Does your house eat energy?
UK homes are consuming much more electricity than previously thought, a report says.
The Energy Saving Trust (EST) discovered devices left on standby, or just left switched on, can make energy bills nearly one fifth higher.
That's double what they thought and Paula Owen, the report's main writer, said: "It was quite a shock."
Big energy eaters include fridges, freezers, microwaves, computers, and even mobiles on charge.
Attempts have been made to make products to help. The BBC show Dragons Den featured the Standby Saver - over a million were sold.
Switching off standby can save as much as £80 a year - that could pay for a new smartphone!
The EST wants people to buy devices which save energy, but they can be expensive. And some TVs left on standby are thought to last for longer. So it's confusing to know what's best!
