Devices left plugged in while turned off, sometimes called vampire loads, cost the average home around $100 a year in wasted electricity.
Find the culprits, which are usually chargers, game consoles, TVs, and anything with a clock or a glowing light.
Group electronics onto a power strip and switch the whole strip off when not in use, which turns five vampires into one easy switch.
Unplug rarely used chargers entirely, and the savings are small but completely free.
It is the easiest energy cut in the house, because it asks nothing of you but a flick of a switch.
