'''GTOE''' is an abbreviation for
"gigatonne of oil equivalent", a common measure of global
energy. A
billion tonnes of
oil contains roughly 10,000,000,000,000,000,000
calories (as in the energy to heat one gram of
water one degree
Celsius, not "Calories" as in the food measurement —also known as the kilocalorie) or 41.868 EJ (exajoules) or 11.63 PW·h (petawatt-hours). As of 2003, the world uses roughly 9 GTOE (380 EJ) worth of energy per year, from all energy sources combined with an annual growth rate of roughly 3%.
