The document discusses opportunities for thermoelectric generation (TEG) technology in various applications including waste heat recycling, geothermal electricity generation, and solar PV. It analyzes the potential TEG markets in these sectors and estimates annual TEG quantities of 600 million units for waste heat incinerators, 120 million for geothermal power plants, and 735 million for solar PV, totaling over 1.4 billion units per year. System integrators in each sector are also identified.
