International Renewable Energy Agency (IRENA) provides reliable datasets on global renewable energy capacity and use. The 2024 report includes data on power-generation capacity (2014–2023), actual power generation (2014–2022), and energy balances (2021–2022) for over 150 countries. Data is sourced from IRENA surveys, national statistics, industry reports, and other reliable sources.
Investment statistics (2013–2022) are included, based on data from OECD-DAC and 20 major financial institutions, presented in USD at 2021 prices. Renewable power capacity reflects the maximum net generating capacity of installations, measured in megawatts (MW), while generation is reported in gigawatt-hours (GWh). Pumped storage is included under hydropower but excluded from total renewable energy figures.
