6 JUN 2025 · In the past 48 hours, the clean energy industry has faced a complex mix of progress and disruption. Globally, clean energy investment continues to surge, with the International Energy Agency estimating that spending on clean energy and grids will reach 2.2 trillion US dollars in 2025, which is double the expected investment in fossil fuels for the year. More than 90 percent of new energy capacity built worldwide last year was clean energy, driven by falling costs and strong decarbonization policies. However, despite these advances, power sector emissions rose by 1.7 percent last year due to unprecedented demand.
In the United States, a major shift is underway: for the first time, fossil fuels accounted for less than half of electricity production as of March, with renewables and nuclear meeting 51 percent of demand. Still, the industry is encountering significant headwinds. A newly proposed House bill threatens nearly 500 gigawatts of planned solar and storage projects, putting at risk a quarter of future US clean energy growth. These projects, particularly in Texas and California, face potential delays or cancellations due to permitting bottlenecks, supply chain issues, and recent tariffs. Developers now face compressed timeframes to begin and complete projects, with storage projects facing the highest risk.
Beyond legislation, regulatory changes are also posing challenges. The recent rescinding of 3.7 billion dollars in US federal funding for industrial decarbonization has been labeled a major blow to clean heat technologies. This move could slow efforts to replace fossil-fueled boilers with electric alternatives, impacting clean industry transition efforts.
Supply chain disruptions remain a persistent obstacle. According to recent reporting, American clean power project delays linked to supply chain and permitting issues now average 16 months, and risks may rise with new tariffs.
Meanwhile, some regions are struggling with surging clean energy production. In California, record solar and wind generation is sometimes wasted as grid infrastructure cannot keep pace, forcing curtailments of surplus power.
Despite these setbacks, industry leaders are responding by forging new partnerships and leveraging technology. For example, PJM, the largest US grid operator, has announced a partnership with Google to use artificial intelligence for more efficient grid management, aiming to ease bottlenecks and advance renewable integration.
Overall, while clean energy investment and adoption are breaking new records, the industry faces mounting political, regulatory, and infrastructure challenges that threaten to slow its momentum. Compared to prior periods, the current environment is marked by both unprecedented opportunity and significant risk, requiring agile responses from leaders and policymakers.
