Standby power, often called “phantom load” or “vampire power,” refers to the electricity consumed by electronic devices and appliances even when turned off or in standby mode. Many devices, such as televisions, chargers, printers, and microwaves, draw power continuously to support features like digital clocks, remote-control activation, or instant-on functionality. The amount of energy that a single device in standby mode uses may be minor, cumulatively, with multiple devices in a home, the amount will add up. Recent studies have shown that 10% of a household’s total energy consumption is standby power. This all can contribute to higher electricity bills and increased carbon emissions. 

So how can you reduce this energy usage? Reducing standby power is a simple and effective way to save energy and promote sustainability. One of the easiest ways to reduce standby energy consumption is by simply unplugging devices when they are not in use, such as chargers or kitchen appliances such as a toaster. The use of these appliances is minuscule compared to the amount of energy it will use while still plugged in. Some appliances or devices are harder to unplug consistently, such as TVs, microwaves, or computer monitors. In order to reduce standby power for appliances such as these, using smart power strips or surge protectors equipped with timers or motion sensors can help automatically cut off power to multiple devices when they are inactive. 

Another way to reduce standby consumption is investing in energy-efficient products and appliances. These types of appliances have an Energy Star certification which are designed to use minimal power when idle. This is a very sustainable choice for consumers who are looking to reduce their energy consumption, electric bill, and carbon footprint. 

Enabling energy-saving modes on devices can also help reduce standby power. Many modern devices, such as computers and TVs, have different settings that can put the device in a sleep mode or eco-mode that limits energy when the device is not in use. Lastly, conducting an energy audit of your home can help you identify which devices consume the most standby power. This is a more targeted approach.  

By addressing standby power, households can lower energy costs, reduce their carbon footprint, and help environmental conservation. While your efforts may seem small, the collective impact of reducing standby power usage can help combat climate change and promote a more sustainable future for everyone.
