      If you have a lot of heat, then you can do what power plants do….you can use the heat to generate steam, and use the steam to spin a turbine. The turbine can drive a generator, which produces electricity.

      Yes, you can convert heat energy to electric energy through a thermoelectric generator. This is a solid-state device that converts heat flux into electric energy through the Seebeck effect

      Yes you can. The geothermal plant in Olkaria is an example of this. The thermal energy(heat) is used to generate electricity which is later distributed to us by Kenya Power

      Yes it is possible. Thermo-electric gadgets can use thermal differences to convert temperature gradient directly into electrical energy and generate electricity.
