the sun generates energy by slowly contracting in size, called gravitational contraction-the gradually shrinking sun would always have some gas moving inward, converting gravitational potential energy into thermal energy (keeps sun hot)-because of the suns large mass it only has to contract very slightly to maintain temperature
In this way, the sun is slowly converting its mass into energy in the form of sunlight, and it has more than enough fuel to last billions of years. But nuclear fusion''s no walk in the park. On Earth, we need to heat hydrogen up 100 times hotter than the sun to get a fusion reaction. So how does the sun do it? Quantum tunneling.

Both processes release energy but differ in their underlying principles and the elements involved.
Oct 22, 2024· Both of these fusion reactions are exoergic and so yield energy. The German-born physicist Hans Bethe proposed in the 1930s that the H-H fusion reaction could occur with a net release of energy and provide, along with subsequent reactions, the fundamental energy source sustaining the stars. However, practical energy generation requires the D-T reaction for two
Fusion reactions power the Sun and other stars. In fusion, two light nuclei merge to form a single heavier nucleus. The process releases energy because the total mass of the resulting single nucleus is less than the mass of the two original
Dec 14, 2022· Nuclear fusion is the process which gives the Sun its energy. Nuclear fusion does not rely on fossil fuels like oil or gas, and produces none of the greenhouse gases which drive global warming.
Oct 15, 2017· Nuclear energy is what powers the sun. The material of the sun (primarily hydrogen) contracted into into itself by gravitation to form the body. The extreme pressure forced the hydrogen atoms to fuse (fusion) into helium, releasing huge mounts of energy. As stars age this process not only continues, but advances to the formation of heavier elements as well.
Feb 26, 2024· Most of the energy from the Sun and other stars comes from a chain of nuclear fusion reactions. The end of this chain is marked by the fusion of protons with beryllium-7 to form boron-8. This process is key in determining the flow of high-energy solar neutrinos that reach the Earth. The low-energy conditions under which these reactions take
Nuclear energy is energy made by breaking the bonds that hold particles together inside an atom, a process called "nuclear fission." This energy is "carbon-free," meaning that like wind and solar, it does not directly produce carbon dioxide (CO 2) or other greenhouse gases that contribute to climate change. In the U.S., nuclear power provides almost half of our carbon-free electricity.
