Look closely at the chart above. Why is gas turbine power more expensive per kilowatt-hour than nuclear power?

Gas turbine power is more expensive per kilowatt-hour than nuclear power because the cost of natural gas, which is used as a fuel in gas turbines, tends to fluctuate more compared to the relatively stable fuel costs associated with nuclear power generation. Additionally, gas turbines have lower efficiency levels compared to nuclear power plants, resulting in higher operational costs. Lastly, building and maintaining gas turbine power plants typically require more frequent maintenance and replacement of components, adding to the overall operational costs.
