Clean energy technology manufacturing is expanding rapidly, driven by supportive policies, ambitious corporate strategies and consumer demand. The global energy crisis has instilled  further impetus to develop manufacturing capacity that can strengthen energy security and  diversify the supply chain. This Energy Technology Perspectives (ETP) Special Briefing is  designed to provide policy makers with strategic insights in this area, focusing on five critical  technologies: solar photovoltaic (PV), wind, batteries, electrolysers and heat pumps. Clean energy technology manufacturing is expanding rapidly, driven by supportive policies, ambitious corporate strategies and consumer demand.
