Fig. 10From: A comparison of clustering methods for the spatial reduction of renewable electricity optimisation models of EuropeNormalised mapping of optimal capacities according to equation (12): The x-axis reflects the estimated optimal capacity of a the low resolution model \({\hat{G}}_{c,s}\), while the y-axis displays the totalised optimal capacities of the high-resolution model. The two considered technologies wind and solar are outlined using different colors. A linear fit to the respective data is added to the plots.
