Leaving smartphones, tablets and other internet-enabled devices on costs consumers around the world $80billion (£46.6billion) a year. The International Energy Agency warned that the amount of wasted electricity would rise to $120 billion globally by the end of the decade with the proliferation of such devices connected to the internet.
The organisation criticised electronics manufacturers for making inefficient products. Even when devices are in standby mode they can use just as much electricity as when in use – accounting for about 16 per cent of all electricity consumed by British households. The energy agency said that switching off devices would save the same amount of electricity used by Canada and Finland combined by 2020.
