Methodology & Data Sources

This dashboard is designed as a public-source reference view of AI-related energy, carbon, and water data. Below is a complete list of the sources, what is extracted from each one, and how frequently those inputs update.

Important Caveats

  • AI-specific data is estimated. Data center operators do not publicly distinguish AI from non-AI workloads. The AI share figures are derived from IEA modeling and academic research, not direct measurement.
  • Company reports use different methodologies. Scope boundaries, carbon accounting methods, and water measurement vary between providers. Direct comparisons should be interpreted cautiously.
  • Per-query figures are from Google only. The 0.24 Wh/query figure is specific to Google Gemini on Google infrastructure. Other providers and models will differ.
  • Projections are scenarios, not predictions. IEA 2030 projections represent modeled scenarios under stated policies, not forecasts.
  • Model efficiency data is approximate. The Hugging Face AI Energy Score measures GPU energy only, not full-stack (networking, cooling, storage).
  • Some model entries are normalized estimates. Where a provider does not publish directly comparable benchmark numbers, the dashboard treats those values as directional rather than authoritative.
  • The dashboard emphasizes resource-use context. It is intended to help interpret operational scale, not to measure social value, economic benefit, or downstream productivity effects from AI.

Dataset freshness currently ranges from December 31, 2024 to May 25, 2026. Each dataset is curated independently from the source listed below.
