Abstract: The issue of energy efficiency is facing a serious global challenge, and we must optimize energy consumption for the survival and development of mankind. In the paper, various schemes for energy saving in smart homes are categorized and explained. The effect of each energy saving scheme is compared, categorized, and summarized. Energy-saving solutions for smart home systems, home energy management systems, and various other solutions that can effectively realize energy saving are described and compared. Solutions that combine various algorithms with smart homes to achieve energy saving are also discussed. This paper provides a critical overview of various energy saving schemes. The problems of the various schemes are discussed. It is important to consider not only the energy consumption but also the comfort of the users and their safety. The introduction also confirms the importance of education about energy usage for the users. The overview provides some useful suggestions for the research and development of optimized energy management systems applicable to homes, buildings, etc. Readers could use this article to get an idea of the solutions and ways of energy management in smart homes. It is hoped that energy and power saving can be better carried out in the future to protect the environment and reduce carbon emissions.
