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 proton–proton chain, also commonly referred to as the p–p chain, is one of two known sets of nuclear fusion reactions by which stars convert hydrogen to helium.
In astrophysics, stellar nucleosynthesis is the creation of chemical elements by nuclear fusion reactions within stars. Stellar nucleosynthesis has occurred since the original creation of hydrogen , helium and lithium during the Big Bang .
Elements of Solar Fusion. In the core of the Sun, fusion involves primarily hydrogen nuclei (protons). Under intense temperature and pressure, these protons overcome their natural repulsion to fuse into helium, the second-lightest element.
27 sie 2014 · The primary reaction is thought to be the fusion of two protons with the emission of a low-energy neutrino. These so-called pp neutrinos constitute nearly the entirety of the solar neutrino flux,...
14 sie 2020 · The principal source of energy in the sun is a net fusion reaction in which four hydrogen nuclei fuse and produce one helium nucleus and two positrons. This is a net reaction of a more complicated series of events: 411H He24 + 20+1n (20.9.1) (20.9.1) 4 1 1 H He 2 4 + 2 + 1 0 n.
Solar fusion 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 of two protons.
