Feedback on electricity consumption can help consumers save energy by providing them with better control over their usage. This paper explores which types of feedback are most effective in promoting energy conservation. A psychological model is presented to explain how and why feedback works. Key features of effective feedback include frequency, duration, content, appliance-specific breakdown, medium, presentation, comparisons, and integration with other tools. International studies suggest that frequent, long-term feedback with clear, appealing presentation and computerized tools is most successful. Sustainable electricity consumption is challenging because electricity is abstract, invisible, and not directly perceivable. It is used in various activities, making it hard for consumers to see the connection between their actions and energy use. Electricity conservation involves not only using appliances but also choosing them wisely. Consumers often receive little feedback on their consumption, making it difficult to manage usage effectively. Improving feedback on electricity consumption can help address these challenges. Current feedback is limited, as consumers are not informed about how or when electricity is used. Enhanced feedback, such as frequent, detailed, and visually appealing information, can help reduce consumption. Studies show that improved feedback can reduce electricity use by up to 20%. The EU has recognized the importance of feedback in energy efficiency policies. This paper reviews existing research on feedback and identifies key factors that influence its effectiveness. It aims to develop a theoretical understanding of how feedback works and to identify design features that can optimize its impact. The findings suggest that effective feedback should be frequent, detailed, and presented in an engaging manner to encourage sustainable electricity consumption.Feedback on electricity consumption can help consumers save energy by providing them with better control over their usage.
