European Union Member States have been engaged into a deep and fundamental energy transition. They adopted a comprehensive policy framework supporting RES deployment (Directive 2009/28/EC). Further, binding national targets for 2020 became a driver for RE deployment in many European countries. For 2030, the European Commission introduced the binding EU level target of at least 27% renewable energy. Beyond RE, the energy transition is driven by other major objectives: competitive, affordable, secure, innovative and sustainable energy supply. In this broader context, it is necessary to broaden the scope of the monitoring of RES deployment and provide indicators that are beyond the sole energy dimension.
