Our World in Data has published an analytical article on how much electricity data centers and artificial intelligence use, and how much energy individual AI queries consume.
- The article estimates that data centers used around 485 TWh in 2025, with AI-focused data centers accounting for about 155 TWh and 0.5% of global electricity.
- It compares IEA and S&P Global estimates, notes that crypto mining explains part of the gap, and says a typical ChatGPT/Gemini/Claude query uses only a small amount of electricity, while future AI demand remains highly uncertain.
