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: -Here on Earth, the upper layer of the atmosphere (the ozone layer) filters much of the sun’s ultra-violet (UV) radiation, but passes some onto the surface. The energy that received is then absorbed by the Earth’s air and crust, heating our planet and providing organisms with a source of energy.

Detailed explanation-3: -Nearly all of the earth’s energy comes from the sun. Some of this radiant energy is reflected by water droplets and dust particles in the atmosphere and bounced back into space or scattered throughout the atmosphere; some is absorbed by clouds or ozone.
