Detailed, accurate and timely data and statistics are essential for the monitoring and evaluation of renewable energy policies and deployment. IRENA helps analysts, policy makers and the public make informed decisions by providing access to comprehensive and up-to-date renewable energy data. IRENA publishes detailed statistics on renewable energy capacity, power generation and renewable energy balances. This data is collected directly from members using the IRENA Renewable Energy Statistics questionnaire and is also supplemented by desk research where official statistics are not available. Renewable power-generation capacity statistics are released annually in March. Additionally, renewable power generation and renewable energy balances data sets are released in July. IRENA’s statistics unit helps members to strengthen their data collection and reporting activities through training and methodological guidance. Member countries are encouraged to participate in this process.
