Energy efficiency indicators are an important tool for analysing the interactions among economic and human activity, energy use and CO₂ emissions. Many IEA member countries already employ energy indicators, a set of disaggregated measures of how energy is used.

About energy efficiency indicators

The IEA role is to assist and co-ordinate countries’ efforts through the maintenance of transparent international databases, the development of state-of-the-art energy indicators and collaboration with other international organisations.

Since 1997, the IEA has developed a series of energy indicators to study energy-use developments and analyse factors behind changes in energy use and CO2 emissions. Energy indicators (and the underlying databases) reveal key relationships among energy use, energy prices and economic activity. This insight is crucial when assessing and monitoring past and present energy policies, and for designing effective future action. This work on indicators also aims at increasing the transparency, quality, completeness and timeliness of energy-related data.

Energy Efficiency Indicators: Essentials for Policy Making

‌Energy efficiency is a growing policy priority for many countries around the world. It is widely recognised as the most cost-effective and readily available means to address numerous energy-related issues, including energy security, the social and economic impacts of high energy prices, and concerns about climate change. At the same time, energy efficiency increases competitiveness and promotes consumer welfare.

‌In this context, 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 (see below) 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 is high on the political agenda as governments seek to reduce wasteful energy consumption, strengthen energy security and cut greenhouse gas emissions. However, the lack of data for developing proper indicators to measure energy efficiency often prevents countries from transforming declarations into actions. 

The main objectives of Energy Efficiency Indicators: Fundamentals on Statistics are to identify the main sectoral indicators and the data needed to develop these indicators; and to make surveying, metering and modeling practices existing all around the world available to all.

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. The ultimate goal is to make improved energy efficiency not only a concept but a reality.
