AI’s Hidden Cost: Why Water Risk Belongs on Every Investor’s Radar

AI’s rapid growth is driving demand not only for electricity but also for the clean water needed to run its physical infrastructure. As data centers expand, rising water intensity is straining supplies and testing long-term sustainability. In our analysis, these pressures create both risks and opportunities for active investors.

How Cool Is AI?

AI’s explosive growth shows little sign of ebbing, with a record $350 billion projected for AI-focused business investment in 2025 alone. As a result, global capacity for AI’s server-housing facilities, or data centers, is expected to rise 23% in each of the next five years, with the US dominating.

The build-out is expected to spike data-center electricity demand by 160% in the US, contributing to a 25% increase in overall power demand through 2030, according to the International Energy Agency. Meeting greater global power needs will have distinct challenges. But we also see a variety of potential risks stemming from water becoming either more scarce or less pure.

This is because AI’s powerful data centers tend to run extra hot, and many of them require a lot of ultrapure water to constantly chill them. Consequently, a data center’s success will likely depend as much on access to ample and clean water as on reliable power sources.

Rising Water Risk as a Market Disrupter

Data centers aren’t the only AI boom participants in search of water. Semiconductor manufacturers and utilities are also intensive water users and are likely to need even more of it (Display). US power generation—particularly coal and nuclear—accounts for about 70% of all freshwater withdrawals, though most is returned to its source after cooling.

Research we conducted with the Columbia Climate School shows that these three areas combined are expected to grow demand for clean water by 33% through 2030. Location can also add material risk, since many data centers are either situated in or planned for regions already stressed for water, our findings show.

We see a continued ramp-up in data center build-out, chip production and power generation in the near term. And water risk is emerging as a key constraint for these and other industries—potentially more disruptive than climate change itself. For instance, a Bloomberg study found that about $70 trillion in global GDP could be directly exposed to high water stress by 2050.

We’re already seeing companies change up their long-term playbooks due to near-term water concerns—Constellation Brands’ now-abandoned beer plant in Mexico and Google’s nixed plans for a data center in Chile, for example.

That’s why we believe water stewardship is integral to active investment selection. By the same token, company engagement is crucial to determining a business’s water-risk exposure and whether it’s helping to solve the problem for its own benefit and in some cases for others.
