Debunking the Myths of the Data Center Water Footprint

Artificial intelligence (AI)-driven data center growth is reshaping not only electricity markets, but water demand across the value chain. In this episode, podcast host Reese Tisdale sits down with Research Director Amber Walsh to discuss the broader water footprint of data centers—both onsite and offsite—and why the conversation is shifting beyond cooling towers to the power generation fleet. While new AI cooling systems are becoming more efficient and, in some cases, shrinking onsite water intensity, the surge in electricity demand is driving a much larger indirect water footprint. From delayed coal retirements to new natural gas capacity and nuclear recommissioning, the power sector’s role in supporting data center growth is raising important questions about long-term water exposure. Key questions addressed: Is the AI-driven data center boom redefining water risk—from municipal cooling systems to the power generation fleet? Are data centers triggering a structural reversal in industrial water demand? Which fuel pathway—natural gas, nuclear, or extended coal—creates the most material water exposure over the next decade? Are we concentrating data center expansion in regions where power is affordable but water is constrained—and what does that mean long term? Where do market opportunities exist across the value chain? Do data centers use a lot of water?
