This research is a development that aims to produce a product and determine the validity of flipbook e-modules based on the STEM (Science, Technology, Engineering, and Mathematics) approach to learning the physics of renewable energy materials. The research procedure consists of stages: analysis, design, and development. This research involved two experts, namely, physics material and media, and one learning practitioner. The data collection instrument uses a questionnaire evaluation sheet. The evaluation results obtained a score of 0.87 in the very high validity category from physics subject experts and 0.85 in the very high validity category from media experts. From the results of this evaluation, the flipbook e-module based on the STEM approach to renewable energy topics is very highly valid for use as a physics learning medium.
