Useful energy: The energy that support television to work is from the plug for the total input. In the other hand, the useful output energy are for the monitor’s liquid crystal and the chip to operate.

Wasted Energy: Beside the useful energy output, the heat from the television produce to work are one of the wasted energy. Also the wire lines that will wasted some energy through the conduction.

Improvement: The device can own the certification of higher conversion rate. We can use the power meter to measure the waste of energy.

Useful energy: The energy that light up the incandescent is from a plug which is just electricity energy. The thing in the incandescent that is getting light up is the little wire ish thing in the middle.

Wasted Energy: A lot of the energy wasted is from thermal energy. The disadvantage of using this kind of lightbulb is that it creates a lot of useless thermal energy and get heat up a lot.

Useful energy: energy that supports the operation of the computer, for example display, sound, and light

I thing this machine is kinda perfect.
