Home entertainment
- A large screen TV, used 6 hours a day, can generate around half a tonne of greenhouse gas each year—more than a family fridge.
- So enjoy your big screen TV, just turn it off if you aren’t watching it!
- The most efficient conventional TVs around 76 centimetres generate a third as much greenhouse gas as big screen plasma and LCD TVs: check the specification plate for the lowest watts.
- Most home entertainment equipment uses some electricity when it is switched off, as well as when it’s operating! See Standby Power section.

Computers and laptops
- A laptop computer used 5 hours each day generates around 40 kilograms of greenhouse gas each year. Desktop computers used the same way can generate between 200 and 500 kilograms. More than half of this is from using the monitor.
- An LCD panel monitor generates around half as much greenhouse gas as a conventional monitor. And adjusting its brightness lower can cut emissions to a quarter.
- Switch computers and equipment off when they’re not in use. This cuts greenhouse gases, extends product life and avoids a potential fire hazard.
