Without gravity we would HAVE NO LIVES. For instance, gravity keeps our Earth together; and gravity is an important component in making the Sun produce energy via nuclear fusion.
The Sun.
The sun consist primarily of a collection of hydrogen (about 75% of the mass of the sun). This energy is fused, or burned, into helium by the pressure of the weight (gravity) of the sun. This conversion of hydrogen into helium will go on for most of the sun's life time. This nuclear reaction can be thought of as the sun's internal energy.
Helium
The energy which produces light and heat in the Sun comes from "nuclear fusion" deep inside the Sun.
Fusion produces the Sun's energy .
the sun produces thermal energy
Nuclear fusion - that is the squeezing together hydrogen molecules in the Sun by the Sun's enormous force of gravity. This process releases a huge amount of heat.

heat
Solar energy is the heat that sun produces to any of the planets and it affects earth because its heating a lot our planet.
