Letter to the College of Commissioners: “Energy efficiency first” in the Energy Union
On behalf of the European Alliance to Save Energy (EU‐ASE), we are writing to express our full support for the creation of the Energy Union and to encourage you to place energy efficiency firmly at the forefront of its development and operation.
In the same way that it would be smart to fix any leaks in a race car fuel system before upgrading the size of its fuel pump, so it is necessary to address existing inefficiencies in European energy use before attempting to upgrade its distribution infrastructure and tackle other measures to strengthen and modernise its energy system. Doing so will help to ensure that the benefits of the other measures are maximised and that funds spent in their support are leveraged to yield strong returns.
Simply put, a top‐priority focus on energy efficiency will set the stage for the success of the Energy Union, and to neglect its importance is to risk dooming the project from the outset.
So preeminent is “Energy Efficiency First” among the pillars of the Energy Union.
In a fast-changing political and economic environment, 2025 was a year of continued efforts to strengthen security, stability, and competitiveness for European businesses.
Throughout the year, our work demonstrated that energy efficiency is not only essential to achieving climate goals, but also a key driver of innovation, energy independence and sustainable long-term growth across Europe.
Strong engagement with policymakers, combined with the successful organisation of the 4th European Energy Efficiency Day, highlighted the importance of collaboration and dialogue in advancing shared objectives. Partnerships across sectors and institutions remained central to delivering impact and shaping effective energy policies.
Looking ahead to 2026, we will intensify our efforts to secure the regulatory certainty that can accelerate the energy transition, while providing businesses with the investment confidence they need and strengthening Europe’s competitiveness.
