The International Renewable Energy Agency (IRENA) produces comprehensive, reliable datasets on renewable energy capacity and use worldwide. Renewable energy statistics 2025 provides datasets on power-generation capacity for 2015-2024, actual power generation for 2015-2023 and renewable energy balances for over 150 countries and areas for 2022-2023.

Data was obtained from various sources, including an IRENA questionnaire, official national statistics, industry association reports, consultant reports and news articles. Major trends in the sector worldwide are outlined in the accompanying brief, Renewable energy highlights.

The yearbook also includes statistics on investments in renewables, compiled from the OECD-DAC database and 16 major multi-lateral, bilateral and national development financial institutions, spanning 2014-2023. The investment data is presented in millions of United States dollars (USD million) at 2022 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.

Capacity is presented in megawatts (MW), while generation is presented in gigawatt-hours (GWh). Pumped storage, although included in part of hydropower data, is excluded from total renewable energy. The previous editions and complete electricity generation and capacity dataset from 2000 onwards are available for download on the Data and Statistics web pages. Tools to analyse the data further are also available here and here.
