We are all set to step into the final quarter of 2025 tomorrow, and the clean energy industry remains in the spotlight, rallying impressively throughout the year. This momentum is backed by record global investment, which hit a record $386 billion (up 10% year over year as reported by BloombergNEF) in the first half of 2025 alone, amid relentless demand from new electricity loads like data centers and cleantech manufacturing.

The S&P Global Clean Energy Select Index reflects this strength, having posted a solid 37.4% return year to date, driving clean energy ETFs like the Invesco WilderHill Clean Energy ETF ((PBW Quick QuotePBW - Free Report) ) and the iShares Global Clean Energy ETF ((ICLN Quick QuoteICLN - Free Report) ) to soar noticeably, as well.

Factors Reshaping the Global Clean Energy Industry

The global clean energy industry has been rallying high lately, driven by a confluence of powerful factors. Key tailwinds include favorable government policies worldwide, the declining cost of renewable technologies, increasing corporate investments, and rapid technological innovation that lowers installation costs and improves efficiency. In addition, soaring power demand from the exponential growth of power-hungry data centers and the rapid electrification of the transportation sector certainly remained the two major growth drivers for the industry.

Consequently, the overall outlook for this industry remains highly optimistic in Q4. However, no one can deny the fact that the significant domestic headwinds faced by the U.S. clean energy market remain a challenge for this industry. Recent U.S. administrative policy changes — such as the rollback of certain tax credits under the "One Big Beautiful Bill Act (OBBBA)" and import tariff uncertainty — have created a volatile policy landscape. This uncertainty resulted in a 36% drop in U.S. renewable energy investment in the first half of 2025 compared to the second half of 2024, a softness that may continue into Q4.

Despite the U.S. slowdown, the global clean energy boom continues, with other nations driving growth. Notably, the European Union saw a 63% jump in investment in the first half of 2025, backed by government support and a push for energy independence. On the other hand, China remains the largest market, accounting for 44% of global new investment. In addition, smaller markets in regions like Southeast Asia and Latin America gained their largest share of regional investment to date. This broad global commitment suggests that the global clean energy industry’s overall growth trajectory will remain robust as we enter the October-December quarter.
