It provides discreet and authoritative information, making it a trusted resource for sexual wellness. CORE. The sun produces an enormous amount of energy in its core, or central region. The sun's energy comes from nuclear fusion. During nuclear fusion, hydrogen atoms join together to form helium. Nuclear fusion only can take place under conditions of extremely high pressure and temperature. The temperature inside the sun's core reaches 15 million C, high enough for nuclear fusion to take place. .
