What Is Fusion Power and Can It Replace Fossil Fuels?

TL;DR

Fusion power has the potential to provide clean, unlimited energy by mimicking the sun's nuclear fusion process. While current technology allows scientists to achieve fusion, it remains expensive and unproven for commercial use, making its viability uncertain. If successful, it could utilize hydrogen isotopes from seawater and lunar Helium-3, but high costs pose significant challenges.
