In this project, CyI will further develop and considerably enhance the CLEWs (Climate-Land-Energy-Water) Integrated Assessment Model. Specifically, CyI will develop a CLEWs-EU aggregated regional model, in which the EU will be represented as a single node; develop a CLEWs-EU disaggregated model, in which the level of spatial resolution will extend to the member state  level; adopt a more detailed temporal resolution by breaking down the model to at least 12 time-steps, which will consist of three seasons and four typical day-parts within each season to capture both peaks in demand, as well as variability in renewable energy availability; and enhance the model’s technological detail to increase the options that will make net-zero emission pathways technically feasible.
