The energy consumption still becomes a worldwide issue. A study measuring consumption in one of the universities in United States revealed that ICT equipment accounts for more than 70% of the baseline electricity load. With the development of technology, people can persuade others to conserve energy through direct interaction or human-computer interaction or computer-mediated communication, for example blog, email, social network, etc. In this thesis, we designed a six-week field trial to monitor computer-energy saving behavior, provide web application which employs social feedback comparison strategy and investigate its effectiveness to eight (n=8) students in university. Besides a quantitative analysis of the electricity measurement, a feedback questionnaire was deployed to give some insights. The main findings were; ranking pop-up notification as reminder was considered better feedback comparison rather than real-time consumption, neighbour comparison, and history comparison; the combination of social feedback comparison strategy with reward and tips were most powerful to motivate students towards computer energy-saving behaviour. The commitment and consistency of participants in implementing tiny habits to change their behaviours are important in forming long-term habits.
