Global Energy and Climate Model About the Global Energy and Climate Model
Overview Since 1993, the IEA has provided medium- to long-term energy projections using a continually evolving set of detailed, world-leading modelling tools. First, the World Energy Model (WEM) – a large-scale simulation model designed to replicate how energy markets function – was developed. A decade later, the Energy Technology Perspectives (ETP) model – a technology-rich bottom-up model – was developed for use in parallel to the WEM.Over the past four years, the IEA has worked to develop a new integrated modelling framework: the IEA’s Global Energy and Climate (GEC) Model. This model is now the principal tool…

Gas Market Report, Q3-2025 Executive summary
Following a slowdown in 2025, global gas demand growth is forecast to accelerate in 2026 Global natural gas demand returned to structural growth in 2024 and continued to expand in the first half of 2025, albeit at a markedly slower pace. Growth was primarily concentrated in Europe and North America, with adverse weather leading to stronger gas use in the buildings and power sectors. In contrast, gas demand was subdued in Asia, with both China and India recording demand declines in the first half of 2025. Market fundamentals remained tight in the first half of 2025 due to a combination…

Global Energy and Climate Model Stated Policies Scenario (STEPS)
The Stated Policies Scenario (STEPS) has a long pedigree in the International Energy Agency (IEA) family of scenarios. It was introduced in 2019 with this name, but it has much in common with the previous New Policies Scenario that dates back to the 2010 edition of the World Energy Outlook (WEO). The intention of this scenario is to reflect the prevailing direction of travel for the energy system based on a detailed reading of the latest policy settings in countries around the world. It takes into account specific energy, climate and related industrial policies that have been adopted or put…

Wired for water: How electrification is transforming desalination
Wired for water: how electrification is transforming desalination The water-energy nexus Pressure on water resources is increasing worldwide and can be very acute at the local level. Rising consumption across sectors combined with population growth in already water-stressed regions is intensifying water scarcity. Desalination has long been developed to supply fresh water in the most affected areas, with significant implications for the energy system: energy use ranges from under 0.1% to as much as 15% of total final consumption, depending on national reliance. However, a shift is underway from thermal desalination technologies to electricity-driven systems as…

Energy and AI Understanding the energy-AI nexus
Artificial intelligence (AI) has a long history, dating back to at least the 1950s. Over time, it has seen a series of alternating periods of optimism and pessimism (so-called “AI winters”). In recent years, however, AI has been dramatically boosted by several developments and breakthroughs in techniques, costs and technology that have led to the rise of AI in its modern form that we are familiar with today, in particular generative AI. These developments include the massive increase in computing power and decline in cost due to exponential improvements in computing hardware performance; the exponential increase in the availability…

Net Zero Emissions
An increasing number of countries have been making pledges to reduce their emissions to net zero in the coming decades. To inform these efforts, the IEA released a first-of-its-kind Net Zero Roadmap in 2021, outlining what would be required within the energy sector to achieve this goal at the global level by mid-century. An update to the Roadmap, which has served as an essential benchmark for policy makers, industry, the financial sector and civil society, was published in 2023.The Roadmap is based on the IEA’s Net Zero Emissions (NZE) Scenario, which portrays a pathway for the…

World Energy Investment 2025 Africa
Africa is faced with new challenges and opportunities as the composition and source of investment flows in the continent shift Africa is characterised by strong regional imbalances. South Africa and North Africa account for less than 20% of the population but more than 45% of energy investment and over 65% of installed electrical capacity. By contrast, Sub-Saharan Africa, home to most of the region’s population, receives less energy investment and has limited access to reliable electricity. New connection rates have steadily increased since 2000 but remain well below the universal access target set for 2030, with 600 million…

Renewables 2025 Biogases
Policy attention to biogas and biomethane has increased significantly in the past five years Since 2020, more than 50 new policies have been introduced around the world, as more countries recognise the potential role of biogas and biomethane in the transition to sustainable energy systems. Several key factors are driving this surge. First is the growing importance of energy security following the energy crisis triggered by Russia’s invasion of Ukraine and recent geopolitical developments. Second is the need to accelerate decarbonisation in hard-to-abate sectors, together with growing emphasis on methane emissions reductions. Third, countries are paying more…

Decarbonization plan for the electrical system
The government released a plan detailing the coal phase out of the electrical system, a technology that adds up to over 5 GW of installed capacity in Chile. The plan is made in agreement with the coal-fired plant owners/operators. The objective is to phase out or reconvert all coal-fired power plants no later than 2040. The first phase, planned to be completed by 2024, will decomission 11 units (31% of installed capacity, 1731 MW).

Energy Ministry Decree No.77k/MB.01/MEM.B/2022
This decree stipulates the National Mineral and Coal policy which includes the inventory of minerals and coal, the management and utilisation of coal, mineral and coal conservation, as well as monitoring and evaluation. This National Mineral and Coal policy is dynamic and can be changed periodically for continuous improvement while supporting medium- and long-term national development.
