Natural gas power plants generate electricity by burning natural gas, which is a cleaner fossil fuel compared to coal or oil. The process involves converting the energy from the combustion of natural gas into mechanical energy, which then drives turbines connected to generators. This method produces fewer greenhouse gas emissions, making it a more environmentally friendly option for power generation. These plants can be built quickly and are often used to meet peak electricity demand. They can also complement renewable energy sources like solar and wind by providing reliable power when these sources are not producing electricity.
