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. The watt-second is a unit of energy, equal to the joule. One kilowatt hour is 3,600,000 watt seconds.
The kilowatt-hour is a composite unit of energy equal to one kilowatt (kW) sustained for (multiplied by) one hour. The International System of Units (SI) unit of energy meanwhile is the joule (symbol J). Because a watt is by definition one joule per second, and because there are 3,600 seconds in an hour, one kWh equals 3,600 kilojoules or 3.6 ...
In English, the prefix giga can be pronounced / ˈ ɡ ɪ ɡ ə / (a hard g as in giggle), or / ˈ dʒ ɪ ɡ ə / (a soft g as in gigantic, which shares giga 's Ancient Greek root). [5] A prominent example of this latter pronunciation is found in the pronunciation of gigawatts in the 1985 film Back to the Future.
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.
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.
Amazon has similarly big plans to scale its latest green gamble, promising to build 5 gigawatts ― equal to 5,000 megawatts ― of new nuclear power plants in the U.S. over the next 15 years ...
TNT equivalent is a convention for expressing energy, typically used to describe the energy released in an explosion.The ton of TNT is a unit of energy defined by convention to be 4.184 gigajoules (1 gigacalorie), [1] which is the approximate energy released in the detonation of a metric ton (1,000 kilograms) of TNT.
Two gigawatts are equal to about 620 utility-scale wind turbines, according to the U.S. Office of Energy Efficiency and Renewable Energy. Shannon Marvel McNaught reports on Sussex County and beyond.
