                Global Energy Review 2025 OilOil

                Oil demand growth loses momentum Growth in global oil demand slowed markedly in 2024, with consumption rising by 0.8% (1.5 EJ or 830 kb/d) to 193 EJ after jumping by 1.9% in 2023. This reflected the end of the post-pandemic mobility rebound, slower industrial growth and the increasing impact of electric vehicles. This 0.8% increase in demand – below the pre-pandemic growth rate of over 1% in the decade to 2019 – was closely in line with the IEA’s first forecast for 2024 set out in June 2023, which noted that structural macroeconomic trends would…

                New Zealand

                New Zealand has a diversified energy mix, with significant production of both hydropower and geothermal. As the country embarks on an ambitious energy transition, it has many natural advantages, including a strong renewable resource base. New Zealand already has a low-emissions electricity system, with over 80% of electricity coming from renewable sources. The key challenge will be to decarbonise other end-use sectors through clean power and support investments in new technologies to achieve deeper emissions cuts across all sectors. Notably, the transport sector accounts for the highest share of emissions and is almost entirely dependent on oil while…

                India is working to diversify its power generation mix by promoting investment in renewables and nuclear to meet sharply rising electricity demand Electricity demand in India has been rising sharply due to increases in commercial and residential space, a surge in ownership of air conditioners and appliances, and rising demand from industry. India has seen the third-largest growth in power generation capacity in the world after China and the United States over the past five years. While growth in power generation has come from all sources, there has been a surge in investment in renewables, led by solar PV…

                Integrating Solar and Wind in Southeast Asia Executive summaryExecutive summary

                Southeast Asia stands at a pivotal moment to leverage abundant renewable resources and meet growing demand Electricity demand in Southeast Asia is rising at one of the fastest rates globally, highlighting the importance for all countries to diversify their energy sources. Driven by rapid urbanisation, population growth, industrialisation and rising living standards, demand growth exceeded 7% in 2024 - nearly double the global average. While the Association of South East Asian Nations (ASEAN) member states are becoming increasingly reliant on imported coal and gas for power generation, the recent global energy crisis underscored the risks that this dependence poses through fuel…

                Global Methane Tracker 2026 Key findingsKey findings

                No sign that global energy-related methane emissions fell in 2025 despite progress in some areas The fossil fuel sector accounts for around 35% of methane emissions from human activity, yet there is still no sign that methane emissions from fossil fuel operations are falling, despite well-known and proven mitigation pathways. Oil, gas and coal production output reached record highs in 2025, and the International Energy Agency (IEA) estimates that methane emissions from these activities total 124 million tonnes (Mt) a year: oil is the largest source at 45 Mt, followed by coal at 43 Mt, and natural gas at 36 Mt.

                The role of coal in power systems is evolving This report assesses the potential applications, limitations and relevance of transition credits in Southeast Asia. Coal is the largest source of power generation worldwide and the largest source of energy-related carbon dioxide emissions. All Southeast Asian countries with coal in their power generation mix have adopted commitments to reduce coal-fired generation or emissions targets that imply a significant decline in coal consumption in the coming decades. To meet these targets, the International Energy Agency (IEA) has long emphasised that a range of strategies can be deployed to reduce coal…

                Electricity Mid-Year Update 2025 Emissions: Power generation CO2 emissions are plateauingEmissions: Power generation CO2 emissions are plateauing

                Global emissions from electricity generation rose by 1.2% in 2024, following an increase of 1.6% in 2023. Last year was even hotter than in 2023 – making it the warmest year on record – with the heat waves boosting electricity demand for cooling. Nonetheless, growth in power sector emissions showed signs of slowing down as rapid deployment of renewables constrained increases in fossil-fired generation. As this trend continues, we expect 2025 emissions to plateau and remain relatively unchanged. In 2026, we forecast a slight decline of less than 1%, as the increase in low-emissions generation depresses fossil-fired…

                Evolving generation and demand patterns reshape power system needs The Age of Electricity is underpinned by rising investments in new resources. These include growing converter-based variable solar PV and wind, battery storage systems, as well as spatially and temporally concentrated demand from EVs, heat pumps and large loads like data centres. Combined with the expansion and upgrade of transmission and distribution grids, substantial increases in the flexibility of power systems are required for secure and cost-effective integration of generation, load and storage technologies that characterise this new era.Last year’s report, Electricity 2025, focused on measures to…

                Gaining an Edge Summary for policymakersSummary for policymakers

                Energy efficiency delivers more than energy savings and emission reductions – it can also improve the competitiveness of countries and firms. From increased profitability to job creation, energy efficiency helps firms compete amid high costs, growing demand, and rising trade pressures. In today’s global context, energy efficiency is not only a matter of energy policy, but also of economic policy.Today the world’s industries can produce nearly 20% more value for a given amount of energy than they could two decades ago. This progress has yielded significant benefits at the country level. G20 countries have doubled their economic output…
