In recent years, the global use of online video services has increasedrapidly. Today, a manifold of applications, such as video streaming, videoconferencing, live broadcasting, and social networks, make use of thistechnology. A recent study found that the development and the success of theseservices had as a consequence that, nowadays, more than 1% of the globalgreenhouse-gas emissions are related to online video, with growth rates closeto 10% per year. This article reviews the latest findings concerning energyconsumption of online video from the system engineer's perspective, where thesystem engineer is the designer and operator of a typical online video service.We discuss all relevant energy sinks, highlight dependencies withquality-of-service variables as well as video properties, review energyconsumption models for different devices from the literature, and aggregatethese existing models into a global model for the overall energy consumption ofa generic online video service. Analyzing this model and its implications, wefind that end-user devices and video encoding have the largest potential forenergy savings. Finally, we provide an overview of recent advances in energyefficiency improvement for video streaming and propose future researchdirections for energy-efficient video streaming services.
