Today, the European Commission has adopted its strategy for a European Energy Union. Energy is used to heat and to cool buildings and homes, transport goods, and power the economy. But with ageing infrastructure, insufficiently integrated markets, and uncoordinated policies, our consumers, households and businesses do not reap the full benefits of increased choice and lower energy prices. It is time to complete the single energy market in Europe. By unveiling its strategy to achieve a resilient Energy Union with a forward-looking climate change policy, the European Commission delivers on a top priority set out in President Juncker's political guidelines.
