An Energy-aware Survey on ICT Device Power Supplies

This analytical report highlights that standardizing efficiency characteristics could reduce energy consumptions and greenhouse emissions of external power supplies by up to 50 per cent. It underlines opportunities to achieve further reductions in e-waste, energy use and greenhouse gas emissions by widening the range of ICTs supported by power adaptors and standardizing design parameters able to optimize these adaptors’ eco-efficiency. It raises awareness on the contribution of innovative technology to sustainability. It presents the results of a study of 300 available adapters, both for ICT and non-ICT use. The report suggests that an environmentally friendly design could result in savings of more than 30 per cent of the materials used to build the devices. Finally, this report focuses on efforts for improving energy efficiency wherever possible by building a responsible world through ICT-enabled transformation.
