To get an idea of what’s currently using electricity (and how much it’s costing you), take a walk around your home and investigate.
Wait until your Power Meter is relatively flat.
Turn a device on.
Watch the wattage change in the Power Meter and record the difference. That’s how much energy that device was using.
Turn the device off. Redo steps 2 and 3 a couple of times to get a more accurate average.
If the 120W device we found above runs for 6 hours a day, that’d cost us over $31 a year. Play around with the calculator below to figure out what your devices might be costing you.
Assuming the national average rate of $0.12/kWh
Usage in Watts:
Hours per day:
