What to know about There’s a better way to cool data centres that cuts their huge thirst for water

The article discusses the water and energy requirements of data centers, particularly those supporting AI, and compares air-cooling methods with direct-to-chip liquid cooling. The author, a professor at the University of Limerick, argues that while evaporative cooling consumes water, it may reduce overall energy demand, and suggests that transitioning to liquid cooling could improve efficiency.
