Faced with the rapid expansion ofartificial intelligence (AI), many environmental challenges are emerging, exacerbating the debate on its ecological footprint. Although progress has been made in terms ofenergy efficiency, the ever-increasing consumption of electricity and water as well as the dependence on carbon-based energies raise significant concerns. According to a BloombergNEF report, despite efforts, carbon emissions of AI technologies would only be reduced by 34% compared to their 2005 level. AI, driven by energy-intensive infrastructures and ever more powerful models, requires colossal resources, accentuating its impact on the environment.
As artificial intelligence (AI) continues to evolve at a rapid pace, its environmental impact is becoming a major concern. Although initiatives have been launched to reduce energy consumption, the ecological footprint of AI threatens to spiral out of control. This article examines the different aspects of this issue, focusing on environmental challenges, mitigation efforts and technical improvements, while asking the question of user education in the face of this growing challenge.
Energy Consumption and Dependence on Carbon Energy
Despite advances in energy efficiency, AI consumption of electricity and resources continues to grow. Dependence on carbon energy remains a concern, leading to a significant carbon footprint. Reports indicate that AI-related carbon emissions would only be reduced by 34% from 2005 levels, while the national target is a 50-52% reduction by 2030, according to BloombergNEF.
The Burden of Big Tech
Web giants such as Google, Microsoft and OpenAI are investing heavily in infrastructure dedicated to AI, sometimes neglecting the energy costs involved. Microsoft, for example, reactivated the Three Mile Island nuclear power plant, a site infamous for a radiological accident. For its part, Google is struggling to achieve its carbon neutrality goals, raising red flags in the technology sector.
Towards Responsible Use of AI
However, some industry players are now favoring less energy-intensive AI development. Smaller models, requiring less power, are starting to emerge. This approach helps maintain optimal efficiency while reducing power consumption. Small-scale AI has the advantage of running on traditional devices, such as smartphones and personal computers.
Cooling and Water Consumption Challenges
Besides electricity, cooling data centers poses another major problem. These use cooling towers which consume a lot of water. Data shows that Microsoft’s water consumption increased by a third, Google’s by 21% compared to 2021. This aspect is crucial to understanding the overall environmental impact of AI.
The Jevons Paradox and the Rebound Effect
The Jevons paradox, or rebound effect, suggests a potential increase in overall consumption despite technological innovations aimed at efficiency. Indeed, even if technologies improve, the growing demand for AI services could lead to an inevitable increase in resource use, making sustainability gains ineffective.

Teaching and Education in the Use of AI
To mitigate the environmental impacts of AI, user education becomes essential. Pierre-Yves Oudeyer, researcher at Inria, suggests that users be informed of the ecological consequences of their actions. In the future, growing awareness could be one of the key solutions to integrate sustainable use of AI into our daily lives.
