There is alot waste heat from power consuming companies. This waste heat is added to atmosphere, which is unusable and it adds to global warming. Most of energy sources are consumed by energy sectors. These sectors are energy spending sectors all over world. Consequently, they are answerable for the discharging huge quantity of heat to the atmosphere. This heat is called waste heat which is in form of hot exhaust gases or other hot discharges. Since high prices of sources and wastage of heat made us to think that to recover its energy. It will benefit us from two perspectives in which first one is decreasing carbon amount in discharges and second one is this energy is cheap. Moreover, decreasing the ecological impact. Heat recovery via thermoelectric modules enables us to recover the waste contents with energy. Thermoelectric generator (TEG) is a semiconductor device. TEG module is made which produce electrical voltages whenever thermal gradient is developed on its surfaces. The study of TEG performace is presented in this paper. Voltage, current and power produced are the performance charateristics of TEG. The increase and decrease of temperature difference on both the surfaces of TEG module will show the output results increasing and decreasing respectively .
