This research aims to test the efficiency of wind, solar and water-powered renewable energy prototypes and examine experts’ and practitioners’ responses to the prototype for STEM education purposes. There are a total of three experiments in this research; namely, evaluating the amount of electrical energy generated from changing propeller angles in wind turbines, the effect of the cross-sectional area and slope on electrical energy in solar panels, and the generation of electricity from water using proton exchange membranes in miniature cars. Ten experts and practitioners assessed the three prototypes. The experiments demonstrated their effectiveness in teaching renewable energy principles, with significant findings on the blade’s type and angle for the wind energy STEM kit (WESK), and consistent hydropower output for the multi energy car STEM kit (MECSK). Expert evaluations confirmed the prototypes’ feasibility, highlighting their user-friendliness, accuracy and motivational impact on students. These findings imply that such prototypes can significantly enhance STEM education and support sustainable development goals by promoting knowledge and interest in sustainable energy technologies. © (2024), (World Institute for Engineering and Technology Education).
