Household Energy Affordability Executive summary
…10-30% above pre-crisis levels in real terms. North America, by contrast, saw residential natural gas prices rise by around 5% in 2025, though they remain well below prices in Europe and other importing regions.The prices paid by households for energy vary widely from country-to-country, reflecting not just the cost of supply but also various additional levies, taxes and subsidies. For gasoline, taxes can account for as much as 70% of the final price charged to consumers, as is the case in some countries in Europe. It can also be subsidised and delivered at prices below…

Emission reductions
Multiple benefits of Energy Efficiency 2025 Energy efficiency provides multiple benefits. This page explores emission reductions. Why is energy efficiency important for emission reductions? Energy efficiency can reduce emissions of greenhouse gases and air pollutants and make the energy system more sustainable. Key facts Since 2010, efficiency measures avoided energy-related carbon dioxide (CO₂) emissions equivalent to nearly 20% of the global total in 2023. This is more than the entire energy-related emissions of India and the European Union combined. Accelerating efficiency improvements could deliver a third of all energy-related CO₂ emission reductions between now and 2030 in…

Sodium-ion battery momentum grows, but challenges remain
batteries commentary sodium batteries Recent technological advances and investment announcements suggest dynamics are shifting for sodium-ion batteries Sodium-ion batteries are emerging as a new player in battery markets, offering opportunities to diversify battery chemistries and supply chains at a time of rising global demand for electric vehicles and energy storage. Developed in laboratories since the early 1980s, sodium-ion batteries operate on the same fundamental principles as lithium‑ion batteries – which currently dominate the market – yet their path to commercialisation has been markedly slower.While lithium-ion batteries entered commercial use in the 1990s – with the first electric vehicles…

Oil Market Report - March 2025
The IEA Oil Market Report (OMR) is one of the world's most authoritative and timely sources of data, forecasts and analysis on the global oil market – including detailed statistics and commentary on oil supply, demand, inventories, prices and refining activity, as well as oil trade for IEA and selected non-IEA countries. Highlights Growth in global oil demand is set to accelerate to just over 1 mb/d this year, from 830 kb/d in 2024, reaching 103.9 mb/d. Asia accounts for almost 60% of gains, led by China where petrochemical feedstocks will provide the entirety of…

Businesses see competitive value of energy efficiency, but smaller firms struggle to access solutions
…energy efficiency, but SMEs struggle to benefit Energy efficiency is a strategic asset for industrial competitiveness. For companies facing tight margins, volatile energy prices and intensifying global competition, reducing energy waste is not only a cost-saving measure, but also a way to protect productivity, manage risk and strengthen their position in global markets. Yet not all firms have the same capacity to quickly improve their energy efficiency.New analysis of the 2025 IEA Industrial Competitiveness Survey – which covered 1 000 companies across 14 countries – shows that business leaders view energy efficiency as closely linked to their competitive performance. But the…

…natural gas and electricity. The scale of China’s future electricity demand and the challenge of decarbonising the power supply help explain why global investment in electricity overtook that of oil and gas for the first time in 2016, and why electricity security is moving firmly up the policy agenda. That said, cost reductions for renewables are not sufficient on their own to secure efficient decarbonisation or reliable supply.
Between 2019 and 2024, China will account for 40% of global renewable capacity expansion, driven by improved system integration, lower curtailment rates and enhanced competitiveness of both solar PV and onshore…- Overview

Investment in next-generation geothermal is surging. Policies are key to further growth
Next-generation geothermal readies for take-off Next-generation geothermal is seeing a burst of financing, innovation and new supply agreements Geothermal energy harnesses naturally occurring heat found beneath the Earth’s surface to provide heating and cooling, electricity and energy storage. As global electricity demand rises and power systems place a growing premium on firm supply, geothermal energy’s ability to provide an around-the-clock, low-emissions source of power is attracting renewed attention. However, easy-to-access conventional geothermal resources are relatively rare and mostly confined to a small number of shallow geothermal hotspots globally, accounting for…

…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 the highest share of wind electricity…
