The Sun is the major source of light for the earth. The sun is a massive ball of fire, at the centre of which nuclear fusion produces massive energy. This energy comes out as heat and light.
Symbols representing physical quantities, units, mathematical operations and relationships, astronomical bodies, constellations, and the Greek alphabet.
The source of solar power is energy carried by the electromagnetic waves radiated by the Sun. Most of this energy is carried by visible light and infrared (heat) radiation.

Energy (from Ancient Greek ἐνέργεια (enérgeia) 'activity') is the quantitative property that is transferred to a body or to a physical system, recognizable in the performance of work and in the form of heat and light.
In simple words, it tells us how some type of energy, for example, heat moves from one body to another and converts into another form of energy such as kinetic energy. In thermodynamics, we use symbols to represent heat, work, energy and their relationship.
The study of heat and temperature is part of an area of physics known as thermodynamics. The laws of thermodynamics govern the flow of energy throughout the universe. They are studied in all areas of science and engineering, from chemistry to biology to environmental science.
