Light bulbs boost energy savings

2011-01-17 11:01

Johannesburg - Power utility Eskom says consumers have helped save 1 800 megawatts of electricity by replacing incandescent light bulbs with compact fluorescent lamps (CFLs) between 2004 and 2010.

CFLs use up to 80% less electricity than an incandescent light bulb.

It said about 43.5 million CFLs were between 2004 and 2010 as part of Eskom's efficient lighting programme.

Eskom claims that this is a world record as it is the highest number of CFLs rolled out in one country through a single campaign. Mexico is reportedly planning to roll out 30 million CFLs.

It again warned that the gap between supply and demand would remain tight until the first unit of the Medupi Power Station starts generating power in 2012.

The station is currently under construction in the Limpopo province.

Eskom's senior general manager of integrated demand management, Andrew Etzinger, said that the success of the programme is attributable to energy-conscious and environmentally concerned citizens.

"Even the smallest changes, when made collaboratively, can have a significant impact," Etzinger said.

Eskom said the growing demand for CFLs have led to reduced prices, from between R60 and R80 for a single bulb in 2004 to R15 currently.

    Sorry to say, but as my fantastic energy saving CFL bulbs blow (after costing me a heck of a lot of money and not lasting very long), I am replacing them with the old trustworthy, bright incandescent.

    Where's my rebate?

  • Wickus - 2011-01-17 11:48

    @Louis. You must have bought defective bulbs, because in my experience the CFL's do last a lot longer when working properly.

    Sorry to say it...but CFL s are a complete waste of money and contribute to pollution of our planet..they don t last...no where near the 6000hrs that are claimed...many pop within the first day of use and then you must ride out a fortune in petrol to go and argue with the shops to exchange them.The quality of light that they emit is terrible. I m going back to halogen and normal globes.

      Insanely_Sane - 2011-06-02 12:11

      the 6000hrs are based on a smooth flow of constant power. i suppose with all the spikes and dips eskom give us, every time our lamps blow due to inconsistent voltage supply, eskom should subsidize a replacement scheme. they are charging us plenty for the supply, let them cough up the subsidy. ITS COSTING US MONEY TO SAVE THEM MONEY AND THEY ARE CHARGING US MORE MONEY????!!!!

    Did the price of electricity come down as a result? No. Because we saved 1800 MW of power that Eskom can sell to it's corporate clients (like the aluminium smelters and mines) at rates far below that which citizens pay per KW. So actually, it's those companies who should have taken ads in the weekend papers to say thanks to we peasants for keeping them rich.

  • Wow - 2011-01-17 11:54

    @ Louis - perhaps get an electrician to check your house out, you are passing blame... @chewbacca - Your rebate is your reduced energy bill, fool !

  • Mikeh - 2011-01-17 11:54

    @Louis - I have been using CFL bulbs since 2003 and have only had to replace 2 in the whole house.

  • Malcolm - 2011-01-17 11:57

    @ Louis - feel the same, the bulbs are no longer long lasting, manufacturing decent bulbs has taken a back seat to manufacturing bulk to supply demand.

  • Johan v R - 2011-01-17 11:58

    If I was ESKOM, I would not brag too much about either the high number of these highly toxic CFL bulbs (LED's are much better for the environment) or about building another coal fired power station through which extensive parts of the beautiful north-western bushveld will be destroyed and its water sources over-utilised.

  • loodikris - 2011-01-17 11:59

    e-WONDAFUL....with about 5mg of mercury per bulb what disposal/recycling options are available? Do we really care?...

  • Disalutioned SA - 2011-01-17 12:13

    What rebate, we put a solar geyzer on our roof last year, the elctrical company did not even apply for the rebate or inform us how we should go about claiming it. Our elecftrical companies are useless.

  • NN - 2011-01-17 12:17

    @ louis - My free eskom CFL's have been going for 3 years without one issue. Both my houses are all CFL's, and I havent replaced them once.

  • Philip - 2011-01-17 12:19

    I am still waiting for Eskom to advise the SA public on how to safely dispose of CFL bulbs. CFLs do not like being constantly switched on and off so you need to leave them on during the evening until snooze time.

  • cr1t - 2011-01-17 12:39

    I think it's time to ban incandescent light bulbs at least those from 60 and more watts.

  • Jan Alleman - 2011-01-17 12:49

    LED lamps will probably replace CFL lamps, once the technology becomes more affordable. They use even less energy and are extremely reliable, unfortunately they cost you an arm and a leg...

  • William S - 2011-01-17 12:56

    @ Louis....was "made wise" by a "bright sparky" (pun intended) I stopped buying CFL bulbs-all be they brand names-from group stores. I buy them from good electrical shop. He was correct....P&P may sell Osram(for example) but there is Osram and there is OSRAM...manufactured in different countries and way different quality. Solved the problem for me. NOW, ESKOM...I turned off one geyser(meant replumbing the house), lagged the pipes,use a geyser blanket,installed a timer,use CFL's only, turned off the pool pump for up to six days per week(weather conditions dictate)unplugged all appliances not in use,walk around with a flashlite to save switching on lights,installed an energy saving shower rose-only shower,never bath- and installed a gas stove(expensive!!)-managed to cut my power consumption by at least two thirds....my reward: you increase the tariff every year for the next three years....would you consider a rebate if I start using candles and taking cold showers?.....p.s.The TV only gets switched on for the ODI's,it is all that there is worth watching on SABC TV anyway:)

  • TerryT - 2011-01-17 12:58

    The CFL bulbs only last a fraction of their claimed life-span and they are much more expensive. In fact, as far as life span goes, I think they should be investigated in the same way the underweight bread was. I am also returning to the more reliable incandesent.

  • KR - 2011-01-17 13:00

    "as part of Eskom's efficient lighting programme" LOL. Yeah right, more like if you don't reduce electricity you will have black outs...again!

  • p_f_l - 2011-01-17 13:12

    I'm no engineer, but in my limited knowledge a megawatt is a unit of power, not energy. Shouldn't it be 1 800 megawatt-hours saved? And shouldn't one link the saving to a specified time period, e.g. in the last financial year? Or do they perhaps mean peak demand has reduced by 1 800 megawatts since the compact fluorescent lamps have been introduced? Can the bright engineers out there help me out on this one please? :)

  • Fr8er - 2011-01-17 13:16

    On the contrary, I find them to last particularly well and they are no longer all that expensive.

  • ROB - 2011-01-17 13:24

    Louis your house is wired for 220Volt how do you expect a 24Volt globe to work on 220Volt supply don't be cheap pay the extra and get 220Volt globes

  • Pioff - 2011-01-17 13:37

    In full agreement with Louis. CFL's do not last and you cant use them on light dimmers. Where do you get them for R 15.00 ??

  • William S - 2011-01-17 13:51

  • Safriken - 2011-01-17 14:05

    And has Eskom ever told us how many of these 43.5 million are still in use today? And then are they all working 24 hours per day, or at least all working at the same time? Because if they are not then they have not saved the 1,800 Megawatts as claimed! Saving an ad-hoc watt here and there does not help (even if in large numbers), our corporate friends that run lights 24 hours a day should convert their lighting to LED, then the savings will be real! @loodikris -yes we care if we have already received 43.5 million x 5mg's (and the intial batches had loads higher mg's) plus the 5 to 15 million CFLs the retailers sold per year. Then the 5mg's do make a difference. And the normal fluorescent tubes with their mercury content. And then just to make it interesting go and find out how much mercury is released at the coal-burning power stations per kW of electricity produced, now that is scary!

    I replaced a lot of halogen downlighters with LED's so instead of 50 watts I only use 6 watts each and use less LED's to light up the same area as the halogens ( wider light angle allows this). Yes they cost R 250 each but have a slow start, are dimmable and don't generate loads of heat but are direct drop in replacements. I don't have any incandesant bulbs active in my house, use gas to cook and have two geyser blankets on the geyser. Many have said - as much as we spend money to save on power usage, Eskom calws back very quickly in increased tarrifs - not to mention the municipalities jacking up their mark up at the same time so you don't notice! I am looking for an LPG powered generator to offset the coming spates of sudden domestic darkness! Anyone know where to get one? If you want LED's like I have - www.ledvsbulb.co.za

  • chetaahh - 2011-01-17 14:40

    CFL globes are a waste of money and they deffinitly dont last the promised 6000 Hours. And do you know why, because the manufacturers are creaming it with all the new sales. @louis and all other saying it dont last you are correct. @ wickus you obviously dont have any experience.

  • Roelof - 2011-01-17 14:59

    I'm an electrician and use incandescent lights due to the fact that they give better light almost immediately while CFL's must heat up first. CFL's don't last. Nothing wrong electrically, even got surge arrestors, but they keep on popping. Just the phillips ones I bought from WW that last about a month. Bought 1000 incandescent bulbs (100watt) for 50 cents each a while back, so there's more than enough bulbs left. Then again at the price of cfl's, it's cheaper to run incandescent than cfl.

  • Kevin - 2011-01-17 16:20

    OSRAM OR NOTHING

  • King Shaka - 2011-01-17 16:25

    @p_f_l Basic physics states that power is a time differential of energy. ie d/dt(Energy)[Joules] = Power (Watts). Therefore Power is energy spent/generated per unit time. They could have said "these bulbs have helped us save x amount of energy in x amount of time", but they chose to state it in terms of power. This is correct. A megawatt-hour is merely a unit of energy. You can't use a reference time/period when using this unit.

    LED is nice but is expensive
