Britons waste the equivalent of around two power stations’ worth of electricity each year by leaving electrical appliances on standby.

(A survey by the Energy Saving Trust found that more than seven out of 10 people leave appliances on standby. A new product called “Bye Bye Standby” cuts power to any devices plugged into it when they’re not in use. According to their web site, the average UK household wastes £37 each year by leaving appliances on standby. I’m not sure how much this device costs, but I’m sure it would pay for itself in no time, especially if you have kids.)
