Energy efficiency is key to ensuring a safe, reliable, affordable and sustainable energy system for the future. It is the one energy resource that every country possesses in abundance and is the quickest and least costly way of addressing energy security, environmental and economic challenges.
While energy efficiency policies are becoming a key part of the global energy market, there remains vast untapped potential and the IEA is working with countries all over the world to implement efficiency measures.
Average energy intensity improvements
In 2015, energy intensity improved by three times the average of the last decade. However, to reach the overall goal of limiting global warming to 2 degrees this pace needs to accelerate.
Energy efficiency is at the heart of the IEA's overall strategic focus. The IEA supports governments and international organisations in understanding and implementing energy efficiency policies by providing the highest-quality data, analysis and policy advice. The IEA also fosters knowledge exchange among all stakeholders through our training programs and research collaborations and works to support energy efficiency agendas at key global fora such as the G7 and G20.
