Gadget-crazed Britons are absent-mindedly leaving energy-guzzling TVs and tablets switched on while not using them.
A new survey found every Brit has three devices to watch home entertainment and half (55%) admit leaving them on for at least an hour and a half per day.
Beverley Maguire, energy efficiency expert at E.ON said: “Add that up and it’s over three weeks every year.”
The poll for the supplier was based on research carried out among 2,009 British adults by Vision Critical in June 2014.
Maguire added: “As well as switching items off when they’re not being used, we’d also encourage people to think about energy ratings when they’re buying new gadgets and to find out more about how and where they’re using energy at home.”
The poll found many 18-24 year olds are abandoning TV to watch shows on tablets (24%), smartphones (19%) or games consoles (13%) instead.
Their parents and grandparents are likely to be more traditional, with 98% of over-65s viewing home entertainment on TV.
