Suggested Review – :004, :005

1:5:10:019 Tip: Today you should familiarize yourself with using your watt use monitor. This is the device I encouraged you to purchase in :005.

Begin by plugging it into an outlet and plugging a standard lamp into the meter. Follow the instructions and try pressing the various buttons to see how it works. The digital readout should closely match the wattage of the light bulb. By pressing the “kilowatt hour/time” button once it should indicate the number of kilowatts used. Pressing the button again should indicate the time that has passed.

Try plugging a number of appliances into your meter and record in your journal how much power they use when they are both on and off in standby mode. For example my computer, monitor and printer use a total of 150 watts when they are on and 10 watts when in standby mode. This is pretty good compared to another computer, monitor and printer that use a combined total of 350 watts when on and 40 when in standby mode.

That 40 watts is the trickle current that is wasted energy. By turning this computer and it’s peripherals off any time it is not being used by flipping a power-strip switch, I could save about $80 a year.

I will be discussing many other ways to use your wattage monitoring meter in future 1:5:10:365 Tips.
