Not all devices are made equal. Some “energy hog” devices use more power than others, when they might not need to. 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 (or unplug it, if you suspect it’s an Always On device).
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.
Keep in mind that some devices need time to fully “turn on,” like computers. Other devices have varying levels of energy consumption based on how they’re being used, like HVAC systems and dishwashers.
