'Phantom energy' and 'energy vampires'
Phantom energy, also known as vampire power, refers to the electricity that gadgets and appliances waste when they are plugged in but switched off. Appliances with a timer, digital clock or display, standby mode, and other energy-consuming features continue to draw power even when not in use. Vampire power can account for up to 20% of your monthly electricity bill, with the average American household spending $165 to $440 per year on vampire energy costs.
Examples of appliances that consume vampire power include computers, modems, monitors, TVs, phone chargers, cable boxes, microwaves, and coffee makers. These appliances can consume a considerable amount of electricity even when not in use, with the U.S. Department of Energy estimating that approximately 10% of the average household electric bill is due to phantom energy loads.
To reduce phantom energy consumption, consider unplugging appliances when not in use, using power strips with on/off switches, or investing in smart plugs that allow you to control the flow of power to appliances remotely. You can also look for appliances with lower standby power usage and ensure that they are professionally maintained and kept in good repair to perform more efficiently.
In addition to phantom energy, it is important to be aware of energy vampires, which refer to people who drain your emotional energy. These individuals are often charismatic and may be found in your personal or professional life. They tend to exhibit narcissistic tendencies, struggle to take responsibility for their actions, and leave you feeling exhausted and overwhelmed. Learning to identify and respond to their toxic behavior can help you preserve your energy and protect yourself from emotional and physical distress.

Appliances to always keep plugged in
While unplugging unused appliances can help save electricity and reduce energy bills, there are some appliances that are essential and should remain plugged in at all times. Here are the appliances you should always keep plugged in:
Refrigerators and Freezers
Refrigerators and freezers are essential appliances that should always be plugged in to preserve food. Modern refrigerators are designed to be energy-efficient and don't consume excessive standby power. Unplugging them could lead to food spoilage and waste.
Stoves and Ovens
Stoves and ovens are often hardwired into your home's electrical system and are usually placed against a wall, making them impractical to unplug between uses. They typically don't draw significant standby power, so it's more convenient to keep them plugged in.
Dishwashers
Dishwashers tend to use very little standby power, usually only for digital displays. Unplugging them may not provide significant energy savings, and pulling them out from cabinetry could be more hassle than it's worth.
Routers and Modems
Even when no devices are plugged into them, routers and modems remain connected to the internet and continue to broadcast a Wi-Fi signal. Keeping them plugged in ensures that you can stay connected and access the internet whenever needed.
Smart Power Strips
Smart power strips or power strips with on/off switches are useful for managing multiple appliances or electronics. They allow you to control the flow of power to multiple devices at once, making it easier to turn them off when not in use without the need to unplug each device individually.
It's worth noting that large appliances should always be plugged directly into a properly grounded wall outlet. Power strips may not be able to handle the continuous high electrical demand of large appliances, and unplugging them could lead to safety hazards. Additionally, you can use plug-in power meters or smart home energy monitors to measure the actual electricity usage of your appliances and identify which ones are drawing significant phantom power.

Using power strips
Power strips are an excellent way to manage standby power use and keep track of all your different appliances. When you plug multiple devices into a power strip, you can cut standby power to all of them simultaneously by flicking the switch. Modern smart power strips can even detect when appliances are in standby mode and automatically cut off their power supply.
However, it is important to note that most power strips are not designed to handle the continuous high electrical demands of large appliances. Overheating or melting insulation could ignite a fire. Therefore, large appliances should always be plugged directly into a properly grounded wall outlet.
If you want to use power strips to manage your energy consumption, you can start by identifying which appliances are drawing significant phantom power and which ones are worth the effort to unplug. For example, coffee makers with programmable features or digital displays may draw a considerable amount of phantom power. In this case, you can plug the coffee maker into a power strip and turn off the power strip when the coffee maker is not in use.
Another way to identify which appliances are using the most energy is to use an electricity monitor. Plug-in power meters, such as a Kill-A-Watt meter, can measure the actual electricity used over time. You can plug the meter into an outlet and then plug your appliance into the meter to see real-time energy usage. This will help you determine which appliances are worth unplugging or plugging into a power strip to manage your energy consumption effectively.
