This report outlines the progress made in 2016 in the deployment of renewable energy sources (RES) in the European Union (EU) as a whole, and at country, market sector and technology level. It also provides early European Environment Agency (EEA) estimates for these developments in 2017. The report confirms that the EU's RES share remained in line with the indicative trajectory designed to lead to achieving the mandatory EU RES targets for 2020: a 20 % RES share of energy consumption and the 10 % RES sub-target for transport. However, to meet these targets with certainty will require further... efforts to deploy renewable sources of energy across the EU, especially in the context of recent increases in final energy consumption in some EU Member States. The report also shows that the additional consumption of RES across Europe since 2005 has had a number of co-benefits: it allowed the EU to cut its demand for fossil fuels and their associated greenhouse gas (GHG) emissions by about one tenth, compared with a situation in which renewables would have remained at 2005 levels. Taking a global perspective, the speed at which the EU has transformed its energy resource base between 2005 and 2016 has outpaced that of other world regions. However, while the EU is still the worldwide leader in terms of renewable power capacity per capita, it is now being surpassed by other world regions in terms of RES deployment.
