Marta Victoria til #EUSEW19

The European Sustainable Energy Week (EUSEW) included a lot of interesting sessions and discussions relevant to the energy transition. Find below a list of those messages and reports which I found more relevant.

  • The Renewables 2019 Global Status Report by REN21 was presented. Worldwide capacities of renewables keep increasing. China reduced investment in 2018 was compensated by Europe and other regions. As a consequence, last year the renewable sector accounted for 11 million jobs.
  • Sector coupling is a hot topic. The electricity sector is increasing the renewable share but it only represents a small part of the energy system. Other sectors, such as Transport or Heating and Cooling, do not show the necessary decarbonisation trend. Specific targets and regulations are required to accelerate decarbonisation of those sectors.


  • Adaptation to climate change presents challenges and opportunities. For instance, climate change strengths the importance of the water-energy nexus. With more frequent droughts, renewable energy sources that do not require water, e.g., wind and solar PV, will be less impacted by climate change. The energy system in European countries will have few positive climate impacts but most of them will be negative (check the details on the report presented by European Environment Agency).


  • Many things are changing. The IRENA report Innovation landscape for a renewable-powered future presents a comprehensive map of the enabling innovations to achieve highly renewable shares, not only in the technology aspect but also regarding business models and market design.


  • Finally, the session in which I participated and where we presented the REInvest project. In this project Arhus University and Aalborg University are collaborating to model the transition towards a low-carbon European energy system, the challenges and opportunities and, in particular, the decarbonisation of Denmark energy system in this context (find the slides here).
