Guest Editorial Special Section on Energy Informatics for Green Cities

The nineteen articles in this special section focus on energy informatics, a new and emerging nterdisciplinary research field. The main goal is to tackle the future global warming, energy crisis, and climate change challenges by exploiting advanced information and communication (ICT) theories and tools to address energy-related problems. The scope of energy informatics includes the next-generation communications, networking, computing, sensing, and control technologies (e.g., big data, machine learning, 5G, cloud computing, and fog computing); and their applications in the energy sectors (e.g., smart cities, smart grid, electric vehicles, and PV systems).
