The more stars an appliance has, the less energy it will use. A video cassette recorder adds up to 150 kilograms per year. Televisions, VCRs and stereos can generate up to 150 kilograms of greenhouse gas per year when in 'standby' mode. Turn them off at the power point when you leave the house for long periods.

Dishwashers can generate hundreds of kilograms each year.
They carry energy labels to help you choose energy-efficient models. To save on greenhouse gas, only run your dishwasher when it's fully loaded.
