In a first-of-its-kind analysis, Advancing Clean Technology Manufacturing reports that global investment in manufacturing five key clean energy technologies (solar PV, wind, batteries, electrolysers, and heat pumps) reached $200 billion in 2023. This marked a growth of over 70% from 2022 and contributed about 4% to global GDP growth.
The report reveals that numerous projects currently in development will soon become operational.
Approximately 40% of investments in clean energy manufacturing in 2023 were allocated to facilities scheduled to start operations in 2024. Specifically for batteries, this percentage increases to 70%.

“Record output from solar PV and battery plants is propelling clean energy transitions – and the strong investment pipeline in new facilities and factory expansions is set to add further momentum in the years ahead,” said IEA Executive Director Fatih Birol.
“While greater investment is still needed for some technologies – and clean energy manufacturing could be spread more widely around the globe – the direction of travel is clear. Policymakers have a huge opportunity to design industrial strategies with clean energy transitions at their core,” Birol added.

Advancing Clean Technology Manufacturing integrates insights from a key dialogue on diversifying clean technology manufacturing hosted at the IEA’s headquarters in Paris in November 2023.
It builds on analysis from the latest edition of the IEA’s flagship technology publication, Energy Technology Perspectives, and two special briefings on clean technology manufacturing published last year.
