Why Do AI Data Centres Use So Much Water ? | Explained

Artificial Intelligence powers everything from ChatGPT and Gemini to social media feeds, online shopping, and digital assistants. But behind every AI response lies a hidden environmental cost that few people talk about: water. As AI adoption accelerates worldwide, massive data centres are consuming enormous quantities of water to cool thousands of servers running around the clock. Researchers estimate that AI infrastructure could use up to 6.6 trillion litres of water annually by 2027—comparable to the yearly water consumption of entire countries. Why does AI need so much water? How much water does a single AI interaction consume? And what happens when these facilities expand in regions already facing severe water shortages? In this video, we break down the growing water footprint of AI, the role of data centres, the sustainability challenges facing tech giants, and why countries like India could be especially vulnerable as demand for AI infrastructure rises. The future of AI may depend not only on computing power—but also on one of the world's most precious resources: water.
