Fusion energy is a form of power generation that mimics the processes occurring in the sun and other stars. It involves fusing two light atomic nuclei, typically isotopes of hydrogen such as deuterium and tritium, to form a heavier nucleus. For both phenomena, light is absorbed, causing excitation of an electron or other. Solar panels harness sunlight through the photovoltaic effect, converting solar energy into clean, renewable electricity for a sustainable future. The photovoltaic effect was first. Fusion energy, often referred to as the "holy grail" of energy production, promises virtually limitless power with minimal environmental impact.
