City energy consumption. Together with the air quality
monitoring service, an urban IoT may provide a service
to monitor the energy consumption of the whole city, thus
enabling authorities and citizens to get a clear and detailed
view of the amount of energy required by the different services
(public lighting, transportation, traffic lights, control cameras,
heating/cooling of public buildings, and so on). In turn, this
will make it possible to identify the main energy consumption
sources and to set priorities in order to optimize their behavior.
This goes in the direction indicated by the European directive
for energy efficiency improvement in the next years. In order
to obtain such a service, power draw monitoring devices must
be integrated with the power grid in the city. In addition, it
will also be possible to enhance these service with active
functionalities to control local power production structures
(e.g., photovoltaic panels).
