Energy Saving Tips For Home

What is standby power?

• Standby power is the electricity consumed by an appliance when it is not performing its primary functions, but plugged in to a power source and ready to be used. For example : a television continues to draw a little power to maintain the control function after the user switches it off with the remote control device. Standby power is expressed in watts (W).

How much energy is consumed in standby mode? Why is it so important?

• The electricity consumption of different electric appliances in standby mode varies. Assuming that the standby electricity consumption for an appliance is 1 Watt and a family normally has about 10 to 20 electrical appliances* in standby mode, switching off all such standby appliances may reduce household electricity consumption by up to 3%.

*These appliances include broadband modem; Wi-Fi router; cordless telephone; desktop computer; computer monitor; printer; charger for mobile phone, tablet computer, notebook computer and backup battery pack; television; video player; digital video recorder; video game console; radio; electric fan; electric toothbrush and electric shaver.

Tips for reducing Standby Power Consumption

• Switch off appliances that are not in use, after use or before going abroad for a long period of time, and unplug them from power outlets to reduce standby power consumption.
• Use appliances with timer control or automatic power-off function. Do not leave them in standby mode for a long period of time.
• Remove battery charger from power socket outlet after charging is completed.
