Thermoelectric generators act as renewable energy sources

Abstract

The thermoelectric generator (TEG) is a solid-state energy converting device that converts heat directly into electrical energy. TEGs are silent, scalable, and reliable, as they have no moving parts. The consciousness of surroundings pollution correlated with global warming has resulted in an upsurge of technological research to develop eco-friendly energy resources. TEG employs waste heat to generate power and thus can be the termed eco-friendly energy source. In the economic aspect, waste heat is a free source for generating electrical energy. It can handle the heat generated by the human body, computer chips, automobile engines, and industrial utilities. TEG used as a renewable energy source has been presented in this review article. It would help in the development of establishing a low-power solution and high-performance system. The present status, prospect, and update information about the TEG used as a renewable energy source has been discussed in detail. This review article also provides a recommendation, which system would be suitable for electrical energy generation by TEG through renewable energy resources.
