    Default Electricity usage (and costs) of common household appliances

    I thought this would be of interest to many people. It's a chart showing how much electricity household appliances use, and the (Eskom) costs of using those appliances (before price increases, of course.)

    My computer's stay on 24hours. Ofcourse the monitors goes into standby when not in use, but the towers stay on, the routers stay on. Wonder what that costs...

    Welcome to the club

    If they make an aircon which can run on solar power, that person'll be an instant billionaire

    apparently aircons don't use all that much, about R100 per month used daily for up to 8 hours... but don't quote me..

    My flatmate and I both had aircons installed in our bedrooms last year feb... they pretty much run 6-12 hours per day and fulltime on weekends, unless we go out for more then 1hour. I think our electric bill went up around about R200 per month if that. Won't quote me on that though as I don't really pay that much attention to the electric bill. Appart from the aircon usage there is not much we could do to reduce ours as we don't use a tv etc. Although we are thinking of getting a monochoice subscription before the super 14.

    Ok, this might be slightly off topic, but anyway.....

    Do any of you have experience with this thingie from Verimark?

    Reason I'm asking is with 5 people in the house, plenty of rainy days and our ancient tumbledryer on it's way out, we are looking for a solution that will use less power as well (a tumbledryer uses a LOT of power)....
