Indonesia
Indonesia’s imports of oil have rapidly increased in recent years. This resource-rich nation is the world’s fourth-largest producer of coal and Southeast Asia’s biggest gas supplier. The country is the largest producer of biofuels worldwide and it is scaling up efforts to exploit its renewable energy potential. Indonesia's importance is underscored by its sizeable population of 250 million people – the fourth-largest in the world – and its significant role as a major producer and consumer of energy in regional and international markets. Indonesia is also the largest economy in ASEAN and an active member…

Ukraine
Ukraine is a key country for European and global energy security. Russia’s invasion of Ukraine has pushed it to fundamentally reshape its past dependence on energy imports from Russia.
As the invasion continues, Ukraine is focused on tracking large-scale energy supply disruptions and actively working to recover power and heating for civilians. It is also putting together an ambitious recovery and reconstruction plan, with a strong focus on energy security. In the medium-term, Ukraine’s energy strategy remains focused on European integration, while it aims to an energy system that is ready for a Net Zero future…- Overview

Critical Mineral Traceability for Energy and Economic Security
Amid rising risks linked to the high concentration of critical mineral supply chains, the ability to track where minerals originate, how they move through supply chains, who has custody of them and how they are transformed is increasingly important for policymakers seeking to create diversified and responsible supply chains.This report provides insights from a first-of-its kind survey on traceability conducted by the IEA and OECD. More than 80 respondent companies active across supply chains of the six focus minerals (copper, lithium, nickel, cobalt, graphite and rare earth elements) provided results between October and December 2025. Drawing on…

Pledges to Progress 2025 Recommendations
…from oil and gas production, the degree of cost-effectiveness in pursuing reductions, and the uptake among industry, investors and others suggest that all stakeholders are well aware of the opportunity for climate mitigation and operational efficiency.In many cases, large improvements in company scores could be achieved with better reporting and increased transparency, especially since companies are likely to be doing more than they are disclosing. This would also provide assurances to external stakeholders that the industry is turning its public pledges into action. Specific actions where improvements could make meaningful differences include:Encourage companies to sign the Oil…

Health
Multiple benefits of Energy Efficiency 2025 Energy efficiency provides multiple benefits. This page explores health. Why is energy efficiency important for health? Energy efficiency can improve health by creating healthy indoor and outdoor living environments with comfortable temperatures and humidity levels, and improved air quality. Key facts Energy efficiency measures have been linked to improved health, such as fewer respiratory illnesses.Targeted energy efficiency programmes can reduce doctor and hospital visits and save health costs. In New Zealand, a retrofit programme led to a 43% reduction in hospital admissions for respiratory conditions, while a similar programme in Ireland reduced the…

Energy Technology Perspectives 2026 Executive summary
…on average per year over the past decade, to reach nearly USD 1.2 trillion in 2025. In the Current Policies Scenario (CPS), their global market value grows most slowly, but it still doubles to around USD 2 trillion in 2035, about the size of the global crude oil market in 2025. At almost USD 3 trillion by 2035, their market value is higher in the Stated Policies Scenario (STEPS), with greater deployment offsetting the additional decline in costs. Electric cars are by far the largest clean energy technology market in 2035, accounting for around three-quarters of the total…

Global battery markets are growing strongly – and so are the supply risks
part 1- lithium-ion batteries Batteries’ importance is increasing across key sectors including autos, power, data centres and beyond The global lithium-ion battery market exceeded USD 150 billion in 2025, an increase of over 20% from 2024, but its economic and strategic significance extends far beyond market size. Batteries are becoming a cornerstone of the automotive sector, a critical source of flexibility for power systems, and an increasingly important source of back-up power for digital infrastructure, including data centres and artificial intelligence.Beyond energy, batteries remain indispensable for a wide range of industrial and strategic applications, from portable…

Norway
…establishing a low-emissions society by 2050. As an energy-rich country, Norway is in a unique starting position with respect to the energy transition. An abundance of affordable hydropower has enabled the development of energy-intensive industries and a high level of electrification of homes and businesses with limited greenhouse gas emissions. At the same time, as a major oil and gas producer and exporter, Norway will need to support an evolution of its energy sector amid the global energy transition. Altogether, Norway has the opportunity to lead the world in new technologies for decarbonising hard-to-abate sectors.

World Energy Outlook 2022 Outlook for gaseous fuels
…energy shortages in several parts of the developing world that rely on imported gas, notably Pakistan and Bangladesh. Major growth markets for gas such as India and China have meanwhile sharply reduced their LNG imports in 2022. Key findings The traditional arguments in favour of natural gas have focused on its role as a reliable partner for the clean energy transition and its ability to step in to fill the gap left by declining coal and oil. These are currently being tested by the global repercussions of Russia’s actions in Europe. In the midst of a global energy crisis…
