This study aims to explore the application of computer energy-saving systems in employees' computers and conduct a technical analysis of their impact on energy consumption and the environment. While computer energy-saving systems have demonstrated significant energy-saving effects in practical applications, they also present some limitations, such as the challenge of balancing energy-saving effectiveness and user experience. In this research, we conducted an empirical study in a specific company in China by installing computer energy-saving software on employees' computers and collecting energy consumption data in different work states to derive energy-saving models and data. After a 7-day observation period, we found that the computer energy consumption of employees in the eastern region, where the computer energy-saving system was implemented, was significantly lower than that of employees in the northern region, where the system was not used. Furthermore, we assessed the environmental values and energy-saving behaviors of employees in both regions to investigate the impact of the computer energy-saving system on employees' individual energy-saving awareness. Conducting independent sample t-tests on the collected data, we observed that employees in the eastern region exhibited significantly higher environmental values and self-reported energy-saving behaviors compared to those in the northern region. This indicates that the application of the computer energy-saving system not only reduces computer energy consumption but also stimulates employees' energy-saving awareness and behaviors to some extent. These discoveries provide crucial technical support for companies and other organizations to develop targeted energy-saving and environmental protection strategies while promoting sustainable development and environmental conservation efforts.
