WHAT IS EFFICIENCY?
Efficiency is a measure of return on investment. Every process – whether lighting a light bulb or running a car – requires some amount of energy “investment” to perform, but only a fraction of that energy actually goes on to do useful work like illuminating your room or moving passengers down a highway. The useful work performed divided by the original total energy investment (usually expressed as a percent) is the energy efficiency.
