    I phoned the Municipality and according to the lady I spoke to our gate is locked every time they want to take a reading so they worked on estimated figures for my account! Now does that make sense out of the 4,000 + account? lol

    Apparently I can phone them the numbers in future, so I guess I will be doing that from now on... Mmmmmmmm I wonder how much money they owe me by now!

    Well, there are still quite a few ways you can shave some kWh off of your account, but I'll post more about that tonight.

    What is their last reading for your meter, and what is your current reading?

    0.8kW * 6hrs * 30 = 144kWh (swimming pool pump)
    You can try to figure out whether it is possible to run for fewer hours per day. It not, you can try to make sure this happens outside of peak hours (doesn't save energy, but helps Eskom). Also check out alternatives, such as salt chlorinators, and the Floatron.

    3kW * 4.3hrs * 30 = 387kWh (tumble drier)
    As Dave said, consider using a washing line. You'll save a lot of money.

    0.005kW * 24 * 30 * 4 = 14.4kWh (4 hi-fi's - on standby 24hrs a day)
    Make sure your hifi's (and anything else) is off at the wall plug when not in use.

    50kWh (fridge)
    I'm assuming that people use the fridge reasonable (i.e. open and close quickly - no starting for hours). You could probably save a little by upgrading your fridges to more modern energy efficient ones, but no need for this.

    0.2kW * 4 * 30 = 18kWh (computer @ 0.15kW + screen @ 0.05kW)
    0.04kW * 24 * 30 = 28.8kWh (computer, screen and peripherals while "off")
    0.85kW * 16 * 30 = 408kWh (4 computers @ 0.15kW + 5 screens @ 0.05kW)
    0.04kW * 8 * 30 * 4 = 38.4kWh (4 computers, screens and peripherals while "off")
    0.05 * 16 * 30 = 48kWh (2 laptops)
    0.1kW * 16 * 30 * 2 = 96kWh (2 printer/fax)
    Make sure your computers and peripherals are off at the wall plug when not in use. Also make sure that they are set for the highest energy saving (sleep after 15 minutes, no screen saves, power screen off after 15 minutes, hibernate after 30-60 minutes, power usage set to Minimal Power Management)
