What Does PJ Stand For?
PJ stands for Petajoule
A petajoule (PJ) is a unit of energy in the International System of Units (SI), equal to one quadrillion joules (10^15 joules). It is commonly used to quantify large-scale energy production and consumption, such as in electricity generation, heating, and fuel combustion. The petajoule is valuable in fields such as engineering, environmental science, and energy policy, providing a standard measure for comparing energy resources and efficiencies.
