Ahmed Olabisi Olajide · Advances in environmental engineering and green technologies book series · 2025
The rise of Internet of Things (IoT) devices, fog computing, and blockchain technologies has reshaped modern distributed systems, but energy consumption poses a critical challenge. This chapter explores energy patterns in IoT, fog, and blockchain ecosystems, emphasizing the importance of efficiency. It discusses the interplay between these systems, energy usage in IoT devices, network protocols, cloud and edge computing impacts, energy needs in fog computing, and challenges in distributed fog nodes. It also examines the energy implications of blockchain consensus mechanisms like proof-of-work and proof-of-stake, sustainable protocols, and energy-efficient strategies such as machine learning. Real-world examples highlight successful energy-efficient deployments in smart cities and green energy systems. The chapter concludes by stressing the need for energy-efficient practices in designing and implementing these technologies for a sustainable digital future.
