…demand; with rising air‑conditioner ownership and increasing temperatures, this value rose to 7 GW in 2024 and could further rise to 12 GW in 2030 without further efficiency action. If India were to experience similar heatwaves as in recent years – with temperature anomalies of over 4°C – the additional peak load would amount to 47 GW. However, if all new air conditioners in India were highly efficient (e.g. through increased minimum energy performance standards), peak load during a heatwave could be reduced by almost 9 GW or about 20%, significantly decreasing the risk of blackouts or brownouts.

Ukraine’s Energy Security
…importance. While Ukraine made strong strides in rebuilding and strengthening the resilience of its energy system this past spring and summer, the situation remains fragile, and the risk of huge disruptions and widespread destabilisation remains – particularly as Russia expands the scope and sophistication of its attacks.This analysis builds on the IEA’s September 2024 report, Ukraine’s Energy Security and the Coming Winter. It provides an update on the latest developments through October 2025 and proposes key actions that Ukraine and its partners can take to address urgent energy security vulnerabilities this winter and bolster longer-term energy resilience…

How accelerating electrification could strengthen energy security in Southeast Asia
…energy demand has risen by around 40%, while electricity demand has grown even faster – twice as fast as overall energy use. Although renewables have increased significantly over the past decade, fossil fuels have continued to dominate, meeting over 70% of energy demand growth across this period, with oil accounting for nearly half of total energy consumption.Rapid energy demand growth and continued dependence on fossil fuels brings greater exposure to energy security risks. The region is increasingly reliant on imported fuels, deepening its exposure to price volatility and supply disruptions. The current energy crisis linked to the Middle East conflict…

From farms to fuel: Ukraine’s biomethane opportunity for energy security and European decarbonisation
…emissions gas. Home to the largest agricultural land area in Europe, Ukraine has the resource potential to become one of the continent’s leading biomethane producers, supplying both its domestic market and the EU via an already existing pipeline infrastructure.The first exports of biomethane come at a critical moment. Repeated Russian attacks on Ukrainian energy infrastructure have exposed the vulnerabilities of centralised energy supply. Although biomethane relies on the same gas distribution and transmission infrastructure as natural gas, its production is inherently more decentralised than domestic natural gas extraction, reducing exposure to disruptions affecting individual production sites. Biogas and…

Nuclear Power
…a new era for nuclear energy.
Power generation from the global fleet of nearly 420 active nuclear reactors is set to reach a record high in 2025 as Japan restarts production, maintenance works are completed in France, and new reactors begin commercial operations in various markets, including China, Europe, India and Korea. Meanwhile, more than 60 nuclear reactors are currently under construction – representing over 70 gigawatts (GW) of capacity – and governments’ interest in nuclear power is at its highest level since the oil crisis in the 1970s, reflecting efforts to bolster energy security, accelerate clean energy transitions and meet rising…

Hydroelectricity
…total.
More than 150 gigawatts (GW) of new hydro capacity is set to come online by the end of the decade, mostly in emerging and developing economies. As a result, electricity generation from hydropower is expected to increase by 7% between 2025 and 2030. However, its share in global electricity generation is poised to decrease slightly by 2030 as other energy sources, including solar PV and wind, see faster growth.
Annual capacity additions of pumped-storage hydropower are forecast to double by 2030. Pumped-storage hydro plants can provide both flexibility and storage, boosting energy security as electricity systems evolve.

How governments can best support consumers during this energy crisis
…gas and a range of energy-related commodities.As concerns over supply security have grown, prices have risen across several parts of the energy system, increasing pressure on household budgets, public finances and economic activity more broadly. In response, many governments have announced emergency measures to protect consumers from higher energy costs. The IEA has supported these efforts by launching its largest-ever release of emergency oil stocks, publishing a menu of demand-side measures that governments, businesses and households can take to shelter consumers from price pressures, and tracking the actions being taken through its new Energy Crisis Policy Response Tracker.So…

Energy System Resilience
Lessons learned from Ukraine Ensuring energy security encompasses both long-term and short-term dimensions. The long-term dimension involves securing sufficient infrastructure investment and diverse supply sources. The short-term dimension – resilience – focuses on systems’ ability to cope with events exceeding standard planning conditions. Since Russia’s full-scale invasion in 2022, Ukraine has worked to protect its energy sector and to increase its ability to withstand and rapidly recover from Russia’s attacks on its energy infrastructure. The report explores the lessons that Ukraine has been learning as it works to bolster system resilience and identifies measures that…
