Technology manufacturing plays a pivotal role in the energy transition required to meet climate, energy security and economic development goals. Deploying clean energy technologies at the pace required to put the world on a trajectory consistent with net zero emissions by mid-century will demand rapid expansion in manufacturing capacity, underpinned by secure, resilient and sustainable supply chains for their components and materials.

The State of Clean Technology Manufacturing: Energy Technology Perspectives Special Briefing provides an update on recent progress in clean energy technology manufacturing in key regions. It focuses on five technologies – solar PV, wind, batteries, electrolysers and heat pumps – that will be critical to the energy transition. Manufacturing capacity for these technologies is expanding rapidly, driven by supportive policies, ambitious corporate strategies and consumer demand. The aim is to keep decision makers informed of investment trends and the impact that recent industrial strategies are having in these highly dynamic sectors.

This special briefing was produced to support deliberations at the 2023 G7 Leaders’ Summit in Hiroshima, Japan, from 19-21 May 2023. It builds on analysis in the latest edition of the IEA’s flagship technology publication, Energy Technology Perspectives 2023 (ETP-2023), published in January 2023, to take into account the latest announced expansions in manufacturing capacity.
