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.

Global Trends chart for Energy Efficiency

Without efficiency gains energy demand in 2015 in IEA countries would have grown by 1% annually surpassing the 2007 peak. Instead, energy demand is 1% below 2000 levels.

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 Highlights 2016

Published: 9 December 2016

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 provides the first 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.
