Detailed explanation-1: -Sun is the primary source of energy for Earth.

Detailed explanation-2: -The sun generates energy from a process called nuclear fusion. During nuclear fusion, the high pressure and temperature in the sun’s core cause nuclei to separate from their electrons. Hydrogen nuclei fuse to form one helium atom. During the fusion process, radiant energy is released.

Detailed explanation-3: -The primary energy source on the earth’s surface is sunlight, which can be harnessed in several ways [54].

Detailed explanation-4: -The main source of almost all the energy on the earth is the sun. In fact, for all the planets, the sun is the main source of heat and light.
