When it comes to conserving electricity, it is crucial for users to understand how much electricity is used by single appliances. However, the rather technical feed- back in pure numbers and intangible units of existing energy feedback systems is not appropriate for most users. To improve this situation, we present PowerPedia, a system that aims at providing action guiding feedback beyond pure consumption values. PowerPedia enables users to identify and compare the consumption of their residential appliances to those of others. It thus helps users to better assess their electricity consumption and draw effective measures to save electricity.
