How to make the European Energy Transition work?

In the run-up to COP21 in Paris 2015, the Heinrich-Böll-Stiftung European Union organised a dinner debate at the sidelines of the UN Climate Summit in Warsaw to focus on Poland, Germany and France on how to make the energy transition work: How can an exchange between East and West help to increase understanding and to learn from each other about challenges and opportunities of the energy transition? And what is the potential for an increased bilateral – and European – cooperation in order to transform our energy systems including measures to increase energy efficiency?
