Networked Devices Task Group (NDTG)

It is predicted that in future almost all electrical devices will be connected to the internet. However each connected device needs an “internet protocol address”. In 1980 the number of available internet protocol addresses was 4.3 billion, which was envisaged to be sufficient to cater for all devices that might ever be connected. In recent years it was realized that this would not be enough, and the number of available addresses was increased to more than 3×1038. In other words a 3 followed by 38 zeros - 300 billion billion billion billion.

With device connectivity comes significant opportunities for societal improvement, including energy savings from what is called “intelligent efficiency” - the ability to operate systems of connected devices efficiently.

However, there is also an energy cost associated with connectivity - it requires a small amount of energy - around the clock - to maintain a network connection for each of the many billions of devices predicted to be connected to the internet.

In order to address this challenge, as well as to ensure that the energy saving opportunities are maximized, the Networked Devices Task Group (NDTG) was established in 2015, following the 2014 G20 summit. To widen the reach to industry, this group then conceived the Connected Device Alliance (CDA) which consists of more than 350 government and industry participants that have come together to work on the energy efficiency opportunities provided by connected devices.

During 2015 the NDTG/CDA developed an over-arching vision and proposed a number of key initiatives, including:

Why do appliances and equipment matter for energy efficiency?
 

Recent developments

Throughout 2017, the CDA encouraged globally coordinated action on connected devices through:

  • Promotion of the CDA Voluntary Principles for Energy Efficient Connected Devices, which have been officially supported by a number of industry groups and governments.
  • Expansion of the CDA Centre of Excellence, an online publications library that provides free and in-depth papers by experts on ways to encourage energy efficient smart devices.
  • Organisation of a G20 Networked Devices Workshop in March in Berlin, Germany. The event brought together representatives from government, industry and academia to shape recommendations to G20 members on connected devices.
  • Development of the Connected Efciency Award in cooperation with SEAD and IEA 4E’s EDNA annex.
  • Facilitation of a CEM Roundtable on the “Digitalisation of the Energy Sector to Enhance Energy Productivity and Renewables Integration” in June in Beijing, China.
  • Substantial contributions to the IEA report Digitalisation and Energy published in November.
