Chair’s Statement

Once again Energy has dominated headlines during 2022 for all the wrong reasons! Few parts of the globe have escaped without experiencing escalating costs and concerns about security of supply.

The hardships this has caused has only reinforced the need to accelerate our transition to a more sustainable, affordable global energy system, where energy efficiency and demand flexibility plays a central role. As noted by our previous Chair in last year’s Annual Report: “energy efficiency is the component that makes the transition to clean energy sufficiently robust, affordable and timely.”

But words are not enough and so it is particularly pleasing to see evidence that 4E activities really do help governments to implement policies that make a difference on the ground.

Through this research and collaboration, our Members have become ever more ambitious in 2022, developing innovative policy approaches that are driving technological advances. Importantly, 4E provides a mechanism for sharing these innovations amongst Members and to other economies in all regions.

The sharing of information and expertise has always been at the core of 4E’s work, whether this is between governments or by engaging with industry and other stakeholders. This has been challenging during the Covid pandemic, but through the increasing use of webinars and other on-line platforms, we have reached out to more people than in previous years.

In 2022, exceptional collaborative efforts by 4E’s EDNA, EMSA, PECTA and SSL Annexes have created a range of practical, topical, and valuable policy advice and leading edge research that is freely available and disseminated worldwide.

In November 2022, at our first face-to-face meeting for three years, 4E began the process of deciding on our major activities during our next five-year term starting in 2024. The world looks very different to how it did at the start of this term, and there is no shortage of valuable opportunities for 4E to consider. However, our limited resources demand that we focus on areas where the collaboration between Member governments can make most impact.

What is certain is that our immense body of work over previous years, combined with the expertise and engagement of our Members, gives us a unique platform for launching the next phase.

Policy Packages for Energy Efficiency

Policy Packages for
Energy Efficiency

To support stronger action on efficiency the IEA has designed a policy toolkit for governments, launched at the IEA’s 7th Annual Global Conference on Energy Efficiency in June 2022. The toolkit provides a practical approach to accelerate action on energy efficiency by guiding governments in the design of effective policy measures, the support of policy decisions and the delivery of policy actions.

The Role played by 4E

Not since the founding of the IEA in 1974 has the need for a coordinated effort on energy efficiency to reduce wasteful and inefficient use of energy been so great. No other energy resource can compare with energy efficiency as a solution to the energy affordability, security of supply and climate change crises. This is why the IEA calls energy efficiency the “first fuel” of all energy transitions.

IEA Energy Efficiency 2022

4E aims to promote energy efficiency as the key to ensuring safe, reliable, affordable and sustainable energy systems.

Annexes

Annexes provide a mechanism for collaborative research amongst 4E Members on key technologies or topics.

The 4E structure is shown below, and this highlights the four existing Annexes:

Reports on all currently operating Annexes are included later in this report.

There are about 300 million electric motors operating in the world today and only about 20% equipped with a variable speed drive that makes them more efficient. By adding these drives to the rest of these motors worldwide, we could save 10% of the electricity in the world, we’re talking about a really huge number just to drive that efficiency.

4E Projects

4E projects are developed and funded by the Executive Committee to support policies for energy efficient end-use equipment. These research activities cover a wide range of technologies and cross-cutting issues and benefit from the collective insights provided by all 4E Members.

The achievements in 2022 of the most prominent 4E projects are illustrated below.

Product Energy Efficiency Trends (PEET)

The PEET project assists 4E Members to compare the performance of major products across economies and regions by examining the scope and stringency of regulatory policies within these economies.

PEET provides a mechanism for policy makers and regulators to understand the differences in scope, test methods and stringency of national regulations and helps to bring them into closer alignment.

4E Members met in 2022 for five workshops to discuss the following important topics of significant relevance to several countries:
  • Regulatory proposals for televisions, computer monitors and digital signage displays in Australia and New Zealand (15 June, online)
  • Embedded motors (7 September, online)
  • Testing luminance in electronic displays (5 October, online)
  • Heat pumps for hydronic heating applications (14 November, Utrecht)
  • Demand flexibility in appliances and equipment (16 November, Utrecht)
In addition, we launched a new ‘web crawler’ project in 2022 that will collect energy performance and price information for refrigerator/freezers, televisions, room air-conditions, and washing machines. Data will be collected in four separate ‘crawls’ between mid-2022 to the end of 2023.

Figure 1: Illustration of influence of luminance and screen area on power consumption in TVs

Grey plane = best fit of power against luminance and screen area
Blue plane = best fit relationship between screen size and power

Through PEET, Australia is able to engage directly with policy makers in other countries and gain valuable insights into alternative policy approaches. Being able to discuss topics in depth with peers in other governments, share information and our experiences not only helps Australia to develop more effective policy solutions, but also encourages greater international harmonisation and allows others to benefit from Australia’s knowledge and experience.

Load Based Testing for Variable Speed 
Air Conditioners and Heat Pumps

Responding to the need to develop practical load-based testing regimes for air conditioners and heat pumps, this 4E project commenced in late 2020 and concludes with a series of round-robin tests in laboratories selected by 4E Members.

Having published new test guidance suited to variable capacity units at the end of 2021, the round robin of two ducted and two non-ducted units began in 2022 with tests conducted in the US.

The units are currently being tested in Denmark, Korea and Australia, with the results to be analysed in 2023.

Evaluation Guide for EES&L Programmes

This Guidebook is intended to promote impact evaluations of equipment energy efficiency standards and labelling (EES&L) programmes in a consistent and transparent manner.

While not being prescriptive, it explains the key methods that are proven to deliver robust and credible evaluations within a simple guide. Since previous 4E projects have found that it is sometimes difficult to understand the assumptions used in the presentation of programme outcomes, the guide also covers the reporting of results.

Since evaluations are often undertaken by an independent third party, the guide is designed to provide a clear scope of work or request for proposals (RFP), however, it may also be used to plan in-house evaluations of EES&L programmes.

While we know that energy efficiency programmes are highly cost-effective and have multiple benefits, we all need to continually demonstrate the scale of these achievements. By publishing this practical Guidebook we hope to encourage EES&L programmes to conduct more thorough and transparent examinations of their results. In this way, we can extend the evidence base and gain further support to be ever more ambitious.

Regulating Energy Using Systems

Extending product policies to cover relevant energy-using systems has the potential to reduce annual global energy consumption by 9% (17,000 PJ, 4,780 TWh). This is larger than the total annual use of electricity in the United States in 2021. It is also more than three times the electricity savings generated by the nine most successful national standards and labelling programmes for individual products1.

This is why 4E has been working on practicalities of extending product regulations to energy-using systems.

Figure 2: Estimates of energy savings if product policies were extended to cover energy-using systems

In 2022, 4E published ‘Progressing Energy Efficiency Policies for Systems’, a summary of the work undertaken by 4E over the previous four years. This includes estimates of savings potential, options for overcoming some of the hurdles to regulation and the identification of system types that are most suitable for the next generation of energy efficiency regulation.

This work is ongoing and 4E welcomes interaction with others interested in investigating this topic more widely.

4E’s research published in 2022 shows that the potential energy savings from regulating energy-using systems could dwarf the already considerable savings made by regulating products. However, we have also studied the considerable legal, administrative, and technical barriers in depth, so we are aware of the difficulties ahead. However, the scale of potential savings together with 4E’s mission to consider topics that are not being addressed by other international collaborations justifies 4E’s investment of time and effort in finding solutions.

IEA Publications

4E works closely with the IEA and provides expert input to many reports, including combining on joint publications and events. This gives high level visibility to much of 4E’s research work.

4E makes a significant contribution to the appliance & equipment sections of the IEA’s annual flagship publications on energy efficiency and on digitalisation.

Further examples of collaborative work with the IEA and other TCPS are shown later in this report.

Every year the 4E TCP delivers important developments in the understanding of how to improve end-use energy efficiency and provides meaningful contributions to IEA work and several of its major publications. For example, the IEA’s flagship publication, Energy Efficiency 2022, cited 4E’s analysis of the energy consumption by systems and drew on other valuable 4E work. The value of our collaboration with 4E is particularly evident the field of Digitalisation, where the work of 4E continues to provide insights into the role this can play in encouraging energy systems to use energy more efficiently.

Regulating Energy Using Systems

Extending product policies to cover relevant energy-using systems has the potential to reduce annual global energy consumption by 9% (17,000 PJ, 4,780 TWh). This is larger than the total annual use of electricity in the United States in 2021. It is also more than three times the electricity savings generated by the nine most successful national standards and labelling programmes for individual products1.

This is why 4E has been working on practicalities of extending product regulations to energy-using systems.

Figure 2: Estimates of energy savings if product policies were extended to cover energy-using systems

In 2022, 4E published ‘Progressing Energy Efficiency Policies for Systems’, a summary of the work undertaken by 4E over the previous four years. This includes estimates of savings potential, options for overcoming some of the hurdles to regulation and the identification of system types that are most suitable for the next generation of energy efficiency regulation.

This work is ongoing and 4E welcomes interaction with others interested in investigating this topic more widely.

4E’s research published in 2022 shows that the potential energy savings from regulating energy-using systems could dwarf the already considerable savings made by regulating products. However, we have also studied the considerable legal, administrative, and technical barriers in depth, so we are aware of the difficulties ahead. However, the scale of potential savings together with 4E’s mission to consider topics that are not being addressed by other international collaborations justifies 4E’s investment of time and effort in finding solutions.

Co-ordination with IEA and other organisations

Co-ordination with IEA and other organisations

As one of 38 Technology Collaboration Programmes established under the framework of the International Energy Agency (IEA), 4E has a particularly close relationship with the IEA Secretariat.

Some examples of collaborative activities in 2022 include:

  • 4E made a significant contribution to the IEA flagship publication ‘Energy Efficiency 2022’
  • 4E EDNA and the IEA’s 3DEN Initiative held webinars on:
    • ‘Interoperability of household appliances and equipment’, November 2022
    • ‘Blockchain applications: an energy perspective’, April 2022
  • The 4E Electric Motor Systems Annex participated in the expert panel on ‘Super-Efficient Appliances Pave the Way to Net-Zero’, which took place in the framework of the 7th Annual Global Conference on Energy Efficiency, June 2022 in Sønderborg, Denmark
  • The IEA’s Energy Efficiency Division provides a report to each meeting of the 4E Executive Committee and participates in discussions at these meetings

4E also regularly liaises with other Technology Collaboration Programmes

4E and Industry

4E has extensive contact with a variety of industry organisations and companies. We run regular workshops to gain industry input to 4E’s work. These tend to focus on private sector companies related to our workstreams, such as suppliers of motor systems, solid state lighting, power electronics, ICT equipment and air conditioning.

Although some of the face-to-face interactions have been curtailed as a result of Covid, 4E has increased the number of Webinars that it runs during 2022, usually in collaboration with the IEA, and these continue to attract many hundreds of industry participants spanning a variety of technology and policy topics.

Depending on the topic, we may also seek industry comments on our published materials or conduct formal consultation processes. 4E Members also participate in many formal standardisation processes, contributing to the results of work undertaken by 4E, which has often been commissioned specially to inform standards development.

Doubling the rate of global energy intensity improvement from the 2% per year achieved from 2010 to 2020 to just over 4% from 2020-30 is necessary to put the world on a pathway consistent with the Net Zero Scenario. Doing so will require enhanced action on a wide spectrum of energy efficiency and demand-side measures covering technical efficiency, behaviour change and electrification, as well as material efficiency, digitalisation and fuel switching in industry.

Annex Achievements in 2022

Governments should embed connectivity and smart functionality requirements as part of minimum energy performance standards for high-consuming devices, such as air conditioners, heating systems, heat pumps, water boilers and electric vehicle charging, and include these requirements in energy efficiency standards for buildings. This would also unlock opportunities for private charging infrastructure to provide grid services and act as a responsive distributed energy resource. The adoption of future-ready devices and systems can also be supported by providing incentives to consumers in the form of rewards.

Major Achievements During 2022

The EMSA project ‘Round Robin for Converter Losses’ was concluded in 2022. This international testing campaign was implemented in co-operation with the IEC and independent testing laboratories between 2017 and 2022. It is the first independent publicly available study to systematically analyse the electric losses and efficiency of converters. The modifications included in the Round Robin Uniform Testing Protocol were incorporated in the second revision of IEC 61800-9-2. The Round Robin showed that almost all converters on the market easily reach the most efficient (IE2) class. These outcomes underline the importance of EMSA’s independent, evidence-based voice in international standardisation.

The joint working group JAG 22, that was established as a result of EMSA’s initiative, has begun to integrate relevant materials from IEC electric motor and converter standards into an ISO fan standard. As a result, it will be possible to make more precise calculations for each operating condition as deemed necessary for each type of application.

A small-scale Round Robin for air compressors has been launched which aims to develop and trial a guide to the air compressor energy efficiency measurement method. Eventually the results will be used to modify the ISO test standard.

EMSA published the report ‘Classification of digitalisation technologies for electric motor driven systems’. The report is a stepping stone for further work analysing possibilities for increased energy efficiency through the digitalisation of motor systems.

Some of the key digital technologies assessed in the report that enable energy efficiency in motor driven systems during the use phase are shown below.

VIEW REPORT

EMSA has worked on improving the user support of the Motor Systems Tool by establishing an expert pool to address questions from users. The tool was also extended with loss models from the ANSI/AMCA Standard 207-17. All these efforts contribute to making the tool even more suitable for uptake into national policies; for example, New Zealand is currently running a pilot using the Motor Systems Tool for selected industrial sites.

Solid State Lighting technology can cut lighting electricity consumption in half or more. Now in our 13th year, the SSL Annex continues to focus on four critical areas of work:
  • SSL product quality and performance;
  • SSL testing, metrics and standards;
  • Health, productivity and environmental impacts; and
  • Smart lighting, digitalisation and connectivity.
All these activities are policy-driven with a focus on how to best implement policy and standards. This work complements academic research, international standardisation and R&D conducted by industry.
For an individual government, few have the resources to replicate these tasks, or facilitate the information exchange and knowledge transfer that occurs within the SSL Annex. The body of work is carried out primarily through members’ in-kind contributions, with part of the work contracted to experts when necessary.
The SSL Annex provides information and analysis that is highly relevant for current regulatory processes in several countries, as well as for international standardisation work in which several Member governments are engaged.
Testing continues to be a key focus area. The SSL Annex completed the world’s largest interlaboratory comparison for goniophotometers, holding two public webinars in January 2022. The work to compare nucleus labs for a new interlaboratory comparison of methods to test light modulation has now begun.
The performance of SSL products remains important, and the Annex’s quality and performance recommendations were published in early Q2 2022.

VIEW REPORT

The EDNA Annex is focussed on the energy aspects of smart devices and associated networks. There is significant potential for internet-connected equipment to save energy, by way of remote controllability, cloud control and smart algorithms. Controllability also allows connected devices to be operated so that they become useful for the electricity grid. For example, at times of high power demand, certain devices can be de-prioritised, and at times of high power generation (e.g. during sunny weather) devices can be turned on to ‘soak up’ excess solar energy. This ‘demand flexibility’ is increasingly important as renewable energy sources play a larger role in the power grid. EDNA research on this topic led to several publications in 2022, along with a report dealing with the energy that connected devices use to stay connected to the internet.

Alongside these topics, EDNA has commenced a workstream on data centres. Data centres are an integral part of the smart device ecosystem, and consume considerable amounts of energy. In 2022 EDNA produced a report on energy efficiency metrics for data centres, and has several more studies in the pipeline, all aimed at policy makers who wish to influence the energy consumption of data centres.

EDNA is uniquely positioned to affect change in these areas, as its members are government policy makers who are committed to collaborating in order to share knowledge and reduce costs. EDNA also works closely with other organisations such as the IEA, the Connected Devices Alliance, the Users TCP and the newly-formed Energy Efficiency Hub. With these partners EDNA has undertaken collaborations and held joint public webinars in order to disseminate our work.

In the field of demand flexibility, EDNA published 2 reports. The first deals with the ‘application layer’ protocols that devices use to communicate, in particular when communicating with the power grid in order to provide demand flexibility. Standardising these protocols is essential to ensure that devices are ready to provide grid services in future. The second report dealt with a related topic – interoperability. Interoperability is the ability for devices not only to communicate with the grid, but with each other, which is vital if the energy saving and demand flexibility opportunities offered by smart devices are to be capitalised on. Following publication of the report, EDNA hosted a webinar with the IEA on this topic.

DOWNLOAD POLICY BRIEF

The Power Electronic Conversion Technology Annex (PECTA) focuses on investigating the efficiency potential of new semiconductor technologies in power electronic applications, particularly in the area of wide bandgap (WBG) semiconductors such as silicon-carbide (SiC) and gallium nitride (GaN).

These WBG semiconductors are expected to have better material characteristics compared to traditional silicon-based components and could lead to energy savings in a wide range of power electronics applications.

Through research, PECTA aims to identify the energy efficiency savings outlook from the adoption of WBG components in different applications, and to develop a roadmap for their market adoption in relevant fields. PECTA also conducts a life cycle assessment (LCA) of WBG devices to evaluate their energy consumption during the manufacturing process.

By bringing together academia, industry, and policymakers, PECTA creates a platform for knowledge sharing and collaboration to explore the potential energy efficiency improvements from adopting WBG materials in market-ready products. The unique approach of PECTA creates new insights and perspectives, not only for the scientific community, but also for stakeholders in different fields from component design to system manufacturing.

PECTA is unique in its approach of bringing together academia, industry, and policymakers to explore the potential of WBG semiconductors in power electronics applications. The industry advisory group within PECTA ensures that the research is relevant to industry needs and the development of new technologies. In addition, PECTA collaborates with other organisations such as the European Centre for Power Electronics (ECPE) to create a broader knowledge-sharing network.

The focus on energy efficiency and environmental impacts sets PECTA apart from other initiatives in the power electronics field, and its research contributes to the global effort to reduce greenhouse gas emissions. PECTA’s work is also complementary to the work of other organisations focused on power electronics, such as the International Electrotechnical Commission (IEC), which develops standards for power electronics components and systems. By working together with other stakeholders, Annexes or technology programmes, PECTA contributes to the development and adoption of more energy-efficient technologies and promotes sustainable practices in the power electronics industry.

Annex Achievements in 2022

Governments should embed connectivity and smart functionality requirements as part of minimum energy performance standards for high-consuming devices, such as air conditioners, heating systems, heat pumps, water boilers and electric vehicle charging, and include these requirements in energy efficiency standards for buildings. This would also unlock opportunities for private charging infrastructure to provide grid services and act as a responsive distributed energy resource. The adoption of future-ready devices and systems can also be supported by providing incentives to consumers in the form of rewards.

Major Achievements During 2022

The EMSA project ‘Round Robin for Converter Losses’ was concluded in 2022. This international testing campaign was implemented in co-operation with the IEC and independent testing laboratories between 2017 and 2022. It is the first independent publicly available study to systematically analyse the electric losses and efficiency of converters. The modifications included in the Round Robin Uniform Testing Protocol were incorporated in the second revision of IEC 61800-9-2. The Round Robin showed that almost all converters on the market easily reach the most efficient (IE2) class. These outcomes underline the importance of EMSA’s independent, evidence-based voice in international standardisation.

Figure 3: IE-index for 3-phase Basic Drive Modules over nominal output current at (90:100) duty point. Dotted line is the threshold between IE2 (below the line) and IE1 (above the line). Orange crosses: without filter, blue crosses: with filter.

The joint working group JAG 22, that was established as a result of EMSA’s initiative, has begun to integrate relevant materials from IEC electric motor and converter standards into an ISO fan standard. As a result, it will be possible to make more precise calculations for each operating condition as deemed necessary for each type of application.

A small-scale Round Robin for air compressors has been launched which aims to develop and trial a guide to the air compressor energy efficiency measurement method. Eventually the results will be used to modify the ISO test standard.

EMSA published the report ‘Classification of digitalisation technologies for electric motor driven systems’. The report is a stepping stone for further work analysing possibilities for increased energy efficiency through the digitalisation of motor systems.

Some of the key digital technologies assessed in the report that enable energy efficiency in motor driven systems during the use phase are shown below.

VIEW REPORT

EMSA has worked on improving the user support of the Motor Systems Tool by establishing an expert pool to address questions from users. The tool was also extended with loss models from the ANSI/AMCA Standard 207-17. All these efforts contribute to making the tool even more suitable for uptake into national policies; for example, New Zealand is currently running a pilot using the Motor Systems Tool for selected industrial sites.

Solid State Lighting technology can cut lighting electricity consumption in half or more. Now in our 13th year, the SSL Annex continues to focus on four critical areas of work:
  • SSL product quality and performance;
  • SSL testing, metrics and standards;
  • Health, productivity and environmental impacts; and
  • Smart lighting, digitalisation and connectivity.
All these activities are policy-driven with a focus on how to best implement policy and standards. This work complements academic research, international standardisation and R&D conducted by industry.
For an individual government, few have the resources to replicate these tasks, or facilitate the information exchange and knowledge transfer that occurs within the SSL Annex. The body of work is carried out primarily through members’ in-kind contributions, with part of the work contracted to experts when necessary.
The SSL Annex provides information and analysis that is highly relevant for current regulatory processes in several countries, as well as for international standardisation work in which several Member governments are engaged.
Testing continues to be a key focus area. The SSL Annex completed the world’s largest interlaboratory comparison for goniophotometers, holding two public webinars in January 2022. The work to compare nucleus labs for a new interlaboratory comparison of methods to test light modulation has now begun.
The performance of SSL products remains important, and the Annex’s quality and performance recommendations were published in early Q2 2022.

VIEW REPORT

The EDNA Annex is focussed on the energy aspects of smart devices and associated networks. There is significant potential for internet-connected equipment to save energy, by way of remote controllability, cloud control and smart algorithms. Controllability also allows connected devices to be operated so that they become useful for the electricity grid. For example, at times of high power demand, certain devices can be de-prioritised, and at times of high power generation (e.g. during sunny weather) devices can be turned on to ‘soak up’ excess solar energy. This ‘demand flexibility’ is increasingly important as renewable energy sources play a larger role in the power grid. EDNA research on this topic led to several publications in 2022, along with a report dealing with the energy that connected devices use to stay connected to the internet.

Alongside these topics, EDNA has commenced a workstream on data centres. Data centres are an integral part of the smart device ecosystem, and consume considerable amounts of energy. In 2022 EDNA produced a report on energy efficiency metrics for data centres, and has several more studies in the pipeline, all aimed at policy makers who wish to influence the energy consumption of data centres.

EDNA is uniquely positioned to affect change in these areas, as its members are government policy makers who are committed to collaborating in order to share knowledge and reduce costs. EDNA also works closely with other organisations such as the IEA, the Connected Devices Alliance, the Users TCP and the newly-formed Energy Efficiency Hub. With these partners EDNA has undertaken collaborations and held joint public webinars in order to disseminate our work.

In the field of demand flexibility, EDNA published 2 reports. The first deals with the ‘application layer’ protocols that devices use to communicate, in particular when communicating with the power grid in order to provide demand flexibility. Standardising these protocols is essential to ensure that devices are ready to provide grid services in future. The second report dealt with a related topic – interoperability. Interoperability is the ability for devices not only to communicate with the grid, but with each other, which is vital if the energy saving and demand flexibility opportunities offered by smart devices are to be capitalised on. Following publication of the report, EDNA hosted a webinar with the IEA on this topic.

DOWNLOAD POLICY BRIEF

The Power Electronic Conversion Technology Annex (PECTA) focuses on investigating the efficiency potential of new semiconductor technologies in power electronic applications, particularly in the area of wide bandgap (WBG) semiconductors such as silicon-carbide (SiC) and gallium nitride (GaN).

These WBG semiconductors are expected to have better material characteristics compared to traditional silicon-based components and could lead to energy savings in a wide range of power electronics applications.

Through research, PECTA aims to identify the energy efficiency savings outlook from the adoption of WBG components in different applications, and to develop a roadmap for their market adoption in relevant fields. PECTA also conducts a life cycle assessment (LCA) of WBG devices to evaluate their energy consumption during the manufacturing process.

By bringing together academia, industry, and policymakers, PECTA creates a platform for knowledge sharing and collaboration to explore the potential energy efficiency improvements from adopting WBG materials in market-ready products. The unique approach of PECTA creates new insights and perspectives, not only for the scientific community, but also for stakeholders in different fields from component design to system manufacturing.

PECTA is unique in its approach of bringing together academia, industry, and policymakers to explore the potential of WBG semiconductors in power electronics applications. The industry advisory group within PECTA ensures that the research is relevant to industry needs and the development of new technologies. In addition, PECTA collaborates with other organisations such as the European Centre for Power Electronics (ECPE) to create a broader knowledge-sharing network.

The focus on energy efficiency and environmental impacts sets PECTA apart from other initiatives in the power electronics field, and its research contributes to the global effort to reduce greenhouse gas emissions. PECTA’s work is also complementary to the work of other organisations focused on power electronics, such as the International Electrotechnical Commission (IEC), which develops standards for power electronics components and systems. By working together with other stakeholders, Annexes or technology programmes, PECTA contributes to the development and adoption of more energy-efficient technologies and promotes sustainable practices in the power electronics industry.

4E Group Finances

4E Group Finances

In 2022, the total cost of 4E activities is estimated to be approximately €1.9 million.

4E activities are made possible through the contributions of member countries: taking the form of annual fees and substantial in-kind work by national experts. In 2022, the annual fees of the 15 Members funded 45% of the total expenditure.

The large majority of funding is directed towards our research activities. Approximately 15% of funds were used for communication, while only 7% were spent on administration and financial management, the same as in the previous year.

Around 10.9 million people were employed in energy efficiency in buildings and industry in 2019, with one-third of these jobs located in China, followed by around 2 million in North America.
