So how much energy is being wasted by appliences being left on stand by?

"Britons waste the equivalent of around two power stations' worth of electricity each year by leaving TV sets and other gadgets on standby. "

British experts reckon that electrical equipment in sleep mode uses roughly 7TWh of energy and emits around 800,000 tonnes of carbon.

The average household has up to 12 gadgets on standby or charging.

It has been calculated that the CO2 emissions from electrical equipment being left on standby are equivalent to 1.4 million long-haul flights.

Estimated annual CO2 emissions from devices left on standby:

Stereos - 1,600,000 tonnes

Videos - 960,000 tonnes

TVs - 480,000 tonnes

Consoles - 390,000 tonnes

DVD players - 100,000 tonnes

Set-top boxes - 60,000 tonnes
