Energy Security
The IEA has been at the heart of international energy security for 50 years – working to avoid, mitigate and manage energy disruptions and crises. While the Agency’s mandate initially centred on oil security, its work has since broadened to include the security of natural gas, electricity and clean energy supply chains.Threats to energy systems are constantly evolving. The IEA continually monitors and analyses these threats, including geopolitical risks, cyberattacks on energy infrastructure, supply chain disruptions and extreme weather events. On 24 and 25 April, 2025, the IEA convened an International Summit on the Future of Energy Security, hosted by the…

Outlook for Biogas and Biomethane
A global geospatial assessment Biogases play an important and growing role in energy systems. Produced locally using organic waste, biogas and biomethane can contribute to energy security, waste management, emissions reductions and agricultural development.In recent years, demand for biomethane – also known as “renewable natural gas” – has grown rapidly in many countries, supported by dozens of new policies. As a low-emissions substitute for natural gas, the use of biomethane has been targeted across a wide range of sectors, including power, industry, transport and buildings. This report presents a first-of-its-kind global geographical analysis of the untapped potential…

Global Methane Tracker 2026
Around the world, many countries have made reductions in methane emissions a policy priority as part of their efforts to limit near-term global warming, enhance energy security, and improve air quality. The energy sector – including oil, natural gas, coal and bioenergy – accounts for around 40% of methane emissions from human activity and has some of the best opportunities to cut these emissions. The annually updated Global Methane Tracker provides essential data on methane emissions across the energy sector and the opportunities to bring them down.The Tracker presents the IEA’s latest sector-wide emissions estimates – based on the…

World Energy Outlook 2025
The IEA’s flagship World Energy Outlook (WEO) is the most authoritative source of global energy analysis and projections. Updated annually to reflect the latest energy data, technology and market trends, and government policies, it explores a range of possible energy futures and their implications for energy security, access and emissions. The WEO covers the whole energy system, using a scenario-based approach to highlight the central choices, consequences and contingencies that lie ahead. It includes exploratory scenarios that flow from different assumptions about existing policies, as well as normative pathways that achieve energy and emissions goals in full. The multi…

Energy Efficiency Policy Toolkit Buildings
Introduction Buildings account for about 30% of final energy consumption globally and more than half of electricity consumption. Doubling the global annual energy intensity improvement by 2030 would require buildings to become more efficient rapidly. An integrated policy approach combining regulation, information and incentives is the most effective way to achieve this goal. Regulatory standards such as building energy codes are among the most effective policies to not only boost energy performance and reduce emissions, but also to improve occupants' health, comfort and productivity – while enhancing climate resilience and mitigating energy price fluctuations. Buildings built after a code is introduced can…

The next wave of LED lighting: Smarter, circular and more efficient
lighting commentary The first LED revolution reduced energy use worldwide – and a second wave of deployment is now taking shape As the world enters the Age of Electricity, lighting remains one of the most visible – and widespread – parts of our energy use.The IEA estimates that lighting in buildings and outdoor applications accounts for the majority of overall lighting electricity demand. In 2024, around 8% of global electricity demand – or about 2 200 terawatt hours (TWh) – was attributed to lighting in buildings and outdoor applications, excluding industry and agriculture. These figures reflect the latest available data and define the scope…

Global electric car sales continue to break records as affordability improves
Despite recent economic headwinds that have put pressure on the auto sector, global sales of electric cars have continued to break records as electric models become increasingly affordable. Electric car sales exceeded 17 million globally in 2024, reaching a sales share of more than 20%. Just the additional 3.5 million electric cars sold in 2024 compared with the previous year is more than the total number of electric cars sold worldwide in 2020.
In 2025, sales of electric cars are expected to surpass 20 million, accounting for over…
