UN analyzes data center impact
A United Nations University report reveals that the environmental impact of data centers, particularly their electricity and water consumption and carbon emissions, already rivals that of some of the world's largest countries. The report projects that this footprint will double by 2030, driven significantly by the increasing use of artificial intelligence. It emphasizes the urgent need for greater transparency and responsible growth within the data center industry.
A new report from the United Nations University warns that the environmental footprint of global data centers already parallels that of some of the world's largest countries, with its electricity and water usage, and carbon emissions projected to double in the next four years. This substantial growth is primarily attributed to the expanding use of artificial intelligence (AI).
The report, co-authored by Kaveh Madani, a water scientist and director at the United Nations University Institute for Water, Environment and Health, revealed that global data centers consumed 448 trillion watt-hours of electricity last year, surpassing all but ten countries, and generated 208 million tons of carbon dioxide. By 2030, data centers are forecast to account for nearly 3% of global electricity use, reaching 935 trillion watt-hours, which would position them as the sixth-highest power consumer globally. Approximately 20% of current data center energy use is AI-driven, a figure expected to climb to 40% by 2030, with 90% of AI's power consumption stemming from operational requests rather than training.
Experts and industry representatives have reacted to the findings. Fengqi You, a Cornell University energy engineering professor, lauded the U.N. institution for comprehensively framing the environmental impacts of AI and data centers, calling for public concern without panic. Jean Su, director of the Energy Justice Program at the Center for Biological Diversity, highlighted the report's significance as the first global assessment of AI's environmental harms. In contrast, Caleb Max, President of the National Artificial Intelligence Association, emphasized the industry's efficiency gains and AI's societal benefits, while Josh Levi, President of the Data Center Coalition, affirmed the industry's commitment to responsible and transparent growth. Madani stressed that despite appearing clean, AI's underlying infrastructure has tangible environmental costs, advocating for more concise AI queries to reduce energy consumption.
