• In 2001 the French government initially planned to produce 21% of its electricity consumption with in 2010 to comply with European directive of 27 September 2001. This means that France had to produce 106 TWh of renewable energy in 2010, up from 71 TWh in 2006. Wind power represents 75% of the 35 TWh additional production in 2010. • In 2016 installed capacity rose above 1 GW for the first time during the year.
