Key messages
2016 confirmed the recent step up in global energy efficiency gains

This is generating economic, social and environmental benefits• Energy intensity improvement is the main reason energy related emissions have levelled off• Because of energy efficiency, global energy use was 12% lower in 2016, resulting in global
economic gains and significant savings for households

• Decarbonisation requires the integration of efficiency and renewables into theenergy system through a harmonised policy approach.
• The IEA is helping countries realise unmet energy efficiency potential by training
policy makers, facilitating knowledge sharing and providing policy advice.
