Electric power is the rate of transfer of electrical energy within a circuit.Its SI unit is the watt, the general unit of power, defined as one joule per second.Standard prefixes apply to watts as with other SI units: thousands, millions and billions of watts are called kilowatts, megawatts and gigawatts respectively.
Power in mechanical systems is the combination of forces and movement. In particular, power is the product of a force on an object and the object's velocity, or the product of a torque on a shaft and the shaft's angular velocity. Mechanical power is also described as the time derivative of work.

Total final consumption (TFC) is the worldwide consumption of energy by end-users (whereas primary energy consumption (Eurostat) [24] or total energy supply (IEA) is total energy demand and thus also includes what the energy sector uses itself and transformation and distribution losses). This energy consists of fuel (78%) and electricity (22%).
The US generated 772 TWh of nuclear power in 2022, surpassing China (395 TWh) and France (282 TWh). However, nuclear power constitutes a much smaller percentage of total power generation (18%) when compared to France (63%). [39] Nuclear had significant growth from the 70s through the 90s, but has stagnated since. [22]

In 2022, the total worldwide electricity production was nearly 29,000 TWh. [8] Total primary energy is converted into numerous forms, including, but not limited to, electricity, heat and motion. [9] Some primary energy is lost during the conversion to electricity, as seen in the United States, where a little more than 60% was lost in 2022. [9]
