• Gigawatt hour (3,600,000,000,000 J)

  The gigawatt hour (symbol GWh) is a unit of energy equal to 3,600,000 megajoules. If energy is transmitted or used at a constant rate (power) over a period of time, the total energy in gigawatt hours is equal to the power in gigawatt multiplied by the time in hours.

• Terajoule (1,000,000,000,000 J)

  The terajoule (TJ) is equal to one trillion (10¹²) joules; or about 0.278 GWh (which is often used in energy tables). About 63 TJ of energy was released by the atomic bomb that exploded over Hiroshima. The International Space Station, with a mass of approximately 450 megagrams and orbital velocity of 7.7 km/s, has a kinetic energy of roughly 13 TJ. In 2017 Hurricane Irma was estimated to have a peak wind energy of 112 TJ.
