Environmental impact
Standby power, also known as vampire power, phantom load, ghost load, or leaking electricity, refers to the electricity consumed by electronic and electrical appliances when they are not actively in use but remain plugged into the mains. Standby power is a significant contributor to global energy consumption, accounting for 10% of all electricity use worldwide. This has a substantial environmental impact, leading to higher carbon emissions and contributing to climate change.
The environmental impact of standby electricity is significant. Firstly, it results in the unnecessary consumption of energy, leading to higher carbon emissions and contributing to climate change. Globally, standby consumption accounts for 2% of total electricity usage and 1% of CO2 emissions. While this may seem insignificant, it is essential to recognize that this energy is wasted and could be saved by reducing standby power consumption. This wasted energy also has economic implications, as it contributes to higher energy costs for households and businesses.
Secondly, the manufacturing and distribution of electronic devices have environmental repercussions. As the demand for electricity increases, so does the strain on power generation, transmission, and distribution systems. This can lead to a greater reliance on fossil fuels and an increase in greenhouse gas emissions. Additionally, the production of electronic devices requires raw materials and resources, contributing to resource depletion and environmental degradation.
Standby power consumption also impacts the longevity of electronic devices. Devices that constantly draw power, even when on standby, may experience reduced battery life and require more frequent replacements. This contributes to the growing issue of electronic waste, as devices are discarded and replaced more frequently. The disposal of electronic waste can result in toxic materials seeping into the soil and water bodies, further damaging the environment.
Furthermore, the environmental impact extends beyond the direct consumption of standby power. Many devices with standby modes are designed to constantly detect software updates and respond to voice commands or remote controls. This background activity requires data centers and servers to be active and continuously consuming energy, even when the devices themselves are not in active use. The energy consumption of data centers contributes to their environmental impact, particularly in regions where power generation relies heavily on fossil fuels.
To mitigate the environmental impact of standby electricity, individuals, and industries can take several measures. Firstly, unplugging devices or using power strips to completely cut off power to appliances can effectively eliminate standby power consumption. Additionally, smart plugs or apps that automatically turn off electronics when not in use can be utilized. By reducing standby power, we can decrease energy consumption, lower carbon emissions, and contribute to the preservation of the environment for future generations.

Fire risk
Standby power, also known as vampire power, phantom load, ghost load, or leaking electricity, refers to the way in which electrical appliances consume electricity while on standby, despite not being actively in use. This occurs because some devices claim to be "switched off" on the electronic interface but are actually in a different state (standby mode) to power a clock or allow for remote control power-on.
Standby power can pose a fire risk, particularly in older cathode-ray tube display equipment (television and computer displays) that had high voltages and currents. Modern equipment is much less likely to catch fire, but it is not impossible. Televisions, in particular, have been reported to catch fire in standby mode.
To reduce the risk of fire, it is important to switch off devices completely when they are not in use for extended periods and to unplug them from the power source. This is especially important for older devices that may have higher standby power consumption.
Additionally, some devices, such as security systems, fire alarms, and digital video recorders, require continuous power to operate properly. However, electric timers can be used to disconnect these devices from standby, reducing the overall energy usage and fire risk.
It is worth noting that while modern electronics have lower standby power consumption, they can still contribute to energy waste and increased energy costs. To mitigate this, consider using energy-saving features such as turning off plugs at the wall, using power strips, or utilising smart plugs that automatically turn off electronics when not in use.

Government regulations
In the past, standby power was not a significant concern for government regulators. However, in the first decade of the 21st century, awareness of the issue grew, and it became essential for regulators to address it. By the middle of the decade, standby power consumption had reached several watts or tens of watts per appliance.
In response, governments in most developed countries implemented regulations to restrict standby power. These regulations, often referred to as the One Watt Initiative, limited the standby power of devices sold to one watt starting in 2010, with a further reduction to 0.5 watts in 2013. This initiative has helped to reduce standby power consumption significantly, with savings of up to 41% reported in some cases.
The European Commission has also played a role in regulating standby power. Since 2009, certain devices such as audio and video equipment, microwave ovens, and electric toys have been required to switch to a low-power mode, such as standby, after a reasonable amount of time. In 2021, washing machines and dishwashers were removed from the scope of these regulations, and cordless phones will follow in 2025. The Commission continues to work towards reducing the energy consumption of electrical and electronic household and office equipment.
In addition to regulations, governments have also promoted initiatives to help consumers reduce their standby power consumption. For example, energy-saving apps that link to smart meters and provide insights into energy usage have gained popularity. These apps can help users understand their energy consumption patterns and make informed decisions to reduce their standby power usage.
Looking ahead, the European Commission has revised rules for devices in networked standby, which will come into effect from 2027. These rules aim to limit the power consumption of these devices to between 2 and 7 watts, depending on the product. The expected savings from these revised rules are significant, with projections of additional savings of 4 TWh/year in energy consumption and related GHG emission reductions of 1.36 Mt CO2eq./year by 2030.
