Energy Efficiency Statistics

To inform and monitor the effectiveness of energy efficiency policies, reliable end-use data and indicators are key: they help to explain what drives the demand for energy. Indicators are an important tool for measuring progress, comparing the success of different policy measures and allow us to project energy efficiency potential for the future.

Statistics on Energy Efficiency

Key World Energy Statistics 2017

2017 marks the 20th edition of the Key World Energy Statistics (KWES) – the annual booklet of the IEA’s most used statistics. This milestone’s edition has been enriched with more information on energy efficiency and renewables, more geographic data and also more of the fundamental data required to fully understand energy security.

Key World Energy Statistics contains timely, clearly presented data on the supply, transformation and consumption of all major energy sources for the main regions of the world, proving everyone with an interest in energy key statistics on more than 150 countries and regions including energy indicators, energy balances, prices, RDD and CO2 emissions as well as energy forecasts.

All of the data in the booklet will also be available in app form for all major mobile devices.

Energy Efficiency Indicators Highlights 2016

Energy Efficiency Indicators Highlights 2016 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..

For Statisticians and Policy Makers

Energy Efficiency Indicators: Essentials for Policy Making

It is important to develop and maintain well-founded indicators to better inform policy making and help decision makers formulate policies that are best suited to domestic and/or international objectives. Yet choosing and developing appropriate indicators to support the development of policies is not straightforward. Energy Efficiency Indicators: Essentials for Policy Making and its companion document are intended to provide the necessary tools to initiate and/or further develop in-depth indicators to support the decision-making process.

Energy Efficiency Indicators: Fundamentals on Statistics

Energy Efficiency Indicators: Fundamentals on Statistics identifies the main sectoral indicators and the data needed to develop these indicators, sharing best practice on surveying, metering and modelling techniques. This manual has been developed with a companion document, Energy Efficiency Indicators: Essentials for Policy Making, as a starting point to enable policy makers to understand where greater efficiency is needed, to implement appropriate policies and to measure their impact.




Energy Efficiency Indicators Statistics: Country Practices Database

A supplement to the publication Energy Efficiency Indicators: Fundamentals on Statistics, this database explores best practices from a variety of OECD Members and non-Members for the collection of data and the development of efficiency indicators. Practices are searchable by country and territory, sector, methodology and type of available documentation. By sharing these experiences, we hope to help countries and organisations to develop their own energy efficiency indicators programs.
