In this paper, the situation of energy efficiency standards and MEPS (Minimum Energy Performance Standard) for motors and diffusion states are analyzed. For this purpose, a new methodology is used, which was proposed in the existing study, using diffusion models and learning curves. The existing diffusion models could not explain affects from new appliances' penetration during the diffusion. But a mixed diffusion model with learning curves or learning ratio is studied to explain this penetration.
