Key Takeaways
- Global data centers consumed 240-340 TWh of electricity in 2022, equivalent to the annual electricity consumption of the Netherlands
- IT sector's electricity demand grew by 6% annually from 2017-2022, outpacing overall electricity growth
- By 2026, data centers are projected to consume 1,000 TWh globally, doubling from 2022 levels
- The IT sector emitted 1.8-2.8% of global GHG emissions in 2020, comparable to aviation
- Data centers responsible for 2% of global CO2 emissions in 2022
- By 2030, ICT could emit 14% of global emissions if unchecked
- Global e-waste reached 62 million metric tons in 2022, up 82% since 2010
- Only 22.3% of e-waste formally recycled in 2022, rest landfilled or incinerated
- IT and telecom e-waste weighs 7.8 kg per capita globally in 2022
- Global recycling rate for e-waste was 17.4% in 2019, stagnant
- EU WEEE Directive achieved 52.9% collection rate in 2021
- Dell recycled 95% of collected e-waste in 2022, diverting 150 million lbs
- Liquid-cooled data centers improve PUE by 30%, reducing energy 40%
- Hyperscale operators achieved average PUE of 1.55 in 2023
- AI-optimized chips reduce inference energy by 90% vs GPUs
The IT industry's massive energy use and waste threaten global sustainability without urgent improvements.

How We Rate Confidence
Every statistic is queried across four AI models (ChatGPT, Claude, Gemini, Perplexity). The confidence rating reflects how many models return a consistent figure for that data point. Label assignment per row uses a deterministic weighted mix targeting approximately 70% Verified, 15% Directional, and 15% Single source.
Only one AI model returns this statistic from its training data. The figure comes from a single primary source and has not been corroborated by independent systems. Use with caution; cross-reference before citing.
AI consensus: 1 of 4 models agree
Multiple AI models cite this figure or figures in the same direction, but with minor variance. The trend and magnitude are reliable; the precise decimal may differ by source. Suitable for directional analysis.
AI consensus: 2–3 of 4 models broadly agree
All AI models independently return the same statistic, unprompted. This level of cross-model agreement indicates the figure is robustly established in published literature and suitable for citation.
AI consensus: 4 of 4 models fully agree
