Fog computing is distributed computing paradigm that brings computation and data storage closer to the sources of data for many IoT applications. In recent years, an alarming rate of increase in energy demand and the carbon footprint of fog environments has become critical issue. It is, therefore, necessary to reduce the energy consumption of these systems and integrate renewable energy use into fog computing environments. Renewable energy sources, however, are prone to availability fluctuations due to their variable and intermittent nature. In this work, we propose a new Fog computing framework for fog load shaping to match energy consumption with renewable energy availability using adaptive Quality of Service (QoS). The proposed framework, along with the optimization techniques, are tested on a real-world micro data center (Fog environment) powered by a solar energy source connected to multiple IoT devices. The results show that our proposed framework can offer significant brown energy usage reduction for Fog environments.
