Changing user behavior with home electricity use to reduce and shift the demand on the electric grid
… or in terms of environmental emissions from non-renewable power plants? Would this appeal to their concerns about wastefulness and cause them to change their behavior with household appliance use? To test this question an experiment was designed, and multiple prototypes were built. The experiment …
