  • Thermal Power
    Thermal power is a power station in which heat energy is converted into electrical energy. In most cases, steam-driven turbines convert heat into mechanical energy, which is used as the middle of electrical energy. Water is heated, turned into steam, and drives steam turbines, which drive generators. After the steam passes through the turbine, it condenses in the condenser and then circulates to the heated place.
