This document describes a case study that investigated using videos to teach rural communities in Nigeria about solar cooking. The researcher worked with two non-profits in Nigeria to create locally-made videos in local languages about building and using solar cookers. Nine solar cookers of different designs were built locally and tested. Workshops using the videos helped transfer knowledge about solar cooking. The videos and solar cookers helped build skills and capacity around solar cooking, which has benefits like reducing women's workloads, poverty, and environmental impacts. The study evaluated whether locally-made videos were effective for teaching people new to solar cooking.
