For reference, about 10,000 100-watt lightbulbs or 5,000 computer systems would be needed to draw 1 MW. Also, 1 MW is approximately 1360 horsepower . Modern high-power diesel-electric locomotives typically have a peak power of 3–5 MW, while a typical modern nuclear power plant produces on the order of 500–2000 MW peak output.

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.

Megawatt-hours (MWh), gigawatt-hours (GWh), and terawatt-hours (TWh) are often used for metering larger amounts of electrical energy to industrial customers and in power generation. The terawatt-hour and petawatt-hour (PWh) units are large enough to conveniently express the annual electricity generation for whole countries and the world energy ...
One terawatt-hour, of electricity or any other form of energy, is 3.6 PJ. exajoule The 2011 TÅhoku earthquake and tsunami in Japan had 1.41 EJ of energy according to its rating of 9.0 on the moment magnitude scale. Yearly U.S. energy consumption amounts to roughly 94 EJ, and the world final energy consumption was 439 EJ in 2021. [27]
Certain onshore wind farms can reach capacity factors of over 60%, for example the 44 MW Eolo plant in Nicaragua had a net generation of 232.132 GWh in 2015, equivalent to a capacity factor of 60.2%, [7] while United States annual capacity factors from 2013 through 2016 range from 32.2% to 34.7%.
In the context of domestic PV installations, the kilowatt (symbol kW) is the most common unit for nominal power, for example P peak = 1 kW. Colloquial English sometimes conflates the quantity power and its unit by using the non-standard label watt-peak (symbol W p), possibly prefixed as in kilowatt-peak (kW p), megawatt-peak (MW p), etc.
