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
