The sun produces energy by the process of nuclear fusion. it happens when lighter nuclei combine to produce a larger, heavier nucleus. In the process, energy is released. Nuclear fusion requires very high temperatures and pressures.
The sun generates energy in its core in a process called nuclear fusion. During nuclear fusion, the sun's extremely high pressure and hot temperature cause hydrogen atoms to come apart and their nuclei (the central cores of the atoms) to fuse or combine.
Answer:Both renewable and nonrenewable resources can be used to generate electricity, as a heat source, and for vehicle fuel. ... The use of renewable resources typically has less environmental impact in the form of pollution than the use of nonrenewable resources.
