To effectively address the challenges posed by the increasing share of the energy sector in global greenhouse effects, the domains of energy informatics and energy citizenship play a critical role. Energy informatics aims at using information systems and channels to reduce energy consumption. However, there is a realization that the challenges posed by global greenhouse effects cannot be catered to alone by the energy information systems. Therefore, there is a need for engaging human inhabitants to actively engage toward more sustainable means (i.e., energy citizenship) thus reducing the energy sector’s share in the global greenhouse effect. This paper presents a systematic literature review (SLR) after analysis of (n = 115) articles on the topic to identify (i) the themes considered in energy informatics and energy citizenship domains, and (ii) the interconnection between energy informatics and energy citizenship domains, (iii) energy information needs among stakeholders which establish a clear interconnect with energy citizenship. These identified themes and their interconnections are critical for energy researchers, policymakers, and energy businesses to identify relevant research topics, identify energy consumers’ needs, and create just energy transition policies. The paper additionally summarizes the gaps in the state of the art by mentioning the open research questions that arise due to the identified interconnection between energy informatics and energy citizenship.
