Power Point, a concept device designed by Jon Ardern a student of the Royal College of Art, aims to "change patterns of power use by creating awareness of how much power individual appliance draws. Leading users to re-evaluate how they consume power"[1]

Each power socket would feature a simple display showing the amount of power being consumed at any given time in a very clear, visible and direct way.

Utilising a technology called X10, which enables communication among electronic devices, information about patterns of power consumption would be sent through the existing power cables to a central database.
