The world s largest nuclear fusion project that will replicate reactions in the sun to create the ultimate clean energy source has begun assembly in france. Inside the sun this process begins with protons which is simply a lone hydrogen nucleus and through a series of steps these protons fuse together and are. 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.
An important fusion process is the stellar nucleosynthesis that powers stars including the sun in the 20th century it was recognized that the energy released from nuclear fusion reactions accounts for the longevity of stellar heat and light.
