STRAIGHT ANSWER
What is the difference between water withdrawal and water consumption?
Withdrawal is the total water taken from a source. Consumption is the part that does not return, usually because it evaporated in cooling. Discharge is what goes back. Consumption equals withdrawal minus discharge. Mixing the two makes companies look better or worse than the data supports.
The context
Amazon reports data center withdrawal (9.4 billion liters in 2025). Google and Meta report consumption (10.523 billion gallons in 2025 and 2.974 billion liters in 2024). A withdrawal number cannot be ranked against a consumption number.
What this answer does not say
- That withdrawal is harmless because most of it returns; timing, temperature, and quality of the return flow matter.
- That consumption means the water is destroyed. It re-enters the hydrologic cycle, but not locally or on time.
