Leaving rechargeable electrical devices plugged in too long wastes energy and can shorten their battery life, so industrial design students John Lee, Soyoung Bae and Sam Sauceda developed E3: Energy Efficient Electricity, a monitoring and controllable energy system that won the gold award and $2,000 at the 2012 International E-Waste Design Competition.
The event is part of the Sustainable Electronics Initiative (SEI) at the University of Illinois at Urbana-Champaign.
E3 allows power to be turned off to a charger, even remotely through a smartphone app, eliminating overcharging and phantom energy use that occurs when devices are plugged in and draw power even when not in use. Continued use of the E3 can reduce energy consumption and costs to consumers, the students explained in their presentation.
