The video tutorial explains nuclear energy, its existence in atoms, and how it is stored in the nucleus. It covers nuclear fusion in the sun, where hydrogen nuclei join to release energy, and nuclear fission, where splitting an atom's nucleus releases heat energy. The process of generating electricity in nuclear power plants through uranium fission is described, highlighting the use of steam to spin turbines. The video concludes by emphasizing nuclear energy as the most concentrated form of energy available today.
