The Static! project, developed by the Interactive Institute, aimed to
investigate how interaction design could increase users awareness of how
energy is used in order to stimulate changes in user behaviour. Several
products were prototyped as part of the Static! project, one of which
was the Power Aware Cord.
"The ‘Power-Aware Cord’ is a re-designed electrical power
strip in which the cord is designed to visualize the energy rather than
hiding it. The current use of electricity is represented through glowing
pulses, flow, and intensity of light. This enables the user to visualise
and reflect on the energy consumption of household devices.
The Power Aware Cord has been patented and is now
commercially available in Europe. For more information visit:

You can find further examples of products designed to raise
awareness of energy use on the Static! website
