Are your devices sucking your wallet dry?
Your TV, HiFi sytem and mobile device chargers etc. are probably left plugged in almost permanently and you probably aren't too concerned about it. But Vampire devices like these can be responsible for huge amounts of wasted energy, by constantly taking a trickle of energy while on standby.
This is called ‘Standby Power’ or ‘Phantom Load’, many TV’s etc. have to keep certain circuits constantly energised to enable them to respond to the remote control to switch on.
