The Top Ten lists have been developed to highlight energy savings technologies and practices for Australian industry that represent good value for money, are innovative, reliable and widely available.

The lists are divided into Top Ten Technologies and Top Ten Practices and are collated from 2011−12 Energy Efficiency Opportunity (EEO) reports from high energy-using companies.

Each technology and practice has been weighted using an internationally agreed methodology to determine its energy saving potential, technical, social and financial characteristics.

How to use the lists

Energy and sustainability managers and engineers responsible for identifying and implementing energy efficiency opportunities can use the lists to consider the benefits of processes and practices relevant to their work.

Top Tens Task Group

The Top Tens Task Group is managed through the International Partnership for Energy Efficiency Cooperation (IPEEC). The group was established in 2013 and is led by Australia and China. Other members include Japan, the US, South Korea, Canada and France.

The objective of the task group is to improve energy efficiency globally through better exchange of information about technologies and practices. Members of the task group are developing domestic and international Top Ten lists, with related case studies, to provide practical information for industrial energy users. These will have broad international relevance and provide a range of comparative case studies in different national contexts.

These lists will then be promoted to energy users and energy policymakers internationally through a range of different channels.

China and Japan have also completed Top Ten lists which will be available in early 2016 on the IPEEC website. Future developments and updates from the task group will also be included there.

Australian companies can review Australia’s Top Tens to identify initiatives which will provide the best energy and cost savings for their organisation. The Australian Top Tens lists provide information on the technologies and practices identified as the best available, including supporting data, examples and resources to demonstrate how the technologies and practices can be applied in different settings.
