JRC-IDEES-2021

The Joint Research Centre's Integrated Database of the European Energy System (JRC-IDEES) compiles a rich set of information allowing for highly granular analyses of the dynamics of the European energy system, so as to better understand the past and create a robust basis for future policy assessments. The JRC-IDEES-2021 release contains a consistent set of disaggregated energy-economy-emissions data for each Member State of the European Union, covering all sectors of the energy system for the 2000-2021 period: industry, buildings, transport, and power generation. This data complies with Eurostat energy balances while providing a plausible decomposition of energy consumption into specific processes and end uses. In each sector, JRC-IDEES uses a vintage-specific approach to characterize the energy-using equipment in operation. It accordingly identifies different drivers and provides insights on their role while accounting for structural differences across countries. As such, JRC-IDEES has several key applications for energy-related research and policy analysis, such as the parameterization of energy models and the assessment of past and prospective policies.
