Renewable Energy Statistics

At 84% of new electricity capacity added worldwide, renewables are no longer a sidebar but the default build choice, while onshore wind power costs cluster around $0.03–$0.06 per kWh in the IRENA dataset. The page connects that build momentum to impacts you can feel, including millions of avoided health outcomes and a measurable pull on power sector CO2, with global renewable capacity now sitting around 5,600 GW.
