Global energy transition investment hits a record: electric transportation leads with $893 billion, as the EV industry chain enters a new growth cycle

Introduction

In 2025, global energy transition investment surpassed $2.3 trillion for the first time, up 8% year-on-year, reaching a record high. According to BloombergNEF's latest Energy Transition Investment Trends report, electric transport became the largest investment sector, attracting $893 billion over the year, far exceeding renewable energy and power grids. This figure not only reflects the rapid expansion of the electric vehicle (EV) market, but also highlights that the battery supply chain, charging infrastructure, and smart mobility ecosystem are becoming the core engines of the global energy transition. For the global EV industry, this marks a turning point from "policy-driven" to "capital-industry resonance."

Industry Background

Over the past decade, global energy transition investment was primarily driven by renewable energy power generation, but the 2025 data reveals a structural shift: electric transport investment has surpassed renewable energy to become the largest investment area in the energy transition. The report shows that renewable energy investment in 2025 was $690 billion, down 9.5% year-on-year, mainly due to policy adjustments in China's electricity market; meanwhile, electric transport investment continued to climb from its 2024 level, reflecting the capital attractiveness of electric vehicles, charging networks, battery manufacturing, and other segments.

At the same time, clean energy supply investment exceeded fossil fuel supply investment for the second consecutive year, with the gap widening from $85 billion in 2024 to $102 billion. Fossil fuel supply investment fell for the first time since 2020, decreasing by $9 billion, with notable declines in upstream oil and gas and fossil power generation investment. This contrast indicates that capital is accelerating its shift from traditional energy to clean energy, particularly the industrial chain related to electric transport.

Key Developments

In 2025, electric transport investment reached $893 billion, covering multiple key segments:

• Electric vehicles: Global EV sales continued to grow, and electrification penetration in major markets kept rising, driving expansion in investment in vehicle manufacturing and parts supply.
• Battery supply chain: Battery manufacturing and materials investment became the main driver of supply chain investment growth. In 2025, clean energy supply chain investment reached $127 billion, up 6% year-on-year, with significant increases in investment in battery factories and battery metal mining projects.
• Charging infrastructure: As a key support for EV adoption, charging network construction attracted substantial capital, with new models such as supercharging stations, fast-charging technology, and V2G (vehicle-to-grid) constantly emerging.
• Grid upgrades: Grid investment reached $483 billion, becoming the third-largest investment area after electric transport and renewable energy. Modern grids are the foundation for supporting large-scale EV integration and renewable energy consumption.In addition, the report also pointed out that data center investment is expected to reach approximately $500 billion in 2025, surpassing solar investment. The explosive growth of artificial intelligence and high-performance computing has created new electricity demand, and technology companies are securing power supply through long-term renewable energy contracts and energy storage projects, opening up new growth space for clean energy and grid investment.

Industry Impact

Electric mobility is leading energy transition investment and has had a profound impact on the global EV industry chain.

• Battery technology: Investment in battery manufacturing and materials is growing, accelerating the commercialization of next-generation technologies such as solid-state batteries and sodium-ion batteries. At the same time, battery recycling and critical mineral processing are attracting more capital, with a clear trend toward supply chain localization. China still dominates supply chain investment, but the investment shares of the United States, the European Union, and India are rising, and the global battery supply chain is expected to form a multipolar landscape.
• Charging network: Large-scale investment is shifting charging infrastructure from the bottleneck of an insufficient vehicle-to-charger ratio toward a moderately advanced approach. Advances in fast-charging and wireless charging technologies have improved user experience, while V2G and smart charging turn electric vehicles into mobile energy storage units, creating synergy with the grid.
• Smart mobility: Investment in electric mobility is driving the development of autonomous driving and connected vehicles. The report shows that equity financing for climate tech companies reached $77.3 billion, up 53% year-on-year, with low-carbon transportation and energy storage as the main directions. The public equity market is recovering, with large deals mainly coming from Asia, while early-stage venture capital declined for the third consecutive year, intensifying industry consolidation.
• Energy enterprise transformation: Traditional energy companies are under pressure, with fossil fuel investment declining. At the same time, many oil and power companies are shifting capital toward EV charging services, battery energy storage, and renewable power generation to address the long-term trend of energy transition.

Challenges and Risks

• Despite record investment levels, the global energy transition still faces multiple challenges.- Decline in renewable energy investment: Renewable energy investment fell by 9.5% year-on-year in 2025, mainly due to policy uncertainty in China's electricity market. As the world's largest market, China's policy adjustments could slow the global growth rate of clean energy installations, thereby affecting the supply of green electricity for EVs.
• Overcapacity in the supply chain: Investment in clean energy supply chains continues to grow, but all segments face overcapacity pressure. Declining product prices in areas such as batteries and photovoltaics, while beneficial to the end market, compress the profit margins of manufacturers and may dampen future investment.
• Slowing investment growth: The growth rate of energy transition investment fell from 27% in 2021 to 8% in 2025, indicating weakening marginal growth momentum. Policy uncertainty, trade barriers, and rising financing costs could further weigh on investment.
• Technology pathway risks: Investment in hydrogen and nuclear energy remains relatively small ($7.3 billion and $36 billion, respectively). Industrial decarbonization and electrification of heavy-duty transport still require breakthrough technologies. Long-term supply of battery metals may face mismatches, requiring sustained investment to safeguard the security of the industrial chain.
