Students in the residence halls have no clue how much electricity they are using. As a result, they are less active in energy saving.
Watty the Energy Monster is a mobile application that tracks the energy usage.
With the co-existing technology that gives the user the real-time feedback on his/her energy use, the app visualizes the information in a fun way. The app reveals the energy monsters that dwell in the student's room, and by seeing a number of Watties, the user becomes aware of how much energy he/she consumes. Also, a competition with his/her friends make them cut back even more.
