For example, when heat from sunlight is absorbed by a substance, the substance gets hot. Also, when radio waves are absorbed (for instance, by a wall), the energy is converted to heat.

Electromagnetic energy refers to energy carried by electromagnetic waves such as light and radio waves, while thermal energy refers to the internal energy present in a system due to the movement of its particles. In other words, electromagnetic energy is carried by electromagnetic fields, while thermal energy is related to the average kinetic energy of particles within a substance.
The process by which thermal energy is transferred through electromagnetic waves is called radiation.
Thermodynamics
By electromagnetic waves.
Sunlight.
When you burn a fuel in air you are converting chemical potential energy into thermal energy. The only energy input needed is to raise the fuel temperature to the ignition point. To obtain electromagnetic energy you have to drive a generator, which requires mechanical energy, so you have to use the thermal energy to drive a heat engine, a gas turbine is a good example.
Non-examples of radiant energy include sound waves, thermal energy transferred through conduction, and mechanical energy generated by moving objects. Only electromagnetic waves, such as light and infrared radiation, are considered forms of radiant energy.
The transfer of thermal energy by electromagnetic waves is called thermal radiation. It does not require a medium and can travel through vacuum. Objects that are hot emit thermal radiation in the form of infrared waves.
