What is wasted energy and how is it most often created?

It is still there but in different forms and spread out into the surroundings, so we refer to it as ‘wasted energy’. This wasted energy is often in the form of heat but could be in other forms like light and sound. One way or another, the energy that has been transferred to the surroundings makes them warmer.

How do you calculate wasted energy?

You can measure the input power by taking AC measurements, say 1A at 120VAC = 120 Watts. The wasted power is 120W – 102 W = 18 W. That power is lost as heat from the power supply. The other 102W becomes heat in the motherboard, which is considered the load and that the 102 W is used for doing useful work.
