BloombergNEF’s annual Energy Transition Investment Trends report shows that global energy transition investment continued to increase in 2025, although growth momentum weakened compared with previous years. The findings indicate that clean energy sectors remain dominant in overall capital allocation, while structural and policy factors are reshaping investment patterns across regions and technologies.
Global investment reached $2.3 trillion in 2025, an increase of 8% compared with the previous year. Electrified transport accounted for $893 billion, renewable energy $690 billion and power grids $483 billion. Renewable energy investment declined by 9.5% year on year, largely due to regulatory changes in China that introduced uncertainty in the world’s largest market. All other sectors tracked by BloombergNEF recorded higher investment, except hydrogen at $7.3 billion and nuclear at $36 billion.
Clean energy supply investment exceeded fossil fuel supply investment for the second consecutive year, with the gap widening to $102 billion from $85 billion in 2024. Clean energy investment continued to rise, while fossil fuel supply investment declined by $9 billion, driven mainly by lower spending on upstream oil and gas and fossil power generation. Despite record levels of energy transition investment, growth has slowed steadily from 27% in 2021 to 8% in 2025.
Asia Pacific remained the largest investment region, accounting for 47% of the global total. China remained the largest national market with $800 billion of investment, but recorded its first decline in renewable energy funding since 2013. India’s investment increased to $68 billion, while the European Union recorded $455 billion and the USA $378 billion, despite policy headwinds.
Clean energy supply chain investment grew to $127 billion in 2025, supported by new manufacturing facilities and battery materials projects. Growth was driven mainly by battery manufacturing and materials, although persistent overcapacity continues to exert downward pressure on clean technology prices. China maintained a dominant share of global supply chain investment, a trend BloombergNEF expects to continue in the near term.
The report concludes that mature segments of the energy transition, including renewables, energy storage, electric vehicles and power grids, continue to attract the majority of capital due to lower risk profiles and increasingly established business models.
