The levelized cost of electricity (LCOE) is a metric that attempts to compare the costs of different methods of electricity generation consistently. Though LCOE is often presented as the minimum constant price at which electricity must be sold to break even over the lifetime of the project, such a cost analysis requires assumptions about the value of various non-financial costs (environmental ...
According to the U.S. Energy Information Administration (EIA), "Electricity prices generally reflect the cost to build, finance, maintain, and operate power plants and the electricity grid." Where pricing forecasting is the method by which a generator, a utility company, or a large industrial consumer can predict the wholesale prices of ...
One square metre of the Earth receives about 1.4 kilojoules of solar radiation every second in full daylight. [20] A human in a sprint has approximately 3 kJ of kinetic energy, [21] while a cheetah in a 122 km/h (76 mph) sprint has approximately 20 kJ. [22] One watt-hour, of electricity or any other form of energy, is 3.6 kJ. megajoule
The cost of a electricity production depends on costs during the expected lifetime of the generator and the amount of electricity the generator is expected to produce 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. [3]

The "megaton (of TNT equivalent)" is a unit of energy equal to 4.184 petajoules (4.184 × 10 15 J). [7] The kiloton and megaton of TNT equivalent have traditionally been used to describe the energy output, and hence the destructive power, of a nuclear weapon.
The data are given in kilograms of oil equivalent per year, and gigajoules per year, and in watts, as average equivalent power. Notes on conversions. 1 kg of oil equivalent (kgoe) = 11.63 kWh or 1 kWh = 0.08598 kgoe [2] 1000 kgoe = 42 GJ; 1 GJ/a = 31.7 W average; 1 W average = 8.76 kWh per year (365 × 24 Wh per year)
