This roadmap aims to increase understanding among a range of stakeholders of the applications that electricity and thermal energy storage technologies can be used for at different locations in the energy system. Emphasis is placed on storage technologies that are connected to a larger energy...

Policies that respond to climate change and other environmental issues will increasingly impact the development of the global energy sector. The transition to low-carbon economies will need to be carefully managed, as the provision of secure, affordable energy is critical for economic growth and...

Energy is essential for humanity to develop and thrive. In 2015, the new Sustainable Development Goals, adopted by 193 countries, included for the first time a target to ensure affordable, reliable, sustainable and modern energy for all, underscoring a new level of political agreement on the...

The ten Association of Southeast Asian Nations (ASEAN) countries are among the most dynamic parts of the global energy system and a rising force in international energy affairs. Thanks to its growing partnership with Southeast Asia, the International Energy Agency (IEA) has conducted regular...

In this inaugural annual report on energy investments around the world, the International Energy Agency (IEA) looks at the lifeblood of the global energy system: investment. The ability to attract and direct capital flows is vital to transitioning to a low-carbon economy while also maintaining...

The world’s largest energy consumer and producer as well as the top oil importer and carbon dioxide emitter, the People’s Republic of China is in the centre of the global energy landscape – and at a turning point towards a low-carbon future. There is an increasingly clear congruence of...

Energy efficiency is central to all global energy transitions. It is the world’s most available, secure and affordable energy resource and every government around the world has the power to further exploit efficiency for widespread benefit. Energy Efficiency 2017 is the global tracker...

The evidence is clear: energy efficiency has played, and continues to play, a large and valuable role in the sustainable development of the global economy. The energy demand that is avoided as a result of steady improvements in the efficiency of energy-using stock such as buildings, cars and...

Energy efficiency improvements over the last 25 years saved a cumulative USD 5.7 trillion in energy expenditures. This virtual supply of energy generates multiple benefits to governments, businesses and households, including greater energy security from reduced dependence on energy imports and...

Often called the “first fuel” of the global energy system, energy efficiency is one of the most important steps that any government can take to move towards a sustainable energy system. To check on the progress made on this front, the IEA Energy Efficiency Market Report tracks the core...
