Energy efficiency is all about doing more with less - in terms of energy efficient households, this means getting as much useful power out of appliances while using as little energy as possible, and not letting any go to waste.
For instance, while old-style lightbulbs produce a lot of light, they also produce a lot of heat, which is a waste of energy. Energy-efficient lightbulbs produce the same amount of light, but very little heat, which means there is less energy wasted. This is the case with all energy-efficient household appliances.
You can also make your house more energy efficient by installing loft and cavity wall insulation to reduce the amount of heat that is lost through walls and the roof - simply improving your home's insulation could cut your annual energy bill by up to £390 per year.*
*£390 savings a year figure is for a 1940s 3 bed semi-detached home with a ten year old gas boiler and a gas price of 3.73p/kWh, when cavity wall insulation and loft insulation are installed. More modern homes save less. Individual savings depend on a large number of factors and the £390 quoted should be treated as a guide. †Based on installing a new A-rated condensing boiler and full set of heating controls in a gas-heated, semi-detached gas heated home with three bedrooms.
