The article by Corinna Fischer explores the potential of improved feedback on household electricity consumption as a tool for energy savings. It presents a psychological model to explain how feedback works and identifies key features that enhance its effectiveness, such as frequency, duration, content, breakdown, presentation medium, comparisons, and combination with other instruments. The paper reviews international experiences to find empirical evidence for the most successful feedback strategies, suggesting that frequent and long-term feedback, appliance-specific breakdowns, clear and appealing presentations, and computerized interactive tools are particularly effective. The article also discusses the challenges of promoting sustainable electricity consumption, highlighting the abstract, invisible, and untouchable nature of electricity, which makes it difficult for consumers to perceive and control their usage. Despite these challenges, improved feedback has shown significant potential in reducing consumption, with some studies indicating up to a 20% reduction. The EU's 2006/32/EC Directive on energy efficiency further supports this approach by mandating informative billing and feedback. The article aims to provide a more theoretically grounded understanding of feedback's effectiveness and to identify the design features that contribute to its success.The article by Corinna Fischer explores the potential of improved feedback on household electricity consumption as a tool for energy savings.
