1. Types of electric heating

1.1 Origin of electricity

Electricity is produced by transforming mechanical energy using generators, which are driven by various means:

• steam turbines powered by thermal energy from coal or liquid fuels;

• hydraulic turbines using the energy of waterfalls ;

• steam turbines using the heat released by atomic decay in nuclear power plants.

Only the last two forms of production are economically viable, as the first involves a double transformation of the thermal energy of the fuels, making it more expensive.

Electricity is ideal for the user, as it requires minimal installation and no operating labor, and offers...
