About this listen

 The global clean energy industry has seen notable developments in the past 48 hours, marked by fresh policy uncertainty in the US, robust supply chain growth, and record-setting clean power penetration.

In the United States, a significant policy risk emerged as House Republicans proposed an early phaseout of the Inflation Reduction Act’s clean energy tax credits. If implemented, this would disproportionately impact “clean firm” technologies like advanced nuclear and geothermal, which rely heavily on these credits for deployment and innovation. Clean energy buyers and industry advocates, representing major corporations such as Microsoft and Amazon, warned that scaling back these credits could undermine national security and stall technological advances. The Nuclear Energy Institute emphasized that market fundamentals have not shifted, and nuclear is still undervalued for its reliable and secure contributions to a cleaner grid. In tandem, any downsizing at the Department of Energy, particularly in programs supporting clean energy demonstrations and loan guarantees, could further set back emerging technologies and shake investor confidence[1].

Globally, renewables now supply over 40 percent of total electricity generation—a new record. Solar power continues to lead this expansion, doubling its output in the last three years and accounting for much of the 858 terawatt-hour increase in renewable generation in 2024. However, surging electricity demand driven by heatwaves caused a minor increase in fossil power output, nudging power sector emissions to an all-time high. This indicates that while renewable capacity is expanding rapidly, matching demand spikes remains a challenge[2].

In supply chain news, US clean energy manufacturing—especially in batteries, solar, and zero-emission vehicles—has seen strong investment and capacity growth since the IRA passed. Domestic battery manufacturing capacity now exceeds demand and is projected to keep pace with, or surpass, grid and vehicle storage needs through the next decade. Solar module production also meets current deployment, and ZEV manufacturing could soon supply the majority of domestic demand. By contrast, wind manufacturing lags due to weaker investment and fewer new projects, highlighting persistent sectoral imbalances[5].

Overall, while clean energy’s global share and manufacturing capacity are at historic highs, US policy uncertainty, supply chain gaps in wind, and rising short-term emissions create a complex landscape. Industry leaders are advocating strongly for stable policy support and diversifying their supply chains to navigate these ongoing challenges[1][2][5].
