It is estimated that leaving electric appliances on stand-by uses about seven per cent of all electricity in UK homes. If some of your electrical equipment has not got an off button, only stand-by, or if you can't turn everything off at the mains every time, then an intelligent mains controller could be for you. Just put one in between the plug of your appliance and the socket and you can turn it off with a remote control handset. You save the energy while retaining the convenience.
