IEA Renewables Information Database Summary (2022 Edition)

Changes from Last Edition

• Geographical Coverage:

  • Costa Rica and Lithuania are now included in OECD data starting from specific years (Costa Rica from 2021, Lithuania from 1990).
  • Argentina, Egypt, and Ukraine are added to the IEA and Accession/Association countries aggregate from 1990.
  • Several African countries (e.g., Eswatini, Madagascar) were updated by moving from regional aggregates to direct listings.

• Data Adjustments:

  • Renewable municipal waste and non-renewable portions are now distinguished for certain countries.
  • Time series breaks occurred due to statistical methodology changes or data source updates.

Database Structure

• Files and Coverage:

  • OECD and Selected Countries: Includes 38 OECD nations, 14 non-OECD countries, and 7 regional aggregates, covering data from 1990–2021.
  • WORLD File: Covers 153 countries and 22 regional aggregates, with data up to 2021.

• Product and Flow Definitions:

  • Flow definitions cover supply, consumption, transformation processes, and energy industry losses.
  • Product definitions for biofuels, waste, electricity, and heat are standardized for comparability.

Key Definitions from Flow and Product Sections

• Flow Definitions:

  • Flows include production (primary energy form), imports/exports, international marine/aviation bunkers, and statistical differences.
  • Transformation processes categorize energy conversion (e.g., power plants for electricity or heat).

• Product Definitions:

  • Biofuels include biodiesel, biogasoline, and other liquid biofuels. Solid biofuels exclude charcoal.
  • Waste categories include municipal and industrial waste, split by renewable and non-renewable portions.

Geographical Coverage

• The report includes OECD members, IEA/Accesion countries, and numerous non-OECD nations.
• Data sources vary by country, with notes on methodology differences and time series breaks.
• Special mentions include territorial status updates (e.g., European Union aggregates, regional groups).

Summary Notes

• The database enhances transparency and comparability of renewable energy data.
• Methodological updates may cause discrepancies in year-to-year comparisons for specific regions.
• Future editions aim to improve data consistency, particularly for advanced renewable technologies.
