Thermoelectric power generation technology has been expected to play an important role in the enhancement of our social safety, energy security, environmental conservation and stimulus to industry in the future. This paper introduces the present status and future prospects on the Research and Development of the thermoelectric power generation technology. After the brief explanation of the basic principle and the relationship between energy conversion efficiency and thermoelectric performance parameters, the enhancement effect of thermoelectric performance by means of thermoelectric nanostructured-technology is introduced as one of innovative approaches. The thermoelectric power generation systems can be applied to the waste heat recovery such as automobile, industrial furnace, incinerator and so on, to the renewable energy sources such as solar energy and hot springs, and to the energy harvesting from environmental heat, human body, device exhaust heat and so on. Finally, the problems for the realization of thermoelectric power generation systems to the society are discussed.
