Overall, the total impact on the economy is assessed to be weak in absence of productivity gains in the RES sector and of improved competitiveness on the world markets. In particular, in the electricity sector, it induces the production of new power generation and storage capacities but also the development of network infrastructure. In 2010, investment in renewable facilities accounted for EUR 26.6 billion (0.1% of GDP), 2.6 higher than in 2005 (a 21% annual increase). Employment in RES sectors has also increased sharply over the past two decades, with more than 370 000 persons employed in 2010, three times more than in 2002 (BMU, 2011).
