The European Union has the unique opportunity to lead a just and fair energy transition. As geopolitical tensions escalate and the climate crisis deepens, the EU must seize this moment to redefine its energy and industrial policies, focusing on resilience, independence and sustainability. Energy efficiency, often and rightly so-called Europe’s “first fuel,” is more than just a technical fix or policy goal—it’s a powerful enabler of systemic change, laying the groundwork for a cleaner, more equitable, more competitive and secure future.

The case for energy system efficiency

Energy System Efficiency (ESE) offers a holistic approach to optimising energy use across all sectors and technologies, from generation to consumption. It is about more than saving energy; it is about reimagining the energy value chain, for the better. An ESE framework fosters integration between sectors, enhances industrial competitiveness and strengthens energy security. This systemic approach contrasts with the fragmented model that has dominated for centuries, where isolated improvements fail to achieve transformative change.

For Europe, adopting ESE means addressing critical challenges, such as dependency on external energy sources, affordability of energy costs and the volatile pricing of fossil fuels. It means transforming our energy infrastructure to support decentralised, renewable-driven grids that are flexible, interconnected and most importantly efficient.

Why breaking down silos matters

Take the example of buildings, responsible for 40 percent of the EU’s energy consumption. By integrating energy renovations with renewable technologies and electrified solutions, buildings can shift from being passive consumers to active participants in the energy system. Such integration reduces peak demand, stabilises the grid and lowers energy bills for consumers. A siloed approach could lead to suboptimal outcomes, such as merely shifting energy use from one sector to another without reducing and optimising overall consumption. Instead, Europe must embrace cross-sector collaboration, aligning policies, technologies and investments to achieve true systemic efficiency.

Collaboration: the key to success

An energy-efficient future requires more than technological innovation; it demands close collaboration. Policymakers must produce regulations that encourage system-wide efficiency. Industries must invest in energy efficiency improvements, digitalisation, flexibility and renewable integration. Civil society must advocate for a just transition that leaves no one behind.

Sector integration is pivotal. For instance, excess heat from industrial processes can be repurposed for district heating systems, energy renovations can reduce stress from the grids and smart grids can balance supply and demand across sectors. This interconnected approach not only optimises energy use but also creates economic opportunities, from green jobs to local innovation hubs.

The overlooked connection: the water-energy nexus

One critical but often overlooked aspect of energy system efficiency is the water-energy nexus. Recognising the interdependence between water and energy resources is crucial, yet it remains underaddressed in many policy frameworks. Approximately 10 per cent of the world’s freshwater withdrawals are attributed to the energy sector. Water is essential for energy generation, from cooling power plants to hydropower, yet water scarcity – caused by climate change, irresponsible consumption and inefficient management – poses a growing threat to both citizens and industries. By prioritising energy efficiency, we can alleviate pressure on water resources, fostering resilience in both energy and water systems.

However, progress remains slow and awareness is still limited. Without concerted action, water scarcity could jeopardise the very foundations of our energy infrastructure, putting both citizens and industries at significant risk. This challenge highlights the urgency of integrating water considerations into energy planning, not as an afterthought but as a cornerstone of a resilient and sustainable energy future.

Win-win for all: social and economic gains

Energy efficiency is not just an environmental necessity; it is a social and economic imperative. It lowers energy costs for households, alleviating energy poverty for millions across Europe. It creates jobs in the construction, manufacturing and tech industries. And it fosters energy independence, a cornerstone of EU competitiveness and resilience.

For industries, enhanced energy efficiency translates to reduced operational costs and improved global competitiveness. For citizens, it means cleaner air, better health outcomes, and a higher quality of life.

A call to action

Europe cannot afford to delay. The technologies, frameworks and policies required to attract the much-needed public and private investments for an energy-efficient future are available. What we need is the political will and societal commitment to deploy them at scale.

Breaking down silos and prioritising energy efficiency at the system level is a rational pathway to a competitive, resilient, just and sustainable Europe. Let’s be smart and take a chance now to avoid future regrets.
