How many mobiles and tablet devices are in your home and/or business? Are you a gadget fanatic with lots of plug in devices with adaptors?
With the advent of the smart phone and tablet devices such as the iPad, business and home energy bills are increasing accordingly. To make a small difference make sure you switch off plugs with chargers when they are not in use. Also, when purchasing a new gadget just ask what the power consumption is when the adapter is plugged in but the device is not attached. Your sales person should be able to point out if any energy saving features have been included in the adaptor for the device.
