The renewed interest is being driven by clean energy and power storage deals, and comes despite the Trump administration's backpedaling on climate policy.

Global investment in green technology for the first three quarters of the year has already surpassed all of 2024. The fortunes of the sector have been in decline for three years, but explosive energy demand fueled by data centers has sparked a reversal.

Private and public investors worldwide channeled as much as $56 billion into green businesses ranging from clean energy to storage and electric vehicles during the nine months ending in September, according to a new BloombergNEF report. By contrast, the climate tech industry snagged less than $51 billion in 2024.

The renewed interest is being driven by clean energy and power storage deals, and comes despite the Trump administration's backpedaling on climate policy. Major deals include Chinese battery giant Contemporary Amperex Technology Co. Ltd., which raised about $5 billion from its Hong Kong initial public offering in May. The country’s electric car maker BYD Co. also raised $5.2 billion in share sales in March, while Spanish renewable energy giant Iberdrola SA sold $5.9 billion worth of shares in July.

Nuclear energy drew a fifth of all climate venture capital funding, in a large part "driven by the AI hype," said Musfika Mishi, a BNEF analyst. That includes a $863 million raise by Commonwealth Fusion, which drew funding from Nvidia Corp.’s venture arm.
