Renewables kept accelerating in 2023, with global renewable capacity reaching about 5,600 GW and new additions totaling roughly 473 GW. Yet the same year also shows why the transition is never just about building capacity, from onshore wind costs and curtailment rates to air pollution and health gains. This post pulls together the key renewable energy statistics, from electricity shares in the US and EU to investment, emissions reductions, and the performance metrics that make grids work.

- Renewable electricity became the largest source of power generation in the EU in 2023 — renewables led electricity generation by source
- Renewable energy accounts for 30% of power sector emissions reductions since 2010 (relative to a fossil baseline) — sector decarbonization contribution estimate
- Renewables reduced global NOx emissions by 1.3 million tonnes in 2022 — avoided nitrogen oxides emissions
- Renewables avoid approximately 2.1 million premature deaths per year globally from air pollution in the power sector — health impact estimate
- In 2023, global renewable energy capacity additions totaled about 473 GW — new renewables capacity installed
- Global solar PV capacity reached about 1,600 GW by end-2023 — total solar PV installed capacity
