Switched off While Plugging in, Standby Power Is Worth Noting 关机不断电，待机能耗值得注意

Did you know that if your TV， computer and other appliances are plugged in， they are also draining electricity quietly—all day， every day—even when they are turned off？ Electric power consumed by products when they are switched off or in a standby mode is known as standby power （sometimes called vampire power or phantom power）.

你是否知道，如果你的电视、电脑和其他电器插上电源，即使它们已关机，它们也会一直在悄悄地耗电？产品关闭或处于待机模式时消耗的电能称为待机能耗（有时称为吸血鬼能耗或幻象能耗）。

Standby Power

待机能耗

Standby power refers to the way electric power is consumed by electrical appliances while they are switched off or in standby mode.

待机能耗是指电器关机或处于待机模式时所消耗的电力。

Under what circumstances will standby power consumption be generated？

什么情况下会产生待机能耗呢？

This only occurs because some devices claimed to be “switched off” on the electronic interface， but are in a different state from switching off at the plug， or disconnecting from the power point， which can solve the problem of standby power completely.

产生这种情况是因为一些设备只是在电子界面完成了所谓的“关机”，而没有拔掉电器插头或切断电源，只有断电才能彻底解决待机能耗的问题。

Add up Waste

积少成多的浪费

Standby power is difficult to detect because it is a waste of “add up to more”.

待机能耗难以被察觉，因为这是一种“积少成多”的浪费。

The Energy Saving Trust estimates that an individual could save around ?40 a year by turning off devices that are not using. Globally， standby consumption， both business and private， accounts for 2% of total electricity consumption and 1% of CO2 emissions.

据英国节能信托基金会估计，如果能消除待机能耗，每人每年可节省约40英镑（约合人民币330元）。全球范围内，公用和私用待机能耗之和占总用电量的2%，贡献了1%的二氧化碳排放量。

It is imperative to reduce unnecessary energy consumption. Here are a few energy saving tips：

降低非必要能耗势在必行，以下是几个节能小妙招：

①Use a power strip with switches. Power surge protectors typically have such switches and help protect your appliances and electronics. If you plug all of your products into a power strip and flip off the power strip when these items are not in use， they are truly off.

①使用带开关的电源板。电源浪涌保护器往往自带开关，有助于保护电器和电子设备。把家电插在同一个电源板上，不用的时候就直接关闭电源板，这样一来，所有电器的电源就都断开了。

②Unplug your products. Now， there are some products that you will want to keep plugged in， such as the digital alarm clock in your bedroom or the refrigerator. But there are many appliances that you may not need to have plugged in， such as a toaster oven.

②隨手拔掉插头。有些家电需要随时通电，如冰箱和卧室里的闹钟。但是很多电器没必要一直插着电源，如烤箱。

③Consider using energy-saving products. Many energy-saving products have lower standby power than other products.

③考虑使用节能电器。许多节能电器的待机能耗相对更低。
