For over ten years now, EurObserv’ER has been collecting data on European Union renewable energy sources to describe the state and thrust of the various sectors in its thematic barometers. The first part of this assessment is an updated and completed summary of the work published in 2011 in Systèmes Solaires (Journal des Énergies Renouvelables nos. 203, 204, 205 and 206, Journal de l’Éolien no. 8 and Journal du Photovoltaïque no.5). It provides a complete overview of the ten renewable sectors, supplemented by two summary notes on concentrated solar power and ocean energies. Their performances are compared against the 2020 targets of the European Commission directive and the Renewable Energy National Action Plan targets. This edition also provides a monitoring of socio-economic indicators (employment and turnover) for all sectors and for the 27 countries of the European Union. This 11th edition includes a new chapter with seven regional cases that have succeeded in attracting private investments in their territories to develop projects based on renewable technologies.
