Energy innovation enters security-focused phase as batteries dominate patent landscape
…emerging energy technologies tracked by the IEA.At the same time, the policy context is shifting. In a survey of experts and practitioners, energy security emerged as the leading driver of innovation in 2025, ahead of affordability and emissions reduction. New initiatives such as the US Genesis Mission and the EU Competitiveness Fund reflect growing emphasis on strengthening domestic technological capabilities and securing critical supply chains.“Energy innovation has become a strategic priority for governments around the world,” said IEA Executive Director Fatih Birol. “With energy security and industrial competitiveness at the top of the agenda, countries that sustain investment…

Strait of Hormuz crisis reinforces need for Southeast Asia to tackle major energy vulnerabilities
…trajectory that the region was on prior to the current energy crisis triggered by the conflict in the Middle East – and considers the potential implications of the crisis for policy priorities and investment strategies.The report highlights the extent to which Southeast Asia is exposed to the current crisis. The Middle East accounts for 60% of the region’s crude oil imports, and almost half of the oil products that are refined or consumed in Southeast Asia come from Middle East crude oil. As a result, the virtual shutdown of energy shipments through the Strait of Hormuz has had major…

Economic growth
…1 spent on energy efficiency programmes would generate between USD 4 and USD 7 in GDP between 2017 and 2030. In the United States, a study funded by the Department of Energy estimated that doubling energy productivity could result in a net GDP increase of USD 922 billion between 2015 and 2030. Increase in labour productivityAn analysis of over 15 000 European firms found that those investing in energy efficiency can see increases in labour productivity – the amount of economic activity per unit of labour – between 1.4% and 3.6% compared with firms with no investment in energy efficiency.Improvement…

Scaling Up Transition Finance What is transition finance?
…Over half of those investments would be in EMDE, spanning energy efficiency, selected low-emissions technology across different end-use sectors, and some investments in natural gas infrastructure, gas-fired power, critical minerals, and other areas.The core of transition finance lies in its dynamic nature, shaped by the diversity of national energy pathways, the fact that types of investments needed evolve over time and the necessity of taking a view on the likely length of the transformation. However, this nature makes it difficult to define a uniform global framework, since investments essential in one region may be unnecessary in…

China’s Official Energy Finance in Emerging and Developing Economies Case 2. Southern power grid’s acquisition of Enel Peru distribution assets
Project overview and impact Latin America’s power systems face a growing need to modernise their electricity networks as clean energy deployment accelerates. While the region has seen a 25% increase in clean energy investment since 2015, grid spending has not kept pace, with less than USD 0.5 invested in networks and storage for every dollar spent on new generation. Strengthening distribution systems, especially in rapidly expanding urban areas, is essential to integrate more renewables. Peru is no exception. Although its electricity demand has grown steadily, network modernisation has lagged behind regional leaders, and the expansion of renewable capacity…
