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..
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 at the IEA
Energy efficiency is at the heart of the IEA's overall strategic focus. Through analysis, policy guidance and knowledge exchange among all stakeholders, the IEA supports governments around the world in understanding and implementing energy efficiency policies. We are committed to providing the highest-quality data, analysis and policy advice in order to help countries deliver on the immense potential of energy efficiency.
The IEA provides quality analysis on the progress, drivers and impacts of energy efficiency through publications such as the Energy Efficiency Market Report. Supporting best practice, the IEA is accelerating the implementation of effective energy efficiency policy in buildings, appliances, transport, industry and lighting.
By 2040, more than 95% of growth in primary energy demand will occur outside OECD countries and the majority of consumption will be in a small number of emerging economies. Improving energy efficiency in these countries is therefore more important than ever. Through the IEA's Energy Efficiency in Emerging Economies (E4) Programme, we are collaborating to scale up and capture the benefits of energy efficiency in a number of target emerging economies, through country-specific analysis, hands-on support and multi-country engagement, shared learning and capacity building.

Benefits of Energy Efficiency
Energy efficiency is often defined as achieving the same services with less energy. This definition grossly understates the power of energy efficiency to provide benefits beyond energy savings for society and for the economy.
