The countries of the European Union are the number two global leaders in the development and application of renewable energy. Promoting the use of renewable energy sources is important both to the reduction of the EU's dependence on foreign energy imports, and in meeting targets to combat global warming.
The Maastricht Treaty set an objective of promoting stable growth while protecting the environment. The Amsterdam Treaty added the principle of sustainable development to the objectives of the EU. Since 1997, the EU has been working towards a renewable energy supply equivalent to 12% of the total EU's energy consumption by 2010.
The Johannesburg Summit failed to introduce the radical changes targeted for ten years after the Rio Summit. No specific goals were set for the energy sector, which disappointed many countries. While the EU had proposed an annual increase in the use of renewable energy at a rate of 1.5% worldwide until 2010, Johannesburg's action plan did not recommend such a "substantial" increase, with no concrete goals nor dates being set.
The EU was unwilling to accept this result and with other nations formed a group of "pioneer countries" that promised to establish ambitious national or even regional goals to achieve global targets. The Johannesburg Renewable Energy Coalition (JREC) has a total of more than 80 member countries; the EU members, Brazil, South Africa and New Zealand amongst them.
In the European Conference for Renewable Energy in Berlin in 2004, the EU defined ambitious goals of its own. The conclusion was that by 2020, the EU would seek to obtain 20% of its total energy consumption requirements with renewable energy sources. Up until that point, the EU had only set targets up to 2010, and this proposal was the first to represent the EU's commitment up to 2020.
In 2009 the Renewables Directive set binding targets for all EU Member States, such that the EU will reach a 20% share of energy from renewable sources by 2020 and a 10% share of renewable energy specifically in the transport sector. By 2014 the EU realized a 16% share of energy from renewable sources with nine member states already achieving its goals.
