"Gas-fired" refers to equipment or systems that use natural gas as a fuel source to generate energy or heat. This term is commonly associated with power plants, heating systems, and appliances like stoves and water heaters. Natural gas is favored for its efficiency and lower emissions compared to other fossil fuels. In the context of electricity generation, gas-fired power plants convert natural gas into electricity through combustion. These plants can quickly adjust their output to meet demand, making them a flexible option in the energy mix. Additionally, combined cycle gas plants utilize both gas and steam turbines to enhance efficiency, further reducing environmental impact.
