According to Wikipedia:

"Thermoelectric cooling uses the Peltier effect to create a heat flux between the junction of two different types of materials. A Peltier cooler, heater, or thermoelectric heat pump is a solid-state active heat pump which transfers heat from one side of the device to the other side against the temperature gradient (from cold to hot), with consumption of electrical energy. Such an instrument is also called a Peltier device, Peltier diode, cooling diode, Peltier heat pump, solid state refrigerator, or thermoelectric cooler (TEC). Because heating can be achieved more easily and economically by many other methods, Peltier devices are mostly used for cooling. However, when a single device is to be used for both heating and cooling, a Peltier device may be desirable. Simply connecting it to a DC voltage will cause one side to cool, while the other side warms. The effectiveness of the pump at moving the heat away from the cold side is dependent upon the amount of current provided and how well the heat can be removed from the hot side."

A peltier cooler is not a thermopile nor a thermocouple and it does not rely on the seebeck effect.

Thermo means heat, so a thermoelectric power plant produces electricity by burning something. This is usually one of the fossil fuels (coal, oil and natural gas), but it can also be biomass, biogas, bio vegetation, and even garbage.

The burning usually turns water into steam which powers the electricity generators.

How is a refrigerator an example of a heat mover?

Normally, heat moves from a higher temperature to a lower temperature. Devices that use work to move heat are called heat movers. A refrigerator is an example of a heat mover because it takes the heat from inside of the refrigerator and moves it to the outside. The 2nd law of thermodynamics allows this to occur if work is done in the process. A refrigerator does work as it moves the heat from inside the refrigerator to the warmer room.
