  This paper explores the role of energy-saving technologies and energy
efficiency in the post-COVID era. The pandemic meant major rethinking of the
entrenched patterns in energy saving and efficiency. It also provided
opportunities for reevaluating energy consumption for households and
industries. In addition, it highlighted the importance of employing digital
tools and technologies in energy networks and smart grids (e.g. Internet of
Energy (IoE), peer-to-peer (P2P) prosumer networks, or the AI-powered
autonomous power systems (APS)). In addition, the pandemic added novel legal
aspects to the energy efficiency and energy saving and enhanced inter-national
collaborations and partnerships. The paper highlights the importance of energy
efficiency measures and examines various technologies that can contribute to a
sustainable and resilient energy future. Using the bibliometric network
analysis of 12960 publications indexed in Web of Science databases, it
demonstrates the potential benefits and challenges associated with implementing
energy-saving technologies and autonomic power systems in a post-COVID world.
Our findings emphasize the need for robust policies, technological
advancements, and public engagement to foster energy efficiency and mitigate
the environmental impacts of energy consumption.
