Section Key Insights Important Data / Metric Primary Source Types of Data Center Water Consumption Water use is categorized into direct (onsite cooling) and indirect (electricity generation). Direct: Cooling towers, evaporative cooling, humidification. Indirect: Water used by power plants generating electricity. Nature Water Usage Effectiveness (WUE) Industry-standard metric for measuring water efficiency. Lower values indicate better efficiency. WUE = Annual Water Usage (Liters) ÷ IT Equipment Energy (kWh) Annual Water Consumption by Facility Type Water consumption varies significantly depending on facility size and cooling technology. Enterprise: 5–20 million gallons/year; Colocation: Up to 110 million gallons/year; Hyperscale: Up to 5 million gallons/day EESI Impact of AI Workloads AI clusters generate significantly…
