Context

Data centers generate enormous heat that must be dissipated. The most common cooling method uses water — evaporative cooling towers that consume millions of gallons per day. As AI drives explosive data center growth, water consumption is becoming a critical issue. Data centers are being built in regions already facing water stress. A single large data center can consume as much water as a small city, competing with agriculture, residential use, and ecosystems for an increasingly scarce resource.

Hypothesis

What people believe

Cloud computing is environmentally efficient compared to on-premise infrastructure.

Actual Chain
Water consumption at industrial scale(Large data center: 1-5 million gallons per day)
Evaporative cooling is the most cost-effective method — and the most water-intensive
A single Google data center uses as much water as 29,000 households
AI workloads generate more heat per rack — requiring more cooling
Data centers compete with communities for water in stressed regions(Data centers built in drought-prone areas for tax incentives)
The Dalles, Oregon: Google data center uses 25% of city's water
Mesa, Arizona: data centers approved despite severe drought conditions
Agricultural water rights challenged by data center demand
Corporate water reporting is opaque(Most tech companies don't disclose per-facility water use)
Aggregate water reporting hides impact on specific communities
'Water positive' pledges rely on offsets, not actual consumption reduction
Climate change worsens the problem(Hotter temperatures require more cooling, while water becomes scarcer)
Feedback loop: data centers contribute to warming, warming increases cooling needs
Drought conditions make evaporative cooling unsustainable in many regions

Don't If

  • You're building data centers in water-stressed regions without alternative cooling
  • Your water reporting doesn't disclose per-facility consumption

If You Must

  • 1.Use air cooling or liquid cooling instead of evaporative cooling where climate permits
  • 2.Build in regions with abundant water and cool climates (Nordics, Pacific Northwest)
  • 3.Disclose per-facility water consumption transparently
  • 4.Invest in water recycling and treatment for cooling water

Alternatives

  • Liquid cooling (direct-to-chip)Uses 90% less water than evaporative cooling — becoming standard for AI workloads
  • Nordic/cold climate locationsFree air cooling eliminates water use entirely — Iceland, Finland, Norway
  • Waste heat recoveryUse data center heat for district heating — turns waste into community benefit
Falsifiability

This analysis is wrong if:

  • Data center water consumption decreases despite growing compute demand through efficiency improvements
  • Data centers in water-stressed regions do not measurably impact local water availability
  • Alternative cooling technologies eliminate water consumption for data centers at comparable cost
