The collaboration between Bruegel and Rhodium Group marks the beginning of a joint effort to compare clean technology deployment and manufacturing trends in Europe and the United States. Both regions have seen a resurgence in industrial policy focused on clean technology supply chains, driven by legislative acts like the Inflation Reduction Act in the US and the Net-Zero Industry Act in the EU. Rhodium Group and Bruegel have developed monitoring tools to track public and private investments in clean technology manufacturing and deployment in their respective regions. The analysis focuses on four key clean technologies: wind, solar, battery electric vehicles, and electrolytic hydrogen. Europe leads in wind, solar, and electric vehicle adoption, while the US has made progress in electric vehicle registrations. Europe overtook the US in electrolyzer deployment for green hydrogen production. In terms of manufacturing, Europe excels in wind and electrolyzer manufacturing, while the US leads in solar and battery cell production. The article discusses the competition between the US and EU for new manufacturing facilities, jobs, and economic development opportunities. It highlights the tensions that have arisen as both governments strive to balance domestic growth, clean energy transition, and energy security. Future briefings in the series will explore how policy differences and economic factors translate into actual projects and groundbreakings, shedding light on the pace of the transition in these major economies. The comparative analysis reveals that the EU has deployed significantly more solar PV and wind capacity than the US, reflecting its leadership in renewable energy deployment. Solar panel manufacturing involves various stages, with the US and EU having notable capacities in module assembly. In wind manufacturing, Europe's expertise is evident in the manufacture of turbines and related components. Overall, the collaborative effort aims to provide insights into the evolving landscape of clean technology deployment and manufacturing, offering a comprehensive view of the progress and challenges in the US and Europe's transition to a more sustainable energy future.
