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.

what about heat energy from jiko can it be converted to electric energy???
Koko commented on :
Charcoal has carbon that is derived from plants and therefore can be a source of energy. Here are steps of converting coal to electric energy, so l assume that the same can be applied to charcoal.
1) A machine called a pulverizer grinds the coal into a fine powder.
2)The coal powder mixes with hot air, which helps the coal burn more efficiently, and the mixture moves to the furnace.
3)The burning coal heats water in a boiler, creating steam.
4)Steam released from the boiler powers an engine called a turbine, transforming heat energy from burning coal into mechanical energy that spins the turbine engine.
5)The spinning turbine is used to power a generator, a machine that turns mechanical energy into electric energy. This happens when magnets inside a copper coil in the generator spin.
6)A condenser cools the steam moving through the turbine. As the steam is condensed, it turns back into the water.
7)The water returns to the boiler, and the cycle begins again.
