Energy consumption

Energy consumption is the amount of energy or power used.[1]

Biology

In the body, energy consumption is part of energy homeostasis. It derived from food energy. Energy consumption in the body is a product of the basal metabolic rate and the physical activity level. The physical activity level are defined for a non-pregnant, non-lactating adult as that person's total energy expenditure (TEE) in a 24-hour period, divided by his or her basal metabolic rate (BMR):[2]

{\text{PAL}}={\frac {\text{TEE/24h}}{\text{BMR}}}

Demographics

Topics related to energy consumption in a demographic sense are:

Effects of energy consumption

Reduction of energy consumption

Energy conservation, the practice of decreasing the quantity of energy used
Efficient energy use
