

In 2025, no one has a precise, universally accepted figure for how much water all AI has used, but the best available studies suggest that AI systems are now consuming hundreds of billions of liters of water per year , on the order of the world’s annual bottled‑water consumption.

Quick Scoop

• A 2025 academic analysis by researcher Alex de Vries‑Gao estimates that AI systems alone may be using roughly 312–765 billion liters of water per year , mainly through data‑center cooling and the water used to generate the electricity they consume.

• This puts AI’s water use in the same ballpark as all bottled water drunk worldwide in a year , highlighting how fast the footprint has grown as AI deployments have exploded in 2024–2025.

• Watchdogs and NGOs warn that, if current trends continue, AI data centers could drive a jump in overall data‑center water use from about 1.1 billion to 6.6 billion cubic meters by 2027 , especially in water‑stressed regions.

Why it’s so hard to pin down

• Big tech companies disclose only partial figures, usually focusing on direct cooling water and not the much larger indirect water use from power plants that generate the electricity AI needs.

• Public estimates therefore rely on modeling and corporate sustainability reports, which means the range is wide and actual AI water use could be significantly higher or lower than current central estimates.

How this shows up per user

• One tech company suggested that a single AI prompt might use just a few “drops” of water , but independent analysts argue this is only a tiny slice of the real lifecycle footprint and omits model training and indirect water use.

• Other analysts counter the most extreme media claims (like “a bottle of water per email”), arguing that some viral statistics dramatically overstate per‑prompt usage even as they correctly point to AI’s growing environmental impact.

The bigger 2025 picture

• Advocacy groups forecast that by the late 2020s, U.S. AI infrastructure alone could demand hundreds of terawatt‑hours of electricity and up to 720 billion gallons of water annually just for cooling, unless growth slows or efficiency and policy improve.

• Governments and NGOs are beginning to treat AI data‑center siting and cooling technology as water‑policy issues , especially in drought‑prone areas where AI‑driven demand competes directly with households and agriculture.

TL;DR: No exact global number exists, but current 2025 research pegs AI’s annual water use in the hundreds of billions of liters , roughly similar to all bottled water consumed worldwide each year, and rising fast.
