Joint workshop
International Energy Agency (IEA) Energy Efficiency Unit
IEA Implementing Agreement for Efficient Electrical End-use Equipment (4E) Standby Power Annex
Super Efficient Appliance Deployment (SEAD) Initiative working group on network standby
Common objectives:
Tracking emerging issues and monitoring trends & providing recommendations on how to develop and implement effective energy efficiency policies
Creating opportunities for sharing policy experiences
Creating fora for discussion
© OECD/IEA 2010
Key messages Network connectivity is a good thing – opportunity for
new functions, services including energy saving
But if left un-managed – energy efficiency opportunities will be missed
Network standby is a topic of growing importance
There is an urgent need for a policy response
There are technical and policy solutions
No need to start from scratch – but instead opportunity to build on existing initiatives
Network standby is one issue – more work is needed on promoting energy efficiency in networked systems and environments
Opportunities to utilise energy saving opportunities that networks can unlock should be identified and pursued
© OECD/IEA 2010
Trends standby energy use is increasing
uptake of electronics is increasing
energy demand of electronics is increasing
products are increasingly networked
product development is increasingly at a rapid rate
ICT energy consumption is projected to grow at a rapid rate

But standby energy consumption is increasing – in some countries up from 10% of total residential demand to 16%

Recommendations Develop and implement policies (building on existing
initiatives/approaches or aligning where possible)
o Utilise and scale up existing fora for knowledge exchange
Ensure a robust technical foundation
o Data collection strategy
o Support greening communication protocols
o Support development of international test procedures
Work towards promoting energy efficiency throughout network connected systems
Through vigilance and concerted positions – be in a position to utilise energy efficiency opportunities
