Capital cost of energy production in the U.S. 2021, by technology
Nuclear energy has the highest estimated capital costs of any energy technology used in the United States. As of 2021, capital costs for nuclear power plants ranged between 7,800 and 12,800 U.S. dollars per kilowatt. As the radioactive materials used and the waste created require careful handling, nuclear stations are among the most expensive to built. The number of U.S. nuclear power plants fell to 93 in 2021, from 112 plants in 1990.
