Abstract
With the emergence of new technologies and policies to transition to clean energy, the household energy consumption sector is also changing. In response to policy, environmental, and technical changes, researchers need to find out what significant issues are related to household energy consumption, and comprehensively analyze which issues are likely to attract attention in the future to contribute to research in the household sector. Based on the abstracts of academic papers published between 2011 and 2020, this study uses probabilistic topic modeling to increase understanding of academic issues in the household energy consumption sector and statistically reviews changes in issues over time. As a result of the analysis, topics related to digitalization and renewable energy, such as microgrid system, smart home, residential solar power generation systems, and non-intrusive load monitoring (NILM), belonging to Strong signals, are being actively studied. Weak Signals, which can attract attention in the future, are included in discussions on coal energy consumption, air pollutant emissions, energy poverty, and energy performance evaluation. The analysis results show that carbon neutrality, such as decarbonization and fossil energy consumption reduction, is expanding to research in the household energy consumption sector.
Highlights
Household energy consumption accounts for a large portion of total energy consumption
The household energy consumption sector is changing due to the emergence of the Internet of Things (IoT) and artificial intelligence (AI) technology to manage household energy demand, the promotion of energy efficiency policies to transition to clean energy, and the increase in single-person households
Over the past 10 years, research topics related to household energy consumption have mainly focused on expanding the use of smart and clean energy technologies in the household sector and discussing whether the benefits provided by the technologies can be enjoyed
Summary
Household energy consumption accounts for a large portion of total energy consumption. Household energy consumption accounts for approximately a third of the world’s primary energy demand and significantly impacts the environment [1]. Environmental, and technical changes, researchers are trying to find ways to reduce household energy consumption by improving energy efficiency and predicting energy consumption through new technologies. For researchers to contribute to the household energy consumption sector in the future, a comprehensive analysis is needed on what significant issues related to household energy consumption are increasing, what issues are decreasing, and which issues are likely to attract attention in the future. Researchers can find out what research is currently needed concerning household energy consumption and explore appropriate research topics for each sector, such as policy, environment, and technology. The main research questions in this study are as follows
