Abstract: In order to provide sufficient and low-cost energy to sustain economic growth and living standards, innovation and development of alternative energy sources are required. Over the past decade, the demand for high-rate multimedia wireless communication services has increased dramatically with the popularity of mobile devices.The need for media rich input/output computation and communication forces mobile users ta charge their devices more often. On the other side , service providers have been adding more and more base stations (BSs) to meet a higher service demand. A large portion of the service providers' operational costs is due to energy consumption of the wireless systems for both mobile users and service providers. This Plenary Lecture deals with energy efficiency approach from wireless networks to potential applications toward 5G systems. Recently, 5G cellular networks are becoming the most active research area in wireless communications.The 5G mobile network is required to have tremendous spectral efficiency (SE) and energy efficiency (EE) improvement simultaneously. As a result, SE, EE, and cost efficiency have been used as three obligatory 5G evaluation metrics. In general, joint energy and communication cooperation is more complex than energy or communication cooperation only. Joint energy and communication cooperation can maximally save cost by applying both energy cooperation on the supply side and communication operation on the demand side. For the realization, the BSs should share the energy information by using the two-way information flow supported by the smart grid. The communication information is exchanged through the back haul connections. As for 5G networks, the primary goal is to satisfy a variety of users needs in a more energy efficient manner. The question often arises will be where the energy can be further saved and what available information in the network can be exploited. Starting with energy saving approach, cellular networks with energy and communication cooperation are pointed out. Next, recent advances in energy efficient networks and their application in a new generation of mobile communication- the fifth generation (5G) are presented and discussed. Finally, the corresponding challenges are emphasized.
