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.

Energy Efficiency 2018
…missing opportunities to improve energy efficiency and today's policies are not delivering the full potential gains that are cost-effective and use current technology. This delayed action on energy efficiency ends up locking in inefficiencies that mean much stronger action needs to be taken in the future. 2.2 million barrels of oil per day If all countries had adopted the best passenger fuel economy standards. 16% of industry electricity use If all countries had adopted the strongest electric motor standards. $20 billion If everyone had purchased the top 10% most efficient refrigerators. The Efficient World Scenario So what…

Assessing Measures of Energy Efficiency Performance and their Application in Industry
Assessing Measures of Energy Efficiency Performance and their Application in Industry This paper explores different measures of energy efficiency performance (“MEEP”) and considers the importance of so-called boundary definitions when measuring energy performance, and how these affect the appropriateness of country comparisons to guide policy decisions.
The paper also addresses the limitations of both energy intensity and technology diffusion indicators as measures of energy efficiency performance. A case study on Japan’s iron and steel industry illustrates the critical role of proper boundary definitions for a meaningful assessment of energy efficiency in industry. -

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…

Energy Policies of IEA Countries: Japan 2016 Review
…of Japan has revised its energy policy in recent years to focus on further diversifying its energy mix (less use of fossil fuels, more reliance on renewable energy, restarting nuclear plants when declared safe) and curbing carbon emissions. Building on these plans, Japan has outlined ambitious goals to cut greenhouse gas emissions by 26% between 2013 and 2030. This emissions reduction commitment requires a balancing act between energy security, economic efficiency, environmental protection and safety. This IEA review of Japan’s policies highlights three areas that are critical to its success: energy efficiency, increasing renewable energy supply and restarting nuclear…

Energy Policies of IEA Countries: Japan 2008
…on market forces throughout the system could lead customers to choices that enhance security, raise economic efficiency and promote environmental protection. Particularly with respect to climate change goals – Japan is the world’s fifth-largest greenhouse gas emitter – strengthening the value on greenhouse gas emissions would help give consumers the appropriate signals they need to make the right choices. Enhancing energy savings through efforts aimed at particular sectors (sectoral approaches) could be a part of the overall policy mix, along with ongoing leadership in promoting energy efficiency. The government should continue to work to complement existing voluntary instruments with stronger…

Energy Policies of IEA Countries: Japan 1999
…Energy sector reform in the energy sector is an important component of overall policy on economic recovery. Increasingly, the market will be relied on to achieve a satisfactory outcome. Independent Power Producers have entered the electricity market since 1995. The report analyses anticipated further reforms to liberalise the market for extra-high-voltage consumers (28% of all supply) and to introduce accounting separation of the activities of the existing utilities. Approximately 90% of carbon dioxide produced in Japan is energy-related. Policy to reduce emissions from the energy sector is focused on drastic energy efficiency measures and on the promotion…

World Energy Outlook 2017: China
…a much cleaner energy mix. This new direction will have consequences that are no less significant for China and the world than its earlier period of energy-intensive development. China moves to a "new normal" Slowing pace of growth The pace of growth in China’s energy demand slows dramatically in the New Policies Scenario to around 1% per year, less than one-sixth the average that the country has experienced each year since 2000. This is due to the combined effects of structural shifts in the economy, strong energy efficiency policies and demographic changes: total energy demand growth to…

Prospects for Distributed Energy Systems in China
…s primary energy consumption structure is expected to shift in coming decades. This transition is an opportunity for the increased adoption of distributed energy systems. Against this background, it is timely to take stock of what distributed energy means in the 21st century, where its application in China stands today and what its future prospects are.This report aims to provide a step in this direction; it presents a vision for what distributed energy systems may look like: integrated solutions that intelligently combine clean-generation options with energy efficiency and solutions that focus on customer’s needs for energy services…
