#### Industrial Training Based on Virtual Reality
It was concluded that interactivity, developed environments, and fault feedback contribute to the learning process and development of skills for understanding and managing energy systems. [PERSON] et al. [PERSON] et al. (2018) clarify the functional reRequirements of a VR system and propose a hierarchical and modular design plan. This proposal allows to efficiently solve the virtual training process in the field of industrial maintenance. The usefulness of this design is focused on generating training areas with more opportunities and available at any time. [PERSON] et al. detail a virtual training system for operators in the field of maintenance and service of robotic stations [PERSON] et al. (2018). Oculus Rift VR glasses, a computer with powerful graphics capabilities,and RobotStudio software were used. Within the developed environments, scenarios were created to detect failures, make repairs, and provide maintenance service. The methodology used began with explaining the characteristics of a faulty robotic station, the operation of the calibrating robot, and the process to replace the gear oil. The fact that, in recent years, the main oil and gas companies worldwide have opted for virtual training systems focusing on sustainable development is exposed by [PERSON] et al. [61]. Besides, they are developing a VR system that consists of three stages: (i) VR documentation and design, (ii) testing and evaluation of the effectiveness of this type of technology for the extraction and installation of heat pipes in the gas industry and oil, and (iii) comparison between process times during the execution of an immersive environment. [PERSON] et al. [62] establish that the application of VR systems in the logistics area is of great importance, since, even though there is little research in this area, its potential use allows for updating conventional teaching methodologies, interactively training users, and optimize the way processes are displayed. All pf this for logistics professionals to consider the best options when making a decision, saving money, time, and reducing the risk that the industry represents. The development and improvement of four VR scenarios, for maritime security, called Immersive Safe Oceans, which can be used within the academic field as well as in the professional world, is in charge of [PERSON] and [PERSON] [63]. The central idea of this work is to develop environments that test users and train them in order to make crucial decisions in various situations (i) within the command bridge, (ii) machine room, (iii) crane management and, (iv) fires. [PERSON] et al. [64] propose a training tool focused on technicians and beginners for monitoring water discharge in open-channel flows. This system was developed in the Unity 3D graphics engine in conjunction with the Oculus Rift HMD. To evaluate this system, a survey of 18 questions was applied, which aimed to determine the quality of the system, interactivity, performance, impact, and achievements. The results showed that the system is robust and allows for holistic training for all types of users. Finally, [PERSON] et al. [65] provide a study on educational courses that are linked to VR. This research identifies the current state of VR within the industry and estimates the VR content taught by prestigious institutions. As a result of these analyzes, an educational model was designed combining the needs of the industrial world with the knowledge and tools of the academic world. This model was implemented in a specialized course for VR developers, whose launch was in 2018 with the support of institutions dedicated to information technology. The training consisted of 960 h for 27 apprentices, of whom 21 were men and six were women. This selection criterion was used while taking into account the rate of employment and entrepreneurship that this technology offers, besides, the interest of people in the development of digital tools and their ability to understand in the software branch was considered.
