Should I be unplugging unused devices and electronics?
All things plugged in will bleed some energy. Called “standby” electricity loss because it’s so often associated with electronics in standby or idle mode, it’s also known as “phantom” energy. Even turned off, many appliances keep drawing power.
Power supplies don’t just convert energy; they consume it. Anything with a transformer draws power as long as it’s plugged in. And because of poor design, these boxes waste up to three-fourths of the electricity that passes through them. Unplug 10 of those black box transformers and you save, depending on how much you pay for electricity, $20 a year.
Add up the energy used when we are not using our TVs, stereos, cable boxes (the list goes on and on), and you get the equivalent of a year’s output of 17 power plants. Investing in powerstrips can be extremely beneficial. Not only can you plug in multiple devices at once, but you can turn them all off conveniently and easily too.
