Abstract Inherent scarcity of thermal sources with a time varying temperature profile is the reason why the Thermo electric-based energy harvesting is not as prominent as its counter-part, thermoelectric generators, in the thermal energy harvesting domain. A practical solution for generating thermal oscillations required for sustainable Thermo electric-based energy harvesting from the solar and wind energy is presented. The main focus of the work is to modulate the concentrated solar radiation using a vertical axis wind turbine for producing higher rate of change of temperature on the Thermo electric material. Piezoelectricity should not be confused with thermoelectricity    in a typical demonstration of pyroelectricity, the whole crystal is changed from one Temperature to another and the result is a temporary voltage across the crystal. in a typical demonstration of thermoelectricity, one part of the device is kept at one temperature and the other part at a different temperature, and the result is a permanent voltage across the device as long as there is a temperature difference.
