Energy Transition Review for Enhancing Co-operation
The Philippines’ power sector This report is part of ongoing IEA collaboration with Asia Zero Emission Community (AZEC) partners to better understand the particular challenges these partners face in their energy transition and to provide a platform for co-operation among the AZEC partners. The report seeks to build a shared understanding of the challenges and opportunities facing the Philippine power sector, and to identify practical pathways that can help to strengthen its energy security, improve affordability and enable the country to achieve its long-term clean energy goals.This review has been prepared in collaboration with the Department of Energy…

Financing the Modernisation of Power Systems Beyond Coal
The role of transition credits in Southeast Asia Coal is a central component of power systems in Southeast Asia, even as governments have committed to reducing coal‑related emissions. Rapid electricity demand growth, alongside coal’s role in system adequacy, reliability and energy security, complicates efforts to accelerate coal transitions. Recent volatility in international gas markets has reinforced the short‑term economic and security value of existing coal assets, adding complexity to national transition strategies. The region’s young coal fleet also implies substantial long‑term emissions if plants continue operating at current utilisation rates.Against this backdrop, new approaches are being explored…

Hydroelectricity
Hydropower is the largest source of renewable energy today, but that could change soon
Hydro is currently the third largest source of power generation worldwide after coal and natural gas. In 2024, it generated around 4 500 terawatt-hours of electricity, or 14% of the global 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…

Wind
Wind has significant potential to boost growth in global renewable capacity
Electricity generation from renewables is expected to increase by 60% through 2030 – rising from 9 900 terawatt-hours (TWh) in 2024 to 16 200 TWh by the end of the decade. Wind accounts for almost a third of growth, second only to solar PV, which accounts for 60%.
Although wind power continues to face supply chain issues, rising costs and permitting delays today, global capacity is still expected to nearly double to over 2 000 gigawatts (GW) by 2030 as both advanced and developing economies tackle these barriers.

Electricity Market Design
Building on strengths, addressing gaps Electricity markets play a central role in balancing supply and demand, guiding operational decisions and shaping investment outcomes. As systems change with higher shares of variable generation, greater decentralisation and evolving patterns of electricity use, the ability of market designs to deliver secure and affordable electricity has never been more critical. If market arrangements do not keep pace with these developments, the functioning of electricity systems could become more uncertain and more costly.This report provides a cross-regional assessment of how wholesale electricity markets and their complementary policy mechanisms are performing today. We find…

The Value of Demand Flexibility
Benefits beyond balancing This policy brief, developed under the International Energy Agency’s Digital Demand-Driven Electricity Networks (3DEN) Initiative, examines the value of demand flexibility as a core component of modern electricity systems, with a strong emphasis on its role in improving energy efficiency. As electricity demand grows and power systems become more electrified, decentralised and renewable-rich, managing when and how electricity is used is increasingly as important as expanding supply.The brief sets out a clear framework for understanding demand flexibility and highlights its contribution to an efficiency-first approach to power system planning and operation. By…

Overview graphic: key technology trends for EVs
GEVO 2026 - Chapter 8 Electric vehicles (EVs) are increasingly at the centre of innovation in the automotive sector, bringing advances that extend far beyond developments in batteries and power electronics, thanks to several mutually reinforcing factors. Key technology trends are aligning in favour of EVs Battery electric vehicles (BEVs) are mechanically simpler than internal combustion engine vehicles (ICEVs) or hybrids, making them more compatible with digitalisation and automation. The relative simplicity of electric drivetrains enables shorter development cycles for new vehicles, allowing emerging technologies to reach BEVs sooner than vehicles with other powertrains.While the transition from mechanical to software…

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…

Delivering on the EU’s electrification ambitions
EU paper The EU has ambitious goals for electrification Electrification is a key pillar of the EU’s energy security, industrial competitiveness, and climate strategy. Today, imported fuels account for around 60% of the EU’s total energy demand and cost the bloc EUR 380 billion in 2024. The risks associated with the EU’s reliance on fuel imports have been highlighted by recent market disruptions linked to the near-closure of the Strait of Hormuz amid the conflict in the Middle East, bringing renewed attention to the EU’s target of increasing electrification from 24% today to 32% of…

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…
