Global Trends in Energy Efficiency
The IEA collects and analyses data to determine key international trends relating to energy efficiency. At the forefront of this work is the IEA’s annual Energy Efficiency Market Report, which highlights key global trends and indicators of energy efficiency. Analysis also covers energy efficiency policies and finance, trends in major economic sectors and the policies, progress and potential in IEA member and non-member economies.
Energy efficiency gains since 2000 helped households in several major economies avoid nearly $300 billion in additional spending on energy in 2016.

Energy Efficiency 2017
Published: 5 October 2017
Energy efficiency is central to all global energy transitions. It is the world’s most available, secure and affordable energy resource and every government around the world has the power to further exploit efficiency for widespread benefit. Energy Efficiency 2017 is the global tracker examining the trends, indicators, impacts and drivers of energy efficiency progress.
Energy Efficiency Market Report 2016
Published: 10 October 2016
The role of energy efficiency in the global energy transition is examined in the IEA’s Energy Efficiency Market Report 2016, which finds that its importance cannot be overstated. The 2016 report presents analysis of energy efficiency trends, indicators, policy and price drivers, the market for energy efficiency services, plus a special feature focused on energy efficiency in China.
Energy Efficiency Market Report 2015
Published: 21 October 2015
The Energy Efficiency Market Report 2015 evaluates the impact of energy efficiency in the energy system and assesses the scale and outlook for further energy efficiency investment using detailed country-by-country energy efficiency indicator data and IEA expertise. The report includes an in-depth look into the buildings energy efficiency market and the electricity sector.
Energy Efficiency Market Report 2014
Published: 17 September 2014
The Energy Efficiency Market Report 2014 provides an in-depth look at energy efficiency developments in the transport sector, finance, the growing scale and diversity of energy efficiency products and reviews national energy efficiency market developments in various jurisdictions including Canada, China, the European Union, India and Italy. These case studies provide snapshots of specific energy efficiency sub-markets, and insights into how these markets may evolve.
Energy Efficiency Market Report 2013
Published: 1 October 2017
This first Energy Efficiency Market Report provides a practical basis for understanding energy efficiency market activities, a review of the methodological and practical challenges associated with measuring the market and its components, and statistical analysis of energy efficiency and its impact on energy demand. It also highlights a specific technology sector in which there is significant energy efficiency market activity, in this instance appliances and ICT. The report presents a selection of country case studies that illustrate current energy efficiency markets in specific sectors, and how they may evolve in the medium term.
Energy Efficiency Indicators
Energy Efficiency Indicators Highlights 2017
Published: 1 December 2017
This statistical report is designed to help understand what drives final energy use in IEA member countries in order to improve and track national energy efficiency policies. It is the second edition of a comprehensive selection of data that the IEA has been collecting each year, after its member states recognised in 2009 the need to better monitor energy efficiency policies.
This publication is complemented by the new Energy Efficiency Indicators database, which contains annual data from 2000 to 2015, covering end use energy consumption by energy product, end use energy efficiency indicators, and carbon intensity indicators for the four sectors.
Energy Efficiency Indicators Highlights 2016
