A kilowatt-hour (unit symbol: kWâ h or kWÂ h; commonly written as kWh) is a non-SI unit of energy equal to 3.6 megajoules (MJ) in SI units, which is the energy delivered by one kilowatt of power for one hour. Kilowatt-hours are a common billing unit for electrical energy supplied by electric utilities. Metric prefixes are used for multiples and submultiples of the basic unit, the watt-hour (3.6 kJ).

đ Terawatt-hour in the context of Nuclear power in Russia
Russia is one of the world's largest producers of nuclear energy. In 2020, total electricity generated in nuclear power plants in Russia was 215.746 TWh, 20.28% of all electric power plant generation. The installed gross capacity of Russian nuclear reactors was 29.4 GW as of December 2020.

Terawatt-hour in the context of Electric energy consumption
Electric energy consumption is energy consumption in the form of electrical energy. About a fifth of global energy is consumed as electricity: for residential, industrial, commercial, transportation and other purposes. The global electricity consumption in 2022 was 24,398 terawatt-hour (TWh), almost exactly three times the amount of consumption in 1981 (8,132 TWh). China, the United States, and India accounted for more than half of the global share of electricity consumption. Japan and Russia followed with nearly twice the consumption of the remaining industrialized countries.
While power is measured in watts (W) or kilowatts (kW), energy consumption is typically measured in watt-hours (Wh) or kilowatt-hours (kWh). The relationship is fundamental: energy (E) equals power (P) multiplied by time (t):
Terawatt-hour in the context of Wind power in the United States
Wind power is a branch of the energy industry that has expanded quickly in the United States over the last several years. In 2024, 453.5 terawatt-hours were generated by wind power, or 10.54% of electricity in the United States. The average wind turbine generates enough electricity in 46 minutes to power the average American home for one month. In 2019, wind power surpassed hydroelectric power as the largest renewable energy source in the U.S. In March and April of 2024, electricity generation from wind exceeded generation from coal, once the dominant source of U.S. electricity, for an extended period for the first time. The federal government and many state governments have policies that guide and support the development of the industry, including tax credits and renewable portfolio standards.
As of December 2023, the total installed wind power nameplate generating capacity in the United States was 147,500 megawatts (MW), up from 141,300 megawatts (MW) in January 2023, although total energy generation declined slightly due to weather conditions. This capacity is exceeded only by China and the European Union. Thus far, wind power's largest growth in capacity was in 2020, when 16,913 MW of wind power was installed. Following behind it were 2021, during which 13,365 MW were installed, and 2012, which saw the addition of 11,895 MW, representing 26.5% of new power capacity installed in 2012.
Terawatt-hour in the context of Nuclear power in France
Since the mid-1980s, the largest source of electricity in France has been nuclear power, with a generation of 379.5 TWh in 2019 and a total electricity production of 537.7 TWh. In 2018, the nuclear share was 71.67%, the highest percentage in the world.
Since June 2020, it has 56 operable reactors totalling 61,370 MWe, one under construction (1630 MWe), and 14 shut down or in decommissioning (5,549 MWe). In May 2022, EDF reported that twelve reactors were shut down and being inspected for stress corrosion, requiring EDF to adjust its French nuclear output estimate for 2022 to 280â300 TWh; the estimate of the impact of the decrease in output on the Group's EBITDA for 2022 was assessed to be ââŹ18.5 billion.
