A system and method for generating energy with human powered devices and providing environmental feedback to users is disclosed which motivates individuals to use the equipment for the purpose of improving the environment. Fitness equipment is fitted with energy conversion devices such as electric generators to convert human powered energy to electrical energy. Energy that is generated by the user is converted to a quantitative or qualitative environmental feedback parameter. The environmental feedback parameter is indicative of the user's positive effect on the environment as a function of the energy generated by their use of the fitness equipment. The environmental feedback parameter is displayed to the users during their use of the equipment, and may be stored as a log of individual session use, or cumulative total use, for later examination by the users or for group use.
