A United Nations University report reveals that the environmental footprint of data centres is comparable to that of large countries, with predictions of doubling water and energy use due to AI growth. AI currently accounts for 20% of data centres' energy use, expected to rise to 40% by 2030. The report highlights the significant carbon emissions and water consumption associated with data centres, urging users to be more concise in their AI queries to reduce energy consumption. Experts emphasize the need for transparency in the industry and the importance of addressing the environmental impacts of AI.
