G20 Energy Efficiency Action Plan: Networked Devices

In November 2014, G20 Leaders launched the 'Energy Efficiency Action Plan' comprising six areas for collaboration, including networked devices.

Although network connectivity increases opportunities for energy management, such as controlling the temperature setting of ones air conditioner by smart phone, it also adds to energy consumption as appliances use 'network standby' power just to remain connected to the network.  As shown in the joint IEA/4E publication, "More Data, Less Energy", the current annual standby power consumption of networked devices is over 600 billion kilowatt-hours, which is greater than Canada's 2011 annual electricity consumption.  With up to 50 billion devices forecasted to be connected to networks by 2020, global standby power consumption is projected to nearly double by 2025.

In response, the G20 Task Group has brought together 350 governments and private sector organisations as part of the Connected Devices Alliance (CDA). Led by the United Kingdom, the IEA, Canada and The Netherlands, the CDA provides a unique forum for dialogue between industry and government representatives on an issue that is rapidly gaining global significance.

Major projects undertaken by the CDA include:

  • The CDA Centre of Excellence provides a source for authoritative information on energy saving opportunities and best practices that can be attained by networked devices and the networks within which they operate - https://cda.iea-4e.org/
  • The CDA Principles for Energy Efficient Connected Devices; these voluntary principles provide an energy efficiency blueprint for designers of products, protocols and policies in the field of networks and networked devices - https://cda.iea-4e.org/cda-principles

4E has provided the Secretariat function for the CDA since its inception, and this is now done through the direct support of EDNA.
