By Dr. Wil Rodríguez

Executive Summary

The rapid advancement and deployment of artificial intelligence technologies have created an unprecedented environmental challenge. As AI systems become increasingly sophisticated and ubiquitous, their energy and water consumption have reached levels that demand immediate attention from policymakers, technology companies, and environmental advocates. This research examines the growing environmental footprint of AI systems, from individual queries to large-scale training operations, and analyzes the projected impacts on global resource consumption.

Introduction

The artificial intelligence revolution has transformed how we interact with technology, offering unprecedented capabilities in everything from language processing to image generation. However, this technological leap comes at a significant environmental cost that has largely remained hidden from public view. Recent transparency efforts by major technology companies have begun to reveal the true scale of AI’s environmental impact, painting a concerning picture of resource consumption that challenges the sustainability of our digital future.

Generative artificial intelligence uses massive amounts of energy for computation and data storage and millions of gallons of water to cool the equipment at data centers. As governments and organizations worldwide grapple with climate change commitments, the environmental cost of AI has emerged as a critical issue requiring urgent attention and accountability.

The Hidden Cost of AI Queries

Energy Consumption Per Query

Google’s groundbreaking transparency initiative revealed that each Gemini text prompt consumes approximately 0.24 watt-hours of energy. While this may seem minimal for individual users, the cumulative impact becomes staggering when multiplied across billions of daily interactions. This represents the first time a major technology company has provided detailed environmental impact data for AI systems, setting a precedent for industry transparency.

The energy requirements vary significantly depending on the complexity of the AI model and the type of query. Text-based interactions generally consume less energy than image or video generation, but even these “lighter” operations contribute to the growing environmental burden when scaled to global usage patterns.

Water Consumption Patterns

Perhaps more surprising is the water consumption associated with AI operations. Google’s data indicates that each Gemini prompt requires approximately five drops of water for cooling systems in data centers. AI consumes 1.8 – 12 litres of water for each kWh of energy usage across Microsoft’s global data centres, with Ireland and the state of Washington being the most efficient locations for water usage.

The variation in water consumption depends heavily on geographic location, climate conditions, and the efficiency of cooling systems. Data centers in cooler climates naturally require less water for cooling, while those in warmer regions face significantly higher water demands.

Large-Scale Training Operations

The GPT-3 Case Study

OpenAI’s GPT-3 training operation provides a stark illustration of the environmental cost of developing advanced AI models. The training process consumed an estimated 1,287 megawatt-hours of electricity—equivalent to the annual energy consumption of approximately 120 American homes. This figure represents only the training phase and does not include the ongoing operational costs of running the model for billions of queries.

The water consumption for GPT-3 training exceeded 700,000 liters of freshwater, enough to fill two-thirds of an Olympic swimming pool. This massive resource requirement highlights the environmental trade-offs inherent in developing increasingly sophisticated AI systems.

Training vs. Inference Costs

While training large AI models requires enormous upfront energy investments, the cumulative cost of inference—running trained models to respond to user queries—often exceeds training costs over time. This shift in the environmental burden from development to deployment has significant implications for how we assess and manage AI’s environmental impact.

Global Impact Assessment

Daily Water Consumption

The scale of AI’s global water consumption has reached alarming levels. ChatGPT’s estimated daily water usage alone reaches approximately 3,500 million gallons globally. Global AI demand is expected to consume 4.2-6.6 billion cubic meters of water by 2027, surpassing Denmark’s total annual water withdrawal of 4-6 billion cubic meters.

This projection represents a fundamental shift in global water usage patterns, with AI operations competing with traditional agricultural and industrial uses for freshwater resources. The concentration of data centers in specific geographic regions can create localized water stress, particularly in areas already facing scarcity challenges.

Energy Infrastructure Strain

Since 2022, AI innovation by four leading tech companies — Google, Microsoft, Meta and Amazon — has led to annual increases in both energy and water consumption. This rapid growth has placed unprecedented demands on electrical grid infrastructure and raised concerns about energy security in regions with high concentrations of data centers.

Data Center Energy Projections

International Energy Agency Forecasts

IEA’s models project that data centres will use 945 terawatt-hours (TWh) in 2030, roughly equivalent to the current annual electricity consumption of Japan. By comparison, data centres consumed 415 TWh in 2024, roughly 1.5% of the world’s total electricity consumption.

The electricity consumption of data centres is projected to more than double by 2030, according to a report from the International Energy Agency published today. The chief culprit? Artificial Intelligence (AI).

Regional Distribution

China and the United States are the most significant regions for data centre electricity consumption growth, accounting for nearly 80% of global growth to 2030. Consumption increases by around 240 TWh (up 130%) in the United States, compared to the 2024 level.

This concentration of growth in specific regions creates both opportunities and challenges for energy infrastructure development. While it allows for focused investment in renewable energy sources, it also creates potential vulnerabilities and regional disparities in environmental impact.

Corporate Environmental Performance

Google’s Emissions Challenge

Despite implementing numerous efficiency improvements and renewable energy initiatives, Google’s emissions have increased by 51% compared to 2019 levels. This increase is primarily attributed to expanding data center capacities needed for AI training and operations, demonstrating the challenge of maintaining environmental commitments while scaling AI capabilities.

In 2024, for example, we reduced our data center energy emissions by 12% even as computational demands continued to grow, highlighting the ongoing tension between efficiency gains and scale increases.

Industry-Wide Trends

The pattern observed at Google reflects broader industry challenges. Major technology companies are investing heavily in renewable energy and efficiency improvements, yet their absolute emissions continue to rise due to the exponential growth in AI computational requirements.

Environmental Implications and Challenges

Water Resource Competition

The need for advanced cooling systems in AI data centers also leads to excessive water consumption, which can have serious environmental consequences in regions experiencing water scarcity. This competition for water resources is particularly acute in areas where data centers compete with agricultural irrigation and municipal water supplies.

Electronic Waste Concerns

The short lifespan of GPUs and other HPC components results in a growing problem of electronic waste, adding another dimension to AI’s environmental impact. The rapid pace of hardware advancement means that AI infrastructure components become obsolete quickly, contributing to the global electronic waste crisis.

Geographic Concentration Effects

In Ireland, it now accounts for over 20% of all electricity consumption. For comparison, large data centres can have a power demand equivalent to that of an electric arc furnace steel mill. However, steel plants are less likely to be clustered in the same geographic area.

This concentration creates unique challenges for local infrastructure and environmental management, as entire regions adapt to support the energy and cooling requirements of AI operations.

Regulatory and Transparency Responses

Emerging Accountability Measures

Now, legislators and regulators — in the U.S. and the EU — are starting to demand accountability. This regulatory attention represents a significant shift toward treating AI’s environmental impact as a public policy concern rather than a private corporate matter.

Proposed regulations focus on transparency requirements, efficiency standards, and environmental impact assessments for large-scale AI deployments. These measures aim to create accountability frameworks that balance innovation with environmental responsibility.

Industry Transparency Initiatives

Google’s decision to publish detailed environmental impact data for its AI systems represents a landmark moment in industry transparency. This precedent is likely to pressure other major AI developers to provide similar disclosures, enabling more accurate assessment and comparison of environmental impacts across different AI systems and providers.

Future Outlook and Projections

Scaling Challenges

Goldman Sachs Research estimates that data center power demand will grow 160% by 2030, driven primarily by AI applications. This growth trajectory suggests that current efficiency improvements, while important, are insufficient to offset the environmental impact of AI scaling.

Energy Source Transitions

Natural gas currently accounts for 26 percent of the electricity consumed by data centers, with nuclear energy holding a 15 percent share. The IEA projects that natural gas power will grow by 175TWh to meet data center demand.

The continued reliance on fossil fuels for data center operations poses significant challenges for climate commitments and raises questions about the long-term sustainability of current AI growth trajectories.

Potential Solutions and Mitigation Strategies

Technological Innovations

Rapid development and deployment of powerful generative AI models comes with environmental consequences, including increased electricity demand and water consumption. However, the same innovative capacity driving AI development also offers potential solutions through improved efficiency, better cooling systems, and more sustainable hardware designs.

Advances in AI model efficiency, including techniques like model compression, pruning, and more efficient architectures, could help reduce the environmental cost per unit of AI capability. Similarly, innovations in cooling technology and data center design offer pathways to reduce both energy and water consumption.

Policy and Governance Frameworks

The development of comprehensive policy frameworks that account for AI’s environmental impact will be crucial for sustainable development. These frameworks must balance innovation incentives with environmental protection, potentially including carbon pricing for AI operations, water usage regulations, and requirements for renewable energy adoption.

Industry Collaboration

Collaborative efforts between AI developers, energy companies, and environmental organizations could accelerate the development and deployment of sustainable AI practices. Shared standards for environmental impact measurement and reporting would enable more effective resource allocation and technological development.

Conclusion

The environmental impact of artificial intelligence represents one of the most significant sustainability challenges of the digital age. While AI technologies offer tremendous potential for addressing global challenges, their current resource consumption patterns raise serious questions about long-term sustainability.

The data revealed by companies like Google represents just the beginning of our understanding of AI’s environmental footprint. As training models become larger and more sophisticated, and as AI adoption continues to accelerate across industries and applications, the environmental stakes will only continue to rise.

The path forward requires a combination of technological innovation, regulatory oversight, and industry responsibility. Efficiency improvements alone cannot solve the environmental challenges posed by exponential AI growth. Instead, a fundamental reconsideration of how we develop, deploy, and scale AI systems may be necessary to ensure that the benefits of artificial intelligence do not come at an unsustainable environmental cost.

The choices made today regarding AI development and deployment will have lasting consequences for global energy systems, water resources, and climate goals. As the technology continues to evolve, so too must our approaches to measuring, managing, and mitigating its environmental impact. The transparency demonstrated by companies willing to share their environmental data represents a crucial first step, but much more comprehensive action will be required to address the full scale of this challenge.

The future of AI must be not only intelligent but also sustainable, requiring unprecedented cooperation between technologists, policymakers, and environmental advocates to chart a course that preserves both innovation and planetary health for future generations.
