Benefits of Energy Efficiency
The term "multiple benefits" aims to capture a reality that is often overlooked: investment in energy efficiency can provide many different benefits to many different stakeholders. In other literature, the multiple benefits of energy efficiency have been variously labelled "co-benefits", "ancillary benefits" and "non-energy benefits" – terms often used interchangeably with “multiple benefits”. The IEA uses the term multiple benefits, which is broad enough to reflect the heterogeneous nature of outcomes of energy efficiency improvements and to avoid pre-emptive prioritisation of various benefits; different benefits will be of interest to different stakeholders.
The IEA's Efficiency Exchange Platform contains up-to-date information on the multiple benefits, including reports and case studies.
Capturing the Multiple Benefits of Energy Efficiency
Published: 11 October 2014
The IEA study of the multiple benefits of energy efficiency seeks to expand the perspective of energy efficiency beyond the traditional measures of reduced energy demand and lower greenhouse gas (GHG) emissions by identifying and measuring its impacts across many different spheres. By revealing the potential of energy efficiency to support economic growth, enhance social development, advance environmental sustainability, ensure energy-system security and help build prosperity, this work repositions energy efficiency as a mainstream tool for economic and social development.
Early investigations of these multiple benefits suggest that they are significant, however they are left out of most policy and programme evaluations for various reasons, including lack of relevant data and evaluation methods, estimation challenges and perceived credibility risk.
A multiple-benefits perspective helps to understand the impacts, as well as the sources and causes, of an observed rebound effect and accordingly to manage better any trade-offs that might take place.
This publication was supported by a two-year research programme including broad consultation with a range of international experts who make up the Multiple Benefits Network and a series of expert roundtable discussions on several key benefits areas in order to share experience, discuss issues and challenges, and assemble good practice policy and evaluation approaches.
