All the SI prefixes are commonly applied to the watt-hour: a kilowatt-hour is 1,000 Wh (kWh); a megawatt-hour is 1 million Wh (MWh); a milliwatt-hour is 1/1,000 Wh (mWh) and so on. The kilowatt-hour is commonly used by electrical energy providers for purposes of billing, since the monthly energy consumption of a typical residential customer ...

In Western Europe, this is between 4 and 8 MWh/year. [8] (1 MWh = 1,000 kWh) In Scandinavia, the United States, Canada, Taiwan, South Korea, Australia, Japan and the United Kingdom, the per capita consumption is higher; however, in developing countries, it is much lower. [8] The world's average was about 3 MWh/year in 2022. [8]
Power is the rate at which energy is generated or consumed and hence is measured in units (e.g. watts) that represent energy per unit time. For example, when a light bulb with a power rating of 100 W is turned on for one hour, the energy used is 100 watt hours (W·h), 0.1 kilowatt hour, or 360 kJ. This same amount of energy would light a 40 ...
1 MWh = 0.086 toe [7] (therefore 1 toe = 11630.0 kWh) [8] At thermal power plants, 1 MWh is generated with 0.22 toe fuel or 0.39 MWh with 0.086 toe [9] (39% thermal to electrical conversion efficiency) Tonne of oil equivalent should be used carefully when converting electrical units.
The dimension of power is energy divided by time. In the International System of Units (SI), the unit of power is the watt (W), which is equal to one joule per second. Other common and traditional measures are horsepower (hp), comparing to the power of a horse; one mechanical horsepower equals about 745.7 watts.
