Wind power in Italy (8663 MW installed capacity) produced 15 TWh, or approximately 5% of total national electricity consumption in 2014. Italy enjoyed a steady wind energy development up until 2013, when regulatory changes reduced support for RE. The changes led to complex legislation, with uncertain rules and an
annual quota for RE, despite the EU's Renewable Energy Directive, which requires over 17% share of energy from renewable sources by 2020.
