If you’re concerned about the strain on our planet’s resources, you can’t ignore how Big Tech’s data centers draw vast amounts of water to keep their servers cool—often in areas already facing drought. Companies like Amazon and Google aren’t always clear about just how much they use, or where that water comes from. So, what does that mean for local communities and the future of digital growth?
The Scarcity of Fresh Water and Rising Demand
Despite the vast coverage of water on Earth, only approximately 0.5% of that water is accessible for human and ecological use.
This limited availability highlights the significant issue of freshwater scarcity, which is becoming increasingly urgent.
Increasing population and rapid industrial growth—particularly in sectors like data centers—are contributing to greater demand for water resources.
As data centers compete for local water supplies, it's critical to consider the implications of energy efficiency, the integration of renewable energy sources, and effective water management practices.
Understanding direct and indirect water use is vital for responsible resource management, ensuring that the needs of both society and ecosystems can be met.
How Data Centers Consume Water
Data centers play a critical role in the functioning of today's digital infrastructure, yet their water usage is a significant consideration. A substantial portion of a data center's water consumption is attributed to cooling systems, particularly evaporative cooling technology, which uses considerable amounts of water for each kilowatt-hour of energy consumed.
Projections indicate that with the increased deployment of AI technologies, the direct water consumption in data centers may double or even quadruple by the year 2028.
Moreover, approximately 20% of data centers are situated in regions experiencing water stress, which raises concerns about their sustainability and environmental impact. It's also important to note that the process of microchip manufacturing contributes to the indirect water footprint of data centers, further compounding the issue.
To accurately assess the impact of data centers on water resources, it's essential to establish transparent practices regarding water use and to implement consistent reporting mechanisms. This enables a better understanding of their overall water consumption and its implications on local water supplies.
Data Centers’ Impact on Regional Water Resources
Data centers play a significant role in our digital infrastructure, but their substantial water consumption represents a critical challenge for local water resources, particularly in regions already facing water scarcity.
The primary driver of a data center's water usage is the need for cooling systems, which can lead to annual consumption of millions of liters.
As artificial intelligence technologies and high-demand server applications expand, so too does the water consumption associated with them, increasing the potential for a local water crisis.
Currently, approximately 20% of data centers in the United States operate in watersheds that are already categorized as water-scarce. This situation raises concerns among local communities and utilities regarding the sustainability of water resources.
In response to these pressures, there's growing demand for data centers to adopt more efficient water use practices and to provide transparency about their water consumption and conservation efforts.
As climate change continues to influence water availability, the impact of data centers on local water resources remains an important point of consideration for sustainability initiatives and regional planning.
Water Usage: The Amazon Case and Industry Comparisons
As technology companies expand their digital infrastructure, their water consumption has become a significant concern, particularly regarding Amazon's practices.
In 2021, Amazon reported a total water use of 10.5 billion gallons, but only 7.7 billion of that was classified as primary water use. Meanwhile, Google's water usage, reported in 2023, totaled 6.4 billion gallons, indicating a higher level of transparency in its disclosures.
Amazon has committed to reducing its primary water usage and has initiated its AWS Water Positive campaign; however, these efforts have faced criticism for not factoring in the indirect water footprint, which constitutes approximately 90% of its total water consumption.
This selective reporting could pose reputational risks and raises questions about the authenticity of the company's sustainability initiatives. The contrasts in reporting practices between Amazon and Google underscore the importance of comprehensive disclosure in assessing corporate environmental responsibility.
Primary, Secondary, and Indirect Water Footprints
Water use in the technology sector is multifaceted and extends beyond the simple act of turning on a faucet. Data centers, for example, account for significant primary water consumption, particularly for cooling systems. In 2023, U.S. data centers used approximately 66 billion liters of water.
However, an important aspect often overlooked is the secondary water footprint, which includes water that's recycled or returned to the environment. This component is frequently absent from corporate water strategies and sustainability claims, creating challenges in achieving transparency regarding overall water use.
Additionally, the indirect water footprint—comprising water utilized in supply chain processes and microchip manufacturing—can account for a substantial portion of total water usage, sometimes reaching up to 90%. This highlights the necessity of addressing all dimensions of water consumption to obtain a comprehensive understanding of a company's water impact.
Without focusing on all aspects of water use, a true assessment of water impact may remain ambiguous, underscoring the need for improved reporting and accountability within the industry.
Challenges in Tracking and Reporting Water Consumption
A comprehensive understanding of water use in the tech sector necessitates an examination of the various water footprints associated with operations, as well as a commitment to consistent reporting practices.
Tracking water consumption in data centers presents significant challenges, particularly amidst the rapid expansion driven by advancements in AI technologies. The degree of transparency regarding water use varies among major tech companies; for example, Amazon doesn't publicly disclose its total water consumption, while Microsoft and Google provide such information in their reports.
The absence of standardized reporting regulations contributes to the complexity of accounting for indirect water use, leading to potential inconsistencies in sustainability reporting. Numerous corporate sustainability reports omit critical data on water consumption, making it difficult to compare water usage effectively across different organizations within the sector.
The lack of regulatory frameworks and uniformity hinders efforts to address and mitigate sustainability challenges associated with water usage, highlighting the need for improved reporting standards to facilitate better understanding and management of water resources in the tech industry.
The Push for Transparency and Regulatory Changes
There's a growing demand for transparency in the operations of tech companies, particularly regarding the water consumption of their data centers.
As part of ongoing regulatory changes within the European Union, new mandates will require these companies to report both their water and energy usage. The purpose of these regulations is to enhance transparency and promote sustainability, especially in regions experiencing water scarcity or stressed water resources.
Local governments and activist groups are increasingly pressuring tech companies to provide detailed data on their water usage. This push for accountability is rooted in the necessity of establishing public trust, which relies on the availability of accurate and comprehensive information.
However, many tech companies often limit their disclosures, citing concerns over trade secrets, which complicates the establishment of uniform reporting standards.
Inconsistent reporting practices pose an ongoing challenge in this context. Addressing these challenges is critical for fostering informed decision-making and supporting broader sustainability initiatives within the tech industry.
Enhanced transparency in water and energy reporting is essential to enable stakeholders to evaluate the environmental impacts of data center operations effectively.
