G20 Energy Ministers agreed to take the lead in promoting energy efficiency and adopted the G20 Energy Efficiency Leading Programme (EELP) at their meeting in Beijing on 29-30 June 2016.

Also highlighted was the “significant progress in voluntary international collaboration coordinated by IPEEC in the six key areas of Vehicles, particularly heavy-duty vehicles, Networked Devices, Finance, Buildings, Industrial processes, and Electricity Generation.”

In their final Communiqué, Ministers also noted the importance of energy collaboration within and beyond G20 countries for tackling common energy challenges and shaping a sustainable low GHG emission energy future. 

These messages will be taken to the G20 Summit on 4-5 September 2016. Germany will take over the G20 presidency in 2017.

Government and industry participants met at the International Energy Agency (IEA) in Paris on 19-20 May to discuss the CDA’s current progress and future activities. 

In his opening address, IEA Deputy Executive Director Paul Simons noted the strong support from industry and governments for this unique international collaboration on the important topic of connected devices. 

This has already resulted in substantial progress on key CDA projects, such as the Centre of Excellence, the CDA Voluntary Principles, Energy Aware Devices and Intelligent Efficiency (see articles below).

A global review of current and planned measures described the growth in all types of policies associated with networked devices, highlighting the need for international collaboration to share information and seek closer alignment.

The worldwide network standby energy consumption of devices used for Smart Lighting, Home Automation, Smart Appliances, Smart Street Lighting
and Smart Roads is growing by 20% p.a. and will total 46 TWh by the year 2025, according to a new report from IEA-4E.
 Home Automation and
Smart Appliances make up 93% of this total.

However, the report notes that the selection of appropriate, low-energy communication technology options (see figure above) would reduce the network standby energy consumption of IoT devices. 

A report from the Consumer Technology Association estimates that home automation could save from 1%-5% percent of total residential primary energy consumption in the USA, depending upon how the market develops and how users choose to control their automated household devices and equipment. 

Specifically looking at connected thermostats, HVAC zoning control, window covering control, occupancy-based lighting control and circuit-level control, the report notes that these technologies can also improve demand response capabilities.

GfK’s measure of how people are digitally connecting with each other shows a 200% leap in growth globally between 2010 and 2016.  In China, consumers are four times more connected now than they were in 2010, while North American consumers are the most connected.

The index measures the following 11 device types: smartphone, tablet, mobile PC, desktop PC, wearables, smart TV, set-top box, games console, e-reader, connected cars and smart homes. 


There is no formal membership of the CDA and we welcome all government and industry participants in the CDA.

Support the CDA Voluntary Principles for Energy Efficient Connected Devices 
The CDA is seeking public support for our voluntary guidelines designed to encourage greater energy efficiency in the development of policies and connected products.

Jointly developed by industry and government representatives, the CDA Principles have two focuses: 
  • The CDA Voluntary Design Principles provide guidance on the key features of energy efficient connected devices, networks and communications protocols - for use by designers, manufacturers and protocols authors
  • The CDA Policy Principles encourage a common global framework for the development of government policies and related measures - for use by policy makers
Submit publications for the Centre of Excellence
The Centre of Excellence provides a one-stop-shop for information on energy efficiency in networked devices and their networks.  If you already have relevant materials that might inform the debate on policies in this field, follow the link below to view the guidelines and submit papers.
