The Role of the Internet of Things in Enhancing Sustainable Urban Energy Systems: A Review of Lessons Learned from the COVID-19 Pandemic

Abstract

ABSTRACT The Internet of Things (IoT) has emerged as an indispensable technology enabling the efficient management of energy consumption and deployment of renewable energy solutions within urban energy systems. While urban energy systems can be made sustainable in both smart cities (SC) and traditional cities, the former provide a more advantageous environment for achieving sustainability thanks to advanced technology integration, data-driven decision-making, integration of renewable energy, as well as policy and infrastructure support. Across the globe, cities are evolving into SCs through the implementation of sustainable urban energy systems and adaptation to the latest IoT technologies. For them, advanced cutting-edge technologies such as digital twins, artificial intelligence (AI), Big Data, and IoT are all positioned to underpin the civic platform for new forms of a city that is simultaneously sustainable and prosperous. The COVID-19 pandemic brought about significant challenges, emphasizing the need for resilient and sustainable urban environments and demonstrating that IoT became a must for the modern cities in energy generation, transmission, and the efficient use of energy sources by cities. This bibliometric review focuses on the new role of IoT in the development of post-COVID sustainable urban energy systems. It demonstrates how IoT can help to efficiently manage energy consumption and to deploy novel renewable energy solutions in the cities using the experience from the two years of the COVID-19 pandemic. The article explores the role of IoT in the post-COVID urban energy development highlighting how the technology can contribute to sustainable urbanization. It employs the extended literature review including both 151 publications retrieved from the Web of Science (WoS) database selected based on the relevant keywords and the analytical tools based on Google Trends as well as the enhanced network dynamics VOSviewer v.1.6.15 software (the latter being frequently used for identifying the dominant trends in intersectoral bibliometric research). The findings stemming from this research can contribute to the clustering of the discussion of the strategies required for boosting SCs’ development and growth. Therefore, the results and outcomes can provide many useful insights for academics and stakeholders alike on the role of the IoT in the development of sustainable urban energy in post-pandemic cities.
