AI’s Hidden Thirst: How ChatGPT and Other AI Models Are Draining Our Water Supply
Artificial intelligence has transformed how we work, communicate, and solve problems. But behind every smart chatbot, recommendation engine, and predictive model is an unseen cost: water.
To keep the powerful servers that run AI models cool, massive data centers consume millions of gallons of water—every single day. And as the AI boom continues, the water footprint of digital infrastructure is growing fast.
Why Does AI Need Water?
AI itself doesn't use water, but the data centers that power it do. These facilities contain thousands of high-performance chips running 24/7, which generate extreme heat. To stay operational, they rely on cooling systems—many of which depend heavily on water.
There are two primary methods:
- Direct liquid cooling, where water circulates through heat sinks to absorb heat from processors.
- Evaporative cooling, where water is evaporated to lower the ambient air temperature inside the facility.
As AI demands more computational power, the need for water-based cooling continues to rise.
Real Numbers Behind AI’s Water Use

Recent research and industry reports offer sobering data:
- Training GPT-3, one of OpenAI's earlier large language models, consumed approximately 700,000 liters of fresh water during training in U.S.-based Microsoft data centers. That’s roughly the amount of water needed to produce 320 Tesla Model Ys.
(Source: University of California, Riverside, 2023) - A single interaction with ChatGPT, depending on its location and energy source, can indirectly consume up to 500 milliliters of water when factoring in power generation and cooling systems.
- A large data center can use between 3 to 5 million gallons of water per day, depending on climate, energy source, and cooling technology.

Global Trends and Regional Impact

Water usage for AI isn’t just high—it’s growing.
- By 2027, global data centers are projected to withdraw up to 6.6 billion cubic meters of water per year, which is more than the entire annual water consumption of Denmark.
(Source: Wikipedia on AI's environmental impact) - In Virginia, home to one of the largest concentrations of data centers globally, annual water use increased from 1.13 billion gallons in 2019 to 1.85 billion gallons in 2023, driven largely by AI workloads.

Solutions in Progress

There are strategies to reduce AI's water footprint, and some companies are already implementing them.
Recycled Cooling Systems
Some data centers now use closed-loop water systems that recycle the same water multiple times before disposal, dramatically reducing net consumption.
Locating in Cold Climates
Building facilities in northern regions like Canada, Scandinavia, or Iceland allows companies to use ambient air cooling, avoiding water use altogether.
Optimized AI Models
Efforts are underway to create smaller, more efficient AI models that require less compute power, which in turn reduces energy and cooling demands.
Public Water Reporting
There is a growing push for tech companies to publish their water usage statistics, much like carbon disclosures, to allow public accountability and responsible planning.
A Crossroads: Innovation vs. Sustainability
Artificial intelligence has the potential to help humanity fight climate change, predict droughts, and optimize water use. But if we’re not careful, it could also exacerbate water scarcity in already vulnerable areas.

As we expand our digital capabilities, we must ask hard questions:
- Is it ethical to develop smarter AI if it threatens basic human water needs?
- Can technological progress and environmental responsibility coexist?
Final Thoughts
Water is one of the world’s most valuable and vulnerable resources. Every prompt you send to a chatbot, every image you generate, and every model that gets trained—there’s water behind it.
If we want AI to benefit the planet, not harm it, sustainability must become part of the design process—not an afterthought.
