The sunlight that reaches earth is generated by a transformation of nuclear energy. Radiant energy is a from of energy that reaches the earth from nuclear reactions in the core of the sun.

In this process, light nuclei combines to form larger ones through the process of nuclear fusion.
This process does not conserve energy and mass is converted to energy.
The nuclear reaction produces huge energy that goes into the solar system space and lights it up.
Therefore, it is a transformation of nuclear energy into radiant energy.
The radiant energy is made up of electromagnetic radiations.
