Standby Power: An Energy Phantom in the Home

(391 words)

Remote controls, electronic timers and battery chargers are among the devices that few homes could – or would – do without in today's wired world. But there are significant if largely unknown costs to these modern conveniences, which are taking a heavy toll on household budgets and the environment.

Even when turned "off," many appliances and home electronics continue to use energy, referred to as standby power. Televisions and DVD players, for example, go into standby mode so that they are ready to receive signals from remote controls. Dishwashers may have timers that require a continuous supply of power, and many other appliances – from microwave ovens to coffee makers – have digital clocks. Battery chargers and external power supplies (e.g., for laptops) also draw power when they are plugged in but are not actively being used.

A typical Canadian household can have upwards of 20 pieces of equipment all using standby power at the same time. Although each device is using a relatively small amount of electricity, their combined consumption can be equivalent to operating a second refrigerator – and an empty one, at that!

In addition to representing a huge waste of money, the out-of-control use of standby power is generating unnecessary pollution and greenhouse gas emissions – a problem that comes into sharp focus when you consider the use of standby power on a national or global scale.

What can you do about the problem? Where feasible, unplug equipment or use a power bar to cut the circuit – this is the only way to be certain that an electronic device is not drawing power.

Another way to minimize standby power consumption is to purchase ENERGY STAR^® qualified products. Some types of equipment – home entertainment and computer products, for example – qualify for this international symbol of energy efficiency by dramatically reducing standby power consumption.

Buying energy-efficient products helps reduce air pollution and greenhouse gas emissions that contribute to climate change. The end result is more money in your pocket and a better environment for everyone, including future generations.
