These units have dimensions of energy divided by time and thus are units of power. They can be converted to SI power units by dividing by the number of hours in a year, about 8760 h/yr. Thus, 1 GWh/yr = 1 GWh/8760 h ≈ 114.12 kW.
Average power per capita was calculated according to the formula: [a] Electric energy per capita ... (GWh/yr) Year Source Population As of Consumption per capita
1 W·s = 1 J 1 W·h = 3,600 W·s = 3,600 J 1 kWh = 3,600 kWs = 1,000 Wh = 3.6 million W·s = 3.6 million J. Electric and electronic devices consume electric energy to generate desired output (light, heat, motion, etc.). During operation, some part of the energy is lost depending on the electrical efficiency. [5]
1.2 × 10 2: tech: electric power output of 1 m 2 solar panel in full sunlight (approx. 12% efficiency), at sea level 1.3 × 10 2: tech: peak power consumption of a Pentium 4 CPU 2 × 10 2: tech: stationary bicycle average power output [17] [18] 2.76 × 10 2: astro: fusion power output of 1 cubic meter of volume of the Sun's core.

> 2.4 × 10 −1: 280 GWh The typical energy yield of severe thunderstorms. [30] 1.5 × 10 −5 – 6 × 10 −1: 20 MWh – 700 GWh The estimated kinetic energy of tornados. [31] 1 1.16 TWh The energy contained in one megaton of TNT (4.2 PJ) is enough to power the average American household for 103,000 years. [32]
Concerning solar power, the estimate of €293/MWh is for a large plant capable of producing in the range of 50–100 GWh/year located in a favorable location (such as in Southern Europe). For a small household plant that can produce around 3 MWh/year, the cost is between 400 and €700/MWh, depending on location.
World electric generation by country and source in 2022 [1]. This is a list of countries and dependencies by annual electricity production.China is the world's largest electricity producing country, followed by the United States and India.
One terawatt hour of energy is equal to a sustained power delivery of one terawatt for one hour, or approximately 114 megawatts for a period of one year: Power output = energy / time 1 terawatt hour per year = 1 × 10 12 W·h / (365 days × 24 hours per day) ≈ 114 million watts, equivalent to approximately 114 megawatts of constant power output.
