The EuropeanCommission alsoparticipates in thework of the IEA Source: IEA.International Energy AgencyWebsite: www.iea.org Abstract Energy security in the Age of Electricity is inextricably linked to securing the supplychains for clean energy technologies and the equipment and materials used tomanufacture them. As countries continue to pursue energy transitions and to directinvestments to these technologies, guided by industrial strategies, a detailedunderstanding of their supply chains has an essential role to play. The availabilityofgood-quality, timely data is crucial to gaining this understanding and toidentifying and addressing supply chain vulnerabilities. This report is provided as an input to the discussions taking place as part of theGlobal Clean Power Alliance Supply Chains Mission – an initiative established bytheGovernment of the United Kingdom to advance practical solutions tostrengthen clean power supply chains. This report addresses the data componentof this initiative and explores the challenges – and potential solutions – to thepaucity of granular and timely data associated with clean energy technologysupply chains.
