one more reason to conserve electricity

If you like having a lot of electric appliances running around the house, plus lights and fans and AC’s (or heaters as the case may be), a look at the following graph might make you reconsider just how many things you leave on.

electricity_usuage.jpg

Based on rates as of 24/2/2007, the graph shows how the cost of electricity rises per 100 kWh of usage. (For more information on just how much electricity is 100 kWh, click here). As you can see, the largest gain is when you go upwards of using 300 kWh, where costs increase by almost 40% per kWh, compared to the 27% or 13% from 100 kWh or 1000 kWh upwards respectively.

These costs do not include meter rent (~Rs.20), sales tax (15%) or applicable income tax deductions.

So the next time your electrical bill soars, think about where your electricity is going in the first place. The more electricity you use, the exponentially your costs go up.

Some kWh calculations for common household items (running for 10 hours a day) are

  1. One 1.5 Ton AC = 2 kWh or 600 kWh / month
  2. One 100 watt lightbulb = 0.1 kWh or 10 kWh / month
  3. One 25 watt tubelight = 0.025 kWh or 7.5 kWh / month

To find out how much electricity each appliance is using, look for ‘watt’ reading on its label. This is the number of watts consumed in an hour. If watt is not given, multiply the Ampere and Voltage readings (e.g. a 1.5 ton AC works on 9.1 Ampere on 220 Volts, making it 2002 watts). To find out how much kWh it will use in a month, running at 10 hours per day, multiply this rating by 0.3.

    Leaving your desktop computer on for 24 hours a day for the whole month consumes 108 kwh

    Can someone please calculate how much we can save by turning off our wireless routers and cable modems off at night?

    Electricity hai kahan conserve karnay kay leey?

    The point I want to raise is extra usage of electricity for commercial usage. If you have noticed that in shops of Tariq Road, Clifton or even at a “Thela of Pan Wala“ you will find multiple bulbs/tubes/energy savers. Even, when you discuss with them you will find these all extra lighting are not for more brightness but only for decoration purpose….

    next we’ll hear “PM urges nation to curb use of flour” then next it’ll be restriction on use of electricity and finally water..

    Energy conservation aside, renewable energy really needs to be introduced in Pakistan. That’s the only practical solution to our energy crisis. An interesting note: a fairly new technology is burning garbage to produce renewable, environmentally-friendly electricity (www.wikipedia.org/wiki/mainpage/Incinerator). At the current rate of garbage Karachi produces, even if we separate the recyclables from the waste (which we should) we’ll have enough garbage to provide electricity to a large portion of the city.

    @D0CT0R …lol…seriously, have you completely lost it ? when did conservation become a bad thing ?

    most of the “developed” nations all urge their citizens to cut down on car usage. If you feel like arguing for the sake of arguing, a better argument would be that the government should first provide higher quality public transport, and then encourage a cut down in vehicle usage.

    And yes moronic D0CT0R, conservation in electricity usage and water usage isnt such a bad idea either. THE RICK COUNTRIES DO IT, how do you propose that Pakistan should just keep providing for you hunh??

    I wish there was a way or restricting D0CT0R’s posting priviliges, he is seriously just a dude upset with his own life, and his only joy left is ranting about each and every topic on KMB. Oh yeah, he also occasionally enjoys liking everything to Musharaff or the MQM. Good for you D0CT0R.

    shutting down power unplugging from outlet – ! shall be practiced. Instead of leaving in STANDBY,

    of domestic appliances, office equipment (laser printers, photocopiers, scanners)

    usage of energy saver lamps shall be adopted, it comes in 3 different variations – with marking on the box – Blue for white, Yellow for warm, Orange for sodium – power consumption remains the same, with high candle power.

    make HABIT of shutting down lights, fans, equipment when not in use, – usually dresser, bathroom lights and exhaust fans are left ON, without intention and goes unattended for hours, which is again a wasteage.

    Practice caution for usage be it water, electricity, gas –

    Next Global war is already ON for control of natural resources,

    @Ali K as you rightly pointed out that until govt is unable to provide some suitable alternate mode of transportation to public ,it simply suit them to ask public to cut down use of cars.. when PM and Mush’s motorcade of gas guzzlers exceeds 100s of cars then they should not be preaching the public to cut down the car use


  16. d0ct0r (unregistered) on January 10th, 2008 @ 6:00 pm

    @Ali K i think that racist and ethnic crap that your love spreading is really getting to your head, i was just emphasizing that these leaders should need to set example for public to follow instead of other way around…


  17. Reality_check (unregistered) on January 10th, 2008 @ 6:24 pm

    HITMAN there was a time when Mush just arrived as CEO, back then he was all for minimum protocol and did not want even the signals to favour his entourage when he was travelling. Then there was the first attempt on his life, followed by the second and the third and the reality of Pakistan quickly set in.

    As for conservation mass transportation is the key, but taking a walk to get the bread from the corner store will add to your health as well yours and the nations pocket.


  18. d0ct0r (unregistered) on January 10th, 2008 @ 7:09 pm

    now a ban have been imposed on pillion riding to deter terrorists.. offcourse it won’t affect Mush , PM Altaf bai or the governor, the real sufferer will be poor public which will have to travel on the roof of minibuses..


  19. d0ct0r (unregistered) on January 10th, 2008 @ 7:15 pm

    while PM preaches the public to cut down car usage and skip meals to control shortages he himself is busy buying 2 VVIP luxury helicopters worth $60 million..


  20. d0ct0r (unregistered) on January 10th, 2008 @ 7:29 pm

    already pakistani tax payers money is being used for maintaining a fleet of 14 luxury jets and a new jet worth $60 million was recently added..we are a poor nation with spoilt dictators ruling us

    Comments from d0ct0r:
    – “ban have been imposed on pillion riding ”
    – “PM preaches the public ”
    – “we are a poor nation with spoilt dictators ruling us”

    As usual always off-topic and on top of that nothing new (already published online or on print media). Dear this not a newpaper site.

    I have got an interesting question. Govt is urging for Energy savers, have they removed Duties and taxes from energy saving appliances or not?

    Doctor dude you are an idiot and you really do live in your own little pathetic sad world. Stay there :0
