The control device acquires information regarding an event held within a certain area, and based on the acquired information, the power supply has the function of supplying power to electronic devices used by the user from among multiple locations within the area. The control unit includes a control unit that determines a location to dispatch the mobility and performs processing to dispatch the power supply mobility to the determined location.

System and method for to reduce ground surface temperature for an area using a fleet of drones is described. Each drone in the fleet comprises multiple motors, a body with a first and second end, and a surface equipped with sunlight management films. These films are designed to reflect sunlight and convert it into electricity for charging onboard batteries. A Ground Control Station (GCS) is communicatively coupled to the fleet, enabling synchronized transmission of a flight program and a sunlight management program. These programs are designed to track the geoposition of the drones and align their operations with real-time environmental data. The GCS is further integrated with an environmental sensor for measuring ground surface temperature and sending input data for temperature tracking.
