  We propose a novel self-sustained ecosystem for energy sharing in the IoT
environment. We leverage energy harvesting, wireless power transfer, and
crowdsourcing that facilitate the development of an energy crowdsharing
framework to charge IoT devices. The ubiquity of IoT devices, coupled with the
potential ability for sharing energy, provides new and exciting opportunities
to crowdsource wireless energy, thus enabling a green alternative for powering
IoT devices anytime and anywhere. We discuss the crowdsharing of energy
services, open challenges, and proposed solutions.
