Increase your home efficiency, reduce your carbon footprint and save money

The first step towards reducing our electricity consumption is to increase our knowledge and awareness.

For that, there is not better way than calculating how much electricity we are using and how much money our electricity consumption is costing us.

Before going ahead, we really recommend to first have a look to the Effiworkx YouTube channel videos. On those videos we explain concepts that will be of your interest.

Standby power consumption

What a Kilowatt Hour (kWh) is

Plug-in power meter

This calculator can be used to:

kW = W/1000

kWh = (W/1000) x Hours

kWh is the measurement unit used by the electricity suppliers to calculate our electricity bills.

Also, most of the big appliances, like the dishwashers or washing machines, rate their consumption in kWh.

This calculator can be used to:

P = V x I

This calculator can be used to:

V = P/ I

This calculator can be used to:

I = P / V

This calculator can be used to:

If you know the power ratings of a device, it is quite straight forward to calculate the electricity consumption. In order to calculate the electricity cost, you must know first how much you are paying per kWh.

We don’t recommend to use calculators to find out the electricity consumption of appliances like a washing machine, a tumble dryer or a dishwasher. The power consumption of those appliances may vary depending on the cycle settings so we recommend to use a plug in power meter which is a device which will provide much more accurate results.

This calculator can be used to:

This bulb wattage comparison table can be used as reference for the ‘Bulb power rating’ field. For example, if you have a 100 W incandescent bulb and you want to know how much you would be saving by replacing it by a LED bulb. First make the calculations using a ‘Bulb power rating =100’, take note of the results and afterwards make the calculations using ‘Bulb power rating =20’

Incandescent | CFL | LED |
---|---|---|

40 W | 8-12 W | 4-5 W |

60 W | 13-18 W | 6-8 W |

75 W | 18-22 W | 9-13 W |

100 W | 23-30 W | 16-20 W |

This calculator can be used to:

E.g. desktop printer, computer monitor, phone charger,…

Note that a device power consumption in standby mode it is most probably much lower than during normal operation. Therefore, in order to calculate the standby mode power consumption of a device over time, it is necessary to **find out the instantaneous power consumption while in standby mode**.

This calculator can be used to:

As an example, tumble dryer balls claim to reduce the drying time by 20%. That means potential savings of 20% on the tumble dryer cycle cost of 20%.

A 20% electricity consumption per cycle may not translate in big saving over short periods of time but it may represent significant saving over a longer period.
