Since the problems caused by the global climate crisis threaten the lives of all kinds of living creatures, it has brought to the agenda the need to reduce the greenhouse gas emissions that cause it as quickly as possible. Reports published by international organizations and researchers draw attention to the urgent need to use renewable energy sources instead of fossil fuels in energy systems and digital technologies to ensure energy efficiency and control to reduce greenhouse gas emissions. Emphasizing the necessity of using digital technologies in energy systems by highlighting their impact on reducing greenhouse gas emissions causes digital technologies to be the leading actor in solving the global climate crisis. On the other hand, studies show that digital technologies have more challenges than expected. However, these studies, which are few, do not attract enough attention. Being aware that digital technologies in energy systems provide challenges and opportunities will lead to more rational investments in digital technologies. Therefore, this study aims to review articles that evaluate the opportunities and challenges provided by digital technologies in energy systems and contribute to the literature by presenting a survey that examines them together. For this reason, 21 current studies examined and determined that challenges should be taken seriously in addition to the opportunities provided by digital technologies.
