What type of energy does the sun give off?

The sun gives off solar energy. The sun is a star that is a furnace in which hydrogen nuclei undergo fusion to produce helium along with rarer and heavier elements.

During the sun’s fusion process, 0.3 percent of the elements' mass is converted to energy. The sun emits energy in the form of a solid material, called plasma, along with a mixture of ions, electrons and neutral atoms. The plasma and mixture are emitted along perturbation in the sun’s magnetic field, which causes solar flares and coronal mass ejections. The sun also emits energy by radiation. The sun’s radiation is a heat energy that has no mass and travels at the speed of light.
