A quad is a unit of energy equal to 10 15 (a short-scale quadrillion) BTU, [1] or 1.055 × 10 18 joule (1.055 exajoules or EJ) in SI units. The unit is used by the U.S. Department of Energy in discussing world and national energy budgets. The global primary energy production in 2022 was 637.8 quad, i.e., 672.9 EJ. [2]

Major energy production or consumption is often expressed as terawatt-hours (TWh) for a given period that is often a calendar year or financial year. A 365-day year equals 8,760 hours, so over a period of one year, power of one gigawatt equates to 8.76 terawatt-hours of energy.
A unit of electrical energy, particularly for utility bills, is the kilowatt-hour (kWh); [3] one kilowatt-hour is equivalent to 3.6 megajoules. Electricity usage is often given in units of kilowatt-hours per year or other periods. [4] This is a measurement of average power consumption, meaning the average rate at which energy is transferred ...
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. The watt-second is a unit of energy, equal to the joule. One kilowatt hour is 3,600,000 watt seconds.
In March, Amazon Web Services bought a data center in Pennsylvania that is co-located with the Susquehanna nuclear power station; the plant produces 2.5 gigawatts and the data center’s seller ...
Energy figures are measured in BTU, with 1 BTU equal to 1.055 kJ and 1 quadrillion BTU (1 quad) equal to 1.055 EJ. Because BTU is a unit of heat , sources that generate electricity directly are multiplied by a conversion factor to equate them with sources that use a heat engine .
