Final answer:
Energy intensity is a measure of how much energy a society uses relative to its economic scale. Higher energy intensity indicates that a country is more resource-heavy in relation to its economy. Increased efficiency of energy use can change the dependency between economic well-being and energy consumption.
Step-by-step explanation:
Energy intensity is a measure of how much energy a society uses relative to its economic scale. It can be seen as an efficiency measure and is calculated by dividing the energy expenditure of a country by its gross domestic product (GDP). Higher energy intensity indicates that a country is more resource-heavy in relation to its economy. Increased efficiency of energy use can change the dependency between economic well-being and energy consumption.
