Vampire Loads

The dreaded vampire loads

Perhaps you are familiar with an undesirable aspect of the electronic and IOT (Internet of Things) revolution: vampire loads. Vampire loads come from devices that use electricity even when they appear to be off. The primary culprits are chargers, set-top television boxes, instant-on televisions and gaming systems. There are others, but these four represent the major offenders.

Let’s look at how these vampire loads occur and why they are approaching 10 percent of average household electric use according to the Environmental Protection Agency.

Chargers take the 120 VAC (volts alternating current) power at the outlet and reduce it down to the voltage required by the connected device, usually 5 to 12 VDC (volts direct current). Obviously, when your device is charging, the charger is using electricity, but you might be surprised to learn that chargers are still using small amounts of energy even when they’re not connected to a device.

Television set-top boxes also consume energy when they appear to be inactive. Anytime the set-top box’s lights are on, it is using power. Like chargers, they use more when the television is on, but they are always working – even when the TV is off. This is especially true for those devices with a DVR function that records your favorite TV shows.

The instant-on television is another culprit. The intention of the “instant-on” feature is instant gratification for the viewer, meaning no waiting for the TV to turn on and warm up. Unfortunately, for that convenience, the TV must be on at nearly full power. So, in this mode, it can be a real energy drain.

The typical gaming console can use as much energy as a regular refrigerator even when it’s not being used. Make sure to check the console settings and disable automatic updates, which is where the energy drain comes from. Games on the console are frequently updated, which requires a lot of electricity.

So how does the average family combat these dreaded vampire loads? Garlic garlands? Silver bullets?

Fortunately, none of the remedies of fable are necessary. You just need to change how you handle these energy-sucking electronics. Here are a few suggestions.

  • Unplug chargers when not in use.
  • Invest in smart power strips. These look like normal power strips but have a twist; one of the outlets is the “master” that receives power all the time. The others are off. When the device connected to the master outlet turns on, the rest of the outlets receive power too. Ingenious and perfect for entertainment set ups. Have the television in the master outlet and when you turn it on, the set-top box, speakers, streaming devices, etc. will turn on too. They are also ideal for PCs and their peripherals.
  • Turn off the instant-on function on your TV. Turn off set-top boxes that do not contain the DVR functionality or use a smart power strip.
  • Disable automatic updates in gaming consoles and turn the console completely off when you finish using it.
  • When replacing any device or appliance, look for an EnergyStar rated product.

Vampire loads are a real problem that will only continue to grow as the digital age advances. But you can fight the vampires with vigilance and application of the recommendations above.
