The cost of energy production depends on costs during the expected lifetime of the plant and the amount of energy it is expected to generate over its lifetime. The levelized cost of electricity (LCOE) is the average cost in currency per energy unit, for example, EUR per kilowatt-hour or AUD per megawatt-hour. [5]
The per capita data for many countries may be slightly inaccurate as population data may not be for the same year as the consumption data. Population data were obtained mainly from the IMF [ 3 ] in 2021 with some exceptions, in which case they were obtained from the Wikipedia pages for the corresponding countries/territories.
