Energy facts

The energy consumed each year by UK commerce and industry releases about 60 million tonnes of carbon into the atmosphere (sources: Digest of UK Energy Statistics, DTI and ETSU).
Through energy use, the average home emits more harmful CO2 gas than the average car (source: ETSU).
The average household spends approximately £400 on energy bills between October and March – about a third more than an energy efficient home (source: ETSU).
Domestic energy consumers spend approximately two-thirds of their total annual energy bill in the winter months (source: ETSU).
By turning down your thermostat by 1oC, or using one hour less heating a day, you could cut your fuel bills by 10% (source: BRECSU).
Installing loft insulation to a depth of at least 15cm (six inches) can save around 20% of your heating costs (source: EST).
Cavity wall insulation reduces heat loss through walls by up to 60%, and can save up to 40% on heating bills (source: ETSU/BRECSU).
Up to 20% of heat lost from a home can be through windows. Double-glazing can reduce this loss by up to 50% (source: ETSU).
Using just one energy-saving light bulb could save you £5 a year, and if every household installed one, we could power the lighting currently used in 2 million homes for a year (source: DETR).
If everyone boiled only the water they needed to make a hot drink, instead of filling the kettle every time, we could save enough electricity to run practically all the street lighting in the country (source: DETR).
