Foot Switch Operated Mains Outlet
This is my favourite money saving device. I use remote switches but I found they didn't last long. This is a mechanical switch and except for a indicator to let you know it is on, uses very little power. Place the foot switch in a convenient location and power off the TV, DVD, Games units all with a single press of your foot. Use it to turn of your computer, monitor and printer. The savings in standby power should pay for this unit in around 6-12 months and then your savings will really add up. Those red lights you see on your devices in standby means you're paying money.

Watts Clever Mains power meter
They say knowledge is power, but in this case knowledge is less power. An easy to read screen means you can work out how many watts a device is using and then with the Energy Calculator you can work out which devices are costing you the most. I replaced my kettle so I could boil just the water I needed and that alone will pay for this unit every year. Once you know what a device is costing you, you can make better decisions.

Mains power meter
This is a lower cost power meter. The smaller display is harder to read, but since you'll only want a meter to measure devices once, this unit will pay for itself many times over. This unit helped me to reduce my electricity bill by over 50%. Our last electricity bill was 6.85kWh per day which is about 40% of the average for a family of four.

NOTE: These items are only available for sale within Australia.

Instructions:

Watts: Enter the watt rating for the appliance. For a light this is found on the light. For more complex items such as the standby power used by a television, you will need a device to measure the power.

Hours: Enter the number of hours you use the appliance for per day. If you use the appliance for less than an hour enter the time as a decimal. That is half an hour is 0.5. If you use the item once a week, or once a month, first divide the time by the number of days. E.g. Iron once a week for 2 hours. Divide 2 by 7 which gives 0.28 hours per day.

Price/kWh: This is the price the energy company sells electricity to you including GST. The default price is for Red Energy which is 21.45 cents as at 1 January 2011. This is not an endorsement for Red Energy, just a base rate to work with. Check your rate from your latest electricity bill. The price you enter will stay until you close the page.

Cost/Year: This figure is the cost per year of using the appliance.

Cost/Day: This figure is the cost per day of using the appliance.

Replacement unit payback period

Cost: This is the cost of the new appliance that you are thinking of buying to replace the existing appliance.

Watts: This is the watts used by the new appliance.

Savings per year: This is the savings made by using a lower energy unit. A negative value means it is costing more.

Payback period in months: This is how long it will take to pay off the new appliance based on the energy saved.
