Total annual usage of energy by humankind is of the order of Terra Joules? true or false
Answers
"No, the total annual usage of the energy of energy by humankind is of the order of GigaJoules.
A human consumes total 2000 Kcal of energy.
1Kcal = 4100 Joules that means a human is consuming 4200 * 2000 = 8.4 * 10^6 joules of energy.
The annual consumption on the conversion to the units;
Kilo = 10³
mega = 10⁶
Giga = 10⁹
Terra = 10¹²
peta = 10¹⁵
exa = 10¹⁸
Hence the answer is 3.066 GigaJoules

The given statement is false.
The total annual usage of the energy by the humankind is of the order of GigaJoules.
An average human consumes total 2000 Kcal of energy for his daily usages.
1Kcal = 4100 Joules that means a human is consuming 4200 * 2000 = 8.4 * 10^6 joules of energy is 3.066 GigaJoules.
