The International Renewable Energy Agency (IRENA) produces comprehensive, reliable datasets on renewable energy capacity and use worldwide. Renewable energy statistics 2023 provides datasets on power-generation capacity for 2013-2022, actual power generation for 2013-2021 and renewable energy balances for over 150 countries and areas for 2020-2021.

The yearbook also includes statistics on investments in renewables, compiled from the OECD-DAC database and 20 major multi-lateral, bilateral and national development financial institutions, spanning 2012-2021. The investment data is presented in millions of United States dollars (USD million) at 2020 prices.

Data on renewable power capacity represents the maximum net generating capacity of power plants and other installations that use renewable energy sources to produce electricity. For most countries and technologies, the data reflects the capacity installed and connected at the end of the calendar year.
