Answer: It is any behavior that results in energy transformation.
Explanation:
a. Energy efficiency is a measure of energy used for delivering a given service.
b. Energy conversion efficiency is the ratio between the useful output and input of an energy conversion process.
c. Efficient energy use is related to any reduction in the amount of energy consumed in a process or system.
d. Energy conversion is is any behavior that results in energy transformation.
According to law of conservation of energy, energy remains conserved. It only transforms from one form to another. For example: When food is oxidized, the chemical energy stored in the bonds of food converts to kinetic energy which is the energy possessed by an object by virtue of motion.
