Global Energy Review 2026 Technology: Battery storage
Battery storage is the fastest growing power technology today. In 2025, 108 GW of new battery storage capacity was deployed worldwide, 40% more than in 2024. Installed capacity is now eleven times higher than in 2021. Lithium‑iron phosphate (LFP) batteries now account for around 90% of deployments; while less energy‑dense than rival chemistries commonly used in EVs, LFP batteries are typically cheaper and better suited to more frequent cycling. Just five years ago, the market share of LFP batteries in deployments was well below 50%. Around 80% of new battery capacity in 2025 was utility‑scale. The remainder was behind-the…

More stringent and broader coverage of fuel efficiency standards for light-duty vehicles is needed
For cars and vans, increasing fuel efficiency standards is important as even in the Net Zero Emissions by 2050 Scenario, nearly 80% of cars and vans on the road in 2030 are still powered with internal combustion engines. Sales of heavier, less efficient SUVs reached around 46% of global sales in 2022, while electric vehicles were just 14% of sales. More and more countries are formulating vehicle efficiency standards and some are even putting in place zero-emission vehicle sales requirements. To be in line…

Energy security
Multiple benefits of Energy Efficiency 2025 Energy efficiency provides multiple benefits. This page explores energy security. Why is energy efficiency important for energy security? Energy efficiency can help mitigate energy security risks by reducing the reliance on fossil fuel imports, improving grid reliability, and acting as a buffer to supply shocks. Key facts Efficiency gains from the last two decades avoided the need for 20% more fossil fuel imports in IEA countries. Energy efficiency and demand response can support grid reliability by reducing peak demand. For instance, more efficient air conditioners in India could lower the impact of heatwaves on…

Scaling Up Demand Flexibility
From peak management to efficient system operation This report has been developed as part of the International Energy Agency (IEA) Digital Demand-Driven Electricity Networks (3DEN) initiative to examine the growing importance of demand flexibility in electricity systems amid rising demand, increased renewable energy integration and the electrification of power systems. Case studies in chronological order to examine the changing role of demand flexibility over time from South Africa (2025), Thailand (2030) and Ireland (2035) demonstrate how demand flexibility improves reliability, reduces costs, supports renewables integration and manages network constraints. To realise these benefits, the report emphasises the role for…

What Next for the Global Car Industry Present and future prospects of electric car manufacturing
Highlights New market-entrants focusing on electric car production are expanding rapidly. Pure-play electric car makers, especially those from China and US-based Tesla, are capturing a growing share of sales; some 45% of global electric car sales in 2024 are from pure-play electric car makers, compared to 35% in 2019. The growth in electric car sales affects both car makers and automotive suppliers, especially those producing powertrains and related components. The automotive supplier market is worth about USD 1.3 trillion, equivalent to over 40% of the global car market. For all components except batteries, companies from…

Gas Market Report, Q1-2026
Natural gas markets continued to rebalance in 2025. Global LNG supply returned to double-digit growth in the second half of the year, supported by the ramping-up of new LNG liquefaction projects in the United States, Canada and Africa. This strong growth is gradually easing market fundamentals and contributing to a more secure and resilient global gas market.Global LNG supply growth is set to accelerate further in 2026, fostering a stronger increase in natural gas demand, which is expected to reach a new all-time high. Although the LNG supply growth is reducing market tightness, geopolitical tensions and…

Brazil
Brazil’s energy policies measure up well against the world’s most urgent energy challenges. Access to electricity across the country is almost universal and renewables meet almost 45% of primary energy demand, making Brazil’s energy sector one of the least carbon-intensive in the world. Total primary energy demand has doubled in Brazil since 1990, led by strong growth in electricity consumption and in demand for transport fuels on the back of robust economic growth and a burgeoning middle class.
Large hydropower plants account for around 80% of domestic electricity generation, making the Brazilian electricity mix one of…- Overview

Global EV Outlook 2025 Executive summary
Electric car sales continue to break records globally, particularly in China and other emerging economies Electric car sales exceeded 17 million globally in 2024, reaching a sales share of more than 20%. Just the additional 3.5 million electric cars sold in 2024 compared with the previous year is more than the total number of electric cars sold worldwide in 2020. China maintained its lead, with electric cars accounting for almost half of all car sales in 2024; the over 11 million electric cars sold in China last year were more than global sales just 2 years earlier. As a result of…

Electricity Mid-Year Update 2025 Demand: Global electricity use to grow strongly in 2025 and 2026
Global electricity demand is forecast to increase by an average annual 3.3% in 2025 and by 3.7% in 2026, a moderation from 4.4% in 2024 but still some of the highest growth rates observed over the last decade. This is a slight downward revision from our previous forecast in February 2025 of 4% growth for this year and 3.8% in 2026. The change is partly due to the IMF's downgrade of the global GDP growth outlook compared with its January 2025 update amid elevated uncertainty surrounding trade tariffs and economic prospects. Despite these downside risks…
