China is the world’s most populous country currently and fourth-largest in area. To reconcile energy and development goals, it is developing clean energy and has vigorously pursued energy efficiency policies for several decades.
China aims to transition its economy to a less carbon- and energy-intensive model. While coal and oil dominate energy supply, policies emphasise renewable and nuclear electricity and cleaner, efficient technologies.
The country has many energy efficiency programmes, including building, equipment and appliance energy performance standards and labels, and the Top 10,000 scheme requiring industrial firms to set targets for and invest in energy efficiency.
China is represented on the Hub’s Steering Committee by the National Development & Reform Commission, leads the TOP TENs Task Group, participates in several Task Groups, and contributes to the Hub’s Policy Exchange Workshops.
Brazil is the fifth-largest country in the world by area and the largest energy consumer in South America. It has long-standing national energy efficiency policies, including utility-funded programmes for consumers and appliance energy standards and labels.
Renewables meet 45% of Brazil’s primary energy demand, making the energy sector one of the least carbon-intensive in the world. Hydropower accounts for around 80% of electricity generation.
Key policy mechanisms include building codes, standards for space cooling equipment and measures promoting energy management systems.
Brazil is represented on the Hub’s Steering Committee by the Ministério de Minas e Energia, participates in all Task Groups, and contributes to the Hub’s Policy Exchange Workshops.
Japan is an island country with the third-largest economy in the world. It relies heavily on imports of fossil fuels, has a high share of nuclear power in its electricity mix, and has been a global leader in energy efficiency for decades.
In recent years, Japan has become increasingly reliant on imports of oil, coal, and natural gas, which together account for 88% of Japan’s energy consumption.
The country has long-standing national policies and measures to foster energy efficiency. These include voluntary actions for industry (like the Top Runner Programme), vehicles and appliances. Standards are in place for products, vehicles, and industrial sectors.
Japan is represented on the Hub’s Steering Committee by the Ministry of Economy, Trade and Industry, leads the EMAK Task Group, participates in all Task Groups, and contributes to the Hub’s Policy Exchange Workshops.
Korea is one of the most economically developed nations in East Asia. The government has announced policies that would significantly accelerate energy efficiency improvements.
Korea depends on fossil fuel imports, which account for 85% of the country’s total energy supply. Policies aim to significantly improve energy efficiency and the share of renewable electricity, while gradually phasing out coal and nuclear power.
The Green New Deal and Energy Master Plan are key legislations aimed at supporting the energy transition. The Energy Efficiency Innovation Strategy supports deployment of information and communication technologies, energy management systems, intelligent transport systems and virtual power plants.
Korea is represented on the Hub’s Steering Committee by the Korean Energy Agency, participates in several Task Groups, and contributes to the Hub’s Policy Exchange Workshops.
Russia, stretching across Europe and Asia, is the world’s largest country by size and a leading global exporter of energy. The country’s Energy Agency is responsible for the country’s energy efficiency policy measures.
Russia is the world’s second-largest producer of natural gas and its largest exporter, and a leading oil exporter.
The country has created a legal and institutional framework to enhance efficient energy use. The Energy Strategy of Russia, adopted in 2009 includes a number of regional energy efficiency measures.
Russia participates in Task Groups and in the Hub’s Policy Exchange Workshops.
The Top Ten Energy Efficiency Best Available Technologies and Best Practices Task Group aims to stimulate uptake of energy efficiency in key energy consuming sectors by:
TOP TENs was jointly established by Australia and China in 2013. Since then, the Task Group has published several lists of best available technologies and best practices featuring cutting-edge approaches and case studies.
Best practices cover all sectors apart from agriculture, and include case studies like university-wide efforts to build a smart campus, the application of passive house technology, energy management award programmes, and more.
Best available technologies refer to specific technologies like dimming, co-generation, heat pumps, and industrial waste heat recovery. The lists do not include specific brands.
Technical experts from Member countries nominate the initial list of best technologies and best practices. Then, the Task Group begins the evaluation process, which involves scoring based on a 100-point evaluation system. Some of the key evaluation criteria include energy savings potential, level of innovation, efficiency, economic and social benefits, environment, health, and safety. As a result, the Task Group produces national and international lists of top technologies and practices to save energy.
The work of TOP TENs is relevant to policy makers and stakeholders in industry, buildings, and transportation.
Since the launch of TOP TENs, the Task Group members have played active roles in developing and promoting the Task Group.
The group produced two international TOP TENs lists of the most energy-efficient technologies and practices to reduce energy demand and emissions.
The work of TOP TENs was presented at the G20 Global Summit on Financing Energy Efficiency, Innovation and Clean Technology in 2019, China Energy Conservation Week in 2019, 2020, 2021, and 2022, and Japan ENEX (Energy and Environment Exhibition) in 2020.
