Fusion energy is a form of power generated by fusing atomic nuclei, a process that occurs naturally in stars, including our sun. This method has the potential to provide a nearly limitless source of energy with minimal environmental impact, as it produces very little radioactive waste compared to traditional nuclear fission. The primary fuel for fusion energy is isotopes of hydrogen, such as Deuterium and Tritium. When these isotopes collide at extremely high temperatures, they can overcome their natural repulsion and fuse together, releasing vast amounts of energy. Researchers are actively working on technologies like Tokamaks to make fusion a viable energy source for the future.
