Energy efficiency in the context of Industry 4.0

The aim of this paper is to identify, through a bibliometric analysis, how and which technologies, in the context of industry 4.0, are explicitly capable of promoting energy efficiency. The research was conducted on the Web of Science platform, using an algorithm with keywords of interest to the theme. As a result, a total of 67 articles were reached. Studies have been identified involving energy efficiency in the fields of industrial internet of things, wireless sensor networks, energy harvesting, cloud manufacturing, big data, artificial intelligence, additive manufacturing, and interdisciplinary research.
