Yes, this is mostly true. It starts to become untrue near silicon.
Electric current
The energy carried by an electric current depends on a conductor in order to flow. an Insulator disrupts the flow
Aluminum is a conductor of thermal energy and electrical energy.
a metal
Something that conducts thermal energy well is a thermal...conductor. If it does not conduct well it is called an insulator.
Then an 'electrical current' is said to be present in the conductor.
Thermal energy exists in materials raised to a high temperature, because they can then transfer this energy to materials at lower temperatures. For example , heating radiators transfer energy to the building they are in. Electric energy is basically the movement of free electrons in a conductor, which can then do work such as turn an electric motor, or indeed produce thermal energy in a heating element,
Before you can understand how electrical energy is supplied by your electric company, you need to know how it is produced. A magnet and a conductor, such as a wire, can be used to induce a current in the conductor. The key is motion. An electric current is induced in a conductor when the conductor moves through a magnetic field. Generating an electric current from the motion of a conductor through a magnetic field is called electromagnetic induction. Current that is generated in this way is called induced current. To induce a current in a conductor, either the conductor can move through the magnetic field or the magnet itself can move.
Assuming you mean, "What are examples of the CONVERSION of electrical energy to thermal energy?", then we have electric fires (radiant bar fires, electrical radiators, fan heaters), electric kettle. In fact any electrical device that gives off heat - which is nearly all of them. What happens is that the electrons that constitute the electric current, when they flow through a material that is not a good conductor, get jostled about, bang into each other, and generally cause the poor conductor to shake around (on the molecular scale). This shaking is basically what heat energy is, and is then passed on to neighbouring substances or radiated away.
