Collective Power employs a new type of human-computer interaction by visualizing data in a socially and psychologically aware way. The typical display of energy usage where a customer is informed, via various data visualization means, of their own use, is broadened to include a public element. The information for physically adjacent buildings is posted on nearby lamp posts in a vertical meter-like light display that can be viewed for long distances on the urban scale at night. The poles read a comparison to a global standard so that the energy collective participants can tell their collective standing in energy use, percapita, at a glance. More detailed information about individual participants in the energy collective is provided through an iPhone application accessible through a projection from each pole, enabling members of the public and the collective to improve their energy use habits.
