Data Centers' Massive Water Consumption: A Hidden Environmental Cost of AI Boom

The Growing Water Footprint of Data Centers

As artificial intelligence (AI) technology continues to advance, the demand for data centers is surging worldwide. However, these digital powerhouses come with a significant environmental cost that often goes unnoticed: massive water consumption. A 2024 report from the Lawrence Berkeley National Laboratory has shed light on the alarming scale of this issue, estimating that U.S. data centers directly consumed 17 billion gallons (64 billion liters) of water for cooling in 2023 1

Projections and Indirect Water Usage

The report's projections for 2028 are even more concerning, suggesting that direct water consumption could double or even quadruple. Moreover, the indirect water usage through electricity production adds another layer to this environmental challenge. In 2023, U.S. data centers indirectly consumed an estimated 211 billion gallons (800 billion liters) of water for power generation 1

The Great Lakes Dilemma

Tech companies are increasingly eyeing the Great Lakes region for new data center locations, attracted by its cool climate and abundant water resources. However, this trend is raising concerns among researchers and environmentalists. The Great Lakes, a vital resource supporting a $6 trillion regional economy and providing drinking water to over 40 million people, could face increased pressure from these water-intensive facilities 1

Water Consumption Mechanisms

Data centers primarily use water for cooling their heat-generating servers and routers. Some facilities employ evaporative cooling systems, which constantly require cold water and release steam, while others use closed-loop systems that recirculate water but consume more energy. In extreme cases, data centers can account for over 25% of local community water supplies 1

Corporate Transparency and Reporting

An analysis of public records, government documents, and corporate sustainability reports reveals significant variability in how tech companies disclose their water usage:

1. Google: Provides individual figures for each data center, reporting over 6 billion gallons (23 billion liters) of water consumed for cooling in 2023 1

The Hidden Cost of Indirect Water Consumption

A crucial aspect often overlooked in these reports is the indirect water consumption from electricity generation. The Lawrence Berkeley Lab estimated this indirect usage to be 12 times greater than direct cooling water use in 2023, highlighting the need for a more comprehensive approach to assessing data centers' environmental impact 1
