 Efficiency
 Efficiency is a ratio of wanted effect out of the total effort. In terms of electricity, efficiency is calculated by the following formula.

Efficiency formula

Thus, the higher the efficiency, the more you save.

Where has the energy gone to?
During the conversion from AC to DC, some electrical energy is lost. This energy is transformed into heat energy.


Wasted energy as heat


By increasing the efficiency:

1. Less noise from your cooling fan as your system temperature is lower.
2. Less air conditioning required.
3. Less electricity used (for the same amount of output you intake less electricity), thus less power needed for the power plant to burn the coal, therefore lower CO2 is produced.
4. Save more money on bills.
