With this workshop, co-organised with the Maltese Ministry for Energy, Enterprise and Sustainable Development, we explored policy, technological and practical approaches to fully realise the highly needed energy savings and achieve the emissions-reduction potential of the water-energy nexus.
Water and energy are highly interdependent (‘water-energy nexus’) and should be considered as such across all European Union policies. This would ensure the availability of Europe’s water resources, while supporting the EU energy and climate objectives, in particular those related to energy efficiency.
Energy is needed to abstract, distribute, heat, cool, treat and desalinate water. Water and wastewater sectors account for 3.5% of electricity use in the EU and that share is expected to rise over the next years. For municipalities, water and waste water facilities account for the largest consumption of electricity, representing 30-40% of local authorities’ total electricity bill.
Smart water management across the water sector as well as industrial, commercial, and residential water cycles can lead to significant energy savings. The key is to fully understand the energy-water nexus, its ability to generate water and energy efficiencies, and its contribution to deliver the ambitious goals of the European Green Deal.
The workshop featured:
- A keynote address from Miriam Dalli, Minister for Energy, Enterprise and Sustainable Development of the Republic of Malta
- An overview of the EU policy and regulatory framework related to the water-energy nexus by Veronica Manfredi, Director for Quality of Life, DG Environment, European Commission; and Robert Nuij, Deputy Head of Unit for Energy Efficiency, DG Energy, European Commission
- Case studies presentations by leading businesses to support current EU policy implementation and future policy and regulatory developments
- Q&A with the panelists
- Conclusions by Simona Bonafè, Member of the European Parliament and of the ENVI and ITRE Committees

Water-energy nexus and energy saving obligations: industry success stories
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.
