The Transforming Humanitarian Energy Access (THEA) programme aims to ensure that no one is left behind in displacement settings in the transition to sustainable energy solutions. THEA is led by the United Nations Institute for Training and Research (UNITAR) and is supported by the Transforming Energy Access (TEA) platform. It seeks to support inclusive and transformative investments in sustainable energy throughout the humanitarian sector and to mainstream investments in humanitarian contexts through collaborations with TEA partners. Furthermore, THEA aims to enable the UN system and humanitarian partners to deliver sustainable energy access in displacement settings using more inclusive practices.
