This paper discusses power challenges caused by an explosion in data driven application at the Edge of IOT. How technology, power management techniques, machine learning (AI) and energy recycling are evolving to do more computing at the Edge of IOT to solve Power, Data, Communication and Latency issues. The paper will show how innovation is needed to bring different topics together to provide an optimal solution for the power challenges ahead. A use case with biometric security at the edge will be discussed
