The Hidden Environmental Cost of AI: Data Centres' Surging Energy and Water Consumption

 In recent years, artificial intelligence (AI) has become an integral part of our daily lives, powering everything from smart assistants to complex data analysis. However, as AI technologies continue to advance and proliferate, a concerning trend has emerged: the rapidly increasing energy and water consumption of data centres that support these systems.

The Power Hunger of AI

According to the International Energy Agency (IEA), global data centre electricity demand is projected to more than double between 2022 and 2026, largely due to the growth of AI. In 2022, data centres consumed approximately 460 terawatt-hours (TWh) globally, and this figure is expected to exceed 1,000 TWh by 2026. To put this into perspective, that's equivalent to the entire electricity consumption of Japan.

The energy intensity of AI-related queries is particularly striking. While a typical Google search uses about 0.3 watt-hours (Wh), a query using ChatGPT requires around 2.9 Wh - nearly ten times more energy. This difference highlights the substantial energy demands of AI systems compared to traditional computing tasks.

In the United States, the impact is even more pronounced. The Electric Power Research Institute (EPRI) estimates that data centres could consume between 4.6% and 9.1% of US electricity by 2030, up from the current 4%. This significant increase raises concerns about the strain on power grids and the potential need for expanded infrastructure.

Thirsty Data Centres

Energy isn't the only resource being consumed at an alarming rate. Data centres also require substantial amounts of water for cooling systems. In Goodyear, Arizona, for example, Microsoft's data centres are projected to consume over 50 million gallons of drinking water annually. This heavy water usage is particularly concerning in regions already facing water scarcity issues.

Environmental and Social Consequences

The surge in data centre resource consumption has far-reaching implications:

  1. Climate Goals: Despite pledges to run on carbon-free energy, tech giants like Google and Microsoft have seen increased greenhouse gas emissions due to their AI pursuits. This trend poses challenges for companies striving to meet their climate commitments.
  2. Local Impact: Communities are beginning to push back against data centre expansion. In Dublin, Ireland, there is a de facto moratorium on new data centres due to their significant energy consumption.
  3. Infrastructure Strain: The growing demand for data centre capacity is putting pressure on local power grids and water supplies, potentially affecting access for other users.
  4. Economic Implications: The need for increased power infrastructure will lead to financial burdens on taxpayers for future power lines and grid upgrades. Of course there is no guarantee that the increased productivity, should it accrue, from the AI deployments will be reflected in wage growth, on the contrary it is far more likely to increase inequalities.

The Whispers in the Machine: Why Prompt Injection Remains a Persistent Threat to LLMs

 Large Language Models (LLMs) are rapidly transforming how we interact with technology, offering incredible potential for tasks ranging from content creation to complex analysis. However, as these powerful tools become more integrated into our lives, so too do the novel security challenges they present. Among these, prompt injection attacks stand out as a particularly persistent and evolving threat. These attacks, as one recent paper (Safety at Scale: A Comprehensive Survey of Large Model Safety https://arxiv.org/abs/2502.05206) highlights, involve subtly manipulating LLMs to deviate from their intended purpose, and the methods are becoming increasingly sophisticated. At its core, a prompt injection attack involves embedding a malicious instruction within an otherwise normal request, tricking the LLM into producing unintended – and potentially harmful – outputs. Think of it as slipping a secret, contradictory instruction into a seemingly harmless conversation. What makes prompt inj...

Can We Build a Safe Superintelligence? Safe Superintelligence Inc. Raises Intriguing Questions

  Safe Superintelligence Inc . (SSI) has burst onto the scene with a bold mission: to create the world's first safe superintelligence (SSI). Their (Ilya Sutskever, Daniel Gross, Daniel Levy) ambition is undeniable, but before we all sign up to join their "cracked team," let's delve deeper into the potential issues with their approach. One of the most critical questions is defining "safe" superintelligence. What values would guide this powerful AI? How can we ensure it aligns with the complex and often contradictory desires of humanity?  After all, "safe" for one person might mean environmental protection, while another might prioritise economic growth, even if it harms the environment.  Finding universal values that a superintelligence could adhere to is a significant hurdle that SSI hasn't fully addressed. Another potential pitfall lies in SSI's desire to rapidly advance capabilities while prioritising safety.  Imagine a Formula One car wi...

The Future of Work in the Age of AGI: Opportunities, Challenges, and Resistance

 In recent years, the rapid advancement of artificial intelligence (AI) has sparked intense debate about the future of work. As we edge closer to the development of artificial general intelligence (AGI), these discussions have taken on a new urgency. This post explores various perspectives on employment in a post-AGI world, including the views of those who may resist such changes. It follows on from others I've written on the impacts of these technologies. The Potential for Widespread Job Displacement Avital Balwit, an employee at Anthropic, argues in her article " My Last Five Years of Work " that AGI is likely to cause significant job displacement across various sectors, including knowledge-based professions. This aligns with research by Korinek (2024), which suggests that the transition to AGI could trigger a race between automation and capital accumulation, potentially leading to a collapse in wages for many workers. Emerging Opportunities and Challenges Despite the ...
