Global Energy and Climate Model Techno-economic inputs
The Global Energy and Climate Model (GEC Model) uses macro drivers, techno-economic inputs and policies as input data to design and calculate the scenarios. The values for the different data categories and scenarios used in the GEC Model 2025 can be downloaded here.In particular more details regarding power generation technology costs for the Current Policies Scenario, the Stated Policies Scenario and the Net Zero Emissions by 2050 Scenario can be downloaded in excel format, including detailed projections at the 2050 horizon regarding overnight capital costs, annual O&M costs, efficiencies and other contributors to electricity costs at regional…

A new era for nuclear energy beckons as projects, policies and investments increase
As the world’s second-largest source of low-emissions electricity after hydropower, nuclear power today produces just under 10% of global electricity supply. Now, fresh momentum around the world has the potential to open a new era for nuclear energy.
Power generation from the global fleet of nearly 420 active nuclear reactors is set to reach a record high in 2025 as Japan restarts production, maintenance works are completed in France, and new reactors begin commercial operations in various markets, including China, Europe, India and Korea…

Global Hydrogen Review 2026
The IEA's Global Hydrogen Review 2026 provides an update on hydrogen production and demand worldwide and identifies the latest developments relating to policy, infrastructure, trade, investments and innovation.The report is an output of the Clean Energy Ministerial Hydrogen Initiative and is intended to provide an update to energy sector stakeholders on the status and future prospects of hydrogen, and to inform discussions at the Hydrogen Energy Ministerial Meeting organised by Japan.The conflict in the Middle East is impacting global supplies of hydrogen and hydrogen derivatives, such as fertilisers, exposing vulnerabilities in their supply chains. As energy security…

Gas Market Lessons from the 2022-2023 Energy Crisis
The 2022-2023 energy crisis tested the resilience of the global gas and LNG markets with the most severe gas supply shock in history. During the crisis, natural gas-importing markets around the world felt the pressures of record-high gas prices, including the scale-back in access to energy, the impediment to economic activity and the extra burden on government budgets. Market responses varied but governments were quick to react as the challenges of security of supply became apparent. Post-crisis, markets must continue to adapt as the effects of the crisis continue to influence security of gas supply…

Global Critical Minerals Outlook 2025 Overview of outlook for key minerals
Demand for critical minerals continues to rise across all scenarios, driven by the rapid deployment of energy technologies Demand for key energy minerals is set to grow rapidly across all scenarios, with the largest source of growth coming from the energy sector. In the Stated Policies Scenario (STEPS), lithium grows fivefold from today to 2040, while graphite and nickel demand double. Demand for cobalt and rare earth elements also grows strongly, increasing 50-60% by 2040. Copper is the material with the largest established market, and its demand is projected to grow by 30% over the same period. Battery deployment…

China’s Official Energy Finance in Emerging and Developing Economies Case 3. Saudi Arabia’s first green full-process heavy plate mill project
Project overview and impact Saudi Arabia is pursuing an ambitious industrial transformation under Vision 2030, including efforts to localise heavy industries, expand low-carbon manufacturing and diversify export capacity. Steel demand is expected to grow steadily due to investment in hydrogen, ammonia, shipbuilding, offshore engineering and large-scale infrastructure. However, the country currently imports nearly all of its heavy plate steel, and domestic production has lagged the needs of an economy shifting towards more capital-intensive sectors and cleaner industrial processes.A new heavy-plate complex developed jointly by China Baowu Steel Group, Saudi Aramco and the Public Investment Fund…

Switzerland
Switzerland has notably decoupled economic growth from energy use despite strong population growth. This trend should continue, and the energy efficiency first principle should be reflected in all climate and energy legislation. Reaching the 2050 net zero emissions target and addressing the growing winter electricity gap between demand and production requires an unprecedented volume of additional renewable generation capacity, especially wind and hydro. For this, the country needs to shorten the complex and extended administrative and legal permitting process. This will also help advancing investments in grid infrastructure to prepare for more decentralised and variable generation. Switzerland should also align…

State of Energy Policy 2026 Energy efficiency and fuel switching regulations
More than 130 countries have energy efficiency or fuel switching regulations in place, but some were revised, delayed or withdrawn in 2025 Energy use has become more efficient around the world since 2000. Global energy intensity has improved by around 30% over the past 25 years, meaning the world uses about 30% less energy per unit of economic output today than it did in 2000, with differentiated trends by key end uses: passenger cars and air conditioners have notably seen efficiency improvements for new sales of 30% and 45%, respectively since 2005. However, the pace of improvement has slowed over…

Denmark
Denmark has been an early leader in decarbonisation and in 2022 the government announced a net zero by 2045 target, aiming at 110% emissions reductions by 2050. Denmark’s technology leadership is important in the areas of offshore wind, biomethane and district heating. The government has expanded these categories to adopt a strategic focus on carbon capture and storage (CCUS) and hydrogen. The government has a robust energy and climate governance under the Danish Ministry of Climate, Energy and Utilities and ‘the year wheel’ of Climate Act of 2020 ensures annual policy actions and funding. Among IEA countries, Denmark has…
