Turning off switches when appliances are not in use can save you money on your electricity bill. This is because many appliances continue to draw power when plugged in, even when they are turned off or on standby. This is known as phantom load, ghost load, or vampire power. Vampire power can add a significant amount to your electricity bill over time, especially for appliances that are always on, such as TVs, microwaves, and washing machines.

What You'll Learn
Standby power can cost you hundreds of dollars a year
Standby power, also known as vampire power, phantom load, or ghost load, refers to the electricity consumed by electronic devices when they are switched off or in standby mode. While modern appliances do not draw much power in standby mode, it can still cost you a significant amount over time.
According to experts, each watt of continuous standby power consumes about 9 kWh of electricity per year. This means that a device with a standby power of 5 watts will cost you just over $10 per year. While this may not seem like a significant amount, it can add up quickly when you have multiple devices in your home. For example, a laptop in sleep mode draws almost 16 watts, while a desktop computer draws over 21 watts.
Additionally, older appliances tend to use slightly more power on standby. Devices like VCRs, televisions, stereos, and kitchen appliances are known to consume electricity when switched off but still plugged into an outlet. For example, a microwave with a typical standby power of 0.5 watts will use more energy keeping its clock running than it will use to heat food over a year.
By being mindful of standby power and making small changes, you can save a significant amount of money on your electricity bill. For instance, you can turn off devices at the power point or use power strips to easily switch off multiple devices at once. You can also reduce standby power consumption on your computer by disabling certain features like Wake-on-LAN or "wake on modem."
While it may not be practical to unplug every device in your home, focusing on those with high standby power consumption or those that are not used daily can lead to noticeable savings. By adopting these habits and creating behavior changes, you can reduce your energy costs and contribute to environmental conservation by reducing the demand for electricity and fossil fuels.

Vampire power and phantom load
Vampire power can cost consumers a significant amount of money over time. In the United States alone, vampire power costs consumers more than $3 billion a year. Vampire power can also be a safety hazard, as it can increase the risk of electrical fires.
Many modern consumer electronics are designed for convenience and will continue to draw power as long as they are plugged in, even if they are turned off. This is often due to standby mode, which allows devices to be activated quickly without having to manually turn them on or plug them in. Devices with remote controls or smartphone app functionality often have vampire power.
Older devices and appliances typically have higher standby power usage, but newer devices may also have vampire power, especially if they have remote control or smart functions. Devices with built-in internal batteries, such as phones, can have their standby functions stopped by removing the battery.
To reduce vampire power and phantom load, individuals can unplug their devices when not in use, use power strips that can be switched off, or purchase energy-efficient products that are labelled as Energy Star-certified. Smart plugs can also be used to control and schedule the power to electric devices remotely.

Safety concerns
Turning off switches can help prevent electrical fires and reduce the risk of accidents. It is safer to turn off appliances when not in use, especially those with standby power or "vampire power," which can quietly draw electricity even when not in use. This not only saves energy but also reduces potential fire hazards.
Some appliances, such as TVs, toasters, and lamps, can consume electricity even when turned off but still plugged into an outlet. This is known as a "phantom load" or "vampire energy." It is important to unplug such devices or turn them off at the power point to mitigate safety risks.
Additionally, consider using power boards or a time-controlled switch to manage multiple appliances at once. This not only saves energy but also reduces the risk of electrical issues. It is a convenient way to ensure that multiple devices are turned off with a single click or automatically at specified times.
It is also worth mentioning that while it may be tempting to keep your Wi-Fi router on at all times, turning it off overnight or when away on holidays can be a safety precaution. Keeping your router on constantly can pose a security risk to your network if it does not receive regular updates. Turning it off and then back on can ensure the updates are installed, keeping your network secure.
Lastly, for devices with standby power, such as gaming consoles, turning them off at the wall can help prevent arcing when you plug them in. Arcing occurs when electricity jumps between two points, and it can be a safety hazard.

Energy efficiency ratings
Turning off appliances that are not in use can save you money on your electricity bill. Some appliances, such as TVs, toasters, and microwaves, continue to draw power even when they are turned off but still plugged in, a phenomenon known as "phantom load" or "vampire energy". This can add up to significant costs over time, so it is advisable to unplug such appliances or turn them off at the power point when not in use.
The energy efficiency rating for a washing machine or dishwasher, for example, will indicate its energy consumption per 100 washes, water consumption, cycle duration, and noise level. By choosing an A-rated washing machine over a D-rated one, consumers can save a significant amount of money on their electricity and water bills over the lifetime of the appliance. Similarly, choosing an A+++ rated tumble dryer over a B-rated one can result in substantial savings.
For ovens, the most energy-efficient options are those rated A+++, while gas rings are less efficient than electric hobs. Ovens with triple-glazed doors and fan-assisted cooking are also more energy-efficient as they help retain heat and cook food at lower temperatures. Microwave ovens are generally more energy-efficient than traditional ovens for cooking as they only heat the food and not the airspace inside.
In addition to appliances, energy efficiency ratings are also being considered for other products such as swimming pool pumps, heat pump water heaters, and external power supplies in Australia and New Zealand. These ratings help consumers identify products that will reduce their energy consumption and lower their energy bills, contributing to both financial savings and environmental sustainability.

Power boards and time-controlled switches
Power boards are a great way to save energy, particularly when it comes to standby power in the home. A power board allows you to quickly turn off multiple electronics in a room with just one click. This is especially useful for home entertainment systems and bedrooms, which often have multiple devices plugged in.
Smart power boards are becoming an increasingly popular option, as they can dynamically modify power distribution in response to actual demand and use trends. This means that, unlike conventional switchboards, smart power boards can prevent needless power usage, increasing energy efficiency and reducing energy waste. They can also be controlled via smartphone apps, making it easier to switch off appliances when not in use.
Smart lighting is another way to save energy, as it allows you to control light switches from anywhere using a smartphone app. This ensures that lights are never left on when not needed.
Time-controlled switches can also be used to save energy. For example, smart thermostats are devices that control a household's heating, ventilation, and air conditioning via a tablet or phone. They learn the user's habits and auto-adjust the settings to optimise energy usage.
Using power boards and time-controlled switches can, therefore, be an effective way to save electricity and reduce energy costs.
