The green paper calls for a European energy grid code, a priority European interconnection plan, a European energy regulator and new initiatives to ensure a level playing field between member states. The paper states that only fully competitive internal energy markets can provide EU citizens with low prices and energy security – and to achieve this aim competition rules must be rigorously enforced.

Other measures include investment in renewable energy sources and an action plan on energy efficiency, which will identify the measures necessary to save 20% of the energy that the EU would otherwise use by 2020. The paper also stresses the need for a common external energy policy for dealing with external suppliers such as Russia and a mechanism in place for responding to emergency supply situations.

The energy challenges of the 21st century require a common EU response. The EU is an essential element in delivering sustainable, competitive and secure energy for European citizens. A common approach, articulated with a common voice, will enable Europe to lead the search for energy solutions, underlined European Commission president Jose Manuel Barroso.

The call for unity comes at a time when several European utility mergers are causing consternation among member states, with a number of concomitant arguments raging between countries over protectionism and government interference. The paper will be presented to the EU leaders at their summit in June 2006.
