Increasing energy efficiency is one of the key elements for reaching national and international targets to reduce climate change. Energy policy in Germany is increasingly designed by EU energy policy. Therefore, it is of basic importance to actively participate in the energy policy processes on EU level and to technically contribute to them. However, on EU level one is often confronted with other challenges regarding strategic possibilities and political instruments. Currently in the field of energy efficiency only little progress regarding possibilities and reaching legal targets can be seen. In June 2011 the EU commission therefore presented a proposal for a European energy efficiency directive. This directive came into force on 5 December 2012 and has to be implemented into national law until 5 June 2014. Until end of June 2014 the EU commission has to review the progress made due to the directive in reaching the EU target of increasing energy efficiency by 20% until 2020. In case of deviation from the target path further measures would be necessary. In this project the mix of measures and instruments on EU level and in certain Member States will be analysed. Contributions and interactions of certain measures will be analysed quantitatively and qualitatively; good practices will be identified. On this basis conclusions will be drawn regarding the achievement of energy efficiency targets for 2020 and regarding further potentials for 2030. In three workshops taking place in different Member States (interim) results will be presentend and discussed.
