This report systematically identifies key challenges in HE interventions and develops an evidence-based process for capturing project learnings. This was achieved through a mixed-methods approach combining desk research, stakeholder interviews, and case study analysis. Findings from the research were used to propose an initial design for the Humanitarian Energy Learnings Platform (HELP), intended as an inter-donor system for capturing learnings. The case studies were used to test the forms and processes that constitute HELP.
