Sun Energy , one of the most popular renewable sources of energy and widely used energy is obtained from the Sun which is present at the centre of the solar system. Since all the orbits of the planets are located around this sun, the system is named as Solar system. Early centuries scientists predicted that earth is at the centre but later on, the improvements in technology helped people to find out what is the truth. Though this solar energy is used widely, there exits a question, “ How is the sun producing this much energy and from where?” The answer lies with Sun itself. Isn’t it amazing? a particle is producing from itself.
