Find out how much energy you consume

December 27, 2006

Given below is the energy consumption of our daily household gadgets – ranging from the innocuous mosquito repellent to energy guzzler like a kettle or a geyser. Check how much you use on a monthly basis. It will help you save on precious power.

Did you know that:

  • A computer monitor left on overnight wastes enough energy to laser print 800 sheets of paper?
  • A photocopier left on overnight wastes enough energy to make 5300 copies?
  • A Low Energy Lightbulb uses 5 times less electricity than an ordinary bulb and lasts 10 times longer?

Now you can make your own list…whether it’s to find out how much you spend by running that huge refrigerator and air-conditioner, ironing your own clothes, or to save on the energy costs of running your washing machine….for example if you buy a model which does not automatically heat water, you will save a lot on electricity. This chart will give you everything – information on your innocuous ceiling fan to a toaster, immersion rod, hot plate, mixer, vacuum cleaner, tape recorder, video player (VCD) and yes even mosquito repellent and Night Lamp!

To read the chart: The column on the left which says ‘Wattage‘ is one which tells you the wattage of your appliance and this is usually found on the appliance itself. This determines how much electricity you consume. For example a 25 watt bulb, if used for just 1 hour a day for one month (monthly use) will consume .75 KWh (second column gives this figure) and it will take 40 hours to consume 1 whole unit (third column) =1000KWh. As the electricity company charges you per unit, this is what you need to know to calculate how much it costs you.



1. Wattage ratings differ from model to model
2. Electricity is measured in Kilowatt Hours (kWh) and is calculated by multiplying the watt rating by the number of hours the machine runs and dividing this by 1000
3. When 1000 watts are used (also called IkWh of electricity), 1 unit of electricity is consumed. (1 kWh=1 unit of electricity)

    Above info is really helpful for peoples.

    It’s really strange that we are having load shedding hours from 4 to 10. On top of this, some villages are getting the electricity hardly for 6 to 8 hours.
    We, as a good citizen, should also limit the use of electric equipments. Whenever possible we should try to save electricity by
    · Using staircase instead of elevators (if possible)
    · Minimizing use of Air Conditioners or restricting the temperature level by AC to certain value
    · Switching off the domestic equipments whenever not in use, such as TV, Fans, Lights
    · Switching off the monitor whenever not in use.

    Thanks for the info Vichavan. 🙂 – Nita.

    My attention was drawn to this post because of Vivachan’s comment. In the absence of formatting (probably lost in reflowing), the data are not easy to understand. It would be helpful if you could either post the chart again, properly formatted, or give a sample of “how to read” any one line. Perhaps a scan of the entire Raymond chart?

    Vivek, thanks for bringing it to my notice. When I changed the theme, the formatting of the chart must have changed!! thanks a lot!! – Nita.

    Can i please know that the monthly usage you have calculated , is based on the working of the aplliance on full wattage e.g. an AC with 1800 watts uses to its full capacity?

    Well as far as I know the wattage is given for its full capacity. In the case of the AC one assumes that one is using the coldest setting. On a lower setting the AC should consumer less power – Nita.

    The whole thing was a good piece of information which we usually tend to bypass. Hope I can put the energy saving procedures into practice from today itself
