AI did not just demand more electricity — it demanded water. By 2025, U.S. data centres, increasingly expanded for AI workloads, were consuming nearly one trillion litres of water a year, much of it used in cooling systems that shed heat by evaporating water into the air.

Source Summary

The public argument about artificial intelligence has mostly been an argument about electricity. Bigger models, denser chips and new data centres have put fresh pressure on power grids that were not built with this pace of computing demand in mind. But the same buildings also demand something quieter, more local and often more politically sensitive: [...] The post AI did not just demand more electricity — it demanded water.
