Comparative overview of three power generation pathways: thermal plants burning fossil fuels, geothermal systems extracting Earth's heat via production and injection wells, and biomass plants converting organic feedstock through preprocessing and gasification. Each pathway follows a common conversion chain—heat source to steam generation to turbine-driven mechanical energy to grid electricity—but differs in fuel input, extraction method, and sustainability profile. This architecture helps engineers evaluate trade-offs in efficiency, environmental impact, and operational complexity across conventional and renewable power technologies.
