The project Introduction of Regional Energy Concepts (CEP-REC) has the target to support the use of renewable energy sources and increase energy efficiency in Central Europe. As the use of renewable energy sources has to be implemented mainly on the regional level, the regions are key actors in this development. Regional Energy Concepts bring many chances for a good development of renewable energies and energy efficiency. Within the project CEP-REC Regional Energy Concepts will be elaborated for nine pilot regions in the eight countries from the Central Europe Programme.
