The IEA's high-level distinguished speaker series, big IdEAs, brings top thinkers, decision makers and global leaders to give talks that are idea-focused on a wide range of subjects that are timely and relevant but not always directly related to energy. The aim is to foster learning and inspiration – and provoke discussions that matter. Please join IEA member country ambassadors, IEA experts and viewers worldwide for these discussions, as they are live-streamed from the IEA website.
