In the last few years, there has been intensive research in the field of human motion and environment energy harvesting. That kind of energy harvesting used for power supply self-regulation in eWALL system (e WALL for Active Long Living) would contribute to increased energy efficiency of the system. The paper will represent possible methods and ways of energy harvesting in eWALL system. Statistical evaluation of the harvested energy will be given. The paper will also consider other, possible undeveloped ways of energy harvesting in terms of the practical implementation of the system. These methods and statistical estimates may relate to eWALL system, but also to other systems such as e.g. smart homes. Energy accumulation can be achieved from user motion, differences in ambient temperature, vibrations, radio frequency radiation and other technologies that are available to eWALL users.
