Planned or under-construction solar and wind projects slowed last year, analysis showed Tuesday, casting doubts on whether countries will hit a goal of tripling renewable capacity by decade-end.
Dozens of nations agreed in 2023 to triple renewable energy capacity by 2030 as part of efforts to limit global warming.
But announcements and construction starts of new wind and solar projects grew 11 percent in 2025, down from 22 percent in the previous year, as wind development projects faced hurdles, Global Energy Monitor (GEM) said.
"Wind developers experienced political barriers and a streak of failed wind power auctions in wealthy nations," GEM research analyst Diren Kocakusak said.
U.S. President Donald Trump has blocked wind projects, and made no secret of his antipathy towards renewables, though the global slump was not attributable to any one country, Kocakusak said.
GEM's research also found that just a small fraction of wind and solar growth came from rich G7 countries, with the "center of gravity" now shifting "decisively toward emerging and developing economies."
As has been the case for years, China is expanding renewable capacity on a scale unmatched elsewhere.
It accounted for around a third of global capacity growth in 2025, 1.5 terawatts, more than growth in the next six countries combined.
But that was not enough to set the world on track to meet the 2030 goal.
Even if all the projects currently announced and under-construction proceed, the world would still fall short.
GEM's research has found almost 40 percent of planned projects begin operations after their announced start date, or are put on hold or scrapped.
