If you're user of appliances and gadgets, you always turn them off when you're not using them. But many electronics don't actually go all the way off, they're still on but using "standby power." Some examples of features that require standby power are:
internal clocks and sensors
external clock displays and panel display LEDs
remote control sensors;
battery recharger's and power-conversion packs
communications between a base unit and a portable unit (as in a portable phone).
Up to 10% f household electricity is wasted in homes around the world. Even when electrical equipment is not being used, they still draw away power, causing electricity bills to rise and contributing to 1 % of the world's carbon dioxide emissions, just from those electrical appliances supposedly being "off".
Each watt used costs an average of $1 US per year for any one of the 28 countries that is a member of the International Energy Agency (IEA). Although this may not seem like a lot, when you take into consideration the numerous appliances (usually 40 or more) scattered around a household, the cost can be enormous.
