Energy Technology Perspectives 2026

Why It Matters

The report reveals that China’s dominance and supply‑chain fragilities could jeopardize billions in clean‑energy investments, prompting governments to act now to secure economic and climate objectives.

Key Takeaways

• Clean energy tech market surpasses $1 trillion, projected to double
• Mass manufacturing drives cost declines and policy flexibility worldwide
• China dominates supply chains, supplying over 70% of key components
• One‑month Chinese battery export halt could halt $17 billion electric‑car production
• Addressing competitiveness gaps essential for energy security and climate goals

Summary

The International Energy Agency unveiled its 2026 Energy Technology Perspectives report, a flagship analysis of clean‑energy technology supply chains and market dynamics. The launch highlighted a shift from climate‑driven adoption to pure market opportunity, with the global clean‑energy technology market exceeding $1 trillion last year and projected to double to roughly $2 trillion by 2035 under current‑policy scenarios. Key findings show mass manufacturing and falling component costs have unlocked unprecedented demand for solar PV, wind, batteries, electric vehicles and heat pumps. Yet investment in new manufacturing capacity peaked at $200 billion in 2023 and is now receding, creating a surplus of factories, especially in China, which already produces 80% of solar modules, three‑quarters of wind turbines and 70% of electric‑car batteries. An N‑minus‑one analysis reveals that for every supply chain examined, at least one critical component—such as PV wafers or battery cathode precursors—has less than 25% of non‑Chinese supply, making a single‑month export disruption potentially cost $17 billion in lost EV production. The report cites concrete examples: Chinese firms Jinko Solar, Goldwind and CATL can each satisfy global demand for their respective products, underscoring the depth of geographic concentration. It also notes that while clean‑energy supply chain shocks lack the immediacy of fossil‑fuel crises, they pose significant economic‑security risks, especially for manufacturers lacking alternative sources. Policymakers are urged to address these vulnerabilities by fostering competitive domestic manufacturing, diversifying supplier bases, and pursuing international partnerships. Failure to close competitiveness gaps could undermine energy security, economic stability, and the ability to meet climate targets, making strategic supply‑chain resilience a priority for governments worldwide.

As the IEA’s flagship technology publication, Energy Technology Perspectives (ETP) has been a key source of insights on all matters relating to energy technologies since 2006. The 2026 edition aims to provide a comprehensive update on key energy technology issues.

Against the backdrop of a fast-changing policy and technology landscape, ETP-2026 delivers timely insights into the status and outlook of deployment, manufacturing, project pipelines, investment and trade for a range of energy technologies and materials.

ETP-2026 examines demand-side dynamics for energy technologies — such as deployment trends and policy developments — as well as supply-side factors, including manufacturing capacity and trade flows, underpinned by robust modelling and quantitative analysis. This year’s edition puts a special focus on vulnerabilities in energy technology supply chains and industrial competitiveness, analysing manufacturing cost structures and industrial policy impacts.

At the launch webinar, the report will be presented by Timur Gül, IEA’s Chief Energy Technology Officer, together with Araceli Fernandez Pales, Head of IEA’s Technology Innovation Unit, and Peter Levi, Head of IEA’s Technology Supply Chain Unit.
