Global investment in clean energy technologies reached a record $1.3 trillion in 2025, exceeding fossil fuel investment for the second year running and marking a decisive shift in the allocation of global capital toward decarbonization, according to the International Energy Agency’s annual World Energy Investment report.
The Numbers
Solar accounted for the single largest slice of clean energy investment at $380 billion, followed by wind at $270 billion, electric vehicles and charging infrastructure at $250 billion, and grid modernization at $180 billion. The remainder was split among energy storage, hydrogen, and nuclear.
The Decline of Fossil Fuels
Investment in oil, gas, and coal declined 8% year-over-year to approximately $700 billion — the third consecutive annual decline. The IEA noted that much of this remaining fossil fuel investment is concentrated in a small number of national oil companies and developing economies where energy transition financing remains limited.
Geographic Distribution
China remained the single largest investor in clean energy, accounting for nearly 40% of global totals. The European Union and the United States each represented approximately 20%, with the remainder distributed across Southeast Asia, the Middle East, and Latin America.
The Financing Gap
Despite record investment levels, the IEA estimates that meeting global climate targets requires clean energy investment to reach $4.5 trillion annually by 2030. Closing the financing gap will require a fundamental restructuring of how development finance institutions, sovereign wealth funds, and private capital markets operate in emerging economies.
