Hope the following helps.
Thermal energy has no generally agreed definition and the term will not usually be found in most dictionaries of physics or science. In everyday usage, thermal energy may be regarded either as 1. a synonym for thermodynamic energy (itself a synonym for internal energy) or as 2. a synonym for heat.
1. Seen as the internal energy of a system, there are two components to thermal energy. One component is the internal potential energy of the system - the energy the system contains at any moment due to the relative placement within the system of all its constituent parts. The second component is the internal kinetic energy of the system - the energy the system contains at any moment due to the relative motion within the system of all its constituent parts
Wherever you look, you can see examples of energy transfers. When you turn on a light, you see result of energy being transferred from the sun to the plants to the coal to electricity and finally to light you see. During each of these transfers, energy changes form. There are two main forms of energy, kinetic energy (motion) and potential energy (position). To further classify energy, these forms are sometimes further described as thermal (heat), elastic, electromagnetic (light, electrical, magnetic), gravitational, chemical (food), and nuclear energy. See the What is Energy: Two Main Forms of Energy for more information on kinetic and potential energy.
