Solidarity and cohesion. CHALLENGE EUROPE Issue 22. Challenges and new beginnings: Priorities for the EU's new leadership, September 2014

In the past five years, the concept of solidarity has quietly lost much of its traction in the public discourse in Europe. Widely used at the time of the creation of the single market, the emergence of the common currency and during the EU's big bang enlargement of 2004-2007, it has recently become a more confused organising principle. The European system has been affected by growing levels of distrust, which has much to do with the way in which the euro zone crisis was tackled. In spite of massive resources having been mobilised to support countries in need, mutual accusations and discord have become ever more present in the EU's policy-making process.

A Roadmap to Enhanced Regional Energy Policy: Cooperation in South East Europe. CEPS Special Report, No. 134/April 2016

Regional Energy Policy Cooperation has now gained political traction in the EU as a tool to advance the EU’s energy objectives. Cooperation and coordination is meant to facilitate the convergence of markets and policies, so while the creation of one EU Internal Energy Market remains the goal, regional cooperation is the tool with which to achieve that goal. Cooperation could become the stepping-stone towards the completion of the Internal Energy Market within the European 2030 climate and energy framework and beyond.
