The presence of a large number of electronic devices in a home helps increase the energy bill!
Simply plugging in a cell phone charger or an external power adapter for a portable computer uses energy even if the device is completely charged. The charger or adapter also uses energy even when it is not connected to a cell or computer. Think about unplugging chargers and adapters from the wall once your devices are completely charged.
Many devices continue to use electricity when they are in “sleep” mode, whether they are used to keep a clock or timer active or start up a device quickly.
Using a multi-plug socket with an on/off switch that simultaneously turns off all the devices plugged into it is a solution worth considering when trying to avoid unnecessary energy expenses. What is more, this will protect your devices from overload and overvoltage.
ENERGY STAR certification requirements address this issue by limiting the quantity of energy that can be used in “sleep” mode. For example, an ENERGY STAR certified television uses 40 to 50% less energy than a standard television. The same applies to ENERGY STAR computers which can use 70% less energy than standard computers in “sleep” mode.
