Global Energy Review 2026 Technology: Nuclear
In 2025, 3 GW of new nuclear capacity came online, with China, India and Russia each completing work on a new reactor. However, these additions were offset by the retirement of 3 GW of nuclear capacity, two-thirds of which was in Belgium. In total, global nuclear capacity remained at 420 GW at the end of 2025, with reactors in operation in over 30 countries. There were ten construction starts in 2025 – nine in China and one in Russia – with a total capacity of 12.2 GW. Over the past decade, 94% of nuclear reactors that started construction were of…

Global EV Outlook 2026 Electric vehicle batteries
Electric vehicle battery deployment Electric vehicle battery deployment grew by almost 30% in 2025 Electric vehicles (EVs) remained the primary source of global battery deployment, accounting for more than 70% of the total in 2025, slightly down from almost 80% in 2024. In 2025, EV battery deployment reached 1.2 TWh, an increase of almost 30% compared to 2024, and more than 7 times greater than in 2020. Light‑duty vehicles remained the dominant segment, representing more than 85% of the 2025 EV battery deployment. However, the fastest growth came from electric trucks, for which battery demand more than doubled – largely thanks…

World Energy Investment 2025 Southeast Asia
In the past, Southeast Asia’s rapid economic growth was mostly driven by fossil fuels but clean energy now accounts for almost half of energy investment Southeast Asia is a rapidly developing region, with GDP per capita increasing by more than 30% since 2015. During the last ten years, energy demand has increased by over 35%, with electricity demand rising by more than 60%. Driving this is a 12% increase in electricity access rates, growing consumption in industry, urbanisation and rising incomes creating demand for cooling and other appliances. Historically, this rising energy demand has been met by fossil fuels…

Global Methane Tracker 2026 Recent insights from methane emissions studies
Advances in measurement and data processing Methane detection has improved markedly in recent years by making better use of existing satellite arrays and launching new devices, improving airborne instrumentation and calibration, and deploying tower, stationary and handheld detectors more widely. Overall, detection limits have been optimised, coverage has broadened and observation times have increased. Meanwhile, advances in data processing have enhanced both the speed and the quality of analysis.These advances yield better coverage and sharper insights into the sources and scale of methane emissions. They also confirm that effective methane management requires multi-scale measurement frameworks that combine space…

Sheltering From Oil Shocks Road transport fuels
Road transport accounts for around 45% of global oil demand, ranging from a third in Korea up to two-thirds in some countries in Europe and Latin America. In advanced economies, passenger cars dominate road transport demand, accounting for around 60% of road energy use. Trucks make up most of the remainder. In emerging economies, there is also a significant role for two/three-wheelers (scooters, motorcycles and tricycles), which account for around 5% of road transport demand and are more numerous than cars in many countries. The share of energy use in medium and heavy freight trucks is also…
