The energy from the Sun - both heat and light energy - originates from a nuclear fusion process that is occurring inside the core of the Sun. The specific type of fusion that occurs inside of the Sun is known as proton-proton fusion.

The Sun is a main-sequence star, and, as such, generates its energy by nuclear fusion of hydrogen nuclei into helium. In its core, the Sun fuses 620 million metric tons of hydrogen and makes 616 million metric tons of helium each second.
14 sie 2020 · The most important fusion process in nature is the one that powers stars. In the 20th century, it was realized that the energy released from nuclear fusion reactions accounted for the longevity of the Sun and other stars as a source of heat and light.
Today, we know that the sun, along with all other stars, is powered by a reaction called nuclear fusion. If nuclear fusion can be replicated on earth, it could provide virtually limitless clean, safe and affordable energy to meet the world’s energy demand.
Solar fusion proceeds through a three-stage process. First, two protons (hydrogen atoms stripped of their electrons) react to produce a deuteron, a positron and a neutrino. Then the deuteron, 2 H, captures a proton to form the helium isotope 3 He (helium-3), and then two 3 He nuclei fuse to form 4 He with the emission
