Explanation:
Detailed explanation-1: -Solar energy is created by nuclear fusion that takes place in the sun. Fusion occurs when protons of hydrogen atoms violently collide in the sun’s core and fuse to create a helium atom. This process, known as a PP (proton-proton) chain reaction, emits an enormous amount of energy.
Detailed explanation-2: -Amount of energy released in one fusion reaction = 4.3 x 10-12Joules/reac.
