The Ecological Impact of Generative AI: A Deep Dive into Its Environmental Footprint

The rapid advancement of generative artificial intelligence (AI) has sparked significant interest worldwide, alongside mounting concerns regarding its ecological footprint. This critical issue will be a focal point at the upcoming global summit in Paris on February 10-11, 2025, as stakeholders seek to address the environmental implications of these powerful technologies. Here, we explore key data points and possible future projections regarding the environmental impact of generative AI.

Energy Consumption: A Growing Concern

Every interaction with OpenAI’s popular chatbot consumes approximately 2.9 watt-hours of electricity. This figure is notably ten times greater than the energy used for a single Google search, as reported by the International Energy Agency (IEA).

With an impressive user base of 300 million consumers making one billion requests daily, these energy consumption levels become concerning. The staggering growth in usage reflects a broader trend where generative AI technologies are rapidly being integrated into daily life.

Widespread Adoption Among Youth

Generative AI applications have gained significant traction, particularly among younger demographics. A survey conducted by Ifop found that 70% of 18- to 24-year-olds in France reported using generative AI technologies. Similarly, a Morning Consult poll revealed that 65% of American teenagers aged 13 to 17 engage with generative AI, with nearly half of the general population also utilizing these platforms.

Data Centres: The Backbone of Generative AI

Underpinning the functionality of generative AI are data centres, which host vast amounts of information and computing power. Recent studies highlight that as of 2023, data centres accounted for nearly 1.4% of global electricity consumption. Projections show that this percentage could rise to 3% by 2030, consuming approximately 1,000 terawatt-hours (TWh) of electricity—equivalent to the combined annual energy use of France and Germany.

The IEA anticipates a more than 75% escalation in data centre power consumption by 2026, increasing from 2022 levels to 800 TWh.

Future Electricity Shortages?

The burgeoning demand for AI applications could result in severe electricity shortages. A report from American consultancy Gartner indicated that up to 40% of newly established data centres designed for AI functionalities may face power supply issues by 2027.

Greenhouse Gas Emissions: A Hidden Cost

The training of large language models (LLMs) plays a critical role in generative AI’s proliferation, but it comes at a cost—one training session can generate substantial greenhouse gas emissions. Researchers at the University of Massachusetts Amherst estimated that training one LLM produces around 300 tonnes of carbon dioxide, roughly equivalent to 125 return flights between New York and Beijing. Oxford researchers later suggested that this amount could be 224 tonnes for OpenAI’s GPT-3 model.

Despite these estimates, accurately assessing the overall greenhouse gas emissions associated with generative AI remains challenging. Experts point to insufficient information regarding model production and a lack of global measurement standards.

Water As a Resource

In addition to energy, water consumption for cooling computer hardware is another area of concern. A conservative estimate suggests that generating between 10 and 50 responses with GPT-3 requires approximately half a litre (a pint) of water. Overall, the anticipated demand for water due to AI could span between 4.2 billion and 6.6 billion cubic metres—four to six times Denmark’s annual water consumption.

The E-Waste Challenge

The burgeoning popularity of generative AI raises another pressing issue—electronic waste. In 2023 alone, approximately 2,600 tonnes of e-waste, including graphics cards and servers, were linked to AI applications. Should current trends persist without intervention, researchers predict that this figure could skyrocket to 2.5 million tonnes by 2030, essentially the equivalent of discarding 13.3 billion smartphones.

Additionally, AI equipment often requires rare metals for production. The extraction processes for these metals, particularly in Africa, can have devastating environmental repercussions.

Conclusion

As the generative AI landscape evolves, the pressing environmental concerns surrounding its energy consumption, water usage, and electronic waste become increasingly urgent. Stakeholders must engage in critical discussions regarding sustainable practices to mitigate the ecological footprint of this burgeoning technology.
