UN report: AI could double electricity use by 2030, drain global water supply
Synopsis
Key Takeaways
A new United Nations report has warned that artificial intelligence could double its electricity consumption by 2030, accounting for roughly 3 per cent of global power use and generating greenhouse gas emissions comparable to those of the United Kingdom. The report, released around 5 June, also cautioned that AI's water demand for cooling could exceed the annual drinking water needs of the entire global population.
The Scale of AI's Energy Footprint
According to the UN report, data centres already consumed as much electricity as Saudi Arabia last year. Should electricity use double by 2030, the resulting carbon footprint would require 6.7 billion trees grown over a decade to offset. Beyond energy, data centres are projected to need approximately 9.3 trillion litres of water and occupy land nearly ten times the size of Mexico City to sustain that level of growth.
The Jevons Paradox and AI Efficiency
The report invokes the concept of the Jevons paradox — first observed by economist William Stanley Jevons in 19th-century England, where efficiency gains in coal use lowered costs, ultimately driving higher overall consumption rather than reducing it. The UN warns that AI faces the same dynamic: as models become cheaper and more capable, new use cases and higher usage volumes will emerge, eroding any savings from efficiency improvements. In effect, making AI more efficient may simply accelerate its adoption and total resource draw.
A Widening Digital and Environmental Divide
The report highlights a stark geographic imbalance: only 32 nations currently host AI-specific cloud infrastructure, with 90 per cent of that capacity concentrated in the United States and China. Countries that consume AI services without hosting the infrastructure bear a disproportionate environmental burden through mineral extraction and e-waste. This emerging divide, the report argues, risks compounding existing inequalities between the Global North and South.
What the UN Is Recommending
To avoid what it describes as an unsustainable trajectory, the UN has laid out a roadmap for responsible AI development built on six guiding principles: transparency, efficiency by design, equity and justice, lifecycle responsibility, global cooperation, and sustainable use. Critically, the report urges routine environmental disclosures at both the model and task level, and calls for full value-chain governance — from mineral sourcing through to recycling and safe disposal of hardware.
What Comes Next
The report's findings arrive as AI investment continues to accelerate globally, with major technology companies announcing ever-larger data centre buildouts. Whether voluntary disclosure frameworks will be sufficient — or whether binding international standards will be required — remains an open question. The UN's call for global cooperation suggests that unilateral national policies may be inadequate to address a problem that is, by its nature, borderless.
