Fig. 5: Surplus or deficit of rooftop PV electricity generation to energy demand.
From: Mapping Europe’s rooftop photovoltaic potential with a building-level database
The map illustrates the estimated spatial balance between potential rooftop PV electricity generation and sectoral energy demand at 1 km × 1 km resolution across the European Union. Sectoral energy demand includes commercial and public services, households, agriculture and forestry and fishing, derived from the Energy Atlas dataset. Regions with positive values indicate a local PV electricity surplus (blue colours), whereas negative values represent a deficit relative to demand (red colours).
