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.
The average fuel burn of new aircraft fell 45% from 1968 to 2014, a compounded annual reduction of 1.3% with variable reduction rate. [33] By 2018, CO 2 emissions per revenue ton-kilometer (RTK) were more than halved compared to 1990, at 47%. [34] The aviation energy intensity went from 21.2 to 12.3 MJ/RTK between 2000 and 2019, a 42% reduction ...
One measure of alternative fuels in the U.S. is the "gasoline-equivalent gallon" (GEG). In 2002, the U.S. used as motor fuel, ethanol equal to 137,000 terajoules (3.8 × 10 10 kWh), the energy equivalent of 1.13 billion US gallons (4.3 gigalitres) of gasoline. This was less than 1% of the total fuel used that year.
