Flexi Says: Natural gas can be used as fuel. It burns more cleanly than petroleum and produces fewer greenhouse gases. Natural gas is delivered to homes, where it is used for cooking and heating. It is also a major energy source for powering turbines to make electricity. It releases most of its energy as heat when it burns. The power plant is able to use this heat, either in the form of hot gases or steam, to spin turbines. The spinning turbines turn generators, and the generators create electricity.
