Energy-aware solutions and approaches are becoming broadly available as energy concerns is becoming mainstream. The usage of computers and other electronic devices (e.g., smartphones, sensors, or digital equipments) is increasing, thus impacting the overall energy consumption. Reducing the energy consumption of connected devices and computers requires a comprehensive view of the different layers of the system. Sensors and actuators, used to monitor energy consumption and modify devices' options, need to be controlled by intelligent software. We propose an approach that adapts the software components and hardware param- eters in an autonomous manner.
