On 28-29 May 2018 Delegates to the IEA Experts’ Group on R&D Priority Setting (EGRD) held a workshop to gain further understandings of the issues of the energy-water nexus and to highlight best practices and opportunities. Technology experts from research entities, academia, and leading agencies across the world offered a wide range of perspectives and insights. The European Commission in Brussels hosted the event.
Experts from Europe, Japan and the United States shared best practice, highlighting areas for further research. Four presentations focussed entirely or in part on research activities of the IEA Technology Collaboration Programmes (TCPs). Contributions addressed a wide range of issues:
- Frameworks for international co-operation
- Governance and regulation
- Integrated management of natural resources
- The important role of technology – for both energy and water
- Data collection and analysis
Understanding the energy-water nexus and the implications for an integrated energy system is in the exploratory phase - we are beginning to understand the stress-points, trade-offs and synergies as well as direct and indirect benefits. The energy-water nexus provides a holistic approach to address the Sustainable Development Goals (SDGs), for which energy is part of the solution to the water scarcity and water is part of the solution to a low carbon energy system. Yet each sector uses different technologies and involves different stakeholders and institutions which makes policy- and decision-making very complex. In addition the issues of the energy-water nexus are broader and more complex, interrelated to land use, food, materials and eco-systems.
