Total production costs (in 2012 cents per kilowatt-hour)
Share:
In 2012, petroleum had the highest electricity production costs (operations & maintenance costs + fuel costs) at 22.48 cents per kilowatt-hour, and nuclear-generated electricity had the lowest costs at 2.4 cents per kilowatt-hour. Petroleum-generated electricity production costs have more than tripled since 1995 while nuclear-generated electricity and gas-generated electricity costs have decreased.
