**5.3 Cloud computing**

Cloud computing can enhance the scalability and reliability of IoT-enabled energy management systems. By providing on-demand access to computing resources and storage, cloud computing can help to process and analyze the large amounts of data generated by IoT devices, enabling more effective energy management [14]. Additionally, cloud computing can help improve energy management systems' reliability and resilience by providing redundant storage and computing resources (**Figure 6**).

Cloud computing offers scalable computational resources to handle the dataintensive demands of IoT-enabled energy management systems. The cloud provides the necessary infrastructure for processing and analyzing the massive amounts of

data generated by IoT devices in real-time. This enables continuous monitoring, rapid response to changing conditions, and data-driven insights for better decisionmaking. Moreover, cloud-based solutions enhance system reliability and resilience by offering redundant storage and computational resources. The ability to remotely access and control energy management systems through the cloud empowers users to monitor and adjust energy consumption even from remote locations, contributing to overall efficiency.

**Figure 7** shows the collaboration between cloud computing and the Internet of Things (IoT) for energy management optimization. Cloud computing is depicted as a central hub, offering scalable resources and storage. This supports real-time processing of data from IoT devices, ensuring continuous monitoring and informed decisionmaking. IoT devices gather data via sensors, transmitting it wirelessly to the cloud for analysis. This synergy enables efficient energy management, thanks to the cloud's computational capacity.

Examples of how these solutions can be used to improve energy management efficiency and effectiveness include:

Using AI algorithms to optimize energy consumption in buildings by analyzing data on occupancy patterns, weather conditions, and energy usage to adjust heating, lighting, and ventilation systems.
