- "Natural gas power is cheaper than either coal and fission power because they both rely on big, heavy, expensive, inefficient steam turbines." Most natural gas power plants in the USA use steam turbines. The most common setup is a two-stage "combined cycle": first, an internal-combustion gas turbine, whose waste heat powers a lower temperature steam turbine. https://en.wikipedia.org/wiki/Combined_cycle_power_plant https://en.wikipedia.org/wiki/Combined_cycle_power_plant https://www.eia.gov/todayinenergy/detail.php?id=39012 https://www.eia.gov/todayinenergy/detail.php?id=39012 (~90% of natural gas kWh)
