Why it matters
Three numbers worth knowing
Figures from the IPCC and the International Energy Agency, rounded. Each guide links to its own sources.
+1.1 °C
Global surface warming since the late 19th century, according to the IPCC Sixth Assessment Report (2021).
~90 %
Share of global electricity capacity added in recent years that is renewable, as reported by the IEA (2023, 2024).
−10 to −30 %
Typical household energy saving from insulation, heating controls and efficient appliances, depending on the home and the climate.
