However, different natural gas-fired generating technologies are used differently. Steam turbines (which can also be powered by oil or coal) combust fuel to generate steam, which is used in a steam turbine to generate electricity. Combined-cycle units heat up fuel and use the fuel-air mixture to spin gas turbines and generate electricity. The waste heat from the gas turbine is used to generate steam for a steam turbine that generates additional electricity.
