Study maps at least 25% of data centers in regions facing seasonal water shortfalls

In brief

  • Lorenzo Rosa and colleagues mapped thousands of data centers against local water availability.
  • At least 25% of data centers sit where water demand exceeds supply at certain times of year.
  • Seasonal water shortages could affect data center operations, the study indicated.
  • The study doesn't directly link data centers to local water shortages.

What the study actually mapped

So what does the 25% figure say? The work, conducted by Lorenzo Rosa and colleagues, plotted thousands of data center sites against how much water is available locally. It's a location study. The headline number (at least one in four facilities) refers to sites in regions where demand for water outstrips supply during parts of the year, not all year round.

That seasonal detail matters. According to Crypto Briefing's report, the study indicated those shortages could affect data center operations.

There's a limit worth stating plainly.

The study doesn't directly link data centers to local water shortages. It doesn't show the facilities draining local supplies; it shows where they sit relative to supplies that already run short at certain times of year. Readers shouldn't treat the 25% figure as evidence that data centers caused the water stress in those regions.

Why resource management is in focus

Crypto Briefing said the findings raised concern about resource management, particularly in areas with high water stress. That's the outlet's framing of the study's relevance, and it's where the policy conversation comes in.

Oklahoma and Louisiana, per Crypto Briefing

In its own commentary, Crypto Briefing tied the study to Oklahoma and Louisiana, where it said discussions about possible moratoriums on data centers were already underway. The outlet named legislative action or statements from Oklahoma Governor Kevin Stitt as indicators to watch. In Louisiana, it pointed to any moves by Governor Jeffrey M. Landry or the state legislature toward a moratorium as developments to follow.

Those are things the outlet said to watch for. They aren't steps it reported either governor or either legislature has taken, and Crypto Briefing's report doesn't indicate that the study itself addresses state policy in Oklahoma or Louisiana.

Frequently asked questions

Does the study show that data centers cause local water shortages?

No. The study by Lorenzo Rosa and colleagues mapped thousands of data centers against local water availability, but it doesn't directly link data centers to local water shortages. It shows where facilities are located relative to regions where water demand exceeds supply at certain times of year.

How many data centers are in regions with seasonal water shortages?

At least 25% of the world's data centers are located in regions where water demand exceeds supply at certain times of the year, according to the study as reported by Crypto Briefing. The study indicated those seasonal shortages could affect data center operations.
