MYTH #1: Leaving a light on uses less energy than turning it off, then on again

Some people believe that if they leave the light on when they exit a room for a few minutes, it's better than turning the light off and then on again when they return. This is simply not true – it's always better to turn the light off.

There is no significant additional power draw when turning on a light bulb (other than the calories you use by flipping the switch). So, turn off the lights each time you leave a room, even if for just a couple of minutes.

    The biggest myth is the one perpetuated by the government and power authorities. It started with the use less water and we will not have to build more dams and your costs will go down............#$%$ Use less electricty and your costs will go down,........#$%$.The less you use the higher the tariffs as the privateers strive to make more money. When the cost of solar comes down and we all get off the grid that will be the only way to save money.You can do what you like with your own appliances and not be strapped into so called usage zones that are meant to save you money like doing your washing at 3AM in the morning or taking a shower once every three days.Its all counterproductive and the sooner we can all control our power supply the better. Did any one notice that AGL put up their prices by the same margin that it wil be reduced when the carbon tax is scrapped??? What a pack of morons we are wait for the local council to start charging you a tariff for not using power off the grid, its coming..

    If we all lived underground, like moles, we wouldn't need heating or cooling. Think about it.

    I think the most important 'myth' has been left out. Here it is: Myth #0: You need to be concerned about your electricity usage charge (rather than your meter charge). Have a look at your bills and you will notice that electricity providers charge you a lot PER DAY for the meter charge, i.e. for the infrastructure to supply you with electricity. For many units with only one or two occupants, you could end up paying more for the meter charge than for the electricity actually used. It's ridiculous! In that case, it is not that worthwhile to consider trying to save electricity at all!

    Paul, really, you're clearing your land of trees for warmth? That's eco-vandalism surely. I find it hard to fathom you admitting to it. If you're so worried about your carbon footprint, spare the trees. Most people know that trees reduce carbon. But I guess on planet Adelaide you still have some catching up to do.

    My late 1980s double brick house in the Adelaide hills rarely needs cooling, but I do rack up the bills in the winter when the outside temperature can be below 12C all day. Since the rise in electricity prices I've had to reduce using my air conditioning and resort to burning the Stringybarks all over my property in a combustion heater. So, cheaper electricity would reduce my carbon footprint, but all those trees mean my cost recovery time for solar panels would blow out to 10 years (I've had 8 quotes, and 3 of those quoting were honest enough to tell me so.)

    Gee what a helpful article, especially after watching tests done with turning a light off v left on, turns out it depends fully on what style of bulb it is. Here is a much better fatc that does reduce power bills, put in a 5 Kw solar unit & it will pay itself off by removing your bill fully. I did & ok I get a good rebate but even without the returns I get I would have zero bills, took 28 months for mine to pay itself off fully & power co,s hate it cause you are independant, just gotta sort the huge water bill now.
