When designing wireless communication systems (WCS), spectral efficiency (SE)\nhas been the main design performance metric. Recently, energy efficiency (EE)\nis attracting a huge interest due to the massive deployment of power limited\nWCS such as IoT devices, and stringent environmental concerns. For this reason,\nmany works in the literature focused on optimizing the EE and highlighted the\nEE-SE relationship as a trade-off (meaning that increasing one decreases the\nother). In this article, after introducing the EE metric, we highlight a new\nperspective of the EE-SE relationship based on energy-efficient power control.\nIn particular, we give insights about the EE-based performance of various\ntransmission technologies and its impact on 5G future design. Via numerical\nresults, we show that the corresponding power scheme allows an increase of both\nthe SE as the EE with no trade-off. Finally, we present relevant open research\nproblems.\n
