In 1997, in reaction to the Kyoto Protocol, the EU introduced non-mandatory targets for the RE share of total energy consumption for Member States. In 2006, the European Commission issued the Green Paper: A European Strategy for Sustainable, Competitive and Secure Energy. This asked Member States to implement a European energy policy built on three core objectives: 0 sustainability - to actively combat climate change by promoting renewable energy sources and energy efficiency, ii) competitiveness - to improve die efficiency of the European energy grid by creating a truly competitive internal energy market, and iii) security of supply - to better co-ordinate the EU’s supply of and demand for energy widiin an international context.
