Editorial special issue: Holistic transition of urban systems towards positive and resilient energy areas incorporating renewable energy generation

The transition of existing cities towards low carbon areas is a challenging task. The planning of energy systems on short and medium time scales is a major concern for decision makers. The analysis of possibilities and directions for urban development should focus on the integration of renewable energy sources within urban boundaries, considering their structure, location, availability, possibility for grid support, and their integration with energy storage systems and electric vehicles. This special issue presents the original results obtained by researchers focusing on various challenges of transition of urban systems towards positive and resilient energy areas with renewable energy sources.
