Energy Efficiency in China’s Buildings Sector
…progress in achieving them. Regulation for new buildings in China, such as building codes, is relatively strong. However, as the rate of construction is slowing, policy priorities are shifting towards retrofitting existing buildings. Here, the IEA estimates that through strong policy action and best-in-class technology, China could reduce energy consumption by up to 65% in buildings constructed between 1995 and 2010, representing energy savings of over 8 000 Petajoules.The report includes examples from across China and the world on leading regulatory instruments, financial incentives, and information-based tools that can drive energy efficiency in the buildings sector.

Evolving Energy Service Companies in China
Evolving Energy Service Companies in China Energy service companies (ESCOs) deliver energy efficiency projects that are financed through the resulting energy cost savings. ESCOs can thus unlock energy efficiency action by addressing barriers related to funding and technical expertise. Despite their potential, many governments still struggle to stimulate development of a market for ESCOs. Evolving Energy Service Companies in People’s Republic of China, (“China” hereafter) provides an overview of how China has built the world’s largest and fastest growing ESCO market over the past decades. This report highlights how the government’s strategic measures to set up key…

E4 Country Profile: Energy Efficiency in China
…crucial to limiting the increase in energy use resulting from high rates of construction and higher rates of appliance ownership. Energy efficiency opportunities China has enormous energy efficiency improvement potential according to the IEA’s Efficient World Scenario (EWS). Ensuring that China seizes all efficiency opportunities in a cost-effective manner will be crucial for both China and the world’s transition to low-carbon energy.Energy consumption could reach a peak by 2030 and save 16 EJ - the equivalent of France and Germany’s energy use - by 2040 compared to current trends. These savings would come from the industrial…

…low levels of policy coverage. Energy efficiency opportunities By 2040, under the NPS, the country would see a 75% increase in energy demand compared to today. The Efficient World Scenario could limit this growth to just 50% reducing energy consumption by 2 EJ with savings mainly coming from the buildings (38%) and industrial (35%) sectors, followed by the transport sector. The cost effective measures incorporated in the EWS would also reduce CO2 emissions by 120 Mt CO2-eq by 2040 compared to expected trends and save households USD 7 billion due to reduced energy bills, as well as provide 26…

The Role of Gas in Today's Energy Transitions
…In this analysis, we explore how widespread and durable this role might be in some of today's key energy markets. The Role of Gas in Today's Energy Transitions examines the role of fuel switching, primarily from coal to natural gas, to reduce CO2 emissions and air pollutants.Four case studies, covering the United States, the European Union, China, and India, reveal the various opportunities, hurdles and limits of fuel switching as a way to address environmental challenges. Key findings Emissions savings After three flat years, global energy-related CO2 emissions resumed growth in 2017 and 2018, representing a dangerous disconnect with global climate goals…

How much will renewable hydrogen production drive demand for new renewable energy capacity by 2027?
…and specific targets for renewable hydrogen production, such as Inner Mongolia, which aims to produce 500 000 tonnes/yr of renewable hydrogen – more than twice the national target. Other key drivers are access to affordable financing through state-owned enterprises and to industrial clusters for new project development. Many new electrolyser projects are large demonstration plants located in industrial hubs that can offer economy-of-scale savings, lower unit manufacturing costs and access to local off-takers.Demand for renewable hydrogen, which is a forecast uncertainty, will determine the pace of dedicated renewable capacity expansion. While many provinces include hydrogen in…

Regional Energy Efficiency Policy Recommendations: Southeast Asia Region
Working with energy efficiency policy experts from ten countries in Southeast Asia, the IEA and partners including the Asian Development Bank, the Renewable Energy and Energy Efficiency Partnership (REEEP), the Ministry of Energy and Mineral Resources of Indonesia and the International Copper Association Southeast Asia (ICASEA) developed this set of twenty region-specific energy efficiency policy recommendations. These recommendations seek to help countries in Southeast Asia overcome barriers to energy efficiency uptake and realise the tremendous benefits of energy efficiency for their economies.
The IEA also worked with regional partners to develop energy efficiency policy recommendations for the Arab-Southern… -

Partner Country Series - Energy Use in the Chinese Building Sector
Energy and environmental impacts associated with the building sector in the People's Republic of China are significant, representing nearly 16% of total global final energy consumption in buildings. China has experienced unprecedented economic growth and buildings construction since 2000. There is a unique opportunity to drive investments with technological and policy initiatives leading the way towards a more sustainable buildings sector that can offset expected energy consumption growth. While China’s energy consumption per capita is still low by global standards, the total impact of energy use and emissions in the buildings sector – on the Chinese economy, on local…
