Artificial intelligence is rapidly reshaping the technological landscape, bringing with it a host of benefits—from streamlining work processes to fueling advancements in healthcare, finance, and education. OpenAI's ChatGPT, Google's Gemini, and Microsoft's Copilot have become household names for their impressive conversational abilities and productivity enhancements. But as the world embraces AI, a rising chorus of concern surrounds the environmental cost of maintaining the massive data centers that power these technologies, particularly their voracious appetite for water and electricity. As communities across the globe grapple with increasing water scarcity and the stark realities of climate change, critical questions emerge: Is AI inadvertently hastening the depletion of our precious drinking water supplies? How do these digital marvels intersect with real-world resource challenges, and can the industry innovate a more sustainable future?
Beneath the surface of every AI conversation or image-generation prompt lies an energy- and resource-intensive process. Behind ChatGPT’s thoughtful prose, Gemini’s data synthesis, and Copilot’s code generation is a sprawling network of data centers—vast halls brimming with high-density servers, each generating enormous quantities of heat while performing complex calculations. Cooling these machines is not merely a technical requisite; it is essential for preventing catastrophic hardware failures and ensuring consistent performance.
Traditionally, server cooling relies heavily on water-based systems. Water-cooled heat exchangers and cooling towers siphon heat from server rooms and expel it into the atmosphere, consuming millions of liters of water annually at major data center sites. The environmental cost is compounded as many new data centers are sited in drought-prone areas to take advantage of cheap land and proximity to energy grids. According to media reports and analyses by organizations such as the International Energy Agency (IEA), the expanding footprint of generative AI could intensify global water stress, especially in regions already teetering on the edge of scarcity.
Recent investigations by BBC Hindi and India.com corroborate these findings, highlighting how each AI-powered interaction leaves an environmental footprint substantially larger than those of legacy web applications. When multiplied by billions of daily interactions worldwide, the cumulative resource use becomes staggering.
For example, Google's most recent environmental report reveals an annual water consumption of more than 5 billion gallons across its global data center network—a figure that has climbed steadily with the rise of machine learning workloads. Microsoft’s reported global water use also increased by over 34 percent (from 2021 to 2022 alone), an uptick widely attributed to the burgeoning demand for AI-driven cloud services and the integration of large language models into its platforms.
Tabulating the predicted rates of increase, industry analysts forecast that if left unchecked, the rapid expansion of AI infrastructure could place significant pressure on municipal water supplies in select regions, threatening local agriculture and residential access to clean water. The case is especially alarming in geographies with chronic or seasonal water shortages, where tech companies’ consumption at scale may become a flashpoint for social and political backlash.
Note: Figures based on industry projections and public utility reports; actual usage may vary by company, cooling technology, and geographic location.
For example, in the American Southwest and in parts of the Netherlands and Ireland, citizen groups and local NGOs have organized against new data center projects. Their primary fears: data centers might drain local aquifers, lower water tables, or divert supplies away from municipal or agricultural needs. Scholars warn that if left unchecked, the global expansion of AI infrastructure could exacerbate existing inequalities, concentrating environmental costs among the world’s most vulnerable populations while profits and technological benefit accrue elsewhere.
Advocacy organizations and independent media have called for more granular disclosures—not just annual water use, but breakdowns by site, process (cooling versus sanitation), and source (potable, reclaimed, or groundwater). While some companies have begun responding with enhanced sustainability reporting, much of the industry remains opaque, fueling public mistrust.
The operational phase—the period when users interact with an already-trained AI model (so-called inference workloads)—also expends considerable energy and water, especially when interactions are sustained and large scale, as with public chatbots or enterprise copilots.
Compared to traditional big tech applications (for example, e-commerce platforms or movie streaming services), AI’s water footprint per user action is many times higher. Video streaming, for instance, is energy intensive, but generative AI inference combines high processor utilization with ongoing cooling overhead, resulting in even greater water withdrawal per computational task.
Altman’s words resonate in the water debate. If the benefits of AI accrue globally, shouldn’t the industry be held accountable for global resource stewardship? As environmentalists have pointed out, failing to account for externalities such as water use could mean that AI’s promise of progress comes at a hidden and unequally distributed cost.
As AI continues to transform lives, it must also rise to the challenge of sustaining the planet. The fate of our natural resources, and of the millions who depend on them, hangs in a delicate balance with the unchecked expansion of computational power. The time for robust action is now, ensuring that tomorrow’s intelligence is, above all, sustainable.

The Surprising Water Footprint of Modern AI
Beneath the surface of every AI conversation or image-generation prompt lies an energy- and resource-intensive process. Behind ChatGPT’s thoughtful prose, Gemini’s data synthesis, and Copilot’s code generation is a sprawling network of data centers—vast halls brimming with high-density servers, each generating enormous quantities of heat while performing complex calculations. Cooling these machines is not merely a technical requisite; it is essential for preventing catastrophic hardware failures and ensuring consistent performance.Traditionally, server cooling relies heavily on water-based systems. Water-cooled heat exchangers and cooling towers siphon heat from server rooms and expel it into the atmosphere, consuming millions of liters of water annually at major data center sites. The environmental cost is compounded as many new data centers are sited in drought-prone areas to take advantage of cheap land and proximity to energy grids. According to media reports and analyses by organizations such as the International Energy Agency (IEA), the expanding footprint of generative AI could intensify global water stress, especially in regions already teetering on the edge of scarcity.
Energy Demands: AI Queries vs. Traditional Search
To grasp the scale, it is vital to understand the increased energy used by generative AI compared to traditional web searches. The IEA estimates that a single AI-enabled query (such as a prompt to ChatGPT) currently requires up to ten times more electricity than a search on Google’s classic search engine. This exponential rise in energy use subsequently raises cooling demands, which, for most hyperscale data centers, translates directly into greater water consumption.Recent investigations by BBC Hindi and India.com corroborate these findings, highlighting how each AI-powered interaction leaves an environmental footprint substantially larger than those of legacy web applications. When multiplied by billions of daily interactions worldwide, the cumulative resource use becomes staggering.
The Numbers: Water Usage and Projections
A growing body of research attempts to quantify the water consumption attributable to AI. Some estimates suggest that the AI industry could consume four to six times more water annually than an entire country such as Denmark by 2027 if current growth trends continue. Industry disclosures and environmental reports from Google, Microsoft, and Meta reflect marked upticks in both energy and water usage corresponding with the proliferation of AI applications.For example, Google's most recent environmental report reveals an annual water consumption of more than 5 billion gallons across its global data center network—a figure that has climbed steadily with the rise of machine learning workloads. Microsoft’s reported global water use also increased by over 34 percent (from 2021 to 2022 alone), an uptick widely attributed to the burgeoning demand for AI-driven cloud services and the integration of large language models into its platforms.
Tabulating the predicted rates of increase, industry analysts forecast that if left unchecked, the rapid expansion of AI infrastructure could place significant pressure on municipal water supplies in select regions, threatening local agriculture and residential access to clean water. The case is especially alarming in geographies with chronic or seasonal water shortages, where tech companies’ consumption at scale may become a flashpoint for social and political backlash.
| Year | Projected AI Industry Water Use (Billion Gallons) | Equivalent National Usage |
|---|---|---|
| 2023 | 15–18 | Roughly Denmark’s total |
| 2027 | 40–50 | 4–6x Denmark’s total |
Community Impact and Environmental Justice
As data centers mushroom across the landscape, concerns around water use escalate—not only because of the raw volumes involved, but also due to questions about privilege, access, and environmental justice. Many of the largest AI data centers are constructed in rural or semi-arid environments, often with little or no local consultation. In recent years, protests have erupted in several regions where residents perceive the tech sector’s use of scarce resources as coming at their expense.For example, in the American Southwest and in parts of the Netherlands and Ireland, citizen groups and local NGOs have organized against new data center projects. Their primary fears: data centers might drain local aquifers, lower water tables, or divert supplies away from municipal or agricultural needs. Scholars warn that if left unchecked, the global expansion of AI infrastructure could exacerbate existing inequalities, concentrating environmental costs among the world’s most vulnerable populations while profits and technological benefit accrue elsewhere.
Transparency and Reporting Challenges
Despite skyrocketing interest in the environmental cost of data centers, obtaining clear and consistent numbers is difficult. Companies categorize and report water usage differently; for some, “water withdrawal” refers to all water taken from a source, while “water consumption” measures that which is lost to evaporation or not returned to the system. These discrepancies hamper meaningful cross-company or cross-country comparisons.Advocacy organizations and independent media have called for more granular disclosures—not just annual water use, but breakdowns by site, process (cooling versus sanitation), and source (potable, reclaimed, or groundwater). While some companies have begun responding with enhanced sustainability reporting, much of the industry remains opaque, fueling public mistrust.
How Does AI Water Use Compare to Other Tech Sectors?
Large data centers have always required significant resources, but the shift to AI workloads is putting unprecedented strain on existing infrastructure. Conventional cloud and web hosting applications do use water for cooling, but the complexity and scale of large language models (LLMs) drive up demand dramatically. A 2023 Stanford/University of California study found that training a single advanced language model, like GPT-3, could consume as much electricity as 120 average homes in a year and, depending on the cooling system, millions of liters of water.The operational phase—the period when users interact with an already-trained AI model (so-called inference workloads)—also expends considerable energy and water, especially when interactions are sustained and large scale, as with public chatbots or enterprise copilots.
Compared to traditional big tech applications (for example, e-commerce platforms or movie streaming services), AI’s water footprint per user action is many times higher. Video streaming, for instance, is energy intensive, but generative AI inference combines high processor utilization with ongoing cooling overhead, resulting in even greater water withdrawal per computational task.
Are There Greener Alternatives?
The alarming projections have spurred research into mitigating AI’s water impact through engineering and policy innovation.Technological Innovations
- Air-Cooled Data Centers: Some operators are moving toward entirely air-cooled facilities. While air cooling can be less efficient in hot, dry climates and may lead to greater energy use overall, it dramatically cuts water consumption.
- Geothermal and Seawater Cooling: Iceland and other countries rich in geothermal resources have deployed data centers cooled by underground reservoirs—which require little or no potable water. Similarly, some coastal data centers experiment with direct use of seawater, though this method presents challenges in terms of corrosion, local ecosystem impact, and engineering cost.
- Closed-Loop Cooling Systems: Advanced designs seek to reuse water in closed circuits, minimizing withdrawal from municipal supplies and maximizing recirculation within the facility.
- AI Optimization: Paradoxically, research is also underway to use AI itself to optimize data center cooling operations—predicting thermal loads, adjusting chillers, and minimizing both electricity and water use in real time.
Policy Responses
- Water Use Regulations: Several jurisdictions now require new data centers to disclose projected and actual water consumption, sometimes mandating environmental impact assessments (EIA) and community engagement prior to approval.
- Renewable Energy Mandates: While not directly addressing water use, many governments require substantial percentages of data center power to come from hydro, wind, or solar, incentivizing lower overall environmental footprints.
- Economic Incentives: Tax breaks and subsidies for water-saving infrastructure help tip the economic calculus in favor of greener construction.
Corporate Sustainability Pledges
Major players, including Microsoft and Google, have made high-profile commitments to curbing their environmental impact. Microsoft, for example, aspires to be “water positive” by 2030, pledging to replenish more water than it consumes. Google, for its part, reports efforts to utilize recycled water wherever possible and invest in local water restoration projects. However, the degree to which these initiatives counterbalance the impact of growing AI workloads remains to be seen.Sam Altman and the Larger Dilemma
Sam Altman, CEO of OpenAI, has previously commented on the broader ethical and social responsibilities of AI development. In a reflective blog post, Altman acknowledged that while technological progress often improves major quality-of-life metrics over the long run—health, prosperity, education—improving fairness and equality is not automatic. “Getting this right may require new ideas,” he noted, signaling that the challenge of distributing AI’s benefits (and its burdens) must be addressed at both technical and policy levels.Altman’s words resonate in the water debate. If the benefits of AI accrue globally, shouldn’t the industry be held accountable for global resource stewardship? As environmentalists have pointed out, failing to account for externalities such as water use could mean that AI’s promise of progress comes at a hidden and unequally distributed cost.
The Debate: Strengths and Strengths Versus Risks
Notable Strengths
- Economic and Social Advancements: AI is accelerating breakthroughs in medicine, transportation, logistics, and education—fields with the potential for broad societal benefit.
- Efficiency Gains: AI can help optimize everything from energy grids to agricultural irrigation systems, sometimes resulting in net resource savings across entire sectors.
- Catalyst for Green Innovation: The same companies drawing fire for large water footprints are also investing heavily in renewable energy, water reclamation, and sustainable design—advances that may filter out into wider industrial practice.
Potential Risks
- Resource Strain: Without careful oversight, AI growth could exacerbate water shortages, especially in vulnerable regions.
- Environmental Injustice: Big tech’s water consumption often occurs away from centers of benefit, potentially intensifying inequality between stakeholders.
- Opaque Reporting: The lack of standardized water use disclosures impedes meaningful oversight, accountability, and public trust.
Solutions and the Path Ahead
Addressing the environmental cost of AI—and water use in particular—will demand coordinated action across multiple fronts:- Transparency: Universal, standardized reporting on water and energy use across all major tech firms and data centers.
- Community Engagement: Involving local stakeholders in planning and permitting new data center projects, ensuring that economic incentives do not trump environmental needs.
- Technological R&D: Accelerating the deployment of waterless cooling systems, site selection strategies that prioritize water-rich (or water-neutral) regions, and AI-powered operational optimization.
- Regulation and Oversight: Governments and international bodies must define and enforce sustainable thresholds, balancing innovation with resource stewardship.
- User Awareness: As consumers and enterprises, individuals can demand greater accountability from their digital service providers, supporting those who demonstrate genuine environmental responsibility.
